Detailed Description
Example 1
Referring to the car door transferring device shown in fig. 1-6, the car door transferring device comprises a frame 1 and a lifting rack 10 arranged on the frame 1, wherein a supporting mechanism 11 is arranged on the lifting rack 10, a lifting mechanism 12 for driving the supporting mechanism 11 to move up and down is arranged on the frame 1, the top surface of the supporting mechanism 11 is supported on the outer plate molded surface of a car door A, and the supporting mechanism 11 comprises at least two placing positions for placing the car door A.
In the above-mentioned scheme, the door a needs to be transported to the press-fit die cavity for processing, and the feeding height of the press-fit die cavity is about 1.2 meters during actual production in a factory, so that the lifting frame 10 is required to transport the door a to a high position. Since the outer panel profile of the door a is smoother than that of the inner panel, the outer panel profile of the door a is placed face down on the support mechanism 11 at the time of transporting the door a to facilitate downstream transport of the door a, and scraping is not easily generated between the door a and the support mechanism 11. The supporting mechanism has at least two placing positions for placing the vehicle doors, and the transferring tool is not required to be switched again when the vehicle doors of different vehicle types are transferred, so that the time for changing the transferring tool is saved, and the production efficiency is improved.
In addition, the lifting mechanism 12 for driving the supporting mechanism 11 to move up and down can select various driving mechanisms such as an electric cylinder, an air cylinder, an oil cylinder and the like, and the electric cylinder driving is more convenient in the embodiment. In actual use, a pair of auxiliary telescopic rods are further arranged on two sides of the electric cylinder, and the two auxiliary telescopic rods are identical in length and symmetrically distributed relative to the electric cylinder, so that the auxiliary lifting rack 10 cannot incline in the vertical displacement process.
Preferably, the supporting mechanism 11 is detachably connected to the frame 1, and the supporting mechanism 11 is selectively installed on the frame 1 at least two installation positions. The supporting mechanism 11 can be used for transferring the vehicle doors A with larger difference of the profiles of the outer plates of different vehicle types by changing the installation positions of the supporting mechanism on the frame 1, so as to form the placement positions of the different vehicle doors A.
Specifically, the support mechanism 11 includes a left row roller set 11A and a right row roller set 11B, the left row roller set 11A and the right row roller set 11B are formed by unit rollers 111, the roller top profiles of the unit rollers 111 in the same row are coplanar and the roller cores are parallel, the roller top surfaces of the left row roller set 11A and the right row roller set 11B are splayed with upward openings, and the intersecting lines of the roller top surfaces of the left row roller set 11A and the right row roller set 11B are horizontally oriented as a whole.
In the above scheme, any two adjacent unit rollers 111 in the same row may be arranged at intervals, or may abut against each other, that is, the adjacent two roller profiles are arranged tangentially. The preferred interval arrangement of this embodiment can save the number of unit rollers 111 of each row of roller sets, and also reduce the wear of the unit rollers 111. The roller top profiles of the unit rollers 111 in the same row are coplanar and the roller cores are parallel to ensure that the door a can be smoothly conveyed on the unit rollers 111. Because the profile of the outer plate of the car door A is the outwards-raised cambered surface, the roller top surfaces of the left row roller set 11A and the right row roller set 11B are splayed with upward openings, the profile of the outer plate of the car door A can be better attached, the car door A cannot slide from the side of the supporting mechanism 11 under the action of gravity, and the whole intersecting line of the roller top surfaces of the left row roller set 11A and the right row roller set 11B is horizontal, so that the car door A cannot slide along the conveying direction.
For conveniently and rapidly transferring the vehicle doors A of different vehicle types, the left row roller set 11A comprises a left row first roller set 11A1 and a left row second roller set 11A2 which are arranged outside, below and inside, and the left row second roller set 11A2 is detachably connected with the frame 1. When the left row second roller set 11A2 and the right row roller set 11B are used as the placement positions for the transfer door a, the left row first roller set 11A1 does not interfere with the door a because the left row second roller set 11A2 is Yu Zuolie higher than the first roller set 11 A1. When the vehicle door A of another vehicle type is required to be transported, the left row of second roller sets 11A2 can be directly disassembled, and the left row of first roller sets 11A1 and the right row of roller sets 11B can be used as placement positions of the new vehicle door A.
In order to realize detachable connection of the supporting mechanism 11 on the frame 1, the frame 1 is provided with a bar-shaped supporting plate 112, the unit rollers 111 in the same row have the same diameter, the lower ends of the wheel shafts are fixed at the upper ends of the bar-shaped supporting plate 112, and the planes of the wheel shafts of the unit rollers 111 at the opposite sides form a splayed shape with upward or oblique included angles. In the above scheme, the unit rollers 111 in the same row are arranged on the same bar-shaped supporting plate 112, and the roller top surface of the unit roller 111 is higher than the upper edge of the bar-shaped supporting plate 112, so that the bar-shaped supporting plate 112 is prevented from colliding with the outer plate profile of the vehicle door A. In this embodiment, as shown in fig. 3, the lower edge of the bar-shaped supporting plate 112 is inserted into a bar-shaped groove on the frame 1 adapted to the bar-shaped supporting plate 112, so as to facilitate the installation and the removal of the bar-shaped supporting plate 112. The bar-shaped supporting plate 112 may be provided as a folded plate with a folded edge parallel to the row of the unit rollers 111, and the upper half thereof is inclined inwards so that the faces of the unit roller 111 shafts on the opposite sides form a splayed shape with an upward or oblique included angle.
Example 2
On the basis of the prior art of the embodiment 1, the rack 1 is further provided with a conveying rack 20, the conveying rack 20 is adjacently arranged at the downstream end of the supporting mechanism 11 for conveying the vehicle door A, the conveying rack 20 is provided with a conveying belt mechanism 21 for conveying the vehicle door A, and the supporting mechanism 11 can be lifted to a transfer position which is level with the top surface of the conveying belt mechanism 21 for supporting the vehicle door A, or lowered to a loading position below the transfer position. The two conveyor belt surfaces 211 of the conveyor belt mechanism 21 are splayed with openings upwards, and the intersecting line of the conveyor belt surfaces 211 is horizontally oriented as a whole.
Fig. 4 to 6 show the vehicle door a in two states of the loading level lifting and the conveying of the conveyor belt mechanism 21, respectively, and the device of the present invention transfers only one vehicle door a at a time.
In order to provide more equipment space for the process of the pressing die cavity, the car door A needs to be horizontally fed into the pressing die cavity through the transfer device, and most car door transfer tools in the prior art directly carry the car door A onto a liftable conveyor belt, and then the conveyor belt and the car door A are lifted to a proper height and then conveyed. When the door A is manually carried, the outer plate of the door A is placed on the conveyor belt to generate impact force on the conveyor belt, so that the conveyor belt is easy to wear after long-time use, and the maintenance cost is increased. Moreover, when the impact force generated by placing the vehicle door A is large, the surface of the outer plate of the vehicle door can generate a pit, so that reworking repair is needed, and even the vehicle door is directly scrapped. The invention separates the procedures, and sets up the lifting rack 10 and the conveying rack 20 respectively, the operator firstly places the car door A on the supporting mechanism 11 at the loading level, so that the impact force generated by placing the car door A is borne by the supporting mechanism 11 of the lifting rack 10 instead of the conveying belt mechanism 21, after the supporting mechanism 11 is lifted to the switching position, the car door A is horizontally pushed onto the conveying rack 20, and the car door A is conveyed into the pressing die cavity through the conveying belt mechanism 21. This transfer process directly eliminates the impact between the door a and the conveyor belt face 211 in the direction of gravity, and simply and conveniently solves the above-described problem. The belt conveyor 21 may be driven by a motor to carry out belt conveyance.
In order to facilitate positioning the placement position of the vehicle door a, the sides of the supporting mechanism 11 and the conveyor belt mechanism 21 are respectively provided with a guide roller set 22, the guide roller set 22 is composed of unit guide rollers 221, the diameters of the unit guide rollers 221 in the same row are the same, the wheel shafts are coplanar and perpendicular to or close to the bottom edge of the vehicle door a, and the roller circumferential surface of the guide roller set 22 abuts against the bottom edge of the vehicle door a.
In the above scheme, when the vehicle door a is placed on the supporting mechanism 11, the guiding roller set 22 can be used as a reference object of the vehicle door a, and the bottom edge of the vehicle door a can be directly abutted against the wheel surface of the corresponding guiding roller set 22, so that the transferring posture of the vehicle door a can be quickly adjusted. Meanwhile, the guide roller set 22 can also prevent the car door A from accidentally slipping off on the side of the guide roller set 22. The wheel shaft of the unit guide roller 221 on the elevating rack 10 is in a plumb direction, and the wheel shaft of the unit guide roller 221 on the conveying rack 20 is slightly inclined with respect to the plumb surface, but both are perpendicular or nearly perpendicular to the bottom edge of the vehicle door a. The guide roller set 22 also guides the door a during translation as it is pushed from the transfer station to the transfer station 20 and delivered into the compression mold cavity.
It should be further noted that the guide roller set 22 shown in fig. 1 and 2 is connected to a flap which can be moved up and down along the edge of the transfer carriage 20 to adjust the position to fit the doors a of different vehicle types.
In order to protect the door a from being damaged by collision during the transferring process, the supporting surface of the supporting mechanism 11 and the roller circumferential surface of the unit guiding roller 221 are made of rubber materials. Preferably, annular grooves parallel to each other may be further provided on the roller circumferential surfaces of the unit roller 111 and the unit guide roller 221, respectively. The annular groove on the circumferential surface of the unit roller 111 can reduce noise generated when the door a is pushed; in the loading position or the transfer position, the bottom edge of the vehicle door A can be directly inserted into the annular groove on the peripheral surface of the unit guide roller 221, so that the vehicle door A is not easy to slip.
The vehicle door A comprises a left vehicle door and a right vehicle door which are symmetrical in shape, and in order to facilitate the conveying bench 20 to convey different left and right doors, the conveying bench 20 is in running fit with the upper end of the upright post 23 below the conveying bench, and a limiting mechanism 24 for limiting the relative rotation of the conveying bench and the upright post is arranged between the conveying bench and the upper end of the upright post. In the above-described embodiment, the column 23 is rotatably connected to the frame 1 so that the transfer gantry 20 can rotate on the frame 1 around the center of the conveyance path of the conveyor belt mechanism 21. Preferably, the limiting mechanism 24 is a positioning pin, which is disposed at one side of the rotation center and penetrates through the conveying rack 20 and the frame 1. The conveying bench 20 is also provided with two positioning pin holes symmetrically arranged relative to the upright 23. When the left and right doors are required to be switched, the positioning pins are only required to be pulled out, the conveying rack 20 is wholly rotated for 180 degrees around the upright posts 23, then the positioning pins are reinserted, the conveying direction of the belt of the conveying belt mechanism 21 is changed, and the switching of different conveying postures of the conveying rack 20 can be completed.
