The specific embodiment of the present invention will be described in further detail below in conjunction with accompanying drawings 1-5.

A workbench lifting device.

As shown in Figure 1, a workbench 2 can be lifted and lowered on the top of the fuselage 1, and a swing arm 3 for controlling the lift of the workbench 2 is rotatably arranged in the fuselage 1, and the upper end of the swing arm 3 is fixedly connected with the workbench. Table 2, the lifting height of the workbench 2 can be controlled by adjusting the inclination of the swing arm 3, the side of the swing arm 3 is connected with a swing mechanism 4 for controlling its rotation angle, and the fuselage 1 is equipped with a The adjustment device 5 that the mechanism 4 moves back and forth, the other end of the adjustment device 5 extends out of the fuselage 1 and is connected with the adjustment nut 5, by rotating the adjustment nut 5, the front and rear positions of the adjustment device 5 will be changed, and the front and rear movement will be performed, thereby changing the swing The degree of inclination of the mechanism 4 adjusts the lifting height of the workbench 2. Every time the adjustment nut 5 rotates an angle, the height of the workbench 2 will change. Therefore, high-precision lifting adjustment can be performed to achieve high-precision planing effects.

Referring specifically to Fig. 2, mounting holes 6 are provided on both sides of the fuselage 1, and a lower rotating shaft 7 is rotatably arranged between the two mounting holes 6, and the outer circumference of the lower rotating shaft 7 is provided with the swing arm 3. , so the swing arm 3 can only rotate with the lower rotating shaft 7 as the axis, and the upper end of the swing arm 3 is fixedly connected with the workbench 2. When the swing arm 3 rotates, it will drive the workbench 2 to go up and down, wherein the swing arm 3 and the workbench 2. The specific connection structure is: the two ends of the swing arm 3 are respectively extended with installation parts 8, and an upper rotation shaft 9 is fixed between the two installation parts 8, and the swing arm 3 passes through the upper rotation shaft 9. The two ends are fixedly connected with the workbench 2, and the assembly is more convenient.

3 and 4, one end of the adjusting rod 10 extends out of the fuselage 1 and is formed with an adjusting part 12. The outer periphery of the adjusting part 12 is formed with an adjusting thread, and the adjusting rod 10 forms a thread with the adjusting nut 13 through the adjusting thread. Connection, by rotating the adjusting nut 13, the forward and backward movement of the adjusting rod 10 can be controlled. This principle is well known to those skilled in the art. For details, refer to the working principle of the screw nut. The lower end of the movable seat 11 is equipped with a hinged seat 14. One end of the adjusting rod 10 is equipped with a hinged joint 15, which is rotatably installed in the hinged seat 14, so when the adjusting rod 10 moves forward, the lower end of the movable seat 11 will be pushed backward, And deflection occurs, so that the angle changes, the upper end of the movable seat 11 is connected with the side of the swing arm 3, and finally the inclination of the swing arm 3 is changed to adjust the height of the workbench.

Referring specifically to Fig. 3, the adjusting device 5 includes an adjusting rod 10 and an adjusting nut 13, the adjusting nut 13 is sheathed on the outer periphery of the adjusting part 12, by turning the adjusting nut 13, the adjusting rod 10 will move forward and backward, when adjusting When the rotation angle of the nut 13 changes, the adjustment rod 10 will move a certain amount to convert the rotary motion into a linear motion, which has the characteristics of high precision, reversibility and high efficiency, and has very small frictional resistance, and the adjustment is very labor-saving .

See Fig. 5 specifically, it is the specific hinged structure between the adjusting rod 10 and the movable seat 11: cylinders 16 are respectively formed on both sides of the hinged joint 15, and a rotation hole for the cylinder 16 to rotate is opened on the hinged seat 14 17, the hinged head 15 is rotatably installed in the rotating hole 17 through the cylinder 16, so when the adjusting rod 10 moves forward, the angle between the hinged seat 14 and the hinged head 15 will change, and at the same time due to the movable seat 11 The upper end of the upper end is fixed and cannot move, and can only rotate. When the lower end of the movable seat 11 rotates, it will drive the parts connected to its upper end to rotate simultaneously.

See Fig. 5 specifically, introduce the specific connection structure of movable seat 11 and connecting plate 18 below: the upper end of described movable seat 11 is affixed/welded with connecting plate 18, offers first fastening hole 19 on connecting plate 18, swing arm There is a second fastening hole 20 on the side of the 3, and the fasteners are used to penetrate the first fastening hole 19 and the second fastening hole 20 in sequence, so as to achieve the fixed connection between the connecting plate 18 and the swing arm 3. The connection structure is simple , easy to disassemble.

The specific working process of this program is as follows: When the lifting height of the workbench 2 needs to be adjusted, the following operations are performed. Referring to Figure 3, the adjusting nut 13 is first rotated. Since the left end of the adjusting rod 10 is connected with the adjusting nut 13 through the adjusting thread, the adjustment The rod 10 will move linearly, the adjusting rod 10 will move to the right, and every time the adjusting nut 13 rotates an angle, the adjusting rod 10 will be displaced, which can realize high-precision adjustment, thereby pushing the lower end of the movable seat 11 inward, so that The angle of the movable seat 11 changes, thereby driving the swing arm 3 connected thereto. Referring to FIG. The workbench 2 is fixedly connected, so when the swing arm 3 rotates, the height of the workbench 2 will change accordingly, thereby achieving the function of lifting the workbench 2.

The working principle of the movement between the adjusting rod 10 and the adjusting nut 13 can refer to the working principle of the screw nut, so it will not be explained in detail here.
