Description

Aluminum rod clamping mechanism

technical field

The invention relates to the technical field of mechanical control, in particular to an aluminum rod clamping mechanism.

Background technique

Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. The casting process of aluminum rods is to inject the molten aluminum in the melting pot into the deep well casting system, and after cooling, cast it into cylindrical rods or rectangular rods of different specifications, collectively referred to as aluminum rods. Generally, the aluminum rods lifted from the deep well casting system are relatively long, but during transportation or actual use, an aluminum rod cutting device needs to be used to cut them into relatively short segments.

The existing aluminum rod cutting device includes a cutting machine and conveying tracks located on both sides of the cutting machine. The conveying track is used for conveying aluminum rods. The conveying track includes two slide rails, and several conveying rollers are arranged between the two slide rails. When cutting aluminum rods, place the aluminum rods to be cut on the conveyor track on one side of the cutting machine, and manually control the aluminum rods to move toward the cutting machine. However, because the rollers are smooth, the aluminum rods are easy to slide when placed on them. Especially for cylindrical aluminum rods, the operator must hold the aluminum rods while cutting to avoid the aluminum rods from swinging due to the force generated by the cutting machine during the cutting process. If the swing occurs, it will affect the aluminum rods. The flatness of the cut leads to an increase in scrapped aluminum materials, and secondly, it will inevitably lead to injury of the operator.

Contents of the invention

The present invention aims at the above-mentioned existing technical problems, and provides a clamping mechanism that prevents aluminum rods from swinging on the conveying track during the cutting process.

In order to solve the above technical problems, the present invention provides the following basic technical solutions: the aluminum rod clamping mechanism includes two clamping parts, and the two clamping parts are respectively arranged on the two slide rails of the conveying track; The clamping parts each include a fixed block, a spring, and a movable block connected to the slide rail. One side of the fixed block is provided with a groove, one end of the movable block is hinged in the groove, and the other end of the movable block is connected to the One end of the spring, the other end of the spring is connected in the groove.

Working principle of the present invention: when the aluminum rod clamping device of the present invention is in use, the fixed block is fastened on the slide rail, and the sides with grooves on the two fixed blocks are opposite, and one end of the movable block is hinged on the In the groove, the other end is connected to the groove through a spring, and the end with the spring is close to the cutting machine, and the aluminum rod is pushed from the hinged end of the movable block to the end connected to the spring of the movable block. Due to the expansion and contraction of the spring, in the natural state, The spring is in a stretched state, and the movable block is pushed out of the groove and the end connected to the spring is kept away from the groove. Since the movable block is also hinged with the groove, the movable block is in contact with the aluminum rod during the process of pushing the aluminum rod on the conveying track. Extruded by the aluminum rod, the spring is gradually compressed, and the movable block rotates around its hinged end, so that the aluminum rod is located between two opposite clamping parts, and then the aluminum rod is limited and fixed.

The beneficial effect of the present invention is: the solution sets the clamping parts on the slide rails on both sides of the conveying track, so that the side with the groove on the fixed block is placed directly opposite, so that the movable blocks that are stretched and contracted by the spring are opposite. The expansion and contraction of the spring and the hinged connection are used to realize the rotation, so that the aluminum rod passes between the two clamping parts, and the aluminum rod is clamped and fixed by the movable block using the principle of action force and reaction force, which solves the need for manual labor in the prior art. It is safe and reliable to hold the aluminum rod to avoid the problem of swing, and avoid personal injury in this link.

The following is the optimization of the basic technical solution:

Optimization scheme 1: the movable block includes a booster section and a limiting section, the side of the limiting section in contact with the aluminum rod is a plane, and the side of the booster section in contact with the aluminum rod is a slope. In this setting, the booster section with a slope helps to push the aluminum rod smoothly on the conveying track and reduces resistance; while the limiting section with a plane can increase the contact area with the aluminum rod and reduce the impact during the advancement process. At the same time, it strengthens the effect of limiting and fixing the aluminum rod.

Optimization scheme 2, based on optimization scheme 1, a ratchet is provided on the plane of the limiting section, the teeth of the ratchet are located on the outer edge of the ratchet, the ratchet is equipped with a pawl, the lower section of the pawl is hinged with the wall of the limiting section, and the ratchet The lower end of the pawl is toothed, and the pawl is engaged with a positioning rod. The middle section of the pawl and the positioning rod is provided with a return spring, and the upper section of the pawl is also hinged with the wall of the limiting section. This optimization scheme is set up to enhance the clamping and fixing effect of the mechanism on the aluminum rod. When cutting an aluminum rod with a light weight, it is still inevitable to be slightly swayed by the force of the cutting machine, because the distance between the two movable blocks will inevitably increase when the aluminum rod oscillates. A ratchet is set on the contact surface of the rod, and the ratchet can only rotate in one direction. When the aluminum rod is fixed, the ratchet drives the positioning rod to support the positioning rod at the bottom of the groove, preventing the spring from being further compressed, and will not increase the two The spacing between each movable block makes the fixing effect better.

The third optimization scheme is based on the second optimization scheme: several irregularly arranged protrusions are arranged on the plane of the limiting section. Because the purpose of setting the limiting section is to enhance the effect of fixing the aluminum rod, in order to further enhance this effect, a number of irregularly arranged protrusions are set on the plane of the limiting section to increase the distance between the aluminum rod and the limiting section. The friction and resistance increase, so the effect of avoiding the shaking or swinging of the aluminum rod is better.

The fourth optimization scheme is based on the above scheme: the fixed block is provided with a chute for the slide rail to be embedded in, one side of the chute is provided with a threaded hole, and the threaded hole is internally threaded with a screw. Such setting is convenient to take off the fixed block, the movable block and the spring connected to the fixed block, and the position of the clamping part can be moved at will, so it is convenient to determine the position of the fixed block according to the actual situation, and the fixed block can be reassembled by the screw rod. fixed on the slide rail.
