After returning to its original position, the spring drives the U-shaped iron shell to move and reset, and the lower arm body has the function of anti-collision warning protection, so that when a collision occurs, the lower arm of the machine will not be damaged, and huge losses will not be caused, which brings great convenience to the user.

Description

Technical Field

[0001] The invention relates to the technical field of anti-collision equipment, in particular to a lower arm anti-collision mechanism. Background Art

[0002] When the wire cutting machine is working, the lower arm is fixed, the slide plate will do reciprocating motion, and the clamp body can be adjusted in the T-slot on the base. If the base still moves at the maximum stroke after the clamp body is adjusted inward, the clamp body will collide with the lower arm (which will occur when there is an operation error), causing the lower arm of the machine to collide with the clamp body, which may cause the lower arm to break and damage, resulting in huge losses;

[0003] However, the lower arm body of the existing wire cutting machine does not have the function of anti-collision warning protection, which causes damage to the lower arm of the machine when a collision occurs, causing huge losses and bringing great inconvenience to the user. For this reason, we propose a lower arm anti-collision mechanism to solve the above problem. Summary of the invention

[0004] In view of this, the embodiments of the present invention hope to provide a lower arm anti-collision mechanism to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0005] The technical solution of the embodiment of the present invention is implemented as follows: a lower arm anti-collision mechanism, including an anti-collision warning mechanism and a fixing mechanism, wherein the anti-collision warning mechanism includes a lower arm body, a circular groove, a circular through hole, a guide rod, an M4 countersunk screw, a spring and an anti-collision switch;

[0006] Two circular grooves are provided on the front and rear sides of the lower arm body, and a same circular through hole is provided between the inner walls of the two corresponding circular grooves close to each other. A guide rod is slidably connected in the circular through hole, and the front and rear ends of the guide rod respectively pass through the corresponding circular grooves and extend to the outside of the lower arm body. A U-shaped iron shell is provided on the outside of the lower arm body, and the U-shaped iron shell is sleeved on the outside of the two guide rods. The guide rod is threadedly connected to the U-shaped iron shell by an M4 countersunk screw, and the setting of the M4 countersunk screw has a locking effect.

[0007] Further preferably, the inner walls of the two corresponding circular grooves that are close to each other are fixedly connected with springs, and the ends of the two corresponding springs that are far away from each other are respectively fixedly connected to the front inner wall and the rear inner wall of the U-shaped iron shell, and the setting of the springs achieves an automatic reset effect.

[0008] Further preferably, the spring movable sleeve is arranged on the outer side of the corresponding guide rod, and two grooves are provided on the front and rear sides of the lower arm body, and the setting of the grooves has the effect of installing an anti-collision switch.

[0009] Further preferably, the bottom of the groove is opened, and an anti-collision switch is provided in the fixed sleeve in the groove. The setting of the anti-collision switch triggers a limit signal to achieve an emergency stop effect of the equipment.

[0010] Further preferably, a lower nozzle is provided on the left side of the lower arm body.

[0011] Further preferably, a lower guide wheel seat is provided on the left side of the lower arm body, and the lower guide wheel seat is located below the lower nozzle.

[0015] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0016] When the outer side of the clamp body of the present invention contacts the outer side of the U-shaped iron shell, the U-shaped iron shell drives the guide rod to move to compress the spring, and the U-shaped iron shell contacts the anti-collision switch, and the anti-collision switch triggers a limit signal to realize an emergency stop of the equipment. After returning to its original position, the spring drives the U-shaped iron shell to move and reset, and the lower arm body has the function of anti-collision warning protection, so that when a collision occurs, the lower arm of the machine will not be damaged, and huge losses will not be caused, which brings great convenience to the user.
