Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6As shown, a clamping fixture for machining the end face of a balance shaft includes a main body 100 with an overall frame structure, a drive unit 200 mounted on top of the main body 100, a support unit 300 mounted inside the main body 100, and a reinforcing unit 400 disposed on one side of the support unit 300. The main body 100 is used to hold the balance shaft, and the drive unit 200 is located above the balance shaft to fix its top. The drive unit 200 includes an electric push rod 210 bolted to the top of the main body 100, an upper wrapping member 220, and a pressing member 230. The electric push rod 210 provides power support for the overall structure, and the upper wrapping member 220 is raised and lowered inside the main body 100. For longitudinal positioning of the balance shaft, at least two extrusion pieces 230 are provided, respectively installed on both sides of the upper wrapping piece 220. A slot 240 for placing the extrusion piece 230 is provided on the inner wall of the main body 100. The extrusion piece 230 fits into the slot 240 to guide the lifting and lowering of the upper wrapping piece 220. The support part 300 controls the balance shaft both longitudinally and laterally. The support part 300 includes a lower wrapping piece 310 with an open top, a movable piece 320 disposed between the main body 100 and the lower wrapping piece 310, and a stabilizing piece 360 ​​fused inside the main body 100. The top of the movable piece 320 is flush with the lower wrapping piece 310. The tops of the components are flush with each other. The lower wrapping component 310 is located inside the main body 100. The top of the moving component 320 has a groove 350. The pressing component 230 descends and comes into contact with the groove 350, pressing the moving component 320 to move it, so as to fix the lateral position of the balance shaft laterally. The stabilizing component 360 is used to control the movement range of the moving component 320 and limit the position of the balance shaft. The reinforcing component 400 is installed inside the main body 100. The groove 350 moves towards the position of the stabilizing component 360. The groove 350 and the stabilizing component 360 cooperate to clamp the balance shaft and limit its lateral movement range. The moving component 320... The surface is provided with several raised structures, and the surface of the connecting groove 330 is provided with several through grooves that cooperate with the raised structures. When the raised structures pass through the through grooves, they can reinforce the position between the sliding groove 350 and the connecting groove 330, and increase the clamping effect on the balance shaft. The top of the moving part 320 is fixedly connected to the connecting part 340, and the bottom of the lower wrapping part 310 is provided with the connecting groove 330. The connecting part 340 slides inside the connecting groove 330, thereby increasing the stability of the moving part 320 when moving. On this basis, the cooperation between the connecting part 340 and the connecting groove 330 can also limit the movement range of the moving part 320. The connecting part 340 is designed to be wider at the top and narrower at the bottom.

[0016] The reinforcing part 400 includes a locking member 410 fused inside the main body 100, a reinforcing member 420 welded to the surface of the locking member 410, and a spring 430 disposed on the surface of the reinforcing member 420. It is used to support the other end of the balance shaft. The locking member 410 and the stabilizing member 360 are respectively disposed on both sides inside the main body 100, which can stably support the balance shaft and ensure that the balance shaft can be stable in a horizontal position. The reinforcing member 420 is attached to the inner wall of the main body 100. There are at least two springs 430 and they are symmetrically arranged. One end of the spring 430 is fixed to the surface of the moving member 320. After the compression of the moving member 320 is released, the moving member 320 moves in the opposite direction and resets under the action of the elastic force of the spring 430. The reinforcing member 420 restricts the movement range of the moving member 320. After the moving member 320 moves, the connection between the protrusion structure and the through groove is released, and the clamping of the balance shaft by the moving member 320 and the stabilizing member 360 is released.

[0017] Working principle: The balance shaft is placed inside the main body 100. The electric push rod 210 is activated to drive the upper wrapping part 220 to descend. At the same time, the extrusion part 230 descends and limits the two sides of the balance shaft. The extrusion part 230 is stuck in the slot 240 to reinforce the position of the upper wrapping part 220. The upper wrapping part 220 and the lower wrapping part 310 cooperate to wrap the upper and lower surfaces of the balance shaft respectively, thereby restricting the longitudinal movement of the balance shaft. At the same time, the descent of the extrusion part 230 can drive the moving part 320 to move. The moving part 320 moves to the position of the stabilizing part 360. The protruding structure is stuck in the through groove. The moving part 320 and the stabilizing part 360 cooperate to clamp the balance shaft and maintain the lateral position of the balance shaft. Thus, the longitudinal and lateral positions of the balance shaft are fixed to ensure the stability of the balance shaft in the subsequent processing.
