[0022] The rear axle refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-bridges and can implement half-bridge differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels, in which a gear set for transmission will be assembled;

[0023] When manufacturing a gear blank, it is necessary to fix the blank in place before performing detailed drilling operations. In existing technical means, manual fixing is usually used, which consumes a lot of manpower and has certain operational risks.

[0024] First, place the workpiece to be punched in the middle of the workbench 2, and then turn on the motor 24. The motor 24 drives the threaded rod 23 to rotate. When the threaded rod 23 rotates, the threaded sleeve 25 does not rotate with it under the limit of the limit slide groove 22, but slides inside the limit slide groove 22, so that the movable shift plate 26 can be brought closer to the workpiece to clamp and fix the workpiece, which is convenient for the next operation of the punching assembly 30. When the movable shift plate 26 moves, the positioning slide bar 31 slides inside the positioning slide groove 28, which can further standardize the moving track of the movable shift plate 26.

At the same time, no manual assistance is required, thus avoiding safety accidents during the drilling operation, and effectively ensuring the smooth progress of the drilling operation and the safe use of the device.

[0026] In other embodiments, the present embodiment discloses, please Figure 3 As shown, a clamping block 27 is provided on the inner side of the movable moving plate 26 , and the length of the clamping block 27 is 0.8 times the length of the movable moving plate 26 ; through this design, the workpiece can be better fixed, and at the same time, the existence of the clamping block 27 will not hinder the normal operation of the positioning slide rod 31 .

[0027] In other embodiments, the present embodiment discloses, please Figure 3 As shown, lubricating grease is provided at the connection between the threaded sleeve 25 and the threaded rod 23, and the width of the movable shift plate 26 is 0.5 times the width of the workbench 2; through this design, the connection and rotation between the threaded sleeve 25 and the threaded rod 23 can be smoother to avoid jamming.

[0028] Embodiment 2:

[0029] In other embodiments, the present embodiment discloses, please Figure 1 , Figure 2 , Figure 4 As shown, it also includes a material receiving mechanism, which includes a material discharge hole 20, which is opened at the center point of the workbench 2, a slag receiving chamber 11 is opened on the top end face of the device base 1, a sealing plate 13 is movably connected to the outside of the slag receiving chamber 11, and a rack 14 is provided on the bottom end face of the sealing plate 13, a fixed plate 12 is provided on the outside of the device base 1, and a semi-open top end of the fixed plate 12 is opened with an empty slot 15, a rotating rod 17 is rotatably connected to the inside of the empty slot 15, a gear 16 is provided on the outside of the rotating rod 17, and the gear 16 is meshed with the rack 14;

[0030] The residue left by punching on the workbench 2 enters the residue collecting chamber 11 along the discharge hole 20 and gathers to the left along the slope. When a certain amount of residue accumulates in the residue collecting chamber 11 and needs to be cleaned, the rotating rod 17 is rotated to rotate the gear 16 clockwise, so that the rack 14 moves the sealing plate 13 to the right to expose the residue collecting chamber 11, and the items in the residue collecting chamber 11 can be cleaned; the materials left by punching can be automatically collected, which can make it easier to collect large residues on the device, so that it can be completely cleaned by just sucking away the dust on the workbench 2, which is more convenient.

[0031] In other embodiments, the present embodiment discloses, please Figure 1 , Figure 2 , Figure 4 As shown, one end of the rotating rod 17 passes through the fixed plate 12 and is located on the outside of the fixed plate 12 and is fixedly connected to an auxiliary rotating block 18, and anti-slip grooves are provided on the outside of the auxiliary rotating block 18. Through this design, when it is necessary to rotate the rotating rod 17, force can be better applied, and the presence of the anti-slip grooves can increase friction and avoid slipping.
