[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0012] like Figure 1-3 A provincial commercial vehicle drive axle housing processing pipa hole positioning tool, including a workbench 1, the middle of the workbench 1 is fixed with the cylinder end of the vertical oil cylinder 11, both ends of the workbench 1 are fixed with a group of rails 2, each group of rails 2 is provided with a slider 5, and the slider 5 can slide on the rail 2.

[0013] The slide block 5 is fixed with a cylinder clamp 3 , and two free ends of the cylinder clamp 3 are respectively fixed with a clamping head 4 . The clamping head 4 can move horizontally and is used to clamp the workpiece in the radial direction.

[0014] A vertical sleeve 14 is fixed in the middle of the workbench 1, and the piston end of the vertical cylinder 11 is fixed to the vertical shaft 12. The vertical shaft 12 is located in the sleeve 14 and can slide therein. The upper end of the vertical shaft 12 is a conical surface 13, and a through hole 16 is symmetrically provided at the upper end of the sleeve 14. Each through hole 16 can be passed through a push rod 6. The outer end of the push rod 6 is a plug 61, and the outer end of the push rod 6 is a slope 62.

[0015] In order to facilitate centering, the push rod 6 and the through hole 16 are clearance-fitted.

[0016] The workbench 1 is formed by welding steel materials and then fine-processing.

[0017] Its working principle is:

[0018] S1. Preparation: Estimate the half-axle length of the commercial vehicle drive axle housing 90 (hereinafter referred to as the workpiece), slide the slider 5 to the appropriate position, open the cylinder clamp 3, position the two clamping heads 4 on the far side, retract the piston end of the vertical cylinder 11, and position the push rod 6 on the inside.

[0019] S2. The robot clamps the workpiece so that its pipa hole is located above the vertical axis 12.

[0020] S3. The piston end of the vertical oil cylinder 11 extends, and the upper end of the vertical shaft 12 moves upward, and through the cooperation between the conical surface 13 and the inclined surface 62, the two push rods 6 are pressed to extend outward.

[0021] S4. When the top 61 of the push rod 6 reaches the inner wall of the pipa hole, the axle is axially centered and no longer moves, and the axle is aligned.

[0022] S5. The cylinder clamp 3 contracts, and the two clamping heads 4 hold the ends of the axle tightly. The axle is fixed radially and no longer moves / rotates, and the positioning and clamping is completed.

[0023] The technical effects of the utility model are as follows: the utility model is provided with the cooperation of the conical surface and the inclined surface and two symmetrical ejector rods, which are easy to align; and the workpiece can be conveniently fixed by the clamp.

[0024] For other contents, please refer to the prior art.

[0025] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
