Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0017] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention is composed of a riveting gun cylinder 1, a positioning cylinder 2, a pull pipe 3, a push rod 4 and an adjusting disc 5, wherein the riveting gun cylinder 1 is a prior art, and its structure will not be repeated here. On the left side of the riveting gun cylinder 1 cylinder 1a as shown in the figure, a positioning cylinder 2 is provided. The positioning cylinder 2 is a straight-through pipe structure. The left end of the central hole of the positioning cylinder 2 expands into a circular accommodation groove 2a, and the right end of the positioning cylinder 2 is integrated. A threaded head 2b with a slightly smaller diameter is formed, and the threaded head 2b extends into the cylinder body 1a of the riveting gun cylinder 1, and the two are screwed together. The ce...

Abstract

The invention discloses a bearing dismounting tool which is characterized in that: a positioning cylinder is fixed on the cylinder body of a hand riveter cylinder, the cylinder shaft of the hand riveter cylinder extends to the positioning cylinder to be fixed with one end of a pull tube, the other end of the pull tube extends out of the positioning cylinder, the tube wall of the pull tube out of the positioning cylinder is provided with 3-8 openings along axial direction and in even circumferential distribution, and the center hole of the pull tube at the end has conical closing-in structure; a mandrel penetrates through the cylinder shaft of the hand riveter cylinder and extends to the pull tube to be in threaded fit with the pull tube, the conical end of the mandrel extends to the pull tube and is matched with the closing-in structure at the center hole end part of the pull tube in shape and size. The bearing dismounting tool has simple structure, easy assembly, low cost, light weight, overcomes site limits, not only has convenient and reliable operation and movement, but also has strong generality, can effectively improve the bearing dismounting efficiency and greatly reduces the labor intensity for operators.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to a drawing tool with built-in bearings. Background technique [0002] At present, when the engine is being repaired or a small batch of trial assembly of the engine is wrong, the bearing in the crankcase needs to be disassembled. The usual way is to use special tooling and use the cylinder to push the bearing out. The existing claw-type tooling has a complex structure and high cost. On the one hand, it is relatively heavy and limited by the site; on the other hand, it is inconvenient to operate and move, has poor versatility, low efficiency, and high labor intensity for operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bearing removal tool with simple structure and convenient operation. [0004] The technical scheme of the present invention is as follows: a bearing removal tool, comprising a r...
