Embodiment Construction

[0018] Such as figure 2 Shown: a P-type pump plunger snap ring disassembly tool, which is composed of a core rod 5 and an elastic sleeve 6, the core rod 5 is cylindrical, and its lower end has a conical round table 51 and a top 52, and an elastic sleeve 6 is installed It is a hollow tube, its upper end is a guide sleeve 61, and its lower end is an elastic sleeve 62. There is a longitudinal long groove 63 on the elastic sleeve 62, and the wall thickness of the guide sleeve is greater than that of the elastic sleeve.

[0019] Using method and operation process of the present invention are:

[0020] When needing to disassemble the automobile P type pump plunger snap ring, the present invention is put into the pump body 1 deep hole, withstood the plunger 2 with the top 52 of stamen rod 5 and makes it move downwards (as image 3 shown), and the snap ring 4 on the plunger 2 is blocked by the spring pad 3 in the deep hole of the pump body 1, and is separated from the plunger 2 and ...

Abstract

A tool for disassembling plunger snap rings of P-type pumps for automobiles. It consists of a core rod 5 and an elastic sleeve 6. The core rod 5 is cylindrical, and its lower end has a conical round table 51 and a plug 52. The elastic sleeve 6 is a hollow circle. Pipe, its upper end is a guide sleeve 61, the lower end is an elastic sleeve 62, and the elastic sleeve 62 has a longitudinal long groove 63, and the wall thickness of the guide sleeve is greater than that of the elastic sleeve. Due to the adoption of the above design, the present invention does not damage the precise working surface and deep hole of the plunger compared with the traditional manual disassembly and assembly, and has the advantages of flexible use, simple operation, low labor intensity, and high disassembly and assembly efficiency.

Description

technical field [0001] The invention relates to a special deep-hole snap ring disassembly tool, in particular to a P-type pump plunger snap ring disassembly tool. Background technique [0002] At present, in the prior art, there is no deep hole snap ring dismounting tool for manual operation. There is a plunger 2 and a spring pad 3 in the deep hole of the pump body 1 of the automobile P-type pump, and there is a snap ring 4 on the plunger 2 (such as figure 1 shown). The existing mode of disassembling snap ring 4 in pump body 1 deep hole is: adopt conventional tools such as screwdriver, pliers to manually disassemble snap ring 4 in pump body 1 deep hole. Because there is not much space for disassembling snap ring 4 in the deep hole of pump body 1, it is quite difficult to disassemble snap ring 4, and it is also afraid of damaging the precision working surface of plunger 2 and the inner wall of pump body 1 deep hole, which is inconvenient and wasteful. time.
