Description

Technical Field

[0001] The utility model belongs to the technical field of machining tooling, and in particular relates to a machining tooling for an oil pump disassembly tool. Background Art

[0002] The oil pump disassembly tool is a disassembly tool used on the oil pump. The structure of the disassembly tool is as follows: Figure 7-9 As shown, there is a round rod-shaped tool body 3-1 in the middle, a small hexagonal head 3-2 is provided at one end of the tool body 3-1, and a large hexagonal head 3-3 is provided at the other end of the tool body 3-1. The large hexagonal head 3-3 is integrally connected with the end of the tool body 3-1 through an outer cone 3-4. In the tool, the six faces of the small hexagonal head 3-2 and the six faces of the large hexagonal head 3-3 are parallel to each other and the angle direction is consistent. Therefore, it is difficult to ensure the quality during processing. At present, there is no suitable tooling available for machining the tool. When machining the hexagonal heads at both ends on the machine tool, each corresponding two faces must be guaranteed to be parallel with a square ruler. This method is very inconvenient to operate, and it cannot well ensure the processing quality, affecting the processing efficiency. Therefore, it is necessary to propose improvements. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a machining tool for an oil pump disassembly tool. The utility model aims to design a machining tool for machining an oil pump disassembly tool to ensure that the faces of the large hexagonal head and the faces of the small hexagonal head are parallel to each other and have consistent angles and directions, thereby improving machining efficiency and ensuring machining quality.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A machining tool for an oil pump disassembly tool comprises a positioning sleeve I and a positioning sleeve II, wherein the positioning sleeve I comprises a sleeve I large diameter hole and a sleeve I small diameter hole, wherein the sleeve I small diameter hole is provided with an inner positioning cone surface for matching with an outer cone surface on the oil pump disassembly tool, and an inner thread is provided on a section of the sleeve I large diameter hole close to an outer port;

[0006] The positioning sleeve II is a T-shaped structure formed by coaxially connecting the small diameter section of sleeve II and the large diameter section of sleeve II. The outer surface of the small diameter section of sleeve II is provided with an external thread for screwing with the internal thread. The interior of the positioning sleeve II is provided with an inner hole with one end face of the small diameter section of sleeve II as an opening. A positioning groove is provided at the bottom of the inner hole. The opposite surfaces on both sides of the positioning groove are inner positioning planes parallel to each other. The two inner positioning planes are used to adapt to the two relatively parallel planes of the small hexagonal head on the oil pump disassembly tool. Two opposite and mutually parallel external positioning planes are provided on the outer surface of the large diameter section of sleeve II. The two external positioning planes are parallel to the two inner positioning planes.

[0007] As a further limitation of the above solution, the outer surface of the positioning sleeve I is a cylindrical surface and is used to fit with the spindle center hole of the indexing chuck.

[0008] As a further limitation of the above solution, two sides of one end of the positioning sleeve I are cut to form mutually parallel disassembly and assembly operation planes.

[0009] To further define the above scheme, the small diameter hole of the sleeve I also includes a small inner circular surface and a large inner circular surface, the inner positioning conical surface is arranged between the small inner circular surface and the large inner circular surface, the small inner circular surface is used to adapt to the outer circular surface of the tool body on the oil pump disassembly tool, and the large inner circular surface is used to adapt to the circular surface to be processed of the large hexagonal head on the oil pump disassembly tool.

[0010] As a further limitation of the above scheme, both the positioning sleeve I and the positioning sleeve II are made of stainless steel.

[0011] The advantages of this utility model compared with the prior art:

[0012] This scheme is aimed at the machining of the oil pump disassembly tool. In order to ensure that the six faces of the small hexagonal head on the oil pump disassembly tool and the six faces of the large hexagonal head are parallel and in the same angle direction after machining, this machining tool is designed. The positioning sleeve I is fixed in the spindle center hole of the indexing chuck. The oil pump disassembly tool is positioned by adapting the inner positioning cone surface of the small diameter hole of the sleeve I to the outer cone surface on the oil pump disassembly tool. Then, the oil pump disassembly tool is clamped by the three claws of the indexing chuck to machine the small hexagonal head of the oil pump disassembly tool. After the small hexagonal head is machined, the oil pump disassembly tool is turned upside down and the positioning sleeve is fixed. After the tube I is turned upside down, it is fixed in the main shaft center hole of the indexing chuck. The positioning sleeve II is fixed to the rear end of the positioning sleeve I by rotating the internal and external threads coaxially. The small hexagonal head processed by the oil pump disassembly tool is inserted into the positioning sleeve I and the positioning sleeve II and inserted into the positioning groove in the positioning sleeve II. It is positioned and processed through the two inner positioning planes in the positioning groove. Then, through the parallel relationship between the two inner positioning planes and the two outer positioning planes combined with the indexing function of the indexing chuck, the large hexagonal head is processed to ensure that the large hexagonal head and the small hexagonal head are parallel to each other and the angle direction is consistent. This tooling improves the processing efficiency and ensures the processing quality. BRIEF DESCRIPTION OF THE DRAWINGS
