Positioning tool for machining eccentric flange covers and application method thereof

Abstract

The invention discloses a positioning tool for machining eccentric flange covers. The positioning tool comprises a positioning base and a positioning fixture; the positioning base is provided with aneccentric positioning groove; the eccentric distance between the circle center of the eccentric positioning groove and the circle center of the positioning base is e; and the flange covers are clampedin the eccentric positioning groove, and are fixed through the positioning fixture. A circular eccentric groove is formed in the top surface of the flange cover; and the distance between the circle center of the circular eccentric groove and the center of the flange cover is equal to the eccentric distance e. When the positioning tool is used for machining the eccentric flange covers, the flangecovers only need to be mounted on the positioning tool; the positioning tool is provided with the eccentric positioning groove eccentrically structured; the flange covers cooperate with the eccentricstructure on the positioning tool; the flange covers are deflected on the positioning tool without adjusting a fixture and a cutter of the machine; the eccentric flange covers meeting requirements canbe machined by using a conventional machining method; the machining precision is high; and the product pass percent is high. The invention further discloses an application method of the positioning tool.

Description

technical field [0001] The invention belongs to the technical field of motor parts processing, and in particular relates to a positioning tool for processing eccentric flange covers and a use method thereof. Background technique [0002] With the development of technology and the improvement of product function and precision requirements, some non-standard parts came into being. The eccentric flange structure fundamentally changed the sealing structure, no longer a position seal, but a torsion seal. The eccentric flange and It has the advantages of good sealing, easy operation, less maintenance, good self-cleaning ability, etc., and is widely used in the mechanical field. However, the processing of eccentric flanges is still a technical problem. Due to eccentricity, when using machines for processing, it is necessary to continuously adjust the position of the tool, or to make the fixture eccentric. Generally, the fixtures on the machine are centered. Adjusting the position ...

AI Technical Summary

Problems solved by technology

However, the processing of eccentric flanges is still a technical problem. Due to eccentricity, when using machines for processing, it is necessary to continuously adjust the position of the tool, or to make the fixture eccentric. Generally, the fixtures on the machine are centered. Adjusting the position of the fixture to make it eccentric when the flange is covered will not only cause errors during adjustment, but also cause damage to the machine due to the eccentric rotation of the fixture, and if the machine is used to process other parts, the fixture needs to be adjusted again. The operation is cumbersome and complicated, and it will also cause the machine to be inaccurate, so that the processed products have large errors and the qualified rate of finished products is low
