Fixtures for the mounting plane of the main reducer shell of a passenger car and the joint surface of the tile cover

Abstract

The invention belongs to the field of vertical machining devices of a main reducing gear housing of a passenger car, and particularly relates to a work fixture for an installation plane and a tile lid combination face of the main reducing gear housing of the passenger car. The work fixture comprises a bottom board, an angular locating device, five or more auxiliary supporting and compressing devices and a main compressing device, wherein the angular locating device, the auxiliary supporting and compressing devices and the main compressing device are fixedly arranged on the bottom board. The auxiliary supporting and compressing devices are distributed in the circumferential direction. The main compressing device is arranged in the circumferential line where the auxiliary supporting and compressing devices are distributed. The angular locating device is arranged outside the circumferential line where the auxiliary supporting and compressing devices are distributed. The work fixture is simple in structure and high in machining accuracy, and main reducing gear housings of various types can be machined under the situation of replacing a locating block of the angular locating device.

Description

technical field [0001] The invention belongs to the field of vertical processing devices for main reducer shells of passenger cars, and in particular relates to a tooling fixture for the installation plane and tile joint surface of the main reducer shell of passenger cars. Background technique [0002] With the vigorous development of processing technology in my country's processing and manufacturing industry, some advanced technologies and products from abroad have been introduced and applied continuously, and the processing and manufacturing technology of the main reducer housing of related passenger cars in China has also been continuously improved and improved. At present, the vertical machining center has been widely used in the domestic bus main reducer shell processing and manufacturing industry; but the corresponding high-efficiency, high-precision, and high-accuracy tooling for manufacturing the It is too late to keep up with the pace of development. The structure a...

Problems solved by technology

[0003] However, there are deficiencies in the above two tooling types

The first type of tooling clamping method has many human factors involved, relying on people to ensure the consistency of clamping, unstable factors exist at any time, and the production efficiency has a lot to do with the proficiency of personal operation; although it can meet the processing requirements of various products , but the consistency of product accuracy is poor, and because of the variety of main reducer housings for passenger cars, frequent production changes have seriously restricted the increase in workshop production output

[0004] The second method of tooling avoids frequent replacement, but it is difficult to meet the different requirements of different processes and different types of parts for tooling, and it is difficult to guarantee the processing accuracy of products continuously and stably.
