Fixtures for finishing the mounting part of large bearing housing castings

Abstract

The invention relates to the technical field of finish machining of large casting, in particular to a clamp for finish machining of a large bearing seat casting installation portion. The clamp comprises a bottom plate, a plurality of vertically-arranged supporting plates are arranged on the bottom plate, the supporting plates are arranged in the radial direction of a circle, and the diameter of the circle is less than the bore diameter of a bearing bore of a bearing seat to be machined. Pressing plates are arranged on the upper parts of the supporting plates, the direction of the plate lengthof the pressing plates is the radial direction of the circle, strip-type through holes penetrating through plate faces are formed in the pressing plates, and screws pass through the strip-type throughholes and the pressing plates are fixed to the tops of the supporting plates through nuts. The multiple supporting plates which are arranged in the radial direction of the circle pass through the bearing hole of the bearing seat, the clamp is pressed and fixed to the bottom plate, the clamping of the bearing seat to be machined is realized, the standard of each clamp is on a separate surface, once the clamp is machined, the corresponding fixed position cannot be changed, the stability of clamping positioning of bearing seat to be machined in batch production is improved, and the machining accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of finishing of large castings, in particular to a fixture for finishing the installation part of a large bearing seat casting. Background technique [0002] In the prior art, for large-scale castings with irregular and complex surface shapes, in the finishing process, whether it is positioning or processing after positioning, the operation requires the cooperation of multiple people at the same time, and each surface and each Partial processing must be fixed separately, which makes the processing period longer and wastes manpower. During processing, the phenomenon of knife vibration will also occur, which will affect the local dimensional accuracy of the large castings to be processed, and even cause scrapping in serious cases. Contents of the invention [0003] In view of the problems in the prior art, the object of the present invention is to provide a fixture for finishing the mounting part of a large-...
