Problems solved by technology

[0002] Large-scale parts, especially large-scale castings after casting, need to be finished after casting to meet the functional and connectivity requirements of large-scale castings, but especially for many curved surfaces, the surface shape is relatively For complex large-scale castings, 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 the processing of each surface and each part must be fixed separately, so that its processing The construction period is long, which wastes manpower. During processing, there will be a phenomenon of tool vibration, which will affect the local dimensional accuracy of the large castings to be processed, and even cause scrapping, and the positioning accuracy is not good.
And each positioning may require different fixtures, and the cost is relatively high

Abstract

The invention discloses a multi-hole, multi-plane and same-direction finish machining fixture for large castings. The fixture comprises multiple L-shaped brackets connected in parallel, wherein the horizontal parts of all the L-shaped brackets are connected, and are provided with upward horizontal support projections; the vertical parts of all the L-shaped brackets are backwards projected to form vertical reinforcing ribs; multiple lower and upper support bases are respectively arranged on the horizontal projections of the L-shaped brackets and the vertical reinforcing ribs near the top positions; each lower support base is connected with parts to be machined through a net-shaped bracket; each upper support base is connected with the parts to be machined through a clamping device; at least one clamping device is connected with a single linkage clamping mechanism; and each single linkage clamping mechanism comprises chains for tensioning and transmission. The fixture is accurate in positioning, improves the workpiece machined surface smoothness, the machining size precision and the automation degree, and shortens the machining period.

Description

technical field [0001] The invention relates to the technical field of large-scale component finishing, in particular to a fixture for large-scale casting porous multi-plane finishing with the same orientation. Background technique [0002] Large-scale parts, especially large-scale castings after casting, need to be finished after casting to meet the functional and connectivity requirements of large-scale castings, but especially for many curved surfaces, the surface shape is relatively For complex large-scale castings, 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 the processing of each surface and each part must be fixed separately, so that its processing The construction period is long, which wastes manpower. During processing, there will be a phenomenon of tool vibration, which will affect the local dimensional accuracy of the large castings to be proces...
