Finish-milling clamp suitable for top surface of inclined cylinder head

Abstract

The invention discloses a finish-milling clamp suitable for the top surface of an inclined cylinder head. The finish-milling clamp comprises a base arranged on a cylinder head and a hold-down mechanism arranged on the base and used for fixing the cylinder head, wherein the base comprises an obliquely arranged positioning plate; the cylinder head is positioned by a positioning mechanism of which the bottom surface is placed on the positioning plate; and an inclined plane with the same inclined angle as the top surface of the cylinder head is formed on the positioning mechanism. Compared with the prior art, as the mounting and placing position of the cylinder head are consistent with the angle of the top surface of the cylinder head, after the cylinder head is clamped, processing of a machine tool cutter in the horizontal direction can be kept, accordingly, the problem of complicated angular adjustment in a traditional tool is greatly solved, conveniences are brought to a worker to operate and clamp, and the clamping efficiency of the cylinder head is remarkably improved; and the finish-milling clamp has the advantages of high clamping precision, simple structure and convenience in operation, and staff for processing the product can start to work without training.

Description

technical field [0001] The invention relates to a jig, in particular to a top surface finish milling jig suitable for an engine cylinder head with a slope. Background technique [0002] At present, in the machining process of the cylinder head of the automobile engine, the fine milling of the top surface of the cylinder head is a very important process in the process, and its machining accuracy will directly affect the product quality of the engine cylinder head, especially when the engine cylinder head It is more difficult to process when the top surface has a certain angle, such as cylinder head Figure 5 shown. Since the top surface of the engine cylinder head is inclined, the finishing process of the top surface is very difficult, the main part of which is the problem of tooling. In the general processing process, the cylinder head is often placed in the traditional long machine tool in the machine tool during clamping. On the slats, and carefully adjust the processing ...

AI Technical Summary

Problems solved by technology

Using this clamping method requires the operator to have very skilled technology, and since the top surface of the automobile engine cylinder head is inclined, in order to ensure that the cylinder head can still be processed in the horizontal direction of the machine tools after clamping, the operator It often takes a long time to adjust the machining angle during the machining process, which has an unnecessary impact on the machining efficiency of the cylinder head, and the large reference plane of the long slab causes the problem that the plane of the positioning surface is too large, so that A large system deviation is generated, and the yield of the processed cylinder head will decrease at this time
