Abstract

The invention belongs to the technical field of machining, and particularly relates to a non-revolution body part lathe clamp which is used for assisting a non-revolution body part to realize the lathe rotary cutting function in the non-revolution body part cutting machining process. The non-revolving body part lathe clamp comprises a clamp base body, the left end of the clamp base body is of a cylindrical structure, the right end of the clamp base body is a mounting end, a through hole is formed in the mounting end, a fixed bolt penetrates through the through hole, the part is located on themounting end, a pressing plate is arranged above the part, a tightening nut and a fixing nut are arranged on the fixing bolt respectively, the axis of the machining center of the part coincides with the axis of the outer circle of the cylindrical structure, and the rotary cutting function is realized. According to the non-revolution body part lathe clamp, the reunion of the machining axis of the non-revolution body part and the axis of the main shaft of the machine tool is realized, so that the machining precision of the part can be effectively guaranteed, the weight of the clamp is reduced compared with that of a traditional splicing clamp, so that the phenomenon of machine tool vibration caused by unbalanced weight is avoided, and the processing precision is ensured.

Description

technical field [0001] The application belongs to the technical field of mechanical processing, and specifically relates to a non-rotating body part lathe fixture used to assist the non-rotating body part to realize the turning cutting function of the lathe during the cutting process of the non-rotating body part. Background technique [0002] At present, there are many non-rotating parts in aircraft hydraulic and structural systems, such as Y-shaped fork lug parts and support parts, which need to process outer circles or inner holes, and have high dimensional accuracy requirements during the processing. [0003] The traditional processing method is to use an assembled fixture so that the axis of the outer circle or inner hole of the part to be processed coincides with the axis of the machine tool spindle, so as to realize the rotary cutting processing of non-rotating parts. [0004] Existing related patents have the patent number CN200810243705.0, the application date is 20...
