Description

A kind of for the production of universal joint from aligning elasticity lathe tool
Technical field
The utility model relates to auto parts production equipment field, particularly a kind of for the production of universal joint from aligning elasticity lathe tool.
Background technology
Constant velocity cardan joint occupies the critical role of automobile driving axle industry with the constant angular velocity moment transmission of its uniqueness and superior mechanical performance, and constant velocity cardan joint processing and manufacturing quality is related to serviceability and the life-span of product especially.Existing constant velocity cardan joint manufacturing process is greatly improved, but adds man-hour carrying out cup external diameter lathe finish, main or adopt the technical scheme of regular stationary tool locating clamping, has carried out the fine finishining of universal joint cup external diameter.
The fixed tool locating scheme that the fine finishining of existing constant velocity cardan joint cup external diameter adopts, mainly puts the conic clamp that product cup end face leans against fixed frock and positions, with product cup end face for benchmark carries out the processing of every size.The program can meet the location requirement of universal joint finish turning processing under certain condition, but also there is technological deficiency, there is certain dimensional tolerance in the product cup external diameter after roughing, the degree of depth of overlapping contact point after the product clamping that cup outside dimension is bigger than normal and less than normal with conic clamp is inconsistent, namely the cup outside dimension precision after product coarse processing can affect the axial dipole field of Set and Positioning, and the size of side-play amount directly causes the product cup high accuracy of processing for benchmark finish-milling with cup end face; In addition, product cup end face and the single contact Set and Positioning of taper cutting ferrule, exist because the factors such as taper cutting ferrule wearing and tearing cause product clamping coaxiality error and have influence on the risk of processing precision of products.
Summary of the invention
The object that the utility model will reach be to provide a kind of for the production of universal joint from aligning elasticity lathe tool, automatically can regulate the position with the contact surface of product cup, thus eliminate the fine finishining loss of significance brought because of roughing precision, frock wear intensity.
