Description
Technical Field
The utility model relates to a hydraulic torque converter's manufacturing and processing technology field, concretely relates to hydraulic torque converter lid assembly lathe work anchor clamps's elasticity auxiliary stay structure.
Background
With the acceleration of the localization process of the automatic transmission of the automobile, the torque converter of the automobile applied to AT and CVT is increasingly emphasized, but the manufacturing process of the torque converter is complex, the manufacturing difficulty is high, the early investment is large, the profit is low, the experience of processing the product by using general equipment is insufficient, and the technical difficulty is high. With the processing of global market competition and fierce degree, the development and application of the automobile hydraulic torque converter in China are gradually reduced, and the development and manufacturing of the hydraulic torque converter by using the existing general equipment under the existing conditions play an extremely important role in promoting the development of the automobile industry and the hydraulic transmission industry in China.
The hydraulic torque converter consists of a cover assembly, a turbine assembly, a pump wheel assembly, a pressure plate assembly and a guide wheel assembly. The cover assembly is formed by welding a cover blank formed by punching a plate with the material thickness of 4.5mm, a fixed block and a positioning column and then machining to obtain a final product with the maximum outer diameter phi of 250 mm. The machining precision requirement is high, the machining clamping deformation of the thin-wall part is large, the number of supporting points is small, the deformation caused by cutting force is difficult to control, and the machining difficulty is large. Especially the problem of vibration lines on the friction surface of the cover assembly is prominent.
The existing turning clamp for the friction surface of the cover assembly mainly comprises a clamp body, an excircle auxiliary clamping mechanism, a radial positioning clamping mechanism, a positioning column, an axial positioning supporting mechanism and the like. When clamping, a workpiece is firstly placed into a jacket of the radial positioning clamping mechanism, meanwhile, the end face of the fixing block of the cover assembly is attached to the positioning face of the axial positioning supporting mechanism, and the axial movement of the hydraulic cylinder of the device pulls the radial positioning clamping mechanism to move axially, so that the positioning and clamping of the cover assembly are completed. The lathe main shaft drives the frock rotatory, and outer circle auxiliary clamping mechanism radially embraces the part excircle under the centrifugal force effect, in the course of working, provides reliable clamping force, prevents that the part from skidding, reduces the partial processing deformation of excircle. The main disadvantages of the tool are that: when the friction surface of the cover assembly is machined, the axial supporting parts of the parts are uniformly distributed on a ring surface with the diameter of phi 217-phi 257 in total at 3 positions, and the width of each supporting part is 20. The supporting surface is too small, the machining surface is relatively large, the rigidity provided by the end surface supporting point is insufficient, vibration lines are generated on the machining surface due to vibration in the machining process of parts, and the roughness of the machining surface cannot meet the technological requirement.
In order to meet the processing requirements, the method of reducing the rotating speed and the feeding amount to avoid vibration in the processing process seriously reduces the cutting efficiency and is not suitable for large-scale processing.
