Technical Field
The utility model belongs to the technical field of bell shell processing and specifically relates to a bell shell finish turning clamping frock is related to.
Background
The outer bell is a part of a constant velocity universal joint transmission shaft assembly, which is a connecting driving device between a gear box and a tire hub and belongs to an automobile chassis system. The purpose is that the power torque generated by the engine is transmitted to the tire for running after passing through the gearbox.
With the increasing requirements of users on the operating performance of automobiles, the constant velocity universal joint drive shaft assembly is one of the main safety parts of the automobiles and needs to be improved inevitably. In the constant velocity universal joint drive shaft assembly, for example, the jitter of the three-column groove shell, the intermediate shaft and the bell shell is too large, which causes the jitter and abnormal sound of the constant velocity universal joint drive shaft assembly.
The common bell car profile is now (see fig. 4): and clamping the excircle and then pushing the rotating centre against the central hole of the rod part by taking the large end surface of the opening part as a reference. The clamping workpiece with the structure can generate an over-positioning condition, one end of a product close to the rotating center jumps greatly by 0.15-0.40mm in processing, and the jumping is different, so that the requirement of the constant velocity universal joint transmission shaft assembly on each part can not be met after the parts are processed, and the shaking and abnormal sound probability of the constant velocity universal joint transmission shaft assembly is also greatly improved.
Chinese patent 'CN 103212731A' is a constant velocity joint bell shell internal stay anchor clamps, and this patent can accomplish the rough and finish turning to bell shell external diameter and terminal surface simultaneously, gets rid of secondary clamping error risk and reduces the time consumption of dismantling the clamping work piece, has the advantage that the product precision is high, intensity of labour is little, production efficiency is high. However, when the inner support fixture tightly supports the bell-shaped shell, the main fixture body on the inner support fixture body is not coaxial with the bell-shaped shell, so that the outer diameter and the end surface of the bell-shaped shell cannot be processed smoothly when the inner support fixture is installed on a lathe, and the structure of the whole inner support fixture is complex.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a bell housing finish turning clamping frock, the solution is with the product one end that is close to the live center beat very big man-hour, such parts machining can't satisfy the problem of the requirement of constant velocity universal joint transmission shaft assembly to each part after coming out.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a finish turning and clamping tool for an outer shell comprises a clamp body, wherein an inner pulling block is arranged at one end of the clamp body, an inner pulling rod is arranged, the inner pulling rod penetrates through the clamp body to be connected with a pulling-out mechanism, and a conical surface matched with the inner pulling block is arranged on the inner pulling rod.
In the preferred scheme, the inner pulling blocks are multiple and are arranged along the uniform circumference of the clamp body.
In the preferred scheme, the end part of the inner pulling block is provided with a groove, an extension spring is arranged in the groove, and the extension spring surrounds the inner pulling blocks to form a circle.
