[0002] The automobile bearing cap is an important part that is applied to the rotating bearing of the automobile and has a certain support and protection function. In mechanical processing, the production and processing of the automobile bearing cap is mainly die-casting, and then it is processed by a lathe and a machining center. Finishing, because the existing die-casting process is relatively mature, and the bearing cover has a certain margin in this process, so there will be no scrap products; in the application of automobiles, the bearing cover needs to match the installation accuracy The requirements are high, which will greatly improve the requirements for finishing after die-casting. Since the surface of the semi-finished bearing cap formed by die-casting is uneven, there is no reference surface to follow, and it is not easy to clamp and fix. , which creates difficulties for other subsequent end face processing
[0003] Therefore, considering the problem of the reference plane, technicians will take the method of machining the end face of the bearing cap first, as a reference plane when machining other sides, but they consider this step, but they do not consider the actual finishing of the end face of the bearing cap. At this time, because a simple vise is used for clamping, the amount of chips on the end face is relatively large, and the upper end face and the side of the bearing cover will bear the extrusion force of the tool, so that the processed end face is inclined, and the inclined end face is used as the later stage. Machining the datum planes of other surfaces causes the overall machining accuracy to fail to meet the installation and fit requirements on the car, resulting in a large number of scrap rates

The invention relates to a clamping seat for automobile bearing cover end face processing. The clamping seat for automobile bearing cover end face processing is characterized by comprising a base and at least one group of clamping and fixing mechanisms fixedly arranged on the base through bolts, and each clamping and fixing mechanism comprises two positioning scales, a clamping device, a fool-proof device and a storage area, wherein the positioning scales are opposite bilaterally, the storage area is used for storing workpieces, and the positioning scales, the clamping device and the fool-proof device are in vertical distribution along four directions of the storage area. The clamping seat is used for processing the automobile bearing cover end faces formed by one-step five-group conjoined casting and is used for positioning and clamping by placing bearing covers needing to be processed into the storage areas, vertically positioning two sides of the bearing covers through the positioning scales, completing clamping and positioning of the two sides of the bearing covers through the clamping devices and the fool-proof devices and fixing the clamping seat on a work table of a processing center. Therefore, precise alignment processing is achieved, processing precision is guaranteed, and the processed end faces can serve as reference faces for processing other sides.
