Automobile B-pillar positioning and clamping mechanism

Abstract

The invention discloses a car B-pillar locating clamping mechanism which comprises a fixing support. A left guiding way, a right guiding way and a middle guiding way are arranged on the front side of the fixing support. A pushing base penetrates into the left guiding way and the right guiding way. A connecting head is fixedly connected to the middle portion of the pushing base. The back end of the connecting head is connected with a pushing air cylinder. The front end of the connecting head is connected with a connecting box. The top of the front end of the connecting head is provided with a pin shaft. A pin shaft sliding hole is formed in the top of the connecting box. The front end of the connecting head extends into the connecting box, the pin shaft penetrates out from the pin shaft sliding hole, the front end of the connecting box is fixedly connected with a B-pillar Y-direction locating block, and a compressed spring is arranged between the connecting box and the fixing support. Pushing supports are fixedly connected to the left end and the right end of the front side of the pushing base symmetrically and are connected with rotating arms which are connected with B-pillar clamping blocks and B-pillar X-direction locating blocks. Guiding holes are formed in the middle of the rotating arms and are hinged to the pushing supports. The tail ends of the rotating arms are placed at the front end of the pushing base and are hinged to the fixing support. According to the mechanism, the air cylinder drives a plurality of locating structures to move in a sub-step mode, and B pillars of different cars can be located and clamped.

Description

technical field [0001] The invention relates to automobile production equipment, in particular to an automobile B-pillar positioning and clamping mechanism. Background technique [0002] At present, each station of the automobile side wall production line is arranged in a flat manner. It is difficult to share fixtures for the side walls of different models. Usually, it is necessary to design the production line stations separately or switch the fixtures as a whole for the side walls of different models, which leads to the production line. Large and large investment in equipment and other issues. In order to avoid the above problems, when considering the vertical placement of the side wall, the Z-direction common positioning will be set under the threshold when the side wall is pre-installed. At this time, how to realize the X-direction and Y-direction positioning clips of the B-pillar part of the side wall Tight, and how to make this positioning and clamping method applicab...
