The invention relates to a concentricity detection jig for a safety belt frame of an automobile. The safety belt frame of the automobile comprises a first side plate and a second side plate arranged in parallel, and a first connecting joint is arranged on the first side plate and the second side plate. hole and the second connection hole, a plurality of positioning holes are also provided on the first side plate and the second side plate respectively, the concentricity detection jig includes a base, stands on the base and passes through the first connection hole and the second connection hole respectively The mandrel of the hole, the positioning pins that are arranged on the base to match with a plurality of positioning holes, and the detection module that can be sleeved on the upper part of the mandrel from the center, the shape of the detection module is consistent with the first connection hole or the second connection hole The shapes are similar and can be inserted into the first connection hole or the second connection hole. The detection method of the invention is very convenient and has selectivity. At the same time, the invention has a simple structure and can effectively control the qualification rate of products.
Description
Technical field [0001] The invention relates to a concentricity detection fixture for an automobile safety belt frame. Background technique [0002] The car seat belt frame generally includes side panels on both sides and connecting panels for connecting the side panels on both sides. The side panels on both sides are provided with connecting holes, and most of the connecting holes are irregular holes. , But if the centers of the connecting holes on both sides are not in the same straight line, then the car seat belt frame will be sideways after connecting with other parts, which may not be able to realize the normal use of the car seat belt, and, once the two side panels appear If the center of the connecting hole is not on the same straight line, it will affect the subsequent installation of other components, and the loss caused is beyond estimation. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of ...
