Description
Technical Field
The utility model relates to an automobile punching press production technical field especially relates to an elastic telescopic positioning device for automobile body sheet metal component stamping die.
Background
At present, a large casting mold occupies a very large proportion in the production of automobile body sheet metal parts. In order to accurately position a raw material steel plate in a die cavity, a positioning pin made of steel is generally used, but the position of the positioning pin is fixed during production, if the position is required to be adjusted, the positioning pin can only be adjusted by professional tooling personnel such as a machine halt and the like, if the size of the raw material steel plate provided by a customer has large difference (usually, the difference is more than 2mm), the positioning adjustment amount can only be adjusted according to the maximum size of the plate, however, when the steel plate with a small size is produced, fewer edges, wrinkling and the like of a finished product are easily caused, and finally the finished product is scrapped. In order to avoid or reduce scrapping, plates with different sizes can be only adapted through frequent adjustment of professional tooling personnel. Causing great waste of personnel and efficiency and bringing great trouble to production workshops.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide an elastic telescopic positioning device for automobile body sheet metal component stamping die.
In order to solve the technical problem, the technical scheme of the utility model is that: the elastic telescopic positioning device for the stamping die of the sheet metal part of the automobile body comprises a base, wherein a U-shaped groove of the base is formed in one side edge of the base, and two base bolt through holes are formed in the other side of the base at intervals and in parallel; the positioning pin is vertical to the base and inserted into the U-shaped groove of the base, and a positioning pin bolt hole is formed in the inner side of the positioning pin; a support plate is vertically welded on the base, and a support plate bolt through hole and a support plate bolt hole are formed in the support plate; the adjusting bolt penetrates through the support plate bolt through hole to be in threaded connection with the positioning pin bolt hole, one end of the elastic jacking pin is in threaded connection with the support plate bolt hole, and the other end of the elastic jacking pin is in contact with the inner side of the positioning pin.
Further, the bottom of the base is fixedly connected with a blank holder of the stamping die through a bolt.
