Abstract

The invention discloses an elastic telescopic positioning device for an automobile body sheet metal part stamping die. The elastic telescopic positioning device comprises a base, a base U-shaped groove is formed in the edge of one side of the base, and two base bolt through holes are formed in the other side of the base at intervals in parallel; a positioning pin is perpendicular to the base and is inserted into the base U-shaped groove, and a positioning pin bolt hole is formed in the inner side of the positioning pin; a supporting plate is vertically welded to the base, and a supporting plate bolt through hole and a supporting plate bolt hole are formed in the supporting plate; and an adjusting bolt penetrates through the supporting plate bolt through hole to be in threaded connection with the positioning pin bolt hole, one end of an elastic lifting pin is in threaded connection with the supporting plate bolt hole, and the other end of the elastic lifting pin is in contact with the inner side of the positioning pin. The adjusting amount of the positioning pin can be changed by applying pressure to the positioning pin and the elastic lifting pin through the weight of a raw material steel plate, the positioning pin can be adjusted without shutdown when the sizes of the raw material steel plate are greatly different, then the production efficiency is guaranteed, and labor-hour waste of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile stamping production, in particular to an elastic telescopic positioning device for stamping dies of automobile body sheet metal parts. Background technique [0002] At present, large-scale casting molds occupy a very large proportion in the production of automobile body sheet metal parts. In order to accurately locate the raw material steel plate in the mold cavity, a positioning pin made of steel is generally used, but the position of this positioning pin is fixed during production. If you want to adjust the position, you can only stop it and wait for professional tooling personnel to adjust it. If When there is a large difference in the size of the raw material steel plate provided by the customer (usually the difference exceeds 2mm), the positioning adjustment can only be adjusted according to the maximum plate size. Wrinkles, etc., eventually led to the scrapping of finished parts. In ord...
