Description

Screw spin riveting positioning device Technical Field The utility model relates to the technical field of spin riveting, in particular to a screw spin riveting positioning device. Background The spin riveting equipment is a mechanical device which is developed according to the cold rolling principle and uses rivets to rivet articles. The device is assembled mainly by rotation and pressure, and is widely applied to various occasions needing rivet riveting. The prior Chinese patent publication No. CN209614008U discloses a screw spin riveting positioning device, which comprises a fixed seat, a screw positioning piece, a biasing piece and a biasing piece, wherein the fixed seat is suitable for being arranged on a shell, a first mounting groove for accommodating a screw is formed in the edge position of the fixed seat, the screw positioning piece is rotatably arranged on the fixed seat and is provided with a turning arm part far away from the edge of the fixed seat, a positioning part which is formed at the end part of the turning arm part and is matched with a screw through hole, and the biasing piece is used for applying a biasing force for rotating towards the screw direction to the turning arm part. According to the screw spin riveting positioning device provided by the utility model, the screw positioning piece is rotatably arranged on the fixed seat and is provided with the turning arm part far away from the edge of the fixed seat and the positioning part which is formed at the end part of the turning arm part and is matched with the screw through hole, so that most of the edge thickness of the positioning seat can be thicker and is not easy to break, and the service life of the screw spin riveting positioning device is prolonged. However, in the actual use process of the device, a plurality of dovetail grooves are required to be formed in the fixing seat, and meanwhile, parts such as a crank arm part and the like are required to be mounted on the fixing seat, so that the manufacturing difficulty is high. Disclosure of Invention The utility model solves the technical problem of overcoming the defects of the prior art and providing a screw spin riveting positioning device. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a screw rivets positioner soon, includes the fixing base, the right side of fixing base is seted up flutedly, the inner chamber activity grafting of recess has the screw installation piece, the left side fixedly connected with fixed strip of screw installation piece, the front side fixedly connected with spacing of screw installation piece, the dovetail has been seted up in the inner chamber left side of recess, the spacing has been seted up to the inner chamber front side of recess, the perforation has been seted up on the screw installation piece, the top of screw installation piece is equipped with the ring, the equal fixedly connected with gag lever post in front side and the left side of ring, two spacing holes have been seted up at the top of fixing base, the inner chamber activity grafting of ring has the screw. Preferably, the cross section of the fixing strip is isosceles trapezoid, and the fixing strip is movably inserted into the inner cavity of the dovetail groove. Preferably, the limit bar is movably inserted into the inner cavity of the limit groove, and the limit bar is mutually matched with the limit groove. Preferably, the cross section of the limiting rod is L-shaped, and the limiting rod is movably inserted into the inner cavity of the adjacent limiting hole.
