Description

Piston insert clamping jaw Technical Field The utility model relates to the technical field of instrument processing, in particular to a piston insert clamping jaw. Background Along with the improvement of engine power, supercharging load, reciprocating high speed and other parameters, the requirements on the performances of strength, high temperature resistance, impact resistance, wear resistance and the like of the engine core component piston are higher and higher, the aluminum-silicon series piston mainly adopts a wear-resistant insert ring and an internal cooling oil duct structure, and the purpose of the piston adopting the insert ring structure is to improve the wear resistance of an aluminum piston-ring groove and prolong the service life of the piston. However, in order to avoid unsmooth heat transfer between the wear-resistant insert ring and the aluminum body, the combination requirement of the wear-resistant insert ring and the piston body is quite high, and the existence of the hole-shaped defect is not allowed. In order to meet the bonding quality requirement of the wear-resistant insert and the aluminum body, the insert needs to be subjected to aluminizing operation in the production process, and the aluminized layer needs to be prevented from being cooled or damaged in the transfer process of the insert after aluminizing, so that the defect of poor bonding of the insert is caused. In the actual operation process, as shown in fig. 3, the aluminized insert is transferred through the clamping jaw and is installed in the die, a small-area aluminized layer is damaged on the surface of the insert, and hole defects can be formed at the edge position of the insert after the piston blank cast by the insert is processed. Disclosure of utility model In order to solve the problems, the utility model provides a piston insert clamping jaw which comprises an insert clamping jaw, a pneumatic claw disc, a clamping base and a plurality of L-shaped insert positioning rods, wherein the insert clamping jaw is fixedly arranged on the pneumatic claw disc through nuts, the pneumatic claw disc is embedded into the lower end of the clamping base through mortise and tenon joints, and the L-shaped insert positioning rods are arranged on the clamping base in an embedded mode. The clamping jaw of the insert ring is characterized by further comprising an L-shaped supporting seat and an L-shaped clamping piece, wherein one end of the L-shaped supporting seat is fixedly arranged on the pneumatic claw disc through a nut, and the other end of the L-shaped supporting seat is fixedly connected with the L-shaped clamping piece through a nut. Further, the bottom end of the clamping jaw is lower than the bottom end of the L-shaped insert positioning rod. Further, the number of the L-shaped insert positioning rods is specifically 2, and the L-shaped insert positioning rods are respectively arranged on two sides of any clamping jaw of the insert clamping jaw. Further, the insert clamping jaw, the pneumatic claw disc, the L-shaped insert positioning rod and the clamping base are all made of stainless steel. The utility model provides a piston insert clamping jaw, which has the following beneficial effects: The clamping and flattening functions are separated, the damage degree of an aluminized layer on the surface of the insert ring is reduced, the probability of generating defects of slag holes on the edge of the ring is reduced, and the grasping reliability of the insert ring is improved.
