The technical scheme of the invention is as follows: this kind of friction weld steel claw is with centering fixture, it includes: the steel claw sandwich structure comprises a clamp body (1), a steel claw sandwich (3), a pull rod (6) and a steel claw (7);
before friction welding, the steel claw (7) is placed in the inner hole of the clamp body (1), the right side wall of the steel claw sandwich core (3) and the inner hole of the clamp body (1) have the same taper, and a plurality of steel claw sandwich cores (3)
The surface of an inner hole formed by the inner surface is contacted with the excircle of the steel claw (7), and plays a role in positioning and clamping simultaneously during clamping; the left part of the steel claw sandwich (3) is connected with a pull rod (6) and a pull rod (6)
Connecting an oil cylinder;
during welding, the steel claw sandwich cores (3) move leftwards under the driving of the pull rods (6), and the steel claw sandwich cores (3) simultaneously shrink towards the center in parallel;
after welding, the oil cylinder pushes the pull rod (6) to move the steel claw sandwich (3) to the right, and the steel claw (7) is loosened.
Before friction welding, the steel claws are placed in the inner holes of the clamp body, the right side wall of the steel claw sandwich has the same taper with the inner holes of the clamp body, and the inner hole surface formed by the inner surfaces of the steel claw sandwich is in contact with the outer circle of the steel claws, so that the steel claw sandwich plays roles of positioning and clamping simultaneously; the left part of the steel claw sandwich is connected with a pull rod, and the pull rod is connected with an oil cylinder; during welding, the steel claw sandwich moves leftwards under the driving of the pull rod, and a plurality of steel claw sandwiches are simultaneously contracted towards the center in parallel to clamp the steel claws; after welding, the oil cylinder pushes the pull rod to enable the steel claw sandwich to move rightwards, and the steel claw is loosened. Therefore, the clamp force can be uniformly distributed, the welding vibration is reduced, the clamping efficiency and the welding efficiency are improved, the electrolytic aluminum welding quality is improved, the welding time is shortened, and the economic benefit of an enterprise is improved.

Detailed Description
As shown in fig. 1, the centering jig for friction welding a steel jaw includes: the clamp comprises a clamp body 1, a steel claw sandwich 3, a pull rod 6 and a steel claw 7;
before friction welding, the steel claws 7 are placed in the inner hole of the clamp body 1, the right side wall of the steel claw sandwich 3 and the inner hole of the clamp body 1 have the same taper, the surface of the inner hole formed by the inner surfaces of the steel claw sandwich 3 is in contact with the excircle of the steel claw 7, and the steel claw sandwich plays roles of positioning and clamping simultaneously; the left part of the steel claw sandwich 3 is connected with a pull rod 6, and the pull rod 6 is connected with an oil cylinder;
during welding, the steel claw sandwich 3 moves leftwards under the driving of the pull rod 6, and a plurality of steel claw sandwiches 3 simultaneously contract towards the center in parallel to clamp steel claws;
after welding, the oil cylinder pushes the pull rod 6 to move the steel claw sandwich 3 rightwards, and the steel claw 7 is loosened.
Before friction welding, the steel claws are placed in the inner holes of the clamp body, the right side wall of the steel claw sandwich has the same taper with the inner holes of the clamp body, and the inner hole surface formed by the inner surfaces of the steel claw sandwich is in contact with the outer circle of the steel claws, so that the steel claw sandwich plays roles of positioning and clamping simultaneously; the left part of the steel claw sandwich is connected with a pull rod, and the pull rod is connected with an oil cylinder; during welding, the steel claw sandwich moves leftwards under the driving of the pull rod, and a plurality of steel claw sandwiches are simultaneously contracted towards the center in parallel to clamp the steel claws; after welding, the oil cylinder pushes the pull rod to enable the steel claw sandwich to move rightwards, and the steel claw is loosened. Therefore, the clamp force can be uniformly distributed, the welding vibration is reduced, the clamping efficiency and the welding efficiency are improved, the electrolytic aluminum welding quality is improved, the welding time is shortened, and the economic benefit of an enterprise is improved.
The steel claw sandwich cores can be simultaneously, parallelly and inwards contracted, so that the clamping force borne by the steel claws is uniformly distributed and is not influenced by the outer diameter of the steel claws to a certain extent. Effectively reduces the vibration in the welding process, ensures the welding quality and reduces the welding cost. The phenomenon that the contraction of the orifice of the common spring chuck is larger than that of the orifice of the common spring chuck is avoided, the requirement of uniform distribution of clamping force is effectively met, and the requirement of steel claw centering is also met.
Preferably, the centering fixture for the friction welding steel claw further comprises a plurality of T-shaped inclined keys 2 which are arranged in inner holes of the fixture body 1 and are fixed and positioned by screws 9 and positioning pins 8, after welding is completed, the oil cylinder pushes the pull rod 6 to enable the steel claw sandwich 3 to move rightwards, and the steel claw sandwich 3 expands rightwards in parallel through the restraint of the T-shaped inclined keys 2. The purpose of loosening the steel claw is achieved. The outer side of the T-shaped inclined key 2 is in precision fit with the inner side of the steel claw sandwich 3, and the T-shaped inclined key plays a role in guiding and restraining the sandwich sleeve 5 in the clamping process.
Preferably, the taper of the inner hole of the clamp body 1 is more than or equal to 15 degrees.
Preferably, the centering fixture for the friction welding steel claw further comprises a core clamping sleeve 5, and an annular groove is formed in an inner hole at the left end of the steel claw core 3 and used for placing the core clamping sleeve 5. In the process of welding the clamp, because the steel claw 7 is subjected to leftward upsetting force, the left end face of the steel claw 7 acts on the right end face of the sandwich core sleeve 5, so that the steel claw sandwich core 3 slightly moves leftward, and a plurality of independent steel claw sandwich cores 3 synchronously contract inward, and the clamping force is further increased.
Preferably, a pull rod nut 4 connected with a pull rod 6 is arranged in an inner hole in the middle of the sandwich sleeve 5.
Preferably, the steel claw sandwiches 3 with the same structure are mutually independent and are not connected with each other.
