In specific implementation, since the thickness of the sheet metal part 1 for the automobile seat is usually 3 mm thick, a boss 11 is punched at a position where the nut is originally required to be welded in a punching manner, and the punched boss 11 is not too high (more than 2 pitches can be used when the corresponding bolt is screwed), the wall thickness of the boss 11 is almost equal to the thickness of the original sheet metal part 1, and the thickness is enough for tapping internal threads. By arranging the internal threads on the inner surface of the convex column 11, the convex column 11 with the internal threads is used for replacing the nut and the bolt in a screwed manner, so that the purchase cost of the nut and the cost of welding the nut are saved, only tapping equipment is needed to be arranged in a workshop, welding equipment is not needed to be arranged, the input cost of a factory is reduced, and the time spent on tapping is short compared with the welding operation, the production period of a workpiece is shortened, and the benefit of the factory is improved.

In one embodiment, the pushing member 35 includes a stud threaded through the upright 31, one end of the stud is rotatably connected to the pushing plate 34, the other end of the stud passes through a side of the upright 31 facing away from the pushing plate 34, a guiding rod 341 is further disposed on a surface of each pushing plate 34 corresponding to the upright 31, and the guiding rod 341 is slidably disposed through the upright 31. Turning the studs moves the push plate 34 in a direction toward and away from the corresponding column 31.

Preferably, one end of the stud, which passes through the upright post 31, is provided with an inner hexagonal cup head, when the stud is rotated, one end of the inner hexagonal wrench is inserted into the inner hexagonal cup head, then the inner hexagonal wrench is rotated to drive the stud to rotate, and after the stud is rotated in place, the inner hexagonal wrench is taken down, so that other people can not rotate the stud easily under the condition that no inner hexagonal wrench exists, and the situation of false touch is avoided.

In one embodiment, a limiting member 36 is provided on each stud 31 at the location of the corresponding stud for limiting the rotation of the stud. The restricting member 36 is a bolt which is screwed to the top of the column 31, and one end of the bolt is abutted against the corresponding stud.

In particular, when the stud is rotated in place, the bolt is rotated to make one end of the bolt abut against the stud, and at this time, the stud is hardly rotated due to the influence of the abutting force, so that the push plate 34 is ensured not to be displaced. When the size specification of the sheet metal part 1 changes, the bolts can be unscrewed at the moment, the stud is unlocked and rotated, then the stud is rotated to adjust the moving distance of the push plate 34, and the sheet metal part 1 with the changed specification is matched again.

In particular, compressed gas in the workshop is connected with the air inlet 47 through a switch valve, when the switch valve is opened, high-pressure gas enters the air blowing hole 41, the gas entering the air blowing hole 41 pushes the air guiding plate 43 to move upwards in the air blowing hole 41 until the compressed gas moves out of the air blowing hole 41, then the compressed gas is blown out from a gap between the air guiding plate 43 and the top of the air blowing hole 41, the blown gas is guided by the air guiding plate 43 and is blown on the surfaces of the corresponding first supporting table 32 and the second supporting table 33, and chips on the surfaces of the first supporting table 32 and the second supporting table 33 are blown away. In the process that the air guiding plate 43 moves upwards in the air blowing hole 41, the baffle 45 is driven to move to compress the elastic piece 46, and after the switch valve is closed, the elastic force of the elastic piece 46 pushes the baffle 45 to move downwards to drive the air guiding plate 43 to reset. In this way, the worker only needs to control the switch of the compressed gas, and does not need to hold the air gun to purge the surfaces of the first support table 32 and the second support table 33, so that the work is simple and convenient.
