Punching needle assembly for punching and riveting water discharging chamber assembly of automobile air-conditioner

Abstract

The invention provides a punching needle assembly for punching and riveting a water discharging chamber assembly of an automobile air-conditioner. The punching needle assembly comprises a guide cylinder arranged on an output shaft of an air cylinder, the guide cylinder is internally provided with a sliding cavity of which one end is provided with an opening, the sliding cavity is internally and slidably provided with a punching needle, sliding grooves penetrate through the side wall of the punching needle in the direction parallel to the axis, the sliding grooves are symmetrically formed in the two sides of the punching needle in the radial direction of the punching needle, the opening of the sliding cavity is provided with an end cover, the end cover is provided with a through hole matched with the punching needle, and the through hole is internally provided with a check block sliding in the sliding grooves, the punching needle is provided with a threaded hole in the radial direction,openings of the two ends of the threaded holes are located in the sliding grooves respectively, the threaded holes are internally in threaded connection with a limiting column, the sliding cavity isinternally provided with a limiting part capable of being in contact with the end face of the punching needle, and the limiting part is adjustably arranged on the guide cylinder in the axial directionof the guide cylinder. The punching needle assembly for punching and riveting the water discharging chamber assembly of the automobile air-conditioner has the advantages that the automatic work can be achieved, the sliding distance of the guide cylinder can be adjusted conveniently, and the stroke can be adjusted.

Description

technical field [0001] The invention specifically relates to a punching needle assembly for punching and riveting of a water chamber of an automobile air conditioner. Background technique [0002] Such as Figure 9 , 10 As shown, the grille 17 of the lower water chamber of the automobile air conditioner is generally a rectangular hollow strip, and the upper surface is provided with a number of insert mounting holes 18. During general installation, inserts 19 need to be installed in the insert installation holes 18. Riveting is carried out to the side of inserting piece 19 and inserting piece installation hole 18, namely stamping forms a groove 20, to fix inserting piece 19 and automobile air conditioner water chamber grid 17, prevent inserting piece from coming off. [0003] However, at present, the grille installation inserts of the automobile air conditioner are generally assembled manually, and the riveting operation is also performed by hand tools. The work efficiency i...

Problems solved by technology

[0003] However, at present, the grille installation inserts of the automobile air conditioner are generally assembled manually, and the riveting operation is also performed by hand tools. The work efficiency is low and does not meet the needs of modern production. Therefore, there is an urgent need for a device that can be automated.
