Description

Automatic riveting device for cup mouth Technical Field The invention belongs to the field of automobile air conditioners, and particularly relates to automatic connecting pipe riveting of an evaporator side outlet pipe platform. Background The existing installation mode of the connecting pipe of the side outlet pipe platform of the evaporator product is 2 modes, namely, the first mode is that the connecting pipe is directly installed in a clearance fit mode, and the second mode is that the connecting pipe is knocked by a tool in an interference fit mode. However, both the two modes have certain defects, the first mode easily causes the condition that the connecting pipe is separated or even falls off in the process of feeding the product into the furnace, and the second mode also has the risks of not knocking in place or missing the installation. Disclosure of Invention The invention aims to provide an automatic riveting device for a cup mouth, which is used for riveting a connecting pipe and a collecting pipe in a rivet pulling mode, so that automation of connecting pipe installation is realized. In order to achieve the above purpose, the technical scheme of the invention is as follows: The automatic riveting device for the cup mouth comprises a device support, an air cylinder and a gear rack mechanism, wherein the device support comprises 2 guide shafts and 4 fixing plates, the 2 guide shafts are movably connected with a first transverse fixing plate and a third transverse fixing plate, the other 2 fixing plates are fixedly connected with the guide shafts, the first end of the air cylinder is fixed on the first fixing plate through bolts, the tail end of the air cylinder is fixed on the second fixing plate through bolts, the back parts of the second air cylinder and the second fixing plate are fixedly connected through bolts, the tail end of the second air cylinder is fixed with a connecting plate through bolts, the connecting plate is fixedly connected with the third transverse fixing plate through bolts, and the 2 riveting heads are respectively fixed on the connecting plate through the gear rack mechanism. The guide shafts can move up and down, the 2 fixing plates are fixedly connected with the guide shafts and move up and down along with the guide shafts, the movable connection mode is a linear bearing, and the fixed connection mode is a bolt. And the 2 movably connected fixing plates are distributed with the 2 fixedly connected fixing plates in a staggered manner. The device has the advantages that the device can automatically rivet the inlet and outlet pipes, the first cylinder drives the outer part of the inlet and outlet pipes to realize riveting, the second cylinder drives the 2 rivet joints to realize the inner riveting of the inlet and outlet pipes, and the internal and external riveting structure improves the stability and the working efficiency of products. Drawings FIG. 1 is a schematic diagram of the structure of the present invention; FIG. 2 is a drawing showing the ascending operation state of the rivet head; Fig. 3 is a drawing showing a descending operation state of the rivet joint. Detailed Description The invention will be further described with reference to the drawings and examples. Referring to fig. 1-3, the first end of the first cylinder 1 is fixedly connected with the first fixing plate 8 through bolts, and the second end of the first cylinder 1 is fixedly connected with the second fixing plate 10 through bolts. The back of the second cylinder 2 and the second fixing plate 10 are fixedly connected through bolts, the tail end of the second cylinder 2 and the connecting plate 12 are fixedly connected through bolts, and the connecting plate 12 and the third fixing plate 11 are fixedly connected through bolts. The first fixing plate 8 and the third fixing plate 11 are movably connected with the 2 guide shafts by adopting a linear bearing 9, and the second fixing plate 10 and the fourth fixing plate 13 are fixedly connected with the 2 guide shafts by adopting a bolt and the like.
