A pressing device and riveting machine

Abstract

The invention discloses a pressing device and a riveting machine. The pressing device comprises a fixed base, a lower pressing block, an upper pressing block, a pressing holding plate and an elastic assembly. The lower pressing block is arranged on the fixed base, the lower pressing block comprises a lower pressing block body and a clamping connecting column extending upwards from the top surfaceof the lower pressing block body, and the bottom surface of the lower pressing block body is fixedly connected to the fixed base. The upper pressing block is disposed above the lower pressing block, and the upper pressing block comprises an upper pressing block body. An avoiding groove is formed in the upper pressing block body, and the clamping connecting column is movably connected into the avoiding groove in a sleeved mode so that the lower pressing block is spliced with the upper pressing block. The pressing holding plate is arranged above the upper pressing block, and pressing holding plate mounting holes are formed in one end of the pressing holding plate. Limiting bolts penetrate through the pressing holding plate mounting holes and are connected to the upper pressing block in a threaded mode to limit one end of the pressing holding plate, and an abutting portion is further formed in the surface, facing the upper pressing block, of the pressing holding plate and at the positioncorresponding to the clamping connecting column. The abutting portion abuts against the end surface of the clamping connecting column. The elastic assembly is disposed between the pressing holding plate and the fixed base and is connected with the pressing holding plate and the fixed base, and a clamping opening is formed between the top surface of the lower pressing block and the bottom surface of the upper pressing block. The pressing device is convenient to operate and has a good clamping effect.

Description

technical field The invention relates to the field of riveting devices, in particular to a pressing device and a riveting machine. Background technique Cars are the most important means of transportation in modern life. With the advancement of technology and the requirements for comfort, the peripheral accessories of cars are becoming more and more refined, and the car sunroof is one of the main additional accessories. The operation of the sunroof requires a guiding flexible shaft to control its opening or closing. The flexible and toughness of the guiding flexible shaft is used to achieve its transmission purpose. The currently used guiding flexible shaft is a round shaft with a helical flexibility and toughness as a whole. One end is first chamfered and then clamped into the high-hardness POM end cover. Since the end cover must reach a high temperature of about 550 degrees, it can be smoothly clamped into the guide flexible shaft. After the end cover cools down, it will c...

AI Technical Summary

Problems solved by technology

At present, the production of the flexible guide shaft is manually ground at one end of the flexible guide shaft. At high temperature, the end cover is manually riveted into the tapered end of the flexible guide shaft. The purely manual production leads to a very high defect rate and high production efficiency. Disadvantages and high labor costs, unable to meet market supply demand for a long time are its shortcomings
