Service HotlineA rivet is a nail-shaped object with a cap on one end: in riveting, the parts being riveted are joined by their own deformation or by interference. There are many types of rivets, and they are informal. However, the two ends of conventional rivets are concentric, which is not suitable for special occasions.
At present, the connecting shafts of commonly used food processing knives on the market generally use square bayonet, which is not easy to install parts, and it is time-consuming and laborious when replacing parts; Increased processing costs. There is also a link structure with a circular bayonet on the market, but it is easy to loosen and not firm after the entire food processor is used for a period of time, which affects the use of the machine. Therefore, a connection structure that is easy to operate and simple to process is urgently needed.
The circlip lifting and tightening mechanism includes a lifting mechanism and a tightening mechanism; the lifting mechanism includes a lifting cylinder and a ball screw; the output shaft of the lifting cylinder is connected with the ball screw; the ball screw drives the tightening mechanism to achieve up and down move; the tightening mechanism includes a tightening motor, and the output shaft of the tightening motor drives a pinion sleeved on the output shaft to rotate; the pinion drives the largest gear meshed with it to rotate, and the largest gear is driven by The second largest gear meshed with it rotates; the diameter of the first largest gear is the same as that of the second largest gear; the lower ends of the rotating shafts of the first largest gear and the second largest gear are equipped with rotating discs, and each rotating disc is fixedly installed A probe; two probes can be inserted into the two holes of the circlip at the same time, and the circlip can be tightened or loosened as the motor rotates.
With the rapid development of China's automobile industry, the requirements of body assembly process are constantly improving. Riveting has the characteristics of short process cycle, low noise and low energy consumption, and is widely used in automobile bodies. In the automobile industry, due to the complexity of the body sheet metal structure, there are many cavities, and the riveting tools in some positions will interfere with the structure. Many assembly points cannot use the traditional two-way loading riveting technology, so single-sided riveting is used instead. craft.
When using, after installing the nut and the bolt in place, insert the locking strip from the groove of the bolt, and make the V-shaped locking teeth of the locking strip snap into one of the V-shaped tooth grooves, and push the locking strip into the groove as a whole. The V-shaped locking teeth are stuck in the nut, and the locking strip body is stuck in the groove of the bolt, thereby restricting the relative rotation of the nut and the bolt, and there are threads between the nut and the bolt to restrict their relative sliding, so it can prevent the nut from loosening, even from The bolt falls off; when the nut needs to be disassembled, it is only necessary to pull out the locking strip from the groove, and the nut can be disassembled normally.
