Summary of information:We have more than ten years of production experience in the screw industry, the main products are: fish eye bolts, embed...

If the above-mentioned nuts and screws are used as a kind of fasteners that can prevent others from being disassembled, such as when installing iron doors-steel windows, people usually tighten the nuts first, and then use a welding machine to weld the nuts and screws. To prevent the nut from loosening, it may be necessary to use a tool to mill the threads on the screw. It can be seen that this approach is very inconvenient.

The manual dismantling of the rivets of the automobile frame delays the production cycle of the product and increases various production costs, so a special tooling is desperately needed to meet the actual needs.

In order to achieve the above purpose, Yueluo provides the following technical solutions: threaded rivets include a nail rod, an expansion piece, and a nail sleeve, one end of the nail rod is provided with a mounting piece, and the side of the mounting piece away from the nail rod is movably installed with a mounting piece. There is a driving mechanism. The driving mechanism includes a mounting cylinder and a movable rod. A cross groove is formed at one end of the mounting piece close to the driving mechanism. The rod is movably installed on the inner side of the installation cylinder, and one end of the movable rod close to the cross groove is fixedly provided with a cross connecting piece that matches the cross groove, the cross connecting piece is matched with the cross groove, and the movable rod is far away from the cross groove. One end of the cross connecting piece is fixedly provided with a fixing piece, the fixing piece and the installation cylinder are screwed together by threads, the expansion piece is sleeved on the outer side of the nail rod, and the nail sleeve is movably installed on the nail rod away from the driving mechanism The outer side of one end of the nail rod is movably installed with a fixing mechanism.

The maximum unscrewing torque of the lock nut is affected by many factors. For the research on the low-cycle fatigue performance of the lock nut, the pitch diameter of the thread, the helix angle and the bevel angle of the thread remain unchanged. Only the maximum elastic restoring force FNmax and the equivalent friction angle ρe of the thread piece will appear to a certain extent after repeated use. Change. Therefore, it is only necessary to analyze the variation law of the maximum unscrewing moment when the lock nut is subjected to cyclic load from these two aspects.

The circlip travel mechanism includes a travel cylinder and a travel plate connected with the push rod of the travel cylinder; the travel air cylinder can control the travel plate to be inserted into the circlip press-out and positioning mechanism, and the circlip lifting and tightening mechanism; the travel plate The surface of the device is provided with a groove for placing the circlip; the height of the groove is the height of one circlip.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: FPV model aircraft frame nuts, pressure plate inner screw studs, rectangular nuts, coarse thread nuts and other products, we can provide you with suitable tightening. Firmware Solutions.
