Service HotlineIn some embodiments, the rivet fixing mechanism includes a left moving block, a right moving block, a return spring and a bracket, wherein both the left moving block and the right moving block are movably mounted on the bracket, and the left moving block and the right moving block are connected by a return spring, The insertion mouth can extend between the left moving block and the right moving block, and withstand the left moving block and the right moving block. The left moving block is provided with a left half hole, and the right moving block is provided with a right half hole matching the left half hole. hole. Therefore, when the insertion nozzle is not inserted, the left moving block and the right moving block can be combined together by the return spring, so that the left half hole and the right half hole are combined into one hole to fix and position the rivet, and when the insertion nozzle is inserted When , the left moving block and the right moving block will be pushed up by the insertion mouth to separate the left half hole and the right half hole, so that the rivet is no longer fixed and can be inserted with the movement of the insertion mouth.
With the continuous improvement of automation technology, human participation in the production process is gradually decreasing, especially in the processing of some small parts, the manual processing efficiency and accuracy are low. Whether the screws can be stably picked up and installed automatically is of great help to improve automated production.
Nut fasteners are used in various industries with connection and fastening requirements, such as vehicles, construction machinery, agricultural machinery, manufacturing machinery, etc. For large construction machinery or construction vehicles, due to the harsh working environment and the action of heavy loads, the nut fasteners on it are subjected to vibration and load impact in all directions, which makes the nut easier to loosen, resulting in tightening. The function of the device is reduced or even failed. cause a great safety hazard.
The flat key transmits torque on the side, has good neutrality, is easy to assemble and disassemble, and cannot realize the axial fixation of the parts on the shaft. Ordinary flat key: Type A, Type B, Type C, Type A is used for shaft grooves machined by end mills. The key is well fixed axially in the groove, but the stress concentration caused by the groove on the shaft is large; Type B is used for disc milling cutters. The machined shaft groove, the stress concentration of the shaft is small; the C type is used for the shaft end; it is suitable for high-speed, high-precision or occasions under variable load and impact, such as fixing gears, sprockets and other rotating parts on the shaft. Guided flat key: The key is fixed on the shaft with a screw, the key and the hub groove are in dynamic fit, and the parts on the shaft can move axially. For the convenience of starting the key, there is a key-starting screw hole. Use the occasions where the axial movement of the parts on the shaft is not large, such as the slip gear in the gearbox. Feather key: The key is fixed on the axle, and the parts on the shaft can move axially with the key; it is used in the occasions where the axial movement of the parts on the shaft is large;
Hexagon socket head cap screws are indispensable industrial necessities in daily life and have important tasks in industry. But ordinary hexagon socket head cap screws must be installed and disassembled with special tools. For ordinary users, some simple disassembly and maintenance work are often unable to be handled due to lack of tools.
