Service HotlineIn another embodiment of Guangdong Yueluo Hardware Industrial Co., Ltd., the conveying device 3 includes a motor 31 and a circular rotating disk 34, the motor 31 drives the circular rotating disk 34 to rotate, and the circular rotating disk 34 is evenly provided with screws in the circumferential direction. The matching screw accommodating hole 35, the screw enters the screw accommodating hole 35, the motor 31 drives the circular rotating plate 34 to rotate, so that the screw is first slotted by the cutting wheel 42, and then polished by the fixing wheel 48, and the screw is in the screw accommodating hole 35. It is fixed, which is more secure and reliable during the slotting process. Preferably, the circular rotating disk 34 includes a circular rotating disk 32 and a sector-shaped fixed disk 33. The circular rotating disk 32 is evenly provided with screw receiving recesses matching the screws in the circumferential direction, and the recesses and the sector-shaped fixed disk 33 are formed with the screws The matching screw receiving holes face the cutting wheel 42 and the fixing wheel 56 .
The shaft circlip is a mechanical part installed on the slotted shaft and used as a fixed part for the movement of the hole. The inner diameter of the shaft circlip is slightly smaller than the mounting shaft diameter. When installing the shaft circlip, use the circlip pliers, insert the pliers into the pliers hole of the retaining ring, expand the retaining ring, and then put the shaft circlip into the shaft groove.
Guangdong Yueluo Hardware Industry Co., Ltd. discloses an eccentric special-shaped rivet, which has a simple structure and is inexpensive to manufacture. The eccentric shaped rivet includes a cylindrical head and an eccentric polished rod. The diameter of the cylindrical head is larger than that of the eccentric polished rod. The eccentric polished rod is arranged at the lower end of the cylindrical head, and the axis of the eccentric polished rod is not the same as the axis of the cylindrical head. on the same straight line. The eccentric special-shaped rivet has low manufacturing cost and is easy to realize automatic assembly.
Lock washers feature easy installation. 1. Just place the helical tooth surfaces on the inner side of the two washers against each other and place them between the nut and the connecting material; 2. After the nut is tightened, the radially convex surface on the outer side of the lock washer and the contact surfaces at both ends are in an engaged state, and The angle of the slope angle of the helical tooth surface on the inner side of the washer is greater than the thread angle of the bolt; 3. When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen accordingly. Because the frictional force of the outer radial convex surface of the lock washer is greater than the frictional force between the inner helical tooth surfaces. In this state, only the relative dislocation between the inner helical tooth surfaces is allowed to generate a certain lifting tension; 4. When the bolt shrinks, the helical tooth surface of the washer will make the nut return to its original position. So as to achieve 100% anti-loose and tightening effect; 5. Washers are suitable for relatively flat and smooth surfaces; 6. If the connecting material is non-metallic material, a metal plate can be fixed on the connecting material, so that the Use the lock washer; 7. There is no need to use a torque wrench when installing the lock washer; 8. You can choose to use an air tool when installing or removing the lock washer.
With the advancement of technology in various industries, the current structural design of screws has evolved from just simple locking to focusing on work efficiency during the locking process and not destroying the integrity of the objects to be locked. The new cases such as No. 556784 screw improvement and No. 289414 screw that integrates locking, stability, labor-saving, fast and multi-function, which were previously designed and approved and published in the Central Taiwan Bulletin, are the main representatives of screws. It is clear that It is learned that the two cases not only fully improve the shortcomings of the traditional simple locking screws, but also achieve the purpose of substantial improvement of the screws designed in each case in actual use.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: round flat washers, carbon steel color zinc screws, thickened self-locking locking, bottom hole 4.2 carbon steel galvanized pressure plate nut column and other products, We can provide you with the right fastener solution for you.
