Service HotlineIn order to achieve the above purpose, the technical scheme adopted by the screw in Yueluo Company is as follows.
In 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 57 .
At present, there are mainly the following methods for classifying screws of different lengths mixed together: First, visual identification and manual sorting. This method is time-consuming, labor-intensive and inefficient. Second, the screws are centrifuged and screened according to the quality and size of the screws. However, the quality of screws of the same length is not necessarily the same when the materials of the screws are different. Third, sorting is carried out using a screening device with sieve holes, but the sieve holes are generally simple geometric shapes, which can only roughly distinguish the length of the screws. Moreover, the specific position where the screw falls into the screen hole will also affect the degree of screening. It can be seen that the above-mentioned methods for classifying screws all have the problem of poor effect.
In the repair process of the EDITION 700 gearbox, it is often necessary to replace the piston seal. When replacing the direct gear piston seal, the shaft spring retaining ring on it must be removed before the piston can be taken out for replacement. For the seal, since the piston return spring 3 presses the retaining ring 5 through the spring seat 4 (as shown in Figure 3), it cannot be taken out directly. It is necessary to press down the spring seat before taking out the retaining ring. Without special tools, it is not easy to remove the retaining ring. At present, it is a time-consuming, labor-intensive and unsafe job that requires multiple people to use a screwdriver and a prying board to forcefully squeeze and pry to remove the retaining ring.
screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the parts of the object step by step. Since the parts to be fixed are different, different types of screws are required for different applications. Press screw is a new type of fastener applied to thin plate or sheet metal. The principle is to press the embossed teeth into the preset holes of the sheet metal. The diameter of the general preset holes is slightly smaller than the outer diameter of the pressure riveting screw. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect. However, the existing pressing screws are easy to loosen due to long use time or frequent vibrations, which is prone to certain hidden dangers.
