Further, it also includes a motor, the motor is provided with a thruster that makes the cutting wheel move towards the conveying device, the other end of the motor is provided with a bearing, the output end of the motor is provided with a special-shaped wheel, the special-shaped wheel is toothed with the bearing, and the motor drives the special-shaped wheel to rotate. , move the cut-off wheel closer to or away from the conveyor.
Screw (pinyin: luógǎn, English: screw): a cylinder with a spiral groove cut on the outer surface or a cone cut with a tapered spiral groove. The screw has a different head, the head is called an external hexagon screw. There are others, such as large flat screws, socket head screws and so on.
Common types of common screws All kinds of common screws (20 pieces) a. Slotted: a word ( Minus ) b. Phillips: cross ( Plus ) c. Phil-Slot: a word / cross d. Hex Socket: hexagon socket e. One Way: One-way (can only be locked in, not out) A-4: Head Code/ head shape. a. Flat: Flat head (after locking, the top is flush with the work piece) b. Oval: salad head, O head, countersunk head screw unit of measure screw unit of measurec. Round: round headd. Pan: round flat heade. Truss: large round flat headf. Hex: hexagon head. A-5: Finish Code/Appearance treatment. Metric Self-tapping screw: Mark Tapping Type directly behind the product name. Ex: M3 x 6 –PPB, Tapping Type: M3 self-tapping screw, 6mm long, cross, round flat head, black plated. Generally, it is determined by product type or mark. For Sheet Metal or plastic parts. *Pitch = Threads per inch
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
