Service Hotlineslotted screw comprises a screw rod, one end of the screw rod is connected to the middle of the bottom surface of the screw head, the side wall of one end of the screw rod away from the screw head is provided with a screw slot in the vertical direction, the screw The bottom surface of the head is in seamless contact with the top surface of the buffer wear-resistant pad, the buffer wear-resistant pad is connected with the screw rod by threads, and the buffer wear-resistant pad is provided with several shock-absorbing holes equally spaced along the circumference.
The shaft and gear of financial self-service equipment are often connected by elastic straight groove cylindrical pins. When repairing, the traditional disassembly method is to use the shaft and gear as components. After disassembling together, align the punch with the elastic pin by hand, and use a hammer to remove the elastic pin. Pin out. With this disassembly method, the human hand is easily injured, and the disassembly efficiency is low.
Hexagon head bolts are divided into two types: outer hexagon bolts and inner hexagon screws. According to the force mode of the connection, there are ordinary ones and those with reaming holes. The bolts used for reaming holes should be matched with the size of the holes and are used when receiving lateral force. According to the shape of the head, there are hexagonal head and round head. , square head, countersunk head, etc. Generally, the countersunk head is used in places where the surface is smooth and no protrusions are required after connection, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be Larger, but larger in size. Hexagons are the most commonly used. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod. These holes can prevent the bolts from loosening when they are subjected to vibration.
rivet assembly device is provided with a base, the middle of the base is provided with a vertical groove, the bottom wall of the vertical groove extends forward and a horizontal convex block is suspended; the top surface of the convex block is fixed with a vertical rivet Needle and a guide column, the column body of the guide column is covered with a return spring; a downwardly open sliding block is mounted on the convex block, and the upper ends of the rivet needle and the guide column respectively protrude into the sliding block on the top wall of the sliding block. In the riveting pin hole and the guide hole, the inner wall of the riveting pin hole is provided with a large upper and a lower small horizontal step; the upper part of the bottom wall of the vertical groove is provided with a guiding limit rib. Guangdong Yueluo Hardware Industrial Co., Ltd. sets the rivet needle under the workpiece, and uses the upper die punch to press down the workpiece, and the rivet needle completes the operation of the rivet, omitting the operator to turn over and carry the rivet terminal board, thus effectively avoiding the rivet from The phenomenon that the rivet hole comes out. In addition, during operation, the workpiece is placed on the top surface of the slider, and the workpiece guide limit ribs and guide columns are used as shafts and radial limiters respectively. The riveting quality is good, and the purpose of saving time and labor and high efficiency is achieved.
