Service HotlineWashers are common parts that are annular or annular after compression. The existing standard washers include flat washers, spring washers, serrated lock washers, saddle washers, etc. The end faces are mostly flat or flat after compression. , so it is in surface contact with the workpiece. Generally, after the two workpieces are locked by washers, bolts and nuts, the workpieces cannot move in any direction, so as to achieve the purpose of tightening the two workpieces. In actual production, some workpieces are still required to be properly translated in a certain direction after locking. In order to achieve this requirement, the usual practice is to open a waist-shaped hole on the workpiece that needs to be moved, and the zigzag-shaped bushing is fitted with a flat washer after passing through the waist-shaped hole, as shown in FIG. The edge of the hole is located in the space enclosed by the bushing and the flat washer, and a gap is formed between the workpiece and the bushing and the flat washer, so that even if the bolt passes through the flat washer, the bushing and the workpiece in turn, it is threaded and locked with the nut. tight, the workpiece can still translate along the length of its girdle hole. Obviously, this method can achieve the requirement of proper translation of the workpiece, but the following deficiencies can still be found in the actual assembly. First, before locking, the bushing, washer and workpiece are separated from each other, so it is more inconvenient to assemble; secondly, the lining is The separation structure of the sleeve and the gasket is inconvenient to manage, and the disassembled gasket and bushing are easy to lose and affect the use again.
Yueluo provides a thin-plate rivet method, which includes the following steps: providing a metal thin plate, a rivet and a thin-plate rivet fixture, the outer edge of the rivet is provided with an engaging structure, and the thin-plate rivet fixture includes a rivet head and a thin plate rivet fixture. The riveting head has a convex rib on the surface of the rivet head; a riveting hole is formed in the thin metal; The two sides of the metal sheet are extruded so that the protruding ribs are embedded in the metal sheet, so that the metal sheet is deformed, and the inner edge of the rivet hole shrinks inward to fix the occlusal structure.
Yueluo Guangdong Yueluo Hardware Industry Co., Ltd. provides a rivet-oriented positioning riveting tool to overcome the shortcomings of the existing technology. The rivet is placed on the tool, and then placed in the riveting machine together with the product for riveting. In the same way, the scrap rate is reduced and the production efficiency is greatly improved. In order to achieve the above purpose, a rivet guide positioning riveting tool is designed, which includes a riveting positioning block and a riveting lower die, which is characterized in that a riveting positioning block is arranged above the riveting lower die. The riveting positioning block includes a positioning pin and a rivet yielding hole, a through hole is arranged in the center of the riveting positioning block, a rivet hole is arranged on one side of the through hole, and a number of positioning pins are arranged on the riveting positioning block around the through hole. . There are five positioning pins. The riveting lower die includes a countersunk head screw hole, a rivet guide block and a positioning hole. The riveting lower die is a stepped module. The left side of the riveting lower die is provided with a countersunk head screw hole, and the right side of the riveting lower die is provided with a countersunk head screw hole. The guide block is provided with several positioning holes on the riveting lower die located in front of the guide block. There are two positioning holes. The center of the guide block is provided with an escape hole. Compared with the existing technology, Guangdong Yueluo Hardware Industry Co., Ltd. has a rivet-oriented positioning riveting tooling. The rivets are placed on the tooling, and then placed in the riveting machine together with the product for riveting, which solves the problem of manual knock-in. The efficiency is low, and the riveting can be riveted without deviation without manual righting during riveting, so that the quality of the products produced is the same, the scrap rate is reduced, and the production efficiency is greatly improved.
At present, the commonly used locking structure is a split pin (hereinafter referred to as a cotter pin type adjustment nut) or knocking the sheet on the adjustment nut into the steering knuckle groove (hereinafter referred to as a sheet type adjustment nut), these two structures are mainly used in single row Bearings are barely used in bearing units and hub bearing units. The former has a complicated structure and the cotter pin is easy to fall off; the latter requires workers to control the press-in force. Too much pressure can easily lead to the cracking of the sheet structure on the adjusting nut, and too little pressure can easily make the adjusting nut failure, and is impacted in the axial direction.
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.
