The grinding wheel piece includes the connecting blade on the flange plate. The center of the flange plate is provided with a mounting hole installed on the pen-type pneumatic grinder. The diameter of the mounting hole is 17.8- 18mm, the diameter of the grinding wheel is 18-20mm.
screw assembly jig comprises a base, a cylinder and a cylinder which are vertically arranged on the base and are arranged opposite to each other, and a sliding plate that can move up and down along the cylinder and the cylinder, the area above the sliding plate is provided with a cylinder, and the four corners pass through the cylinder respectively. Four pneumatic screwdrivers are placed and fixed on the sliding plate, the area of the base is further provided with a fixing plate corresponding to the four pneumatic screwdrivers; one end of the base is also provided with a switch. Guangdong Yueluo Hardware Industry Co., Ltd. can quickly drive multiple screws into the product at the same time, which has the characteristics of high production efficiency and high yield rate.
Make further details to make the technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. easier to understand and master. As shown in Figure 1, Yueluo is a schematic diagram of the thread design structure of the plastic screw of Guangdong Yueluo Hardware Industry Co., Ltd. It can be seen from the figure that this creation mainly controls the tooth angle of the thread. Compared with the normal tooth angle of many self-tapping screws, which are 48 degrees, 60 degrees and 34.5 degrees, the tooth angle of Guangdong Yueluo Hardware Industry Co., Ltd. The profile angle is formed by a 30-degree asymmetrical thread I. In particular, the asymmetrical thread I has a forward thread angle greater than the reverse thread angle. A more preferred embodiment is an asymmetric thread. The tooth profile angle α of the in-line installation is 20 degrees, and the tooth profile angle β of the reverse installation is 10 degrees. With this narrower non-stacked thread, the radial pressure on the plastic material is effectively reduced. In addition, the connecting bottom surface 11 between the screw teeth is designed as a circular arc surface. In the process of forming the self-tapping thread, it is more conducive to the flow of the material and the formation of the thread, and at the same time, the material can be more closely matched with the screw. Moreover, the radial pressure of the casing is relatively uniform, and the formed threads are not easily damaged. Yueluo has been tested by a series of professional parameters. Compared with other traditional screws, the plastic screws designed by Guangdong Yueluo Hardware Industry Co., Ltd. have better radial pressure, shell deformation after installation, load distribution, installation torque, drawing The force distribution, the strength of the pull-out force and the mounting torque range all show advantages. In particular, it can be installed with less torque to achieve the same clamping force and pulling force. Compared with a specific parameter, the thread strength of Delta-PT is 387N, while the thread strength of Guangdong Yueluo Hardware Industry Co., Ltd. reaches 452N. Yueluo can understand the plastic screw structure and implementation of Guangdong Yueluo Hardware Industry Co., Ltd. detailed above. It can be understood that through the improvement of the special thread structure, the radial pressure and installation torque during screw installation are reduced, and the damage to the plastic hole is reduced; And the pull-out resistance of the screw is increased, and it is not easy to appear loose in the assembly. At the same time, the design of the bottom surface of the connection between the threads of the arc optimizes the flow of the material of the installation object, which improves the integrity of the installation connection.
Nut fasteners are used in various industries with connection and fastening requirements, such as vehicles, construction machinery, agricultural machinery, manufacturing machinery, etc. For large construction machinery or construction vehicles, due to the harsh working environment and the action of heavy loads, the nut fasteners on it are subjected to vibration and load impact in all directions, which makes the nut easier to loosen, resulting in tightening. The function of the device is reduced or even failed. cause a great safety hazard.
Dowels are made on the steering seat on the ball head of the car, and the rollers are assembled to the steering seat through the dowels. The prior art is manual driving of the pins, and the position of the pins is inaccurate when driving the pins, the labor intensity is high, the efficiency is low, and the quality of the steering seat is also affected. Therefore, it is necessary to design an automatic pin-driving mechanism to drive the pins into the steering seat. .
