Service Hotlinemet a customer before, and the stainless steel screws needed by the company need to be prevented from loosening. Simply put, the stainless steel screw should be used on the product material so that the stainless steel screw will not fall off lightly. The screws are required to be more tightly connected with the product material. For the solution of stainless steel screw anti-loosening, there are two solutions. Next, the following two solutions to prevent loosening of stainless steel standard parts are presented. The first is to use the resilience of special materials, such as engineering resin materials, which have good resilience. Attach it to the stainless steel screw thread. Make it mechanically rub against the nut, or material product. Generate vibration and absolute resistance. Completely solve the problem of loose screws. The second, simply put, is to apply a layer of glue on the thread of the stainless steel screw, the so-called dispensing. This glue is called drop-resistant glue. This glue has good properties such as high stickiness and non-toxicity. This glue is applied to stainless steel screws, and when dry, it adheres extremely well. The stainless steel screw thread can be combined with the nut thread, or after the product threaded hole is joined, resulting in a super tightening effect. Play a super good anti-loosening effect.
Contents of the utility model The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a hexagon socket head screw that is easy to disassemble and assemble. In order to achieve the above purpose, the technical scheme adopted by the present invention is as follows: a hexagon socket screw, which includes a cylindrical screw head and a cylindrical screw below the screw head, the screw is provided with threads, and an integrated screw is designed between the screw head and the screw. The circular skirt pad has a hexagonal depression along the axial direction on the screw head, and is characterized in that two symmetrical flat grooves are opened on the upper part of the side wall of the hexagonal depression of the screw head, and the lines of the two flat grooves overlap. Guangdong Yueluo Hardware Industry Co., Ltd.'s socket head screws are compared with ordinary socket head screws. A notch is designed in the inner hexagon space at the top of the screw. In terms of tool use, it can be avoided that the socket head screws must be equipped with the corresponding socket head tools. disadvantages. The improved hexagon socket screw can not only use the matching hexagon socket tool, but also use the traditional flat-blade screwdriver, which is more convenient to use.
Bolts are widely used as common fasteners. The traditional T-bolt consists of a head, a screw and a tail. The head is a long plane. During the use of the T-bolt of this structure, the T-bolt and the groove The contact surface of the track is a smooth surface, its friction force is not large, its connection is not firm enough, and it is easy to fall off. For this reason, some people design the head as a bevel to increase friction, but only one bevel is in contact with the part in this design, and the sealing is not very good
Gaskets are widely used in the machinery industry. According to the different needs of machinery and equipment in different industries, the structural forms of the sealing points are also different. Plum washer is one of the commonly used seals. It is commonly used between the pump and the motor coupling. In the actual production process of the enterprise, it is found that due to the influence of the material and structure, this type of gasket in common use can withstand impact force. Small, the septum is easily damaged. Because the current plum washers are all one-piece structures, even if one or several of the partitions are damaged, they need to be replaced as a whole. Although the value of a single plum washer is low, it needs to be shut down for maintenance and replacement almost every week. It also seriously affects the normal production of the enterprise, and the one-piece plum blossom gasket is also difficult to repair, adding unnecessary use costs to the enterprise. For this reason, the plum blossom gasket needs to be improved to strengthen the impact resistance of the gasket, and can be repeated Maintenance and use, prolong the maintenance cycle of the equipment, and ensure the normal production of the enterprise. The purpose of the utility model Yueluo is to solve the above-mentioned deficiencies in the existing technology, improve the existing technology, and provide a simple structure, which strengthens the impact resistance of the gasket, and can be repeatedly maintained and used to prolong the maintenance of the equipment. The cycle guarantees the plum blossom elastic washer normally produced by the enterprise. In order to achieve the above purpose, Yueluo is achieved through the following technical solutions-namely a plum blossom elastic washer, including an elastic washer body with a partition, the technical point is that the washer body is composed of a washer base and a partition that is independent of each other. , the septum and the gasket base are fixedly connected into one through the fixing piece. In order to further strengthen the impact resistance of Yueluo, the contact parts of the spacer and the washer base are respectively processed with a limited clamping table and a matching groove, so that the spacer and the washer base can be better integrated into one. According to the different specifications of the torx washer, the spacer and the washer can be fixed as a whole by rivets; or by screws. In addition, a semi-rigid tightening ring with grooves is embedded inside the washer base, and the width of the tightening ring is smaller than the width of the washer base; the ends of the rivets or screws are located in the grooves of the tightening ring, so as not to affect the performance of the torx washer JH is often installed. After the above improvement, Yueluo has improved the one-piece structure of the plum-blossom washer into a split structure and adopted a variety of fixed structure forms, so it has a simple structure, strengthens the impact resistance of the gasket, and can be repeatedly maintained and used. , Extend the maintenance cycle of the equipment and ensure the advantages of the normal production of the enterprise.
T-bolts have been widely used in the fields of aviation, aerospace and defense due to their good positioning and anti-shedding effects. Its related standards have special requirements for accurate positioning, anti-falling off, and dimensional consistency of T-bolts. This requires that the position, size and shape and position tolerance of the anti-fall hole of the T-bolt shank must be controlled within a certain range. Therefore, the processing method of the anti-shedding hole is particularly important. Since the machined anti-shedding hole is located at the position of the rod, the milling processing efficiency is too low, the product cost is high, and there is a large machining error. When conventional drilling is used, the consistency of the anti-shedding hole size cannot be guaranteed. To solve the above problems of low efficiency and dimensional instability
