Service HotlineIn some embodiments, the rivet fixing mechanism includes a left moving block, a right moving block, a return spring and a bracket, wherein both the left moving block and the right moving block are movably mounted on the bracket, and the left moving block and the right moving block are connected by a return spring, The insertion mouth can extend between the left moving block and the right moving block, and withstand the left moving block and the right moving block. The left moving block is provided with a left half hole, and the right moving block is provided with a right half hole matching the left half hole. hole. Therefore, when the insertion nozzle is not inserted, the left moving block and the right moving block can be combined together by the return spring, so that the left half hole and the right half hole are combined into one hole to fix and position the rivet, and when the insertion nozzle is inserted When , the left moving block and the right moving block will be pushed up by the insertion mouth to separate the left half hole and the right half hole, so that the rivet is no longer fixed and can be inserted with the movement of the insertion mouth.
The retaining ring with an open ring structure is a commonly used mechanical part. It has standardized design standards. Its main function is to fasten the ring-shaped parts on the shaft, which can prevent other parts mounted on the shaft from moving. kinds of fasteners. In the prior art, the retaining ring is mainly processed by stamping, which has the following defects: 1. The material utilization rate is low;
The production of non-standard round flat pads can only be processed on ordinary lathes without punching machines. Processing with round steel is difficult, material waste is large, tool loss is large, and efficiency is low. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a non-standard circular flat pad lathe processing fixture, which is suitable for the production of various non-standard circular flat pads. Yueluo is realized in this way. It includes a hollow square support, a bolt and a circular machining groove. It is characterized in that a circular machining groove is left on one surface of the hollow square support. There are 4 bolts evenly connected. The advantages of Yueluo are: 1. Reduce the difficulty of processing; 2. Save materials (can use corner waste); 3. Reduce tool wear; 4. Improve production efficiency.
Nuts are very common fasteners. Generally, the torque cannot be limited when the nut is twisted. The degree of tightness of the nut is mostly judged by the worker's experience. In this way, when the nut is over-tightened, it will lead to the destruction of the thread pair, thereby shortening the fastener. The life of the nut may even cause the bolts to be pulled off in severe cases; and the nut is too loosely screwed, which will lead to the problem of insecure fixing.
Two-combination screw refers to a screw and a flat washer, or a spring washer, or a square washer, or a two-piece combination with an external tooth lock washer. Then there are all the standard types of two combination screws! The following is a brief introduction: 1. The second combination screw with spring washer refers to the combination screw with a spring washer. The spring washer is a spring washer specially used for combination screws, not the ordinary spring washer that we usually use. 2. The two-combination screw of the trim pad refers to the combination screw of the screw with a flat pad. The size of the flat pad and the thickness of the flat pad can be customized. Can be customized according to customer requirements. Flat pads are punched out by punching machines. 3. The combination screw with two external teeth refers to the screw with an external tooth combination screw. Many customers, especially electric power customers, use this external tooth two combination screw to break the paint and make the screws on the iron plate. All can be powered on. 4. Two combination screws with a square pad refer to a square pad with a square pressure line for the screw. This square pad crimping two combination screw is used on the terminal, and the function is used for crimping and wiring.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: countersunk head hexagon socket head cap expansion bolts, GB58 slotted nuts, nut combination sets, welded step nuts and other products, we can provide you with suitable fastening products piece solution.
