The commonly used tools for fixing screws on the surface of the workpiece are electric screwdrivers and manual screwdrivers. Both of these screwdrivers manually attach the screws to the bits of the electric screwdriver or manual screwdriver, and then fix the screws on the surface of the workpiece. The screwdriver is inefficient in fixing the screw, and cannot accurately locate the screw fixing point.
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.
The upper part of the T-bolt is a screw rod, and the bottom end is a T-shaped head. It is equipped with a sleeve with an anchoring plate. The fastening equipment is installed by the anchoring force between the T-shaped head and the anchoring plate. The appearance of the equipment after installation is shown in Figure 1, in which the figure composed of black lines is a component composed of T-bolts and integral sleeves. When constructing civil foundations, the sleeves should be pre-buried first, and the T-bolts will not be used until the equipment is installed. Anchor into the sleeve.
Most of the electroplating used for rivet nuts on the market is environmental protection blue zinc, because the salt spray test time of environmental protection blue zinc can reach 72 hours, that is, three days. This kind of electroplating has a longer salt spray resistance time. In fact, for example, for electroplating white nickel, the salt spray time of white nickel is relatively short, and it usually rusts in a few hours, which is less than 10 hours. However, some can be oiled for electroplating white nickel, and the salt spray time of the rivet nut after oiling can be longer. S series rivet nuts are made of free-cutting iron, which is treated after heat treatment. CLS series rivet nuts are made of easy-to-cut stainless steel. The hardness of low-carbon steel plates without surface treatment must be less than 70RB, and the hardness of stainless steel plates must be less than 80RB.
In order to overcome the technical problem that the screws and nuts cannot be disassembled and assembled at the same time in the prior art, Guangdong Yueluo Hardware Industry Co., Ltd. provides a simple structure and can be quickly disassembled and assembled at the same time in a small space. screw and nut removal tool.
