Summary of information:We have more than ten years of production experience in the screw industry. The main products are: embedded chip nuts, m...

The grooved embedded parts are pre-embedded in concrete, and then placed in the groove with T-bolts. After adjusting the fixed position, the fixed object is locked with a nut to achieve the fixing effect. When the grooved embedded parts are embedded vertically in the concrete or at a certain angle to the horizontal line, the T-bolts are likely to move in position before they are tightened. In particular, when fixing heavy equipment, multiple T-bolts are required, and multiple groups of workers are required to help and positioning is difficult, and the installation process is complicated.

Fasteners are an indispensable necessity in our lives and are used to flexibly fix two objects. However, in applications such as automobiles, large construction machinery and factories, the nuts often come loose and then fall off, resulting in frequent dangers and great dangers. Threats to people's lives and property.

The retaining ring is an industrial accessory that can function as support, buffering, braking, height adjustment and angle adjustment. The inner diameter of the retaining ring for the shaft is slightly smaller than the diameter of the assembly shaft. When the retaining ring for the hole is selected, the outer diameter of the retaining ring is slightly larger than the diameter of the assembly circular hole. The retaining ring mainly plays the role of axial fixation. The surface plus the retaining ring is fixed with a high degree of centering.

In machine tool processing, it is often necessary to calibrate and debug the probe. The method of manually correcting the detection is inefficient and the accuracy is unstable. In addition, accidents such as collisions will occur. However, calibration tools such as ring gauges are expensive, have large working strokes and poor versatility. Technical realization elements: In view of the above content, it is necessary to provide a positioning pin for probe calibration to solve the above problems. A positioning pin is used for calibrating a probe, the positioning pin includes a connected cylinder and a cylinder, the cylinder is used to be installed on a jig in a machine tool, and the end of the cylinder away from the cylinder is provided with a measuring hole to calibrate the probe. Further, the positioning pin is also provided with a chip removal hole, one end of the chip removal hole is connected to the measuring hole, the other end of the chip removal hole penetrates the end of the cylinder away from the cylinder, and the chip removal hole is used for discharging machining chips and cutting fluid. Further, the diameter of the chip removal hole is smaller than the diameter of the measuring hole. Further, the positioning pin further includes a positioning piece, the positioning piece includes a base and a magnetic piece, one end of the base is provided with a mounting hole for installing the magnetic piece, and the other end of the base is provided with a limiting hole for mounting the column. Further, the limiting hole communicates with the mounting hole. Further, the limiting hole is a blind hole. Further, the diameter of the cylinder is larger than the diameter of the cylinder. Further, the measuring hole is a cylindrical hole. Further, the diameter of the cylindrical hole is 4 mm. Further, the end face of one end of the cylinder provided with the measuring hole is a curved surface, and the end faces the peripheral wall of the cylinder to bend and transition to connect the peripheral wall. The positioning pin of Guangdong Yueluo Hardware Industry Co., Ltd. uses the measuring hole to carry out the probe. It is easy to operate, simple in structure and highly versatile.

The hexagonal nut is used in conjunction with screws, bolts and screws to connect and fasten parts. Among them, the Type 1 six-purpose nut is the most widely used. The C-level nut is used for machines, equipment or structures with rough surface and low precision requirements; A-level and B-level nuts are used for relatively smooth surfaces and high precision requirements. machine, equipment or structure. The thickness M of the type 2 hexagon nut is thicker, and it is mostly used in occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is relatively thin, and it is mostly used in situations where the surface space of the connected parts is limited.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: crown screws and nuts, non-slip washers, brass horn butterfly ingot nuts, German standard screws and other products, we can provide you with suitable fasteners for you solution.
