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.

Hex cap screw and Hex bolt Hex bolt As the name suggests, it is a male threaded fastener with a hexagonal head, designed to be turned with a wrench. According to the ASME B18.2.1 standard, the head height and shank length tolerance of the hexagon head screw (Hex cap screw) is smaller than that of the general large hexagon bolt (Hex bolt), so ASME B18.2.1 hexagon screw is suitable for installation in all hexagon bolts that can be used. places, also including places where the large hex bolts are too large to be used. The screw head of the hexagon socket screw is round on the outside, and the middle is a concave hexagon, and the hexagon screw is the kind of common hexagonal screw head. The hexagon socket head screwdriver looks like a '7'. Cut two sections of a hexagonal steel bar and bend it at 90 degrees to form a hexagon socket head screw wrench, which is sold in hardware tool stores. Hexagon socket screwdrivers are not so-called mobile phone special screwdrivers. Mobile phone special screwdrivers can be bought at the booths that sell repair tools in the electronics market. Hexagon socket head cap screws are often used in machinery, mainly because they are easy to fasten, disassemble, and not easy to slip. The Allen wrench is generally a 90° bend. One end of the bend is long and one side is short. When using the short side to drive screws, holding the long side can save a lot of force and tighten the screws better. The long end has a round head (a hexagonal cylinder is similar to a sphere) and a flat head. The round head can be easily slanted and disassembled, and some parts that are inconvenient to lower the wrench can be installed. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. Its advantages are that the screw head (the force position of the wrench) is thinner than the inner hexagon, and some places cannot be replaced by the inner hexagon. In addition, machines with low cost, low power strength and low precision requirements use much less hexagon socket screws than external hexagon screws. [1] Socket cap screw, also known as socket head screw or Allen bolt, is a screw with a hexagonal inner hole on the head, with a hexagonal ruler (hex key, Allen wrench or Allen key) Tighten or loosen only after inserting into the inner hole. The most commonly used hexagon socket head screws are cylindrical head screws with a head diameter of about 1.5 times the main diameter of the thread (1960 series). Countersunk head cap screw. The countersunk hole design allows the screw head to be rotated without being exposed on the surface of the fixed object, so it is mostly used in places where the surface is small and it is inconvenient for traditional wrenches to use.

The lifting ring nut is a part that tightly connects the mechanical equipment. It can be connected together through the inner thread, the lifting ring nut and the screw of the same specification. Lifting ring nuts are often used in conjunction with externally threaded columns to lift various equipment, such as molds, chassis, motors, etc.

A rivet is a nail-shaped object with a cap on one end: in riveting, the parts being riveted are joined by their own deformation or by interference. There are many types of rivets, and they are informal. However, the two ends of conventional rivets are concentric, which is not suitable for special occasions.

Screw, some people call it screw [Screw] (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called wood screws to fasten wooden and plastic parts. The screw rod is a machine screw (machine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts. With the development of society, the materials for making screws are also various, and the functions of screws are becoming more and more diverse.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: trademark nameplate rivets, carbon steel cap nuts, auto repair expansion screws, open wire screws and other products, we can provide you with suitable products for you. Fastener Solutions.
