At present, in processes such as injection molding, stamping, and testing, products usually use pins to position them on the mounting plate or positioning plate. The general pin positioning method uses cylindrical pins with the same cross-sectional diameter for positioning. Due to the high possibility of product deformation during processing, the pin positioning hole on the product also deforms. Using this type of pin for positioning often causes the pin to jam the product, making it inconvenient to retrieve and place the workpiece, resulting in the pin being broken or the product being scratched or even damaged, with obvious defects.

In use, installation, methods, and principles need to be noted on the production function, and strictly follow the instructions provided on the production function. But it is necessary to use specialized riveting equipment for operation, which is also an indispensable factor to ensure that the riveting nut can maintain stable working performance after installation. During installation, the riveting press and riveting nut should be kept vertically balanced and evenly penetrated downwards. Rivet nut material: 316 stainless steel, 316L stainless steel, 304 stainless steel, carbon steel (du10A), aluminum, copper. The head types of Rivet nut are: flat head, countersunk head, small countersunk head, flat head hexagon, countersunk hexagon. The Rivet nut cylinder can be divided into: round ordinary type, round knurled type, full hexagonal type and half hexagonal type. Hole types of Rivet nut include through hole (open type) and blind hole (closed type). Rivet nut standards include: GB, ANSI, B.S., DIN, UNI, JIS, etc.

The traditional single-sided riveting process mainly adopts two ways of Rivet nut connection and pop rivet connection. The efficiency of Rivet nut is low. If hollow nuts are used, the rigidity is insufficient, resulting in low connection strength; In addition, the anti torsion performance of Rivet nut is low. If the Rivet nut is made into a hexagon for embedding in order to obtain better anti torsion performance, the shape of the sheet metal opening also needs to make a corresponding hexagon, which is inconvenient for processing.

In machine tool processing, it is often necessary to calibrate and debug the probe. The method of using manual correction and detection has low efficiency and unstable accuracy, and in addition, accidents such as collisions may occur. However, calibration tools such as ring gauges are expensive, have a large working range, and have poor universality. Technical implementation elements: Given the above, it is necessary to provide a positioning pin for probe calibration to address the above issues. A positioning pin used for calibrating a probe, which includes a connected column and a column. The column is used for installing on a fixture inside a machine tool, and the end of the column that is away from the column is equipped with a measuring hole to calibrate the probe. Furthermore, the locating pin is also provided with a chip removal hole, one end of which is connected with the measuring hole, the other end of which runs through the end of the cylinder that is away from the cylinder, and the chip removal hole is used to discharge machining chips and Cutting fluid. Furthermore, the diameter of the chip removal hole is smaller than the diameter of the measurement hole. Furthermore, the positioning pin also includes a positioning component, which includes a base and a magnetic component. One end of the base is provided with an installation hole to install the magnetic component, and the other end of the base is provided with a limit hole to install the column. Furthermore, the limit hole is connected to the installation hole. Furthermore, the limit hole is a blind hole. Furthermore, the diameter of the column is greater than the diameter of the column. Furthermore, the measuring hole is a cylindrical hole. Furthermore, the diameter of the cylindrical hole is 4 millimeters. Furthermore, the end face of one end of the column equipped with the measuring hole is a curved surface, and the end face bends and transitions towards the circumferential wall of the column to connect the positioning pin of Guangdong Yueluo Hardware Industry Co., Ltd. with the measuring hole

In the riveting operation, the pull rivet used consists of a mandrel and a deformation collar. When used, drill through holes on the two components to be connected, then pass the head of the pull rivet through the through hole. Use the rivet to clamp the tail of the pull rivet to break it, leaving the head of the pull rivet and the deformation collar in the through hole. The entire riveting process is completed. The existing rivets have the following drawbacks: firstly, the connection between the rivets and the two components cannot be completely tightly fitted, which does not meet the sealing requirements for components with waterproof and leak proof requirements; Secondly, the separation groove of the existing rivet core shaft is close to its head. During the riveting process, when the core shaft is pulled off by the rivet, basically only the head of the core shaft remains in the deformation sleeve ring, and the connection between the two components relies on the compressive stress of the deformation sleeve ring. At this time, the internal part of the deformation sleeve ring becomes hollow due to the core shaft being pulled off, and cannot withstand significant shear stress.
