[0002] Parts need to be fixed during the processing. Currently, the commonly used devices for fixing pin-type parts are as follows:

[0003] 1. Three-jaw chuck: For a pin with a moderate diameter, you can directly use a three-jaw chuck to clamp one or both ends, adjust the position of the jaws so that the axis of the pin is coaxial with the machine tool spindle, then tighten the jaws and fix the pin with the clamping force of the chuck.

[0004] 2. Mandrel positioning: If there is a through hole in the pin, a special mandrel can be designed to be inserted into the hole, and it can be positioned by the mandrel and fixed to the machine tool spindle with the help of jackscrews, expansion sleeves, etc.

[0005] 3. Magnetic suction cup: For magnetic pins, you can use a magnetic suction cup to directly adsorb and fix them. Adjust the position of the suction cup so that it is in close contact with the surface of the pin, and use the strong magnetic force to firmly fix the pin on the workbench.

[0006] Although the above-mentioned fixing devices can fix pin-type parts, they still have the following disadvantages: 1. Only one part can be installed on a three-jaw chuck or spindle, resulting in low processing efficiency; 2. The magnetic suction cup basically ensures magnetism by turning on and off the power, which consumes a lot of power and increases the processing cost.

[0031] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0032] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0033] The terms such as "upper", "lower", "left", "right" and so on used in this application to indicate positions are usually used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be considered as the scope of this application.

[0034] This application provides a track pin milling tool, see Figure 1 The tooling includes a processing base 1, on which one or more workstations are arranged, and each workstation is provided with a vertical fixing mechanism 5, which is used to press and fix the track pin 11 placed on the workstation. Each workstation includes an open processing groove opened on the surface of the processing base 1, and the open processing groove is a through groove with openings at both ends. A baffle plate 2 is provided at an opening at one end of the open processing groove, and a mounting rod 3 is provided on the baffle plate 2. The vertical fixing mechanism 5 is installed on the mounting rod 3, and the mounting rod 3 is horizontally arranged along the open processing groove. The mounting rod 3 divides the open processing groove into two mounting grooves 4 for mounting the track pin 11 to be processed. When the track pin 11 is placed in the mounting groove 4, one end of the track pin 11 abuts against the baffle plate 2, and the baffle plate 2 plays a role in positioning the track pin 11, such as Figure 5In this application, see Figure 1 The vertical fixing mechanism 5 installed on the mounting rod 3 mainly includes a fixing seat 6, a screw rod 7, a clamping block 8 and a locking nut 9. The fixing seat 6 is installed on the mounting rod 3, and the screw rod 7 is vertically arranged. One end of the screw rod 7 is connected to the fixing seat 6, and the other end is threadedly connected to the locking nut 9. The clamping block 8 is installed on the screw rod 7 and is located below the locking nut 9. Under the action of the locking nut 9, the clamping block 8 clamps and fixes the two track pins 11 in the two mounting grooves 4 on a workstation. The clamping block 8 is a long strip block whose length direction is perpendicular to the length direction of the track pin 11. The length of the clamping block 8 is the same as the width of the open processing groove.

[0035] Therefore, in the present application, multiple workstations are set on a processing base 1, and two installation grooves 4 for installing track pins 11 are formed on each workstation. The vertical fixing mechanism 5 on the workstation can simultaneously press and fix the two track pins 11 installed on the workstation, thereby improving the fixing efficiency of the workpiece and further improving the processing efficiency of the workpiece.

[0036] In one embodiment, see Figure 3 The vertical fixing mechanism 5 in the present application also includes a spring 10, which is sleeved on the screw rod 7 so that the spring 10 is located between the clamping block 8 and the fixing seat 6. When the workpiece is clamped by the clamping block 8, the spring 10 is compressed. When the workpiece is processed and to be removed, the locking nut 9 is adjusted to release the clamping block 8, and the clamping block 8 is automatically lifted by the spring 10, which facilitates the removal of the workpiece, improves the efficiency of replacing the workpiece during the processing, and thus improves the processing efficiency.

[0037] In one embodiment, the mounting rod 3 used to install the vertical fixing mechanism 5 in the present application is in contact with the bottom of the open processing groove, that is, the mounting rod 3 is horizontally placed at the bottom of the open processing groove and the end of the mounting rod 3 is connected and fixed to the baffle 2. The baffle 2 is vertically arranged at one end of the open processing groove, the length direction of the mounting rod 3 is the same as the length direction of the open processing groove, and one end of the mounting rod 3 is connected and fixed to the middle of the baffle 2, so that the mounting rod 3 divides the open processing groove into two long strip mounting grooves 4 of the same size.

[0038] In one embodiment, the two sides of the mounting rod 3 correspond to the two side walls of the open machining groove to form two mounting grooves 4 for mounting the track pin 11. The cross-sectional shape of the mounting groove 4 can be V-shaped, trapezoidal, semicircular, etc. In a specific application example, the shape of the side wall of the mounting rod 3 and the open machining groove can be adapted to the target size and shape of the mounting groove 4. For example, the cross-sectional shape of the mounting groove 4 is designed to be semicircular, the side wall shape of the open machining groove can be set to an arc surface, and the surface of the mounting rod 3 facing the side wall is also set to an arc surface, and the two arc surface side walls are relatively arranged to form a semicircular groove adapted to the size of the track pin 11.

[0039] In one embodiment, the processing base 1 is in the shape of a rectangular parallelepiped, and a plurality of workstations are arranged at intervals on the upper surface of the processing base 1. The plurality of workstations are arranged along the length direction of the processing base 1. The length direction of the open processing groove on each workstation is parallel to the width direction of the processing base 1. The open processing groove is a through groove arranged on the upper surface of the processing base 1. A baffle 2 is arranged at the opening at one end of the open processing groove. One end of the track pin 11 is in contact with the baffle 2, and the other end extends outward from the other end opening of the open processing groove, and the extended part is convenient for taking and placing.

[0040] In one embodiment, a connection seat for adapting and connecting with a machine tool is provided on the processing base 1. For example, positioning grooves are respectively provided at the left and right ends of the processing base 1. When the processing base 1 is installed and fixed with the machine tool, the positioning grooves can assist the processing base 1 in limiting installation. Of course, in other embodiments, the connection seat on the processing base 1 can also be a protrusion, a through hole, a bolt, etc. provided on the processing base 1. The purpose of providing the connection seat is to achieve the installation and fixation of the processing base 1 with the machine tool. Therefore, the structure and position of the connection seat of the processing base 1 can be adapted according to the connection structure on the machine tool.

[0041] In summary, the processing base in the present application is provided with multiple workstations, and each workstation is provided with two installation grooves for installing track pins. During processing, multiple track pins can be fixedly installed on the processing base, and the tool on the machine tool can mill grooves for multiple track pins at the same time, thereby improving processing efficiency.
