[0016] First, let me explain the design intention of this utility model. Existing fixtures cannot guarantee the accuracy and stability of the positioning of the cutter head and the tool holder, thus failing to guarantee the assembly precision of the cutter head, which in turn affects the assembly efficiency of the cutter head and the tool holder. Therefore, this utility model designs a high-precision universal positioning fixture for tool assembly.

[0017] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1-2 As shown, the high-precision tool assembly universal positioning fixture includes a main mounting component 1. The main mounting component 1 will be described in detail below. The main mounting component 1 includes a main mounting plate 7, on which several sets of tool holder limiting components 2 are provided.

[0018] To facilitate the limiting of the tool holder, several sets of tool holder limiting components 2 are provided on the main mounting component 1. The limiting of the tool holder 12 will be described in detail below. The tool holder limiting component 2 includes tool holder limiting posts 8 provided on the main mounting component 1. The number of tool holder limiting posts 8 in each set of tool holder limiting components 2 is 2.

[0019] To facilitate the storage of the tool holder 12, a tool holder storage component 3 is provided on the main mounting component 1 between two adjacent sets of tool holder limiting components 2. The tool holder storage component 3 will be described in detail below. The tool holder storage component 3 includes a tool holder storage slot 9 provided on the main mounting component 1 between two adjacent sets of tool holder limiting components 2.

[0020] A cutting head 4 is provided on one side of the tool holder 12 on the main mounting assembly 1. In order to facilitate the positioning of one end of the tool holder 12, an auxiliary positioning assembly 5 is provided on the main mounting assembly 1 on the side of the tool holder away from the cutting head 4. The auxiliary positioning assembly 5 will be described in detail below. The auxiliary positioning assembly 5 includes an auxiliary positioning post 10 provided on the main mounting assembly 1 on the side of the tool holder 12 away from the cutting head 4.

[0021] To facilitate the elastic positioning of the cutter head 4 and to ensure that the cutter head 4 is constantly pushed and tightened during the assembly process, an elastic positioning component 6 for the cutter head 4 is provided on one side of the cutter head 4 on the main mounting component 1. The elastic positioning component 6 for the cutter head 4 will be described in detail below. The elastic positioning component for the cutter head 4 includes an elastic universal positioning post 11 for the cutter head 4 located on one side of the cutter head 4 on the main mounting component 1.

[0022] The specific structure of this utility model has been described in detail above. The working principle of this utility model will be explained below: The tool holder 12 is placed in the tool holder storage slot 9. The two sides of the tool holder 12 are limited by two sets of tool holder limiting components 2. One end of the tool holder 12 is positioned by the auxiliary positioning post 10. Then, the tool head 4 is placed on one side of the tool holder 12. One side of the tool head 4 is constantly pushed by the tool head elastic universal positioning post 11. Then, the tool holder and the tool head 4 are bonded by high viscosity adhesive. Through the tool head elastic universal positioning post 11, it is ensured that the tool head 4 and the tool holder 12 are pushed by a constant force at all times during the adhesive curing process. The high-precision tool assembly universal positioning fixture of this technical solution has a clever structural design, strong practicality, convenient operation, and high positioning accuracy. By using this positioning fixture, the pushing force is maintained during the assembly of the tool holder 12 and the tool head 4, ensuring that the tool head 4 and the tool holder 12 are pushed by a constant force at all times during the adhesive curing process, effectively ensuring the positioning stability of the tool head 4 and the tool holder 12, and also improving the assembly efficiency of the tool head 4 and the tool holder 12.
