[0017] The specific implementation of the utility model is as follows: Figure 1 , Figure 2 , Figure 3As shown, a linear rail cutting auxiliary tool includes a bracket 101, which is connected to the workbench of a linear cutting machine tool, and also includes a base plate 102, a pressure block 104, and a tool block 105. The base plate 102 is installed on the top of the bracket 101 and is detachably connected to the bracket 101. The top surface of the base plate 102 has two groups of linear rail grooves 1021 in the length direction for placing linear rails. A pressure block guide groove 1022 is provided on one side of the linear rail groove 1021. The bottom surface of the pressure block guide groove 1022 is lower than the bottom surface of the linear rail groove 1021. Threaded holes 1023 are provided on the top surfaces of the linear rail groove 1021 and the pressure block guide groove 1022. A pressure block 104 is connected to the pressure block guide groove 1022 through a screw and a threaded hole 1023. The pressure block 104 is used to clamp the linear rail. A tool groove 103 is provided in the center of the base plate 102, and a tool block 105 is provided on the edge of the tool groove 103. When in use, the linear rail 201 is pressed against the top surface of the linear rail groove 1021 by a screw. At the same time, the screw of the pressing block 104 is tightened to ensure that the linear rail 201 will not swing in the horizontal direction during the cutting process, thereby improving the end surface quality of the linear rail 201. There is a knife groove 103 in the center of the bottom plate 102 to avoid the electrode wire, and there is a tool setting block 105 on the edge of the knife groove 103 to improve the tool setting efficiency and the cutting efficiency of the linear rail 201.

[0020] Specifically, the bottom plate 102 has a length of 3050 mm and a thickness of 30 mm. The bottom plate 102 of the size can meet the needs of various linear rail 201 cutting operations of machine tool manufacturers, and has strong adaptability.
[0021] Specifically, Figure 1 As shown, the bottom plate 102 is formed by casting or thick plate processing and hollowing. The bottom plate 102 processed by the above process has a balance between weight and bending resistance, which can reduce the weight of the auxiliary tool and facilitate the operator to disassemble and assemble the fixture.
