[0032] The bottom protection assembly includes a support box 10, a protection plate 12, a linkage plate 13, a trigger shaft 14 and a sensor 15. A cavity is arranged inside the support box 10. A linkage plate 13 is arranged inside the support box 10. The linkage plate 13 is connected to the protection plate 12. The protection plate 12 is located outside the support box 10. A plurality of trigger shafts 14 are installed on the linkage plate 13. The sensor 15 is connected to the support box 10. The trigger shaft 14 can trigger the sensor 15. The protection plate 14 is preferably a rubber pad. When in use, the support box 10 is connected to the Z-axis drive assembly for the longitudinal movement of the vertical lathe. The sensor 15 is installed on the Z-axis drive assembly for the longitudinal movement of the vertical lathe. The sensor 16 and the sensor 2 15 are both electrically connected to the control system on the lathe, wherein the PLC in the control system is preferably electrically connected to the sensor 16 and the sensor 2 15, and when the sensor 16 and the sensor 2 15 are triggered, the trigger shaft 14 can trigger the sensor 15. The protection plate 14 is preferably a rubber pad. When in use, the support box 10 is connected to the Z-axis drive assembly for the longitudinal movement of the vertical lathe. The sensor 16 and the sensor 2 15 are both electrically connected to the control system on the lathe. 5, it can send a signal to the PLC, and then control the lathe to stop at the moving position to avoid the situation where the collision position continues to move and cause losses. Sensor 1 6 and sensor 2 15 are preferably proximity sensors. When the vertical turning tool 9 is moved, the protective plate 14 protects the lateral area where the turning tool 9 moves, and the protective plate 2 12 protects the bottom area of ​​the turning tool 9. When a collision occurs, the protective plate 4 will be deformed, and the deformation of the protective plate 4 will drive the trigger shaft 5 to move, so that the trigger shaft 5 can trigger the sensor 6, and when the bottom hits an external object, the protective plate 2 12, the linkage plate 13 and the trigger shaft 2 14 will move, and the trigger shaft 2 14 will trigger the sensor 2 15, which is conducive to automatically judging the occurrence of a collision and reducing damage to the tool holder. The corresponding sensors 1 6 and 2 15 can be triggered by the protective plate 1 4 and the protective plate 2 12, thereby improving the safety of use when the tool holder is moving.

[0033] Reference Figure 3 and 5 The tool support assembly includes a positioning seat 7, a support seat 8 and a turning tool 9. The protective frame 1 is mounted on the outside of the support seat 8, and the support seat 8 is connected to the moving end of the vertical lathe. A T-block is arranged on the positioning seat 7, and the positioning seat 7 and the T-block are fixedly connected or connected by screws. A T-slot corresponding to the T-block on the positioning seat 7 is arranged on the support seat 8, and a groove for installing the turning tool 9 is arranged on the positioning seat 7. A plurality of screws for limiting the position of the turning tool 9 are connected to the positioning seat 7. The vertical lathe has a driving assembly that moves left and right and a driving assembly that moves up and down, which can be assembled with a linear module. Through the connection method of the T-block between the positioning seat 7 and the support seat 8, when in use, the position of the turning tool 9 is limited by friction. After a large impact, the positioning seat 7 and the support seat 8 can be offset, and the turning tool 9 and the positioning seat 7 can be offset, thereby improving the protection effect, replacing a relatively fixed installation method, which is beneficial to the protection effect at the turning tool 9.

[0034] Reference Figure 3 and10 The lateral protection component also includes an extension support ring 2 and a flexible pad 3. The extension support ring 2 is connected to the protection frame 1. The protection plate 4 and the extension support ring 2 are connected through the flexible pad 3. The flexible pad 3 is elastic.

[0035] Reference Fig. 9 The bottom protection component also includes a positioning shaft 11. A plurality of positioning shafts 11 are connected to the protection plate 12. The positioning shafts 11 are arranged in parallel. The positioning shafts 11 pass through the side wall of the support box 10. The linkage plate 13 is located inside the support box 10. The linkage plate 13 is connected to each positioning shaft 11. Through the setting of the positioning shaft 11, the protection plate 12 drives the linkage plate 13 to move effectively. Moreover, the positioning shaft 11 passes through the side wall of the support box 10, which is conducive to guiding the moving position of the protection plate 12, the positioning shaft 11 and the linkage plate 13.

[0036] Reference Figure 7 The bottom protection component also includes a spring 16. A plurality of springs 16 are arranged inside the support box 10. The spring 16 is connected to one end of the linkage plate 13. The spring 16 is located on the end of the linkage plate 13 that is opposite to the positioning shaft 11. Through the setting of the spring 16, when the linkage plate 13 moves, it can squeeze the spring 16, thereby facilitating the positioning of the linkage plate 13, the positioning shaft 11 and the moving position of the protection plate 12. Moreover, through the buffering effect of the spring 16, after squeezing the spring 16, some space is provided to reduce the collision between the trigger shaft 14 and the sensor 15.
