[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a CNC machine tool tool setting device, including a worktable 1. An electric push rod 2 is fixedly installed on the top of the worktable 1. A tool 4 is installed on the telescopic end of the electric push rod 2 through a connecting mechanism. A movable seat 6 is provided on the bottom upper surface of the worktable 1 at a position opposite to the tool 4. A groove 11 is opened inside the movable seat 6. The middle part of the upper surface of the groove 11 is open. Multiple pressure sensors 15 are provided on the bottom surface of the groove 11. Multiple pressure plates 12 are provided on the top of the groove 11. The pressure plates 12 are arranged one-to-one with the pressure sensors 15. All pressure plates 12 are installed inside the groove 11 through an elastic support mechanism.

[0018] Furthermore, the elastic support mechanism includes vertical rods 13 that are slidably inserted into both sides of the pressure plate 12. The vertical rods 13 are fixedly installed inside the groove 11. Support springs 14 are sleeved on the outer surface of each vertical rod 13. The upper end of the support spring 14 is fixedly connected to the pressure plate 12, and the lower end of the support spring 14 is fixedly connected to the inner surface of the groove 11.

[0019] Furthermore, a groove 7 is provided on the inner surface of the workbench 1, and a connecting rod 9 is fixedly connected to the inner surface of the groove 7. A sliding groove 8 is provided on the inner surface of the movable seat 6, and one end of the connecting rod 9 is slidably installed inside the sliding groove 8.

[0020] Furthermore, a connecting spring 10 is fixedly connected to the inner surface of the slide 8, one end of the connecting spring 10 is fixedly connected to the connecting rod 9, a handle 16 is fixedly connected to the outer surface of the movable seat 6, a plug plate 17 is inserted into the middle of the handle 16, and a slot adapted to the plug plate 17 is opened on the surface of the worktable 1, so that the plug plate 17 can be moved into or out of the slot.

[0021] Furthermore, the telescopic end of the electric push rod 2 is fixedly connected to a fixed base 3, and connecting bolts 5 are inserted at the four corners of the cutter 4. The cutter 4 is connected to the fixed base 3 through the connecting bolts 5.

[0022] In this embodiment, the operator uses connecting bolts 5 to install the cutter 4 on the fixed base 3, then moves the movable base 6 out of the groove 7 and inserts the insert plate 17 into the slot to fix the movable base 6. Then, the electric push rod 2 is used to drive the fixed base 3 and the cutter 4 to move down. The cutter 4 drives each group of pressure plates 12 to move down. The pressure plates 12 generate pressure on the pressure sensors 15. When the cutter 4 is horizontal, the pressure readings of each group of pressure sensors 15 are the same. When the cutter 4 is tilted, the readings of each group of pressure sensors 15 are different. At this time, the operator needs to reinstall the cutter 4 and straighten the cutter 4.
