[0023] As Figures 2-3As shown in the figure, the lifting assembly includes a mounting bracket 412. A bidirectional lead screw 411 is installed inside the mounting bracket 412. A turntable 413 is installed at the front end of the bidirectional lead screw 411. Moving blocks 410 are respectively installed on the outer sides of the bidirectional lead screw 411 near both ends. A connecting rod 409 is installed on the side wall of the moving block 410. The upper end of the connecting rod 409 is movably connected to the mounting plate 401. Rotating the turntable 413 forward drives the bidirectional lead screw 411 to rotate. The bidirectional lead screw 411 drives the moving blocks 410 to move. The moving blocks 410 cooperate with the connecting rod 409 to drive the mounting plate 401 to descend. Reversing drives the mounting plate 401 to ascend.

[0024] As Figure 4 shown in the figure, limit bars 407 are respectively installed at the front and rear ends of the rack 406. The side wall of the limit bar 407 is designed to be arc-shaped.

[0028] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art to those skilled in the art.

[0029] The implementation principle of the simple numerical control machine tool tool setting and measuring instrument in the embodiment of the present application is as follows:

[0030] When the digital display height gauge is not working, the installation housing 403 and the fixing strip 404 are in a high position. Install the cutting tool of the CNC milling machine tool holder on the installation tube 3. The installation end of the cutting tool of the CNC milling machine tool holder extends into the through hole opened in the central vertical end of the installation tube 3 for installation. Manually move one of the fixing strips 404 close to the cutting tool of the CNC milling machine tool holder. During the movement of the fixing strip 404, the installation housing 403 limits its position. The other fixing strip 404 moves through the cooperation of the rack 406 and the gear 408. The two fixing strips 404 approach the cutting tool of the CNC milling machine tool holder and contact it. Rotate the turntable 413 clockwise to drive the bidirectional lead screw 411 to rotate, and then push the moving block 410 through threaded connection. The moving block 410 pushes the connecting rod 409 to drive the mounting plate 401 to descend. This movement causes the mounting plate 401, the support rod 402, the installation housing 403 and the fixing strip 404 to descend as a whole until the fixing strip 404 is in close contact with the boss on the outer side of the cutting tool of the CNC milling machine tool holder, realizing the precise fixation of the cutting tool of the CNC milling machine tool holder. During the descent, the rack 406 cooperates with the arc-shaped side wall of the limiting strip 407, and through the limiting effect of the connecting groove 405, the stability of the rack 406 in the horizontal direction is ensured. After the cutting tool of the CNC milling machine tool holder is fixed, the digital display height gauge 2 can be used for tool setting and measurement. After the measurement is completed, rotate the turntable 413 counterclockwise to make the lifting assembly drive the mounting plate 401, the support rod 402, the installation housing 403 and the fixing strip 404 to rise, releasing the cutting tool of the CNC milling machine tool holder and completing the entire measurement process.
