[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figures 1 to 4 An embodiment of this utility model: A testing device for machining machine tool parts includes a main body 3. A connecting block 4 is provided at the upper end of the main body 3. A limiting block 1 for installation and limiting is fixedly connected to the upper end of the connecting block 4. A threaded hole is provided at the lower end of the main body 3, and a connecting post 7 is threadedly connected to the threaded hole. A base plate 8 is provided at the bottom end of the connecting post 7, and an adjustment mechanism is provided in the base plate 8. The limiting block 1 can precisely limit the movement of the parts. A screw 5 is provided at the upper end of the connecting post 7, and the screw 5 is fixedly connected to the connecting post 7. The screw 5 is threadedly connected to the threaded hole at the lower end of the main body 3, and the screw 5 strengthens the connection between the connecting post 7 and the main body 3. For connection stability, both the main body 3 and the screw 5 have corresponding through holes, and a limiting post 6 is provided in the through hole. The limiting post 6 is installed through the through hole, and a nut 2 is provided at one end of the limiting post 6. The limiting post 6 has a threaded groove that is threaded to the nut 2 to prevent loosening during use. The connecting post 7 has a vertical inner hole, and a spring 10 is fixed to the upper wall of the inner hole. A hemispherical block is fixed to the other end of the spring 10. The hemispherical block is fixedly connected to the chassis 8 to show the contact detection status of the connecting post 7. The spring helps to buffer the slight vibration during detection and reduce the error caused by the shaking of the connecting post 7.

[0020] In this invention, the adjustment mechanism consists of a rotating ring 12, multiple extension blocks 9 hinged to the rotating ring 12, and an adjustment assembly. Multiple square holes are equidistantly spaced on the outer wall of the chassis 8. One end of each extension block 9 extends out of the chassis 8 through a square hole. The rotating ring 12 is rotatably mounted in the chassis 8, and a spline is fixed to the lower end of the rotating ring 12. The rotation of the rotating ring 12 can cause the extension blocks 9 to extend and retract, thus expanding the detection length of the chassis 8. The chassis 8 consists of an adjustment mechanism, a fixed ring 11, and a return spring 13. A limiting hole is provided at the lower end of the chassis 8. A limiting groove for a limiting fixing ring 11 is symmetrically provided on the inner wall of the limiting hole. A locking block 14 is symmetrically provided on the outer wall of the fixing ring 11. The locking block 14 is slidably connected to the limiting groove. A fixing hole for fixing the spline is provided at the bottom end of the fixing ring 11. A return spring 13 is abutted at the upper end of the fixing ring 11. The other end of the return spring 13 abuts at the bottom end of the rotating ring 12. The fixing ring 11 and the return spring 13 cooperate to fix the rotating ring 12, ensuring the adjustment stability of the extension block 9.

[0021] Working Principle: When using this invention, the device is fixed on the testing machine tool, and the machine tool parts to be tested are installed and limited by the limiting block 1. According to the testing requirements, the connecting column 7 of the testing machine tool is rotated, and the height of the device is adjusted by the threaded engagement of the screw 5 and the main body 3. After adjustment, the limiting column 6 is inserted into the through hole and the nut 2 is tightened to fix the height. If testing large parts, the fixing ring 11 is pushed upward to compress the return spring 13. The fixing hole of the fixing ring 11 is disengaged from the spline at the lower end of the rotating ring 12. The rotating ring 12 is rotated to drive the extension block 9 to extend from the square hole to expand the testing length of the chassis 8. After adjustment, the fixing ring 11 is released so that it is reset under the action of the return spring 13. During reset, the fixing hole and the spline are reconnected and fixed. During the testing process, the spring 10 and the hemispherical block buffer the vibration and display the contact testing status of the connecting column 7 to ensure the testing accuracy. After the testing is completed, the extension block 9 is retracted in the reverse operation, the nut 2 and the limiting column 6 are loosened, and the device is adjusted to the initial state.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
