Description of the drawings:

[0012] Figure 1 It is a partial structural schematic diagram of the utility model;

[0013] Figure 2 It is a schematic diagram of the local structure of the utility model during detection. Specific implementation method:

[0014] For example, see Figure 1 to Figure 2 As shown, a protective tooling for a wireless automatic probe includes a radio lathe measuring head 10 (which is a mature product that can be directly purchased). A radial extension edge 11 is formed on the middle outer wall of the radio lathe measuring head 10. A measuring rod 12 of the radio lathe measuring head 10 is located at the left end of the radio lathe measuring head 10. An outer protective sleeve 20 is inserted into the left part of the radio lathe measuring head 10. The right end of the outer protective sleeve 20 is close to or close to the left side wall of the radial extension edge 11. A telescopic sleeve 30 is inserted into the left part of the outer protective sleeve 20. The measuring rod 12 is inserted into the telescopic sleeve 30, and the left end probe of the measuring rod 12 is located in the telescopic sleeve 30.

[0015] Further, the middle part of the right end surface of the outer protective sleeve 20 is formed with a main jack 21 extending to the left, the middle part of the left end surface of the main jack 21 is formed with a middle jack 22 extending to the left, and the middle part of the left end surface of the middle jack 22 is formed with a middle through hole 23. The left part of the radio lathe measuring head 10 is inserted into the main jack 21, the outer protective sleeve 20 is fixed in the left part of the radio lathe measuring head 10, the telescopic spring 1 is inserted into the middle jack 22, the telescopic sleeve 30 is inserted into the middle through hole 23, the right end of the telescopic sleeve 30 is in the middle jack 22, and the right end of the telescopic sleeve 30 is inserted into the middle through hole 23. A radially extending limit portion 31 is formed on the side wall, and the left end surface of the radially extending limit portion 31 is pressed against the left end surface of the middle plug hole 22. The measuring rod 12 is inserted into the telescopic spring 1, and the left end of the telescopic spring 1 is forced on the right end surface of the radially extending limit portion 31. The right end of the telescopic spring 1 is forced on the left end surface of the radio lathe measuring head 10. The left end of the telescopic sleeve 30 extends out of the left end surface of the middle through hole 23, and the left end probe of the measuring rod 12 extends out of the left end of the middle through hole 23 and is located in the left end of the telescopic sleeve 30 (the outer side wall of the telescopic spring 1 is in close contact with the inner side wall of the middle through hole 23).

[0016] Furthermore, the upper and lower parts of the side wall of the right part of the outer protective sleeve 20 are formed with screw-in holes 24, and the screw-in holes 24 correspond to the corresponding positioning recessed holes 13 formed on the outer side wall at the left side of the radially extending edge 11 of the radio lathe measuring head 10. The screw portion of the bolt can be screwed into the screw-in hole 24, and the end portion thereof extends into the corresponding positioning recessed hole 13, so that the outer protective sleeve 20 will not detach from the radio lathe measuring head 10.

[0017] Further, an annular groove 25 is formed on the middle inner wall of the outer protective sleeve body 20, and a plurality of outer mounting grooves 26 are formed on the middle outer wall of the outer protective sleeve body 20 (in this embodiment, the outer mounting grooves 26 are formed at the upper and lower parts), the outer mounting groove 26 is communicated with the annular groove 25, the distance between the left and right side walls of the outer mounting groove 26 is greater than the distance between the left and right side walls of the annular groove 25, the plastic protective sheet 2 is nested in the outer mounting groove 26 and covers the part of the outer mounting groove 26 facing the annular groove 25, the inner wall surface of the plastic protective sheet 2 is close to the inner wall surface of the edge of the outer mounting groove 26, and a porous annular sleeve 40 is fixed on the middle outer wall of the outer protective sleeve body 20, the outer wall of the plastic protective sheet 2 is close to the inner wall of the porous annular sleeve 40, and the porous annular sleeve 40 covers all the outer mounting grooves 26. The arrangement of the outer mounting groove 26 and the annular groove 25 enables the signal of the radio lathe measuring head 10 to be wirelessly transmitted to prevent shielding.

[0018] Furthermore, a connecting through hole is formed in the middle of the porous annular sleeve 40, and the connecting through hole corresponds to the screw hole 16 formed on the middle side wall of the radio lathe measuring head 10. The screw portion of the fixing bolt 3 is inserted into the connecting through hole and the through hole formed in the middle of the inner side wall of one side of the annular groove 25. The end of the screw portion of the fixing bolt 3 passes through the annular groove 25 and is screwed in the screw hole 16. The inner end surface of the rotating portion of the fixing bolt 3 is pressed against the outer side wall of the porous annular sleeve 40, thereby realizing the fixation of the porous annular sleeve 40, wherein a plurality of through holes are formed on the porous annular sleeve 40.

[0019] In this embodiment, the outer protective sleeve 20, the telescopic sleeve 30, and the porous annular sleeve 40 can all be made of materials such as plastic that do not shield wireless signals.

[0020] When this embodiment is in use, it can reduce the collision of cutting materials and other splashing materials generated by external processing on the measuring rod 12 and the measuring head of the radio lathe measuring head 10 through the outer protective sleeve 20, the telescopic sleeve 30, the porous annular sleeve 40 and the plastic protective sheet 2, thereby reducing the probability of damage, ensuring its service life, reducing the frequency of repair and replacement, and reducing the repair and maintenance costs.

[0021] When this embodiment is in operation, the right part of the radio lathe measuring head 10 is fixed on the moving frame of the machine tool, and moves toward the right end face of the processing equipment through the moving frame, so that the left end face of the telescopic sleeve 30 is first pressed against the right end face of the processing part, and with the movement of the moving frame, the telescopic spring 1 is compressed, so that the telescopic sleeve 30 moves to the right until the measuring head of the measuring rod 12 contacts the right end face of the processing part, and the processing depth or length can be measured, so that the current size of the processing part can be obtained, and its specific processing situation can be obtained. The entire process is protected by the outer protective sleeve 20, the telescopic sleeve 30, the porous annular sleeve 40 and other components to ensure their service life.
