It is the main tool for drilling rocks in construction projects in the fields of mining resources exploitation, transportation road construction, hydropower project construction, urbanization construction, etc. At present, a process hole for connecting with the drill rod needs to be opened in the drill bit. The smoothness and verticality of the inner wall after processing are important factors in subsequent production and processing to ensure the accuracy of the thread opening, so the hole needs to be inspected.

[0025] The position of the sensing contact 47 is adjusted by the lifting mechanism 2 and the adjusting mechanism 3 so that the sensing contact 47 can penetrate into the inner wall of the drill hole. Then, the rotating mechanism 4 drives the sensing contact 47 to rotate, thereby detecting the inner wall of the drill hole.

[0026] like Figure 2 , Figure 3 As shown, the outer wall of the fixed box 21 is provided with a scale 22, a motor 23 is fixedly connected to the top of the left fixed box 21, a threaded rod 24 is fixedly connected to the output end of the motor 23, the bottom end of the threaded rod 24 is rotatably connected to the bottom end of the inner cavity of the left fixed box 21, the top of the threaded rod 24 is transmission-connected to a transmission belt 25, the right side of the transmission belt 25 is transmission-connected to a threaded rod 26, one end of the threaded rod 26 is rotatably connected to one end of the inner cavity of the right fixed box 21, the tops of the outer walls of the threaded rods 124 and 26 are both threadedly connected to a slider 27, the outer wall of the slider 27 is slidably connected to the inner wall of the fixed box 21, and the front end of the slider 27 is fixedly connected to the rear end of the fixed frame 31.

[0027] By starting the motor 1 23, the motor 1 23 drives the threaded rod 1 24 to rotate, so that the threaded rod 1 24 drives the transmission belt 25 to rotate synchronously, and the transmission belt 25 drives the threaded rod 2 26 to rotate synchronously, thereby causing the slider 1 27 to slide downward on the outer walls of the threaded rod 1 24 and the threaded rod 2 26, driving the fixed frame 31 to move synchronously.

[0028] like Figure 2 , Figure 3 As shown, the left and right parts of the rear end of the fixed frame 31 are fixedly connected to a fixed plate 32, one end of the fixed plate 32 is fixedly connected to a guide block 33, the outer wall of the guide block 33 is slidably connected to the inner wall of the fixed box 21, the outer shape of the guide block 33 is T-shaped, and the left and right ends of the fixed frame 31 are fixedly connected to pointers 34.

[0029] When the fixed frame 31 moves, it drives the fixed plate 32 to move synchronously, and the fixed plate 32 drives the guide block 33 to slide synchronously on the inner wall of the fixed box 21. The guide block 33 limits the fixed frame 31, so that the fixed frame 31 slides more smoothly. At the same time, the fixed frame 31 drives the pointer 34 to move downward synchronously.

[0030] like Figure 2 , Figure 4 As shown, the left end of the fixed frame 31 is fixedly connected to the motor 2 35, the output end of the motor 2 35 is fixedly connected to the threaded rod 3 36, the right end of the threaded rod 36 is rotatably connected to the right end of the inner cavity of the fixed frame 31, and the outer wall of the threaded rod 36 is threadedly connected to the inner wall of the slider 2 37.

When the induction contact 47 moves to the top of the drill bit hole, the second motor 35 can be turned off.

[0032] like Figure 2 , Figure 5 As shown, the output end of the motor 3 41 is fixedly connected to a rotating rod 42 , the bottom end of the rotating rod 42 is overlapped with a connecting rod 43 , and the bottom of the connecting rod 43 is fixedly connected to an induction contact 47 .

[0033] When the sensing contact 47 extends into the inner wall of the drill bit hole, the motor three 41 is started, and the motor three 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the positioning rod 44 and the connecting rod 43 to rotate synchronously, thereby driving the sensing contact 47 to rotate synchronously, so that the sensing contact 47 detects the drill bit hole. When the sensing contact 47 contacts the rough part of the inner wall of the drill bit hole, the sensing contact 47 sends a feedback to stop the motor three 41 and the motor one 23, and then restart the motor one 23 to reverse, driving the sensing contact 47 away from the inner wall of the drill bit hole. During this process, the scale 22 pointed to by the pointer 34 can be observed to judge the rough position of the inner wall of the drill bit hole, which is convenient for subsequent secondary processing and has the effect of facilitating the judgment of the rough position of the inner wall of the drill bit hole.

[0034] like Figure 2 , Figure 5 As shown, the top end of the connecting rod 43 is fixedly connected with a positioning rod 44, the outer wall of the positioning rod 44 is plugged into the inner wall of the rotating rod 42, the inner walls of the rotating rod 42 and the positioning rod 44 are plugged with a limiting rod 45, the shape of the limiting rod 45 is diamond-shaped, the outer wall of the limiting rod 45 is fixedly connected with a rubber block 46, the outer wall of the rubber block 46 is clamped with the inner wall of the positioning rod 44, and the shape of the rubber block 46 is hemispherical.

[0036] The working principle of the utility model is as follows: when in use, the drill bit to be tested is placed on the bottom plate 1, and then the motor 2 35 is started, and the motor 2 35 drives the threaded rod 3 36 to rotate, so that the slider 2 37 slides on the inner wall of the threaded rod 3 36, and the slider 2 37 drives the motor 3 41 to move synchronously, and the motor 3 41 drives the induction contact 47 to move synchronously. When the induction contact 47 moves to the top of the drill bit hole, the motor 2 35 can be turned off, and then the motor 1 23 is started, and the motor 1 23 drives the threaded rod 1 24 to rotate, so that the threaded rod 1 24 drives the transmission belt 25 synchronously. The transmission belt 25 drives the threaded rod 26 to rotate synchronously, thereby causing the slider 1 27 to slide downward on the outer walls of the threaded rod 1 24 and the threaded rod 26, driving the fixed frame 31 to move synchronously, the fixed frame 31 drives the fixed plate 32 to move synchronously, the fixed plate 32 drives the guide block 33 to slide synchronously on the inner wall of the fixed box 21, and the guide block 33 limits the fixed frame 31, so that the fixed frame 31 slides more smoothly, and at the same time, the fixed frame 31 drives the pointer 34 to move downward synchronously, and the fixed frame 31 drives the induction contact 47 to extend into the drill bit hole. When the induction contact 4 When the drill bit hole is entered, the motor 3 41 is started, and the motor 3 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the positioning rod 44 and the connecting rod 43 to rotate synchronously, thereby driving the sensing contact 47 to rotate synchronously, so that the sensing contact 47 detects the drill bit hole. When the sensing contact 47 contacts the rough part of the inner wall of the drill bit hole, the sensing contact 47 sends feedback to stop the motor 3 41 and the motor 1 23, and then restarts the motor 1 23 to reverse, driving the sensing contact 47 away from the inner wall of the drill bit hole. In this process, the pointer 34 can be observed. The pointed scale 22 is used to judge the position where the inner wall of the drill bit hole is not smooth, which is convenient for subsequent secondary processing. It is convenient to judge the position where the inner wall of the drill bit hole is not smooth. Later, when it is necessary to detect drill bit holes of different diameters, the limit rod 45 is taken out so that the rubber block 46 is no longer plugged into the inner wall of the positioning rod 44, and then the connecting rod 43 is pulled downward so that the outer wall of the positioning rod 44 is no longer plugged into the inner wall of the rotating rod 42. In this way, the connecting rod 43 can be removed and replaced, which is convenient for replacement, thereby greatly improving the user experience.
