[0002] Through hole is a common hole type. It is a hole drilled directly through and can pass through. Through holes also include oblique through holes. The depth of the oblique through hole may affect the quality of the product. When assembling parts, the depth of the through hole needs to have an accurate value to avoid affecting the assembly of parts. Therefore, an oblique through hole depth gauge is needed.

[0003] Traditional oblique through-hole inspection fixtures usually require workers to manually measure the through-hole depth. In addition, because traditional through-hole inspection fixtures require workers to manually measure, their error values ​​may be large and cannot be applied to high-precision usage scenarios. Manual inspection will make it difficult to cope with large-scale inspection work, so improvements are needed. Utility Model Content

[0005] A detection position adjustment mechanism is arranged on the top of the outer frame, and the detection position adjustment mechanism comprises a groove. The outer wall of the outer frame is arranged with a groove, and a motor is fixedly connected to the inner wall of the groove. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling.

[0006] Preferably, a ball screw is fixedly connected to the outer wall of the rotating shaft, and a ball nut is cooperatively mounted on the outer wall of the ball screw.

[0007] Through the connection between the ball screw and the ball nut, the ball nut can be easily rotated.

[0008] Preferably, a connecting block is fixedly connected to the top of the ball nut, and an electric push rod is fixedly connected to the outer wall of the connecting block.

[0009] Through the connection between the ball nut and the connecting block, the connecting block can be easily moved.

[0010] Preferably, the other end of the electric push rod is fixedly connected to an electric turntable, the outer wall of the electric turntable is fixedly connected to a laser rangefinder, and the outer wall of the laser rangefinder is fixedly connected to a camera assembly.

[0011] By connecting the electric turntable and the laser rangefinder, the laser rangefinder can be conveniently rotated.

[0012] Preferably, the outer wall of the outer frame is provided with an oblique through-hole angle confirmation mechanism, the oblique through-hole angle confirmation mechanism includes an angle sensor, and the outer wall of the outer frame is fixedly connected with the angle sensor.

[0013] By connecting the outer frame and the angle sensor, the inclination angle of the oblique through hole can be conveniently detected.

[0016] Preferably, a mounting shell is fixedly connected to the outer wall of the connecting column, and a detection rod is cooperatively mounted on the inner wall of the mounting shell.

[0017] The detection rod can be easily disassembled by connecting the mounting shell and the detection rod.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model achieves the effect of rapid detection of the depth of the oblique through-hole by setting the detection position adjustment mechanism. First, the electric turntable will rotate the laser rangefinder to an angle consistent with the through-hole depth angle through the angle value transmitted by the oblique through-hole angle confirmation mechanism. It should be noted here that the detection angle of the laser rangefinder is vertically downward, and then the camera assembly is used in conjunction with the algorithm to confirm the center point of the through-hole surface. After confirming the center point, the motor is used to drive the shaft to rotate, so that the ball nut drives the connecting block and the laser rangefinder to move forward and backward. At the same time, the electric push rod will push the angle sensor to a suitable position. The two cooperate with each other, and the laser emitted by the laser rangefinder can be injected from the center point of the through-hole. Therefore, through the design of the above functions, the angle of the laser emitted by the laser rangefinder is consistent with the oblique through-hole angle, and the injection position of the laser rangefinder is consistent with the center point of the through-hole, so the depth of the through-hole can be conveniently detected. Through the design of the inspection tool, not only the effect of rapid detection of the depth of the oblique through-hole is achieved, but also the detection error of the inspection tool is small, which is suitable for high-precision detection work.

[0020] 2. The utility model achieves the effect of confirming the inclination angle of the oblique through hole to cooperate with the detection depth by setting the oblique through hole angle confirmation mechanism. After placing the outer frame in a suitable position, the detection rod is inserted into the mounting shell, and then the detection rod is inserted into the through hole. Then, by moving the outer frame and rotating the detection rod, the outer wall of the detection rod is completely fitted with the inner wall of the oblique through hole, so the inclination angle of the inner wall of the oblique through hole can be obtained. Through the design of this function, the inclination angle of the oblique through hole can be conveniently confirmed. After confirming the through hole angle, the through hole depth can be continuously detected in cooperation with the detection position adjustment mechanism. Due to the particularity of the oblique through hole, if the depth of the oblique through hole is detected, the laser angle emitted by the laser rangefinder must be consistent with the depth of the oblique through hole, and then the mechanism and the detection position adjustment mechanism cooperate with each other, and the two complement each other to form a new and efficient oblique through hole depth inspection tool.
