It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] The utility model provides a hole depth detection device, including a work seat 1, a cavity 101 is provided in the work seat 1, a motor 102 is installed in the cavity 101, the motor 102 is rotatably connected to a rotor 103, a base 104 is installed on the rotor 103, a stand 105 is installed on the work seat 1, a fixed block 2 is installed on the stand 105, a measuring rod 3 is slidably connected to the fixed block 2, a limit frame 4 is installed at a position below the fixed block 2 on the stand 105, the measuring rod 3 is slidably inserted into the limit frame 4, and the base The seat 104 is evenly distributed with positioning seats 106, and the product to be tested 107 is installed in the positioning seats 106. The end of the measuring rod 3 is a spherical bump 301, and the bottom of the spherical bump 301 is tangent to the upper end surface of the product to be tested 107. The limiting frame 4 is provided with a slide groove 401. The measuring rod 3 is fixedly connected to a shift block 402. The limiting frame 4 is sleeved with a clamping frame 403. The top of the clamping frame 403 is against the shift block 402. The fixed block 2 is fixedly connected to the scale plate 5. The design of the scale plate 5 structure makes it easy for staff to observe;

[0018] When the hole depth detection device is actually used, the size of the bracket 403 is selected according to the relative height of the required product 107 to be tested, and the position of the spherical bump 301 at the end of the measuring rod 3 is adjusted so that the relative position of the end of the spherical bump 301 and the end surface of the product 107 to be tested are always in a tangent state. Since the products to be tested are of the same series in batches, the relative position of the bracket 403 and the measuring rod 3 is reset after measuring one product 107 to be tested. When the product 107 to be tested is moved to the position directly below the measuring rod 3, the relative position of the bracket 403 and the measuring rod 3 is reset. When the measuring rod 3 is in the position of the fixed block 2, the staff takes out the bracket 403 and operates the dial block 402 to drive the measuring rod 3 to slide in the limit frame 4 until the spherical protrusion 301 at the end of the measuring rod 3 abuts against the bottom wall of the hole. At this time, the measuring rod 3 makes an adaptive change in its relative position on the fixed block 2. The value of the hole depth of the product 107 to be tested is read according to the scale on the measuring rod 3 relative to the scale plate 5. The staff then compares the value with the required value to determine whether it is qualified. Then the motor 102 is driven to drive the base 104 on the rotor 103 to rotate, so that the lower After the inspection is completed, the relative position of the measuring rod 3 is reset, and then the motor 102 drives the rotor 103 to drive the relative position of the product 107 to be inspected on the base 104 to adjust the relative position of the product 107 to be inspected, thereby realizing the semi-automatic measurement of the product 107 to be inspected. Compared with the conventional manual measurement method of random sampling, the technical solution adopted by the utility model can inspect a large number of products 107 to be inspected, realizes semi-automatic production and processing, liberates the labor intensity of the staff, and has a compact overall structure and is easy to install and maintain.

[0019] like Figure 1-2 As shown, the bracket 403 is detachably connected to the limiting bracket 4, and the size of the bracket 403 is adaptively adjusted according to actual conditions.

[0020] The effect achieved by the entire embodiment 1 is that, during use, the size of the corresponding card holder 403 is adjusted according to the actual size of the product to be tested 107 .

[0021] Working principle: According to the relative height of the required product to be tested, the corresponding card holder size is selected, and the position of the spherical bump at the end of the measuring rod is adjusted so that the relative position of the end of the spherical bump is always tangent to the end face position of the product to be tested. Since the products tested are in batches of the same series, the relative position of the card holder and the measuring rod is reset after measuring one product to be tested. When the product to be tested moves to the position directly below the measuring rod, the staff takes out the card holder and operates the dial block to drive the measuring rod to slide in the limit frame until the spherical bump structure at the end of the measuring rod abuts against the bottom wall of the hole. At this time, the relative position of the measuring rod on the fixed block makes an adaptive change, and the value of the hole depth of the product to be tested is read according to the scale on the scale plate relative to the measuring rod. The staff then compares it with the required value to determine whether it is qualified, and then drives the motor to drive the base on the rotor to rotate, so that the next product to be tested moves to the position below the measuring rod. At this time, the measuring rod has been reset on the stand before moving, and the above completes the measurement of the aperture of the product to be tested.
