[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0020] refer to Figure 1 、 2 As shown, the utility model provides a measuring instrument for detecting the outer ring hole of a gearbox housing, comprising a detection platform 3, the detection platform 3 being provided with a positioning shaft 31, the gearbox housing 1 being hollow cylindrical, with a center hole 11 being provided at the center of the top surface, the gearbox housing 1 being rotatably sleeved on the positioning shaft 31 through the center hole 11, and thus placed on the detection platform 3; and further comprising a detection module 2, the detection module 2 being evenly circumferentially arranged on the detection platform 3 with the positioning shaft 31 as the center of the circle;
[0021] Specifically, the gearbox housing 1 is evenly provided with housing through holes 12 around it, and the housing through holes 12 are rectangular; the detection module 2 includes a handle 21, one end of the handle 21 is connected to a connecting shaft 22, and the connecting shaft 22 is movably arranged along the axis and penetrates the fixing seat 23, and the end of the connecting shaft 22 away from the handle 21 and passing through the fixing seat 23 is a measuring pin 221, and the measuring pin 221 is a rectangular parallelepiped, and the outer circumference of the measuring pin 221 is consistent with the inner circumference of the housing through hole 12. The position of the measuring pin 221 of each evenly arranged detection module 2 corresponds to the position of the housing through hole 12; pushing the handle 21 drives the measuring pin 221 to move forward, so that the measuring pin 221 can be inserted into the housing through hole 12;
[0022] The fixing seat 23 is symmetrically provided with positioning bases 231 on both sides parallel to the connecting shaft 22. The positioning bases 231 are provided with bolt holes. The fixing seat 23 is fixed on the detection platform 3 by bolts.
[0023] The working principle and beneficial effects are as follows: push the handle 21 on each detection module 2 forward so that each measuring pin 221 is inserted into the shell through hole 12. If they can be inserted normally and without deviation, rotate the gearbox shell 1 so that the adjacent shell through hole 12 of the detected shell through hole 12 is aligned with the measuring pin 221, and then push the handle 21 on each detection module 2 forward so that each measuring pin 221 is inserted into the shell through hole 12. Repeat the above steps in sequence until each detection module 2 is detected and the measurement process is completed. If each shell through hole 12 can be inserted normally, it means that the product is qualified. If it cannot be inserted normally, it means that the product is unqualified. The detection device has a reasonable structural design, is simple and quick to operate, has high work efficiency, and can ensure detection accuracy.
