[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. However, it is not convenient to measure the radius of the shaft hole of the reducer housing, nor is it convenient to measure the thickness of the shaft hole. Therefore, we propose a reducer housing shaft hole detection device.

[0003] Usually, a caliper is used to detect whether the shaft hole is compliant. The detection process is relatively complicated and requires operators with certain operating experience to complete it. In addition, it is impossible to detect the inner wall deviation range and fluctuation of the shaft hole of the reducer case, which is not conducive to the repair of unqualified products.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a reducer housing shaft hole detection device, which has the following beneficial effects:

[0016] 1. The reducer case shaft hole detection device, by pulling the pulling handle, the pulling handle will drive the inclined slider to move at the same time.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 The utility model provides a new technical solution: a reducer housing shaft hole detection device, comprising a fixed base 1, the upper surface of the fixed base 1 is fixedly connected with two optical axes 2 with certain damping self-fixing properties, the top ends of the two optical axes 2 are fixedly connected with optical axis fixing plates 17, and the fixed base 1 is provided with a shaft hole detection device;

[0024] Further, the shaft hole detection device includes a sliding plate 3, the sliding plate 3 is slidably connected to the outer surfaces of the two optical axes 2, and the center position of the sliding plate 3 is rotatably connected to a rotating sleeve 4;

[0025] Furthermore, a micrometer 5 for displaying detection data is fixedly installed on the outer surface of the rotating sleeve 4, and a fixing seat 6 is fixedly connected to the rear end of the sliding plate 3, and the internal space of the sliding plate 3 and the fixing seat 6 is communicated.

[0026] Furthermore, four fixed shafts 7 are fixedly connected inside the fixed seat 6, and connecting rods 8 are rotatably sleeved on the outer surfaces of the four fixed shafts 7. An inclined slider 11 is slidably connected inside the rotating sleeve 4, and the inclined surface of the inclined slider 11 is adapted to the detection end of the micrometer 5.

[0027] Furthermore, the end of the inclined sliding block 11 away from its inclined surface is fixedly connected to a double-groove moving plate 12, and two sliding shaft grooves 18 are provided on the double-groove moving plate 12. The ends of the four fixed shafts 7 close to the double-groove moving plate 12 are fixedly connected to rotating shafts, and the corresponding two rotating shafts are slidably connected to the inner walls of the corresponding sliding shaft grooves 18.

[0028] Furthermore, one end of the corresponding two connecting rods 8 away from the double-groove movable plate 12 is rotatably connected to a rotating seat 9, and an arc-shaped measuring plate 10 for measuring the inner hole is fixedly connected between the corresponding two rotating seats 9.

[0029] Furthermore, a tension spring fixing plate 13 is fixedly connected to the rear end of the fixed seat 6, a tension spring 14 is fixedly connected between the double-slot movable plate 12 and the tension spring fixing plate 13, a slide groove 16 is opened on the upper surface of the fixed seat 6, and a pulling handle 15 is fixedly connected to the outer surface of the double-slot movable plate 12, and the pulling handle 15 extends out of the outer surface of the slide groove 16.

[0030] Furthermore, when in use, by placing the device at a suitable position, the shaft hole detection device is moved to a height that matches the inner hole of the shaft hole of the reducer housing, and by pulling the pulling handle 15, the pulling handle 15 drives the tension spring 14 to stretch and deform through the double-groove moving plate 12. When the double-groove moving plate 12 moves, it drives one end of the four connecting rods 8 to move together through the two sliding shaft grooves 18 until the four connecting rods 8 rotate along the axis of their respective fixed shafts 7. At this time, the two arc-shaped measuring plates 10 shrink inward at the same time until they can be inserted into the shaft hole of the reducer housing to be detected. And it continues to fit with the inner wall of the shaft hole of the reducer case, and when the double-slot movable plate 12 moves, it will also drive the inclined slider 11 thereon to move at the same time.

If the size of the inner wall of the reducer case shaft hole is unstable, the pointer display result of the micrometer 5 will also be unstable. In this way, the actual deviation value of the inner wall size of the reducer case shaft hole can be obtained, so that corresponding measures can be taken according to the deviation value, which improves the efficiency of reducer case processing to a certain extent and reduces the scrap rate of products.

[0032] Working principle: When in use, place the device in a suitable position, move the shaft hole detection device to a height that matches the inner hole of the reducer housing shaft hole, and pull the pull handle 15. The pull handle 15 drives the tension spring 14 to stretch and deform through the double-groove moving plate 12. When the double-groove moving plate 12 moves, it drives one end of the four connecting rods 8 to move together through the two sliding shaft grooves 18 until the four connecting rods 8 rotate along the axis of their respective fixed shafts 7. At this time, the two arc-shaped measuring plates 10 shrink inward at the same time until they can be inserted into the shaft hole of the reducer housing to be detected. And it continues to fit with the inner wall of the shaft hole of the reducer case, and when the double-slot movable plate 12 moves, it will also drive the inclined slider 11 thereon to move at the same time. At this time, the height position of the contact between the upper inclined surface and the detection end of the micrometer 5 can change with the size of the inner wall of the shaft hole of the reducer case, so that the size of the inner wall of the shaft hole of the reducer case can be indirectly displayed on the micrometer 5. Through the operation of the above structure, the size of the inner wall of the shaft hole of the reducer case can be quickly and conveniently detected, avoiding the time-consuming and laborious detection of the shaft hole of the reducer case in the traditional way.

[0033] Furthermore, when the rotating sleeve 4 is rotated, the two arc-shaped measuring plates 10 continuously fit with the inner wall of the reducer case shaft hole. If the size of the inner wall of the reducer case shaft hole is unstable, the pointer display result of the micrometer 5 will also be unstable. In this way, the actual deviation value of the inner wall size of the reducer case shaft hole can be obtained, so that corresponding measures can be taken according to the deviation value, which improves the efficiency of reducer case processing to a certain extent and reduces the scrap rate of products.
