The device includes a base, a mounting base, a support base, and a dial indicator. The mounting base is located on top of the base, and the support base is fixedly mounted on top of the mounting base. The dial indicator is horizontally and fixedly mounted on the support base. A crossbeam is also provided on the side wall of the support base, and a swing seat is hinged to the end of the crossbeam. A vertical mounting rod is provided on the swing seat, and a measuring ball is provided at the bottom of the mounting rod. Under the action of gravity, the mounting rod remains vertical, and the contact of the dial indicator is in close contact with the mounting rod. A support and a positioning seat are provided at the bottom of the base. The support is longer than the base, and the positioning seat is used to insert into the tooth groove of the end-face gear. This device solves the problem that existing equipment is inconvenient for detecting the symmetry of end-face gears. However, this device cannot effectively adjust the three-dimensional angle when detecting end-face gears, which limits its measurement capabilities. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a device for detecting the symmetry of an end face gear, comprising: a base 2, a fixed rod 6 fixedly connected to the upper rear end of the base 2 at the center position, a second groove 9 opened at the rear end of the fixed rod 6, a screw 10 rotatably connected to the center position inside the second groove 9, a second sliding rod 8 fixedly connected to both ends inside the second groove 9, a second slider 11 slidably connected to the second groove 9, the second slider 11 slidably connected to the second sliding rod 8, and the second slider 11 threadedly connected to the screw 10;

[0027] A motor 4 is fixedly connected to the center of the top rear side of the fixed rod 6. The coupling at the output end of the motor 4 passes through the fixed rod 6 and is fixedly connected to the screw 10.

[0028] The rear end of slider 21 is fixedly connected to a lifting platform 21. The two ends of the inner side of the lifting platform 21 are slidably connected to square rods 5. The square rods 5 can move inside the lifting platform 21, thereby driving the dial indicator 1 at the front end to move.

[0029] A dial indicator 1 is fixedly connected to the front end of the square rod 5. Holes are opened on both sides of the upper end of the lifting platform 21 and threads are provided in the holes. Bolts 7 are connected to the threads in the holes at the upper end of the lifting platform 21. Rotating the bolts 7 can make the bolts 7 and the square rod 6 come into close contact, thereby fixing the square rod 5.

[0030] The dial indicator 1 has scale needles 12 fixedly connected around its inner side. The dial indicator 1 has a rotating shaft 15 rotatably connected at the center of its inner side. There are a total of 12 scale needles 12, each with an equal angle. The scale needles 12 display different scales arranged from smallest to largest.

[0031] A pointer 13 is fixedly connected to the upper end of the rotating shaft 15, and a pin 14 is slidably connected to the lower end of the rotating shaft 15. When the pin 14 contacts the lower end, it will slide upward. With the cooperation of the internal components of the dial indicator 1, the rotating shaft 15 will rotate, thereby causing the pointer 13 on the rotating shaft 15 to rotate synchronously and point to the scale needle 12.

[0032] The upper end of the base 2 is provided with a slide groove 20, and a slide rod 3 is fixedly connected to the inner side of the slide groove 20. The position of the slide rod 3 is set in the center of the inner side of the slide groove 20, so that the slide block 19 can always slide horizontally when the slider 19 slides.

[0033] A slider 19 is slidably connected to the inner side of the slide groove 20. The slider 19 is slidably connected to the slide rod 3. A movable plate 16 is fixedly connected to the upper end of the slider 19. The sliding of the slider 19 can drive the movable plate 16 at the upper end to change its position.

[0034] A hydraulic rod 17 is fixedly connected to the inner side of the movable plate 16. A limiting plate 18 is fixedly connected to the front end of the hydraulic rod 17. When the gear is placed in the middle of the limiting plate 18, the hydraulic rod 17 at the rear end of the limiting plate 18 will move backward. After the gear is placed, the hydraulic rod 17 will push the limiting plate 18 forward, thereby making the gear tightly clamped.

[0035] Working principle: In use, the gear is placed inside the limiting plate 18 at the upper end of the movable plate 16. Since the size of the gear is larger than the distance between the limiting plates 18, the limiting plate 18 will compress the hydraulic rod 17 backward. After the gear is fully placed, the hydraulic rod 17 at the rear end of the limiting plate 18 will reset, causing the limiting plate 18 to move forward, thus firmly fixing the gear. After the gear is fixed, the drive motor 4 is driven to rotate synchronously under the rotation of the motor 4. Under the threaded connection, the second slider 11 moves along the second slide rod 8 inside the second slide groove 9, thereby driving the lifting platform 21 connected to the outside of the second slider 11 to move. The movement of the lifting platform 21 drives the inner square rod 5 and the front end The dial indicator 1 is moved. When the dial indicator 1 reaches the appropriate position, the rotation of the motor 4 is stopped. At this time, the bolt 7 is rotated to unlock the square rod 5. The position of the square rod 5 is adjusted back and forth so that the pin 14 at the lower end of the dial indicator 1 can contact the end face of the gear for end face detection. At this time, the bolt 7 is rotated in the opposite direction to lock the square rod 5, preventing the position of the square rod 5 from shifting during detection. The movable plate 16 is pulled, and the slider 19 at the lower end of the movable plate 16 slides along the slide rod 3 inside the slide groove 20, which can cause the position of the gear at the upper end of the movable plate 16 to change laterally. By setting the square rod 5, the motor 4 and the movable plate 16, the symmetry of the end face gear can be detected.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
