Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing, in particular to a gear ring rounding and leveling detection tool. Background Art

[0002] The roundness of the inner hole of the gear ring and the surface parallelism of the gear ring are very important parameters for the finished gear ring, which directly affect the quality of the gear ring product. At present, there are many ways to detect the inner hole of the gear ring. One is the traditional manual measurement, in which workers directly use a dial indicator to measure. This method is inaccurate, difficult to operate, and very inefficient. The other is to place the gear ring horizontally on the inspection platform, and then place the two ends of the dial indicator against the inner hole wall, and then rotate the dial indicator along the inner hole wall to check the data changes, and then detect the roundness of the inner hole of the gear ring. In this operation method, since the dial indicator is manually rotated and the position of the gear ring is not fixed, the worker has to rotate the dial indicator during measurement. , resulting in a relatively slow operation process and low efficiency; another is the utility model patent with announcement number CN201331326Y, which discloses a gear inner hole roundness detection device, including an inclined flat plate on a support frame, which is tilted backward; a dial indicator is set on the flat plate below the bearing. During detection, the gear to be tested is placed on a pile of bearings, and the bottom surface of the gear contacts the inclined flat plate. Due to the inclined setting of the flat plate, the inner hole of the gear mounted on a pair of bearings contacts the outer side surfaces of the two bearings under the action of gravity. The dial indicator is fixed, the probe corresponds to the inner hole of the gear, and the gear is rotated to easily measure the inner hole roundness parameters of the gear. However, the above method only detects the inner hole roundness of the gear and cannot measure the parallelism of the ring gear surface.

[0035] Example:

[0036] Reference Figures 1-8 As shown, a gear ring rounding and leveling detection tool comprises a support base, on which a gear ring positioning mechanism 3, a rounding mechanism 4 and a leveling mechanism 5 are provided;

[0037] The gear ring positioning mechanism 3 includes two sets of rotating mechanisms. The rotating mechanism includes a positioning shaft 301. One end of the positioning shaft 301 is rotatably provided with a roller 302. The other end passes through the support seat and is fixed by a locking nut. The inner hole of the gear ring to be tested abuts against the roller 302.

[0038] The roundness calibration mechanism 4 includes a first dial indicator 403 and a positioning assembly. The first dial indicator 403 is arranged on a support seat through the positioning assembly.

[0039] The leveling mechanism 5 includes a second dial indicator 503 and a rotating bracket 502 . One end of the rotating bracket 502 is arranged on the support seat, and the other end is provided with the second dial indicator 503 .

[0040] Roller 302 is mounted on a support base via positioning shaft 301. The ring gear is placed on the support base. The inner wall of the ring gear rests against roller 302 of the two rotating mechanisms. Roller 302 not only supports the ring gear but also facilitates its rotation. The probe of the first dial indicator 403 rests against the inner wall of the ring gear, while the probe of the second dial indicator 503 rotates via a rotating bracket 502 and rests against the surface of the ring gear.

[0041] As the gear ring rotates, the inner hole wall of the gear ring moves on the probe of the first dial indicator 403. Since the position of the first dial indicator 403 remains unchanged, the change in the inner hole wall of the gear ring will directly act on the first dial indicator 403, and the change in the measurement data of the first dial indicator 403 can reflect the roundness of the inner hole of the gear ring; similarly, as the gear ring rotates, the surface of the gear ring will move on the probe of the second dial indicator 503. Since the position of the second dial indicator 503 remains unchanged, the change in the parallelism of the surface of the gear ring will directly act on the second dial indicator 503, and the change in the measurement data of the second dial indicator 503 can reflect the change in the parallelism of the surface of the gear ring, which improves the detection efficiency, reduces the difficulty of operation, and improves the detection accuracy, thereby maintaining the quality of the gear ring product.

[0042] The positioning assembly includes a long shaft 402 and a threaded sleeve 401. The end surface of the threaded sleeve 401 is provided with a through hole 40101 along its length for the long shaft 402 to pass through. The diameter of one end of the threaded sleeve 401 is larger than the diameter of the other end. The outer wall of the threaded sleeve 401 is provided with a first limit clamping platform 40102. The side wall of the end with a smaller diameter of the threaded sleeve 401 is provided with an external thread. The end with a smaller diameter of the threaded sleeve 401 passes through the support seat and is fixed by a nut.

[0043] A second limiting fixture 40202 is provided on the outer side wall of the long shaft 402. The diameter of one end of the long shaft 402 is larger than that of the other end. A positioning hole 40201 for fixing the first dial indicator 403 is formed on the end with the larger diameter. The diameter of the other end matches the diameter of the through hole 40101 of the threaded sleeve 401, and this end is provided with an external thread.

[0044] One end of the long shaft 402 is provided with a positioning hole 40201 for fixing the first dial indicator 403, and the other end is provided with an external thread. The diameter of the long shaft 402 matches the diameter of the through hole 40101 of the threaded sleeve 401, and the long shaft 402 has one end with the positioning hole 40201, and the end of the long shaft 402 with a smaller diameter passes through the through hole 40101 of the threaded sleeve 401 and is fixed by a nut.

[0045] After the threaded sleeve 401 passes through the support seat, it is locked by a nut, and cooperates with the first limit clamp 40102 of the side wall to make the threaded sleeve 401 clamped and fixed on the support seat, and the long shaft 402 passes through the through hole 40101 of the threaded sleeve 401 and is locked by a nut, and cooperates with the second limit clamp 40202 to fix the long shaft 402 in the threaded sleeve 401, and the first dial indicator 403 is fixed in the end positioning hole 40201 of the long shaft 402. At this time, the first dial indicator 403 is parallel to the support seat, and the probe of the first dial indicator 403 is placed against the inner hole wall of the gear ring. The inner hole wall of the gear ring squeezes the probe of the first dial indicator 403, so that the first dial indicator 403 is displayed through data, and different extrusions display different data, thereby reflecting the roundness of the inner hole of the gear ring.

[0046] The support base includes a support frame 1 and a detection plate 2. The detection plate 2 is tilted on the support frame 1. The detection plate 2 is provided with a first strip hole 201 and a second strip hole 202. The first strip hole 201 is arranged horizontally, and the positioning shaft 301 of the gear ring positioning mechanism 3 passes through the first strip hole 201.

[0047] The second strip-shaped hole 202 is located below the first strip-shaped hole 201 , and there are a plurality of second strip-shaped holes 202 distributed in a fan shape. The threaded sleeve 401 of the positioning assembly passes through the second strip-shaped holes 202 .

[0048] The positioning shaft 301 is arranged in the first strip hole 201, and the first strip hole 201 is arranged horizontally to ensure that the two sets of gear ring positioning mechanisms 3 can position and support the gear ring, while ensuring the stability of the gear ring during rotation. In addition, due to the use of strip holes, the positions of the two sets of gear ring positioning mechanisms 3 in the first strip hole 201 can be adjusted, thereby meeting the detection requirements of different models of gear rings.

[0049] The threaded sleeve 401 is located in the second strip hole 202. By adjusting the position of the threaded sleeve 401 in the second strip hole 202, the position of the long axis 402 can be adjusted, and then the position of the first dial indicator 403 can be adjusted, so as to implement gear rings with different apertures, ensure that the first dial indicator 403 is inside the gear ring, and then ensure that the probe of the first dial indicator 403 can be against the inner hole wall of the gear ring to meet the detection requirements.

[0050] By setting a plurality of second strip holes 202, a plurality of detection positions can be set in the gear ring. By performing simultaneous detection at the plurality of detection positions, the detection accuracy can be further improved, and at the same time, damage to the first dial indicator 403 can be avoided, which would affect the detection accuracy.

[0051] The diameter of the smaller end of the positioning shaft 301 matches the width of the first strip-shaped hole 201 , and a first milling plane 30101 is provided on the middle sidewall of the positioning shaft 301 .

[0052] The first milling plane 30101 prevents the positioning shaft 301 from rotating in the first strip hole 201, thereby ensuring that the position of the roller 302 is fixed, thereby ensuring that the roller 302 supports the ring gear and preventing the gear support from being unstable and affecting the accuracy of gear detection.

[0053] The diameter of the smaller end of the threaded sleeve 401 matches the width of the second strip-shaped hole 202 , and a second milling plane 40103 is provided on the middle side wall of the threaded sleeve 401 .

[0054] The second milling plane 40103 prevents the threaded sleeve 401 from rotating in the second strip hole 202, thereby ensuring the position of the threaded sleeve 401 in the second strip hole 202, thereby ensuring the position of the first dial indicator 403, and ensuring that the first dial indicator 403 is in contact with the inner hole wall of the gear ring, thereby ensuring the detection accuracy.

[0055] The rotating bracket 502 includes a first connecting rod 50201 and a second connecting rod 50202. The first connecting rod 50201 is arranged on the detection plate 2, and the other end is hinged to one end of the second connecting rod 50202. The other end of the second connecting rod 50202 is provided with a clamping hole, and a second dial indicator 503 is arranged in the clamping hole.

[0056] By rotating the bracket 502, the second dial indicator 503 can be easily contacted with the surface of the ring gear. When placing the ring gear, the second dial indicator 503 needs to be lifted up. Therefore, the second dial indicator 503 can be easily moved by hinged connection between the second connecting rod 50202 and the first connecting rod 50201.

[0057] It also includes a meter base 501 , which is fixed on the detection plate 2 , and the end of the first connecting rod 50201 is rotatably set on the meter base 501 .

[0058] The first connecting rod 50201 can be conveniently set on the detection platform through the dial base 501, and the rotatable setting of the first connecting rod 50201 further improves the convenience of moving the second dial indicator 503.

[0059] When in use, first adjust the distance between the two sets of gear ring positioning mechanisms 3 in the first strip hole 201 according to the model of the gear ring. After the adjustment is completed, lock the positioning shaft 301 by the nut to fix the two sets of gear ring positioning mechanisms 3. Then, rotate the second dial indicator 503 by rotating the bracket 502. Then, put the gear ring on the roller 302 of the gear ring positioning mechanism 3 so that the inner hole wall of the gear abuts against the roller 302. Then, pass the long shaft 402 through the threaded sleeve 401 and lock the position of the long shaft 402 by the nut. Then clamp the threaded sleeve 401 in the second strip hole 202 so that the probe of the first dial indicator 403 on the long shaft 402 abuts. On the inner hole wall of the gear ring, the threaded sleeve 401 is fixed in the position of the second strip hole 202 by a nut, thereby fixing the position of the first dial indicator 403. By rotating the rotating bracket 502, the probe of the second dial indicator 503 is made to rest against the surface of the gear ring. The worker manually rotates the gear ring, and the gear ring rolls on the roller 302. At the same time, the inner hole wall of the gear ring moves on the probe of the first dial indicator 403, and the surface of the gear ring moves like the probe of the second dial indicator 503. The data changes of the first dial indicator 403 reflect the roundness of the inner hole of the gear ring, and the data changes of the second dial indicator 503 reflect the parallelism of the gear ring surface, thereby completing the inspection of the gear ring.

[0060] In actual use, a plurality of second strip holes 202 are provided on the detection plate 2, corresponding positioning components are provided in the second strip holes 202, and corresponding first dial indicators 403 are provided at the same time. By performing simultaneous detection with the plurality of first dial indicators 403, the detection accuracy is further improved.

[0061] The utility model has a simple structure and is easy to use, greatly improves work efficiency and detection accuracy, and is suitable for promotion.

[0062] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them.
