In this embodiment, the bottom plate 3 is a circular plate. The left side and the right side of the bottom plate 3 are respectively provided with a plane, and the two planes are parallel to each other. The two planes are both used as fixed reference surfaces, the left plane is used for fixing the limiting frame 17, and the right plane is used for fixing the meter frame 20. A round through hole 4 is arranged on the surface of the bottom plate 3 close to the right plane. The circle center of the circular through hole 4 is positioned on the central line of the planes at the left side and the right side. And a distance is reserved between the circle center of the circular through hole 4 and the central point of the bottom plate 3.

Four legs 2 are vertically fixed to the bottom surface of the bottom plate 3. As shown in fig. 6, the lower ends of the legs 2 are screwed with the foot pads 1 through threads, respectively. The foot pad 1 can finely adjust the height of the support leg 2 to ensure that the whole equipment can be kept in a horizontal state.

As shown in fig. 1, the clamping assembly includes a middle plate 8, a connecting flange 21, and a ring gear holder 23. In this embodiment, the middle plate 8 comprises a circular disc and an annular truncated cone 34 perpendicular to the circular disc. As shown in FIG. 3, the left side of the disk is a plane which is a force bearing surface 9, and the right side of the disk is a detection end 10. A strip-shaped through hole 11 is arranged on the plate surface of the disc of the middle plate 8 close to the right detection end 10. The position of the strip-shaped through hole 11 corresponds to the position of the circular through hole 4 on the bottom plate 3. The middle plate 8 and the bottom plate 3 are connected through two pairs of same linear guide rails 14.

As shown in fig. 4 and 5, the linear guide 14 includes a rail 15 and a slider 16. Two rails 15 are fixed on the top surface of the bottom plate 3 in parallel, spaced and symmetrical mode, and two ends of the rails 15 point to the left side plane and the right side plane of the bottom plate 3 respectively. The slider 16 is fixed on the bottom surface of the middle plate 8 corresponding to the position of the track 15. The sliding block 16 is connected with the track 15 in a sliding way. An upper threaded hole 12 is formed in the center of the middle plate 8, and a lower threaded hole 5 is formed in the left side of the bottom plate 3. The lower threaded holes 5 are located on a symmetry line between the two pairs of linear guide rails 14. The upper threaded holes 12 and the lower threaded holes 5 are arranged in a staggered mode. An upper screw 13 is screwed in the upper threaded hole 12, and a lower screw 6 is screwed in the lower threaded hole 5. As shown in fig. 1, a tension spring 7 is connected between the upper screw 13 and the lower screw 6. In order to make the utility model discloses can normally detect, extension spring 7 is in the state that is stretched and has the restoring force all the time.

As shown in fig. 1, 7 to 9, a limiting frame 17 is fixed on the left side plane of the bottom plate 3, and a shift lever 18 passes through the limiting frame 17. The end of the shift lever 18 is against the force-bearing surface 9 on the left side of the middle plate 8. As shown in fig. 1, 10 and 11, a dial gauge 20 is fixed to the right plane of the base plate 3, a dial gauge 19 is fixed to the dial gauge 20, and a probe of the dial gauge 19 is always in vertical contact with the detection end 10 on the right side of the middle plate 8. As shown in fig. 1 and 12, the shaft of the shift lever 18 can be connected with the limiting frame 17 in an articulated manner, and a space for the shift lever 8 to rotate is provided at the position where the limiting frame 17 is articulated with the shift lever 18. The shift lever 18 can rotate on the stop bracket 17 around a hinge point. The shift lever 18 and the limiting frame 17 can also be connected in a sliding way. As long as it can be ensured that the shifting lever 18 can apply a force to the force-bearing surface 9 to push the middle plate 8 to move relative to the bottom plate 3. The shifting lever 18 pushes the middle plate 8 to move for a distance larger than the depth of engagement between the gear to be measured 24 and the standard gear 26.

As shown in fig. 1 and 13, the upper end of the middle plate 8 is capped with a connecting flange 21. The center of the connecting flange 21 is a round hole 22, and the flange 30 is connected with the outer circumference of the annular round platform 34 of the middle plate 8 through a bearing. The bearing is a deep groove ball bearing 33. As shown in fig. 1, 14, and 15, one ring gear fixing bracket 23 is fixed to each of the right and left sides of the connecting flange 21. The ring gear fixing frame 23 and the edge of the connecting flange 21 form a groove with an upward opening. The edge of the gear 24 to be measured is inserted into the grooves at the two sides of the connecting flange 21. In order to ensure that the gear 24 to be tested can be stably clamped in the groove, a jacking screw 25 is screwed on the gear ring fixing frame 23, and the end part of the jacking screw 25 is abutted against the outer side of the edge of the gear 24 to be tested.

The gear 24 to be tested needs to be matched with the standard gear 26. The specific connection structure of the standard gear 26 in the present invention is as follows:

as shown in fig. 1 and 16, the transmission shaft 28 sequentially passes through the circular through hole 4 of the bottom plate 3, the strip-shaped through hole 11 of the middle plate 8, the circular hole 22 of the connecting flange 21, and the gear ring to be detected. The length of the strip-shaped through hole 11 and the diameter of the round hole 22 are both larger than the shaft diameter of the transmission shaft 28. The upper end of the transmission shaft 28 is sleeved with a standard gear 26, and the standard gear 26 is fixed with the transmission shaft 28 through a pre-tightening nut 27. The master gear 26 may be in meshing relationship with the gear 24 to be tested. The lower end of the transmission shaft 28 is connected with a rotating shaft of a driving motor 32 through a coupler 31, a shell of the driving motor 32 is fixed with the bottom surface of the base through a flange 30, and the transmission shaft 28 is connected with the flange 30 through an angular contact bearing 29.

The principle of meshing the master gear 26 with the gear 24 to be measured is as follows: since the bottom plate 3 and the middle plate 8 are connected by the linear guide rail 14, the bottom plate 3 and the middle plate 8 can slide left and right along the rail 15. And because the end of the deflector rod 18 is abutted against the force bearing surface 9 on the left side of the middle plate 8, when the deflector rod 18 is pushed to enable the middle plate 8 to slide towards the right side along the linear guide rail 14, the tension spring 7 is stretched. At this time, the connection flange 21 connected to the middle plate 8 through the deep groove ball bearing 33 moves to the right side in synchronization with the middle plate 8. The gear 24 to be measured, which is clamped in the groove of the connecting flange 21 and the gear ring fixing frame 23, moves to the right side, and is separated from the standard gear 26 at the end of the transmission shaft 28. When the shift lever 18 is reset, the middle plate 8 will move to the left under the restoring force of the tension spring 7, and then the gear 24 to be tested is driven to move to the left. Since the tension spring 7 always has a restoring force, the gear to be measured 24 and the standard gear 26 can always be kept in a stable meshed state.

During detection, the standard gear 26 is meshed with the gear 24 to be detected, and the power supply of the driving motor 32 is switched on. The standard gear 26 rotates with the driving motor 32, and further drives the gear 24 to be measured engaged therewith to rotate. Since the dial indicator 19 is always vertically contacted with the detection end 10 of the middle plate, after the standard gear 26 drives the gear 24 to be detected to rotate for one circle, the difference value between the maximum indication value and the minimum indication value on the dial indicator 19 is the jitter value of the gear 24 to be detected. When the reading fluctuation of the dial indicator 19 is large, the tooth part of the gear 24 to be measured is indicated to have bruise or other abnormal conditions. And stopping the detection after the gear to be detected 24 rotates for one circle, pushing the deflector rod 18 after the detection is finished, separating the standard gear 26 from the gear to be detected 24, taking down the gear to be detected 24, and finishing the whole detection process. The operation is cycled through in the manner described above while the next part is inspected. And the rapid detection of the parts can be realized.
