DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Please refer to the accompanying Figures 1-6

[0027] Detection platform 1, drive assembly 2, connecting assembly 3, detection assembly 4 and correction assembly 5, the detection platform 1 includes detachable connecting mesa 10 and base 11, the base 11 is equipped with installation cavity 12, and the bottom of the base 11 is equipped with a plurality of support legs 110 fixedly connected thereto, the drive assembly 2 includes drive motor 20, drive shaft 21, drive gear 22 and mounting plate 23, the mounting plate 23 is located at the intermediate position of a plurality of support legs 110, and it is fixedly connected with a plurality of support legs 110 respectively, the drive motor 20 is fixedly connected to the mounting plate 23, the drive gear 22 is located at the intermediate position of the installation cavity 12, one end of the drive shaft 21 is connected with the drive motor 20, the other end passes through the base 11 and is keyed connected with the drive gear 22, and the drive shaft 21 is bearing connected with the base 11, the connecting assembly 3 is movably connected with the detection platform 1, the detection assembly 4 is movably connected to the mesa 10, and the correction assembly 5 is matched with the detection platform 1.

[0028] Specifically, the mesa 10 is equipped with a plurality of symmetrically arranged mounting holes 100, and the cavity wall of the installation cavity 12 is equipped with a plurality of matching holes 120 matched with the mounting holes 100.

[0029] Specifically, the connecting assembly 3 includes connecting shaft 30, outer connecting gear 31 and inner connecting gear 32, one end of the connecting shaft 30 passes through the inner connecting gear 32 and is bearing connected in the matching hole 120, the other end passes through the mounting hole 100 and is keyed connected with the outer connecting gear 31, the connecting shaft 30 is gap connected with the mounting hole 100, is keyed connected with the inner connecting gear 32, and the inner connecting gear 32 is meshed connected with the drive gear 22.

[0030] The drive gear 22 in the drive assembly 2 is placed in the installation cavity 12 in the detection platform 1, which expands the actual available space of the mesa 10, and through the matching use of the mounting hole 100 on the mesa 10 and the matching hole 120 in the base 11, through the increase of the installation position of the connecting assembly 3, the purpose of expanding the application range is achieved, wherein through controlling the specifications of the outer connecting gear 31 and the inner connecting gear 32, the number of the connectable components of the connecting assembly 3 can be further improved, and the specific embodiments are as follows:

[0031] For the convenience of description, the outer connecting gear 31 and the inner connecting gear 32 are respectively selected as A, B and C according to different radii, wherein the radius of the A type is the smallest, and the radius of the C type is the largest. After the driving gear 22 is installed, different inner connecting gears 32 can be selected to position the position of the connecting shaft 30. For example, the inner connecting gear 32 of the A type is used, and the position of the connecting shaft 30 is closer to the driving gear 22 due to the smaller radius. The inner connecting gear 32 of the C type is used, and the position of the connecting shaft 30 is away from the driving gear 22. This setting is mainly used to distinguish the types of the gear ring. If the gear ring to be detected is an inner gear ring, the outer connecting gear 31 needs to be located on the inner side of the gear ring to complete the meshing of the outer connecting gear 31 and the inner gear ring. At this time, the A type inner connecting gear 32 can be matched with the B type outer connecting gear 31 or the B type inner connecting gear 32 can be matched with the A type outer connecting gear 31 to adapt the gear ring. If the gear ring to be detected is an outer gear ring, the outer connecting gear 31 needs to be located on the outer side of the gear ring to complete the meshing of the two. In this case, the C type inner connecting gear 32 can be matched with the B type outer connecting gear 31 or the B type connecting gear 32 can be matched with the C type outer connecting gear 31 to adapt the gear ring. Different combinations can not only complete the adaptation of the gear ring, but also control the linear speed of the gear ring according to different combinations. The above examples only set three variables, and only the outer connecting gear 31 and the inner connecting gear 32 are used as variables. In actual application, there are more than three variables according to different gear radii, and the driving gear 22 is also used as a variable. Therefore, the number of combinations is more, that is, the number of gear rings that can be adapted after combination is more. At the same time, some non-standard gear rings can also be adapted by controlling the variables, especially in the production of some small batch and multi-specification gear rings. The demand for molds is greatly reduced, the cost is reduced, the requirement for the proficiency of the operator is also reduced by simply calculating the three gears to adapt the gear ring. Even the requirement for the proficiency of the operator is further reduced by using computer memory formula calculation.

[0032] After the adaptation of the gear ring is completed, the driving motor 20 can be used as power to drive the rotation of the gear ring, and the use of the detection assembly 4 or the correction assembly 5 can be selected according to product requirements.

[0033] Specifically, the connecting assembly 3 is provided with at least two groups, and the two groups of connecting assemblies 3 are located at the symmetrical positions of the driving gear 22.

[0034] In actual application, if only a single connecting assembly 3 is used, the position of the gear ring will be offset. In this case, at least two groups of connecting assemblies 3 with relatively symmetrical positions are needed to ensure that the position of the gear ring does not deviate.

[0035] Specifically, the detection assembly 4 comprises a sliding plate 40, an L-shaped plate 41, a sliding block 42, a locking nail 43, a micrometer 44, an adjusting bolt 45 and a plurality of positioning bolts 46. The sliding plate 40 is provided with a sliding groove 400, the bottom wall of the sliding groove 400 is provided with a plurality of through holes 4001, the positioning bolts 46 pass through the through holes 4001 and are located in the mounting holes 100, and the positioning bolts 46 are in threaded connection with the through holes 4001. The sliding block 42 is slidingly connected in the sliding groove 400. The adjusting bolt 45 passes through the transverse plate of the L-shaped plate 41 and is in threaded connection with the sliding block 42, and the adjusting bolt 45 is in clearance fit with the L-shaped plate 41. The longitudinal plate of the L-shaped plate 41 is provided with a penetrating hole 411. The locking nail 43 passes through the top wall of the longitudinal plate of the L-shaped plate 41 and is in contact with the micrometer 44 located in the penetrating hole 411, and the locking nail 43 is in threaded connection with the L-shaped plate 41.

[0036] Considering the problem of deformation of part of the gear ring, if the gear ring is detected by naked eyes, firstly, the deformation cannot be directly observed, and secondly, workers are easy to judge some gear rings with slight deformation as qualified in long-time observation. Therefore, the detection assembly 4 is arranged. Firstly, according to the position of the gear ring, the position of the sliding plate 40 can be locked by the positioning bolts 46. One end of the positioning bolt 46 is in threaded connection with the through hole 4001 of the sliding groove 400, and the other end is inserted into the mounting hole 100 arranged on the table top 10. Considering the problem that the hole diameters of the through hole 4001 and the mounting hole 100 can be different, the positioning bolt 46 can be provided with different diameters at two ends. As shown in the accompanying drawings, if the hole diameters of the through hole 4001 and the mounting hole 100 are the same, the positioning bolt 46 can also be provided with a rod structure. Figure 4

[0037] After the position of the sliding plate 40 is determined and installed, the subsequent installation can be divided into two modes. Firstly, the vertical position of the sliding block 42 is changed by the adjusting bolt 45, so that the sliding block 42 has a gap with the top wall of the sliding groove 400. In this case, the positions of the sliding block 42 and the L-shaped plate 41 are moved to be close to the gear ring. Then, the locking nail 43 is used to unlock the micrometer 44. After the micrometer 44 is adjusted to a suitable position, the micrometer 44 is locked. The second adjusting mode is that the position of the micrometer 44 is locked in advance by the locking nail 43. Then, the position of the sliding block 42 is adjusted to control the contact between the micrometer 44 and the gear ring. The two modes have advantages and disadvantages, and the operator can adjust according to his own habits.

[0038] ​Specifically, the correction assembly 5 comprises a correction disc 50, a double-output shaft stepper motor 55, two groups of inner threaded cylinders 56, two groups of screw rods 57 and a clamping plate 58, a plurality of uniformly distributed strip-shaped grooves 500 are arranged on the correction disc 50, the double-output shaft stepper motor 55 is fixedly connected to the middle position of the correction disc 50, the two groups of inner threaded cylinders 56 are respectively fixedly connected with two rotating shafts of the double-output shaft stepper motor 55, the upper end of the clamping plate 58 is slidably connected in the strip-shaped groove 500, one end of the two groups of screw rods 57 is respectively fixedly connected with the two groups of clamping plates 58, the other end is respectively threadedly connected with the two groups of inner threaded cylinders 56, and the screw directions of the two groups of inner threaded cylinders 56 are opposite.

[0039] When the gear ring needs to be corrected due to serious deformation during detection, first, the L-shaped plate 41 is removed (in actual application, if the height of the correction disc is greater than the height of the longitudinal plate of the L-shaped plate 41, that is, the L-shaped plate 41 and the micrometer 44 do not affect the work of the correction assembly 5, the L-shaped plate 41 can be selected not to be removed), then the double-output shaft stepper motor 55 is started to drive the inner threaded cylinder 56 fixedly connected therewith to rotate, due to the opposite screw directions of the two groups of inner threaded cylinders 56, under the condition that the rotating shaft directions of the two ends of the rotating shaft of the double-output shaft stepper motor 55 are the same, the screw rod will move the clamping plate 58 towards the direction close to or away from the double-output shaft stepper motor 55, and the gear ring side wall is contacted and extruded by the synchronous movement of the clamping plate 58, so as to achieve the purpose of clamping correction.

[0040] It should be noted that the single correction assembly 5 is used in the utility model, but it does not mean that the structure can only use one correction assembly 5, if multiple correction assemblies 5 are needed, a matching motor frame can be built, different height clamping plates 58 are used, the cross method is used in the longitudinal direction, and the switches of multiple double-output shaft stepper motors 55 are uniformly controlled (the multiple correction assembly 5 staggered structure diagram is shown in FIG. 8). Figure 6 。

[0041] Example two

[0042] Please refer to the accompanying Figures 7-8

[0043] Specifically, the correction assembly 5 comprises a correction disc 50, a cylindrical shell 51, a winding column 52, an adjusting handle 53 and a plurality of tightening assembly 54, the correction disc 50 is provided with a plurality of uniformly distributed strip-shaped grooves 500, the tightening assembly 54 is respectively slidably connected in the strip-shaped grooves 500, the cylindrical shell 51 is fixedly connected at the middle position of the correction disc 50 and is provided with a plurality of threading holes 501 matched with the tightening assembly 54, the winding column 52 is located in the cylindrical shell 51, the rotating shaft of the motor 53 is fixedly connected with the winding column 52 through the top wall of the cylindrical shell 51, and the rotating shaft of the motor 53 is bearing-connected with the cylindrical shell 51.

[0044] Specifically, the tightening assembly 54 comprises a guide wheel 540, a tightening plate 58 and two groups of pull wires 542, the guide wheel 540 is located at one end of the strip-shaped groove 500 away from the cylindrical shell 51 and is fixedly connected with the correction disc 50, the upper end of the tightening plate 58 is slidably connected in the strip-shaped groove 500, one end of one group of the pull wires 542 is fixedly connected with the side wall of the tightening plate 58 close to the cylindrical shell 51, and the other end is wound on the winding column 52 through the threading hole 501 matched with the position, one end of the other group of the pull wires 542 is fixedly connected with the side wall of the tightening plate 58 away from the cylindrical shell 51, and the other end is wound on the winding column 52 after passing through the guide wheel 540 and the threading hole 501 matched with the position;

[0045] When the gear ring is severely deformed during detection, the roundness of the gear ring needs to be corrected. First, the L-shaped plate 41 and the micrometer 44 are disassembled (in actual application, if the height of the correction disc is greater than the height of the longitudinal plate of the L-shaped plate 41, i.e., the L-shaped plate 41 and the micrometer 44 do not affect the work of the correction assembly 5, the L-shaped plate 41 can be selected not to be disassembled), then the correction assembly 5 is adjusted according to the type of the gear ring, the rotation of the winding column 52 is driven by the motor 53, and with the rotation of the winding column 52, the plurality of tightening assemblies 54 are moved. If the gear ring is an inner gear ring, it means that the outer side of the gear ring needs to be tightened. At this time, the position of the tightening plate 58 is adjusted so that the distance from the tightening plate 58 to the center of the winding column 52 is greater than the radius of the inner gear ring. Then the correction disc 50 is covered on the inner gear ring, and the tightening plate 58 is located outside the inner gear ring. Then the motor 53 is started again to drive the tightening plate 58 to continue moving towards the inner gear ring, until it abuts against the outer side wall of the inner gear ring from different positions. After a long time of static tightening, the roundness correction of the gear ring is completed.

[0046] If the gear ring to be corrected is an outer gear ring, the distance between the clamping plates 58 and the winding column 52 needs to be smaller than the radius of the outer gear ring during the preliminary adjustment, so that when the correction disc 50 is placed on the outer gear ring, all the clamping plates 58 are located inside the outer gear ring.

[0047] During the whole correction process, the movement speed of the multiple clamping plates 58 is synchronized, so that even if the correction disc 50 and the gear ring are misaligned at the initial position, the automatic adjustment can be achieved, and the roundness of the corrected gear ring can be ensured.

[0048] It should be noted that, in order to avoid the problem that the correction required force is too large due to the excessive friction force between the clamping plates 58 and the table 10 during the correction process, the side wall of the clamping plate 58 in contact with the table 10 can be provided with a ball to reduce the friction force. Since the above-mentioned technologies are relatively mature, the present application will not be described in detail.

[0049] Specifically, the winding directions of the two groups of pulling lines 542 on the winding column 52 are opposite, and the strip-shaped groove 500 is provided with a scale;

[0050] The winding directions of the two groups of pulling lines 542 on the same clamping plate 58 are opposite, so as to associate the forward and reverse rotation of the winding column 52 with the displacement direction of the clamping plate 58, and the scale provided on the strip-shaped groove 500 is also beneficial to the judgment of the position of the clamping plate 58 by the staff. Considering that the correction disc 50 may have the problem of excessive weight due to the solid structure, the correction disc 50 can adopt a structure with a large number of hollows in actual application.

[0051] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent substitutions or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
