Technical Field

[0001] The present invention relates to the technical field of gear rings, and in particular to a gear ring detection and correction device. Background Art

[0002] The gear ring is a spare part that is inserted on the outer edge of the flywheel after heating and fastened to the outer edge of the flywheel after cooling. It is used to mesh with the starter gear. The existing gear ring will have the following problems after processing. First, after the heat treatment, some parts of the gear ring are deformed, and the gear ring needs to be corrected in time. In the existing processing method, the gear ring needs to be inspected first, and the problems are collected and sent to the correction area for correction. The process is cumbersome, time-consuming and labor-intensive. Second, there are many specifications of gear rings, and gear rings of different specifications need to be corrected with different molds. At the same time, the gear ring is divided into two types: inner gear ring and outer gear ring according to the position of the teeth. The detection and correction molds of the inner gear ring and the outer gear ring are also different. Therefore, a large number of molds for detection are required in the production of the gear ring, which indirectly increases the manufacturing cost. In addition, in the detection of gear rings of multiple specifications and small batches, certain requirements are also placed on the proficiency of the staff. In view of this, there is an urgent need for a gear ring detection and correction device that can solve the above problems. Summary of the invention

[0006] Preferably, the connecting assembly includes a connecting shaft, an external connecting gear and an internal connecting gear.

The connecting shaft is gap-connected to the mounting hole and is key-connected to the internal connecting gear, and the internal connecting gear is meshedly connected to the driving gear.

[0007] Preferably, there are at least two groups of connecting components, and the two groups of connecting components are respectively located at symmetrical positions of the driving gear.

[0008] Preferably, the detection assembly includes a slide plate, an L-shaped plate, a slider, a locking pin, a micrometer, an adjusting bolt and a plurality of positioning bolts. The slide plate is provided with a slide groove, and a plurality of through holes are provided on the bottom wall of the slide groove. The positioning bolt passes through the through hole and is located in the mounting hole, and the positioning bolt is threadedly connected to the through hole. The slider is slidably connected in the slide groove, and the adjusting bolt passes through the transverse plate of the L-shaped plate and is threadedly connected to the slider, and the adjusting bolt and the L-shaped plate are clearance-matched. A through hole is provided on the longitudinal plate of the L-shaped plate, and the locking pin passes through the top wall of the longitudinal plate of the L-shaped plate and contacts with the micrometer located in the through hole, and the locking pin is threadedly connected to the L-shaped plate.

[0009] Preferably, the correction assembly includes a correction disk, a double-output shaft stepper motor, two groups of internal threaded barrels, two groups of screw rods, a clamping plate and two groups of contact rods.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The driving component is built into the test bench, and the driving gear drives the ring gear to rotate indirectly through multiple sets of connecting components and the connection with the driving gear. In this mode, not only the position of the connecting component is easy to adjust, but also the connecting component has a variety of adjustment methods.

[0011] 2. The detection component is connected to the detection table by a slide plate, which makes the position of the detection component flexible and changeable. According to the different specifications of the gear ring to be detected and the different detection types, the position of the detection component can be quickly adjusted. At the same time, in order to avoid the relatively fixed position of the micrometer affecting the actual detection effect, the sliding connection between the L-shaped plate and the slide plate is adopted to make the position of the micrometer also have a certain degree of adjustment ability, which further expands the application scope of the detection component while ensuring the accuracy of the detection component.

[0012] 3. When there is a problem with the roundness of the gear ring during the detection process, the gear ring can be corrected through the correction component, and the position of the clamping plate can be adjusted to clamp the gear ring from the outside to the inside or to open the clamp from the inside to the outside.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Please see attached Figure 1-6 A detection platform 1, a driving component 2, a connecting component 3, a detection component 4 and a correction component 5, wherein the detection platform 1 comprises a table top 10 and a base 11 which are detachably connected, the base 11 is provided with a mounting cavity 12, and the bottom of the base 11 is provided with a plurality of supporting legs 110 fixedly connected thereto, the driving component 2 comprises a driving motor 20, a driving shaft 21, a driving gear 22 and a mounting plate 23, the mounting plate 23 is located in the middle of the plurality of supporting legs 110, and is respectively fixedly connected to the plurality of supporting legs 110, the driving motor 20 is fixedly connected to the mounting plate 23, the driving gear 22 is located in the middle of the mounting cavity 12, one end of the driving shaft 21 is connected to the driving motor 20, and the other end passes through the base 11 and is key-connected to the driving gear 22, and the driving shaft 21 is bearing-connected to the base 11, the connecting component 3 is movably connected to the detection platform 1, the detection component 4 is movably connected to the table top 10, and the correction component 5 matches the detection platform 1.

[0017] Specifically, the table top 10 is provided with a plurality of symmetrically arranged mounting holes 100 , and the cavity wall of the mounting cavity 12 is provided with a plurality of matching holes 120 matching with the mounting holes 100 .

[0018] Specifically, the connecting assembly 3 includes a connecting shaft 30, an outer connecting gear 31 and an inner connecting gear 32. One end of the connecting shaft 30 passes through the inner connecting gear 32 and is connected to the matching hole 120 by a bearing, and the other end passes through the mounting hole 100 and is key-connected to the outer connecting gear 31. The connecting shaft 30 is gap-connected to the mounting hole 100 and is key-connected to the inner connecting gear 32. The inner connecting gear 32 is meshedly connected to the driving gear 22. The driving gear 22 in the driving assembly 2 is placed in the mounting cavity 12 in the detection table 1. This arrangement expands the actual available space of the table 10. The mounting hole 100 provided on the table 10 and the matching hole 120 in the base 11 are used together, and the installation position of the connecting assembly 3 is increased to achieve the purpose of expanding the application range. The specifications of the external connecting gear 31 and the internal connecting gear 32 can be controlled to further increase the number of matching connecting assemblies 3, as follows: For the convenience of description, the outer connecting gear 31 and the inner connecting gear 32 are selected from three types of ABC according to different radii, among which type A has the smallest radius and type C has the largest radius. After the driving gear 22 is installed, by selecting different inner connecting gears 32, the position of the connecting shaft 30 can be positioned. For example, if a type A inner connecting gear 32 is used, due to its smaller radius, the position of the connecting shaft 30 will be closer to the driving gear 22, while if a type C inner connecting gear 32 is used, the position of the connecting shaft 30 will be far away from the driving gear 22. This setting is mainly used to distinguish the types of gear rings. If the gear ring to be detected is an internal gear ring, the outer connecting gear 31 needs to be located on the inner side of the gear ring to be detected to complete the meshing of the outer connecting gear 31 with the inner gear ring. At this time, the gear ring can be adapted by using a type A inner connecting gear 32 with a type B outer connecting gear 31 or a type B inner connecting gear 32 with a type A outer connecting gear 31. If the gear ring to be detected is an external gear ring, the outer connecting gear 31 needs to be located on the outer side of the gear ring to be detected to complete the meshing of the two. In this case, the gear ring can be adapted by matching the C-type internal connecting gear 32 with the B-type external connecting gear 31 or the B-type connecting gear 32 with the C-type external connecting gear 31. Different combinations can not only complete the adaptation of the gear ring, but also control the linear speed of the gear ring according to specific circumstances. In the above example, only three variables are set, and only the external connecting gear 31 and the internal connecting gear 32 are used as variables. In actual applications, according to the different gear radii, there are far more than three variables, and the driving gear 22 is also used as a variable, so there are more matching methods, that is, more gear rings can be adapted after matching. At the same time, some non-standard gear rings can also be adapted by controlling variables, especially in the production of some small batches of multi-specification gear rings, which greatly reduces the demand for molds and reduces costs. The gear ring is adapted by performing simple calculations on the three gears, which also indirectly reduces the requirements for the proficiency of the operator, and can even be calculated by computer memory formulas to further reduce the requirements for the proficiency of the operator. After the gear ring is adapted, the driving motor 20 can be used as a power to drive the gear ring to rotate, and the use of the detection component 4 or the correction component 5 can be selected according to product requirements.

[0019] Specifically, the connection components 3 are provided with at least two groups, and the two groups of the connection components 3 are respectively located at symmetrical positions of the driving gear 22; Considering that in actual applications, if only a single connecting assembly 3 is used, the gear ring may be offset. In this case, at least two sets of connecting assemblies 3 with symmetrical positions are required to ensure that the position of the gear ring is not offset.

[0020] Specifically, the detection assembly 4 includes a slide plate 40, an L-shaped plate 41, a slider 42, a locking pin 43, a micrometer 44, an adjusting bolt 45 and a plurality of positioning bolts 46. The slide plate 40 is provided with a slide groove 400, and the bottom wall of the slide groove 400 is provided with a plurality of through holes 4001. The positioning bolt 46 passes through the through holes 4001 and is located in the mounting hole 100, and the positioning bolt 46 is threadedly connected with the through holes 4001. The slider 42 is slidably connected in the slide groove 400, and the adjusting bolt 45 passes through the transverse plate of the L-shaped plate 41 and is threadedly connected with the slider 42, and the adjusting bolt 45 is clearance-matched with the L-shaped plate 41. The longitudinal plate of the L-shaped plate 41 is provided with a through hole 411, and the locking pin 43 passes through the top wall of the longitudinal plate of the L-shaped plate 41 and contacts with the micrometer 44 located in the through hole 411, and the locking pin 43 is threadedly connected with the L-shaped plate 41. Taking into account the problem that some gear rings are deformed, if the gear rings are inspected with the naked eye, firstly, the deformation cannot be directly observed, and secondly, workers may easily judge some gear rings with less serious deformation as qualified during long-term observation. Therefore, a detection component 4 is set. First, according to the position of the gear ring, the position of the slide plate 40 can be locked by the positioning bolt 46. One end of the positioning bolt 46 is threadedly connected to the through hole 4001 of the slide groove 400, and the other end is inserted into the mounting hole 100 provided on the table 10. Taking into account the possible problem of different apertures of the through hole 4001 and the mounting hole 100, the positioning bolt 46 can be set with different diameters at both ends, as shown in the attached figure. Figure 4 As shown in , if the through hole 4001 has the same diameter as the mounting hole 100, the positioning bolt 46 may also adopt a rod-shaped structure; After the position of the slide plate 40 is determined and installed, the subsequent installation can be divided into two methods. One is to first change the vertical position of the slider 42 by adjusting the bolt 45 so that there is a gap between the slider 42 and the top wall of the slide groove 400. In this case, the position of the slider 42 and the L-shaped plate 41 is moved to make them close to the ring gear, and then the locking pin 43 is used to release the lock of the micrometer 44, and the micrometer 44 is adjusted to a suitable position and then locked. The second adjustment method is to lock the position of the micrometer 44 in advance by the locking pin 43, and then control the contact between the micrometer 44 and the ring gear by adjusting the position of the slider 42. The two methods have their own advantages and disadvantages, and the operator can adjust according to his own habits.

[0021] Specifically, the correction component 5 includes a correction disk 50, a double-output shaft stepper motor 55, two groups of internal threaded barrels 56, two groups of screw rods 57 and a clamping plate 58. The correction disk 50 is provided with a plurality of evenly distributed strip grooves 500. The double-output shaft stepper motor 55 is fixedly connected to the middle position of the correction disk 50. The two groups of internal threaded barrels 56 are respectively fixedly connected to the two rotating shafts of the double-output shaft stepper motor 55. The upper end of the clamping plate 58 is slidably connected to the strip groove 500. One end of the two groups of screw rods 57 is respectively fixedly connected to the two groups of clamping plates 58, and the other end is respectively threadedly connected to the two groups of internal threaded barrels 56, and the spiral directions of the threads of the two groups of internal threaded barrels 56 are opposite. When the gear ring is severely deformed and needs to be corrected during the inspection process, the L-shaped plate 41 is first removed (in actual application, if the height of the correction disk is greater than the longitudinal plate height of the L-shaped plate 41, that is, the L-shaped plate 41 and the micrometer 44 do not affect the operation of the correction component 5, the L-shaped plate 41 can be selected not to be removed), and then the double-output shaft stepper motor 55 is started to drive the internal threaded barrel 56 fixedly connected to it to rotate. Since the internal threads of the two groups of internal threaded barrels 56 have opposite spiral directions, when the two ends of the shaft of the double-output shaft stepper motor 55 have the same direction, the screw will carry the clamping plate 58 to move simultaneously in the direction close to the double-output shaft stepper motor 55 or in the direction away from the double-output shaft stepper motor 55, and the side walls of the gear ring are contacted and squeezed by the synchronous movement of the clamping plate 58, thereby achieving the purpose of clamping correction.

[0022] It should be noted that the present invention adopts a single set of correction components 5, but this does not mean that the structure can only use one set of correction components 5. If multiple sets of correction components 5 are needed, matching motor racks can be built, and clamping plates 58 of different heights can be used. In a cross-shaped manner in the longitudinal direction, the switches of multiple dual-output shaft stepper motors 55 can be uniformly controlled at the same time (a schematic diagram of the misaligned structure of multiple sets of correction components 5 is shown in the attached figure). Figure 6 ). Embodiment 2

[0023] Please refer to the attached Figure 7-8 Specifically, the correction component 5 includes a correction disk 50, a cylindrical shell 51, a winding column 52, an adjusting handle 53 and a plurality of tightening hoop components 54. The correction disk 50 is provided with a plurality of evenly distributed strip grooves 500, and the tightening hoop components 54 are respectively slidably connected in the plurality of strip grooves 500. The cylindrical shell 51 is fixedly connected to the middle position of the correction disk 50, and is provided with a plurality of threading holes 501 matching the tightening hoop components 54. The tightening column 52 is located in the cylindrical shell 51, and the rotating shaft of the motor 53 passes through the top wall of the cylindrical shell 51 and is fixedly connected to the winding column 52, and the rotating shaft of the motor 53 is connected to the bearing of the cylindrical shell 51.

[0024] Specifically, the tightening hoop assembly 54 includes a guide wheel 540, a tightening hoop plate 58 and two groups of pulling wires 542. The guide wheel 540 is located at the end of the strip groove 500 away from the cylindrical shell 51, and is fixedly connected to the correction disk 50. The upper end of the tightening hoop plate 58 is slidably connected to the strip groove 500. One end of one group of pulling wires 542 is fixedly connected to the side wall of the tightening hoop plate 58 close to the cylindrical shell 51, and the other end passes through the threading hole 501 matching its position and is wound around the winding column 52. Another group of pulling wires 542 has one end fixedly connected to the side wall of the tightening hoop plate 58 away from the cylindrical shell 51, and the other end passes through the threading hole 501 matching its position and is wound around the winding column 52. When the gear ring is seriously deformed during the inspection process, it is necessary to correct the roundness of the gear ring. First, the L-shaped plate 41 and the micrometer 44 are removed (in actual application, if the height of the correction plate is greater than the longitudinal plate height 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 component 5, the L-shaped plate 41 can be selected). Then, the correction component 5 is adjusted according to the type of the gear ring, and the winding column 52 is driven to rotate by the motor 53. As the winding column 52 rotates, multiple tightening assemblies are driven. The part 54 moves. 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 disk 50 is covered on the inner gear ring to ensure that 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 to move in the direction close to the inner gear ring until it contacts the outer wall of the inner gear ring from different positions. After a long period of static tightening, the roundness correction of the gear ring is completed. If the gear ring to be corrected is an outer gear ring, the distance from the clamping plate 58 to the winding column 52 needs to be smaller than the radius of the outer gear ring during the initial adjustment to ensure that when the correction disk 50 is covered on the outer gear ring, all the clamping plates 58 are located inside the outer gear ring. The other steps are the same as the inner gear ring correction process, so they will not be repeated. During the whole calibration process, since the movement speeds of the multiple clamping plates 58 are synchronized, even if the calibration plate 50 is misaligned with the initial position of the gear ring, the purpose of automatic adjustment can be achieved, thereby ensuring the roundness of the gear ring after calibration; It should be noted that in order to avoid the problem of excessive force required for correction due to excessive friction between the tightening plate 58 and the table 10 during the correction process, a ball bearing can be set on the side wall of the tightening plate 58 on the side in contact with the table 10 to reduce friction. In view of the fact that the above technologies are relatively mature technologies, they will not be repeated in the present invention.

[0025] Specifically, the winding directions of the two groups of pulling wires 542 on the winding rod 52 are opposite, and the strip groove 500 is provided with scales; The two sets of pulling wires 542 on the same tightening plate 58 are wound in opposite directions so that the forward and reverse rotation of the winding column 52 can be associated with the displacement direction of the tightening plate 58, and the scale set on the strip groove 500 is also helpful for the staff to judge the position of the tightening plate 58. At the same time, considering that the correction disk 50 adopts a solid structure and may have the problem of being too heavy, the correction disk 50 can adopt a large number of hollow structures in actual applications.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
