Description

Technical Field

[0001] This invention relates to the field of gear testing technology, specifically to a gear runout tester for testing finished gears. Background Technology

[0002] Gear runout testers measure the runout of gears to assess geometric and installation errors during rotation. A simpler type uses a dial indicator, where the dial indicator's probe is inserted into the tooth groove for measurement. Multiple points on the same gear are tested to complete the runout measurement. This method is relatively simple to operate and has low equipment costs. However, it has some drawbacks. The position and diameter of the locating pin used for gear positioning cannot be adjusted, making it unsuitable for gears of different sizes. Furthermore, the size of the probe is also unadjustable, making it unsuitable for tooth grooves of different sizes. Therefore, different testers are needed for different gear sizes, making the operation cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a gear runout detector for finished gear inspection, so as to solve the problem mentioned in the background art that existing gear runout detectors cannot perform runout detection on gears of different sizes.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A gear runout detector for inspecting finished gears includes: a testing worktable, on which a support boss is fixedly mounted for gear runout detection; An adjustable gear limit assembly is installed on a testing workbench and can be adjusted according to the size of the gear to be tested. The adjustable gear detection assembly is also mounted on the detection workbench and is movably connected to the adjustable gear limiting assembly. The adjustable gear limiting assembly drives the adjustable gear detection assembly to move, thereby realizing the adjustment of the adjustable gear detection assembly. An anti-motion component is provided, which cooperates with the adjustable gear limiting component to fix the adjustable gear limiting component and ensure the stability of the adjustable gear limiting component and the adjustable gear detection component during the detection process.

[0005] Furthermore, the adjustable gear limiting assembly includes an operating stud, which is movably mounted on the testing worktable; An adjusting block is threadedly fitted onto an operating stud, and the adjusting block moves as the operating stud rotates. An adjustable support frame is movably mounted on an adjustable support block and connected to the testing workbench.

[0006] Furthermore, the adjusting block moves, causing the adjusting bracket to move as well.

[0007] Furthermore, a support vertical plate is fixedly provided at the lower end of the adjusting block, a matching roller is installed at the lower end of the support vertical plate, and a first connecting strip is fixedly provided on the support vertical plate.

[0008] Furthermore, a first limiting post is fixedly provided on the adjusting support, a second limiting post is fixedly provided at the upper end of the first limiting post, and a third limiting post is fixedly provided at the upper end of the second limiting post. Different limit pins are used to limit the movement of gears of different sizes, ensuring the smooth operation of gear runout detection.

[0009] Furthermore, the adjustable gear inspection assembly includes a rotary adjustment shaft, which is movably mounted on the inspection worktable; A movable connecting rod is movably mounted on a rotary adjusting shaft.

[0010] Furthermore, an adjustment ring frame is fixedly provided at the upper end of the rotary adjustment shaft, and a dial indicator is fixedly installed on the adjustment ring frame to detect the runout of the gear.

[0011] Furthermore, the rotary adjustment shaft is movably connected to the first connecting strip plate via a movable connecting rod, and the rotary adjustment shaft is driven to rotate by the adjusting support block.

[0012] Furthermore, the anti-movement component is a locking support plate, which is movably installed at the lower end of the testing workbench, and a locking support strip is fixedly installed on the locking support plate.

[0013] Furthermore, the locking bearing bar cooperates with the support vertical plate to lock the adjusting bearing block.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. The limiting pins used for gear positioning are set on the adjusting bracket. The position of the adjusting bracket can be changed, and multiple limiting pins are set on the adjusting bracket to correspond to gears of different sizes. When adjusting the adjusting bracket, simply rotate the operating stud to complete the position adjustment, so as to adapt to the runout detection of gears of different sizes, which is very convenient.

[0015] 2. When adjusting the support frame, the movement of the adjusting block can drive the rotating adjusting shaft to rotate, which in turn can drive the dial indicator on the adjusting ring frame to move. The measuring ball on each dial indicator is of different size, and the corresponding dial indicator can be rotated to the working position to adapt to different gears for runout detection. It can realize the synchronous adjustment of the measuring ball and the limit column, which is highly efficient and practical.

[0016] 3. In addition, when the adjusting block moves to the working position, it can be automatically locked by the locking plate to ensure the accuracy of its position adjustment and the stability of the adjusting frame during gear detection after the position adjustment is completed, thus ensuring the smooth progress of gear runout detection.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a technical solution: like Figure 1 , Figure 2 and Figure 3 As shown, a gear runout detector for finished gear inspection includes: a testing worktable 1, an adjustable gear limiting component, an adjustable gear detection component, and an anti-movement component. A support boss 11 is welded and fixed on the testing worktable 1. The surface of the support boss 11 is smooth and burr-free. Gear runout detection is performed on the support boss 11, that is, the support boss 11 supports the gear to be tested. The adjustable gear limiting component is installed on the testing worktable 1. The adjustable gear limiting component is adjusted according to the size of the gear to be tested so that the adjustable gear limiting component is adapted to the gear and limits the gear.

[0030] The adjustable gear detection component is also mounted on the detection workbench 1 and is movably connected to the adjustable gear limit component. The adjustable gear limit component drives the adjustable gear detection component to move, thereby adjusting the adjustable gear detection component so that it can be matched with the gear to perform runout detection. The anti-movement component cooperates with the adjustable gear limit component to fix the adjustable gear limit component, ensuring the stability of the adjustable gear limit component and the adjustable gear detection component during the detection process, thereby ensuring the accuracy of gear runout detection.

[0031] like Figure 4 and Figure 8 As shown, an operating channel 12 is provided on the inspection workbench 1. A first assembly hole 13 is provided on the inner wall of the operating channel 12 near the support boss 11. A second assembly hole 14 is provided on the inspection workbench 1 next to the support boss 11. In addition, connecting strips 15 are symmetrically welded and fixed on the lower end surfaces of the inspection workbench 1 on both sides of the operating channel 12. Installation insertion holes 16 are symmetrically provided on the inspection workbench 1 between the connecting strips 15. A support plate frame 17 is welded and fixed on the lower end surface of the inspection workbench 1. A support boss 18 is welded and fixed on the support plate frame 17. A support roller 19 is installed on the support boss 18.

[0032] like Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, the adjustable gear limiting assembly includes: an operating stud 2, an adjusting block 3, and an adjusting bracket 4. The operating stud 2 is movably mounted on the testing workbench 1. Specifically, the operating stud 2 is located in the operating channel 12, and a first bearing 21 is sleeved on one end of the operating stud 2. No threads are provided at the position where the operating stud 2 and the first bearing 21 mate. The first bearing 21 is installed in the first mounting hole 13. The operating stud 2 is movably mounted on the testing workbench 1 through the mating of the first bearing 21 and the first mounting hole 13.

[0033] The adjusting block 3 is threaded onto the operating stud 2. The adjustment block 3 moves by rotating the operating stud 2. Specifically, the adjusting block 3 has a threaded bearing hole 31. The adjusting block 3 is movably installed on the operating stud 2 by the cooperation of the threaded bearing hole 31 and the operating stud 2, and the adjusting block 3 is in the operating channel 12.

[0034] In addition, limit slides 32 are symmetrically provided on both sides of the adjusting block 3, and the inner wall of the limit slides 32 is smooth and burr-free.

[0035] The adjusting support frame 4 is movably installed on the adjusting support block 3 and connected to the testing worktable 1. Specifically, the two sides of the adjusting support frame 4 are inserted into the limiting slide rails 32 on the adjusting support block 3, and the surface of the adjusting support frame 4 is smooth and burr-free. The adjusting support frame 4 is in contact with the inner wall of the limiting slide rail 32. The limiting slide rail 32 limits and guides the adjusting support frame 4, so that when the adjusting support frame 4 moves relative to the adjusting support block 3, it can only move up and down along the limiting slide rail 32. In addition, the connecting support plates 44 are symmetrically welded to the lower ends of both sides of the adjusting support frame 4. The supporting swing rods 45 are hinged to the connecting support plates 44. The upper end of the supporting swing rods 45 is hinged to the connecting strip frame 15. The movable connection between the adjusting support frame 4 and the testing worktable 1 is realized through the supporting swing rods 45.

[0036] When the adjusting block 3 moves, it can drive the adjusting frame 4 to move horizontally in sync with it. When the adjusting block 3 moves, under the action of the supporting swing rod 45, the adjusting frame 4 will move up and down relative to the adjusting block 3.

[0037] A support vertical plate 33 is welded and fixed to the lower end of the adjusting support block 3. The surface of the support vertical plate 33 is smooth and burr-free. A matching roller 34 is installed at the lower end of the support vertical plate 33. A first connecting strip plate 35 is also welded and fixed to the support vertical plate 33. A second connecting strip plate 36 is integrally formed and fixed to the end of the first connecting strip plate 35 away from the adjusting support block 3. A connecting hinge 37 is welded and fixed to the second connecting strip plate 36. In addition, the lower end face of the first connecting strip plate 35 contacts the support roller 19 on the support protrusion 18. The support roller 19 provides further support to the first connecting strip plate 35 to ensure its stability during movement.

[0038] The upper end of the adjusting bracket 4 is welded and fixed with a first limiting post 41. The surface of the first limiting post 41 is smooth and burr-free. The upper end of the first limiting post 41 is welded and fixed with a second limiting post 42. The surface of the second limiting post 42 is smooth and burr-free. The upper end of the second limiting post 42 is welded and fixed with a third limiting post 43. The surface of the third limiting post 43 is also smooth and burr-free. The diameters of the first limiting post 41, the second limiting post 42 and the third limiting post 43 increase sequentially to accommodate gears of different sizes and to match the tooth grooves on the gears. They limit the movement of the gears to be tested. In actual operation, the number of limiting posts can be changed according to production needs to cope with the runout detection of gears of various sizes.

[0039] Different limit posts correspond to gears of different sizes to ensure smooth gear runout detection. The size of the limit posts can be designed according to the actual size of the tooth grooves on the gear. In addition, when the adjusting block 3 moves away from the supporting boss 11, the supporting swing rod 45 will drive the adjusting bracket 4 to move downward relative to the adjusting block 3, thereby causing the first limit post 41, the second limit post 42, and the third limit post 43 to move downward, thus accommodating the detection of larger gears. When the adjusting block 3 moves closer to the supporting boss 11, the supporting swing rod 45 will drive the adjusting bracket 4 to move upward relative to the adjusting block 3, thereby causing the first limit post 41, the second limit post 42, and the third limit post 43 to move upward, thus accommodating the detection of smaller gears.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, the adjustable gear inspection assembly includes a rotary adjustment shaft 6 and a movable connecting rod 7. The rotary adjustment shaft 6 is movably mounted on the inspection worktable 1. Specifically, a second bearing 61 is sleeved on the rotary adjustment shaft 6 and installed in a second mounting hole 14. The rotary adjustment shaft 6 is movably mounted on the inspection worktable 1 through the cooperation between the second bearing 61 and the second mounting hole 14. The lower end of the rotary adjustment shaft 6 protrudes from the lower side of the inspection worktable 1, and the upper end of the rotary adjustment shaft 6 protrudes from the upper side of the inspection worktable 1.

[0041] The movable connecting rod 7 is movably mounted on the rotary adjustment shaft 6. Specifically, a support base 66 is welded to the lower end of the rotary adjustment shaft 6. The support base 66 is located below the inspection workbench 1, and a support strip 67 is integrally formed and fixed on the support base 66. A support cavity 68 is formed in the support strip 67, and the movable connecting rod 7 is inserted into the support cavity 68. The movable connecting rod 7 is movably mounted on the lower end of the rotary adjustment shaft 6 through the cooperation between the movable connecting rod 7 and the support cavity 68. The cooperation between the movable connecting rod 7 and the support cavity 68 provides support and limit for the movable connecting rod 7, so that the movable connecting rod 7 can only move along the support cavity 68.

[0042] In addition, a connecting hinge block 71 is welded and fixed to the end of the movable connecting rod 7 away from the rotation adjustment shaft 6 by welding process, and a hinge shaft 72 is inserted into the connecting hinge block 71.

[0043] An adjusting ring frame 62 is welded and fixed to the upper end of the rotary adjusting shaft 6. An assembly plate 63 is welded and fixed to the upper end of the adjusting ring frame 62. A dial indicator 64 is fixedly installed on the assembly plate 63. A test ball 65 is installed on the dial indicator 64. The size of the test ball 65 on each dial indicator 64 is different. The size of the test ball 65 is adapted to the tooth groove on different gears. When the runout of the gear is detected by the dial indicator 64, the test ball 65 is inserted into the tooth groove.

[0044] The rotary adjustment shaft 6 is movably connected to the first connecting plate 35 via the movable connecting rod 7. The rotary adjustment shaft 6 is driven to rotate by the adjusting support block 3. Specifically, the connecting hinge block 71 on the movable connecting rod 7 is hinged to the connecting hinge frame 37 on the second connecting plate 36 via the hinge shaft 72. When the adjusting support block 3 moves, it will drive the second connecting plate 36 to move synchronously, thereby driving the rotary adjustment shaft 6 to rotate via the movable connecting rod 7, thus realizing the adjustment of the dial indicator 64.

[0045] like Figure 3 and Figure 7 As shown, the anti-movement component is a locking plate 5, which is movably installed at the lower end of the inspection workbench 1. Specifically, mounting rods 51 are symmetrically welded to the locking plate 5 using a welding process. The mounting rods 51 are inserted into the mounting insertion holes 16 on the inspection workbench 1. The mounting insertion holes 16 guide and limit the mounting rods 51, thereby limiting the locking plate 5 so that it can only move up and down. In addition, a support spring 52 is sleeved on the mounting rod 51. The support spring 52 is located on the upper side of the locking plate 5, and the upper end of the support spring 52 is welded to the lower end surface of the inspection workbench 1 using a welding process. The lower end of the support spring 52 is welded to the locking plate 5 using a welding process. The locking plate 5 is movably installed below the inspection workbench 1 by means of the mounting rods 51 and the support spring 52.

[0046] A locking support strip 53 is integrally formed and fixed on the locking support plate 5. The surface of the locking support strip 53 is smooth and burr-free, and a locking groove 54 is provided on the locking support strip 53. The inner wall of the locking groove 54 is smooth and burr-free.

[0047] When the locking support bar 53 cooperates with the support vertical plate 33 to lock the adjusting support block 3, the mating roller 34 on the support vertical plate 33 is inserted into the locking groove 54, and the mating roller 34 contacts the inner wall of the locking groove 54. In this way, the support vertical plate 33 can be locked under the action of the locking groove 54, which in turn can lock the adjusting support block 3, so that the adjusting support block 3 cannot move. This also locks the operating stud 2 and the rotating adjusting shaft 6, ensuring the stability of the adjusting support frame 4 and the dial indicator 64.

[0048] When performing gear runout detection, the gear is limited by the cooperation of the tooth groove and the limiting post. When placing the gear, the detection ball 65 is inserted into the tooth groove of the gear, and then the gear is placed between the detection ball 65 and the limiting post. The gear runout is detected by dial indicator 64. The above operation is repeated to perform multi-point detection of the gear to complete the gear runout detection. The operation is simple, convenient and quick.

[0049] When the limit pin and detection ball 65 need to be adjusted according to the size of the gear, and when the runout detection of a larger gear is required, the locking bearing plate 5 is pushed down to disengage the mating roller 34 from the locking groove 54. This unlocks the adjustment block 3. Then, the operating stud 2 is rotated so that the adjustment block 3 moves away from the support boss 11 under the action of the thread. When the mating roller 34 is misaligned with the disengaged locking groove 54, the locking bearing plate 5 is released. Under the action of the support spring 52, the locking bearing plate 5 moves upward so that the upper end face of the locking bearing bar 53 contacts the mating roller 34. Then, as the operating stud 2 is rotated, the mating roller 34 on the support vertical plate 33 aligns with the next locking groove 54. This removes the restriction on the locking bearing plate 5, and it continues to move upward under the action of the support spring 52, so that the mating roller 34 is inserted into the locking groove 54 to lock the adjustment block 3.

[0050] As the adjusting block 3 moves away from the supporting boss 11, the distance between the adjusting bracket 4 and the connecting frame 15 decreases. Under the action of the supporting swing rod 45, the adjusting bracket 4 moves downward, causing the larger limiting post to move downward. This allows the larger limiting post to engage with the tooth groove on the larger gear, thus limiting the gear. At this point, the adjustment of the limiting post is completed, and the adjusting bracket 4 is also further away from the supporting boss 11 so that the larger gear can be placed.

[0051] In addition, when the adjusting block 3 moves away from the supporting boss 11, it will also drive the second connecting plate 36 to move synchronously. Under the action of the second connecting plate 36, the movable connecting rod 7 will rotate and move along the supporting cavity 68. As the movable connecting rod 7 rotates, since it is inserted into the supporting cavity 68, it will also drive the rotating adjusting shaft 6 to rotate. This will drive the adjusting ring frame 62 to rotate, so that the dial indicator 64 with the larger measuring ball 65 will rotate to the working position. This allows for the detection of larger gears and the matching of larger tooth grooves. This completes the synchronous adjustment of the limit post and the measuring ball 65. The operation is simple, convenient and quick.

[0052] When it is necessary to detect the runout of smaller gears, simply rotate the operating stud 2 in the opposite direction to move the adjusting block 3 closer to the supporting boss 11 to complete the adjustment. This method can adapt to the runout detection of gears of various sizes, making it highly practical and easy to operate.

[0053] The movement of the adjusting block 3 is controlled by the threaded engagement between the stud 2 and the adjusting block 3, making the movement of the adjusting block 3 more stable and the position adjustment more precise. Furthermore, after the position of the adjusting block 3 is adjusted, the adjusting block 3 is locked by the engagement of the locking groove 54 and the mating roller 34, so that the adjusting block 3 will not move due to operator error during gear testing, thus ensuring the stability of the adjusting block 3 during gear testing, as well as the stability of the first limit post 41, the second limit post 42, the third limit post 43 and the dial indicator 64, so that gear testing can be carried out smoothly.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
