[0001] This invention relates to the technical field of gear inspection, and in particular to a tooth surface roughness measuring device for gear production. Background Technology

[0002] As a fundamental component for transmitting power and motion, gears have the characteristics of a wide power range, high transmission efficiency, long service life, and safety and reliability, and have become an indispensable transmission component in many mechanical products. After the gears are processed, their surface roughness needs to be tested. As a key component in the mechanical transmission system, the surface roughness of the gears directly affects their transmission efficiency and service life.

[0003] A roughness measuring device is designed in the related technology, which includes a base and a clamp set on the base. A measuring instrument is also slidably set on the base, and the measuring instrument is connected to a measuring probe. When measuring a gear, the gear is first clamped and fixed, and then the measuring instrument is operated so that the measuring probe of the measuring instrument contacts the gear's contact surface. The operation of the measuring instrument drives the measuring probe to detect on the gear's contact surface.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: it requires manual operation of the fixture to fix the gears, the fixture needs to be operated frequently when inspecting different gears, it is not convenient to inspect gears in batches, it is not convenient to inspect different tooth surface positions on the gear, it requires a large amount of labor, and the inspection efficiency is low, so it needs to be improved. Summary of the Invention

[0005] To enable batch inspection of multiple gears, facilitate the inspection of different tooth surface positions on the gear surface, improve the automation level of inspection, and enhance inspection efficiency, this application provides a tooth surface roughness measuring device for gear production.

[0006] The tooth surface roughness measuring device for gear production provided in this application adopts the following technical solution: A tooth surface roughness measuring device for gear production includes a worktable and a measuring instrument mounted on the worktable. A set of support rods are symmetrically slidably arranged on the worktable, and a positioning rod is disposed between the support rods. Support blocks are fixedly mounted on the support rods, and the sidewalls of the positioning rods have support grooves for inserting the support rods. Each positioning rod includes a rotating rod and a set of connecting rods. The rotating rod is rotatably disposed between two connecting rods, and the support grooves are disposed on the connecting rods. A rotating component is disposed between the connecting rods and the rotating rod, and the rotating component drives the rotating rod to rotate between the connecting rods. A positioning block slides on the rotating rod, and a positioning component is provided on the rotating rod for driving the positioning block. The telescopic assembly for the extension and retraction of the block includes a sliding groove on the rotating rod, within which a slider is slidably mounted. A sliding assembly on the rotating rod drives the slider to slide within the groove. A clearance groove is formed on the surface of the slider, and a clamping block is rotatably mounted on the inner wall of the clearance groove. A torsion spring is provided at the rotatable connection between the clamping block and the clearance groove, and a guide surface is inclined on the surface of the clamping block. A horizontal lead screw slide rail is mounted on the worktable, and a testing platform is slidably mounted on the horizontal lead screw slide rail. The testing instrument is located on the testing platform, and a lifting platform is vertically mounted on the testing platform. The testing instrument is connected to a testing probe, which is located below the lifting platform.

[0007] By adopting the above technical solution, when batch testing the tooth surfaces of multiple gears, the support rod close to the clamping block is first slid away, causing the support block on the support rod to disengage from the support groove. At this time, another support rod supports the positioning rod. Then, multiple gears are fitted onto the rotating rod, and the gears slide on the rotating rod, abutting against the guide surface on the clamping block, causing the clamping block to rotate into the relief groove. This facilitates the sliding of multiple gears to be measured between the clamping block and the positioning block. Meanwhile, the torsion spring drives the clamping block to rotate outward from the relief groove, abutting against the inner wall of the relief groove. During operation, the support rod resets, causing the support block to be inserted into the support groove. The sliding component works first, causing the clamping block to slide towards the positioning block. The clamping block clamps and fixes several gears. Then, the lifting platform rises and falls, moving the detection probe and the gear surface. During surface contact testing, the rotating component drives the rotating rod to rotate, which in turn drives several gears on its surface to rotate simultaneously. The testing probe can test different tooth surfaces of the gears. When different gears need to be tested, the lifting platform and the horizontal lead screw slide rail drive the testing platform to slide, which can control the testing probe to measure gears at different positions on the rotating rod. After the measurement is completed, the telescopic component drives the positioning block to slide into the rotating rod. At this time, the support rod near the positioning block slides, causing the support block to disengage from the support groove. The sliding component then works, driving the clamping block to abut against the gear, automatically removing the measured gear from the positioning rod. This enables batch testing of multiple gears and facilitates testing of different tooth surface positions on the gears, improving the automation level and efficiency of the testing.

[0008] Preferably, the testing platform is provided with a lifting screw slide rail, the lifting platform is slidably mounted on the lifting screw slide rail, the bottom end of the lifting platform is provided with a mounting rod, the testing probe is rotatably mounted on the mounting rod, and the end of the mounting rod is provided with a first spring that abuts against the testing probe.

[0009] Preferably, a contact sensor is provided at the end of the mounting rod, the contact sensor is connected to a processor, the lifting screw slide rail is electrically connected to the processor, and the processor is used to control the lifting screw slide rail to stop working when the contact sensor detects pressure.

[0010] By adopting the above technical solution, during testing, the lifting screw slide rail drives the lifting platform to descend, and the lifting platform drives the detection probe to descend. When the detection probe contacts the gear, the lifting screw slide rail continues to drive the lifting platform to descend, and the detection probe will rotate between the mounting rod until the end of the detection probe touches the contact sensor. After the contact sensor detects the pressure, it controls the lifting screw slide rail to stop working. When the rotating component drives the rotating rod to rotate between the connecting rods, the first spring abuts against the detection probe, which can keep the detection probe in continuous contact with the gear tooth surface. The detection probe can rotate between the mounting rod during testing, so that the device can meet the measurement needs of different types of gears and improve the applicability of the device.

[0011] Preferably, the sliding assembly includes a first motor and a lead screw. The first motor is disposed inside a rotating rod, and the lead screw is rotatably disposed inside a sliding groove. The drive shaft of the first motor is connected to the lead screw, and the slider is threadedly connected to the lead screw.

[0012] By adopting the above technical solution, when it is necessary to drive the clamping block to slide towards the positioning block, the first motor drives the lead screw to rotate, the slider is guided by the slide groove, and the slider slides along the length of the slide groove on the surface of the lead screw. The slider drives the clamping block to slide together, which is convenient and quick to control.

[0013] Preferably, buffer pads are provided on the opposing surfaces of the positioning block and the clamping block, and a pressure sensor is provided between the clamping block and the buffer pad. The pressure sensor is connected to a controller, and the first motor is electrically connected to the controller. The controller is used to control the first motor to stop working when the pressure value detected by the pressure sensor reaches a preset value.

[0014] By adopting the above technical solution, when the sliding component drives the clamping block and positioning block to clamp multiple gears simultaneously, the processor controls the first motor to stop working when the pressure value detected by the pressure sensor reaches the preset value, which improves the automation level of the device. The buffer pad can protect the gears and improve the clamping and fixing effect of multiple gears.

[0015] Preferably, the rotating component includes a second motor and a rotating shaft. The rotating rod is rotatably connected to the end wall of the connecting rod via the rotating shaft. The second motor is fixedly installed inside one of the connecting rods, and the drive shaft of the second motor is connected to one of the rotating shafts.

[0016] By adopting the above technical solution, after the detection probe descends and contacts the gear tooth surface, the second motor drives the rotating shaft to rotate, which in turn drives the rotating rod to rotate between the connecting rods, and the rotating rod then drives several gears on its surface to rotate simultaneously.

[0017] Preferably, the telescopic assembly includes a telescopic cylinder, a guide wheel, a connecting rope, and a second spring. The rotating rod has a telescopic groove, the positioning block is slidably disposed in the telescopic groove, the second spring is disposed on the bottom wall of the telescopic groove and abuts against the bottom wall of the positioning block, the guide wheel is rotatably disposed in the rotating rod, the telescopic cylinder is fixedly disposed in the rotating rod, one end of the connecting rope passes through the second spring and is connected to the bottom wall of the positioning block, and the other end of the connecting rope passes around the guide wheel and is connected to the piston rod of the telescopic cylinder.

[0018] By adopting the above technical solution, when unloading after measurement, the piston rod of the telescopic cylinder retracts, and the telescopic cylinder pulls the positioning block through the connecting rope. The guide wheel rotates to guide the connecting rope, and the positioning block slides through the connecting rope, retracting the positioning block into the telescopic groove. At this time, the sliding component drives the clamping block to abut against the gear, which can remove the gear from the positioning rod, realizing automatic unloading after the test is completed. When measurement is required again, the piston rod of the telescopic cylinder extends, the second spring abuts against the positioning block, and drives the positioning block to slide out of the telescopic groove and reset. The control is convenient and the implementation cost is low.

[0019] Preferably, the end wall of the support block is provided with an arc surface.

[0020] By adopting the above technical solution, when the support rod is moved by the cylinder, it is easy for the support block to be inserted into the support groove, and the arc surface can play a guiding role.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up support rods, positioning rods, support blocks, support grooves, rotating rods, connecting rods, rotating parts, positioning blocks, telescopic components, sliding grooves, sliders, sliding components, clearance grooves, clamping blocks, torsion springs, guide surfaces, horizontal lead screw slides, detection tables, lifting tables, and detection probes, multiple gears are mounted on the rotating rod when batch testing the tooth surfaces of multiple gears. The sliding component works first, driving the clamping block to clamp and fix several gears. Then, the lifting table drives the detection probe to contact the gear surface. During testing, the rotating part drives the rotating rod to rotate, and the rotating rod drives several gears on its surface to rotate simultaneously. The detection probe can detect different tooth surfaces of the gears. By using the lifting platform to rise and the horizontal lead screw slide to drive the detection table to slide, the detection probe can be controlled to measure gears at different positions on the rotating rod, realizing batch testing of multiple gears. At the same time, it is convenient to detect different tooth surface positions of the gears, improving the automation level of the testing and enhancing the testing efficiency. 2. By setting up a lifting screw slide rail, mounting rod, first spring, and contact sensor, the lifting screw slide rail drives the lifting platform to descend during detection. When the detection probe contacts the gear, the detection probe will rotate between the detection probe and the mounting rod until the end of the detection probe touches the contact sensor. After the contact sensor detects the pressure, it controls the lifting screw slide rail to stop working. When the rotating component drives the rotating rod to rotate between the connecting rods, the first spring abuts against the detection probe, which can keep the detection probe in continuous contact with the gear tooth surface. The detection probe can rotate between the detection probe and the mounting rod during detection, so that the device can meet the measurement needs of different types of gears and improve the applicability of the device. 3. By setting up a telescopic cylinder, guide wheel, connecting rope, and second spring, when unloading after measurement, the piston rod of the telescopic cylinder retracts, and the telescopic cylinder pulls the positioning block through the connecting rope. The guide wheel rotates to guide the connecting rope, and the positioning block slides through the connecting rope, retracting the positioning block into the telescopic groove. At this time, the sliding component drives the clamping block to abut against the gear, which can remove the gear from the positioning rod, realizing automatic unloading after the test. When measurement is required again, the piston rod of the telescopic cylinder extends, the second spring abuts against the positioning block, and the positioning block slides out of the telescopic groove to reset. The control is convenient and the implementation cost is low. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a tooth surface roughness measuring device for gear production. (Refer to...) Figure 1 and Figure 2 The device includes a workbench 1 and a testing instrument 11. A set of support rods 2 are symmetrically slidably arranged on the workbench 1. The support rods 2 are arranged vertically and are slidably mounted on the surface of the workbench 1 by a cylinder. A positioning rod 21 is horizontally arranged between the support rods 2. A support block 22 is integrally set on the support rod 2. The support block 22 is arranged horizontally and has an arc surface on its end wall. The side wall of the positioning rod 21 has a support groove 221 for the support rod 2 to be inserted. The support groove 221 and the support block 22 are mutually adapted. When the support block 22 is inserted into the support groove 221, the support block 22 abuts against the inner wall of the support, and the support rod 2 can support the positioning rod 21.

[0029] Reference Figure 1 and Figure 2 The positioning rod 21 includes a rotating rod 211 and a set of connecting rods 212. The rotating rod 211 is rotatably disposed between the two connecting rods 212. A support groove 221 is disposed on the connecting rods 212. A rotating component 3 is disposed between the connecting rods 212 and the rotating rod 211. The rotating component 3 includes a second motor 31 and a rotating shaft 32. The rotating rod 211 is rotatably connected to the end wall of the connecting rod 212 through the rotating shaft 32. The second motor 31 is fixedly disposed in one of the connecting rods 212 by bolts. The drive shaft of the second motor 31 is interconnected with one of the rotating shafts 32. A positioning block 23 slides on the rotating rod 211. The positioning block 23 can slide into the rotating rod 211. A telescopic component 4 is disposed on the rotating rod 211 for driving the extension and retraction of the positioning block 23.

[0030] Reference Figure 2 and Figure 3 The rotating rod 211 has a groove 5 on its surface, and the length of the groove 5 is along the length of the rotating rod 211. A slider 51 is slidably disposed in the groove 5, and the slider 51 is adapted to the groove 5. A sliding component 6 is provided on the rotating rod 211 for driving the slider 51 to slide in the groove 5. The slider 51 has a clearance groove 52 on its surface, and a clamping block 521 is rotatably disposed on the inner wall of the clearance groove 52. A torsion spring is provided at the rotatable connection between the clamping block 521 and the clearance groove 52. The torsion spring drives the clamping block 521 to abut against the inner wall of the clearance groove 52 and to be located at the opening of the clearance groove 52. The clamping block 521 can be completely rotated into the clearance groove 52. A guide surface 5211 is inclined on the surface of the clamping block 521. Before measuring multiple gears simultaneously, slide the support rod 2 closer to the clamping block 521 to disengage the support block 22 on the support rod 2 from the support groove 221. At this time, another support rod 2 supports the positioning rod 21. Then, multiple gears are fitted onto the rotating rod 211. The gears slide on the rotating rod 211 and abut against the guide surface 5211 on the clamping block 521, causing the clamping block 521 to rotate into the relief groove 52, facilitating the placement of multiple gears to be measured. The gear slides between the clamping block 521 and the positioning block 23, while the torsion spring drives the clamping block 521 to rotate outward of the relief groove 52, and the clamping block 521 abuts against the inner wall of the relief groove 52; then the control rod 2 resets and drives the support block 22 to be inserted into the support groove 221, the sliding component 6 works, and drives the clamping block 521 to slide towards the positioning block 23. The clamping block 521 and the positioning block 23 clamp several gears and fix the multiple gears against the surface of the rotating rod 211.

[0031] Reference Figure 1 and Figure 2A horizontal lead screw slide rail 7 is fixedly installed on the workbench 1. The length direction of the horizontal lead screw slide rail 7 is set along the length direction of the positioning rod 21. A detection table 71 is slidably installed on the horizontal lead screw slide rail 7. A detector 11 is fixedly installed on the detection table 71. A lifting platform 72 is lifted and lowered on the detection table 71. A detection probe 111 is connected to the detector 11. The detection probe 111 is located below the lifting platform 72. After the gear is clamped and fixed by the sliding assembly 6, the lifting platform 72 rises and falls, causing the detection probe 111 to contact the gear surface. During detection, the rotating component 3 drives the rotating rod 211 to rotate, and the rotating rod 211 drives several gears on its surface to rotate simultaneously. The detection probe 111 can detect different tooth surfaces of the gear. When different gears need to be detected, the lifting platform 72 rises and falls, and the horizontal lead screw slide rail 7 drives the detection platform 71 to slide. This can control the detection probe 111 to contact the gears at different positions on the rotating rod 211. After the measurement is completed, the telescopic assembly 4 drives the positioning block 23 to slide into the rotating rod 211. At this time, the support rod 2 close to the positioning block 23 slides, causing the support block 22 to move away from the positioning rod 21. The sliding assembly 6 then works again, driving the clamping block 521 to abut against the gear, automatically removing the measured gear from the positioning rod 21, thus realizing the measurement of multiple gears at one time.

[0032] Reference Figure 1 A lifting screw slide rail 8 is fixedly installed on the detection table 71. The lifting screw slide rail 8 is arranged vertically. The lifting table 72 is slidably mounted on the lifting screw slide rail 8. A mounting rod 81 is fixedly installed at the bottom end of the lifting table 72. The detection probe 111 is rotatably mounted on the mounting rod 81 via a pin. A first spring 82 is fixedly installed at the end of the mounting rod 81 to abut against the detection probe 111. A contact sensor 83 is installed at the end of the mounting rod 81. The contact sensor 83 is connected to a processor. The lifting screw slide rail 8 is electrically connected to the processor. During testing, the lifting screw slide rail 8 drives the lifting platform 72 to descend, and the lifting platform 72 drives the detection probe 111 to descend. When the detection probe 111 contacts the gear, it will rotate between the detection probe 111 and the mounting rod 81. The lifting screw slide rail 8 continues to drive the lifting platform 72 to descend until the end of the detection probe 111 contacts the contact sensor 83. After the contact sensor 83 detects the pressure, the processor controls the lifting screw slide rail 8 to stop working. When the rotating component 3 drives the rotating rod 211 to rotate between the connecting rod 212, the first spring 82 abuts against the detection probe 111, which can keep the detection probe 111 in continuous contact with the gear tooth surface. The detection probe 111 can rotate between the detection probe and the mounting rod 81 during testing, so that the device can meet the measurement requirements of different types of gears and improve the automation and applicability of the device.

[0033] Reference Figure 2 and Figure 3The sliding assembly 6 includes a first motor 61 and a lead screw 62. The first motor 61 is fixedly mounted inside the rotating rod 211, and the lead screw 62 is rotatably mounted inside the slide groove 5. The length direction of the lead screw 62 is along the length direction of the rotating rod 211. The drive shaft of the first motor 61 is connected to the lead screw 62, and the slider 51 is threadedly connected to the lead screw 62. When it is necessary to drive the clamping block 521 to slide towards the positioning block 23, the first motor 61 drives the lead screw 62 to rotate. The slider 51 is guided by the slide groove 5 and slides along the length direction of the slide groove 5 on the surface of the lead screw 62. The slider 51 drives the clamping block 521 to slide together, making the control convenient and quick.

[0034] Reference Figure 3 A buffer pad 9 is provided on the opposite surface of the positioning block 23 and the clamping block 521. A pressure sensor is provided between the clamping block 521 and the buffer pad 9. The pressure sensor is connected to a controller. The first motor 61 is electrically connected to the controller. When the sliding component 6 drives the clamping block 521 and the positioning block 23 to clamp multiple gears at the same time, the processor controls the first motor 61 to stop working when the pressure value detected by the pressure sensor reaches the preset value, which improves the automation level of the device. The buffer pad 9 can protect the gears and improve the clamping and fixing effect of the gears, making it easier for the rotating rod 211 to drive the gears to rotate.

[0035] Reference Figure 2 and Figure 4 The telescopic assembly 4 includes a telescopic cylinder 41, a guide wheel 42, a connecting rope 43, and a second spring 44. A telescopic groove 231 is provided on the rotating rod 211. The positioning block 23 is slidably disposed in the telescopic groove 231 and is adapted to the telescopic groove 231. The second spring 44 is disposed on the bottom wall of the telescopic groove 231 and abuts against the bottom wall of the positioning block 23. The guide wheel 42 is rotatably disposed in the rotating rod 211. The telescopic cylinder 41 is fixedly disposed in the rotating rod 211. One end of the connecting rope 43 passes through the second spring 44 and is connected to the bottom wall of the positioning block 23. The other end of the connecting rope 43 passes around the guide wheel 42 and is connected to the piston rod of the telescopic cylinder 41. After the gear measurement is completed, the piston rod of the telescopic cylinder 41 retracts, and the telescopic cylinder 41 pulls the positioning block 23 through the connecting rope 43. The guide wheel 42 rotates to guide the connecting rope 43, and the positioning block 23 is retracted into the telescopic groove 231 through the connecting rope 43. At this time, the sliding component 6 drives the clamping block 521 to abut against the gear, which can remove the gear from the positioning rod 21, realizing automatic unloading after the test is completed. When it is necessary to measure again, the piston rod of the telescopic cylinder 41 extends, the second spring 44 abuts against the positioning block 23, and drives the positioning block 23 to slide out of the telescopic groove 231 to reset. The control is convenient and the implementation cost is low.

[0036] The implementation principle of the tooth surface roughness measuring device for gear production in this embodiment is as follows: When it is necessary to inspect the tooth surfaces of multiple gears, first slide the support rod 2 close to the clamping block 521 so that one of the support rods 2 disengages from the positioning rod 21. Then, the gears to be measured are sequentially mounted on the rotating rod 211. The gears slide on the rotating rod 211 and abut against the guide surface 5211 on the clamping block 521, causing the clamping block 521 to rotate into the relief groove 52, thus sliding the multiple gears to be measured... After being moved between the clamping block 521 and the positioning block 23, the first motor 61 operates, driving the slider 51 to slide within the slide groove 5, controlling the clamping block 521 to slide towards the positioning block 23. The clamping block 521 and the positioning block 23 are used to clamp and fix several gears. During testing, the support rod 2 resets, causing the support block 22 to be inserted into the support groove 221. The support rod 2 supports the positioning rod 21, and the lifting screw slide rail 8 drives the lifting platform 72 to rise and fall, causing the detection probe 111 to contact the gear tooth surface, thus initiating contact sensing. When the pressure signal is detected by the device 83, the processor lifting screw slide rail 8 stops working; then the second motor 31 drives the rotating rod 211 to rotate, and the rotating rod 211 drives several gears on its surface to rotate simultaneously. The detection probe 111 can detect different tooth surfaces of the gears. When different gears need to be detected, the lifting platform 72 is used to lift and the horizontal screw slide rail 7 drives the detection platform 71 to slide, which can control the detection probe 111 to measure the gears at different positions on the rotating rod 211. After the measurement is completed, the piston rod of the telescopic cylinder 41 moves through the connecting rope 43 to pull the positioning block 23 to slide into the telescopic groove 231. At this time, the support rod 2 close to the positioning block 23 slides, so that the support block 22 is disengaged from the support groove 221. The sliding component 6 then works, and the sliding component 6 drives the clamping block 521 to abut against the gear, automatically unloading the measured gear from the positioning rod 21. This realizes batch detection of multiple gears, and at the same time facilitates detection of different tooth surface positions on the gear surface, improving the automation level of detection and enhancing detection efficiency.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
