TECHNICAL FIELD
[0001] The application relates to the technical field of gear tooth measurement, and particularly relates to a gear tooth size rapid measurement device. BACKGROUND
[0002] Gear and gear products are important basic parts of mechanical equipment, and have a very large effect on the overall power system. Most of the main transmission components of complete mechanical equipment are gear transmissions. The quality of gears directly affects the service life and safe production of machines, and the precision of gears has an important influence on the performance of mechanical products. Therefore, improving gear detection technology is a necessary guarantee for improving the quality of gear products.
[0003] In actual application, the existing gear tooth size rapid measurement device often has problems of insufficient measurement accuracy and comprehensiveness because the measured gear cannot be cleaned synchronously. After the gear is processed, a large amount of processing debris, cooling liquid residues, dust and other foreign matters are inevitably attached to the surface of the gear. If the foreign matters are not removed in time, the measurement result will be directly interfered.
[0004] For example, the debris on the tooth surface may cause the measurement probe to misjudge the tooth thickness, and the oil stains at the tooth root may affect the light reflection of the optical measurement system, thereby causing data deviation. Meanwhile, the distribution of the foreign matters is often random, and the key parameters (such as the pitch and tooth profile error) of some gear teeth may be hidden, so that the device cannot fully capture the real processing state of the gear, and the risk of unqualified products flowing into the subsequent process is increased.
[0005] Therefore, the application provides a gear tooth size rapid measurement device. SUMMARY

[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] Please see Figures 1-7 A rapid gear tooth size measuring device includes a frame 1, with a support frame 3 mounted on the top of the frame 1; it also includes a servo motor 4 mounted outside the support frame 3, a rotating rod 5 fixedly connected to the power output shaft of the servo motor 4, a connecting plate 8 slidably connected to the outer edge of the rotating rod 5, one end of a return spring 9 fixedly connected to the outer side of the connecting plate 8, and a connecting plate 10 fixedly connected to the other end of the return spring 9, which is also slidably connected to the outer edge of the rotating rod 5; a plurality of gears 11 to be measured are slidably connected to the outer edge of the rotating rod 5; a drive unit mounted outside the support frame 3; a cleaning component mounted outside the frame 1; a measuring component mounted outside the support frame 3 for detecting the gears 11 to be measured; and an adjustment component mounted inside the frame 1.
[0030] In this scheme, the push force of the reset spring 9 to push the connecting plate 10 can facilitate the synchronous detection of different numbers of gears 11 under test, and can ensure that different numbers of gears 11 under test will not easily detach when measured synchronously.
[0031] For further details, please refer to [link / reference]. Figure 5 and Figure 6 A stud 6 is fixed at the end of the rotating rod 5 away from the servo motor 4, and a nut 7 is threadedly connected to the outer edge of the stud 6. The rotating rod 5 is rotatably connected to the outer edge of the support frame 3.
[0032] In this solution, the nut 7 can act as abutment for multiple gears 11 under test, thereby ensuring that multiple gears 11 under test can be stably installed on the outside of the rotating rod 5, ensuring that the gears 11 under test will not easily shake when the rotating rod 5 drives the gears 11 under test to rotate, and can fit tightly and not easily separate.
[0033] For further details, please refer to [link / reference]. Figure 5 and Figure 6 The cleaning assembly includes a rotating shaft 15, which is rotatably connected to the inner wall of the support frame 3. A cleaning roller 16 is installed on the outer edge of the rotating shaft 15. One end of an air pipe 17 is inserted into the inner wall of the rotating shaft 15. An air pump 18 is installed on the outer edge of the air pipe 17 and is fixedly connected to the outer wall of the support frame 3. Multiple air holes are opened on the outer edge of the cleaning roller 16. A limit ring is installed on the inner wall of the support frame 3, and the rotating shaft 15 is rotatably connected to the inner wall of the limit ring.
[0034] In order to position the air tube 17, a positioning frame 19 is installed on the outer wall of the support frame 3, and the air tube 17 is fixed to the inner wall of the positioning frame 19.
[0035] In this solution, the rotating shaft 15 drives the cleaning roller 16 to rotate, which in turn causes the cleaning roller 16 to rotate against the outside of the gear 11 being tested, thereby cleaning the gear 11 and ensuring that the surface of the gear 11 is clean and free from impurities. At the same time, the air pump 18 can be driven to deliver external air through the air pipe 17 to the inside of the rotating shaft 15, and then the air holes can be used to blow air onto the gear 11 being tested, which can further blow away the dust on the surface of the gear 11 and achieve thorough cleaning. Furthermore, the limiting ring can be used to ensure the stability of the rotating shaft 15 during rotation, ensuring that it will not easily shift or wobble during rotation.
[0036] For further details, please refer to [link / reference]. Figures 5-7 The drive unit includes a drive wheel 12 and a driven wheel 13. The drive wheel 12 is mounted on the outer edge of the rotating rod 5, and the driven wheel 13 is mounted on the outer edge of the rotating shaft 15. The inner walls of the drive wheel 12 and the driven wheel 13 are fitted with a transmission belt 14, so that when the drive servo motor 4 drives the rotating rod 5 to rotate, the drive wheel 12 and the transmission belt 14 can transmit the rotational force to the driven wheel 13, thereby synchronously driving the rotating shaft 15 and the cleaning roller 16 to rotate. Furthermore, it can realize the synchronous rotation of the gear under test 11 and the cleaning roller 16, which is convenient for detecting the teeth of the gear under test 11 at different positions, and also facilitates the cleaning roller 16 to clean different positions of the gear under test 11.
[0037] For further details, please refer to [link / reference]. Figure 7 The measuring component includes a bracket 33, which is mounted on the outer wall of the support frame 3. A rotary motor 20 is mounted on the outer wall of the support frame 3. A lead screw 21 is fixedly connected to the power output shaft of the rotary motor 20. A slider 22 is threadedly connected to the outer edge of the lead screw 21. A measuring device 25 is mounted on the top of the slider 22. A return spring 24 is sleeved on the outer edge of the lead screw 21.
[0038] In order to limit the slider 22 and make it move smoothly within the inner wall of the bracket 33, a limit rod 23 is installed on the inner wall of the bracket 33, and the slider 22 is slidably connected to the limit rod 23.
[0039] In this scheme, by driving the rotary motor 20 to rotate the lead screw 21, the slider 22 can be moved along the trajectory of the lead screw 21, thereby realizing the position adjustment of the measuring device 25. Furthermore, the measuring device 25 can be used to simultaneously detect multiple gears 11 under test, and the return spring 24 can be used to ensure that the slider 22 can be quickly reset to the initial position when it moves to the farthest end.
[0040] For further details, please refer to [link / reference].Figure 3 and Figure 4 The adjustment component includes a stepper motor 26, which is mounted on the inner top of the support frame 3. The power output shaft of the stepper motor 26 is fixedly connected to a threaded rod 27. The outer edge of the threaded rod 27 is threadedly connected to a lifting plate 28. Four moving wheels 29 are symmetrically installed at the bottom of the lifting plate 28.
[0041] In this solution, the stepper motor 26 drives the threaded rod 27 to rotate, which in turn adjusts the lifting plate 28 to drive the moving wheel 29 to move up and down. Thus, when the device does not need to move, the moving wheel 29 can be stored inside the frame 1, so that it does not need to contact the ground and bear the pressure of the device's own weight, thereby further improving the service life of the moving wheel 29.
[0042] For further details, please refer to [link / reference]. Figure 3 and Figure 4 Four uprights 30 are installed on the inner wall of the frame 1, and the bottom of the four uprights 30 is fixedly connected to the chassis 31. The lifting plate 28 is slidably connected to the four uprights 30. Each upright 30 is fitted with a push spring 32 on its outer edge, and the two ends of the push spring 32 abut against the top of the lifting plate 28 and the inner top of the frame 1, respectively.
[0043] In this design, the upright 30 can be used to limit the vertical movement of the lifting plate 28, further ensuring that the lifting plate 28 moves continuously in a vertical state. Furthermore, the chassis 31 can be used to abut the lifting plate 28, ensuring that the lifting plate 28 cannot move to the point of disengaging from the threaded rod 27. At the same time, the elastic restoring force of the push spring 32 can be used to improve the speed of the downward movement of the lifting plate 28 and the moving wheel 29.
[0044] For further details, please refer to [link / reference]. Figure 1 and Figure 7 A display 2 is mounted on the top of the frame 1, and the display 2 and the measuring instrument 25 are electrically connected.
[0045] In this solution, the measuring device 25 can be used to record and detect the tooth status of multiple sliders 22 in real time, and then the technical data can be transmitted to the display 2. The display 2 can be used to record and compare the tooth data, which can further facilitate the screening of the tested gear 11 with damaged teeth, thus improving the accuracy of the measurement data.
[0046] Working principle
[0047] First, multiple gears 11 to be tested can be inserted through the outside of the rotating rod 5. Then, the nut 7 can be threaded to the outer edge of the stud 6 until the nut 7 abuts against the outer wall of the outermost gear 11 to be tested. By driving the rotary motor 20 to drive the lead screw 21 to rotate, the slider 22 can be driven to move along the trajectory of the lead screw 21, thereby realizing the position adjustment of the measuring device 25. Furthermore, the measuring device 25 can be used to simultaneously detect multiple gears 11 to be tested.
[0048] Then, when the servo motor 4 drives the rotating rod 5 to rotate, the driving wheel 12 and the transmission belt 14 can transmit the rotational force to the driven wheel 13, which can then synchronously drive the rotating shaft 15 and the cleaning roller 16 to rotate. This further enables the gear under test 11 and the cleaning roller 16 to rotate synchronously, which facilitates the detection of teeth at different positions of the gear under test 11 and makes it easier for the cleaning roller 16 to clean different positions of the gear under test 11.
[0049] Finally, the drive unit, in conjunction with the rotating shaft 15, drives the cleaning roller 16 to rotate, which in turn causes the cleaning roller 16 to rotate against the outside of the gear 11 being tested. This allows for cleaning of the gear 11, ensuring that its surface is clean and free from impurities. Simultaneously, the air pump 18 is driven to deliver external air through the air pipe 17 to the inside of the rotating shaft 15. The air is then blown onto the gear 11 through the air holes, further removing dust from its surface and achieving thorough cleaning.
