Description

Technical Field

[0001] The invention belongs to the technical field of grinding processing, and in particular relates to a clamping tool and a deburring device for small-module gears. Background Art

[0002] During the gear processing, due to cutting, grinding and other process operations, tiny metal particles or debris will be formed on the surface of the gear, which are called burrs. The presence of these burrs will not only reduce the surface quality of the gear and increase the surface roughness, but also significantly affect the transmission efficiency, service life and overall performance of the gear. Therefore, it is very important to completely remove the burrs on the gear.

[0003] In order to remove gear burrs efficiently and accurately, modern industry often uses turntable deburring equipment. This equipment is equipped with multiple gear processing platforms in the circumferential direction of the turntable, and each platform is used to place the gear to be processed. When the turntable rotates, the position of the gear to be processed on the turntable can be easily changed for the next step of processing.

[0004] However, in the existing turntable deburring equipment, when the gear to be processed rotates to the processing position, the driving component is usually required to drive the fixing rod to move vertically downward from the top of the gear to be processed until the top of the gear is pressed and fixed. Although this fixing method can fix the gear to a certain extent, every time a new gear to be processed is transferred to the processing position, the driving component needs to be started separately to perform the fixing action. Such an operation process undoubtedly increases the complexity of the entire processing process and the inconvenience in operation. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a clamping tool and a deburring device for small-module gears, so as to solve the technical problem that when a new gear to be processed is transferred to the processing position, a driving component needs to be separately started to perform a fixing action, resulting in complicated operation.

[0006] One of the present inventions: To achieve the above-mentioned invention object, the technical solution adopted by the present invention includes: a clamping tool for small modulus gears, including a turntable rotatably arranged on a body and a plurality of placement tables fixed on the turntable, the top of the placement table has a horizontal placement surface, a hollow limiting portion is fixed on the placement surface, a mounting hole is opened on the side wall of the limiting portion, a fixing block is movably connected in the mounting hole, and the fixing block has a pressing portion; The placing table is provided with a push rod, the upper end of which extends upward into the limiting part, and the lower end of which extends downward to pass through the placing table. A lifting part fixed to the main body is also provided below the turntable. The push rod can be moved to the lifting part by rotating the turntable, and move upward under the lifting action of the lifting part. The upward movement of the push rod will push the fixed block to move toward the top surface of the gear to be processed so that the pressing part of the fixed block gradually presses the gear to be processed. The clamping tool also includes an elastic component, which is used for resetting the fixing block and the ejector rod.

[0007] Compared with the prior art, the advantages of the present invention include: (1) The present invention provides a clamping tool for small-module gears. By cleverly rotating a turntable, the push rod can be driven to move smoothly to the lifting part. Under the lifting action of the lifting part, the push rod will move upward steadily, thereby pushing the fixing block to gradually approach the top surface of the gear to be processed, thereby achieving a stable fixation of the gear to be processed. This mechanical transmission method is not only simple and reliable, but also easy to realize automatic control, which significantly improves production efficiency.

[0008] (2) The present invention provides a clamping tool for small-module gears. Compared with the existing turntable deburring equipment, the clamping tool provided by the present invention not only fixes the gears, but also further simplifies the operation process. Whenever a new gear to be processed is transmitted to the processing position, there is no need to separately start complex driving components to perform tedious fixing actions. The staff only needs to simply turn the turntable and use the lifting part to push the push rod up, so that the clamping part of the fixing block can approach and press the gear to be processed. The whole operation process is simple and convenient.

[0009] (3) The present invention provides a clamping tool for small-module gears. The present invention also performs well in releasing the fixation of the gear to be processed. The staff only needs to continue to rotate the turntable to allow the push rod to smoothly detach from the lifting part. At this time, under the action of the elastic component, the fixing block and the push rod will quickly elastically reset, thereby easily releasing the fixation of the gear to be processed. Whether fixing or releasing the fixation, it is achieved by the simple action of rotating the turntable. This design enables the gear to be fixed or released synchronously during the process of rotating the turntable to switch to the next gear to be processed, thereby greatly improving the overall work efficiency.

[0010] Furthermore, the fixing block is rotatably arranged in the mounting hole via a rotating shaft; The elastic component includes a torsion spring and a first spring. The torsion spring is installed on the rotating shaft to drive the fixed block to elastically reset. When the torsion spring is in a natural state, the fixed block is located in the mounting hole. The first spring is sleeved on the outside of the push rod. One end of the first spring is connected to the push rod, and the other end is connected to the placement table.

[0011] Furthermore, the lifting part is a block structure, the top of the lifting part has a horizontal supporting surface, both sides of the supporting surface have inclined surfaces that can drive the push rod to move in the vertical direction, and the two inclined surfaces and the supporting surface combine to form a structure with a trapezoidal cross-section.

[0012] Furthermore, the bottom of the push rod is a hemispherical contact portion.

[0013] In the present invention, the hemispherical contact portion enables the push rod to actually make contact at a very small point when it contacts the supporting surface of the lifting portion. This point contact characteristic reduces the contact area, thereby reducing friction. Moreover, due to the small contact area, the push rod is more likely to slide when pushed by the inclined surface, which helps to achieve a smoother lifting and lowering movement. In addition, since the hemispherical contact has a spherical surface, the push rod can better rise or descend along the inclined surface, thereby improving the smoothness of the movement of the push rod.

[0014] Furthermore, the support surface has a spherical recessed portion, the diameter of the recessed portion is larger than the diameter of the contact portion, and when the gear to be processed is transferred to the processing position, the contact portion is located in the recessed portion and abuts against the bottom of the recessed portion.

[0015] Furthermore, the outer wall of the limiting portion is provided with a protrusion matching the keyway of the gear to be processed, and the protrusion is located in the keyway of the gear to be processed and is used to limit the rotation of the gear to be processed.

[0016] Furthermore, the pressing part is made of rubber material.

[0017] The second of the present invention: A deburring device, comprising: Bracket; The clamping tool, the lifting part is fixed on the bracket, the turntable is rotatably connected to the bracket, the placement platform is a round rod-shaped structure, and the placement platform is rotatably connected to the turntable; A tooth groove cleaning component, the tooth groove cleaning component comprises a brush wheel and a first driving member, the first driving member is mounted on a bracket, an output shaft of the first driving member is connected to the axis of the brush wheel, and when the push rod contacts the recessed portion of the jacking portion, the brush wheel contacts the gear to be processed; A first transmission assembly is provided between the first driving member and the placement table. When the push rod contacts the recessed portion of the lifting portion, the first driving member can drive the placement table to rotate through the first transmission assembly, thereby driving the gear to be processed to rotate.

[0018] In the present invention: (1) Through the first transmission assembly, when the push rod contacts the recessed portion of the lifting portion, the first driving member can drive the placement table to rotate, thereby driving the gear to be processed to rotate. At the same time, the first driving member will also rotate the brush wheel synchronously. The brush wheel rotates to clean the tooth grooves of the gear to be processed. Since the gear to be processed is rotating, the brush wheel can achieve comprehensive cleaning of the tooth grooves of the gear to be processed, further improving the cleaning effect.

[0019] (2) When the push rod is not in contact with the recessed portion of the lifting portion, the first transmission assembly does not function, that is, the first driving member cannot drive the placement table to rotate, and the placement table does not rotate, which facilitates the subsequent removal of the processed gear.

[0020] Furthermore, the deburring device also includes a controller and a sensor, and the controller is signal-connected to the sensor and the first driving member. The sensor is arranged in the recessed portion. When the push rod moves into the recessed portion, the sensor transmits a signal to the controller, and the controller controls the start-up of the first driving member. When the push rod moves out of the recessed portion, the sensor transmits a signal to the controller, and the controller controls the shutdown of the first driving member.

[0021] Further, the deburring device further comprises a tooth surface cleaning component, the tooth surface cleaning component comprises a cleaning tool and a second driving component, the cleaning tool has two cleaning edges, the two cleaning edges respectively abut against the upper and lower side surfaces of the gear to be processed, and the second driving component is used to drive the cleaning tool away from or close to the gear to be processed so that the two cleaning edges contact or disengage with the upper and lower side surfaces of the gear to be processed; A second transmission assembly is provided between the second driving member and the rotating disk, and the second transmission assembly only allows the second driving member to drive the cleaning tool away from the gear to be processed and drive the rotating disk to rotate.

[0022] In the present invention: (1) Through the second transmission assembly, the tooth surface cleaning work of the gear to be processed is linked with the replacement of the gear to be processed, which simplifies the operation process.

[0023] (2) The turntable can be rotated in one direction by the second transmission assembly. During the one-way rotation of the turntable, the gear to be processed can be switched, so that the burr cleaning work of the gear to be processed can be carried out continuously, thereby improving efficiency.

[0024] (3) Through the second transmission assembly, the second drive member can simultaneously drive the turntable to rotate while driving the cleaning tool away from the gear to be processed. Conversely, the second drive member cannot drive the turntable to rotate while driving the cleaning tool close to the gear to be processed. This design realizes intermittent unidirectional rotation of the turntable. When the turntable rotates, the gear to be processed can be switched. When the turntable does not rotate, burr cleaning is performed. The cleaning process is compact and the efficiency is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] One of the present inventions: See also Figure 1-3 The present invention provides a technical solution: a clamping tool for small module gears, see Figure 3, including a turntable 3 rotatably arranged on a body (the body is a bracket 1 of the deburring equipment) and a plurality of placement tables 2 fixed on the turntable 3. The rotation of the turntable 3 can drive the plurality of placement tables 2 fixed thereon to rotate together. The placement table 2 has a horizontal placement surface on the top, and the placement surface is used to place a small modulus gear to be processed (hereinafter referred to as the gear 4 to be processed). A hollow limiting portion 5 is fixed on the placement surface, and the limiting portion 5 is located on the inner side of the gear 4 to be processed. A mounting hole 6 is opened on the side wall of the limiting portion 5, and a fixing block 7 is movably connected in the mounting hole 6. The fixing block 7 has a clamping portion 8, and the clamping portion 8 is used to clamp the gear 4 to be processed.

[0034] A push rod 9 is arranged through the placement table 2, and the upper end of the push rod 9 extends upward into the limiting portion 5, and the lower end extends downward to pass through the placement table 2. A lifting portion 34 fixed to the main body is also arranged below the turntable 3. The push rod 9 can be moved to the lifting portion 34 by rotating the turntable 3, and move upward under the pushing action of the lifting portion 34. The upward movement of the push rod 9 will push the fixed block 7 to move toward the top surface of the gear 4 to be processed so that the clamping portion 8 of the fixed block 7 gradually presses the gear 4 to be processed.

[0035] The clamping tool also includes an elastic component, which is used to reset the fixing block 7 and the ejector rod 9.

[0036] Place multiple gears 4 to be processed on multiple placement tables 2 respectively, and make the gears 4 to be processed sleeved on the outside of the limiting part 5. Rotate the turntable 3 to move one of the push rods 9 to the top of the lifting part 34, and the lifting part 34 lifts the push rod 9 to make it move upward. During the upward movement of the push rod 9, the fixed block 7 is pushed to move toward the top surface of the gear 4 to be processed, and the clamping part 8 of the fixed block 7 gradually clamps the gear 4 to be processed to achieve clamping. After the deburring work is completed, continue to rotate the turntable 3 to make the push rod 9 disengage from the lifting part 34, and the fixed block 7 and the push rod 9 are elastically reset under the action of the elastic component, thereby releasing the clamping of the gear 4 to be processed, and continue to rotate the turntable 3 until the lifting part 34 contacts the next push rod 9, and repeat this cycle to achieve continuous burr cleaning work.

[0037] Compared with the existing turntable 3 type deburring equipment, it can further simplify the operation process and make it easy to operate under the premise of fixing the gear. That is, every time a new gear 4 to be processed is transferred to the processing position, there is no need to start the driving component separately to perform the fixing action. It is only necessary to rotate the turntable 3, and then push the push rod 9 upward under the action of the lifting part 34 and make the pressing part 8 of the fixed block 7 close to the gear 4 to be processed to achieve pressing. Subsequently, the turntable 3 is continued to be rotated to make the push rod 9 disengage from the lifting part 34, and the fixed block 7 and the push rod 9 are elastically reset under the action of the elastic component, thereby releasing the pressing of the gear 4 to be processed. Such operation reduces the complexity of the entire processing process and the inconvenience in operation.

[0038] See also Figure 3 In this embodiment: the fixed block 7 is rotatably arranged in the mounting hole 6 through the rotating shaft. The fixed block 7 is similar to an L-shape. The rotating shaft is arranged in the middle of the fixed block 7. One end of the fixed block 7 serves as a clamping end. The clamping part 8 is arranged on the clamping end. When the fixed block 7 rotates, the clamping end rotates together with it. The clamping part 8 gradually approaches the top surface of the gear 4 to be processed, and the clamping is gradually achieved. The other end of the fixed block 7 serves as a prying end. When the prying end is pushed by an external force, the fixed block 7 can be rotated (that is, the push rod moves upward to push the prying end to rotate, so as to rotate the fixed block).

[0039] The elastic component includes a torsion spring 10 and a first spring 11. The torsion spring 10 is installed on the rotating shaft to drive the fixed block 7 to return to its original position elastically. A limiting column is provided in the mounting hole 6. One torsion arm of the torsion spring 10 is fixedly connected to the fixed block 7, and the other torsion arm abuts against the limiting column. When the torsion spring 10 is in a natural state, the fixed block 7 is located in the mounting hole 6. Since the fixed block 7 is located in the mounting hole 6 at this time, when the gear 4 to be processed is placed in the limiting portion 5, the interference caused by the fixed block 7 on the gear 4 to be processed can be reduced, thereby making it more convenient to place the gear 4 to be processed. The first spring 11 is sleeved on the outside of the push rod 9. One end of the first spring 11 is connected to the push rod 9, and the other end is connected to the placement table 2.

[0040] When the push rod 9 moves upward, it pushes the prying end of the fixed block 7 (the part located inside the limiting part 5), causing the fixed block 7 to rotate around the rotating shaft. The rotation of the fixed block 7 causes its clamping end (the clamping part 8 is arranged at this end) to gradually approach and clamp the gear 4 to be processed. When the push rod 9 is no longer subjected to the jacking action of the lifting part 34, the elastic force of the torsion spring 10 begins to play a role, driving the fixed block 7 to elastically reset, so that the fixed block 7 returns to the mounting hole 6. In addition, when the push rod 9 is subjected to the jacking action of the lifting part 34, the first spring 11 will be compressed. When the lifting part 34 no longer lifts the push rod 9, the elastic force of the first spring 11 begins to release, pushing the push rod 9 to move downward, so that the push rod 9 is reset. The torsion spring 10 and the first spring 11 together constitute the elastic reset system of the clamping tool. The torsion spring 10 is responsible for the reset of the fixed block 7, while the first spring 11 is responsible for the reset of the push rod 9. The synergistic effect of the two ensures the stability and reliability of the clamping tool during the clamping and reset process.

[0041] See also Figure 1In this embodiment, the lifting part 34 is a block-shaped structure, and the top of the lifting part 34 has a horizontal support surface 12. When the push rod 9 is transferred to contact with the support surface 12, the push rod 9 abuts against the support surface 12, thereby maintaining the clamping state of the fixed block 7 on the gear 4 to be processed. There are inclined surfaces 13 on both sides of the support surface 12 that can drive the push rod 9 to move in the vertical direction. The two inclined surfaces 13 and the support surface 12 form a structure with a trapezoidal cross section. The design of the inclined surface 13 is the key. When the turntable 3 rotates and the push rod 9 gradually approaches the lifting part 34, the push rod 9 will first contact the lower end of the inclined surface 13. As the turntable 3 continues to rotate, the push rod 9 will gradually rise along the inclined surface 13. When the push rod 9 completely passes through the inclined surface 13 and reaches the support surface 12, it will reach its highest position. At this time, the fixed block 7 has been pushed to the position of clamping the gear 4 to be processed. When the turntable 3 continues to rotate and the push rod 9 gradually leaves the lifting part 34, the elastic force of the first spring 11 will begin to play a role, pushing the push rod 9 to return downward. At this time, the inclined surface 13 will play a guiding role to ensure that the push rod 9 can smoothly descend along the inclined surface 13. The structural design with a trapezoidal cross section not only provides a stable supporting surface 12, but also realizes the smooth lifting and lowering of the push rod 9 through the inclined surface 13. This design also makes the lifting part 34 more compact in structure, which is conducive to reducing the volume and weight of the entire clamping tool.

[0042] See also Figure 1 In this embodiment: the bottom of the push rod 9 is a hemispherical contact portion 14. The hemispherical contact portion 14 makes the push rod 9 actually contact at a very small point when it contacts the support surface 12 of the lifting portion 34. This point contact characteristic reduces the contact area, thereby reducing the friction. And because the contact area is small, the push rod 9 is more likely to slide when pushed by the inclined surface 13, which helps to achieve a smoother lifting movement. In addition, because the hemispherical contact has a spherical surface, the push rod 9 can better rise or fall along the inclined surface 13, improving the smoothness of the movement of the push rod 9.

[0043] See also Figure 1 In this embodiment, the support surface 12 has a hemispherical recessed portion 15, the diameter of the recessed portion 15 is larger than the diameter of the contact portion 14, and when the gear 4 to be processed is transferred to the processing position, the contact portion 14 is located in the recessed portion 15 and abuts against the bottom of the recessed portion 15. The hemispherical shape of the recessed portion 15 provides a better positioning effect for the ejector 9. When the contact portion 14 is engaged in the recessed portion 15, the gear 4 to be processed is just located at the processing position, thereby achieving a good positioning function. In addition, since the diameter of the recessed portion 15 is larger than the diameter of the contact portion 14, the contact between the contact portion and the recessed portion is point contact.

[0044] See also Figure 3In this embodiment, the outer wall of the limiting portion 5 is provided with a protrusion 16 matching the keyway of the gear 4 to be processed. The protrusion 16 is located in the keyway of the gear 4 to be processed and is used to limit the rotation of the gear 4 to be processed. When the gear 4 to be processed is placed on the limiting portion 5, the protrusion 16 is just located in the keyway of the gear 4 to be processed. The protrusion 16 limits the rotation of the gear 4 to be processed, making it difficult for the gear 4 to be processed to rotate relative to the limiting portion 5, thereby further improving the fixing effect.

[0045] See also Figure 3 In this embodiment, the pressing part 8 is made of rubber. The elasticity of rubber means that the pressing part 8 can deform to a certain extent when subjected to pressure, thereby absorbing and dispersing the stress generated during the clamping process, so that the gear 4 to be processed is not damaged.

[0046] The second of the present invention: See also Figure 1-2 A deburring device includes a bracket 1, a clamping tool and a tooth groove cleaning component. The bracket 1 is a supporting structure of the entire device, fixed on the ground, and provides an installation foundation for other components.

[0047] The lifting portion 34 is fixed to the bracket 1, the turntable 3 is rotatably connected to the bracket 1, the placing platform 2 is a round rod-shaped structure, the placing platform 2 and the top rod 9 are in the same length direction, and both are vertically arranged. The placing platform 2 is rotatably connected to the turntable 3, allowing the placing platform 2 to rotate relative to the turntable 3 when driven by an external force.

[0048] The tooth groove cleaning component includes a brush wheel 17 and a first driving member 18. The brush wheel 17 is used to remove burrs in the tooth groove of the gear 4 to be processed. The brush wheel 17 is made of soft material to ensure that the gear surface will not be damaged during the cleaning process. The first driving member 18 is installed on the bracket 1. The output shaft of the first driving member 18 is connected to the axis of the brush wheel 17. When the top rod 9 contacts the recessed portion 15 of the top portion 34 (that is, when the gear 4 to be processed is in the position to be processed), the brush wheel 17 contacts the gear 4 to be processed. The brush wheel 17 is driven to rotate by the first driving member 18. During the rotation process, the brush wheel 17 cleans the tooth groove of the gear 4 to be processed and removes the burrs in the tooth groove of the gear 4 to be processed. The first driving member 18 can be a motor or other mechanical parts that can drive an object to rotate.

[0049] A first transmission assembly is provided between the first driving member 18 and the placing table 2. When the top rod 9 contacts the recessed portion 15 of the jacking portion 34, the first driving member 18 can drive the placing table 2 to rotate through the first transmission assembly, thereby driving the gear 4 to be processed to rotate. At the same time, the first driving member 18 will also rotate the synchronous brush wheel 17, and since the gear 4 to be processed is rotating, the brush wheel 17 can achieve comprehensive cleaning of the tooth grooves of the gear 4 to be processed. It should be noted that when the top rod 9 does not contact the recessed portion 15 of the jacking portion 34, the first transmission assembly does not work, that is, the first driving member 18 cannot drive the placing table 2 to rotate, and the gear 4 to be processed does not rotate.

[0050] When in use, place the gear 4 to be processed on the placement table 2 and ensure that it is stable and motionless. Rotate the turntable 3, the push rod 9 starts to move and contacts the recessed portion 15 of the lifting portion 34, and fixes the gear 4 to be processed to the position in contact with the brush wheel 17 (the push rod 9 contacts the recessed portion 15 of the lifting portion 34). At the same time, through the transmission action of the first transmission assembly, the first driving member 18 starts to drive the placement table 2 to rotate, thereby driving the gear 4 to be processed to rotate. The brush wheel 17 rotates under the action of the first driving member 18, contacts the tooth groove of the rotating gear 4 to be processed, and removes the burrs therein. After cleaning, continue to rotate the turntable 3, the push rod 9 descends, the gear 4 to be processed is released, and the gear 4 to be processed can be removed.

[0051] See also Figure 1-2Specifically, the first transmission component includes a first gear 19, a second gear 20, a worm wheel 21, a worm 22 and a transmission wheel assembly 23. The first gear 19 is fixedly sleeved on the outside of the placement table 2, the second gear 20 is rotatably mounted on the bracket 1, the first gear 19 and the second gear 20 are meshed, the worm wheel 21 is rotatably mounted on the bracket 1, the worm wheel 21 is coaxially connected with the second gear 20 through a connecting shaft, the worm 22 is rotatably mounted on the bracket 1 and is transmission-connected with the worm wheel 21, and the transmission wheel assembly 23 includes a first transmission wheel, a second transmission wheel and a third transmission wheel. The first transmission wheel is mounted on the output shaft of the drive, the second transmission wheel is rotatably mounted on the bracket 1, the first transmission wheel and the second transmission wheel are transmission-connected through the first transmission member, the third transmission wheel is rotatably mounted on the bracket 1, the third transmission wheel is coaxially connected with the worm 22, and the third transmission wheel and the second transmission wheel are transmission-connected through the second transmission member. More specifically, the transmission connection mode of the first transmission wheel and the second transmission wheel can be a sprocket type or a belt type, and the transmission connection mode of the second transmission wheel and the third transmission wheel can also be a sprocket type or a belt type. The first driving member drives the first transmission wheel to rotate, the first transmission wheel drives the second transmission wheel to rotate through the first transmission member, the second transmission wheel drives the third transmission wheel to rotate through the second transmission member, the third transmission wheel drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the second gear to rotate through the connecting shaft, the second gear drives the first gear to rotate, the first gear drives the placement table to rotate, and the placement table drives the gear to be processed to rotate.

[0052] In this embodiment: the deburring device also includes a controller and a sensor. The controller is connected to the sensor and the first driving member 18 by signals. The sensor is arranged in the recessed portion 15 and is used to detect the position of the push rod 9. When the push rod 9 moves into the recessed portion 15, the sensor can sense this change and send a signal. The specific sensor can be a pressure sensor. The push rod 9 will apply pressure to the recessed portion 15 under the action of the first spring 11, and the pressure sensor can sense this pressure change. The pressure sensor can be a pressure sensor of model DYHW-116.

[0053] When the push rod 9 moves into the recessed portion 15, the sensor detects this change and transmits a signal to the controller. After receiving the signal, the controller controls the first driving member 18 to start according to the preset program logic, thereby driving the brush wheel 17 to rotate and start removing the burrs of the gear 4 to be processed. When the push rod 9 moves out of the recessed portion 15, the sensor detects this change again and transmits a signal to the controller. After receiving the signal, the controller controls the first driving member 18 to stop working, thereby ending the burr removal work.

[0054] See also Figure 1-2In this embodiment: the deburring device also includes a tooth surface cleaning component, which includes a cleaning tool 24 and a second driving member 25. The cleaning tool 24 has two cleaning blades 26, which are respectively against the upper and lower side surfaces of the gear to be processed. The material of the cleaning blades 26 is usually selected from a material with moderate hardness and good wear resistance to ensure that the gear surface will not be damaged during the cleaning process. The second driving member 25 is used to drive the cleaning tool 24 away from or close to the gear 4 to be processed so that the two cleaning blades 26 are in contact with or disengaged from the upper and lower side surfaces of the gear to be processed. When the second driving member 25 drives the cleaning tool 24 to approach the gear 4 to be processed, the two cleaning blades 26 are in close contact with the upper and lower side surfaces of the gear, and the cleaning work begins. When the cleaning is completed, the second driving member 25 drives the cleaning tool 24 away from the gear so that the next cleaning can be carried out or the processed gear can be removed.

[0055] A second transmission assembly is arranged between the second driving member 25 and the turntable 3. The second transmission assembly only allows the second driving member to drive the turntable 3 to rotate when driving the cleaning tool 24 away from the gear 4 to be processed, thereby realizing intermittent unidirectional rotation of the turntable 3 during the process of the second driving member 25 periodically driving the cleaning tool 24 to move.

[0056] When in use, the gear 4 to be processed is placed on the placement table 2, and the second driving component is started. The second driving component drives the cleaning tool 24 to move away from the gear 4 to be processed. Under the transmission action of the second transmission component, the second driving component 25 drives the turntable 3 to rotate so that the gear 4 to be processed rotates to the position to be processed. In this process, the fixed block 7 will complete the fixing work of the gear 4 to be processed. The tooth groove cleaning component then completes the cleaning work of the gear 4 to be processed. Next, the second driving component 25 drives the cleaning tool 24 to approach the gear 4 to be processed, and the two cleaning blades 26 are in close contact with the upper and lower sides of the gear 4 to be processed. In this process, the second driving component 25 does not drive the turntable 3 to rotate. Therefore, in the process of driving the cleaning tool 24 to approach the gear 4 to be processed, the two cleaning blades 26 can respectively contact the upper and lower cleaning surfaces of the gear 4 to be processed. At the same time, since the gear 4 to be processed is continuously rotated with the placement table 2, the two cleaning blades 26 can clean the upper and lower surfaces of the gear 4 to be processed during the rotation process to scrape off the burrs on the upper and lower surfaces of the gear 4 to be processed. After cleaning is completed, the second driving member 25 drives the cleaning tool 24 away from the gear, and the second transmission assembly drives the turntable 3 to rotate, rotating the cleaned gear to the next position for subsequent removal. Such a cycle can achieve continuous cleaning of the burrs of the gear 4 to be processed.

[0057] Specifically, the second driving member 25 is a mechanical component such as a hydraulic push rod, an electric push rod, etc., which can push the cleaning tool 24 to perform linear motion.

[0058] See also Figure 1-2 The second transmission assembly includes a rack 27, a third gear 28, a fourth gear 29 and a one-way transmission member. The rack 27 is fixedly connected to the cleaning tool 24. The cleaning tool 24 can drive the rack 27 to move linearly synchronously when it moves linearly. The third gear 28 is meshed with the rack 27. The third gear 28 is rotatably mounted on the bracket 1 through the mounting shaft 30 (that is, the mounting shaft 30 is fixed on the mounting bracket 1, and the third gear 28 is sleeved on the mounting shaft 30). The rack 27 can drive the third gear 28 to rotate when it moves linearly. The fourth gear 29 and the third gear 28 are overlapped in the vertical direction, and The one-way transmission member is also rotatably mounted on the bracket 1 through the mounting shaft 30 (the fourth gear 29 is sleeved on the mounting shaft 30), and the one-way transmission member is arranged between the third gear 28 and the fourth gear 29. The one-way transmission member includes a first sleeve 31 and a second sleeve 32, both of which are sleeved on the mounting shaft 30, the first sleeve 31 is coaxially fixedly connected with the third gear 28, and the second sleeve 32 is coaxially fixedly connected with the fourth gear 29. The first sleeve 31 and the second sleeve are respectively provided with mutually meshing first and second locking teeth on opposite sides of the first sleeve and the second sleeve, and the first and second locking teeth are both inclined. It should be noted that the inclination direction of the first and second locking teeth is adapted to the driving direction of the second driving member 25 (that is, the one-way transmission member takes effect only when the second driving member drives the cleaning tool 24 to move away from the gear 4 to be processed). A second spring 33 is also provided on the top of the first sleeve 31. The second spring 33 is sleeved outside the mounting shaft 30. A limit plate is provided on the top of the mounting shaft 30. The upper end of the second spring 33 abuts against the limit plate, and the lower end is fixedly connected to the third gear 28. The turntable 3 is a gear ring structure and is meshed with the fourth gear 29.

[0059] When the second driving member 25 drives the cleaning tool 24 to move away from the gear 4 to be processed, the one-way transmission member will function (the first locking tooth and the second locking tooth are locked with each other and will not be disengaged under the elastic force of the second spring 33, and the first sleeve 31 can drive the second sleeve 32 to rotate synchronously). The specific transmission process is: the rack 27 moves synchronously away from the gear 4 to be processed, the rack 27 drives the third gear 28 to rotate, the third gear 28 drives the first sleeve 31 to rotate, the first sleeve 31 drives the second sleeve 32 to rotate under the action of the first locking tooth and the second locking tooth, the second sleeve 32 drives the fourth gear 29 to rotate, and the fourth gear 29 drives the turntable 3 to rotate. When the second driving member 25 drives the cleaning tool 24 to move toward the gear 4 to be processed, the one-way transmission member will not function (the first locking tooth and the second locking tooth are disengaged along the inclined locking surface, the first sleeve 31 cannot drive the second sleeve 32 to rotate synchronously, and the first locking tooth and the second locking tooth can always maintain a contact state under the elastic force of the second spring). The specific transmission process is: the rack 27 moves synchronously away from the gear 4 to be processed, the rack 27 drives the third gear 28 to rotate, the rotation of the third gear 28 drives the first sleeve 31 to rotate, the first sleeve 31 does not drive the second sleeve 32 to rotate, and then the fourth gear 29 rotates, and finally the turntable 3 does not rotate.
