[0002] The harmonic reducer is a special gear transmission device, which is mainly composed of three basic components: a wave generator, a flexible gear and a rigid gear. It uses the wave generator to make the flexible gear produce controllable elastic deformation, thereby achieving meshing with the rigid gear to transmit motion and power. The harmonic reducer has the characteristics of large transmission ratio, high precision, high efficiency and light weight, and is widely used in robotics, aerospace, navigation, machinery manufacturing and other fields.

[0006] The scroll cylinder is installed on the frame through a vertical plate, and the vertical plate is arranged on the frame. The interior of the scroll cylinder is hollow, and a plurality of input ports are arranged on one side of the scroll cylinder, and an output port is arranged on the other side of the scroll cylinder. A partition is arranged inside the scroll cylinder, and a scroll sheet is arranged between one side of the partition and the inner wall of the scroll cylinder, and a filter is arranged between the other side of the partition and the inner wall of the scroll cylinder. A dust removal space is arranged in the scroll sheet, and the scroll sheet and the dust removal space are both planar threaded structures. The dust removal space is connected with the plurality of input ports, and the partition is provided with a connecting port at a position corresponding to the center of the scroll sheet.

[0007] Two groups of scroll shafts are arranged in sequence in the dust removal space, and the two groups of scroll shafts are arranged on the partition plate and the scroll cylinder, and the cleaning plate is slidably installed on the two groups of scroll shafts, and the cleaning plate and one end of the scroll shaft are connected through a reset spring, and the reset spring is sleeved on the scroll shaft; The two sides of the cleaning plate are in sliding contact with the inner wall of the vortex sheet, brushes are arranged on the two sides of the cleaning plate, and the reset tension spring is electrically connected to the control system.

[0008] The gear ring is arranged on the inner wall of the protective cover, the sun gear is mounted on the output shaft of the driving motor, the plurality of sets of planetary gears are rotatably mounted on the planetary carrier through bearings, the planetary carrier is located above the plurality of sets of planetary gears, and the middle part of the planetary carrier is rotatably mounted on the output shaft of the driving motor through bearings; A plurality of protrusions are arranged on the outer side of the planet carrier, and there are intervals between the plurality of protrusions and the planetary gears.

[0009] A pressurized cover is arranged on the inner wall of the protective cover outside the planet carrier, and the pressurized cover is arranged in multiple groups. The liquid storage bag is located in the pressurized cover, and the liquid storage bag is provided with a coolant. The cross section of the reciprocating plate is I-shaped, one end of the reciprocating plate is located in the pressurized cover and abuts against the liquid storage bag, and the other end of the reciprocating plate passes through the pressurized cover and abuts against the protrusion on the planet carrier. The reciprocating plate is connected to the outer wall of the pressurized cover by a spring, and the reciprocating plate slides on the pressurized cover; Both ends of the liquid storage bag are arranged on the pressure cover, a filling port is arranged on the protective cover, and a plurality of spray ports are arranged on the lower side of the pressure cover. The plurality of spray ports are connected to the liquid storage bag through pipes, and the liquid storage bag is connected to the filling port through pipes. Solenoid valves and flow meters are installed in the pipes connected to the liquid storage bag, and the solenoid valves and flow meters are electrically connected to the control system.

[0010] The upper side of the protective cover is connected with a telescopic rod of a lifting electric cylinder, the lifting electric cylinder is installed on a bracket, and the upper side of the protective cover is provided with a guide shaft, and the guide shaft is slidably connected with the bracket.

[0011] Press the start button on the control panel to start the device, place the gear to be processed on the carrier plate, the lower side of the gear to be processed and the upper side of the carrier plate fit each other, the control system controls the clamping electric cylinder to drive the clamping plate to insert into the tooth shape of the gear to be processed, and the clamping plate positions and clamps the gear to be processed. Since multiple sets of clamping electric cylinders and clamping plates are provided, positioning and clamping of different positions of the gear to be processed can be achieved, thereby improving the clamping effect.

[0012] After the gear to be processed is positioned by multiple sets of clamping electric cylinders, the multiple sets of clamping electric cylinders feed back pressure signals to the control system. The control system controls the lifting electric cylinders to drive the protective cover to move downward, and the protective cover drives the drive motor, sun gear, planetary gear, ring gear and polishing plate to move downward, so that the polishing plate contacts the tooth surface of the gear to be processed.

[0013] When the polishing plate contacts the tooth surface of the gear to be processed, the displacement sensor in the lifting electric cylinder feeds back data to the control system. The control system controls the drive motor to drive the sun gear to rotate. With the cooperation of the ring gear, the sun gear drives the planetary gear to rotate and revolve. The planetary gear synchronously drives the planetary carrier to rotate. The protrusion on the planetary carrier follows the rotation, and the polishing plate on the lower side of the planetary gear follows the rotation. The polishing plate polishes the tooth surface of the gear to be processed.

[0014] When the driving motor drives the polishing plate to rotate, the control system opens the solenoid valve in the pipeline between the spray port and the liquid storage bag. The protrusion on the planetary carrier pushes the reciprocating plate to move into the pressurized cover and compresses the spring. The reciprocating plate squeezes the liquid storage bag in the pressurized cover, so that the coolant in the liquid storage bag is transported to the spray port through the pipeline. The coolant is sprayed onto the tooth surface of the gear to be processed through the spray port. The coolant cools the polishing plate and the gear to be processed, thereby extending the service life of the polishing plate.

[0015] While the polishing plate is polishing the gear to be processed, the control system controls the vacuum pump to work. The vacuum pump draws the air in the vortex cylinder outward through the pipe and the output port, so that the debris generated during polishing and the excess coolant enter the dust removal space through the input port. The high-temperature debris first contacts the temperature difference plate A in the dust removal space. After that, the debris and coolant flow along the dust removal space and enter the right side of the filter through the connecting port. The coolant passes through the filter and is extracted outward from the output port by the vacuum pump for further processing. The debris cannot pass through the filter and is deposited on the right side of the filter. The staff can remove the debris that has been deposited for a long time by removing the discharge plate.

[0016] After the vortex blade has been working for a long time, a certain amount of debris is deposited in the dust removal space, and the resistance of the vacuum pump to extraction becomes larger. The vacuum pump feeds back the pressure data to the control system. The control system controls the vacuum pump to stop working and energizes the reset spring. A mutually attractive magnetic field is generated between each turn of the reset spring. The magnetic field compresses the reset spring, shortening the reset spring as a whole. The reset spring pulls the cleaning plate to slide on the vortex shaft. The brushes on both sides of the cleaning plate clean the dust removal space and push the cleaned debris to the side close to the connecting port. After that, the control system controls the vacuum pump to work, and the vacuum pump extracts the debris in the connecting port and the dust removal space through the output port and the pipeline again.

[0017] A plurality of temperature difference plates A are arranged on the inner wall of the scroll sheet, and the plurality of temperature difference plates A are located in the dust removal space. A plurality of temperature difference plates B are arranged on the inner wall of the scroll cylinder near the outlet, and the plurality of temperature difference plates A correspond to the plurality of temperature difference plates B one by one. The temperature difference plate A, the temperature difference plate B and the refrigeration plate are all provided with semiconductors of two different materials and a metal plate, one end of the semiconductors of the two different materials are connected to the metal plate, the two semiconductors on the temperature difference plate A and the two semiconductors on the temperature difference plate B are connected by wires, one of which is connected to the control system, and the two semiconductors on the refrigeration plate are electrically connected to the control system through the wires. The two semiconductors and metal plate on the temperature difference plate A are the hot end of the Seebeck effect, the two semiconductors and metal plate on the temperature difference plate B are the cold end of the Seebeck effect, and the two semiconductors and metal plate on the cooling plate are the cooling end of the Peltier effect. The high-temperature debris generated after polishing enters the dust removal space through the input port, and the high-temperature debris contacts the temperature difference plate A in the dust removal space, and the temperature difference plate B is located on the inner wall of the vortex cylinder close to the output port, so the temperature of the hot end is higher than that of the cold end. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system uses the current for cooling the cooling end after rectification and voltage transformation. The cooling end cools the coolant through the Peltier effect. When the current generated by the hot end and the cold end through the Seebeck effect is low, the control system directly supplies power to the cooling end to ensure normal cooling of the coolant.

[0018] The input port is close to the carrier plate, the output port is connected to a vacuum pump through a pipeline, and the vacuum pump is installed on the frame.

[0019] The carrier plate is rotatably mounted on a support frame, the support frame is arranged on a frame, a rotating motor is mounted below the support frame, the output shaft of the rotating motor passes through the support frame and is connected to the carrier plate, the rotating motor is mounted on the frame, the upper side of the carrier plate is adapted to the surface of the gear to be processed; when the position of the gear to be processed needs to be adjusted, the staff controls the rotating motor to drive the carrier plate to rotate through the control system, and the carrier plate drives the gear to be processed to rotate to the desired angle for further polishing.

[0020] The clamping assembly includes a clamping electric cylinder and a clamping plate. The clamping electric cylinder is provided in multiple groups. The multiple groups of clamping electric cylinders are installed on a support frame. The clamping plate is installed on a telescopic rod of the clamping electric cylinder. The multiple groups of clamping electric cylinders and clamping plates are distributed along the outer side of the carrier plate. The clamping plate is adapted to the tooth shape of the gear to be processed.

[0021] A discharge plate is arranged on the scroll cylinder between the filter screen and the partition plate, and the discharge plate and the scroll cylinder are detachably connected. A control panel is arranged on the frame, and the control system is arranged in the control panel.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. Automatically spray coolant to cool down during polishing, extending the service life of the polishing plate. When the drive motor drives the polishing plate to rotate, the control system opens the solenoid valve in the pipeline between the spray port and the liquid storage bag. The protrusion on the planetary carrier pushes the reciprocating plate to move into the pressurized cover and compresses the spring. The reciprocating plate squeezes the liquid storage bag in the pressurized cover, so that the coolant in the liquid storage bag is transported to the spray port through the pipeline. The coolant is sprayed on the tooth surface of the gear to be processed through the spray port. The coolant cools the polishing plate and the gear to be processed, extending the service life of the polishing plate.

[0023] 2. Debris adsorption treatment to avoid personal injury caused by debris. The vacuum pump draws the air in the vortex cylinder outward through the pipeline and the output port, so that the debris generated during polishing and the excess coolant enter the dust removal space through the input port. The high-temperature debris first contacts the temperature difference plate A in the dust removal space, and the debris and coolant flow along the dust removal space and enter the right side of the filter through the connecting port. The coolant passes through the filter and is extracted outward from the output port by the vacuum pump for further treatment, while the debris cannot pass through the filter. The debris is deposited on the right side of the filter. The staff can remove the long-deposited debris by removing the discharge plate to avoid personal injury caused by the debris.

[0024] 3. Recycle the energy of high-temperature debris to reduce the energy consumption of polishing equipment. The high-temperature debris generated after polishing enters the dust removal space through the input port. The high-temperature debris contacts the temperature difference plate A in the dust removal space, and the temperature difference plate B is located on the inner wall of the vortex cylinder near the output port. Therefore, the temperature of the hot end is higher than that of the cold end. The hot and cold ends generate current through the Seebeck effect and transmit it to the control system. The control system processes the current through rectification and voltage conversion, and then uses it to cool the cooling end. The cooling end uses the Peltier effect to cool the coolant to achieve energy recycling and reduce the energy consumption of polishing equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The carrier plate 3 is rotatably mounted on a support frame 112, and the support frame 112 is arranged on the frame 11.

[0034] Working principle: Press the start button on the control panel 1, the device starts, and the gear to be processed is placed on the carrier plate 3. The lower side of the gear to be processed and the upper side of the carrier plate 3 fit each other. The control system controls the clamping electric cylinder 15 to drive the clamping plate 151 to insert into the tooth shape of the gear to be processed. The clamping plate 151 positions and clamps the gear to be processed. Since multiple groups of clamping electric cylinders 15 and clamping plates 151 are provided, the positioning and clamping of different positions of the gear to be processed can be achieved, thereby improving the clamping effect.

[0035] After the gear to be processed is positioned by multiple sets of clamping electric cylinders 15, the multiple sets of clamping electric cylinders 15 feed back pressure signals to the control system. The control system controls the lifting electric cylinders 13 to drive the protective cover 12 to move downward. The protective cover 12 drives the drive motor 2, the sun gear 21, the planetary gear 22, the ring gear 23 and the polishing plate 27 to move downward, so that the polishing plate 27 contacts the tooth surface of the gear to be processed.

[0036] When the polishing plate 27 contacts the tooth surface of the gear to be processed, the displacement sensor in the lifting cylinder 13 feeds back data to the control system, and the control system controls the drive motor 2 to drive the sun gear 21 to rotate. With the cooperation of the ring gear 23, the sun gear 21 drives the planetary gear 22 to rotate and revolve, and the planetary gear 22 synchronously drives the planetary carrier 24 to rotate. The protrusion on the planetary carrier 24 rotates accordingly, and the polishing plate 27 on the lower side of the planetary gear 22 rotates accordingly, and the polishing plate 27 polishes the tooth surface of the gear to be processed.

[0037] When the driving motor 2 drives the polishing plate 27 to rotate, the control system opens the solenoid valve in the pipeline between the spray port 122 and the liquid storage bag 26, and the protrusion on the planetary carrier 24 pushes the reciprocating plate 25 to move into the pressurizing cover 121 and compresses the spring. The reciprocating plate 25 squeezes the liquid storage bag 26 in the pressurizing cover 121, so that the coolant in the liquid storage bag 26 is transported to the spray port 122 through the pipeline. The coolant is sprayed onto the tooth surface of the gear to be processed through the spray port 122. The coolant cools the polishing plate 27 and the gear to be processed, thereby extending the service life of the polishing plate 27.

[0038] While the polishing plate 27 is polishing the gear to be processed, the control system controls the vacuum pump to work. The vacuum pump draws the air in the vortex cylinder 4 outward through the pipeline and the output port 402, so that the debris generated during polishing and the excess coolant enter the dust removal space 441 through the input port 401. The high-temperature debris first contacts the temperature difference plate A42 in the dust removal space 441. Then, the debris and the coolant flow along the dust removal space 441 and enter the right side of the filter screen 45 through the connecting port 404. The coolant passes through the filter screen 45 and is extracted outward from the output port 402 by the vacuum pump for further processing. The debris cannot pass through the filter screen 45 and is deposited on the right side of the filter screen 45. The staff can remove the debris that has been deposited for a long time by removing the discharge plate.

[0039] After the vortex blade 44 has been working for a long time, a certain amount of debris is deposited in the dust removal space 441, and the resistance of the vacuum pump to extraction becomes larger. The vacuum pump feeds back the pressure data to the control system. The control system controls the vacuum pump to stop working and energizes the reset spring 46. A mutually attractive magnetic field is generated between each turn of the reset spring 46. The magnetic field compresses the reset spring 46, causing the reset spring 46 to shorten as a whole. The reset spring 46 pulls the cleaning plate 41 to slide on the vortex shaft 47. The brushes on both sides of the cleaning plate 41 clean the dust removal space 441 and push the cleaned debris to the side close to the connecting port 404.
