Description

Technical Field

[0001] This invention belongs to the field of copper rod processing technology, and in particular relates to a copper rod grinding and polishing device. Background Technology

[0002] With the rapid development of the metal processing industry, copper rods, as important conductive and structural materials, have their surface grinding and polishing quality directly affecting the accuracy of subsequent processing and their performance. Traditional copper rod grinding and polishing equipment mostly relies on manual assistance or step-by-step mechanized operations, which has the following drawbacks: First, the application of polishing slurry relies on manual labor or simple spraying, making it difficult to achieve uniform coverage. This can easily lead to over-polishing or under-polishing in certain areas, and also results in significant waste of polishing slurry. Second, the dust and debris generated during the polishing process spread unorganized, requiring additional independent dust removal equipment. This not only takes up space but may also affect processing accuracy and the operating environment due to floating dust. Third, existing devices often use multiple motors to drive functional modules such as polishing, slurry application, and dust removal, resulting in complex equipment structures, high energy consumption, and difficulty in control.

[0003] To address these issues, we provide a copper rod grinding and polishing device. Summary of the Invention

[0004] The purpose of this invention is to provide a copper rod grinding and polishing device, which solves the problems of high energy consumption, uneven coating, and dust pollution in existing copper rod grinding and polishing devices by combining a coating mechanism and a dust removal mechanism.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0006] This invention relates to a copper rod grinding and polishing device, comprising a clamping mechanism, an axial drive frame fixedly connected to the top of the clamping mechanism, a hydraulic telescopic cylinder fixedly connected to the bottom of the axial drive frame, a fixed frame fixedly connected to the output end of the hydraulic telescopic cylinder, and a power shaft rotatably connected to the inner side of the fixed frame via a bearing seat; a coating mechanism is provided on one side of the fixed frame, the coating mechanism comprising a fixed plate fixedly connected to the bottom of the fixed frame, a fixed ring fixedly connected to one side of the fixed plate, and a coating ring slidably connected to the inner side of the fixed ring; a dust removal mechanism is provided on the other side of the fixed plate, the dust removal mechanism comprising a fan fixedly connected to one side of the fixed plate, a dust removal box connected to the air inlet of the fan via a pipe, and a dust suction chamber connected to one side of the dust removal box via a pipe.

[0007] The present invention is further configured such that a drive motor is fixedly connected to one side of the fixed frame, the output shaft of the drive motor is connected to the surface of the power shaft via a synchronous belt, a grinding wheel is fixedly connected to the surface of the power shaft, and the drive motor drives the power shaft and the grinding wheel to rotate at high speed via the synchronous belt for rough or fine grinding.

[0008] The invention is further configured such that a worm is fixedly connected to one end of the power shaft, a worm wheel meshes with the surface of the worm, a rotating shaft is fixedly connected to the center of the worm wheel, a cam is fixedly connected to the surface of the rotating shaft, and the rotating shaft is rotatably connected to one side of the fixed plate through a bearing seat and a mounting block. The worm at the end of the power shaft drives the worm wheel and the rotating shaft to rotate. The worm and the worm wheel constitute a speed reduction and torque amplification mechanism, converting the high-speed rotation of the power shaft into low-speed, high-torque rotation of the rotating shaft.

[0009] The present invention is further configured such that a first bevel gear is fixedly connected to both ends of the rotating shaft, a second bevel gear meshes with the surface of the first bevel gear, a transmission shaft is fixedly connected to the shaft center of the second bevel gear, a first gear is connected to the surface of the transmission shaft via a synchronous belt, and the two ends of the rotating shaft transmit power to the two transmission shafts on both sides via the first bevel gear and the second bevel gear, and then drive the symmetrically arranged first gears via the synchronous belt, and the first gear meshes with the rack on the outer edge of the coating ring.

[0010] The invention is further configured such that a polishing liquid tank is fixedly connected to one side of the fixed plate, a slide rod is fixedly connected to one side of the polishing liquid tank, a push plate is slidably connected to the surface of the slide rod, a spring is sleeved on the surface of the slide rod, and a squeezing block is fixedly connected to one side of the push plate. A cam on the rotating shaft periodically pushes the squeezing block as it rotates, causing the push plate to slide back and forth along the slide rod and compress the spring, thereby achieving intermittent squeezing of the side wall of the polishing liquid tank and triggering its built-in spray valve to spray polishing liquid onto the sponge block in a metered manner. A baffle is fixedly connected to one side of the slide rod, one side of the spring is fixedly connected to one side of the baffle, and the other end of the spring is fixedly connected to one side of the push plate. The spring provides a restoring force for the push plate to reset. A filling port is provided at the top of the polishing liquid tank, and a scale through window is provided on one side of the polishing liquid tank for convenient and timely addition of polishing liquid.

[0011] The invention is further configured such that the fixing ring is a 180-degree semi-ring, the coating ring is a fan-shaped ring with an angle greater than 180 degrees, a slider is fixedly connected to one side of the coating ring, a groove adapted to the slider is opened on the inner side of the fixing ring, a rack is fixedly connected to the surface of the coating ring, and a sponge block is fixedly connected to the inner side of the coating ring. Since the coating ring is a fan-shaped ring with an angle greater than 180 degrees and has two first gears driving it alternately, the two first gears mesh alternately with the rack of the fan-shaped coating ring. During the rotation, one first gear always provides driving force, ensuring that it drives the sponge block to rotate continuously and stably around the copper rod under the guidance of the groove of the fixing ring (the groove and the slider limit the coating ring, making its rotation more stable), and uniformly apply polishing liquid.

[0012] The invention is further configured such that a second gear is fixedly connected to the surface of the power shaft, a third gear meshes with the surface of the second gear, the shaft of the third gear is fixedly connected to the input shaft of the fan, and the diameter of the second gear is larger than that of the third gear, forming a speed-increasing gear pair, which converts the low-speed rotation of the coating ring into the high-speed rotation required by the input shaft of the fan, directly driving the fan to work.

[0013] The invention is further configured such that a filter screen is fixedly connected to the inner cavity of the dust collector, the filter screen is inclined at a certain angle to the horizontal plane, and a collection box is provided in the inner cavity of the dust collector. The inclined filter screen guides dust and waste to slide into the collection box, which is convenient for centralized cleaning and avoids clogging of the air duct.

[0014] The invention is further configured such that the air outlet of the fan is connected to an exhaust pipe, the dust collection chamber is frame-shaped, and the frame-shaped dust collection chamber forms a negative pressure surrounding area to efficiently capture dust and splashing debris generated during grinding and polishing. The exhaust port of the exhaust pipe faces the surface of the drive motor to dissipate heat from the drive motor and to reuse the airflow.

[0015] The invention is further configured such that a control panel is provided on the front of the clamping mechanism, the control panel being used to centrally control the operating parameters of the drive motor, the hydraulic telescopic cylinder and the axial drive frame.

[0016] The present invention has the following beneficial effects.

[0017] 1. This invention uses a single drive motor to link the grinding wheel, coating mechanism, and dust removal fan. It utilizes a worm gear, bevel gear set, and speed-increasing gear to achieve power distribution, significantly reducing energy consumption while ensuring functional completeness. It avoids the complexity of multi-motor coordinated control. The cam extrusion mechanism, combined with the spring reset design, dynamically binds the spray trigger of the polishing liquid tank to the rotation speed of the grinding wheel, realizing on-demand quantitative spraying of polishing liquid. Combined with the continuous rotation of the sponge block on the surface of the copper rod (the coating ring angle is greater than 180 degrees and is driven alternately by double gears), it ensures uniform liquid film coverage, reducing the amount of polishing liquid used compared to traditional spraying methods.

[0018] 2. The dust removal mechanism of this invention has a frame-shaped dust suction chamber that surrounds the grinding area to form a negative pressure zone. Combined with an inclined filter screen (to facilitate dust sliding) and a pull-out collection box, it can achieve efficient dust collection and convenient cleaning. The fan is driven by a power shaft through a speed-increasing gear pair, which does not require an additional power source. The high-speed airflow is blown to the drive motor through the exhaust pipe, which also takes into account the heat dissipation function of the equipment.

[0019] 3. The present invention's fan obtains high negative pressure suction through gear speed increase (the diameter of the second gear is larger than that of the third gear), and the sliding groove limit design of the coating ring, the pull-out collection box of the dust collector, and the transparent scale window of the polishing liquid box improve the maintainability of the equipment.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1 Please see Figures 1-8 This invention relates to a copper rod polishing device, comprising a clamping mechanism 1, an axial drive frame 2 fixedly connected to the top of the clamping mechanism 1, a hydraulic telescopic cylinder 3 fixedly connected to the bottom of the axial drive frame 2, a fixed frame 4 fixedly connected to the output end of the hydraulic telescopic cylinder 3, and a power shaft 5 rotatably connected to the inner side of the fixed frame 4 via a bearing seat; a coating mechanism is provided on one side of the fixed frame 4, the coating mechanism comprising a fixed plate 6 fixedly connected to the bottom of the fixed frame 4, a fixed ring 7 fixedly connected to one side of the fixed plate 6, and a coating ring 8 slidably connected to the inner side of the fixed ring 7; a drive motor 12 fixedly connected to one side of the fixed frame 4, the output shaft of the drive motor 12 being connected to the surface of the power shaft 5 via a synchronous belt; a polishing wheel 13 fixedly connected to the surface of the power shaft 5; the fixed ring 7 being a 180-degree semi-ring; the coating ring 8 being a fan-shaped ring with an angle greater than 180 degrees; a slider 27 fixedly connected to one side of the coating ring 8; a groove 28 adapted to the slider 27 being opened on the inner side of the fixed ring 7; a rack 29 fixedly connected to the surface of the coating ring 8; and a sponge block 30 fixedly connected to the inner side of the coating ring 8.

[0033] Furthermore, the clamping mechanism 1 is used to fix the copper rod, the axial drive frame 2 drives the entire polishing unit to move along the axial direction of the copper rod, the hydraulic telescopic cylinder 3 controls the lifting and lowering of the fixing frame 4 and the components below, the drive motor 12 drives the power shaft 5 and the grinding wheel 13 to rotate at high speed via a synchronous belt for rough or fine grinding, and at the same time the worm gear 14 at the end of the power shaft 5 drives the worm wheel 15 and the rotating shaft 16 to rotate. The worm gear 14 and the worm wheel 15 form a speed reduction and torque amplification mechanism, which converts the high-speed rotation of the power shaft 5 into the low-speed, high-torque rotation of the rotating shaft 16. The two ends of the rotating shaft 16 transmit power to the two sides via the first bevel gear 18 and the second bevel gear 19. The moving shaft 20 drives the symmetrically arranged first gears 21 through a synchronous belt. The first gears 21 mesh with the rack 29 on the outer edge of the coating ring 8. Since the coating ring 8 is a sector shape greater than 180 degrees and has two first gears 21 driving it alternately, the two first gears 21 mesh with the rack 29 of the sector-shaped coating ring 8 alternately. During the rotation, there is always one first gear 21 providing driving force, ensuring that it drives the sponge block 30 to rotate continuously and stably around the copper rod under the guidance of the slide groove 28 of the fixed ring 7 (the slide groove 28 and the slider 27 limit the coating ring 8 to make its rotation more stable), and evenly apply polishing liquid.

[0034] Example 2 Please see Figures 1-8Based on Embodiment 1, a worm gear 14 is fixedly connected to one end of the power shaft 5. A worm wheel 15 meshes with the surface of the worm gear 14. A rotating shaft 16 is fixedly connected to the center of the worm wheel 15. A cam 17 is fixedly connected to the surface of the rotating shaft 16. The rotating shaft 16 is rotatably connected to one side of the fixed plate 6 through a bearing seat and a mounting block. A first bevel gear 18 is fixedly connected to both ends of the rotating shaft 16. A second bevel gear 19 meshes with the surface of the first bevel gear 18. A transmission shaft 20 is fixedly connected to the center of the second bevel gear 19. A first gear 21 is connected to the surface of the transmission shaft 20 through a synchronous belt. A polishing liquid tank 22 is fixedly connected to one side of the fixed plate 6. A slide rod 23 is fixedly connected to one side of the polishing liquid tank 22. A push plate 24 is slidably connected to the surface of the slide rod 23. A spring 25 is sleeved on the surface of the slide rod 23. A pressing block 26 is fixedly connected to one side of the push plate 24.

[0035] Furthermore, the cam 17 on the rotating shaft 16 periodically pushes the extrusion block 26 as it rotates. The cam 17 periodically pushes the extrusion block 26 as it rotates, causing the push plate 24 to slide back and forth along the slide rod 23 and compress the spring 25, thereby achieving intermittent extrusion on the side wall of the polishing liquid tank 22. This triggers the built-in spray valve to spray polishing liquid onto the sponge block 30 in a measured amount. A baffle is fixedly connected to one side of the slide rod 23, and one side of the spring 25 is fixedly connected to one side of the baffle. The other end of the spring 25 is fixedly connected to one side of the push plate 24. The spring 25 provides a restoring force for the push plate 24 to reset. The top of the polishing liquid tank 22 is provided with a filling port, and a scale through window is provided on one side of the polishing liquid tank 22 for convenient and timely addition of polishing liquid.

[0036] Example 3 Please see Figures 1-8 Based on Embodiments 1 and 2, a dust removal mechanism is provided on the other side of the fixed plate 6. The dust removal mechanism includes a fan 9 fixedly connected to one side of the fixed plate 6, a dust collection box 10 connected to the air inlet of the fan 9 through a pipe, a dust suction chamber 11 connected to one side of the dust collection box 10 through a pipe, a second gear 31 fixedly connected to the surface of the power shaft 5, a third gear 32 meshing with the surface of the second gear 31, and the shaft of the third gear 32 fixedly connected to the input shaft of the fan 9. A filter screen 33 is fixedly connected to the inner cavity of the dust collection box 10. The filter screen 33 is inclined at a certain angle to the horizontal plane. A collection box 34 is provided in the inner cavity of the dust collection box 10. An exhaust pipe 35 is connected to the air outlet of the fan 9. The dust suction chamber 11 is frame-shaped. A control panel 36 is provided on the front of the clamping mechanism 1.

[0037] Further supplement: The rotation of the power shaft 5 drives the second gear 31 on its surface to rotate. The second gear 31 meshes with the third gear 32 fixed on the input shaft of the fan 9. The diameter of the second gear 31 is larger than that of the third gear 32, forming a speed-increasing gear pair. This converts the low-speed rotation of the coating ring 8 into the high-speed rotation required by the input shaft of the fan 9, directly driving the fan 9 to work. The negative pressure generated by the fan 9 acts on the frame-type dust collection chamber 11 through the pipe. The dust collection chamber 11 surrounds the area of ​​the grinding wheel 13, forming a negative pressure zone. Grinding dust, polishing waste, and mist are efficiently sucked into the pipe and enter the dust collection box 10. The dust-laden airflow first hits the inclined filter screen 33. Dust and larger particles are intercepted and slide down the inclined surface into the pull-out collection box 34 at the bottom. The filtered gas is discharged from the exhaust pipe 35 through the fan 9. The exhaust port of the exhaust pipe 35 faces the surface of the drive motor 12 to dissipate heat from the drive motor 12 and reuse the airflow. The control panel 36 integrates and controls parameters such as the speed of the drive motor 12, the lifting of the hydraulic cylinder, and the axial feed speed. The working principle of this invention is as follows: the copper rod is fixedly installed by the clamping mechanism 1, the hydraulic telescopic cylinder 3 moves down, so that the grinding wheel 13, the coating ring 8 (the bottom of the coating ring 8 is an open structure, which can be directly sleeved on the surface of the copper rod), and the dust suction chamber 11 surround the copper rod, the drive motor 12 starts, and drives the power shaft 5 and the grinding wheel 13 to rotate at high speed to grind the surface of the copper rod, and the axial drive frame 2 drives the entire unit to move at a uniform speed along the axial direction of the copper rod.

[0038] When the power shaft 5 rotates, the worm 14 at one end drives the worm wheel 15 to rotate. The worm wheel 15 drives the cam 17 to rotate through the rotating shaft 16. During the rotation of the cam 17, the push plate 24 is pushed to move back and forth along the slide bar 23. The push plate 24 intermittently squeezes the spraying mechanism at the bottom of the polishing liquid tank 22 through the extrusion block 26, so that the polishing liquid is evenly sprayed onto the sponge block 30. At the same time, the first bevel gear 18 at both ends of the rotating shaft 16 drives the second bevel gear 19 to rotate. The second bevel gear 19 drives the first gear 21 to rotate through the transmission shaft 20. Since the coating ring 8 is a fan-shaped ring (angle greater than 180 degrees) and is slidably connected to the groove 28 of the fixed ring 7 through the slider 27, the first gear 21 always meshes with the rack 29 of the coating ring 8, driving the coating ring 8 to rotate around the fixed ring 7. The sponge block 30 rotates with the coating ring 8 and evenly coats the copper rod surface with polishing liquid.

[0039] The power shaft 5 drives the fan 9 to rotate at high speed through the speed-increasing transmission of the second gear 31 and the third gear 32 (the diameter of the second gear 31 is larger than that of the third gear 32). The fan 9 creates a negative pressure in the copper rod grinding area through the dust suction chamber 11, sucking the dust and debris generated during grinding into the dust collection box 10. The dust and debris are filtered by the filter screen 33 (the filter screen 33 is set at an angle to facilitate the sliding of debris) and fall into the collection box 34 at the bottom. The purified air is discharged through the exhaust pipe 35 and blows the high-speed airflow towards the drive motor 12 to dissipate heat.

[0040] This invention uses a single drive motor 12 to achieve three functions: grinding, uniform application of polishing liquid, and efficient dust removal. It has a compact structure and reduces energy consumption. The cam 17 provides pressure-type liquid supply, which, together with the sponge block 30, rotates and applies the polishing liquid, achieving precise quantitative supply and uniform coverage, thus reducing the amount used.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
