Description

Technical Field

[0001] This application relates to the field of polishing fixture technology, and in particular to a robotic polishing fixture. Background Technology

[0002] With the rapid development of industrial automation, robotics is increasingly widely used in manufacturing, especially in precision machining and surface treatment. Polishing, as a key process in product surface treatment, has a significant impact on product quality and appearance. Traditional polishing processes rely on manual operation, which is not only inefficient but also difficult to guarantee consistency. Therefore, robotic polishing fixtures have emerged as important tools for improving polishing efficiency and quality. The Pegasus lower housing, as a common industrial component, has high surface polishing requirements and a complex shape. Traditional clamping methods are insufficient to meet its polishing needs, necessitating a high-efficiency and stable robotic polishing fixture.

[0003] Currently, robotic polishing fixtures primarily employ a gripper-within-the-grab method to hold and polish workpieces. This design applies support force from within the workpiece through the gripper, fixing the workpiece to the fixture for polishing. The gripper-within-the-grab method is suitable for workpieces with stable internal structures and provides good gripping force.

[0004] Existing robotic polishing fixtures typically use grippers with internal bracing to hold and polish the lower shell of the Pegasus. However, the outer side of the Pegasus lower shell lacks resistance, making it difficult to provide sufficient gripping stability relying solely on internal bracing. During polishing, the lack of effective support on the outer side of the workpiece makes it susceptible to loosening or even detachment due to the polishing force. This not only affects polishing quality but may also lead to equipment damage or production interruption. Utility Model Content

[0005] The purpose of this application is to address the problem that relying solely on the internal support of the grippers is insufficient to provide adequate gripping stability, and that during the polishing process, the workpiece is prone to loosening or even detachment due to the lack of effective fixed support on the outer side, which is easily affected by the polishing force. This application provides a robotic polishing fixture.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A robotic polishing fixture includes a processing table, one end of which is rotatably connected to a contact wheel and another end of which is rotatably connected to a traction wheel. A polishing belt is sleeved around the contact wheel and the traction wheel. A robotic arm is fixedly connected to one end of the processing table, and a mounting platform is fixedly connected to the end of the robotic arm. A rotary processing slide is symmetrically rotatably connected to one end of the mounting platform. An inner support plate is symmetrically slidably connected to one end of the rotary processing slide, and an outer clamping plate is symmetrically hinged to one end of the rotary processing slide. A cylinder is symmetrically hinged to one end of the rotary processing slide, and the output end of the cylinder is hinged to one end of the outer clamping plate. A drive assembly is mounted on one end of the processing table.

[0008] By adopting the above technical solution, and by setting up the driving component to work in conjunction with the cylinder and the outer clamping plate, it is convenient to start the rotary machining slide to drive the two inner support plates to move away from each other and form an inner support contact with the inner wall of the workpiece. At the same time, the cylinder is started to drive the outer clamping plate to work with the inner support plate to clamp and fix one end of the workpiece. Then, the robot arm and the driving component are started, so that the robot arm drives the workpiece to move towards the polishing belt that is circulating around the outer periphery of the contact wheel and the traction wheel, and polishes the surface of the workpiece through the polishing belt. This effectively improves the clamping stability of the device on the workpiece and reduces the possibility of the workpiece loosening and falling off.

[0009] Furthermore, the inner support plate is symmetrically provided with adaptive sliding grooves, and T-shaped sliding rods are slidably connected inside the adaptive sliding grooves. One end of each of the two T-shaped sliding rods passes through the inner support plate and is fixedly connected to an abutment head. One end of each T-shaped sliding rod is fixedly connected to an abutment spring, and the abutment spring is installed inside the adaptive sliding groove.

[0010] By adopting the above technical solution, and by setting the T-shaped slide bar in conjunction with the contact head and the contact spring, it is convenient to make the contact head contact the bottom of the workpiece when the drive inner support plate is inserted into the workpiece, and push the T-shaped slide bar to compress the contact spring to produce a contraction deformation, so that the contact head can achieve the best matching state each time it is inserted into the workpiece and ensure good contact stiffness to avoid deformation.

[0011] Furthermore, an adjustment groove is provided at one end of the outer clamping plate, and a T-shaped adjustment clamping plate is slidably connected inside the adjustment groove. An adjustment screw that is threadedly connected to the T-shaped adjustment clamping plate is rotatably connected inside the adjustment groove. An adjustment motor is fixedly connected inside the outer clamping plate, and the output end of the adjustment motor is threadedly connected to the T-shaped adjustment clamping plate.

[0012] By adopting the above technical solution, and by setting the adjustment screw and the T-shaped adjustment clamp to work together, the starting adjustment motor drives the adjustment screw to form a threaded connection with the T-shaped adjustment clamp, thereby allowing the T-shaped adjustment clamp to move along the length of the adjustment groove to a length that matches the workpiece, thus improving the applicability of the device.

[0013] Furthermore, a rubber pad is fixedly connected to one end of both the contact head and the T-shaped adjusting clamp.

[0014] By adopting the above technical solution, and by setting up the rubber pad in conjunction with the contact head and the T-shaped adjusting clamp, the wear between the workpiece and the contact head and the T-shaped adjusting clamp is effectively reduced, thus extending the service life of the device.

[0015] Furthermore, the drive assembly includes a drive wheel fixedly connected to one end of the processing table, one end of the polishing belt wraps around the periphery of the drive wheel, one end of the drive wheel passes through the processing table and is fixedly connected to a worm gear, a polishing motor is fixedly connected to the outside of the processing table, and a worm gear meshing with the worm gear is fixedly connected to the output end of the polishing motor.

[0016] By adopting the above technical solution, and by setting up the cooperation between the worm gear and the worm, the starting polishing motor can drive the worm and the worm gear to mesh, and the worm gear can drive the driving wheel to rotate. At the same time, the driving wheel, in conjunction with the polishing belt, drives the contact wheel and the traction wheel to rotate synchronously, so that the polishing belt circulates around the contact wheel, the traction wheel, and the driving wheel.

[0017] Furthermore, a fine grinding wheel is rotatably connected to one end of the processing table, and a transmission assembly is installed at one end of the drive wheel.

[0018] By adopting the above technical solution and setting the transmission component and the fine grinding wheel to work together, it is convenient to drive the fine grinding wheel to rotate when the polishing belt is used to polish the surface of the workpiece, so as to achieve fine grinding of the surface of the workpiece and improve the polishing accuracy of the device.

[0019] Furthermore, the transmission assembly includes a transmission gear one fixedly connected to one end of the drive wheel, and one end of the fine grinding wheel passes through the processing table and is fixedly connected to a transmission gear two that meshes with the transmission gear one.

[0020] By adopting the above technical solution and setting the transmission gear one and transmission gear two to work together, it is convenient to drive the transmission gear one and transmission gear two to mesh when the polishing motor is driven to rotate, so that the transmission gear two drives the fine grinding wheel to rotate, thereby improving the practicality of the device.

[0021] Furthermore, a water storage tank is provided inside the processing table, and a water pump is fixedly connected to the output end of the water storage tank, and a self-shaping spray pipe is fixedly connected to the output end of the water pump.

[0022] By adopting the above technical solution and using a water pump in conjunction with a self-aligning nozzle, it is easy to spray the coolant inside the water storage tank onto the workpiece surface through the self-aligning nozzle by starting the water pump, thereby facilitating rapid cooling of the workpiece surface and improving the practicality of the device.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By setting up the drive assembly in conjunction with the cylinder and outer clamping plate, it is easy to start the rotary machining slide to drive the two inner support plates to move away from each other and form an inner support contact with the inner wall of the workpiece. At the same time, the cylinder drives the outer clamping plate to cooperate with the inner support plate to clamp and fix one end of the workpiece. Then, the robot arm and drive assembly are started, so that the robot arm drives the workpiece to move towards the polishing belt that circulates around the outer periphery of the contact wheel and the traction wheel. The polishing belt polishes the surface of the workpiece, thereby effectively improving the clamping stability of the device and reducing the possibility of the workpiece loosening and falling off.

[0025] 2. By setting up a T-shaped slide bar in conjunction with the contact head and contact spring, it is easy to make the contact head contact the bottom of the workpiece when the drive inner support plate is inserted into the workpiece. This pushes the T-shaped slide bar to compress the contact spring and cause it to contract and deform. This ensures that the contact head can achieve the best matching state each time it is inserted into the workpiece and ensures good contact stiffness to prevent deformation.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a robotic polishing fixture.

[0034] Reference Figure 1 - Figure 3 A robotic polishing fixture includes a processing table 1, with a contact wheel 2 rotatably connected to one end of the processing table 1 and a traction wheel 3 rotatably connected to one end of the processing table 1. A polishing belt 4 is sleeved around the contact wheel 2 and the traction wheel 3. A robotic arm 5 is fixedly connected to one end of the processing table 1. A mounting platform 6 is fixedly connected to the end of the robotic arm 5. A rotary processing slide 7 is symmetrically rotatably connected to one end of the mounting platform 6. An inner support plate 8 is symmetrically slidably connected to one end of the rotary processing slide 7. An outer clamping plate 9 is symmetrically hinged to one end of the rotary processing slide 7. A cylinder 10 is symmetrically hinged to one end of the rotary processing slide 7. The output end of the cylinder 10 is hinged to one end of the outer clamping plate 9. A drive assembly is installed at one end of the processing table 1.

[0035] The drive assembly includes a drive wheel 20 fixedly connected to one end of the processing table 1, one end of the polishing belt 4 passing around the periphery of the drive wheel 20, one end of the drive wheel 20 passing through the processing table 1 and fixedly connected to a worm gear 21, a polishing motor 22 fixedly connected to the outside of the processing table 1, and a worm 23 meshing with the worm gear 21 fixedly connected to the output end of the polishing motor 22.

[0036] When in use, first start the polishing motor 22 to drive the worm 23 to rotate, and drive the worm 23 to mesh with the worm wheel 21. At the same time, the worm wheel 21 drives the drive wheel 20 to rotate. Then, the drive wheel 20, together with the polishing belt 4, drives the contact wheel 2 and the traction wheel 3 to rotate synchronously, so that the polishing belt 4 rotates in a cycle with the contact wheel 2, the traction wheel 3 and the drive wheel 20 as the fulcrum.

[0037] Then, the robot arm 5 is activated to drive the rotary machining slide 7 to embed the inner support plate 8 into the workpiece, and drives the two inner support plates 8 to move away from each other. At the same time, the inner support plates 8 form an inner support against the inner wall of the workpiece to initially fix the workpiece. Then, the cylinder 10 is activated to drive the outer clamping plate 9 to deflect around the hinge axis toward the inner support plate 8. At the same time, the outer clamping plate 9 cooperates with the inner support plate 8 to clamp and fix one end of the workpiece. Next, the robot arm 5 is activated to drive the inner support plate 8 to pull the workpiece toward the outside of the polishing belt 4 and polish the surface of the workpiece. This facilitates the contact between the inner wall of the workpiece and the outer clamping plate 9 when the two inner support plates 8 are in contact with the inner wall of the workpiece, thereby improving the stability of the device in clamping the workpiece and reducing the possibility of the workpiece loosening and falling off.

[0038] Reference Figure 2 - Figure 4 The inner support plate 8 has symmetrically opened adaptive slide grooves 11. T-shaped slide rods 12 are slidably connected inside the adaptive slide grooves 11. One end of each T-shaped slide rod 12 passes through the inner support plate 8 and is fixedly connected to a contact head 13. One end of each T-shaped slide rod 12 is fixedly connected to a contact spring 14, which is installed inside the adaptive slide groove 11.

[0039] One end of the outer clamping plate 9 is provided with an adjustment groove 15. A T-shaped adjustment clamping plate 16 is slidably connected inside the adjustment groove 15. An adjustment screw 17 is rotatably connected inside the adjustment groove 15 and threadedly connected to the T-shaped adjustment clamping plate 16. An adjustment motor 18 is fixedly connected inside the outer clamping plate 9. The output end of the adjustment motor 18 is threadedly connected to the T-shaped adjustment clamping plate 16.

[0040] Furthermore, rubber pads 19 are fixedly connected to one end of both the contact head 13 and the T-shaped adjusting clamp 16.

[0041] When in use, when the robot arm 5 is activated and the inner support plate 8 is inserted into the workpiece, the inner support plate 8 pushes the contact head 13 to form contact with the inside of the workpiece. According to the height of the inside of the workpiece, the contact head 13 is subjected to force to generate contact, and pushes the T-shaped slide bar 12 to compress the contact spring 14 along the length direction of the adaptive slide groove 11 to generate contraction deformation. This ensures that the contact head 13 can achieve the best matching state each time it is inserted into the workpiece and ensures good contact stiffness to avoid deformation.

[0042] Simultaneously, the adjusting motor 18 is started to drive the adjusting screw 17 to rotate, and the adjusting screw 17 forms a threaded connection with the T-shaped adjusting clamp 16, thereby driving the T-shaped adjusting clamp 16 to move along the length direction of the adjusting slide 15 to a length that matches the outer side of the workpiece. Then, when the driving contact head 13 and the T-shaped adjusting clamp 16 respectively form contact with one side of the workpiece, the contact head 13 and the T-shaped adjusting clamp 16 form a flexible contact with the workpiece through the rubber pad 19, so as to reduce the wear between the workpiece and the contact head 13 and the T-shaped adjusting clamp 16, and extend the service life of the device.

[0043] Reference Figure 1 and Figure 2 One end of the processing table 1 is rotatably connected to a fine grinding wheel 24, and one end of the drive wheel 20 is equipped with a transmission assembly;

[0044] The transmission assembly includes a transmission gear 25 fixedly connected to one end of the drive wheel 20, and a fine grinding wheel 24 passing through the processing table 1 and fixedly connected to a transmission gear 26 that meshes with the transmission gear 25.

[0045] When in use, when the polishing motor 22 is started to drive the drive wheel 20 to rotate, the drive wheel 20 drives the transmission gear 1 25 to mesh with the transmission gear 26, and the transmission gear 26 drives the fine grinding wheel 24 to rotate, so that the fine grinding wheel 24 can perform fine grinding on the surface of the workpiece polished by the polishing belt 4, thereby improving the polishing accuracy of the device.

[0046] Reference Figure 1 and Figure 2 The processing table 1 has a water storage tank 27 inside, and a water pump 28 is fixedly connected to the output end of the water storage tank 27. A self-shaping nozzle 29 is fixedly connected to the output end of the water pump 28.

[0047] In use, by starting the water pump 28, the coolant inside the water storage tank 27 can be drawn into the self-shaping nozzle 29, and then the coolant is sprayed onto the surface of the workpiece being polished through the self-shaping nozzle 29 to achieve rapid cooling of the workpiece and improve the practicality of the device.

[0048] The implementation principle of the robotic polishing fixture in this embodiment is as follows: First, the polishing motor 22 is started to drive the worm 23 to rotate, and the worm 23 is driven to mesh with the worm wheel 21. At the same time, the worm wheel 21 drives the drive wheel 20 to rotate. Then, the drive wheel 20, together with the polishing belt 4, drives the contact wheel 2 and the traction wheel 3 to rotate synchronously, so that the polishing belt 4 rotates cyclically with the contact wheel 2, the traction wheel 3, and the drive wheel 20 as the fulcrum.

[0049] Then, the robot arm 5 is activated to drive the rotary processing slide 7 to embed the inner support plate 8 into the workpiece, and drive the two inner support plates 8 to move away from each other. At the same time, the inner support plates 8 form an inner support against the inner wall of the workpiece to initially fix the workpiece. Simultaneously, the contact head 13 is pushed to form an abutment with the inside of the workpiece. According to the height of the workpiece, the contact head 13 is subjected to force to generate abutment, and pushes the T-shaped slide rod 12 to compress the contact spring 14 along the length direction of the adaptive slide groove 11 to generate a contraction deformation. This ensures that the contact head 13 can achieve the best matching state each time it is inserted into the workpiece and ensures good contact stiffness to avoid deformation. At the same time, the adjusting motor 18 is activated to drive the adjusting screw 17 to rotate, and the adjusting screw 17 forms a threaded connection with the T-shaped adjusting clamp 16, thereby driving the T-shaped adjusting clamp 16 to move along the length direction of the adjusting slide groove 15 to a length that matches the outside of the workpiece.

[0050] Then, the cylinder 10 is started to drive the outer clamping plate 9 to deflect around the hinge axis toward the inner support plate 8. At the same time, the outer clamping plate 9 and the inner support plate 8 clamp and fix one end of the workpiece. Then, the robot arm 5 is started to drive the inner support plate 8 to pull the workpiece to the outside of the polishing belt 4 and polish the surface of the workpiece. When the polishing motor 22 is started to drive the drive wheel 20 to rotate, the drive wheel 20 drives the transmission gear 1 25 to mesh with the transmission gear 26, and the transmission gear 26 drives the fine grinding wheel 24 to rotate, so that the fine grinding wheel 24 can perform fine grinding on the surface of the workpiece after polishing by the polishing belt 4.
