Abstract
Description
Technical Field
[0001] The invention relates to the technical field of polishing, in particular to a dust-free motorcycle frame robot polishing device. Background Art
[0002] In the manufacturing process of motorcycle frames, the flash and burrs generated by welding are mostly concentrated in the narrow angle area formed by the intersection of pipes, such as the rear fork connection triangle area, the engine suspension point gap, etc. Such spaces often have process difficulties with an opening angle less than 30° and a gap width of 5-10mm. Traditional grinding equipment faces two major technical bottlenecks. First, conventional straight-shank grinding wheels (such as φ50mm cup grinding wheels) cannot reach deep and narrow gaps due to geometric size interference. Actual measurements show that the coverage rate of the angle area of the frame by existing robot grinding equipment is less than 40%, resulting in about 35% of the welding slag requiring manual handheld angle grinder grinding, low operating efficiency and poor consistency. When a miniaturized fixed grinding head is forcibly intervened, it is very easy to cause damage to the surface of thin-walled pipes due to uneven force, interference from the robotic arm, and cause deformation. Summary of the invention
[0003] The object of the present invention is to provide a dust-free motorcycle frame robot grinding device to solve the problems raised in the prior art.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dust-free motorcycle frame robot polishing equipment, comprising a robotic arm, a polishing assembly and a clamping table, a curved slide rail is arranged on one side of the clamping table, a moving module is arranged on the curved slide rail, the moving module is connected to the control system through a circuit, the robotic arm is mounted on the moving module, the polishing assembly is mounted on the execution end of the robotic arm, a displacement plate and an auxiliary plate are symmetrically mounted on the clamping table, a clamp is rotatably mounted on the displacement plate and the auxiliary plate, and a pair of the clamps are used to clamp the motorcycle frame.
[0005] Furthermore, a double-headed screw and a rotating shaft are rotatably installed inside the clamping platform, and the two sections of the double-headed screw have opposite directions of thread. Screw holes are provided at the bottom of the displacement upright plate and the auxiliary upright plate, and the displacement upright plate and the auxiliary upright plate are screwed together with the double-headed screw through the screw holes. A worm gear is integrally provided at the middle of the double-headed screw, and the rotating shaft is located below the worm gear. A worm is provided on the rotating shaft, and the worm is meshed with the worm gear. One end of the rotating shaft passes through the clamping platform, and a handwheel is provided at one end of the rotating shaft. The operator drives the worm to rotate by turning the handwheel, and the worm drives the worm wheel to rotate, and the worm wheel drives the double-headed screw to rotate, and the double-headed screw drives the displacement upright plate and the auxiliary upright plate to move. Since the two sections of the double-headed screw have opposite directions of thread, the displacement upright plate and the auxiliary upright plate move away from or closer to each other, and the spacing between a pair of clamps is adjusted to match the actual size of the motorcycle frame, so as to better clamp the motorcycle frame.
[0006] Furthermore, the displacement plate and the auxiliary plate are each connected to a dust baffle, the dust baffle is in contact with the surface of the clamping table, the clamp on the displacement plate is coaxially connected with a driven bevel gear, a first servo motor is arranged on the side of the displacement plate away from the auxiliary plate, an active bevel gear is mounted on the motor shaft of the first servo motor, the active bevel gear is meshingly connected with the driven bevel gear, during the grinding process, the control system drives the first servo motor to drive the clamp to rotate, and cooperates with the mechanical arm to drive the movement of the polishing assembly, so as to realize all-round grinding of the motorcycle frame.
[0007] Furthermore, the displacement upright plate and the auxiliary upright plate are made of metal material, the displacement upright plate is connected to the positive pole of the circuit, and the auxiliary upright plate is connected to the negative pole of the circuit. After the displacement upright plate and the auxiliary upright plate are energized, the air near the displacement upright plate is ionized and attracted by the auxiliary upright plate, generating an airflow from the displacement upright plate to the auxiliary upright plate, and the grinding debris generated during the grinding process moves toward the auxiliary upright plate driven by the airflow, preventing the grinding debris from dispersing and falling in the workplace, so as to facilitate the collection and cleaning of the grinding debris.
[0008] Furthermore, the polishing assembly includes a second servo motor and a polishing outer cover, the motor shaft of the second servo motor is connected to the polishing outer cover, a grinding body is arranged on the outer wall of the polishing outer cover, a convex strip is arranged on the inner wall of the polishing outer cover, a sealing sliding disk is sealingly connected inside the polishing outer cover, the sealing sliding disk slides along the direction of the convex strip, the robotic arm drives the polishing assembly to move, the second servo motor drives the polishing outer cover to rotate, and the grinding body polishes the motorcycle frame.

If it is necessary to grind a relatively narrow angle or gap on the motorcycle frame, the grinding body outside the grinding cover cannot extend into it, and therefore a conical grinding body is required for further grinding. The sealing sliding plate drives the adapter plate to move at the same time during the movement, and the protrusion of the adapter plate slides in the spiral groove, forcing the adapter plate to rotate at the bottom of the sealing sliding plate.
[0010] Furthermore, the sealing slide plate and the adapter plate are evenly provided with an equal number of slide grooves, and the polishing assembly includes several split conical grinding parts, each of which is provided with a pin at the upper end, and a slider is provided above each of the pins, and the slider is slidably installed in the slide groove on the sealing slide plate, and the pin is slidably installed in the slide groove on the adapter plate.

[0011] Furthermore, an annular groove is provided on the top of the polishing outer cover, and several through holes are provided between the annular groove and the inside of the polishing outer cover. An air supply ring is installed with a rotating seal in the annular groove, and the air supply ring is connected to the pneumatic system through a pipeline. Since the polishing outer cover and the sealing sliding disk are in a sealed sliding state, even if the sealing sliding disk moves to the position of the spiral groove, the protrusion on the adapter plate also maintains a sealed sliding connection with the spiral groove. Therefore, the space between the top of the polishing outer cover and the sealing sliding disk is a closed space. The air supply ring can supply air to the closed space through the pneumatic system when the polishing outer cover is rotating, and the air pressure is used to drive the sealing sliding disk to move. When the split conical polishing part needs to be retracted, the pneumatic system extracts the gas in the closed space, and the split conical polishing part is retracted into the polishing outer cover, thereby reducing the space occupied by the polishing part, so that the polishing outer cover can be polished more flexibly.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The operator turns the hand wheel to drive the displacement plate and the auxiliary plate to move away from or towards each other, and adjusts the spacing between a pair of clamps to match the actual size of the motorcycle frame, so as to better clamp the motorcycle frame; 2.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] Example: Figures 1-7As shown in the figure, the present invention provides a technical solution, a dust-free motorcycle frame robot grinding device, including a robotic arm 1, a polishing assembly 4 and a clamping table 5. A curved slide rail 3 is provided on one side of the clamping table 5, and a moving module 2 is provided on the curved slide rail 3. The moving module 2 is connected to the control system through a circuit. The robotic arm 1 is installed on the moving module 2, and the polishing assembly 4 is installed at the execution end of the robotic arm 1. Displacement vertical plates 6 and auxiliary vertical plates 7 are symmetrically installed on the clamping table 5. Clamps 8 are rotatably installed on both the displacement vertical plate 6 and the auxiliary vertical plate 7. A pair of clamps 8 clamp the motorcycle frame. A double-headed screw 12 and a rotating shaft 15 are rotatably installed inside the clamping table 5. The two sections of the double-headed screw 12 have opposite thread directions. Screw holes are opened at the bottoms of the displacement vertical plate 6 and the auxiliary vertical plate 7. The displacement vertical plate 6 and the auxiliary vertical plate 7 are screwed to the double-headed screw 12 through the screw holes. A worm gear 13 is integrally provided in the middle of the double-headed screw 12. The rotating shaft 15 is located below the worm gear 13. A worm 14 is provided on the rotating shaft 15. The worm 14 meshes with the worm gear 13. One end of the rotating shaft 15 penetrates through the clamping table 5, and a handwheel 16 is provided at one end of the rotating shaft 15. The operator drives the worm 14 to rotate by rotating the handwheel 16. The worm 14 drives the worm gear 13 to rotate. The worm gear 13 drives the double-headed screw 12 to rotate. The double-headed screw 12 drives the displacement vertical plate 6 and the auxiliary vertical plate 7 to move. Since the two sections of the double-headed screw 12 have opposite thread directions, the displacement vertical plate 6 and the auxiliary vertical plate 7 move away from each other or move closer to each other, adjusting the distance between a pair of clamps 8 to match the actual size of the motorcycle frame, facilitating better clamping of the motorcycle frame.
[0017] A dust-proof baffle 17 is connected to both the displacement vertical plate 6 and the auxiliary vertical plate 7. The dust-proof baffle 17 is in contact with the surface of the clamping table 5. The clamp 8 located on the displacement vertical plate 6 is coaxially connected with a driven bevel gear 9. A first servo motor 11 is provided on the side of the displacement vertical plate 6 away from the auxiliary vertical plate 7. A driving bevel gear 10 is installed on the motor shaft of the first servo motor 11. The driving bevel gear 10 is meshed and connected with the driven bevel gear 9. The displacement vertical plate 6 and the auxiliary vertical plate 7 are made of metal materials. The displacement vertical plate 6 is connected to the positive pole of the circuit, and the auxiliary vertical plate 7 is connected to the negative pole of the circuit. During the grinding process, the control system drives the first servo motor 11 to drive the clamp 8 to rotate, cooperating with the movement of the robotic arm 1 driving the polishing assembly 4 to achieve all-round grinding of the motorcycle frame. After the displacement vertical plate 6 and the auxiliary vertical plate 7 are energized, the air near the displacement vertical plate 6 is ionized and attracted by the auxiliary vertical plate 7, generating an air flow flowing from the displacement vertical plate 6 to the auxiliary vertical plate 7. The grinding debris generated during the grinding process moves towards the direction of the auxiliary vertical plate 7 under the drive of the air flow, preventing the grinding debris from dispersing and falling in the working site, facilitating the collection and cleaning of the grinding debris.
[0018] The polishing assembly 4 includes a second servo motor 18 and a polishing outer cover 19, the motor shaft of the second servo motor 18 is connected to the polishing outer cover 19, a grinding body is arranged on the outer wall of the polishing outer cover 19, a convex strip is arranged on the inner wall of the polishing outer cover 19, a sealing sliding disc 21 is sealed and slidably connected inside the polishing outer cover 19, and the sealing sliding disc 21 slides along the direction of the convex strip, the polishing assembly 4 includes a spiral groove column 20 and an adapter disc 23, the spiral groove column 20 is arranged in the middle of the polishing outer cover 19, the spiral groove column 20 passes through the sealing sliding disc 21, a spiral groove is opened on the spiral groove column 20, the adapter disc 23 is installed under the sealing sliding disc 21, and the adapter disc 23 is installed Mounted on the spiral groove column 20, a protrusion is arranged on the adapter plate 23, and the protrusion is slidably arranged in the spiral groove. The mechanical arm 1 drives the polishing assembly 4 to move, and the second servo motor 18 drives the grinding cover 19 to rotate. The grinding body grinds the motorcycle frame. If it is necessary to grind a relatively narrow angle or gap on the motorcycle frame, the grinding body outside the grinding cover 19 cannot extend into it, so it is necessary to use a conical grinding body for further grinding. The sealing sliding plate 21 drives the adapter plate 23 to move at the same time during the movement, and the protrusion of the adapter plate 23 slides in the spiral groove, forcing the adapter plate 23 to rotate at the bottom of the sealing sliding plate 21.
[0019] The sealing slide plate 21 and the adapter plate 23 are evenly provided with the same number of slide grooves. The polishing assembly 4 includes several split conical grinding pieces 26. A pin 25 is provided on the upper end of each split conical grinding piece 26. A slider 24 is provided above each pin 25. The slider 24 is slidably installed in the slide groove on the sealing slide plate 21. The pin 25 is slidably installed in the slide groove on the adapter plate 23. An annular groove is provided on the top of the grinding cover 19. Several through holes are provided between the annular groove and the inside of the grinding cover 19. An air supply ring 22 is rotatably installed in the annular groove. The air supply ring 22 is connected to the pneumatic system (not shown in the figure) through a pipeline. After the adapter plate 23 rotates, the slide grooves on the sealing slide plate 21 and the adapter plate 23 are staggered from each other. The staggered oblique distribution of the slide grooves is used to push the pin 25 to slide. The slider 24 controls the sliding direction of the split conical grinding piece 26, that is, the split conical grinding piece 26 is close to each other along the radial direction until it rotates. The receiving plate 23 moves to the end of the spiral groove column 20, and the adapter plate 23 rotates to the extreme position. All the split conical grinding pieces 26 are closed into a cone shape, thereby realizing the grinding of relatively narrow angles or gaps on the motorcycle frame. Since the grinding cover 19 and the sealing sliding plate 21 are in a sealed sliding state, even if the sealing sliding plate 21 moves to the position of the spiral groove, the protrusion on the adapter plate 23 also maintains a sealed sliding connection with the spiral groove. Therefore, the space between the top of the grinding cover 19 and the sealing sliding plate 21 is a closed space. The air supply ring 22 can supply air to the closed space through the pneumatic system when the grinding cover 19 is rotating, and the air pressure is used to drive the sealing sliding plate 21 to move. When it is necessary to retract the split conical grinding piece 26, the pneumatic system extracts the gas in the closed space, and the split conical grinding piece 26 is retracted into the grinding cover 19, thereby reducing the space occupied by the grinding piece, so that the grinding cover 19 can be polished more flexibly.
[0020] The working principle of the present invention is as follows: the operator drives the worm 14 to rotate by turning the hand wheel 16, the worm 14 drives the worm wheel 13 to rotate, the worm wheel 13 drives the double-headed screw 12 to rotate, and the double-headed screw 12 drives the displacement plate 6 and the auxiliary plate 7 to move. Since the two sections of the thread of the double-headed screw 12 are in opposite directions, the displacement plate 6 and the auxiliary plate 7 move away from or towards each other, and the spacing between a pair of clamps 8 is adjusted to match the actual size of the motorcycle frame, so as to better clamp the motorcycle frame.
[0021] During the grinding process, the control system drives the first servo motor 11 to drive the clamp 8 to rotate, and cooperates with the robot arm 1 to drive the movement of the polishing assembly 4 to achieve all-round grinding of the motorcycle frame. After the displacement plate 6 and the auxiliary plate 7 are energized, the air near the displacement plate 6 is ionized and attracted by the auxiliary plate 7, generating an airflow from the displacement plate 6 to the auxiliary plate 7. The grinding debris generated during the grinding process moves toward the auxiliary plate 7 driven by the airflow, preventing the grinding debris from dispersing and falling in the workplace, so as to facilitate the collection and cleaning of the grinding debris.
[0022] The robotic arm 1 drives the polishing assembly 4 to move, and the second servo motor 18 drives the grinding cover 19 to rotate, and the grinding body grinds the motorcycle frame. If it is necessary to grind a relatively narrow angle or gap on the motorcycle frame, the grinding body outside the grinding cover 19 cannot extend into it, so it is necessary to use a conical grinding body for further grinding. During the movement, the sealing slide plate 21 drives the adapter plate 23 to move at the same time, and the protrusion of the adapter plate 23 slides in the spiral groove, forcing the adapter plate 23 to rotate at the bottom of the sealing slide plate 21.
[0023] After the adapter plate 23 rotates, the sealing slide plate 21 and the slide grooves on the adapter plate 23 are staggered with each other, and the staggered oblique directions of the slide grooves are used to push the pin 25 to slide, and the slider 24 controls the sliding direction of the split conical grinding piece 26, that is, the split conical grinding pieces 26 are close to each other along the radial direction until the adapter plate 23 moves to the end of the spiral groove column 20, and the adapter plate 23 rotates to the limit position, and all the split conical grinding pieces 26 are closed into a cone shape, and then the relatively narrow angles or gaps on the motorcycle frame are polished. Since the polishing cover 19 and the sealing slide plate 21 are in a sealed sliding state, even if the sealing The sealing sliding disk 21 moves to the position of the spiral groove, and the protrusion on the adapter disk 23 also maintains a sealed sliding connection with the spiral groove. Therefore, the space between the top of the grinding cover 19 and the sealing sliding disk 21 is a closed space. The air supply ring 22 can supply air to the closed space through the pneumatic system when the grinding cover 19 is rotating, and the air pressure is used to drive the sealing sliding disk 21 to move. When it is necessary to retract the split conical grinding part 26, the pneumatic system extracts the gas in the closed space, and the split conical grinding part 26 is retracted into the grinding cover 19, thereby reducing the space occupied by the grinding parts, so that the grinding cover 19 can be polished more flexibly.
