Technical Field

[0001] The invention relates to the technical field of automobile glass processing, in particular to a polishing device for automobile skylight glass. Background Art

[0002] With the continuous development of economy, people's material living standards are increasing day by day, and the demand for cars is also gradually increasing. In order to improve the comfort of travel, people will choose cars with sunroof glass when buying cars. In order to beautify the overall appearance of the car, most car sunroof glass will adopt a streamlined curved surface design, which also increases the difficulty of car sunroof glass processing.

[0003] At present, the polishing of car sunroof glass is mostly done manually by workers using a polishing machine. Since car sunroof glass is mostly designed as a curved surface, when workers place the car sunroof glass on a work surface for polishing, the glass may shake left and right during polishing due to the setting of the curved surface, thereby affecting the polishing quality.

[0004] Therefore, we designed a polishing device for automobile sunroof glass to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a polishing device for automobile sunroof glass to solve the problems raised in the above background technology.

A lever is connected to the inside of the two mounting round blocks for common rotation, a tension spring is fixedly arranged at the bottom of one end of the lever, and the other end of the tension spring is fixedly connected to the side of the fixed block, and a suction cup is fixedly arranged on the top of the other end of the lever.

[0007] Furthermore, a mounting seat is fixedly provided on the side of the other end of the lever, the interior of the mounting seat is rotatably connected to a limiting rod, a limiting groove is provided on the top of the workbench, and the other end of the limiting rod is inserted into the interior of the limiting groove.

[0008] Furthermore, the bottom of the limiting rod is slidably connected to a sliding base, a cavity is provided inside the sliding base, the bottom of the cavity is fixedly connected to two compression springs, and the top of each compression spring is fixedly connected to the bottom of the limiting rod.

[0009] Furthermore, both sides of the top of the limit rod are provided with sliding grooves, and a limit spring is fixedly provided on one side surface of each slide groove. The other end of the limit spring is fixedly connected to a slider, and the other end of the slider is fixedly connected to a semicircular block, and the slider is slidably connected in the slide groove.

[0010] Furthermore, both sides of the limiting groove are provided with clamping grooves, and the arc surface of the semicircular clamping block abuts against the inner wall surface of the clamping groove.

[0011] Furthermore, upright posts are fixedly arranged around the top of the workbench, and the tops of the four upright posts are commonly and fixedly connected to a top seat.

[0012] Furthermore, limit plates are fixedly provided at both ends of the top of the top seat, a hydraulic cylinder is fixedly provided on one side of the limit plate at one end, a moving platform is fixedly provided at the other end of the hydraulic cylinder, and both ends of the bottom of the moving platform are slidably plugged into both sides of the top seat.

[0013] Furthermore, a pneumatic push rod is fixedly arranged at the bottom of the movable platform, and a polishing tool is rollingly connected to the other end of the pneumatic push rod.

[0014] Compared with the prior art, the beneficial effect of the present invention is that through the action of the gravity of the automobile sunroof glass, the lever will rotate around the rotating shaft arranged inside the mounting circle, the end of the lever provided with the suction cup will be pressed down, and the other end of the lever will rise, and the tension spring will be stretched under the action of the lever, generating a downward elastic force on the lever, which not only generates a damping for the rotation of the lever, but also limits the lever to prevent the lever from rotating to the lowest point under the action of the gravity of the automobile sunroof glass and failing to adsorb the automobile sunroof glass, and by clamping the automobile sunroof glass, the automobile sunroof glass is prevented from shaking left and right during polishing, thereby improving the polishing quality of the automobile sunroof glass.

[0015] Compared with the prior art, the beneficial effect of the present invention is that through the rotation of the lever, since the connection between the top of the limit rod and the mounting seat is very loose, the limit rod will always be in a state perpendicular to the workbench, and during the rotation of the lever, the limit rod will continue to move, and when the bottom of the sliding base arranged at the bottom of the limit rod contacts the bottom surface of the limit groove, the sliding base moves horizontally, and the limit rod will slide along the inner wall surface of the sliding base toward the bottom of the cavity for an end distance until the arc surface of the semicircular block abuts against the surface of the slot, thereby limiting the lever and avoiding the situation where the lever rotates excessively and the suction cup cannot adsorb the car sunroof glass.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-6 The present invention provides a technical solution: a polishing device for automobile sunroof glass, comprising a workbench 1, four fixed blocks 2 are fixedly arranged on the top of the workbench 1, mounting round blocks 3 are fixedly arranged on both sides of the top of each fixed block 2, a lever 4 is connected to the inside of the two mounting round blocks 3 for common rotation, a tension spring 5 is fixedly arranged at the bottom of one end of the lever 4, the other end of the tension spring 5 is fixedly connected to the side of the fixed block 2, and a suction cup 6 is fixedly arranged on the top of the other end of the lever 4.

[0020] In specific implementation, when polishing the car sunroof glass, first place the car sunroof glass on the top of the suction cup 6. Under the action of the gravity of the car sunroof glass, the lever 4 will rotate around the rotating shaft set inside the mounting circle 3. The end of the lever 4 provided with the suction cup 6 is pressed down, and the other end of the lever 4 rises. The tension spring 5 will be stretched under the action of the lever 4, and a downward elastic force will be generated on the lever 4, which not only generates a damping for the rotation of the lever 4, but also limits the lever 4 to prevent the lever 4 from rotating to the lowest end of the lever 4 provided with the suction cup 6 under the action of the gravity of the car sunroof glass and failing to adsorb the car sunroof glass.

[0021] It should be noted that the suction cup 6 here is a vacuum suction cup, and a vacuum pump is provided at the bottom of the suction cup 6. The suction cup 6 is adsorbed on the car sunroof glass by the negative pressure generated by the vacuum pump. Since the surface of the car sunroof glass is flat, the suction cup 6 can be well adsorbed on the surface of the car sunroof glass. By pressing the vacuum pump to discharge the air in the suction cup 6, negative pressure is formed, thereby fixing the car sunroof glass.

[0022] See also Figure 1-6 As shown, a mounting seat 7 is fixedly provided on the side of the other end of the lever 4, and a limiting rod 8 is rotatably connected inside the mounting seat 7. A limiting groove 9 is provided on the top of the workbench 1, and the other end of the limiting rod 8 is inserted into the inside of the limiting groove 9.

[0023] In a specific implementation, when the lever 4 rotates, since the connection between the top of the limit rod 8 and the mounting seat 7 is very loose, the limit rod 8 will always be in a state perpendicular to the workbench 1. During the rotation of the lever 4, the limit rod 8 will continuously move in an arc.

[0024] See also Figure 1-6 The bottom of the limiting rod 8 is slidably connected to a sliding base 11, a cavity 12 is opened inside the sliding base 11, and two compression springs 13 are fixedly connected to the bottom of the cavity 12, and the top of each compression spring 13 is fixedly connected to the bottom of the limiting rod 8.

[0025] During specific implementation, when the bottom of the sliding base 11 provided at the bottom of the limiting rod 8 contacts the bottom surface of the limiting groove 9, the sliding base 11 moves horizontally, and the limiting rod 8 slides along the inner wall surface of the sliding base 11 toward the bottom of the cavity 12 for a distance until the arc surface of the semicircular block 17 abuts against the surface of the groove 10.

[0026] It should be noted that the compression spring 13 here has an upward elastic force on the limit rod 8, and under the action of this elastic force, a damping is generated on the descent of the limit rod 8, so that the limit rod 8 can descend slowly, avoiding the situation where the limit rod 8 descends too quickly and the semicircular block 17 cannot be stuck in the slot 10.

[0027] See also Figure 1-6 Slide grooves 14 are provided on both sides of the top of the limit rod 8, and a limit spring 15 is fixedly provided on one side surface of each slide groove 14. The other end of the limit spring 15 is fixedly connected to a slider 16, and the other end of the slider 16 is fixedly connected to a semicircular block 17. The slider 16 is slidably connected in the slide groove 14.

[0028] During specific implementation, before the arc surface of the semicircular block 17 abuts against the surface of the slot 10, the arc surface of the semicircular block 17 is squeezed by the two side surfaces of the limiting groove 9 and is located inside the slide groove 14. At this time, the limiting spring 15 is always in a compressed state. Until the semicircular block 17 moves to the position of the slot 10, the limiting spring 15 will push the slider 16 to make the semicircular block 17 abut against the surface of the slot 10. In this process, the slide groove 14 is always in a compressed state, and there is an elastic force on the slider 16 toward the outside of the limiting rod 8 to ensure that the arc surface of the semicircular block 17 always abuts against the inner wall surface of the slot 10. At this time, the bottom surface of the sliding base 11 also abuts against the bottom surface of the limiting groove 9, and the elastic force of the clamping spring 13 and the elastic force of the limiting spring 15 cooperate with each other to prevent the limiting rod 8 from sliding down.

[0029] It should be noted that the limit spring 15 here cooperates with the clamping spring 13 to limit the limit rod 8. When the semicircular block 17 is stuck in the slot 10, since the clamping spring 13 is in a compressed state, the clamping spring 13 has an upward elastic force on the limit rod 8, and the friction force of the slot 10 on the semicircular block 17 is also upward, so the limit rod 8 will not continue to move. Before the semicircular block 17 is stuck in the slot 10, since the elastic force of the clamping spring 13 on the limit rod 8 is very small, the limit rod 8 can continue to descend.

[0030] See also Figure 1-6 A clamping groove 10 is provided on both sides of the limiting groove 9 , and the arc surface of the semicircular clamping block 17 abuts against the inner wall surface of the clamping groove 10 .

[0031] In specific implementation, the arc surface of the semicircular block 17 abuts against the inner wall surface of the slot 10, so that the limiting rod 8 stops moving, thereby stopping the lever 4 from rotating, and cooperates with the tension spring 5 at one end of the lever 4 to limit the lever 4.

[0032] See also Figure 1-6, columns 18 are fixedly arranged around the top of the workbench 1, and a top seat 24 is fixedly connected to the tops of the four columns 18. Limit plates 19 are fixedly arranged at both ends of the top of the top seat 24, a hydraulic cylinder 20 is fixedly arranged on one side of the limit plate 19 at one end, and a moving platform 21 is fixedly arranged at the other end of the hydraulic cylinder 20. The two ends of the bottom of the moving platform 21 are slidably inserted into the two sides of the top seat 24, and a pneumatic push rod 22 is fixedly arranged at the bottom of the moving platform 21, and a polishing tool 23 is rollingly connected to the other end of the pneumatic push rod 22.

[0033] During specific implementation, after the automobile sunroof glass is clamped, the telescopic end of the hydraulic cylinder 20 arranged on one side of the limit plate 19 is extended to push out the moving platform 21. At the same time when the moving platform 21 is pushed out, the pneumatic push rod 22 descends to a suitable position and makes the lower surface of the polishing tool 23 stick to the surface of the automobile sunroof glass to polish the automobile sunroof glass. The polishing tool 23 is rotatably connected to the bottom end of the pneumatic push rod 22, so that automobile sunroof glasses with different curvatures can be polished by rotating the polishing tool 23 at different angles.

[0034] The motor drives the polishing disc to rotate at high speed. The polishing disc and the polishing agent work together to remove the bumps on the surface of the car sunroof glass by rubbing against the surface of the car sunroof glass, thereby ensuring the smoothness of the surface of the car sunroof glass.

[0035] It should be noted that the hydraulic cylinder 20 here controls the extension or shortening of its telescopic end through a button. When the moving platform 21 moves, the telescopic end of the pneumatic push rod 22 is extended at the same time, and an infrared sensor is provided inside the polishing tool 23. When the polishing tool 23 is in contact with the car sunroof glass, the telescopic end of the pneumatic push rod 22 will no longer extend.

[0036] It should be noted that a universal ball is provided on the top of the polishing tool 23, under the action of the universal ball, the polishing tool 23 can rotate in any direction. Since the bottom surface of the polishing tool 23 is in contact with the surface of the car sunroof glass, the bottom surface of the polishing tool 23 can always be in contact with the surface of the car sunroof glass, thereby completing the polishing process of the car sunroof glass.

[0037] It should be noted that the hydraulic cylinder 20 here uses the pressure of hydraulic oil to act on the piston to convert hydraulic energy into mechanical energy to achieve linear reciprocating motion. The hydraulic cylinder 20, also known as the oil cylinder or the actuator, is an actuator in the hydraulic transmission system, used to drive the working mechanism to perform linear reciprocating motion. The hydraulic cylinder 20 converts hydraulic energy into mechanical energy by acting on the piston through the pressure of hydraulic oil. The effective working area of ​​the piston directly affects the force and movement speed of the hydraulic cylinder.

[0038] It should be noted that the pneumatic push rod 22 here is a device that uses compressed air to generate thrust. The pneumatic push rod 22 is mainly composed of a cylinder, a piston, a piston rod, a valve and other components. When air pressure is applied to the cylinder, the piston is pressed and pushes the piston rod outward, thereby generating thrust. The magnitude of this thrust depends on the magnitude of the air pressure, the size of the push rod and other possible resistance factors. The pneumatic push rod 22 here is also controlled by a control button, and the start and stop of the pneumatic push rod 22 is carried out simultaneously with the start and stop of the hydraulic cylinder 20.

[0039] Working principle: When polishing the car sunroof glass, first place the car sunroof glass on the top of the suction cup 6. Under the action of the gravity of the car sunroof glass, the lever 4 will rotate around the rotating shaft set inside the mounting circle 3, and the end of the lever 4 with the suction cup 6 will be pressed down, while the other end of the lever 4 will rise. The tension spring 5 will be stretched under the action of the lever 4, generating a downward elastic force on the lever 4, which not only generates a damping for the rotation of the lever 4, but also limits the lever 4 to prevent the lever 4 from rotating to the lowest end with the suction cup 6 under the action of the gravity of the car sunroof glass and failing to adsorb the car sunroof glass.

[0040] When the lever 4 rotates, since the connection between the top of the limit rod 8 and the mounting seat 7 is very loose, the limit rod 8 will always be in a perpendicular state to the workbench 1. During the rotation of the lever 4, the limit rod 8 will continue to move. When the bottom of the sliding base 11 provided at the bottom of the limit rod 8 contacts the bottom surface of the limit groove 9, the sliding base 11 moves horizontally at this time, and the limit rod 8 will slide an end distance along the inner wall surface of the sliding base 11 toward the bottom of the cavity 12 until the arc surface of the semicircular block 17 abuts against the surface of the groove 10.

[0041] Before the arc surface of the semicircular block 17 abuts against the surface of the slot 10, the arc surface of the semicircular block 17 is squeezed by the two side surfaces of the limiting groove 9 and is located inside the slide groove 14. At this time, the limiting spring 15 is always in a compressed state. Until the semicircular block 17 moves to the position of the slot 10, the limiting spring 15 will push the slider 16 to make the semicircular block 17 abut against the surface of the slot 10. In this process, the slide groove 14 is always in a compressed state, and the slider 16 has an elastic force toward the outside of the limiting rod 8 to ensure that the arc surface of the semicircular block 17 always abuts against the inner wall surface of the slot 10. At this time, the bottom surface of the sliding base 11 also abuts against the bottom surface of the limiting groove 9, and the elastic force of the clamping spring 13 and the elastic force of the limiting spring 15 cooperate with each other to prevent the limiting rod 8 from sliding down.

[0042] The rotation angles of the lever 4 for automobile sunroof glasses of different curvatures are different, so the downward movement distances of the limiting rod 8 are different, so that the limiting rod 8 limits the lever 4 at different positions in the limiting groove 9 .

[0043] After the car sunroof glass is clamped, the telescopic end of the hydraulic cylinder 20 arranged on one side of the limit plate 19 extends to push out the moving platform 21. At the same time when the moving platform 21 is pushed out, the pneumatic push rod 22 descends to a suitable position and makes the lower surface of the polishing tool 23 stick to the surface of the car sunroof glass to polish the car sunroof glass. The polishing tool 23 is rotatably connected to the bottom end of the pneumatic push rod 22, so that car sunroof glasses with different curvatures can be polished by rotating the polishing tool 23 at different angles.

[0044] The motor drives the polishing disc to rotate at high speed. The polishing disc and the polishing agent work together to remove the bumps on the surface of the car sunroof glass by rubbing against the surface of the car sunroof glass, thereby ensuring the smoothness of the surface of the car sunroof glass.
