[0030] The suspension seat 1 is used to fix the moving slide of the grinding line of the grinding equipment. The suspension seat 1 is also used to support the installation of other components.
[0031] The lifting mechanism 2 includes a lifting screw 21, a lifting nut 22, a guide rail 23, a lifting slide 24, and a third motor 25. The lifting screw 21 is vertically positioned and rotatably supported on the suspension seat 1 via bearing seats at both ends. The lifting nut 22 is threadedly engaged with the lifting screw 21. The guide rail 23 is mounted on the suspension seat 1 and parallel to the lifting screw 21. In this embodiment, there are two guide rails 23, symmetrically arranged on both sides of the lifting screw 21. The lifting slide 24 is fixedly connected to the lifting nut 22 and slidably engaged with the guide rail 23. The third motor 25 is mounted on the suspension seat 1 and is drively connected to the upper end of the lifting screw 21. In this embodiment, the output shaft of the third motor 25 is connected to the upper end of the lifting screw 21 via a coupling. Thus, the third motor 25 can drive the lifting screw 21 to rotate, thereby causing the lifting slide 24 to move up and down via the lifting nut 22, adjusting the height of the lifting slide 24.
[0032] The lifting slide 24 is equipped with a mounting base 5, which forms a cantilever structure with the lifting slide 24. The middle of the mounting base 5 is a clearance hole. The mounting base 5 can move up and down synchronously with the lifting slide 24.
[0033] A hollow rotating platform 6 is provided on the lower side of the mounting base 5. The hollow rotating platform 6 adopts existing technology. A first motor 61 is provided on one side of the upper end of the hollow rotating platform 6, and the lower end of the hollow rotating platform 6 is the load end. A guide rail seat 62 is provided on the load end of the hollow rotating platform 6. A clearance hole is also provided in the middle of the guide rail seat 62. A linear guide rail 63 is provided on each side of the lower surface of the guide rail seat 62. The first motor 61 can drive the guide rail seat 62 to rotate through the hollow rotating platform 6.
[0034] The grinding head drive mechanism 4 includes a clamp 41, a main shaft 42, and a second motor 43. The clamp 41 is located below the linear guide rails 63 and slides with the two linear guide rails 63. The second motor 43 is located on the upper side of the clamp 41 and inside the hollow rotating platform 6. The output shaft of the second motor 43 faces downward. The upper end of the main shaft 42 is connected to the output shaft of the second motor 43 through a coupling.
[0035] The grinding head assembly 3 includes a tool holder 31, a coarse grinding wheel 32, and a polishing wheel 33. The upper end of the tool holder 31 is detachably connected to the lower end of the spindle 42. The coarse grinding wheel 32 and the polishing wheel 33 are located at the lower end of the tool holder 31 and their axes coincide. A shim can be provided between the coarse grinding wheel 32 and the polishing wheel 33 to separate them. In this embodiment, the polishing wheel 33 is located below the coarse grinding wheel 32.
[0036] The grinding head position adjustment mechanism 7 includes a first cylinder 71 and a second cylinder 72. The first cylinder 71 is supported on the side of the guide rail seat 62 by a first support block 73. After the extension rod of the first cylinder 71 extends, its front end abuts against the side of the clamp 41, and can push the clamp 41 to move along the length direction of the linear guide rail 63. The second cylinder 72 is supported on the guide rail seat 62 by a second support block 74 and is located on the opposite side of the first cylinder 71. After the extension rod of the second cylinder 72 extends, its front end abuts against the side of the clamp 41, and can push the clamp 41 to move towards the first cylinder 71. The front ends of the extension rods of the first cylinder 71 and the second cylinder 72 can be provided with protective pads. The protective pads can be made of flexible material, so that they can play a buffering role when the extension rods of the cylinders contact the clamp 41, and also reduce the noise of the collision.
[0037] The second support block 74 is also provided with a limiting screw 75. The second support block 74 is provided with a threaded hole, and the limiting screw is fixed at the threaded hole. The front end of the limiting screw is located inside the second support block 74 and faces the clamp 41, and is at the same height as the side of the clamp 41. The number of limiting screws can be two or more. The limiting screw is used to limit the position of the clamp 41 moving toward the second cylinder 72, and at the same time works with the first cylinder 71 to clamp the clamp 41.
[0038] The module also includes a protective cover 8, which covers the lifting mechanism 2, the grinding head assembly 3, the grinding head drive mechanism 4, and the grinding head position adjustment mechanism 7. The lower end of the protective cover 8 is open, and the coarse grinding wheel 32 and the polishing wheel 33 pass through the lower end of the protective cover 8. The protective cover 8 not only provides safety protection for the internal working mechanism, but also serves as a dustproof function.
[0039] The lower end of the protective cover 8 is provided with an annular water spray pipe 81, and the lower side of the annular water spray pipe 81 is provided with water spray nozzles 82. The outlet of the water spray nozzles 82 faces the coarse grinding wheel 32 and the polishing wheel 33. There are multiple water spray nozzles 82, which are distributed at intervals along the circumference of the annular water spray pipe 81. The liquid flowing from the water spray nozzles 82 is sprayed onto the coarse grinding wheel 32 and the polishing wheel 33, thereby cooling and lubricating the coarse grinding wheel 32 and the polishing wheel 33 during grinding or polishing, so as to improve the service life of the coarse grinding wheel 32 and the polishing wheel 33 and the grinding effect.
[0040] The working principle of the edge grinding and flexible polishing mechanism of the glass processing center grinding head provided in this embodiment of the invention is as follows:
[0041] During operation, the grinding wheel of the grinding head rotates 360 degrees with the hollow rotating platform and then returns to its original position. When rough grinding of the workpiece is required, the first cylinder 71 operates, and its extension rod extends to push the clamp 41 towards the direction of the second cylinder 72. Simultaneously, it drives the spindle 42, the second motor 43, and the grinding head assembly 3 to move together. When the clamp 41 is stopped by the limit screw 75, the movement stops. The first cylinder 71 and the limit screw 75 work together to fix the clamp 41. Then, the suspension seat 1 is moved to bring the rough grinding wheel 32 closer to the side of the workpiece. The second motor 43 then drives the rough grinding wheel 32 to rotate and grind the side of the workpiece. After rough grinding is completed, the lifting mechanism 2 drives the mounting seat 5 to rise, aligning the polishing wheel 33 with the side of the workpiece. At the same time, the extension rod of the first cylinder 71 retracts, and the extension rod of the second cylinder 72 extends, pushing the clamp 41 towards the direction of the first cylinder 71. There is no limiting screw 75 on one side of 71, and when the second cylinder 72 is working, the clamp 41 is not connected or abutting against other parts on the side near the first cylinder 71, so that the clamp 41 is in an active state. When the second cylinder 72 pushes the clamp 41 to move, it drives the polishing wheel 33 to press against the side of the workpiece and maintain a certain pressure. The polishing wheel 33 will wear continuously during the operation. Under the action of the control system and the second cylinder 72, the polishing wheel 33 and the side of the glass will always keep in close contact for polishing and maintain a certain pressure. When polishing different sides, the first motor 61 drives the guide rail seat 62 to rotate, so that the extension rod of the second cylinder 72 always faces the processing surface, thereby ensuring that the second cylinder 72 presses against the polishing wheel 33 and keeps it in contact with the processing surface, so that no edge is missed and the polishing is stable.
[0042] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
