Description

Technical Field

[0001] This utility model is a glass grinding machine with quick tool switching, belonging to the field of glass processing technology. Background Technology

[0002] Glass grinding machines are core equipment in glass deep processing, mainly used for deburring edges, surface frosting (reducing light transmittance), and grinding irregularly shaped edges of architectural glass (curtain walls, doors and windows), furniture glass (coffee tables, cabinet doors), and electronic glass (display screen covers). They achieve cutting and grinding by having high-speed rotating grinding wheels (such as 80-grit coarse grinding wheels and 200-grit fine grinding wheels) contact the glass surface. Commonly known glass grinding machines typically use a motor directly driven or a belt / gear driven spindle. The grinding wheels are fixed to the spindle in the following ways: Threaded locking type: The inner hole of the tool has threads, which are directly screwed onto the threads at the end of the spindle. This is the most common but least efficient method. Flange clamping type: The tool is clamped in the middle by two flanges, and then locked from the tail of the spindle with nuts.

[0003] However, both tightening threads and loosening nuts require the use of specialized wrenches, which is cumbersome, time-consuming, and labor-intensive. Changing a tool often takes several minutes. For small-batch, multi-variety orders, frequent tool changes severely restrict production efficiency. There is an urgent need for a glass grinding machine with quick tool switching to solve the above problems. Utility Model Content

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a glass grinding machine with rapid tool switching, including a processing table 1, a tool shaft 13, and a grinding wheel tool ring 16. Multiple electric lifting rods 3 are longitudinally mounted on the upper end of the processing table 1. The movable ends of the multiple electric lifting rods 3 are fixed to a glass carrier plate 4 via flanges and bolts. Mounting frames 5 are longitudinally fixed on both the left and right sides of the upper end of the glass carrier plate 4. Electric push rods 6 are installed through the middle of the upper ends of the two mounting frames 5. A hydraulic rod 8 is installed on the lower front side of the processing table 1. The movable end of the hydraulic rod 8 is connected to a connecting plate 9. A servo motor 10 is installed on the upper front side of the connecting plate 9. The shaft end of the servo motor 10 passes through the connecting plate 9 and is connected to a hexagonal insert rod 11. A vertical plate is fixed on the rear upper side of the processing table 1, and a ball bearing is embedded in the vertical plate. The front end of the ball bearing is connected to the tool shaft 13. Multiple arc-shaped fixing blocks 14 are fixed at equal angles on the annular side of the tool shaft 13. Multiple anti-detachment grooves 15 are provided on the side surface. Two grinding wheel cutter rings 16 are provided, and a grinding wheel cutter 17 is clamped between the two grinding wheel cutter rings 16. The two grinding wheel cutter rings 16 are slidably sleeved on the outside of multiple arc-shaped fixing blocks 14. Multiple arc-shaped guide shells 18 are fixed at equal angles on the inner side of the two grinding wheel cutter rings 16. The multiple arc-shaped guide shells 18 are slidably inserted into the gaps between multiple adjacent arc-shaped fixing blocks 14. Anti-slip knobs 19 are installed on the upper end of the multiple arc-shaped guide shells 18. Bidirectional screws 22 are installed inside the multiple arc-shaped guide shells 18 through bearings. Metal inner screw cylinders 23 are threaded on the left and right ends of the multiple bidirectional screws 22. Anti-detachment metal rods 24 are installed on the lower end of the multiple metal inner screw cylinders 23. This design solves the problem that when using threaded locking or flange pressure plate in known glass grinding machines, a special wrench is required, which is cumbersome, time-consuming and labor-intensive, and affects production efficiency.

[0020] In the first embodiment of this utility model: a PLC control panel 2 is installed at the front end of the processing table 1. The PLC control panel 2, multiple electric lifting rods 3, two electric push rods 6, hydraulic rods 8, and servo motors 10 are connected by wires. The PLC control panel 2 can be connected to the multiple electric lifting rods 3, two electric push rods 6, hydraulic rods 8, and servo motors 10 via wires to achieve centralized control of each actuator. Since this is an existing mature device, the control principle will not be described in detail. Push plates 7 are installed at the movable ends of the two electric push rods 6. The added push plates 7 are used to apply a pushing force to the glass during processing to prevent the glass from shifting.

[0021] A hexagonal slot 12 is provided at the front end of the tool shaft 13. A hexagonal insert 11 is inserted into the hexagonal slot 12. The hexagonal insert 11 at the end of the servo motor 10 shaft can be precisely inserted into the hexagonal slot 12 to achieve reliable power transmission. Multiple anti-slip knobs 19 are each equipped with a first bevel gear 20 at their lower end. Multiple bidirectional screws 22 are each equipped with a second bevel gear 21 in the middle of their outer surface. The multiple second bevel gears 21 mesh with the multiple first bevel gears 20 respectively. When the added second bevel gears 21 mesh with the first bevel gears 20, rotating the anti-slip knob 19 can drive the bidirectional screws 22 to rotate. Multiple anti-detachment metal rods 24 pass through the left and right ends of multiple arc-shaped guide shells 18 and are inserted into the corresponding anti-detachment grooves 15. By adding multiple anti-detachment metal rods 24, passing through the left and right ends of the arc-shaped guide shells 18 and being inserted into the corresponding anti-detachment grooves 15, the grinding wheel tool ring 16 is firmly locked in the axial direction, preventing the tool from loosening during high-speed rotation.

[0022] As a second embodiment of this utility model: When it is necessary to replace the grinding wheel tool 17, the operator first controls the movable end of the hydraulic rod 8 to extend forward through the PLC control panel 2, driving the connecting plate 9 and the servo motor 10 to move forward, so that the hexagonal insert 11 exits from the hexagonal slot 12 at the front end of the tool shaft 13, disconnecting the power transmission. Subsequently, the operator rotates each anti-slip knob 19, and through the meshing transmission of the first bevel gear 20 and the second bevel gear 21, drives the bidirectional screw 22 to rotate, so that the metal inner screw 23 moves towards the center along the thread, driving the anti-detachment metal rod 24 to exit from the anti-detachment groove 15. At this time, the two grinding wheel tool rings 16 can slide forward along the arc-shaped fixing block 14 and be removed. After replacing the required grinding wheel tool 17, the grinding wheel tool rings 16 are re-sleeved on the outside of the arc-shaped fixing block 14, and the anti-slip knobs 19 are rotated in the opposite direction to make the anti-detachment metal rod 24 re-clamp into the anti-detachment groove 15, completing the quick clamping of the tool. Finally, the hydraulic rod 8 drives the connecting plate 9 and the servo motor 10 to move backward, so that the hexagonal insert 11 can be re-inserted into the hexagonal slot 12, thus restoring the processing state. Note: Glass frosting is an existing mature process, and this utility model will not elaborate on it.
