Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment, and in particular to an edge grinding machine for high-strength insulating glass. Background Technology

[0002] Insulating glass is widely used in the construction industry due to its excellent heat and sound insulation properties, and the edging process is a crucial step in its production. Traditional edging machines, when processing high-strength insulating glass, often require complex adjustments for glass of varying thicknesses or sizes, resulting in low processing efficiency. Furthermore, existing equipment, due to insufficient precision in the fit between the clamping mechanism and the edging components, is prone to causing micro-cracks or unevenness at the glass edges, affecting product quality and strength. Simultaneously, high-strength insulating glass demands higher precision in edge treatment, which traditional equipment struggles to meet, increasing the risk of subsequent repairs or scrapping. Moreover, with the diversification of glass specifications, the versatility and adaptability of existing edging machines are insufficient, further limiting production flexibility and efficiency improvements.

[0019] This utility model relates to a grinding machine for high-strength insulating glass, the structure of which is as follows: Figures 1 to 3 As shown. The base plate 1 is the basic component of the entire device. A slide rail is provided on the upper surface of the base plate 1, and two symmetrically distributed sliders 3 are mounted on the slide rail. The sliders 3 are connected to a bidirectional screw 2 via threads. The two ends of the bidirectional screw 2 are respectively provided with threaded sections in opposite directions. One end of the bidirectional screw 2 extends to the outside of the base plate 1 and is equipped with a handwheel. When the operator rotates the handwheel, the bidirectional screw 2 rotates. Because the threads at both ends of the bidirectional screw 2 rotate in opposite directions, the two sliders 3 will move synchronously along the slide rail in opposite directions. A clamping assembly is fixedly connected to the upper surface of the sliders 3. The clamping assembly includes a clamping plate 4 and an elastic pressure bar 5. The clamping plate 4 is arranged perpendicular to the sliding direction of the sliders 3. The elastic pressure bar 5 is movably connected to the inner wall of the clamping plate 4 via a spring hinge. A limit groove is provided on the top of the clamping plate 4, and a limit block 6 is embedded in the limit groove. The lower surface of the limit block 6 contacts the upper surface of the elastic pressure bar 5 to limit the swing range of the elastic pressure bar 5. The inner surface of the elastic pressure strip 5 is bonded with a flexible pad made of silicone. The clamping assembly also includes a positioning pin 7, which penetrates vertically through the top of the clamping plate 4 and is threadedly connected to the clamping plate 4. The bottom of the positioning pin 7 is provided with a tapered end, the tip of which faces the upper surface of the elastic pressure strip 5. The top of the positioning pin 7 is provided with a hexagonal groove.

[0020] A mounting base 8 is located in the middle of the base plate 1. A drive module is mounted on the mounting base 8. The drive module includes a motor 9 and a transmission shaft 10. One end of the transmission shaft 10 is fixedly connected to the output shaft of the motor 9 via a coupling, and the other end is rotatably connected to the mounting base 8 via a bearing. A gear disk 11 is located in the middle of the transmission shaft 10. A rack 12 meshes with the outer periphery of the gear disk 11. The rack 12 is horizontally arranged and fixedly connected to the grinding unit. The grinding unit includes a grinding head assembly and a lifting assembly. The lifting assembly includes a lead screw 14 and guide posts 15. Both ends of the lead screw 14 are fixedly connected to the rack 12 via bearing seats, and one end of the lead screw 14 extends to the outside of the rack 12 and is equipped with an adjustment knob. The guide posts 15 are arranged parallel to the lead screw 14 and penetrate the outer shell of the grinding head assembly. There are two guide posts 15, symmetrically distributed on both sides of the lead screw 14. The grinding head assembly includes a grinding wheel 13 and a protective cover 16. The grinding wheel 13 is fixedly connected to the nut seat of the lead screw 14 via a rotating shaft. A driven gear is installed at one end of the rotating shaft, and the driven gear meshes with the gear disc 11. The protective cover 16 surrounds the grinding wheel 13, and its inner side wall is provided with a dust suction hole 17, which is connected to an external dust suction device through a pipe. The outer circumference of the grinding wheel 13 is coated with a diamond coating with a thickness of 0.5 mm. The diameter of the grinding wheel 13 is 100 mm and its width is 20 mm. Limiting blocks are provided at both ends of the rack 12, and the limiting blocks are fixedly connected to the rack 12 by bolts.

[0021] The bottom of the base plate 1 is equipped with a shock-absorbing pad made of rubber, 10 mm thick, with anti-slip texture on its lower surface. Auxiliary support frames 18 are provided on both sides of the base plate 1, and are movably connected to the base plate 1 via hinges. Rollers 19 are provided on the top of the auxiliary support frames 18, and the outer circumference of the rollers 19 is covered with a rubber layer. A scale is provided on the housing of the grinding head assembly, arranged along the axial direction of the lead screw 14, with a minimum graduation of 0.1 mm.

[0022] In practical use, the high-strength insulating glass to be processed is first placed between the clamping components. Rotating the handwheel causes the bidirectional screw 2 to rotate, driving the two sliders 3 to move closer together along the slide rail, thus clamping the glass with the clamping plate 4. During clamping, the elastic pressure strip 5 adheres to the glass surface through the elastic action of the spring hinge, and the flexible padding layer prevents damage to the glass surface. When further enhancing clamping stability is needed, the positioning pin 7 can be tightened with a tool, causing the tapered end of the positioning pin 7 to apply pressure to the elastic pressure strip 5. After clamping is complete, the motor 9 is started. The output shaft of the motor 9 drives the transmission shaft 10 to rotate through the coupling. The gear disk 11 on the transmission shaft 10 rotates accordingly, meshing with the rack 12, thereby driving the rack 12 to move horizontally. The movement of the rack 12 causes the entire edging unit to move horizontally. Simultaneously, by adjusting the knob, the lead screw 14 is rotated, and the nut seat of the lead screw 14 drives the grinding wheel 13 to rise and fall vertically. The guide column 15 ensures the stability of the rising and falling process of the grinding wheel 13. The grinding wheel 13 rotates by meshing with the gear disk 11 via a driven gear on the rotating shaft. The diamond coating on the grinding wheel 13 efficiently grinds the glass edge. The dust extraction hole 17 inside the protective cover 16 is connected to an external dust extraction device through a pipe, effectively reducing dust diffusion. During the edge grinding process, the torque sensor on the drive shaft 10 monitors the load in real time. If the load exceeds the preset value, the controller automatically cuts off the power to the motor 9 to prevent overload damage to the equipment. After processing, the positioning pin 7 is loosened, and the slider 3 is separated by rotating the handwheel in the opposite direction, allowing the processed glass to be removed. The auxiliary support frame 18 provides support during glass loading and unloading, and the rubber layer of the roller 19 reduces the friction between the glass and the support frame, reducing the burden of manual operation.

[0023] To enable those skilled in the art to fully understand and implement this utility model, the following further supplements the explanation of the operating principle and implementation steps of this utility model in conjunction with specific application scenarios.

[0024] First, in the actual operation of high-strength insulating glass edge grinding, the glass to be processed needs to be placed between the clamping components. At this time, by rotating the handwheel of the bidirectional screw 2, the two sliders 3 move synchronously in opposite directions along the slide rail, thereby driving the clamping plate 4 to gradually approach the sides of the glass. During this process, the elastic pressure strip 5 automatically fits against the glass surface through the action of the spring hinge, and the flexible padding layer bonded to its inner side can effectively prevent the glass surface from being damaged due to direct contact. After the glass is initially clamped, the positioning pin 7 can be tightened with a tool, so that the conical end of the positioning pin 7 applies additional pressure to the elastic pressure strip 5, further enhancing the clamping stability. This clamping method not only adapts to glass of different thicknesses, but also ensures the fixation effect of the glass during processing, avoiding edge cracks or unevenness caused by unstable clamping.

[0025] Subsequently, motor 9 is started, and drive shaft 10 is connected to the output shaft of motor 9 via a coupling and rotates accordingly, driving gear disk 11 to rotate. Gear disk 11 meshes with rack 12, causing rack 12 to move horizontally, thereby driving the entire edge grinding unit to move horizontally. At the same time, the grinding wheel 13 can be vertically raised and lowered by adjusting the adjustment knob on lead screw 14. The nut seat of lead screw 14 is fixedly connected to the rotating shaft of grinding wheel 13, and guide post 15 passes through the housing of grinding head assembly to ensure that grinding wheel 13 remains stable during raising and lowering. This design, through the cooperation of gear disk 11, rack 12, and lead screw 14, achieves precise control of grinding wheel 13 in both horizontal and vertical directions, meeting the high-precision requirements of edge processing for high-strength insulating glass.

[0026] During the edge grinding process, the outer circumference of the grinding wheel 13 is coated with a diamond layer with a thickness of 0.5 mm, enabling efficient grinding of the glass edges. A protective cover 16 surrounds the grinding wheel 13, and its inner wall has dust extraction holes 17 connected to an external dust extraction device via pipes, effectively reducing dust dispersion and improving the working environment. Simultaneously, a torque sensor mounted on the drive shaft 10 monitors the load in real time. When the load exceeds a preset value, the controller automatically cuts off the power to the motor 9 to prevent damage to the equipment due to overload. This design significantly improves the safety and lifespan of the equipment.

[0027] After processing, the double-ended screw 2 is reversed by rotating the handwheel in the opposite direction, causing the two sliders 3 to separate along the slide rail. The processed glass can then be removed after releasing the locating pin 7. During this process, the auxiliary support frame 18 unfolds via a hinge, and the rollers 19 on its top provide additional support, reducing friction during glass loading and unloading and lowering the burden on manual operators. The rubber layer on the rollers 19 further enhances the stability of the support, preventing the glass from sliding or colliding during loading and unloading.

[0028] Furthermore, the scale on the grinding head assembly housing is arranged along the axial direction of the lead screw 14, with a minimum scale of 0.1 mm, facilitating precise adjustment of the grinding wheel 13's lifting height by the operator to meet the processing requirements of glass of different specifications. The shock-absorbing pad at the bottom of the base plate 1 is made of rubber with a thickness of 10 mm and has anti-slip texture on its lower surface, effectively absorbing vibrations generated during equipment operation and improving overall stability. The limit blocks at both ends of the rack 12 are fixed with bolts, restricting the movement range of the grinding unit and preventing the grinding wheel 13 from exceeding the working area, thereby ensuring the safety and reliability of equipment operation.

[0029] In summary, this invention, through its structure and operating principle, solves the problems of complex adjustment, insufficient clamping precision, and poor versatility inherent in traditional edging machines when processing high-strength insulating glass. Its optimized clamping structure, efficient edging method, and precise adjustment mechanism significantly improve processing efficiency and product quality, while reducing the risk of subsequent repairs or scrapping.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
