Description

Technical Field

[0001] This utility model relates to the technical field of edge grinding devices for tempered glass production, specifically an edge grinding device for tempered glass production with adjustable grinding angle. Background Technology

[0002] Tempered glass is widely used in building curtain walls, doors, and windows. In the automotive industry, it is a primary material for car windows. In electronic devices such as mobile phone screens and tablet displays, tempered glass is also frequently used to provide protection and excellent optical performance. With the continuous development of these industries, the requirements for the quantity and quality of tempered glass are increasing daily.

[0003] According to a published application (CN216577062U) of a tempered glass edging device, the aforementioned application describes a grinding device where a servo motor drives a rotating plate, which in turn drives a convex column to rotate an adjusting rod. The rotating rod causes a slider to slide within a movable groove and rotate on an outer plate, simultaneously driving a grinding motor to rotate, which in turn drives a grinding disc to rotate, adjusting the angle of the grinding disc. A servo motor drives a bidirectional lead screw to rotate, causing lead screw pairs one and two to move closer together, thus moving the grinding disc closer to the tempered glass for grinding both sides, resulting in high grinding efficiency. However, existing tempered glass edging devices have different requirements for the shape and angle of the tempered glass edges in different application scenarios. Various edge shapes, such as bevels and curved edges, may be required, necessitating adjustment of the grinding disc angle. However, during the edging process, the high-speed rotation of the grinding disc in contact with the glass edge generates cutting force that easily causes vibration, which is difficult to effectively suppress. Vibration of the glass can lead to a decrease in the precision of the grinding process, resulting in uneven edges, dimensional deviations, and other problems that severely affect the quality of the glass. Furthermore, the stress distribution of the adjusted grinding disc will become even more uneven. Thinner areas will experience greater stress concentration during use, thus increasing the risk of breakage when the grinding disc vibrates. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable grinding angle edge grinding device for tempered glass production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass edging device with adjustable grinding angle, comprising a grinding machine, a fixed frame fixedly mounted on the top of the grinding machine, a control motor fixedly mounted on the right side of the fixed frame, a reciprocating lead screw fixedly mounted on the output shaft surface of the control motor, the control motor being activated to drive the reciprocating lead screw to rotate, the reciprocating lead screw rotating to drive a movable block to slide on the surface of the fixed frame, thereby driving the grinding disc on the surface of the movable block to adjust left and right, the reciprocating lead screw being rotatably connected inside the fixed frame, the movable block being threadedly connected to the surface of the reciprocating lead screw, the movable block being slidably connected to the surface of the fixed frame, the surface of the movable block being provided with a protective component for protecting the worker during grinding and a movable component for adjusting the grinding angle, and the movable component comprising:

[0006] A fixed strip is fixedly installed on the surface of the movable block. A telescopic cylinder is fixedly installed on the top of the fixed strip. Activating the telescopic cylinder causes the movable strip to slide downwards on the surface of the fixed strip. When the movable strip slides downwards, it causes the first telescopic rod and the positioning plate to slide downwards. When the positioning plate slides downwards, it abuts against the top of the tempered glass for fixation. The movable strip is fixedly installed on the surface of the telescopic cylinder and is slidably connected to the surface of the fixed strip. A first telescopic rod is fixedly installed at the bottom of the movable strip, and a positioning plate is fixedly installed on the surface of the first telescopic rod.

[0007] Preferably, a fixing block is fixedly installed at the bottom of the movable strip, an angle ruler is fixedly installed on the surface of the fixing block, and a semi-turbine is fixedly installed at the bottom of the fixing block.

[0008] Preferably, an adjusting block is slidably connected to the bottom of the fixed block, and a worm gear is rotatably connected inside the adjusting block. The worm gear is rotated by manually turning the torsion block. When the worm gear rotates, it causes the top meshing half-worm gear to slide on the surface of the worm gear. When the half-worm gear slides, it causes the adjusting block to slide at the bottom of the fixed block. A torsion block is fixedly installed on the surface of the worm gear, and an angle needle is fixedly installed on the surface of the adjusting block. When the adjusting block slides, it swings in an arc angle. When the adjusting block is adjusted, it can cause the angle needle to slide on the surface of the angle ruler in the same direction as the movement of the adjusting block, thereby achieving the effect of accurate adjustment.

[0009] Preferably, a micro motor is fixedly installed at the bottom of the adjusting block, and a grinding disc is fixedly installed on the output shaft surface of the micro motor. A rotating shaft is connected to the surface of the torsion block via a belt drive. The rotating shaft is rotatably connected to the bottom of the adjusting block, and a sliding shaft is slidably connected to the surface of the rotating shaft. When the sliding shaft moves, it will drive the clamping ring to slide in the same direction as the sliding shaft, thereby restricting the grinding disc and fixing the shaking grinding disc through the clamping plate under the torsion spring. This improves the stability of the grinder and enhances the grinding quality of the object. One end of the sliding shaft is slidably connected to the bottom of the adjusting block, and the other end of the sliding shaft is fixedly installed with a clamping ring. A clamping plate is hinged to the inside of the clamping ring, and one end of the torsion spring is fixedly installed inside the clamping plate. The other end of the torsion spring is fixedly installed inside the clamping ring.

[0010] Preferably, the protective component includes: a second telescopic rod, which is fixedly installed on the outside of the movable strip. A connecting block is fixedly installed on the surface of the second telescopic rod. The downward sliding movable strip will also drive the connecting block to slide downward inside the grinder via the second telescopic rod. When the connecting block slides downward, it will drive the toothed plate to slide downward. A toothed plate is fixedly installed at the bottom of the connecting block. A movable shaft is rotatably connected inside the grinder. When the movable shaft rotates, it will drive the protective plate to rotate upward. When the protective plate rotates upward, it will protect both sides of the grinder, preventing tempered glass shards from the grinder from flying onto the workers and causing safety hazards. This improves the safety of using the grinder and increases the protection of the workers. The movable shaft passes through the grinder, and a gear is fixedly installed on the surface of the movable shaft. The gear meshes with the surface of the toothed plate. A protective plate is fixedly installed on the surface of the movable shaft.

[0011] Preferably, the surface of the fixed strip is provided with a groove, which can drive the movable strip to slide on the surface of the fixed strip. The outer side of the fixed strip is provided with a groove, which can improve the connection effect between the telescopic rod and the movable strip. The top of the grinder is provided with a square groove, which can drive the toothed plate to slide downward inside the grinder to drive the rotation of the gear.

[0012] Preferably, the cross-section of the fixing block is semi-circular.

[0013] Compared with the prior art, this utility model provides an adjustable grinding angle edge grinding device for tempered glass production, which has the following beneficial effects:

[0014] 1. This adjustable grinding angle tempered glass production edge grinding device can drive the rotating shaft to rotate via a belt through a torsion block set in the moving component. The rotation of the rotating shaft drives the clamping ring fixed on the surface of the sliding shaft to clamp and fix it on the surface of the grinding disc, which improves the stability of the grinding machine and enhances the grinding quality of objects.

[0015] 2. This adjustable grinding angle tempered glass production edge grinding device can drive the gear to rotate through a downward sliding toothed plate set in the protective component. When the gear rotates, it drives the protective plate to rotate through the movable shaft, thereby protecting both sides of the grinding machine and preventing tempered glass fragments from the grinding machine from flying onto the workers and causing safety hazards, thus increasing the protection of the workers.

[0022] like Figures 1-5As shown, this utility model provides a technical solution: an adjustable grinding angle tempered glass edging device, including a grinding machine 1, a fixed frame 2 fixedly mounted on the top of the grinding machine 1, a control motor 3 fixedly mounted on the right side of the fixed frame 2, and a reciprocating lead screw 4 fixedly mounted on the output shaft surface of the control motor 3. The control motor 3 is activated to drive the reciprocating lead screw 4 to rotate. When the reciprocating lead screw 4 rotates, it causes a movable block 5 to slide on the surface of the fixed frame 2, thereby causing the grinding disc 714 on the surface of the movable block 5 to adjust left and right. The reciprocating lead screw 4 is rotatably connected inside the fixed frame 2, and the surface of the reciprocating lead screw 4 is threaded... A movable block 5 is attached to the surface of the fixed frame 2. The surface of the movable block 5 is provided with a protective component 6 for protecting the worker during grinding and a movable component 7 for adjusting the grinding angle. The movable component 7 includes: a fixed bar 71, a telescopic cylinder 72, a movable bar 73, a telescopic rod 74, a positioning plate 75, a fixed block 76, an angle ruler 77, a semi-turbine 78, an adjusting block 79, a worm gear 710, a torsion block 711, an angle needle 712, a micro motor 713, a grinding disc 714, a rotating shaft 715, a sliding shaft 716, a clamping ring 717, a clamping plate 718, and a torsion spring 719.

[0023] A fixed strip 71 is fixedly installed on the surface of the movable block 5. A telescopic cylinder 72 is fixedly installed on the top of the fixed strip 71. Activating the telescopic cylinder 72 causes the movable strip 73 to slide downwards on the surface of the fixed strip 71. When the movable strip 73 slides downwards, it causes the telescopic rod 74 and the positioning plate 75 to slide downwards. When the positioning plate 75 slides downwards, it abuts against the top of the tempered glass for fixation. The movable strip 73 is fixedly installed on the surface of the telescopic cylinder 72 and slidably connected to the surface of the fixed strip 71. A telescopic rod 74 is fixedly installed at the bottom of the movable strip 73, and a positioning plate 75 is fixedly installed on the surface of the telescopic rod 74. A fixed block 76 is fixedly installed at the bottom of the movable strip 73. An angle gauge 77 is fixedly installed on the surface of the fixed block 76. A semi-worm gear 78 is fixedly installed at the bottom of the fixed block 76. An adjusting block 79 is slidably connected to the bottom of the fixed block 76. A worm gear 710 is rotatably connected inside the adjusting block 79. The worm gear 710 is rotated by manually turning the torsion block 711. When the worm gear 710 rotates, it will cause the semi-worm gear 78, which is engaged at the top, to slide on the surface of the worm gear 710. When the semi-worm gear 78 slides, it will cause the adjusting block 79 to slide at the bottom of the fixed block 76. The torsion block 711 is fixedly installed on the surface of the worm gear 710. The adjusting block 79 is fixedly installed on the surface of the fixed block 76. An angle pin 712 is fixedly installed on the surface of the adjusting block 79. When the adjusting block 79 slides, it swings in an arc angle. When the adjusting block 79 adjusts the angle, it can drive the angle pin 712 to slide on the surface of the angle ruler 77 in the same direction as the movement of the adjusting block 79, thereby achieving an accurate adjustment effect. A micro motor 713 is fixedly installed at the bottom of the adjusting block 79. A grinding disc 714 is fixedly installed on the surface of the output shaft of the micro motor 713. A rotating shaft 715 is connected to the surface of the torsion block 711 via a belt drive. The rotating shaft 715 is rotatably connected to the bottom of the adjusting block 79. A sliding shaft 716 is slidably connected to the surface of the rotating shaft 715. When the sliding shaft 716 moves... When in motion, the clamping ring 717 slides in the same direction as the sliding shaft 716, thereby restricting the grinding disc 714. The clamping plate 718 under the torsion spring 719 fixes the shaking grinding disc 714, improving the stability of the grinder 1 and enhancing the grinding quality of the object. One end of the sliding shaft 716 is slidably connected to the bottom of the adjusting block 79, and the other end of the sliding shaft 716 is fixedly installed with the clamping ring 717. The clamping plate 718 is hinged to the inside of the clamping ring 717. One end of the torsion spring 719 is fixedly installed on the inside of the clamping plate 718, and the other end of the torsion spring 719 is fixedly installed on the inside of the clamping ring 717.

[0024] Protective component 6 includes: a second telescopic rod 61, which is fixedly installed on the outside of the movable strip 73. A connecting block 62 is fixedly installed on the surface of the second telescopic rod 61. The downward sliding movable strip 73 will also drive the connecting block 62 to slide downward inside the grinder 1 through the second telescopic rod 61. When the connecting block 62 slides downward, it will drive the toothed plate 63 to slide downward. The toothed plate 63 is fixedly installed at the bottom of the connecting block 62. A movable shaft 64 is rotatably connected inside the grinder 1. When the movable shaft 64 rotates, it will drive the protective plate 66 to rotate upward. When the protective plate 66 rotates upward, it will protect both sides of the grinder 1 to prevent tempered glass shards from the grinder 1 from flying onto the workers and causing safety hazards. This improves the safety of using the grinder 1 and increases the protection of workers. The movable shaft 64 passes through the grinder 1, and a gear 65 is fixedly installed on the surface of the movable shaft 64. The gear 65 meshes with the surface of the toothed plate 63. A protective plate 66 is fixedly installed on the surface of the movable shaft 64. A sliding groove 7100 is opened on the surface of the fixed strip 71, which can drive the movable strip 73 to slide on the surface of the fixed strip 71. A groove 7101 is opened on the outer side of the fixed strip 71, which can improve the connection effect between the telescopic rod 61 and the movable strip 73. A square groove 10 is opened on the top of the grinder 1. The cross-section of the fixed block 76 is semi-arc, which can drive the toothed plate 63 to slide downward inside the grinder 1 to drive the rotation of the gear 65.

[0025] When the polishing machine 1 needs to polish tempered glass, the tempered glass can be placed on top of the polishing machine 1. The control motor 3 is activated to drive the reciprocating screw 4 to rotate. The rotation of the reciprocating screw 4 causes the movable block 5 to slide on the surface of the fixed frame 2, thereby adjusting the polishing disc 714 on the surface of the movable block 5 left and right. After adjustment, the telescopic cylinder 72 can be activated to drive the movable strip 73 to slide downwards on the surface of the fixed strip 71. When the movable strip 73 slides downwards, it causes the telescopic rod 74 and the positioning plate 75 to slide downwards. When the positioning plate 75 slides downwards, it will abut against the top of the tempered glass for fixation. During polishing, the micro motor 713 can be activated to drive the polishing disc 714 to rotate, thus polishing the tempered glass. When the angle of the polishing disc 714 needs to be adjusted, the torsion block 711 can be manually turned to drive the worm gear 710 to rotate. When 710 rotates, it drives the top-engaged semi-turbine 78 to rotate. When the semi-turbine 78 rotates, since the fixed block 76 is arc-shaped, the adjusting block 79 will swing in an arc angle when it slides. When the adjusting block 79 adjusts the angle, it can drive the angle needle 712 to slide on the surface of the angle ruler 77 in the same direction as the moving position of the adjusting block 79, thereby achieving the effect of accurate adjustment. When the torsion block 711 rotates, it will also drive the rotating shaft 715 to rotate through the belt. When the rotating shaft 715 rotates, it will drive the sliding shaft 716 to move closer to the surface of the grinding disc 714. When the sliding shaft 716 moves, it will drive the clamping ring 717 to slide in the same direction as the sliding shaft 716, thereby restricting the grinding disc 714 with the clamping ring 717. The clamping plate 718 under the torsion spring 719 fixes the shaking grinding disc 714, improving the stability of the grinding machine 1 and enhancing the grinding quality of the object.

[0026] When the grinder 1 is grinding, the downward sliding movable bar 73 will also drive the connecting block 62 to slide downward inside the grinder 1 via the telescopic rod 61. When the connecting block 62 slides downward, it will drive the toothed plate 63 to slide downward. When the toothed plate 63 slides downward, it will drive the gear 65 meshing on the surface of the toothed plate 63 to rotate. When the gear 65 rotates, it will drive the movable shaft 64 to rotate. When the movable shaft 64 rotates, it will drive the protective plate 66 to rotate upward. When the protective plate 66 rotates upward, it will protect both sides of the grinder 1, preventing the tempered glass shards from the grinder 1 from flying onto the workers and causing safety hazards. This improves the safety of using the grinder 1 and increases the protection of the workers.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
