Description

Technical Field

[0001] The utility model relates to the technical field of glass surface grinding, and specifically, to a tooling for grinding the glass surface. Background Technique

[0002] Glass is an inorganic non-metallic material, generally made of a variety of inorganic minerals as the main raw materials, and a small amount of auxiliary raw materials are added additionally. Its main components are silicon dioxide and other oxides. Glass products can be seen everywhere in our daily life and are widely used in fields such as architecture, daily use, art, medical treatment, chemistry, electronics, instrumentation, nuclear engineering, etc. Glass needs to go through the steps of grinding and polishing during the production process.

[0003] In the production of grinding the surface finish of glass, there are still many manual grinding processes. When workers hold the grinding tool and move it back and forth to grind the glass surface, due to the weight of the tool itself, it is difficult for workers to hold the grinding tool stably and grind the glass surface with the same force, resulting in uneven grinding of the glass surface. At the same time, the labor intensity of workers is also relatively large. Glass also needs to ensure good stability during the grinding process to avoid affecting the final grinding quality. In view of this, we propose a tooling for grinding the glass surface. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1-5 As shown, one of the purposes of this embodiment is to provide a tooling for grinding the surface of glass, including a processing table 1. A pushing cylinder 2 is fixedly connected to the center of the top of the processing table 1. The upper end of the piston rod of the pushing cylinder 2 is fixedly connected to a tray 3. A linear guide rail 5 is fixedly connected to a position near the top on one side of the processing table 1. A first sliding table 6 is slidably arranged on the upper side of the linear guide rail 5. A grinding motor 8 is arranged on the upper side of the first sliding table 6. A grinding disc 9 is coaxially and fixedly connected to the output shaft of the grinding motor 8. The grinding disc 9 is located above the tray 3. A position adjusting mechanism 7 is arranged between the grinding motor 8 and the first sliding table 6. The position adjusting mechanism 7 is used to adjust the position of the grinding motor 8 on the upper side of the first sliding table 6. The structure of the position adjusting mechanism 7 is refined as follows. Refer to Figure 1, the position adjustment mechanism 7 includes a second slide table 71 slidably disposed on the upper side of the first slide table 6. A second lead screw 72 is rotatably disposed on the first slide table 6. The second lead screw 72 is threadedly connected to the second slide table 71. One end of the second lead screw 72 away from the tray 3 is fixedly connected to a first handwheel. The operator rotates the first handwheel to drive the second lead screw 72 to rotate. Through the threaded connection between the second lead screw 72 and the second slide table 71, the rotation of the second lead screw 72 drives the second slide table 71 to horizontally move away from or close to the tray 3. At the same time, a third slide table 73 is slidably disposed on one side of the second slide table 71. A third lead screw 74 is rotatably disposed on the second slide table 71. The third lead screw 74 is threadedly connected to the third slide table 73. The upper end of the third lead screw 74 is fixedly connected to a second handwheel. The operator rotates the second handwheel to drive the third lead screw 74 to rotate. Through the threaded connection between the third lead screw 74 and the third slide table 73, the rotation of the third lead screw 74 drives the third slide table 73 to move in the vertical direction. The grinding motor 8 is fixedly disposed on the side of the third slide table 73 away from the second slide table 71. When the first handwheel rotates, the grinding motor 8 moves horizontally closer to or away from the tray 3. When the second handwheel rotates, the grinding motor 8 moves vertically closer to or away from the tray 3.

[0033] To improve the stability of glass grinding, a plurality of suction cups 31 are fixedly connected to the tray 3. The plurality of suction cups 31 are used to adsorb the glass. After placing the glass to be ground on the plurality of suction cups 31, the lower side of the glass is adsorbed by the suction cups 31 to prevent the glass from moving horizontally, achieving the positioning of the glass position. At the same time, a plurality of fixed brackets 4 are fixedly connected in a horizontal array on the upper surface of the processing table 1. The fixed brackets 4 are fixedly disposed between the tray 3 and the linear guide 5. A plurality of movable brackets 41 are slidably disposed in a horizontal array on the upper side of the processing table 1. The movable brackets 41 and the fixed brackets 4 are respectively disposed on opposite sides of the tray 3. Clamping brackets 42 are disposed on the other two sides of the tray 3. The fixed brackets 4, the movable brackets 41 and the clamping brackets 42 are all L-shaped structures. A placement groove is opened on one side of the tops of the fixed brackets 4, the movable brackets 41 and the clamping brackets 42 close to the tray 3. After adsorbing and fixing the glass on the upper side of the plurality of suction cups 31 and positioning the glass, the piston rod of the push cylinder 2 contracts to drive the tray 3 and the glass to move vertically downward until the lower surface of the glass contacts the bottom surface inside the plurality of placement grooves, and the four side surfaces of the glass contact the side surfaces inside the plurality of placement grooves, so that the fixed brackets 4, the movable brackets 41 and the clamping brackets 42 jointly limit the vertical and horizontal movement of the glass, improving the stability of the glass during grinding, and thus improving the quality of the glass ground by the worker.

[0034] When grinding glass of different sizes, after the tray 3 drives the glass to move downward, the glass cannot contact the placement grooves on all the fixed brackets 4, movable brackets 41 and clamping brackets 42, resulting in a decrease in the stability of the glass during grinding. To solve this problem, a displacement mechanism 43 is provided on the lower side of several movable brackets 41. The displacement mechanism 43 is used to drive several movable brackets 41 to approach or move away from the fixed bracket 4. By adjusting the distance between the movable bracket 41 and the fixed bracket 4, the movable bracket 41 and the fixed bracket 4 can support and limit glass of different widths. At the same time, a centering mechanism 45 is provided on the lower side of the two clamping brackets 42. The centering mechanism 45 is used to drive the two clamping brackets 42 to approach or move away from each other, so as to adjust the distance between the two clamping brackets 42, so that the two clamping brackets 42 can support and limit glass of different lengths. Furthermore, when the device grinds glass of different sizes, all the fixed brackets 4, movable brackets 41 and clamping brackets 42 can support the glass, thereby ensuring that glass plates of different sizes have high stability during grinding.

[0035] The structure of the displacement mechanism 43 is refined as follows. Refer to Figure 2 , the displacement mechanism 43 includes a first lead screw 432 rotatably arranged on the lower side of the processing table 1. One end of the first lead screw 432 is fixedly connected with a first knob. The knob is located on the side of the linear guide 5 away from the processing table 1. An extension frame 431 is threadedly connected to the first lead screw 432. A plurality of first movable grooves 11 are transversely arrayed on the upper side of the processing table 1. The first movable grooves 11 are correspondingly arranged with the movable brackets 41. The upper end of the extension frame 431 passes through the first movable grooves 11 and is fixedly arranged on the lower surfaces of several movable brackets 41. The extension frame 431 is slidably arranged inside the first movable grooves 11. When a worker holds the first knob and rotates the first lead screw 432, due to the threaded connection between the first lead screw 432 and the extension frame 431, the extension frame 431 slides along the inner walls of several first movable grooves 11. The sliding extension frame 431 drives several movable brackets 41 to horizontally move synchronously in the direction away from or close to the fixed bracket 4, adjusting the distance between the movable bracket 41 and the fixed bracket 4, so that the movable bracket 41 and the fixed bracket 4 can support and limit glass of different widths.

[0036] The structure of the centering mechanism 45 is refined as follows. Refer to Figure 2 and Figure 4, two second movable grooves 12 are formed in the upper side of the processing table 1, and the positions of the second movable grooves 12 correspond to those of the clamping brackets 42. A bottom block 451 is fixedly connected to the lower surface of the clamping bracket 42. The bottom block 451 is of an inverted T-shaped structure. The upper end of the bottom block 451 is slidably arranged inside the corresponding second movable groove 12. Rack bars 452 are fixedly connected to the sides of the two bottom blocks 451 close to each other. The top surface inside the processing table 1 is rotatably connected with a linkage shaft 453. A linkage gear 454 is coaxially and fixedly connected to the side wall of the linkage shaft 453. The two rack bars 452 are respectively meshed with the two sides of the linkage gear 454. A worm gear 455 is fixedly connected to the lower end of the linkage shaft 453. A worm 456 is rotatably arranged on the lower side between the linear guide rail 5 and the processing table 1. The worm 456 is meshed with the worm gear 455.

[0037] Meanwhile, a through groove is formed in the worm 456. The position near the middle section of the first lead screw 432 is rotatably arranged inside the through groove. The through groove plays a guiding role for the first lead screw 432, improves the stability of the first lead screw 432 during rotation, ensures the stable threaded connection between the first lead screw 432 and the extension bracket 431, and the first knob is arranged outside one end of the worm 456 far from the worm gear 455. Meanwhile, a second knob is fixedly connected to the side wall of the worm 456 near the first knob. When a worker holds the second knob and twists the worm 456, through the meshing transmission between the worm 456 and the worm gear 455, the worm gear 455 drives the linkage shaft 453 to rotate, and the linkage shaft 453 drives the linkage gear 454 to rotate synchronously. Through the meshing transmission between the two rack bars 452 and the linkage gear 454, the two rack bars 452 drive the corresponding bottom blocks 451 to approach or move away from each other along the inner walls of the second movable grooves 12. The moving bottom blocks 451 drive the corresponding clamping brackets 42 to move horizontally synchronously. In this way, the distance between the two clamping brackets 42 is adjusted so that the two clamping brackets 42 can support and limit glasses of different lengths.

[0038] The first knob and the second knob are arranged on the side close to the linear guide rail 5. The worker rotates the first knob and the second knob successively according to the size of the glass to adjust the distance between the movable bracket 41 and the fixed bracket 4 and the distance between the two clamping brackets 42, so that all the fixed brackets 4, movable brackets 41 and clamping brackets 42 can support the glass.

[0039] Meanwhile, the first knob and the second knob are arranged on the side close to the linear guide rail 5, which also facilitates the worker to control the position of the grinding motor 8.

[0040] The worker pre-sets a number of mutually contacting grinding paths on the glass. The number of grinding paths completely covers the upper surface of the glass. The width of the grinding path is the same as the thickness of the grinding disc 9, and all the grinding paths are parallel to the side of the glass close to the linear guide 5. When grinding the glass, the worker first rotates the first handwheel to horizontally move the grinding motor 8 and the grinding disc 9 away from the linear guide 5 until the grinding disc 9 is moved directly above the predetermined grinding path on the upper surface of the glass. This predetermined grinding path is located on the side of the upper surface of the glass closest to the linear guide 5. Then, the first slide 6 is horizontally moved along the linear guide 5 to move the grinding disc 9 directly above one end of the predetermined grinding path on the glass plate. Then, the worker rotates the second handwheel to vertically move the grinding motor 8 and the grinding disc 9 downward until the grinding disc 9 contacts the upper surface of the glass. Immediately afterwards, the grinding motor 8 is started so that its output shaft drives the grinding disc 9 to rotate at high speed. The rotating grinding disc 9 grinds the glass in contact with it. The worker then slowly pushes the first slide 6 along the linear guide 5 to make the grinding disc 9 travel along the predetermined grinding path on the glass towards the other end until the grinding disc 9 completely grinds the glass located on the predetermined grinding path. After the glass on one path is ground, the worker rotates the first handwheel again to move the grinding disc 9 further away from the linear guide 5 until the grinding disc 9 moves to the end point of the next grinding path on the glass, and the glass located on this grinding path is ground in the same way. By controlling the grinding of the glass on the grinding path by the grinding disc 9, the situation of the grinding route deviation does not occur during the grinding process of the grinding disc 9, so that the upper surface of the glass is comprehensively and evenly ground by the grinding disc 9, eliminating the situation of the worker holding the grinding tool to grind the glass, and reducing the labor intensity of the worker.
