Description

Technical Field

[0001] This utility model relates to a chamfering device for square glass. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary materials. It is widely used in buildings for wind insulation and light transmission. Currently, when processing square glass, most methods involve beveling the edges of the glass using a beveling device. When using this device, the square glass is first fixed by a positioning mechanism, and then a rotating grinding block is used to bevele the four corners of the glass sequentially. The grinding process at the four corners is discontinuous, and deviations in grinding depth and shape are prone to occur, resulting in significant errors in the beveled square glass. Utility Model Content

[0003] To address the shortcomings mentioned above, this utility model provides a chamfering device for square glass.

[0004] To achieve the above objectives, this utility model provides a chamfering device for square glass, including a base. The upper part of the base is provided with a vacuum suction cup for adsorbing the square glass. Grinding blocks are symmetrically arranged on both sides of the base. The upper part of the grinding blocks is hinged to the end of the crossbeam via a vertical rod. The middle part of the crossbeam is fixed to the lower end of the positioning bushing. The positioning bushing is vertically arranged and rotated by a gear mechanism. A guide rod is slidably provided inside the positioning bushing. The upper end of the guide rod is connected to a cylinder. The lower end of the guide rod extends out of the positioning bushing and is rotatably mounted with a movable ring. The movable ring is hinged to the vertical rod via a connecting rod.

[0005] After the square glass is positioned on the base, the positioning bushing drives the grinding block to rotate synchronously through the crossbeam, and the guide rod drives the grinding block to approach the corner of the square glass for grinding through the connecting rod.

[0006] As a further improvement of this utility model, the base is square, and limiting blocks are symmetrically installed at the edge of the base, and the limiting blocks respectively position the four sides of the square glass.

[0007] As a further improvement of this utility model, the positioning bushing is rotatably mounted in the middle of the positioning seat through a bearing component, and the gear mechanism includes a driven gear fitted on the upper part of the positioning bushing and a driving gear meshing with the driven gear. The driving gear is mounted on the end of the main shaft of the drive motor, and the drive motor is fixed on the upper part of the positioning seat.

[0008] As a further improvement of this utility model, an upper fixed seat is provided above the positioning seat, the positioning seat is fixedly connected to the upper fixed seat through a support rod, and the cylinder is installed on the upper part of the upper fixed seat.

[0009] As a further improvement of this utility model, a grinding groove is machined on the side of the grinding block facing the center of the crossbeam.

[0010] As a further improvement of this utility model, an ear plate is fixedly provided on the outer circumferential surface of the movable ring, and one end of the connecting rod is hinged to the ear plate.

[0011] The beneficial effects of this utility model are as follows:

Detailed Implementation

[0018] like Figure 1 As shown, the chamfering device for square glass of this utility model includes a base 1, a vacuum suction cup 2 on the upper part of the base 1 for adsorbing the square glass 4, the base 1 is square, and limiting blocks 3 are symmetrically installed at the edges of the base 1 (see...). Figure 2The limiting blocks 3 position the four edges of the square glass 4 respectively. The grinding blocks 5 are symmetrically arranged on both sides of the base 1. The upper part of the grinding blocks 5 is hinged to the end of the crossbeam 8 through the upright rod 6. The grinding block 5 has a grinding groove 51 machined on the side facing the center of the crossbeam 8. The middle part of the crossbeam 8 is fixed to the lower end of the positioning bushing 10. The positioning bushing 10 is set vertically and rotated by the gear mechanism. The guide rod 9 is slidably provided inside the positioning bushing 10. The upper end of the guide rod 9 is connected to the cylinder 15. The lower end of the guide rod 9 extends out of the positioning bushing 10 and is rotatably installed with a movable ring 19. The movable ring 19 is hinged to the upright rod 6 through the connecting rod 7. An ear plate 191 is fixed on the outer circumferential surface of the movable ring 19. One end of the connecting rod 7 is hinged to the ear plate 191. The positioning bushing 10 is rotatably mounted on the middle of the positioning seat 11 through the bearing 12. The gear mechanism includes a driven gear 13 fitted on the upper part of the positioning bushing 10 and a driving gear 17 meshing with the driven gear 13. The driving gear 17 is mounted on the end of the main shaft of the drive motor 18. The drive motor 18 is fixed on the upper part of the positioning seat 11. An upper fixed seat 14 is provided above the positioning seat 11. The positioning seat 11 is fixedly connected to the upper fixed seat 14 through the support rod 16. The cylinder 15 is mounted on the upper part of the upper fixed seat 14.

[0019] After the square glass 4 is positioned on the base 1, the positioning bushing 10 drives the grinding block 5 to rotate synchronously through the crossbeam 8, and the guide rod 9 drives the grinding block 5 to approach the corner of the square glass 4 for grinding through the connecting rod 7.

[0020] The device controls the depth of the grinding block through a linkage structure. The guide rod drives the grinding block to move closer to or away from the corner of the square glass through the linkage. The grinding block rotates with the crossbeam, which can grind the four corners of the square glass at the same time. The grinding efficiency is high, the depth of the grinding block is uniform and controllable, and the chamfering quality is guaranteed.

[0021] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0022] During operation, the grinding blades are initially in an open position, with the distance between them greater than the diagonal length of the square glass. The square glass is placed on the base, and the limiting blocks limit the four sides of the square glass to ensure that the center of the square glass matches the center of the upper crossbeam. Then, it is positioned by vacuum suction cup. The drive motor works, and the driven gear drives the positioning bushing to rotate with the drive gear. The crossbeam and grinding blocks located at the lower part of the positioning bushing rotate synchronously. Then, the guide rod is controlled by the cylinder to move down along the positioning bushing. The movable ring at the lower part of the guide rod pulls the upright rod to rotate towards the center of the crossbeam through the connecting rod. The grinding blocks at the lower part of the upright rod move closer to the edge of the square glass accordingly. When the distance between the two grinding blocks matches the diagonal length of the square glass, the grinding blocks contact the corners of the glass and grind them. The four corners of the glass are ground into chamfers in one go without the need for multiple positioning.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
