DETAILED DESCRIPTION
[0022] like Figure 1 As shown, the glass outer circle grinding device described in the utility model comprises a base 1, a grinding knife 4 arranged on the left side of the base 1, and a side balancing mechanism 8 arranged on the right side of the base 1. A vacuum suction cup 2 is arranged on the upper part of the base 1 for adsorbing the glass 3. A groove 11 is processed at the center of the upper part of the base 1. The vacuum suction cup 2 is arranged in the groove 11. A ventilation groove is arranged on the side wall of the groove 11. The grinding knife 4 and the side balancing mechanism 8 are both installed on a turntable 7. The center of the upper part of the turntable 7 is connected to a driving shaft 9. The center of the turntable 7 corresponds to the center of the glass 3.
[0023] The grinding knife 4 is connected to the turntable 7 through the tool holder assembly 5. The tool holder assembly 5 and the turntable 7 are in a swing connection structure. The tool holder assembly 5 includes a vertical rod 51. The lower part of the vertical rod 51 is connected to the grinding knife 4. The upper part of the vertical rod 51 passes through the U-shaped groove 71 of the turntable 7 and a connecting block 52 is provided on the right side. The vertical rod 51 is a square rod structure. The front and rear widths of the vertical rod 51 match the width of the U-shaped groove 71. The connecting block 52 is hinged to the support seat 72 on the turntable 7 through a pin shaft 53. A torsion spring 54 is installed on the pin shaft 53 (see Figure 2 );
[0024] The limiting mechanism 6 is arranged below the U-shaped groove 71 to limit the vertical rod 51. The limiting mechanism 6 includes a U-shaped limiting block 61. The opening direction of the U-shaped limiting block 61 is consistent with the U-shaped groove 71. The limiting bolt 62 is threadedly installed in the middle of the U-shaped limiting block 61. The shaft of the limiting bolt 62 passes through the U-shaped limiting block 61 and abuts against the right side of the vertical rod 51. The limiting bolt 62 is locked and positioned by a locking nut 63 (see Figure 3 );
[0025] The side balancing mechanism 8 includes a positioning column 81 whose upper end is fixed to the turntable 7, a balancing positioning block 82 is installed at the lower end of the positioning column 81 and forms a free rotation structure through a rolling bearing 83, and an annular groove 821 is processed in the middle of the balancing positioning block 82, and the size of the annular groove 821 matches the edge of the glass 3.
[0026] The device installs the grinding knife and the balance positioning block correspondingly under the turntable. The grinding knife is installed in a swinging manner with the turntable through the knife holder assembly, which is convenient for placing the glass. The balance positioning block is used to limit the edge of the glass to prevent the glass from being cracked due to uneven force on both sides during grinding. As the turntable rotates, the balance positioning block cooperates with the grinding knife to grind the edge of the glass. The overall structure of the device is simple, positioning is convenient, and grinding efficiency is high.
[0027] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;
[0028] The glass shape in this embodiment refers to a circle;
[0029] When working, push the upper end of the vertical rod toward the center of the turntable, and the lower part of the vertical rod drives the grinding knife to deflect outward clockwise with the pin as the center. Then place the glass on the base, keep the center of the glass corresponding to the center of the turntable, and the edge of the glass is embedded in the annular groove of the balance positioning block, and is positioned by suction through the vacuum suction cup. Then loosen the vertical rod, and the vertical rod uses the elastic memory of the torsion spring to flip counterclockwise and reset. The grinding surface on the inside of the grinding knife just rests on the edge of the glass. At this time, the end of the limit bolt in the middle of the U-shaped limit block does not contact the side of the column, and there is a certain gap. After the glass is positioned, The driving shaft drives the turntable to rotate, and the grinding knife grinds along the circumferential direction of the glass as the turntable rotates. The grinding knife always sticks to the edge of the glass under the elastic memory effect of the torsion spring until the end of the limit bolt in the middle of the U-shaped limit block abuts against the side of the column to form a limit. The limit bolt can adjust the grinding amount within a certain range. When the grinding is completed and the glass is to be removed, the upper end of the vertical rod is pushed toward the center of the turntable again, and the lower part of the vertical rod drives the grinding knife to deflect outward clockwise with the pin as the center. The grinding knife is disconnected from the edge of the glass, and the vacuum suction cup is disconnected from the glass, and the glass can be removed.
[0030] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
