DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" in the utility model are only for the convenience of clear description, and are not used to limit the scope of the utility model. The change or adjustment of the relative relationship is also regarded as the scope of the utility model without substantial change of the technical content.

[0023] Referring to Figures 1-4 A kind of positioning clamping mechanism based on numerical control cutting table for glass processing, including table body 1 and two L-shaped positioning blocks 7, horizontal groove 2 and vertical groove 3 are set up on the upper surface of table body 1, first threaded rod 4 is horizontally rotatably installed in horizontal groove 2, first threaded rod 4 is threadedly sleeved with first sliding block 5, the surface of first sliding block 5 is in sliding contact with the groove wall of horizontal groove 2, clamping plate 6 is fixedly installed on the top of first sliding block 5, second threaded rod 8 is horizontally rotatably installed in vertical groove 3, second threaded rod 8 is threadedly sleeved with second sliding block 9, the surface of second sliding block 9 is in sliding contact with the groove wall of vertical groove 3, one of positioning blocks 7 is fixedly installed on the upper surface of second sliding block 9, another positioning block 7 is fixedly installed on the upper surface of table body 1, and the positions of the two positioning blocks 7 correspond.

[0024] The end of first threaded rod 4 and second threaded rod 8 is all worn out table body 1, and is all fixedly installed with adjusting wheel.

[0025] First, the glass to be processed is placed on the upper surface of table body 1, and the surface is tightly abutted with the surface of positioning block 7 fixedly installed on the upper surface of table body 1, then second threaded rod 8 is rotated at this time, second sliding block 9 is controlled to move towards the direction close to another positioning block 7 with the positioning block 7 fixedly connected with itself, until the positioning block 7 is also tightly abutted with the surface of glass, then first threaded rod 4 is rotated again, first sliding block 5 is controlled to move towards the direction close to glass with clamping plate 6, until the glass is tightly clamped between clamping plate 6 and two positioning blocks 7, and the positioning and clamping work of glass can be completed.

[0026] Positioning block 7 upper surface is fixedly installed with mounting plate 10, mounting plate 10 surface is set with round mouth, and round mouth is provided with suction assembly, suction assembly is used to assist positioning glass, suction assembly includes plug rod 11 and suction disc 12 that are vertically slidably inserted in round mouth, and vertical groove is vertically set in the bottom end of plug rod 11, and suction disc 12 is fixedly installed at the bottom of plug rod 11 and is communicated with vertical groove.

[0027] When the two positioning blocks 7 clamp the glass between them, the insertion rod 11 can be controlled to move downward at this time, so that the suction cup 12 tightly abuts against the upper surface of the glass. The suction cup 12 is deformed under the abutting force, and the gas in the suction cup 12 flows out from the gap between the suction cup 12 and the glass, thereby forming adsorption with the glass, which can assist in positioning the glass, and can also avoid the transverse movement of the second sliding block 9, thereby improving the stability of the glass positioning.

[0028] The insertion rod 11 is sleeved with a rubber ring 13, which is fixedly installed in the round opening. The rubber ring 13 can increase the friction between the insertion rod 11 and the round opening, so that the insertion rod 11 will not move downward in the round opening under the influence of gravity without external force.

[0029] A plurality of air vents 14 are circumferentially arranged on the top of the insertion rod 11. A rotating opening is arranged at the center of the top of the insertion rod 11. A rotating shaft 15 is sealingly and rotatably installed in the rotating opening. A plurality of blocking pieces 16 for blocking the plurality of air vents 14 are circumferentially fixed on the surface of the bottom end of the rotating shaft 15.

The elastic component includes a torsion spring 17 sleeved on the rotating shaft 15. The two ends of the torsion spring 17 are fixedly connected with the fixed block and the insertion rod 11 respectively.

[0030] In the initial state, the plurality of blocking pieces 16 will block the plurality of air vents 14 under the elastic potential of the torsion spring 17. The plurality of air vents 14 are in a closed state at this time. When the adsorption of the suction cup 12 needs to be released, the plurality of blocking pieces 16 are rotated to no longer block the plurality of air vents 14 by rotating the rotating shaft 15. At this time, the plurality of air vents 14 are in an open state, and the gas outside will quickly enter the circular groove and the suction cup 12 from the plurality of air vents 14, so that the internal and external pressures of the suction cup 12 are consistent, and the adsorption between the suction cup 12 and the glass can be easily released.

[0031] The surfaces of the positioning blocks 7 and the clamping plates 6 are bonded with protective pads. The protective pads are made of rubber, which has good elasticity and adhesion. The rubber protective pads can increase the friction between the glass and the contact surfaces of the positioning blocks 7 and the clamping plates 6, and can also avoid damage to the surface of the glass caused by clamping.

[0032] The utility model discloses, first, the glass of processing is placed on the upper surface of the table body 1, and makes its surface closely with the surface of the locating block 7 fixedly installed on the upper surface of the table body 1, then this time rotates second threaded rod 8, control second sliding block 9 with the locating block 7 fixedly connected with itself moves towards the direction of approaching another locating block 7, until this locating block 7 also closely approaches the glass surface, then rotate first threaded rod 4 again, control first sliding block 5 with clamping plate 6 moves towards the direction of approaching the glass, until the glass is closely clamped between clamping plate 6 and two locating blocks 7, and the positioning clamping work of glass can be completed, it is convenient and fast, and clamping is stable, and positioning accuracy is high.

[0033] In the utility model, unless another definite provision and limitation, the terms "installation", "link", "connection", "fix" and so on terms should do broad sense understanding.

[0034] The above only for the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme of the utility model and the utility model concept of the utility model are replaced or changed, all should be covered in the protection scope of the utility model.
