The block locating mechanism of glass cutting machine
Technical field
The utility model relates to a kind of automatic positioning equipment of glass cutting machine, especially under any circumstance can both realize accurate localized block locating mechanism.
Background technology
The block locating mechanism of existing a kind of glass cutting machine is made up of cylinder, connecting rod, transmission shaft, block etc.The flexible of cylinder drives the transmission shaft rotation by connecting rod, and transmission shaft drives block by connecting rod again and moves or lifting, realizes the location to glass.This is located this locating mechanism and is locating vertical direction location with side, under the situation of prelocalization mode just, can bring deviation to the location of glass, its reason is: at the location minor face, pulley belt is inclined to one side with glass ribbon easily, particularly locating surface spills the thin glass of mildew-resistant powder, since not only light but also sliding, easier skew; Another existing side locating device (for example gondola Bao Teluo, Switzerland hundred surpass, and just their block moves and is not by rack-and-pinion) needs air-flotation system and assists the cost height.
Summary of the invention
In order to solve the high problem of deviations and use cost, the utility model provides a kind of block locating mechanism of glass cutting machine, this locating device not only can reduce to locate the error of bringing greatly, and can be in the location that does not have under the auxiliary situation of air supporting to realize to glass.
The technical scheme that its technical problem that solves the utility model adopts is: comprise guide rail beam, cylinder, connecting rod, transmission shaft and block, one end of the piston rod of cylinder and connecting rod is hinged, the other end of this connecting rod is fixedlyed connected with transmission shaft, and the cylinder body bottom and the guide rail beam of this cylinder are hinged; Described transmission shaft is rotatably installed on this guide rail beam, it is characterized in that: described block is installed on the described guide rail beam by the chute slide block mechanism, on this transmission shaft, gear is housed, on described chute slide block mechanism, the tooth bar that is meshed with described gear is housed.
Described chute slide block mechanism is made up of chute and slide block, and slide block embeds in the reducing groove of chute one side with being slidingly matched; Described block is connected on chute or the slide block, does not connect the chute of block or slide block and described guide rail beam and fixes.
Described reducing groove is a dovetail-indent.
The beneficial effects of the utility model are: can realize accurate location to glass with simple structure, the big and stable drive of rack-and-pinion transmission power can not have to promote glass under the auxiliary situation of air supporting simultaneously, has therefore saved the cost of air-flotation system.

Embodiment
Referring to Fig. 1 and Fig. 2, comprise guide rail beam 9, cylinder 7, connecting rod 6, transmission shaft 8 and block 1, the piston rod front fork 12 of cylinder 7 is hinged with an end of connecting rod 6, and the other end of connecting rod 6 is fixedlyed connected with transmission shaft 8.Air cylinder base 14 bottoms of this cylinder 7 are hinged with the cylinder free bearing 13 that is installed in guide rail beam 9 bottoms.Described transmission shaft 8 is rotatably installed on this guide rail beam 9 by rolling bearing units 5.Described block 1 is fixed on the slide block 3, and slide block 3 slides and embeds in the reducing groove of chute 2, and chute 2 is installed on the described guide rail beam 9 by back up pad 4.On described transmission shaft 8, gear 11 is housed, the tooth bar 10 that is meshed with described gear 11 is housed on described slide block 3.Reducing groove on the described chute 2 can be dovetail-indent.
The utility model is in working order the time, and it is flexible that pressurized air promotes the piston rod of cylinder 7, drives transmission shafts 8 rotations by connecting rod 6, transmission shaft 8 drives gear 11 rotations of fixing on it, move thereby drive the tooth bar 10 that is fixed on the block 1, realize moving of block 1, finish location glass.
Concrete working process is: cylinder 7 is in the position a period of time (shown in the solid line) among Fig. 2, block 1 is parked in the cutting bed edge, glass G in avoiding advancing (being arranged on the table top 15 on right side of Fig. 2 block 1), after cutter head detector switch to be cut detects glass and returns zero, cylinder 7 shrinks by connecting rod 6 and drives transmission shaft 8 rotations, be fixed on the also rotation simultaneously of gear 11 on the rotation axis 8, the rotating band carry-over bar 10 of gear 11 moves to the direction (right side among Fig. 2) near glass, moving of tooth bar 10 makes slide block 3 and the block 1 fixed on it also move (right side among Fig. 2) to glass along chute 2, when position two that cylinder 7 is contracted among Fig. 2 (among Fig. 2 shown in the two dot chain line), block 1 pushes away positive glass and realizes the location.After finished the location, cylinder 7 stretches out by position two got back to position one, made block 1 return-to-home position (cutting bed edge) by above-mentioned contrary transmission.Wherein, the position one among Fig. 2 is the position that cylinder 7 stretches out fully, and position two is all positions of withdrawal of cylinder 7.
