Utility model content:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of optical-fiber laser cutting machine, its reasonable in design, adopt the drive mechanism that guide rail coordinates with tooth bar, and at rack and pinion engagement place, automatic takeup is installed, clearance distance between rack-and-pinion can be adjusted automatically, rack meshing clearance is consistent, both rack and pinion engagement tension had been eliminated and the excessive wear produced, turn eliminate rack and pinion engagement and cross pine and the movement clearance produced, mechanical stability against short circuit is good, cutting speed is fast, cutting accuracy is high, improve production efficiency, reduce production cost, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of optical-fiber laser cutting machine, comprise fuselage, be movably arranged on the crossbeam on fuselage and be movably arranged on the laser head combination unit on crossbeam, be respectively equipped with tooth bar and the guide rail of a parallel interval setting in fuselage upper surface both sides along fuselage length direction, be slidably mounted on respectively bottom crossbeam both sides on two guide rails, bottom crossbeam both sides, respectively by motor, one gear be meshed with tooth bar is installed, the tensioning apparatus that one is arranged on crossbeam two side bottom is respectively equipped with between each gear with corresponding tooth bar, described tensioning apparatus comprises one and is arranged on fixed head bottom crossbeam, one end of one tensioning support is connected by rotating shaft with fixed head, gear shaft on the upside of the middle part of tensioning support and gear is movably connected, the bolt activity be positioned at above tooth bar that the other end of tensioning support and is vertically mounted on fixed head socket-connects, at the threaded one end sheathed nut of bolt away from fixed head, a spring is arranged with outside bolt between tensioning support and nut.
The utility model adopts such scheme, its reasonable in design, crossbeam is by tooth bar and the two kind of drive motion of guide rail, crossbeam is linearly moved by guide rail, stable transmission is reliable, and at rack and pinion engagement place, automatic takeup is installed, the spring of automatic takeup and bolt automatically adjust the clearance distance of rack-and-pinion in crossbeam motion process, rack meshing clearance is consistent, both rack and pinion engagement tension had been eliminated and the excessive wear produced, turn eliminate rack and pinion engagement and cross pine and the movement clearance produced, mechanical stability against short circuit is good, cutting speed is fast, cutting accuracy is high, improve production efficiency, reduce production cost.

Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of optical-fiber laser cutting machine, comprise fuselage 1, the laser head combination unit 3 being movably arranged on the crossbeam 2 on fuselage 1 and being movably arranged on crossbeam 2, tooth bar 4 and the guide rail 5 of a parallel interval setting is respectively equipped with in surperficial both sides on the fuselage 1 along fuselage 1 length direction, be slidably mounted on two guide rails 5 bottom crossbeam 2 both sides respectively, bottom crossbeam 2 both sides, respectively by motor, one gear 6 be meshed with tooth bar 4 is installed, the tensioning apparatus that one is arranged on crossbeam 2 liang of side bottoms is respectively equipped with between each gear 6 with corresponding tooth bar 4, described tensioning apparatus comprises one and is arranged on fixed head 7 bottom crossbeam 2, one end of one tensioning support 8 is connected by rotating shaft 9 with fixed head 7, gear shaft 13 on the upside of the middle part of tensioning support 8 and gear 6 is movably connected, bolt 10 activity be positioned at above tooth bar 4 that the other end of tensioning support 8 and is vertically mounted on fixed head 6 socket-connects, at the threaded one end sheathed nut 11 of bolt 10 away from fixed head 6, a spring 12 is arranged with outside bolt 10 between tensioning support 8 and nut 11.
During use, staff can pass through rotating nut 11 Compress Spring 12 in advance, pressure is passed to tensioning support 8 by spring 12, tensioning support 8 pairs of gears 6 are exerted pressure thus are made gear 6 near tooth bar 4, then motor is opened, electric machine rotation acts on gear 6, gear 6 is moved on tooth bar 4, thus drive crossbeam 2 to move on tooth bar 4 and guide rail 5, crossbeam 2 is by tooth bar 4 and guide rail 5 pairs of kind of drive motions, crossbeam 2 is linearly moved by guide rail 5, tooth bar 4 is installed because objective factor cannot reach absolute linear pattern, namely there will be place uneven with guide rail 5, because gear 6 tooth bar 4 is when running with guide rail 5 not parallel part, there will be engagement too tight or too loose, cause between gear 6 tooth bar 4 and occur wearing and tearing or gap, have impact on the stability of crossbeam 2 operation and the life-span of gear 6 tooth bar 4, and automatic takeup can regulate this situation, namely the spring 12 of automatic takeup adjusts the clearance distance of gear 6 tooth bar 4 in crossbeam 2 motion process automatically with bolt 10, gear 6 tooth bar 4 back lash is consistent, both eliminate gear 6 tooth bar 4 and engage tension and the excessive wear produced, turn eliminate the movement clearance that gear 6 tooth bar 4 engaged pine and generation, mechanical stability against short circuit is good, cutting speed is fast, cutting accuracy is high, improve production efficiency, reduce production cost.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
