Shuttle race gear pair in existing embroidery machine in shuttle race system adopts bevel gear pair 14, it is the vertical-transmission of level, such structure make the position of lower shaft be same rotating shuttle at grade, front and back drive the rigidity of connected connecting plate 3 to increase space reduction, this drives connected connecting plate also to lengthen accordingly before and after just causing when Y embroidery breadth is larger, and the thickness of its connecting plate can not increase all the time accordingly, cause Y-direction embroidery pattern when breadth is larger easily to walk, have a strong impact on embroidery quality; In addition, because the driving drive mechanism form in current computer embroidering machine is to rely on major-minor belt pulley, by belt, turn round connection, then by driving connection before and after connecting plate, form transmission to drive tabouret.This structure driven precision is low, because front and back drive, need to connect by connecting plate, so surely have alignment error in installing, affects transmission accuracy.
Utility model content
The utility model provides a kind of pinion and-rack Tabouret actuating, makes the running of driving mechanism more stable, and precision is higher, fundamentally promotes quality and the exquisite degree of embroidery.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: pinion and-rack Tabouret actuating, comprise driving, drive middle part one side to be provided with support, shuttle race is installed on support, described shuttle race is provided with shuttle race gear pair and lower shaft, shuttle race gear pair drives lower shaft outputting power, above driving, be provided with connecting plate, described driving drives connecting plate, described connecting plate front end and rear end are connected with front and the rear shelves of tabouret, described shuttle race gear pair is comprised of a pair of intermeshing helical gear, described driving comprises that cross section is the driving seat of the rectangular structure of U-shaped, between described driving seat and connecting plate, be provided with sliding track mechanism, the bottom surface of described connecting plate is provided with a tooth-arranging strip along its length, in described driving, be provided with wheel and rack engagement, described driving one side is provided with drive unit driven wheel.
Preferably, described sliding track mechanism comprises the roller that drives seat oral area both sides to arrange along its length, and described roller ring is circumferentially with roller groove, and the both sides of described connecting plate are provided with traveller and coordinate with roller groove.
Preferably, described front and rear shelves bottom are provided with a grade groove, and the front end of described connecting plate and rear end are provided with driving bearing and coordinate with shelves groove.
First the utility model is designed to shuttle race gear pair one group of vertical Helical gear Transmission with shaft position under reducing in shuttle race system, thereby the connecting plate thickness driving before and after can making increases, connecting plate rigidity can increase greatly, has guaranteed stability and the embroidery quality of Y-direction embroidery pattern when breadth is larger.
Secondly, the utility model drives original front and back to be joined together to form an integral drive, transmission outgoing position is driving middle part, tooth bar engagement by gear and connecting plate bottom surface drives connecting plate, again connecting plate is directly installed on and drives the sliding track mechanism above passing through between driving and connecting plate as guiding, directly form transmission to drive tabouret, the advantage of this structure is that connecting plate is directly installed in driving makes structure compacter, to improve installation accuracy, the direct-drive form of tooth bar connecting plate by travelling gear improved precision when tabouret is embroidered back and forth greatly, make embroidery more attractive in appearance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
