Taboret high-precision driving device of computer embroidery machine
Technical field
The utility model relates to a kind of drive unit of computer embroidering machine tabouret, particularly a kind of Taboret high-precision driving device of computer embroidery machine that is used to drive tabouret.
Background technology
The drive unit of existing computer embroidering machine tabouret, the driving coaster that uses on it, except be subjected to motor synchronizing band level to driving force and the translation, also to be subjected to the effect of upper pulling force, and the effect of upper pulling force, make that not only the rolling bearing that drives coaster damages easily, cause production cost to increase, and, tremble easily owing to drive the effect that coaster is subjected to two kinds of power, influence the precision of institute's clock, reduced product quality.
Summary of the invention
The purpose of this utility model is to provide a kind of Taboret high-precision driving device of computer embroidery machine.
To be solved in the utility model is the problem that existing tabouret drive unit is fragile and the generation of driving coaster is trembleed.
In order to achieve the above object, the technical scheme that provides of the utility model is:
It comprises supporting base, synchronous belt tension device, be located at synchronous band main wheel on the supporting base, be located at synchronous band accessory whorl on the synchronous belt tension device, be placed in the synchronous band on synchronous band main wheel and the accessory whorl.Be provided with first guide rail and second guide rail between supporting base and the synchronous belt tension device, on first guide rail and second guide rail driving coaster be housed, the driving coaster is fixed on synchronously to be with.
Use the utility model on computer embroidering machine, the rolling bearing loss that not only drives coaster is little, service time is long, and it is stable to drive coaster, has guaranteed the precision of institute's clock, has improved the quality of product greatly.
