Abstract
The utility model discloses a shaft driving device with high precision operation, convenient maintenance and long service life, comprising a group of parallel driving shafts, the axis of the driving shaft is parallel to the horizontal plane, both extremities of the driving shaft are connected with the driving seat, a driving block is arranged on the driving shaft, a sleeve whose size of inner diameter engaged with the size of outer diameter of the driving shaft is positioned on the driving block, a screw is arranged on one end of connection between the driving shaft and the driving seat, wherein one end is pretightening screw, the axes of which is coincident with the axis of the driving shaft, another end is fixed screw, the axes of which is perpendicular to the axis of the driving shaft. The utility model is applicable to the drive of computer embroidery machine frame.
Description
Technical field
The utility model relates to a kind of drive unit that is used for computerized emboridering machine, relates in particular to a kind of axial brake device that has one group of driving shaft that is parallel to each other and drive block.
Background technology
At present on computerized emboridering machine, framework drives and generally adopts one group of driving shaft that is parallel to each other, the driving shaft two ends are installed on the drive seat, the employing screw that driving shaft two ends and drive seat have is fixed, perhaps an end adopts screw to fix, also there are two ends all not adopt screw to fix, driving shaft is provided with drive block, drive block is provided with the suitable sliding sleeve of outside dimension of internal diameter size and driving shaft, sliding sleeve is generally nylon bush or linear bearing, because frame size is bigger, thereby the driving shaft length in the axial brake device is also longer, and drive block is connected with framework, and drive block is provided with synchronous belt, synchronous belt moves drive block by belt wheel by driven by motor on driving shaft, thereby make framework along X to or Y to moving because framework can produce certain vibration and distortion in running, thereby make driving shaft produce flexural deformation by drive block, thereby the reduction running precision, influence embroidery precision; In addition, because sliding sleeve adopts nylon bush or linear bearing, in use need regularly to add lubricating oil, make troubles to maintenance, and the ABRASION RESISTANCE of nylon bush is relatively poor, the running noises of linear bearing is bigger.
Summary of the invention
The technical problems to be solved in the utility model provides the axial brake device of a kind of running precision height, easy to maintenance, long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises the one group of driving shaft that is parallel to each other, described drive axis is parallel to horizontal plane, described driving shaft two ends are connected with drive seat, described driving shaft is provided with drive block, described drive block is provided with the suitable sliding sleeve of outside dimension of internal diameter size and driving shaft, the end that described driving shaft is connected with drive seat is provided with screw, wherein an end is the pretension screw, its axial line and driving shaft axial line coincide, the other end is a hold-down screw, and its axial line and driving shaft axial line are perpendicular.
As further improvement, the material of described sliding sleeve is a polytetrafluoroethylene (PTFE).
As further improvement, described sliding sleeve two ends are provided with felt and link stopper successively.
As further improvement, described sliding sleeve periphery is provided with open slot.
Compared with prior art, the utlity model has following obvious advantage and beneficial effect:
1, running precision height.Because driving shaft adopts the pretension screw with the end that is connected of drive seat in the utility model, the other end adopts hold-down screw, and the pretension screw can make between driving shaft and the drive seat and produce pretightning force, with the distortion of minimizing driving shaft, thereby improves running precision.
2, easy to maintenance, long service life.Because the sliding sleeve material in the utility model adopts polytetrafluoroethylene (PTFE), improve ABRASION RESISTANCE, and in use need not to add lubricating oil, thereby long service life, easy to maintenance.
