Description
Technical field
The utility model is related to the component of computerized emboridering machine, particularly relate to a kind of for driving the novel of tabouret precise positioning
Tabouret driving device.
Background technology
Computer embroidery machine frame drive apparatus mainly by motor and driving guideway form, driving guideway include guide rail and
Sliding block, motor generate displacement by transmission mechanism control slide block movement, the tabouret of fixed cloth with the movement of sliding block.It is existing
Sliding block on be typically provided with guide wheel, the two sides of guide rail are equipped with axial guide-track groove, are cooperated by guide wheel and guide-track groove, sliding
Block can the free movement on guide rail.For guide wheel when being rolled on guide-track groove, contact area is larger, this will cause guide wheel and guide-track groove
Between the larger frictional force of generation, in addition, when sliding block on guide rail when moving, the side of guide wheel can be sent out with the groove of guide-track groove
Raw slight impact and friction, this can not only further increase frictional force during slide block movement, but also guide rail can be generated larger
Abrasion, ultimately causing sliding block cannot accurately be slided, so as to influence the precise positioning of tabouret.
Utility model content
The utility model provides a kind of Tabouret driving device of brand new, and its object is to the prior art is overcome to exist
Frictional force it is larger and positioning it is not accurate the problem of.
The technical solution of the utility model is as follows：
A kind of novel tabouret driving device, including driving guideway, the driving guideway includes sliding block and guide rail, described
The two sides of guide rail are equipped with the guide-track groove being longitudinally extended, and sliding block matches to merge with guide-track groove to be installed on guide rail, the driving guide rail
Pair further includes at least four balls, and the sliding block is in " ∏ " shape, it includes two side plates, and the inner wall of each side plate offers
With the recessed portion of the spheric of ball engagement, the side of each ball and recessed portion are against opposite side is resisted against in guide-track groove.
Further, it is opened up on each side plate there are three recessed portion arranged in a straight line, phase is mounted in each recessed portion
The ball answered.
Further, the cross section of the guide-track groove is arc-shaped.
Further, the cross section of the guide-track groove is two symmetrical inclined surface, the ball and two inclined surface
Line contacts.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the advantage of：This reality
Guiding wheel structure is substituted using roll structure with novel, the motion mode between sliding block and guide rail is improved, and is not only caused
Overall structure is more stablized, and considerably reduces frictional force, is conducive to realize precise positioning to sliding block.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Embodiment one
Fig. 1 is a kind of novel tabouret driving device, and including driving guideway, the driving guideway includes sliding block 1, guide rail
2 and four balls 3, the two sides of the guide rail 2 are equipped with the guide-track groove 4 being longitudinally extended, and the cross section of the guide-track groove 4 is in circular arc
Shape, it is adapted with the size of ball 3.The sliding block 1 is in " ∏ " shape, it includes a top plate 11 and two side plates 12, top plate
11 and side plate 12 be integrally formed, sliding block 1 is set up on guide rail 2, and the equal compartment of terrain of inner wall of each side plate 12 opens up that there are two recessed
Concave portion 13, the recessed portion 13 are the spheric coordinated with ball 3, and the side of each ball 3 and recessed portion 13 are against another
Side is resisted against in guide-track groove 4.During work, sliding block 1 can move back and forth under the driving of motor (being not drawn into figure) on guide rail 2.
The utility model substitutes Guiding wheel structure using roll structure, and the motion mode between sliding block 1 and guide rail 2 is improved, no
Only so that overall structure is more stablized, and considerably reduces frictional force, be conducive to realize precise positioning to sliding block 1.
The quantity of ball 3 can be configured according to actual needs, as long as even number and symmetrically it is installed on 2 both sides of guide rail
, when opening up three recessed portions 13 arranged in a straight line on the side plate 12, and it is respectively mounted in each recessed portion 13 corresponding
During ball 3, sliding block 1 is more steady when rolling.
In addition, for the ease of being lubricated to ball 3, oil filler point 5 can be also opened up on the both side plate 12 of sliding block 1, thus
Solve the problems, such as that oiling bothers so that the service life of Tabouret driving device is extended.
Embodiment two
The structure of the present embodiment and above-described embodiment one is essentially identical, and the main distinction is, the guide-track groove 4 it is transversal
Face is two symmetrical inclined surface 41, and the ball 3 is contacted with two inclined surface, 41 line, the roll mode of this line contact,
The contact area of ball 3 and guide-track groove 4 is reduced, can further reduce frictional force when ball 3 rolls.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept belong to invade the row of scope of protection of the utility model
For.
