Description
Technical field
The utility model relates to the adjusting device of centre-to-centre spacing between a kind of rolling wheel guide rails two side wheels.
Background technology
Rolling wheel guide rails on the laser engraving cutting equipment, is very high to its requirement particularly as common components on the industrial equipment.Because roller when particularly precision being calibrated, will be adjusted the centre-to-centre spacing of roller between the guide rail both sides after at the frequent high speed scroll in the both sides of guide rail, using for a long time.In the prior art, the device that centre-to-centre spacing between this pair roller is adjusted, comprise connecting plate 11, eccentric nut 13, roller 12 and centration axis 14, described roller 12 is enclosed within on the described centration axis 14, and be central shaft with centration axis 14, have through hole on the described connecting plate 11, this through hole is a chute, makes centration axis 14 move in chute, has screw thread on the described centration axis, and with the eccentric orfice of eccentric nut coupling, a limiting plate 16 is set on connecting plate, this limiting plate contacts with eccentric nut, owing to have eccentric orfice on the eccentric nut, so it just utilizes the rotation change eccentric orfice of eccentric nut and the distance of limiting plate, and mobile centration axis.Moving of centration axis and drive the change of distance between the roller.After the centre-to-centre spacing of two roller times is adjusted, need be fixed, thereby a jackscrew 15 is set also on the eccentric nut of this adjusting device, this jackscrew is actually a bolt, after jackscrew moves down, withstand connecting plate, make eccentric nut not move, could fix adjusted centre-to-centre spacing.But the adjusting device of this structure is after jackscrew withstands connecting plate, and eccentric nut is owing to be subjected to stress upwards on a position, and eccentric nut is tilted, and because centration axis can move freely in chute, also can tilt and drive centration axis, finally cause roller to tilt.So when adjusting centre-to-centre spacing between the roller, can increase the frictional force of roller and guide rail, make very quick-wearing of roller with the adjusting device of this structure, gap between roller and guide rail is increased, finally cause the reduction of precision, particularly use on laser equipment, the consequence that causes is more serious.So the device of this structural adjustment, its centration axis does not reach the requirement of centering, and centration axis is in swing state at work, and transmission is not steady, has reduced transmission accuracy, produces noise; On laser equipment, can not realize the requirement of high-speed cutting engraving well.
The utility model content
Deficiency in view of the background technology existence, the technical problems to be solved in the utility model provides and a kind ofly can make rolling wheel guide rails roll rail centre-to-centre spacing to be easy to adjust, and make adjusted roller center fixation constant, thereby produced the raising transmission accuracy, the adjusting device of the rolling wheel guide rails roller centre-to-centre spacing of smoothness of operation.
For this reason, the utility model is realized by the following technical solutions: a kind of adjusting device of rolling wheel guide rails roller centre-to-centre spacing, comprise connecting plate, eccentric nut, roller and centration axis, described roller housing is on described centration axis, and be central shaft with the centration axis, has first through hole on the described connecting plate, described centration axis is connected with described eccentric nut, it is characterized in that described eccentric nut has an extension, first through hole coupling on the external diameter of this extension and the described connecting plate, and this extension has eccentric orfice, the coaxial setting of second through hole on this eccentric orfice and the described eccentric nut, and mate with centration axis; Have threaded third through-hole on the described eccentric nut, in described third through-hole, be provided with jackscrew with its screw thread coupling; The axle sleeve of described roller is provided with packing ring.
In the utility model, its eccentric nut and eccentric extension constitute a multidiameter, and after the through hole coupling on its extension and the connecting plate, its eccentric throw is rotated the centre-to-centre spacing that has changed between roller with multidiameter, and its centre-to-centre spacing is easy to adjust; Because closely cooperating of multidiameter and connecting plate can not make centration axis tilt yet after jackscrew holds out against; And make the roller center fixation behind the accent constant, thus improve transmission accuracy and smoothness of operation, reduced noise, can be widely used in high-rate laser cutting, the engraving machine.

The specific embodiment
With reference to accompanying drawing, the adjusting device of rolling wheel guide rails roller centre-to-centre spacing, comprise connecting plate 1, eccentric nut 5, roller 2 and centration axis 7, described roller 2 is enclosed within on the described centration axis 7, and be central shaft with centration axis 7, has first through hole 4 on the described connecting plate 1, has screw thread on the described centration axis 7, and is connected with eccentric orfice 6 coupling of eccentric nut 5, described eccentric nut 5 has an extension 8, and first through hole 4 on the external diameter of this extension 8 and the described connecting plate 1 mates, and this extension 8 has eccentric orfice 11, second through hole, 6 coaxial settings on this eccentric orfice 11 and the described eccentric nut 5, and with centration axis 7 couplings, form a multidiameter with eccentric orfice.Have threaded third through-hole 9 on the described eccentric nut 5, in third through-hole 9, be provided with jackscrew 10 with its screw thread coupling; The axle sleeve of described roller 2 is provided with packing ring 3.
After being installed in the adjusting device of this structure on the exterior rolling wheel guide rails, roller 2 rolls on guide rail 17, side at connecting plate 1 is installed this adjusting device, opposite side is the fixed axis roller, just can regulate by this adjusting device the centre-to-centre spacing between guide rail two side wheels, when eccentric nut 5 is angle of rotating shaft rotation with centration axis 7, eccentric nut 5 turns over equal angular together with centration axis 7, roller 2 on the centration axis 7 is also in company with changeing together angle, because eccentric nut 5 all has eccentric orfice with its extension 8, that is to say, the eccentric orfice 11 wall thickness differences of its extension 8, therefore, the rotation of eccentric nut 5 has changed the centre-to-centre spacing between 17 liang of side wheels of guide rail.After adjusting to needed centre-to-centre spacing, be clamped on the connecting plate 1 with centration axis 7 and eccentric nut 5, and hold out against connecting plate 1 with jackscrew 10, work preventing the multidiameter rotation, and reach locking purpose; Because connecting plate 1 is a kind of aluminium alloy, thus packing ring 3 is set on the axle sleeve of roller 2, to prevent to weigh wounded connecting plate 1.Centration axis 7 has produced the centre-to-centre spacing adjustment in first through hole 4 of connecting plate 1 like this, roller 2 center fixation have been guaranteed, and roller 2 centers are not swung, do not produce deflection under external force yet, improved positioning accuracy, thereby improved transmission accuracy, can realize that improving speed moves reposefully, has reduced noise.It is all very convenient to adjust maintenance, and cost is lower than straight ball-guide.In the production of laser cutting machine, engraving machine, be used widely.
