Technical field

The utility model relates to the warp knitting machine technical field, especially a kind of transmission mechanism that is used to control guide bar shogging motion on the warp knitting machine.

Background technology

The control device of guide bar shogging was made up of floral disc or chain piece on the warp knitting machine in the past, such device has shortcomings such as slow, the traversing distance of speed is little, low precision, noise height, changing the flower type also relatively wastes time and energy, and the restoring force by back-moving spring makes the sley bar counter motion, thereby strengthened the resistance of positive movement, aggravated the wearing and tearing of member.Guide bar shogging device on the present warp knitting machine is for providing a kind of high efficient and convenient guide bar shogging transmission mechanism, and the small and exquisite more multi-bar jacquard warp knitting machine of sley bar that is specially adapted to of its mechanism.This cover control device mainly is made up of the top headstock of servomotor, ball screw, nut sleeve, linear guide and convertible angle.Servomotor control ball screw rotates, and ball screw is converted to straight-line displacement with rotation, drives top headstock, has top and pull hook nut to link with sley bar on the top headstock, the control guide bar shogging.This device has overcome a lot of shortcomings of original floral disc and chain piece Traverse Displacement Unit.

But also there is other shortcoming in the transmission mechanism of above-mentioned warp knitting machine guide bar shogging, and linear guide is exposed outside, is subjected to the wearing and tearing of the pollution aggravation machinery of dust easily in daily use, and installs inconvenient; Top headstock is fixed in addition, is difficult to cooperate with sley bar, will change the sley bar position usually and cooperate the ball screw Traverse Displacement Unit, and is very inconvenient.

The utility model content

The utility model provides a kind of transmission mechanism of warp knitting machine guide bar shogging, to solve technical problems such as original device weak point in service life, installation inconvenience.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of transmission mechanism of warp knitting machine guide bar shogging, comprise servomotor, Connection Block, screw component, top headstock and support, be connected by Connection Block between servomotor and the screw component, the screw component other end connects top headstock, the below frame has support, described screw component comprises casing, front shroud, back shroud, bearing, ball screw, nut sleeve, guide pillar and linear bearing, back shroud is provided with bearing, back shroud and front shroud are packed in the two ends of casing respectively, the bearing that places the ball screw rear end in the casing to pass on the back shroud stretches out casing, be connected with the spindle nose of servomotor, the ball screw front end passes front shroud and stretches out casing and be connected with screw axis, nut sleeve is sleeved on the ball screw, a fixedly connected linear axis holds on the nut sleeve, linear bearing is sleeved on the guide pillar, and the nut sleeve leading portion passes front shroud and stretches out casing and be connected with top headstock, and top headstock is provided with top and pull hook nut.

The utility model has solved the defective that exists in the background technology, and full-enclosed structure helps maintaining, has prolonged mechanical service life greatly; The top headstock of variable-angle is convenient to install, and effectively utilizes the limited space of warp knitting machine head section.

The specific embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As Fig. 1, shown in 2, a kind of transmission mechanism of warp knitting machine guide bar shogging, comprise servomotor 1, Connection Block 2, screw component, top headstock 6 and support 7, be connected by Connection Block 2 between servomotor 1 and the screw component, the screw component other end connects top headstock 6, the below frame has support 7, described screw component comprises casing 4, front shroud 5, back shroud 3, bearing 12, ball screw, nut sleeve 14, guide pillar 15 and linear bearing 16, back shroud 3 is provided with bearing 12, back shroud 3 and front shroud 5 are packed in the two ends of casing 4 respectively, the bearing 12 that places the ball screw rear end in the casing 4 to pass on the back shroud stretches out casing 4, be connected with the spindle nose of servomotor 1, the ball screw front end passes front shroud 5 and stretches out casing 4 and be connected with screw axis 9, nut sleeve 14 is sleeved on the ball screw, a fixedly connected linear axis holds 16 on the nut sleeve 14, linear bearing 16 is sleeved on the guide pillar 15, nut sleeve 14 leading portions pass front shroud 5 and stretch out casing 4 and be connected with top headstock 6, and top headstock 6 is provided with top 18 and pull hook nut 19.

Servomotor 1 is fixedlyed connected with screw axis 9 by shaft coupling 8 during installation, and ball screw is positioned at casing 4 inside, and the bearing 12 that its rear end is passed on the back shroud 3 stretches out casing 4, and is fixing by nut 10, and oil sealing sealing.Box house nut sleeve 14 is sleeved on the screw mandrel, a fixedly connected linear axis holds 16 on the nut sleeve 14, linear bearing 16 is sleeved on the guide pillar 15, and nut sleeve 14 leading portions pass front shroud 5 and stretch out casing 4 and be connected with top headstock 6, and top headstock 6 is provided with top 18 and pull hook nut 19.

Main motion as device partly is servomotor, screw axis, nut sleeve and top headstock.According to the requirement of flower type, servomotor drives screw axis and rotates, threaded engagement between screw axis and the nut sleeve changes rotation into the rectilinear motion of nut sleeve and top headstock, because of the linear bearing that is provided with on the nut sleeve is sleeved on the guide pillar, torsion suffered on the nut sleeve is offset by guide pillar, again because guide pillar is parallel with ball screw, stressed even when nut sleeve is moved on screw mandrel, motion is steady, and the rectilinear motion driving sley bar with top headstock laterally moves around then.

Guide pillar is the inside that is in casing simultaneously, with screw axis and casing oil bath lubrication of nut sleeve coexistence, the utlity model has maintaining conveniently with respect to being installed separately of original device, the advantage of compact conformation, and can avoid entering of dust, alleviate mechanical wear, prolong parts service life.The slave part of original device is connected with screw axis by screw mandrel, and the utility model is made of one screw mandrel and nut sleeve, makes structure more stable, and is easy for installation.

The installation of top headstock as shown in Figure 4, wherein the angle of top headstock is to adjust according to the angle of sley bar, has avoided original device must to meet the demands by the setting angle of adjusting casing when mounted like this, greatly facilitates and installs and later adjustment.

The utility model does not limit to and said structure, is equally applicable to other mechanism, as long as utilized above-mentioned composition member, all belongs to the scope that the utility model comprises.
