Description
Technical field
Tricot machine field is the utility model is related to, more particularly to a kind of guide bar shogging device.
Background technology
The guide bar shogging device of traditional tricot machine usually based on chain block, floral disc control, generally adopt by chain block formula traverse displacement unit
Sley bar is driven with chain block, chain block formula traverse displacement unit is that the chain block with different height is formed end to end chain to be sleeved on card
Guide bar shogging is controlled on roller；Faceplate type traverse displacement unit generally uses the convex dish driving sley bar of dish type, and the surface of the convex disk of dish type is by comb
The traversing amount of comb forms profile, profile control guide bar shogging.Transverse movement precision is low, running speed is low, larger to flower type structure limitation, more
Change flower pattern inconvenience.The device have speed it is slow, it is traversing apart from it is small, ring the changes on it is slow, change that colored cost is big, circulation course count is few, control
Sley bar number processed is few, transverse movement precision poor (having the shortcomings that accumulated error), cumbersome, occupied space is big and noise is big.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of control guide bar shogging distance, it is simple in structure, be easy to
The guide bar shogging device of maintaining.
Technical solution is used by the utility model solves its technical problem：
A kind of guide bar shogging device, including servomotor, lead screw assembly and frame, lead screw assembly are installed on the interior of frame
Portion, servomotor are fixedly mounted on the outside of frame and drive lead screw assembly, lead screw assembly include cooperate screw and
Screw, lower portion are installed with two screw rodb bases, and screw is horizontally disposed with and its both ends is installed in rotation on screw rodb base
On, the right end of screw is fixedly connected with the output shaft of servomotor, and two firm seats are equipped between two screw rodb bases, and two are firm
Seat is fixedly mounted on frame and is connected between two firm seats by firm bar, and firm bar and screw are arranged in parallel, screw
Between two firm seats and it is slidably mounted on firm bar, one end of telescopic rod is fixedly connected with screw, another
End is stretched out frame and is connected with sley bar.
Further, screw is slideably set on firm bar by being secured to the nut sleeve of connection.
Further, be installed with connecting plate on nut sleeve, one end of telescopic rod and connecting plate be threadedly coupled and
It is fixed under the action of nut on connecting plate.
Further, screw uses unidirectional screw or reciprocating screw rod, and during using unidirectional screw, servomotor passes through rotating
Mode drive screw rotating, screw drives the screw reciprocating motion supporting with it；During using reciprocating screw rod, servomotor leads to
The mode for crossing single direction rotation drives screw to rotate, and screw drives the screw supporting with it to move back and forth.
The beneficial effects of the utility model are：This guide bar shogging device drives screw to rotate by servomotor, controls silk
Female rectilinear direction moves back and forth, and so as to fulfill the traversing distance of guide bar shogging device is changed at any time, and firm bar causes silk
It is female more to stablize when moving back and forth, eliminate moment of torsion of the screw to telescopic rod.
Brief description of the drawings
Fig. 1 is the schematic front view of the utility model；
Fig. 2 is the schematic perspective view of the utility model.
In figure：1 servomotor, 2 lead screw assemblies, 21 screws, 22 screws, 3 frames, 4 screw rodb bases, 5 firm seats, 6 firm bars,
