Abstract

The utility model discloses a needle transferring cam structure of a flat knitting machine. The needle transferring cam structure comprises two bodies of which two centers are symmetrical, wherein each body comprises a transverse plane and an inclined plane integrated with the transverse plane; an acute angle is formed between the inclined plane and the upper end face of the transverse plane; the lower end face of the transverse plane is provided with a downward trapezoid-shaped bulge; the inclined plane is provided with a needle transferring plane of which the shape is matched with the trapezoid-shaped bulge; and the needle transferring plane and the bulge form a needle moving track. The inclined plane further includes a first needle moving plane and a second needle moving plane, and one end of each of the first and the second needle moving planes is connected with the needle transferring plane. The needle transferring cam structure of the flat knitting machine solves the technical problem that a cam is locked dead easily in the prior art, and saves an auxiliary electric control unit for switching a middle cam and the needle transferring cam, therefore, the needle transferring cam is simple and reliable in design and can lower the failure rate.

Description

Flat machine turn over the pin three-legged structure

Technical field

The utility model belongs to technical field of knitting machinery, and what especially relate to a kind of flat machine turns over the pin three-legged structure.

Background technology

Flat machine need shift the coil of two needle-bars when styles such as braiding rib-loop and flat pin, different rib-loop structures; This process is for turning over pin, and the design of Computerized flat knitting machine stitch track when turning over pin is through middle mountain triangle and the switching up and down of turning over the pin triangle at present; Cooperate the running rail that forms stitch when turning over pin with sharp mountain by turning over the pin triangle; The shortcoming of this structure is: because switching needs auxiliary electric control gear up and down, and complex structure, and be prone to stuck phenomenon.

The utility model content

What the purpose of the utility model provided flat machine turns over the pin three-legged structure, its simplicity of design, and the electric control gear that need not assist can stably be accomplished smoothly and turn over the pin action.

For this reason; The technical scheme that the utility model adopts is: flat machine turn over the pin three-legged structure; It is characterized in that: comprise two centrosymmetric bodies, said each body includes an inclined-plane of a plane of structure and affiliated plane of structure global formation, and the upper end of affiliated inclined-plane and plane of structure forms acute angle; Under to have a downward trapezoidal shape protruding the lower surface of plane of structure; Said inclined-plane has the dial of turning over, and said dial shape and the protruding coupling of trapezoidal shape of turning over is with the affiliated track that takes the needle that convexes to form; Said inclined-plane comprises that also first walks dial and second and walk dial, said first walk a end that dial and second walks dial respectively with turn over dial and link to each other.

Further improvement as to the utility model is: first walk dial and second walk dial respectively with turn over the dial arc transition and be connected; Described trapezoidal shape is protruding to be connected with plane of structure lower surface arc transition.

Sharp mountain triangle before the trapezoidal shape convexity of the utility model is equivalent to; With trapezoidal shape protruding with turn over the design of pin triangle track at a body; Thereby form a fixing pin triangle track that turns over, make the utility model overcome the prior art intermediate cam and occur stuck technical problem easily, also saved simultaneously auxiliary electric control gear come to switch up and down in the mountain trigonometric sum turn over the pin triangle; Therefore the utility model simplicity of design is reliable, can reduce the generation of fault rate.

Turning in the pin triangle track of the utility model has certain fillet, has cushioning effect, can prevent that pin bell and three angle surfaces from producing excessive impact.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.

Fig. 1 is the sketch map of the utility model.

The specific embodiment

Referring to Fig. 1.This specific embodiment comprises two symmetrical bodies 5 and body 6, and body 5 has a plane of structure and an inclined-plane are arranged, plane of structure and inclined-plane global formation; The lower surface of plane of structure has an outstanding downwards trapezoidal shape protruding 1, protruding 1 and links to each other with the lower surface arc transition of plane of structure, can prevent the impact of pin bell to corner block; The inclined-plane of body 5 has the dial of walking 2; Walk dial 2 and form acute angle with the plane of structure upper end, also comprise on the inclined-plane and turn over dial 4, the shape of turning over dial 4 adapts with protruding 1; Present embodiment comprises that also second walks dial 3, the second and walk dial 3 and turn over dial 4 arc transition and be connected.

Claims

Flat machine turn over the pin three-legged structure, it is characterized in that: comprise two centrosymmetric bodies, said each body includes an inclined-plane of a plane of structure and affiliated plane of structure global formation, the upper end of affiliated inclined-plane and plane of structure forms acute angle; Under to have a downward trapezoidal shape protruding the lower surface of plane of structure; Said inclined-plane has the dial of turning over, and said dial shape and the protruding coupling of trapezoidal shape of turning over is with the affiliated track that takes the needle that convexes to form; Said inclined-plane comprises that also first walks dial and second and walk dial, said first walk a end that dial and second walks dial respectively with turn over dial and link to each other.
Flat machine as claimed in claim 1 turn over the pin three-legged structure, it is characterized in that: first walk dial and second walk dial respectively with turn over the dial arc transition and be connected; Described trapezoidal shape is protruding to be connected with plane of structure lower surface arc transition.
