Abstract

The utility model discloses a cam for embroidery machine head, including the cam body, drive shaft, connection drive shaft that the are used for usefulness annular chucking head with the cam body, as the improvement, first end of annular chucking or both ends be equipped with the shirt rim, the outer terminal surface cooperation of the back and shirt rim of cam body be connected. The utility model discloses one end or both ends at annular chucking head set up the shirt rim, and the dorsal surface cooperation of terminal surface and cam body is connected outside the shirt rim, very big increase the area of power transmission, make its arm of force increase, its beneficial effect is in the moment of torsion transmittance process, has reduced the damage of chucking head to the cam, can effectively lengthen the life of cam.

Description

A kind of machine head of embroidery machine cam

Technical field

The utility model relates to a kind of machine head of embroidery machine cam.

Background technique

The widely used cam of machine head of embroidery machine, in order to reach good lubrication effect, its material is generally nylon or plastics, and this is fixed on live axle by the clamping head be spirally connected thereon with regard to needing again.Along with the speed goes of high speed embroidery machine is high, the torsion that live axle passes to cam by clamping head is increasing, and the linkage structure of existing cam and clamping head can not meet the needs of high speed machine, and the cam life-span is far smaller than its projected life.In head running, often occur that cam explosion damages, cause maintenance down.

Summary of the invention

The utility model, for solving existing cam in use, also exists join strength low, the problem that cam easily bursts, and provides a kind of join strength large,

The technological scheme that the utility model solves existing issue is: a kind of machine head of embroidery machine cam, comprise for cam body, live axle, connect the annular clamping head of live axle and cam body, as improvement, described annular clamps first end or two ends are provided with shirt rim, and the back side of described cam body and the exterior edge face of shirt rim are connected.

As further improvement, described cam body and corresponding part, clamping head shirt rim are provided with attachment hole.

As further improvement, described clamping head shirt rim is consistent with cam external frame.

As further improvement, described shirt rim is outward extending convex edges, clamping head one or both ends.

The utility model compared with prior art, in the one or both ends of annular clamping head, shirt rim is set, the dorsal surface of exterior edge face, shirt rim and cam body is connected, significantly increase the area of transmission of power, its arm of force is increased, its beneficial effect is in moment of torsion transmittance process, decreases the damage of clamping head to cam, effectively can extend the working life of cam.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model,

Fig. 2 is the structural representation of the utility model clamping head.

Fig. 3 is case study on implementation schematic diagram of the present utility model.

Embodiment

See Fig. 1-3, the implementation case comprise for cam body 1, live axle 2, connect the annular clamping head 3 of live axle 2 and cam body 1, annular clamping head 3 one or both ends are provided with shirt rim, specifically can determine according to single, double cam situation, the back side of cam body 1 and the exterior edge face of shirt rim 31 are connected.Cam body 1 and clamping head 3 shirt rim 31 are by bonding connection.

In the implementation case, cam body 1 and corresponding part, clamping head 3 shirt rim 31 are provided with attachment hole 4, can be screws, connect by bolt or screw.

Clamping head 3 shirt rim 31 is consistent with cam external frame, in the space that head is limited, does not affect the use of cam, the area of maximized increase shirt rim 31, to increase the arm of force, reduces the damage to cam in torsion transmittance process as far as possible.

Shirt rim 31 can be integrated with clamping head, is outward extending convex edges, clamping head 3 one or both ends, or independently arranges and the plate face on clamping head 3.

Cam structure of the present utility model can be used for embroidery machine presser foot lift cam or thread take-up cam.

Claims

1. a machine head of embroidery machine cam, comprise the annular clamping head for the cam body of pressure foot lifting, live axle, connection live axle and cam body, it is characterized in that: described annular clamps the shirt rim that first end or two ends are provided with, and the back side of described cam body and the exterior edge face of shirt rim are connected.

2. machine head of embroidery machine cam as claimed in claim 1, is characterized in that: described cam body and corresponding part, clamping head shirt rim are provided with attachment hole.
