Abstract
The invention discloses an end face cam for a spherical groove. The end face cam comprises a circular disk base, wherein a cam is arranged in the middle of the circular disk base; a spherical groove of which the profile is the same as that of the cam is arranged between the cam and the circumference of the circular disk base; a ball is arranged in the spherical groove; an installing hole is formed in the center of the cam; the circumferential surface of the circular disk base is provided with a synchronous belt groove; and the ball is provided with a connecting hole. The end face cam for the spherical groove has the advantages of long service life, convenience in installing, detaching and maintaining, low maintaining cost, stable working effect, increase in the production efficiency and improvement on the product quality.
Description
Technical field
The present invention relates to the Sewing machines field, relate in particular to a kind of spherical groove edge cam.
Background technology
The movement locus of sewing machine needle is normally controlled by the cam that is arranged on the Sewing machines.Its operation principle is that cam sends motion mode to the eedle frame by connecting rod, controls swinging up and down of eedle.Fixedly connected by crank between general Sewing machines and the cam, by the motion of crank drivening rod, come the controller needle movement during cam rotation.This connected mode installation and removal rate of exchange trouble, and fragile, the inconvenience maintenance.
Summary of the invention
Technical problem to be solved by this invention is that a kind of convenient spherical groove edge cam of installing, dismantling and keep in repair is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of spherical groove edge cam, comprise disc seat, be provided with cam in the middle of the described disc seat, be provided with the profile spherical groove identical between cam and the disc seat circumference with cam, be provided with ball in the described spherical groove, cam center is provided with installing hole, and the disc seat periphery is provided with synchronous trough of belt.
Preferably, described ball is provided with connecting hole.
Compared with prior art, usefulness of the present invention is: this spherical groove edge cam long service life, and be convenient to install, dismantle and maintenance, and maintenance cost is low, the work effect stability has improved production efficiency and product quality.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of spherical groove edge cam of the present invention structural representation.
Among the figure: 1, disc seat; 2, cam; 3, spherical groove; 4, synchronous trough of belt; 5, installing hole;
6, ball; 7, connecting hole.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of spherical groove edge cam shown in Figure 1, comprise disc seat 1, be provided with cam 2 in the middle of the described disc seat 1, be provided with the identical spherical groove 3 of profile and cam 2 between cam 2 and disc seat 1 circumference, be provided with ball 6 in the described spherical groove 3, cam 2 centers are provided with installing hole 5, and disc seat 1 periphery is provided with synchronous trough of belt 4; For the ease of movement effects is passed, described ball 6 is provided with the connecting hole 7 that is used for connecting crank.
This spherical groove edge cam long service life is convenient to install, dismantles and maintenance, and maintenance cost is low, and the work effect stability has improved production efficiency and product quality.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
