Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Referring to fig. 2 to 3, fig. 2 is a perspective view showing a cam for a textile machine with protection effect according to a preferred embodiment of the present utility model; fig. 3 is an exploded view of a preferred embodiment of a cam for a textile machine having a protective effect according to the present utility model. As shown in fig. 2 to 3, the present utility model provides a cam for a textile machine having a protective effect, comprising: the driven disc 100, the driven disc 100 is used for connecting with the rotating shaft, the center position of the rotating shaft chuck 101 is provided with a shaft hole 104, the shaft hole 104 is composed of a round hole and two rectangular through grooves, and the driven disc 100 is used for stably positioning the rotating shaft. A plurality of trapezoidal limit bars 102 are installed on the side wall of the rotating shaft chuck 101, the width of the trapezoidal limit bars 102 gradually decreases along the direction away from the central position of the cam plate 200, which allows the limit groove 306 to be inserted from a narrow part, and the extrusion force of the side wall of the limit groove 306 and the two sides of the trapezoidal limit bars 102 is continuously increased along with the increase of the insertion depth. The rotary shaft chuck 101 is provided with a plurality of sinking type threaded holes 103, the sinking type threaded holes 103 are used for being connected with bolts when being connected with a cam, the cam can be locked on a rotary shaft, the sinking type threaded holes 103 are formed by threaded through holes and annular grooves, the rotary shaft chuck 101 is fixed at the center of the driven disc 100, the driven disc 100 is provided with two flat plate surfaces, one flat plate surface is a surface opposite to a textile machine, the other flat plate surface is an outer leakage surface, and one end of the rotary shaft is required to be flush with the outer leakage surface.

With continued reference to fig. 2, as shown in fig. 2, three cam plates 200 and driven disc 100 are integrally formed of the same material, and the thickness of cam plate 200 is greater than that of driven disc 100, so as to reduce the weight of the cam while maintaining the original bearing capacity, and the included angles between the central lines of three cam plates 200 on the side wall of driven disc 100 are the same, so that under the condition that the rotating shaft drives the cam to rotate for one turn, cam plate 200 can drive other parts of the textile machine to lift up and down three times.

With continued reference to fig. 3 and with reference to fig. 4, as shown in fig. 3 and 4, in order to solve the problem of dust accumulation and flocculation in the gap between the rotating shaft and the shaft hole 104 on the cam, and in order to prevent the bolt from being excessively screwed, and in order to avoid the rotation of the bolt in place, a protection component 300 is sleeved on the rotating shaft chuck 101 of the outer leakage surface. The following describes the structure of the protection assembly 300, the protection assembly 300 includes a snap ring 301, the snap ring 301 is used to be sleeved on the side wall of the spindle chuck 101, and the snap ring 301 is sleeved on the spindle chuck 101. Specifically, the limiting groove 306 is inserted from a narrow portion, and along with the increase of the insertion depth, the extrusion force of the side wall of the limiting groove 306 and the two sides of the trapezoidal limiting bar 102 is continuously increased until one side surface of the snap ring 301 abuts against the outer leakage surface on the driven disc 100, and the limiting groove 306 corresponding to the trapezoidal limiting bar 102 is formed in the inner wall of the snap ring 301. The inner wall of snap ring 301 is fixed with a plurality of even platform 303, even one side of platform 303 installs prevents moving back gasket 304, prevents moving back gasket 304 and sinking screw hole 103 one-to-one, lets the bolt of installation cam and pivot not direct with sinking screw hole 103 top surface contact, avoids installing the maintenance in-process repeatedly and causes the bolt wearing and tearing because of rotatory excessively, and then has effectively avoided the emergence of the not hard up phenomenon of cam that the bolt wearing and tearing caused. The concentric position of snap ring 301 installs protective cover 302, and protective cover 302's lateral wall and the lateral wall fixed connection of preventing backing gasket 304. When one side of the snap ring 301 abuts against the exposed surface of the driven disc 100, the overhead groove 305 is disposed on one side of the shaft hole 104, and the overhead groove 305 is formed to avoid abutting between the end surface of the rotating shaft and one side surface of the protective cover 302.

In summary, the beneficial effects of the utility model are as follows: through cover setting up protective cover 302 on pivot chuck 101, let form overhead groove 305 between protective cover 302 and the pivot, realized the guard action to installing pivot and shaft hole 104 gap on the cam, the problem of adsorbing the accumulation dirt battle in the gap has been solved, and then the operation degree of difficulty of maintenance cam has been reduced, through fixing the anti-back gasket 304 in one side of snap ring 301, let the bolt of installation cam and pivot not direct with the submerged screw hole 103 top surface contact, avoid the installation maintenance in-process because of rotatory excessively causing bolt wearing and tearing, and then effectively avoid the emergence of the not hard up phenomenon of cam that the bolt wearing and tearing caused, the stability of cam assembly in-process has been strengthened, through letting anti-back gasket 304 pass through spacing groove 306 and trapezoidal spacing 102 limit position, realize the effect of gasket position locking, effectively avoid appearing the gyration phenomenon between the bolt of installation in place and the gasket, strengthen the firm degree of bolt installation.
