Description

one

The invention relates to the tire industry and can be used in the manufacture of chambers for the roughing of rubber valve flanges.

The purpose of the invention is to improve the quality of roughness and ease of operation.

FIG. 1 shows a machine, a general view; FIG. 2 is a section A-A in FIG. one; in fig. 3 is a diagram of the machine sub-adjustment.

The machine contains a rough tool mounted on the bed 1 - a brush 2 with its rotation drive from a direct current electric motor, table 3, mounted on the rod 4 of the power cylinder 5.

On the table 3, rotational from the electric motor 6 is mounted through a V-belt drive 7, a gearbox 8 and a gear drive 9, a disk 10 with spindles 11 arranged on it with sockets for valve installation and pushers 12 interacting with a lifting cam 13 fixed on table 3.

Turning the disk 10 is installed on the end of the vertical drive shaft 14 through universal joint 15 and two horizontal diametrically located on the table 3 rollers 16, and the X and X / supporting rollers 16, the axis of the hinge 15 and the surface 17 of the spindles of the spindles . The disk 10 is provided with an annular cam 18 with slots 19 for engaging a roller 20 fixed on a fixed stop 21, and a roller 22 fixed on a movable spring-loaded spring 23 stop 24, which are mounted on a table 3. The force of the spring 23 is adjusted by a handwheel 25.

The movable stop 24 through the TU 26, the spring 27 is connected with the valve 28 controlling the power cylinder 5.

On the base 1 there is a mechanism 29 for controlling the frequency of rotation of the brush 2, for example, in the form of a selsyn sensor, on the shaft of which a lever 30 is fixed to interact with the fork. Koy-stop 31, mounted on the table -3.

The machine works as follows.

The rotational drive of the hierus is turned on and the rotational drive

 Floor 10, a distribution valve 32 is opened to supply the medium to the power cylinder 5.

In the loading zone, valves 33 are inserted into the spinda5 levers 11, which periodically move, alternately take up the work space under the squirrel brush 2. At the beginning of the rotation of the disk 10 around the vertical axis, the roller 20 interacts with the cam 18. spindle 11, which is at this time., under brush 2, from it by turning the disk 10 around the horizontal axis XyX j,

15 and at the end of the rotation around the vertical axis the roller 20, falls into the groove 19, made on the cam 18, releases the disk 10, and it is loaded by the force of the spring-loaded stop 24 through the roller 22

20 presses the spindle 11 with the valve 33 to the brush 2.

The flange of the valve is roughened.

In the process of turning the disk 10 around the vertical axis, the scratched valves 33, which interact with the lifting cam 13, are pulled out of the spindle jacks and assembled into a container (not shown) along the slide tray.

Initial adjustment of the machine for high-quality roughing is carried out by adjusting the force of pressing the spindle 11 to the brush 2 by the spring 23 and

5 times the valve is in the working area by changing the speed of the disk rotation drive 10.

The additional adjustment of the machine during operation is shown in the diagram (Fig. 3), where D is the initial diameter of the brush; D (is the reduced diameter IHCTKH due to normal wear and tear; os is the angle of rotation of the disk around the axis X-Y-X;

 on which it is necessary to bring the table closer to the brush so that it occupies the initial position (about 0); n is the number of revolutions of the brush before the adjustment; n is the number of revolutions of the brush after adjustment, and is carried out as follows.

As the scrubbing brush 2 is worn from diameter D to D. The disk 10, which is initially in position I,

5, under the action of a spring-loaded stop 24, which presses the spindle 11 with the valve to the brush 2, rotates around the axis X-Y-X;

and takes the position of 1G. In this case, the stop 24 through the pull 26, the spring 27 acts on the valve 28 controlling the power cylinder 5, which, having opened, releases the access of the working medium to the cavity a of the cylinder 5.

Table 3 is lifted by the value of h, and the disk 10, turning back, occupies position III (oi 0). The valve 28 is closed, the hydraulic access to the cylinder 5 is stopped.

At the same time during the lifting of the table 3, the fork-stop 31 rotates the lever 30 mounted on the boom shaft

The syn sensor 29, at an angle, the selsyn sensor gives a signal to the corresponding magnitude of the brush revolutions up to the veltgchina p ,,, to maintain an equal speed of E1;

during the whole service life of the brush, the cycles of the smooth adjustment of the machine during its operation are repeated. The return of the table 3 to the lower position is effected under its own weight with the valve 28 open.
