Description

I

The invention relates to mechanical engineering, in particular to the machine tool industry, and is used in automatic machines for feeding parts from a container into a work area.

A device for feeding parts is known, comprising a base with parts container mounted on it, a clamping device, a feeder with sockets which are provided with a clamping element, and an actuator Ull.

The disadvantage of such a device is that the pressure plate due to differences in dimensions within the tolerance does not ensure reliable fixing of all the details at the same time.

The purpose of the invention is the elimination of axial displacement of parts during their transportation to the working area in a multi-seat device.

The goal is achieved by the fact that the clamping elements are made in

The form of spring-loaded sliders with profiled slats, and the base and clamping device are equipped with pins that interact with the profile bars of the clamping elements.

 FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 section bb in fig. 2; in fig. L 10 view B in FIG. 3; in fig. 5 is a section of YYD in FIG. four.

The device for feeding parts consists of a base 1, on which a container 2 with parts 3 and

t $ with a cutter 4 ,, clamping device 5 having upper 7 that are movable from hydraulic cylinders 6 and fixed 8 lower prisms equipped with pins 9.

In the vertical guides 10 of the base 1, the table P moves from the hydraulic cylinder 12. In addition, on the base 1, brackets 13 with pins 9, similar to the pins of fixed prisms 8, are rigidly fixed.

The feeder 14 is in the form of a carriage with sockets 15, connected to the hydraulic cylinder I6 and horizontally moving in the direction of the upper table 11, and clamping elements embedded in the form of sliders 17 with springs 18 are embedded on which the profiled strips 19 are fixed on the side.

The proposed device works as follows.

With prisms 7 and 8 open, hydraulic cylinder 12 moves the table vertically upwards. 11 along the directions 10 of the stationary base 1, and through the slots 15 of the pyatel 14, the parts 3 fed from the tank 3 of the shutter 4 are captured.

The feeder 14 is moved horizontally to the left by the hydraulic cylinder 16 to the working position, and the hydraulic cylinder 12 lowers the table 11 together with the feeder 14 and the hydraulic cylinder 16, positioning the fed parts 3 onto the fixed pins 8 of the fixture 5. The treated parts 3 roll into the container. Thereafter, the feeder 14 returns to the right to the initial position by the hydraulic cylinder 16, and the feed parts 3 are fixed for processing by the movable prisms 7 driven by the hydraulic cylinders

During transport, the parts 3 lie in the slots 15 of the feeder 14, pressed by the sliders 17, whose sequence of operation is determined by the interaction of the surface P of the LVSRE in FIG. 5) profiled Gshank 19 with pins 9 brackets 13 and the lower fixed prisms 8.

At the beginning of the lifting of the table 11, the pins 9 of the brackets 13 retract the slide blocks 1 7 to the right {the LVSRE section in FIG. five),

compressing the spring 18 and seizing the part 3. With the further raising of the table 11, the slide blocks 17 under the influence of the springs 18 move the lley section of the DE in FIG. 5) and fix the details 3.

After transferring the workpieces 3 by the feeder 14 to the working position when the table is lowered 11, the profiled plaques 19, interacting with their surface P with pins 9 mounted on the fixed prisms 8 of the clamping device 5, discharge the slide blocks 17 and release the parts 3,

The use of the proposed device in a special boring machine model 008-812 completely eliminates the axial movement of parts when transferring them to the work area, improves the quality of manufactured products and working conditions, and provides multi-maintenance.
