FIG. /; F

. Part of the pins is lowered, compressing the springs until the weight of the workpiece is balanced by the elastic force of the springs. Then the magnets are turned on, their core is pulled in, releasing the rods 6, which are pressed against the pin, rigidly fixing them in the holes. Then they raise an additional base and perform all the same operations on it. As a result, additional pins are pressed against the workpiece, which is securely fixed and in which the side surfaces can be machined. 6 Il.

The invention relates to ancillary equipment and can be used in metalworking and in flexible production systems to reduce the material and time spent on retooling workpiece positioning devices before machining.

Known tunable container, containing the base with holes arranged in rows at equal intervals, and placed in the holes of the rack, additional holes are made in the base, intersecting each row of core, the stands are designed as spring-loaded pins the holes are spring-loaded to the pins and covered with elastic material by the rods to interact with the pins of the corresponding row, and at the base there are two holes for fixing the container in a predetermined position NII.

The disadvantage of this device is that it cannot provide rigid automatic fixation of blanks located in the container during their machining. Therefore, it cannot be used in the machining of workpieces and it is necessary to introduce new positioning devices in the FMS,

The purpose of the invention is the expansion of operational capabilities.

This goal is achieved by adjusting the container containing the base with openings arranged in rows at equal intervals and additional openings intersecting each row of core, two openings for fixing the container in a predetermined position, placed in the last uprights in the form of spring-loaded along the axis of the pins, mounted in the additional holes, spring-loaded to the pins and covered with elastic material, rods for interaction with the pins of the corresponding row are provided with identical additional base with additional pins and rods facing the base and a hydraulic cylinder with a piston with a rod placed in it, a hydraulic cylinder body

placed on the main base, and the end of the rod is fixed on the additional base facing the main end.

Figure 1 shows a general view of the container; figure 2 - the container at the time of readjustment (the main basis); on fig.Z - the moment of fixation of one of the pins; figure 4 - the container at the time of readjustment (additional base); figure 5 - cylinder; figure 6 - the container is fixed in the product.

The tunable container contains a base 1 with openings 2 arranged in rows at equal intervals, placed in the openings 2 racks made in the form of axially spring-loaded using

springs 3 pins A, additional openings 5 in the base 1, intersecting each row of main 2. Additional 5 holes are installed spring-loaded to pin m 4 and covered

elastic material rods b for engagement with pins 4 of a corresponding row. The base 1 is also made fixing holes 7. The container contains a hydraulic cylinder with a piston with a rod. Building 8

the cylinder is placed in the base 1, and at the end of the rod 9 is fixed an additional base 10, made identical to the main 1, the additional pins 11 of which are facing the pins m 4 of the base 1.

Tunable container works as follows.

The base 1 is fixed on the table (not shown) with the help of

table pins (not shown) that are installed in the fixing hole 7. On the table also set the electromagnets 12, each having a return spring (not shown) and a measles 13 with an end face in the form of an inclined plane (figure 2). Electromagnets 12 are installed in pairs with the possibility of interaction of Korea 13 with the ends of 14

rods 6 and the possibility of their joint inclusion.

Electromagnets 15 (FIG. 4) are mounted on an additional base 10 and each also has a return spring (not shown) and a bark 16 with an end face in the form of an inclined plane. The electromagnets 15 are also installed in pairs with the possibility of the interaction of Korea 16 with the ends of 17 additional rods 18 and the possibility of their joint inclusion,

The fixing cycle of the workpiece 19 (Fig. 6) before its metalworking is as follows. The additional base 10 turns to the side with respect to the base 1. The electromagnets 12 are turned off, their core 13 under the action of the return springs are set to the upper position, the beveled ends of the bark 13 interact with the ends 14 of the rods 6. The latter depart from the rows of pins 4 which are able to move freely in the holes 2 (Fig. 1). Then, a blank 19 of complex shape is placed on the pins 4.

Under the weight of the workpiece 19, a portion of the pins 4 (depending on the shape of the workpiece 19) is lowered, compressing the spring 3 until the weight of the workpiece 19 is balanced by the elastic force of the spring 3.

After that, the magnets 12 are turned on and their core 13 is retracted, releasing the rods 6. The latter, being spring-loaded, are pressed against the pin m 4, rigidly fixing them in the holes 2.

Then the additional base 10 is raised. In this case, the piston with the rod 9 of the hydraulic cylinder is moved. The working fluid (liquid or gas) freely exits the hole 20 and enters the hole 21. After this, the additional base 10 is deployed, mounted above the base 1, and lowered from above onto the workpiece 19 already installed on the base 1. At the same time, the electromagnets 15 are disconnected, their core t6 is ejected under the action of return springs. 8 the result is the beveled ends of the cores 16, interacting with the ends 17 of the additional rods 18, ensure their displacement relative to the additional pins 11,

which can freely move in the openings 22 of the additional base 10 (fig. h and 4).

After the additional base 10 is lowered onto the workpiece 19, some additional pins 11 located above the workpiece are displaced by the weight of the additional base 10 to the holes 22. This displacement will occur until the weight of the additional base 10 is balanced by the elastic force of the compressed springs 23.

After that, the magnets 15 are turned on and their core 16 is retracted, releasing additional rods 18. The latter, being spring-loaded, are pressed against the additional pins 11, rigidly fixing them in the holes 22.

Then in the hole 20 is supplied working

the body, creating pressure over the piston of the hydraulic cylinder, and the additional base 10 with additional force is pressed against the workpiece 19. The working fluid under the piston is forced out through the opening 21. Springs

24 and 25 do not allow the piston to close the holes 20 and 21 (figure 5).

Thus, at the end of this cycle, a rigid fixation of the workpiece 19 is ensured, in which it is possible to carry out mechanical processing (Fig. 6) of the side surfaces.

It should be noted that the proposed device allows quick fixing of various blanks having

different shape.
