The invention relates to mechanical engineering, in particular, to clamping devices of the clamping type for mounting and clamping parts of complex forviol with untreated, spatially located end surfaces, and can be used, for example, in turbine construction in the machining of steam turbine blanks. on grinding machines.

The aim of the invention is the expansion of technological capabilities by ensuring reliable fixation of products on end surfaces with a complex configuration at any spatial location relative to the basic supporting elements.

FIG. 1 shows the device, a general front view; FIG. 2 is the same, top view, in FIG. 3 - view A on. FIG. 1, in FIG. 4 is a view B in FIG. 1; in fig. 5 is a view of B in FIG. 1j in FIG. 6 - section GG in FIG. 2; FIG. 7 - section DD in FIG. 2

The device for clamping products contains a base 1, a housing 2 mounted on it, jaws 3 and 4 fixed on it and basic support elements 5. On the jaws 3 and 4 of the device, the pads 6 and 7 are rigidly fixed with clamps 8 and 9. Clamps 8 and 9 are made with holes 10 in which: stops 11 are installed with working beveled surfaces 12 and sharp edges. The stops 11 mounted on the movable jaw 3 are rigidly connected with their clamps 8 and fixed in the axial direction. The stationary sponge 4 is provided with only one stop 11, which is provided with a guide rail 13 and is installed in the clamp 9 along a movable fit for movement in the axial direction. For this purpose, a spring 14 and a stop screw 15 are installed in the clamp 9, acting on the guide along the juice 13 of the stop 11 s. two opposite sides. To eliminate the reversal of the lugs 11 around their own axis, fixing screws 16 are installed in all clamps 8 and 9.

The device is equipped with a rocking chair 17 installed on the sponge 3 on the axis 18,

The plate 6 is mounted on the rocking chair 17. The rocking chair 17 and the sponge 4 are made with straight T-shaped grooves arranged parallel to the base 1,

and the plates 6 and 7 are installed in them with the possibility of their movement along the grooves manually and with subsequent fixation with the help of screws 18,

Screws 19 and 20 are provided for fixing the clamps 8 and 9 in a vertical position,

To install the basic support elements 5 in the position corresponding to the location of the support surface of the article to be treated 21, in the housing 2 there are made straight grooves 22 arranged parallel to the base 1,

The installation and clamping of the workpiece in the device is carried out as follows,

When the jaws 3 and 4 are divorced together, adjustable base support elements 5 are brought to the lower support surface of the product 21. By adjusting them in height and displacing along the grooves 22 in the housing 2, they make preliminary contact of the product 21 on the end with the stop 11 on the sponge 4. Then by moving the pads 6 and 7 along the T-shaped grooves and the clamps 8 and 9 themselves in the vertical direction and the angular rotation of the rocker 17 on the axis 18 ensure the contact of the stops 11 with the end surfaces of the workpiece 21,

After checking the correctness of the contact of the lugs 11 with the end surfaces of the product 21, the plates 6 and 7 are fixed with clamping screws 18.

To fix the product 21 in the device, the jaws 3 and 4 are brought closer by means of a power drive 23, ensuring the insertion of sharp-pointed lugs of the stops 11 into the body of the product 21. At the same time, not only is the latter secured, but also pressed, to the basic support elements 5. on the sponge 4 spring-loaded allows you to hold the clamping force within the specified limits.

Due to such a constructive implementation, the technological capabilities of the device are significantly expanded, since it ensures reliable closure of various sizes of products on the end surfaces of a complex configuration. This reduces the auxiliary time for readjustment of the device when changing the sizes of the product.
