Description

This invention relates to mecanic. the processing of materials, in particular, to the equipment of the central processing unit for fastening tsetals of the type parovyk and gas turbines. A device for installing and fixing cetapes, a social housing, a colored support with a priest and two basic units, of which the LI axially screwed in the axial direction, is known. However, this device is characterized by an insufficiently high machining accuracy, due to the inability of the force to regulate the pressing force on the part. The aim of the invention is to increase the machining accuracy. This goal is achieved by the fact that, in a device comprising a housing, a driven support with a drive and two basic links, one of which is movable in the axial direction, the support is provided in the form of a slide with an insert installed done

bore in the slider, and connected with a wedge drive, with the wedge surface on the insert wedge at an angle of 8-20 ° to the direction of movement of the wedge, and at an angle of 20-30 to the direction of movement of the popun, and rotatable relative to the device and designed to interact with the insert .35

Such an embodiment of the device provides an increase in the accuracy of machining parts by the possibility of adjusting the pressing force of the part by the supplied support .. 40

FIG. 1 shows a general view of the device; in fig. 2 - the same, vip. above} in FIG. 3 is a section A-A in FIG. 1.

The device is installed and secured parts, 1 turbine-type turbine blades, 45 content units co-axially located in housing 1 are two basic units — base cent: 2 II 3, one of which, center 3, is movable in the axial direction of the scientific research institute and connected to the hydraulic cylinder 4 On -JQ housing 1 between the base centers 2 K 3 is installed with the possibility of straight-line movement along the npin myron direction by means of a direct bearing, made in the form of a slider 5 .. gg

Made in the form of dolzun-5 sub-. Zimma support is provided with a wedge surface A and a half-way in the up-model

The breather 9 has an arc apaz f in which the locking screw U is located, which is screwed into the slider 5,

Between the housing 1 and the slider 5 are installed the compression clamp 11, designed to retract the slide 5 from the part 8 during loading.

The device for installing and securing parts works as follows.

Part 8, for example, a turbine blade equipped with two center holes

 at the ends of the tail and the boss, is mounted on center 2 and fixed by center 3 by supplying oil to the headless cavity of the hydraulic cylinder 4. Fixing & part 8 to two centers 2 and 3 deprives / of its five degrees of freedom; only the position of the part 8 along one degree of freedom, namely in the direction of rotation around the C axis of centers, remains uncertain. In order to base part 8 on this degree of freedom, it is necessary to feed oil into the rodless cavity of the hydraulic cylinder 7, as a result of which the wedge 6 moves in the axial direction, and since it is in interaction with the wedge surface d of popun 5, the latter moves upward until until points a and b resist the base radial surface of the blade of the blade 8, due to the fact that

- the aforementioned points a and b are located VSH1 with a wedge 6.1 installed in the housing 1 with the possibility of rotation and reciprocating post-departure movement along the normal to the direction of movement of the cylinder 5 under the action of the drive of the supplied support of the hydrocigade 7. At the same time, the wedge surface d Depending on the operating conditions, the popula 5 may be inclined to the direction of movement of the wedge 6 at an angle aS 8-20, and with the direction of the displacement w / slider p it makes an angle 20 - 30, the apex of which is directed towards the part 8, and the angles Oi and choose Thus, 4To6i i had no effect of self-braking. The support supports the detail 8c, two points a and b (Fig. 3), located on opposite sides of the axis from centers 2 and 3. In slide 5, a hole e is made into which the insert 9 is installed with the possibility of commissioning adjustment. surface d is in interaction with the wedge 6, with the opposite sides of the axis from the centers, the lighting of the cetapy 8 in the device is uniquely defined. This means that the kg surface, d Slider 5, is inclined to the direction of movement of the wedge 6 by the Pots oi. 8-20, and with the direction of movement of the slider 5 it makes an angle of 20-30 °, the apex of which is directed towards the part 8; in the process of moving the slider 5 to the detail 8, the pop-up 5 is pressed by the wedge 6 to the dimensions of the {fig. 2 and 3) of the housing 1, the gaps in conjugation of the slider .5 with the housing 1 are selected. At the same time, a constant pressing of the slider 5 to part 8 during the machining process of the latter is ensured and the removal of the slider 5 is eliminated by the action of cutting forces. In order to allow machining of blades with different tslin and, therefore, 10 624 jjaaniwHjno rigidity in a direction that is perpendicular to their axis, it is possible to adjust the force of the part 8 with the support of 5 chuck with an angle of 3, which is achieved by turning the insert 9, followed by fixing it with the BINT 10. As the wedge 6 is installed in the housing 1 can be rotated, the pH is self-adjusting sp cnrnrnr of the new section of the liner 9. Bottom oil is supplied in shto- kovye gidrotsilintsrov cavity 4 and 7, whereby the center 3 is retracted, and the support portion 5 is lowered podvod1sha shmuck tsep.stviem-springs 11 do not interfere with downstream oo-Tsey loading .. By such vypoptosch; - USP-g about -. The accuracy of the parts is increased by providing an opportunity to regulate the pressure force to the part of the supplied support.
