Abstract

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to machine tools. The invention allows to simplify the design. On the base I with the stand 2, there is a clamping element 3, a removable hydraulic actuator 4 with a brush 12, a bore 13 and protrusions 11, a support 5 with a spherical lock 6. The hydraulic actuator 4 is installed into the slots 8 on the upper plane 14 of the clamping element 3. At the same time, the piston rod J2 of the hydraulic actuator 4 interacts with the support 5. The working fluid is supplied to the opening 10 of the hydraulic actuator 4 and it secures part 9 by means of the clamping element 3. The spherical latch 6 moves along the support 5 and interacts with the lower bottom plane 7 Foot member 3 fixes its position. 2 Il.

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to machine tools.

The aim of the invention is to simplify the construction of the niches.

FIG. 1 shows a device during the clamping of workpieces, a general view; in fig. 2 - the same, in a working position, a general view.

The mechanism for fixing the part 9 moves along support 5 up until it touches its spherical surface with the lower plane 7 of the clamping element 3, with the result that the gap between the clamping element 3 and the mechanism 6 for fixing the part 9 is selected. After that, the working fluid is switched to the drain, the spring of the hydraulic actuator 4 returns it to the starting point 13 with the brush 12 to the initial position and the hydraulic actuator 4 has a device for fixing parts. parts 9 in others

devices. In this case, due to the elastic deformation of the clamping element 3, under

element 3, a replaceable hydraulic actuator 4, a support 5 mounted on the base 1 and interacting with the hydraulic actuator 4, and a fixation mechanism 6 with the hydraulic actuator 4 removed, you are J5 with water 4, the workpiece 9 remains retained in the form of a spherical fixator, fixed with force, the value of which is mounted on the support 5 with the possibility of less by 10-15% less force, created by the force generated by the hydraulic displacement and interacting with the lower plane 7 of the clamping element 3. To install the hydraulic actuator 4 on the clamping element 3, the groove 8 is made.

The hydraulic actuator 4 is designed to secure the workpiece 9 and has an I-hole 10 for supplying the working fluid and protrusions 11 for interacting with

hydraulically driven 4. Loss of force associated with the choice of gaps in the connection support 5 - mechanism 6 fixing parts 9 when disabling the hydraulic actuator 4.

To detach the part 9 after machining, the hydraulic actuator 4 by the protrusions 11 is re-inserted into the groove 8 of the clamping element 3 and is fed through the opening 10 under the pressure 14 of the element 3.

The device works as follows.

the mechanism 6 for fixing the part 9 into the groove of the metal-cutting machine or tool (not shown) over the grooves 8 fixed by the posts, and also the rod 12 with the working medium pressure 13. 13. The groove 8 is made on the upper plane - Since the force generated by the hydraulic actuator 4, by 10-15% more effort, with which the workpiece 9 is fixed, the clamping element 3, deforming the world within the limits of elastic deformation, reduces

Having secured the stand 2, and with it the base load acting on the mechanism 6, fixing 1, clamping element 3, support 5 and part 9, to the value sufficient

to move it around the support. A gap is formed between the surface 7 and the mechanism 6 for fixing the part 9. The working fluid, by the top of the workpiece 9, is placed on the drain, and the fixture of the workpiece 9 is dissolved in the groove 8 of the clamping element. 3 The hydraulic actuator by means of its projections 11. When installing the hydraulic actuator 4, the rod 12 of the piston 13 of the hydraulic actuator 4 contacts the support 5. After installation, the working fluid is fed under pressure into the hole 10 of the hydraulic actuator 4. Under the action of a stand, a support, a replaceable hydraulic actuator with

protrusions arranged in grooves and a locking mechanism, characterized in that, in order to simplify the construction, the grooves for the knob 5 raise the right end of the clamping 45 accommodating the projections of the replaceable hydraulic element 3, and the latter turning the water on the upper plane the leg of the stand 2, with its left end of the clamping element, and the locking mechanism - wears the workpiece 9. When locked in place on the support with the possibility of fixing the workpiece 9, it is clear that it is moving and interacting with the deformation This 3 is the bottom plane of the clamping element within the elastic defumations, and between 50 spherical locks, while the support by the clamping element 3 and the mechanism 6 is designed to interact with the pin-clamping and the part 9 forms a gap. A removable hydraulic drive.
