Description

The invention relates to a machine tool. And can be used for processing parts such as liners with automated installation and removal.

The purpose of the invention is to expand the technological capabilities by providing machining of holes in lengthy parts and simplifying the design of the device.

Fig. 1 shows the mounting-clamping device in the position of mounting the part on the prisms of the pre-base; figure 2 - the same, with clamped in the base sleeves detail; on fig.Z - section aa in figure 1; figure 4 - section B-Bnafig.2; on FIG. 3 — section BB — in FIG. 1; 6 — section G-D in FIG. 2.

The mounting-clamping fixtures consist of a fixed stand 2 and a movable clamping head 3 fixed on the base 1 of the machine and equipped with clamping elements made in the form of sleeves 4 and 5. The sleeves have conical holes 6 for basing parts 7 on them during clamping cm, figure 1).

The first prism 8 of the pre-basement is fixed on the clamping headstock 3, the supporting surface of which is made in the form of rollers. The prism 8 is equipped with an adjustable length stop 9. At the same time, the GO axis of the bearing surface of the prism 8 is located below the axis 11 of the clamping sleeves 4 and 5 by an amount of 6 J, which allows the part 7 to fit over the prism 8 at the time of its clamping in the sleeves (see FIG. W and 6).

Second prism 12 pre

The base is mounted on the fastened up to the holes in the lengthy parts

Nom on frame 1 hinge 13 and at the same time performs the function of a base ejector. In this case, the axis 14 of its basement is located above the axis 13 of the clamping sleeves 4 and 3 45 by an amount p, which ensures the output of part 7 from the base sleeve 4 of the fixed stand 2 (see FIG. 3 and 4).

The prism 12, on the one hand, is limited by a rigid stop 16 with an adjustable length, and on the other hand, it constantly interacts with an equipped 18 elastic element 17, the force of which is greater than the weight of the workpiece.

The clamping fixture works in a dim way.

The workpiece 7 is mounted on the prisms 8 and 12 of the preliminary base. In this case, the part occupies an inclined position to the axis 11 of the base sleeves 4 and 3.

Then, the clamping headstock 3, together with the prism 8, is moved to the left, as a result of which the stop 9 interacts with the prism 12, which, compressing the spring-loaded stop 18, turns on

20 angle, allowing the part 7 to enter the conical holes 6 of the sleeves 4 and 3, and with further movement of the clamping head 3, detach from the bearing surfaces of the prisms 8 and 12 and self-align 25 seconds into the Conical holes x 6 with subsequent fixation (see Fig. 2 ).

After finishing the machining of the part, the clamping headstock 3 is retracted to the right to the initial position and the stop 9 releases 30 a prism 12, which under the action of the spring-loaded stop 18 begins to return to the initial position, lift the part 7 and move it along the rollers of the prism 8. Thus, the part in the original position.

The proposed technical solution allows to expand the technological capabilities, namely, to process 35

liner types, by removing the central hole in the fixed rack, which is necessary for large amounts of chips and coolant from the treatment area, as well as simplify the design of the device by eliminating the function of the pusher of an individual drive from the prism.
