Description

This invention relates to metal working and can be used to clamp a part in two mutually perpendicular planes.

The purpose of the invention is to increase the reliability of fixing parts by using an additional elastic clamping element mounted eccentrically relative to the column.

FIG. 1 shows the proposed device; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one.

The device includes a housing 1, support strips 2 and 3 for mounting and positioning the part 4, a column 5 on which a movable rotary clamp 6 is mounted with the holder 7, spring-loaded at the bottom 8.

The column in the upper part ends with a threaded section on which the nut 9 is screwed, designed to move the grip 6 along the axis of the column 5 and fix the part on top.

In the middle part of the column 5, an additional clamping element 10, made in the form of two elastic rings 11 and 12 interconnected, is located one inside the other eccentrically relative to each other. The inner ring 11 is inserted into an annular groove 13, formed on the column 5 and securing the additional clamping element 10 from displacement along the axis of the column. The outer ring 12 encircles the sleeve 7 of the tack 6, and the connecting element 14 connecting the rings 11 and 12 passes through the groove 15 cut in the holder 7 along its axis.

The device works as follows.

The part 4 is mounted on the strip 2 of the housing 1 and brought up to the stop in the strip 3. The tack 6 is rotated from the initial position (shown by dash-dotted lines) towards the part 4. When turning the sticking side, the corresponding wall of the groove 15 of the yoke 7 acts on the connecting element 14, and the additional clamping element 10 is also rotated together with the claw, and its inner ring 11 rotates in the annular groove 13 around the column 5, and the ring 12, eccentrically located relative to the ring 11, meets

with part 4 and, interacting with it, it is compressed and presses the part to the plank 3 by the force of its elasticity. After turning the claw 6 to the required working position, rotate the nut 9, as a result of which the clamp 6 moves down along the axis of the column 5 and clamps the part from above, squeezing a few spring 8.

When the clamp 6 moves along with the yoke 7, the groove 15 moves downward, while the connecting element 14 passing through the groove 15 remains stationary together with the rings 11 and 12 (since the ring 11 is in the groove 13 of the column 5) relative to the column 5 and parts 4 and does not interfere with the movement of the grip 6. The ring 12 constantly presses the part 4 to the strips 2, ensuring that the part is basing its clamping by the clamp 6 due to the elasticity of the ring 12, the errors in the manufacture of the part 4 of the device are compensated for, the column 5 bending.

To loosen the part 4, the nut 9 is unscrewed, while the clamp 6 with the yoke 7 and the groove 15 is moved upwards by the action of the pin 8 and the additional clamping element 10 remains in place. Then turn tack 6 to the original. the position, with the corresponding wall of the groove 15 acting on the connecting element 14, the additional clamping element 10 is also rotated together with the clamp 6 to the initial position and the ring 12 releases the part.

The proposed device can be used for clamping several parts, mounted on one another (for example, for drilling holes in several parts at the same time). To do this, additional clamping elements are installed against each part.

The device can be equipped with a set of interchangeable additional clamping elements, different in diameter of the outer rings and serving for clamping parts of various sizes, eliminating damage to the parts with an additional clamping element when clamping parts, while expanding the technological possibilities of using the device, securing the parts.
