Abstract

The CLAMP of the DEVICES, the casing of which has a support, and FIG. the ability to rotate relative to an axis in the housing of a spring-loaded tack, characterized in that, in order to expand technological capabilities by providing clamping workpieces with high walls, the housing is made in the form of racks with horizontal grooves, and the device is equipped with an additional axis that is installed with the possibility of movement and adjustment in grooves, while the tack is located with the possibility of free rotation between the axles and is spring-loaded relative to the support.

Description

The invention relates to mechanical engineering and can be used in tooling machine tools, for example, for clamping parts with high walls. The purpose of the invention is the expansion of technological capabilities by providing clamping blanks with high walls. FIG. 1 shows the clamping device, bat, i view; in fig. 2 - the same (in the off position); in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 is a section of GGD in FIG. 2. The clamping device consists of a housing made in the form of a base 1 and two racks 2 on which a support is mounted. On racks 2 there are two axes 4 and 5, which play the role of stops, at a distance C from each other. Moreover, axis 4 is installed in horizontal grooves of the legs 2, and size C is adjusted by displacing axis 4 by bolts 6. Between axes 4 and 5 is clamp 7. In support 3 and in clamp 7 axes 8 and 9 are rigidly fixed, between which are tensioned two tension springs 10. In the non-working position of the sticking (Fig. 2), the axis of the spring 10 is to the left of the contact line of the sticking 7 and axis 5, and in the working position to the right of this line. In the tack 7, there is a threaded hole in which the bolt I moves, having a pressure pin 12. In the tack 7, there is a blind groove 13 (FIG. 4), which includes the support 3 when the working position is stuck. Reference numerals 14 and 15 designate the support plates on which the clamping part 16 is mounted. The angle of inclination a. (Fig. 2) depends on the size C (Fig. 1). At C h, this angle will be equal to 90 °. The clamping device works in the following way. The part 16 is mounted on the support plates 14 and 15, the sticking is in the non-working position (Fig. 2). The springs 10, squeezing, press the clamp 7 to the washers 5 and 4 and hold it in a fixed position. After mounting the part 16 onto the supports 14 and 15, the clamp 7 turns downward, resting on the axis 4. In this case, the springs 10 are first stretched, and after passing the line connecting the axes 5 and 8, lowering the right end of the clamp with the pressure bolt 11 downward . The left end tack 7 slides on the support 3 and is fixed by a groove on this support (Fig. 1 and 4) due to the forces of the springs. By turning the bolt 11, the workpiece 16 is secured. The clamping device in the off position is shown as follows. By turning the bolt 11 by 1 -1.5 turns, the clamp of the part is loosened, then the clamp is held, oh is moved in the direction of the arrow K (Fig. 1) until the clamp is moved from the support 3. Then the right end of the stop is turned upwards. In this case, the upper sticking plane rests on the axis 5, and the spring 10 is extended. After the axis of the springs 10 passes through the line passing through the axis 8 and the line of contact of the sticking 7 with the axis 5, the springs begin to compress, turning the holder to the axis 4, fixing it in this position.
