CS226579B1 - Movable jaw guides especially for clamping devices - Google Patents

Abstract

The invention solves the shape of the guide surfaces of the movable jaws, enabling their quick replacement. By using the guide of the movable jaws according to the invention, the construction of the clamping device is simplified, while the possibility of quick replacement of the movable jaws is maintained. An additional control device is not required to release them from engagement with a fixed frequency, as the movement required to derive the power lift of the jaws is used for this.

Description

226579 2

The invention differs in the shape of the guiding surfaces of the movable dies allowing their rapid replacement. In the hitherto known constructions, in particular interchangeable clamping devices, they are discharged from the Selascruiser, the guide surfaces are formed over the entire length of the movable cones. Their release from engagement with the body of the clamping device for rapid replacement is accomplished by means of a circular guide forming a lock.

A disadvantage of such a solution is that a further control device for opening and closing the murmur lock as well as a relatively complicated construction of the clamping device itself and the rigid guide are needed to check the clamping device with the guides thus designed.

The above disadvantages are alleviated by the guiding of the movable ducts, especially for the clamping devices according to the invention, the principle of which is that the rigid duct is formed by at least one notch or notch and the movable duct is formed by at least one projection and recess, while cutout guide.

By using the guides of the movable dies according to the invention, the construction of the clamping device is simplified, while the possibility of a quick exchange of the movable ducts is maintained. An additional control device is not required for releasing from the engagement with the fixed shaft, since the movement required to draw the force stroke is used for this purpose.

In the accompanying drawings, an exemplary embodiment of the invention is shown, e.g. with a quadrilateral cross section of the conduit. In Figures 1a to 1g, the individual portions shown are separated from the meshing. In Figures 2a and 2b, the movable Saxon is shown in a rigid portion, for example. Figures 3a and 3b show the position of the let-off allowing their exchange from Sela. FIG. Figures 4a and 4b show the movements in the force stroke release and release. The guiding of the movable part consists of a fixed part 10 and a movable part 0. In a fixed guide 11 of known shape, for example, rectangular dovetails, circular and subdivided projections 111 and notches 112 so as to form a notch 113 in the fixed conduit 11 in a similar manner. Fig. 211 and recesses 212. Figs. 1 illustrate two embodiments of a conduit, in which Figs. 1a to 1d are provided with grooves 213 for engagement with projections 111 of a fixed conduit 11. In the embodiment of Figs. 213.

The movable SeTust 20 engages the force element 30 of the clamping device in a known manner.

Upon clamping, the SeTust 20 is movable by means of its projections 211 with a section 112 of the rigid fastener 10, the projections 211 being substantially a recess 111 of the rigid guide 11 (FIGS. 2a, 2b). Sast £ uses their total stroke on the power stroke of the movable thrusts (Fig. 4a, 4b). Upon releasing the movable engagement engagement with the rigid body 10 behind its replacement, the movable SeTust Q moves to a position where its protrusions 211 are opposed to the notches 112 of the rigid guide 11 and opposite the protrusions 111 of the rigid guide 11 relative to the recesses 212 of the movable guide 21. utilizing the Saxon of the total stroke is about 6 (FIGS. 4a, 4b). The length of the projection 211 and the cut-out 112 are the same, therefore, the movable SeT 20 can be removed from the fixed port. When inserting the movable SeT 20 in the fixed Sast 10, the procedure is the opposite. The length of the projection 211 is further selected to be equal to the total stroke of the movable face 20. In this way, all the functions of the movable face 20; i.e., clamping and changing, and providing one and the same control device.

The guidance of the invention can also be made for a different shape of guide rails, e.g., fish-new, cylindrical and the like.
