Abstract

At a modular grip device that is used for erection unit, be provided with a base plate that extends along the x-y plane and at least one can be fixed on the clamping element on the optional position on the base plate.Have the protrusion that on the x-y plane, clocklike is net distribution on the base plate, the datum level that works along the z direction is all arranged on each protrusion.Between protrusion and clamping element, connector can be set as required.Distance between the datum level of the distance between the datum level of neighboring projection thing and a protrusion or equal or become even-multiple.Thus for modular clamping device provides high-adaptability, reliable clamping, simple simultaneously.

Description

The unit type device that is used for clamping element

The present invention relates to a kind of unit type device that is used for workpiece maintenance, clamping and/or location, preferably be used on the machine, this device has a base plate that extends on the x-y plane and is fixed on clamping element on the chosen positions different on the base plate with at least one, simultaneously, base plate is to have usually extending some connectors between protrusion that is net distribution on the x-y plane and clamping element.

In this known class device, have some mutual intersections on the base plate of device, be the T type groove of net distribution, the upwards taper region of these T type grooves not only is used for determining screw thread by length, and simultaneously also as fitting recess.Be positioned on the following contact-making surface of the clamping element on the bearing-surface on the device base plate and also have and the corresponding T type of above-mentioned T type groove groove.A two-sided T type groove inserted block that accurately assembles combines with bulk-breaking.Each bulk-breaking is combined into one by a common coupling bolt.The stability that connects depends primarily on the intensity of Bolt Connection.Two-sided T type groove inserted block must bear the thrust of x and y direction as assembling and clamping element simultaneously.This class connector is many more in an apparatus structure, and trueness error and loss stability are just big more.This class known devices also has the important shortcoming of another one, promptly need set up hole and groove in order to pass these connectors, is fixed together and these holes and groove only are used for these parts.So just need on the supporting member of workpiece or device, slot, thereby limit its practicality.

From above-mentioned prior art, task of the present invention is to propose a kind of unit type device, and this device can change very much, and fixed clamping piece easily and reliably, and does not need to be provided with screw element on the x-y plane.

Task of the present invention solves thus, and promptly the distance between the datum level of neighboring projection thing equals the distance between the datum level of a protrusion, and perhaps the former is the latter's a even-multiple.Protrusion vertical view particularly of the present invention is a polygon, preferably square is advisable.

By corresponding distance between the regulation protrusion, this distance is the even-multiple of thrust along x, y direction size, and this unit type device can obtain higher adaptability.The interval that forms between the protrusion can be good especially hold various clamping elements.

Between protrusion and clamping element with some additional connectors can be set, for example clamp voussoir or analog.

Below in conjunction with accompanying drawing the present invention is described in detail.

Fig. 1 is a perspective view that has the protrusion that distributes as net shape of rule on base plate;

Fig. 2 is for having the vertical view of ad hoc additional folder clamping element on base plate;

Fig. 3 is the III-III plane along Fig. 2 and obtain cutaway view;

Fig. 4 is the vertical view that has the clamping element of fixed position in one embodiment on base plate.

On base plate 1, be provided with some clocklike be net dress, be square boss thing 6 in the embodiment shown.The side of protrusion has

datum level

6a and 6b, and the datum level 6c along the Z direction that makes progress.The datum level 1a of base plate 1 is parallel with datum level 6c.

In described embodiment, be equal to distance b between the datum level of adjacent different protrusion b apart from a between the datum level 6a respect to one another of same protrusion or between the 6b.

Represent clamping element with 2, this clamping element has a base area, and some protrusions are risen along the Z direction by base area and extend.Two

datum level

12a and 12b that are parallel to each other are all arranged on each protrusion in the thrust 12 of clamping element 2.12c is the contact-making surface of thrust.To device shown in Figure 4, contact-making surface 12c places on the datum level 1a at Fig. 2.In the embodiment shown, datum level 12a respect to one another on the same thrust 12 or the distance b between the 12b are equal to apart from a.

Fig. 4 has represented clamping element 2 fixing on base plate 1, and the back basal plane 2a of clamping element 2 upwards simultaneously.Clamping element 2 by

voussoir

3 and 4 and fill block 5 be fixed on illustrated position.Along the x direction fixedly be to realize by above-mentioned clamping voussoir and fill block, then be to equate to be guaranteed with b apart from a along y direction fixing owing to

protrusion

6 and 12.
