Abstract
The utility model discloses a holddown clamp which comprises a base and a holddown plate. The base plate is provided with a positioning hole and a supporting post. The holddown plate is provided with a long groove, and a wear plate is mounted in the long groove. The positioning hole is a counter bore, the supporting post is mounted in the counter bore, and a workpiece is clamped between the wear plate and the supporting post. The wear plate is arranged to avoid direct contact between the holddown plate and the workpiece, has good wear resistance, and can be changed directly once being damaged, so that service life of the clamp is prolonged and service cost thereof is saved; as the supporting post is mounted in the positioning counter bore, the upper end of the supporting post is limited in a horizontal direction, and the structural stability of the whole clamp is improved.
Description
Technical field
The utility model relates to machining servicing unit, relates in particular to a kind of clamp jig.
Background technology
Along with the development of Machining Technology, the kind of machined part is also more and more, corresponding needed fixture kind is also more and more, clamp jig is one comparatively conventional in bore process, traditional clamp jig directly by pressing plate by workpiece pressure holding to the support column of pedestal, but this structural stability is poor, and be easy to wearing and tearing, service life is short.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of reliable and stable and clamp jig that anti-wear performance is good.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of clamp jig, comprise pedestal and pressing plate, described pedestal is provided with locating hole and support column, described pressing plate is provided with strip groove, in described strip groove, wearing plate is installed, described locating hole is counterbore, and described support column is installed in described counterbore, and workpiece is held between described wearing plate and described support column.
Be provided with wearing plate, avoided pressing plate directly to contact with workpiece, support column is installed in the counterbore of location, make the upper end of support column have in the horizontal direction restriction.
As preferably, described wearing plate is strip, and is installed in described strip groove by bolt.
As preferably, the nut of described bolt embeds in described wearing plate.
As preferably, the supporting surface of the pressure holding face of described wearing plate and described support column is provided with anti-skidding striped.
The beneficial effects of the utility model are:
The utility model is provided with wearing plate, avoid pressing plate directly to contact with workpiece, there is good anti-wear performance, if damaged, can directly change wearing plate, extend service life, save use cost, support column is installed in the counterbore of location, makes the upper end of support column have in the horizontal direction restriction, improved the Stability Analysis of Structures performance of whole fixture.
Brief description of the drawings
Fig. 1 is the structural representation of clamp jig described in the utility model;
Fig. 2 is the structural scheme of mechanism of pressing plate described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises pedestal 1 and pressing plate 4, pedestal 1 is provided with locating hole 7 and support column 2, pressing plate 4 is provided with strip groove 9, wearing plate 6 is installed in strip groove 9, wearing plate 6 is strip, and be installed in strip groove 9 by bolt 5, the nut of bolt 5 embeds in wearing plate 6, can not affect like this clamping effect, locating hole 7 is counterbore, support column 2 is installed in counterbore, workpiece 3 is held between wearing plate 6 and support column 2, in order to prevent that workpiece 3 from sliding in the horizontal direction, the supporting surface of the pressure holding face of wearing plate 6 and support column 2 is provided with anti-skidding striped 8.
The wearing plate 6 that is provided with described in the utility model, avoid pressing plate 4 directly to contact with workpiece 3, there is good anti-wear performance, if damaged, can directly change wearing plate 6, extend service life, save use cost, support column 2 is installed in the locating hole 7 of counterbore shape, makes the upper end of support column 2 have in the horizontal direction restriction, improved the Stability Analysis of Structures performance of whole fixture.
