Description

Back inversed clamp

Technical field

The utility model relates to a kind of anchor clamps, especially a kind of back inversed clamp.

Background technology

The positioning supports direction of common clamp for machining and processing cutting force direction are in opposite directions, the anchor clamps locating surface is bearing cutting force, if but technological requirement must be processed on the workpiece locating surface, then to adopt the locate mode of losing money instead of making money pattern, at present, also do not have back inversed clamp, the machining industry but is badly in need of back inversed clamp.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of clamp operation convenient, directed precisely, can better protect the back inversed clamp that workpiece is injury-free, can process on the workpiece locating surface.

The technical scheme that provides according to the utility model, described back inversed clamp, be included in hard-wired panel on the pedestal, on panel, offer handle hole, be fixed with location benchmark core in the bottom surface of panel, panel bottom surface in location benchmark core one side is fixed with the duplex detent mechanism, also is provided with rocking arm supporting plate mechanism in the bottom surface of panel.

Described duplex detent mechanism is included in two auxiliary guide pillars of the interior sliding plug of slide opening of slip locating piece, two auxiliary guide pillars be arranged in parallel, between the end, the same side of two auxiliary guide pillars, be connected with the connection handle, be embedded with the rolling positioning body in two auxiliary guide pillar ends with connection handle opposite side, two auxiliary guide pillars between rolling positioning body and slip locating piece are put on the shelf and are provided with sliding connection block.With respect to the auxiliary guide pillar end that connects the handle opposite side along axially being bolted with holding screw, the holding screw end that is in the auxiliary guide pillar outside offers the spherical recess greater than half sphere, be embedded with spherical rolling positioning body in this spherical recess, be exposed to outside the spherical recess less than the rolling positioning body of half sphere.The guide pin bushing that is used for the auxiliary guide pillar of sliding plug respectively is installed in the slip locating piece at slide opening two ends.

Described rocking arm supporting plate mechanism is included in the hard-wired holder of panel upper surface, and the fixedly connected installing plate that stretches out downwards on the holder by the hinged rocking arm of clamping plate, is provided with supporting plate at the rocking arm inner end on the installing plate, and the rocking arm outer end is an operating grip.

The utlity model has clamp operation convenient, directed precisely, can better protect workpiece injury-free, advantage such as can on the workpiece locating surface, process.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: this back inversed clamp, be included in hard-wired panel 2 on the pedestal 1, on panel 2, offer handle hole 3, be fixed with location benchmark core 4 in the bottom surface of panel 2, bottom surface at the panel 2 of locating benchmark core 4 one sides is fixed with duplex detent mechanism 5, also is provided with rocking arm supporting plate mechanism 6 in the bottom surface of panel 2.

Described duplex detent mechanism 5 is included in two auxiliary guide pillars 53 of the interior sliding plug of slide opening of slip locating piece 51, two auxiliary guide pillars 53 be arranged in parallel, between the end, the same side of two auxiliary guide pillars 53, be connected with and connect handle 57, be embedded with rolling positioning body 56 in two auxiliary guide pillar 53 ends with connection handle 57 opposite sides, two auxiliary guide pillars 53 between rolling positioning body 56 and slip locating piece 51 are put on the shelf and are provided with sliding connection block 54.With respect to auxiliary guide pillar 53 ends that connect handle 57 opposite sides along axially being bolted with holding screw 55, holding screw 55 ends that are in auxiliary guide pillar 53 outsides offer the spherical recess greater than half sphere, be embedded with spherical rolling positioning body 56 in this spherical recess, be exposed to outside the spherical recess less than the rolling positioning body 56 of half sphere.The guide pin bushing 52 that is used for the auxiliary guide pillar 53 of sliding plug respectively is installed in the slip locating piece 51 at slide opening two ends.

Described rocking arm supporting plate mechanism 6 is included in the hard-wired holder 61 of upper surface of panel 2, the fixedly connected installing plate that stretches out downwards 62 on the holder 61, by clamping plate 63 hinged rocking arms 64, be provided with supporting plate 65 at rocking arm 64 inner ends on the installing plate 62, rocking arm 64 outer ends are operating grip.

The utility model operation principle is as follows:

This back inversed clamp uses location benchmark core 4, again by duplex detent mechanism 5 orientations, when duplex detent mechanism 5 uses, when the user promotes to connect handle 57, auxiliary guide pillar 53 just steadily advances under the effect of guide pin bushing 52, under the guide effect of sliding connection block 54, make rolling positioning body 56 contact locating surfaces simultaneously, all having sticked locating surface when 56 whiles of rolling positioning body of the right and left is that clamping is finished.This device positioning accuracy height, mechanism is simple, and feel is obvious.The user also can finish by dead by more direct sensation anchor point, and locating surface is adjacent to fully.With rocking arm supporting plate mechanism 6 workpiece is upwards held up, avoided using the trouble of the fixing workpiece of traditional screw rod.Avoided being subjected to the part shape limitation in the clamping process, guaranteed the unification of clamping benchmark and product requirement location benchmark.
