Description

A kind of work-table board clamp

Technical field:

The utility model relates to a kind of workbench, particularly is a kind of work-table board clamp with multiple shape clamping face.

Background technology:

The platen anchor clamps of existing workbench are to be provided with two pins in its bottom, need during use the anchor clamps pin is inserted in the jack that is had on the platen, to finish object is clamped, this just need have a plurality of jacks on platen, and these jacks make the intensity of platen reduce the plane that table top is kept perfectly, and owing to the setting of position between jack is fixed, when clamping difference object, need the different jack position of conversion, thereby limited the changeability of chucking position, bring inconvenience for processing work, make the scope of application of platen dwindle.

Summary of the invention:

But goal of the invention of the present utility model provides a kind of work-table board clamp with multiple shape clamping face and flexible positioning.

Realize that technical solution of the present utility model is as follows: comprise plate-like chuck body, key is to be provided with a strip projection along the body longitudinal direction in the body bottom.

The clamping face that the utlity model has multiple shape also can convenient moving with accurate be located on the chute of platen, the object of clamping different length, thickness and shape neatly, and make table top keep smooth, thus reached the purpose of convenience processing, enlarged the scope of application of workbench.

The specific embodiment:

See also Fig. 1 to Figure 12, specific embodiment of the utility model is as follows: body 1 is a polygon plate, is provided with a strip projection 2 along body 1 longitudinal direction in its bottom, and this projection 2 can embed in the groove of offering on the platen 13 14 and can slide along this groove; The cross sectional shape of the cross sectional shape of strip projection 2 and platen groove is suitable, when the platen groove is dovetail groove, then the cross section of projection 2 is swallow-tail form, projection 2 can be isometric with the longitudinal length of body 1, if the platen groove is a terrace with edge shape groove, and the upper bottom surface of this groove is provided with an opening, then the cross section of strip projection 2 is inversion "T"-shaped (being  shape), and with projection 2 at nearly intermediate open position one breach, projection 2 is removed sub-fraction, make it be divided into two projections, and keep a determining deviation between this two projection, so that in this spacing, place a nut 10.

But for making the object of anchor clamps clamping different shape, body 1 is a polygon shape, its plan view shape can be the hexagon body of tool straight flange and hypotenuse, the forward limit of body 1 or other limits all can be provided with an excrescence 3 that extends outward suitable length from this limit, the length of extended excrescence 3 and width can be a cuboid or square as required, the width of excrescence 3 is less than the width on this limit, 3 liang of outsides of excrescence respectively form an angle α with this intersection, limit respectively, angle α can be the right angle, also can be the obtuse angle, or one angle α be the right angle, another angle α is the obtuse angle; The top end face of excrescence 3 can have a groove 4 along the level or the vertical direction of this excrescence, and groove 4 can be " V " shape or " U " shape groove, and the angle of " V " groove can be 90 °; During use, available a plurality of anchor clamps carry out combination collocation to be used, just but the difform workpiece of clamping, but the just tetragonal workpiece in clamping right angle of the body 1 that four tool excrescences 3 is arranged as utilization, guarantee the precision of right-angle side, or with the right-angle side framework of body 1 clamping " L " shape of three tool excrescences 3.

But be the object of clamping arc, one side face of body 1 can be provided with a circular arc protuberance 5 or arc depression 6, also can be provided with circular arc protuberance 5 at one side of body 1 face, and the another side face is provided with arc depression 6.

But be the thin object of clamping, all can be provided with one or multi-channel groove 7 at one side of body 1 face or other limit face, groove 7 can be elongated right-angle side groove, this groove can be along the horizontal or vertical direction setting of body 1 limit face, or be arranged on the base of body 1 limit face, make the base form a kerf 15, so that will be pressed on the platen than thin object.

For making anchor clamps the annex that other have special clamping face can be installed conveniently, can on one side of body 1 face or a plurality of limits face, be provided with a plurality of rectangle shrinkage pools 8, the pass of shrinkage pool 8 is identical or different and be that rule distributes, shrinkage pool 8 can be used for the pegging graft associate member of tool pin suitable with it is so that the special-shaped workpiece of clamping; Or also can offer a plurality of vertical square tube hole 16 that is in line at body 1, so that plant other accessory.

Can on platen, locate for making anchor clamps, body 1 is provided with a locking mechanism of being made up of screw rod 9, nut 10 and back-up ring 11, wherein an end of screw rod 9 is provided with a knob 12, the cross section of knob 12 is "T"-shaped, the periphery of knob 12 heads has several fins, so that moving with hand-screw, there is the cylinder of downward extension this knob head bottom surface, and the basal surface of cylinder can contact with the upper surface of body 1; The spin nut end of screw rod 11 from body 1 offer perpendicular to the bottom of stretching out body 1 thoroughly the through hole that is the breach position of center line of being inverted "T"-shaped (being  shape) projection 2 by the cross section that is separated, the length of the screw rod that this stretches out thoroughly is less than the height of projection 2, back-up ring 11 is an annular collar, its excircle diameter is slightly less than the cross section, and to be the cross section of connector of  shape projection 2 heads and body 1 long, back-up ring 11 is nested with on this screw rod that stretches out thoroughly, and it can make screw rod 9 not deviate from from body 1; Nut 10 is for square and be spirally connected with screw rod 9, and this nut places the breach of projection 2, and the projection 2 on breach both sides can make nut 10 not with screw rod 9 turns, and the thickness of this nut is less than the cross section height of the  shape head of projection 2; During use, make screw rod 9 screw nut 12 by turn knob 12 and get final product.
