The automatic-flexing horizontal adjustment device comprises an L-shaped right-angle jig, and the longer segment of the jig is sheathed with an adjustment block in a sliding and matching way; and the jig is connected with the adjustment block to form a guide rail slot. The adjustment device has the advantages of simple structure, convenient use, low production cost, as well as stable and precise workpiece clamping and locating.

Description

The flexible automatically horizontal adjusting device of flat-nose pliers

Technical field

The utility model discloses the flexible automatically horizontal adjusting device of a kind of flat-nose pliers, belong to clamping orientation tool technical field.

Background technology

In machining, the occasion that applies to the flat-nose pliers clamping is more ordinary, is because flat-nose pliers is the auxiliary equipment in the machining equipment.As the hole processing on the processing of the hole on the bench drill, the radial drilling machine, the smear metal processing on the planer, the smear metal processing on the machining center etc.It is to rely on two guide pass and two clamping claws to be used as reference for installation that flat-nose pliers is finished in clamping process, if workpiece therewith reference for assembling fully contact and clamp, just can meet substantially with machining benchmark.And, by the clamping of these four reference for installation, just can the firm grip workpiece, just controlled the six-freedom degree of workpiece fully, workpiece is not just had again and is moved or the generation of rotation phenomenon.For this reason, to fixedly positioning in the flat-nose pliers use be considerable for the maintenance of flat-nose pliers guide pass and workpiece.But because in process, the workpiece of clamping in flat-nose pliers is blank or semi-finished product substantially, if directly coarse workpiece clamping on guide pass, flatness, roughness of guide pass etc. will directly be had influence on, some in addition destroyed the precision of the guide pass of whole flat-nose pliers, this will directly have influence on the machining accuracy grade in process; The workpiece that has is owing to reasons such as thickness or insufficient heights, directly fix workpiece with former and later two clamping claws in the flat-nose pliers, make the guide pass of workpiece and flat-nose pliers unsettled, can produce many unfavorable factors like this, will directly influence machining accuracy and positioning accuracy; Have plenty of these factors of having considered, under the situation of thickness of workpiece or insufficient height, the bed hedgehopping piece of using some respective length is placed on the guide pass, to solve above unfavorable factor.But under the small lot processing environment, this will influence process time, be because increased time.

The utility model content

The deficiency that the utility model exists at prior art, purpose is to provide a kind of low production cost simple in structure, easy to use, makes the piece-holder positioning stablity flexible automatically horizontal adjusting device of flat-nose pliers accurately.

The technical scheme of the utility model technical solution problem is as follows: the flexible automatically horizontal adjusting device of a kind of flat-nose pliers is characterized in that: comprise " L " type right angle anchor clamps, its long section formula of being slidingly matched is with the adjustment piece, and anchor clamps link to each other with the adjustment piece and form guide-track groove.

The utility model further is set to:

Be provided with in the middle of the described adjustment piece and the corresponding groove of anchor clamps long section shape size, and groove is a through slot.

The cross sectional shape of the long section of described groove and anchor clamps is the corresponding rectangles of 45 in both sides, top.

Each angle of described guide-track groove is the right angle.

The utility model has solved defectives such as the guide pass destructible, clamping shakiness, the location that have flat-nose pliers in the prior art are inaccurate, time is long.In use, the flexible automatically horizontal adjusting device of flat-nose pliers freely is placed on two guide pass of flat-nose pliers, workpiece is placed on this automatically flexible horizontal adjusting device, clamping work pieces, this will change the phenomenon because of the not enough location shakiness that causes of restriction of the free degree; Can do to stretch mutually between " L " type right angle anchor clamps of horizontal adjusting device and the adjustment piece because this flat-nose pliers stretches automatically, this will change the different defectives that will set up corresponding bed hedgehopping piece of length because of workpiece, save the leading time; And owing between flat-nose pliers and workpiece, be provided with this adjuster, improved the factor that workpiece directly contacts the flat-nose pliers guide pass, protected the precision of guide pass.
