Further, described base plate is provided with guide groove, and described V-block bottom is fixed with positioning key, and described V-block passes through Its positioning key is realized sliding on base plate with described guide groove cooperation.

Yet further, described V-block bottom is provided with recess, is provided with screw in recess, and it is solid that described positioning key passes through bolt It is scheduled in described recess.

Further, described V-block bottom is provided with groove, and described V-block is passed through its groove and realized with described base plate cooperation Base plate slides.

Further, described clamp system includes briquetting, screw rod, nut and spring, and described spring is socketed with screw rod and sets Below briquetting, described nut is coordinated above briquetting with screw rod, and described clamp system is bolted on the one of V-block End.

Further, described V-block is provided with V-groove number is at least one.

Yet further, described base plate is provided with the hole for hoist for lifting.

The beneficial effects of the utility model：V-block can on fixture horizontal slidable adjustment being bolted, so as to Make fixture be applied to the workpiece of different length size, suitable dimensions scope is wide, eliminate from simultaneously or change V-block locating clip Tool step and by setting a plurality of V-groove workpiece is processed simultaneously, operating efficiency can be effectively improved.

Brief description

Fig. 1 is the overall structure diagram of embodiment one of the present utility model；

Fig. 2 is the overlooking the structure diagram of embodiment one of the present utility model；

Fig. 3 is the overall structure diagram of embodiment two of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in detail.

Embodiment one

As depicted in figs. 1 and 2, a kind of adjustable V type block positioning fixture, including base plate 1, the clamping machine for clamping workpiece Structure 2 and the V-block 3 being separately positioned on two ends on base plate 1.Described clamp system 2 includes briquetting 2.1, screw rod 2.2, nut 2.3 and Spring 2.4, described spring 2.4 is socketed and below briquetting 2.1 with screw rod 2.2, and described nut 2.3 is set with screw rod 2.2 cooperation Above briquetting 2.1, described clamp system 2 is bolted on one end of V-block 3.Described base plate 1 both sides are provided with some use In the installing hole 1.1 of fixing described V-block 3, described installing hole 1.1 is equally spaced, and described base plate 1 is provided with guide groove 1.2, institute State V-block 3 bottom and be provided with recess 3.3, be provided with screw 3.4 in recess 3.3, be bolted in recess 3.3 and be provided with positioning key 3.2, described V-block 3 can be realized sliding on base plate 1 with described guide groove 1.2 cooperation by its positioning key 3.2.Described V-block 3 It is provided with least one V-groove 3.1, in figure only illustrates the embodiment of two V-groove 3.1, it is not limited to two V-groove 3.1, in order to improve operating efficiency, realize multi-work piece and process simultaneously, a plurality of V-groove 3.1 can be arranged as required to, such as three or Article four, all in protection domain of the present utility model.Described bottom 1 plate is provided with the hole for hoist 1.3 for lifting.

Embodiment two

As shown in figure 3, embodiment two is roughly the same with the technical scheme of embodiment one, it differs only in V-block 3 and bottom The sliding matching mode of plate 1 is different.In embodiment two, V-block 3 bottom is provided with groove 3.5, and base plate 1 is placed in the groove of V-block 3 In 3.5, described V-block 3 passes through its groove 3.5 and realizes sliding on base plate 1 with described base plate 1 cooperation.

Implementation process is as follows：

Length dimension first according to workpiece, adjusts the distance between two pieces of V-blocks 3 along the guide groove 1.2 on base plate 1, then Workpiece is put into 3.1 on V-groove, turns the nut 2.3 of clamp system 2 with spanner, so that pressing plate 2.1 is moved down and workpiece pressing Processing is entered to workpiece.V-block 3 of the present utility model can on base plate 1 horizontal slidable adjustment being bolted, so as to make Fixture is applied to the workpiece of different length size, and suitable dimensions scope is wide, eliminates from simultaneously or changes V-block positioning fixture Step and by arrange a plurality of V-groove 3.1 workpiece is processed simultaneously, operating efficiency can be effectively improved.
