Abstract

The utility model relates to a drilling jig, which comprises a soleplate, a nut, bolts, a panel and a fixed plate, wherein one end of the soleplate is fixedly connected with the panel, and the other end of the soleplate is fixedly connected with the fixed plate; the center of the soleplate is provided with a through groove, and the size of the through groove is allowable for a work-piece to rotate by 360 degrees; two sides of the soleplate are respectively provided with a threaded hole; each threaded hole is provided with a bolt, and the bolts penetrates the two sides to reach the through groove; a semicircular groove is arranged on the same central line of the panel, a base and the fixed plate; the work-piece is arranged on the semicircular groove, one end of the work-piece pushes against the fixed plate, and the other end of the work-piece penetrates the panel; the panel is also provided with a nut; the work-piece is fixed on the jig through the nut and the bolts, and the through groove is square; and the quantity of the bolts is two. The drilling jig not only can well guarantee the coaxiality between the holes on the upper end surface and the lower end surface when machining the work-piece, but also is simple to operate and capable of improving the production efficiency of the products.

Description

A kind of boring grab

Technical field

The utility model relates to a kind of anchor clamps, especially a kind of anchor clamps that are used to process the I shape hole.

Background technology

Prior art needs three holes of processing altogether in processing I shape hole as shown in Figure 3, comprise hole B and two hole A that diameter is identical; General processing method all is to be fixed to workpiece on the drilling machine earlier, processes the hole B of workpiece centre then earlier, then is the hole A of benchmark processing upper surface with hole B; Disassemble workpiece, continuing conversely with hole B is the hole A of benchmark processing other end, though can process workpiece; But the axiality of the hole A of upper surface that processes like this and lower surface can not guarantee, and will carry out twice loading and unloading, troublesome poeration; Reduce production efficiency, improved production cost.

The utility model content

The utility model purpose is for the deficiency that overcomes prior art a kind of boring grab to be provided, and has solved in processing I shape hole the problem that the axiality in the hole of upper surface and lower surface can not guarantee.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of boring grab comprises base plate, nut, bolt, panel and fixed head; Said base plate one end is fixedly connected with panel, and the other end is fixedly connected with fixed head; The center of said base plate has a groove, and the big I of groove lets workpiece do 360 ° rotation; The both sides of said base plate have screwed hole; Said screwed hole is provided with bolt, and bolt passes both sides in groove; Have half slot on the same center line of said panel, base and fixed head; Said workpiece is positioned on the half slot, and workpiece one end withstands on the fixed head, and the other end passes panel; Also be provided with nut on the said panel; Said workpiece is fixed on the anchor clamps through nuts and bolt.

Preferably, said groove is a square.

Preferably, said bolt is two.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

A kind of boring grab of the utility model scheme in processing I shape hole, at first processes the hole of centre bore and upper surface; Unclamp bolt then; Workpiece Rotate 180 °, fix the hole that bolt well continues the processing lower surface again, can not only well guarantee the axiality between the hole of upper surface and lower surface like this; And simple to operate, improved production efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model technical scheme is described further:

View when accompanying drawing 1 is the use of boring grab of the utility model;

Accompanying drawing 2 is the structural representation of the boring grab of the utility model;

Accompanying drawing 3 is the sectional view of workpiece of the boring grab of the utility model;

Wherein: 1, base plate; 2, workpiece; 3, panel; 4, nut; 5, fixed head; 6, groove; 7, bolt; 8, half slot.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.

Accompanying drawing

1,2,3 is the described a kind of boring grab of the utility model, comprises base plate 1, nut 4, bolt 7, panel 3 and fixed head 5; Said base plate 1 one ends are fixedly connected with panel 3, and the other end is fixedly connected with fixed head 5; The center of plate of the said end 1 has a groove 6, and the big I of groove 6 lets workpiece 2 do 360 ° rotation; The both sides of said base plate 1 have screwed hole; Said screwed hole is provided with bolt 7, and bolt 7 passes both sides in the groove 6; Have half slot 8 on the same center line of said panel 3, base plate 1 and fixed head 5; Said workpiece 2 is positioned on the half slot 8, and workpiece 2 one ends withstand on the fixed head 5, and the other end passes panel 3; Also be provided with nut 4 on the said panel 3; Said workpiece 2 is fixed on the anchor clamps through nut 4 and bolt 7; Said groove 6 is a square; Said bolt 7 is two.

Such during concrete operation, at first be put into workpiece on the half slot 8, be fixed to workpiece 2 on the anchor clamps through the bolt 7 of base plate 1 both sides and nut 4 on the fixed head 5 then; To drilling machine, the hole B of processing work 2 then is that B is the hole A of benchmark processing upper surface with the hole then clamps; Unclamp the bolt 7 of base plate 1 both sides, behind workpiece 2 Rotate 180s °, fix workpiece 2 with bolt 7 after; Continuation is the hole A of benchmark processing lower surface with hole B, and the position of workpiece does not change in the hole A of processing upper surface and lower surface like this, can well guarantee two axialities between the A of hole; It is simple in structure; Simple to operate, improved production efficiency, guaranteed the quality of product.

Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
