The tool comprises a base; the bottom of the base is provided with a threaded hole and is fixedly connected with an L-shaped support block; the L-shaped support block is provided with a U-shaped support seat; a drilling die with two supports is pivoted with the U-shaped support seat by a positioning pin; each of the two supports is provided with the drilling die and a groove; a pressure plate is compressed on the two supports by matching a bolt with the threaded hole. A right angel notch is arranged at the ridge corner of the base; the side wall, close to the notch, of the base is fixedly connected with a positioning plate provided with a screw rod. The efficient tool for drilling is simple in structure, flexible and convenient to use, simple in clamping and high in machining precision.

Description

Efficient drilling frock

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to for workpiece being carried out to the positioning fixture of Drilling operation.

Background technology

Workpiece 13 as shown in Figure 1, it has the bottom 14 of rectangle, the two ends of bottom 14 are all with a L shaped boss 15, now to process in the bottom of boss 15 through hole 16, use plain clamp to acquire a certain degree of difficulty to its location, especially will guarantee machining accuracy, must use special-purpose frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of efficient drilling frock, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

Efficient drilling frock, comprises base, and the top of base is threaded hole and the L shaped back-up block that is connected, and L shaped back-up block is with U-shaped bearing, with the drill jig of two supports by alignment pin and the pivot joint of U-shaped bearing, on two described supports all with drill jig and groove; Pressing plate coordinates with screwed hole by bolt and is pressed on two described supports; One edges and corners of base, with right-angle notch, near the location-plate that is connected on the sidewall of breach, are provided with screw rod on base on location-plate.

The utility model has the advantage of: according to the concrete structure of workpiece; associated structure is set on base; and the drill jig frame that pivot joint can be overturn on base; on drill jig frame not only with drill jig also have with workpiece on the groove that matches of rectangular base, with this and workpiece, match completely, by pressing plate and location-plate, respectively workpiece is carried out the clamping and positioning of vertical and horizontal direction; simple in structure; flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece.

Fig. 2 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As depicted in figs. 1 and 2, the utility model comprises base 1, the top of base 1 is threaded hole 2 and is connected L shaped back-up block 4, L shaped back-up block 4 is with U-shaped bearing 7, bushing plate 6 with two supports passes through

alignment pin

8 and 7 pivot joints of U-shaped bearing, can carry out installation or removal workpiece 13 by overturn drill template 6, on two described supports all with drill jig 3 and groove 9, behind workpiece 13 location, the position of two drill jigs 3 is just in time corresponding with the position of the through hole 16 of required processing on workpiece 13, groove 9 matches for the rectangular base 14 in workpiece 13, so bushing plate 6 can coordinate with workpiece 13 completely, workpiece 13 is realized to vertical accurately location, pressing plate 5 is coordinated and is pressed on two described supports with screwed hole 2 by bolt, and then workpiece 13 is pressed on base 1, one edges and corners of base 1 are with right-angle notch 10, right-angle notch 10 matches with the L shaped boss 15 on workpiece 13, location-plate 11 is connected on the close sidewall of breach 10 on base 1, screw rod 12 is installed on location-plate 11, boss 15 sidewalls that rotating screw bolt 12 can be from workpiece 13 from horizontal direction by Work-sheet pressing in base,

Using method of the present utility model is as follows:

The first step, is placed in workpiece 13 on base 1;

Second step, coordinates respectively two L shaped boss on workpiece 13 with sidewall and the right-angle notch 10 of base 1, make the groove 9 on the rectangular base 14 of workpiece 13 and two described supports of bushing plate 6 coordinate simultaneously;

The 3rd step, is used described bolt that pressing plate 5 is pressed on workpiece, so vertically by Work-sheet pressing on base 1;

The 4th step, rotating screw bolt 12 will be pressed in the L shaped boss 15 on workpiece 13 from horizontal direction the right-angle notch 10 of base 1;

The 5th step processes through hole 16 on workpiece 13 by drill jig 3.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
