Abstract

The utility model relates to a locating device used during drilling of a precise thin work piece. The locating device comprises a baseplate and a pressure plate, wherein a round locating hole and a T-shaped locating hole are arranged in the top surface of the baseplate, and a connecting hole is arranged between the inner wall of the T-shaped locating hole and the sidewall of the baseplate; a locating column is arranged on the bottom surface of the pressure plate, the locating column is used for cooperative location with the round locating hole in the baseplate, and a drill jig is arranged on the top surface of the pressure plate; during processing, after the work piece is placed in the T-shaped locating hole, the work piece is pressed by an insert while the insert is screwed by a bolt. The drilling locating device, provided by the utility model, has the advantages of simple structure, convenience for operation and high locating and processing precision.

Description

Precise thin Workpiece boring positioner

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to a kind of positioning fixture for the precise thin Workpiece boring is used.

Background technology

Thin workpiece 1 as shown in Figure 1, its bulk that is square, need to carry out Drilling operation on its sidewall 11, but owing to itself only having 2 to 3 millimeters thick, therefore when it is carried out Drilling operation, larger to its positioning difficulty, and very easily distortion, if guarantee its borehole accuracy and guarantee indeformablely, must make Special positioning tool.

The utility model content

The utility model provides a kind of precise thin Workpiece boring positioner for the problems referred to above of the prior art, and it is simple in structure, and is easy to operate, and the location machining accuracy is high.

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

Precise thin Workpiece boring positioner comprises base plate, pressing plate, with circular locating hole and T shape locating hole, between the inwall of T shape locating hole and the sidewall of base plate, connecting hole is arranged on the end face of base plate; The pressing plate bottom surface is with locating dowel, locating dowel be used for base plate on circular locating hole coordinate the location, the end face of pressing plate is with drill jig; Add man-hour, workpiece is pushed down with inserting after putting into T shape locating hole, and bolt screws and inserts simultaneously;

Further technical scheme is as follows:

On the quantity of circular locating hole of distributing on described base plate and pressing plate, the quantity of Distribution and localization post is 3;

The degree of depth of described T shape locating hole is identical with the length of workpiece.

The utility model has the advantage of: locating hole is set on base plate is used for positioning workpieces, by be arranged in locating hole insert and sidewall of the bottom plate on bolt with Work-sheet pressing, place simultaneously pressing plate above base plate, on pressing plate with drill jig and gas hole, after machining, by gas hole, workpiece is blown out; Simple in structure, easy to operate, the location machining accuracy is high.

The specific embodiment

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

As extremely shown in Figure 5 in Fig. 1, the utility model comprises base plate 2, pressing plate 3, it is characterized in that: uniform 3 circular locating holes 22 and T shape locating hole 23 on the end face 21 of base plate 2, between the inwall of T shape locating hole 23 and the sidewall of base plate 2, connecting hole 24 is arranged, the degree of depth of T shape locating hole 23 is identical with the length of workpiece 1, after workpiece 1 is put into T shape locating hole 23, need the plane 11 of holing concordant with the end face 21 of base plate 2 on workpiece 1; Uniform 3 locating dowels 31 in pressing plate 3 bottom surfaces, locating dowel 31 be used for base plate 2 on circular locating hole 22 coordinate the location, the end face of pressing plate 3 is with drill jig 33; Add man-hour, after workpiece 1 is put into T

shape locating hole

23,5 push down with inserting, bolt 4 screws and inserts 5, workpiece pressing 1 simultaneously;

Use method of operating of the present utility model is as follows:

The first step, is put into T shape locating hole 23 to workpiece 1 with the end face 11 that needs on workpiece 1 to hole up, will insert simultaneously 5 to put in locating hole 23, and will insert with bolt 4 from the sidewall of

base plate

2 and 5 screw, and workpiece 1 is clamped;

Second step matches the locating dowel 31 on pressing plate 3 with circular locating hole 22 on base plate 2, pressing plate 3 is pressed on base plate 2;

In the 3rd step, the end face 11 of the 33 pairs of workpiece 1 of drill jig from the pressing plate 3 carries out Drilling operation, after machining, bolt 4 is unscrewed, and takes off pressing plate 3 and workpiece 1 can be taken out.

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