Abstract

The utility model relates to a high-precision punching positioning device, comprising an L-shaped positioning seat, wherein the L-shaped positioning seat is formed by mutually vertically and fixedly connecting a bottom plate and a side plate; the side plate is provided with a positioning pillar; two L-shaped press plates are symmetrically mounted in a way of taking the positioning pillar as a center; compression screws are arranged on the press plates; a support plate is arranged on the bottom plate; a locating pin is inserted in a locating hole of the support plate and is fixed by a screw; the locating pin is vertical to the side plate. The high-precision punching positioning device is simple in structure, flexible and convenient to use, simple in clamping and high in processing precision.

Description

High accuracy punching positioner

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture that complex class workpiece is carried out to Drilling operation.

Background technology

Workpiece 1 as shown in Figure 1, need to carry out Drilling operation at its arc part 14 now, but because it has the boss 12 of disc-shaped base 11 and uniform arc cylinder, on boss 12, also with center counterbore 13, its complicated structure, is used common positioning tool to carry out to it phenomenon that Drilling operation exists precision to guarantee, if use the frock that can reach required precision, but often very complicated, clamping is loaded down with trivial details, affects working (machining) efficiency.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high accuracy punching positioner, 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:

High accuracy punching positioner, comprises L shaped positioning seat, described L shaped positioning seat by base plate and side plate mutually vertical being connected form, side plate is with locating dowel and symmetrical centered by described locating dowel two L shaped pressing plates are installed, on pressing plate all with housing screw; On base plate, with gripper shoe, be inserted with alignment pin and fix by screw in the locating hole of gripper shoe, alignment pin is perpendicular to side plate.

The utility model has the advantage of: locating dowel is set on sidewall and from workpiece bottom, it is positioned, pressing plate is installed simultaneously, its bottom is compressed, gripper shoe and alignment pin are installed simultaneously on base plate, by alignment pin, the other end on workpiece is compressed to location, 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 use state diagram 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 L shaped positioning seat, described L shaped positioning seat by base plate 2 and side plate 7 mutually vertical being connected form, side plate 7 is with locating dowel and symmetrical centered by described locating dowel two L shaped pressing plates 5 are installed, described locating dowel is for positioning the circular hole on workpiece 1 chassis 11, on pressing plate 5, all with housing screw 6, housing screw 6 withstands on the surface on workpiece 1 chassis 11; On base plate 2 with gripper shoe 3, in the locating hole of gripper shoe 3, be inserted with alignment pin 4 and fix by screw, alignment pin 4 is perpendicular to side plate 7, and alignment pin 4 is positioned in workpiece 1 center counterbore 13 from the front of workpiece 1, described screw is fixed alignment pin 4, prevents that alignment pin 4 is loosening;

Using method of the present utility model is as follows:

The first step, is first fixed to L shaped positioning seat on operating desk;

Second step, coordinates the circular hole on workpiece 1 chassis 11 with the locating dowel on side plate 7;

The 3rd step, regulates the housing screw 6 on pressing plate 5 to compress the chassis 11 of workpiece 1;

The 4th step, first alignment pin 4 inserts in the center counterbore 13 in workpiece 1 front and is screwed;

The 5th step, carries out Drilling operation to the arc part 14 on workpiece 1.

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.
