Abstract

The invention relates to a high-precision positioning device for drilling holes. The high-precision positioning device comprises an L-shaped positioning seat and a U-shaped compressing plate, wherein the L-shaped positioning seat is composed of a bottom plate and a lateral plate which are perpendicular to each other and fixedly connected, the lateral plate is provided with a kidney-shaped positioning column, two lateral walls of the lateral plate are provided with dovetail grooves, one end of the U-shaped compressing plate is positioned in the dovetail grooves, and the other end of the U-shaped compressing plate is provided with compressing screws. The high-precision positioning device for drilling the holes is simple in structure, convenient and flexible to use, easy to clamp and high in machining precision.

Description

High-precision drilling hole positioning device
Technical field
The present invention relates to technical field of tooling clamps, relate 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 in the side of its bottom now, but because its bottom is with mounting hole, and on it,, also with two arc sections, 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.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of high-precision drilling hole positioning device is provided, it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High-precision drilling hole positioning device, comprises L shaped positioning seat and U-shaped pressing plate; Described L shaped positioning seat by base plate and side plate mutually vertical being connected form, side plate is with kidney-shaped locating dowel, the two side of side plate is all with dovetail groove, one end of U-shaped pressing plate is positioned at dovetail groove, the other end of U-shaped pressing plate is with housing screw.
The invention has the advantages that: on side plate, arrange with workpiece bottom mounting hole kidney-shaped locating dowel of the same size and from workpiece bottom, it is positioned, the both sides of sidewall are with dovetail groove simultaneously, pressing plate one end is loaded in dovetail groove, other end band screw is for compressing location to two other arc part of workpiece, 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 the structural representation of L shaped positioning seat of the present invention.
Fig. 3 is use state diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the present invention includes L shaped positioning seat and U-shaped pressing plate 3, described L shaped positioning seat by base plate 24 and side plate 22 mutually vertical being connected form, base plate 24 is for being fixed on operating desk by positioning seat, side plate 22 is with kidney-shaped locating dowel 23, be enclosed within locating dowel 23 with the mounting hole of workpiece 1 bottom, workpiece 1 needs the surface, position of boring to make progress, both are measure-alike, workpiece 1 is carried out to vertical direction to be positioned, the two side of side plate 22 is all with dovetail groove 21, one end of U-shaped pressing plate 3 is positioned at dovetail groove 21, pressing plate 3 can slide up and down along dovetail groove 21 at vertical direction, the other end of U-shaped pressing plate 3 is with housing screw 4, housing screw 4 is for carrying out the positioning compression of horizontal direction to workpiece 1, adjust U-shaped pressing plate 3 and can find the best orientation position to workpiece 1 at vertical height, guarantee processing and positioning precision,
Using method of the present invention is as follows:
The first step, is first fixed to L shaped positioning seat on operating desk;
Second step, coordinates the mounting hole of workpiece 1 bottom with the kidney-shaped locating dowel 23 on side plate 22;
The 3rd step, regulates the upper-lower position of pressing plate 3 in dovetail groove 21, and the segmental arc face on 4 pairs of workpiece 1 tops of housing screw is compressed;
The 4th step, carries out Drilling operation to workpiece 1.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
