Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relate to positioning fixture complex class workpiece being carried out to Drilling operation.
Background technology
Workpiece 1 as shown in Figure 1, Drilling operation is carried out in the side of present needs bottom it, but due to bottom it with mounting hole, and also with two arc sections on it, its complicated structure, uses common positioning tool to carry out Drilling operation to it and there is the phenomenon that precision cannot ensure, 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, provide a kind of high-precision drilling hole positioning device, its structure is simple, and flexible and convenient to use, 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 shape positioning seat and U-shaped pressing plate; Described L shape positioning seat by base plate and side plate mutually vertical being connected form, side plate is with kidney-shaped locating dowel, and the two side of side plate is all with dovetail groove, and one end of U-shaped pressing plate is positioned at dovetail groove, and 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 bottom workpiece, it is positioned, the both sides of sidewall are with dovetail groove simultaneously, pressing plate one end is loaded in dovetail groove, another end band screw is used for carrying out compression location to two other arc part of workpiece, structure is simple, 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 shape positioning seat of the present invention.
Fig. 3 is using state figure of the present invention.
Detailed description of the invention
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 shape positioning seat and U-shaped pressing plate 3, described L shape positioning seat is made up of mutual vertical being connected of base plate 24 and side plate 22, 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 bottom workpiece 1, workpiece 1 needs the portion faces of boring upwards, both are measure-alike, carry out vertical direction to workpiece 1 to position, 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, adjustment U-shaped pressing plate 3 can find the best orientation position to workpiece 1 at vertical height, ensure processing and positioning precision,
Using method of the present invention is as follows:
The first step, is first fixed on operating desk by L shape positioning seat;
Second step, coordinates the mounting hole bottom workpiece 1 with the kidney-shaped locating dowel 23 on side plate 22;
3rd step, regulates the upper-lower position of pressing plate 3 in dovetail groove 21, is compressed in the segmental arc face on housing screw 4 pairs of workpiece 1 tops;
4th step, carries out Drilling operation to workpiece 1.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
