Abstract

The utility model relates to a positioning device for use in groove milling of an arc-shaped plate. The positioning device comprises a trapezoidal positioning table, wherein the top surface of the trapezoidal positioning table is arc-shaped, and the width of the top surface is the same as that of the arc-shaped bottom surface of a workpiece; the bevel side wall of the positioning table is provided with a positioning hole; a positioning frame is arranged on the vertical side wall of the positioning table; a screw is arranged at the free end of the positioning frame; the end part of the screw is pressed arranged on the upper cambered surface of the workpiece. The positioning device has the advantages of simple structure, flexibility and convenience in use, easiness in clamping and high machining accuracy.

Description

Arc groove milling positioner

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioner that arc is carried out to groove milling processing.

Background technology

Workpiece 1 as described in Figure 1, it is that arc is tabular, now need to be to processing groove 11 on it, because two face is arcwall face, use common positioning tool also can reach accurate location, but the general more complicated of frock, clamping is loaded down with trivial details, and machining accuracy is also difficult to guarantee.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of arc groove milling positioner, and it is simple in structure, flexible and convenient to use, and machining accuracy is high.

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

Arc groove milling positioner, comprise trapezoidal positioning table, the end face of trapezoidal positioning table is arc, the width of end face is identical with the lower arcuate surface width of workpiece, in the ramped side walls of positioning table with locating hole, the upright side walls of positioning table is provided with locating rack, and the free end of locating rack is with screw, and the end of screw is pressed on cambered surface on workpiece.

The utility model has the advantage of: the trapezoidal positioning table with cambered surface is set, the radian of cambered surface is identical with the radian of workpiece lower surface, make two can both fit tightly, the stressed uniform balance of workpiece, at the sidewall of positioning table, locating rack is installed, and by screw by Work-sheet pressing on positioning table, simple in structure, clamping is flexible and convenient to use, and working (machining) efficiency 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 shown in Figure 1 to Figure 2, the utility model comprises trapezoidal positioning table 2, the end face 6 of trapezoidal positioning table 2 is arc, the radian of end face 6 is identical with the radian of the lower arcuate surface of workpiece 1, can make workpiece 1 and positioning table 2 fit tightly, add man-hour, the stressed uniform balance of workpiece 1, guarantee machining accuracy, the width of end face 6 is identical with the lower arcuate surface width of workpiece 1, be convenient to the location of workpiece 1 and positioning table 2, easily determine that whether positioning datum is accurate, in the ramped side walls of positioning table 2 with locating hole 4, can be convenient to trapezoidal positioning table 2 to be fixed on operating desk, the upright side walls of positioning table 2 is provided with locating rack 3, the free end of locating rack 3 is with screw 5, the end of screw 5 is pressed on cambered surface on workpiece 1, make to add man-hour, the position location of workpiece 1 can not be offset,

Using method of the present utility model is as follows:

The first step, is first fixed to trapezoidal positioning table 2 on operating desk;

Second step, by the end face 6 of workpiece 1 positioning table 2, guarantees that the lateral edges of workpiece 1 is concordant with the lateral edges of end face 6;

The 3rd step, installs locating rack 3, is pressed in end face 6 with screw 5 from workpiece 1 top;

The 4th step, carries out groove milling processing to 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.
