Description

Machined positioning fixture

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture for workpiece is processed.

Background technology

For the more complicated workpiece of structure, it is being positioned and is adding man-hour, use plain clamp to acquire a certain degree of difficulty to its location, especially to guarantee machining accuracy, must use special-purpose frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of machined positioning fixture, 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:

Machined positioning fixture, comprises trapezoidal base, the first locating piece and the second locating piece, and sidewall of trapezoidal base and top are respectively with dovetail groove and locating hole; The first locating piece and equal vertical screw rod that is connected on the second locating piece, the end of the screw rod compact heap that is all connected; The first locating piece sidewall bucking ladder that is connected, bucking ladder is positioned at dovetail groove, the second locating piece by screw fastening in the sidewall of trapezoidal base; On trapezoidal base, between two relative inclined-planes, be through hole, the bottom of described through hole is with U-shaped holddown groove.

The utility model has the advantage of: according to the positioning requirements to workpiece, in base top, locating hole is set workpiece is carried out to vertical positioning supports, in the two side of base, locating piece is installed simultaneously, by the screw rod on locating piece, workpiece is carried out to being fixedly clamped of horizontal direction, make wherein simultaneously one or whole locating piece can height up and down, according to the practical structures of workpiece, different workpiece is positioned, play the effect of a frock multi-work piece, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is structural representation 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, the utility model comprises trapezoidal base 1, the first locating piece 4 and the second locating piece 7, sidewall of trapezoidal base 1 and top are respectively with dovetail groove 3 and locating hole 2, when workpiece is placed in base 1 top, locating hole 2 coordinates with the alignment pin on workpiece, vertically workpiece is being positioned; The first locating piece 4 and equal vertical screw rod 5 that is connected on the second locating piece 7, the end of screw rod 5 compact heap 9 that is all connected, rotary screw 5 can make 9 pairs of workpiece of compact heap clamp; The first locating piece 4 sidewalls bucking ladder 6 that is connected, bucking ladder 6 is positioned at dovetail groove 3, can make the first locating piece 4 vertically along dovetail groove 3, move, and the second locating piece 7 is anchored on the sidewall of trapezoidal base 1 by screw 8; On trapezoidal base 1, between two relative inclined-planes, be through hole, can alleviate the weight of base 1, facilitate movement and the dismounting of base 1, the bottom of described through hole, with U-shaped holddown groove 10, can be fixed on base 1 on operating desk by U-shaped holddown groove 10;

Using method of the present utility model is as follows:

The first step, is fixed on base 1 on operating desk;

Second step, is placed in the top of base 1 workpiece and the alignment pin on workpiece is coordinated with the locating hole 2 on base 1;
