Abstract

The utility model relates to an efficient outer circle turning clamp, comprising a positioning disc; the positioning disc is provided with a clamping section; the end surface of the clamping section is provided with positioning pins; pressure plates are positioned by the positioning pins and are fixedly connected onto the end surface of the clamping section through screws; the positioning disc is provided with a rectangular through hole along the axial direction; a U-shaped slot is arranged at the bottom of the rectangular through hole; a through slot is formed from the outer circle of the positioning disc to the through hole. The efficient outer circle turning clamp is simple in structure, flexile and convenient to use, simple in clamping and high in machining precision.

Description

Efficient turning clamp

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture for workpiece being carried out to turning.

Background technology

Workpiece 1 as shown in Figure 1, it has a rectangular end and cylinder 11, because this workpiece 1 is to obtain by casting, the size of cylinder 11 and surface quality all do not meet technical requirement, conventionally use the mode of Vehicle Processing, and the cylindrical of cylinder 11 is carried out to turning processing, the existence of rectangular end, make it have certain difficulty, and location clamping also must guarantee that clamping is easy, does not affect working (machining) efficiency.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of efficient turning clamp, 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:

Efficient turning clamp, comprises positioning disk, and on positioning disk, with gripping section, the end face of gripping section is with alignment pin, and pressing plate is located by alignment pin and by screw, is fixed on the end face of gripping section; Positioning disk has rectangular through-hole along axis direction, and the bottom of rectangular through-hole is with U-lag, and the cylindrical of positioning disk to through hole has groove.

The utility model has the advantage of: according to the structure of workpiece, the through hole identical with workpiece rectangular end is set on positioning disk, briquetting is installed simultaneously on the end face of gripping section and is compressed from the rectangular end bottom of workpiece, positioning disk cylindrical has groove to through hole, makes positioning disk have elasticity, is beneficial to workpiece rectangular end is clamped, 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 structural representation of the present utility model.

Fig. 3 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 3, the utility model comprises positioning disk 2, on positioning disk 2 with gripping section 4, be convenient to be clamped on the scroll chuck of lathe, the end face of gripping section 4 is with alignment pin 6, pressing plate 5 is located by alignment pin 6 and by screw 7, is fixed on the end face of gripping section 4, and during location, pressing plate 5 compresses the rectangular end bottom of workpiece 1; Positioning disk 2 has rectangular through-hole 9 along axis direction, the structure of rectangular through-hole 9 is identical with the rectangular end of workpiece 1, be convenient to workpiece 1 to clamp, the bottom of rectangular through-hole 9 is with U-lag 8, the cylindrical of positioning disk 2 to through hole 9 has groove 3, make positioning disk 2 there is certain elasticity, when machine tool three-jaw chuck clamps, can clamp workpiece 1;

Using method of the present utility model is as follows:

The first step, in rectangular through-hole 9 on the rectangular end of workpiece 1 insertion positioning disk 2;

Second step, installation pressing plate 5 is on the end face of gripping section 4 and make it prop up the bottom of workpiece 1;

The 3rd step, is clamped in the gripping section 4 of positioning disk 2 on the scroll chuck of lathe;

The 4th step, carries out turning processing to the cylinder 11 of 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.
