Abstract

The utility model relates to a turning positioning clamp, which comprises a positioning disc, wherein the positioning disc is fixedly connected with two balance blocks and a positioning seat, a V-shaped groove is formed in the positioning seat, a press block with an arc-shaped groove is fixedly connected onto the positioning seat, one end, positioned at one end of the positioning seat, on the positioning disc is provided with a positioning pin, and the two balance blocks are symmetrical by using the axial line of the V-shaped groove as the symmetry axis. The turning positioning clamp has the advantages that the structure is simple, the use is flexible and convenient, the installation and the clamping are simple, and the processing precision is high.

Description

Turner positioning fixture

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 Drilling operation.

Background technology

Workpiece 1 as shown in Figure 1, it has a rectangular end and cylindrical section, according to technical requirement, now need to the through hole on rectangular end, carry out fine finishining to rectangle, use plain clamp to acquire a certain degree of difficulty to its location, especially to guarantee machining accuracy, must use special frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee again its machining accuracy simultaneously.

Utility model content

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

Turner positioning fixture, comprises positioning disk, and positioning disk is fixed with balance weight and positioning seat, on positioning seat with V-shaped groove, on positioning seat, be fixed with the briquetting with deep-slotted chip breaker, be positioned at one end of positioning seat 5 with alignment pin on positioning disk, balance weight is two and the axis symmetry about V-shaped groove.

The utility model has the advantage of: according to the concrete structure of workpiece, the positioning seat matching with workpiece is set on positioning disk, and uses the briquetting with deep-slotted chip breaker that the cylindrical section of workpiece is clamped, and use alignment pin to prop up from the bottom of workpiece, while preventing high speed rotating, workpiece departs from frock, is equipped with balance weight simultaneously on positioning disk, more steady while making positioning disk high speed rotating, be beneficial to the turning accuracy that guarantees 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 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, positioning disk 2 is fixed with balance weight 3 and positioning seat 5, on positioning seat 5 with V-shaped groove 6, on positioning seat 5, be fixed with the briquetting 7 with deep-slotted chip breaker 8, deep-slotted chip breaker 8 and V-shaped groove 6 carry out clamping and positioning to the cylindrical section of workpiece 1, on positioning disk 2, be positioned at one end of positioning seat 5 with alignment pin 4, rectangular end on can workpiece carries out spacing to workpiece, prevent that workpiece from departing from positioning seat 5 when high-speed turning, balance weight 3 is two and the axis symmetry about V-shaped groove 6, can guarantee that positioning disk 2 keeps balance when high-speed turning, and then the machining accuracy while guaranteeing fine finishining through hole 11,

Using method of the present utility model is as follows:

The first step, is placed in the cylindrical section of workpiece in the V-shaped groove 6 of positioning seat 5;

Second step, is used briquetting 7 to be fixed on the cylindrical section to workpiece on positioning seat 5 and clamps;

The 3rd step, guarantees that alignment pin 4 props up the bottom of rectangular end on workpiece;

The 4th step, is clamped in positioning disk 2 on the scroll chuck of lathe;

The 5th step, carries out fine finishining to the through hole on the rectangular end of workpiece.

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.
