Abstract

The invention relates to a lathe positioning fixture comprising a positioning disc. The positioning disc is fixedly connected with two counterbalances and a positioning seat. The positioning seat is provided with a V-shaped groove, and is fixedly connected with a pressing block with an arc groove. A positioning pin is arranged, at one end of the positioning seat, on the positioning disc. The two counterbalances are symmetrical around the axis of the V-shaped groove. The lathe positioning fixture has the advantages of simple structure, flexibility and convenience in use, clamping easiness and high machining precision.

Description

Turner positioning fixture
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to for workpiece being carried out to the positioning fixture of Drilling operation.
Background technology
Workpiece 1 as shown in Figure 1, it has a rectangular end and cylindrical section, according to specification requirement, now need to the through hole 11 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-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.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of turner positioning fixture is provided, it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.
The technical solution adopted in the present invention 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 with alignment pin on positioning disk, balance weight is two and symmetrical about the axis of V-shaped groove.
The invention has the advantages that: 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 invention.
Fig. 3 is use state diagram of the present invention.
The specific embodiment
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 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, the cylindrical section of deep-slotted chip breaker 8 and 6 pairs of workpiece 1 of V-shaped groove carries out clamping and positioning, 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 symmetrical about the axis of 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 invention 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 explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
