Description

A kind of milling self-align clamping device that floats

Technical field

The utility model belongs to the machining technique field, particularly relates to the unsteady self-align clamping device of a kind of milling.

Background technology

Automobile engine oil pump, because of the space structure demand, uses slim-lined construction to be connected with one-sided screw usually, has that material consumption is few, conveyer chain is short, low cost and other advantages.But at workpiece, add man-hour, clamping and location are difficult to meet efficient, low-cost requirement usually.Its conventional machining mode is: rough turn elongated cylindrical and workpiece and engine are installed end face; Utilize rough turn cylindrical and end face location, one-sided compression is carried out interior hole end surface processing; Its technique shortcoming is: 1, rough turn operation, as aided process, has increased the product processing cost; 2, cylindrical and locating hole fit clearance cause position error; 3, one-sided clamping causes workpiece to tilt, and after workpiece processing, wall thickness variation is large, and product strength reduces; 4, increase manpower, equipment, power consumption, production efficiency is low.

Therefore, design a kind of device that needs clamped one time just can complete the workpiece processing request and become this those skilled in the art's problem demanding prompt solution.

The utility model content

The purpose of this utility model just is to provide the unsteady self-align clamping device of a kind of milling, has realized that clamped one time just can complete the workpiece processing request, thereby has addressed the above problem fully.

The purpose of this utility model realizes by following technical proposals:

A kind of milling self-align clamping device that floats, comprise base, fixed head, actuating cylinder, unsteady briquetting and frock body, fixed head and frock body are installed on base, on the frock body, offer vertical through hole, along through hole, axially offer V-shaped groove, the inwall that through-hole wall is relative with V-shaped groove is laterally offered chute, and unsteady briquetting is slidably fitted in this chute, actuating cylinder is arranged on fixed head, and its piston rod end and unsteady briquetting are flexibly connected.

Further, the piston rod end of described actuating cylinder is connected with unsteady briquetting by universal ball end, thereby guarantees workpiece up and down producing balanced forces.

Further, described unsteady briquetting inwall and workpiece to be clamped outer wall shape are complementary.

Further, on described base, relative fixed head symmetry is installed two frock bodies, and the corresponding actuating cylinder of each frock body and a unsteady briquetting, offset the fixed head stress deformation, and non-cutting time is processed in shortening.

Compared with prior art, the beneficial effects of the utility model are:

1, efficiency is high: use blank directly to process, cancel roughing benchmark operation, enhance productivity; Large matched in clearance shortens clamping workpiece non-cutting time; The frock volume is little, is conducive to more multi-work piece of equipment workbench clamped one time, reduces the cutter changing amortization time; Processing accounting effective time increases substantially;

2, precision is high: gapless coordinates location, meets the requirement of workpiece machining high-precision;

3, workpiece deformation is little: float briquetting and workpiece profile uniformity, reduce the Workpiece clamping distortion;

4, labour intensity is low: the light clamping of workpiece, reduce operator's fruitless labour.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 be workpiece with the frock body on vertically through hole coordinate figure.

The specific embodiment

Below in conjunction with specific embodiments and the drawings, the utility model is further described.

as depicted in figs. 1 and 2, a kind of milling self-align clamping device that floats, comprise base 1, fixed head 2, actuating cylinder 3, briquetting 4 and frock body 5 float, fixed head 2 and frock body 5 are installed on base 1, on frock body 5, offer vertical through hole 6, along through hole 6, axially offer V-shaped groove 7, the inwall that through hole 6 inwalls are relative with V-shaped groove 7 is laterally offered chute, the briquetting 4 that floats is slidably fitted in this chute, and unsteady briquetting 4 inwalls and workpiece to be clamped 8 outer wall shapes are complementary, actuating cylinder 3 is arranged on fixed head 2, its piston rod end is flexibly connected by universal ball end 9 and unsteady briquetting 4, and universal ball end 9 parts embed in the briquetting 4 that floats.

For working (machining) efficiency further is provided, on described base 1, fixed head 2 is symmetrical relatively installs two frock bodies 5, or even many to frock body 5, each frock body 5 a corresponding actuating cylinder 3 and unsteady briquetting 4.

In use, workpiece 8 is put into to the vertical through hole 6 of frock body 5, workpiece 8 adopts large matched in clearance with this through hole 6, workpiece 8 relies on deadweight automatically to realize axial location, guarantee that workpiece 8 can put in place by rapid axial, actuating cylinder 3 drives the briquetting 4 that floats to V-shaped groove 7 direction workpiece pressings 8, and thrust makes workpiece 8 realize radially gapless location automatically.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
