Description
Technical field
The utility model belongs to field of machining, is related to a kind of numerical control built-up jig.
Background technique
Current some factories process part with conventional equipment, generally use traditional processing technology, more complex when applying to
Workpiece especially the processing of shape irregular part when, be not just very effectively, also often occur non-cutting time is long, process is tedious,
The phenomenon that workpiece configurations and scale error do not meet drawing requirement, precision cannot ensure, impact to production.Such as with draw
The direct centering location of workpiece of the tools such as needle, the dial gauge and method clamped claims direct centering Method for Installation, productivity is low, precision
Depending on the technical level of worker and the precision of measuring tool；Or the position for wanting finished surface is first drawn with scriber, then by scribing line
With position of the scriber centering workpiece on lathe and clamped, router that is time-consuming, and needing technology high.
Summary of the invention
In view of the problems of in the prior art, the utility model discloses a kind of numerical control built-up jig, grip devices
On the 4th axial-rotation dividing head of numerically-controlled machine tool, rotary index head precision 0.005mm Max passes through amesdial clamping fixture for correcting device
Position degree.By clamping fixture seat positioning key, workpiece is placed and is cooperated, tolerance fit gap 0.005mm Max reuses screw and passes through
Fixation is pushed down in workpiece two sides by cover board and clamping fixture seat, and numerically-controlled machine tool milling cutter avoids product activity in the processing that runs at high speed and makes
At mismachining tolerance, and clamping fixture seat can be replaced according to the difference of workpiece.
The technical solution adopted by the present invention is that: a kind of numerical control built-up jig, including pedestal, clamping fixture seat, gland, pedestal installation
It further include base aperture on the 4th axial-rotation dividing head of numerically-controlled machine tool, support column, pin hole, screw, positioning pin, positioning key adds
Solid hole I, reinforced hole II；4 base apertures are wherein provided on pedestal, screw passes through base aperture and pedestal is fixed on numerically-controlled machine tool,
One cylindrical support column is housed, support column center is provided with reinforced hole I, has pin around support column bottom in base-plates surface in the middle part of pedestal
Hole, on the support columns, clamping fixture seat top is provided with hole corresponding with pin hole to fixture cover for seat, and positioning pin is worn to pin hole from hole by fixture
Seat is fixed on the base, and positioning key that protrusion is arranged at clamping fixture seat top, mutually agreeing with workpiece bottom, gland is mounted on workpiece top
Portion, gland middle part are provided with reinforced hole II, are linked together using screw by reinforced hole II and the reinforced hole I of support column, with folder
Has seat together by Workpiece clamping.The clamping fixture seat can be replaced according to the difference of workpiece demand.
Working principle of the utility model is:
Pedestal 1 is mounted on the 4th axial-rotation dividing head of numerically-controlled machine tool using screw 5 by base aperture 2, rotary index head
Precision 0.005mm Max, by amesdial clamping fixture for correcting setting position degree, 7 sets of clamping fixture seat on support column 3, utilize positioning pin 6
Clamping fixture seat 7 is fastened on pedestal 1 across pin hole 4, using the positioning key 8 of 7 upper ledge of clamping fixture seat, workpiece is placed and is cooperated,
Tolerance fit gap 0.005mm Max. reuses screw and passes through the reinforced hole II 11 at 9 center of gland and the reinforced hole I of support column 3
Workpiece two sides are pushed down and are fixed between gland 9 and clamping fixture seat 7 by 10, and numerically-controlled machine tool milling cutter avoids in the processing that runs at high speed
Product activity causes mismachining tolerance.
The utility model has the beneficial effects that
1, fixture has adjusted good position on lathe in advance, it is no longer necessary to and Workpiece clamping can be simplified process by centering,
Working hour is shortened, to the full extent；2, by the tool setting device on fixture, it ensure that workpiece machining surface relative to cutter just
True position.Error caused by avoiding manually.3, it can be realized between numerical control clamp according to the different replacement clamping fixture seats of work pieces process demand
Combination.
