The outfit of the work that line cut processes is placed and adjust

1, the outfit clip of workpiece

When the workpiece that hold clip, the cut place that must assure workpiece is located in machine tool workbench in the limit of fore-and-aft, transverse feed, avoid to exceed the limit. Should consider space of motion of silk of the electrode when cut at the same time. Clamping apparatus should choose as far as possible general (or standard) , place choosing clamping apparatus should facilitate outfit clip, facilitate the dimension of harmonious workpiece and machine tool concerns. When machining large mould, want special attention the orientation way of workpiece, when machining swift end especially, of workpiece be out of shape, gravitational action can make electrode silk by clamp, influence treatment.

(1) cantilever type holds clip
Like the graph 6.2 are shown is workpiece of clip of cantilever means outfit, outfit of this kind of means places convenient, versatility strong. But because workpiece one aspect of the matter is dangerous,extend, on surface of easy occurrence cut and workpiece, the verticality error between next plane. Use at the circumstance that treatment asks not tall or cantilever is shorter only.
(2) two end prop up means to hold clip
Like the graph 6.3 are shown is workpiece of clip of outfit of the two end means that prop up, outfit of this kind of means places convenient, stability, fixed position precision is tall, but unwell place larger part at installing.
(3) the bridge-type means that prop up holds clip
This kind of means is after mat iron is placed on general clamping apparatus reload places workpiece, if pursue,6.4 are shown. This kind of means installs clip to go to the lavatory, can use to big, medium, small-sized workpiece.

Graph 6.2 cantilever type holds clip

Graph outfit of the means of 6.3 two end that prop up places a figure 6.4 bridge-type go maintaining means to hold clip

(4) the board type kind that prop up holds clip
If the graph is shown 6.5 times,be workpiece of clip of outfit of the board type kind that prop up. According to commonly used workpiece appearance and dimension, use the gripper shoe that has via to hold clip work. Precision of clip of outfit of this kind of means is tall, but versatility is poor.

2, the adjustment of workpiece

Use above means to hold clip work, still must cooperate to look for execute to undertake adjustment, just can make the fixed position datum plane of workpiece parts the feed direction X of the working mesa with the machine tool and workbench, Y keeps parallel, in order to assure the relative position precision between the surface of a cut and datum plane. Look for square law commonly usedly to have:
(1) search with dial gauge
If the graph is shown 6.6 times, secure dial gauge with magnetic force dial framework in filar wearing or other locally, the measurement of dial gauge head and workpiece radical surface contact, reciprocating translation workbench, adjust the position of workpiece by dial gauge indicated value, till of dial gauge finger slant the numerical value that places limits to achieve a requirement. Search to answering to undertake on 3 mutual and perpendicular direction.
