Description
Technical field
The present invention relates to automated machine apparatus field, specially a kind of Workpiece clamping for automating processing wire cutting machine
Mechanism.
Background technology
Mainly by lathe, digital control system and high frequency electric source, this three parts forms wire cutting machine.Digital control system is by single-chip microcomputer, key
Disk, frequency conversion detecting system are formed, and there is backlash compensation, linear interpolation, circular interpolation, fracture of wire the major function such as to automatically process.Energy
Cutting material, such as high intensity, high tenacity, high rigidity, high fragility, magnetic material, and accurate tiny and complex-shaped part.
Line cutting technology, wire cutting machine tool are just widely used in all trades and professions.One of strength member as wire cutting machine
Fixture it is also particularly important.
Existing wire cutting machine fixture have the following disadvantages and problem：
(1) most of wire cutting machine fixture many at present makes clamp workpiece, hand Screw by screwing bolts
Not only clamp speeds delay man-hour to bolt slowly, and fixture easily because bolt gets rusty, sliding tooth and caused by clamping force it is inadequate, clamp not
The problems such as stable, and if stubborn not tight enough of bolt, workpiece easily loosens when processing, and processing is unstable, if bolt is twisted too
Tightly, the damage of workpiece surface is easily caused；
(2) fixture of current wire cutting machine is usually the workpiece that can only press from both sides similar shape, than if the work of clamping plate bulk
The fixture of part cannot clamping bar shape or tubulose workpiece, the work piece holder folder shaft that allow clamping plate block just must be added with groove
Cushion block, increase labour, and cushion block is also easy to slide, and applicable surface is narrow, and groove of the fixture of clamping bar shape because placing bar
Smoother, workpiece and fixture easily loosen because of vibration on lathe, and workpiece processing quality is unqualified；
(3) the upper and lower clip-on fixture of wire cutting machine is when pressing from both sides cylindrical bar, because groove typically than cylindrical bar side big, cylinder
Bar is placed on groove and easily rolled, and when upper grip is clipped in lower chuck, cylindrical bar as extruding force and change position
Put, can not thus realize accurate processing and cutting to cylindrical bar, clamping stabilization time is longer, and processing efficiency is low.

Embodiment：
As shown in figure 1, the invention provides a kind of workpiece clamping mechanism for automating processing wire cutting machine, including base
1, the bottom center of base 1 is provided with square hole 13, and square opening 13 is used for the chip after making workpiece cut and dropped on workbench, prevents
Only chip drops on base 1 and causes the difficult consequence cleared up, and the bottom surface both sides of base 1 are provided with fixing hole 14, and fixing hole 14 has
There is internal thread, fixed base 1 on the table by the can of bolt precession fixing hole 14.
As shown in figure 1, the top surface both sides of base 1 are installed with holder 2, the top surface of base 1 and holder 2 are all provided with
There are circular hole 3, the circular hole 3 of the base 1 and the location matches of circular hole 3 of holder 2, hydraulic stem 6 is smoothly inserted circular hole, hydraulic stem 6
The top surface of holder 2 is stretched out on head, to facilitate chuck 8 in the surface upper and lower displacement of holder 2.The inside of base 1 is provided with installation room 4,
The normal cross-section of the installation room 4 is shaped as inverted T-shaped, makes that base top surface will not be switched to when wire cutting machine cutting workpiece, more surely
It is fixed.The installation bottom left of room 4 and right side are installed with hydraulic cylinder 6 by mounting seat 5, and the hydraulic cylinder 6 is connected with
Hydraulic stem 7, the hydraulic stem 7 insert circular hole 3, the hydraulic stem 7 and horizontal plane, and hydraulic cylinder 6 drives hydraulic stem 7 to do vertically
Stretching motion on face and chuck 8 is clamped or loosen workpiece, control chuck 8 tightly to clamp workpiece by the contraction of hydraulic stem 7,
It is reliable and stable to clamp quick and clamping force, processing is more stable.
It should be added that the hydraulic cylinder 6 described in the above does not do specifically limited, in the present invention, may be used also
The equipment such as 6 functionally similar pneumatic cylinder of hydraulic cylinder are used in be controlled.
As shown in figure 1, the top of hydraulic stem 7 is installed with chuck 8, the chuck 8 is located at directly over holder 2, institute
State the top surface of chuck 8 and the bottom surface of holder 2 and plane-parallel, chuck 8 is under the oppressive force of workpiece when hydraulic stem 7 rises
Drop, clamping force decline, and chuck 8 is gradually increasing to the oppressive force of workpiece when hydraulic stem 7 declines, clamping force increases.The folder
First 8 bottom surface and the top surface of holder 2 are mounted on abrasion-proof rubber cushion 9, and the thickness of abrasion-proof rubber cushion 9 is 0.2-0.8mm, both ensure that clamping
Power, also protects chuck 8 and workpiece, and the abrasion-proof rubber cushion 9 on chuck 8 and holder 2 not only makes the rigid thrust that workpiece is subject to
Reduce and protect workpiece, the frictional force between workpiece and fixture can more increased, workpiece is not slided during being processed, add
Work process is more stable.
As shown in Figure 1, Figure 2 and Figure 3, the bottom surface of chuck 8 and the top surface of holder 2 are equipped with some grooves 10, the chuck 8
Groove 10 and holder 2 the location matches of groove 10, the cooperation of lower notches 10 makes clamping force more stable, and the groove 10 includes
