Description
Technical field
The utility model belongs to mechanical frock field of fixtures, is specifically related to Linear cut technical field of tooling clamps, has the wire cutting machine frock clamp of the stock of axis hole especially.
Background technology
Line cutting technology utilizes the metal wire of movement to make tool-electrode, and pass to pulse current between metal wire and workpiece, utilizes the technology that the corrosiveness of pulsed discharge is cut workpiece.
In current line cutting technology, the location of Linear cut frock clamp to stock is more difficult, square cross stock 1 as shown in Figure 1 and Figure 2, it has the through wires hole 1-3 of aperture 1-1, axis hole 1-2 and Linear cut, this workpiece stock 1 to be processed the profile 2-1 concentric with aperture 1-1, axis hole 1-2 and form the workpiece 2 (as shown in Figure 3,4) of the profile of the figure of eight with profile 2-1, carry out adding there is following problem man-hour at employing wire cutting machine:
Due to location difficulty, the axiality of aperture 1-1, axis hole 1-2 and profile 2-1 is difficult to ensure, defective work is many, while causing workpiece to lose, also makes production efficiency low.
Utility model content
Technical problem to be solved in the utility model is: for above-mentioned Problems existing, there is provided a kind of structure simple, convenient to use, easily manufactured, and the Linear cut Special tooling clamp of converted products can be changed rapidly, adopt this Linear cut Special tooling clamp, accurate location and the compression of workpiece stock can be realized.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of Linear cut frock clamp, and it comprises base, hold down gag and loose pin, described base has the working hole passed for line of cut; The top of loose pin for insert workpiece stock axis hole in and with axis hole tight fit, the bottom of loose pin for insert in described working hole and with working hole tight fit, described hold down gag is for being pressed on base plate by workpiece stock.
In such scheme, Linear cut frock clamp also comprises fixed locating stud, and fixed locating stud is fixed on base, and fixed locating stud is used for the positioning end of positioning workpieces stock.
In such scheme, Linear cut frock clamp also comprises handle, and handle is fixedly installed on the lower end of loose pin.
The utility model compared with prior art has following beneficial effect:
1, the shaft hole matching owing to base being provided with loose pin and workpiece stock is located, and this just makes each workpiece stock position on base accurate, ensure that the precision performing wire cutting program processing profile.Hold down gag makes workpiece stock be pressed on base, makes workpiece stock can not produce displacement in process.
2, be provided with fixed locating stud to coordinate with an end face of workpiece stock, this just makes the position of each workpiece stock on base unified and unique simultaneously.
3, the lower end of loose pin is provided with handle, after hold down gag workpiece pressing stock, is conveniently extracted out below base by loose pin by handle.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Linear cut work piece holder shown in Fig. 5, Fig. 6, Fig. 7, it comprises base 3, hold down gag, fixed locating stud 5, handle 12 and loose pin 4, described base has the working hole 11 passed for line of cut; The top of loose pin 4 for insert workpiece stock 1 axis hole 1-2 in and with axis hole tight fit, the bottom of loose pin for insert in described working hole 11 and with working hole 11 tight fit, described hold down gag is used for workpiece stock 1 to be pressed on base plate 3.Fixed locating stud 5 is fixing on the base 3, and fixed locating stud 5 is for the positioning end 1-4 of positioning workpieces stock.Handle 12 is fixedly installed on the lower end of loose pin 4.
The operation principle of the present embodiment is:
First the axis hole 1-2 of workpiece stock 1 can be placed on base, and coordinate with activity orientation axle 4, the fixed locating stud 5 that the 1-4 location end face of workpiece stock 1 can be placed on base 3 coordinates, by workpiece stock 1 after base 3 is had good positioning, the carrying bolt 8 of adjustment hold down gag and and tight bolt 7, ensure that pressing plate 9 can parallel pressure be put at workpiece stock 1 upper surface, now, screw fastening screw nut 6, ensure that also tight bolt 7 can not rotate, after workpiece stock 1 upper surface reliably pushed down by pressing plate 9, screwing clamp nut 10 makes pressing plate 9 be pressed on base plate 3 by workpiece stock 1, now, by handle 12, loose pin 4 is extracted out below base plate 3.Linear cut metal wire is passed from through wires hole, carry out routine to heart operation, perform wire cutting program processing profile and press the processing of A-B-C-D-E-F-G-H-I path, Linear cut metal wire is at working hole internal cutting workpiece stock 1, after having cut, the workpiece 2 processed is taken out from workpiece stock 1.
Linear cut metal wire is extracted out from through wires hole, unscrewing clamp nut 10 makes pressing plate 9 unclamp from workpiece stock 1, workpiece stock 1 is taken off from base plate 3, loose pin 4 is turned back on base plate 3, another workpiece stock 1 to be processed again as previously discussed mode position, install, compress and process.
This fixture does not comprise the presser device this Linear cut work piece holder being fixed on wire cutting machine workbench.
