Description
Technical field
The utility model relates to a kind of quick positioning fixture that is used on the numerically controlled wire cutting machine, especially can adapt to the positioning fixture of the same batch of workpiece with circle or square profile feature of the different sizes of processing.
Background technology
Numerically controlled wire cutting machine is to utilize the metal electrode silk to make the numerical control orbiting motion, under the effect of pulsed discharge ablation, reaches the processing method of cutting metal workpiece, is a kind of important manufacturing process of Precision Machinery Elements processing and mould manufacturing field.
Numerical Control Wire Cutting, because the track of wire electrode is controlled by numerical control program, its precision is guaranteed by the machining accuracy of equipment that the link that is easy to generate mismachining tolerance is the clamping and the centering operation of workpiece.Workpiece generally all adopts pressing plate to fix at the clamping of lathe, utilizes survey tools such as amesdial to carry out manual centering again, utilizes the contact centering program of lathe to find out the working origin of workpiece at last, just can carry out follow-up digital control processing.
In this centering process, operator's technical merit there is certain requirement, error is subjected to artificial factor bigger; Because each workpiece is all wanted clamping, centering, operation centering program, efficient is lower in reality processing, and uniformity is relatively poor in batches simultaneously.
The utility model content
Problem to be solved in the utility model is to provide a kind of quick positioning fixture that is used on the numerically controlled wire cutting machine, behind the location, processing need not to position once more operation, its positioning accuracy height with the circular or square workpiece of batch different sizes first, easy to operate, work efficiency significantly improves.
The utility model adopts following technical scheme, comprise U type support, slide block, screw mandrel governor motion, two arms of described U type support are provided with a pair of chute that matches with slide block, the middle part of described U type support is provided with the first V-type clamp port, and described slide block is provided with and the first V-type folder mouthful second corresponding V-type clamp port.Its principle is: earlier anchor clamps are connected to the lathe fixed position, after determining the origin of coordinates of anchor clamps, make the coordinate direction of anchor clamps consistent with the machine coordinates direction, rotate handwheel and drive the slide block slip by screw mandrel, workpiece is pressed between the first V-type clamp port and the second V-type clamp port, because the formed how much centering principles of two clamp ports, no matter how the profile size of round piece or square workpiece changes, and geometric center all is in the origin of coordinates position of anchor clamps behind clamping on the anchor clamps.
A kind of improvement is also to comprise: be located at the first data acquisition post A on the slide block along first coordinate direction
1With the second data acquisition post A that is located on the U type support
2, be located at the 3rd data acquisition post B on the U type support along second coordinate direction
1With the 4th data acquisition post B
2At first use the cutting silk and the first data acquisition post A of lathe
1With the second data acquisition post A
2A is determined in contact
1, A
2The center of contact is the zero point of first coordinate direction both; The cutting silk of lathe again with the 3rd data acquisition post B
1With the 4th data acquisition post B
2B is determined in contact
1, B
2The center of contact is the zero point of second coordinate direction both, determines the origin of coordinates of anchor clamps thus.Adopt this method to determine the origin of coordinates of anchor clamps, convenient and swift, accurate.
The another kind of improvement is that the described first V-type clamp port is identical with the shape and size of the second V-type clamp port, is symmetrical arranged up and down.
The utility model has following advantage:
1) during the manufacturing batch workpiece, only need operate and once find out lathe elements of a fix initial point, workpiece that can the batch machining different-diameter.
2) there is following geometrical relationship between round piece size and two contact A 1, the A2:
(constant value when C is jig Design).After finishing clamping workpiece, the distance of A1, A2, round piece diameter can intuitively be measured and obtain, and with the checking computations of data substitution relation formula, can in time find and correct the clamping mistake.
3) adopt these anchor clamps, have high production efficiency when the manufacturing batch product, the clamping facility is accurately dismantled in the workpiece location, and day converted products quantity has improved 3～5 times, and scrappage has reduced more than 10%.
4) these anchor clamps also can be applied to numerical control devices such as machining center, electric spark, CNC milling machine, can greatly enhance productivity when batch machining circle and square workpiece, reduce labour intensity and reduce the clamping error.
