Abstract
The utility model discloses a wire cutting machining device which comprises a clamp body, an index plate, a rotating shaft and a positioner. The index plate is movably arranged on the clamp body through the rotating shaft, the rotating shaft is arranged in the middle of the clamp body through a bearing, the positioner is fixedly arranged on the upper portion of the back face of the clamp body, and N rows of threaded locating pins are evenly arranged on the plate face of the index plate. In the using process, the clamp body is fixedly arranged on a workbench of a wire cutting machine, workpieces are screwed on the threaded locating pins, the locating pins of the positioner are inserted into locating holes, so that the index plate is positioned, the wire cutting machine is started, after through grooves in one direction are well machined, the index plate is rotated to be at a needed angle, and then through grooves in another direction are machined. The wire cutting machining device is capable of machining a plurality of nuts through one-time clamping, simple in structure, high in machining efficiency and particularly suitable for grooving machining of cross-shaped grooves in mother nuts of cone pressing embracing type self-locking stop nuts.
Description
Technical field
The utility model relates to a kind of processing unit (plant), is specifically related to a kind of wire electric discharge machine.
Background technology
It is the critical component using in modern electrification railway contact net that cone is pressed tight-holding type self locking anti-loose nut, has self-locking reliable, loads and unloads feature easy to maintenance.It is the vital part of realizing self-locking anti-loosing that cone is pressed the mother nut in tight-holding type self locking anti-loose nut, and cross recessed machining accuracy on part is related to the size of self-lock force, and therefore, cross recessed is processed into the critical process in mother nut processing.In order to guarantee cross recessed machining accuracy, line cutting fluting technology is widely used, although guaranteed machining accuracy, working (machining) efficiency is not high.Because, when line cutting fluting, in the situation that there is no special tooling, need first a nut to be located, process after a groove, by an angle of nut rotation, reprocessing another one groove, every handling once, can only be processed a workpiece.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one once can process multiple workpiece, and wire electric discharge machine simple in structure, working (machining) efficiency is high.
The purpose of this utility model is achieved in that a kind of wire electric discharge machine, comprise clamp body, index dial, turning cylinder and locator, it is characterized in that: described index dial is movably arranged on clamp body by turning cylinder, described turning cylinder is fixed on the middle part of clamp body by bearing, described locator is fixed on the top at the clamp body back side.
The middle part of described clamp body is provided with rotational axis hole, and top is provided with locator holes, and back is provided with reinforcement.
The middle part of described index dial is provided with rotational axis hole, and periphery is provided with at least one locating hole, and card is evenly provided with N row screw thread alignment pin.
The spacing of described screw thread alignment pin is 25～35mm.
When use, clamp body is fixed on the workbench of wire cutting machine, workpiece to be slotted is tightened on screw thread alignment pin, the alignment pin of locator inserts in the locating hole of index dial, index dial is located, start wire cutting machine, process after the groove of what a direction, pull locator, exit the alignment pin inserting in locating hole, index dial rotation, to required angle, behind location, is reprocessed to the groove of another direction.
Compared with prior art, the utility model is by changing the locate mode of multiple angles between index dial and clamp body, and clamped one time can be realized the processing of multiple workpiece, multiple angles groove, and not only positioning precision is high, and can realize production in enormous quantities, working (machining) efficiency improves greatly.

The specific embodiment
?the utility model is described in further detail by reference to the accompanying drawings for following examples.
The present embodiment is cross recess wire electric discharge machine.
Referring to Fig. 1, Fig. 2, a kind of cross recess wire electric discharge machine, comprise clamp body 1, index dial 2, turning cylinder 3 and locator 4, index dial 2 is movably arranged on clamp body 1 by turning cylinder 3, turning cylinder 3 is enclosed within bearing 5, and bearing 5 is fixed on the middle part of clamp body 1, and the two ends of bearing 5 are provided with nut 6 and adjust packing ring 7, nut 6 is fixing for turning cylinder 3, adjusts packing ring 7 for realizing the accurate rotation between index dial 2 and clamp body 1.Locator 4 is fixed on the top of clamp body 1.Locator 4 adopts hand pulling type spring space, and the alignment pin 41 of locator 4 is movably arranged in the pin-and-hole of locator 4.
Referring to Fig. 3, Fig. 4, the middle part of clamp body 1 has the rotational axis hole 11 for turning cylinder 3 is installed, and top has the locator holes 12 for installation positioner 4, and the back side is provided with reinforcement 13.
Referring to Fig. 5, Fig. 6, the middle part of index dial 2 has rotational axis hole 21, and top and a side have locating hole 22a and 22b, and the angle of cut of the horizontal center line of the vertical center line of locating hole 22a and locating hole 22b is 90 degree.The card of index dial 2 is evenly provided with N row screw thread alignment pin 23, and workpiece 8 is tightened on screw thread alignment pin 23.The numerical value of N is depending on the card size of index dial 2, and the spacing of every two screw thread alignment pins 23 is 25～35mm.The N of the present embodiment is 7 row, and spacing is 30mm.
The utility model also can be set to the locating hole of index dial 2 22 three or four, and the angle of every two locating hole 22 center lines is 60 degree or 45 degree, can be respectively used to the line cutting processing of three or four direction groove.
The utility model clamping once can be processed multiple nuts, and simple in structure, working (machining) efficiency is high, be specially adapted to cone and press mother nut cross recessed fluting processing in tight-holding type self locking anti-loose nut.
