It is widely used in the processing of various precision parts. During wire cutting machine processing, a certain discharge gap is always maintained between the electrode wire and the workpiece. When the pulse current generated by the pulse power supply passes through the electrode wire and the workpiece, an instantaneous high temperature is generated in the discharge gap, causing the workpiece material to partially melt and vaporize, thereby achieving cutting of the workpiece.

In order to clamp and center the workpiece, a slidable clamping arm 33 is provided on the front and rear sides of the top of the displacement processing table 2, and a rectangular slide 34 is provided on the front and rear sides of the top of the displacement processing table 2 to match the clamping arm 33. A driving component 4 is provided on the left side of the inner cavity of the displacement processing table 2. The driving component 4 includes a stepper motor 41 fixedly mounted on the left end of the rear side of the displacement processing table 2. A worm 42 is rotatably connected to the left side of the inner cavity of the displacement processing table 2. The output shaft of the stepper motor 41 passes through the inner cavity of the displacement processing table 2 and is fixedly connected to the rear end of the worm 42. The left end of the rotating column 31 on the rear side is fixedly connected to The worm gear 43, the worm 42 and the worm gear 43 are meshed with each other, and the right end of the rotating column 31 is fixedly connected to a synchronous gear 44. The two synchronous gears 44 are meshed with each other. Through the arrangement of the drive assembly 4, under the drive of the stepping motor 41, the worm 42 and the worm gear 43 are used in conjunction with each other, the rotating column 31 located at the rear side is driven to rotate. At the same time, under the cooperation of the two synchronous gears 44, the two rotating columns 31 can simultaneously rotate in opposite directions or opposite directions, thereby enabling the two propulsion gears 32 to simultaneously rotate in opposite directions or opposite directions, thereby driving the rack 35 and the clamping arm 33. The inner cavity of the table 1 is provided with a distance adjustment and alignment component 5, which includes a threaded sleeve 51 fixedly connected to the bottom of the displacement processing table 2. A rectangular slide groove 2 52 adapted to the threaded sleeve 51 is provided at the bottom of the inner cavity of the base 1. The rear side of the inner cavity of the rectangular slide groove 2 52 is rotatably connected to a threaded push rod 53 through a bearing. The threaded sleeve 51 is threadedly connected to the surface of the threaded push rod 53.

[0024] Working principle: When the present invention is used, the user first places the workpiece on the top of the displacement processing table 2, and then turns on the stepper motor 41. The stepper motor 41 starts and drives the worm 42 to rotate. Due to the meshing action of the worm wheel 43 and the worm 42, the rotating column 31 located at the rear side rotates. During the rotation process, the rear rotating column 31 is meshed with the two synchronous gears 44 to drive the two rotating columns 31 to rotate toward each other. During the rotation process, the rotating column 31 drives the propulsion gear 32 to rotate. Due to the meshing action of the propulsion gear 32 and the rack 35, the two racks 35 slide toward each other and drive the two clamping arms 33 to move toward each other, so that the workpiece can be clamped. 33 The movement stroke and time are the same, so that the center position of the workpiece and the indicator arrow 54 are on the same horizontal line. Then the user shakes the handwheel on the front side of the threaded push rod 53 according to the cutting entry position of the workpiece, so that the threaded push rod 53 rotates. During the rotation, the threaded push rod 53 pushes the threaded sleeve 51 through the thread on its surface. During the movement, the threaded sleeve 51 drives the displacement processing table 2 to slide in the inner cavity of the base 1. During the sliding process, the displacement processing table 2 drives the indicator arrow 54 to move, so that the indicator arrow 54 indicates the scale 55 at the position determined by the user. The position indicated by the indicator arrow 54 is the entry position of the wire cutting equipment on the other side of the workpiece.

[0025] To sum up: the precise positioning device of the wire cutting machine tool, through the coordinated use of the displacement processing table 2 and the center positioning component 3, performs center positioning on the workpiece and clamps the workpiece, and then, through the coordinated use of the base 1 and the distance adjustment positioning component 5, accurately adjusts the cutting position of the workpiece, and finally performs wire cutting on the extended position of the workpiece, thereby achieving the purpose of automatic center positioning clamping and facilitating precise adjustment of the cutting position.
