CN2239315Y - NC linear cutting machine wire frame mutlifunctional device - Google Patents

Abstract

The utility model relates to a multifunctional device attached on an NC linear cutting machine wire frame, which is composed of a machine frame, a guide rail, a pulling plat, etc., wherein the machine frame is provided with a step-by-step motor, a carrier gear and a screw rod, and the screw rod drives the pulling plat through a screw cap of the screw rod to control the pulling plate to move up and down; the pulling plate is provided with a motor which can drive a main shaft to rotate. The device is suitable to be refitted or attached to all types of linear cutting machines, and the utility model makes the linear cutting machines changed from cutting planes and curved surfaces to cutting ball surfaces. When an electrode, a cutting tool or a chisel is arranged on a clamping head of the main shaft, the function of the original linear cutting machine can be kept, and the utility model can achieves multiple functions keeps at the same time.

Description

Nc wire-cutting guide frame multi-function device

The utility model relates to the multi-function device of a kind of attaching on the nc wire-cutting guide frame.

In the prior art, the planker of nc wire-cutting is two-dimentional, can only be used for plane or Machining of Curved Surface, and guide frame generally is to maintain static or only make wallowing motion, but instrument bevel, but must not process sphere.

The purpose of this utility model is to provide a kind of can move up and down the processing unit (plant) that also can rotate on guide frame, make wire cutting machine have three-dimensional planker, by cutting a hole at galvanic corrosion machine cuts or quarter, processes the workpiece of ganging up or not ganging up of plane, curved surface, sphere.

In order to achieve the above object, the utility model adopts following technical scheme: referring to Fig. 1, stepper motor (14) is housed on frame (5), at the stepper motor axle head motor tooth (11) is housed, motor tooth and inside and outside gap bridge tooth (10) (8) engagement, inside and outside gap bridge tooth size is identical, with going here and there on a gap bridge tooth axle (7), gap bridge tooth axle is fixed on the frame, gap bridge tooth and screw gear (12) engagement that is fixed on the screw mandrel (13), and screw mandrel also is contained on the frame.Guide rail (6) is fixed on the frame, and screw mandrel nut (3) is housed on the screw mandrel, and screw mandrel nut one side is embedded in the planker (16), and planker can slide on guide rail.Stepper motor, the motor tooth, the gap bridge tooth, screw gear, screw mandrel, the screw mandrel nut, guide rail and planker form one can control the transmission system that planker moves up and down.Main shaft (2) is housed on the planker, and the main shaft upper end connects with main motor (1), and chuck (4) is equipped with in the main shaft lower end, and main shaft is rotated by main driven by motor.Can press from both sides electrode or cutter on the chuck.Torsion spring (9) is housed between the gap bridge tooth inside and outside two, and it makes inside and outside gap bridge tooth produce the opposite torsion that rotates, and to eliminate the back lash between motor tooth (11) and the screw gear (12), improves the transmission accuracy between screw mandrel and the motor shaft.

During use, line cutting cross saddle moves as the plane, multi-function device on the guide frame can be according to the workpiece needs, make planker (16) do corresponding up and down moving by electricity instruction operation stepper motor, electrode on the chuck or cutter just can process the shape of ganging up or not ganging up of corresponding plane, curved surface, sphere on workpiece.

The utility model compared with prior art, it is wide to have the scope of application, easy to operate, precision machining, the advantage that function is many.

The drawing explanation of accompanying drawing:

Fig. 1 is the structure principle chart of the utility model embodiment.

Embodiment of the present utility model is: referring to Fig. 1, (1) be main motor, (2) are main shafts, and (3) are the screw mandrel nuts, (4) be chuck, (5) be frame, form by two that (6) are guide rails for easy to process, (7) be gap bridge tooth axle, (8) be outer gap bridge tooth, (9) are torsion springs, and (10) are interior gap bridge teeth, (11) be the motor tooth, (12) be screw gear, (13) are screw mandrels, and (14) are stepper motors, (15) be handle, one end connects with screw mandrel, is to make manual operation planker (16) to move up and down usefulness, and (16) are plankers.

Claims (2)

1, a kind of nc wire-cutting guide frame multi-function device, comprise a main motor and by the main shaft of its drive, chuck is equipped with in the main shaft lower end, main shaft is contained on the planker, planker and guide rail join, driving it by screw mandrel by the screw mandrel nut moves up and down, after a stepper motor slows down by the gap bridge tooth, the drive screw mandrel rotates, screw mandrel and stepper motor are contained on the frame, guide rail is fixed by frame and guide frame, it is characterized in that stepper motor, gap bridge tooth, and screw gear, screw mandrel, screw mandrel nut, guide rail and planker form a transmission system that the control planker is moved up and down; Main motor, main shaft and chuck form a rotation work system.

2, guide frame multi-function device according to claim 1, its feature tooth that also is to pass a bridge is made up of on same gap bridge tooth axle axle identical inside and outside two the gap bridge tooth strings of size, a torsion spring is housed between two gap bridge teeth, makes inside and outside gap bridge tooth produce the opposite torsion that rotates.
