Description

Technical Field

[0001] The present application relates to the field of wire cutting technology, and in particular to a wire cutting machine tool. Background Art

[0002] When machining parts, the workpiece is centered by a tool such as a tool or a centering rod. Centering is a common method of finding a reference and calibration. The existing centering method uses the original fixed plates on the machine tool, and one end of the two fixed plates is swung inward to the position between the two fixed plates, or one end of the two fixed plates is swung outward, so that the fixed plates of the machine tool are tilted, and then the workpiece is placed on the two fixed plates and fixed, and then the centering is performed.

[0003] A wire cutting centering device and a wire cutting machine tool mentioned in the existing Chinese public patent (authorization announcement number: CN213794661U) include a processing table, the top surface of the processing table is symmetrically provided with a slide rail, the middle part of the slide rail is provided with a notch arranged along the length direction of the slide rail, the top surface of the processing table is symmetrically provided with a support frame of an inverted U-shaped structure, the two bottom ends of the support frame cooperate with the corresponding slide rails, the middle part of the two bottom ends of the support frame passes through the notch and is fixedly connected with the threaded sleeve located below the processing table. In the utility model, a support frame is arranged on the processing table to support and fix the workpiece. When the first hand wheel is rotated, the first screw rotates, forcing the corresponding threaded sleeve to move, and the threaded sleeve is fixed to the support frame, so the support frames are close to or away from each other, and move synchronously to ensure that the workpiece is located in the middle of the processing table. In order to make the center of the workpiece coincide with the center of the processing table, the centering mechanism on the top surface of the support frame is used to perform centering adjustment again, so that the center of the workpiece coincides with the center of the processing table.

[0004] When cutting a workpiece, the workpiece is usually placed on a workbench for centering. However, most wire cutting centering devices on the market usually manually support the two ends of the workpiece after the workpiece is centered. However, manual support will cause uneven force on the workpiece, which may cause the workpiece to shift during cutting. Once the workpiece shifts, it will affect the accuracy of the cutting and thus affect the quality of the product. Utility Model Content
