Technical Field
[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a multifunctional clamp for wire cutting. Background Art
[0002] Wire cutting is the abbreviation of CNC EDM wire cutting, which is developed on the basis of EDM perforation and forming processing. The basic working principle of wire cutting is to use a moving metal wire as a tool electrode, pass a pulse current between the metal wire and the workpiece, and use the corrosion effect of the pulse discharge to cut the workpiece.
[0003] However, wire cutting often needs to cut workpieces of different shapes in daily work, so it is necessary to clamp workpieces of different shapes. When clamping the workpiece, there are mainly the following two problems:
[0004] 1. Currently, there are relatively few types of fixtures on the market, mainly pressure plates, G-shaped clamps, etc. Different fixtures need to be replaced when cutting workpieces of different shapes.
[0005] 2. When cutting workpieces with a certain angle, such as cutting a 60° V-groove, the clamps currently on the market do not have an angle adjustment function and cannot cut workpieces with angle requirements. Summary of the invention
[0006] In order to solve the defects and shortcomings of the prior art, the purpose of the utility model is to provide a multifunctional clamp for wire cutting, which can not only meet the needs of clamping workpieces of various shapes, but also realize the rotation of the workpiece at a specified angle, simplify the operation steps, reduce the difficulty of operation, and improve processing efficiency.
[0007] The utility model provides a multifunctional clamp for wire cutting, which includes: a right fastening screw hole of an upper pressure plate, an upper pressure plate, a left fastening screw hole of an upper pressure plate, a groove for clamping a workpiece on the upper pressure plate, a fixing hole of a clamp and a wire cutting machine, an angle plate, an angle pointer, a left fastening screw hole of a bottom plate, a bottom plate, a right fastening screw hole of a bottom plate, a groove for clamping a workpiece on the bottom plate, and a fastening screw. The upper pressure plate is a separate part that can be disassembled, and the two ends of the angle plate are respectively connected to the bottom plate and the clamp and the fixing hole of the wire cutting machine to form a component. The fastening screw passes through the right fastening screw hole of the upper pressure plate, the left fastening screw hole of the upper pressure plate, the left fastening screw hole of the bottom plate, and the right fastening screw hole of the bottom plate to press the upper pressure plate downward and clamp the bottom plate to form a clamp, and the fastening screw passes through the fixing hole of the clamp and the wire cutting machine to fix the clamp to the wire cutting machine, and the two ends of the angle plate are respectively connected to the fixing hole of the clamp and the wire cutting machine and the bottom plate. The upper pressing plate and the bottom plate are provided with grooves of various shapes, which are grooves for clamping the workpiece on the upper pressing plate and grooves for clamping the workpiece on the bottom plate. The rotation of the angle disk drives the bottom plate to rotate, and the angle pointer on the angle disk rotates accordingly.
[0008] The utility model has the following advantages:
[0009] (1) The technical solution adopted by the utility model to solve its technical problem is: a multifunctional clamp for wire cutting, including an angle device, an upper pressure plate, and a lower pressure plate. The upper and lower pressure plates are provided with a plurality of clamping grooves of different shapes, and fastening screw holes are provided at both ends. The angle device is rotatable and has a pointer.
[0010] (2) The upper and lower plates of the utility model clamp are provided with a plurality of clamping grooves of different shapes. When there are many types of workpieces to be processed and the shapes of the workpieces are diversified, they can be clamped through the different grooves on the upper and lower plates. Tightening and clamping are performed through the tightening screw holes. For example, cylindrical, square, triangular, polygonal, semi-cylindrical workpieces can all be clamped by this clamp, so that one clamp can clamp workpieces of various shapes.
[0011] (3) After the workpiece is clamped in the above manner, the angle device on the clamp of the utility model can be rotated to a specified angle by rotating the angle device and observing the angle disk and the pointer. Cutting of different shapes and angles can be achieved, which greatly reduces the difficulty of operation and improves processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
