The invention provides a workpiece automatic clamping device, a workpiece automatic clamping method, a workpiece cut-off equipment and a workpiece cut-off method. The workpiece automatic clamping device comprises a bearing base and workpiece clamping jigs which are hinged to the bearing base and used for clamping and positioning a to-be-cut workpiece after the to-be-cut workpiece is located on the bearing base. By means of the workpiece automatic clamping device provided by the invention, the workpiece clamping jigs on the two sides are pressed on the basis of the self weight of the to-be-cut workpiece according to the lever principle, so that the workpiece clamping jigs on the two sides squeeze towards the middle and abut against the to-be-cut workpiece so that the to-be-cut workpiece can be squeezed towards the middle, thus, the to-be-cut workpiece is located in the center position, and the position of the to-be-cut workpiece is stable; accordingly, the effect that the to-be-cut workpiece is stably positioned without shifting and jumping in the cutting process is ensured, and the situation that a cut surface is out of flatness, and the workpiece is collided due to dumping of broken edge materials or marginal materials is avoided; and the cutting quality and the cutting efficiency of the workpiece are improved.
Description
Technical field [0001] The invention relates to the field of cutting, in particular to a workpiece self-clamping device and a self-tightening method, a workpiece cutting device and a cutting method. Background technique [0002] Wire cutting technology is currently the world’s most advanced square-cutting processing technology. Its principle is to realize workpiece cutting by rubbing the workpiece (such as silicon rod, sapphire, or other semiconductor hard and brittle materials) with a high-speed moving gold steel wire. . Wire cutting technology has the advantages of high efficiency, high productivity, and high precision compared with traditional blade saw blades, grinding wheel blades and internal circular cutting. [0003] In terms of polycrystalline silicon rod truncation, in the prior art, the polycrystalline silicon rod to be cut is placed on a carrying table, and the cutting unit cuts the polycrystalline silicon rod carried on the carrying table. However, in practical applic...
