Description

Technical Field

[0001] The utility model relates to a multi-head processing device of a numerical control engraving machine, belonging to the technical field of numerical control engraving. Background Art

[0002] In sculpture, carving refers to cutting or carving wood, stone or other materials into the desired shape. Previously, materials were cut manually using various workpieces. Now, the use of CNC engraving machines has greatly improved the efficiency and accuracy of carving. CNC engraving machines can perform relief, flat carving, hollow carving, etc. on aluminum alloys, copper, bakelite, wood, jade, glass, plastic, acrylic, etc., with fast carving speed and high precision.

[0003] The existing patent number is CN220535295U, which is a multi-head processing device for a CNC engraving machine. The device can drive the threaded sleeve to move inward by rotating the threaded rod, and the positioning plate can be driven to move inward by the movement of the threaded sleeve. The clamping rod can be driven to move inward by the movement of the positioning plate, and the clamping plate and the anti-skid pad can be driven to move inward by the movement of the clamping rod, so as to clamp and fix the workpiece. The anti-skid pad can be set to prevent the workpiece from sliding during the clamping process. The workpiece can be driven to move longitudinally by pulling the clamping rod upward, so that the operator can adjust the height of the processing surface according to the use requirements. The disassembly mechanism can be set to facilitate the operator. The staff can replace the processing head according to the use requirements, so as to use processing heads of different specifications and sizes to achieve different processing effects. However, when this device is in use, the positioning plate can clamp the workpiece through the rotation of the threaded rod, and the processing head rotates at one point, so that the engraving range is limited when engraving a larger workpiece, and the method of moving the workpiece up and down by pulling the clamping rod is not stable enough, which affects the processing accuracy of the processing head and reduces the processing effect; and although the workpiece can be kept stable by clamping the positioning plate, it is difficult to adjust the angle of the workpiece, so that the device can only process a single side of the workpiece, and cannot perform comprehensive engraving processing on the workpiece as required.
