Workpiece rotating device for numerical control engraving machine

Abstract

The invention discloses a workpiece rotating device for a numerically controlled engraving machine, which comprises a workbench, a rotating tray is arranged on the upper end of the workbench, and an annular block is fixedly connected to the bottom edge of the rotating tray, and the upper end of the workbench The inner wall is provided with an annular clamping groove corresponding to the annular clamping block, and a weight sensor is installed at the center of the bottom wall of the clamping groove, and several driving devices are uniformly surrounded on one side of the inner wall of the clamping groove, and the driving device is installed There is a controller, one side of the driving device is provided with a telescopic rod, and the end of the telescopic rod away from the driving device is fixedly connected with a fixed plate, and the outer wall side of the fixed plate is fixedly connected with a clamping plate through several springs, so The bottom wall of the rotary tray is fixedly connected with a connecting shaft. The invention is simple in structure and easy to operate, and can carry out rotary engraving after the workpiece is fixed, improves the efficiency and quality of workpiece processing, and satisfies the needs of workpiece processing.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a workpiece rotating device for a numerically controlled engraving machine. Background technique [0002] Engraving is a combination of drilling and milling in terms of processing principle. Engraving machines can be divided into two types: laser engraving and mechanical engraving. Mechanical engraving machine is a general-purpose mechanical equipment widely used in wood industry, advertising industry, craft industry, mold industry, construction industry, printing and packaging industry, decoration industry, it can carve wood board, density board, acrylic organic board, PVC board and other different Material, in the process of engraving the workpiece, the machine tool is generally used to finish the mechanical workpiece. According to the needs of mechanical workpiece processing, the workpiece placed on the processing platform needs to be rotated so that the machine ...

Mechanical engraving machine is a general-purpose mechanical equipment widely used in wood industry, advertising industry, craft industry, mold industry, construction industry, printing and packaging industry, decoration industry, it can carve wood board, density board, acrylic organic board, PVC board and other different Material, in the process of engraving the workpiece, the machine tool is generally used to finish the mechanical workpiece. According to the needs of mechanical workpiece processing, the workpiece placed on the processing platform needs to be rotated so that the machine tool can process the workpiece conveniently. , the existing workpiece rotating processing device has a complex structure and troublesome operation. In the process of fixing the workpiece, two clamping plates or fixing blocks are generally used to fix the workpiece. The existing clamping plates and fixing blocks are both Manual operation is required, which greatly increases the work intensity of the workers and reduces the processing efficiency of the workpiece during the process of fixing the workpiece. Moreover, when the existing workpiece needs to be rotated during the processing process, the workpiece is generally fixed by a fixing mechanism. Loosen, manually rotate the workpiece and then use the fixing mechanism to fix the workpiece. Due to the large volume and heavy weight of the mechanical workpiece, it is difficult for the worker to rotate the workpiece conveniently, and because the workpiece is rotated manually, during the rotation process It is difficult to ensure accuracy and stability in the process, which will reduce the efficiency and quality of workpiece processing, and it is difficult to meet the needs of workpiece production and processing
