Description

TECHNICAL FIELD

[0001] The utility model relates to metal carving equipment technical field, especially relates to a metal carving machine. BACKGROUND

[0002] With the continuous progress of science and technology, mechanical processing technology is gradually applied to the field of metal carving. Early metal carving machines use simple mechanical transmission structure, and the cutter is driven to rotate by a motor to cut and carve the metal. Compared with manual carving, this kind of machine improves the carving efficiency to a certain extent and can realize some relatively regular carving patterns.

[0003] However, the precision and flexibility of the carving are still limited, which is difficult to meet the needs of complex and delicate carving. At the same time, the operation of this kind of machine is relatively complex, which needs professional operators to debug and control, increasing the use cost and technical threshold. In recent years, with the rapid development of computer technology, numerical control technology and advanced sensor technology, numerical control metal carving machine emerges as the times require. The numerical control metal carving machine can realize high-precision, high-efficiency and high-flexibility metal carving processing by controlling the motion trajectory and carving parameters of the cutter through computer program. It can accurately perform various complex carving operations on the metal surface according to the designed digital pattern, and can easily cope with text, patterns and three-dimensional modeling. The numerical control metal carving machine also has the advantages of high automation and simple operation. The operator only needs to input the designed program into the machine to realize automatic carving, which greatly reduces the labor intensity and the requirement for the technical level of the operator.

[0004] In the patent with application number CN201821954252.8, a metal carving machine is provided, which includes a support plate, a basket, a gantry, a carving device, a workbench, a clamping plate, a rotating wheel, a mounting bracket, an electric push rod, a collection basket and a short shaft. The carving device is installed on the gantry, the support plate is fixed in the middle part of the basket, the mounting bracket is connected to the left end of the lower side of the workbench, the short shaft is fixed in the mounting bracket, the rotating wheel is installed on the ring-shaped side of the short shaft, the electric push rod is fixed to the right side of the basket inside the workbench on the upper side, the clamping plate is connected to the left end of the electric push rod, the square hole is opened in the lower end of the rear side of the basket, and the collection basket extends to the inside of the square hole. This design realizes the fixation of the metal plate.

[0005] However, the above design still has some shortcomings: 1. When clamping and fixing the metal parts to be processed, it cannot form an effective fixing reference; 2. It cannot be flexibly adjusted according to different shapes and sizes of metal materials, so that the clamp can be suitable for different shapes of metal parts to be processed.

[0006] Therefore, there is an urgent need for a metal carving machine that is accurate in positioning, flexible in use, widely used in processing and reduces the difficulty of operation. Utility Model Content

[0070] like Figures 1 to 12 As shown, a metal engraving machine includes a worktable 1 and an engraving mechanism 2;

[0071] The workbench 1 is horizontally arranged and includes a base 11 and a loading platform 12. The base 11 is square-shaped. The loading platform 12 is slidably adjustable along the longitudinal direction of the workbench 1. A clamping platform 3 is installed on the loading platform 12. Two sets of symmetrical clamps 30 are arranged along any diagonal of the clamping platform 3. The clamps 30 are slidably adjustable along the diagonal of the clamping platform 3. When the clamps 30 are closed, they confine the metal part to be processed to the center position of the clamping platform 3.

[0072] The engraving mechanism 2 is installed directly above the workbench 1. The engraving mechanism 2 includes an engraving machine 21, a horizontal moving module 22, and a lifting module 23. The horizontal moving module 22 drives the engraving machine 21 to move horizontally along the workbench 1, and the lifting module 23 drives the lifting module 23 to move vertically.

[0073] It should be noted that the clamping platform 3 of the present application is detachably arranged on the material loading table 12. Specifically, the clamping platform 3 can be installed on the material loading table 12 by means of electromagnetic adsorption or threaded fastening. For regular square, circular, oval, hexagonal and other metal workpieces, the clamping platform 3 is arranged in a square shape. For rectangular metal workpieces, the clamping platform 3 can be arranged in a profiled rectangular shape, preferably so that the diagonal of the metal workpiece coincides with the diagonal of the clamping platform 3, thereby achieving precise centering.
