Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of jade carving, and particularly relates to a Shoushan stone automatic carving device. BACKGROUND

[0002] The Shoushan stone carving device is a numerical control equipment specially used for carving Shoushan stone and other jade materials, and is combined with precision machinery, servo control and software compatibility, and is suitable for fine carving requirements of handicrafts, seals, inkstones and the like. The Shoushan stone carving device has high carving precision requirements, adopts a cast iron bed body and a ball screw transmission, effectively reduces vibration, and ensures the stability of the movement of the workbench; is provided with a variable frequency main shaft, supports air cooling or water cooling selection, realizes accurate stroke control through a servo motor or a stepping motor, and can be widely applied to the three-dimensional carving of Shoushan stone, Tianhuang stone and other jade, such as pendant, jade plaque, Buddha image, inkstone and other handicraft production.

[0003] In the carving of a long strip-shaped Shoushan stone, the strip-shaped Shoushan stone usually needs to be clamped and fixed, and then a vertically arranged carving tool is used for rotary carving. The carving precision of the Shoushan stone is related to the carving tool and the carving program, and is also related to the stability of the clamping of the jade.

[0004] In the existing Shoushan stone carving device, when the long strip-shaped Shoushan stone is clamped during the carving process, a clamping jaw is usually used to directly clamp one end of the strip-shaped Shoushan stone. The Shoushan stone is brittle, and the general clamping jaw is easy to clamp and damage the Shoushan stone due to excessive clamping force, causing cracks or even direct collapse of the Shoushan stone. If the clamping force is too small, the Shoushan stone may be clamped loosely during the carving process, which affects the carving quality of the Shoushan stone. In particular, when the long strip-shaped Shoushan stone is rigidly clamped, the surface of the Shoushan stone is more likely to be damaged, thereby causing the whole Shoushan stone to be scrapped. In addition, the strip-shaped Shoushan stone is bonded to the clamping part by using a thermosetting glue. However, this clamping method is easy to cause the center line of the strip-shaped Shoushan stone to be skewed, and it takes a long time to bond the Shoushan stone, which needs to be bonded carefully by manual operation, and the efficiency is extremely low. Secondly, the existing carving tool usually starts to carve the strip-shaped Shoushan stone from the end that is not clamped to the clamped end. After a period of carving, the already carved part is exposed. At this time, the carving tool rotates at high speed and touches the Shoushan stone, causing the flying of the broken stone. The hard broken stone can cause secondary damage to the already carved part of the Shoushan stone, thereby causing carving defects. Therefore, in view of the above problems, it is urgent to develop a Shoushan stone carving device to overcome the above problems of the existing carving device. SUMMARY
