[0032] At present, if the cutting resistance increases due to tool wear or stone itself problems during the cutting process of the jade cutting machine, the cutting program will continue to execute, thereby causing the driving motor to be overloaded, causing the motor to be damaged, and also increasing the jade scrap rate. In order to solve the above technical problems, the present application proposes the following technical solutions:

[0034] The sensing assembly 433 is a disc structure, and a plurality of connecting holes corresponding to the bolt 423 are arranged on the sensing assembly 433, during installation, the bolt 423 penetrates the bolt holes of the upper shaft coupling body 421 and the connecting holes of the sensing assembly 433 in sequence, and finally penetrates out through the bolt hole of the lower shaft coupling body 422, and locks and fixes the upper and lower ends of the bolt 423.

[0035] The diameter of the driven shaft 431 is smaller than the diameter of the transmission screw rod 43, so that a limiting step is formed between the top of the transmission screw rod 43 and the bottom of the driven shaft 431, for fixing the spiral spring 410.

[0036] In the normal state, the position of the induction assembly 433 is below the detection component 10, when the tool wear or stone problem causes large resistance during cutting, the driving screw 43 moves up to drive the driven shaft 431 to move up synchronously, so that the driven shaft 431 drives the induction assembly 433 at the top to move up to the same height as the detection component 10, and the detection component 10 is electrically connected with the first motor 41, thereby judging that the cutting encounters large resistance, and the first motor 41 is stopped working through the electrical signal control, thereby avoiding the first motor 41 from being damaged due to overload.

[0037] Therefore, during the cutting process, the jade blank is placed on the clamping assembly to be fixed, and then the cutting device 5 and the first motor 41 are started, so that the first motor 41 drives the driving screw 43 to rotate through the shaft coupling 42, the driving screw 43 is connected with the lifting transmission block 46 in the right side mounting plate 47 of the cutting device 5 through the internal thread and the external thread, and the sliding blocks 49 on both sides cooperate with the guide rails 48, thereby driving the cutting device 5 to move downward, so as to complete the cutting of the jade;

[0038] When the cutting device 5 cannot continue to cut downward due to tool wear or uneven hardness of the stone during the cutting process, the first motor 41 continues to rotate to drive the lifting transmission block 46 to continue to move downward along the driving screw 43, the resistance generated during cutting makes the cutting device 5 unable to continue to move downward, the first motor 41 continues to drive the driving screw 43 to rotate, and the cutting device 5, the mounting plate 47 and the lifting transmission block 46 cannot move downward due to the resistance, thereby driving the driving screw 43 to move upward, so that the sliding plate 432 at the bottom of the driving screw 43 moves upward along the sliding groove 451, the driven shaft 431 at the top of the driving screw 43 moves upward synchronously, thereby pressing the spiral spring 410, and the induction assembly 433 at the top of the driven shaft 431 moves upward synchronously and is at the same level with the detection component 10, after the detection component 10 detects the induction assembly 433, the first motor 41 is stopped working through the electrical signal control, thereby avoiding the first motor 41 from being damaged due to overload caused by too large cutting resistance, and avoiding the jade from being cut into defective products due to too large resistance, improving the safety of the equipment and reducing the defective rate of the jade.

[0039] When the resistance disappears, the spiral spring 410 expands and pushes the driving screw 43 to move downward to reset, the induction assembly 433 moves downward with the driven shaft 431, and the detection component 10 cannot detect the induction assembly 433, the first motor 41 continues to work through the electrical signal control.

[0040] The right side of the stand 3 is provided with an electric control box 6 electrically connected with the lifting mechanism 4 and the cutting device 5, and the front of the stand 3 is provided with a control panel 7, which improves the convenience of operation of the equipment, enhances the intelligent control of the system, and ensures the efficiency and safety of the cutting process.

[0046] Among them, the top of the second proximity switch 93 is below the upper surface of the placement table 92, avoiding collision of the cutting tool with the second proximity switch 93.

[0047] When cutting the jade outer ring, place the jade on the workbench 92, and drive the pressure plate 95 along the guide column 94 to move downward by driving the cylinder 97, so as to tightly fix the jade, and then drive the cutting device 5 to move downward by the lifting mechanism 4 to cut, until the jade is completely cut through, the second proximity switch 93 detects the cutting tool, and then the first motor 41 and the cutting device 5 stop working through electrical signal control, so that even if the tool is worn and the cutting edge depth is shortened, the equipment can still ensure that the jade is completely cut through, without stopping for turning or adjustment, avoiding unnecessary interruption, effectively improving the yield of jade, reducing the waste rate, and significantly improving the overall cutting efficiency.
