[0018] Specifically, the transmission mechanism 211 is a relatively mature component in the prior art application, and is composed of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate under the action of the transmission belt.

[0019] Starting the second motor 207 can drive the connecting shaft 210 to rotate through the transmission mechanism 211, thereby driving the cutting disc 208 to rotate.

[0020] like Figure 1-Figure 7 As shown, a first motor 201 is provided inside the workbench 1, and the output shaft of the first motor 201 is fixedly connected to a screw rod 202, the other end of the screw rod 202 is rotatably connected to the inner wall of the storage groove 102, and the surface of the screw rod 202 is threadedly connected to a connecting seat 203, both sides of the connecting seat 203 are slidably connected to the inner wall of the storage groove 102, and a mounting block 204 is provided on the top of the connecting seat 203, and the top of the mounting block 204 is fixedly connected to the bottom of the mounting shell 209.

[0021] A counterweight rod 205 is fixedly connected to the bottom of the mounting block 204, and the lower end of the counterweight rod 205 passes through the connecting seat 203 and is slidably connected to the inner wall of the connecting seat 203. A mounting rod 206 is provided on the inner wall of the storage groove 102. Both ends of the mounting rod 206 pass through the workbench 1 and are fixedly connected to a fixed block 214. The mounting block 204 is slidably connected to the surface of the mounting rod 206.

[0022] Two liquid storage cylinders 216 are fixedly connected on both sides of the workbench 1, and the inner wall of one of the liquid storage cylinders 216 is slidably connected to a first adjusting rod 218, and the bottom of the first adjusting rod 218 and the inner wall of the liquid storage cylinder 216 are filled with hydraulic oil.

[0023] Two symmetrically distributed cavities 212 are formed inside the installation shell 209 , and evenly distributed exhaust holes 213 communicating with the cavities 212 are formed on the top of the installation shell 209 .

[0024] By starting the first motor 201, the screw rod 202 can be driven to rotate, and in the process, the connecting seat 203 is driven to slide along the inner wall of the storage groove 102, so that the mounting block 204 is driven by the counterweight rod 205 to make the mounting shell 209 move synchronously, thereby achieving the effect of driving the cutting disc 208 to move. Under normal circumstances, the counterweight rod 205 can keep the cutting disc 208 inside the storage groove 102 under the action of gravity, and the auxiliary mechanism 3 is driven downward by the hydraulic push rod 215 to drive the first adjustment rod 218 to move downward, so that it can squeeze the liquid stored in the storage cylinder 2 The hydraulic oil inside 16 is injected into another liquid storage cylinder 216 through the conduit 217 and lifts the second adjusting rod 219, so that the second adjusting rod 219 drives the fixing block 214 to move upward, thereby driving the mounting rod 206 through the fixing block 214 to move the mounting block 204 upward, and the cutting disc 208 can be extended from the inside of the storage groove 102. When it is not fixed, the gravity of the counterweight rod 205 ensures that the cutting disc 208 will not extend from the inside of the storage groove 102 when the metal plate to be cut is not fixed, thereby improving the safety factor.

[0025] like Figure 1-Figure 7 As shown, the auxiliary mechanism 3 includes a connecting shell 301 arranged on the top of the workbench 1, and both sides of the connecting shell 301 are fixedly connected with mounting parts fixedly connected to the output shaft of the hydraulic push rod 215, and the inner side of the connecting shell 301 is fixedly connected with two symmetrically distributed mounting boxes, and ventilation grooves 302 are opened on the opposite sides of the two mounting boxes. The inner wall of the mounting box is fixedly connected with a filter 303, and the interior of the mounting box is provided with a fan 304 located on the side of the filter 303 away from the ventilation groove 302.

[0026] The surface of the installation box is connected with an air guide tube 305 , and the other end of the air guide tube 305 is connected with the cavity 212 .

[0027] Both sides of the connecting shell 301 are fixedly connected with a fixing plate 306, a pressing plate 309 is arranged at the bottom of the fixing plate 306, and the top of the pressing plate 309 is fixedly connected with evenly distributed positioning rods 307, the upper ends of the positioning rods 307 pass through the fixing plate 306, and a spring 308 is sleeved on the surface of the positioning rods 307.

[0028] The output shaft of the hydraulic push rod 215 is contracted to drive the connecting shell 301 to move downward. In this process, the metal sheet placed on the workbench 1 can be squeezed and fixed by the joint action of the fixing plate 306, the pressing plate 309, the positioning rod 307 and the spring 308, thereby reducing shaking during the cutting process and improving the cutting effect. Moreover, the positioning rod 307 and the spring 308 cooperate with each other to enable the positioning rod 307 to pass through the fixing plate 306 and compress the spring 308 after the pressing plate 309 contacts the metal sheet and is blocked by the metal sheet. After being compressed, the spring 308 applies a reaction force to the pressing plate 309 to improve the limiting effect on the metal sheet, thereby avoiding the damage of the metal sheet caused by excessive squeezing. Starting the fan 304 during the cutting process can guide the airflow through the ventilation slot 302 into the interior of the installation box, so that it can guide the debris generated during the cutting process into the interior of the installation box. During this process, the filter 303 can filter the debris, and the filtered airflow is introduced into the interior of the cavity 212 through the air guide tube 305 and discharged through the exhaust hole 213. This can speed up the air flow around the cutting disk 208 during the cutting process, reduce the impact of high temperature generated during the cutting process, effectively increase the service life of the equipment, and reduce the thermal damage of the metal plate caused by high temperature.

[0029] Working principle: The metal sheet to be cut is placed on the workbench 1 and located below the connecting shell 301. The output shaft of the hydraulic push rod 215 is contracted to drive the connecting shell 301 to move downward. In this process, the metal sheet placed on the workbench 1 can be squeezed and fixed by the joint action of the fixing plate 306, the pressing plate 309, the positioning rod 307 and the spring 308, thereby reducing the shaking during the cutting process and improving the cutting effect. In addition, as the connecting shell 301 moves downward, the first adjusting rod 218 can be driven downward to squeeze the metal sheet stored in the liquid storage. The hydraulic oil inside the cylinder 216 is injected into another liquid storage cylinder 216 through the conduit 217 and lifts the second adjusting rod 219, so that the second adjusting rod 219 drives the fixed block 214 to move upward, thereby driving the mounting rod 206 through the fixed block 214 to move the mounting block 204 upward, thereby achieving the effect of extending the cutting disc 208 from the inside of the storage groove 102. When it is not fixed, the gravity of the counterweight rod 205 ensures that the cutting disc 208 will not extend from the inside of the storage groove 102 when the metal plate to be cut is not fixed, thereby improving the safety factor.
