[0022] like Figure 1-8 As shown, one end of one group of clamping seats 504 is rotatably connected to a three-jaw chuck 7, and the other group of clamping seats 504 is rotatably connected to a circular ring seat 8. The three-jaw chuck 7 can clamp and fix the front end of the crankshaft of the crankshaft body, and the circular ring seat 8 supports the rear end of the crankshaft of the crankshaft body, and then the clamping seats 504 move toward each other to clamp and fix the crankshaft body.

[0023] like Figure 1-8 As shown, the limiting mechanism 6 includes an arc plate 601 movably arranged at the front and rear ends of the top of the processing table 1, and an arc seat 602 is connected to the opposite side of the two groups of arc plates 601. Movable connecting arc plates 603 are installed at both ends of the arc seat 602. The arc seat 602 can move toward the crankshaft body during the downward movement of the blade assembly 407, so that the two groups of connecting arcs move toward each other to protect the outer side of the crankshaft body. The waste chips generated during the cutting process will only adhere to the inner side of the connecting arc plate 603 and the arc seat 602, reducing the splash range of the waste chips.

[0024] like Figure 1-8As shown, arc grooves 9 are provided at both ends of the arc seat 602, and springs 10 are arranged at equal angles inside the arc grooves 9.

The spring 10 allows the connecting arc plate 603 to move toward the inner side of the arc seat 602, thereby adjusting the extension length of the connecting arc plate 603 and providing limit protection for crankshaft bodies of different lengths.

[0025] like Figure 1-8 As shown, a groove 11 is provided at the front and rear ends of the inner side of the support plate 2, an oil tank 12 is connected to the bottom of the groove 11, a connecting groove 13 is provided at one end of the bottom of the oil tank 12, an oil block 14 connected to the oil tank 12 is fixed inside the connecting groove 13, a movable plate 15 is movably connected inside the oil block 14, a fixed plate 16 fixed at the bottom of the arc plate 601 is connected to the opposite sides of the two groups of movable plates 15, a long plate 17 is connected to the center of the front and rear ends of the guide shaft 402, a vertical plate 18 extending into the oil tank 12 is connected to the bottom of the long plate 17, and in the process of the hydraulic rod 401 controlling the guide shaft 402 to move downward, the long plate 17 will be driven to push the vertical plate 18 downward to squeeze the oil, so that the movable plate 15 moves toward the direction of the crankshaft body, pushes the fixed plate 16 and then pushes the arc plate 601, so that the arc plate 601 is driven to move toward the direction of the crankshaft body simultaneously during the downward movement of the blade assembly 407, and the protection effect on the outer side of the crankshaft body is automatically achieved.

[0026] like Figure 1-8 As shown, the tops of the two groups of connecting arc plates 603 can be spliced ​​with a long through hole structure, and the bottoms of the two groups of connecting arc plates 603 can be spliced ​​with a short through hole structure. A collection box 19 is installed at the top center of the processing table 1. The tops of the two groups of connecting arc plates 603 can be spliced ​​with a long through hole structure so that the blade assembly 407 can move left and right to cut the connecting rods at different positions. During the cutting process, the spray coolant in the prior art is used for cooling. During the cooling process of the coolant spray, the liquid will wash away the waste chips remaining on the outer wall of the crankshaft body and the inner side of the connecting arc plate 603 and the arc seat 602, and finally flow down from the short through hole structure to be collected by the collection box 19.

[0027] Working principle: When in use, one end of the crankshaft body to be processed is clamped in the center of the three-jaw chuck for fixation, and the other end is supported on the inner side of the circular ring seat. Then, the hydraulic rod 401 is set to control the guide shaft 402 to move up and down, so that the distance of the blade assembly 407 toward the connecting rod of the crankshaft body can be controlled, so as to control the cutting outer diameter of the connecting rod, and the driving device is set to control the rotation of the threaded rod 404 and then control the threaded seat 405 to move left and right, so that the connecting plate 406 drives the blade assembly 407 to move left and right to cut the connecting rods at different positions. In the process of the hydraulic rod 401 controlling the guide shaft 402 to move downward, it will drive the long plate 17 to push the vertical plate 18 downward to squeeze the oil, so that the movable plate 15 moves toward the direction of the crankshaft body, pushes the fixed plate 16 and then pushes the arc plate 601, so that the arc plate 601 is driven to move toward the direction of the crankshaft body in the process of the blade assembly 407 moving downward, and the protection effect of the outer side of the crankshaft body is automatically achieved. Then, the bidirectional screw 50 is controlled by the driving device. The rotation can drive the two groups of connecting seats 503 to move toward or away from each other so as to clamp the crankshaft bodies of different lengths, and the connecting arc plate 603 can be squeezed during the movement of the clamping seat 504, so that the length of the connecting arc plate 603 can be automatically adjusted according to the length of the crankshaft body. The arc seat 602 can move toward the crankshaft body during the downward movement of the blade assembly 407, so that the two groups of connecting arcs move toward each other to protect the outer side of the crankshaft body. The waste chips generated during the cutting process will only adhere to the inner side of the connecting arc plate 603 and the arc seat 602, reducing the splash range of the waste chips. The tops of the two groups of connecting arc plates 603 can be spliced ​​with a long through hole structure so that the blade assembly 407 can move left and right to cut the connecting rods at different positions. During the cutting process, the spray coolant in the prior art is used for cooling. During the cooling process of the coolant spray, the liquid will wash the waste chips remaining on the outer wall of the crankshaft body and the inner side of the connecting arc plate 603 and the arc seat 602, and finally flow down from the short through hole structure to be collected by the collection box 19.
