The piston rod of the first cylinder 14 is fixedly connected to one end of the fixing pin 15. The size of the fixing pin 15 is adapted to the size of the positioning hole 17.

[0027] In one embodiment, the outer sidewall of the rotating motor 10 is fixedly connected to the top of the bottom plate 40, the output end of the rotating motor 10 is fixedly connected to the bottom of the turntable 11, one end of the connecting rod 12 is fixedly connected to the top of the turntable 11, the bottom of the processing plate 13 is fixedly connected to the other end of the connecting rod 12, the installation groove 16 is opened at the top of the processing plate 13, and the first cylinder 14 drives the fixing pin 15 to insert into the positioning hole 17, so that the fixing pin 15 fixes the processing plate 13, thereby avoiding shaking during the grooving process, ensuring the stability of the device, and improving the grooving accuracy. When grooving both ends of the camshaft, first groove one end of the camshaft. After one end of the camshaft is grooved, control the first cylinder 14 to drive the fixing pin 15 to move out of the positioning hole 17, so that the fixing pin 15 releases the fixation of the processing plate 13. At this time, control the rotating motor 10 to drive the turntable 11 to rotate 180 degrees, so that the turntable 11 drives the processing plate 13 to rotate 180 degrees, and aligns the other end of the camshaft with the grooving assembly 301, thereby completing the grooving operation on both ends of the camshaft. This device can groove both ends of the camshaft without disassembling the camshaft, improving work efficiency.

[0028] In one embodiment, the fixing assembly 201 includes a second cylinder 20, a first fixing clamp plate 21 and a second fixing clamp plate 22. The outer sidewall of the second cylinder 20 is fixedly connected to one side of the processing plate 13, the piston rod of the second cylinder 20 is fixedly connected to one side of the first fixing clamp plate 21, and the bottom of the second fixing clamp plate 22 is fixedly connected to one side of the processing plate 13. Place the camshaft between the first fixing clamp plate 21 and the second fixing clamp plate 22, and drive the first fixing clamp plate 21 to move through the second cylinder 20, so that the first fixing clamp plate 21 and the second fixing clamp plate 22 fix the camshaft, avoiding the camshaft from falling off, and thus ensuring safety during grooving.

[0029] In one embodiment, the grooving assembly 301 includes a plate body 30, a grooving machine 31 and a milling cutter 32; the bottom of the plate body 30 is fixedly connected to the bottom of the bottom plate 40, the outer sidewall of the grooving machine 31 is installed on one side of the plate body 30, and the outer sidewall of the milling cutter 32 is installed at the output end of the grooving machine 31. Through the setting of the plate body 30, it plays a role in fixing the grooving machine 31. Through the setting of the grooving machine 31 and the milling cutter 32, this device can groove the end face of the camshaft.

[0030] When the utility model is working: First, the staff places the camshaft in the installation groove 16, and then controls the second cylinder 20 to drive the first fixed clamping plate 21 to move, so that the first fixed clamping plate 21 and the second fixed clamping plate 22 fix the camshaft, avoiding the camshaft from falling off, thus ensuring the safety during grooving. Then, control the grooving machine 31 to perform grooving operations on one end of the camshaft. When grooving is required at both ends of the camshaft, first perform grooving operations on one end of the camshaft, and then control the first cylinder 14 to drive the fixing pin 15 to move out of the positioning hole 17, so that the fixing pin 15 releases the fixation on the processing plate 13. At this time, control the rotating motor 10 to drive the turntable 11 to rotate 180 degrees, so that the turntable 11 drives the processing plate 13 to rotate 180 degrees, aligning the other end of the camshaft with the grooving assembly 301. Then, control the first cylinder 14 to drive the fixing pin 15 to insert into the positioning hole 17, so that the fixing pin 15 plays a role in fixing the processing plate 13, avoiding shaking during the grooving process, ensuring the stability of the device, improving the grooving accuracy. Then, control the grooving machine 31 to perform grooving on the other end of the camshaft, thus completing the grooving operations on both ends of the camshaft. After the grooving of both ends of the camshaft is completed, control the second cylinder 20 to drive the first fixed clamping plate 21 to retract, and the camshaft can be taken out from the processing plate 13, enabling the device to groove both ends of the camshaft without disassembling the camshaft, improving the work efficiency.
