[0029] A circular processing opening 5 is provided at the front end of the device plate 1 located in the front and at the corresponding position of each cutting head 2. The diameter of the processing opening 5 is the same as that of the cylinder to be processed. The cylinder is passed through the processing opening 5 so that its end is against the corresponding cutting head 2 to perform the chamfering cutting work. A waste plate is fixedly connected to the lower position of the opposite side of the front end of the two device plates 1. The setting of the waste plate is convenient for collecting waste chips generated during processing, and the setting of the two device plates 1 can effectively prevent waste chips from flying around.

[0030] A top plate 6 is fixedly connected to the upper front end of the device plate 1 located in the front, and a bottom plate 7 is fixedly connected to the lower front end. A lifting plate 8 is fitted on the front end of the device plate 1 located in the front. An arc-shaped placement groove 9 is provided on the upper end of the lifting plate 8 and at the position of each processing port 5. The arc of the placement groove 9 is the same as that of the processing port 5, which facilitates the stable placement of the cylinder. The left and right ends of the lifting plate 8 are fixedly connected to the lifting sleeve blocks 10, and the two lifting sleeve blocks 10 are vertically penetrated and threadedly connected with threaded rods 11. The upper and lower ends of the two threaded rods 11 are rotatably connected to the top plate 6 and the bottom plate 7 respectively. A double-headed motor 12 is fixedly installed on the upper end of the bottom plate 7. The two output ends of the double-headed motor 12 are coaxially fixedly connected with transmission rods 13. The two transmission rods 13 extend to the positions of the two threaded rods 11 at one end away from the double-headed motor 12 respectively. The two transmission rods 13 are connected to the corresponding threaded rods 11 through a second bevel gear pair 14. The double-headed motor 12 can drive the two transmission rods 13 to rotate synchronously at the same time. Then, under the transmission action of the second bevel gear pair 14, the two threaded rods 11 can rotate at the same speed, thereby simultaneously driving the vertical movement of the two lifting sleeve blocks 10 to achieve the lifting and lowering of the lifting plate 8.

[0031] A material box 15 is fixedly connected to the upper end of the top plate 6, and the material box 15 is used to load the cylinder barrels of the hydraulic cylinder to be processed. The cylinder barrels in the material box 15 are all placed longitudinally, and the longitudinal length of the front and rear inner walls of the material box 15 is equal to the longitudinal length of a cylinder barrel. A cylinder outlet box 16 connected to the lower end of the material box 15 is fixedly connected to the lower end of the top plate 6 and at the corresponding position of the placement groove 9. An electric gate 17 is provided at the lower opening of each cylinder outlet box 16. Two cylinder barrels are provided in each cylinder outlet box 16. The horizontal length of the cylinder outlet box 16 is equal to the diameter of a cylinder barrel, the vertical length of the cylinder outlet box 16 is equal to the diameter of two cylinder barrels, and the longitudinal length of the cylinder outlet box 16 is equal to the longitudinal length of a cylinder barrel. Each cylinder outlet box 16 can only keep the state of storing two cylinder barrels.

[0032] Two movable rods 18 arranged at intervals in front and back are horizontally penetrated and slidably connected on the left and right sides of each tube box 16 and at the two common positions. The two movable rods 18 corresponding to the front and rear are fixedly connected to a limit block 19 at one end located in the tube box 16, and fixedly connected to a fixed plate 20 at one end away from the tube box 16. Two springs 21 are fixedly connected between the fixed plate 20 and the outer wall of the tube box 16. The two springs 21 are respectively sleeved on the corresponding movable rods 18. The end of each fixed plate 20 away from the tube box 16 is fixedly connected to a cylindrical block 22. In the absence of external force, each limit block 19 is embedded in the inner wall of the tube box 16. Vertical push plates 23 are fixedly connected to the upper end of the lifting plate 8 and at both sides of each tube box 16. The upper ends of each vertical push plates 23 are inclined toward the side away from the corresponding tube box 16.

[0033] Specifically, the double-headed motor 12 drives the lifting plate 8 to move upward so that it moves close to the discharge box 16. When the lifting plate 8 moves to a certain distance from the lower end of the discharge box 16, each electric gate 17 opens, and the lowest cylinder in the discharge box 16 falls onto the lifting plate 8 and is stably placed in the corresponding placement groove 9. The position of another cylinder in the discharge box 16 remains unchanged. When the lifting plate 8 moves upward, the upper end of each vertical push plate 23 first contacts the corresponding cylindrical block 22, and pushes the movable rod 18 into the corresponding discharge box 16, so that the two limit blocks 19 in the discharge box 16 are stuck between the two cylinders, which play a limiting role. Then, when the cylinder located at the bottom falls, the position of the cylinder located at the top remains unchanged. After the lifting plate 8 completes the material receiving, the double-headed motor 12 drives it to move downward, and the electric gate 17 is closed accordingly. After the vertical push plate 23 moves out of the position of the cylindrical block 22, each limit block 19 is also reset under the action of the spring 21, and the cylinders in the cylinder box 16 can be automatically replenished to two, waiting for the next material discharge. There is no need to manually place the cylinders, saving time and effort.

[0034] The front end of the bottom plate 7 is fixedly connected to the front baffle 24, and the front end of the front baffle 24 is fixedly installed with a telescopic cylinder 25. The telescopic end of the telescopic cylinder 25 passes through the front baffle 24 and is fixedly connected to a push cylinder plate 26. The end of the push cylinder plate 26 away from the front baffle 24 is fixedly connected to an arc plate 27 corresponding to each processing port 5. The rear end of the push cylinder plate 26 and the inner wall of the arc plate 27 are fixedly embedded with rubber pads 28. When the lifting plate 8 with the cylinder barrel is placed is moved to the position of the processing port 5, the telescopic cylinder 25 can drive the cylinder box 26 to push each cylinder barrel to move backward, so that the rear end thereof passes through the processing port 5 and abuts against the corresponding cutting head 2. Under the action of the rubber pad 6 of the push cylinder plate 26, each cylinder barrel cannot rotate, so that stable rounded corner cutting can be performed. After the cutting is completed, the telescopic cylinder 25 contracts, and the arc plate 27 and the rubber pad 28 attached to the upper end of each cylinder barrel are used to pull the processed cylinder barrel out of the placement groove 9 for collection, and then the placement of the cylinder barrel to be processed can continue. The working mode is automatic and continuous, which greatly improves the processing efficiency.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
