[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A fillet rolling machine for machining automotive crankshafts includes a base 1, a main control unit 11 fixedly connected to the surface of the base 1, the main control unit 11 having a built-in PLC controller and a touch screen interface, a support plate 12 fixedly connected to the surface of the base 1, and a rolling roller feed device 13 fixedly mounted on the surface of the base 1. The rolling roller feed device 13 is equipped with a closed-loop feedback system to monitor rolling pressure and position changes in real time and has overload protection. Under the control of the rolling roller feed device 13, the rolling roller body 14 precisely rolls the fillet area of ​​the crankshaft according to a predetermined trajectory. This is existing technology. The rolling roller body 14 is set on the surface of the rolling roller feed device 13. A first servo motor 2 is fixedly connected to the surface of the main control unit 11. A rotating rod 21 is fixedly connected to the output shaft of the first servo motor 2. The end of the first servo motor 2 away from the main control unit 11 is rotatably connected to the surface of the support plate 12. The rotating rod 21 is mounted on the surface of the main control unit 11. A first support rod 22 is fixedly connected, a second support rod 23 is fixedly connected to the surface of the rotating rod 21, a second servo motor 24 is fixedly connected to the surface of the first support rod 22, a first hydraulic chuck 25 is fixedly connected to the output shaft of the second servo motor 24, and a second hydraulic chuck 26 is rotatably connected to the surface of the second support rod 23. The first hydraulic chuck 25 and the second hydraulic chuck 26 cooperate to install and fix the automobile crankshaft. The first hydraulic chuck 25 and the second hydraulic chuck 26 are existing technologies, usually using a four-jaw hydraulic self-centering chuck. The hydraulic system pushes the inclined slider mechanism inside the chuck, causing the jaws to move synchronously towards the center, thereby clamping the journals at both ends of the crankshaft. After the automobile crankshaft is processed, the other set of first hydraulic chucks 25 and second hydraulic chucks 26 can be installed and fixed, and the automobile crankshaft can be directly lifted to the processing position for processing, avoiding the time wasted during installation and disassembly, thus greatly improving the processing efficiency.

[0024] Furthermore, a cleaning mechanism is provided on the surface of the roller feed device 13. The cleaning mechanism includes a support platform 3, which is fixedly connected to the surface of the roller feed device 13. A movable frame 31 is rotatably connected to the surface of the support platform 3. A vacuum cleaner 32 is fixedly connected to the surface of the movable frame 31. The vacuum cleaner 32 provides negative pressure suction to remove metal debris generated during the rolling process. A connecting rod 33 is fixedly connected to the surface of the movable frame 31. An electric push rod 34 is rotatably connected to the surface of the roller feed device 13. The piston rod of the electric push rod 34 is rotatably connected to the bottom of the connecting rod 33. This cleaning mechanism can move the vacuum cleaner 32 to the front of the automobile crankshaft machining to clean up the debris generated during the automobile crankshaft machining in a timely manner, thereby ensuring the precision of automobile crankshaft machining.

[0025] Furthermore, two sets of the second servo motor 24 and the first hydraulic chuck 25 are provided on the first support rod 22, and two sets of the second hydraulic chuck 26 rotate on the second support rod 23. The two sets of first hydraulic chuck 25 and second hydraulic chuck 26 correspond to each other, thereby enabling the replacement of the automobile crankshaft machining. The first servo motor 2 drives the rotating rod 21 to rotate on the support plate 12 through the output shaft. The first servo motor 2 has a built-in locking mechanism, which can lock the position of the first servo motor 2 after rotation, preventing the first servo motor 2 from rotating again, thereby ensuring the stability of automobile crankshaft machining.

[0026] Furthermore, the first support rod 22 and the second support rod 23 are parallel to each other, and the first support rod 22 and the second support rod 23 remain perpendicular after rotation. The rotating rod 21 drives the first hydraulic chuck 25 and the second hydraulic chuck 26 to rotate synchronously through the first support rod 22 and the second support rod 23. The first hydraulic chuck 25 and the second hydraulic chuck 26 drive the automobile crankshaft to rotate, thereby changing the position of the automobile crankshaft. The automobile crankshaft located at the higher position is in the processing area, while the automobile crankshaft located at the lower position can be installed and disassembled, avoiding affecting the processing efficiency of the automobile crankshaft.

[0027] Furthermore, the second servo motor 24 drives the first hydraulic chuck 25 to rotate on the first support rod 22 via the output shaft. The first hydraulic chuck 25 drives the automobile crankshaft to rotate, while the other end of the automobile crankshaft rotates on the second hydraulic chuck 26. The automobile crankshaft is processed by rotating and engaging with the rolling roller body 14.

[0028] Furthermore, the movable frame 31 is L-shaped. The movable frame 31 drives the vacuum cleaner 32 to rotate on one side of the roller feed device 13. The movable frame 31 can rotate the vacuum cleaner 32 to the front of the automobile crankshaft, thereby ensuring the cleaning effect of the debris during the processing of the automobile crankshaft.

[0029] Furthermore, the movable frame 31 is provided in two sets, and the connecting rod 33 connects the two sets of movable frames 31 at the same time. The electric push rod 34 drives the connecting rod 33 and the movable frame 31 to rotate on the support platform 3 through the piston rod, thereby changing the position of the vacuum cleaner 32 on the roller feed device 13, avoiding the vacuum cleaner 32 from affecting the switching of the car crankshaft, and enabling the vacuum cleaner 32 to more effectively clean the debris of the car crankshaft.

[0030] Working principle: The two sets of first hydraulic chucks 25 and second hydraulic chucks 26 are respectively equipped with automobile crankshafts. After one set of automobile crankshafts is processed, the output shaft of the first servo motor 2 drives the rotating rod 21 to rotate. The rotating rod 21 drives the first support rod 22 and the second support rod 23 to rotate. The second support rod 23 drives the two sets of first hydraulic chucks 25 and second hydraulic chucks 26 to switch positions, thereby switching the positions of the two sets of automobile crankshafts. At this time, the unprocessed automobile crankshaft enters the processing area, while the processed automobile crankshaft enters the unprocessed area, thereby saving the time of automobile crankshaft installation and removal and improving the processing efficiency of automobile crankshafts.

[0031] A large amount of debris is generated during the machining of the automobile crankshaft. The movable frame 31 rotates on top of the roller feed device 13 via the support platform 3, while the electric push rod 34 drives the connecting rod 33 and the movable frame 31 to rotate on top of the roller feed device 13 via the piston rod. The movable frame 31 rotates the vacuum cleaner 32 to the front of the automobile crankshaft machining, so that the vacuum cleaner 32 can clean the debris of the automobile crankshaft. The debris affects the machining of the automobile crankshaft, thus ensuring the machining accuracy of the automobile crankshaft.
