[0036] Please refer to Figures 1 to 4 , Figure 1 is a schematic diagram of the five-axis knife grinder 100 in an embodiment of the utility model embodiment; Figure 2 is Figure 1 the side view of the five-axis knife grinder 100 of Figure 3 is Figure 1 the enlarged schematic diagram of the partial structure of the five-axis knife grinder 100 of Figure 4 is Figure 1 the partial structure schematic diagram of the five-axis knife grinder 100 of the utility model embodiment provides a kind of five-axis knife grinder 100, five-axis knife grinder 100 including base 10, cutting device 20, balancing assembly 30 and manipulator 40.Cutting device 20 includes cutting mechanism 21 and lifting assembly 22, lifting assembly 22 is installed on base 10, and is connected with cutting mechanism 21, lifting assembly 22 can drive cutting mechanism 21 to lift relative to base 10.Balancing assembly 30 is installed on base 10, and is connected with lifting assembly 22, balancing assembly 30 provides driving force to lifting assembly 22 to balance the vertical load of lifting assembly 22.Manipulator 40 is installed on lifting assembly 22, and is used to transfer the workpiece 1000 to be processed to the bottom side of cutting mechanism 21.

[0037] Specifically, the cutting mechanism 21 may include a grinding wheel 211 and a driver for driving the grinding wheel 211 to work. The grinding wheel 211 is used to grind the workpiece 1000. The lifting assembly 22 includes a vertical slider 221 and a vertical linear motor 222. The vertical slider 221 is slidably connected to the base 10 in the vertical direction. The stator of the vertical linear motor 222 is mounted on the base 10, and the mover of the vertical linear motor 222 is connected to the vertical slider 221. The cutting mechanism 21 is mounted on the vertical slider 221. The balancing assembly 30 is connected to the vertical slider 221, and the robot arm 40 is mounted on the vertical slider 221.

[0038] Understandably, the cutting mechanism 21 is used to process the workpiece 1000. The vertical linear motor 222 can drive the vertical slider 221 to move the cutting mechanism 21 in the vertical direction. The balancing component 30 can generate a force on the vertical slider 221 in the vertical upward direction, thereby reducing the load when the vertical linear motor 222 drives the vertical slider 221. The robot arm 40 and the cutting mechanism 21 are both mounted on the vertical slider 221, which enables the robot arm 40 and the cutting mechanism 21 to move synchronously. This makes it convenient for the robot arm 40 to transfer the workpiece 1000 to the bottom side of the cutting mechanism 21, and makes the robot arm 40 flexible in loading.

[0039] In this embodiment of the five-axis grinding machine 100, on the one hand, the robot arm 40 and the cutting mechanism 21 are both mounted on the lifting assembly 22, so that the robot arm 40 can move synchronously with the cutting mechanism 21, thereby making the robot arm 40 flexible in loading materials.

[0042] It can be understood that the gas pressure of the nitrogen gas 1011 acts on the liquid level of the hydraulic oil 1012, can press the hydraulic oil 1012 from the hydraulic pipe 1016 into the cylinder body 311 of the hydraulic cylinder 31, and generate a thrust on the piston rod 312 of the hydraulic cylinder 31, so that the hydraulic cylinder 31 can generate an external force, and the pressure regulator 1013 can change the gas pressure of the nitrogen gas 1011 in the oil reservoir 32 by filling or discharging the nitrogen gas 1011 into the oil reservoir 32, so as to change the thrust of the hydraulic oil 1012 on the piston rod 312 after entering the cylinder body 311, thereby adjusting the driving force of the hydraulic cylinder 31 to adapt to the vertical load of the lifting assembly 22 under different conditions.

[0049] Specifically, the top center 91 is connected with the adjusting assembly 92 in a clamped manner. It should be understood that the top center 91 can also be connected with the adjusting assembly 92 in a manner of welding, gluing, magnetic attraction, etc. The top center mechanism 90 further comprises an adjusting seat 94 and a bearing driver 95. The adjusting seat 94 is slidably connected with the base 10 in a horizontal direction.

The screw can also abut against the adjusting block 921 to realize relative fixation of the position of the adjusting assembly 92, thereby realizing adjustment of the horizontal angle of the top center 91 in cooperation with the adjusting assembly 92, so as to help the top center 91 to abut against the workpiece 1000 concentrically and improve the machining precision of the workpiece 1000. The bearing driver 95 drives the adjusting seat 94 to move, so that the top center 91 can approach or move away from the workpiece 1000, thereby facilitating abutment and disassembly of the workpiece 1000.
