[0002] A milling cutter is a commonly used tool on numerically controlled machine tools. It performs metal cutting by rotating and is used for fine milling. Multiple cutters are installed on the milling cutter, and each cutter can work. Its rotation speed and forward speed can be adjusted according to the requirements of the workpiece to be processed.

[0003] During the use of the milling cutter, the staff needs to frequently add oil to it. Frequent refueling results in low convenience of use. In the prior art, bolts are used to fixedly install the blades on the cutter. There are many blades on the cutter, so the number of bolts is large. And the time required to operate each bolt is long, resulting in troublesome installation of the blades. Summary of the Invention

The top of the cutter head is fixedly connected with an oil tank through a plurality of cushion blocks. The bottom wall of the oil tank is provided with a plurality of connection grooves arranged in an array. The inside of each connection groove is slidably connected with a lifting frame. The bottom ends of the lifting frames all slide through the cutter head and are fixedly connected with circular blocks. The top ends of the lifting frames are fixedly connected with lifting plates at positions corresponding to the inside of the oil tank. At positions corresponding to the lifting plates inside the oil tank, extrusion frames are fixedly connected. At positions corresponding to the extrusion frames inside the oil tank, first springs are fixedly connected. Through grooves are symmetrically arranged on each lifting frame. Baffles are slidably connected inside the through grooves. Pressure-bearing blocks are fixedly connected to the outer walls of the baffles. Support seats are fixedly connected inside each lifting frame. Symmetrically arranged second springs are fixedly connected to the support seats. Leakage grooves are symmetrically arranged on the cutter head at positions corresponding to the lifting frames; A plurality of sliding grooves are arranged in an array on the cutter head. Moving rings are slidably connected inside the sliding grooves. Moving blocks are fixedly connected to the moving rings at positions corresponding to the sliding grooves. Third springs are fixedly connected to the outer walls of the moving blocks. Two clamping rods are fixedly connected to the cutter head at positions adjacent to the sliding grooves. Blades are jointly slidably connected to the top and bottom clamping rods. Limiting grooves are provided on the blades at positions corresponding to the moving rings.

[0006] Specifically, the specific shape of the extrusion frame is C-shaped. The bottom ends of the extrusion frames all penetrate through the lifting plates and are located inside the lifting frames at the top ends of the lifting frames.

[0007] Specifically, the extrusion frames are located at the hollow position of the first spring, the bottom ends of the extrusion frames are in contact with the corresponding pressure blocks, and the bottom ends of the first springs are fixedly connected with the corresponding lifting plates.

[0008] Specifically, a guide rod is fixedly connected to the hollow position of the second spring on the support seat, one end of the guide rod slides through the corresponding baffle plate, and the second spring is fixedly connected to the corresponding baffle plate.

[0011] Specifically, the top of the moving block is fixedly connected with a pushing block, and one end of the moving ring slides through the outer wall of the cutter disc and the limiting groove.

[0012] The beneficial effects of the present invention are as follows: when installing the blade, the present invention only needs to connect the blade and the clamping rod in advance, and then move the moving ring so that the moving ring is connected to the blade to complete the fixing of the blade, and when the cutter disc is performing cutting work, the linkage of various components will cause the blocking plate to move toward the middle direction of the lifting frame, and at this time, the oil inside the oil tank will be vibrated by the vibration force when the cutter disc is running. At this time, the oil inside the oil tank will flow onto the cutter disc, and then slowly flow from the top of the cutter disc to the bottom of the cutter disc, the outflowing oil can lubricate the cutter disc, and can also absorb the temperature of the cutter disc rotating and cutting, so as to achieve the effect of cooling and lubricating the cutter disc. The present invention can reduce the frequency of staff refueling the cutter disc, improve the convenience of using the cutter disc, and also facilitate the installation and disassembly of the blade on the cutter disc, and has high convenience of use.

Specific embodiments

[0016] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] As Figures 1-8 shown, a milling cutter head with a self-cooling function and a lubricating structure disclosed by the present invention includes a cutter head 1. The top end of the cutter head 1 is fixedly connected with a fuel tank 2 through a plurality of cushion blocks. A plurality of connecting grooves 3 arranged in an array are opened on the bottom wall of the fuel tank 2. Lifting frames 4 are slidably connected inside the connecting grooves 3. The bottom ends of the lifting frames 4 all slidably penetrate through the cutter head 1 and are fixedly connected with circular blocks 5. Lifting plates 6 are fixedly connected to the top ends of the lifting frames 4 corresponding to the positions inside the fuel tank 2. Extrusion frames 7 are fixedly connected to the fuel tank 2 corresponding to the positions of the lifting plates 6. First springs 8 are fixedly connected to the fuel tank 2 corresponding to the positions of the extrusion frames 7. Symmetrically arranged through grooves 9 are opened on the lifting frames 4. Baffles 10 are slidably connected inside the through grooves 9. Bearing blocks 11 are fixedly connected to the outer walls of the baffles 10. Support seats 12 are fixedly connected inside the lifting frames 4. Second springs 13 arranged symmetrically are fixedly connected to the support seats 12. Leakage grooves 14 arranged symmetrically are opened on the cutter head 1 corresponding to the positions of the lifting frames 4; A plurality of sliding grooves 15 arranged in an array are opened on the cutter head 1. Moving rings 16 are slidably connected inside the sliding grooves 15. Moving blocks 17 are fixedly connected to the moving rings 16 corresponding to the positions of the sliding grooves 15. Third springs 18 are fixedly connected to the outer walls of the moving blocks 17. Two clamping rods 19 are fixedly connected to the cutter head 1 adjacent to the sliding grooves 15. Blades 20 are jointly slidably connected to the top and bottom clamping rods 19. Limiting grooves 21 are opened on the blades 20 corresponding to the positions of the moving rings 16.

[0018] The specific shape of the extrusion frame 7 is set in a C shape. The bottom ends of the extrusion frames 7 all penetrate through the lifting plate 6 and are located inside the top end of the lifting frame 4 within the lifting frame 4. The extrusion frames 7 are all located at the hollow position of the first spring 8. The bottom ends of the extrusion frames 7 are all in contact with the corresponding pressure-bearing blocks 11. The bottom ends of the first springs 8 are all fixedly connected to the corresponding lifting plates 6. When the pressure-bearing blocks 11 move upward, the bottom ends of the extrusion frames 7 will extrude the obliquely arranged outer walls of the pressure-bearing blocks 11. The pressure-bearing blocks 11 that are subjected to extrusion will all move towards the middle direction inside the lifting frame 4. The pressure-bearing blocks 11 will all drive the baffle plates 10 to move together. At this time, the baffle plates 10 move away from the through grooves 9, and the through grooves 9 are in an open state. Guide rods 22 are fixedly connected to the support seats 12 at the hollow positions corresponding to the second springs 13. One ends of the guide rods 22 all slide through the corresponding baffle plates 10. The second springs 13 are all fixedly connected to the corresponding baffle plates 10. The guide rods 22 facilitate guiding the movement of the baffle plates 10, while the second springs 13 facilitate driving the baffle plates 10 to reset. The specific shape of the fuel tank 2 is set in a circular ring shape. An oil inlet 23 is fixedly connected to the top end of the fuel tank 2. The oil inlet 23 communicates with the fuel tank 2. The oil inlet 23 facilitates the staff to add oil into the fuel tank 2. The specific shapes of the sliding grooves 15 are all set in an arc shape. The third springs 18 are all fixedly connected to the inner walls of the sliding grooves 15. The third springs 18 facilitate driving the moving blocks 17 and the moving rings 16 to reset. Push blocks 24 are fixedly connected to the top ends of the moving blocks 17. One ends of the moving rings 16 all slide through the outer wall of the cutter head 1 and the limiting grooves 21. The push blocks 24 facilitate the staff to push the moving blocks 17. The connection between the moving rings 16 and the limiting grooves 21 facilitates fixing the positions of the blades 20.

[0019] During use, when the cutter head 1 rotates to cut a certain object, the circular block 5 will first come into contact with the top of the object. At this time, when the cutter head 1 continues to descend, the extrusion force will cause the circular block 5 to move upward. When the circular block 5 moves upward a certain distance, the blade 20 on the cutter head 1 will abut against the object to be cut. At this time, the rotation of the cutter head 1 driving the blade 20 will cut the object to be cut normally. The circular block 5 that is extruded and moved upward will drive the lifting frame 4 and the lifting plate 6 to move upward together. The upward movement of the lifting plate 6 will compress and contract the first spring 8. The upward movement of the lifting frame 4 will drive the baffle 10 and the bearing block 11 to move upward. The upward movement of the bearing block 11 will be passively extruded by the extrusion frame 7. At this time, as the baffle 10 and the bearing block 11 move upward, the bearing block 11 will move toward the middle position inside the lifting frame 4 during the upward movement. The bearing block 11 will also drive the baffle 10 to move. The guide rod 22 guides the movement of the baffle 10. At the same time, when the baffle 10 moves toward the middle, it will compress and contract the second spring 13. At this time, the moving baffle 10 will be separated from the through groove 9. And at this time, the vibration force of the rotating cutter head 1 will act on the oil inside the fuel tank 2. Just when the through groove 9 is in an open state, the oil inside the fuel tank 2 will flow downward through the through groove 9 to the top of the cutter head 1, and then the flowing oil will flow to the bottom of the cutter head 1 and the object to be cut through the leakage groove 14 on the cutter head 1. At this time, the blade 20 following the rotation of the cutter head 1 will be in full contact with the flowing oil, which can improve the lubrication degree of the rotation of the cutter head 1 and the blade 20, and can also absorb the heat generated by the rotation and cutting of the blade 20. When the blade 20 needs to be disassembled, just push the moving block 17 through the pushing block 24. The moving block 17 will drive the moving ring 16 to move inside the sliding groove 15. At the same time, the moving block 17 will compress and contract the third spring 18. And the moving moving ring 16 will retract into the sliding groove 15. The movement of the moving ring 16 will be separated from the limiting groove 21. At this time, the blade 20 can be directly pulled off the two clamping rods 19 to complete the disassembly of the blade 20. The disassembly of the remaining blades 20 is the same reason, and the operation is very convenient, which can reduce the time required for the disassembly and installation of the blade 20. In addition, the oil inside the fuel tank 2 can be used by the cutter head 1 for a period of time, and can achieve the effect of self-lubrication when the cutter head 1 is working.
