Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a clamping mechanism for a tungsten alloy roller grinding machine. Background Technology

[0002] A roller grinding mill is a type of equipment used for material processing. It primarily uses rotating rollers and embedded balls to crush and grind various raw materials to obtain ultrafine powder of a target mesh size. Although the rollers and balls in this equipment are usually made of tungsten alloy with extremely high hardness, they will still experience varying degrees of wear with repeated use. If left unattended, this will affect the grinding accuracy in subsequent processing, resulting in substandard finished products. To ensure processing accuracy, these parts must be replaced promptly. Furthermore, the grinding mill must be cleaned when processing different types of materials. These processes are usually performed manually, which is time-consuming, labor-intensive, and potentially dangerous. An auxiliary device is needed to address these issues. Utility Model Content

The clamping assemblies clamp the housing of the grinding machine, and a carrier plate is connected between the two lifting cylinders on the tail side of the base plate. A grinding cylinder corresponding to the grinding machine is provided on the carrier plate, and a cooling assembly is connected to the grinding cylinder body.

[0004] Furthermore, the drive assembly includes a drive motor, which is mounted on a connecting beam on one side.

The top of the output end of the lifting cylinder 2 on the same side is connected to a bearing beam 3. A movable beam 4 is slidably connected between the two bearing beams 3. The movable beam 4 is connected to a drive assembly. The drive assembly includes a drive motor 8, which is mounted on a connecting beam 9 on one side. The two connecting beams 9 are respectively connected to the ends of the two bearing beams 3. A spiral rod 801 at the output end of the drive motor 8 is rotatably connected to the connecting beam 9 on the opposite side. The spiral rod 801 is threadedly connected to the movable beam 4. Several clamping components are provided on the bottom surface of the movable beam 4. The clamping components include a clamping seat 10. The top surface of the clamping seat 10 is rotatably connected to the bottom surface of the movable beam 4. The bottom ends of the two clamping arms of the clamping seat 10 are threadedly connected to an adjusting rod 11. The outer end of the adjusting rod 11 is connected to a turntable 12. The inner end of the adjusting rod 11 is rotatably connected to a gripper 13. The inner arc surface of the gripper 13 cooperates with the housing 5 of the grinding machine and is provided with a soft pad.

[0018] In this embodiment, the grinding machine includes a grinding motor 16, which is mounted on the top of the housing 5. The output end of the grinding motor 16 is vertically connected to a roller 17. The roller 17 is surrounded by a plurality of balls 18. After the roller 17 is inserted into the grinding cylinder 7, each ball 18 contacts the inner wall of the grinding cylinder 7. The outer ring of the opening on the bottom surface of the housing 5 is matched with the sealing ring on the top surface of the grinding cylinder 7. A filling port 501 is provided on one side of the housing 5. The grinding cylinder 7 is mounted on the carrier plate 6, which is mounted between the two lifting cylinders 2 on the tail side of the base plate 1. The grinding cylinder 7 is connected to a cooling assembly, which includes a cold water tank 14. The cold water tank 14 is surrounded by several heat sinks. The bottom output end of the cold water tank 14 is connected to a circulation pump 15. The output end of the circulation pump 15 is connected to the inlet of the water jacket 701 inside the grinding cylinder 7. The outlet of the water jacket 701 is connected to the upper input end of the cold water tank 14. The top surface of the cold water tank 14 is provided with a material holding trough 1401, which is located directly below the discharge port 702 of the grinding cylinder 7.

[0019] The working principle of this utility model is as follows:

[0020] When the grinding machine needs to be operated for grinding, the housing 5 is connected to the grinding cylinder 7, the roller 17 is inserted into the grinding cylinder 7, the raw material is fed into the grinding machine from the feeding port 501, the grinding motor 16 is started, the high-speed rotating roller 17 drives the ball bearing 18 to crush and grind the raw material, and the ground raw material particles fall into the holding tank 1401 through the discharge port 702. During this process, the circulating pump 15 is started to draw the coolant in the cold water tank 14 into the water jacket 701 for cooling. The water jackets are connected by vertical channel columns. After the cooling water flows several times in the cylinder wall of the grinding cylinder 7, it is discharged from the bottom water jacket 701 into the cold water tank 14.

[0021] When it is necessary to replace or clean the parts of the grinder, start the lifting cylinder 2 to raise the grinder, and then start the drive motor 8 to move the grinder directly above the grating plate 19. The grinder can be sprayed or replaced here. The wastewater generated by spraying passes through the grating plate 19 and falls into the drainage trough 20. During this process, the grinder can be rotated 360 degrees in the clamped state, or the turntable 12 can be rotated to remove the grinder.

[0022] This invention uses a clamping component to fix the grinder, and with the cooperation of the lifting cylinder 2 and the drive component, it can realize the rapid lifting and horizontal movement of the grinder, which greatly facilitates the disassembly, assembly and cleaning process of the machine and improves the maintenance and use efficiency of the grinder.
