[0018] Embodiment

[0019] As Figure 1 - Figure 2 shown, the present utility model provides a grinding head,

[0020] It includes a housing 1, a grinding head main shaft 2, a pulley 3, and a grinding wheel 4. The grinding head main shaft 2 passes through the housing 1 and extends to both sides of the housing 1 at its left and right ends respectively. The pulley 3 and the grinding wheel 4 are respectively arranged at both ends of the grinding head main shaft 2. A tool - mounting connection block 5 is arranged on the housing 1. A first positioning hole 6 is provided on the tool - mounting connection block 5, and a second positioning hole 7 matching the first positioning hole 6 is provided on the housing 1. The tool - mounting connection block 5 and the housing 1 are fixedly connected by bolts through the first positioning hole 6 and the second positioning hole 7. The housing 1 is connected to a lathe through the tool - mounting connection block 5. The motor drives the pulley 3 to rotate, thereby driving the grinding head main shaft 2 to rotate, and then driving the grinding wheel 4 to perform grinding operations. A grinding wheel rear baffle 8 is arranged on the grinding head main shaft 2. The grinding wheel rear baffle 8 is located at the rear side of the grinding wheel 4, and a grinding wheel fixing rod 9 is connected between the grinding wheel rear baffle 8 and the grinding wheel 4;

[0021] Cover plates 10 are arranged on both the left and right sides of the housing 1, and the grinding head main shaft 2 passes through the cover plates 10.

[0022] A bearing adjusting sleeve 11 is arranged on the grinding head main shaft 2. The bearing adjusting sleeve 11 can be used to adjust the clearance of the bearing, ensuring the flexibility and stability of the bearing during operation. By adjusting the bearing clearance, the friction and wear of the bearing can be reduced, and the service life of the bearing can be improved. The bearing adjusting sleeve 11 can finely adjust the position of the bearing, thereby affecting the rotation accuracy of the grinding head main shaft 2.

[0023] The first positioning holes 6 are provided in several groups, and the several groups of first positioning holes 6 are evenly spaced. The first positioning holes 6 and the second positioning holes 7 are arranged in one - to - one correspondence.

[0024] A positioning groove is provided on the side wall of the end of the cover plate 10 facing the housing 1, and a positioning protrusion is provided on the surface of the end of the housing 1 facing the cover plate 10. The cover plate 10 and the housing 1 are fixedly connected by plugging through the positioning groove and the positioning protrusion.

[0025] This application drives the pulley 3 through a motor, thereby driving the grinding head main shaft 2 to rotate. The grinding wheel 4 on the main shaft rotates at a high speed to perform grinding operations. The housing 1 is connected to a lathe through the tool - mounting connection block 5, ensuring the stability of the grinding head and the accuracy of the operation. The design of the grinding wheel rear baffle 8 and the grinding wheel fixing rod 9 ensures the stable installation of the grinding wheel 4, preventing it from shifting or falling off during high - speed rotation, thereby improving the safety and precision of the operation.

[0026] This application includes the following steps during use:

[0027] Installation and connection:

[0028] Connect the grinding head to the lathe through the tool mounting block 5. The first positioning hole 6 on the tool mounting block 5 is fixedly connected to the second positioning hole 7 on the housing 1 by bolts to ensure that the grinding head is stably mounted on the lathe.

[0029] Drive and transmission:

[0030] Start the motor. The motor drives the grinding head spindle 2 to rotate through the pulley 3. The design of the pulley 3 makes the transmission smoother and more efficient.

[0031] Rotation of the grinding wheel 4 and grinding:

[0032] As the grinding head spindle 2 rotates, the grinding wheel 4 mounted on the spindle also starts to rotate at high speed. Bring the workpiece to be ground close to the rotating grinding wheel 4 for grinding operations. The high-speed rotation and frictional action of the grinding wheel 4 can remove the uneven parts on the surface of the workpiece and make it smooth.

[0033] Safety and stability:

[0034] The grinding wheel rear baffle 8 and the grinding wheel fixing rod 9 work together to ensure the stability and safety of the grinding wheel 4 during high-speed rotation. The rear baffle prevents the grinding wheel 4 from moving backward or falling off during operation, while the fixing rod keeps the grinding wheel 4 balanced and in a fixed position.

[0035] Maintenance and debugging:

[0036] During use, the grinding head spindle 2 can be finely adjusted through the bearing adjusting sleeve 11 to ensure the precision and effect of grinding. When it is necessary to replace or repair the grinding wheel 4, it can be easily disassembled and installed, improving the convenience of maintenance.

[0037] In summary, the grinding head of this application realizes stable and precise grinding operations through a simple and efficient design, while ensuring the safety and ease of operation.

[0038] The grinding head design of this application simplifies the overall structure through a reasonable structural layout, making the assembly process more convenient. The tool mounting block 5 and the housing 1 are fixedly connected through positioning holes and bolts. This connection method is both firm and easy to disassemble, greatly improving the efficiency of assembly and disassembly.

[0039] The setting of the bearing adjusting sleeve 11 enables the clearance and position of the grinding head spindle 2 to be finely adjusted. This flexibility not only helps to reduce the wear of the bearings but also plays an important role in improving the machining accuracy. Through fine adjustment, it can be ensured that the grinding wheel 4 maintains a stable trajectory during high-speed rotation, thereby improving the precision and quality of the grinding operation.

[0040] Through the design of the grinding wheel rear baffle 8 and the grinding wheel fixing rod 9, the fixing of the grinding wheel 4 is more stable, effectively preventing the grinding wheel 4 from shifting or falling off during high-speed operation. This not only enhances the safety of the operation but also ensures the continuity and stability of the grinding operation.

[0041] In the design of the grinding head of this application, full consideration has been given to the safety of operation and the reliability of the equipment. Through reasonable structural layout and firm connection methods, the stability and safety of the equipment during high-speed operation are ensured, reducing the operation risk.
