Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding head angle adjustment mechanism for a grinding machine. Background Technology

[0002] Grinding machines are machine tools that use abrasive wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines.

[0003] Grinding machines in the current technology usually achieve vertical and horizontal movement through two guide rails. However, the shape of some products requires grinding from multiple angles. Such grinding machines can only be used by changing different grinding heads, which is inconvenient during processing. Utility Model Content

[0004] To address the problem that existing grinding machines typically use two guide rails to achieve movement in both the vertical and horizontal directions, but some product shapes require grinding from multiple angles, and such grinding machines can only be used by changing the grinding head, which is inconvenient during processing, this application provides a grinding head angle adjustment mechanism.

[0005] A grinding head angle adjustment mechanism for a grinding machine includes a guide rail base, a column mounted on the guide rail base, the column being slidably connected to the guide rail base, the column moving up and down along the guide rail base, a spindle mounted on the column, the spindle being rotatably connected to the column, a feed seat at the end of the spindle, a feed frame slidably mounted on the feed seat, the feed frame sliding along the length direction of the grinding head, and the feed frame being used to mount the grinding head.

[0006] By adopting the above technical solutions, the grinding head angle adjustment mechanism of the grinding machine achieves flexible adjustment of the grinding head in space. The sliding connection between the column and the guide rail allows the column to move up and down along the guide rail, thereby adjusting the height of the grinding head; the rotational connection between the spindle and the column, as well as the sliding arrangement between the feed seat and the feed frame, allow the grinding head to be precisely positioned in the horizontal direction and can also be adjusted in angle by rotation, improving the adaptability and accuracy of grinding processes.

[0007] Optionally, an angle adjustment motor is provided on the column corresponding to the main shaft, and the rotating shaft of the angle adjustment motor is fixedly connected to the main shaft.

[0008] By adopting the above technical solution, an angle adjustment motor is installed on the column, and the motor's shaft is fixedly connected to the spindle, thereby realizing the spindle's angle adjustment function. This design allows the grinding head to flexibly adjust its angle during processing, adapting to the processing requirements of different workpiece surfaces and improving processing accuracy and efficiency.

[0009] Optionally, a height adjustment motor is provided on the guide rail base, and a height adjustment screw is fixedly provided on the rotating shaft of the height adjustment motor. The height adjustment screw is threadedly connected to the column, and the column can move up and down along the guide rail base when the height adjustment screw rotates.

[0010] By adopting the above technical solution, the height adjustment motor drives the height adjustment screw to rotate, which can precisely control the vertical movement of the column on the guide rail, thereby achieving accurate vertical positioning of the grinding head. This design not only improves the automation level of grinding head adjustment but also effectively reduces errors caused by manual operation, ensuring the consistency and stability of grinding processes.

[0011] Optionally, a feed motor is provided on the feed seat, and a feed screw is fixedly provided on the rotating shaft of the feed motor. The feed screw is threadedly connected to the feed frame, and the feed frame slides along the length direction of the feed seat when the feed screw rotates.

[0012] By adopting the above technical solution, the feed motor drives the feed screw to rotate, and the feed screw is threadedly connected to the feed holder, thereby enabling the feed holder to slide precisely along the length direction of the feed seat. This solution allows for more precise adjustment of the grinding head's position in the feed direction, improving the positioning accuracy of grinding. Combined with the column height adjustment function and the spindle angle adjustment function, the overall solution enables multi-degree-of-freedom adjustment of the grinding head in space, meeting the grinding requirements of different workpieces and improving the adaptability and processing efficiency of the grinding machine.

[0013] Optionally, the feed seat is provided with guide rails corresponding to the feed frame, the guide rails are respectively provided on both sides of the feed frame, and the feed frame abuts against the guide rails.

[0014] By adopting the above technical solutions, the guide rails effectively limit the movement direction of the feed carriage, ensuring its smooth sliding along the length of the feed seat and preventing the feed carriage from deviating or tilting during movement. The guide rails are respectively located on both sides of the feed carriage and abut against it, further improving the stability and accuracy of the feed carriage's movement, thereby enhancing the quality and efficiency of the grinding head's processing.

[0015] Optionally, both ends of the main shaft are provided with rotating bearings, the rotating bearings are fixedly connected to the column, and the main shaft is rotatably connected to the column by means of the rotating bearings.

[0016] By adopting the above technical solution, rotating bearings are installed at both ends of the spindle, and the rotating bearings are fixedly connected to the column, enabling the spindle to rotate with the column. This design effectively reduces the frictional resistance between the spindle and the column, improves the smoothness of spindle rotation, and extends the service life of both the spindle and the column.

[0017] Optionally, a mounting bracket is provided at the position of the spindle corresponding to the feed frame, and the feed frame is fixedly connected to the mounting bracket.

[0018] By adopting the above technical solutions, the spindle and feed carriage are fixedly connected through a mounting bracket, thereby improving the installation stability of the feed carriage on the spindle and effectively avoiding loosening or misalignment problems that may occur due to direct connection. Combined with the technical means of connecting the spindle to the column via a rotating bearing, the precise positioning and angle adjustment capabilities of the grinding head during operation are further ensured, improving the overall machining accuracy and reliability of the grinding machine.

[0019] Optionally, a planar thrust bearing is provided between the mounting bracket and the column, and an oil seal is provided on the outer side of the planar thrust bearing.

[0020] By adopting the above technical solution, a planar thrust bearing is installed between the mounting frame and the column, which effectively reduces the frictional resistance during spindle rotation, improves transmission efficiency, reduces wear, and extends the service life of the equipment. An oil seal is installed on the outside of the planar thrust bearing to prevent lubricating oil leakage and to prevent external impurities from entering, ensuring normal bearing operation and further enhancing the stability and reliability of the overall structure.

[0021] In summary, this application has at least the following beneficial effects:

[0022] This application addresses the problem that existing grinding machines typically use two guide rails to achieve movement in both the vertical and horizontal directions. However, some product shapes require grinding from multiple angles, and such grinding machines can only perform grinding by changing the grinding head, which is inconvenient during processing. This application solves the problem by setting a spindle that can drive the grinding head to adjust the angle, allowing the grinding head to rotate and adjust the angle during operation, eliminating the need to change the grinding head and improving the convenience of processing.
