Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, and specifically to a grinding wheel correction device applied to a cylindrical grinding machine. Background Technology

[0002] Cylindrical grinding machines are specifically designed for grinding cylindrical, conical, or other rotationally symmetrical external surfaces. With the increasing number of high-precision, high-hardness mechanical parts and the development of precision casting and precision forging processes, the performance of cylindrical grinding machines is constantly improving, the variety of models is constantly increasing, and the output is also constantly growing to meet the growing precision machining needs of various industries.

[0003] Traditional grinding wheel installation methods, such as directly placing the grinding wheel between the upper and lower clamps and clamping it onto the drive shaft, are difficult to accurately position due to the assembly gap between the outer circle of the clamps and the inner hole of the grinding wheel. This can easily lead to eccentricity, requiring long-term manual adjustment, making it difficult to guarantee accuracy. Consequently, this affects the machining accuracy of the workpiece and also shortens the service life of the grinding wheel. Utility Model Content

Positioning posts 615 are located inside the pressure ring 613, and the positioning posts 615 are evenly distributed about the axis of the pressure ring 613. The detachable component 63 includes a baffle 631. A boss 632 is slidably connected to the outer surface of the baffle 631. A buffer ring 633 is fixedly connected to the outer surface of the boss 632. A shaft groove 635 and a column hole 634 are opened on the outer surface of the boss 632.

The baffle 631 and the cover 611 form a semi-enclosed structure. Placing the working component 62 in the middle can make the whole mechanism more compact.

[0031] Example 3, as Figures 1 to 8 As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the transmission component 64 includes a transmission shaft 641, and a key 642 is fixedly connected to the outer surface of the transmission shaft 641. The key 642 allows for a tighter connection between the transmission shaft 641 and the working component 62. One end of the transmission shaft 641 near the cover 611 passes through the pad 612 and is fixed to the interior of the tailstock 5. The outer surface of the transmission shaft 641 is fixed to the inner wall of the pad 612. The transmission shaft 641 not only transmits power but also connects various components.

[0032] The working principle of this grinding wheel straightening device applied to an external cylindrical grinding machine is described in detail below:

[0033] During use, the elastic deformation of the compression spring ring 614 and the buffer ring 633 reduces the gap generated during the installation of the grinding wheel 621. The pressure ring 613 and the boss 632 can fix the grinding wheel 621 between the cover 611 and the baffle 631. The positioning post 615 can significantly reduce the time required for installation and alignment, and also reduce eccentricity, ensuring machining accuracy. When the baffle 631 compresses the grinding wheel 621, the pad 616 at the top of the positioning post 615 is embedded in the post hole 634. The pad 616 is deformed to a certain extent by the compression of the positioning post 615 and the inner wall of the post hole 634, which can make the positional relationship between the protective component 61 and the detachable component 63 closer, and also make the fixing of the grinding wheel 621 more reliable. The protruding key 642 on the drive shaft 641 can prevent the grinding wheel 621 from slipping during rotation, which would affect the surface accuracy of the workpiece.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
