Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel grinding machines, in particular to a grinding wheel grinding machine with an auxiliary cooling mechanism. Background Art

[0002] Grinding machines are primarily used for precision machining of machine parts, and are particularly well-suited for batch grinding of high-precision gears. The machining principle is form grinding, where the cross-section of the grinding wheel shaft is trimmed to correspond to the gear tooth groove, and then form grinding is performed.

[0003] Due to the intense friction, the temperature of the grinding zone is very high, which will cause stress and deformation of the workpiece, and even cause burns on the workpiece surface. Therefore, a large amount of coolant must be injected during grinding to reduce the grinding temperature. The coolant can also play a role in chip removal and lubrication. In the existing technology, the coolant is generally recycled when used, but the temperature of the recycled coolant is still high. Directly using it for cooling will greatly reduce the cooling effect, and it will not have a cooling effect on the grinding area, which is insufficient in practicality. Therefore, it is necessary to redesign a grinding wheel grinding machine with an auxiliary cooling mechanism to address the above problems. Utility Model Content

Frame 18, a second screw 19 is rotatably installed inside the moving frame 18, a second motor 20 connected to the second screw 19 is fixedly installed on the outer wall of the moving frame 18, and a moving sleeve 22 is threadedly installed on the outer wall of the second screw 19 through a second limiting mechanism. The second limiting mechanism includes a second limiting rod 21 fixedly installed inside the moving frame 18, and the second limiting rod 21 slides through the moving sleeve 22. The second limiting rod 21 can limit the moving sleeve 22 so that the moving sleeve 22 can only move axially along the outer wall of the second screw 19.

[0026] The upper end of the movable sleeve 22 is fixedly connected to the connecting frame 24 via a connecting mechanism.

Then, the circulating pump 15 can pump the coolant that has been re-cooled in the recovery box 5, and pump it out to the inside of the nozzle 26 through the cooperation of the connecting pipe 16 and the telescopic hose 27. The coolant is then sprayed from the inside of the nozzle 26 to cool the outer wall of the workpiece, thereby avoiding deformation of the workpiece due to high temperature.
