Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device for a spiral milling cutter, belonging to the technical field of grinding devices. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. During operation, each tooth cuts off the excess of the workpiece in turn and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. Spiral milling cutters are a type of milling cutter with spiral teeth. During the milling process, the surface and the edge of the cutting edge need to be polished.

[0003] The patent document with the prior art publication number CN218658097U provides a grinding device for a spiral milling cutter, including a pedestal, one end of which is fixed with a fixed seat, a grinding wheel is rotatably mounted on the fixed seat, and the fixed seat is connected to a motor belt mechanism for driving the grinding wheel to rotate. A support rod is horizontally slidably mounted on the other end of the pedestal, and a movable rod is rotatably connected to the upper end of the support rod, and a mounting sleeve with an open end is fixed to the end of the movable rod. The movable rod of the utility model cooperates with a support block and a locking screw to enable the mounting sleeve to horizontally support the spiral milling cutter to move right and contact the grinding wheel for end grinding, thereby preventing the spiral milling cutter from tilting. When the spiral milling cutter moves to the left for a short distance, the mounting sleeve can be rotated to tilt upward, so that the right end of the spiral milling cutter is away from the grinding wheel for convenient extraction of the mounting sleeve, thereby grinding by moving the spiral milling cutter to the right and rotating it counterclockwise after moving it to the left to take it out, thereby assisting the operator to manually complete the end grinding of the spiral milling cutter.

[0004] However, the existing grinding device for spiral milling cutters has poor flexibility. During the use of the grinding device, when the grinding device grinds the spiral milling cutter, since the spiral part of the spiral milling cutter is the blade, and the blade of the spiral milling cutter is most easily damaged during the processing, when it is damaged and needs to be polished, the staff needs to manually adjust the spiral milling cutter and rotate the spiral milling cutter to polish the spiral milling cutter. However, manual operation has low precision and is prone to excessive grinding or uneven grinding of the blade during the grinding process. For this reason, we propose a grinding device for the spiral milling cutter. Utility Model Content
