Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, and more specifically, to a guiding mechanism for a centerless grinder. Background Technique

[0002] When grinding a workpiece on a centerless grinder, it is not necessary to position the axis of the workpiece. It mainly consists of three mechanisms: a grinding wheel, a workpiece support, and an adjusting wheel. It has the advantages of continuous processing, no need to retract the tool, short copying time for clamping the workpiece, and high productivity. When processing a workpiece on a centerless grinder, a guiding mechanism is required to limit the workpiece so that the workpiece can stably enter between the grinding wheel and the adjusting wheel, thereby grinding the workpiece.

[0003] The patent document with the publication number CN218837058U in the prior art provides a guiding mechanism for a centerless grinder. The device includes a base. A fixed seat is fixedly connected to the left side of the upper part of the base. A limiting block is fixedly connected to the upper part of the fixed seat. A workpiece support is fixedly connected to the right side of the fixed seat. A movable seat is arranged on the right side of the upper part of the base. A limiting block is fixedly connected to the upper part of the movable seat. A chute is arranged on the right side of the upper part of the base. A threaded rod is rotatably connected to the right side inside the base. A movable block is threadedly connected to the outer periphery of the threaded rod. The lower part of the movable seat is fixedly connected to the upper part of the movable block. A hand wheel is fixedly connected to the right end of the threaded rod, which can avoid the reduction of the accuracy of the guiding mechanism. At the same time, the guiding mechanism for the centerless grinder can guide irregular workpieces and prevent the workpieces from getting stuck inside the guiding mechanism.

[0004] Although the device has many beneficial effects, there are still the following problems: During the use of the device, it can only guide workpieces of the same length and cannot adjust the guiding length. Moreover, it can only guide and feed grinders of the same height and cannot adjust the guiding height, so it needs to be improved. In view of this, we propose a guiding mechanism for a centerless grinder. Content of the Utility Model
