Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a mechanical arc workpiece grinder. Background Art

[0002] Grinding is the grinding process of a workpiece with a grinding wheel or other abrasive tools, and its main motion is the rotation of the grinding wheel. The grinding process of the grinding wheel is actually the combined effect of the three actions of abrasive particles on the surface of the workpiece, namely cutting, carving and sliding. In the field of mechanical workpiece processing, most of the grinding processes are for workpieces of regular shapes. The processing surfaces of these workpieces are mostly regular planes, either the bottom or top surface, or the side surface. The grinding of these planes is mostly performed by grinders. However, for some irregular workpieces, such as arc-shaped workpieces, arc-shaped workpieces generally have many burrs on the outer circumference of the workpiece after rough processing. At this time, the burrs need to be ground to meet the use requirements.

[0003] For example, the patent document with application number 202122417268.3 discloses a mechanical arc workpiece grinder. The utility model belongs to the field of mechanical processing technology and relates to a mechanical arc workpiece grinder, which includes a working box, a base is provided inside the working box, a connecting cavity is opened inside the base, a collecting box is movable inside the connecting cavity, the top of the collecting box is an open design, a collecting groove is opened on the top of the base, and the collecting groove is communicated with the connecting cavity. The beneficial effect is that the mechanical arc workpiece grinder, through the arrangement of the first drive motor, the first threaded rod, the sliding seat, the third drive motor, the third threaded rod, etc., realizes that when the grinder is grinding the arc-shaped parts, the first drive motor drives the sliding plate and the sliding seat to move through the first threaded rod, and the third drive motor drives the push plate and the moving seat to move through the third threaded rod, so that the grinding wheel uniformly grinds the surface of the arc-shaped parts, thereby increasing the grinding effect of the grinder. However, the mechanical arc workpiece grinder cannot be adjusted to a suitable angle when grinding workpieces of different arc sizes, and requires repeated grinding many times, which greatly reduces the grinding efficiency.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a mechanical arc workpiece grinding machine is proposed. Utility Model Content
