Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a mechanical clamping tool. Background Art
[0002] Mechanical clamping is one of the commonly used clamping methods in the manufacturing industry. It uses a clamp to fix the workpiece. In mechanical clamping, there are two sources of clamping force: one is self-gravity, that is, the weight of the workpiece itself gives the clamp a force, and the other is the lever principle, that is, after the clamp is acted upon by an external force, a reverse supporting force is generated on the clamping surface.
[0003] In the prior art, Chinese patent publication number CN212265188U discloses a mechanical clamping tool for bench processing, including a base, a fixed ring is fixed to the upper end of the base through a support rod, a first turntable is threadedly connected to the outer ring on one side of the fixed ring, and a second turntable is connected to the side wall of the other side of the fixed ring through a bearing, the axes of the fixed ring and the second turntable are arranged on the same axis, the fixed ring and the second turntable are axially provided with a through hole, and the axes of the fixed ring and the second turntable are horizontally interspersed with rods, and the outer wall of the fixed ring is arrayed with a plurality of slide grooves with the axis of the fixed ring as the midpoint, and the slide groove and the through hole of the fixed ring are connected through a first circular hole, the opening direction of the first circular hole is the radial direction of the fixed ring, and a square block is arranged in the slide groove. A mechanical clamping tool for bench processing can adjust the cutting length through the second turntable in the clamped state, without loosening the rod, is simple to use, and is suitable for cutting rods of different outer diameters, and the cutting length of the rod is easy to control.
[0004] During use, the mechanical clamping tooling used for bench processing only relies on the first turntable, the bearing, and the second turntable to clamp and fix the workpiece. In the process of fixing the workpiece, the worker needs to use both hands to clamp and fix the workpiece. This method of fixing the workpiece by human power can easily cause the fixed workpiece to loosen during the subsequent processing, thereby affecting the processing efficiency of the workpiece, resulting in poor use of this equipment, and therefore needs to be improved.
