Description

Technical Field

[0001] The invention relates to the technical field of knife sharpening equipment, and in particular to a loading and unloading mechanical clamping device for knife sharpening equipment. Background Art

[0002] The existing loading and unloading mechanical clamps realize automatic loading and unloading clamping, mainly including a standard pneumatic finger cylinder with an inner diameter of 16mm and a long clamping claw arm, so that the pneumatic finger cylinder drives the two long clamping claw arms to close together to clamp the cylindrical workpiece at the same time. However, the reliability of the traditional loading and unloading clamps is not high in actual use, and the service life is short. Whether it is domestic or imported finger cylinders, it is difficult to use for a long time in a harsh atomized chip oil environment. Generally, it needs to be replaced after one month of use due to loose clamps, resulting in inaccurate loading and unloading, which leads to low utilization rate of the sharpening equipment and high maintenance costs. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Summary of the invention
