[0032] The working principle of a blade processing fixture provided by the utility model is as follows:

[0033] Step 1: First, when processing the blade, place the blade on the top of the positioning platform 9. At this time, start the cylinder 7, so that the cylinder 7 can drive the extrusion plate 8 to tightly squeeze the middle of the blade, so that the blade can be squeezed and fixed on the top of the positioning platform 9, so that the blade corners can be suspended and fixed above the positioning platform 9, which brings convenience to the grinding and polishing of the blade corners, avoids the problem that the blade corners are difficult to grind when they are clamped and fixed, and brings convenience to the processing of the blade. When fixing the blade, the anti-slip pad 10 can greatly increase the friction between the fixed blade and the positioning platform 9, so as to avoid the blade Vibration occurs during grinding, causing the blade to tilt and slide, thereby improving the stability of the blade after being fixed. When adjusting the position of the grinding component, start the No. 2 motor 17, so that the No. 2 motor 17 can drive the pulley 5 through the positioning shaft 4 to transmit, that is, drive the No. 1 motor 15 to move, thereby bringing convenience to the grinding of different positions of the blade. When adjusting the position of the grinding component, the sliding ball 18 can support the moving support sleeve 13, so that the support sleeve 13 is prevented from rubbing against the top of the top plate 2 when moving, causing the support column 12 to shake violently, thereby improving the stability of the grinding component when moving;

[0034] Step 2: When it is necessary to grind the edge of the blade, fix the blade on the top of the positioning platform 9, and then start the No. 1 motor 15 so that the No. 1 motor 15 can drive the grinding wheel 16 to rotate rapidly. At this time, the grinding wheel 16 can grind the edge of the blade, thereby achieving the effect of grinding and polishing the edge of the blade. When dust is generated during the blade grinding and polishing, start the dust suction pump 192 so that the dust suction pump 192 can absorb the grinding dust through the dust suction sleeve 194, and then transport it to the dust box 193 for storage, thereby avoiding the problem of air pollution caused by the grinding dust flying around, thereby improving the cleanliness of the blade during processing. When adjusting the working position of the fixture, push the support plate 1 so that the sliding wheel 202 can drive the support plate 1 to move horizontally through the connecting column 201, that is, the horizontal movement effect of the fixture is achieved, thereby facilitating the adjustment of the working position of the fixture.
