Description

TECHNICAL FIELD

[0001] The utility model relates to cutter grinding technical field more specifically, relate to a blade opening blade equipment. BACKGROUND

[0002] At present in the hard cutter production process, the blade opening blade is completed on the special blade opening blade equipment. The specific steps are as follows: first, the blade is installed on the spindle of the equipment, and is tightly pressed with the nut. Then, the spindle rotates at high speed, and the blade is ground and opened. After the opening blade is completed, the nut is loosened, the blade is removed, and a new blade to be opened is replaced.

[0003] Under the existing manual operation mode, the disassembly of the blade has the problem of low efficiency. The tightening and loosening of the nut are needed every time the blade is installed and disassembled, and this process often needs a long time, about 60 seconds. In contrast, the actual opening blade grinding time of the blade is only 30 seconds. This long auxiliary operation seriously affects the production efficiency; in addition, the nut may also have a negative impact on the quality of the blade. During the tightening and loosening of the nut, relative friction occurs between the nut and the end face of the blade, leaving marks on the end face of the blade. These marks and any small scratches on the surface of the blade will affect the unbalance of the blade, and then cause the vibration of the blade. The vibration of the blade will cause the edge collapse of the cut object to be larger, thereby reducing the quality of the blade.

[0067] In a specific implementation process, the vacuum passes through the spindle gas path 210 along the axial direction of the vacuum rotating spindle 200 to the adsorption jig 400 through the vacuum supply device, and after passing through the jig gas path 401 on the adsorption jig 400, a vacuum negative pressure cavity is formed at the vacuum gas groove 402 on the end face of the adsorption jig 400, so that a vacuum adsorption force is generated to fix the blade 600. At this time, the vacuum rotating spindle 200 rotates at 40000 rpm or other speeds, and the blade 600 is completed. After the blade 600 is sharpened, the connection between the vacuum rotating spindle 200 and the vacuum supply device is temporarily cut off, the blade 600 that has been sharpened is taken off, and a new blade 600 to be sharpened is installed on the adsorption jig 400. At this time, the connection between the vacuum rotating spindle 200 and the vacuum supply device is restored, and the next round of blade 600 sharpening can be performed.
