Description

Technical Field

[0001] The present invention belongs to the field of tool accessories and relates to a tool grinding workbench structure, and in particular to a multi-station machine suitable for robot processing tool handles, which enables a work machine to cooperate with a robot to complete multiple tool grinding processes, avoiding the problem of multiple machine changes required for multiple processing by the robot, thereby reducing processing efficiency. Background Art

[0002] The existing one-piece forged knife not only needs to grind the blade, but also needs to grind its handle. There are the following ways to grind the knife handle in the prior art:

[0003] For example, Chinese patent CN202022772456.3 discloses an efficient automatic grinder for knife and scissors handles, comprising a grinding box with supporting legs welded at the four corners of the bottom, a hydraulic cylinder is installed on the top center inner wall of the grinding box by bolts, and a mounting frame is welded on the bottom outer wall of the output shaft of the hydraulic cylinder, springs distributed at equal distances are welded on the bottom outer wall of the mounting frame, and the same upper pressure strip is welded on the bottom outer walls of multiple springs, and the same lower pressure strip located below the upper pressure strip is welded on the inner walls on both sides of the grinding box, grinding mechanisms distributed at equal distances are arranged in the mounting frame, and multiple grinding mechanisms each include a transmission shaft inserted in the mounting frame in a horizontal direction; since multiple grinding mechanisms are arranged and driven by a grinding motor, multiple grinding mechanisms can work together at the same time, which not only saves electricity resources and reduces the use cost, but also improves work efficiency, reduces the labor burden of workers, and is conducive to efficient production;

[0004] For example, Chinese patent CN201621397139.5 discloses an automatic handle grinding machine for grinding knife handles, comprising a grinding mechanism and a pressing mechanism placed on the grinding mechanism, the grinding mechanism comprising a grinding assembly, the grinding assembly comprising a support frame and a grinding belt transmission assembly arranged on the support frame, the grinding belt transmission assembly comprising a grinding belt, the pressing mechanism being installed above the grinding mechanism, the pressing mechanism comprising a mounting plate, a main body seat placed on the mounting plate, a fixing frame and a holding assembly, the main body seat being installed on the mounting plate, a channel being formed in the main body seat, the channel being arranged crosswise with the conveying direction of the grinding belt, the holding assembly comprising a pressing plate, the pressing plate being elastically arranged in the channel, and a clamping gap being formed between the pressing plate and the grinding belt, so as to grind the knife handle when the knife handle passes through the clamping gap after being conveyed into the channel by the grinding belt; the above-mentioned automatic handle grinding machine for grinding knife handles can automatically grind the knife handle through the grinding mechanism and the pressing mechanism installed on the grinding mechanism, thereby reducing labor and improving production efficiency;

[0005] It can be seen that through the search of the above-mentioned prior art, it was found that although there is a corresponding multi-station grinding structure for the tool handle in the prior art, the above-mentioned multi-station structure can only realize the grinding of the same process and the same part. After the grinding is completed, the tool needs to be transported to the next station by manpower or robot for the next process.
