Description

Technical Field

[0001] The invention relates to the technical field of gear blank cutting, and in particular to a wind power gear blank cutting device and a cutting method thereof. Background Art

[0002] Gears refer to mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. The working principle of gears is to use the torque transmission after the tooth surfaces mesh to complete transmission and control work. The teeth of the two gears need to bite tightly together. When one gear rotates, it will drive the other gear to rotate in the opposite direction, thereby transmitting power to the next gear. When the gears are produced, a cutting device is needed to cut the gear blanks;

[0003] Patent number CN219648826U is a wind power gear blank cutting device, which is provided with a clamping mechanism, and the gear blank to be cut is clamped by the cooperation of the first clamping plate and the second clamping plate. As the electric push rod is lowered, the saw blade starts to cut the gear blank, and at this time, the damping rod is gradually inserted into the inside of the mounting plate. Under the elastic action of the spring, the second clamping plate clamps the gear blank stably, so as to prevent the tail end of the blank from vibrating with the cutting of the cutting machine, causing cutting deviation and producing waste;

[0004] However, after the gear blank is cut on the base plate, when the cutting work needs to be continued, the operator is required to move the gear blank on the first clamping plate of the base plate and move the material to the bottom of the saw blade. In addition, according to the thickness of the cut gear, the position of the gear blank needs to be adjusted when moving the gear blank before cutting. This is not only time-consuming and labor-intensive, but also reduces work efficiency. Summary of the invention
