The invention discloses an electric spark machining device and method for a three-degree-of-freedom spherical gear, and belongs to the technical field of machining. The electric spark machining device for the three-degree-of-freedom spherical gear comprises a plurality of first profiling electrode rods, a plurality of second profiling electrode rods, a plurality of first profiling electrode tool heads, a plurality of second profiling electrode tool heads, a plurality of first guide grooves, a plurality of second guide grooves, a rotating shaft and a feeding disc. According to the electric spark machining device and method for the three-degree-of-freedom spherical gear, the curved surface of each side of the used profiling electrode tool head is the conjugate curved surface of a workpiece to be machined, and the machining method and device are suitable for all tooth-shaped gears. The electric spark machining method for the three-degree-of-freedom spherical gear is electric spark machining, finish machining of the workpiece to be machined is completed at a time by controlling the feeding amount of the profiling electrode tool head, machining is one-time machining, the pulse utilization rate is increased, and machining is efficient. According to the electric spark machining device and method for the three-degree-of-freedom spherical gear, rapid production is achieved through the electric heating fusion bonding principle, the profiling electrode tool head is simple in machining path, the efficiency is high, and the device and method are capable of being used for batch machining.
Description
technical field [0001] The invention belongs to the technical field of machining, and in particular relates to an electric discharge machining device and a machining method for a three-degree-of-freedom spherical gear. Background technique [0002] See the master's thesis "Structure Design and Analysis of Spherical Gear CNC Gear Grinding Machine" published by Pan Cunyun and others from the National University of Defense Technology. Tooth surfaces with a precision above grade 6 need to be processed with special grinding tools designed to match the tooth shape, and even the partial tooth surfaces of three-degree-of-freedom spherical gears cannot be finished at all, and the accuracy is greatly affected by processing methods and equipment. Contents of the invention [0003] In order to solve the problem in the prior art that it is difficult to finish the local tooth surface when processing complex tooth surfaces of three-degree-of-freedom spherical gears, the present invention...
