Rotating table 201 is horizontal round table, and is provided with a circular hole in the center, is fixedly sleeved on the output shaft of rotary seat 202, and rotates around the center with the output shaft. Positioning detection device 203 is two vertically arranged travel switches, and is fixedly installed below the front of the mesa of rotating table 201. The lower surface of rotating table 201 is uniformly provided with 4 groups of protrusions indicating angle around, and the trigger end of travel switch is located on the path of protrusion rotating with rotating table 201, and two travel switches are triggered by protrusion at the same time, to determine the rotating position angle of rotating table. Locking device 204 is a bolt cylinder moving in vertical direction, and is fixedly arranged on the mesa of rotating table 201 below the rack 1. The lower surface of rotating table 201 is uniformly provided with bolt holes around, and the bolt of bolt cylinder is inserted into bolt hole after rotating table 201 is rotated to position, and travel switch is triggered, to lock the movement of rotating table 201.

[0027] Clamping mechanism 3 is 4 rectangular hydraulic clamps, and is symmetrically and uniformly distributed on the upper surface of rotating table 201, and is perpendicular to each other, to form 4 symmetrically distributed clamping stations. 5 clamping jaws are slidably connected on each hydraulic clamp, and form 4 clamping positions by cooperation, and each clamping position can independently act and independently clamp workpiece.

[0028] The grinding mechanism 4 is two vertical milling machines arranged symmetrically on the two sides of the rear of the rotary table 201 above the frame 1. The heads of the two vertical milling machines are located above a hydraulic vice respectively, and the machining precision of each vertical milling machine is different, so that rough machining and fine machining can be performed respectively and independently. The two vertical milling machines repeat the respective machining actions to synchronously perform rough machining and fine machining on the workpieces respectively through the rotation switching of the clamping stations.

[0029] The driving mechanism 5 includes a rotary table driving motor 501 and a gear box 502. The rotary table driving motor 501 is fixedly arranged on the frame 1 below the front side of the rotary table 201, the motor shaft is connected with the input end of the gear box 502, and the output end of the gear box 502 is connected with the input end of the rotating shaft of the rotary seat 202 to provide rotary power for the vertical rotating shaft.

[0031] The machining operation process is as follows: taking the gating milling process of the casting as an example, before work, the operator sets the relevant parameters into the control console to program and design the machining link. Then, the rotary table driving motor 501 is driven, the rotary mechanism 2 is manually controlled, the rotary table 201 is rotated to switch the station, and the casting to be machined is firmly clamped on the hydraulic vice of the clamping mechanism 3. The rotary table driving motor 501 is started to drive the rotary table 201 to rotate counterclockwise, the rotary table 201 is positioned through the positioning detection device 203, and the locking device 204 is locked. Next, the right vertical milling machine first acts to perform rough milling on the gating of the casting. After the machining is completed, the equipment opens the locking device 204, rotates counterclockwise by one station, positions and locks. At this time, the right vertical milling machine repeats the rough milling on the casting on the new corresponding station, and the left vertical milling machine simultaneously starts to act to perform fine machining and burr removal on the casting after the rough machining.
