[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution: a five-head electro-discharge machining machine tool, including an oil tank 1, a workbench 2, a fixed seat 3, a ram 4 and a bull head 5. The workbench 2 is arranged inside the oil tank 1. The workbench 2 is provided with a number of adjustment openings 10. The bottom of the workbench 2 is supported and guided by a screw structure. Through the adjustment openings 10, the operator can directly adjust the screw, thereby adjusting the height of the workbench 2. Lifting doors 8 are arranged at both ends of the oil tank 1. Through the lifting doors 8, the workpiece can be placed and taken out. Fixed seats 3 are arranged on both sides of the oil tank 1. An X-axis linear motor stator 6 is arranged at the middle position of the upper surface of the fixed seat 3. Two rams 4 are arranged on one side of the fixed seat 3 through linear guide rails 7, and three rams 4 are arranged on the other side of the fixed seat 3 through linear guide rails 7. The bottoms of the rams 4 are all matched with the corresponding X-axis linear motor stators 6 through linear motor rotors. Bull heads 5 are arranged on the sides of the rams 4 close to the oil tank 1. The length of the linear guide rail 7 is the same as that of the X-axis linear motor stator 6. The width of the ram 4 along the length direction of the X-axis linear motor stator 6 multiplied by 6 is equal to the length of the X-axis linear motor stator 6. Oil storage tanks 9 are arranged on both sides of the fixed seat 3. The oil storage tanks 9 are cooperated with the inside of the oil tank 1 through oil pumps to realize the supply and recovery of cooling oil during the machining of workpieces.

[0020] As Figure 3As shown in the figure, the bull head 5 includes a longitudinal sleeve 501, a Z-axis main shaft 502, an electrode 503 and a Y-axis telescopic arm 504. The Z-axis main shaft 502 is movably arranged in the longitudinal sleeve 501 through the cooperation of a motor and a lead screw. An electrode 503 is arranged at the bottom of the Z-axis main shaft 502. A Y-axis telescopic arm 504 is also arranged on one side of the longitudinal sleeve 501. The ram 4 is provided with an inner cavity. The Y-axis telescopic arm 504 is movably connected to the inner cavity of the ram 4 through a linear motor. The telescoping of the bull head 5 is realized through the linear motor. Through the cooperation of the motor and the lead screw, and then through the cooperation of the Z-axis main shaft 502 and the longitudinal sleeve 501, the control of the height of the Z-axis main shaft 502 along the height of the longitudinal sleeve 501 is realized, so as to realize the adjustment of the height of the electrode 503.

[0021] Working method and principle: First, the workbench 2 is installed in the oil tank 1 through a screw rod. The adjustment of the screw rod is realized through the adjustment port 10 of the workbench 2, so as to determine the height of the workbench 2. Then, two rams 4 are installed on the fixed seat 3 on one side and are slidably matched with the corresponding linear guide rails 7. At the same time, the linear motor movers at the bottoms of these two rams 4 are matched with the corresponding X-axis linear motor stators 6. The other three rams 4 are installed on the fixed seat 3 on the other side and are slidably matched with the corresponding linear guide rails 7. At the same time, the linear motor movers at the bottoms of these three rams 4 are matched with the corresponding X-axis linear motor stators 6. The positions of the oil storage tanks 9 correspond to the rams 4 one by one, and the installation is completed. During use, the workpiece is fixed on the upper surface of the workbench 2, and electric discharge machining is carried out through five rams 4. Since the lengths of the linear guide rails 7 and the X-axis linear motor stators 6 are the same and the width of the ram 4 along the length direction of the X-axis linear motor stator 6 multiplied by 6 is equal to the length of the X-axis linear motor stator 6, the lengths of the linear guide rails 7 and the X-axis linear motor stators 6 are 6 times the width of the ram 4. When one or more straight lines are machined on the workpiece, the five rams 4 can be staggered with each other, and the five electrodes 503 are located on the same straight line. Subsequently, they move synchronously along the direction of the X-axis linear motor stator 6. After walking the width of one ram 4, the machining of one straight line is completed. For example Figure 4As shown; it is also possible to process multiple horizontal lines. Similarly, the bull head 5 moves along the length direction of the ram 4 through the cooperation of the linear motor inside the ram 4, so that the processing of five horizontal lines can be realized. Then, the five rams 4 move synchronously along the direction of the motor stator to complete the processing of another five horizontal lines, and so on. Similarly, it can also be used for the processing of irregular shapes, and the efficiency of the five bull head 5 structure is further improved. The structure of the present utility model is reasonable. It adopts the five bull head 5 structure, and each bull head 5 is connected in cooperation with a ram 4. Among them, two rams 4 are connected in cooperation with the fixed seat 3 on one side through the linear guide rail 7 and the X-axis linear motor stator 6, and the other three rams 4 are connected in cooperation with the fixed seat 3 on the other side through the linear guide rail 7 and the X-axis linear motor stator 6. Moreover, the length of the linear guide rail 7 and the X-axis linear motor stator 6 is 6 times the width of the ram 4, so that all the rams 4 can move a width of a ram 4 when processing a straight line. On the one hand, it can realize the synchronous processing of the head-to-tail connection of adjacent two bull heads, greatly improving the efficiency compared with the traditional bull head type electric discharge forming machine tool, and greatly improving the efficiency compared with the traditional single bull head 5 or double bull head 5 electric discharge forming machine tool, and without wasting the overall space. On the other hand, a distance equal to the width of a ram is reserved, which does not affect the movement between the bull heads and can also meet the daily processing requirements.

[0023] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
