[0020] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a double-head spark machine with tool magazines installed on both sides, including a machine base 1, a workbench 2, a support base 3, an X-axis slide 4, a Y-axis slide 5, a vertical frame 6, an electrode main shaft 7 and a tool magazine assembly. A workbench 2 is arranged on one side of the machine base 1, a support base 3 is arranged on the upper surface of the machine base 1, two X-axis slides 4 are slidably arranged on the upper surface of the support base 3, and the X-axis slide 4 and the support base 3 are connected by a guide rail and a linear motor in cooperation to realize the movement of the X-axis slide 4 along the guide rail arranged along the X-axis. Y-axis slides 5 are slidably arranged on the upper surfaces of the X-axis slides 4, and the Y-axis slide 5 and the X-axis slide 4 are connected by a guide rail and a linear motor in cooperation to realize the movement of the Y-axis slide 5 along the guide rail arranged along the Y-axis. A vertical frame 6 is arranged at one end of the Y-axis slide 5 close to the workbench 2, and an electrode main shaft 7 is slidably arranged at the outer end of the vertical frame 6. The electrode main shaft 7 and the vertical frame 6 are connected by a guide rail, a servo motor and a lead screw pair in cooperation to realize the lifting of the electrode main shaft 7 along the guide rail arranged along the Z-axis. Tool magazine assemblies are arranged at both ends of one side of the support base 3 close to the workbench 2 through connecting frames 8;

[0021] The tool magazine assembly includes a fixing plate 9, guide rods 10, a cylinder 11, a sliding frame 12, a support plate 13, a reduction motor 14, a gear steering box 15, a turntable 16 and a tool support 17. A number of guide rods 10 are arranged on the surface of the fixing plate 9, a cylinder 11 is arranged at the middle position on the surface of the fixing plate 9, and the piston rod of the cylinder 11 is connected to the sliding frame 12. Both sides of the sliding frame 12 are slidably matched with the guide rods 10 through guide blocks. The cylinder 11 and the guide rods 10 are respectively installed at both ends of the front side surface of the fixing plate 9. The cylinder 11 is horizontally arranged between the two guide rods 10, and the piston rod of the cylinder 11 faces the electrode main shaft 7 corresponding to the guide rod 10. This structure first ensures the stability of the sliding frame 12, and at the same time, the cylinder 11 is located outside the fixing plate 9 to avoid affecting the movement of the electrode main shaft 7. A support plate 13 is arranged at the bottom of the sliding frame 12, an extension frame 18 is arranged on one side of the support plate 13, a reduction motor 14 is arranged on the upper surface of the support plate 13, a gear steering box 15 is installed on the lower surface of the support plate 13, and the gear steering box 15 is also connected to the lower surface of the extension frame 18. The output shaft of the gear steering box 15 faces downward and is connected to a turntable 16. A number of tool supports 17 are evenly arranged on the periphery of the turntable 16. A U-shaped support groove 21 is opened at the outer end of the tool support 17 to realize the support of the tool. The output shaft of the reduction motor 14 and the input shaft of the gear steering box 15 are located on the same side and are both installed with toothed belt wheels 19, and the toothed belt wheels 19 are connected by a toothed belt 20 in cooperation to realize the linkage between the reduction motor 14 and the gear steering box 15.

[0022] Installation method and operating principle: First, assemble the tool magazine assembly. Install the gear gearbox 15 on the lower surfaces of the pallet 13 and the extension frame 18, and install the reduction motor 14 on the upper surface of the pallet 13. Then connect the turntable 16 to the output shaft of the gear gearbox 15, and at the same time connect the belt pulleys 19 on the input shaft of the gear gearbox 15 and the output shaft of the reduction motor 14 through the toothed belt 20 to achieve the linkage between the reduction motor 14 and the gear gearbox 15. Next, install the cylinder 11 and the guide rod 10 on the outer surface of the fixed plate 9. At the same time, connect the sliding frame 12 to the guide rod 10 through the slider, and connect the sliding frame 12 to the piston rod of the cylinder 11 to complete the assembly of the tool magazine assembly. Then install the two tool magazine assemblies on both ends of the front and side surfaces of the support base 3 through the connecting frame 8 respectively. Finally, slide the X-axis slide 4 on the upper surface of the support base 3 through the linear motor and the guide rail, install the Y-axis slide 5 on the upper surface of the X-axis slide 4 through the guide rail and the linear motor, and then install the electrode spindle 7 on the outside of the vertical frame 6 through the cooperation of the guide rail, the servo motor and the lead screw pair to complete the installation. During use, the piston rod of the cylinder 11 retracts, driving the sliding frame 12 and the turntable 16 to move to the outer sides of both ends of the spark machine. When a tool needs to be replaced, the electrode spindle 7 descends, so that the old tool is at the same height as the turntable 16. The old tool is aligned with the tool support 17 at the tool replacement position through the Y-axis slide 5. Then, the X-axis slide 4 drives the electrode spindle 7 to move to the corresponding tool support 17. At this time, the top of the tool is inserted into the U-shaped support groove 21 of the tool support 17, and the jaws of the electrode spindle 7 are loosened, and the old tool falls off. The electrode spindle 7 rises, and the reduction motor 14 drives the gear gearbox 15 to rotate, thereby driving the turntable 16 to rotate. The next tool support 17 with a tool rotates to the lower part of the electrode spindle 7. The electrode spindle 7 descends and cooperates with the new tool. After the jaws are clamped, the tool replacement is completed. The structure of the present utility model is reasonable. Tool magazine assemblies are provided on both sides of the double-bullhead spark machine located on the support base 3, which is convenient for the two bullheads to replace tools separately without mutual influence, greatly improving the convenience. At the same time, the turntable 16 of the tool magazine assembly moves along the guide rail together with the sliding frame 12 through the gear gearbox 15. When working normally, the turntable 16 is moved to the outer position through the cylinder 11, thus ensuring the machining range of the bullhead.

[0023] For those parts not detailed in the present utility model, they are all well-known technologies to those skilled in the art.

[0024] 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.
