Description

Technical Field

[0001] The utility model relates to the technical field of spark machines, in particular to a spark machine for processing electronic product shells. Background Art

[0002] A spark machine is a specialized metal-cutting machine. It is primarily used to process conductive materials through electro-erosion, particularly those that are difficult to machine using traditional machining methods due to their high hardness. The spark machine operates by utilizing the electro-erosion effect generated by pulsed discharges between the electrode and the workpiece to remove material, thereby achieving machining. In the manufacturing of electronic product casings, some complex designs, such as those containing small or deep holes or narrow slits, may not meet the requirements of traditional machining methods. This is where spark machines can demonstrate their unique advantages.

[0003] The existing Chinese patent (CN211465087U) discloses a spark machine for processing electronic product shells, including a support frame, a discharge box fixedly installed on the top of the support frame, and a fixed plate fixedly installed on the bottom of the inner cavity of the discharge box, three slide grooves are opened on the top of the fixed plate, and the inner part of the slide groove is clamped with a clamping plate, the middle part of the clamping plate is threadedly sleeved with an adjusting screw, and the top of the adjusting screw is fixedly mounted with a handwheel. The driving motor drives the driving worm gear to rotate, thereby driving the transmission worm engaged with the outer edge of the driving worm gear to rotate. Since the bottom end of the transmission worm gear is movably sleeved with the protective cover, when the transmission worm gear rotates, the transmission worm gear will move up and down, driving the protective cover to move up and down. When the workpiece is subjected to discharge treatment, the protective cover isolates the workpiece, reducing the harm of the molten metal solution to the workers, solving the problem that the previous protective device was not in place and easily caused harm to the workers, reducing the probability of safety accidents, and further improving work efficiency.

[0004] In the above technical solution, in order to reduce the harm of the molten metal solution to the workers, a protective cover is installed on the outside of the discharge head. However, the protective cover in the above technical solution is an integral cover on the outside of the discharge box, which is not conducive to the cooling of the cooling oil inside the discharge box. It is easy to cause the cooling oil temperature to be high, causing the workpiece or electrode material to expand, affecting the processing accuracy, and also affecting the discharge stability of the spark machine.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 5The utility model provides a technical solution: a spark machine for processing electronic product shells, comprising: a cabinet 1 and a discharge box 2, the discharge box 2 is provided on the top of the cabinet 1, a T-slot workbench 4 is provided inside the discharge box 2, an X-axis linear slide 6 is provided on one side of the top of the cabinet 1, a vertical plate 7 is provided above the X-axis linear slide 6, a horizontal plate 8 is provided on the top of the vertical plate 7, a Y-axis linear slide 9 is provided at the bottom of the horizontal plate 8, a Z-axis linear slide 10 is provided at the bottom of the Y-axis linear slide 9, a lifting block 11 is provided on one side of the Z-axis linear slide 10, a discharge head 13 is provided at the bottom of the lifting block 11, a guide sleeve 14 is provided on the outside of the lifting block 11, a guide column 17 is provided at the bottom of the guide sleeve 14, a conical protective cover 15 is provided at the bottom end of the guide column 17, the conical protective cover 15 is located outside the bottom end of the discharge head 13, and a floating ring 16 is provided at the bottom end of the conical protective cover 15. The three-axis movement of the discharge head 13 is achieved through the X-axis linear slide 6, the Y-axis linear slide 7 and the Z-axis linear slide 10. During the movement of the discharge head 13, the discharge head bracket 12 fixed thereto also moves together, and the conical protective cover 15 also moves with the discharge head 13 driven by the discharge head bracket 12. The conical protective cover 15 is used to shield and protect splashes that may occur during the electrospark machining process to avoid damage to personnel. At the same time, the conical protective cover 15 only covers the area around the discharge head 12 and does not block the rest of the discharge box 2, thereby facilitating the cooling and heat dissipation of the cooling oil in the discharge box 2, avoiding the problem of inaccurate machining caused by high temperature of the cooling oil and affecting the discharge stability of the discharge head.

[0024] An oil drain valve is provided at the bottom of one side of the discharge box 2 for circulating the cooling oil. A workbench pad 3 is provided on the inner wall of the bottom of the discharge box 2, and a T-slot workbench 4 is fixed on top of the workbench pad 3. The electronic product housing is fixed to the T-slot workbench 4 by T-bolts.

[0025] A guide hole is defined within the guide sleeve 14, above the guide post 17. A spring 18 is mounted on the outside of the guide post 17. The top end of the spring 18 is connected to the guide sleeve 14, while the bottom end is connected to the top of the conical protective cover 15. There are four guide posts 17, evenly spaced circumferentially around the bottom of the guide sleeve 14. During the protection of the conical protective cover 15, the float ring 16 is constantly in contact with the cooling oil. This creates buoyancy, driving the guide post 17 to expand and contract within the guide hole of the guide sleeve 14. This allows the conical protective cover 15 to automatically float and rise within a lower range, buffering the impact of the cooling oil.

[0026] A slide block 5 is provided on one side of the top of the cabinet 1, and an X-axis linear slide 6 is fixed on top of the slide block 5.

[0027] The conical protective cover 15 is made of transparent plastic, which makes it easy to observe the working status of the discharge head 13. Transparent glass can also be used. These materials need to meet the characteristics of insulation and high temperature resistance to avoid affecting the processing. A through hole is opened in the center of the top of the conical protective cover 15, and an insulating rubber pad is provided between the inside of the through hole and the outer wall of the discharge head 13. The floating ring 16 is an inflatable rubber ring.

[0028] A discharge head bracket 12 is provided at the bottom of the lifting block 11 , a discharge head 13 is fixed to the bottom of the discharge head bracket 12 , and a guide sleeve 14 is fixed to the outside of the discharge head bracket 12 for a stable and convenient connection of the discharge head 13 .

[0029] When the spark machine is used to process the housing of an electronic product, the housing of the electronic product is fixed to the T-slot workbench 4 by a T-bolt. When the spark machine processes the housing, the three-axis movement of the discharge head 13 is realized by the X-axis linear slide 6, the Y-axis linear slide 7 and the Z-axis linear slide 10. During the movement of the discharge head 13, the discharge head bracket 12 fixed thereto also moves together, and the conical protective cover 15 also moves with the discharge head 13 driven by the discharge head bracket 12. The conical protective cover 15 is used to shield and protect splashes that may occur during the electric spark machining process to avoid damage to personnel. At the same time, the conical protective cover 15 only covers the area around the discharge head 12, and does not block the rest of the discharge box 2, thereby facilitating the cooling and heat dissipation of the cooling oil in the discharge box 2, avoiding the problem of inaccurate machining caused by the high temperature of the cooling oil and affecting the discharge stability of the discharge head.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
