[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides an embodiment: a drilling device for processing a power distribution cabinet, comprising a bottom box 1 and a side plate 2 fixed on an outer wall of one side of the bottom box 1, and an upper drilling shaft 12 is rotatably installed on the outer wall of one side of the side plate 2 close to the bottom box 1, two symmetrical guide plates 3 are fixed on one side of the top of the bottom box 1, an upper slide 6 is rotatably installed between the two guide plates 3, a dovetail rail is fixed on the top of the guide plate 3, and two sliding sleeves are installed on both sides of the bottom end of the upper slide 6, the sliding sleeve and the dovetail guide rail are slidably matched, and the sliding stability of the upper slide 6 is improved by the dovetail guide rail and the sliding sleeve;

[0019] A transmission box 7 is fixed to one side of the top of the upper slide 6, a lower drill shaft 13 is rotatably mounted on the outer wall of one side of the transmission box 7, and a pulley driving assembly 8 for driving the lower drill shaft 13 to rotate is arranged inside the transmission box 7;

[0020] A spline telescopic transmission shaft is rotatably installed on the outer wall of the transmission box 7 above the lower drill shaft 13, one end of the spline telescopic transmission shaft is connected to the output end of the pulley drive assembly 8, and the other end of the spline telescopic transmission shaft is installed with a pulley transmission structure 11 for driving the upper drill shaft 12 to rotate, and a screw linear module 4 for driving the upper slide 6 to move horizontally is installed inside the bottom box 1, and a rotating driving member for driving the screw linear module 4 to work is installed on the outer wall of one side of the bottom box 1, a plate-shaped tooling 15 is slidably installed on one side of the top of the bottom box 1, a secondary push plate 14 is installed on the outer wall of one side of the upper slide 6, and a PLC control panel 16 electrically connected to the input end of the pulley drive assembly 8 is installed on one side of the surface of the bottom box 1;

[0021] The rotating driving part is a servo motor 5 installed on the outer wall of one side of the bottom box 1. The output end of the servo motor 5 is fixedly connected to the top of the screw in the screw linear module 4. When the screw linear module 4 pushes the upper slide 6, the secondary push plate 14, the lower drill shaft 13 and other components close to the plate-shaped tooling 15 and the plate, the synchronous rotation design can ensure the position and size consistency of the upper and lower rows of holes, reduce the errors that may be caused by manual operation, and improve the processing accuracy and consistency;

[0022] The spline telescopic transmission shaft includes an inner spline shaft 10 rotatably mounted on the outer wall of one side of the side plate 2, and a spline outer shaft 9 rotatably mounted on the outer wall of one side of the transmission box 7. One end of the spline outer shaft 9 extends to the inside of the inner spline shaft 10 and slidably cooperates with the inner spline shaft 10. When the pulley drive assembly 8 transmits rotary power to the upper drill shaft 12, the horizontal pushing action of the screw linear module 4 will change the overall length of the spline outer shaft 9 and the inner spline shaft 10, and ensure that the spline outer shaft 9 and the inner spline shaft 10 ensure that the rotary power of the pulley drive assembly 8 can be transmitted to the pulley transmission structure 2 11 and the upper drill shaft 12. The structure is simple, the operation is stable and reliable, and the driving process is completed by only one motor, which can effectively reduce the construction cost and use cost of the device.

[0023] The pulley drive assembly 8 includes a servo motor 801 installed on the outer wall of one side of the transmission box 7, and a pulley transmission structure 802 for connecting the spline outer shaft 9 and the guide plate 3. The pulley transmission structure 802 includes a synchronous wheel installed on the same end of the surface of the lower drill shaft 13 and the spline outer shaft 9, and a multi-V belt connecting the two synchronous wheels. The pulley drive assembly 8 drives the spline outer shaft 9 to rotate through the servo motor 801, and a part of the power of the pulley drive assembly 8 is transmitted to the lower drill shaft 13 through the pulley transmission structure 802, so that the lower drill shaft 13 and the upper drill shaft 12 rotate synchronously;

[0024] The plate-like tooling 15 includes rectangular guide rails 1501 fixed on both sides of the top of the bottom box 1, and C-mouth sleeves 1502 slidably installed on the upper surface of the rectangular guide rails 1501. Clamps 1503 are fixed on both sides of the top of the C-mouth sleeve 1502. The staff places the outer shell panel between the two clamps 1503. When the lower drill shaft 13 is drilling, the staff holds the clamps 1503 and the C-mouth sleeve 1502 and keeps the outer shell panel stationary. When the lower drill shaft 13 completes the drilling operation and the upper drill shaft 12 needs to continue drilling, the staff no longer holds the clamps 1503 to ensure that the secondary push plate 14 can smoothly push the panel and the plate-like tooling 15.

[0025] When the embodiment of the present application is in use, first, the staff clamps the housing panel of the distribution cabinet to be subjected to double-row and double-line punching operations in the plate-shaped tooling 15, and makes the housing panel be in an upright state. After the position debugging of the housing panel is completed, the staff turns on the pulley drive assembly 8 through the PLC control panel 16 to work, and then a part of the rotational power of the pulley drive assembly 8 is transmitted to the lower drill shaft 13, and the other part of the rotational power is transmitted to the spline telescopic transmission shaft, and then the spline telescopic transmission shaft drives the upper drill shaft 12 to rotate synchronously through the pulley transmission structure 2 11. At this time, the upper drill shaft 12 and the lower drill shaft 13 arranged opposite and up and down rotate synchronously. Then the staff turns on the servo motor 15 through the PLC control panel 16, and the servo motor 15 drives the screw linear module 4 to move, so that the nut moving end of the screw linear module 4 drives the upper slide 6, the transmission box 7, the pulley drive assembly 8 and the lower drill shaft 13 and other components to move toward the housing panel until the end of the lower drill shaft 13 passes through the outside of the housing panel. During this process, the staff needs to use their hands to support the plate-shaped tooling 15 and the outer shell plate to prevent the outer shell plate and the plate-shaped tooling 15 from slipping, and the upper drilling shaft 12 is still rotating synchronously driven by the transmission components. When the secondary push plate 14 is against the outer wall of the plate-shaped tooling 15, the staff's hands no longer apply force to the outer shell plate and the plate-shaped tooling 15, and the upper slide 6 and the secondary push plate 14 continue to move to the right, and will synchronously push the outer shell plate and the plate-shaped tooling 15 to move horizontally until the end of the upper drilling shaft 12 is drilled out of the outside of the outer shell plate due to rotation. At this time, the outer shell plate forms two upper and lower hole positions, and then the screw linear module 4, the transmission box 7 and other components in the device are reset, and the staff pushes the outer shell plate in the Y-axis direction and performs the punching operation of the next hole position according to the above steps, thereby forming two rows of upper and lower and double-line multiple hole positions. By realizing the synchronous punching of the upper and lower rows of hole positions, the task that originally required two times can be completed in one operation, especially in mass production, which can effectively reduce the production cycle and significantly improve production efficiency.
