Description

Technical Field

[0001] This utility model relates to the field of plate processing technology, and in particular to a plate drilling machine. Background Technology

[0002] When drilling plates, traditional drilling machines typically only allow the drill bit to move in a two-dimensional plane, with a limited range of movement. They cannot be adjusted arbitrarily according to the drilling position on the plate, resulting in low flexibility. Furthermore, the coolant nozzle of the drilling machine is usually set to one and fixed in a certain position, and cannot automatically adjust the spray angle according to the drilling position of the drill bit. This causes the coolant to not be accurately sprayed onto the contact surface between the drill bit and the workpiece, affecting the cooling effect and accelerating drill bit wear.

An electric push rod 11 is provided at the bottom of the motor base 6 to drive the spray pipe 9 to rise and fall. A connecting rod 35 is provided on one side of the spray pipe 9. The telescopic rod of the electric push rod 11 is fixedly connected to the connecting rod 35. By setting up the spray pipe 9, nozzles 10, and electric push rod 11, it can be ensured that the coolant is always accurately sprayed onto the contact surface between the drill bit 8 and the plate 27, thereby improving the cooling effect and extending the service life of the drill bit 8.

[0019] The workbench 1 is equipped with a coolant recovery and utilization mechanism connected to the processing tank 12. The coolant recovery and utilization mechanism includes recovery chambers 32 respectively set inside the workbench 1. The bottom of the processing tank 12 is provided with a through hole 33 communicating with the recovery chamber 32. A filter basket 34 is embedded in the through hole 33. The recovery chamber 32 is connected to the spray pipe 9 through a pump body. By setting up a coolant recovery and utilization mechanism, it is easy to recover coolant, reduce coolant waste, maintain a clean working environment, reduce cleaning workload, and improve production efficiency.

[0020] The top of the workbench 1 is provided with a processing groove 12, and a plate fixing mechanism is provided inside the processing groove 12. The plate fixing mechanism includes a fixed support block 16 and a movable support block 17. The fixed support block 16 is located at the bottom of the processing groove 12 near the groove 2, and the movable support block 17 is slidably located at the other side of the bottom of the processing groove 12. Several cylinders 18 are embedded in the top of the workbench 1, adjacent to the fixed support block 16. The top of the telescopic end of the cylinders 18 is rotatably connected to a lifting plate 19. The bottom of the lifting plate 19 is provided with a pressure rod 20, and the bottom of the pressure rod 20 is provided with a first pressure plate 21. A first adjusting rod 22 is threadedly connected to the side of the workbench 1 away from the fixed support block 16. The first adjusting rod 22 is rotatably connected to the movable support block 17. The top of the movable support block 17 is close to the first adjusting rod 21. One end of the adjusting rod 22 is provided with several columns 23. A horizontal plate 24 is rotatably connected to the top of the columns 23. A second adjusting rod 25 is threaded onto the horizontal plate 24. A second pressure plate 26 is rotatably connected to the bottom of the second adjusting rod 25. The plate 27 is placed on top of the fixed support block 16 and the movable support block 17 and is pressed and fixed by the first pressure plate 21 and the second pressure plate 26. The bottom of the lifting plate 19 is provided with a first connecting sleeve 28, which is rotatably sleeved on the top of the telescopic end of the cylinder 18. A first clamping bolt 29 is threadedly connected to the side wall of the first connecting sleeve 28. The bottom of the horizontal plate 24 is provided with a second connecting sleeve 30, which is rotatably sleeved on the top of the columns 23. A second clamping bolt 31 is threadedly connected to the side wall of the second connecting sleeve 30. By setting up the plate fixing mechanism, the size of the plate 27 can be adjusted to ensure that the plate 27 is stably fixed during drilling, avoiding drilling errors caused by workpiece displacement and improving product quality.

[0021] When this utility model is in operation, the position of the movable support block 17 is adjusted according to the size of the plate 27. Then, the plate 27 is placed on top of the movable support block 17 and the fixed support block 16, and is pressed and fixed by the first pressure plate 21 and the second pressure plate 26. At the same time, the lifting plate 19 is locked by the first clamping bolt 29, and the horizontal plate 24 is locked by the second clamping bolt 31. The longitudinal screw slide guide module 3, the vertical screw slide guide module 4, and the transverse screw slide guide module 5 work to drive the drilling motor 7 to move to the drilling position. At the same time, the spray pipe 9 moves synchronously with the drilling motor 7. When the drill bit 8 drills into the plate 27, the spray pipe 9 can be moved upward by the electric push rod 11 to ensure that the coolant sprayed by the nozzle 10 is directly facing the contact surface between the drill bit 8 and the plate 27. The waste liquid flows into the processing tank 12 and enters the recovery chamber 32 after being filtered by the filter basket 34. Then, it can be pumped back into the spray pipe 9 for use.
