Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4 This utility model provides a technical solution: a fully automatic hydraulic four-column inverted deep hole drilling machine, including a frame 1, a mounting base 9 fixedly connected to the bottom of the frame 1, a fixed plate 2 fixedly installed on the top left side of the frame 1, support columns 5 fixedly connected to the four corners of the bottom side of the fixed plate 2, the bottom ends of the four sets of support columns 5 fixedly connected to the mounting base 9, a sliding plate 6 and a sliding plate 8 are provided between the fixed plate 2 and the mounting base 9, the four corners of the sliding plate 6 and the sliding plate 8 are respectively slidably sleeved on the four sets of support columns 5, four sets of connecting pipes 7 are fixedly connected between the sliding plate 6 and the sliding plate 8, and the four sets of connecting pipes 7 are respectively slidably sleeved on the four sets of support columns 5, a lifting component for lifting the sliding plate 6 is installed on the fixed plate 2, a clamping component for fixing the workpiece is installed on the sliding plate 8, and a drilling component for workpiece processing is installed on the mounting base 9.
[0021] When this fully automatic hydraulic four-column inverted deep hole drilling machine is in use, the lifting assembly pushes the sliding plate 6 to rise and fall on the four sets of support columns 5, thereby driving the sliding plate 8 to rise and fall on the four sets of support columns 5 through the four sets of connecting pipes 7. The workpiece is fixed by the clamping assembly installed on the sliding plate 8. Since the four sets of connecting pipes 7 are respectively slidably sleeved on the four sets of support columns 5, the sliding stability and high precision of the sliding plate 6 and the sliding plate 8 are achieved during the processing. It can effectively resist various external forces and vibrations, and ensure that a stable feed state is maintained at all times during processing. The clamped workpiece gradually descends to contact the drilling assembly to complete the processing.
[0022] The lifting assembly includes a hydraulic cylinder 3, which is fixedly mounted on a fixed plate 2. A drive shaft 4 is mounted on the output end of the hydraulic cylinder 3, and the bottom end of the drive shaft 4 is fixedly connected to the top side of the sliding plate 6.
[0023] When the lifting assembly is in use, it is lifted by pushing and pulling the sliding plate 6 through the transmission shaft 4 at the bottom of the hydraulic cylinder 3.
[0024] The clamping assembly includes a clamp 19, which is fixedly installed on the top side of the sliding plate 28. Three sets of clamping plates 20 are slidably installed on the sliding plate 28.
[0025] When in use, the clamping assembly clamps the workpiece from the side by means of three sets of clamping plates 20 that are slidably mounted on the clamp 19.
[0026] The drilling assembly includes a variable frequency speed control motor 14, which is fixedly installed on the top right side of the mounting base 9. A rotating shaft 10 is rotatably installed on the left side of the mounting base 9. A drill bit 21 is installed at the top of the rotating shaft 10. A synchronous pulley 16 is fixedly sleeved at the bottom of the rotating shaft 10. A synchronous pulley 17 is fixedly sleeved at the output shaft end of the variable frequency speed control motor 14. A synchronous belt 18 is tensioned and sleeved between the synchronous pulley 16 and the synchronous pulley 17. A chip removal mechanism is also installed on the mounting base 9.
[0027] The chip removal mechanism includes a chip collection box 15, which is located on the bottom side of the mounting base 9. A chip ejector 11 is fitted on the outer surface of the rotating shaft 10 and is connected to the chip collection box 15. A coolant nozzle 22 is provided at the top of the drill bit 21.
[0028] When the drilling assembly is in use, the variable frequency speed control motor 14 rotates the synchronous pulley 17, which in turn rotates the synchronous pulley 16 connected by the synchronous belt 18, thereby driving the rotating shaft 10 to rotate. The drill bit 21 at the top of the rotating shaft 10 performs drilling on the workpiece. During the drilling process, coolant is sprayed out through the coolant nozzle 22 at the top of the drill bit 21 to cool the drill bit 21. The chips are transported to the waste chip collection box 15 for collection by the chip conveyor 11 fitted on the outer surface of the rotating shaft 10.

A PLC controller is installed inside the control cabinet 12. Processing parameters are set through the touch screen on the human-machine interface 13, and the PLC controller inside the control cabinet 12 realizes the fully automatic control of the deep hole drilling machine, which simplifies the operation process and reduces the difficulty and labor intensity of operation.
[0030] Working Principle: When this fully automatic hydraulic four-column inverted deep hole drilling machine is in use, the transmission shaft 4 at the bottom of the hydraulic cylinder 3 pushes and pulls the sliding plate 6 up and down on the four sets of support columns 5. This, in turn, drives the sliding plate 8 up and down on the four sets of support columns 5 via the four sets of connecting pipes 7. The workpiece is clamped from the side by three sets of clamping plates 20 slidably mounted on the fixture 19. Because the four sets of connecting pipes 7 are slidably sleeved on the four sets of support columns 5, the sliding stability and high precision of the sliding plates 6 and 8 are achieved during processing. This effectively resists various external forces and vibrations, ensuring a stable feed state throughout the processing. The clamped workpiece gradually descends, and the variable frequency speed control motor 14 rotates the synchronous pulley 17, which in turn rotates the tensioned coupling connected by the synchronous belt 18. Synchronous pulley 16 drives the rotating shaft 10 to rotate, and the drill bit 21 at the top of the rotating shaft 10 drills the workpiece. During the drilling process, coolant is sprayed out through the coolant nozzle 22 at the top of the drill bit 21 to cool the drill bit 21. The chips are transported to the waste chip collection box 15 by the chip conveyor 11 sleeved on the outer surface of the rotating shaft 10. The high-pressure coolant can also effectively break up the drill chips, making them easier to discharge, further optimizing the chip removal effect. The deep hole drilling machine sets the processing parameters through the touch screen on the human-machine interface 13, and realizes the fully automatic control of the deep hole drilling machine through the PLC controller inside the control cabinet 12, which simplifies the operation process and reduces the difficulty and labor intensity of operation.
