Description

Technical Field

[0001] The invention relates to the technical field of drilling machines, in particular to an auxiliary positioning type air expansion shaft processing drilling machine and a drilling method. Background Art

[0002] Air expansion shafts are usually used for winding and unwinding of coils. Air expansion is used to fix or release the coils. The drilling machine used for processing is a mechanical equipment specially used for processing air expansion shafts. Its main function is to accurately create the required holes on the air expansion shaft.

[0003] For example, a drilling machine for an inflatable shaft with publication number CN115351323B belongs to the technical field of inflatable shaft processing. The drilling machine for an inflatable shaft includes a workpiece clamping assembly for fixing the workpiece, including a clamping component that can move linearly along the X-axis and Y-axis directions at the same time. The movement trajectory of the workpiece is defined by the ratio of the X-axis movement speed and the Y-axis movement speed of the clamping component. The inflatable shaft drilling operation is achieved by combining the X-axis drilling assembly and the Z-axis drilling assembly, and clamping the workpiece in cooperation with a separately arranged workpiece clamping assembly. Only one positioning is required during the processing of the inflatable shaft, thereby improving the positioning accuracy. At the same time, the control of the workpiece movement trajectory can be achieved by controlling the movement speed of the clamping component in the X-axis and Y-axis directions. By switching the tool of the Z-axis drilling assembly, the processing of multi-diameter stepped holes can be achieved, thereby simplifying the processing process of the inflatable shaft.

[0004] A drilling machine for an inflatable shaft in the above technical solution realizes the drilling operation of the inflatable shaft by clamping the workpiece by cooperating the X-axis drilling component and the Z-axis drilling component. Only one positioning is required during the processing of the inflatable shaft, thereby improving the positioning accuracy. In the actual operation process, the inflatable shaft needs to drill holes in different directions on the outside of the shaft body when performing the drilling operation, and the drilling machine in the above technical solution is inconvenient to adjust the rotation angle of the inflatable shaft when performing the drilling operation on the inflatable shaft.

[0005] Another example is a transverse drilling machine with publication number CN107335828B, which includes a base, a pressing assembly and a drilling assembly; the base includes a bottom plate, a first positioning plate and a second positioning plate, the first positioning plate is protruding from one side of the bottom plate, the second positioning plate is protruding from the middle of the bottom plate, the second positioning plate is parallel to the first positioning plate and is spaced apart, a positioning space is formed between the first positioning plate and the second positioning plate, and a plurality of through holes are formed on the second positioning plate; the pressing assembly includes a cross bar, a driving member and a pressing plate, and the transverse drilling machine is not easy to drill off-center.

[0006] A transverse drilling machine in the above technical solution fixes the shaft body by pressing the assembly, and the drilling machine is not easy to drill off-center during drilling operations. In actual operations, when the drilling machine processes the shaft body, especially when processing the pneumatic shaft, it is usually necessary to drill holes at different angles on the outside of the shaft body, and a single drilling operation only processes a single shaft body, which limits the overall processing efficiency.

[0018] A method for drilling a gas expansion shaft comprises the following steps: S1: First, start the hydraulic rod telescopic end to retract, so that the hydraulic rod telescopic rod drives the drilling motor to move upward between the two first installation slots, so that the drilling motor drives the drill bit away from the storage plate until the drilling motor moves to the top of the inner side of the first installation slot. At this time, start the fixed motor to drive the reduction plate to operate, so that the reduction plate drives the positioning screw to rotate inside the storage plate, and at the same time, the positioning screw rotates inside the third threaded hole, and the movable seat is driven to slide inside the storage plate through the rotation of the positioning screw, so that the movable seat and the fixed seat are separated from each other, and one end of the gas expansion shaft is installed inside the fixed seat, so that the end of the gas expansion shaft is fixed inside the rotating sleeve, and at the same time, the gas expansion shaft is lifted up, so that the end of the gas expansion shaft away from the fixed seat points to the movable seat, and at this time, the rotation of the positioning screw is controlled to drive the movable seat to move in the direction close to the fixed seat until the movable seat is installed at the end of the gas expansion shaft away from the fixed seat, and the two ends of the gas expansion shaft are fixed by the fixed seat and the movable seat, and then the gas expansion shaft is fixed on the top of the storage plate; S2: When the air shaft is fixed, the motor that drives the adjusting screw to rotate is started, so that the adjusting screw rotates between the two mounting seats. While the mounting seats rotate, the adjusting screw will rotate inside the second threaded hole, so that the adjusting screw drives the two motion shafts to move outside the second threaded hole by rotating inside the second threaded hole. Since the threads at both ends of the adjusting screw are in opposite directions, when the adjusting screw drives the two motion shafts to move outside the second threaded hole, the two motion shafts always move synchronously in opposite directions. S3: When the two moving axes move away from each other, the two moving axes stretch the two ends of the telescopic frame composed of the four linkage rods, and the two connecting rods rotate around the moving axes at the same time, so that the angle between the two connecting rods is reduced. At the same time, the two connecting rods drive the two linkage rods to rotate around the driven axis through the connecting axis, so that the angle between the two linkage rods toward the moving axis is reduced. At this time, the overall length of the telescopic frame will extend with the movement of the moving axes. During the movement of the moving axes, since the four moving plates are equidistantly distributed, the two moving axes and the two driven axes are equidistantly distributed. The X-shaped structure formed by the two linkage rods restricts the movement of the driven axis and the moving axis, so that the moving axis and the driven axis always maintain an equidistant distribution during the movement. Conversely, when the two moving axes are close, the moving axis and the driven axis will also always maintain an equidistant distribution during the movement, so that the moving plates always maintain an equidistant distribution during the movement of the outer side of the guide track, and the movement distances of multiple moving plates remain consistent. S4: During the movement of the moving plate, the mounting plate will be driven to move, so that the mounting plate drives the two extension rods and the clamping block to move synchronously with it, so that the two clamping blocks and the extending rod drive the storage plate to move with it, until the storage plate moves to a predetermined position. When the storage plate is in motion, the storage plate will drive the fixed seat to move with it, and the rotating sleeve will move with the fixed seat. When the fixed seat drives the rotating sleeve to rotate, it will move on the top of the rack. Since the gear and the rack are meshed with each other, the gear drives the rotating sleeve to rotate inside the fixed seat, thereby driving the air shaft between the fixed seat and the movable seat to rotate; S5: adjusting the distance between the multiple storage plates according to the required rotation angle of the air expansion shaft drilling operation. When the distance between the moving plates is reduced, the space for the moving plates to move is reduced, so that the moving space of the storage plates is reduced, the moving distance of the gear is shortened, and the angle of the gear when driving the air expansion shaft to rotate is reduced. On the contrary, when the distance between the moving plates is increased, the angle of the gear when driving the air expansion shaft to rotate is increased. S6: After the air-expanding shaft is fixed and the distance between the storage plates is adjusted, the telescopic end of the hydraulic rod is started to extend, so that the hydraulic rod drives the drilling motor to move downward. During the downward movement, the drilling motor drives the drill bit to contact the air-expanding shaft to perform a drilling operation on the air-expanding shaft. While the air-expanding shaft is being drilled, the moving beam is driven to move on the bottom frame as a whole by rotating the driving screw, so that the moving beam drives the drill bit to move along the air-expanding shaft, thereby performing a long hole opening operation on the air-expanding shaft. At the same time, the angle of the air-expanding shaft is adjusted by adjusting the distance between the storage plates, so that drilling operations are performed at different angles on the outside of the air-expanding shaft.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The auxiliary positioning pneumatic shaft processing drilling machine and drilling method are provided with a synchronous structure, and the X-shaped structure formed by two linkage rods is used to limit the movement of the driven shaft and the moving shaft, so that the moving shaft and the driven shaft always maintain an equidistant distribution during the movement. Conversely, when the two moving shafts are close, the moving shaft and the driven shaft will also always maintain an equidistant distribution during the movement, so that the moving plate always maintains an equidistant distribution during the movement of the outer side of the guide track. At the same time, the movement distances of multiple moving plates are kept consistent, so that the multiple moving plates can adjust the position of the storage plate on the top of the horizontal track at the same time, so that when the punching machine is processing multiple pneumatic shafts, the multiple pneumatic shafts can move synchronously, reducing the error of the pneumatic shafts during the processing; Furthermore, a fixed structure is provided, and during the movement of the moving plate, the mounting plate is driven to move, so that the mounting plate drives the two extension rods and the clamping block to move synchronously therewith, so that the two clamping blocks and the extension rod drive the storage plate to move therewith, until the storage plate moves to a predetermined position. When the storage plate is in the process of moving, the storage plate drives the fixed seat to move therewith, and the rotating sleeve moves with the fixed seat. During the process of the fixed seat driving the rotating sleeve to rotate, it will move on the top of the rack. Since the gear and the rack are meshed with each other, the gear drives the rotating sleeve to rotate inside the fixed seat, thereby driving the air expansion shaft between the fixed seat and the movable seat to rotate, so that the drilling machine can perform drilling operations on different angles of the air expansion shaft during the drilling operation. Furthermore, the distance between the multiple storage plates is adjusted according to the required rotation angle of the pneumatic shaft drilling operation. When the distance between the moving plates decreases, the space for the moving plates to move is reduced, thereby reducing the movement space of the storage plates, shortening the movement distance of the gears, and reducing the angle of the gears when driving the pneumatic shaft to rotate. Conversely, when the distance between the moving plates increases, the angle of the gears when driving the pneumatic shaft to rotate increases. While realizing the drilling operations at different angles of the pneumatic shaft, the rotation angles of pneumatic shafts of different diameters are controlled at the same time, so that the device can perform precise drilling operations on pneumatic shafts of different diameters.

[0032] Embodiment 2: Based on Embodiment 1, its specific working principle is as follows: First, the telescopic end of the hydraulic rod 23 is started to retract, so that the telescopic rod of the hydraulic rod 23 drives the drilling motor 26 to move upward between the two first installation slots 25, so that the drilling motor 26 drives the drill bit 27 away from the storage plate 30, until the drilling motor 26 moves to the top of the inner side of the first installation slot 25, and then the fixed motor 34 is started to drive the reduction plate 35 to operate, so that the reduction plate 35 drives the positioning screw rod 36 to rotate inside the storage plate 30, and at the same time, the positioning screw rod 36 rotates inside the third threaded hole 40, and the movable seat 33 is driven inside the storage plate 30 by the rotation of the positioning screw rod 36 The movable seat 33 and the fixed seat 32 are slidably connected to each other, and one end of the gas expansion shaft is installed inside the fixed seat 32, so that the end of the gas expansion shaft is fixed inside the rotating sleeve 37. At the same time, the gas expansion shaft is lifted up so that the end of the gas expansion shaft away from the fixed seat 32 points to the movable seat 33. At this time, the rotation of the positioning screw rod 36 is controlled to drive the movable seat 33 to move toward the fixed seat 32 until the movable seat 33 is installed at the end of the gas expansion shaft away from the fixed seat 32. The two ends of the gas expansion shaft are fixed by the fixed seat 32 and the movable seat 33, and then the gas expansion shaft is fixed to the top of the storage plate 30. When the air shaft is fixed, the motor that drives the adjusting screw 14 to rotate is started, so that the adjusting screw 14 rotates between the two mounting seats 13. While the mounting seats 13 rotate, the adjusting screw 14 will rotate inside the second threaded hole 20, so that the adjusting screw 14 drives the two moving shafts 15 to move outside the second threaded hole 20 by rotating inside the second threaded hole 20. Since the threads at both ends of the adjusting screw 14 are in opposite directions, when the adjusting screw 14 drives the two moving shafts 15 to move outside the second threaded hole 20, the two moving shafts 15 always move synchronously in opposite directions. When the two moving shafts 15 move away from each other, the two moving shafts 15 stretch the two ends of the telescopic frame formed by the four linkage rods 18, and the two connecting rods 16 rotate around the moving shaft 15 at the same time, so that the angle between the two connecting rods 16 decreases. At the same time, the two connecting rods 16 drive the two linkage rods 18 to rotate around the driven shaft 19 through the connecting shaft 17, so that the angle between the two linkage rods 18 toward the moving shaft 15 decreases. At this time, the overall length of the telescopic frame will extend with the movement of the moving shaft 15. During the movement of the moving shaft 15, since the four moving plates 11 are equidistant, Distribution, so the two moving shafts 15 and the two driven shafts 19 are equidistantly distributed, and the X-shaped structure formed by the two linkage rods 18 restricts the movement of the driven shaft 19 and the moving shaft 15, so that the moving shaft 15 and the driven shaft 19 always maintain an equidistant distribution during the movement process. Conversely, when the two moving shafts 15 are close, the moving shaft 15 and the driven shaft 19 will also always maintain an equidistant distribution during the movement process, thereby making the moving plate 11 always maintain an equidistant distribution during the movement of the outer side of the guide track 10, and at the same time, the movement distance of multiple moving plates 11 remains consistent; During the movement of the moving plate 11, the mounting plate 24 will be driven to move, so that the mounting plate 24 drives the two extension rods 28 and the block 29 to move synchronously with it, so that the two blocks 29 and the extension rod 28 drive the storage plate 30 to move with it, until the storage plate 30 moves to a predetermined position. When the storage plate 30 is in the process of moving, the storage plate 30 will drive the fixed seat 32 to move with it, and the rotating sleeve 37 will move with the fixed seat 32. In the process of the fixed seat 32 driving the rotating sleeve 37 to rotate, it will move on the top of the rack 41. Since the gear 38 and the rack 41 are meshed with each other, the gear 38 drives the rotating sleeve 37 to rotate inside the fixed seat 32, thereby driving the air shaft located between the fixed seat 32 and the movable seat 33 to rotate. The distance between the plurality of storage plates 30 is adjusted according to the required rotation angle of the air expansion shaft drilling operation. When the distance between the moving plates 11 is reduced, the space for the moving plates 11 to move is reduced, so that the movement space of the storage plates 30 is reduced, so that the movement distance of the gear 38 is shortened, and the angle of the gear 38 when driving the air expansion shaft to rotate is reduced. On the contrary, when the distance between the moving plates 11 is increased, the angle of the gear 38 when driving the air expansion shaft to rotate is increased. After the air-expanding shaft is fixed and the distance between the storage plates 30 is adjusted, the telescopic end of the hydraulic rod 23 is started to extend, so that the hydraulic rod 23 drives the drilling motor 26 to move downward. During the downward movement, the drilling motor 26 drives the drill bit 27 to contact the air-expanding shaft to perform a drilling operation on the air-expanding shaft. While the air-expanding shaft is being drilled, the moving beam 8 is driven to move on the bottom frame 1 as a whole by rotating the driving screw 6, so that the moving beam 8 drives the drill bit 27 to move along the air-expanding shaft, thereby performing a long hole opening operation on the air-expanding shaft. At the same time, the angle of the air-expanding shaft is adjusted by adjusting the distance between the storage plates 30, so that drilling operations are performed at different angles on the outside of the air-expanding shaft.
