Description

Technical Field

[0001] The invention relates to the field of central tube production, in particular to an intelligent central tube punching device. Background Art

[0002] Filtration and separation membrane modules are often used in liquid separation processes in water treatment, sewage treatment, beverages, food, pharmaceuticals, chemicals, laboratories, environmental engineering and bioengineering industries. Filtration and separation membrane modules are practical devices that include membranes and their supporting structures. Single or multiple modules can be assembled into membrane separation devices for use in factories and laboratories. The central tube is an important component in the membrane module.

[0003] During the production process of the center tube, a drilling device is required to drill multiple rows of penetration holes on the cylindrical side of the center tube. After drilling one row of penetration holes in the center tube, the center tube needs to be rotated a certain angle before continuing to drill holes. The existing center tube is prone to friction with the supporting structure of the drilling device during rotation, resulting in serious wear on the outer side of the center tube, affecting the production quality of the center tube. Summary of the invention

[0004] Therefore, it is necessary to provide an intelligent central tube punching device to solve the problem that the outer side of the central tube is easily worn in the existing punching device.

[0005] To achieve the above-mentioned purpose, the present invention provides an intelligent central tube drilling device, including a workbench, a gantry and a control cabinet; a placement frame, a rotating module and a sliding module are fixed on the workbench, the rotating module and the sliding module are respectively located on two opposite sides of the workbench, the placement frame is fixed between the rotating module and the sliding module, the placement frame includes a mounting plate and two parallel fixed rotating shafts, the fixed rotating shafts are fixed on the mounting plate, a plurality of rotating wheels are rotatably mounted on the fixed rotating shafts, the rotating wheels on the two fixed rotating shafts jointly support the central tube, the rotating module and the sliding module are used to jointly clamp the two ends of the central tube, and drilling slide rails are provided on the two side edges of the workbench parallel to the placement frame; Both ends of the gantry are slidably connected with the drilling slide rails, the drilling slide rails are provided with a horizontal sliding motor, the horizontal sliding motor is used to drive the gantry to slide back and forth along the drilling slide rails, the gantry is fixed with a vertical slide rail, the vertical slide rails are fixed with a vertical sliding motor, the vertical slide rails are slidably provided with a drilling motor, the vertical sliding motor is used to drive the drilling motor to slide back and forth along the vertical slide rails, and a drill bit is provided on the output shaft of the drilling motor; a plurality of displacement sensing probes are spaced apart on the side of the workbench along the sliding direction of the gantry, the displacement sensing probes are electrically connected to the control cabinet, and the horizontal sliding motor, the vertical sliding motor, the drilling motor, the rotating module and the sliding module are electrically connected to the control cabinet respectively.

[0006] Furthermore, a cavity is provided inside the rotating wheel, and the cavity is filled with a non-Newtonian fluid, and the filling rate of the non-Newtonian fluid in the cavity is less than 100%. The non-Newtonian fluid does not completely fill the cavity and has a certain fluidity. When the drill bit drills the central tube, the rotating wheel will receive a certain vibration impact. At this time, the viscosity of the non-Newtonian fluid is enhanced and the fluidity is reduced due to the vibration impact. The non-Newtonian fluid is in a hardened state, and the center of gravity of the entire rotating wheel is more stable, thereby avoiding relative rotation of the rotating wheel when drilling the central tube, improving the accuracy of drilling the central tube, and when the central tube is in a non-drilling state, the rotating module drives the central tube to rotate, the non-Newtonian fluid restores fluidity, and the rotating wheel will rotate relatively to avoid wearing the outer surface of the central tube.

[0007] Furthermore, the inner side surface of the cavity is provided with a plurality of bosses in the circumferential direction. The bosses increase the contact surface between the non-Newtonian fluid and the rotating wheel. When the non-Newtonian fluid is hardened by vibration impact, the non-Newtonian fluid and the rotating wheel are closely combined, which is more conducive to stabilizing the center of gravity of the rotating wheel and preventing the rotating wheel from rotating relative to each other.

[0008] Furthermore, the rotating wheel is arranged to slide along the axial direction of the fixed rotating shaft, and a buffer spring is connected between two adjacent rotating wheels. The rotating wheel does not have a fixed position on the fixed rotating shaft, and the rotating wheel can slide relatively on the fixed rotating shaft according to the vibration it receives, and the buffer spring can slow down the transmission of the vibration received by the rotating wheel in the axial direction.

[0009] Furthermore, the rotating module includes a rotating motor and a rotating fixture, the rotating fixture is fixed on the output shaft of the rotating motor, the sliding module includes a sliding cylinder, a sliding plate, a sliding rail and a clamping block, the sliding rail is fixed on the workbench, the sliding plate is slidably arranged on the sliding rail, the output shaft of the sliding cylinder is connected to the sliding plate, the clamping block is fixed on the sliding plate, the clamping block corresponds to the rotating fixture, the rotating motor, the rotating fixture and the sliding cylinder are electrically connected to the control cabinet respectively. The rotating fixture is used to clamp one end of the central tube, the clamping block slides and clamps the two ends of the central tube with the rotating fixture, and the rotating motor can drive the rotation of the central tube through the rotating fixture, thereby realizing the punching of the peripheral side of the central tube.

[0010] Furthermore, the sliding module also includes a hand-cranked drive device, which includes a spiral sleeve, a spiral rod and a hand-cranked wheel. The spiral sleeve is fixed on the sliding plate, the spiral sleeve is sleeved on the spiral rod, and the hand-cranked wheel and the clamping block are respectively fixed at both ends of the spiral rod. The hand-cranked drive device is used to manually advance or retract the clamping block. When there is a problem with the control of the sliding cylinder, the staff can turn the hand-cranked wheel to retract the spiral rod and the clamping block away from the center tube, thereby removing the center tube.

[0011] Furthermore, the clamping block is a horizontally arranged cylinder, one side of the clamping block is fixed to the spiral rod, and the other side of the clamping block is fixed with a conical clamping head. The clamping block and the clamping fixture fix and clamp the central tube, and the conical clamping head can extend into the interior of the central tube, which is convenient for positioning the central tube.

[0012] Furthermore, the mounting plate is provided with multiple pairs of support platforms at intervals, each pair of two support platforms corresponds to two fixed rotating shafts one by one, the support platforms are provided with multiple long strip mounting grooves, each pair of two support platforms corresponds to one mounting groove, the support platforms are provided with mounting holes, and the support platforms and the mounting plate are fixed by embedding bolts in the mounting holes and the mounting grooves. The relative distance of each pair of support platforms can be adjusted through the long strip mounting grooves, which is convenient for dealing with center pipes of different specifications and diameters.

[0013] Furthermore, the gantry also includes a flushing pipe with a flushing head, and the other end of the flushing pipe is connected to an external water tank. The flushing head faces the drill bit, and the drill bit is an external chip removal drill bit.

[0014] The flushing pipe is used to flush the drilling position of the center tube to prevent debris from remaining in the drill hole and affecting the drilling process. At the same time, the flushing water also has a certain cooling effect on the drill bit. The external chip removal rotor can prevent debris from drilling into the center tube, reduce subsequent cleaning steps, and improve production efficiency.

[0015] The above technical solution has the following beneficial effects:

[0016] In the present invention, the rotating wheel is used to provide sufficient supporting force for the long strip center tube to avoid the center tube from breaking while drilling. The rotating wheel can rotate with the center tube while facilitating the positioning of the center tube. When the rotating module drives the center tube to rotate a certain angle, the rotating wheel can also rotate relatively. The rotation of the rotating wheel can prevent the rotating wheel from wearing the outer surface of the center tube, thereby ensuring the yield rate of the center tube product. The displacement sensing probe is used to detect the sliding position of the gantry in real time and feed it back to the control cabinet. Thereafter, the control cabinet is used to intelligently control the entire punching device to avoid manual operation, thereby ensuring that the punching device drills holes on the center tube with high efficiency and high precision. The control cabinet is electrically controlled and connected with the horizontal sliding motor, the vertical sliding motor, the drilling motor, the rotating module and the sliding module to realize the automation of the center tube drilling process, thereby effectively improving the production efficiency of the center tube.

DETAILED DESCRIPTION

[0028] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0029] Example 1

[0030] See also Figure 1-6 , Fig. 9 This embodiment provides an intelligent central tube drilling device, including a workbench 1, a gantry 2 and a control cabinet 3.

[0031] A placement rack 4, a rotating module 5 and a sliding module 6 are fixed on the workbench 1. The placement rack 4 is fixed between the rotating module 5 and the sliding module 6. The placement rack 4 includes a mounting plate 41 and two parallel fixed rotating shafts 42. The fixed rotating shafts 42 are fixed on the mounting plate. The mounting plate 41 is fixed on the workbench 1. A plurality of rotating wheels 43 are rotatably mounted on the fixed rotating shaft 42. The rotating wheels 43 are freely slidably arranged along the axial direction of the fixed rotating shaft 42. The rotating wheels 43 on the two fixed rotating shafts 42 jointly support the central tube 9.

[0032] Specifically, multiple pairs of support platforms 45 are arranged on the mounting plate 41 at intervals, and each pair of two support platforms 45 corresponds to two fixed rotating shafts 42 one by one. Multiple long strip mounting grooves 411 are arranged on the support platforms 45, and each pair of two support platforms 45 corresponds to one mounting groove 411. The support platforms 45 are provided with mounting holes 451, and the support platforms 45 and the mounting plate 41 are fixed by bolts embedded in the mounting holes 451 and the mounting grooves 411. The relative distance between each pair of support platforms 45 can be adjusted through the long strip mounting grooves 411, so as to facilitate the handling of center tubes 9 with different specifications and diameters.

[0033] The rotating module 5 and the sliding module 6 are respectively located on two opposite sides of the workbench 1 . The rotating module 5 and the sliding module 6 are used to clamp the two ends of the central tube 9 together. Drilling slide rails 11 are provided on the two sides of the workbench 1 parallel to the placement frame 4 .

[0034] Specifically, the rotating module 5 includes a rotating motor 51 and a rotating fixture 52. The rotating fixture 52 is fixed on the output shaft of the rotating motor 51. The sliding module 6 includes a sliding cylinder 61, a sliding plate 62, a sliding rail 63 and a clamping block 64. The sliding rail 63 is fixed on the workbench 1. The sliding plate 62 is slidably arranged on the sliding rail 63. The output shaft of the sliding cylinder 61 is connected to the sliding plate 62. The clamping block 64 is fixed on the sliding plate 62. The clamping block 64 corresponds to the rotating fixture 52. The rotating fixture 52 is used to clamp one end of the central tube 9. The clamping block 64 slides with the rotating fixture 52 to clamp the two ends of the central tube 9. The rotating motor 51 can drive the central tube 9 to rotate through the rotating fixture 52, thereby realizing the punching of the peripheral side of the central tube 9. The rotating motor 51, the rotating fixture 52 and the sliding cylinder 61 are electrically connected to the control cabinet 3 respectively.

[0035] In this embodiment, the rotating module 5 may further include a reducer, and the rotating fixture 52 is drivingly connected to the rotating motor 51 via the reducer, and the rotating motor 51 is a servo motor.

[0036] The sliding module 6 also includes a hand-cranked drive device 65, which includes a spiral sleeve 651, a spiral rod 652 and a hand-cranked wheel 653. The spiral sleeve 651 is fixed on the sliding plate 62, and the spiral sleeve 651 is sleeved on the spiral rod 652. The hand-cranked wheel 653 and the clamping block 64 are respectively fixed on both ends of the spiral rod 652.

[0037] The hand-cranked drive device 65 is used to manually advance or retract the clamping block 64. When there is a problem with the control of the sliding cylinder 61, the staff turns the hand-cranked wheel 653, the screw rod 652 retracts, and the clamping block 64 moves away from the center tube 9, thereby removing the center tube 9.

[0038] The clamping block 64 is a horizontally arranged cylinder, one side of which is fixed to the screw rod 652, and a conical clamping head is fixed to the other side of the clamping block 64. The clamping block 64 and the clamping fixture fix and clamp the central tube 9, and the conical clamping head can extend into the interior of the central tube 9, which facilitates the positioning of the central tube 9.

[0039] In this embodiment, a rotating bearing 654 is fixed at the connection between the clamping block 64 and the spiral rod 652, and the clamping block 64 is fixed on the cylinder, so that when the central tube 9 rotates, the clamping block 64 can rotate at the same time.

[0040] Both ends of the gantry 2 are slidably connected with the drilling slide rail 11. The drilling slide rail 11 is provided with a horizontal sliding motor 14. The horizontal sliding motor 14 is used to drive the gantry 2 to slide back and forth along the drilling slide rail 11. The gantry 2 is fixed with a vertical slide rail 7. The vertical slide rail 7 is fixed with a vertical sliding motor 15. The vertical slide rail 7 is slidably provided with a drilling motor 71. The vertical sliding motor 15 is used to drive the drilling motor 71 to slide back and forth along the vertical slide rail 7. The output shaft of the drilling motor 71 is provided with a drill bit 72. The gantry 2 also includes a flushing pipe 21 and a flushing head 22 of the flushing pipe 21. The other end of the flushing pipe 21 is connected to an external water tank 8. The flushing head 22 faces the drill bit 72. The drill bit 72 is an external chip removal drill bit 72. The horizontal sliding motor 14, the vertical sliding motor 15, and the drilling motor 71 are electrically connected to the control cabinet 3 respectively.

[0041] The flushing pipe 21 is used to flush the drilling position of the central tube 9 to prevent debris from remaining on the drill hole and affecting the drilling process. At the same time, the flushing water also has a certain cooling effect on the drill bit 72. The external chip removal rotor can prevent debris from drilling from entering the interior of the central tube 9, reducing subsequent cleaning steps and improving production efficiency.

[0042] In this embodiment, the flushing pipe 21 is a universal bamboo tube, a protective baffle 12 is fixed to the side of the workbench 1, and a water outlet is provided on the workbench 1. The universal bamboo tube can flexibly adjust the direction of the flushing head 22, and has a certain stability, so as to avoid the shaking of the flushing pipe 21 during the left and right sliding of the gantry 2, thereby ensuring the smooth progress of drilling. The protective baffle 12 is used to prevent debris from being scattered after drilling, and the water outlet can discharge the water flushed by the flushing pipe 21.

[0043] A plurality of displacement sensing probes 13 are provided at intervals on the side of the workbench 1 along the sliding direction of the gantry 2 . The displacement sensing probes 13 are electrically connected to the control cabinet 3 . In this embodiment, the displacement sensing probes 13 are fixed to the inner side of the protective baffle 12 .

[0044] The control cabinet 3 controls the sliding of the gantry 2 and the drilling motor 71. The control cabinet 3 is used to control the opening and closing of the drilling motor 71, the rotating motor 51, the rotating fixture 52 and the sliding cylinder 61. The entire punching device is intelligently controlled by the control cabinet 3 to avoid manual operation, ensuring that the punching device can drill holes on the central tube 9 with high efficiency and high accuracy.

[0045] In this embodiment, the drilling slide rail 11 and the vertical slide rail 7 are provided with driving devices - horizontal sliding motor 14 and vertical sliding motor 15, which are used to drive the sliding of the gantry 2 and the drilling motor 71. The horizontal sliding motor 14 and the vertical sliding motor 15, the drilling motor 71, the rotating motor 51, the rotating clamp 52 and the sliding cylinder 61 are all connected to the control cabinet 3 through wires. The control console has a built-in control program and an operation interface is set on it. The staff inputs the specifications of the central tube 9 and the drilling specifications through the operation interface, and then the control program intelligently controls the opening and closing of the corresponding electrical components.

[0046] In this embodiment, there are two sets of the placing rack 4, the rotating module 5 and the sliding module 6 on the workbench 1, and there are two sets of the drilling motor 71 and the drill bit 72 on the gantry 2, so that two center tubes 9 can be processed simultaneously.

[0047] Example 2

[0048] See also Figure 7-8 This embodiment provides an intelligent central tube punching device. Compared with the embodiment 1, this embodiment further transforms the structure of the rotating wheel 43 on the basis of the embodiment 1, as follows:

[0049] The rotating wheel 43 is provided with a cavity 431 inside, and the cavity 431 is filled with a non-Newtonian fluid 432, and the filling rate of the non-Newtonian fluid 432 in the cavity 431 is less than 100%. The non-Newtonian fluid 432 does not completely fill the cavity 431, and has a certain fluidity. When the drill bit 72 drills the central tube, the rotating wheel 43 will receive a certain vibration impact. At this time, the viscosity of the non-Newtonian fluid 432 is enhanced and the fluidity is reduced due to the vibration impact. The non-Newtonian fluid 432 is in a hardened state, and the center of gravity of the entire rotating wheel 43 is more stable, thereby avoiding the relative rotation of the rotating wheel 43 when drilling the central tube, and improving the accuracy of the central tube drilling. When the central tube is in a non-drilling state, when the rotating module 5 drives the central tube to rotate, the non-Newtonian fluid 432 restores fluidity, and the rotating wheel 43 will rotate relatively to avoid wearing the outer surface of the central tube.

[0050] The filling rate of the non-Newtonian fluid 432 is 60-90%, specifically 60%, 70%, 80%, 90%. In this embodiment, the filling rate of the non-Newtonian fluid 432 is 80%.

[0051] The inner side surface of the cavity is circumferentially provided with a plurality of bosses 433. The bosses 433 increase the contact surface between the non-Newtonian fluid 432 and the rotating wheel 43. When the non-Newtonian fluid 432 is hardened by vibration impact, the non-Newtonian fluid 432 and the rotating wheel 43 are closely combined, which is more conducive to stabilizing the center of gravity of the rotating wheel 43 and preventing the rotating wheel 43 from rotating relative to each other.

[0052] In this embodiment, the cross section of the boss 433 is a trapezoid. The rotating wheel 43 is slidably arranged along the axial direction of the fixed rotating shaft 42 , and a buffer spring 44 is connected between two adjacent rotating wheels 43 .

[0053] The rotating wheel 43 does not have a fixed position on the fixed rotating shaft 42 , and the rotating wheel 43 can slide relatively on the fixed rotating shaft 42 according to the vibration it receives, and the buffer spring 44 can slow down the transmission of the vibration received by the rotating wheel 43 in the axial direction.

[0054] The steps for using the central tube 9 punching device of the present invention are as follows:

[0055] 1. The staff first sets the specifications of the central tube 9 and the specifications of the holes on the control cabinet 3, and then places the central tube 9 on the placement rack 4, the rotating wheel 43 supports the central tube 9, and one end of the central tube 9 is placed in the rotating fixture 52;

[0056] 2. The control cabinet 3 opens the entire punching device, the sliding cylinder 61 extends, pushes the clamping block 64 and the rotating clamp 52 to clamp the center tube 9, the rotating clamp 52 clamps the end of the center tube 9, and the gantry 2 moves to the end close to the sliding module 6.

[0057] 3. The control cabinet 3 controls the drilling motor 71 to move down along the vertical slide rail 7 through the vertical sliding motor 15, the drilling motor 71 is turned on, the drill bit 72 drills a hole on the central tube 9, and the flushing head 22 is turned on while drilling to flush the drilled hole. After the drilling is completed, the drilling motor 71 moves up along the vertical slide rail 7, and the control cabinet 3 controls the gantry 2 to move to the next drilling position through the horizontal sliding motor 14, and repeats this step;

[0058] 4. After a row of holes is punched on the central tube 9, the control cabinet 3 controls the rotating motor 51 to drive the central tube 9 to rotate a certain angle through the rotating fixture 52, and then stops, and the gantry 2 moves to one end close to the sliding module 6, and repeats step 3;

[0059] 5. When the center tube 9 is completed with drilling, the control cabinet 3 controls the sliding cylinder 61 to retract, the clamping block 64 and the rotating fixture 52 release the center tube 9, the rotating fixture 52 releases the end of the center tube 9, the staff takes out the center tube 9 with the completed drilling, continues to put in the center tube 9 to be drilled, and repeats the above steps.

[0060] In the present invention, the rotating wheel 43 is used to provide sufficient supporting force for the long strip center tube 9 to prevent the center tube 9 from breaking while drilling. The rotating wheel 43 can rotate with the center tube 9 while facilitating the positioning of the center tube 9. When the rotating module 5 drives the center tube 9 to rotate a certain angle, the rotating wheel 43 can also rotate relatively. The rotation of the rotating wheel 43 can prevent the rotating wheel 43 from wearing the outer surface of the center tube 9, thereby ensuring the yield rate of the center tube 9 product.
