Description

Technical Field

[0001] This invention relates to the field of fiber processing, specifically to a variable diameter fiber punching and positioning device. Background Technology

[0002] Fiber conduit is a type of tubing made from fiber materials. There are many types of fiber materials, including carbon fiber, glass fiber, ceramic fiber, and asphalt fiber. It performs well in terms of temperature resistance and insulation, and is mainly used for electrical conduit, conveying pipelines, etc.

[0003] An existing patent (publication number: CN105818202A) discloses a hole-drilling auxiliary device for fiberglass tubes, comprising a sealing sleeve coaxially arranged with the fiberglass tube and detachably clamped to the outside of the fiberglass tube, the sleeve having a through-hole in its wall for avoiding a drilling tool; a sealing element disposed on the sealing sleeve at both ends; and a connecting part connected to the sealing sleeve and communicating with the opening. Before drilling the fiberglass tube, the sealing sleeve is first fitted onto the outside of the fiberglass tube, and further sealed by the sealing element to ensure the sealing of the pre-drilled area. When the drilling tool passes through the opening to drill a hole in the fiberglass tube, the pressure oil overflowing after drilling is effectively sealed by the sealing sleeve, thereby preventing pressure oil from spraying out and causing safety hazards. The hole-drilling auxiliary device of this invention can drill holes in normally functioning fiberglass tubes. In the process of realizing this invention, the inventors discovered that at least the following problems in the prior art have not been solved: when performing ring-shaped punching operations on existing fiber tubes, it is impossible to adjust the punching interval according to the diameter of the fiber tube, which leads to the processing being more cumbersome and complicated when punching different fiber tubes, and it is not possible to effectively fix and limit fiber tubes of different diameters.

The connecting rod is snapped into the rotary locking rod. An annular groove is provided on the connecting rod. An adjusting electric cylinder is installed on the fixed frame. The telescopic end of the adjusting electric cylinder is connected to an adjusting frame. The adjusting frame is rotatably engaged with the annular groove on the connecting rod.

[0007] Preferably, a plurality of positioning components are provided, each of which is connected to a movable rod. Each positioning component includes a pusher frame fixedly connected to the movable rod. A housing is slidably disposed on the inner side wall of the mounting frame. The housing is hollow. The outer wall of the housing is fixedly connected to the pusher frame. A measuring frame is slidably disposed inside the housing. The end of the measuring frame faces the opening. A measuring groove is provided on the mounting frame. A measuring rod is provided on the measuring frame and slides with the measuring groove. Elastic blocks are provided at both ends of the measuring rod. The elastic blocks engage with the measuring groove. A connecting spring connects the measuring frame and the pusher frame. A positioning block is fixedly connected to the end of the measuring frame facing the opening. An unfolding plate is hinged to the opposite sides of the positioning block. A pusher plate is disposed opposite to the outer wall of the housing. The end of the pusher plate facing the positioning block is hinged with the unfolding plate.

[0008] Preferably, the driving device includes a drive motor fixedly connected to the top of the support platform, the main shaft of the drive motor is driven by a drive helical gear, and the outer wall of the mounting frame is provided with a transmission helical gear that meshes with the drive helical gear.

[0009] Preferably, the drilling device includes a rotating rod rotatably mounted on the outer wall of a support frame, a gearbox mounted on the rotating rod, a transmission rod rotatably mounted on the support frame, a rotating helical gear fixedly mounted on the transmission rod, the rotating helical gear meshing with a transmission helical gear, a transmission disc fixedly mounted on the transmission rod, a transmission groove formed on the rotating rod, a transmission belt sleeved between the transmission disc and the transmission groove, a rotating frame rotatably mounted on the support frame, the rotating rod being fixedly connected to one of the rotating frames, a movable frame eccentrically mounted between the two rotating frames, a pressure block slidably mounted on the support frame above the support plate, a drill bit mounted on the bottom of the pressure block facing the support plate, a connecting frame hinged to the pressure block, and the end of the connecting frame away from the pressure block being hinged to the movable frame.

[0010] Preferably, the support frame is further provided with an arc-shaped limiting groove, an adjusting block is slidably disposed in the arc-shaped limiting groove, an adjusting plate is hingedly disposed on the adjusting block, and the adjusting plate is hingedly engaged with the movable frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when punching holes in the fiber tube, one end of the fiber tube is inserted into the opening on one side of the mounting frame. The height of the support plate is adjusted so that the support plate supports the bottom of the fiber tube. The adjusting frame is moved under the drive of the adjusting electric cylinder. The connecting rod and the rotating clamping rod are engaged through the annular groove on the connecting rod. Then, the rotating clamping rod is driven to rotate by the rotary motor. The rotation of the rotating clamping rod drives the connecting rod to rotate, which in turn causes the adjusting plate to rotate. Several arc-shaped grooves on the adjusting plate cause the engaging rod to move the moving rod toward the opening. Thus, the rotation of the adjusting plate can synchronously control several moving rods to move toward the fiber tube placed at the opening, thereby enabling several positioning components to position and clamp the fiber tube around the opening.

[0012] In this invention, when the moving rod moves toward the opening, it drives the sleeve to move toward the fiber tube at the opening via the push frame. Under the force of the connecting spring, the measuring frame moves synchronously toward the opening. After the measuring frame contacts the outer wall of the fiber tube, it stops moving. The diameter of the fiber tube is determined by the position of the measuring rod on the measuring frame in the measuring groove, which facilitates the subsequent drilling operation of the fiber tube. At the same time, the measuring frame is limited by the elastic locking block on the measuring rod engaging with the measuring groove. After the measuring frame stops moving, the sleeve continues to move toward the fiber tube under the continuous movement of the push frame. After the sleeve moves, the unfolding plates on both sides of the positioning block will expand and contract toward the fiber tube under the action of the push plate, thereby fixing the outer wall of the fiber tube. The positioning block and the two unfolding plates provide three-point positioning, improving the stability of the fiber tube fixation.

[0013] In this invention, when performing annular drilling on the fiber tube, the position of the measuring rod is first observed, and then the gearbox is adjusted. As the mounting frame rotates, the helical gear drives the rotating gear to rotate via the transmission helical gear. The rotating gear then rotates the transmission rod, which in turn drives the rotating frame to rotate via the transmission belt. This rotating frame then drives the eccentrically positioned moving frame to rotate, which in turn pulls the connecting frame back and forth, causing the pressure block at the other end of the connecting frame to move towards the fiber tube. The drilling tool on the pressure block drills holes in the fiber tube. The position of the measuring rod is observed, and the diameter of the fiber tube is observed. Adjusting the gearbox changes the speed of the rotating rod as the mounting frame rotates, allowing for adaptive adjustment during annular drilling based on the fiber tube's diameter. An arc-shaped limiting groove allows the adjusting block to move within it. This movement pulls the adjusting plate, which in turn pulls the moving frame, adjusting the distance the pressure block moves on the support frame, thus adjusting the drilling depth of the fiber tube.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 9 This invention provides a technical solution: a variable diameter fiber punching and positioning device, including a processing table 1, a lead screw slide 11 is provided on the top of the processing table 1, a support platform 12 is connected to the lead screw slide 11, the support platform 12 is slidably engaged with the top of the processing table 1, a mounting frame 13 is rotatably mounted on the support platform 12, the mounting frame 13 is rotatably engaged with the support platform 12, an opening 14 for placing fiber tubes is provided on the mounting frame 13, a positioning auxiliary device 2 is provided inside the mounting frame 13, a positioning component 3 is connected to the positioning auxiliary device 2, and a driving device 4 is provided on the top of the support platform 12 that is in transmission engagement with the mounting frame 13.

[0018] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning auxiliary device 2 includes an adjusting plate 21 disposed on the outer wall of the mounting frame 13 away from the opening 14. The adjusting plate 21 is screwed into the mounting frame 13. The outer wall of the adjusting plate 21 has several arc-shaped grooves 22 around its circumference. Several moving rods 23 corresponding to the arc-shaped grooves 22 are disposed on the outer wall of the mounting frame 13 around its circumference. The moving rods 23 are slidably engaged with the mounting frame 13 and are oriented towards the opening 14. A locking rod 24 extends from the moving rod 23 towards the arc-shaped groove 22 and is located in the arc-shaped groove 22. A support frame 25 is also fixedly connected to the top of the support platform 12. A support plate 26 is slidably disposed longitudinally on the support frame 25. A punching device 5 is disposed on the top of the support frame 25. When punching the fiber tube... When drilling, insert one end of the fiber tube into the opening 14 on one side of the mounting bracket 13. Adjust the height of the support plate 26 so that the support plate 26 supports the bottom of the fiber tube. Driven by the adjusting electric cylinder 212, the adjusting bracket 213 moves. The connecting rod 210 is engaged with the rotating clamping rod 29 through the annular groove 211 on the connecting rod 210. Then, the rotating clamping rod 29 is rotated by the rotating motor 28. The rotation of the rotating clamping rod 29 drives the connecting rod 210 to rotate. The connecting rod 210 will cause the adjusting plate 21 to rotate. The several arc-shaped grooves 22 provided on the adjusting plate 21 will cause the clamping rod 24 to move the moving rod 23 toward the opening 14. Thus, the rotation of the adjusting plate 21 can synchronously control several moving rods 23 to move toward the fiber tube placed at the opening 14. Thus, the several positioning parts 3 can be positioned and clamped around the opening 14.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a fixed frame 27 is fixedly installed on the top of the support platform 12 next to the adjusting plate 21. A rotary motor 28 is fixedly connected to the fixed frame 27. The main shaft of the rotary motor 28 is driven by a rotary locking rod 29. A connecting rod 210 is snapped onto the adjusting plate 21 in the direction of the rotary locking rod 29. The connecting rod 210 and the rotary locking rod 29 are snapped together. An annular groove 211 is provided on the connecting rod 210. An adjusting electric cylinder 212 is provided on the fixed frame 27. An adjusting frame 213 is connected to the telescopic end of the adjusting electric cylinder 212. The adjusting frame 213 is rotatably engaged with the annular groove 211 on the connecting rod 210. The positioning element 3 is provided in several parts, and each positioning element 3 is connected to the moving rod 23. Each positioning element 3 includes a push frame 31 fixedly connected to the moving rod 23. A housing 32 is slidably disposed on the inner side wall of the mounting frame 13. The housing 32 is hollow. The outer wall of the housing 32 is fixedly connected to the push frame 31. A measuring frame 33 is slidably disposed inside the housing 32. The end of the measuring frame 33 is oriented towards the opening 14. A measuring groove 34 is provided on the mounting frame 13. A measuring rod 35 is provided, which slides with the measuring groove 34. The measuring rod 35 has elastic blocks 36 at both ends, which engage with the measuring groove 34. A connecting spring 37 connects the measuring frame 33 and the push frame 31. A positioning block 38 is fixedly connected to the end of the measuring frame 33 facing the opening 14. An unfolding plate 39 is hinged to the opposite sides of the positioning block 38. A push plate 310 is provided on the outer wall of the casing 32. The end of the push plate 310 facing the positioning block 38 is hinged to the unfolding plate 39. When the moving rod 23 moves toward the opening 14, the moving rod 23 will drive the sleeve 32 toward the fiber tube at the opening 14 through the push frame 31. Under the force of the connecting spring 37, the measuring frame 33 moves toward the opening 14 simultaneously. At this time, after the measuring frame 33 contacts the outer wall of the fiber tube, the measuring frame 33 will not continue to move. The diameter of the fiber tube is determined by the measuring rod 35 on the measuring frame 33 being in the measuring groove 34, which facilitates the subsequent drilling operation of the fiber tube. At the same time, the measuring frame 33 can be limited by the elastic locking block 36 on the measuring rod 35 engaging with the measuring groove 34. When the measuring frame 33 stops moving, the sleeve 32 will continue to move toward the fiber tube under the continuous movement of the push frame 31. After the sleeve 32 moves, under the drive of the push plate 310, the unfolding plates 39 on both sides of the positioning block 38 will unfold toward the fiber tube, thereby fixing the outer wall of the fiber tube. The positioning block 38 and the two unfolding plates 39 are used for three-point positioning to improve the stability of the fiber tube fixation.

[0020] In this embodiment, as Figure 1 and Figure 2As shown, the driving device 4 includes a driving motor 41 fixedly connected to the top of the support platform 12. The main shaft of the driving motor 41 is driven by a driving helical gear 42. The outer wall of the mounting frame 13 is provided with a transmission helical gear 43 that meshes with the driving helical gear 42. After the fiber tube is fixed, the connecting rod 210 and the rotating clamp 29 are no longer locked by the annular groove 211 on the connecting rod 210. Driven by the driving motor 41, the driving helical gear 42 rotates. The rotation of the driving helical gear 42 drives the transmission helical gear 43 to rotate, thereby enabling the mounting frame 13 to rotate on the top of the support platform 12, thereby adjusting the position of the fiber tube and enabling the fiber tube to perform annular punching operations.

[0021] In this embodiment, as Figure 1 , Figure 8 and Figure 9 As shown, the drilling device 5 includes a rotating rod 51 rotatably mounted on the outer wall of the support frame 25. A gearbox 52 is mounted on the rotating rod 51. A transmission rod 53 is also rotatably mounted on the support frame 25. A rotating helical gear 54 is fixedly mounted on the transmission rod 53, meshing with a transmission helical gear 43. A transmission disc 55 is fixedly mounted on the transmission rod 53. A transmission groove is formed on the rotating rod 51, and a transmission belt 5 is fitted between the transmission disc 55 and the transmission groove. 6. A rotating frame 57 is rotatably mounted on the support frame 25. The rotating rod 51 is fixedly connected to one of the rotating frames 57. A movable frame 58 is eccentrically mounted between the two rotating frames 57. A pressure block 59 is slidably mounted on the support frame 25 above the support plate 26. A drill bit 510 is mounted on the bottom of the pressure block 59 facing the support plate 26. A connecting frame 511 is hinged on the pressure block 59. The end of the connecting frame 511 away from the pressure block 59 is hinged to the movable frame 58. The support frame 25 is also provided with an arc-shaped limiting groove 512. An adjusting block 513 is slidably arranged in the arc-shaped limiting groove 512. An adjusting plate 514 is hinged on the adjusting block 513. The adjusting plate 514 is hinged to the movable frame 58. When performing annular drilling on the fiber tube, first observe the position of the measuring rod 35, then adjust the gearbox 52. As the mounting bracket 13 rotates, it drives the rotating helical gear 54 to rotate via the transmission helical gear 43. The rotation of the helical gear 54 causes the transmission rod 53 to rotate, which in turn drives the rotating rod 51 to rotate via the transmission belt 56. The rotation of the rotating rod 51 drives the rotating frame 57 to rotate, which in turn drives the eccentrically positioned moving frame 58 to rotate. The moving frame 58 then reciprocates, pulling the connecting frame 511 to move, thereby causing the pressure block 59 at the other end of the connecting frame 511 to move towards the fiber tube. This movement is achieved through the drill on the pressure block 59. The drilling tool 510 drills holes in the fiber tube. By observing the position of the measuring rod 35, the diameter of the fiber tube can be observed. The speed of the rotating rod 51 can be changed when the mounting frame 13 rotates, so that it can be adaptively adjusted according to the diameter of the fiber tube when making equidistant annular holes. The adjusting block 513 moves within the arc-shaped limiting groove 512. When the adjusting block 513 moves, it pulls the adjusting plate 514 to move, so that the adjusting plate 514 can pull the moving frame 58 to move, thereby adjusting the distance that the pressure block 59 moves on the support frame 25, and thus adjusting the drilling depth of the fiber tube.

[0022] The method of use and advantages of the present invention: The working process of the variable diameter fiber punching and positioning device is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown: When drilling holes in the fiber tube, one end of the fiber tube is inserted into the opening 14 on one side of the mounting bracket 13. The height of the support plate 26 is adjusted so that the support plate 26 supports the bottom of the fiber tube. Under the drive of the adjusting electric cylinder 212, the adjusting bracket 213 is moved. The connecting rod 210 is engaged with the rotating clamping rod 29 through the annular groove 211 on the connecting rod 210. Then, the rotating clamping rod 29 is rotated by the rotating motor 28. The rotation of the rotating clamping rod 29 causes the connecting rod 210 to rotate. The connecting rod 210 will cause the adjusting plate 21 to rotate. The several arc-shaped grooves 22 provided on the adjusting plate 21 will cause the clamping rod 24 to move the moving rod 23 toward the opening 14. Thus, the rotation of the adjusting plate 21 can synchronously control several moving rods 23 to move toward the fiber tube placed at the opening 14. Thus, the several positioning parts 3 can be positioned and clamped around the opening 14. When the moving rod 23 moves toward the opening 14, the moving rod 23 will drive the sleeve 32 toward the fiber tube at the opening 14 through the push frame 31. Under the force of the connecting spring 37, the measuring frame 33 moves toward the opening 14 in sync. At this time, after the measuring frame 33 contacts the outer wall of the fiber tube, the measuring frame 33 will not continue to move. The diameter of the fiber tube is determined by the measuring rod 35 on the measuring frame 33 being in the measuring groove 34, which facilitates the subsequent drilling operation of the fiber tube. At the same time, the measuring frame 33 can be limited by the elastic locking block 36 on the measuring rod 35 engaging with the measuring groove 34. When the measuring frame 33 stops moving, the sleeve 32 will continue to move toward the fiber tube under the continuous movement of the push frame 31. After the sleeve 32 moves, under the drive of the push plate 310, the unfolding plates 39 on both sides of the positioning block 38 will unfold toward the fiber tube, thereby fixing the outer wall of the fiber tube. The positioning block 38 and the two unfolding plates 39 are used for three-point positioning to improve the stability of the fiber tube fixing. When performing annular drilling on the fiber tube, first observe the position of the measuring rod 35, then adjust the gearbox 52. As the mounting bracket 13 rotates, it drives the rotating helical gear 54 to rotate via the transmission helical gear 43. The rotation of the helical gear 54 causes the transmission rod 53 to rotate, which in turn drives the rotating rod 51 to rotate via the transmission belt 56. The rotation of the rotating rod 51 drives the rotating frame 57 to rotate, which in turn drives the eccentrically positioned moving frame 58 to rotate. The moving frame 58 then reciprocates, pulling the connecting frame 511 to move, thereby causing the pressure block 59 at the other end of the connecting frame 511 to move towards the fiber tube. This movement is achieved through the drill on the pressure block 59. The drilling tool 510 drills holes in the fiber tube. By observing the position of the measuring rod 35, the diameter of the fiber tube can be observed. The speed of the rotating rod 51 can be changed when the mounting frame 13 rotates, so that it can be adaptively adjusted according to the diameter of the fiber tube when making equidistant annular holes. The adjusting block 513 moves within the arc-shaped limiting groove 512. When the adjusting block 513 moves, it pulls the adjusting plate 514 to move, so that the adjusting plate 514 can pull the moving frame 58 to move, thereby adjusting the distance that the pressure block 59 moves on the support frame 25, and thus adjusting the drilling depth of the fiber tube.
