Description

Technical Field

[0001] This utility model relates to the field of tent pole processing, and specifically discloses a high-efficiency grooving machine for tent poles. Background Technology

[0002] Tents are a core piece of equipment for modern outdoor activities, balancing lightweight design with functionality to provide users with a safe and comfortable temporary shelter. Mainstream tents employ modular structures, such as the wind-resistant dome type, the space-efficient tunnel type, and the ultra-lightweight pyramid type, suitable for diverse scenarios such as mountaineering, hiking, and family camping. Tent poles are the "skeleton" of the tent, providing support; their performance directly determines the overall stability and wind resistance. During the manufacturing process of tent poles, to reduce weight, arrayed weight-reducing grooves are created on the poles.

[0003] In existing technologies, the machining of weight-reducing grooves on tent poles typically employs a combination of clamping and CNC milling. Specifically, after the poles are clamped and fixed in place by a clamp, a CNC milling machine controls a milling cutter to perform the grooving operation.

[0004] However, since tent poles are typically long, and the milling cutter stroke of a CNC milling machine is limited, machining portions exceeding the stroke requires multiple adjustments to the pole position and reclamping. This repetitive operation significantly reduces machining efficiency. Furthermore, during adjustments, it's difficult to ensure the poles don't deflect, making it challenging to maintain a strictly straight alignment for the subsequent weight-reducing grooves, leading to disordered groove distribution. Therefore, a high-efficiency grooving machine for tent poles is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a high-efficiency grooving machine for tent poles, which can efficiently groove poles without requiring multiple clamping operations; it also prevents poles from deflecting due to multiple adjustments, thereby ensuring the straightness of the grooving.

[0006] This utility model is implemented as follows: a high-efficiency grooving machine for tent poles includes a base plate, poles, and a grooving mechanism. A vertical plate is installed on the upper end of the base plate, and a movable plate is slidably connected to the upper end of the base plate via a slide rail. A driving mechanism is provided on the right side of the vertical plate. The driving mechanism includes an end plate installed on the upper end of the base plate. A lead screw that is threadedly connected to the movable plate is rotatably connected between the end plate and the vertical plate. A servo motor with its output end fixedly connected to the lead screw is installed on the outer wall of the end plate.

[0007] A U-shaped plate is installed at the upper end of the movable plate. A clamping mechanism is provided inside the U-shaped plate. The clamping mechanism includes a fixed clamping seat installed inside the U-shaped plate. A screw is rotatably connected to the upper end of the inner wall of the U-shaped plate. A threaded cylinder is threadedly connected to the outer wall of the screw. An installation cover is installed at the lower end of the threaded cylinder. A pressure plate is provided inside the installation cover. A pressure sensor that abuts against the pressure plate is installed at the top of the inside of the installation cover. A connecting plate is installed at the lower end of the pressure plate. A movable clamping seat is installed at the lower end of the connecting plate. Grooves are provided on opposite sides of both the fixed clamping seat and the movable clamping seat.

[0008] A drive mechanism is provided on the upper side of the screw;

[0009] A positioning cylinder is fixedly connected to the outer wall of the upright plate, and the rod passes through the inside of the positioning cylinder and abuts between two grooves.

[0010] As a preferred embodiment of the present invention, the high-efficiency grooving machine for tent poles includes a grooving mechanism comprising a box body slidably connected to the left side of the upright plate via a slide groove and a slider. A turntable is rotatably connected to the lower end of the box body. A drive motor with its output end fixedly connected to the turntable is installed inside the box body. A milling cutter located above the pole is installed at the lower end of the turntable. A fixing plate is fixedly connected to the left end of the upright plate. An electric push rod with its output end fixedly connected to the box body is installed at the upper end of the fixing plate.

[0011] As a preferred embodiment of the present invention, the high-efficiency grooving machine for tent poles includes a drive mechanism comprising a drive frame mounted on the upper end of a U-shaped plate, a worm gear rotatably connected inside the drive frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the screw, a stepper motor whose output end is fixedly connected to the worm gear mounted on the outer wall of the drive frame, a controller mounted on the left end of the drive frame, a pressure sensor electrically connected to the controller, and the controller electrically connected to the stepper motor.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A high-efficiency grooving machine for tent poles includes a base plate 1, poles 28 and a grooving mechanism. A vertical plate 2 is installed on the upper end of the base plate 1. A movable plate 10 is slidably connected to the upper end of the base plate 1 via a slide rail. A driving mechanism is provided on the right side of the vertical plate 2. The driving mechanism includes an end plate 12 installed on the upper end of the base plate 1. A lead screw 11 threadedly connected to the movable plate 10 is rotatably connected between the end plate 12 and the vertical plate 2. A servo motor 13 with its output end fixedly connected to the lead screw 11 is installed on the outer wall of the end plate 12.

[0028] A U-shaped plate 14 is installed on the upper end of the movable plate 10. A clamping mechanism is provided inside the U-shaped plate 14. The clamping mechanism includes a fixed clamping seat 15 installed inside the U-shaped plate 14. A screw 17 is rotatably connected to the upper end of the inner wall of the U-shaped plate 14. A threaded cylinder 18 is threadedly connected to the outer wall of the screw 17. An installation cover 19 is installed at the lower end of the threaded cylinder 18. A pressure plate 20 is provided inside the installation cover 19. A pressure sensor 21 that abuts against the pressure plate 20 is installed at the top of the installation cover 19. A connecting plate 22 is installed at the lower end of the pressure plate 20. A movable clamping seat 16 is installed at the lower end of the connecting plate 22. Grooves 27 are provided on opposite sides of the fixed clamping seat 15 and the movable clamping seat 16.

[0029] A drive mechanism is provided on the upper side of the screw 17;

[0030] A positioning cylinder 3 is fixedly connected through the outer wall of the upright plate 2, and the rod 28 passes through the interior of the positioning cylinder 3 and abuts between the two grooves 27.

[0031] In this embodiment: During use, the rod 28 is inserted into the positioning cylinder 3, and the end of the rod 28 extends between the groove 27 of the fixed clamping seat 15 and the movable clamping seat 16. Then, the drive mechanism drives the screw 17 to rotate, causing the threaded cylinder 18 to press down on the mounting cover 19, pushing the movable clamping seat 16 closer to the fixed clamping seat 15. The rod 28 is clamped by the arc structure of the groove 27. The pressure sensor 21 monitors the pressure of the pressure plate 20 in real time. When the pressure reaches the preset value, the screw 17 stops rotating, and the rod 28 is clamped to prevent the rod 28 from moving.

[0032] The servo motor 13 drives the lead screw 11 to rotate, causing the moving plate 10 to move horizontally to the left along the slide rail. This allows the rod 28, which is clamped in the groove 27, to be axially fed relative to the milling cutter 8. Simultaneously, the grooving mechanism mills and grooves the surface of the rod 28. The inner diameter of the positioning cylinder 3 matches the diameter of the rod 28, providing axial positioning when the rod 28 moves horizontally, ensuring the coaxiality of the grooving section and the clamping section. When the length of the groove is appropriate, the servo motor 13 drives the moving plate 10 to move to the preset stroke (corresponding to the length of a single groove). The electric push rod 5 pulls the milling cutter 8 to rise and reset. The servo motor 13 controls the moving plate 10 to feed step by step according to the preset program. After each groove is processed, the moving plate 10 automatically moves to the next groove, realizing continuous processing of multiple grooves. The rod 28 does not need to be disassembled throughout the process, improving work efficiency.

[0033] In the above process, since it is not necessary to repeatedly clamp the rod 28 and the clamping effect is stable, the rod 28 is prevented from deflecting due to multiple adjustments, thereby improving the straightness of the slot.

[0034] It should be noted that the servo motor 13 uses an absolute encoder model E6CP-A with a positioning accuracy of +8.81mm, while the pressure sensor (21) is selected from the MISENSOR brand MF01 series with a range of 0-500N and an accuracy of 8.5%FS.

[0035] As a technical optimization of this utility model, the grooving mechanism includes a box 6 slidably connected to the left side of the upright plate 2 via a sliding groove and a slider. A turntable 7 is rotatably connected to the lower end of the box 6. A drive motor 9 with its output end fixedly connected to the turntable 7 is installed inside the box 6. A milling cutter 8 located above the rod 28 is installed at the lower end of the turntable 7. A fixing plate 4 is fixedly connected to the left end of the upright plate 2. An electric push rod 5 with its output end fixedly connected to the box 6 is installed at the upper end of the fixing plate 4.

[0036] In this embodiment: the electric actuator 5 pushes the housing 6 to move up and down along the slide groove of the vertical plate 2, adjusting the cutting depth of the milling cutter 8.

[0037] The drive motor 9 drives the turntable 7 and the milling cutter 8 to rotate at high speed, and mills and grooves the surface of the rod 28.

[0038] As a technical optimization of this utility model, the driving mechanism includes a driving frame 23 mounted on the upper end of the U-shaped plate 14. A worm gear 24 is rotatably connected inside the driving frame 23. A worm wheel 25 is meshed with the outer wall of the worm gear 24. A transmission shaft is fixedly connected between the worm wheel 25 and the screw 17. A stepper motor 26 with its output end fixedly connected to the worm gear 24 is mounted on the outer wall of the driving frame 23. A controller is mounted on the left end of the driving frame 23. A pressure sensor 21 is electrically connected to the controller. The controller is electrically connected to the stepper motor 26.

[0039] In this embodiment: the stepper motor 26 drives the worm 24 to rotate, which in turn drives the worm wheel 25 and the transmission shaft to rotate, ultimately driving the screw 17 to rotate. The worm wheel 25 and the worm 24 transmission have self-locking characteristics to ensure stable clamping.

[0040] The pressure sensor 21 monitors the clamping force in real time. When the preset value is reached, the controller stops the stepper motor 26.

[0041] As a technical optimization of this utility model, the movable clamping seat 16 is slidably connected to the inside of the U-shaped plate 14 through two sliding grooves and two sliders.

[0042] In this embodiment, the slide groove restricts the movable clamping seat 16 to move only in the vertical direction, thus preventing skewing during the clamping process.

[0043] As a technical optimization of this utility model, the pressure plate 20 is slidably connected to the inside of the mounting cover 19 through two sliding grooves and two sliders.

[0044] In this embodiment, the sliding groove constrains the pressure plate 20 to move only up and down, thus preventing uneven pressure distribution caused by rotation or tilting of the pressure plate 20.

[0045] As a technical optimization of this utility model, both grooves 27 are arc-shaped structures that are adapted to the outer wall of the rod 28, and anti-slip textures are provided inside both grooves 27.

[0046] In this embodiment: the arc surface fits against the outer wall of the rod 28, and the anti-slip texture increases friction to prevent the rod 28 from sliding during processing.

[0047] As a technical optimization of this utility model, the left side of the inner wall of the positioning cylinder 3 is set as a flared structure.

[0048] In this embodiment: the flared structure guide rod 28 is quickly inserted and aligned with the central axis of the positioning cylinder 3.

[0049] The working principle and usage process of this utility model are as follows: When in use, the rod 28 is inserted into the flared end of the positioning cylinder 3. The flared structure guides the rod 28 to quickly center and position. After the rod 28 passes through the positioning cylinder 3, its end extends to the groove 27 between the fixed clamping seat 15 and the movable clamping seat 16. Then, the stepper motor 26 drives the worm gear 24 and worm wheel 25 to drive the screw 17 to rotate, causing the threaded cylinder 18 to press down on the mounting cover 19 and push the movable clamping seat 16 closer to the fixed clamping seat 15. The rod 28 is clamped by the arc structure of the groove 27. The pressure sensor 21 monitors the pressure of the pressure plate 20 in real time. When the pressure reaches the preset value, the controller automatically stops the stepper motor 26. At this time, the rod 28 is clamped to prevent the rod 28 from moving.

[0050] Then, the servo motor 13 drives the lead screw 11 to rotate, causing the moving plate 10 to move horizontally to the left along the slide rail. This allows the rod 28, clamped in the groove 27, to be axially fed relative to the milling cutter 8. Simultaneously, the electric push rod 5 pushes the housing 6 down along the slide groove of the vertical plate 2. The drive motor 9 drives the turntable 7 and the milling cutter 8 to rotate at high speed, causing the milling cutter 8 to cut into the rod 28. As the milling cutter 8 feeds, it mills and grooves the surface of the rod 28. The diameter of the milling cutter 8 corresponds to the width of the groove, while the inner diameter of the positioning cylinder 3 corresponds to the diameter of the rod 28. Matching, the servo motor 13 provides axial positioning when the rod 28 moves horizontally, ensuring the coaxiality of the slotted section and the clamping section. When the length of the slot is appropriate, the servo motor 13 drives the moving plate 10 to move to the preset stroke (corresponding to the length of a single slot). Then, the electric push rod 5 pulls the milling cutter 8 to rise and reset. The servo motor 13 controls the moving plate 10 to feed step by step according to the preset program. After each slot is processed, the moving plate 10 automatically moves to the next slot, realizing continuous processing of multiple slots. The rod 28 does not need to be disassembled throughout the process, which improves work efficiency.

[0051] In the above process, since it is not necessary to repeatedly clamp the rod 28 and the clamping effect is stable, the rod 28 is prevented from deflecting due to multiple adjustments, thereby improving the straightness of the slot.
