Abstract
Description
Technical Field
[0001] This utility model relates to the field of tube forming technology, and in particular to a wheelchair seat tube punching device. Background Technology
[0002] The wheelchair seat post is the core load-bearing component in a wheelchair seating system that connects the seat cushion frame to the main body support of the wheelchair. Its main functions are to support the user's weight, adjust the seat height and angle, and transmit sitting pressure, directly affecting the comfort, stability, and posture of the wheelchair.
[0003] In practical applications of punching equipment, wheelchair seat tubes are mostly made of steel tubing. Punching them is a crucial processing step in wheelchair production. On one hand, the seat tube needs to be fitted with the wheelchair cushion through specific holes. Typically, a row of mounting holes is punched along the same generatrix to accommodate different installation positions of the cushion and ensure its secure fixation. On the other hand, the seat tube also needs to connect to other frame components such as the wheelchair's X-shaped support tubes, requiring connecting holes punched in corresponding directions to ensure the overall stability of the wheelchair frame. However, in existing punching equipment, the wheelchair seat tube material is in a state of being fixed in the middle under stress, with no protection at either end. Once the punching machine is started, the unpunched end is in an unrestrained, suspended state. During punching, the impact force of the punch is transmitted through the tubing. The unfixed end, lacking restraint, is easily lifted and vibrates due to the impact force, and the lifted material can easily bump into the operator. Utility Model Content
[0004] The purpose of this invention is to provide a wheelchair seat tube punching device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheelchair seat post punching device, comprising a base, characterized in that: it further comprises: A support arm is fixedly connected to one side of the base, and a hydraulic punch is fixedly connected to one side of the support arm.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] Please see Figures 1-6 As shown, a wheelchair seat post punching device includes a base 1, and further includes: A support arm 2 is fixedly connected to one side of the base 1. A hydraulic punch 3 is fixedly connected to one side of the support arm 2. A worktable 4 is fixedly connected to one side of the base 1. A fixing mechanism 5 is set on the top of the workbench 4. The fixing mechanism 5 includes a rectangular plate 501 fixedly connected to one side of the workbench 4, a slider 502 slidably connected to one side of the rectangular plate 501, an arc plate 503 fixedly connected to one side of the slider 502, a support rod 504 fixedly connected to one side of the arc plate 503, and a movable mechanism 6 fixedly connected to one side of the workbench 4.
[0020] The movable mechanism 6 includes a base 601 fixedly connected to one side of the workbench 4. A screw 602 is movably connected to one side of the base 601 via a thread. A turntable 603 is fixedly connected to one side of the screw 602. A horizontal plate 604 is movably connected to the other side of the screw 602 through the base 601 via a bearing. One side of the horizontal plate 604 is fixedly connected to one side of the support rod 504. A feeding mechanism 7 is fixedly connected to one side of the support arm 2.
[0021] It should be noted that, through the setting of the movable mechanism 6, the turntable 603 can be manually rotated clockwise. The rotation of the turntable 603 drives the screw 602 to rotate synchronously. The rotation of the screw 602, in conjunction with the internal thread of the base 601, achieves the function of screwing in and out. When the screw 602 is screwed in, it drives the horizontal plate 604 to move accordingly. The movement of the horizontal plate 604 drives the support rod 504 and the arc plate 503 to move synchronously. The movement of the arc plate 503 drives the slider 502 to move horizontally along the rectangular plate 501. Finally, the two arc plates 503 move closer to each other to clamp and fix the material in the middle. At the same time, the arc plate 503 is adjusted progressively by the screw 602, which can effectively adapt to materials of different sizes and specifications, and achieve the same function of fitting and fixing.
[0022] The feeding mechanism 7 includes an L-shaped plate 701. An L-shaped plate 701 is fixedly connected to one side of the support arm 2. A bearing sleeve 702 is fixedly connected to one side of the L-shaped plate 701. A lead screw 703 is movably connected to one side of the bearing sleeve 702. A bearing plate 704 is fixedly connected to one side of the worktable 4. One side of the lead screw 703 passes through the bearing plate 704 and is movably connected to a mating plate 705 by a thread. A handle 706 is fixedly connected to one side of the lead screw 703. A fixing column 707 is fixedly connected to one side of both the bearing plate 704 and the mating plate 705. A frame 708 is fixedly connected to one side of the fixing column 707. A roller 709 is movably connected to the inner side of the frame 708 by a bearing. A belt 710 is sleeved on the surface of the roller 709. One end of the belt 710 away from the roller 709 is sleeved on the surface of the other roller 709. A drive mechanism 8 is fixedly connected to one side of the worktable 4.
[0023] It should be noted that the feeding mechanism 7 allows the wheelchair seat tube material to move to the inside of the frame 708. At this time, the belt 710 rotates, driving the roller 709 to rotate synchronously. As the belt 710 rotates, it rubs against the wheelchair seat tube material for conveying, thus saving the physical effort of manual feeding. It can also be adjusted to accommodate materials of different sizes. At this time, the handle 706 is manually rotated clockwise. The rotation of the handle 706 drives the lead screw 703 to rotate inside the bearing sleeve 702. During the rotation of the lead screw 703, the connecting plate 705 is screwed in through the thread. The connecting plate 705 moves stably along the surface of the lead screw 703, thereby adjusting the gap between it and the bearing plate 704. This allows the frame 708 and the belt 710 to have or reduce the gap to accommodate materials of different sizes for conveying.
[0024] The drive mechanism 8 includes a connecting frame 801 fixedly connected to one side of the support plate 704 and the docking plate 705. A servo motor 802 is fixedly connected to one end of the connecting frame 801 away from the support plate 704 and the docking plate 705. A pulley 803 is fixedly connected to the output end of the servo motor 802. The roller 709 and the belt 710 are connected by transmission through the pulley 803.
[0025] It should be noted that: through the setting of the drive mechanism 8, the servo motor 802 can work to drive the pulley 803 to rotate clockwise. The rotation of the pulley 803 drives the belt 710 to rotate around the roller 709. At this time, the belt 710, together with the driving force of the servo motor 802, drives the wheelchair seat tube material to be conveyed, so as to achieve the function of unloading.
[0026] A feeding plate 9 is fixedly connected to one side of both the bearing plate 704 and the docking plate 705, and a groove is provided on the surface of the feeding plate 9.
[0027] It should be noted that the setting of the feeding plate 9 can assist the workbench 4 in its work and also play a guiding role, avoiding the labor of manual feeding. Secondly, the groove on the surface of the feeding plate 9 can restrict the material of the wheelchair seat tube in the feeding plate 9, preventing the material from falling off during the falling process.
[0028] Specifically, a material transport vehicle 10 is placed on one side of the base 1, and four casters 11 are fixedly connected to the bottom corners of the material transport vehicle 10.
[0029] It should be noted that: with the setting of the material transport cart 10, the material transport cart 10 can be manually pushed to move to one side of the base 1 with the universal wheels 11, and then the punched material can be placed vertically in the material transport cart 10, so as to facilitate the user to transfer the material.
[0030] The inner cavity of the material transport vehicle 10 is horizontally fixedly connected to a material tray 12, and the surface of the material tray 12 has holes.
[0031] It should be noted that the material tray 12 can assist the material transport vehicle 10 in its work and also serve as an isolation and separation mechanism, preventing materials from piling up inside the material transport vehicle 10 and becoming difficult to retrieve.
[0032] A rubber pad 13 is fixedly connected to one side of the arc plate 503, and the rubber pad 13 is used in conjunction with the arc plate 503.
[0033] It should be noted that the rubber pad 13 assists the curved plate 503 in its operation and also provides protection, preventing the curved plate 503 from directly contacting the wheelchair seat tube material and causing scratches and wear.
[0034] A slide rail 14 is provided on the surface of the rectangular plate 501 at the position corresponding to the slider 502. The slide rail 14 is used in conjunction with the slider 502.
[0035] It should be noted that the slide rail 14 assists the slider 502 in its operation and also serves as a limit switch, preventing the slider 502 from deviating during its movement.
[0036] One side of the surface of turntable 603 is fixedly connected with anti-slip protrusions 15. There are several anti-slip protrusions 15, which are evenly distributed.
[0037] It should be noted that the anti-slip protrusions 15 assist the turntable 603 in its operation and increase frictional resistance, thus preventing the turntable 603 from slipping or becoming loose during manual rotation.
[0038] Working principle: First, the user places the wheelchair seat post on the surface of the workbench 4. Then, the user rotates the turntable 603 clockwise. The rotation of the turntable 603 drives the screw 602 to rotate. The rotation of the screw 602, in conjunction with the internal threads of the base 601, achieves the screw-in action. The screw 602 drives the horizontal plate 604 and the support rod 504 to move synchronously. The movement of the support rod 504 drives the arc plate 503 to move accordingly. The movement of the arc plate 503 drives the slider 502 to move accordingly. The slider 502, in conjunction with the slide rail 14, maintains a horizontal and stable movement on the surface of the rectangular plate 501. Finally, the two curved plates 503 approach each other to clamp and fix the wheelchair seat tube material at the middle end. After the end of the material is fixed, the hydraulic punch 3 is activated to punch holes in the material. After punching, the curved plates 503 are released, and the turntable 603 is rotated in the opposite direction, so that the screw 602, the cross plate 604, the support rod 504, and the curved plates 503 return to their initial positions. Then, the material is manually pushed into the inner side of the frame 708. At this time, the servo motor 802 is activated, and the servo motor 802 drives the pulley 8 03. Rotating clockwise causes the pulley 803 to rotate, driving the belt 710 to rotate as well. The belt 710 rotates around the roller 709. During the rotation of the belt 710, one side is in close contact with the material, thus the material is conveyed by the friction of the belt 710. This can also be adjusted to accommodate materials of different sizes. At this time, manually rotating the handle 706 clockwise causes the screw 703 to rotate inside the bearing sleeve 702. During the rotation of the screw 703, the mating plate 705 is screwed in through the thread. The mating plate 705 moves along the screw 709. The surface of 03 moves stably, thereby adjusting the gap between it and the bearing plate 704. This allows the frame 708 and the belt 710 to have or reduce the gap to accommodate materials of different sizes for conveying. When the material passes through the belt 710 and falls into the discharge plate 9, the discharge plate 9, in conjunction with the groove, allows the material to fall stably into the transport vehicle 10. Then, the material is manually stood up vertically and inserted into the hole corresponding to the material tray 12 for discharge and classification. Finally, the transport vehicle 10 is pushed to move as a whole in conjunction with the casters 11, thereby transferring the material for the next process.
