Description

Technical Field

[0001] This utility model relates to a cutting auxiliary device, specifically a pneumatic automatic feeding mechanism. Background Technology

[0002] Currently, the rear axle tubing for electric tricycles is manually sawn after being positioned using tooling. This process is labor-intensive, inefficient, and prone to defects such as slanted cuts and inconsistent lengths. It fails to guarantee consistent product quality and creates difficulties for subsequent welding.

[0003] Currently, a utility model patent with publication number CN210125765U discloses a multi-station steel pipe cutting equipment. This equipment includes a cutting worktable, a support frame, a feeding device, a cutting device, and a PLC controller. The feeding device comprises a front feeding platform, a middle feeding platform, and a rear feeding platform. Each feeding platform is equipped with a multi-station conveying roller of uniform specifications. The movement of the conveying rollers is controlled by the PLC controller to achieve the conveying action of the steel pipe. A steel pipe sorting baffle is also provided between the middle and rear feeding platforms. Through this method, the present invention can achieve automated control of the cutting process, and the cutting speed is increased several times compared to commonly used cutting devices, significantly improving production efficiency, reducing manual labor hours in the cutting process, and achieving the goal of cost reduction and efficiency improvement.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN210125765U can realize the automated control of the cutting process, and the cutting speed is increased by several times compared with commonly used cutting devices, which significantly improves production efficiency, reduces the manual labor time of the cutting process, and achieves the purpose of cost reduction and efficiency improvement. However, this patent is essentially a newly designed steel pipe cutting device. Although it can cut quickly, replacing this device requires the elimination of a large number of existing cutting devices, which is costly. At the same time, the device still requires manual placement of steel pipes and feeding, which will affect its production rhythm and is not very convenient to use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a pneumatic automatic feeding mechanism that can be seamlessly integrated into existing production lines at a low cost. It can automate pipe feeding and cutting, effectively control the quality of pipe cutting, and effectively improve work efficiency and reduce the labor intensity of workers.

[0006] To achieve the above objectives, this utility model provides a pneumatic automatic feeding mechanism, comprising a frame, a steel pipe, a pipe placement rack, and a pneumatic saw. A clamping mechanism is mounted on the upper part of the frame via a sliding mechanism. A downward-pressing cylinder controls the opening and closing of the clamping mechanism. One end of a sliding cylinder is hinged to the upper part of the frame, and the other end of the sliding cylinder is hinged to the clamping mechanism. A control box is fixedly mounted on the upper part of the frame. The control box is connected to multiple solenoid valves via wires. The solenoid valves are connected to a pressure regulating filter valve via pipelines. The downward-pressing cylinder and the sliding cylinder are each connected to their respective solenoid valves via pipelines. The lower end of a support mechanism is hinged to the frame, and the middle part of the support mechanism is movably connected to the frame via a hydraulic spring. The feeding end of the frame is aligned with the pipe placement rack.

[0007] In addition, the pneumatic automatic feeding mechanism proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the clamping mechanism includes upper and lower clamping plates. The lower clamping plate is mounted on the base via a slide rail and a guide rod, and the upper clamping plate is fixedly mounted on the base. The base is movably mounted on the slide rail of the sliding mechanism via a slider.

[0009] As a further improvement of this utility model, the top of the hosting mechanism is provided with rubber rollers.

[0010] As a further improvement of this utility model, the pipe placement rack is tilted to one side.

[0011] As a further improvement of this utility model, the bottom of the frame is provided with a leveling foot.

[0012] By means of the above solution, this utility model has at least the following advantages: Compared with conventional manual feeding, by using compressed air as power and PLC programming control, a clamping mechanism is used to clamp the steel pipe with the assistance of a person, and then the pipe is fed forward into the pneumatic saw at a set length and frequency to realize automated pipe sawing. This device can ensure that the feeding length is consistent each time, improve product quality consistency and production efficiency, and can be seamlessly integrated into the existing production line at a low cost. It can realize automated pipe feeding and cutting, effectively control the pipe cutting quality, and effectively improve work efficiency and reduce the labor intensity of workers.

[0016] The pneumatic automatic feeding mechanism of this utility model is described below with reference to the accompanying drawings.

[0017] In Embodiment 1 of this application, as Figure 1 and Figure 2 As shown, this pneumatic automatic feeding mechanism (hereinafter referred to as "the present invention") includes a frame 1 and a pneumatic saw 13. A clamping mechanism 3 is installed on the upper part of the frame 1 through a sliding mechanism 5. A pressing cylinder 4 controls the opening and closing of the clamping mechanism 3. One end of a sliding cylinder 7 is hinged to the upper part of the frame 1, and the other end of the sliding cylinder 7 is hinged to the clamping mechanism 3. A control box 8 is fixedly installed on the upper part of the frame 1. The control box 8 is connected to multiple solenoid valves 6 through wires. The solenoid valves 6 are connected to a pressure regulating filter valve 2 through pipelines. The pressing cylinder 4 and the sliding cylinder 7 are respectively connected to their respective solenoid valves 6 through pipelines. The lower end of the support mechanism 9 is hinged to the frame 1, and the middle part of the support mechanism 9 is movably connected to the frame 1 through a hydraulic spring 10. The feeding end of the frame 1 is aligned with the pipe placement rack 12.

[0018] A multi-station steel pipe cutting device (hereinafter referred to as "the patent") with utility model publication number CN210125765U can achieve automated control of the cutting process, and the cutting speed is increased several times compared with commonly used cutting devices, significantly improving production efficiency and reducing manual labor hours in the cutting process, thus achieving the goal of cost reduction and efficiency improvement. However, the patent is essentially a newly designed steel pipe cutting device. Although it can cut quickly, replacing this device requires the replacement of a large number of existing cutting devices, resulting in high costs. Furthermore, the device still requires manual placement and loading of steel pipes. This would affect the production rhythm and be inconvenient to use. However, this invention uses compressed air as power and PLC programming control. It uses a clamping mechanism 3 to clamp the steel pipe 11 with manual assistance, and then feeds the pipe forward into the pneumatic saw 13 at a set length and frequency to achieve automated pipe sawing. This device can ensure that the feeding length is consistent each time, improve product quality consistency and production efficiency, and can be seamlessly integrated into existing production lines at a low cost. It can realize automated pipe feeding and cutting, effectively control the pipe cutting quality, and effectively improve work efficiency and reduce the labor intensity of workers.

[0019] This embodiment 2 is basically the same as the structure of embodiment 1. The difference is that the clamping mechanism 3 includes two clamping plates, an upper clamping plate and a lower clamping plate. The lower clamping plate is mounted on the base through a slide rail and a guide rod. The upper clamping plate is fixedly mounted on the base. The base is movably mounted on the slide rail of the sliding mechanism 5 through a slider.

[0020] To further optimize the working efficiency of this application and prevent the steel pipe 11 from being scratched, the top of the support mechanism 9 is equipped with rubber rollers. To further reduce the workload and allow the steel pipe 11 to automatically roll to the clamping position of the clamping mechanism 3, the pipe placement rack 12 is tilted to one side. To make the equipment easier to level, the bottom of the frame 1 is equipped with leveling feet.

[0021] When in use, install the pneumatic automatic feeding mechanism, connect the compressed air supply pipe, and set up the pipe placement rack 12 and pneumatic saw 13 at the front and rear respectively. The equipment is then ready for use.

[0022] When this utility model is used, its specific operation is as follows:

[0023] When using, such as Figure 2 As shown, a crane is used to transport a bundle of steel pipes 11 onto the pipe placement rack 12. The binding straps of the steel pipes 11 are removed, and the steel pipes 11 are manually arranged on the pipe placement rack 12. Since the steel pipes 11 are not heavy, they can be arranged manually relatively easily. Next, the control box 8 sends a signal to the solenoid valve 6 connected to the pressing cylinder 4 through the preset program PLC module, causing it to enter the relaxed state. Then, it sends a signal to the solenoid valve 6 of the sliding cylinder 7, causing the sliding cylinder 7 to retract and drive the clamping mechanism 3 to move towards the pipe placement rack 12 under the constraint of the sliding mechanism 5. When it reaches the pipe, the worker lifts up a steel pipe 11. A pipe is inserted into the clamping mechanism 3. Then, the control box 8 outputs a signal to control the pressing cylinder 4, causing it to retract and drive the clamping mechanism 3 to press the pipe 11. Next, it outputs a signal to the sliding cylinder 7 to extend it to a preset distance. After reaching the preset distance, it sends a signal to the pneumatic chuck of the pneumatic saw 13 to clamp the pipe 11. Then, it simultaneously sends signals to the pressing cylinder solenoid valve, saw blade rotation switch, and pressing cylinder solenoid valve of the pneumatic saw. The saw blade starts to rotate and press down, while the pressing cylinder 4 enters the relaxation state to prepare to restart the program. The support mechanism 9 is used to ensure that the height of the pipe and the clamping structure are consistent.

[0024] The motion stroke and node feedback of this device are fed back to the PLC by a reed sensor installed on the outer wall of the cylinder.

[0025] In summary, the pneumatic automatic feeding mechanism of this utility model provides a more realistic tactile sensation during cardiopulmonary resuscitation (CPR) compressions by simulating pectoral muscles on a flat surface. The compression plate assembly inside the simulated chest cavity, simulating human ribs and working with the elastic support component, provides better elastic feedback and a better compression experience. Simultaneously, the pressure alarm component located between the compression plate assembly and the first spring plate triggers the alarm device when the user applies excessive pressure, causing the trigger head to move to the trigger end to remind the user to reduce the pressure and keep it within a reasonable range to avoid injury to the patient.

[0026] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
