Description

Technical Field

[0001] This utility model relates to the field of long shaft machining technology, specifically to an intermittent feeding mechanism for long shaft machining. Background Technology

[0002] In the processing and production of column and bar profiles, the material loading process is a crucial step. Currently, many companies still use the relatively traditional manual loading method for column and bar profiles. This method is not only inefficient but also labor-intensive, easily leading to worker fatigue and potentially causing safety accidents.

[0003] Although some companies have adopted automated feeding equipment, such as bar stock pusher feeders, which use pushers to push bar stock onto the conveyor belt, there is a technical problem: the pusher may push more than one bar stock. When more than one bar stock is pushed to the conveyor, the conveyor will transport multiple bar stock into the processing section, causing multiple bar stock to accumulate and not be processed evenly. This gradually paralyzes the processing section, requiring manual observation and cleaning to maintain normal operation. Utility Model Content

[0004] The purpose of this invention is to provide an intermittent feeding mechanism for long shaft machining to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intermittent feeding mechanism for long shaft machining, comprising a feeding bin, wherein a push plate that slides vertically is provided in the feeding area of ​​the feeding bin, and a cover plate arranged parallel to the bottom surface of the inner cavity of the feeding bin is detachably connected to the loading area of ​​the feeding bin, and a mounting seat is detachably connected to the cover plate, wherein a rotating shaft is fixedly connected in the mounting seat, and a V-shaped lever is rotatably provided outside the rotating shaft by a torsion spring, wherein one end of the V-shaped lever near the bottom surface of the inner cavity of the feeding bin abuts against the bottom surface of the inner cavity of the feeding bin.

[0006] Furthermore, the top of the feeding hopper is fixedly connected to an inclined plate arranged at an angle, and the push plate is stepped, with the top of the push plate inclined towards the direction of the inclined plate arrangement.

[0007] Furthermore, a threaded sleeve is connected to one end of the V-shaped lever near the bottom of the inner cavity of the feeding hopper via a bearing, and a stop bar is connected to the threaded sleeve.

[0008] Furthermore, the cover plate has a through groove, and multiple screw holes are equally spaced on both sides of the through groove. The mounting base is installed by screwing screws into the screw holes.

[0009] Furthermore, the side of the feeding hopper has multiple equally spaced through holes in the vertical direction, and the cover plate is fixed by screws passing through the through holes and being screwed into the cover plate.

[0010] Furthermore, the bottom of the push plate is fixedly connected to the movable end of a cylinder, and the cylinder is installed on the feeding hopper.

[0011] In the above technical solution, the intermittent feeding mechanism for long shaft machining provided by this utility model has the following beneficial effects:

[0012] This invention, by setting a cover plate, allows the bar stock to be laid flat on the bottom surface of the inner cavity of the feeding bin. With the positioning of the V-shaped lever, the gap between the V-shaped lever and the push plate can only hold one bar stock at a time. This allows the push plate to push one bar stock at a time into the transportation section and then to the processing section, making the bar stock processing more precise and the bar stock processing production line run more smoothly.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Please see Figures 1-4 An intermittent feeding mechanism for long shaft machining includes a feeding bin 1. A push plate 31 that slides vertically is provided in the feeding area of ​​the feeding bin 1. A cover plate 2 arranged parallel to the bottom surface of the inner cavity of the feeding bin 1 is detachably connected to the loading area of ​​the feeding bin 1. A mounting base 4 is detachably connected to the cover plate 2. A rotating shaft 41 is fixedly connected inside the mounting base 4. A V-shaped lever 5 is rotatably provided outside the rotating shaft 41 through a torsion spring 6. The torsion spring 6 is sleeved on the outside of the rotating shaft 41. One end of the torsion spring 6 is inserted into the V-shaped lever 5, and the other end is inserted into the mounting base 4 to provide torque force to the V-shaped lever 5. The end of the V-shaped lever 5 near the bottom surface of the inner cavity of the feeding bin 1 abuts against the bottom surface of the inner cavity of the feeding bin 1.

[0025] This utility model, by setting a cover plate 2, allows the bar stock to be laid flat on the bottom surface of the inner cavity of the feeding bin 1. With the position of the V-shaped lever 5, the gap between the V-shaped lever 5 and the push plate 31 can only hold one bar stock. This allows the push plate 31 to push one bar stock at a time into the transportation section and then to the processing section, making the bar stock processing more precise and the bar stock processing production line run more smoothly.

[0026] Furthermore, an inclined plate 11 is fixedly connected to the top of the feeding hopper 1. The push plate 31 is stepped, and the top of the push plate 31 is inclined towards the inclined plate 11. A screw sleeve 8 is connected to the end of the V-shaped lever 5 near the bottom of the inner cavity of the feeding hopper 1 through a bearing 7. The outer wall of the bearing 7 is fixedly connected to the screw sleeve 8, and the inner wall of the bearing 7 is fixedly fitted inside the V-shaped lever 5. The V-shaped lever 5 is a V-shaped plate, and the end of it without the screw sleeve 8 near the push plate 31 is rounded. A stop rod 9 is threadedly connected to the screw sleeve 8. An arc groove is opened on the bottom of the stop rod 9 away from the push plate 31, so that the bottom of the stop rod 9 forms a hook shape. By rotating the screw sleeve 8, the screw sleeve 8 rotates in place under the limiting action of the bearing 7, so that the stop rod 9 is in the axis of the screw sleeve 8. The length of the stop bar 9 extending from the screw sleeve 8 is adjusted by moving it upwards. A through groove 21 is provided on the cover plate 2, and multiple screw holes 22 are equally spaced on both sides of the through groove 21. The mounting base 4 is installed by screwing it into the screw holes 22. By fixing the mounting base 4 at the positions of different screw holes 22, the distance between the V-shaped lever 5 and the push plate 31 is changed, thereby adapting to different sizes of bar stock. Multiple through holes 12 are arranged equally spaced on the side of the feeding bin 1 in the vertical direction. The cover plate 2 is fixed by screwing it into the cover plate 2 through the through holes 12. The vertical distance between the cover plate 2 and the bottom surface of the inner cavity of the feeding bin 1 is adjusted, and then the cover plate 2 is installed by screwing it through the corresponding through holes 12, thereby adapting to different sizes of bar stock.

[0027] Specifically, depending on the size of the bar stock, the vertical distance between the bottom surface of the cover plate 2 and the bottom surface of the inner cavity of the feeding bin 1 is adjusted. Similarly, the position of the mounting base 4 on the cover plate 2 needs to be adjusted so that only one bar stock can be accommodated between the V-shaped lever 5 and the push plate 31. At the same time, since the distance between the bottom surface of the cover plate 2 and the bottom surface of the feeding bin 1 has changed, the length of the stop rod 9 extending out of the screw sleeve 8 needs to be adjusted so that the bottom of the stop rod 9 can abut against the bottom of the inner cavity of the feeding bin 1, and then continue to feed the new size bar stock in a single intermittent manner.

[0028] Furthermore, the bottom of the push plate 31 is fixedly connected to the movable end of the cylinder 3, and the cylinder 3 is installed on the feeding bin 1.

[0029] In this utility model, reference Figures 1 to 3Along the inclined surface of the inner cavity of the feeding bin 1, the bar stock rolls sequentially between the cover plate 2 and the bottom surface of the inner cavity of the feeding bin 1. As the cylinder 3 drives the push plate 31 to push the first bar stock upward, the push plate 31 pushes the V-shaped lever 5 to rotate counterclockwise against the torque force of the torsion spring 6, so that the stop bar 9 no longer obstructs the bar stock. The bar stock moves down along the inclined surface, so that the second bar stock enters the preparation area between the V-shaped lever 5 and the push plate 31. After the push plate 31 is reset, the V-shaped lever 5 loses the pushing force of the push plate 31. Under the action of the torque force of the torsion spring 6, the V-shaped lever 5 rotates clockwise, pushing the subsequent bar stock to roll upward along the inclined surface, continuing the next intermittent feeding cycle.

[0030] In this utility model, the amount of bar material fed between the cover plate 2 and the feeding bin 1 each time needs to be such that the torsion spring 6 can push it to roll upward along the inclined surface of the inner cavity of the feeding bin 1. That is, the larger the size of the bar material, the smaller the total amount of bar material placed between the cover plate 2 and the bottom surface of the inner cavity of the feeding bin 1.

[0031] refer to Figure 5 The device is a slender shaft bar machining machine. The bar stock is fed to the transportation department via the intermittent feeding device, and the transportation department feeds the bar stock one by one into the... Figure 5 The material is processed at the feed inlet of the machining center.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
