Description

Technical Field

[0001] This utility model belongs to the field of CNC machining technology, and specifically relates to a feeding device for a gantry machining center. Background Technology

[0002] With the rapid development of gantry machining center technology, automated feeding devices have become one of the core components for improving production efficiency. In the field of bar stock processing, traditional feeding equipment typically uses hoppers to hold batches of bars and relies on lifting mechanisms, guide slots, or robotic arms to feed individual bars sequentially.

[0003] When operators pour a large amount of bar stock (especially slender cylindrical bars) into the hopper, due to gravity and the friction between the bars, some bars will accumulate in a crisscrossing, overlapping, or side-by-side manner. This disordered arrangement can cause the feeding mechanism to simultaneously pick up two or more bars and bring them into the processing channel during the grabbing or pushing process. Once this overloading occurs, the gantry machining center's detection system will trigger an alarm and stop the machine. Operators must then manually put the excess bars back into the hopper. This process not only increases the frequency of manual intervention but also leads to longer processing cycles, energy waste, and accelerated equipment wear due to frequent start-ups and shutdowns. Utility Model Content

[0004] In view of the problem that when operators pour a large amount of bar stock into the hopper, some of the bar stock will be piled up in a cross, stacked or side by side, and this disordered arrangement will cause the feeding mechanism to simultaneously carry two or more bar stock into the processing channel during the grabbing or pushing process, this utility model proposes a feeding device for gantry machining centers to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a feeding device for a gantry machining center, comprising a support frame, a hopper fixedly connected to the top of the support frame, a material-stabilizing component and a linkage component respectively disposed on the outer surface of the hopper, a lifting component disposed on the side of the support frame, and a feeding component disposed on the side of the hopper. The material-stabilizing component is used to prevent the bar stock from stacking. The linkage component is used to drive the material-stabilizing component to move simultaneously from both sides. The lifting component is used to move the material upward to the feeding component. The feeding component is used to push the bar stock into the gantry machining center.

[0007] Furthermore, the material preparation assembly includes a motor, with a screw fixedly connected to the output shaft end of the motor. A groove is provided on the outer surface of the hopper, and the screw is rotatably connected inside the groove. A material preparation plate is threadedly connected to the outer surface of the screw, and the material preparation plate is slidably connected to the groove and the hopper. A support column is fixedly connected to the bottom of the motor. There are two sets of screws, and the two sets of screws are connected by a linkage assembly.

[0008] Furthermore, the linkage component includes a first synchronous pulley, the outer surface of which is fitted with a synchronous belt, and a second synchronous pulley is connected to the first synchronous pulley via the synchronous belt drive. The first and second synchronous pulleys are respectively fixedly connected to two sets of screws.

[0009] Furthermore, the lifting assembly includes an electric push rod, the fixed end of which is fixedly connected to a bracket, the movable end of which is fixedly mounted with a lifting plate, and the bottom of which is fixedly connected to a baffle.

[0010] Furthermore, the feeding assembly includes a roller shaft, which is rotatably connected to the hopper. A side plate is rotatably connected to the end of the roller shaft. A slide rail is fixedly connected to the outer surface of the side plate. An electric slider is slidably connected to the outer surface of the slide rail. A feeding frame is fixedly installed on the outer surface of the electric slider. There are multiple sets of roller shafts, and all sets of roller shafts are rotatably connected to the hopper and the side plate.

[0011] Furthermore, a support leg is fixedly installed at the bottom of the side plate, and there are multiple sets of support legs.

[0012] Furthermore, the movable end of the electric push rod is fixedly connected to a connecting plate, and the outer surface of the connecting plate is threaded with bolts. The connecting plate is fixedly connected to the lifting plate by bolts.

[0013] This utility model has the following beneficial effects:

[0014] This invention connects the hopper and the material preparation component. After the bar stock is poured into the hopper, the material preparation component is activated. The material preparation component moves along the hopper. During the movement, the material preparation component contacts the stacked bar stock in the hopper and pushes the stacked bar stock to spread out in the hopper, thus avoiding the situation where multiple sets of bar stock are fed at the same time due to accumulation.

[0015] This invention connects the screw to the first synchronous pulley. When the motor drives one set of screws to rotate, the screw drives the first synchronous pulley to rotate. The first synchronous pulley drives the second synchronous pulley to rotate via a synchronous belt. The second synchronous pulley drives the other set of screws to rotate. The two sets of screws drive the entire material plate from both sides simultaneously, making the movement of the entire material plate more stable.

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a feeding device for a gantry machining center, including a support 1. A hopper 2 is fixedly connected to the top of the support 1. A material-stabilizing component 3 and a linkage component 4 are respectively provided on the outer surface of the hopper 2. A lifting component 5 is provided on the side of the support 1, and a feeding component 6 is provided on the side of the hopper 2. The material-stabilizing component 3 is used to prevent the bar stock from stacking. The linkage component 4 is used to drive the material-stabilizing component 3 to move simultaneously from both sides. The lifting component 5 is used to move the material upward to the feeding component 6. The feeding component 6 is used to push the bar stock into the gantry machining center.

[0030] After the bar stock is poured into the hopper 2, the material straightening assembly 3 is started. The linkage assembly 4 drives the material straightening assembly 3 from both sides simultaneously, so that the material straightening assembly 3 moves in the hopper 2. During the movement, the material straightening assembly 3 can spread out the stacked bar stock to avoid multiple sets of bar stock being fed at the same time. Then, the lifting assembly 5 is started to push one of the bar stock up and let it fall onto the feeding assembly 6. After the feeding assembly 6 is started, the feeding assembly 6 can push the bar stock to move into the gantry machining center.

[0031] This utility model connects the hopper 2 and the material straightening component 3. After the bar stock is poured into the hopper 2, the material straightening component 3 is activated. The material straightening component 3 moves along the hopper 2. During the movement, the material straightening component 3 contacts the bar stock stacked in the hopper 2 and pushes the stacked bar stock to spread it out in the hopper 2, thus avoiding the situation where multiple sets of bar stock are fed at the same time due to accumulation.

[0032] In one embodiment, the material forming assembly 3 includes a motor 301, with a screw 302 fixedly connected to the output shaft of the motor 301. A groove 303 is provided on the outer surface of the hopper 2, and the screw 302 is rotatably connected inside the groove 303. A material forming plate 304 is threadedly connected to the outer surface of the screw 302. The material forming plate 304 is slidably connected to the groove 303 and the hopper 2. A support column 305 is fixedly connected to the bottom of the motor 301. There are two sets of screws 302, and the two sets of screws 302 are connected by a linkage assembly 4.

[0033] When the motor 301 is started, the output shaft of the motor 301 drives the screw 302 to rotate. The rotation trend of the material plate 304 on the screw 302 is blocked by the slide groove 303. At this time, the screw 302 can drive the material plate 304 to move along the slide groove 303. During the movement, the material plate 304 contacts the stacked bar material in the hopper 2, which can push the stacked bar material to move and spread it out in the hopper 2.

[0034] In one embodiment, the linkage component 4 includes a first synchronous pulley 401, a synchronous belt 402 is mounted on the outer surface of the first synchronous pulley 401, and a second synchronous pulley 403 is connected to the first synchronous pulley 401 via the synchronous belt 402. The first synchronous pulley 401 and the second synchronous pulley 403 are respectively fixedly connected to two sets of screws 302.

[0035] When the motor 301 drives one set of screws 302 to rotate, the first synchronous pulley 401 on the screw 302 rotates accordingly. The first synchronous pulley 401 drives the second synchronous pulley 403 to rotate synchronously through the synchronous belt 402. At this time, the second synchronous pulley 403 can drive the other set of screws 302 to rotate, so that the two sets of screws 302 simultaneously drive the material plate 304 to slide.

[0036] In one embodiment, the lifting assembly 5 includes an electric push rod 501, the fixed end of which is fixedly connected to the bracket 1, and the movable end of which is fixedly mounted with a lifting plate 502. The bottom of the lifting plate 502 is fixedly connected with a baffle 503.

[0037] When the electric push rod 501 is activated, the movable end of the electric push rod 501 extends and pushes the lifting plate 502 upward. The bar material on the lifting plate 502 is pushed up and moves diagonally upward along the hopper 2. After the baffle 503 at the bottom of the lifting plate 502 is raised, it can block the bar material in the hopper 2 and prevent the bar material from falling out of the hopper 2.

[0038] In one embodiment, the feeding assembly 6 includes a roller 601 rotatably connected to the hopper 2. A side plate 602 is rotatably connected to the end of the roller 601. A slide rail 603 is fixedly connected to the outer surface of the side plate 602. An electric slider 604 is slidably connected to the outer surface of the slide rail 603. A feeding frame 605 is fixedly installed on the outer surface of the electric slider 604. There are multiple sets of rollers 601, and all sets of rollers 601 are rotatably connected to the hopper 2 and the side plate 602.

[0039] After the lifting plate 502 pushes the bar stock up and places it above the roller 601, the electric slider 604 is activated. The electric slider 604 drives the feeding frame 605 to move along the slide rail 603. When the feeding frame 605 contacts the bar stock, it can push the bar stock to move into the gantry machining center. During the movement, the roller 601 can rotate under the bar stock, thereby reducing the friction force when the bar stock moves.

[0040] In one embodiment, for the side plate 602, a support leg 7 is fixedly installed at the bottom of the side plate 602, and there are multiple sets of support legs 7.

[0041] In one embodiment, for the electric push rod 501, the movable end of the electric push rod 501 is fixedly connected to a connecting plate 8, and the outer surface of the connecting plate 8 is threaded with a bolt 9. The connecting plate 8 is fixedly connected to the lifting plate 502 by the bolt 9.

[0042] The electric push rod 501 is fixed to the bracket 1 and the support leg 7 is fixed to the side plate 602 by connecting plate 8 and bolt 9. Bolt 9 ensures that the connection is firm and reliable while facilitating disassembly.

[0043] In summary, with the help of the above-mentioned technical solution of this utility model, after the bar stock is poured into the hopper 2, the motor 301 is started. The output shaft of the motor 301 drives the screw 302 to rotate, and the first synchronous pulley 401 on the screw 302 rotates accordingly. The first synchronous pulley 401 drives the second synchronous pulley 403 to rotate synchronously through the synchronous belt 402. At this time, the second synchronous pulley 403 can drive another set of screws 302 to rotate. The rotation trend of the material plate 304 on the screw 302 is blocked by the sliding groove 303. At this time, the two sets of screws 302 simultaneously drive the material plate 304 to slide. During the movement, the material plate 304 contacts the bar stock stacked in the hopper 2, which can push the bar stock. The stacked bars are moved to spread out in the hopper 2. The electric push rod 501 is activated, and the movable end of the electric push rod 501 extends and pushes the lifting plate 502 upward. The bars on the lifting plate 502 are pushed up and move diagonally upward along the hopper 2. After the baffle 503 at the bottom of the lifting plate 502 is raised, it can block the bars in the hopper 2 to prevent the bars from falling out of the hopper 2. After the lifting plate 502 pushes the bars up, it makes them fall above the roller 601. The electric slider 604 is activated, and the electric slider 604 drives the feeding frame 605 to move along the slide rail 603. When the feeding frame 605 contacts the bars, it can push the bars to move into the gantry machining center.

[0044] Through the above technical solution, 1. By connecting the hopper 2 and the material straightening assembly 3, after the bar stock is poured into the hopper 2, the material straightening assembly 3 is started. The material straightening assembly 3 moves along the hopper 2. During the movement, the material straightening assembly 3 contacts the bar stock stacked in the hopper 2 and pushes the stacked bar stock to spread it out in the hopper 2, avoiding the situation where multiple sets of bar stock are fed at the same time due to accumulation; 2. By connecting the screw 302 and the first synchronous wheel 401, when the motor 301 drives one set of screws 302 to rotate, the screw 302 drives the first synchronous wheel 401 to rotate. The first synchronous wheel 401 drives the second synchronous wheel 403 to rotate through the synchronous belt 402. The second synchronous wheel 403 drives the other set of screws 302 to rotate. The two sets of screws 302 drive the material straightening plate 304 from both sides at the same time, making the movement of the material straightening plate 304 more stable.
