Description

Technical Field

[0001] The utility model relates to the technical field of part processing, and particularly relates to a feeding device for processing turning profiled parts of a bullet train. Background Art

[0002] Turning profiled parts of a bullet train are key components for supporting, positioning, and guiding during the turning process of a bullet train. They are usually precisely machined and specially designed to ensure the stability and safety of the bullet train during high-speed turning. These profiled parts may include, but are not limited to, certain structural parts on the bogie, suspension system components, and specific parts of the car body frame;

[0003] When a factory processes turning profiled parts, after the workpiece to be processed is usually conveyed by a conveying mechanism, it is grabbed by a material grabbing robot and then moved into a processing machine for processing;

[0004] As in the prior art, a Chinese patent with the authorization announcement number CN211282712U discloses a feeding device for processing turning profiled parts of a bullet train. By setting a positioning and loading mechanism, since the material receiving groove faces the second guide plate, the workpiece will directly slide into the material receiving groove. The transported workpieces can be collected and positioned by a material receiving block, and then the material receiving block is driven by a hydraulic cylinder to move upward. Since the bottom of the material receiving groove is provided with an inclined surface, it can effectively prevent the workpiece from falling out of the material receiving groove during the movement. Since the moving position of the material receiving block is fixed, the grabbing efficiency of the material grabbing robot can be effectively improved. Compared with the prior art, it can position and convey the workpiece, improving the conveying efficiency:

[0005] However, this device cannot ensure that the workpiece is in the center of the conveyor belt during the conveying process of the workpiece, resulting in the situation that when the workpiece enters the material receiving groove in the material receiving block, the position of the workpiece may shift inward or outward, leading to the situation that the material grabbing robot cannot accurately grab. Therefore, a feeding device for processing turning profiled parts of a bullet train is designed to solve the above problems. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide a feeding device for processing turning profiled parts of a bullet train, which solves the problem that the conveying component in the prior art cannot prevent the workpiece from shifting inward or outward in the material receiving groove, resulting in the situation that the material grabbing robot cannot accurately grab.

[0008] The utility model provides a feeding device for processing the turning profiled parts of multiple units, which includes a feeding belt conveyor. A feeding plate is fixedly arranged on the left side of the feeding belt conveyor. A material guiding groove is formed on the upper surface of the feeding plate. Multiple sets of deviation rectifying components are installed on both the inner and outer sides of the upper surface of the feeding belt conveyor. A guiding plate is fixedly arranged on the right side of the feeding belt conveyor. A positioning base plate is fixedly arranged on the supporting leg on the right side of the feeding belt conveyor. An electric telescopic rod is fixedly installed at the bottom of the positioning base plate. A receiving box is fixedly arranged at the output end of the electric telescopic rod;

[0009] The deviation rectifying component includes a fixed shaft, a rotating plate, a fixed disk and a torsion spring. The fixed shaft is fixedly arranged on the frame of the feeding belt conveyor. A rotating plate is rotatably arranged below the fixed shaft. A fixed disk is fixedly arranged at the top of the fixed shaft.

[0011] Preferably, when the torsion spring on the deviation rectifying component is in an untwisted state, the rotating plates all extend towards the center of the feeding belt conveyor.

[0012] Preferably, the rotating plates on the outer deviation rectifying components and the corresponding rotating plates on the inner deviation rectifying components are in an inverted "V" shape with a larger distance on the left side and a smaller distance on the right side.

[0013] Preferably, the guiding plate is in an inclined shape with a higher horizontal height on the left side and a lower horizontal height on the right side, and the horizontal height of the left side of the guiding plate is not higher than the horizontal height of the belt inside the feeding belt conveyor.

[0014] Preferably, the receiving box has a box structure with an opening on the left side, and the bottom of the receiving box is in an inclined shape with a higher horizontal height on the left side and a lower horizontal height on the right side.

[0015] Preferably, when the electric telescopic rod contracts to the minimum length, the horizontal height of the left side of the bottom of the receiving box is equal to the horizontal height of the right side of the guiding plate.

[0016] Preferably, adjusting screws are threadedly connected to the inner and outer surfaces of the receiving box, and limiting plates are rotatably arranged at the ends of the adjusting screws through bearings.

During the process of the feeding belt conveyor conveying the workpiece, when the workpiece contacts the rotating plate on the deviation rectifying component, the rotating plate rotates along the fixed shaft, and the torsion spring is in a torsion state.

According to the width of the workpiece, the distance between the two limiting plates is adjusted so that the distance between the two limiting plates is equal to the width of the workpiece, and it is ensured that the distance between the limiting plates and the inner side surface of the receiving box is the same. Since the left side of the limiting plate 702 is in a trapezoidal state with a decreasing thickness component, during the process of the workpiece moving to the right when entering the receiving box, the limiting plate can rectify the deviation of the workpiece again, ensuring that the workpiece is in the center position of the receiving box, and further facilitating the accurate grasping of the material grabbing robot.

[0030] Embodiment:

[0031] As Figures 1 - 5 shown, an embodiment of the present utility model provides a feeding device for processing turning press parts of a multiple unit train, including a feeding belt conveyor 1. A loading plate 2 is fixedly arranged on the left side of the feeding belt conveyor 1. A material guiding groove 201 is formed on the upper surface of the loading plate 2. A plurality of deviation rectifying components are installed on both the inner and outer sides of the upper surface of the feeding belt conveyor 1. A material guiding plate 4 is fixedly arranged on the right side of the feeding belt conveyor 1. A positioning base plate 5 is fixedly arranged on the right support leg of the feeding belt conveyor 1. An electric telescopic rod 6 is fixedly installed at the bottom of the positioning base plate 5. The output end of the electric telescopic rod 6 is fixedly provided with a material receiving box 7;

[0032] The deviation rectifying component includes a fixed shaft 3, a rotating plate 301, a fixed disk 302 and a torsion spring 303. The fixed shaft 3 is fixedly arranged on the frame of the feeding belt conveyor 1. A rotating plate 301 is rotatably arranged below the fixed shaft 3. A fixed disk 302 is fixedly arranged at the top of the fixed shaft 3. A torsion spring 303 is fixedly arranged between the fixed disk 302 and the rotating plate 301.

[0033] During the actual use process, the workpiece to be processed is placed in the material guiding groove 201. Under the action of the gravity of the workpiece, the workpiece slides onto the feeding belt conveyor 1. The workpiece is conveyed to the right by the feeding belt conveyor 1. After the workpiece moves to the material guiding plate 4, it enters the material receiving box 7 for collection. The electric telescopic rod 6 extends to drive the material receiving box 7 to move upward. When the material receiving box 7 moves to a suitable position, it cooperates with another grasping robot for grasping.

[0034] By providing a deviation rectifying component, during the process of the feeding belt conveyor conveying the workpiece, when the workpiece contacts the rotating plate 301 on the deviation rectifying component, the rotating plate 301 rotates along the fixed shaft 3, and the torsion spring 303 is in a torsion state. The restoring force of the torsion spring 303 can make the rotating plate 301 drive the workpiece to move towards the central direction of the feeding belt conveyor 1, so as to ensure that during the process of the feeding belt conveyor 1 feeding the workpiece, the workpiece is in the center of the feeding belt conveyor, ensure that when the workpiece moves into the material receiving box 7, the workpiece is in the center of the material receiving box 7, and ensure the accurate grasping of the grasping robot.

[0035] In this embodiment, the material guiding groove 201 is inclined with a higher horizontal height on the left side and a lower horizontal height on the right side, and the horizontal height of the right end of the material guiding groove 201 is not higher than the horizontal height of the feeding belt in the feeding belt conveyor 1, which facilitates the workpiece to slide to the right side of the feeding belt conveyor 1 under the action of gravity.

[0036] In this embodiment, when the torsion springs 303 on the deviation rectifying components are in an untwisted state, the rotating plates 301 all extend towards the center of the feeding belt conveyor 1.

[0037] In this embodiment, the rotating plates 301 on the outer deviation rectifying components and the corresponding rotating plates 301 on the inner deviation rectifying components are in an inverted "V" shape with a larger distance on the left side and a smaller distance on the right side, which facilitates the rotating plates 301 to deflect the workpieces conveyed by the feeding belt conveyor 1 to the exact center of the feeding belt conveyor 1.

[0038] In this embodiment, the guide plate 4 is inclined with a higher horizontal height on the left side and a lower horizontal height on the right side, and the horizontal height of the left side of the guide plate 4 is not higher than the horizontal height of the belt in the feeding belt conveyor 1, ensuring that the feeding belt conveyor 1 conveys the workpieces onto the guide plate 4.

[0039] In this embodiment, the receiving box 7 has a box structure with an opening on the left side, and the bottom of the receiving box 7 is inclined with a higher horizontal height on the left side and a lower horizontal height on the right side, preventing the workpieces in the receiving box 7 from falling out of the left opening during the lifting process of the receiving box 7.

[0040] In this embodiment, when the electric telescopic rod 6 contracts to the minimum length, the horizontal height of the left side of the bottom of the receiving box 7 is equal to the horizontal height of the right side of the guide plate 4, facilitating the receiving box 7 to collect the workpieces poured out by the guide plate 4.

[0041] In this embodiment, adjusting screws 701 are threadedly connected to the inner and outer surfaces of the receiving box 7, and limiting plates 702 are rotatably arranged at the ends of the adjusting screws 701 through bearings.

[0042] In this embodiment, the limiting plates 702 are attached to the inner bottom of the receiving box 7, and the limiting plates 702 are trapezoidal with a gradually decreasing thickness on the left side, and the left sides of the two limiting plates 702 are in an inverted "V" shape.

[0043] By providing the limiting plates 702, the distance between the two limiting plates 702 is adjusted according to the width of the workpiece, so that the distance between the two limiting plates 702 is equal to the width of the workpiece, and it is ensured that the distances between the limiting plates 702 and the inner side surfaces of the receiving box 7 are the same. Since the left sides of the limiting plates 702 are in a trapezoidal state with a gradually decreasing thickness, during the process of the workpiece moving to the right side when entering the receiving box 7, the limiting plates 702 can further rectify the deviation of the workpiece, ensuring that the workpiece is at the exact center position of the receiving box 7, and further facilitating the accurate grasping of the material grabbing robot.

[0044] In this embodiment, a reinforcing rod 501 is connected between the bottom surface of the positioning substrate 5 and the support leg of the feeding belt conveyor 1, which increases the stability of the positioning substrate 5 fixed on the feeding belt conveyor 1.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
