Description

Technical Field

[0001] This application relates to the field of automation of generator claw pole production, and in particular to a generator claw pole spacing feeding device. Background Technology

[0002] The claw pole is a core component of the generator. As a major part of the rotor, it is directly responsible for establishing and rotating the magnetic field, which is the physical basis for the generator to convert mechanical energy into electrical energy.

[0003] Currently, in the turning process after the generator claw poles are die-cast, manual loading is the primary method of material feeding. During manual loading, workers need to manually pick up the die-cast claw poles and place them in the material frame, transport the material frame to the CNC machine tool, and then manually place the claw poles onto the machining fixture. This consumes a significant amount of the worker's time and energy, resulting in low work efficiency and high labor intensity. This not only affects the loading efficiency of generator claw poles but also reduces the utilization efficiency of the CNC machine tool. Utility Model Content

[0004] To improve the problem of low feeding efficiency, this application provides a generator claw pole interval feeding device.

[0005] The generator claw pole interval feeding device provided in this application adopts the following technical solution: A generator claw pole interval feeding device includes a conveying mechanism, a material channel inclinedly disposed on one side of the conveying mechanism, a blocking mechanism for guiding the generator claw poles into the material channel, a limiting mechanism disposed on the material channel, a feeding platform fixedly connected to the end of the material channel, and a flipping mechanism installed on the upper side of the feeding platform. The limiting mechanism includes a support frame fixedly connected to the upper side of the material channel, a gate plate rotatably connected to the support frame, and a limiting cylinder fixedly connected to the support frame. The piston rod of the limiting cylinder is connected to a connecting shaft. The top of the gate plate is provided with a connecting hole through which the piston rod of the limiting cylinder passes. The side wall of the gate plate is provided with a waist-shaped hole through which the connecting shaft is inserted. The connecting hole communicates with the waist-shaped hole.

[0006] By adopting the above technical solution, the generator claw poles are first horizontally conveyed by the conveying mechanism, and then diverted into the material channel by the blocking mechanism. When the piston rod of the limit cylinder extends, it drives the gate plate to rotate towards the material channel inlet, allowing the previous claw pole to pass while blocking the next one; when the piston rod of the limit cylinder retracts, it drives the gate plate to rotate towards the material channel outlet, preventing subsequent claw poles from entering the loading platform. This achieves the intermittent loading process of the generator claw poles, eliminating the need for workers to manually pick up, move, and place the claw poles on the processing fixture, reducing labor intensity and improving claw pole loading efficiency.

[0007] Optionally, the gate includes a material blocking plate, a material discharging plate, and a top cover plate. The material blocking plate is disposed on the side of the material discharging plate near the conveying mechanism, and the top cover plate is fixedly connected between the top of the material blocking plate and the top of the material discharging plate.

[0008] By adopting the above technical solution, when the piston rod of the limiting cylinder extends, it drives the gate plate to rotate, causing the feeding plate to rise to a misalignment with the generator claw pole, thereby allowing the generator claw pole to slide into the feeding platform; at the same time, the blocking plate descends to insert between the claw fingers of the next generator claw pole, causing the next generator claw pole to be obstructed and unable to slide down, thus realizing intermittent feeding.

[0009] Optionally, multiple material channels are spaced apart along the conveying direction of the conveying mechanism, and the material blocking mechanism is directly opposite the material channel.

[0010] By adopting the above technical solution, a parallel channel for synchronously conveying multiple generator claw poles is formed. The material blocking mechanism can accurately divert the generator claws into different material channels, thereby improving the feeding efficiency.

[0011] Optionally, the material blocking mechanism includes a material blocking cylinder, a blocking strip, a support block, a protrusion, and a hinge shaft. The support block is fixedly connected to one side wall of the conveying mechanism. The cylinder body of the material blocking cylinder is fixedly connected to the protrusion. The protrusion is hinged to the support block. The blocking strip has two ends, one end of which is a driving end that is hinged to the piston rod of the material blocking cylinder, and the other end is a material blocking end that extends to the upper surface of the conveying mechanism and faces the material channel. The blocking strip is hinged to the side wall of the conveying mechanism away from the material channel through the hinge shaft.

[0012] By adopting the above technical solution, the material blocking cylinder is activated, which drives the baffle bar to rotate, thereby realizing the switching between the two states of blocking and releasing the generator claw pole. This is used to control the timing of the generator claw pole entering the material channel according to the production rhythm, and to achieve diversion.

[0013] Optionally, the feeding platform includes a frame, a waiting area, a clamping area, and a support plate. The support plate is fixedly connected to one side of the frame. The waiting area and the clamping area are disposed on the platform surface of the frame. The waiting area is disposed on the side of the clamping area away from the material channel.

[0014] By adopting the above technical solution, the loading platform is divided into an independent waiting area and a gripping area. The waiting area receives the generator claw pole from the material channel, and the gripping area receives the generator claw pole after it has been flipped by the flipping mechanism, which also provides precise positioning for the subsequent gripping by the robotic arm.

[0015] Optionally, the waiting area is provided with a baffle for blocking the generator claw pole, and the gripping area is provided with a groove for limiting the generator claw pole.

[0016] By adopting the above technical solution, the baffle prevents the generator claw pole from interfering with the normal operation of the flipping mechanism due to inertial sliding, while the groove prevents the position of the generator claw pole from shifting after flipping, thus avoiding grasping failure due to claw pole displacement.

[0017] Optionally, the flipping mechanism is disposed between the waiting area and the gripping area. The flipping mechanism includes a drive cylinder, a slider, a rack, a gear, a rotating shaft, and a pneumatic gripper. The cylinder body of the drive cylinder is fixedly connected to the support plate. The piston rod and the rack of the drive cylinder are both fixedly connected to the slider. The rack and the gear mesh with each other. The rotating shaft passes through the two side walls of the frame and one end is fixedly connected to the gear. The middle part of the rotating shaft is fixedly connected to the pneumatic gripper.

[0018] By adopting the above technical solution, when the piston rod of the drive cylinder extends, it drives the slider and rack to move linearly along the extension direction of the piston rod. The rack drives the gear meshing with it to rotate, thereby driving the pneumatic gripper fixed on the same rotating shaft to rotate 180 degrees, realizing the rotation and switching of the generator gripper pole from the waiting area with the gripper fingers facing up to the gripping area with the gripper fingers facing down.

[0019] Optionally, the cross-section of the feed channel is U-shaped.

[0020] By adopting the above technical solution, a guiding channel is provided for the generator claw pole.

[0021] Optionally, the conveying mechanism includes a support frame, a conveyor belt, and a conveyor motor. The conveyor belt is mounted on the top of the support frame, and the conveyor motor is fixedly connected to one side of the support frame.

[0022] By adopting the above technical solution, the horizontal transmission of the generator claw poles can be achieved.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application realizes the automated process of generator claw pole interval feeding, and completes the entire process of generator claw pole from conveying, diverting, interval feeding and posture flipping, replacing manual picking, handling and clamping operations, and improving feeding efficiency and CNC machine tool utilization efficiency.

[0024] 2. This application achieves intermittent feeding through the coordinated operation of the limiting mechanism and the flipping mechanism. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] In related technologies, such as Figure 1 As shown, the generator claw pole includes a central yoke 100 and a plurality of claw fingers 200 arranged circumferentially along the central yoke 100.

[0034] This application discloses a generator claw pole interval feeding device.

[0035] Reference Figure 2 The generator claw pole interval feeding device includes a conveying mechanism 1, a material channel 2 inclinedly arranged on one side of the conveying mechanism 1, a blocking mechanism 3 for guiding the generator claw pole into the material channel 2, a limiting mechanism 4 arranged on the material channel 2, a feeding platform 5 fixedly connected to the end of the material channel 2, and a flipping mechanism 6 installed on the upper side of the feeding platform 5.

[0036] Reference Figure 2 , Figure 4The conveying mechanism 1 includes a support frame 11, a conveyor belt 12, and a conveyor motor 13. The conveyor belt 12 is mounted on the top of the support frame 11, and the conveyor motor 13 is fixedly connected to one side of the support frame 11 and is used to drive the conveyor belt 12. The conveyor belt 12 is a chain conveyor belt that continuously transports the generator claw poles horizontally. Other components of the conveying mechanism 1 not mentioned are prior art and will not be described in detail here.

[0037] Reference Figure 2 Multiple material channels 2 are spaced apart along the conveying direction of the conveying mechanism 1, and the material blocking mechanism 3 is directly opposite the material channel 2. The number of material channels 2 determines the number of material blocking mechanisms 3 required. In this embodiment, there are 2 material channels 2, so the corresponding number of material blocking mechanisms 3 is 2.

[0038] Reference Figure 2 , Figure 5 The cross-section of the material channel 2 is U-shaped. The upper end of the material channel 2 is fixedly connected to one side wall of the support 11, and the lower end of the material channel 2 is fixedly connected to the feeding platform 5.

[0039] Reference Figure 3 , Figure 4 The material blocking mechanism 3 includes a material blocking cylinder 31, a blocking strip 32, a support block 33, a protrusion 34, and a hinge shaft 35. The cylinder body of the material blocking cylinder 31 is fixedly connected to the protrusion 34. The support block 33 is fixedly connected to the side of the bracket 11 away from the material channel 2, and the middle of the support block 33 is provided with an installation groove for the protrusion 34 to be inserted. The protrusion 34 is hinged to the support block 33. The blocking strip 32 has two ends. One end is a drive end 321 that is hinged to the piston rod of the material blocking cylinder 31, and the other end is a blocking end 322 that extends to the surface of the conveyor belt 12 and faces the material channel 2. The blocking strip 32 is hinged to the side of the bracket 11 away from the material channel 2 through the hinge shaft 35.

[0040] When the piston rod of the blocking cylinder 31 retracts, it pulls the drive end 321, causing the stop bar 32 to rotate clockwise around the hinge shaft 35. The blocking end 322 then rotates toward the material channel 2 to prevent the generator claw pole from continuing to convey material backward and entering the material channel 2 it is currently facing. When the piston rod of the blocking cylinder 31 extends, it pushes the drive end 321, causing the stop bar 32 to rotate counterclockwise around the hinge shaft 35. The blocking end 322 then rotates away from the material channel 2 to allow the generator claw pole to continue conveying material backward without entering the material channel 2.

[0041] Reference Figure 2 , Figure 5The limiting mechanism 4 includes a support frame 41 fixedly connected to the upper side of the material channel 2, a gate plate 43 rotatably connected to the support frame 41, and a limiting cylinder 45 fixedly connected to the support frame 41. The gate plate 43 has a U-shaped cross-section and includes a material blocking plate 431, a material discharging plate 432, and an upper cover plate 433. The material blocking plate 431 is disposed on the side of the material discharging plate 432 near the conveying mechanism 1, and the upper cover plate 433 is fixedly connected between the top of the material blocking plate 431 and the top of the material discharging plate 432. A support shaft 42 passes through the upper cover plate 433, and both ends of the support shaft 42 are fixedly connected to the support frame 41. The support shaft 42 constitutes the rotation axis of the gate plate 43 to realize the rotational swing of the gate plate 43 relative to the support frame 41. A corner support plate 411 for supporting the cylinder body of the limiting cylinder 45 is fixedly connected to one side of the support frame 41. The piston rod of the limiting cylinder 45 is connected to a connecting shaft 44. The top of the upper cover plate 433 is provided with a connecting hole 434 for the piston rod of the limiting cylinder 45 to pass through. The side wall of the upper cover plate 433 is provided with a waist-shaped hole 435 for the connecting shaft 44 to be inserted. The connecting hole 434 communicates with the waist-shaped hole 435.

[0042] When the piston rod of the limit cylinder 45 extends downward, the connecting shaft 44 is constrained by the oblong hole 435. The connecting shaft 44 slides along the wall of the oblong hole 435 towards the end in the material feeding direction of the material channel 2, causing the gate plate 43 to rotate around the support shaft 42 in the material feeding direction of the material channel 2. The blocking plate 431 moves downward to prevent the next generator claw pole from entering the bottom of the gate plate 43, while the discharge plate 432 moves upward to release a generator claw pole at the bottom of the gate plate 43. When the piston rod retracts upward, the connecting shaft 44 slides along the wall of the oblong hole 435 towards the end in the loading platform 5, causing the gate plate 43 to rotate around the support shaft 42 towards the loading platform 5. The blocking plate 431 moves upward to release the next generator claw pole into the bottom of the gate plate 43, while the discharge plate 432 moves downward to prevent the generator claw pole on the material channel 2 from continuing to slide down.

[0043] Reference Figure 2 , Figure 6 The loading platform 5 includes a frame 51, a waiting area 52, a gripping area 53, and a support plate 54. The waiting area 52 and the gripping area 53 are both fixedly connected to the platform surface of the frame 51, with the waiting area 52 located on the side of the gripping area 53 away from the material channel 2. The support plate 54 is fixedly connected to one side wall of the frame 51. The waiting area 52 receives the generator claw poles from the material channel 2, and the gripping area 53 receives the generator claw poles after they have been flipped by the flipping mechanism 6. Vertical baffles 521 are fixedly connected to the three sides of the gripping area 53, except for the material inlet direction of the material channel 2, to block the generator claw poles and prevent them from interfering with the normal operation of the flipping mechanism 6 due to inertial sliding. The gripping area 53 has grooves 531 that match the shape of the claw fingers 200 of the generator claw poles, used to limit the position of the generator claw poles and prevent them from shifting after flipping, facilitating subsequent gripping and positioning by the robotic arm.

[0044] Reference Figure 3 , Figure 6 The flipping mechanism 6 is mounted on the platform surface of the stand 51 and is positioned between the rotating area 52 and the gripping area 53. The flipping mechanism 6 includes a drive cylinder 61, a slider 62, a rack 63, a gear 64, a rotating shaft 65, and a pneumatic gripper 66. The cylinder body of the drive cylinder 61 is fixedly connected to the support plate 54. The piston rod of the drive cylinder 61 and the rack 63 are both fixedly connected to the slider 62, and the rack 63 and the gear 64 mesh with each other. The rotating shaft 65 passes through both side walls of the stand 51, with one end fixedly connected to the gear 64, and the middle of the rotating shaft 65 fixedly connected to the pneumatic gripper 66.

[0045] The piston rod of the drive cylinder 61 extends and retracts, which is converted into the reciprocating linear motion of the rack 63 by the slider 62. This drives the gear 64 and the rotating shaft 65 to rotate in both directions, so as to realize the pneumatic gripper 66 to rotate 180 degrees with the rotating shaft 65 as the axis of rotation, so that the rotated generator claw pole is inserted into the groove 531 with the claw fingers 200 facing down.

[0046] The coordinated operation of the limiting mechanism 4 and the flipping mechanism 6 is as follows: when the pneumatic gripper 66 grips the generator claw pole located in the waiting area 52, the telescopic rod of the limiting cylinder 45 retracts, the discharge plate 432 moves downward, and the generator claw pole located under the gate plate 43 is prevented from entering the waiting area 52; when the pneumatic gripper 66 flips the claw pole to the gripping area 53, the telescopic rod of the limiting cylinder 45 extends, the discharge plate 432 moves upward, and the claw pole located under the gate plate 43 is allowed to enter the waiting area 52.

[0047] The implementation principle of the generator claw pole interval feeding device in this application embodiment is as follows: the generator claw poles are conveyed on the conveying mechanism 1, the blocking mechanism 3 diverts the generator claw poles into different material channels 2, and through the coordinated work of the limiting mechanism 4 and the flipping mechanism 6, the generator claw poles in the material channel 2 are pushed to the limit position, so that the generator claw poles enter the waiting area 52 at intervals. Then, the pneumatic gripper 66 grabs the generator claw poles in the waiting area 52 and flips them so that they are placed in the gripping area 53 with the claw fingers 200 facing down, so that the robotic arm of the next station can grip the generator claw poles in a fixed position, thereby completing the entire process of interval feeding of generator claw poles.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
