Description

Technical Field

[0001] This application relates to the technical field of intelligent manufacturing equipment, and in particular to a feeding and replenishing device for trimming the inner hole of hardware parts. Background Technology

[0002] With the continuous development of industry and the constant innovation of technology, the requirements for the processing precision and production efficiency of hardware parts are becoming increasingly stringent. As a core link, the processing quality of the inner hole dressing of hardware parts directly affects the final performance of the hardware parts.

[0003] In the process of machining the inner hole of hardware parts, existing feeding and replenishing devices usually use a simple conveyor belt feeding method, which transports the hardware parts to the processing position via the conveyor belt, or a vibratory feeder feeding method, which uses the vibration of the vibratory feeder to arrange the hardware parts in an orderly manner and transport them to the designated position, and then uses a simple robotic arm to feed them. The robotic arm grabs the hardware parts and places them on the worktable of the processing equipment for processing. These conventional feeding and replenishing methods in the existing technology have obvious defects. On the one hand, they lack the ability to accurately position and flexibly transport the hardware parts, and cannot guarantee that the hardware parts arrive at the processing position accurately and efficiently, affecting the processing quality of the inner hole of the hardware parts. On the other hand, they are difficult to meet the needs of modern industry for efficient production and cannot achieve large-scale automated production.

[0004] Therefore, developing a feeding and replenishing device to improve the efficiency and quality of internal hole trimming in hardware parts has become an important issue that urgently needs to be addressed. Summary of the Invention

[0005] In order to improve the processing quality and efficiency of internal hole trimming of hardware parts, this application provides a feeding and replenishing device for internal hole trimming of hardware parts.

[0006] A feeding and replenishing device for internal hole trimming of hardware parts includes a processing punch and a vibrating feeding mechanism disposed on one side of the processing punch. The processing punch is provided with a first worktable, and the first worktable is provided with a processing groove for placing hardware parts. A second worktable extends from the end of the first worktable near the vibrating feeding mechanism. A conveying mechanism is provided on the second worktable, and the conveying mechanism includes a first conveying mechanism and a second conveying mechanism. The second workbench is also provided with a first slide rail and a second slide rail that are perpendicular to each other. The first conveying mechanism includes a first robotic arm and a first driving device that drives the first robotic arm to reciprocate on the first slide rail. The second conveying mechanism includes a second robotic arm and a second driving device that drives the second robotic arm to reciprocate on the second slide rail. The first robotic arm is used to receive hardware parts from the vibrating feeding mechanism and convey them to the handover station. The second robotic arm is used to receive hardware parts at the handover station and convey them into the processing tank.

[0007] Through the above technical solution, the feeding and replenishing device utilizes a vibrating feeding mechanism to achieve automatic feeding of hardware parts, ensuring the orderliness and stability of feeding. Furthermore, the hardware parts are fed through a first conveying mechanism and a second conveying mechanism. The first conveying mechanism transports the hardware parts from the vibrating feeding mechanism to the second conveying mechanism, which then precisely moves the hardware parts into the processing slot. The punch press then performs finishing processing on the hardware parts in the processing slot, effectively realizing the automatic feeding process of hardware parts and improving the feeding efficiency of hardware part processing. Moreover, the mutually perpendicular first and second slide rails make the conveying path of the hardware parts more reasonable, facilitating the precise delivery of the hardware parts to the processing slot for inner hole finishing processing, thereby improving the overall effect of inner hole finishing processing of hardware parts.

[0008] Furthermore, a connecting seat is also provided on the second workbench. The connecting seat is provided with a connecting through hole. The connecting through hole is located on the top of the connecting seat. The bottom of the connecting seat and the second workbench form a communicating slot for the first robot arm to pass through. The connecting through hole communicates with the communicating slot. The outlet end of the vibrating feeding mechanism is connected to a conveying conduit. The outlet end of the conveying conduit communicates with the connecting through hole of the connecting seat.

[0009] Through the above technical solution, the hardware parts in the vibrating feeding mechanism can smoothly pass through the connecting through hole of the connecting seat and enter the connecting slot through the conveying conduit. During the movement, the first robot receives the hardware parts falling from the connecting through hole through the connecting slot, and then conveys the hardware parts to the second conveying mechanism through the connecting slot. This structural design effectively realizes the material transfer between the vibrating feeding mechanism and the first robot, so that the hardware parts can be transported from the vibrating feeding mechanism to the first robot in an orderly manner, thereby realizing the precise transmission of hardware parts and improving the efficiency and stability of feeding and replenishment.

[0010] Furthermore, the first driving device includes a rocker assembly and a first driving motor. The rocker assembly is an L-shaped rocker, which is formed by a first rocker and a second rocker fixedly connected together. A rotating rod is fixed at the intersection of the first rocker and the second rocker. The output end of the first driving motor is connected to the rotating rod. The end of the second rocker away from the rotating rod is rotatably connected to the first manipulator. The first driving motor is used to drive the L-shaped rocker to reciprocate, thereby driving the first manipulator to reciprocate on the first slide rail.

[0011] Through the above technical solution, the first drive device adopts a combination of a rocker assembly and a first drive motor. The output end of the first drive motor is connected to the rotating rod, which can drive the L-shaped rocker to reciprocate. This effectively converts the circular motion of the motor into the reciprocating linear motion of the first manipulator on the first slide rail. Compared with other transmission methods, the design of the rocker assembly makes the motion transmission more stable and direct, and can accurately receive and transport hardware parts from the vibrating feeding mechanism to the handover station, improving the accuracy and efficiency of feeding. At the same time, the structure is simple, easy to install and maintain, and reduces the overall cost and failure rate of the equipment.

[0012] Furthermore, the first driving device also includes a telescopic rod assembly, which includes a movable rod and a fixed sleeve. The movable rod is telescopically fitted inside the fixed sleeve. The movable rod is fixedly connected to the first rocker arm. The end of the fixed sleeve away from the movable rod is fixed to the second worktable.

[0013] Through the above technical solution, a telescopic rod assembly is set on the second workbench. This structure can provide auxiliary support and guidance for the movement of the L-shaped rocker arm. When the first drive motor drives the L-shaped rocker arm to reciprocate to drive the first robot arm to move on the first slide rail, the telescopic rod assembly can ensure the stability and accuracy of the first rocker arm's movement, reduce swaying and deviation, and make the operation of the entire first conveying mechanism more reliable and efficient, which is conducive to the stable conveying of hardware parts.

[0014] Furthermore, a first spring is sleeved on the outside of the telescopic rod assembly. One end of the first spring abuts against the fixed end of the fixed sleeve, and the other end abuts against the end of the movable rod near the first rocker arm.

[0015] By using the above technical solution, a first spring is sleeved on the outside of the telescopic rod assembly, and the two ends of the first spring abut against the fixed end of the fixed sleeve and the end of the movable rod near the first rocker arm, respectively. When the first driving device drives the first manipulator to move, the telescopic rod assembly can buffer and dampen the rotation of the L-shaped rocker arm, ensuring the stability and accuracy of the first manipulator's movement and extending the service life of the device.

[0016] Furthermore, the second driving device includes a second driving motor, a cam, and a transmission component. The output end of the second driving motor is connected to the cam. One end of the transmission component contacts and engages with the contour of the cam, and the other end is connected to the second manipulator. The second driving motor drives the cam to rotate, thereby pushing the transmission component. The transmission component drives the second manipulator to perform reciprocating linear motion along the second slide rail.

[0017] Through the above technical solution, the second drive motor drives the cam to rotate, and then transmits the motion to the second robot arm through the transmission component, so that the second robot arm can make stable reciprocating linear motion along the second slide rail. This setting enables the second robot arm to receive hardware parts at the handover station and accurately transport them into the processing tank, realize the stable transport of hardware parts, ensure the efficient operation of the feeding and replenishing device, and improve the efficiency and accuracy of the internal hole finishing of hardware parts.

[0018] Furthermore, the first robotic arm includes a first sliding seat slidably connected to the first slide rail and a first pneumatic gripper disposed on the first sliding seat, and the second robotic arm includes a second sliding seat slidably connected to the second slide rail and a second pneumatic gripper disposed on the second sliding seat.

[0019] Through the above technical solution, the first sliding seat of the first robot arm is slidably connected to the first slide rail, and the first pneumatic gripper is set on the first sliding seat. The second sliding seat of the second robot arm is slidably connected to the second slide rail, and the second pneumatic gripper is set on the second sliding seat. This enables the two robot arms to move flexibly, accurately grasp and transport hardware parts, and improve the efficiency and accuracy of feeding and replenishing.

[0020] Furthermore, the processing punch press includes a lifting drive device and a movable base. The movable base includes a first base and a second base, which are arranged sequentially from top to bottom. A processing shaft for processing the hardware parts in the processing groove is installed at the bottom of the first base. A plurality of first guide rods are connected to the bottom of the first base. The other end of the first guide rod passes through the first worktable and is connected to the second base. The first guide rod is slidably engaged with the first worktable. A top column is provided on the second base, and a protrusion that is tightly engaged with the processing groove is provided on the top column. The lifting drive device is used to drive the first base to reciprocate, thereby driving the second base and the protrusion to reciprocate.

[0021] Through the above technical solution, the first guide rod of the punch press passes through the first worktable and connects to the second base, and slides with the first worktable to ensure the stability and accuracy of the movement. When the lifting drive device can drive the first base to reciprocate, it will drive the second base to reciprocate. At the same time, the top column on the second base is provided with a protrusion that closely cooperates with the processing groove. During processing, the protrusion on the second base moves downward with the first base, and the hardware falls into the processing groove. The processing shaft at the bottom of the first base can trim the inner hole of the hardware in the processing groove, effectively realizing the precise positioning and processing of the hardware, improving processing efficiency and quality, and ensuring the stability and reliability of processing. After processing is completed, the second base moves upward with the movement of the first base, and the protrusion on the second base pushes the hardware out of the processing groove, preparing for the inner hole trimming of the next hardware, thus improving the processing efficiency of the hardware.

[0022] Furthermore, the movable base also includes a third base, which is disposed between the first base and the first worktable. The third base has a machining hole for the machining axis to pass through. The third base is slidably engaged with the first guide rod and is elastically connected to the first worktable through a first elastic element. The bottom of the second base is also provided with a fixed base. The second base and the fixed base are slidably engaged through a second guide rod, and the fixed base is provided with a second elastic element. The second base is elastically connected to the fixed base through the second elastic element.

[0023] Through the above technical solution, the third base is located between the first base and the first worktable, and is provided with machining holes for the machining axis to pass through, which can ensure that the machining axis can smoothly perform machining operations on the hardware parts; furthermore, the third base is slidably engaged with the first guide rod and elastically connected to the first worktable through the first elastic element, which can buffer the impact force generated during machining, reduce damage to the first worktable, and improve the stability of hardware part machining; secondly, a fixed base is provided at the bottom of the second base, and the two are slidably engaged with each other through the second guide rod, and the second base is elastically connected to the fixed base through the second elastic element, which can further buffer and reduce shock, enhance the stability of the machining punch, extend the service life of the machining punch, and at the same time ensure the accuracy and quality of the internal hole finishing machining of the hardware parts.

[0024] Furthermore, the lifting drive device is a crank-slider mechanism, which includes a third drive motor, a flywheel driven by the third drive motor, and a crank coaxially arranged with the flywheel. The crank is connected to the first base through a connector, and the third drive motor drives the flywheel to rotate, thereby driving the reciprocating linear motion of the first base.

[0025] Through the above technical solution, the lifting drive device is set as a crank-slider mechanism. A third drive motor drives the flywheel to rotate, which in turn drives the coaxial crank to rotate. The connecting component then causes the first base to perform reciprocating linear motion. This structure converts the motor's circular motion into linear motion, providing stable power for the internal hole trimming of hardware parts and ensuring smooth processing.

[0026] In summary, this application includes at least the following beneficial technical effects: 1. The feeding and replenishing device provided by the present invention utilizes the coordinated operation of a vibrating feeding mechanism, a first conveying mechanism, and a second conveying mechanism to achieve automatic feeding of hardware parts, thereby improving feeding efficiency and meeting the requirements of large-scale automated production. 2.

The lifting drive device of the punch press of the present invention drives the movable base and the protrusion to reciprocate, so that the processing shaft performs internal hole trimming on the hardware in the processing groove, thereby improving the processing accuracy of the internal hole trimming of the hardware.

[0030] See Figure 1-2 This invention provides a feeding and replenishing device for trimming the inner hole of hardware parts, including a processing punch press 1 and a vibrating feeding mechanism 2. The vibrating feeding mechanism 2 is disposed beside the processing punch press 1. The processing punch press 1 is provided with a first worktable 11, and the first worktable 11 is provided with a processing groove 111 for placing hardware parts 3. A second worktable 4 extends from the end of the first worktable 11 near the vibrating feeding mechanism 2. The second worktable 4 is provided with a first slide rail 41, a second slide rail 42 and a conveying mechanism, wherein the first slide rail 41 and the second slide rail 42 are perpendicular to each other, and the conveying mechanism includes a first conveying mechanism 5 and a second conveying mechanism 6.

[0031] See Figure 3-4The first conveying mechanism 5 includes a first robotic arm 51 and a first driving device that drives the first robotic arm 51 to reciprocate on the first slide rail 41. The first driving device includes a rocker assembly 52 and a first driving motor 53. The rocker assembly 52 is an L-shaped rocker, which is formed by a first rocker 521 and a second rocker 522 fixedly connected. A rotating rod 523 is fixed at the intersection of the first rocker 521 and the second rocker 522. The output end of the first driving motor 53 is connected to the rotating rod 523. The end of the second rocker 522 away from the rotating rod 523 is rotatably connected to one end of the first robotic arm 51. When the first driving motor 53 is started, the first driving motor 53 drives the L-shaped rocker to reciprocate, thereby driving the first robotic arm 51 to reciprocate on the first slide rail 41.

[0032] To ensure the stability and accuracy of the movement of the first robotic arm 51, the first drive device also includes a telescopic rod assembly 54. The telescopic rod assembly 54 includes a movable rod 541 and a fixed sleeve 542. The movable rod 541 is telescopically fitted inside the fixed sleeve 542 and is fixedly connected to the first rocker arm 521. The end of the fixed sleeve 542 away from the movable rod 541 is fixed on the second worktable 4. A first spring 55 is fitted on the outside of the telescopic rod assembly 54. One end of the first spring 55 abuts against the fixed end of the fixed sleeve 542, and the other end abuts against the end of the movable rod 541 near the first rocker arm 521. When the first conveying mechanism 5 is started, the cooperation between the telescopic rod assembly 54 and the first spring 55 effectively buffers and dampens the rotation of the L-shaped rocker arm.

The second driving device includes a second driving motor 62, a cam 63 and a transmission component 64. The output end of the second driving motor 62 is connected to the cam 63. One end of the transmission component 64 is in contact with the contour of the cam 63, and the other end is connected to the second robotic arm 61. The second driving motor 62 drives the cam 63 to rotate, thereby pushing the transmission component 64. The transmission component 64 drives the second robotic arm 61 to reciprocate linearly along the second slide rail 42.

[0034] In order to better grasp the hardware parts 3 from the vibrating feeding structure, the first robot arm 51 includes a first sliding seat 511 slidably connected to the first slide rail 41 and a first pneumatic gripper 512 disposed on the first sliding seat 511.

[0035] Furthermore, in order to improve the stability and accuracy of the conveying hardware 3 of the conveying mechanism, a first fixed rod 43 is also provided on the second workbench 4. The first fixed rod 43 is located at the end of the first slide rail 41 away from the first pneumatic gripper 512. The first fixed rod 43 is connected to a second spring 431. The first robot arm 51 is provided with a second fixed rod 513. The other end of the second spring 431 is connected to the second fixed rod 513. The bottom of the second robot arm 61 is connected to a third spring 613. The end of the second slide rail 42 away from the second pneumatic gripper 612 is provided with a mounting base 421. The other end of the third spring 613 is connected to the mounting base 421. The second spring 431 and the third spring 613 extend and retract with the reciprocating motion of the first robot arm 51 and the second robot arm 61.

[0036] In order to enable the vibrating feeding mechanism 2 to smoothly transfer the hardware parts 3 to the first conveying mechanism 5, a connecting seat 44 is also provided on the second workbench 4. The connecting seat 44 is provided with a connecting through hole 441. The connecting through hole 441 is located on the top of the connecting seat 44. The bottom of the connecting seat 44 and the second workbench 4 form a connecting slot 442 for the first robot arm 51 to pass through. The connecting through hole 441 is connected to the connecting slot 442. The outlet end of the vibrating feeding mechanism 2 is connected to a conveying conduit 21. The outlet end of the conveying conduit 21 is connected to the connecting through hole 441 of the connecting seat 44. The vibrating feeding mechanism 2 is a vibrating plate. The hardware parts 3 in the vibrating plate can pass through the conveying conduit 21 in an orderly manner. The hardware parts 3 enter the connecting slot 442 of the connecting seat 44 through the connecting through hole 441.

[0037] Specifically, when the hardware part 3 falls into the connecting slot 442, the first drive motor 53 drives the L-shaped rocker arm to drive the first robot arm 51 to slide in the direction of the hardware part 3. The first pneumatic gripper 512 is used to grab the hardware part 3 and transport the hardware part 3 to the handover position. At the same time, the second robot arm 61 receives the hardware part 3 at the handover position, while the second pneumatic gripper 612 grabs the hardware part 3. The second drive motor 62 drives the second robot arm 61 to transport the hardware part 3 into the processing slot 111 to wait for processing.

[0038] See Figure 1 and Figure 6The punch press 1 includes a lifting drive device 12 and a movable base 13. The movable base 13 includes a first base 131 and a second base 132. The first base 131, the first worktable 11, and the second base 132 are arranged sequentially from top to bottom. A processing shaft 1311 for processing the hardware 3 in the processing groove 111 is installed at the bottom of the first base 131. A plurality of first guide rods 1312 are connected to the bottom of the first base 131. The other end of the first guide rod 1312 passes through the first worktable 11 and is connected to the second base 132. The first guide rod 1312 slides in cooperation with the first worktable 11. A top column 1321 is provided on the second base 132. A protrusion 1322 that fits tightly with the processing groove 111 is provided on the top column 1321. The lifting drive device 12 is used to drive the first base 131 to reciprocate, thereby driving the second base 132 and the protrusion 1322 to reciprocate.

[0039] To ensure the processing stability of the inner hole trimming of the hardware part 3 by the punch press 1, the movable base 13 also includes a third base 133. The third base 133 is disposed between the first base 131 and the first worktable 11. The third base 133 is provided with a processing hole 1331 for the processing shaft 1311 to pass through. The third base 133 is slidably engaged with the first guide rod 1312, and the third base 133 is elastically connected to the first worktable 11 through the first elastic element 1332. The bottom of the second base 132 is also provided with a fixed base 14. The second base 132 and the fixed base 14 are slidably engaged through the second guide rod 141, and the fixed base 14 is provided with a second elastic element 142. The second base 132 is elastically connected to the fixed base 14 through the second elastic element 142.

[0040] In this embodiment, the lifting drive device 12 is a crank-slider mechanism, which includes a third drive motor 121, a flywheel 122 driven by the third drive motor 121, and a crank 123 coaxially arranged with the flywheel 122. The crank 123 is connected to the first base 131 through a connector 124. When the lifting drive device 12 is started, the third drive motor 121 drives the flywheel 122 to rotate, thereby the crank 123 drives the first base 131, the second base 132, the third base 133 and the protrusion 1322 to reciprocate through the connector 124.

[0041] The implementation principle of this invention is as follows: the vibrating feeding mechanism 2 sends the hardware part 3 to the position of the connecting slot 442 of the connecting seat 44 via the conveying conduit 21. The first driving device drives the first robotic arm 51 to grab the hardware part 3 and pass it through the connecting slot 442 to the handover position. Then, the second driving device drives the second robotic arm 61 to grab the hardware part 3 and send it to the processing slot 111 of the processing punch press 1. The lifting driving device 12 of the processing punch press 1 drives the first base 131 to move downward, thereby driving the second base 132 and the third base. The protrusion 1322 on the first base 133 and the second base 132 moves downward, and the hardware part 3 falls into the processing groove 111. The processing shaft 1311 on the first base 131 passes through the third base 133 to perform inner hole trimming on the hardware part 3. After trimming, the first base 131 moves upward under the action of the lifting drive device 12, and the protrusion 1322 on the second base 132 pushes the hardware part 3 out of the processing groove 111, waiting for the next hardware part 3 to be processed, thereby realizing the automated feeding and processing of the feeding and replenishing device.

[0042] It should be noted that the feeding and replenishing device for trimming the inner hole of hardware parts provided by the present invention uses a controller to uniformly drive each motor and pneumatic gripper during the entire feeding, conveying and processing process, so as to realize the fully automated operation of the process.

[0043] 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.
