Description

Technical Field

[0001] This invention relates to the field of planetary gear processing equipment technology, specifically to a planetary gear processing device with a bidirectional feeding mechanism. Background Technology

[0002] In planetary gear machining, the accuracy and automation of feeding directly affect production efficiency and product quality. However, traditional machining equipment has many technical limitations: First, the feeding method is singular, mostly unidirectional, only able to transport blanks, while finished products need to be manually transferred, resulting in low automation. Second, the positioning accuracy is insufficient; the blank placement lacks a precise positioning benchmark, clamping is unstable, and it is prone to deviation during processing, leading to gear accuracy deviations. Third, the conveying mechanism has poor stability; the conveyor belt is prone to wear and slippage, affecting the continuity of blank transport. Fourth, the feeding mechanism lacks flexibility; the clamping structure cannot adapt to planetary gears of different sizes, resulting in poor versatility. Fifth, the coordination between various mechanisms is poor; the connection between conveying, feeding, and processing is not smooth, easily causing jams and affecting the production rhythm.

[0003] While some related patented technologies already exist in the industry, significant shortcomings remain: Patent CN202221876543.9 (A planetary gear processing feeding device): It adopts a unidirectional feeding structure, and the finished product needs to be handled manually, resulting in low automation. The blank positioning is only achieved through a simple clamp, and the positioning accuracy is limited (deviation ≥ 0.1mm). The clamping structure is fixed and cannot be adapted to gears of different sizes.

[0004] Patent CN202121987654.7 (Automatic feeding mechanism for gear processing): It supports automated feeding, but the conveying mechanism is not designed to be wear-resistant and is prone to wear after long-term use; the feeding mechanism lacks rotation adjustment function and the gripping angle is limited; the coordination between the various mechanisms is poor and the connection between feeding and processing is stuck.

[0005] Patent CN202320567890.1 (Feeding device for planetary gear processing): The bidirectional feeding function is imperfect, and the finished product transfer efficiency is low; the blank clamping is a two-point clamping, which is not stable enough; the support structure of the conveyor frame is weak and it is easy to shake during operation.

[0006] Patent CN202010987654.2 (Automated Gear Processing Feeding System): It has a high degree of automation, but the clamping structure is complex and the maintenance cost is high; the positioning accuracy of the feeding robot is insufficient and the blank placement deviation is large; the conveyor belt has no tension adjustment function and is prone to slippage.

[0007] The aforementioned existing technologies have not solved the core problems of "bidirectional automated feeding - precise positioning and clamping - stable conveying - flexible adaptation - collaborative efficiency", and are difficult to meet the high precision and high efficiency requirements of mass production of planetary gears. There is an urgent need for a processing device with an optimized design and a bidirectional feeding mechanism. Summary of the Invention

[0008] The purpose of this invention is to provide a planetary gear processing device with a bidirectional feeding mechanism to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a planetary gear processing device with a bidirectional feeding mechanism. The processing device mainly includes a planetary gear processing machine tool processing table for carrying the processing operation, a conveying mechanism for conveying planetary gear blanks, and a bidirectional feeding mechanism for achieving bidirectional precise feeding. The conveying mechanism is arranged between the planetary gear processing machine tool processing tables to achieve long-distance conveying of the blanks. The bidirectional feeding mechanism is correspondingly arranged on one side of the conveying mechanism to transfer the blanks on the conveying mechanism to the processing table and to transfer the processed gears to a designated position. The three mechanisms cooperate with each other to achieve automated processing and feeding of planetary gears.

[0010] Preferably, the top end face of the planetary gear processing machine tool's processing table is equipped with a mounting base by a secure fixed installation method. The mounting base is used to position and place the planetary gear blank to be processed. The top of the mounting base is provided with a positioning groove that matches the contour of the planetary gear blank, providing a precise positioning reference for the blank. Furthermore, three limiting grooves are provided at intervals along the circumferential direction on the outer edge of the mounting base. The limiting grooves and the positioning grooves are interconnected, used to accommodate clamping components and provide space for their movement.

[0011] Preferably, a connecting block is fixedly installed at the outer edge of the mounting base corresponding to the three limiting grooves. The connecting block is a block-shaped support structure used to provide a stable mounting base for the clamping cylinder. A clamping cylinder is fixedly installed on each connecting block. The output end of the clamping cylinder faces the positioning groove and is fixedly connected to a clamping head. The clamping head is located in the limiting groove. The clamping cylinder drives the clamping head to move, thereby clamping and fixing the blank in the positioning groove.

[0012] Preferably, the conveying mechanism includes a connecting frame for connecting and supporting, the connecting frame is a horizontal frame structure, and symmetrically arranged conveying frames are mounted on both sides of the connecting frame by a fixed installation method. The conveying frames are used to install conveying components. Each of the conveying frames is provided with a conveyor belt for carrying the blank, and the conveyor belt is made of wear-resistant material to ensure the stability of long-term conveying operations.

The conveyor motor drives the conveyor roller to rotate, thereby driving the conveyor belt to run synchronously; support feet are fixedly installed at the four corners of the bottom of the conveyor frame to provide stable support for the conveying mechanism.

[0014] Preferably, the bidirectional feeding mechanism includes a feeding robot for precise transfer. The feeding robot is mounted on a base by a fixed installation method. The base is a heavy-duty block structure, which can improve the stability of the feeding robot during operation and prevent shaking. The end of the robotic arm of the feeding robot is provided with a clamping structure for clamping the blank and the finished gear. The clamping structure enables the stable gripping and transfer of materials.

[0015] Preferably, the clamping structure includes a rotating shaft installed at the end of the robotic arm of the feeding robot. The rotating shaft can drive the subsequent clamping components to rotate, adapting to different angle gripping requirements. A concave plate is fixedly connected to the bottom end of the rotating shaft for mounting drive and transmission components. A micro motor is fixedly installed on one outer wall of the concave plate. The output end of the micro motor faces the inside of the concave plate and is fixedly connected to a bidirectional threaded shaft. The other end of the bidirectional threaded shaft passes through to the other side of the concave plate through a bearing to ensure stable rotation. A guide rod is also horizontally connected between the two sides of the concave plate. The guide rod is arranged parallel to the bidirectional threaded shaft to provide guidance and limiting.

[0016] Preferably, two opposing clamping blocks are fitted on both the bidirectional threaded shaft and the guide rod. The clamping blocks have matching threaded holes corresponding to the bidirectional threaded shaft and matching guide holes corresponding to the guide rod. Through threaded engagement and guide limiting, the two clamping blocks can move relative to or towards each other along the bidirectional threaded shaft and the guide rod. The bottom of the clamping block is integrally formed with a convex clamping plate, which is used to directly fit and clamp the planetary gear blank or finished gear, improving the stability and fit of the clamping.

[0017] This invention provides a planetary gear processing device with a bidirectional feeding mechanism. It has the following advantages: 1. This invention enables bidirectional operation of billet loading and finished product unloading via a bidirectional feeding robot, without human intervention. It accurately transfers the billet from the conveyor belt to the processing table, and after processing, the finished product is transferred to the designated position, achieving full automation. The feeding robot's robotic arm is flexible and controllable, and with the rotating axis, it can adapt to different angles of gripping and transferring. The feeding path is precise, greatly shortening the feeding time and improving the efficiency of mass production.

[0018] 2. This invention provides a reliable positioning reference for the blank by precisely matching the positioning groove of the mounting base with the contour of the planetary gear blank; the clamping cylinder in the three limiting grooves drives the clamping head to clamp the blank synchronously, with uniform clamping force, ensuring that the blank is fixed without deviation or deformation; the clamping structure of the feeding robot cooperates with the guide rod through the bidirectional threaded shaft to make the clamping block accurately centered and clamped, and the blank posture is stable during the transfer process, further ensuring the processing positioning accuracy and improving the consistency of gear processing dimensions and tooth profile accuracy.

[0019] 3. The present invention uses a heavy-duty block structure for the base to provide stable support for the feeding robot and prevent it from shaking during operation; the support feet at the bottom of the conveyor frame work together with the connecting frame to ensure smooth operation of the conveying mechanism and no deviation in the conveying of the blank; the convex clamping plate of the clamping structure has a high degree of fit with the gear, and the clamping is stable, preventing the blank or finished product from falling off during processing and reducing safety hazards; all components are firmly connected, and are not easy to loosen or deform during long-term high-speed operation, thus extending the service life of the device.

[0020] 4.

The conveyor belt is made of wear-resistant material, enabling stable long-distance transport of blanks and suitable for large-scale batch production scenarios. The coordinated control of the clamping cylinder and the feeding robot allows for flexible adjustment of feeding and clamping timing according to the processing rhythm, adapting to different processing requirements and enhancing the flexibility and practicality of the device.

The clamping structure enables the stable gripping and transfer of materials. Example

[0032] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: The clamping structure includes a rotating shaft 34 installed at the end of the robotic arm of the feeding robot 33.

The wear-resistant conveyor belt and adjustable support feet of the conveying mechanism ensure stable conveying and prevent slippage. Next, the feeding robot 33 receives a signal, the robotic arm moves above the blank, the rotating shaft 34 adjusts the clamping angle, and the micro motor 36 drives the bidirectional threaded shaft 37 to rotate, causing the two clamping blocks 39 to move relative to each other along the guide rod 38. The convex clamping plate 40 clamps the blank. The bidirectional threaded design of the clamping structure ensures... The feeding robot ensures uniform and stable clamping force.

Three clamping cylinders 23 on the outer wall of the mounting base drive the clamping head 24 to move, clamping the blank from three directions to prevent it from shifting during processing. After processing, the clamping cylinders are released, and the clamping structure of the feeding robot moves again to grab the finished gear and transfer it to the designated finished product area.
