[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0017] This utility model provides a double-layer turntable mechanism, which includes: a large turntable 1; a small turntable 2 disposed on the inner side of the large turntable 1, wherein the diameter of the small turntable 2 is smaller than the diameter of the large turntable 1; wherein, a rotating component is disposed at the bottom of the large turntable 1, and the large turntable 1 can be rotated by the rotating component; lifting components are disposed on both sides below the large turntable 1, which can make the large turntable 1 slightly adjustable up and down; multiple fixtures 3 are installed on the top of the large turntable 1, and the multiple fixtures 3 are equidistantly distributed along the edge of the large turntable 1, and a three-jaw cylinder is installed on the top of each fixture 3; multiple workstation sensors 4 are installed on the top of the small turntable 2, and the multiple workstation sensors 4 are distributed along the edge of the small turntable 2.
[0018] It should be noted that: the large turntable 1, as the main load-bearing component of the entire device, has a large diameter that provides sufficient space to install multiple fixtures 3, enabling multi-station processing operations. The rotating component at the bottom allows the large turntable 1 to rotate, sequentially delivering the fixtures 3 mounted on it to different processing positions, achieving streamlined operation and improving production efficiency. The top of the small turntable 2 is equipped with multiple station sensors 4, which detect the working status of each station on the large turntable 1. For example, they detect whether the workpiece is in position or whether processing is complete. The small turntable 2 is located inside the large turntable 1 and has a smaller diameter, allowing the station sensors 4 to accurately correspond to each fixture 3 on the large turntable 1, achieving precise station detection. The bottom of the small turntable 2 is connected to multiple support legs for support. The rotating component provides rotational power to the large turntable 1 and controls its rotation angle, ensuring that each fixture 3 accurately stops at its predetermined processing position, which is crucial for ensuring processing accuracy. The lifting components on both sides of the large turntable 1 allow for fine-tuning of its height. During processing, the height of the turntable 1 may need to be adjusted according to the height requirements of different workpieces or the position of the processing tools to ensure processing accuracy and stability. The fixture 3 is used to fix the workpiece to be processed. Its top-mounted three-jaw cylinder enables centering and clamping of workpieces of different shapes and sizes, ensuring the workpiece does not move during processing. It also has an automatic product center positioning function, and the opening and closing positions of the clamps are flexibly adjustable to adapt to diverse workpiece processing needs, further improving the versatility and processing accuracy of the device. The station sensor 4 monitors the processing status of each station on the large turntable 1 in real time and feeds the detected information back to the control system. When the sensor detects that processing at a certain station is incomplete, the control system can pause the rotation of the large turntable 1 and wait for processing to complete. The station sensor 4 and the three-jaw cylinder are existing mature technologies and will not be described further here.
[0019] In an embodiment of this utility model, the rotating component includes a divider 5, which is located below the large turntable 1. The output end of the divider 5 is connected to a rotating shaft 51. The top of the rotating shaft 51 passes through the small turntable 2 and is connected to multiple connecting brackets 52. The end of each connecting bracket 52 away from the rotating shaft 51 is connected to the top of the large turntable 1. A support base 53 is installed on the top of the small turntable 2, and an air slip ring 54 is installed on the top of the support base 53. The multiple connecting brackets 52 are equidistantly distributed along the axis of the rotating shaft 51.
[0020] It should be noted that the divider 5 is a key component for realizing the intermittent motion of the large turntable 1. It converts continuous rotational motion into precise intermittent rotation, ensuring that the large turntable 1 stops accurately at each station for corresponding processing operations. By precisely controlling the rotation angle and dwell time of the large turntable 1, the divider 5 helps improve the processing accuracy of the entire device. The rotating shaft 51, as the output end of the divider 5, transmits the intermittent rotational power generated by the divider 5 to the large turntable 1. It is a crucial link in the entire power transmission chain, ensuring that power is stably transmitted from the divider 5 to the large turntable 1. The rotating shaft 51 passes through the small turntable 2, providing vertical support for the large turntable 1. Simultaneously, it provides a mounting base for the connecting frame 52, ensuring the connection stability between the large turntable 1 and the divider 5. The connecting frame 52 connects the rotating shaft 51 to the large turntable 1, serving to transmit torque. Multiple connecting frames 52 are equidistantly distributed along the axis of the rotating shaft 51, uniformly transmitting the power of the rotating shaft 51 to the large turntable 1, ensuring the stability of the large turntable 1 during rotation. Meanwhile, the connecting frame 52 also provides additional support for the large turntable 1, preventing deformation or wobbling during rotation and when carrying workpieces. The support base 53 is mounted on top of the small turntable 2, providing a mounting base for the air slip ring 54. It ensures the stable operation of the air slip ring 54 on the small turntable 2. The divider 5 drives the large turntable 1 to rotate, and the air piping relies on the air slip ring for rotation. The divider 5 is existing and mature technology and will not be described further here.
[0021] In an embodiment of this utility model, the lifting component includes a mounting base 6, which is located below the large turntable 1. Guide plates 61 are installed on both sides of the top of the mounting base 6, and a sliding plate 62 is slidably connected between the two guide plates 61. A lifting block 63 is connected to the top of the sliding plate 62, and a pushing block 64 is connected to the side of the sliding plate 62 away from the large turntable 1. An electric push rod 65 for driving the pushing block 64 to reciprocate is installed on the mounting base 6.
[0022] It should be noted that the mounting base 6, as the basic structure of the entire lifting assembly, is located below the large turntable 1 and bears the reaction force throughout the lifting process. Two guide plates 61 are installed parallel to each other on the top sides of the mounting base 6, providing precise movement guidance for the sliding plate 62. The design of the guide plates 61 ensures that the sliding plate 62 can only move in a specific direction, avoiding deviation or tilting during the lifting process, thus ensuring the accuracy and stability of the lifting operation. The lifting block 63 is installed on top of the sliding plate 62 and is used to directly lift the large turntable 1. Its side closest to the large turntable 1 is designed as an inclined surface. As the sliding plate 62 moves horizontally, the inclined surface of the lifting block 63 gradually comes into contact with the large turntable 1, and the horizontal movement is converted into a vertical lifting force through the action of the inclined surface, thereby realizing the lifting operation of the large turntable 1. This design cleverly utilizes the geometric structure to achieve force conversion. The push block 64 is connected to one side of the sliding plate 62 and serves as the power transmission interface between the electric push rod 65 and the sliding plate 62. The extension and retraction of the electric push rod 65 directly acts on the push block 64, which transmits this linear thrust to the sliding plate 62, thereby driving the lifting block 63 to move.
[0023] The working principle of the double-layer turntable mechanism provided by this utility model is as follows: When the double-layer turntable mechanism is running, the power system, with the divider 5 as the core, converts the continuous rotational motion input by the motor into precise intermittent rotational motion. The rotating shaft 51 at the output end of the divider 5 passes through the small turntable 2 and is connected to the top of the large turntable 1 through multiple evenly distributed connecting frames 52, stably transmitting power to the large turntable 1, driving the large turntable 1 to rotate intermittently at a preset angle, and driving the fixture 3 to pass through each processing station in sequence. After the workpiece is placed in the fixture 3, the three-jaw cylinder is quickly activated, and adaptive centering and clamping are performed according to the shape and size of the workpiece to ensure that the workpiece remains stable during processing. During the rotation of the large turntable 1, the station sensor 4 on the top of the small turntable 2 continuously monitors the status of each station, detects in real time whether the workpiece is correctly loaded, whether the processing is completed, and other information, and feeds the data back to the control system. Once a processing abnormality occurs at a certain station, the control system immediately sends a command to pause the rotation of the large turntable 1, and resumes operation after the fault is eliminated, ensuring the continuity and accuracy of the processing flow. The air slip ring 54 is mounted on the support base 53 on top of the small turntable 2. During the rotation of the large turntable 1, it undertakes the task of transmitting gas and electrical signals between the rotating and stationary parts. Its internal precision structure ensures a stable supply of compressed air to the pneumatic tools on the large turntable 1, while also ensuring reliable transmission of electrical signals, providing stable working conditions for the electrical control equipment. When it is necessary to adjust the height of the large turntable 1 to accommodate different workpieces or processing tools, the electric push rod 65 is activated, pushing the push block 64, which drives the sliding plate 62 to move horizontally within the track defined by the guide plate 61. Since the side of the lifting block 63 closest to the large turntable 1 is designed with an inclined surface, the horizontal displacement of the sliding plate 62 is converted into a vertical lifting force through this inclined surface, realizing precise up-and-down fine adjustment of the large turntable 1. After the fine adjustment is completed, the electric push rod 65 stops moving, maintaining the large turntable 1 at the required height, ensuring smooth processing.
