Description

Technical Field

[0001] This invention relates to the field of industrial equipment, specifically to an automatic rotary device that supports multi-station collaboration. Background Technology

[0002] In fields such as machining, electronic assembly, and automotive parts manufacturing, multi-station collaborative production is a key model for improving efficiency. Automated rotary tables, as core equipment in multi-station collaboration, need to achieve precise transfer and stable positioning of workpieces between different stations to connect drilling, assembly, and inspection processes. Currently, these devices are widely used in mass production scenarios, using the rotation of a rotary table to switch workpieces between stations, reducing manual handling time and improving overall production cycle time. However, with the continuous increase in production precision and efficiency requirements, existing automated rotary tables are gradually showing shortcomings in structural design and functional adaptability, making it difficult to fully meet the high-efficiency and precision demands of multi-station collaboration.

[0003] Existing automatic rotary devices supporting multi-station collaboration have several problems: First, the drive structure and clamping mechanism are mostly independently controlled, requiring additional electrical sensors or control modules to achieve linkage between the two. This not only increases equipment costs but also easily leads to asynchronous station switching and clamping actions due to signal delays, affecting processing accuracy. Second, workpiece positioning relies on manual assistance or a single fixed structure, lacking a flexible pre-positioning mechanism. When dealing with workpieces of different sizes, frequent adjustments to positioning components are required, making the operation cumbersome, time-consuming, and with poor adaptability. Third, the clamping mechanism often uses a single component drive, making it difficult to control the clamping force evenly. This easily leads to workpiece slippage or surface damage, and the reset mechanism lacks stability, easily causing clamping failure due to spring fatigue after long-term use. Fourth, the design of the rotary table's support and limit structure is imperfect, easily causing radial offset during rotation, resulting in station positioning deviations and affecting the continuity of multi-process collaboration. Summary of the Invention

[0009] As a further preferred embodiment of this technical solution: the lower end of the support shaft is fixedly disposed at the middle position of the upper side of the support base plate, the support shaft is disposed through the middle position of the rotary table, the worm gear and the rotating cylinder, the connecting plate is disposed on the upper side of the rotary table, and the shape and position of the drive arc groove are irregularly circular.

[0010] As a further preferred embodiment of this technical solution: the gripper assembly includes a driven connecting plate, one end of which is connected to a first spring, and a push rod is connected to the upper side of the driven connecting plate. The gripper assembly also includes a connecting shell, a connecting rod is connected to the push rod, and a positioning gripper is connected to the end of the connecting rod away from the push rod.

[0011] As a further preferred embodiment of this technical solution: the driven connecting plate is connected to a drive shaft on the lower side of the end away from the first spring, and the drive shaft is slidably and rotatably connected to the inner side of the drive arc groove. The driven connecting plate is slidably connected to the inner side of the connecting shell. The push rod is slidably connected to a groove provided in the middle of the upper side of the connecting shell. The two ends of the first spring are respectively fixedly connected to the inner side of the connecting shell and the side of the driven connecting plate away from the drive shaft.

[0012] As a further preferred embodiment of this technical solution: the push rod is slidably connected to a groove provided on the connecting rod, the end of the connecting rod away from the push rod is fixedly connected to one end of the positioning gripper, the connection between the connecting rod and the positioning gripper is rotatably connected to a shaft provided on one side of the connecting shell, and two sets of connecting rods and positioning grippers are provided respectively and symmetrically, and the two sets of connecting rods are arranged crosswise;

[0013] As a further preferred embodiment of this technical solution: the pre-positioning component includes a positioning ring slidably disposed inside the rotary table, a second spring connected to one side of the positioning ring, a limiting slide rod connected to the side of the positioning ring near the second spring, a pull rod connected to the lower side of the positioning ring, and the pre-positioning component also includes a limiting slide groove disposed inside the rotary table.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the mechanical linkage design of the drive component and the gripper component, the drive arc groove on the connecting plate rotates synchronously with the rotary table, directly driving the drive shaft of the gripper component to realize the opening and closing of the positioning gripper. No additional electrical control module is required, avoiding signal delay problems and ensuring precise synchronization between workstation switching and clamping action. This solves the problem of existing devices relying on electrical control and having poor synchronization.

[0017] 2. The pre-positioning component employs two sets of symmetrically arranged positioning rings, working in conjunction with a second spring to achieve elastic pre-positioning of the workpiece. The spacing between the positioning rings can be adjusted by pulling the lever, adapting to workpieces of different sizes. This structure eliminates the need for frequent disassembly and assembly of the positioning components, making operation convenient and significantly improving the device's adaptability to workpieces of various specifications. It solves the problems of low flexibility and poor adaptability in the pre-positioning mechanism of existing devices.

[0018] 3. The gripper assembly adopts two sets of cross-arranged connecting rods and positioning grippers to form a scissor clamping structure. Combined with the pre-compression design of the first spring, the clamping force is evenly applied to both sides of the workpiece, avoiding workpiece slippage or surface damage. At the same time, the cooperation between the first spring and the driven connecting plate ensures stable reset after clamping, reducing the risk of failure caused by spring fatigue, and solving the problems of uneven clamping force and poor reset stability in existing clamping mechanisms.

[0019] 4. The limit connecting frame in the drive assembly plays a radial limiting role for the rotating cylinder. The support shaft passes through the middle position of the rotary table, worm gear and rotating cylinder, forming a double support and limit structure, which effectively avoids radial displacement when the rotary table rotates, ensures the positioning accuracy of the work station, and ensures smooth and continuous cooperation of multiple processes. It solves the problem of insufficient rotary support and easy positioning deviation in the existing device. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] Please see Figures 1-9 As shown, the present invention provides a technical solution for an automatic rotary device that supports multi-station collaboration.

[0033] In some embodiments, the automated rotary device supporting multi-station collaboration can be applied to fields such as machining, electronic component assembly, and automotive parts production. Specifically, in machining, it can be used for continuous multi-process machining of workpieces, such as drilling, grinding, and milling; in electronic component assembly, it can achieve precise positioning and collaborative assembly of components; and in automotive parts production, it can be adapted for batch processing and transfer of parts of different specifications. Figure 1 In this embodiment, the device is used as an example of multi-station continuous drilling operation in the field of machining. Of course, similar structures can also be used in multi-station collaborative scenarios in other application fields, which will not be described in detail below.

[0034] It is understandable that the schematic diagram only illustrates the core components of the automatic rotary device: support base plate 1, rotary table 2, drive assembly 3, gripper assembly 4, and pre-positioning assembly 5. The actual shape, size, and position of these components are not limited by the schematic diagram. For example, the rotary table 2 can be designed as circular or polygonal, the size of the support base plate 1 can be adjusted according to the number of workstations and the size of the workpiece, and the installation position of the drive assembly 3 can be optimized according to the spatial layout. The device may also include auxiliary components such as protective covers, waste collection troughs, and workstation identification modules to improve operational safety and practicality.

[0035] In some embodiments, the automatic rotary device supporting multi-station collaboration includes a support base plate 1, a rotary table 2, a drive assembly 3, a gripper assembly 4, and a pre-positioning assembly 5. The support base plate 1 serves as the load-bearing foundation of the entire device, providing an installation reference for other components. The rotary table 2 is positioned above the support base plate 1 to support the workpiece and enable multi-station switching. The drive assembly 3 is installed between the support base plate 1 and the rotary table 2, providing power for the rotation of the rotary table 2. The gripper assembly 4 is positioned above the drive assembly 3 for positioning and clamping the workpiece. The pre-positioning assembly 5 is positioned below the gripper assembly 4 to pre-position the workpiece, ensuring subsequent clamping accuracy.

[0036] In this embodiment, the drive assembly 3 includes a drive motor 31, a worm gear 32, a worm wheel 33, a rotating cylinder 34, a limiting connecting frame 35, a support shaft 36, and a connecting plate 37. The drive motor 31 is a servo motor to ensure stable and precise speed control. The worm gear 32 and worm wheel 33 are made of high-strength alloy steel, and their meshing surfaces are heat-treated by quenching to improve wear resistance and transmission efficiency. The rotating cylinder 34 is made of seamless steel pipe to ensure structural rigidity. The limiting connecting frame 35 is made of cast iron and is fixed to the support base plate 1 with bolts. The support shaft 36 is a stainless steel round shaft, and the connecting plate 37 is a circular steel plate with an irregular annular drive arc groove 38 at its upper end.

[0037] Specifically, the drive motor 31 is fixedly mounted on the support base plate 1 with bolts, and its output end is fixedly connected to the worm gear 32 through a coupling. The end of the worm gear 32 away from the output end of the drive motor 31 is rotatably connected to the extension plate provided on the support base plate 1 through a bearing to ensure smooth rotation of the worm gear 32. The worm wheel 33 is meshed with the worm gear 32. The lower end of the rotating cylinder 34 passes through and is fixed in the middle position inside the worm wheel 33, and the upper end is fixedly connected to the lower middle position of the rotary table 2 with bolts to realize power transmission. The rotating cylinder 34 passes through and is rotatably connected to the limiting connecting frame 35 through a bearing. The limiting connecting frame 35 plays a radial limiting role for the rotating cylinder 34 to prevent deviation during rotation. The lower end of the support shaft 36 is fixedly set in the middle position of the upper side of the support base plate 1, passes through the middle position of the rotary table 2, the worm wheel 33 and the rotating cylinder 34, and its upper end is fixed to the connecting plate 37 by welding. The connecting plate 37 is set on the upper side of the rotary table 2, and the drive arc groove 38 is adapted to the drive shaft of the gripper assembly 4.

[0038] The core function of the drive assembly 3 is to provide stable power to the rotary table 2 and enable multi-station switching. During operation, the drive motor 31 starts, driving the worm gear 32 to rotate. The worm gear 32 drives the worm wheel 33 to rotate through meshing transmission. The worm wheel 33 drives the rotating cylinder 34 to rotate synchronously, thereby causing the rotary table 2 to rotate around the support shaft 36, achieving station switching. The limiting connecting frame 35 restricts the radial displacement of the rotating cylinder 34, ensuring rotational accuracy. The drive arc groove 38 on the connecting plate 37 rotates synchronously with the rotary table 2, providing triggering power for the clamping action of the gripper assembly 4, realizing rotation and clamping.

[0039] It should be noted that the rotational speed of the drive motor 31 can be adjusted according to the workstation switching requirements to adapt to different processing cycles; the transmission ratio between the worm gear 32 and the worm wheel 33 can be designed according to actual needs to ensure that the rotational speed of the rotary table 2 meets the operational requirements. In some other embodiments, the drive motor 31 can also be replaced with a stepper motor, without being limited to the selection of a servo motor, as long as precise speed control can be achieved.

[0040] In this embodiment, the gripper assembly 4 includes a driven connecting plate 41, a first spring 42, a push rod 43, a connecting shell 44, a connecting rod 45, and a positioning gripper 46. The driven connecting plate 41 is a rectangular steel plate with a drive shaft fixed to its lower end; the first spring 42 is a compression spring providing a restoring force; the push rod 43 is a stainless steel round rod that passes through the connecting shell 44; the connecting rod 45 is an alloy steel rod, with two sets of connecting rods 45 arranged crosswise; the positioning gripper 46 is made of wear-resistant alloy material and has anti-slip textures on its inner side to prevent slippage when the workpiece is clamped.

[0041] Specifically, the lower side of the driven connecting plate 41 away from the drive shaft is fixedly connected to the drive shaft, and the drive shaft is slidably and rotatably connected to the inner side of the drive arc groove 38; the driven connecting plate 41 is slidably connected to the inner side of the connecting shell 44, and the two ends of the first spring 42 are respectively fixedly connected to the inner side of the connecting shell 44 and the side of the driven connecting plate 41 away from the drive shaft, and are in a pre-compressed state in the initial state; the push rod 43 passes through and is slidably connected to the groove opened in the middle position of the upper side of the connecting shell 44, and the lower end is fixedly connected to the upper side of the driven connecting plate 41; one end of the connecting rod 45 is slidably connected to the push rod 43 through the groove, and the other end is fixedly connected to one end of the positioning claw 46. The connection between the connecting rod 45 and the positioning claw 46 is rotatably connected to one side of the connecting shell 44 through the shaft. The two sets of connecting rods 45 are arranged crosswise to form a scissor clamping structure.

[0042] It should be noted that the gripper assembly 4 is used for workpiece positioning and clamping, and works with the drive assembly 3 to achieve automatic clamping after station switching. When the rotary table 2 drives the connecting shell 44 to rotate, the drive shaft slides along the irregular annular drive arc groove 38 on the connecting plate 37. The change in the contour of the drive arc groove 38 pushes the drive shaft to drive the driven connecting plate 41 to slide along the inner side of the connecting shell 44, compressing the first spring 42. The driven connecting plate 41 drives the push rod 43 to move, and the push rod 43 drives the two sets of intersecting connecting rods 45 to rotate around the rotation axis, causing the positioning gripper 46 to close inward, thus clamping the workpiece. When the rotary table 2 rotates to the next station, the drive shaft resets along the drive arc groove 38, the first spring 42 releases its elastic potential energy, pushes the driven connecting plate 41 and the push rod 43 to reset, and the positioning gripper 46 opens, facilitating the loading and unloading of the workpiece.

[0043] Understandably, the inner shape of the positioning jaw 46 can be designed to fit the contour of the workpiece, such as an arc or V-shape, as long as stable clamping can be achieved; the stiffness of the first spring 42 can be adjusted according to the clamping force requirements to ensure that the workpiece is clamped stably without damaging the workpiece surface.

[0044] In this embodiment, the pre-positioning component 5 includes a positioning ring 51, a second spring 52, a limiting slide rod 53, a pull rod 54, and a limiting groove 55. The positioning ring 51 is an arc-shaped steel plate with an anti-slip rubber pad attached to its inner side; the second spring 52 is a compression spring that provides pre-positioning elasticity; the limiting slide rod 53 is a stainless steel round rod that serves as a guide; the pull rod 54 has a cylindrical structure for easy manual operation; and the limiting groove 55 is located inside the rotary table 2 and is adapted to the pull rod 54.

[0045] Specifically, the positioning ring 51 is slidably disposed inside the rotary table 2, with two sets symmetrically distributed; the two ends of the second spring 52 are respectively fixedly connected to the inner side of the rotary table 2 and the middle position of one side of the positioning ring 51, and are initially in a pre-compressed state; one end of the limiting slide rod 53 is fixedly connected to the side of the positioning ring 51 near the second spring 52, and the other end is slidably connected to the groove opened inside the rotary table 2; the pull rod 54 is fixedly connected to the lower side of the positioning ring 51, passes through and is slidably connected to the inner side of the limiting slide groove 55, and can slide along the limiting slide groove 55 to drive the positioning ring 51 to move.

[0046] In this embodiment, the pre-positioning component 5 is used for pre-positioning the workpiece, laying the foundation for the precise clamping of the gripper component 4. After the workpiece is placed on the rotary table 2, the two sets of positioning rings 51 move inward under the pre-pressure of the second spring 52, initially positioning the workpiece from both sides and limiting its horizontal displacement; the limiting slide rod 53 ensures that the positioning rings 51 slide smoothly and avoids deviation. When it is necessary to place workpieces of different sizes, the positioning rings 51 can be slid along the limiting slide groove 55 by pulling the pull rod 54, compressing the second spring 52, adjusting the distance between the two sets of positioning rings 51 to match the workpiece size; after releasing the pull rod 54, the positioning rings 51 reset under the action of the second spring 52, re-clamping the workpiece.

[0047] It should be noted that the curvature of the positioning ring 51 can be adjusted according to the shape of the rotary table 2 and the contour of the workpiece; the pre-compression of the second spring 52 can be finely adjusted by adjusting the stroke of the limiting slide bar 53 to adapt to the pre-positioning requirements of different workpieces. In some other embodiments, rollers can also be provided on the inner side of the positioning ring 51 to reduce the friction when the workpiece is placed, and positioning is not limited to using only anti-slip rubber pads.

[0048] Working principle or structural principle:

[0049] According to the size of the workpiece to be processed, pull the lever 54 to adjust the distance between the two sets of positioning rings 51, place the workpiece between the positioning rings 51 of the rotary table 2, and the positioning rings 51 pre-position the workpiece under the action of the second spring 52.

[0050] Start the drive motor 31, the worm gear 32 drives the worm wheel 33 to rotate, which in turn drives the rotating cylinder 34 to rotate synchronously with the rotary table 2 to realize the switching of work positions; at the same time, the connecting plate 37 rotates with the rotary table 2, driving the arc groove 38 to push the drive shaft of the gripper assembly 4, so that the positioning gripper 46 closes and accurately clamps the pre-positioned workpiece.

[0051] After the rotary table 2 drives the workpiece to the target station, the drive motor 31 stops, and the workpiece remains stable under the clamping action of the gripper assembly 4, thus completing the processing or assembly operation at that station.

[0052] After the operation at this station is completed, the drive motor 31 starts again, driving the rotary table 2 to rotate to the next station. The gripper assembly 4 remains clamped as the drive arc groove 38 moves, until all station operations are completed.

[0053] After all workstations have completed their operations, the rotary table 2 returns to its initial position, the drive arc groove 38 drives the gripper assembly 4 to reset, the positioning gripper 46 opens, the pull rod 54 is pulled to open the positioning ring 51, the processed workpiece is taken out, and the next round of operations is prepared.
