Description

Technical Field

[0001] This utility model belongs to the field of mechanical tooling technology, and specifically relates to a rotary tooling structure for mechanical automation equipment. Background Technology

[0002] In the field of automated mechanical manufacturing, rotary tooling structures, as core auxiliary equipment, are widely used in multi-process workflow scenarios such as workpiece processing, assembly, and inspection. Through precise workstation rotation switching, they achieve efficient connection of workpieces in different production stages, and are key components for ensuring the continuity of automated production lines and improving production efficiency. As mechanical manufacturing develops towards multi-variety and flexible directions, rotary tooling needs to frequently adapt to the workstation switching requirements of workpieces with different specifications, which places higher demands on its ease of operation, operational stability, and maintenance cost control.

[0003] Existing mechanical automation equipment using rotary tooling structures generally employs a design logic of multiple drive units + complex transmission links + linkage positioning mechanisms to achieve precise switching between multiple workstations. For example, multiple servo motors drive components such as the rotary table, positioning pins, and clamping assemblies, in conjunction with gear sets, synchronous belts, ball screws, and other transmission structures. A PLC control system then coordinates the actions of these components to complete a series of operations such as rotation, positioning, and locking during workstation switching. However, this design, relying on the coordinated operation of multiple components, has significant technical flaws, causing numerous problems in practical production applications.

[0004] The preparatory testing work before equipment commissioning is extremely demanding. Since the station switching accuracy of the rotary tooling directly depends on the coordination and consistency of each component, it is necessary to repeatedly debug and calibrate multiple parameters such as the speed of the drive motor, the transmission ratio of the transmission components, and the response time of the positioning mechanism. Furthermore, it is necessary to check the gap errors in the transmission link one by one. This process not only consumes a lot of time and manpower, but may also prolong the equipment commissioning cycle and affect the progress of the production plan due to improper debugging.

[0005] Furthermore, the complex collaborative structure significantly increases the subsequent maintenance costs of the equipment. The multi-component collaborative design means that the core functions of the rotating tooling require the maintenance of multiple drive devices, further increasing the maintenance frequency and overall operation and maintenance costs. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotary tooling structure for mechanical automation equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rotating tooling structure for mechanical automation equipment, including a platform, a base is provided on one side of the platform, an installation ring is fixedly inserted into the axis on the inner side of the platform, and a rotating rod is fixedly inserted into the inner side of the installation ring on the same axis. The end of the rotating rod away from the platform extends through to the inner side of the base and is coaxially fixedly fitted with a drive plate. The outer side of the drive plate is provided with an arc groove and a straight groove at equal intervals around the circumference, and there are four arc grooves and four straight grooves arranged in an alternating pattern.

[0008] Preferably, the end of the rotating rod away from the base has symmetrically arranged keyways, and a mounting key is inserted into the inner side of the keyway. The end of the mounting ring away from the base has symmetrically arranged key cavities, and both the keyways and key cavities are used in conjunction with the mounting key.

[0009] Preferably, the end of the rotating rod away from the platform is snapped into the axis of the drive plate, and the rotating rod is rotatably connected to the base via a bearing.

[0010] Preferably, a circular plate is provided on the side of the drive plate away from the platform, and a locking member located on the outer side of the drive plate is snapped onto the side of the circular plate closer to the platform.

[0011] Preferably, the outer surface of the engagement member is provided with an arc groove two, and the arc groove two is used in conjunction with the drive plate, and the outer surface of the engagement member is in contact with the arc groove one.

[0012] Preferably, a snap-fit ​​component is snapped onto the side of the circular plate near the platform, and the snap-fit ​​component is located on the outer surface of the interlocking component. The snap-fit ​​component is used in conjunction with the straight groove snap-fit ​​component.

[0013] Preferably, a shaft is coaxially mounted on the side of the circular plate away from the platform, and a bevel gear one is mounted on the end of the shaft away from the circular plate. A bevel gear two meshes with the surface of the bevel gear one, and a drive rod is fixedly inserted into the shaft of the bevel gear two. A drive motor is provided at the end of the drive rod away from the bevel gear two, and the output end of the drive motor is fixedly sleeved with the drive rod through a coupling.

[0014] Preferably, a support step is snapped onto the side of the base near the platform, and a ball bearing is rotatably connected to the side of the support step near the platform, with the ball bearing in contact with the side of the platform near the base.

[0015] In summary, this utility model has the following beneficial effects: 1. With the stable operation of the drive motor, the platform will eventually achieve intermittent transmission operation through the coordinated cooperation of the circular plate and the drive plate. When the shaft rotates one revolution, the drive plate and the rotating rod only complete one-quarter revolution to cooperate with the four workstations arranged around the platform to realize the gradual transmission of workpieces. In turn, in the intermittent transmission mode, each workstation can alternately process the mechanical workpieces, ensuring the continuity of the process connection. 2. During the operation of this tooling, the drive motor always maintains stable and continuous operation without frequent start-stop, which is different from the existing technology that relies on multiple sensors to control the intermittent start of the motor. At the same time, it effectively avoids the wear and tear caused by frequent intermittent operation of the motor on its service life, and eliminates the need for electrical coordination of multiple drive devices and various components. This greatly reduces the tediousness and time cost of repeated debugging work required to achieve coordination, and improves the reliability and economy of the equipment operation. 3. During the use of the interlocking component, the protruding outer surface of the interlocking component and the arc groove are in a mating state. As the interlocking component rotates continuously with the circular plate, it cannot transmit rotational power to the drive plate, thus reliably locking the drive plate. The rotation of the drive plate only occurs during the fitting and engagement stage between the interlocking component and the straight groove, ensuring the accuracy of motion transmission and the reliability of structural operation. With the synergistic effect of the above structures, this tooling structure combines intermittent transmission function with stable self-locking performance. It eliminates the need for an additional dedicated self-locking structure, ensuring stable transmission and reliable operation of the equipment, simplifying structural design while improving operational stability. 4. During the rotation of the platform, the fixtures and workpieces on the surface will be transferred and advanced to different workstations. As the platform rotates synchronously with the rotating rod, the support step surface provides stable support for the platform. At the same time, the rolling characteristics of the balls create a low-friction environment at the contact surface between the two, providing smooth and stable sliding support for the platform's rotation and ensuring the stability and smoothness of the platform's rotation process.

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example

[0020] refer to Figures 1-5 A rotating tooling structure for mechanical automation equipment includes a platform 100, a base 101 is provided on one side of the platform 100, an installation ring 200 is fixedly inserted into the axis on the inner side of the platform 100, and a rotating rod 201 is fixedly inserted into the inner side of the installation ring 200 on the same axis. The end of the rotating rod 201 away from the platform 100 extends into the inner side of the base 101 and is coaxially fixedly fitted with a drive plate 300. The outer side of the drive plate 300 is provided with arc grooves 301 and straight grooves 302 at equal intervals around the circumference, and there are four arc grooves 301 and four straight grooves 302 arranged in an alternating pattern.

[0021] Specifically, under the stable operation of the drive motor 701, the platform 100 will eventually achieve intermittent transmission operation through the coordinated cooperation of the circular plate 400 and the drive plate 300. When the shaft 600 rotates one revolution, the drive plate 300 and the rotating rod 201 only complete one-quarter revolution to cooperate with the four workstations arranged around the platform 100 to realize the gradual transmission of workpieces. In turn, the machine workpieces are processed alternately by each workstation in the intermittent transmission mode, ensuring the continuity of the process connection.

[0022] The rotating rod 201 has a keyway 202 arranged symmetrically at the end away from the base 101, and a mounting key 203 is inserted into the inner side of the keyway 202. The mounting ring 200 has a key cavity 204 arranged symmetrically at the end away from the base 101, and both the keyway 202 and the key cavity 204 are used in conjunction with the mounting key 203. The end of the rotating rod 201 away from the platform 100 is snapped into the axis of the drive plate 300, and the rotating rod 201 is rotatably connected to the base 101 through a bearing.

[0023] Specifically, when assembling the rotating rod 201 and the mounting ring 200, it is necessary to first ensure that the keyway 202 and the key cavity 204 of both are aligned, and then the mounting key 203 is smoothly inserted into the assembly cavity formed by the keyway 202 and the key cavity 204. After the mounting key 203 is inserted, it will generate a squeezing force through its tight fit with the inner wall of the keyway 202 and the key cavity 204, which will act simultaneously on the rotating rod 201 and the mounting ring 200, thereby achieving a stable assembly between the two and ensuring the reliability of the connection structure.

[0024] A circular plate 400 is provided on the side of the drive plate 300 away from the platform 100. A snap-fit ​​member 401 located on the outer side of the drive plate 300 is snapped onto the side of the circular plate 400 near the platform 100. An arc groove 402 is formed on the outer surface of the snap-fit ​​member 401, and the arc groove 402 is used to accommodate and cooperate with the drive plate 300. The outer surface of the snap-fit ​​member 401 is in contact with the arc groove 301. A snap-fit ​​member 500 is snapped onto the side of the circular plate 400 near the platform 100, and the snap-fit ​​member 500 is located on the outer surface of the snap-fit ​​member 401. The snap-fit ​​member 500 is used to snap-fit ​​with the straight groove 302.

[0025] Specifically, when the circular plate 400 and the drive plate 300 are used together, when their assembly relationship is satisfied, the interlocking part 401, except for the protruding outer surface of the second arc groove 402, is embedded in the first arc groove 301, and both are in a centered state. As the circular plate 400 drives the engagement member 401 to rotate synchronously, the locking member 500 also moves circumferentially around the engagement member 401. At this time, the protruding outer surface of the engagement member 401 gradually disengages from the arc groove 301, while the locking member 500 gradually approaches the initial end of the straight groove 302 as the circular plate 400 continues to rotate. Finally, through the matching and engagement of the locking member 500 with the straight groove 302, the movement of the locking member 500 synchronously drives the drive plate 300 to rotate. During the linkage movement of the two, the locking member 500 gradually engages with the end of the straight groove 302 from the initial end to the deep end of the groove.

[0026] Under the gentle and continuous rotation of the circular plate 400, after the snap-fit ​​part 500 enters the end of the straight groove 302, it will gradually move back to the beginning of the straight groove 302. Finally, after the snap-fit ​​part 500 and the straight groove 302 are disengaged, the protruding outer surface of the engagement part 401 will once again precisely engage with the arc groove 301, thus forming a reciprocating motion mechanism. When the engaging member 401 and the arc groove 301 are in a mating state, the engaging member 401 cannot drive the drive plate 300 during the continuous rotation of the circular plate 400, and forms a locked state for the drive plate 300. The rotation of the drive plate 300 only occurs during the engagement stage of the snap-fit ​​member 500 and the straight groove 302, ensuring motion transmission and reliability.

[0027] A shaft 600 is coaxially mounted on the side of the circular plate 400 away from the platform 100, and a bevel gear 601 is mounted on the end of the shaft 600 away from the circular plate 400. A bevel gear 602 meshes with the surface of the bevel gear 601, and a drive rod 700 is fixedly inserted at the axis of the bevel gear 602. A drive motor 701 is provided on the end of the drive rod 700 away from the bevel gear 602, and the output end of the drive motor 701 is fixedly sleeved with the drive rod 700 through a coupling.

[0028] Specifically, after the drive motor 701 starts running, it drives the drive rod 700 and the bevel gear 602 to rotate synchronously. At this time, with the help of the precise meshing transmission characteristics between the gears, the bevel gear 601 and the shaft 600 can be driven to rotate in linkage. The shaft 600 then drives the circular plate 400 to make a stable circumferential rotation, ensuring the continuity and reliability of power transmission.

[0029] A support step 800 is snapped onto the side of the base 101 near the platform 100. A ball bearing 801 is rotatably connected to the side of the support step 800 near the platform 100, and the ball bearing 801 contacts the side of the platform 100 near the base 101.

[0030] Specifically, during the synchronous rotation of platform 100 with rotating rod 201, support step surface 800 provides stable support for platform 100 while forming a low-friction environment on the contact surface of the two by means of the rolling characteristics of ball bearing 801, providing smooth and stable sliding support for the rotation of platform 100, and ensuring the stability and smoothness of the rotation process of platform 100.

[0031] The working principle of this utility model: Under the rotational drive of this tooling structure, the surface of the platform 100 can be assembled with four fixtures that can stably hold the workpiece, and four processing stations with different functions can be arranged around the platform 100 to provide a basic guarantee for the multi-process flow and efficient processing of the workpiece. During the operation of the drive motor 701, the drive rod 700 and the bevel gear 602 rotate synchronously. At this time, with the help of the precise meshing transmission characteristics between the gears, the bevel gear 601 and the shaft 600 can be driven to rotate in linkage. The shaft 600 then drives the circular plate 400 to make a stable circumferential rotation. In the initial state of the circular plate 400, the engaging member 401, except for the protruding outer surface of the second arc groove 402, is embedded in the first arc groove 301. As the circular plate 400 drives the engaging member 401 to rotate synchronously, it simultaneously drives the locking member 500 to form a circumferential movement trend with the engaging member 401 as the axis. At this time, the protruding outer surface of the engaging member 401 gradually disengages from the first arc groove 301, while the locking member 500 gradually approaches the initial end of the straight groove 302 as the circular plate 400 continues to rotate. Finally, through the matching and engagement of the locking member 500 with the straight groove 302, the movement of the locking member 500 synchronously drives the drive plate 300 to rotate. During the linkage movement of the two, the locking member 500 gradually engages with the end of the straight groove 302 from the initial end to the end of the groove.

[0032] Under the gentle and continuous rotation of the circular plate 400, after the snap-fit ​​part 500 enters the end of the straight groove 302, it will gradually move back to the beginning of the straight groove 302. Finally, after the snap-fit ​​part 500 and the straight groove 302 are disengaged, the protruding outer surface of the engagement part 401 will once again precisely engage with the arc groove 301, thus forming a reciprocating motion mechanism. When the engaging member 401 and the arc groove 301 are in a mating state, the engaging member 401 cannot transmit rotational power to the drive plate 300 during the continuous rotation of the circular plate 400, and at the same time forms a reliable lock on the drive plate 300; the rotation of the drive plate 300 only occurs during the matching and engaging stage of the snap-fit ​​member 500 and the straight groove 302, ensuring the accuracy of motion transmission and the reliability of structural operation.

[0033] Through the power transmission of the above structure, the stable operation of the drive motor 701 will drive the platform 100 to eventually achieve intermittent transmission operation. When the shaft 600 rotates one revolution, the drive plate 300 and the rotating rod 201 only complete a quarter revolution to cooperate with the four workstations arranged around the platform 100 to realize the gradual transmission of workpieces, and thus realize the alternating processing of mechanical workpieces by each workstation in the intermittent transmission mode.

[0034] In addition, the drive motor 701 always maintains stable and continuous operation without frequent start-stop, which is different from the intermittent start-up method of motor control by multiple sensors in the existing technology; at the same time, it effectively avoids the wear and tear caused by frequent intermittent operation of the motor on its service life.
