Description

Technical Field

[0001] This utility model relates to the field of workstation rotation switching technology, and in particular to a novel workstation rotation switching mechanism. Background Technology

[0002] With the rapid development of industrial automation technology, multi-station equipment is increasingly widely used in assembly, testing, and processing. Therefore, a station rotation switching mechanism is needed, which is a device used to rotate and switch between different stations. It can be driven by a motor, cylinder or other power source to rotate and switch workpieces or tooling fixtures between multiple stations, thereby improving production efficiency, reducing labor costs and enhancing production flexibility.

[0003] Traditional multi-station switching solutions suffer from problems such as bulky structure (relying on complex gear sets for drive, occupying a large space and being difficult to maintain), low switching efficiency (the linear slide needs to reciprocate, increasing cycle time for each switch), and poor positioning accuracy (the servo turntable is easily affected by inertia, causing tool position deviation, requiring repeated calibration). Utility Model Content

[0004] The main objective of this invention is to provide a novel workstation rotation switching mechanism that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel station rotation switching mechanism includes a servo motor and a mounting frame. A planetary reducer is fixedly mounted on the output end of the servo motor, and a pulley is fixedly mounted on the output shaft of the planetary reducer. The planetary reducer is fixedly mounted on the lower end of the mounting frame. A pushing mechanism is fixedly mounted on the upper right side of the mounting frame, and a guide block is fixedly mounted on the left end of the pushing mechanism. Two mounting plates are fixedly mounted on the upper left side of the mounting frame. Each mounting plate is provided with a rotating bearing. A turntable is rotatably mounted between the two rotating bearings. A synchronous belt is mounted on the outer surface of the turntable and the pulley. Several stations are mounted on the turntable. Self-lubricating graphite copper sleeves are embedded in several stations, and actuator push rods are inserted into several self-lubricating graphite copper sleeves.

[0007] In this application, all electrical equipment is connected to an external controller, which controls the drive. A servo motor drives a synchronous belt, and the servo motor is connected to a planetary reducer to improve inertia and torque. The synchronous belt then precisely drives the turntable, allowing for rapid switching of work positions through rotation. In addition, the push mechanism is controlled by a servo system, using an actuator motor to drive a lead screw for feed motion. When the push mechanism moves forward and pushes out the actuator push rod, the actuator push rod slides axially within a self-lubricating graphite copper sleeve, thereby performing tube end processing.

[0008] Preferably, the T-shaped boss at the tail of the actuator is engaged in the T-shaped slot of the guide block, the head of the actuator is fixedly connected to the forming mold, and the actuator slides axially on the self-lubricating graphite copper sleeve.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. A servo motor drives a synchronous belt, which is connected to a planetary reducer to increase inertia and torque. The synchronous belt then precisely drives the turntable, allowing for rapid switching of workstations via rotation. The push mechanism is controlled by a servo system, using an actuator motor to drive a lead screw for feed motion. The push mechanism is fixed to a mounting frame, with the lead screw's front end connected to a guide block. Compared to existing technologies using hydraulic cylinders for feed, which only stop at a fixed position, offering limited compatibility and making product changes more complex, this solution ensures consistent feed direction and allows for precise stopping at any position, requiring only parameter adjustments. This significantly improves compatibility and conversion efficiency. When the push mechanism moves forward, pushing the actuator rod out, the actuator rod slides axially within a self-lubricating graphite copper sleeve, thus performing tube end processing. Therefore, this solution uses rotation to switch workstations, resulting in a simple, reliable, and rapid switching mechanism that greatly reduces production costs and increases production efficiency. Furthermore, the propulsion distance can be arbitrarily controlled within the stroke. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1 As shown, a novel station rotation switching mechanism includes a servo motor 1 and a mounting frame 11. A planetary reducer 2 is fixedly mounted on the output end of the servo motor 1. A pulley is fixedly mounted on the output shaft of the planetary reducer 2. The planetary reducer 2 is fixedly mounted on the lower end of the mounting frame 11. A pushing mechanism 4 is fixedly mounted on the upper right side of the mounting frame 11. A guide block 5 is fixedly mounted on the left end of the pushing mechanism 4. Two mounting plates are fixedly mounted on the upper left side of the mounting frame 11. Rotary bearings 8 are provided on both mounting plates. A turntable 7 is rotatably mounted between the two rotary bearings 8. A synchronous belt 3 is mounted on the outer surface of the turntable 7 and the pulley. Several stations are mounted on the turntable 7. Self-lubricating graphite copper sleeves 10 are embedded in several stations. An execution push rod 6 is inserted into each of the self-lubricating graphite copper sleeves 10. The T-shaped boss at the tail of the execution push rod 6 is inserted into the T-shaped slot of the guide block 5. The head of the execution push rod 6 is fixedly connected to the forming mold 9. The execution push rod 6 slides axially on the self-lubricating graphite copper sleeve 10.

[0017] In this application, all electrical equipment is connected to an external controller, which controls the drive. The servo motor 1 drives the synchronous belt 3, and the servo motor 1 is connected to the planetary reducer 2 to improve inertia and torque. At this time, the synchronous belt 3 precisely drives the turntable 7, thereby quickly switching work positions by rotation. In addition, the push mechanism 4 is controlled by the servo system and uses the actuator motor to drive the lead screw for feed motion. When the push mechanism 4 moves forward and pushes out the actuator push rod 6, the actuator push rod 6 slides axially within the self-lubricating graphite copper sleeve 10, thereby performing tube end processing.

[0018] It should be noted that this utility model is a novel workstation rotation switching mechanism. A servo motor 1 drives a synchronous belt 3, and the servo motor 1 is connected to a planetary reducer 2 to improve inertia and torque. The synchronous belt 3 then precisely drives the turntable 7, thereby quickly switching workstations through rotation. Furthermore, the pushing mechanism 4 is controlled by a servo system, using an actuator motor to drive a lead screw for feed motion. The pushing mechanism 4 is fixed on the mounting bracket 11, and the front end of the lead screw is connected to a guide block 5. Compared to existing technologies that use hydraulic cylinders for feed, which only have one fixed position... The previous solution had limited compatibility and was more complex and cumbersome when changing product types. This solution ensures the consistency of the feed direction and can achieve precise stopping at any position. Only parameter adjustments are needed, which greatly improves compatibility and conversion efficiency. When the pushing mechanism 4 moves forward to push out the actuator 6, the actuator 6 slides axially within the self-lubricating graphite copper sleeve 10 to perform tube end processing. Therefore, this solution switches workstations by rotation. The structure is simple and reliable, and the switching is rapid, which greatly reduces production costs and improves production efficiency. Moreover, the propulsion method allows for arbitrary control of the distance within the stroke.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
