Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts processing technology, specifically relating to a workstation exchange mechanism. Background Technology

[0002] Machinery is a general term for machines and mechanisms. Machinery refers to tools and devices that help people reduce the difficulty of work or save effort. A machine is a combination of man-made physical components, with definite relative motion between its parts. Machines possess the characteristic of being able to replace human labor to perform useful mechanical work or convert mechanical energy. Therefore, from a structural and kinematic point of view, there is no difference between mechanisms and machines; they are collectively referred to as machinery.

[0003] Mechanical parts, also known as mechanical components, are the basic building blocks of machinery and inseparable individual parts that make up machines. Mechanical parts are both a discipline that studies and designs the basic mechanical components in various equipment and a general term for parts and components. Current mechanical parts processing requires multiple steps. Traditional workstation changes are mostly done manually, which is slow, wastes manpower, and poses certain safety hazards. Existing technologies sometimes use workstation changeover mechanisms, which involve two steps: 1. removing the finished workpiece; 2. installing the unfinished workpiece. However, existing workstation changeover mechanisms can only operate individually and cannot perform both steps simultaneously, resulting in generally low efficiency and affecting the actual processing speed. For example, an existing patent document discloses a utility model patent for a station conversion mechanism of a lithium battery casing machine (publication number: CN219144247U). Based on its technical solution and accompanying drawings, it can be seen that the application uses a clamping device in conjunction with a conversion device to transfer the lithium battery from the station for station conversion. However, it is obvious that the clamping device in this application can only achieve a single-step operation. The processed lithium battery must be removed first, and then a new lithium battery must be installed on the station, which also has the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a technical solution for a workstation exchange mechanism to address the shortcomings of existing technologies. The mechanism features a simple and reasonable structural design, strong practicality, small overall size, wide applicability, and convenient operation, ensuring accurate and reliable operation. During workstation exchange, the mechanism enables the simultaneous removal and installation of workpieces, and simultaneously performs synchronous exchange operations on workpieces at two workstations, achieving synchronous one-in-one-out operation of workpieces at two workstations, thereby effectively improving work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The workstation exchange mechanism includes a workstation conversion support, a workstation conversion arm, a first drive component, and a second drive component. A workstation conversion arm shaft is connected to the workstation conversion arm, which is rotatably mounted on the workstation conversion support. The workstation conversion arm has a sliding groove, within which a conversion arm latch is installed, enabling a latching connection with the worktable. The first drive component is connected to the workstation conversion arm shaft, driving its rotation to achieve workstation position switching. The second drive component is connected to the conversion arm latch, driving it to move along the sliding groove. This invention features a simple and reasonable structural design, strong practicality, small overall size, wide applicability, and convenient operation, ensuring precise and reliable operation. During workstation exchange, the mechanism allows for simultaneous workpiece removal and installation, and simultaneous exchange of workpieces between two workstations, enabling synchronized entry and exit of workpieces from both workstations, thereby effectively improving work efficiency.

[0007] Furthermore, the drive component includes a hydraulic motor, a motor gear, and a reduction gear. The hydraulic motor is fixed on the workstation conversion support and is connected to the motor gear. The reduction gear is fixed on the workstation conversion arm shaft and meshes with the motor gear.

[0008] A hydraulic motor drives a geared motor to rotate, which in turn drives a meshing reduction gear to rotate synchronously. The reduction gear then drives the shaft of the station changeover arm, which is fixed to the reduction gear, to rotate synchronously, thus enabling the station changeover arm to switch positions. The structure is ingeniously and rationally designed. The hydraulic motor provides the power source, which, through the geared motor and reduction gears, drives the shaft of the station changeover arm to rotate, thereby rotating the station changeover arm. Furthermore, the geared motor and reduction gears allow the shaft of the station changeover arm to reach a set speed, controlling its rotation speed and making the entire exchange operation smoother and safer.

[0009] Furthermore, the second drive component includes a rotary motor, an inner shaft of the workstation conversion arm, drive gears, and racks. The inner shaft of the workstation conversion arm is rotatably mounted inside the workstation conversion arm shaft. The rotary motor is fixed on the workstation conversion arm shaft. One end of the inner shaft of the workstation conversion arm is connected to the rotary motor, and the other end of the inner shaft of the workstation conversion arm is connected to the drive gears. Two racks are symmetrically and staggered on the workstation conversion arm. Both racks mesh with the drive gears. Conversion arm buckles are fixedly mounted at the far ends of the two racks.

[0010] When the rotary motor drives the drive gear to rotate via the inner shaft of the workstation switching arm, the two racks move in opposite directions, thereby achieving the opposite movement of the two switching arm latches. The rotary motor provides the power source, driving the inner shaft of the workstation switching arm to rotate. The inner shaft of the workstation switching arm drives the drive gear to rotate, and the drive gear drives the two meshing racks to move in opposite directions, thereby achieving the opposite movement of the switching arm latches on the two racks. The switching arm latches then engage with the corresponding worktables, thus realizing the exchange operation of the two worktables through the movement of the two switching arm latches. There are also corresponding workpieces on the worktables. By exchanging the two worktables, the workstation exchange operation between two workpieces can be achieved. The entire operation process is smooth and simple.

[0011] Furthermore, the workstation switching arm is equipped with two pressure strips, forming a sliding groove between the two pressure strips and the workstation switching arm. The two pressure strips correspond to two racks, with each pressure strip restraining and pressing against the side of its corresponding rack. The structure is ingeniously and rationally designed. The pressure strips and the workstation switching arm have pre-drilled holes, allowing for detachable installation with screws. This facilitates the disassembly and maintenance of the internal racks and the switching arm latches. The pressure strips restrain the racks against their sides, and the sliding engagement of the switching arm latches within the sliding groove ensures that the racks can only move along the direction of their corresponding pressure strips. Simultaneously, the racks drive the corresponding switching arm latches to move synchronously along the sliding groove, effectively improving the overall structural stability and reliability after assembly, making the workstation switching process safer and smoother. Oil passages are provided on both sides of the workstation switching arm, allowing for convenient addition of lubricating oil to lubricate the racks.

[0012] Furthermore, a bearing is installed between the inner shaft of the workstation transfer arm and the workstation transfer arm shaft. The bearing is located at both ends of the inner shaft of the workstation transfer arm, and the rotation between the inner shaft and the workstation transfer arm shaft is achieved through the bearing. When the rotary motor starts, it drives the inner shaft of the workstation transfer arm to rotate within the bearing. The bearing arrangement achieves the rotation between the inner shaft and the workstation transfer arm shaft, and also reduces friction and wear between them, which is more conducive to the rotation of the inner shaft of the workstation transfer arm.

[0013] Furthermore, an external thread section is provided at the end of the inner shaft of the workstation conversion arm that is connected to the rotary motor. A workstation conversion arm signal disk one is screwed onto the external thread section. Sensor one and sensor two are provided on the workstation conversion support. Sensor one and sensor two are distributed on the left and right sides of the workstation conversion arm signal disk one.

[0014] When the rotary motor drives the inner shaft of the station changer arm to rotate, the station changer arm signal disk one moves synchronously left and right along the external thread section. The rotary motor drives the inner shaft of the station changer arm to rotate, realizing the opposite or forward movement of the two changer arm latches. Through the cooperation of the station changer arm signal disk one with sensor one and sensor two, it is similar to setting two limit switches. When the station changer arm signal disk one touches sensor one or sensor two, it means that the set limit switch position has been reached, indicating that the corresponding action of the rotary motor is correct and in place. This precisely controls whether the rotary motor action is in place, ensuring that the changer arm latches are in place, thereby improving the smoothness, efficiency and safety of the exchange operation.

[0015] Furthermore, a second signal disk for the workstation switching arm is installed on the outer side of the rotary motor, and a third sensor is installed on the workstation switching support, located directly below the second signal disk. The third sensor is used to detect the signal from the second signal disk. When the workstation switching arm is in its initial vertical position, the third sensor corresponds to the groove on the second signal disk. This arrangement facilitates subsequent control of the rotary motor's reset accuracy, ensuring the correct and timely reset of the hydraulic motor. During the entire workstation exchange process, the rotary motor rotates synchronously with the rotation of the workstation switching arm shaft and the workstation switching arm. The workstation switching arm shaft and the workstation switching arm are driven to rotate by the hydraulic motor. After the entire exchange operation is completed, the hydraulic motor drives the workstation switching arm to rotate and reset, and the rotary motor also rotates and resets synchronously. When the third sensor senses the groove on the second signal disk, it indicates that the rotary motor has reset and the hydraulic motor's reset action has been correct and timely.

[0016] Furthermore, a rotating seat for the workstation transfer arm is installed on the shaft. The rotating seat is keyed to the shaft and secured with a lock nut, effectively ensuring a firm and reliable installation. A motor mount for the workstation transfer arm is fixedly connected to the rotating seat, and the rotary motor is also fixedly mounted on the motor mount. The motor mount and the rotating seat are connected by screws, as are the rotary motor and the motor mount. This design is reasonable, facilitates easy installation and disassembly, and ensures structural stability after assembly.

[0017] Furthermore, a workstation conversion arm signal disk three is fixed on the workstation conversion arm shaft, and a workstation conversion arm signal collector is installed on the workstation conversion support. The workstation conversion arm signal collector is located directly above the workstation conversion arm signal disk three.

[0018] When the workstation changeover arm shaft drives the workstation changeover arm signal disk three to rotate, the workstation changeover arm signal collector senses the changes in the signal teeth on the workstation changeover arm signal disk three. Through the design of the workstation changeover arm signal collector in conjunction with the workstation changeover arm signal disk three, the rotation angle of the workstation changeover arm shaft can be precisely controlled, ensuring the accuracy of the workstation changeover position. Furthermore, the workstation changeover arm is equipped with anti-protrusion blocks, and the workstation changeover support is equipped with limit pins. The limit pins are located on both sides of the workstation changeover arm shaft. The anti-protrusion blocks, in conjunction with the two limit pins, can be used for mechanical limiting in the event of failure of the workstation changeover arm signal disk three or the workstation changeover arm signal collector, preventing excessive rotation of the workstation changeover arm shaft and improving operational safety.

[0019] Furthermore, a second bearing is installed between the workstation transfer arm shaft and the workstation transfer support. The second bearing is located at both ends of the workstation transfer arm shaft, enabling rotation between the shaft and the support. When the hydraulic motor starts, it drives the workstation transfer arm shaft to rotate within the second bearing in the workstation transfer support. This second bearing arrangement reduces friction and wear between the shaft and the support, thus facilitating the workstation transfer operation of the transfer arm.

[0020] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0021] This utility model features a compact design, a simple and reasonable structure, strong practicality, small overall size, wide applicability, and convenient operation. It ensures precise and reliable operation. During workstation exchange, the mechanism allows for simultaneous removal and installation of the workpiece, and also enables synchronous exchange of workpieces at two workstations. The workpieces at the two workstations operate in and out synchronously, thereby effectively improving work efficiency.

[0022] In this invention, a hydraulic motor provides the power source, driving the workstation transfer arm shaft to rotate via motor gears and reduction gears. This, in turn, drives the workstation transfer arm to rotate. The motor gears and reduction gears ensure the workstation transfer arm shaft reaches a set speed. When the workstation transfer arm shaft rotates, all parts fixed to it rotate synchronously. The shaft rotates within the bearing of the workpiece transfer support, ensuring smooth and reliable rotation. Simultaneously, the workstation transfer arm signal disk three, fixed to the shaft, rotates synchronously. As the signal disk three rotates, a workstation transfer arm signal collector fixed to the workstation transfer support senses the signal teeth on the signal disk three, thus determining the rotational position of the workstation transfer arm and ensuring correct and timely operation, improving the accuracy and reliability of each action during the exchange process.

[0023] In the initial state of this invention, the workstation switching arm is set perpendicular to the horizontal plane. Then, the hydraulic motor starts and drives the workstation switching arm to rotate 90° counterclockwise, so that the two switching arm latches on the workstation switching arm are locked into the corresponding two worktables. Each worktable has a workpiece mounted on it. Then, the rotary motor starts and drives the drive gear to rotate. The drive gear drives the two racks to move towards each other. The racks drive the switching arm latches to move towards each other synchronously, thereby dragging the worktables locked with the switching arm latches to the middle of the workstation switching arm. The worktables and workpieces are then disengaged from their corresponding workstations. Then, the hydraulic motor continues to drive the workstation switching arm to rotate 180° clockwise, exchanging the positions of the two worktables. Then, the rotary motor starts and drives the two racks to move in opposite directions. The racks drive the corresponding worktables to move outward through the switching arm latches, exchanging the two worktables and installing them on the other corresponding workstation, realizing the exchange operation between the worktables on the two workstations. Finally, the hydraulic motor drives the workstation switching arm to rotate 90° counterclockwise again, returning it to its original position to await the next exchange operation.

Detailed Implementation

[0035] like Figures 1 to 9 As shown, this utility model's workstation exchange mechanism includes a workstation conversion support 1, a workstation conversion arm 2, a first driving component 6, and a second driving component 7. A workstation conversion arm shaft 3 is connected to the workstation conversion arm 2, and the shaft 3 is rotatably mounted on the workstation conversion support 1. A sliding groove 4 is provided on the workstation conversion arm 2, and a conversion arm latch 5 is installed within the groove 4, enabling a latching connection between the workstation conversion arm 2 and the worktable. The first driving component 6 is connected to the workstation conversion arm shaft 3, driving the shaft 3 to rotate and thus achieving the conversion of the workstation position of the workstation conversion arm 2. The second driving component 7 is connected to the conversion arm latch 5, driving the latch 5 to move along the sliding groove 4. This utility model features a simple and reasonable structural design, strong practicality, small overall size, wide applicability, and convenient operation. It ensures precise and reliable operation, and allows for simultaneous synchronous exchange of workpieces at two workstations, with workpieces entering and exiting synchronously, thereby effectively improving work efficiency.

[0036] The drive component 6 includes a hydraulic motor 8, a motor gear 9, and a reduction gear 10. The hydraulic motor 8 is fixed on the workstation conversion support 1 and connected to the motor gear 9. The reduction gear 10 is fixed on the workstation conversion arm shaft 3, and the motor gear 9 and reduction gear 10 mesh. The hydraulic motor 8 drives the motor gear 9 to rotate, which in turn drives the meshed reduction gear 10 to rotate synchronously. The reduction gear 10 then drives the workstation conversion arm shaft 3 to rotate synchronously, thus realizing the conversion of the workstation on the workstation conversion arm 2. The structural design is ingenious and reasonable. The hydraulic motor 8 provides the power source, which drives the workstation conversion arm shaft 3 to rotate through the motor gear 9 and reduction gear 10, thereby driving the workstation conversion arm 2 to rotate. Furthermore, the motor gear 9 and reduction gear 10 enable the workstation conversion arm shaft 3 to reach a set speed, controlling the rotation speed of the workstation conversion arm shaft 3, making the entire exchange operation process smoother and safer.

[0037] Drive component 2 7 includes a rotary motor 11, an inner shaft 12 of a workstation conversion arm, a drive gear 13, and a rack 14. The inner shaft 12 of the workstation conversion arm is rotatably mounted inside the workstation conversion arm shaft 3. The rotary motor 11 is fixed on the workstation conversion arm shaft 3. One end of the inner shaft 12 of the workstation conversion arm is connected to the rotary motor 11, and the other end of the inner shaft 12 of the workstation conversion arm is connected to the drive gear 13. Two racks 14 are symmetrically and staggered on the workstation conversion arm 2. Both racks 14 mesh with the drive gear 13. A conversion arm buckle 5 is fixedly mounted at the far ends of the two racks 14.

[0038] When the rotary motor 11 drives the drive gear 13 to rotate via the inner shaft 12 of the station conversion arm, the two racks 14 move in opposite directions, thereby realizing the opposite movement of the two conversion arm latches 5. The rotary motor 11 provides the power source, driving the inner shaft 12 of the station conversion arm to rotate. The inner shaft 12 of the station conversion arm drives the drive gear 13 to rotate, and the drive gear 13 drives the two meshing racks 14 to move in opposite directions, thereby realizing the opposite movement of the conversion arm latches 5 on the two racks 14. The conversion arm latches 5 are then engaged with the corresponding worktables, thus realizing the exchange operation of the two worktables through the movement of the two conversion arm latches 5. There are also corresponding workpieces on the worktables. By exchanging the two worktables, the station exchange operation between the two workpieces can be realized. The whole operation process is smooth and simple.

[0039] The workstation switching arm 2 is equipped with two pressure strips 15, forming a sliding groove 4 between the two pressure strips 15 and the workstation switching arm 2. The two pressure strips 15 correspond to two racks 14, with each pressure strip 15 limiting and pressing against the side of its corresponding rack 14. The structure is cleverly and rationally designed. The pressure strips 15 and the workstation switching arm 2 have pre-drilled holes, allowing for detachable installation with screws. This facilitates the disassembly and maintenance of the internal racks 14 and the switching arm latch 5. The pressure strips 15 limit and press against the side of their respective racks 14, and the sliding engagement of the switching arm latch 5 within the sliding groove 4 ensures that the racks 14 can only move along the direction of their corresponding pressure strips 15. Simultaneously, the racks 14 drive the corresponding switching arm latch 5 to move synchronously along the sliding groove 4, effectively improving the overall structural stability and reliability after assembly, making the workstation exchange process safer and smoother. Oil passages are provided on both sides of the workstation switching arm 2, allowing for convenient addition of lubricating oil to lubricate the racks 14.

[0040] A bearing 16 is installed between the inner shaft 12 and the shaft 3 of the workstation transfer arm. The bearing 16 is located at both ends of the inner shaft 12, and the rotation between the inner shaft 12 and the shaft 3 is achieved through the bearing 16. When the rotary motor 11 is started, it drives the inner shaft 12 of the workstation transfer arm to rotate within the bearing 16 on the shaft 3. The bearing 16 enables the rotation between the inner shaft 12 and the shaft 3, reduces friction and wear between them, and is more conducive to the rotation of the inner shaft 12.

[0041] An external thread section 17 is provided at the end of the inner shaft 12 of the workstation conversion arm that is connected to the rotary motor 11. A workstation conversion arm signal disk 18 is screwed onto the external thread section 17. A sensor 19 and a sensor 20 are provided on the workstation conversion support 1. The sensor 19 and the sensor 20 are distributed on the left and right sides of the workstation conversion arm signal disk 18. When the rotary motor 11 drives the inner shaft 12 of the workstation conversion arm to rotate, the workstation conversion arm signal disk 18 moves synchronously left and right along the external thread section 17. The rotary motor 11 drives the inner shaft 12 of the station conversion arm to rotate, realizing the opposite or forward movement of the two conversion arm latches 5. Through the cooperation of the station conversion arm signal disk 18 and the sensors 19 and 20, it is similar to setting two limit switches. When the station conversion arm signal disk 18 touches the sensor 19 or the sensor 20, it means that the set limit switch position has been reached, which indicates that the corresponding action of the rotary motor 11 is correct and in place. This accurately controls whether the action of the rotary motor 11 is in place, ensuring that the conversion arm latches 5 are moved into place, thereby improving the smoothness, efficiency and safety of the exchange operation.

[0042] A position switching arm signal disk 21 is provided on the outer side of the rotary motor 11, and a sensor 22 is provided on the position switching support 1. The sensor 22 is located directly below the position switching arm signal disk 21. The sensor 22 is used to detect the signal from the position switching arm signal disk 21. When the position switching arm 2 is in its initial vertical position, the sensor 22 corresponds to the groove on the position switching arm signal disk 21. This arrangement facilitates the subsequent control of the accuracy of the rotary motor 11's reset and ensures the correct reset action of the hydraulic motor 8. During the entire station exchange process, the rotary motor 11 rotates synchronously with the rotation of the station conversion arm shaft 3 and the station conversion arm 2. The station conversion arm shaft 3 and the station conversion arm 2 are driven to rotate by the hydraulic motor 8. After the entire exchange operation is completed, the hydraulic motor 8 drives the station conversion arm 2 to rotate and reset, and at the same time, the rotary motor 11 also rotates and resets synchronously. When the sensor 3 22 senses the groove on the station conversion arm signal disk 21, it indicates that the rotary motor 11 has reset in place, and the hydraulic motor 8 has correctly completed its reset action. Sensors 1 19, 20, and 3 22 are all mounted on an auxiliary frame 30, which is fixedly connected to the station conversion support 1. The design is reasonable and effectively ensures the secure installation of the sensors.

[0043] A station conversion arm rotating seat 23 is provided on the station conversion arm shaft 3. The station conversion arm rotating seat 23 is connected to the station conversion arm shaft 3 by a key, and the station conversion arm rotating seat 23 is locked and fixed to the station conversion arm shaft 3 by a locking nut 24, which effectively ensures the installation is firm and reliable. A station conversion arm motor seat 25 is fixedly connected to the station conversion arm rotating seat 23, and the rotary motor 11 is fixedly installed on the station conversion arm motor seat 25. The motor base 25 of the workstation conversion arm has a slot to facilitate the installation of the workstation conversion arm signal disk 18 and the motor base 25. A guide rod is also installed in the slot, which passes through the workstation conversion arm signal disk 18. The guide rod can also assist in guiding and limiting the movement of the workstation conversion arm signal disk 18, making the movement of the workstation conversion arm signal disk 18 more stable and reliable. The motor base 25 of the workstation conversion arm is fixedly connected to the workstation conversion arm rotating seat 23 with screws, and the rotary motor 11 is also fixedly connected to the motor base 25 of the workstation conversion arm with screws. The design is reasonable, the installation and disassembly are convenient and simple, and the structural stability after assembly is guaranteed.

[0044] A signal disk 26 for the workstation switching arm is fixed on the shaft 3, and a signal collector 27 for the workstation switching arm is installed on the workstation switching support 1, located directly above the signal disk 26. When the shaft 3 drives the signal disk 26 to rotate, the signal collector 27 senses the change in the signal teeth 28 on the signal disk 26. Through the design of the signal collector 27 and the signal disk 26, the rotation angle of the shaft 3 can be precisely controlled, ensuring the accuracy of the workstation switching position of the workstation switching arm 2. Furthermore, the workstation conversion arm 2 is equipped with abutment 32, and the workstation conversion support 1 is equipped with limit pins 31. The limit pins 31 are located on both sides of the workstation conversion arm shaft 3. The design of the abutment 32 in conjunction with the two limit pins 31 can be used for mechanical limiting after the failure of the workstation conversion arm signal disk 3 26 and the workstation conversion arm signal collector 27, to prevent the workstation conversion arm shaft 3 from rotating excessively and to improve operational safety.

[0045] A second bearing 29 is installed between the workstation transfer arm shaft 3 and the workstation transfer support 1. The second bearing 29 is distributed at both ends of the workstation transfer arm shaft 3, and the rotation between the workstation transfer arm shaft 3 and the workstation transfer support 1 is achieved through the second bearing 29. When the hydraulic motor 8 is started, it drives the workstation transfer arm shaft 3 to rotate in the second bearing 29 within the workstation transfer support 1. The installation of the second bearing 29 enables the rotation between the workstation transfer arm shaft 3 and the workstation transfer support 1, reduces friction and wear between the two, and thus facilitates the workstation transfer operation of the workstation transfer arm 2.

[0046] This utility model features a compact design, a simple and reasonable structure, strong practicality, small overall size, wide applicability, and convenient operation. It ensures accurate and reliable operation and allows for simultaneous exchange of workpieces at two workstations, enabling synchronized entry and exit of workpieces from both workstations, thereby effectively improving work efficiency.

[0047] In this invention, the hydraulic motor 8 provides the power source, driving the workstation switching arm shaft 3 to rotate via the motor gear 9 and the reduction gear 10, which in turn drives the workstation switching arm 2 to rotate. The motor gear 9 and the reduction gear 10 ensure that the workstation switching arm shaft 3 reaches a set speed. When the workstation switching arm shaft 3 rotates, all parts fixed on it rotate synchronously. The workstation switching arm shaft 3 rotates within the bearing 29 of the workpiece switching support, ensuring smooth and reliable rotation. Simultaneously, the workstation switching arm signal disk 26 fixed on the workstation switching arm shaft 3 rotates synchronously. When the workstation switching arm signal disk 26 rotates, the workstation switching arm signal collector 27 fixed on the workstation switching support 1 simultaneously senses the signal teeth 28 on the workstation switching arm signal disk 26, thereby knowing the rotational position of the workstation switching arm 2, ensuring correct and timely operation, and improving the accuracy and reliability of each action during the exchange operation.

[0048] In the initial state of this invention, the workstation conversion arm 2 is set perpendicular to the horizontal plane. Then, the hydraulic motor 8 starts and drives the workstation conversion arm 2 to rotate counterclockwise by 90°, so that the two conversion arm latches 5 on the workstation conversion arm 2 are precisely engaged with the corresponding two worktables. Each worktable has a workpiece mounted on it. Then, the rotary motor 11 starts and drives the drive gear 13 to rotate. The drive gear 13 drives the two racks 14 to move towards each other. The racks 14 drive the conversion arm latches 5 to move towards each other synchronously, thereby dragging the worktable engaged with the conversion arm latches 5 to the center of the workstation conversion arm 2. In between, the worktable moves the workpiece away from the corresponding workstation. Then, the hydraulic motor 8 drives the workstation switching arm 2 to rotate 180° clockwise, exchanging the positions of the two worktables. Then, the rotary motor 11 is started to drive the two racks 14 to move in opposite directions. The racks 14 drive the corresponding worktable to move outward through the switching arm latch 5, exchanging the two worktables and installing them on the corresponding other workstation, realizing the exchange operation between the worktables on the two workstations. Finally, the hydraulic motor 8 drives the workstation switching arm 2 to rotate 90° counterclockwise, returning to the original position to wait for the next exchange operation.
