Description

Technical Field

[0001] The invention belongs to the technical field of welding processing equipment, and in particular relates to a method for using a body reinforcement and flipping device for an electric tricycle. Background Art

[0002] An electric tricycle is a three-wheeled transport vehicle powered by a battery and driven by an electric motor for hauling goods or people. It is highly adaptable, maneuverable, simple to maintain, easy to repair, and inexpensive. It can flexibly travel through ports and docks and is widely used in transporting fish, marine research, and rescue missions. In the maintenance and upkeep of marine facilities, the body of the electric tricycle is an important component, which not only bears the weight of the vehicle, but also affects the appearance, safety, and comfort of the vehicle. The body of an electric tricycle is generally composed of a frame, a rear bucket, a front fork, a seat, front and rear wheels, etc., which support the entire vehicle. In addition, the body also includes a carriage and a shell. During the processing of the carriage and frame, welding reinforcement ribs are used to improve the overall structural strength of the body.

[0003] In the production process of electric tricycles, the flipping equipment is mainly used for flipping operations on the body, frame and other parts of the electric tricycle to facilitate the smooth progress of production processes such as welding, assembly and testing.

[0004] The authorization publication number "CN118650368B" records "an electric tricycle body reinforcement flipping device, including a welded plate, a flipping table is arranged below the welded plate, and rotating devices are symmetrically arranged on the left and right sides of the inner wall of the flipping table, and the flipping table includes an upper plate, and the left and right sides of the upper plate are slidably connected to side slides through bridging slides, and the lower surface of the side slide is fixedly connected to a lower slide. When flipping, the center of gravity of the welded plate is bound to shift. When the clamping force remains unchanged, the extrusion clamp clamping the welded plate is prone to slipping with the welded plate, and the veneer tension plate can push the clamping parts on both sides away, and the extrusion clamp clamps the inner wall of the welded plate while extruding and contacting with the side parts of the welded plate, so that there is no reserved space for slipping between the welded plate and the extrusion clamp, thereby ensuring the stability of the welded plate."

[0005] The above patent uses a torque turntable to freely flip the welding plate, so that the operator can freely process the outer surface of the welding plate. Since the welding plate is a symmetrical structure, the center of gravity of the welding plate will inevitably shift when flipping. When the clamping force remains unchanged, the extrusion clamp clamping the welding plate is prone to slipping with the welding plate. The veneer tension plate can push the clamping parts on both sides away, and the extrusion clamp clamps the inner wall of the welding plate while extruding and contacting with the side of the welding plate, so that there is no reserved space for slipping between the welding plate and the extrusion clamp, thereby ensuring the stability of the welding plate. However, when welding the frame and reinforcement ribs and other frame structures to the bottom of the plate, it is impossible to manually clamp and fix the frame and reinforcement ribs and other frame structures, resulting in the reliance on welders to manually fix the frame and reinforcement ribs and other frame structures, resulting in an increase in the welding workload of the welders, and ultimately reducing the processing efficiency of the electric tricycle body. For this reason, we propose a method for using an electric tricycle body reinforcement flipping device. Summary of the invention

[0015] As a preferred solution of the present invention, a gyroscope is fixedly connected to the bottom of the soldering table, and a camera is fixedly connected to the inner wall of the frame. The camera corresponds to the receiving groove.

[0016] A method for using an electric tricycle body strengthening and flipping device includes the following steps: S1. Magnetic adsorption feeding: When the pawl is engaged with the ratchet to lock the deflection of the soldering table, so that the soldering table is in a horizontal state, the bottom of the vehicle board is placed upward in the receiving groove, and a plurality of electromagnetic blocks are energized to magnetically fix the bottom of the vehicle board. At the same time, the frame structure to be welded is placed at the position on the vehicle board as required, realizing magnetic adsorption feeding before welding operation. S2. Automatic clamping: After magnetically adsorbing and feeding the vehicle board and the frame structure, the second motor is energized to start. The output end of the second motor drives the second driving gear to rotate. The second driving gear drives the second driven gear to rotate through meshing with the second driven gear. The second driven gear drives the lead screw to rotate. The lead screw pushes a plurality of electric telescopic rods and the pressing plate to reciprocate on the vehicle board and the frame structure through sliding cooperation with the U-shaped frame. At the same time, the limiting block ensures the stable reciprocating movement of the pressing plate through sliding cooperation with the limiting groove and the sliding cooperation between the U-shaped frame and the lead screw. When the camera collects image data and judges that the pressing plate is located at the horizontal center position of the frame structure, a plurality of electric telescopic rods are energized to start, so that the output ends of the plurality of electric telescopic rods extend downward to press the pressing plate. The pressed pressing plate clamps and fixes the frame structure on the upper side of the vehicle board. Then, the plurality of electromagnetic blocks are powered off and demagnetized to release the magnetic adsorption fixation of the vehicle board, completing the automatic clamping of the frame structure. S3. Inclined welding: After the frame structure is automatically clamped, the electric push rod is powered on and started. The output end of the electric push rod contracts to move the adapter block. The adapter block pulls the pawl to deflect away from the ratchet wheel, releasing the clamping and locking of the pawl and the ratchet wheel, so that the rotating shaft, the soldering station, the vehicle board and the frame structure can deflect. Then the first motor is powered on and started. The output end of the first motor drives the first driving gear to rotate. The first driving gear drives the first driven gear to rotate through meshing with the first driven gear. The first driven gear drives the rotating shaft to rotate. The rotating shaft drives the soldering station, the vehicle board and the frame structure to tilt, offsetting the vertical gravity generated by the two eccentric blocks. Finally, the output end of the electric push rod extends to push the adapter block. The adapter block pushes the pawl and the ratchet wheel to be clamped and locked, and the rotating shaft and the soldering station rotate, facilitating the welder to weld between the vehicle board and the frame structure, and then realizing the inclined welding of the vehicle board and the frame structure. S4. Quick reset: After the inclined welding is completed, the electric push rod is powered on and started. The output end of the electric push rod contracts to pull the adapter block. The adapter block pulls the pawl away from the ratchet wheel, releasing the clamping and locking of the pawl and the ratchet wheel. The two eccentric blocks are reset in the two deflection grooves. Using the vertical gravity generated by the two eccentric blocks, the rotating shaft, the soldering station, the vehicle board and the frame structure are reset to the horizontal state. Then the output end of the electric push rod extends, causing the pawl and the ratchet wheel to be locked, restricting the deflection of the vehicle board and the frame structure, and realizing the quick reset of the vehicle board and the frame structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this solution, during the process of clamping the frame structure, the driving assembly drives the lead screw to rotate. The lead screw pushes the U-shaped frame to reciprocate above the vehicle board and the frame structure through the sliding fit with the U-shaped frame, and then drives the reciprocating movement of the pressing plate. When the pressing plate is at the top center of the frame structure, multiple electric telescopic rods are powered on and started. The output ends of the multiple electric telescopic rods extend to press down the frame structure, clamping and fixing the frame structure at the bottom of the vehicle board. Through the automatic clamping between the vehicle board and the frame structure, it replaces the welder's auxiliary clamping and movement of the frame structure, thereby reducing the workload of the welder, shortening the welding operation time when increasing the strength of the electric tricycle body, and effectively improving the processing efficiency of the electric tricycle body.

[0018] In this solution, the guide rod stably guides the movement of the U-shaped frame through the sliding fit with the U-shaped frame. The limiting groove is opened to accommodate the limiting block. The limiting block ensures the stable movement of the U-shaped frame through the sliding fit with the limiting groove, and then effectively controls the smoothness of the reciprocating movement of the U-shaped frame, the pressing plate and the multiple electric telescopic rods, avoiding the vibration generated during the movement of the pressing plate to cause a slight offset of the frame structure, effectively improving the welding precision between the frame structure and the vehicle board, and increasing the finished product rate of the semi-finished electric tricycle body assisted by the flipping device for welding.

[0019] In this solution, during the flipping process of the vehicle board and the frame structure, the first motor is powered on to start the first driving gear. The first driving gear drives the first driven gear to rotate through meshing with the first driven gear. The first driven gear drives the rotating shaft and the welding table to deflect, thereby tilting the vehicle board and the frame structure, making the vehicle board and the frame structure in a reasonable tilted state, expanding the welding operation space for the welder, facilitating the welder to step on the vehicle board with one foot, and enabling the welder to perform the welding operation between the vehicle board and the frame structure in a suitable and comfortable welding manner, reducing the difficulty of the welding operation.

[0020] In this solution, when it is necessary to release the rotational locking of the rotating shaft, the output end of the electric push rod contracts to pull the adapter block, and the adapter block pulls the pawl away from the ratchet, thereby releasing the engagement between the pawl and the ratchet and eliminating the rotational locking of the rotating shaft. When it is necessary to lock the rotation of the rotating shaft, the electric push rod is powered on and started. The output end of the electric push rod extends to push the adapter block, and the adapter block pushes the pawl close to the ratchet. Then, the pawl and the ratchet engage to lock the rotation of the rotating shaft. By deflecting the pawl, the state between the pawl and the ratchet is controlled, effectively controlling whether the rotating shaft can rotate, and then controlling the tilting angle of the locked vehicle board and the frame structure to adapt to the welding requirements of vehicle boards and frames with different specifications and volumes, improving the application range and practicability of the electric tricycle body strengthening flipping device.

[0039] In the present invention, the two deflection grooves 11 are used to accommodate the swinging of the two eccentric blocks 12. The two eccentric blocks 12 fall due to the gravity generated by their own weights, keeping the rotating shaft 6 and the welding table 2 in a horizontal state. At the same time, after the inclined welding is completed, the vertical gravity generated by the two eccentric blocks 12 is used to reset the rotating shaft 6, the welding table 2, the car body and the frame structure to a horizontal state. Then, the output end of the electric push rod 17 extends, so that the pawl 15 is stuck with the ratchet 14, restricting the deflection of the car body and the frame structure, and realizing the rapid reset of the car body and the frame structure.

[0040] A gyroscope 18 is fixedly connected to the bottom of the welding table 2, and a camera 4 is fixedly connected to the inner wall of the frame 1. The camera 4 corresponds to the receiving groove 5.

[0041] In the present invention, the gyroscope 18 is used to detect the inclination angle of the car body and the frame structure in real time, trigger the extension of the output end of the electric push rod 17, so that the pawl 15 engages with the ratchet 14, and accurately incline the car body and the frame structure. The camera 4 is used to photograph the position of the frame structure at the bottom of the car body, collect the position data between the car body and the frame structure, and provide an accurate position data reference for the movement of the pressing plate 24.

[0042] A usage method of an electric tricycle body strengthening and flipping device includes the following steps: S1. Magnetic adsorption feeding: When the pawl 15 engages with the ratchet wheel 14 to lock and prevent the deflection of the soldering station 2, the soldering station 2 is in a horizontal state. The bottom of the vehicle board is placed upward in the receiving groove 5, and power is supplied to start multiple electromagnetic blocks 3 to magnetically fix the bottom of the vehicle board. At the same time, the frame structure to be welded is placed at the position on the vehicle board as required to achieve magnetic loading before the welding operation; S2. Automatic clamping: After magnetically loading the vehicle board and the frame structure, power is supplied to start the second motor 30. The output end of the second motor 30 drives the second driving gear 26 to rotate. The second driving gear 26 drives the second driven gear 25 to rotate through meshing with the second driven gear 25. The second driven gear 25 drives the lead screw 21 to rotate. The lead screw 21 pushes multiple electric telescopic rods 23 and the pressing plate 24 to reciprocate on the vehicle board and the frame structure through sliding cooperation with the U-shaped frame 22. At the same time, the limiting block 28 ensures the smooth reciprocating movement of the pressing plate 24 through sliding cooperation with the limiting groove 29 and the sliding cooperation between the U-shaped frame 22 and the lead screw 21. When the camera 4 collects image data and determines that the pressing plate 24 is located at the horizontal center position of the frame structure, power is supplied to start multiple electric telescopic rods 23, so that the output ends of the multiple electric telescopic rods 23 extend downward to press the pressing plate 24. The pressed pressing plate 24 clamps and fixes the frame structure on the upper side of the vehicle board. Then, the multiple electromagnetic blocks 3 are powered off and demagnetized to release the magnetic fixation of the vehicle board, completing the automatic clamping of the frame structure; S3. Inclined welding: After automatically clamping the frame structure, power is supplied to start the electric push rod 17. The output end of the electric push rod 17 contracts to move the adapter block 16. The adapter block 16 pulls the pawl 15 to deflect away from the ratchet wheel 14, releasing the engagement and locking between the pawl 15 and the ratchet wheel 14, so that the rotating shaft 6, the soldering station 2, the vehicle board and the frame structure can deflect. Then, power is supplied to start the first motor 10. The output end of the first motor 10 drives the first driving gear 9 to rotate. The first driving gear 9 drives the first driven gear 8 to rotate through meshing with the first driven gear 8. The first driven gear 8 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the soldering station 2, the vehicle board and the frame structure to incline, offsetting the vertical gravity generated by the two eccentric blocks 12. Finally, the output end of the electric push rod 17 extends to push the adapter block 16. The adapter block 16 pushes the pawl 15 to engage and lock with the ratchet wheel 14 to rotate the rotating shaft 6 and the soldering station 2, facilitating the welder to weld between the vehicle board and the frame structure, and then realizing the inclined welding of the vehicle board and the frame structure; S4. Quick reset: After the inclined welding is completed, the electric push rod 17 is powered on and started. The output end of the electric push rod 17 contracts to pull the adapter block 16, and the adapter block 16 pulls the pawl 15 away from the ratchet wheel 14, releasing the clamping and locking of the pawl 15 and the ratchet wheel 14. The two eccentric blocks 12 are reset in the two deflection grooves 11. By using the vertical gravity generated by the two eccentric blocks 12, the rotating shaft 6, the soldering table 2, the vehicle board and the frame structure are reset to a horizontal state. Then, the output end of the electric push rod 17 extends, causing the pawl 15 and the ratchet wheel 14 to be locked, restricting the deflection of the vehicle board and the frame structure, and realizing the rapid reset of the vehicle board and the frame structure.
