Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a flipping mechanism for flipping large sheet metal parts in machining. Background Technology

[0002] In the production of automobiles and construction machinery, large sheet metal parts often need to be processed (e.g., welded). To ensure welding quality, it is necessary to flip the sheet metal parts during the welding process to obtain the ideal welding angle, as different welding processes have specific requirements for the welding angle. At the same time, to improve welding efficiency, it is also necessary to flip the sheet metal parts during the welding process. Flipping the sheet metal parts can expose the welding area for easy welding by welders, or expose multiple welding areas simultaneously, supporting multiple welders to weld at the same time, which can shorten the overall production cycle.

[0003] Currently, the production line uses manual operation of clamping and lifting devices to hold the sheet metal products. The sheet metal products and lifting devices are then lifted to a certain height by a cantilever crane, and the sheet metal products are then manually flipped. This method of flipping sheet metal products not only has low production efficiency, high labor intensity, high production costs, and large production space occupation, but also poses safety hazards. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a new type of 180-degree flipping mechanism for large sheet metal parts, which can automatically clamp and flip large sheet metal parts, effectively reducing manual labor intensity and improving production efficiency.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a novel 180-degree flipping mechanism for large sheet metal parts, including a base, a motor, and a reducer. The motor is mounted on the upper surface of one side of the base, and the motor output end is connected to the reducer. It also includes a support assembly, a transmission assembly, and a flipping assembly. The support assembly includes a first bracket and a second bracket, which are mounted side-by-side on the upper surface of the base. The transmission assembly includes a first transmission shaft, a first coupling, a first pinion, a second transmission shaft, a second coupling, and a second pinion. The first transmission shaft is mounted on the first bracket via bearings, and the first pinion is mounted on the first transmission shaft. The right end of the first transmission shaft is connected to the reducer via the first coupling, and the second transmission shaft is mounted on the second bracket via bearings. On frame two, pinion two is mounted on drive shaft two, and the left end of drive shaft one is connected to drive shaft two via coupling two; the tilting assembly includes rotating shaft one, large gear one, connecting plate one, rotating shaft two, large gear two, connecting plate two, and material support frame. Rotating shaft one is mounted on support one via bearings. Large gear one is mounted on rotating shaft one and meshes with pinion one. One end of connecting plate one is connected to the end face of large gear one, and the other end of connecting plate one extends outward and connects to the material support frame. Rotating shaft two is mounted on support two via bearings. Large gear two is mounted on rotating shaft two and meshes with pinion two. One end of connecting plate two is connected to the end face of large gear two, and the other end of connecting plate two extends outward and connects to the material support frame.

[0006] A further technical solution of this utility model is as follows: the first rotating shaft is located directly above the first transmission shaft, the first large gear is located directly above the first small gear, and the two end faces of the first large gear are respectively connected to the first connecting plate, and the ends of the two connecting plates away from the first large gear are respectively connected to the right swing arm of the material support frame through connecting devices; the second rotating shaft is located directly above the second transmission shaft, the second large gear is located directly above the second small gear, and the two end faces of the second large gear are respectively connected to the second connecting plate, and the ends of the two connecting plates away from the second large gear are respectively connected to the left swing arm of the material support frame through connecting devices.

[0007] A further technical solution of this utility model is: the front end and the rear end of the material support frame are respectively provided with automatic clamping mechanisms capable of clamping large sheet metal parts.

[0008] A further technical solution of this utility model is as follows: the first bracket and the second bracket each include two A-shaped brackets arranged side by side. The bottom end of the A-shaped bracket is fixedly connected to the base through a fixing device. The first rotating shaft and the first transmission shaft are arranged vertically and installed in the two A-shaped brackets of the first bracket.

[0009] This utility model discloses a novel 180-degree flipping mechanism for large sheet metal parts, which has the following beneficial effects: A support assembly is set on the base, and a transmission assembly and a flipping assembly are installed on the support assembly. The power of the motor is transmitted to the transmission assembly via a reducer. The small gears one and two of the transmission assembly drive the large gears one and two of the flipping assembly to rotate. The large sheet metal parts are clamped and fixed on the material support frame of the flipping assembly. As the large gears one and two rotate, the material support frame and the large sheet metal parts on it also rotate with the large gears one and two, realizing the automatic rotation of the large sheet metal parts within a 180-degree range. According to experimental data, after adopting this new flipping mechanism, the manual labor intensity is reduced by 90%, and the production efficiency is increased by 50%, achieving a significant reduction in manual labor intensity and an increase in production efficiency.
