Description

Technical Field

[0001] This utility model relates to the field of planetary carrier processing technology, and in particular to an automatic welding fixture for gearbox planetary carriers. Background Technology

[0002] The primary function of the planet carrier is to mount and support multiple planetary gears (satellite gears). These planetary gears are typically evenly distributed on the planet carrier and rotate around a central axis. The planet carrier itself can serve as the input shaft, output shaft, or stationary component of the planetary gear mechanism, depending on the transmission design.

[0003] Traditional planetary carrier welding fixtures typically require manual rotation of the workpiece or rely on complex reversing mechanisms, which are cumbersome to operate and difficult to guarantee positioning accuracy. At the same time, existing fixed fixtures have poor adaptability to welding requirements of different planetary carrier specifications, and frequent fixture changes lead to low efficiency and difficulty in ensuring the consistency of welding paths.

[0025] Reference Figure 1-4This embodiment of the present invention provides an automatic welding fixture for a planetary carrier of a gearbox, which can achieve the following effects: it includes a processing table 101, a lifting plate 102 fixedly installed on one side of the processing table 101, and an installation groove 201 on the processing table 101. The fixture is characterized in that: a rotating component 202 for rotating the planetary carrier is installed in the installation groove 201; a fixing device 203 is fixedly installed on the rotating component 202; a fixing component 204 for fixing the planetary carrier is installed in the fixing device 203; two sets of electric slide rails are symmetrically arranged on the lifting plate 102; a welding frame 103 is slidably arranged on the two sets of electric slide rails; an automatic welding gun is installed on the welding frame 103; and the length of the welding frame 103 can be adjusted according to actual conditions to adapt to planetary carriers of different specifications.

[0026] Reference Figure 2 It includes a rotating component 202, a first motor 2021 fixedly installed in a mounting groove 201, a worm gear 2022 fixedly installed at the output end of the first motor 2021, a worm wheel 2023 rotatably installed at the bottom of the mounting groove 201, a rotating disk 2024 fixedly installed at the upper end of the worm wheel 2023, and a connecting disk 2025 fixedly installed on the rotating disk 2024.

[0027] Reference Figure 3-4 It includes a fixing component 204, including a second motor 2041 fixedly mounted on a connecting plate 2025, a rotating disk 2042 fixedly mounted on the upper end of the second motor 2041, a connecting rod 2043 rotatably mounted on the rotating disk 2042, a slider 2044 rotatably mounted on the connecting rod 2043, a limiter 2045 fixedly mounted inside the fixing device 203, a clamping plate 2046 fixedly mounted on the slider 2044, an electric cylinder 2047 mounted on the clamping plate 2046, the slider 2044 slidably mounted on the limiter 2045 and moving horizontally along the direction of the limiter 2045, a sliding groove is provided on the fixing device 203, and the bottom of the clamping plate 2046 is tightly fitted and slidably connected to the inner wall of the sliding groove.

[0028] Operating steps: Place the planetary carrier to be welded between the clamping plates 2046 inside the fixture 203. Start the second motor 2041 to drive the rotating disk 2042 to rotate. The rotating disk 2042 drives the slider 2044 to slide horizontally on the limiter 2045 via the connecting rod 2043. The slider 2044 drives the clamping plates 2046 to move towards each other, initially clamping the planetary carrier. Activate the electric cylinder 2047 on the clamping plate 2046 to provide additional clamping force, firmly fixing the planetary carrier in the fixture 203. Adjust the position and length of the welding frame 103 on the electric slide rails on both sides of the lifting plate 102 according to the specifications of the planetary carrier, so that the automatic welding gun installed on the welding frame 103 is aligned with the axis of rotation. The automatic welding gun is then started to weld the part of the planetary carrier to be welded. At the same time, the first motor 2021 is started to drive the worm gear 2022 to rotate. The worm gear 2022 drives the worm wheel 2023 meshing with it to rotate. The worm wheel 2023 drives the rotating disk 2024 and the connecting disk 2025 fixed to it to rotate together. The retainer 203 fixed on the connecting disk 2025 and the planetary carrier clamped inside it rotate at a uniform speed. Under the clamping of the fixed part 204, the planetary carrier continues to rotate with the rotating part 202. The automatic welding gun performs continuous and uniform welding on the rotating planetary carrier. When the planetary carrier has rotated one revolution or reached the predetermined welding requirements, the welding stops, the first motor 2021 stops rotating, and the planetary carrier stops rotating.
