Description

Technical Field

[0001] The utility model relates to the technical field of planetary gear processing, in particular to a hoisting fixture for planetary gear processing. Background Art

[0002] Planetary gear machining is a complex and delicate process involving multiple steps and stringent process requirements. A lifting fixture is an essential tool in the process, primarily used to hoist and secure the planetary gear during machining. The hoisting system uses a lifting device to lift the fixture to the designated position. A clamping mechanism secures the planetary gear to the fixture through clamping force. The fixture uses guiding and positioning devices to ensure the stability and accuracy of the planetary gear.

[0003] However, the existing lifting fixtures for planetary gear processing have poor stability, mainly because the existing lifting fixtures usually use an internal support method to fix and lift the planetary gear from the inside. However, once the planetary gear is hit and affected by its own gravity, it is very easy to loosen, causing the planetary gear to detach. Therefore, a lifting fixture for planetary gear processing is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of poor stability of the existing hoisting fixture for processing planetary gears. The utility model provides a hoisting fixture for processing planetary gears.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A lifting fixture for planetary gear processing includes a cross bar, two hooks fixedly installed on the top of the cross bar, two inner support rods provided at the bottom of the cross bar, a driving mechanism for driving the two inner support rods to move away from or approach each other is provided inside the cross bar, a circular plate 1 is provided directly below the cross bar, three evenly distributed L-shaped blocks are provided around the circular plate 1, a lifting block is provided directly below each L-shaped block, and two groups of telescopic rod assemblies for driving two adjacent lifting blocks to lift and lower are provided on the bottom surface of the horizontal end of each L-shaped block, a transmission mechanism for driving the three L-shaped blocks to spread or gather is provided on the circular plate 1, and a lifting mechanism for driving the circular plate 1 to lift and lower is provided at the bottom of the cross bar.

[0007] Furthermore, the driving mechanism includes a strip groove, a strip groove is opened at the bottom of the cross bar, a rotatable bidirectional screw is movably installed inside the strip groove, a servo motor for driving the bidirectional screw to rotate is fixedly installed on the side wall of the cross bar, and movable blocks are respectively threadedly connected at both ends of the bidirectional screw, and a connecting rod is fixedly installed at the bottom of each movable block, and the two connecting rods are respectively fixedly connected to the two inner support rods.

[0008] Furthermore, the telescopic rod assembly includes a round tube, two round tubes are fixedly installed on the bottom surface of the horizontal end of each L-shaped block, round rods are movably installed inside the round tubes, and a spring is fixedly installed on the top of each round rod.

[0009] Furthermore, the transmission mechanism includes an execution motor, an execution motor is fixedly installed on the top of circular plate one, and the output end of the execution motor passes through circular plate one and is fixedly connected to circular plate two. Three evenly distributed arc holes are provided at the bottom of circular plate two, and three slide grooves one are provided at the bottom of circular plate one. A slide rod one is movably installed inside each slide groove one, and a cylindrical block is fixedly installed at the bottom of each slide rod one. The three cylindrical blocks respectively pass through the interiors of the three arc holes, and a slide groove two is provided at the bottom of each slide rod one. A slide rod two is movably installed inside each slide groove two, and one end of each slide rod two away from the adjacent cylindrical block is fixedly connected to the adjacent L-shaped block.

[0010] Furthermore, the transmission mechanism also includes a strip hole 1, the inner top surface of each slide groove 1 is provided with a strip hole 1, the top of each slide rod 2 is fixedly installed with a screw rod passing through the strip hole 2, and each screw rod is threadedly connected with a nut.

[0011] Furthermore, the lifting mechanism includes a U-shaped frame, a detachable hydraulic rod is provided at the bottom of the cross bar, the output end of the hydraulic rod is fixedly connected to the U-shaped frame, the U-shaped frame is fixedly installed on the top of the circular plate, a block is fixedly installed inside the strip groove, a bidirectional screw passes through the block, a threaded groove is opened at the bottom of the block, the internal thread of the thread groove is connected to a threaded rod, and the threaded rod is fixedly connected to the hydraulic rod.

[0012] The beneficial effects of the utility model are as follows:

[0013] When the two inner support rods are placed inside the planetary gear, the two inner support rods are first placed inside the planetary gear, and then the driving mechanism is started to move the two inner support rods away from each other. At this time, the two inner support rods support each other from the inside of the planetary gear to achieve the purpose of clamping the planetary gear. The hook can facilitate the lifting mechanism to lift the cross bar. In order to prevent the planetary gear from loosening during the lifting process, when the two inner support rods are placed inside the planetary gear, the lifting mechanism is controlled to lower the circular plate. When the circular plate is lowered, the three L-shaped blocks are driven to lower synchronously. When the circular plate is lowered, the three L-shaped blocks are driven to lower synchronously. When the lifting block touches the bottom surface, it squeezes the corresponding two sets of telescopic rod assemblies to contract. At this time, if the planetary gear is lifted, the transmission mechanism is immediately controlled to spread the three L-shaped blocks. After the lifting block is separated from the ground, each set of telescopic rod assemblies drives the corresponding lifting block to move downward, and cooperates with the lifting mechanism to move the circular plate upward so that the top of each lifting block is in contact with the bottom surface of the planetary gear, thereby preventing the planetary gear from disengaging.

The hook 2 can facilitate the lifting mechanism to lift the cross bar 1. In order to prevent the planetary gear from loosening during the lifting process, when placing the two inner support rods 3 inside the planetary gear, the lifting mechanism 10 is controlled to lower the circular plate 5 at the same time. When the circular plate 5 falls, it will drive the three L-shaped blocks 6 to move down synchronously. When the lifting block 7 touches the bottom surface, it will squeeze the corresponding two sets of telescopic rod assemblies 8 to shrink. At this time, if the planetary gear is lifted, the transmission mechanism 9 will be immediately controlled to spread the three L-shaped blocks 6. After the lifting block 7 is separated from the ground, each set of telescopic rod assemblies 8 will drive the corresponding lifting block 7 to move downward, and cooperate with the lifting mechanism 10 to move the circular plate 1 upward, so that the top of each lifting block 7 is in contact with the bottom surface of the planetary gear, thereby preventing the planetary gear from disengaging.
