Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to an automatic clamping device for planetary carrier machining. Background Technology

[0002] Planetary carriers are important mechanical gear transmission devices, consisting of sun gears, planet gears, internal gear shafts, etc. They can achieve high transmission ratios, large torques, and high efficiency, and are widely used in various mechanical equipment, such as automobile gearboxes and marine transmission devices. At present, automatic clamping devices are required to fix planetary carriers during processing to facilitate their machining operations.

[0003] Currently, automatic clamping devices for planetary carrier machining typically involve placing the planetary carrier to be processed on a worktable and clamping it by activating the drive mechanism. However, since planetary carriers come in various specifications, in actual operation, some automatic clamping devices require replacement with the appropriate device when clamping different sizes of circular planetary carriers, thus presenting significant limitations. Furthermore, because the edges of circular planetary carriers are curved, their surface area is relatively small, making them prone to slippage during clamping operations, which can hinder machining.

[0004] In summary, the following shortcomings have been gradually discovered in the current automatic clamping devices for planetary carrier machining:

[0005] 1) Some automatic clamping devices can only clamp circular planetary carriers of a specified size, which has significant limitations;

[0006] 2) Because the edges of the circular planetary carrier are curved, its surface area is relatively small, making it easy to slip when clamping it. Utility Model Content

[0032] like Figures 1 to 5 As shown in the figure, this embodiment provides an automatic clamping device for planetary carrier processing. This automatic clamping device for planetary carrier processing includes a frame 1, a placement platform 101 fixedly connected to the top of the frame 1, a hydraulic cylinder 2 fixedly connected to the bottom of the frame 1, a lifting plate 3 provided inside the frame 1, the output end of the hydraulic cylinder 2 extending into the interior of the frame 1 and fixedly connected to the lifting plate 3, connecting rods 4 movably connected to both sides of the lifting plate 3, a positioning plate 5 fixedly connected to the end of the connecting rod 4 away from the lifting plate 3, a drive plate 6 fixedly connected to the outer surface of the positioning plate 5, the drive plate 6, the positioning plate 5 and the connecting rod 4 forming an L-shape, the drive plate 6, the positioning plate 5 and the connecting rod 4 are arranged in pairs and correspondingly, an L-shaped block 7 is provided between the two sets of drive plates 6, one side of the L-shaped block 7 is arc-shaped 701, so as to facilitate the clamping operation on the outer surface of the circular planetary carrier.

[0033] A vertical plate 8 is fixedly connected to the top of the frame 1. A limiting groove 102 is opened at the top of the frame 1. There are two sets of limiting grooves 102, which are located on both sides of the vertical plate 8 respectively. The connecting rod 4 passes through the limiting groove 102 and is movably connected to it. One end of the connecting rod 4 extends through the limiting groove 102 to the top of the frame 1 and is fixedly connected to the positioning plate 5 to facilitate the movement of the connecting rod 4.

[0034] The placement platform 101 is located on top of the upright plate 8 and also on top of the T-shaped strip 802.

[0035] Both sides of the lifting plate 3 are fixedly connected with first guide rods 301, and the first guide rods 301 are arranged at equal intervals;

[0036] The connecting rod 4 has a first guide groove 401 inside. The first guide rod 301 is located inside the first guide groove 401 and is movably connected to it. The lifting plate 3 and the connecting rod 4 are connected to the first guide groove 401 through the first guide rod 301. The first guide rod 301 can move the driving connecting rod 4 by moving inside the first guide groove 401.

[0037] Positioning shafts 801 are fixedly connected to both sides of the upright plate 8. Two sets of positioning plates 5 are located on both sides of the upright plate 8 and are rotatably connected to the upright plate 8 through the positioning shafts 801. This allows the connecting rod 4, the drive plate 6, and the positioning plate 5 to deflect around the positioning shafts 801, thereby driving the two sets of L-shaped blocks 7 to move closer or further apart, so as to clamp circular planetary carriers of different specifications.

[0038] The top of the upright plate 8 has a T-shaped strip 802, and a slider 9 is slidably connected above the T-shaped strip 802. There are two sets of sliders 9, which correspond to each other. The two sets of sliders 9 are located on both sides of the placement platform 101. The inside of the slider 9 is provided with a T-shaped groove that is slidably connected to the T-shaped strip 802. Both sides of the slider 9 have a second guide rod 901.

[0039] The drive plate 6 has a second guide groove 601 inside, and the second guide rod 901 is located inside the second guide groove 601 and is movably connected to it, which can facilitate driving the two sets of sliders 9 to move closer or further apart, and facilitate clamping or not clamping the circular planetary carriers of different specifications.

[0040] The L-shaped block 7 is located above the slider 9 and the two are fixedly connected. An electric push rod 10 is fixedly connected to the top of the L-shaped block 7. A connecting rod 11 is fixedly connected to the output end of the electric push rod 10. The connecting rods 11 are arranged at equal intervals. A pressure plate 12 is fixedly connected to the other end of the connecting rod 11. By fixing the top of the circular planetary carrier, its stability can be increased, thereby reducing the risk of slippage.

[0041] Rubber strips 13 are installed at the bottom of the pressure plate 12. The rubber strips 13 are arranged at equal intervals. The pressure plate 12 is semi-circular, and the multiple sets of rubber strips 13 are all arc-shaped. The pressure plate 12 and the rubber strips 13 are both located above the placement platform 101, which can facilitate the fixation of the top of the circular planetary carrier. At the same time, the setting of the rubber strips 13 can increase the stability of the circular planetary carrier.

[0042] In use, the circular planetary carrier to be processed is placed on the placement table 101. Then, the hydraulic cylinder 2 is activated to drive the lifting plate 3 to descend. The lifting plate 3 drives the first guide rod 301 to descend along the inner wall of the first guide groove 401 to apply pressure to the connecting rod 4. At the same time, it descends along the inside of the first guide groove 401 and drives the connecting rod 4 to drive the positioning plate 5 to deflect around the positioning shaft 801 with the pressure of the first guide rod 301. This drives the drive plate 6 to move towards the placement table 101, so that the inner wall of the second guide groove 601 applies a pushing force to the second guide rod 901. The second guide rod 901 moves along the inside of the second guide groove 601, so that the two sets of sliders 9 drive the L-shaped block 7 to move towards the placement table 101 until the arc surface 701 is in close contact with the outer surface of the circular planetary carrier, thus completing the clamping operation. This method can be adapted to circular planetary carriers of different specifications, thereby increasing its practicality.

[0043] Then, by activating the electric push rod 10, it drives the pressure plate 12 to descend via the connecting rod 11 until the rubber strip 13 at the bottom of the pressure plate 12 is in close contact with the top of the circular planetary carrier. This completes the fixing of the top of the circular planetary carrier. With the help of the L-shaped block 7 clamping its outer surface, the slippage phenomenon can be reduced, thereby increasing the stability of clamping the circular planetary carrier and improving the efficiency of processing the circular planetary carrier.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
