In the actual working process, due to the different specifications of the planetary carrier, there are planetary carriers with various sizes of outer diameters and inner diameters. This patent is not easy to make adaptive adjustments to this situation, and its use is very limited. Therefore, a hydraulic tooling device for the planetary carrier is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a hydraulic tooling device for a planetary carrier, which can achieve the effect of adaptive self-adjustment of planetary carriers of various specifications and can always achieve the effect of centering clamping and applying a clamping force.

[0006] The technical solution for achieving the purpose of the utility model is: a hydraulic tooling device for a planetary carrier, comprising a workbench, a plurality of L-shaped clamps are slidably connected to the upper surface of the workbench, a fixed table is arranged below the workbench, a hydraulic cylinder is arranged on the fixed table, a centering fixing component is arranged at the output end of the hydraulic cylinder, the centering fixing component is connected to the L-shaped clamp, and each of the L-shaped clamps is provided with an auxiliary fixing component.

[0007] In some embodiments, the centering and fixing assembly includes a moving block fixedly connected to the top of the hydraulic cylinder, and the moving block is rotatably connected to a plurality of connecting rods around the moving block, and the plurality of connecting rods are evenly distributed around the moving block.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model provides a centering fixing component and a hydraulic cylinder. When the planet carrier needs to be fixed, the hydraulic cylinder is started, the hydraulic cylinder contracts and drives the moving block to descend in height, the connecting rod is pulled downward and deflected, and the connecting rod drives the L-shaped clamp block to move toward the planet carrier synchronously at the same time, so that the planet carrier can be clamped and maintained at the most central position of the workbench. At the same time, within the stroke of the hydraulic cylinder, the centering fixing component of the device can be driven by the hydraulic cylinder to clamp and fix the planet carriers of different outer diameters, thereby greatly improving the practicality of the device.

[0013] Second, the utility model provides an auxiliary fixing assembly on the L-shaped clamping block. After the L-shaped clamping blocks on all sides initially complete the fixing and clamping, the threaded rod is rotated, and the threaded rod moves downward to drive the fixing plate to move downward, and finally a vertical pressure is applied to the planetary frame in the vertical direction, thereby achieving the best stable fixing effect, preventing the planetary frame from slipping or shaking during the processing, and further improving the fixing effect of the device for the circular planetary frame;

[0014] The invention solves the problem that the existing planet carrier fixing tool cannot be adaptively adjusted to planet carriers of different sizes and has strong limitations in use. BRIEF DESCRIPTION OF THE DRAWINGS

Relative to the workbench 1 or the planetary carrier, the L-shaped clamps 2 are evenly distributed around it to achieve the effect of centering clamping and fixing, and the position where the L-shaped clamp 2 contacts the planetary carrier is also an arc shape adapted to the outer arc of the planetary carrier to achieve a better fitting effect.

[0024] like Figure 2-3 As shown, in one embodiment, the centering fixing assembly 5 includes a moving block 501 fixedly connected to the top of the hydraulic cylinder 4, and corresponding connecting grooves are provided around the moving block 501. A plurality of connecting rods 502 are rotatably connected around the moving block 501. The connecting rods 502 correspond to the connecting grooves one by one and are slidably connected to the inner wall of the connecting grooves. The plurality of connecting rods 502 are evenly distributed around the moving block 501.
