Technical Field

[0001] The utility model belongs to the technical field of planet carrier processing, and particularly relates to a drilling tool for a planet carrier. Background Technique

[0002] The planet carrier is one of the main components of the planetary gear transmission device. The planet carrier is an important part of the planetary gear transmission system, which is used to support the planetary gear shaft or bearing, and plays roles such as changing the transmission direction, decelerating, and accelerating in the transmission device, and realizes the transmission effect by changing the relative movement between the gears.

[0003] Multiple slots need to be machined inside the planet carrier to accommodate the planetary gears. The fit between the planetary gear and the planet carrier needs to be ensured by high-precision machining. Through drilling, the position accuracy, hole diameter size, and surface finish of the planetary gear hole can be ensured, thereby improving the fit accuracy between the planetary gear and the planet carrier, reducing the assembly error and transmission noise. In order to improve the drilling effect of the planet carrier, it is necessary to clamp and fix the planet carrier with a drilling tooling. The existing drilling tooling has a slow fixing method for the planet carrier and cannot clamp and fix planet carriers of various different sizes. The problems existing in the above technology are: the fixing method of the drilling work for the planet carrier is not fast enough, and it cannot quickly clamp and fix planet carriers of various different sizes.

When it is necessary to adjust the positions of the two auxiliary rods 501 to clamp and fix the planet carrier 104, rotate the screw rod 504. The rotation of the screw rod 504 will cause the movable block 503 to move left or right. The movement of the movable block 503 will cause the two rotating rods 502 to move. During the movement of the two rotating rods 502, the two auxiliary rods 501 will rotate through the moving plates 3. The usage methods of the two auxiliary fixing components 5 are the same. By operating the plurality of telescopic columns 402, the output ends of the plurality of telescopic columns 402 drive the plurality of clamping blocks 401 and the two moving plates 3 to move in the direction of the opposite ends, so that the two clamping components 6 and the two auxiliary fixing components 5 clamp and fix the planet carrier 104.
