Further, the positioning shaft is in clearance fit with the wheel axle fixing hole on the planet carrier. Further, the height of the positioning shaft which is exposed outside the bottom end surface of the placing groove under the natural state of the elastic part exceeds the thickness of the fixing disc of the planet carrier wheel axle. Further, a thread is arranged at the lower end of the positioning hole, the elastic part is matched with the thread through a screw for being positioned in the positioning hole and connected with the bottom end of the positioning shaft, and the elastic part is a spring or an elastic metal sheet. Further, the positioning disc is matched with the placing groove, the bottom end surface of the positioning disc is horizontally arranged, through holes which are vertical to the bottom end surface of the positioning disc are arranged on the positioning disc, each through hole corresponds to the wheel axle fixing hole on the planet carrier and the diameter of each through hole is 0.2-0.3mm larger than that of the wheel axle fixing hole on the planet carrier. Further, the positioning shaft is in clearance fit with one through hole on the positioning disc. After the technical scheme is adopted, the invention has the following advantages: the planet carrier is positioned through the placing groove and the positioning shaft so as to ensure the accurate positioning, the positioning disc is further used for assisting the guarantee of the verticality of the wheel axle, the operation is simple and convenient, the difficulty in operation of a worker is reduced, and the production efficiency and the product quality are further improved. Brief Description of the Drawings In combination of the following figures, the invention is further described. Figure 1 is a schematic diagram of sectional structure of one embodiment of the invention; Figure 2 is a top view of fixed seat; Figure 3 is a top view of positioning disc; Figure 4 is a schematic diagram of sectional structure of embodiment as shown in Figure 1 during using process; Figure 5 is a schematic diagram of structure of planet carrier finished product. Detailed Description of the Invention According to a schematic diagram of the structure of one embodiment of the invention as shown in Figures 1-5, an auxiliary device for pressing a planet carrier wheel axle comprises a fixed seat 1, an unthreaded hole 11 for penetrating and arranging a planet carrier rotating shaft 81 is arranged in the fixed seat 1, a placing groove 12 for placing a fixing disc 82 of the planet carrier wheel axle is arranged above the unthreaded hole 11, the bottom end surface of the placing groove 12 is 2 horizontally arranged, a positioning hole 13 is vertically arranged on the bottom end surface of the placing groove 12, a positioning shaft 3 which can move up and down is arranged in the positioning hole 13, the positioning shaft 3 corresponds to a wheel axle fixing hole 83 on a planet carrier, an elastic part 4 for pushing the positioning shaft 3 upwards is further arranged below the positioning shaft 3 in the positioning hole 13, the positioning shaft 3 is in clearance fit with the wheel axle fixing hole 83 on the planet carrier and the height of the positioning shaft 3 which is exposed outside the bottom end surface of the placing groove 12 under the natural state of the elastic part 4 exceeds the thickness of the fixing disc 82 of the planet carrier wheel axle; in addition, a positioning disc 2 which is matched with the positioning shaft 3 for positioning the wheel axle 84 is further arranged in the placing groove 12, the positioning disc 2 is matched with the placing groove 12, the bottom end surface of the positioning disc 2 is horizontally arranged, through holes 21 which are vertical to the bottom end surface of the positioning disc are arranged on the positioning disc 2, each through hole corresponds to the wheel axle fixing hole 83 of the planet carrier, the diameter of each through hole 21 is 0.2-0.3mm larger than that of the wheel axle fixing hole 83 on the planet carrier, and the positioning shaft 3 is in clearance fit with one through hole 21 on the positioning disc 2. In the embodiment, a step I 31 is arranged at the lower end of the positioning shaft 3, a step 11132 which is matched with the step I 31 is arranged in the positioning hole 13, the positioning shaft 3 uses the step I 31 to push against the step 11132 for limiting the position, a thread 131 is arranged at the lower end of the positioning hole 13, the elastic part 4 is matched with the thread 131 through a screw 5 for being positioned in the positioning hole 13 and connected with the bottom end of the positioning shaft 3, and the elastic part 4 is a spring or an elastic metal sheet; when the planet carrier which needs to press the wheel axle is placed in the fixed seat, the positioning shaft is arranged into the wheel axle fixing hole on the planet carrier by penetration, the positioning is convenient, then the positioning disc is placed on the planet carrier so as to enable the positioning shaft which is exposed outside the fixing disc of the planet carrier wheel axle to be arranged in one through hole on the positioning disc, then the positioning disc is fixed through the placing groove and the positioning shaft, and the wheel axle further penetrates the through hole of the positioning disc and is pressed into the wheel axle fixing hole of the planet carrier.
