[0042] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0043] The device is powered on by the stable support of the base 1; the sun gear can be installed through the drive assembly 4; the three planetary gears can be installed through the limiting wheel structure 5; the gear ring in the planetary gear set can be limited and placed through the fixed ring assembly 3;

[0044] That is, the sun gear is mounted on the drive shaft 43, which is located above the adjustment platform 51; the planetary gear is mounted on the planetary shaft 60, and the shaft seat 55 can be adjusted according to the diameter of the planetary gear, and the adjustment arm 53 is fixed by the mounting bolt 54 to mesh the planetary gear with the sun gear for transmission, and the shaft seat 55 is fixed and limited by the second adjustment bolt 57;

[0045] By controlling the second electric slide rail 32 to drive the two clamping seats 33 to move relative to each other, the gear ring can be clamped between the clamping rollers 34 to limit the position, and at the same time, the lower wall of the gear ring is attached to the upper wall of the clamping seat 33; then, the first hydraulic cylinder 31 is extended to lower the gear ring, so that it can be mounted on the outer side of the planetary gear for engagement, thereby realizing the assembly limit of the planetary gear set;

[0046] The first motor 42 in the driving housing 41 drives the driving shaft 43 to rotate with the help of the first bearing 47, thereby driving the sun gear to rotate.

[0047] When the sun gear rotates, if the clamping roller 34 fixes the gear ring and makes the gear ring unable to rotate, it will drive the planetary gear to move in engagement with the inner circumference of the gear ring, and drive the adjustment platform 51 to rotate through the second bearing 52, and the planetary gear will also rotate through the third bearing 56 with the help of the planetary shaft 60 along with the engagement transmission; at this time, the eddy current seat 25 can be powered to drive the eddy current seat 25 to be located on the upper and lower sides of the planetary gear teeth for heating and quenching, and the temperature will be evenly increased with the rotation of the planetary gear;

[0048] When the sun gear rotates, the clamping roller 34 does not clamp the gear ring. At this time, the gear ring can be rotated by force with the help of the clamping seat 33 and the clamping roller 34, and the second hydraulic cylinder 45 on the support arm 44 is extended to drive the top claw 46 to fit and press against the side wall of the adjustment platform 51, so that the adjustment platform 51 is fixed and limited; the adjustment platform 51 cannot rotate, and the sun gear rotates and drives the planetary gear.

The drive housing (41) is fixedly arranged in the middle of the upper wall of the base (1) and is located below the first electric slide rail (23). The drive housing (41) is located between the other ends of the quenching arms (24), and a first bearing (47) is embedded in the middle of the upper wall of the drive housing (41). The first motor (42) is fixedly arranged in the drive housing (41). One end of the drive shaft (43) is fixedly passed through the middle of the first bearing (47) and is fixedly connected to the drive end of the first motor (42). One end of the support arm (44) is detachably arranged in the middle of the front side wall of the drive housing (41). The second hydraulic cylinder (45) is fixedly arranged on the other end of the support arm (44). One end of the top claw (46) is fixedly arranged on the telescopic end of the second hydraulic cylinder (45), and the other end of the top claw (46) is opposite to the drive shaft (43).

4. The tooth surface processing device for planetary gear machining according to claim 3, characterized in that: The regulating arm (53) is located below the clamping roller (34) and above the quenching arm (24) at the bottom end of the first electric slide rail (23).

5. The tooth surface processing device for planetary gear machining according to claim 4, characterized in that: The quenching arm (24) on the first movable seat of the first electric slide rail (23) is located above the adjustment arm (53).

6. The method for using the tooth surface processing device for planetary gear machining according to claim 5, characterized in that: The following steps are involved: Step 1: Mount the sun gear on the drive shaft (43), mount the three planetary gears on the planetary shafts (60), drive the sun gear to rotate through the drive assembly (4), promote the meshing transmission of the three planetary gears with the sun gear, and tighten the adjustment table (51) in the wheel limiting structure (5) to limit the position, so that the planetary gears can be driven to rotate and the tooth surfaces can be meshed to remove burrs; Step 2: clamp the gear ring by the fixing ring assembly (3) to limit the position. When the fixing ring assembly (3) clamps the gear ring and the gear ring cannot rotate, the adjustment platform (51) is unlocked under the drive of the sun gear, so that the planetary gear can rotate in the inner circumference of the gear ring with the help of the adjustment platform (51), thereby realizing the overall assembly process; or the adjustment platform (51) is fixed to cause the gear ring to rotate with the help of the clamping roller (34); In the operations of step 1 and step 2, the internal teeth of the gear ring or the external teeth of the planetary gear or the external teeth of the sun gear are heated by the quenching structure (2) by means of a magnetic field, and the tooth surface is quenched to improve the strength.
