[0032] Reference Figure 1-5 This utility model discloses a milling machine structure for surface processing of a speed reducer, comprising a worktable 1, with stabilizing rods 2 fixedly connected to the upper left and right sides of the worktable 1, rollers 3 rotatably connected above the stabilizing rods 2, a connecting plate 4 fixedly connected to the rear of the worktable 1, a connecting rod 5 fixedly connected above the connecting plate 4, a lifting device 6 provided at the other end of the connecting rod 5, the outer shell of the lifting device 6 being composed of a second frame 61, the second frame 61 being fixedly connected to the connecting rod 5, a first motor 62 fixedly connected above the second frame 61, a lifting screw 63 fixedly connected to the output end of the first motor 62, a lifting frame 64 threadedly connected above the lifting screw 63, a limit plate 65 fixedly connected below the lifting frame 64, and a second motor 66 fixedly connected below the lifting frame 64.

[0033] The above structure, by providing a stabilizing rod 2, which corresponds to the stabilizing groove 102, enables the stabilizing rod 2 to laterally limit the second slide table 101, allowing the second slide table 101 to move back and forth stably.

[0034] Driven by the first motor 62, the lifting screw 63 rotates. The lifting screw 63 is threadedly connected to the lifting frame 64, causing the lifting screw 63 to move the lifting frame 64 up and down.

The middle part of the second jaw 75 is fixedly connected to the locking tooth 76, and the locking tooth 76 corresponds to the locking block 81, so that the second jaw 75 locks the locking block 81 through the locking tooth 76 in the middle. The upper and lower edges of the inside of the second jaw 75 limit the locking block 81, so that the locking block 81 is stably located inside the second jaw 75.

A second slider 10 is slidably connected to the front and rear sides above the second slide table 101. 6. A clamping platform 11 is provided above the horizontal sliding frame 10.

[0039] The above structure, driven by the third motor 92, causes the longitudinal lead screw 93 to rotate. The first nut block 94 is threadedly connected to the middle of the longitudinal lead screw 93, and the first nut block 94 is fixedly connected to the second slide table 101, so that the longitudinal lead screw 93 drives the second slide table 101 to slide back and forth above the first slide table 91 through the first nut block 94.

[0040] Driven by the fourth motor 103, the transverse lead screw 104 rotates. A second nut block 105 is threadedly connected to the middle of the transverse lead screw 104, and a fourth frame 111 is fixedly connected above the second nut block 105. This allows the transverse lead screw 104 to drive the fourth frame 111 to slide back and forth above the second slide table 101 via the second nut block 105.

[0041] Driven by the fifth motor 112, the third bidirectional lead screw 113 rotates. Clamping plates 12 are threadedly connected to the left and right sides of the third bidirectional lead screw 113, causing the third bidirectional lead screw 113 to drive the clamping plates 12 on the left and right sides to move left and right.

[0042] By rotating the first knob 14, the first bidirectional lead screw 15 is rotated. The first jaws 16 are threadedly connected to the front and rear sides of the first bidirectional lead screw 15, so that the first bidirectional lead screw 15 drives the first jaws 16 on the front and rear sides to move back and forth.

[0043] Working principle: This type of reducer has a surface milling machine structure. In use, by rotating the first knob 14 in conjunction with the fifth motor 112, the reducer is clamped above the first jaws 16 on both sides. At this time, the first motor 62 is turned on to adjust the height of the grinding head 8. After the adjustment is completed, the switch of the second motor 66 is turned on to make the grinding head 8 rotate, thereby realizing the processing of the surface of the reducer. Under the action of the third motor 92 and the fourth motor 103, the surface of the reducer is controlled to move, so that the device can grind different positions on the surface of the reducer.
