[0042] Preferably, the line connecting the third rotation axis on the long ear plate and the fourth rotation axis on the short ear plate is parallel to the line connecting the first rotation axis on the first riser 214 and the second rotation axis on the second riser 215. When the first riser 214 rotates around the first rotation axis and the second riser 215 rotates around the second rotation axis, the connecting plate 216, the long ear plate, the short ear plate, and the storage box 217 always remain in a horizontal rotation state, so that the edge of the storage box 217 always faces upward, preventing the gears in the storage box 217 from falling outside the storage box 217 during rotation.

[0043] The limiting assembly 22 includes a limiting plate 221, a positioning slot 222 and a knob plunger 223. The limiting plate 221 is fixedly connected to the top left side of the base 211.

After the gears are placed in the two placement boxes 217, the upper placement box 217 is rotated in the opposite direction until the left side of the lower placement box 217 abuts the limit plate 221. At this time, the upper and lower placement boxes 217 are in a vertical distribution state; then the knob plunger 223 is rotated again to insert the inner end of the knob plunger 223 into the positioning groove 222 to fix the second vertical plate 215, thereby fixing the two placement boxes 217. The gears can be placed better by lowering the height of the upper placement box 217 so that the upper placement box 217 does not need to be placed with tools due to the upper placement box 217 being too high.

The first trapezoidal block 34 is slidably connected to the second trapezoidal block 38. Two spring buffers 39 are fixedly connected to the top inner wall of the fixed frame 35, and the bottoms of the two spring buffers 39 are fixedly connected to the top of the slide plate 37.

[0046] Preferably, the mounting frame 310 is fixedly connected to the top left side of the base plate 11. The top of the first trapezoidal block 34 is provided with left and right inclined surfaces in an inverted V-shaped structure, and the bottom of the second trapezoidal block 38 is provided with left and right inclined surfaces in a V-shaped structure.

[0047] When the first trapezoidal block 34 moves to the right and contacts and connects with the second trapezoidal block 38, the right inclined surface of the first trapezoidal block 34 and the left inclined surface of the second trapezoidal block 38 are fitted and slidably connected, and the horizontal surface of the first trapezoidal block 34 and the horizontal surface of the fixed frame 35 are fitted and slidably connected; when the first trapezoidal block 34 moves to the left and disengages from the second trapezoidal block 38, the left inclined surface of the first trapezoidal block 34 and the right inclined surface of the second trapezoidal block 38 are fitted and slidably connected, and the horizontal surface of the first trapezoidal block 34 and the horizontal surface of the fixed frame 35 are fitted and slidably connected.

When the right inclined surface of the first trapezoidal block 34 contacts the left inclined surface of the second trapezoidal block 38, due to the weight of the gear, the horizontal thrust generated by the friction between the first trapezoidal block 34 and the second trapezoidal block 38 cannot make the base 211 move on the roller 14, so that the second trapezoidal block 38 can move upward; when the first trapezoidal block 34 continues to move to the right, it drives the left inclined surface of the second trapezoidal block 38 to slide upward along the right inclined surface of the first trapezoidal block 34, and the second trapezoidal block 38 drives the slide plate 37 along the slide groove 3 6 slides upward and compresses the spring of the spring buffer 39 until the first trapezoidal block 34 moves to the right side of the second trapezoidal block 38, and the slide plate 37 moves downward and resets along the slide groove 36 under the spring elastic action of the spring buffer 39, and the slide plate 37 drives the second trapezoidal block 38 to move downward and reset; then the chain jacking elevator 31 continues to drive the fixed plate 32 to move right, the fixed plate 32 drives the slide plate 37 to move right, the slide plate 37 drives the fixed frame 35 to move right, the fixed frame 35 drives the base 211 to move right, thereby driving the placement box 217 to move right, until the placement box 217 is moved from the opening on the left side of the double-door heat treatment furnace 4 to the inside of the double-door heat treatment furnace 4;

[0049] Then the chain lifting elevator 31 drives the fixed plate 32 to move to the left, and the fixed plate 32 drives the fixed block 33 and the first trapezoidal block 34 to move to the left. When the left inclined surface of the first trapezoidal block 34 contacts the right inclined surface of the second trapezoidal block 38, due to the weight of the gear, the horizontal pulling force generated by the friction between the first trapezoidal block 34 and the second trapezoidal block 38 cannot make the base 211 move on the roller 14, so that the second trapezoidal block 38 can move upward; when the first trapezoidal block 34 continues to move to the left, driving the second trapezoidal block 38 The right inclined surface slides upward along the left inclined surface of the first trapezoidal block 34, and the second trapezoidal block 38 drives the slide plate 37 to slide upward along the slide groove 36 and compresses the spring of the spring buffer 39 until the first trapezoidal block 34 moves to the left side of the second trapezoidal block 38. The slide plate 37 moves downward along the slide groove 36 and resets under the spring elastic action of the spring buffer 39. The slide plate 37 drives the second trapezoidal block 38 to move downward and reset. At this time, the sealed door on the left side of the double-door heat treatment furnace 4 is closed, and the double-door heat treatment furnace 4 heats the gears.

[0050] When the gear heat treatment is completed, the sealed door on the left and the sealed door on the right side of the double-door heat treatment furnace 4 are opened at the same time, and the chain lifting elevator 31 drives the fixed plate 32 to move to the right and extend into the double-door heat treatment furnace 4, so that the fixed plate 32 pushes the fixed frame 35 to move to the right until the placement box 217 is moved from the opening behind the double-door heat treatment furnace 4 to the next process outside the double-door heat treatment furnace 4; then when the chain lifting elevator 31 drives the fixed plate 32 to move to the left and reset, until the first trapezoidal block 34 moves to the left side of the second trapezoidal block 38, finally the fixed plate 32 passes through the double-door heat treatment furnace 4 and returns to the initial position, increasing the chain service life of the chain lifting elevator 31; then a new gear placement assembly 21 is placed on the roller 14.
