When the gear is being processed, its position may be offset due to the gap, resulting in the angle of the tooth cutting being skewed or the depth of the tooth cutting not matching, thereby causing errors.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-6 , a gear processing error-proofing tool with adjustable inner diameter, comprising:

[0031] The operating table 1 has a circular opening.

[0032] The adjusting component 2 includes a sleeve 21, a first threaded rod 22, a bottom plate 23, a sliding rod 24 and a bending plate 25. The sleeve 21 is rotatably connected to a circular opening opened on the operating table 1 through an electric rotating component 4. A plurality of openings are equidistantly opened around the bottom of the sleeve 21. The first threaded rod 22 is rotatably connected to the center position of the electric rotating component 4 and passes through the operating table 1. The bottom plate 23 is rotatably connected to an end of the first threaded rod 22 away from the sleeve 21. One end of a plurality of sliding rods 24 is equidistantly fixed on the bottom plate 23. The bending plate 25 is slidably connected to the other end of the sliding rod 24 through a sliding component 5. By rotating the first rotating threaded rod, the bottom plate 23 moves upward, the bottom plate 23 drives the sliding rod 24 to move upward, the sliding rod 24 slides along the top of the bending plate 25, pushes the bending plate 25 outward, and rotates the first rotating threaded rod in the opposite direction, so that the bending plate 25 is retracted toward the sleeve 21.

[0033] The fixing assembly 3 includes a connecting rod 31, an annular plate 32 and a telescopic rod 33. One end of the connecting rod 31 is fixedly connected to one end of the bending plate 25 close to the sleeve 21. The annular plate 32 is fixedly connected to the other end of the connecting rod 31 and is slidably arranged in the bottom opening of the sleeve 21. The size of the annular plate 32 is consistent with the size of the opening opened on the sleeve 21. One end of the telescopic rod 33 is fixedly connected to the inner wall of the sleeve 21, and the other end is fixedly connected to one end of the bending plate 25 close to the sleeve 21. The telescopic rod 33 is arranged parallel to the connecting rod 31 up and down. When the bending plate 25 is pushed outward, the annular plate 32 can be pushed out of the inner wall of the sleeve 21 through the connecting rod 31, and the telescopic rod 33 is extended. When the bending plate 25 is retracted toward the sleeve 21, the telescopic rod 33 returns to its original state.

[0034] In the embodiment of the above technical solution, the gear to be processed is sleeved on the sleeve 21, and the first threaded rod 22 is rotated in one direction so that the first threaded rod 22 drives the bottom plate 23 to move upward, and the bottom plate 23 drives the sliding rod 24 to slide upward in the slide groove 51 of the bending plate 25. The bending plate 25 can push the annular plate 32 out of the inner wall of the sleeve 21 through the connecting rod 31, and the telescopic rod 33 is extended, and the annular plate 32 is against the inner ring of the gear, so that the gear can be fixed and will not be displaced. The first threaded rod 22 is rotated in the opposite direction to retract the annular plate 32. When the present invention is operated, gears of various inner diameters can be fixed by rotating the first threaded rod 22. The operation is simple and very fast, and there is no high technical requirement. In addition, no position offset will occur when processing the gear, resulting in various errors, which greatly increases the processing speed and quality of the gear and reduces the deviation rate of the processed gear, thereby achieving the purpose of error prevention.

[0035] The ends of the bending plate 25 and the sliding rod 24 that are close to each other are both arranged as inclined surfaces, and the two inclined surfaces are parallel to each other. The parallelism of the inclined surfaces can cause sliding under the action of external force.

The first rotating ring 41 and the second rotating ring 42 are concentric rings. The two ends of the multiple rotating shafts 43 are respectively fixedly connected to the inner walls of the first rotating ring 41 and the second rotating ring 42. When processing gears, the electric rotating component 4 causes the adjusting component 2 and the fixing component 3 to rotate simultaneously, which is convenient for gear processing.

[0037] The sliding assembly 5 includes a slide groove 51, a slider 52 and a slide rod 53. The slide groove 51 is opened at one end of the bending plate 25 away from the sleeve 21.

The first threaded rod 22 can be controlled to move up and down by rotating the adjusting disk 6 .

[0039] A vertical adjustment component 7 is also fixed on the operating table 1, and the vertical adjustment component 7 is used to limit the up and down movement of the gear being processed to avoid deviation during processing.

[0040] The vertical adjustment assembly 7 includes a column 71, a fixing plate 72, a second threaded rod 73, an adjustment block 74 and a pressing piece 75. The column 71 is vertically fixed on the operating table 1. The two fixing plates 72 are fixedly sleeved at both ends of the column 71. The fixing plate 72 is provided with a threaded hole at one end away from the column 71. The second threaded rod 73 is threadedly sleeved in the threaded holes of the two fixing plates 72. The adjustment block 74 has two round openings, and one of the round openings is provided with a thread. The round opening with a thread is threadedly sleeved on the second threaded rod 73, and the other round opening is slidably provided on the column 71. The adjustment block 74 is provided with two round openings, and the second threaded rod 73 is threadedly sleeved on the second threaded rod 73. The other round opening is slidably provided on the column 71. A square groove is also provided at one end away from the second threaded rod 73, and the square groove penetrates two mutually perpendicular side surfaces of the adjusting block 74. The pressing piece 75 is arranged at one end of the adjusting block 74 away from the second threaded rod 73 through the buckle assembly 8. The end of the pressing piece 75 away from the second threaded rod 73 is in a semicircular hook shape and extends above the sleeve 21. After the gear is sleeved on the sleeve 21, the second threaded rod 73 is rotated to drive the adjusting block 74 to slide up and down, and the adjusting block 74 drives the pressing piece 75 to move up and down. The pressing piece 75 is adjusted to the top of the gear and rotated to press the gear, so as to limit the gear from deviating up and down.

[0041] The buckle assembly 8 includes a first rotating shaft 81, a second rotating shaft 82 and a clamping block 83. The first rotating shaft 81 is fixedly connected in the square groove of the adjusting block 74. The second rotating shaft 82 rotates through one end of the pressure piece 75 close to the column 71, and both ends of the second rotating shaft 82 are fixedly connected in the square groove of the adjusting block 74. The clamping block 83 is rotatably connected to the first rotating shaft 81. When the clamping block 83 is clamped on the second rotating shaft 82, the pressure piece 75 is fixed and cannot rotate.

[0042] The clamping block 83 is F-shaped and is rotatably clamped on the second rotating shaft 82 .

[0043] An adjusting handle 9 is fixed to one end of the second threaded rod 73 away from the operating table 1 .
