The support base 100 is formed with a cutter passing channel 120 along a first direction 30 parallel to the central axis of the boss 110. One end of the cutter passing channel 120 extends to an end surface of the supporting seat 100 facing away from one end of the convex column 110, and the other end extends to the end surface of the convex column 110 through an outer side surface of the convex column 110. Specifically, the diameter of the boss 110 gradually increases in a direction toward the abutment surface.

In the single-key slot broaching machine, one end of the supporting seat 100, which is far away from the convex column 110, is mounted on a workbench, so as to realize the mounting of the angular positioning tool 10 on the workbench. When the single-key slot broaching machine is placed on a horizontal plane. The protruding column 110 is located at the upper end of the supporting seat 100, and the supporting surface is an upward horizontal surface on the supporting seat 100.

The adjustment mechanism 200 includes two threaded adjustment members 210 and an adjustment block 220. Two screw adjusters 210 are spaced apart and oppositely disposed in a second direction 40 perpendicular to the first direction 30 and mounted on the support base 100.

Each threaded adjustment member 210 is operable to move in a direction toward or away from the other threaded adjustment member 210 until the adjustment block 220 is clamped between the two threaded adjustment members 210 or the adjustment block 220 is separated from the threaded adjustment members 210. The screw adjusting member 210 may be a standard member such as a bolt, a screw, or a screw rod 211, or may be another member having an external screw thread on an outer wall thereof.

The angular positioning mechanism 300 comprises a mounting frame 310 mounted on the adjusting block 220, an angular positioning member 320 with a positioning ball 321 at one end, and an elastic member 330.

The elastic member 330 provides an elastic force for driving the angular positioning member 320 to move in a direction toward the central axis of the boss 110, so as to clamp the positioning ball 321 in the outer tooth socket of the disk gear 20 on the boss 110. The elastic member 330 may be a spring, a metal elastic sheet, or the like.

When the single-key slot bench is placed on a horizontal plane, the first direction 30 is a vertical direction perpendicular to the horizontal plane, and the second direction 40 are horizontal directions perpendicular to each other.

When the angular positioning tool 10 is required to be used for clamping and positioning the disc gear 20 to be processed on the single-key groove broaching machine, the disc gear 20 is sleeved on the convex column 110 so as to position the disc gear 20 in the horizontal plane; the disk gear 20 then falls under its own weight on the abutment surface to position the height position of the disk gear 20 with the abutment surface; under the action of the elastic force provided by the elastic element 330, the angular positioning element 320 has a tendency to move towards the central axis direction of the convex column 110 along the third direction 50, so as to clamp the positioning ball 321 into any one of the external tooth grooves of the disk gear 20 and abut against two side surfaces of the external tooth groove, thereby realizing the angular positioning of the disk gear 20, and completing the clamping and positioning work of the disk gear 20 on the angular positioning tool 10.

When the single-keyway broaching machine is used for broaching the disk gear 20 on the angular positioning tool 10, the broaching tool passes through the tool passing channel 120, and the broaching tool passes through the opening of the tool passing channel 120 on the outer side surface of the convex column 110 to carry out broaching on the inner hole of the disk gear 20 through the feeding operation.

For ease of understanding, the application of the angular positioning member 320 to batch processing of the disk gears 20 is briefly described as follows:

(1) Selecting a disk gear 20 as a sample, clamping the sample on an angularly positioned workpiece, and broaching the sample by using a single-key slot broacher to obtain a key slot on an inner hole of the sample;

(2) Measuring an offset angle between a key groove on the sample and the contour center of the external tooth groove, and judging whether the offset angle meets the angular requirement of the key groove relative to the contour center of the external tooth groove;

(3) If the offset angle meets the design requirement, the angle positioning piece is not required to be adjusted, and other disk gears 20 in the same batch can be directly clamped and positioned on the angular positioning tool 10 for broaching in sequence;

(4) If the offset angle does not meet the design requirement and the designed angle requirement exists between the key groove and the contour center of the outer tooth groove, the angle difference value and the offset direction between the offset angle and the designed angle need to be calculated and obtained, and then the adjustment displacement and the adjustment direction of the adjustment block 220 in the third direction 50 are calculated and obtained according to the angle difference value, the offset direction and the like;

(5) Screwing out the threaded adjusting members 210 positioned in front of the adjusting direction along the direction away from the adjusting block 220 to loosen the adjusting block 220, pushing the adjusting block 220 to move along the adjusting direction in the third direction 50 by a worker to adjust the displacement in the step (4), and screwing both the threaded adjusting members 210 along the direction towards the adjusting block 220 until the two threaded adjusting members 210 respectively abut against the two ends of the adjusting block 220 to position the adjusting block 220 in the third direction 50, so that the adjustment of the angular positioning member 320 can be realized;

(6) And directly clamping and positioning other disk gears 20 in the same batch with the sample on the angular positioning tool 10 so as to facilitate the single-key groove broaching machine to broach the other disk gears 20 in the batch, thereby well meeting the angular requirement of key grooves on the inner holes of the disk gears 20.

Therefore, in the batch processing of the disk gears 20, the setting of the angular positioning tool 10 only needs to adjust the angular positioning angle after the processing of the first disk gear 20, and then the angular positioning angle is not needed to be adjusted again before the processing or during the clamping and positioning of other disk gears 20 in the same batch, so that the key slot on the inner hole of the other disk gears 20 in the same batch can meet the angular requirement relative to the contour center of the outer tooth slot, the clamping and positioning time in the batch processing of the disk gears 20 is greatly saved, and the processing efficiency and the processing precision stability of the disk gears 20 in the batch processing are improved.

Of course, in order to verify whether the angular positioning tool 10 after performing the step (5) can ensure that the positioned bevel gear 20 can obtain the key slot meeting the design requirement, the above step (4) may also be performed back to ensure the adjustment accuracy of the angular positioning tool 10 and the processing accuracy of the subsequent processing of other bevel gears 20 in the same batch, but this is not required in the processing of general bevel gears 20.
