[0029] Embodiment 1

[0030] The present embodiment proposes a special-shaped gear machining chuck, like Figure 1As shown, including the card seat 1, the center of the card seat 1 is provided with a placement slot 2, the placement slot 2 is placed in the special-shaped toothless gear, the preliminary positioning is carried out, so as to carry out clamping. The top of the card seat 1 is fixedly installed with three blocks 4.

[0031] As shown in the figure, Figures 2 to 4 The top of the card seat 1 is provided with a tooth engagement part 3, the tooth engagement part 3 includes an arc-shaped sliding groove 31, a sliding block 32, a pushing table and a clamping claw 36, the top of the card seat 1 is provided with a plurality of arc-shaped sliding grooves 31, the plurality of arc-shaped sliding grooves 31 are distributed in a ring shape, the arc-shaped sliding groove 31 of the top of the card seat 1 is slidably connected with the sliding block 32, the side of the sliding block 32 away from the card seat 1 is provided with a pushing table, the side of the pushing table away from the sliding block 32 is slidably connected with the clamping claw 36, and the clamping claw 36 is engaged with the special-shaped toothless gear.

[0032] By sliding the sliding block 32 in the arc-shaped sliding groove 31, the position of the clamping claw 36 is adjusted, so that the clamping claw 36 moves to the tooth position of the special-shaped toothless gear, so that the plurality of clamping claws 36 can clamp the special-shaped toothless gear, and the clamping claw 36 is located in the toothless position of the special-shaped toothless gear, and cannot be clamped. The end of the clamping claw 36 adopts an M-shaped structure, and the clamping claw 36 clamps one tooth on the special-shaped toothless gear, so as to clamp the special-shaped toothless gear

[0033] The pushing table includes a sliding plate 35 and a parallel table, the sliding plate 35 slides along the parallel table, the parallel table is fixedly installed on the top of the sliding block 32, and the clamping claw 36 slides on the top of the sliding plate 35. By sliding the clamping claw 36 on the sliding plate 35, the distance between the clamping claw 36 and the special-shaped toothless gear is adjusted to adapt to special-shaped toothless gears of different sizes.

[0034] As shown in the figure, Figure 3 And Figure 4 The top of the sliding plate 35 is provided with a strip-shaped sliding groove 38, the clamping claw 36 slides in the strip-shaped sliding groove 38, a limiting block is fixedly installed in the strip-shaped sliding groove 38, the maximum moving distance of the clamping claw 36 is limited, and the position of the clamping claw 36 is fixed, so that the clamping claw 36 can provide stable clamping force when clamping the teeth of the special-shaped toothless gear. The inside of the strip-shaped sliding groove 38 is fixedly installed with a reset spring 37 with a switch installed at the end, the reset spring 37 is located on the moving path of the clamping claw 36, the inside of the sliding block 32 is rotatably connected with a displacement gear 33, the arc surface of the arc-shaped sliding groove 31 is fixedly installed with a track tooth 34, the center of the sliding block 32 is fixedly connected with a motor installed in the inside of the sliding block 32, and the motor is electrically connected with the switch.

[0035] The motor drives the slider 32 to move, thereby adjusting the position of the clamping claw 36. When the clamping claw 36 moves and contacts the teeth of the irregularly shaped gear, the clamping claw 36 will be squeezed and moved because the teeth have an inclined surface. The movement of the clamping claw 36 compresses the return spring 37 and forces the switch. Since the switch can only be triggered by being pressed and then released, after the teeth on the irregularly shaped gear move to the center of the clamping claw 36, the return spring 37 resets the clamping claw 36. At this time, the switch turns off the motor, thereby fixing the position of the clamping claw 36 and cooperating with the slide plate 35 to move on the parallel platform to increase the clamping force.

[0036] In this embodiment, the position of the clamping claw 36 is adjusted by sliding the slider 32 in the arc-shaped groove 31, so that the clamping claw 36 moves to the position where there are teeth on the missing gear. The clamping claw 36 is determined by the squeezing displacement of the missing gear teeth. Finally, the clamping force of the clamping claw 36 is increased by moving the slide plate 35.

[0037] Example 2

[0038] Based on Example 1, this example proposes a chuck for machining irregularly shaped gears, such as... Figure 4 As shown, the end of the gripper 36 is provided with a conversion component 5. The conversion component 5 includes an arc-shaped gripper 52, a bottom block 53 and a top block 54. The top block 54 is fixedly installed at the end of the gripper 36. The side of the top block 54 is rotatably connected to the bottom block 53. The bottom block 53 slides on the top of the slide plate 35. The arc-shaped gripper 52 is fixedly installed at the end of the top block 54.

[0039] A circular groove 51 is formed on the top of the slide plate 35. The circular groove 51 and the strip-shaped slide 38 are interconnected. The bottom block 53 slides within the strip-shaped slide 38. The bottom block 53 has a cube structure, and the diagonal length of the bottom block 53 is smaller than the diameter of the circular groove 51. The bottom block 53 rotates within the circular groove 51. The track tooth 34 rotates within the circular groove 51 to adjust the position of the clamping claw 36 and the slide plate 35. Within the movable range of the clamping claw 36, the missing gear it contacts has no teeth, so the slide plate 35 can be flipped over to fix the missing gear at that position.

[0040] The inner arc surface of the arc-shaped gripper 52 contacts the irregularly shaped missing gear. Initially, the track tooth 34 is located within the strip-shaped groove 38, and the distance between the gripper 36 and the placement groove 2 is shorter than the distance between the arc-shaped gripper 52 and the placement groove 2. Initially, the movement of the gripper 36 is used to determine whether there are teeth on the missing gear within its range of movement. If there are no teeth, the flip slide 35 is flipped.

[0041] In the embodiment, when the clamping jaw 36 is not in contact with the teeth in its moving range, the clamping jaw 36 and the slide plate 35 can be adjusted in position by rotating the track teeth 34 in the circular groove 51, so that the inner arc surface of the slide plate 35 faces the missing tooth gear, and the slide plate 35 fixes the missing tooth gear in position, and different clamping is performed for different positions of the missing tooth gear.

[0042] The above specific embodiments are only several optional embodiments of the utility model, based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make multiple alternative improvements and combinations to the above specific embodiments.
