Detailed Description

The utility model will now be described in detail with reference to the drawings and examples.

Examples

The utility model provides an automatic clamping shell disassembling tool, as shown in figures 1-2, which comprises a base 1, wherein two supporting rods 2 are fixed on the base 1, bolt holes are further formed in the base 1, and the lower shell of an air turbine starter is fixed on the base through the bolt holes and fixing bolts 18;

the support rod 2 is provided with a slide plate 4 and a beam 7, the slide plate 4 can slide up and down along the support rod 2, and the beam 7 is fixed at the top ends of the two support rods through bolts;

the connecting seat 5 is fixed on the sliding plate 4 through the inner hexagon head bolt 9, the two pull grippers 12 are fixed on the sliding plate 4 through the fixing pins 14, the fixing pins are in clearance fit with the pull grippers, the lower end of the pull grippers 12 penetrates through the sliding plate, and the upper end of the pull grippers is positioned in the connecting seat 5;

the ejector rod 13 passes through the sliding plate 4, a compression spring 17 is arranged on the ejector rod 13, the compression spring 17 is positioned below the sliding plate 4, a ∅ shaft retainer ring 15 is arranged on the ejector rod 13 at the upper end of the sliding plate 4 to limit the position, and the ejector rod 13 is ensured not to be ejected by the compression spring 17 in an unoperated state;

the beam 7 is provided with a threaded hole, the compression screw 8 passes through the threaded hole on the beam 7, and the lower end of the compression screw passes through the inner hole of the gland 11 and is limited by a ∅ shaft retainer ring 10; the gland 11 is fixed on the connecting seat 5 through an inner hexagon head bolt 9;

the lower ends of the pull grabs 12 are respectively fixed with an extension spring 16, and one end of each extension spring 16 is fixed on the sliding plate 4; the stretching spring 16 enables the lower end of the pulling grab 12 to be in an open position in an unoperated state, and simultaneously enables the upper end of the pulling grab 12 to be attached to the conical surface of the upper end of the ejector rod 13.

As shown in fig. 6, the upper end of the ejector rod 13 is a conical surface and is provided with a clamping groove, and the upper end of the pull gripper can be clamped during operation; the lower end of the ejector rod is in a boss structure and is used for supporting the compression spring 17 and limiting the falling of the upper shell of the air turbine starter.

In the above embodiment, the dismounting tool is in the position of fig. 4 when the pull gripper 12 is in operation, the lower flange 32 of the air turbine starter is fixed on the base, and the lower housing is limited to move up and down by the fixing bolts 18. As the compression screw 8 rotates downwards, the slide plate 4 gradually moves downwards, after the upper flange 31 of the air turbine starter contacts the ejector rod 13, the ejector rod 13 is jacked up, and meanwhile, the conical surface at the upper end of the ejector rod 13 pushes the pull grab 12 upwards, so that the lower end of the pull grab 12 is gradually tightened, and when the upper end of the pull grab 12 slides into the clamping groove of the ejector rod 13, the compression screw 8 stops rotating downwards, and at the moment, the pull grab 12 reaches the position shown in fig. 5.

When the disassembly tool reaches the position shown in fig. 5, the compression screw 8 rotates upwards to drive the pull gripper 12 to gradually separate the upper shell from the lower shell of the air turbine starter, and when the pull gripper 12 drives the upper shell of the air turbine starter to move upwards, the lower end has a trend of opening towards two sides, but because the upper end is in the clamping groove of the ejector rod 13, the upper end cannot continuously shrink inwards, so that the lower end of the pull gripper cannot be opened to firmly grip the upper shell. After the upper shell is separated along with the pull grab 12, the upper shell cannot fall easily under the limit of a boss at the lower end of the ejector rod 13 and the pull grab, so that the upper shell is protected.

After the work is finished, the lower end of the pulling grip 12 is continuously tightened manually, the ejector rod 13 is separated from the upper end of the pulling grip 12 under the action of the compression spring 17, and after the hand is released, the pulling grip 12 is restored to the position shown in fig. 4 under the action of the tension spring 16.
