Abstract
The utility model discloses a free turbine fastening screw dismounting tool, which comprises a bottom plate, a clamping seat, a support and a bush, wherein the bottom plate and the support are positioned through a positioning pin and are fixed through screws; the clamping seat is fixed at the center of the bottom plate through a screw, and the support is provided with a lining in an interference fit mode. The removal tool may define and support a free turbine for rotation.
Description
Technical Field
The utility model belongs to the technical field of the frock part, concretely relates to free turbine fastening screw assembly and disassembly tools.
Background
When the free turbine is disassembled and assembled on the gas turbine starter, the rotation of the free turbine needs to be limited, a fastening screw at one end of the free turbine is screwed down or loosened, and a fixed point can only be selected from an open slot at the other end of the turbine shaft. As the length of the free turbine shaft reaches 260mm, a tool is needed, the free turbine can be limited to rotate through an open slot at one end, and meanwhile, the free turbine is reliably supported.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a free turbine fastening screw assembly and disassembly tools can inject the rotation of free turbine to support the free turbine.
The technical scheme of the utility model: a free turbine fastening screw dismounting tool comprises a bottom plate, a clamping seat, a support and a bushing, wherein the bottom plate and the support are positioned through a positioning pin and fixed through screws; the clamping seat is fixed at the center of the bottom plate through a screw, and the support is provided with a lining in an interference fit mode.
The distance between the upper plane of the support and the clamping seat is (256 +/-0.4) mm.
Furthermore, 4 claws matched with one end of the free turbine shaft are arranged on the clamping seat.
Further, the bore diameter of the bushing forms a clearance fit with the shaft of the free turbine.
Further, the coaxiality phi of the inner hole of the bushing and the clamping seat is 0.1 mm.
The utility model has the advantages that: when the clamping device is used, a bush on the support and the free turbine shaft form clearance fit to support and position the free turbine, the distance between the upper plane of the support and the clamping seat is (256 +/-0.4) mm, and the clamping groove at one end of the free turbine shaft is made to just extend into 4 claws of the clamping seat; the coaxiality of the clamping seat and the bush is phi 0.1, and the proper contact position of the claw of the clamping seat and the groove on the free turbine shaft is ensured.
Drawings
FIG. 1 is a sectional view of the vertical surface of the mounting/dismounting tool of the present invention;
fig. 2 is a bottom view of the mounting and dismounting tool of the present invention;
fig. 3 is a schematic view of a use state of the dismounting tool of the present invention.
The reference numbers in the drawings are respectively: 1. bottom plate, 2, M5 screw, 3, cassette, 4, support, 5, bush, 6, M10 screw, 7, locating pin, 8, free turbine (product part), 9, fastening screw (product part).
Detailed Description
The present invention will be described in detail with reference to the accompanying fig. 1 and the embodiments.
Examples
As shown in the figures, the utility model relates to a free turbine fastening screw dismounting tool, which comprises a bottom plate 1, a clamping seat 3 fixed on the central position of the bottom plate 1 through an M5 screw 2, a support 4 fixed on the bottom plate 1 through an M10 screw 6, and a positioning pin 7 for positioning between the bottom plate 1 and the support 4; the support 4 is provided with a bushing 5 in an interference fit manner; the diameter of the inner hole of the bushing 5 is in clearance fit with the shaft of the free turbine 8; the coaxiality phi of the inner hole of the bushing 5 and the clamping seat 3 is 0.1 mm.
In the above embodiment, as shown in fig. 1, the free turbine 8 is inserted into the bushing 5, and the locking slot at one end of the free turbine shaft is aligned with the claw of the clamping seat 3, so that the fastening screw 9 at the other end of the free turbine shaft can be detached by the universal torque wrench.
