Abstract
A tool structure for disintegrating a spiral lock ring is characterized by comprising a lock ring sleeve, a front end sleeve, a rear end sleeve, a spring and an ejector rod, wherein the opening end of the lock ring sleeve faces forward, the bottom end of the lock ring sleeve is fixedly connected with the front end sleeve which is connected with the rear end sleeve, and the ejector rod penetrates through the spring to be installed in the front end sleeve and the rear end sleeve. The lock ring sleeve is of a cylindrical-barrel-shaped structure as a whole and comprises a sleeve wall and a guide block, wherein the guide block is of a block-shaped structure provided with an inclined face and arranged in the sleeve wall. The tool structure for disintegrating the spiral lock ring has the advantages that the disintegrating problem of the spiral lock ring is solved, and the spiral lock ring, a commonly-used structure, is made to be more widely used and be free of limitations of space and size; meanwhile, the tool improves the efficiency and more importantly does not rely on experience and capability of workers.
Description
Technical field
The utility model relates to the disassembling tool structure of screw type retainer on the aero-engine, particularly a kind of disassembling tool structure of screw type retainer.
Background technology
The screw type retainer is a kind of part that often uses in the aero-engine, and its effect is locking nut, prevents that nut from getting loose.Its decomposition principle be by the rotating screw retainer with the retainer reduced, it is decomposited in the gutter.
Decomposition method in the at present aero-engine assembling industry all is manual mode, the large or larger spiral retainer of retainer diameter for the space, and mounting or dismounting are than being easier to.But the decomposition of this screw type retainer is just very difficult in following two kinds of situations: narrow space is limited by structure space, the unreachable position of staff or can reach the position reluctantly; The retainer diameter is less, causes retainer elasticity very large, thereby the strength deficiency of staff is so that the retainer reduced reaches the purpose of decomposition.When above situation occurring, the decomposition of screw type retainer relies on personal experience and ability mainly by veteran experienced operator, wastes time and energy, and finally also might adopt destructive is olation.Because the retainer diameter is little, the large elasticity of the hardness of retainer is little, decompose difficulty, and the loss of retainer is serious.
The utility model content
The purpose of this utility model is in order to simplify the operation, and saves man-hour, and the spy provides a kind of disassembling tool structure of screw type retainer.
The utility model provides a kind of disassembling tool structure of screw type retainer, it is characterized in that: the disassembling tool structure of described screw type retainer comprises retainer sleeve 1, front end sleeve 2, rear end sleeve 3, spring 4, push rod 5;
Wherein: retainer sleeve 1 openend forward, the bottom of retainer sleeve 1 and front end sleeve 2 are connected, front end sleeve 2 is connected with rear end sleeve 3, push rod 5 passes spring 4 and is installed in front end sleeve 2 and the rear end sleeve 3.
Described retainer sleeve 1 integral body is the cylinder barrel-like structure, comprises barrel 101 and bootstrap block 102, and bootstrap block 102 is arranged in barrel 101 inside for being with bevelled block structure.
Described bootstrap block 102 numbers are 2～9.
With screw type retainer compression, when its maximum outside diameter during less than the axle internal diameter, retainer is stayed in the retainer sleeve 1, takes out with retainer sleeve 1 by bootstrap block 102.
Advantage of the present utility model:
The disassembling tool structure of screw type retainer described in the utility model has solved the resolution problem of screw type retainer, and this locking mechanism commonly used of screw type retainer can be more widely used, and no longer is subjected to the limitation of space and size.This frock not only is embodied in and raises the efficiency simultaneously, the more important thing is that it does not rely on workman's experience and ability.
Description of drawings
Below in conjunction with drawings and the embodiments the utility model is described in further detail:
Fig. 1 is the disassembling tool structural principle structural representation of screw type retainer;
Fig. 2 is retainer sleeve schematic diagram.
The specific embodiment
Present embodiment provides a kind of disassembling tool structure of screw type retainer, it is characterized in that: the disassembling tool structure of described screw type retainer comprises retainer sleeve 1, front end sleeve 2, rear end sleeve 3, spring 4, push rod 5;
Wherein: retainer sleeve 1 openend forward, the bottom of retainer sleeve 1 and front end sleeve 2 are connected, front end sleeve 2 is connected with rear end sleeve 3, push rod 5 passes spring 4 and is installed in front end sleeve 2 and the rear end sleeve 3.
Described retainer sleeve 1 integral body is the cylinder barrel-like structure, comprises barrel 101 and bootstrap block 102, and bootstrap block 102 is arranged in barrel 101 inside for being with bevelled block structure.
Described bootstrap block 102 numbers are 2.
With screw type retainer compression, when its maximum outside diameter during less than the axle internal diameter, retainer is stayed in the retainer sleeve 1, takes out with retainer sleeve 1 by bootstrap block 102.
Present embodiment provides a kind of disassembling tool structure of screw type retainer, and overall structure is similar to Example 1, and the difference part is that described bootstrap block 102 numbers are 5.
Present embodiment provides a kind of disassembling tool structure of screw type retainer, and overall structure is similar to Example 1, and the difference part is that described bootstrap block 102 numbers are 9.
