Abstract

The utility model provides a kind of shaft coupling drawbench, comprises pulling claw, it is characterized in that: also comprise screw jack, push rod, screw mandrel, pulling claw axle sleeve and pulling claw connecting rod; Described screw jack comprises piston boit and is coated at the sleeve of piston boit outside; There is axial through hole described screw mandrel inside, and described push rod is arranged in described through hole; Push rod is fixedly connected with piston boit, and screw mandrel is fixedly connected with sleeve; Described pulling claw axle sleeve is enclosed within outward on screw mandrel, is connected with wire rod thread; Described pulling claw connecting rod one end and pulling claw axle sleeve are hinged, and the other end and pulling claw are hinged.This drawbench is simple in structure, flexible operation and applied widely.

Description

A kind of shaft coupling drawbench
Technical field
The utility model relates to motor, speed reducer coupling dismantling technology field, is specifically related to a kind of shaft coupling drawbench.
Background technology
The dismounting of motor, speed reducer coupling is the work often running in maintenance.The shaft coupling extracting tool using at present, uses draw horse and the hydraulic jack of three claws or two claw compositions to be used in conjunction with, and has two kinds of split type and integral types, and split type operation is more complicated, and integral type is difficult to be applicable to the object of sizes and dismantles.And, due to tolerance fit problem, easily there is shaft coupling and pull out to get off in no matter split type or integral type; Or hydraulic jack overload, situation about all hydraulic cylinder can be damaged.
Utility model content
The utility model provides the shaft coupling drawbench of a kind of flexible operation, applied widely, easy to carry, integrative-structure.
The technical solution of the utility model is: a kind of shaft coupling drawbench, comprise pulling claw, and it is characterized in that: also comprise screw jack, push rod, screw mandrel, pulling claw axle sleeve and pulling claw connecting rod; Described screw jack comprises piston boit and is coated at the sleeve of piston boit outside; There is axial through hole described screw mandrel inside, and described push rod is arranged in described through hole; Push rod is fixedly connected with piston boit, and screw mandrel is fixedly connected with sleeve; Described pulling claw axle sleeve is enclosed within outward on screw mandrel, is connected with wire rod thread; Described pulling claw connecting rod one end and pulling claw axle sleeve are hinged, and the other end and pulling claw are hinged.
Described pulling claw has 3.
On described pulling claw, have at least two installing holes, described pulling claw connecting rod is by installing hole and pulling claw hinge.
Shaft coupling drawbench of the present utility model, pulling claw axle sleeve rotarily drives pulling claw and moves upward at screw axis on screw mandrel, increase the length range of pulling claw operation, and multiple installing holes on pulling claw, different installing holes and pulling claw connecting rod link can further increase the length range of pulling claw operation; The mode that pulling claw is connected with pulling claw axle sleeve by pulling claw connecting rod makes this drawbench storage convenient, and can change the aperture of pulling claw, makes drawbench of the present utility model applied widely.Adopt and screw jack coupling, integral structure, simple in structure, easy to operate and flexible.
Brief description of the drawings
fig. 1the structural representation of a kind of shaft coupling drawbench of the present utility model.
Detailed description of the invention
With detailed description of the invention, scheme of the present utility model is described further by reference to the accompanying drawings.
A shaft coupling drawbench as shown in Figure 1, comprises screw jack 1, push rod 2, screw mandrel 3, pulling claw axle sleeve 4, pulling claw connecting rod 5 and three pulling claws 6; There is screw thread screw mandrel 3 outsides, and inside is axial through hole, and is socketed in push rod 2 outsides by this through hole, and the piston boit 7 of push rod 2 one end and screw jack 1 welds; Screw mandrel 3 welds with the sleeve 8 of screw jack 1.There is the screw thread matching with screw mandrel 3 outsides pull bar axle sleeve 4 inside, can on screw mandrel 3, rotatablely move.Pulling claw 6 has multiple installing holes 9 on the different position of length direction, and one end of pulling claw connecting rod 5 is by installing hole and pulling claw 6 hinges, the other end and pulling claw axle sleeve 4 hinges.
When operation, push rod 2 withstands on the axle of reductor or motor, the calibration that is rotated and regulate by pulling claw connecting rod 5 three pulling claws 6 by adjusting yoke axle sleeve 4 on screw mandrel 3, makes three pulling claws 6 clamp shaft coupling, then completes the field-strip of shaft coupling by operation screw jack 1.
