Description
Technical field
The present invention relates to mechanism, be a kind of puller.
Background technology
In machine-building, when needing dismounting to be press-fitted to part together, prior art is to utilize spanner to clamp residence
The part that need to dismantle, then uses hammer stroke spanner, is disassembled from being press-fitted axle by part, this method for dismounting, in dismounting
During there will be the following defect: 1., dismounting speed slow.2. in unloading process, owing to being that spanner clamps part,
Therefore the outer surface being disassembled part easily crushes, and even damages.3. in unloading process, owing to being that spanner clamps part,
When firmly hitting spanner and dragging the part being disassembled, due to unbalance stress, the most easily make the part being disassembled to some side
To skew, the part being disassembled then is caused to disassemble.In order to overcome the problems referred to above, the following a kind of puller of special offer
Solve problem.
Summary of the invention
Do not make the part being disassembled injured or damage when the present invention is to provide a kind of convenient disassembly, simple in construction, dismounting
A kind of puller.It is achieved by: as it can be seen, when needs are pulled down part (155) from axle (516), at this moment, just
Utilize this puller, first the first drag hook (145) and second drag hook (165) of puller are caught on split part (155)
Bottom surface, then withstands the upper surface of axle (516) by the top of traction screw (185), after the good split part of fastening to be regulated, uses hands
Work rotates handwheel (115), and then traction screw (185) rotates also with handwheel (115), due to the rotation of traction screw (185),
Becoming engagement to be connected due to pull bar (175) with traction screw (185) again, the rotation of traction screw (185) forces pull bar (175)
Screw thread along traction screw (185) moves up, and then pull bar (175) drives the first drag hook (145) and the second drag hook (165) also
Move up with pull bar (175), during this moves, owing to the first drag hook (145) and the second drag hook (165) are to catch on
It is disassembled part (155) bottom surface, is then disassembled part (155) and separates with axle (516) along axle (516) upward sliding.One
Planting puller, it provides the benefit that: its simple in construction, easily manufactured, and it is when dismounting separates part simultaneously, and part will not be subject to
Damage, on pull bar (175), be provided with several grooves (125) simultaneously, adapt to the part dismounting varied in size.A kind of puller, solves
Determine the part being press-fitted to together, it is impossible to the problem of dismounting, solved such as used spanner holding parts, then use hammer stroke spanner
When dismantling part, the part being disassembled is injured, or the problem that dismounting is not got off.
A kind of puller, is characterized in that: it is by handwheel (115), traction screw (185), pull bar (175), the first drag hook
(145), the second drag hook (165), drag hook support shaft (135) constitute, described handwheel (115) is fastenedly connected with traction screw (185),
The outer surface of described handwheel (115) is provided with several teeth, and described handwheel (115) can be configured as hexagon, in order to during dismounting, uses
Spanner clamps handwheel (115) and produces bigger revolving force, and described traction screw (185) becomes screw-threaded engagement even with pull bar (175)
Connecing, the front end of traction screw (185) is arranged to cone, and during work, traction screw (185) withstands the end face of axle (516), described
The two ends of pull bar (175) offer transverse concave groove, are provided with the first drag hook (145) and the second drag hook (165) in transverse concave groove,
Described first drag hook (145) and the second drag hook (165) and drag hook support shaft (135) secure fit, described pull bar is offered on (175)
Several grooves (125), drag hook support shaft (135) are had to be flexibly connected with groove (125), described first drag hook (145) and second
Drag hook (165) is arranged to " 7 " font, and during work, the hook of the first drag hook (145) and the second drag hook (165) catches on and is disassembled zero
The lower plane of part (155).
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this puller is further illustrated
Shown in figure:
Fig. 1 is the schematic diagram during work of a kind of puller.
In figure, numeral numbering represents respectively:
115 handwheel 125 groove 135 drag hook support shafts
145 first drag hooks 155 are disassembled part 516 axle
165 second drag hook 175 pull bar 185 traction screws
Detailed description of the invention:
Being illustrated as a kind of puller, operation principle and structure to it connect detailed description below.
One, structure connect: it by handwheel (115), traction screw (185), pull bar (175), the first drag hook (145), second
Drag hook (165), drag hook support shaft (135) are constituted, and described handwheel (115) is fastenedly connected with traction screw (185), described handwheel
(115) outer surface is provided with several teeth, and described handwheel (115) can be configured as hexagon, in order to during dismounting, clamps with spanner
Wheel (115) of stopping produces bigger revolving force, and described traction screw (185) becomes screw-threaded engagement to be connected with pull bar (175), draws spiral shell
The front end of bar (185) is arranged to cone, and during work, traction screw (185) withstands the end face of axle (516), described pull bar (175)
Two ends offer transverse concave groove, transverse concave groove is provided with the first drag hook (145) and the second drag hook (165), described first
Drag hook (145) and the second drag hook (165) and drag hook support shaft (135) secure fit, described pull bar offers several on (175)
Groove (125), drag hook support shaft (135) is flexibly connected with groove (125), described first drag hook (145) and the second drag hook (165)
Being arranged to " 7 " font, during work, the hook of the first drag hook (145) and the second drag hook (165) catches on and is disassembled part (155)
Lower plane.
Two, operation principle is: when needs are pulled down part (155) from axle (516), first draw the first of puller
Hook (145) and the second drag hook (165) catch on the bottom surface of split part (155), then the top of traction screw (185) are withstood axle
(516) upper surface, after the good split part of fastening to be regulated, rotates handwheel (115) by hand, and then traction screw (185) is also
Along with handwheel (115) rotates, due to the rotation of traction screw (185), it is into traction screw (185) due to pull bar (175) again
Engagement connects, and the rotation of traction screw (185) forces pull bar (175) to move up, then along the screw thread of traction screw (185)
Pull bar (175) drives the first drag hook (145) and the second drag hook (165) also to move up with pull bar (175), in this mistake moved
Cheng Zhong, is disassembled part (155) bottom surface owing to the first drag hook (145) and the second drag hook (165) catch on, is then disassembled zero
Part (155) separates along axle (516) upward sliding with axle (516).When the part needing dismounting to vary in size, can draw first
Hook (145) and the second drag hook (165) are adjusted in the groove (125) of the upper diverse location arranged of pull bar (175), in order to dismounting is not
Part with size.
