The utility model discloses a kind of twisting fixtures for leading screw assembling, including clamping part, outrigger shaft, torsion bar and the main force application rod being welded as a whole successively from beginning to end, the clamping part is included for by leading screw end cover cylinder in the inner and for leading screw to be held out against to the screw in cylinder, the screw is installed through by threaded hole on barrel wall, the outrigger shaft and cylinder coaxial arrangement, for the torsion bar perpendicular to outrigger shaft to increase reverse lever, the main force application rod is parallel with outrigger shaft.The twisting fixture of the utility model can be suitable for the circumferentially upper smaller assembly environment in operating space of leading screw, not only laborsaving, and its operation more meets ergonomics.
Description
Technical field
The utility model is related to a kind of fixtures, and in particular to a kind of twisting fixture for leading screw assembling.
Background technology
Leading screw is a kind of common actuated element, is widely used in the device for needing for rotary motion to be converted into linear motion
In equipment, such as lathe, pneumatic system, cooling system, driving motor.When assembling leading screw, it is often necessary to reverse leading screw.Mesh
Before, to reverse leading screw, there are two types of common modes, and one kind is to make its torsion with spanner clamping leading screw end；Another kind is in silk
Thick stick end radially opens up hole, and realizes its torsion by leading screw is pulled in a lever insertion hole.Both modes all need
When wanting rotating spanner or lever, spanner or lever will not interfere with other parts, that is, need leading screw end perimeter have compared with
Big operating space is not suitable for the small assembly environment in the circumferentially upper operating space of leading screw.
Invention content
In view of this, the purpose of this utility model is to provide a kind of twisting fixture for being exclusively used in leading screw assembling, so that
The fixture can be suitable for the smaller assembly environment in operating space.
In order to achieve the above objectives, the utility model provides following technical solution：
A kind of twisting fixture for leading screw assembling, including the clamping part, outrigger shaft, torque being welded as a whole successively from beginning to end
Bar and main force application rod, the clamping part are included for by leading screw end cover cylinder in the inner and for holding out against leading screw in cylinder
Interior screw, the screw are installed through by threaded hole on barrel wall, the outrigger shaft and cylinder coaxial arrangement, the power
For square bar perpendicular to outrigger shaft to increase reverse lever, the main force application rod is parallel with outrigger shaft.
Further, the middle part of the outrigger shaft is also integrally molded auxiliary force application rod, the auxiliary force application rod and torsion bar phase
It is mutually parallel.
The beneficial effects of the utility model are：
The twisting fixture of the utility model can be suitable for the circumferentially upper smaller assembly environment in operating space of leading screw, not only
It is laborsaving, and its operation more meets ergonomics.
Description of the drawings
In order to make the purpose of this utility model, technical solution and advantageous effect clearer, the utility model provides as follows
Attached drawing illustrates：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of cylinder；
Wherein：2- outrigger shafts, 3- torsion bars, the main force application rods of 4-, 5- auxiliary force application rod, 11- cylinders, 12- spiral shells
Nail, 13- ladder holes.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
A kind of twisting fixture for leading screw assembling, referring to Fig. 1, including be welded as a whole successively from beginning to end clamping part, prolong
Stretch axis 2, torsion bar 3 and main force application rod 4, the clamping part is included for by leading screw end cover cylinder 11 in the inner and for will
Leading screw holds out against the screw 12 in cylinder 11, and the screw 12 is installed through by threaded hole on 11 wall of cylinder, the extension
Axis 2 and cylinder 11 are coaxially disposed, and the torsion bar 3 is perpendicular to outrigger shaft 2 to increase reverse lever, and the main force application rod 4 is with prolonging
It is parallel to stretch axis 2.
In specific implementation process, which is packed into after carrying out quenching treatment in the threaded hole, can improve its hardness.
In use, the cylinder of clamping part 11 first is sleeved on leading screw end, tightening screw 12 using pocket wrench makes its clamping
Then leading screw is held main force application rod 4, is rotated centered on making its axis by leading screw, torque is transferred to clamping part by outrigger shaft 2
Act on leading screw.In the twisting fixture of the utility model, due to tightening the volume of spanner needed for screw 12 much smaller than directly torsion
The volume of spanner needed for leading screw can be suitable for the circumferentially upper smaller assembly environment in operating space of leading screw, it is preferable that the screw 12
For soket head cap screw, corresponding spanner volume smaller；It is more effortless by the way that torsion bar 3 is set to increase reverse lever；And main force application rod
4 is parallel with outrigger shaft 2, and can hold with a firm grip after the main force application rod 4 of face force, and operation more meets ergonomics.
In a kind of embodiment of optimization, the middle part of the outrigger shaft 2 is also integrally molded auxiliary force application rod 5, the auxiliary
Force application rod 5 is mutually parallel with torsion bar 3.In use, a hand holds main force application rod 4, another hand holds the auxiliary force application rod
5, auxiliary force application rod 5 shares part torque, more convenient operation, more effortless.
In a kind of embodiment of optimization, referring to Fig. 2,11 inside of cylinder of clamping part is ladder hole 13, in use,
Leading screw end is resisted against on the cascaded surface of the ladder hole 13, and leading screw is stretched into the macropore of ladder hole 13, leading screw end and rank
Tread bottom friction generates frictional resistance, can reduce the stress of screw 12, clamping is more reliable, and outrigger shaft 2 leads to the ladder
The aperture in hole 13 welds again after being connected through a screw thread, and connection is more reliable.
Finally illustrate, preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can in the form and details make it various changes, without departing from the utility model claims book institute
The range of restriction.
