Abstract
The utility model discloses a kind of spring elongations to test special carrier, including fixing seat, screw rod, pressure plate, nut, one piece of pressure plate is laid in the fixing seat, pressure plate is equipped with the threading groove for running through pressure plate upper and lower ends, threading groove side extends to the side wall and opening of pressure plate, a screw rod straight up is fixed in the fixing seat, screw rod penetrates pressure plate, and a nut is screwed on screw rod.The utility model is easy to use by the way that threading groove setting on pressure plate, so that spring can be fixed effectively, and is suitable for the spring of different windings.
Description
[technical field]
The utility model relates to the technical fields of spring, the especially technical field of spring elongation test special carrier.
[background technique]
Spring be it is a kind of utilize elasticity come work machine components.The part made of elastic material is sent out under external force
Raw deformation restores to the original state again after removing external force.Generally it is made of spring steel.The complicated multiplicity of the type of spring, by shape point, mainly
There are helical spring, scroll spring, flat spring, heterotypic spring etc..Existing spring needs to inspect by random samples after processing is completed completion and stretches
Test.Existing extension test collet clamping effect is not ideal enough, and is easy to make spring distortion.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of spring elongation test exclusive clamps
Head can be such that spring is effectively clamped, and spring is not easy to distort.
To achieve the above object, the utility model proposes a kind of spring elongations to test special carrier, including fixing seat, spiral shell
Bar, pressure plate, nut, lay one piece of pressure plate in the fixing seat, and pressure plate is equipped with one through pressure plate up and down two
The threading groove at end, threading groove side extend to the side wall and opening of pressure plate, and one is fixed in the fixing seat straight up
Screw rod, screw rod penetrates pressure plate, a nut is screwed on screw rod.
Preferably, the pressure plate is in the form of annular discs, threading groove is directed toward the center of circle of pressure plate.
Preferably, the nut top is fixed, there are two auxiliary blocks, and two auxiliary blocks are located at the two sides of screw rod, auxiliary
It helps block to be equipped with the horizontally disposed through-hole through auxiliary block, dismountable auxiliary rod is inserted on through-hole, auxiliary pole length is greater than pressure
The diameter of tight plate.
Preferably, the nut bottom is equipped with elastic washer.
The utility model has the beneficial effects that the utility model by by threading groove be arranged on pressure plate so that spring can
It is effectively fixed, and is suitable for the spring of different windings, it is easy to use；Auxiliary block cooperation auxiliary rod is convenient for nut
It tightens and unscrews, so that the use of collet becomes more convenient；The setting of elastic washer is so that pressure plate can be preferably compacted.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of main view of spring elongation test special carrier of the utility model；
Fig. 2 is a kind of top view of spring elongation test special carrier of the utility model.
In figure: 1- fixing seat, 2- pressure plate, 3- nut, 10- screw rod, 20- threading groove, 30- elastic washer, 31- auxiliary
Block, 32- through-hole, 33- auxiliary rod.
[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of spring elongation of the utility model test special carrier, including fixing seat 1, screw rod 10, pressure
Tight plate 2, nut 3 lay one piece of pressure plate 2 in the fixing seat 1, and pressure plate 2 is equipped with one and runs through pressure plate about 2 two
The threading groove 20 at end, 20 side of threading groove extend to the side wall and opening of pressure plate 2, and one is fixed in the fixing seat 1 and is erected
Straight upward screw rod 10, screw rod 10 penetrate pressure plate 2, a nut 3 are screwed on screw rod 10, and the pressure plate 2 is in the form of annular discs, wears
Wire casing 20 is directed toward the center of circle of pressure plate 2, is fixed at the top of the nut 3 there are two auxiliary block 31, two auxiliary blocks 31 are located at
The two sides of screw rod 10, auxiliary block 31 are equipped with the horizontally disposed through-hole 32 through auxiliary block 31, are inserted on through-hole 32 dismountable
Auxiliary rod 33,33 length of auxiliary rod are greater than the diameter of pressure plate 2, and 3 bottom of nut is equipped with elastic washer 30.
Utility model works process:
During the work time, threading groove 20 is arranged in pressure plate 2 a kind of spring elongation test special carrier of the utility model
On, so that spring can be fixed effectively, and it is suitable for the spring of different windings, it is easy to use；Auxiliary block 31 cooperates auxiliary
Bar 33 is helped to make nut convenient for tightening and unscrewing, so that the use of collet becomes more convenient；The setting of elastic washer 30 so that
Pressure plate 2 can be preferably compacted.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
