Description
Technical field
The present invention relates to pick-up unit, particularly a kind of number of coils pick-up unit.
Background technology
Spring is a kind of mechanical component utilizing elasticity to carry out work.There is deformation under external force with the part that resilient material is made, restore to the original state again after removing external force.The kind complexity of spring is various, and by stressed character, spring can be divided into extension spring, Compress Spring, torsionspring and flexural spring; Disk spring, ring spring, laminated spring, volute spring, valute spring and torsion-bar spring etc. can be divided into by shape, cold coiling spring and hot coiling spring can be divided into by manufacturing process.Common cylinder spring is simple owing to manufacturing, and can make various types according to loading conditions, and structure is simple, therefore most widely used.In general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact flexibility and good heat treatment performance etc., and conventional has carbon spring steel, alloy spring steel, rustproof spring steel and aldary, nickel alloy and rubber etc.
Spring is applied very extensive in mechanical field, and in industry makes, the spring often needing the bridge of the nose to produce has identical characteristic, and this just requires that first spring should have identical parameter.The parameter of a spring can have the number of turns, drift, diameter and pitch to characterize.After spring manufacture or before using, need to measure these parameters, wherein the most important thing is the number of coils.
For spring manufacturing enterprise, the number of turns of spring is one of important indicator whether half section of spring be qualified, therefore first will to test judgement to its number of turns after spring is produced.
By artificial visually examine, inspection at present for the number of coils mainly identifies that whether the number of coils is qualified, subjectivity is too strong, easily occurs makeing mistakes when carrying out checking in enormous quantities, the qualification rate of the spring that can not ensure to dispatch from the factory.And now spring obtains kind is more and more, the height number of turns is different, and shape is also various, and require more and more tighter, depend merely on range estimation error too large, " banana " type, tower spring also accurately cannot measure the number of turns on platform.If a kind of appliance special for detecting joined by each spring, one is cost high two be put, management difficulty is large.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of simple to operate, accuracy of detection is high and the number of coils pick-up unit of highly versatile.
Object of the present invention is achieved through the following technical solutions: a kind of number of coils pick-up unit, it comprises screw, base fixed block, connecting link, set nut, location adjuster bar, moving scale post and positioning dial disc, described connecting link lower end offers screw, screw passes base fixed block and is connected with connecting link, external thread is provided with in the middle part of described connecting link, described adjuster bar lower end, location offers internal thread, and be enclosed within connecting link, on described connecting link, threaded engagement is connected with a set nut, set nut is positioned at adjuster bar lower end, location, described connecting link upper end is set with moving scale post and positioning dial disc, positioning dial disc is positioned on moving scale post upper surface.
Described adjuster bar upper end, location symmetry offers two cat's paws.
Described moving scale post is made up of two cones, and the large end face of two cones connects in opposite directions, and on the small end face of two cones of described moving scale post, equal symmetry offers a breach, and this breach matches with the cat's paw on the adjuster bar of location.
Described connecting link upper end is one " D " shape post, positioning dial disc offers " D " shape hole coordinated with " D " shape post.
Described moving scale post is provided with horizontal scale.
The present invention has the following advantages: number of coils pick-up unit of the present invention, this device is fixed on the lift seat of different spring, twist and regulate backstay to drive moving scale post by the scale alignment springs upper end tip position on moving scale post, tighten set nut, on moving scale post, longitudinal scale mark angle of aiming on fixing scaleplate accurately can draw the number of turns of spring, and moving scale post is provided with horizontal scale, directly can view the change of spring heights, therefore it have simple to operate, accuracy of detection is high and the advantage of highly versatile.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of number of coils pick-up unit, it comprises screw 1, base fixed block 2, connecting link 3, set nut 4, location adjuster bar 5, moving scale post 7 and positioning dial disc 8, described connecting link 3 lower end offers screw, screw 1 passes base fixed block 2 and is connected with connecting link 3, external thread is provided with in the middle part of described connecting link 3, described location adjuster bar 5 lower end offers internal thread, and be enclosed within connecting link 3, on described connecting link 3, threaded engagement is connected with a set nut 4, set nut 4 is positioned at adjuster bar 5 lower end, location, described connecting link 3 upper end is set with moving scale post 7 and positioning dial disc 8, positioning dial disc 8 is positioned on moving scale post 7 upper surface.
In the present embodiment, as shown in Figure 2, described location adjuster bar 5 upper end symmetry offers two cat's paws 9, moving scale post 7 is made up of two cones, and the large end face of two cones connects in opposite directions, as shown in Figure 3 and Figure 4, on the small end face of two cones of described moving scale post 7, equal symmetry offers a breach 6, this breach 6 matches with the cat's paw 9 on the adjuster bar 5 of location, rotating location adjuster bar 5 will drive moving scale post 7 to rotate, moving scale post 7 arranges two different cones, for mean diameter of coil and path drop large, moving scale post 7 directly turns around just passable.Moving scale post 7 is provided with horizontal scale, and the effect of the horizontal scale on moving scale post 7 is: in the coiling process of spring, and operator very directly just can see height change when the measurement number of turns in process of production.Cone is heightened extremely close to the little end position of spring, spring inside diameter little or cut off back ditch also can Timeliness coverage.As long as the different cone of producer two or three is just enough.
In the present embodiment, described connecting link 3 upper end is one " D " shape post, as shown in Figure 5, positioning dial disc 8 offers " D " shape hole coordinated with " D " shape post, positioning dial disc 8 can not rotate around " D " shape post, and moving scale post 7 can rotate around " D " shape post.
The course of work of the present invention is as follows: be connected to required spring by screw 1 and base fixed block 2 and fall in journey, twist location adjuster bar 5, the scale alignment springs upper end tip position that location adjuster bar 5 drives moving scale post 7 to make on moving scale post 7, tighten set nut 4, check that on moving scale post 7, longitudinal scale mark aims at the angle on fixing index dial 8, the number of turns of spring can be drawn, the present invention is to tower spring, conical coil spring is all practical with " banana " type spring, for the lift seat that often kind of spring is different, as long as this device is fixed on different lift seats just accurately the number of coils can be detected.
