Description
Technical field
The present invention relates to a kind of helical spring gum cover adhesion testing instruments, for examining gum cover on automotive suspension spring
Whether adhesion is qualified.
Background technology
Automotive suspension spring is the flexible member in automotive suspension, can be born by automotive suspension spring, transmit vertical
Load, makes to make elastic connection between vehicle bridge and vehicle frame or vehicle body, and then relaxes and suppress the impact caused by uneven road surface, therefore
The effect of automotive suspension spring is quite crucial.
But in actual application, that is, after being assemblied on car body, the automotive suspension spring of some design structures, such as spiral shell
Spring is revolved, noise can be produced in vehicle traveling process, in order to abate the noise, automobile factory is typically required in one end of bearing spring
Portion or both ends increase gum cover.
At present, connected mode conventional between gum cover and spring is that this requires gum cover and spring using PUR adhesion
Between have certain adhesion.But because of the domestic measuring means to above-mentioned adhesion without standard, therefore, each producer's life at present
The adhesion property of gum cover is different in the spring of output, and some can be smaller because of adhesion, cause the later stage when applying gum cover transported in entrucking
The problem of deviating from during dynamic, it is impossible to reach the purpose of initial noise reduction.
The content of the invention
According to deficiency of the prior art above, the technical problem to be solved in the present invention is：One kind is provided and can verify that glue

Helical spring.
It is preferred that, described pressing plate is made up of vertical fixed plate body and horizontal pressing plate body of integral forming process.
It is preferred that, the cross section of described supporting plate is that circle, i.e. supporting plate are a major axis, and such helical spring is mounted in branch
When on fagging, hard collision will not be produced, so as to effectively protection helical spring.
It is preferred that, described counterweight body is provided with connection ring, and lower end and the connection ring of hook are hinged, and counterweight will be examined to hook
Outside helical spring during hanging hole on gum cover, the angle that can be linked up with according to hanging hole position flexible modulation.
It is preferred that, pallet and elevating mechanism are set up, elevating mechanism is arranged on base, and pallet is fixed on the upper of elevating mechanism
End, examines counterweight to be placed on pallet, the automatic lifting for examining counterweight is realized by elevating mechanism, without manually lifting inspection weight
Code, it is to avoid operating personnel are examined counterweight and the potential safety hazard such as injure by a crashing object.In actual application, risen to suitably when examining counterweight
After height, hook is hooked on the hanging hole of gum cover, then drives pallet to move down a little distance by elevating mechanism, makes inspection counterweight firm
Just depart from pallet, so during whole gum cover adhesion verification test, even if because gum cover adhesion is undesirable
Cause to examine counterweight to drive gum cover to come off, examine counterweight also to fall on pallet, either examined to operating personnel or entirely
Instrument (counterweight body or base etc.) can play effective protective action.
It is preferred that, described elevating mechanism uses hydraulic cylinder, and cylinder body is fixed on base, and cylinder rod top is fixed with pallet to be connected
Connect, be able to ensure that inspection counterweight is steadily lifted by hydraulic cylinder.
It is preferred that, the outward flange of described pallet is higher than its interior card, in use, ensuring to examine counterweight to be located at the interior of pallet
In card.
It is preferred that, the top of described pallet is provided with rubber blanket, causes to examine weight when gum cover adhesion is undesirable
When code drive gum cover comes off, the rubber blanket on pallet can provide resilient support, effectively prevent between counterweight body and pallet
Hard collision, while the noise produced during the two collision can be reduced.It is further preferred that the thickness of described rubber blanket is
5mm~20mm.
The present invention is had an advantageous effect in that compared with prior art：
The adhesion between gum cover and helical spring can effectively be examined by the present invention, it is ensured that gum cover and spiral
Adhesion property between spring, it is to avoid the problem of deviating from because of adhesion brought gum cover not up to standard in entrucking motion process,
Noise in reduction vehicle traveling process that can be permanently effective produced by automotive suspension spring.
