The link assembly of the present embodiment can independently be manufactured into product, and it is mainly assembled in the shearing test of the present embodiment
In structure；The shearing test mechanism of the present embodiment can also independently be manufactured into product, and it is mostly installed at cutting for the present embodiment
Cut on test machine.
The shearing test mechanism of the present embodiment described briefly below and the operation principle and process of shear tester.
In through-wall welding structure lead-acid battery production process, " shear pressure " is that the shearing test head of shearing test mechanism is applied
The cross force on two butt-welding fittings is added in, welding quality is more good, " shear pressure " that solder joint can be born is bigger.Produced
Cheng Zhong, using the shearing test mechanism of the present embodiment, can be adjusted to " shear pressure " according to the technological requirement of tested battery
Defined value, for example, 12V7Ah batteries set " shearing force " as 80Kg, 12V14Ah batteries set " shearing force " as 150Kg.It is complete
Into after shearing test, if solder joint completely if judge battery to be qualified, if solder joint cut or have deformation if judge battery as
It is unqualified.
The shearing test mechanism need to be arranged on shear tester when using, and as shown in Figure 4 and Figure 5, surveyed respectively from shearing
The front and back of test-run a machine structure 10 illustrates its state on shear tester 20.
Lifting, switch, source of the gas and the air pressure adjustment of shearing test mechanism 10 are controlled by shear tester 20, use preceding root
According to different batteries regulation spacing, height limit of the workbench of shear tester 20 etc., shearing test mechanism 10 is needed according to current right
The adjusting nut of the width adjustment drive cylinder afterbody of weldment, enables butt-welding fitting to be put into the first portion of shearing test and shearing test
It is first between two, while the adjusting nut on the second Anchor plate kit is also required to do corresponding adjustment.Tune on shear tester 20
The drive cylinder of pressure valve output end connection shearing test mechanism 10 is so as to drive drive cylinder, by adjusting the defeated of pressure regulator valve
The shearing force suitable for battery 30 to be measured can be set by going out air pressure.
As shown in Figure 6 and shown in Fig. 7, before shearing test, the first portion 2-171 of shearing test and first two 2- of shearing test
172 (i.e. shearing test heads) open, and do not apply pressure to the butt-welding fitting of the battery 30 on the workbench of shear tester 20；First
Portable plate and the second portable plate are in the two ends of shearing test mechanism 10, apart from each other.
As shown in Figure 8 and shown in Fig. 9, during shearing test, technical staff presses switch, the lift cylinder of shear tester 20
Drive shearing test mechanism 10 to decline, shearing test head is just stuck on tested butt-welding fitting.Now shearing test mechanism 10
Drive cylinder pulls the first Anchor plate kit and the second Anchor plate kit to drive the first work by connected cylinder contiguous block
Dynamic plate 2-5 and the second portable plate 2-6 is parallel opposed longer sides motion, i.e. the first portable plate 2-5 and the second portable plate 2-6 simultaneously along guiding
Axle is mobile towards centre；Now, link assembly 2-14 provides cooperation to complete this motion, its first arm rotates counterclockwise downwards,
Second arm is rotated counterclockwise upwards, drives the first portable plate 2-5 and the second portable plate 2-6 with the rotating shaft at mounting seat 3-1
On the basis of do parallel opposed longer sides motion (while advance to centre or retreat to both sides) simultaneously；And then drive the first portion 2- of shearing test
171 clamp butt-welding fitting with first two 2-172 of shearing test does " shearing " action；The driving force of final drive cylinder is all acted on
On tested butt-welding fitting.During being somebody's turn to do, because pressure sensor is arranged on the second portable plate, pressure sensor is by the second portable plate
Drive and the second Anchor plate kit compress, pressure sensor has also assisted in the conduction of driving force, what drive cylinder was applied
Driving force is to be delivered on pressure sensor and accurately measured, the maximum reading on the pressure display unit connected with pressure sensor
Number is the pressure suffered by tested butt-welding fitting.
In the present embodiment, " the measured value of sensing display show value=sensor=driving force value=actual shearing power
Value ", technical staff can be arranged on shearing force in one true scope according to the technological requirements of different batteries before test,
And because each shearing force is visible, it is to avoid air pressure fluctuation influence shearing force.
Link assembly of the present utility model is the important composition part of shearing test mechanism, and shearing test mechanism and shearing are surveyed
Test-run a machine is used to detect through-wall welding quality by the way of parallel shearing in through-wall welding structure lead-acid battery production process, its
It can accurately detect and show actual shear pressure；And can be in the way of adjusting driving air pressure, according to the work of different batteries
Skill requirement sets different shearing forces or shearing force scope in advance, facilitates the regulation operation of technical staff；Welded according to after shearing
The situation of point, defective products can be found in time, so as to ensure the welding quality of battery in the range of technological requirement.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Embodiment please is confined to these explanations.For person of an ordinary skill in the technical field, do not departing from
On the premise of the design of the application, some simple deduction or replace can also be made.
