Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
A kind of lever floating puppet weldering arm for double appearance solder joints as shown in Figure of description comprising soldering turret pressure
Arm 7, the two sides of soldering turret pressure arm 7 are connected with soldering turret swing arm 8, moving electrode 9 are connected on soldering turret swing arm 8;The setting of 7 end of soldering turret pressure arm
Have multiple mounting grooves, lever shaft 12 be provided in each mounting groove, be provided with above mounting groove removably with soldering turret pressure arm 7
The briquetting 14 of connection, one end of briquetting 14 towards mounting groove are provided with arc pressure head 14.1, the central axes of arc pressure head 14.1 with
The central axes antarafacial of lever shaft 12 is vertical, and the distance of the groove bottom of the end of arc pressure head 14.1 to the mounting groove is greater than lever
The diameter of axis 12, the both ends of lever shaft 12 are connected separately with the connection of soldering turret swing arm 8.Adjusting is provided between briquetting 14 and mounting groove
Gasket 15.The lower end surface of briquetting 14 to mounting groove groove bottom distance+briquetting 14 thickness G T.GT.GT lever shaft 12 diameter.Soldering turret
Y-direction adjusting screw rod 13, the central axis of Y-direction adjusting screw rod 13 and the centerline axis parallel of lever shaft 12 are provided on swing arm 8.Peace
The width of tankage is corresponding with the diameter of lever shaft 12.Lever shaft 12 is two.Briquetting 14 is π shape, the shape and pressure of mounting groove
The shape of block 14 is corresponding.Soldering turret swing arm 8 is symmetrically disposed on the two sides of soldering turret pressure arm 7.
The invention also discloses following welding tong structures: designing two grooves in the end of the pressure arm 7 of puppet's soldering turret, passes through two
Root cylinder lever shaft 12, and briquetting 14 (having arc pressure head as fulcrum) is used to push down.Between briquetting 14 and the groove of pressure arm 7
Using being bolted, gap both can be adjusted by adjusting gasket 15, make between lever shaft 12 and briquetting 14 that there are 1mm or so
Floating surplus.In this way, which lever shaft 12, which using the contact surface of briquetting 14 as fulcrum, just forms one, is similar to seesaw
, can be along the lever mechanism for being parallel to electrode Impact direction and agitating.The amount of floating of the mechanism can be used Y-direction and adjust 13 He of bolt
Adjusting gasket 15 adjusts, to be applicable in different operating conditions.
Two moving electrodes 9 are rigidly secured to the both ends of lever shaft 12 by nut respectively.When moving electrode 9 is pressed on plate
When, plate bring counteractive support power can be transmitted on lever shaft, because lever shaft is designed as relocatable form, reaction
Power can make lever shaft that small angle tilt occur for fulcrum with briquetting 14, and form branch under the effect of the pressure of briquetting 14
Support.So, the pressure of cylinder passes through the conduction of pressure arm, lever shaft, and stable shares to two moving electrodes.Even if two
Electrode cap generates unequal abrasion, and two electrode caps, which remain on, can closely be compacted plate, and reaches expected welding pressure
Power (see Fig. 4).
The operation logic of puppet's soldering turret are as follows: under the active force of cylinder 5, soldering turret pressure arm 7 overturns and moving electrode arm 8 is driven to press
Tight plate.When cylinder stroke reaches maximum, sensor 6 detects mechanism in place, and the power on pressure arm passes through machinery at this time
In structural transmission to moving electrode 9, and under the action of the reverse side support force of stationary electrode 10 is common, continue to export to plate maximum
Pressure.Later, external soldering turret carries out spot welding on copper bar 1 and connects operation, and by the transmitting of attached cable 2, welding current is transferred to
Moving electrode 9 and stationary electrode 10.Interelectrode electric current generates resistance heat by plate, forms weld nugget, completes welding process.
In general, stationary electrode 10 is designed to the appearance weldering obtained in this way with the matched welding copper sheet in accessory appearance face type face
The smooth no impression of point, it is best in quality.
But can puppet's soldering turret mechanism export the welding pressure of setting, be the key that ensure appearance solder joint quality.For up to
To the stable output pressure for meeting welding condition, it should be noted that following factor:
1. cylinder model selects:
When selecting 5 model of cylinder, need to carry out the calculating of cylinder output pressure, its calculation formula is:
The integrated number of welds of output pressure=cylinder bore diameter floor space × system pressure ÷ puppet's soldering turret
Both: F=[π × (D/2)2×P]/N
Such as: puppet's soldering turret welds two solder joints simultaneously, if choosing the cylinder of cylinder diameter φ 100mm, single solder joint is obtained
The output pressure obtained are as follows:
[3.14×(10cm/2)2× 6bar]/2=235.5 kilograms=235.5daN
In addition, the selection of air cylinder guide rod length is also required to meet range demands necessary to mechanism is overturn, if cylinder is led
Pole length is too short, and mechanism does not overturn the extreme limit of travel for just having had arrived at guide rod in place also, then equally will appear insufficient pressure
Situation.
2. the structural strength that stationary electrode supports (part 11):
The effect of stationary electrode support 11 is that electrostatic polar cap is firmly installed in chuck body, and effect is similar to common
The electrostatic polar arm of soldering turret.Because stationary electrode needs to bear biggish welding pressure, therefore its support has to be designed as having enough
Rigid, otherwise, positional shift can occur in pressure-bearing for stationary electrode, and pressure is caused to be consumed.
3. electrode cap is worn:
In view of electrode cap is easy consumable accessories, can unavoidably be worn away after frequent welding.When puppet's soldering turret is integrated
Two electrode cap abrasion loss differences when, if using rigid connection between moving electrode and cylinder pressure arm, electrode cap and plate
Contact surface does not have any floating surplus, then will lead to formed between abrasion loss more that electrode cap and plate it is small between
Gap, seriously affects soldering turret output pressure at the case where causing solder joint virtual pressure, and appearance solder joint is made even fried rifle of shrinkage cavity, pit etc. occur
Defect.And the present invention makes electrode cap can produce 2mm then by the way that puppet's weldering soldering turret is designed as a kind of lever-type relocation mechanism
Amount of floating, even if electrode cap wear, closely plate can also be compacted, avoid the generation of above situation.
It should be understood that the above is only the specific embodiments of the utility model, but the protection scope of the utility model
It is not limited thereto, anyone skilled in the art can be thought easily in the technical scope disclosed by the utility model
The change or replacement arrived, should be covered within the scope of the utility model.
