2)  Elevating stroke is 2000mm, with lifting speed adjustable in the range of 1000 ~ 4000 mm/min., servo motor drive and management;

3)  0° ~ 360° revolving of Rotary Welding Table, adjustable rotating linear speed of 0.1 ~ 1 rpm. This is also the welding working velocity;

5.  Applied Industry: Such Double Column Head and Tail Welding Positioner is indispensable Welding Positioning Equipment, being used in industries of Vehicle/ Construction Machinery/ Engineering Machinery/ Automobile.

B. Critical Precondition and Performance Index of Lifting and Rotating Head and Tail Welding Turning Table:

To attain safe/ reliable/ precise/ satisfactory performance of the equipment, 2 key technical performance should be acquired in this Double Column Welding Positioner:

1. Removing Safety Hidden Trouble of Welding Turning Table Sudden Falling Down in Operation:

Why so Important?

1) The top height level of Welding Turning Table and workpieces is 2000mm;

2)  The max. weight of chassis that can be held, revolved and lifted is 10 Ton;

3)  So, if working motions of Rotary Welding Table is not dependable: Disengaged from upright columns, and suddenly dropped down out of expectation, there will be great harm to working staff on site, and running utilities of the Double Column Welding Positioner environment;

2. Perfect In Phase Elevation of Workpiece Both Ends along Upright Columns in Head and Tail Welding Positioner:

1) Way of Workpieces Chassis Fixation: In this welding machinery, both ends of large workpiece chassis are secured respectively;

2)  Each piece of Rotary Welding Table is installed into upright column respectively;

3) So, during elevation of the 2 pieces of Welding Turning Table, it should be maintained into perfect synchronization;

4) Workpiece reliably fixation onto Welding Turning Table: (Fig.2)

C. Safety Assurance of Wuxi JACK Double Column Welding Positioning Equipment:

1) Safety is always the foremost factor to be considered during developing all of Wuxi JACK products, including Double Column Welding Positioner;

2) Series of measures are taken during the designing process:

1.   Braking Type Motor Reducers are adopted in elevation driving mechanism of Rotary Welding Table;

2.  Slew Ring in Rotary Welding Table:

1) Great Importance: Slew ring matters most in operation of the Head and Tail Double Column Welding Positioner: It directly determines smooth revolve of workpiece, as well as sure fire fixation of the workpiece;

2) Safety Holes: In slew rings of Rotary Welding Table, there are row of safety holes drilled into the complete external periphery circle of slew rings;

3) Role of Slew Support in Head and Tail Welding Positioner:

a)  During welding and idle running period, in case of contingency happens,

b)  Safety pins on assembling mechanism will be ejected out with no time delay,

c) And being plugged into safety hole, preventing the Welding Turning Table and workpiece from falling down:

d)  Slew rings and its safety holes to be fit into Welding Turning Table: (Fig.3)

4) Slew support to be installed in Rotary Welding Table: (Fig.4)

5) Related Equipment: In this respect, we can see that safety assurance mechanism in elevating style Head and Tail Welding Positioner, is similar to another widely applied equipment: Welding Column and Boom;

3. Emergency STOP buttons are installed at numerous places in the entire working zone of Double Column Head and Tail Welding Positioner, for the purpose of easy reach by operators within arms length.

D. Technical Performance of Double Column Head and Tail Welding Positioning Equipment:

1. Structure of Head and Tail Double Column Welding Positioner:

1) Main Units: One set of this large size welding machinery is composed of two sets of upright columns, 2 pieces of Welding Turning Table, and electric system;

2) So, it is also called Double Column Welding Positioner;

3) Upright Column Fixation Way: The 2 sets of upright columns can be either fixed into workshop floor, which is used for conditions of fabricating on fixed max. length workpiece;

4) Column Moving Type: Or, one set or both sets of the columns can move along ground rails, so that wide variety of workpiece length can be fit into the equipment:

5) Installation and commissioning site of Wuxi JACK column moving Head and Tail Welding Positioner: (Fig.5)

2. Simultaneously Elevation Management in Double Column Head and Tail Welding Positioner:

1) Drive: Both ends elevation of workpiece chassis along the 2 sets of upright columns are driven with servo motor;

2) Control: Of which, controlled with input pulse command, elevation of workpiece can guarantee fully simultaneous elevation of workpiece at both ends;

3)  This can make sure perfect horizontal level of the workpiece all the while, together with the 2 sets of Rotary Welding Table；

3. Elevation Safety Management in Double Column Welding Positioning Equipment:

1) Braking Type: The 2 sets of Welding Turning Table elevating purpose servo drive motors are all equipped with brakers;

2) Besides, primary brakers are worm gear reducer, with good braking function;

3) In this way, elevation safety of workpiece can be fully guaranteed；

4. Welding Turning Table Elevation Mechanism:

1) Transmission: workpiece elevation is realized by means of chain and sprocket transmission;

2) Guidance Unit: There are heavy duty precise guiderails assembled onto the 2 pieces of upright columns;

3)  Rolling wheels roll along the heavy duty precise linear guiderails, which are assembled onto the upright columns instead of welded structure, guaranteeing stable and reliable elevation of workpiece and Welding Turning Table:

4) Driving, Guiding and Transmission unit for Rotary Welding Table elevation in Wuxi JACK Double Column Head and Tail Welding Positioner: (Fig.6)

5. Workpiece Revolve in Welding Turning Table:

1) Revolve of workpiece is driven with Y series A.C. motor and reducer, and also equipped with braking unit;

2) In this way, when the welding turning table and workpieces chassis is revolved to target angular position, it will be locked automatically.
