1. Security is the foremost issue during development at supplier side, and operation at customer side: It should be paid great attention on by both sides before put into use;
Importance of Safety Assurance and Related Safety Risk during Operation of Welding Positioner;
Safety Assurance in Wuxi JACK 2 Axis Standard Type Welding Positioner and its Rotary Welding Table;
Safety Assurance in Wuxi JACK 3 Axis L Type Elevating Welding Positioner and its Welding Turning Table;
Safety Assurance in Wuxi JACK 3 ~4 Axis Head and Tail Welding Positioner and its Rotary Welding Table
1. During application of Welding Positioner, especially those with large size and heavy weight Welding Turning Table, for example: L Type Elevating structure models, or Head and Tail double post models, there exist certain degree of safety risk, which should be taken great caution to eliminate ahead of time;
1) Serious working personnel harm;
2) Damage of workpiece and welding equipment, machine tools at running site;
3) Inferior welding quality delivered from Welding Turning Table;
1) Unreliable sudden unexpected stoppage of Rotary Welding Table in operation period;
2) Sudden falling down of Welding Turning Table and workpiece --- This brings the most serious harm to people and environment;
3) Out of synchronization at both ends of workpiece elevation in Head and Tail Welding Positioner.
This series products have the biggest using volume in market. Shown as below: (Fig.1)
1) 0°~ 360° CW and CCW revolve in adjustable welding speed of Welding Turning Table and workpiece;
2) 0°~ 120° CW and CCW tilt in constant velocity of Welding Turning Table;
1) The motors for driving revolve and tilt of Rotary Welding Table and workpieces are all braking type, guaranteeing on its reliable stoppage when necessary;
2) Conductive rod is installed beneath Rotary Welding Table, forming a welding current circuit in the Welding Positioner, and avoiding the issue of electricity leakage: (Fig.2)
3) Calculate and validate on torque and eccentricity distance sketch of Welding Turning Table, for every model of Welding Positioner: (Fig.3)
This is a kind of very important welding positioning equipment, with working actions of:
1) Up and down elevating movement of its Rotary Welding Table and workpiece within vertical stroke;
2) 0°~ 360° infinite CW and CCW revolve in adjustable welding speed of Welding Turning Table;
3) 0°~ 360° rotating in fixed speed of Welding Turning Table, shown as below: (Fig.4)
1) The motor reducers for driving revolve and rotation of Welding Turning Table and workpiece are all braking type, fully guaranteeing on its reliable stoppage when necessary;
2) The elevation of Rotary Welding Table is driven with hydraulic oil cylinders, and guided with double pieces of precise linear guiderail, shown in below Wuxi JACK 2 Ton L Type Elevating Welding Positioner: (Fig.5)
a) Compared with motor drive and leadscrew transmission in L Type models products produced by some other suppliers,
b) Hydraulic oil cylinder drive for Welding Turning Table elevation in Wuxi JACK L Type models products has heavy and strong driving force, as well as reliable working of elevation.
1. Head and Tail Welding Positioner is a kind of complicated and large welding equipment, for fabricating on diversified long length and heavy weight structure members;
1) The 2 sets of upright columns and Rotary Welding Table are connected by means of a horizontal beam: (Fig.6)
2) There is no direct connection between the 2 sets of upright columns (Headstock and tailstock) and Rotary Welding Table in the installed Head and Tail Welding Positioner at customer facility: (Fig.7)
1) Vertical movement of Welding Turning Table and workpiece within its stroke;
2) 0°~ 360° CW and CCW infinite revolve in adjustable welding speed;
3) 0°~ 360° rotating in fixed speed;
a) The motors and reducers for driving Welding Turning Table and workpiece elevation and revolve are all double stage style with self-lock function;
b) The first stage is gear reducer, fully guaranteeing on delivering of heavy torque;
c) The second stage is worm reducer with self-lock function;
d) The elevating servo motors at both sides of Rotary Welding Table and workpiece also have self-lock function;
e) The Rotary Welding Table revolve driving motor is braking type motor;
All of these fully guarantee on reliable braking of both elevation and revolve for Welding Turning Table, in the process of Head and Tail Welding Positioner operation;
The design and model selection on revolve motor reducer/ mechanical transmission components of Wuxi JACK Head and Tail Welding Positioner all have ample safety margin:
a) Calculation is based on standard of 1.5 times safety margin;
b) The core element (Bearing/ Slewing support) has 2 times safety margin;
a) The revolve of welding turning table is realized with slewing support in Wuxi JACK Head and Tail Welding Positioner: (Fig.8)
b) Upon its revolve at target angular position, there are 8 pieces of air cylinders around the full circle of slewing support to lock the slewing support firmly;
a) Wuxi JACK designs row of safety holes at internal surfaces of the Welding Turning Table;
b) Upon Rotary Welding Table elevated to target level, there are safety pins to have double assurance on completely safety of operation: (Fig.9)
c) These safety pins will be plugged into the safety holes, to avoid the risk of accidental dropping down of Rotary Welding Table and workpiece;
d) The plug-in and pull-out of safety pins is implemented with manual job.
1. The safety measures listed in this short blog are just examples for your reference;
2. As a kind of special design Welding Positioner, more safety measures are put into practice in every business case of Wuxi JACK L Type Elevating Welding Positioner, together with Head and Tail Welding Positioner;
