LHZ Light Duty Travelable Trolley Column Electric Revolve Welding Manipulator

Quantity:

In this section of light duty travelable column and boom with electric-revolving of column, we will explore characteristic and usage of each main unit of the machine.

 

A draft on formation of a classic traveling column and boom sees below:

Illustration-1A

   1) Welding Head

      - Including torch and wire feeder;

      - Torch and wire feeder are equipped together with welding power source;

      - Different types of welding mode involve corresponding welding head;

      - Besides welding, the machine can perform operation other than welding, such as carbon arc gouging,

        polishing, etc. when fit with corresponding operating unit. We can see the machine is a convenient welding

        column and boom;

   2) Welding Head Manipulating unit

    - Including console of welding power source;

    - Console of wire feeder;

    - Mechanism for adjusting welding torch up and down, left and right, for aiming at welding seam perfectly all

      along;

    - Optional Seam Tracing unit, Video Monitor is also installed at this position;

   3) Column

    - It is “trunk” for a set of welding column & boom, supporting vertical and horizontal movement of boom;

    - It is steel structure member processed with steel plate bending and then welding;

   4) Boom Elevating Motor

    - Generally fit at top of the column;

    - For safety reason, it is braking type motor transmitted with worm gear reducer;

  5) Trolley or Base

    - In traveling type weld manipulator, it is in the form of trolley;

    - In stationary type column & boom, it is in the form of cross base for light duty and box-type bed for medium

      duty and heavy duty;

    - For traveling type, inside the trolley is installed with motor reducer, with 4 wheels fit at its bottom, and welding

      power source put on the trolley;

   6) Slewing Support

    -  This round-shape finely machined gear is outsourced part, fit inside the square-shape bed, for leading 

      revolving of column. See below picture:

 Slew Support

   7) Welding Power Source

     - Location of the welding power source in the draft is not proper. As mentioned in item 5, for a set of traveling

        type high efficiency welding manipulator, usually it is put on the trolley. For fixed-base type, it is put on the 

        floor;

    8) Cross Slide (or, Saddle)

     - This is the joint of automatic welding column and boom;

     - It guides both vertical and horizontal movement of boom, this is the name “cross slide” derives;

     - Due to its shape, it is also called saddle;

     - This unit of Light duty, medium duty and heavy duty convenient welding manipulator has slightly different

       appearance. But working principle all the same;

    9) Boom

     - It is “arm” for a set of efficient column and boom;

     - Operating unit (welding) is fit at its front end;

     - Same as column, it is steel structure member processed with steel plate bending and then welding
