1) The LBS20 model loading tonnage of 2 Ton Weld Turning Table is medium model of this product group;
2) This model has the similar working principle, mechanical structure, degree of freedom, and control logic as the lighter duty of LBS10 model (1 Ton Weld Turning Table loading capacity), LBS12 model (1.2 Ton) and heavier duty of LBS30 3 Ton specification;
3) Depending on size of workpieces to be secured into the Weld Turning Table, the LBS20 model 1.2 Ton loading tonnage has vertical travel stroke of 1000~1200mm.
Below descriptions are applicable for full range of the Weld Turning Table loading capacity from 1 Ton to 3 Ton and above (LBS10 ~ LBS30 and larger models) in the LBS model L type Elevating type Welding Positioner:
1) Guiderails for Guiding Elevation of Weld Turning Table in the Elevating type Welding Positioner: (Fig.1)
a) As can be seen from the above picture, there are 4 pieces of ball bearing linear guideways (the best of its kind) in one set of LBS L type Elevating and Revolving Welding Positioner, fit at the 4 edges of internal surface of mechanical main frame, or called the left and right 2 pieces of columns (marked in yellow color square in the picture);
b) This is similar to the product H Beam Assembly Welding Straightening Integral machine. It is for the purpose of guiding the smooth and stable movement of L arm and Weld Turning Table along vertical direction;
a) Hydraulic cylinder is fit at its beneath to give power on L arm and Weld Turning Table up and down movement;
b) Hydraulic pump station is put alongside the equipment frame of the LBS20 model L type welding positioner;
c) Due to the larger size of pump station for 2 Ton loading capacity LBS20 model, it can not be put inside the cavity of machine body as in the case of LBS10 model: (Fig.2)
3) Mounting Carriage for the L Arm and Weld Turning Table: (Fig.3)
a) In LBS series L type Lifting and Revolving Welding Positioner, with the increasement of loading tonnage from 2 ton, the mounting carriage for holding the L arm is also strengthened, marked in yellow color square in the above picture;
b) There are several pieces of stiffeners welded onto the mounting carriage;
a) Besides, due to the heavier workpiece applied in the LBS20 model and heavier loading capacity in the L type Welding Positioner, safety is the foremost considered factor: (Fig.4)
b) As can be seen from the above picture, eye catching warning signs of bright yellow stripes, and alarm lights are applied on the motion units L Arm and Weld Turning Table. Please check the above picture, marked in yellow color square in the picture;
a) From the above picture we can observe, that black color dust proof cover is applied for the transmission mechanism of motioning unit L Arm and Weld Turning Table, in the LBS models welding equipment, marked in yellow color square in the picture: (Fig.5)
b) This gives contamination control protection on this Elevating type Welding Positioner working in rigorous welding environment.
