Specification: The LBS10 model L type Welding Positioner with revolving and elevation function has loading capacity of up to 1 Ton, and Welding Turning Table vertical stroke of 800mm, which is often used for welding small structure members in Engineering Machinery and or similar application.
Wuxi JACK L type Welding Positioner in operation at customer site: (Fig.1)
1) One of the critical points in design and manufacture this L type Revolving and Elevating Welding Positioner, is its drive and transmission mechanism for L arm vertical movement, especially for those welding equipment with Welding Turning Table loading tonnage less than 2 Ton;
a) 0°~360° Rotation of L arm in vertical plane: Driven with mechanical motor reducer and transmitted with leadscrew;
b) 0°~360° revolve of the Welding Turning Table at the front extension of L arm: Also driven with mechanical motor reducer and transmitted with leadscrew;
i. For loading capacity of the Welding Turning Table higher than 2 Ton (Including 2 Ton), or LBS20 and above, it is hydraulic drive;
ii. For loading capacity of the Welding Turning Table below 2 Ton, there are 2 options for driving vertical drive of the L arm: Mechanical motor reducer leading leadscrew, or driven hydraulic system.
Of the above mentioned 2 options for L arm elevation in this Elevating and Revolving Welding Positioner, we prefer and adopt with hydraulic drive:
a) Such selection on hydraulic drive is considered out of safety purpose:
b) During working period, Suppose the L arm ascends to its top position, and what if defect happens with its driving and transmission system…
c) If the elevation of L arm is driven with motor reducer and transmitted by means of leadscrew, there exist potential risk of L arm falling down: The engagement between the leadscrew and nut may become slipped due to worn condition of fitting nut. And in such case, a chain of malfunction and safety issues may occur;
a) On the other hand, in hydraulic driving system of this welding equipment, it is fit with an explosion proof valve;
b) Such way of drive is a fool proof solution for up and down movement of the L arm, and hence eliminate risk of L arm dropping down when it is at its top position of the L type Welding Positioner;
3) In this respect, this LBS10 1 Ton loading capacity of Welding Turning Table can be viewed as either an electric motor drive L type Welding Positioner, considering L arm rotation and Welding Turning Table revolve, or a set of Hydraulic Welding Positioner, in view of its L arm upright direction movement drive.
1) Checking from below picture, for this Welding Turning Table 1 Ton loading tonnage of the welding equipment (Or electric motor drive), its hydraulic pump has compact size: (Fig.2)
2) We put it inside bottom cavity of the L type Welding Positioner mechanical column. With an integrated button on operating pendant of this welding equipment, the hydraulic system can be manipulated;
3) For more details on structure and performance of the hydraulic drive welding equipment, we will have more introduction in the ensuing product sections of 1.2 Ton, 2 Ton, and 3 Ton;
