Welding Positioner adopts seat type structure, which is mainly composed of frame, rotary mechanism, hydraulic turnover mechanism, conductive device, electrical control system (provided by users) and other parts. Rotary table adopts AC frequency conversion stepless speed regulation, uniform speed, no crawling, ensure to meet the requirements of welding parts for rotary speed.
The frame is composed of section steel and steel plate assembly welding, reasonable structure design, with good bending and torsion resistance, is an important bearing parts. In order to ensure the structural strength, we combine the frame and the base as a whole, and weld a lot of stiffeners in the inner cavity according to the stress condition. The extension length of the base legs exceeds the maximum center of gravity distance of the workpiece. The center of gravity of the workpiece is controlled within the specified center of gravity distance, and the device will not overturn. The center of gravity of the workpiece does not exceed the support leg, and the positioner can be directly placed on the hardened flat ground of the workshop for use, so it is easy to move. There is a set of bolt holes on the bottom plate of the support leg. If the center of gravity of the workpiece exceeds the support leg, the equipment can be fixed on the workshop floor with standard expansion bolts for safe use. When the center of gravity of the workpiece is too high, in order to ensure the safety of use, the equipment foundation can be constructed according to the foundation drawing according to the needs of users.
Rotary mechanism is mainly composed of rotary table, rotary bearing, transmission mechanism and so on. The whole rotary mechanism is installed on the beam turnover frame of the box structure, which supports and bears the workpiece by the turnover frame, and transfers the weight of the workpiece to the bracket on both sides through the turnover frame, which can bear the larger impact load and twisting force. Box structure has great torsion resistance, can effectively carry heavy load. Box structure after welding processing, according to the stress in the appropriate position of the arrangement of a large number of reinforcement.
Table top is circular structure, the concentric circles with equal spacing are processed above, and the radial T-groove (t-bolt special) is processed on the table. Even in the workpiece, it is easy to install all kinds of positioning and clamping tools.
The worktable is fixed on the special heavy slewing bearing of the lifting equipment to ensure smooth slewing under the rated load. The slewing bearing adopts “single volleyball slewing bearing” with high precision toothed rotary plate, which can bear axial force, radial force and overturning moment at the same time. It has large bearing capacity, high slewing precision, reasonable structure, good rigidity, light weight and long service life. The slewing bearing is fully sealed, the grease is not easy to leak, the slewing bearing is equipped with a metal casing to prevent dust from entering and damaging the slewing bearing, and it can adapt to the harsh welding environment. Special metal oiling hose is equipped on the slewing support for convenient and fast oiling.
Rotary driving principle of worktable: brake motor – double cycloid reducer (by-1000Y using worm gear and worm reducer)- pinion – slewing bearing – rotary worktable When the equipment works under rated load, through the braking function of the brake motor, ensure that the worktable can be locked in any position when stopping rotary Drive motor adopts frequency conversion stepless speed regulation, constant torque output in a wide speed regulation range
Turnover working principle: hydraulic cylinder – turnover support – turnover frame – workpiece. Driven by hydraulic pressure, it has the characteristics of large bearing capacity and strong impact resistance to ensure that the reducer works safely and smoothly in the process of turning over. At the same time, the design of two-way hydraulic lock, to ensure the safety of flipping.
The material of driving pinion is 40Cr, after quenching and tempering tooth surface, with soft inside and hard outside, to achieve high strength.
A conductive device is installed below the worktable, so as to form a good conductive circuit for welding ground wire, so as to avoid overelectricity of the slewing bearing and affect its service life. The conductive device is a tube structure, which is composed of a guiding torch and a conductive rod. The conductive device is fixed near the center of rotation, and the copper rod is in contact with the workbench to form a conductive circuit for welding ground wire. Insulation treatment is adopted between the conductive device and the beam to prevent the component damage caused by electricity passing through the bearing. The conductivity of the conductive device is 1000A.
