Heavy rotary supporting roller frame

Abstract

The invention discloses a heavy rotary supporting roller frame. The heavy rotary supporting roller frame comprises a seat body, a speed-reducing motor, a supporting roller and a supporting roller support frame, wherein a groove is formed in the seat body; a self-locking jack is fixedly arranged at the bottom of the groove; the self-locking jack is fixedly connected with the bottom of the supporting roller support frame; the supporting roller support frame is arranged in the groove in a sliding way; the supporting roller is movably connected with the supporting roller support frame; the working supporting surface of the supporting roller is higher than the supporting roller supporting frame; and the power output shaft of the speed-reducing motor is connected with the supporting roller. By using the heavy rotary supporting roller frame, the bearing capacity is high; the safety is high; the position of a metal piece can be adjusted conveniently in a machining process, so that the machining is facilitated; the heavy rotary supporting roller frame can be arranged on a platform flexibly and can be detached quickly after the machining is finished; the working position of equipment is not occupied; and the utilization rate of the equipment is improved.

Description

technical field [0001] The present invention relates to the field of machine tools, in particular to a heavy-duty rotating roller frame capable of supporting the processing of heavy metal parts, which can be widely used in energy, aviation, aerospace, ships, ship propellers, locomotives, military industry, automobiles, mechanical engineering, etc. industry. Background technique [0002] In the existing technology, with the development of machining technology and the needs of the machining industry, nuclear power equipment, hydropower equipment, large ships, metallurgical equipment, petrochemical equipment, etc. are also developing in the direction of large-scale, large-scale gantry that can process heavy metal parts Boring and milling machines emerged as the times require and are widely used. Large-scale metal parts are usually supported by heavy-duty rotary tables that are matched with large-scale floor boring and milling machines. However, heavy-duty rotary tables that can...

Problems solved by technology

[0004] However, the existing technology represented by the above-mentioned patent documents still has the following defects in actual use: 1. Since the left inclined block and the right inclined block are relatively arranged, the supporting roller is arranged on the inclined surface, so this patent mainly It is suitable for supporting cylindrical metal parts, and it cannot support metal parts with large differences in specifications and models. Its strength is still low, and it cannot be used to support more than 150 tons of heavy metal workpieces; 3. The bracket adjusts the distance between the left inclined block and the right inclined block through the screw thread, so that the metal parts are placed on the bridge, and In the process of processing, it is often necessary to adjust the position of the metal parts. At this time, since the metal parts are pressed on the left and right inclined blocks, a large driving force is required to adjust successfully, which will not only cause great damage to the screw rod and thread Large wear and tear will reduce its service life. In serious cases, it will cause the screw rod to break and cause serious safety accidents; 4. During the processing process, it is necessary to repeatedly lift the V-shaped frame so that it can be rubbed away with the grinding head, which will not only cause great wear and tear on the oil cylinder. , will also lead to a reduction in the grinding accuracy of the metal parts; 5. The structure of the supporting wheel frame is complex, the cost is high, the wear between the parts is large, and the service life is low
