Description

Heavy-duty swivel roller frame

technical field

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

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 withstand hundreds of tons are bulky and heavy, and the price Expensive. Once installed in the foundation pit of the floor boring machine, its processing range is fixed. When the length-to-diameter ratio of the part changes greatly and exceeds the support range of the rotary table, it is often necessary to purchase new equipment of the corresponding type, which not only causes the equipment to be idle. It also greatly increases the production cost; and when the boring and milling machine tool equipped with the heavy-duty rotary table does not use the rotary table, other boring and milling machine tools cannot use the rotary table, which has the disadvantages of high investment and low equipment utilization rate.

In order to solve the above problems, Chinese Patent No. "200920142734.8" discloses a telescopic roller support, and its publication date is October 28, 2009. Its technical solution includes a base and a V-shaped frame for supporting workpieces. There are left inclined block and right inclined block which are symmetrically arranged in separate parts. Supporting rollers for supporting the workpiece are arranged on the slopes of the left inclined block and the right inclined block. There is an oil cylinder on the base, and the protruding end of the oil cylinder is connected with the bottom of the V-shaped frame. Fixed, the supporting wheel frame is also provided with a limit device to determine the rising height of the V-shaped frame.

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. , also can cause the grinding precision of metal parts to reduce; Five, this supporting roller frame is complex in structure, and cost is high, and the wear and tear among each parts is bigger, and service life is low.
