Description
Technical field
The present invention relates to machine tool field, particularly relate to a kind of can heavy metalwork processing heavy rotating roller frame, the industries such as the energy, Aeronautics and Astronautics, boats and ships, naval vessel propeller, rolling stock, military project, automobile, mechanical engineering can be widely used in.
Background technology
In prior art, along with the development of Machining Technology and the needs of mechanical processing industry, nuclear power generating equipment, hydroelectric facility, large ship, metallurgical equipment, petrochemical equipments etc. are also to maximization future development, the large-sized gantry boring and milling lathe that can carry out the processing of heavy duty metal part arises at the historic moment and is widely used, band large-scale metal part uses large floor boring and milling machine supporting usually heavy panoramic table when boring-mill work supports, but, the heavy panoramic table that can bear hundreds of tons of weight is bulky and heavy, expensive, once be arranged in floor type boring machine foundation ditch, namely its range of work is fixed up, when larger change when exceeding the support scope of panoramic table occurs the draw ratio of part, often need the equipment newly purchasing respective model, not only cause the idleness of equipment, also substantially increase production cost, and when the boring and milling lathe being provided with heavy panoramic table does not use panoramic table, other boring and milling lathe also cannot utilize this panoramic table, there is investment high, the shortcoming that utilization rate of equipment and installations is low.
In order to solve the problem, China Patent No. " 200920142734.8 " discloses a kind of Telescopic supporting roller stand, its publication date is on October 28th, 2009, its technical scheme comprises base and the wishbone for supporting workpiece, wishbone has the symmetrically arranged left skewback of split and right skewback, the inclined-plane of left skewback and right skewback is provided with the support roller for supporting workpiece, base is provided with oil cylinder, fix bottom the external part of oil cylinder and wishbone, this roller frame is also provided with the stopping means determining wishbone lifting height.
But with the prior art that above-mentioned patent document is representative, in actual use, still there is following defect: one, because left skewback and right skewback are oppositely arranged, support roller is arranged in inclined plane, therefore this patent is mainly suitable for supporting tube shape metal piece, and the larger metalwork of specifications and models difference can not be supported, its narrow application range; Two, because support roller is made up of engineering plastics, relative to large-scale, ultra-large type metalwork, its intensity is still lower, can not be used for supporting more than 150 tons heavy duty metal workpiece; Three, this bracket regulates distance between left skewback and right skewback by wire rod thread, have a common boundary so that metalwork is placed on, and in process, usually also need the position regulating metalwork, now because metalwork is pressed on left skewback and right skewback, need to use very large driving force could regulate successfully, not only can cause very large wearing and tearing to screw mandrel and screw thread, reduce its service life, screw mandrel also can be caused time serious to rupture, cause severe safety accident; Four, in process, need repeatedly to be elevated wishbone and open to rub with the hands with grinding machine head, not only large to the wearing and tearing of oil cylinder, the grinding accuracy of metalwork also can be caused to reduce; Five, this roller frame complex structure, with high costs, and the wearing and tearing between each parts are comparatively large, and service life is low.
Summary of the invention
The object of the invention is to solve the problems referred to above existed in heavy metalwork process in prior art, a kind of heavy rotating roller frame is provided, bearing capacity of the present invention is large, security is high, can regulate the position of metalwork in process easily, is convenient to processing, can be arranged on platform flexibly, can quick-detachment after machining, do not take the station of equipment, improve the utilization rate of equipment.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of heavy rotating roller frame, comprise pedestal, reducing motor, support roller and support roller bracing frame, it is characterized in that: described pedestal offers groove, bottom portion of groove is fixedly installed self-locking jack, described self-locking jack is fixedly connected with bottom support roller bracing frame, and described support roller bracing frame is slidably arranged in groove; Described support roller is flexibly connected with support roller bracing frame, and the work support face of support roller is higher than support roller bracing frame, and the power output shaft of described reducing motor is connected with support roller.
