Description
Technical Field
The invention relates to a machine tool clamp, in particular to a clamp used in grinding of a bearing box body of a working roll.
Background
As is well known, rolls are generally classified into backup rolls and work rolls. In the finishing train of a hot rolling mill, the backing rolls and work rolls are typically mounted in a stand by being supported in a bearing housing by bearings. After the roller rolls for a period of time, the precision of the roller surface is reduced to influence the rolling quality, and the machine frame needs to be detached and a roller grinder is used for grinding correction. If the bearing box is disassembled and assembled, the hoisting is troublesome, a large amount of auxiliary time is increased, the labor intensity is high, and the defects of complexity, time consumption, low efficiency and high production cost are overcome. The bearing box of the supporting roller is too large in size, and only a method of grinding after the bearing box is detached can be adopted. The bearing box body of the working roll has moderate volume and can be ground by an on-line belt box generally. The bearing box of the working roll generally has a special shape and a larger overall dimension, and if the working roll with the bearing box in a natural state is directly placed on a roll grinder for grinding, the interference phenomenon between the bearing box and a grinding carriage of the grinder can occur in the grinding process, and the bearing box of the working roll generally needs to be turned over for a certain angle. Because the bearing box body of the working roller is a movable structure supported by the bearing, a mechanism for turning the bearing box body is invented in various forms, such as four-connecting-rod type, arc guide rail type, spear type and other turning mechanisms, and the bearing box body can be turned by a specific angle. After the bearing box body overturns a certain angle, the bearing box body is no longer in a dead weight state, and if no other mechanism is matched with the overturning mechanism to restrain the bearing box body, the bearing box body can generate great shaking in the grinding process, so that the higher grinding precision of the working roller can not be ensured. In the market at present, a mechanism for restraining by matching with a turnover mechanism is to additionally arrange a connecting rod supporting mechanism formed by the action of two oil cylinders below a bearing box body to support the box body; however, when the turning radius of the bearing housing of the workpiece is too large, and the size and the center of the machine tool are limited to be high, the turned bearing housing may collide and interfere with the supporting mechanism fixed below the position of the bearing housing.
Under the above-mentioned realistic background, it is necessary to develop a set of mechanism that cooperates with the turnover mechanism to support, avoid various interferences that occur during the turnover process of the bearing box body, and can well support the bearing box body after the bearing box body is turned over in place to restrain the shaking of the bearing box body, so as to meet the requirements of the current automated production.
