Description

Press for straightening diamond roll shafts Technical Field The utility model relates to the technical field of presses for straightening roll shafts, in particular to a press for straightening diamond roll shafts. Background The press for straightening the roll shaft is a device for straightening the deformed diamond roll shaft. The utility model discloses a straightener for roll shaft production, which comprises a base and a fixing frame, wherein the fixing frame is fixedly arranged at the middle position of the top of the base, and the straightener further comprises a positioning component and a straightening component. The utility model belongs to the technical field of roll shaft production, and particularly relates to a straightener for roll shaft production, which can clamp and fix two ends of roll shafts with different lengths, solves the problem of roll shaft rotation in calibration, ensures straightening force through a hydraulic rod and improves the straightening effect. The device is slightly insufficient in practical application, and only depends on a group of straightening components in use, so that the stability of the device is not high in use, and the device is easy to overcorrect or overcorrect in use and needs to be improved. Disclosure of utility model The present utility model is directed to solving the technical problems set forth in the background art. The technical scheme is that the press for straightening the diamond roll shaft comprises a mounting plate, wherein a support is fixedly arranged on the bottom surface of the mounting plate, a first rotating roll is fixedly arranged on the surface of the mounting plate, a sliding groove is formed in the surface of the mounting plate, a sliding block is connected inside the sliding groove in a sliding mode, a second rotating roll is fixedly arranged on the upper surface of the sliding block, a moving plate is connected on the bottom surface of the moving block in a sliding mode, a first screw rod is connected with the inner threads of the moving plate, and a motor is fixedly arranged at one end of the first screw rod. Preferably, the number of the sliding grooves is five, and the five sliding grooves are distributed at equal intervals. Here, reinforcing is to the full-segment covering adjustment capability of long size roller, and the equidistant overall arrangement of multiple spot position makes pressure distribution even, avoids single-point overload, improves slider moving track stability, prevents skew jamming. Preferably, the number of the first rotating rollers is four, the number of the second rotating rollers is five, the first rotating rollers and the second rotating rollers are distributed at equal intervals, and the first rotating rollers and the second rotating rollers are staggered. Here, four fixed first rotating rollers of group provide the benchmark supporting surface, and five adjustable second rotating rollers of group form intensive pressure point, and staggered arrangement forms continuous gradual alignment route, eliminates straightness accuracy deviation, and equidistant distribution ensures that alignment force transmission is even, avoids stress concentration. Preferably, the middle parts of the first rotating roller and the second rotating roller are arc-shaped surfaces. The arc-shaped outline is naturally attached to the outer circle of the roll shaft, the contact area is increased, the damage to the surface of a workpiece caused by edges and corners is avoided, the roller is particularly suitable for precision diamond roll shafts, the roller is self-adaptive to curved surface contact of roll shafts with different diameters, and the universality is improved. Preferably, the surface of the mounting plate is fixedly provided with a fixing block, the surface of the fixing block is provided with an arc-shaped groove, and two sides of the fixing block are provided with limit grooves. Here, the arc groove provides assistance-localization real-time benchmark, ensures the initial centering of work piece, and limiting groove constraint movable block motion track promotes and adjusts stability. Preferably, the inside sliding connection of spacing groove has the movable block, the upper surface fixed mounting of movable block has No. two lead screws, no. two lead screw threaded connection is in the inside of fixed block, no. two lead screw's top fixed mounting has the carousel. Compared with the prior art, the utility model has the advantages and positive effects that: 1. According to the utility model, the motor is started to drive the first screw rod to rotate so as to drive the movable plate to move, and the movable plate drives the sliding block to slide in the sliding groove, so that the five groups of second rotating rollers compress and straighten the roller shafts, the roller shafts are compressed in the same time and all directions, and uneven stress is prevented when the roller shafts are processed. 2.
