Embodiment 1

[0025] By adjusting the action of the oil cylinder 4, the position of the guide rod 3 is adjusted longitudinally, so as to drive the linkage mechanism 2 along the guide rod 3 and the synchronization shaft 6 to adjust the axial displacement synchronously. Since the compression head 5 is arranged under the linkage mechanism 2, So as to realize the synchronous adjustment of the center distance t.

Embodiment 2

[0027] The compression cylinder 8 is pressed downwards, thereby compressing the movable beams 7 on both sides, and the compression head 5 is compressed downward as a whole through the synchronization shaft 6. This mechanism has one set of upper and lower mechanism, and the two sets of mechanisms act at the same time. Through position control, the clamping mechanism 8 can flexibly hold the straightening roller flange in any position up and down, thereby minimizing the length. Time to replace the straightening roller. The position control of the compression cylinder 8 is easily realized in the field of hydraulic control.

[0028] The invention is mainly used to adjust the flange clamping mechanism of the variable roll distance straightening machine. When the center distance of the straightening machine changes, it can effectively change the center distance of the clamping mechanism and clamp the flange of the straightening roll so as to Quick roll change and precise positioning in...

Abstract

A novel variable-roller-pitch connection shaft adjusting clamping mechanism comprises mechanism bodies in vertical symmetry. Straightening rollers are arranged between the mechanism bodies. Each mechanism body comprises a horizontal base, a guide rod and a synchronous shaft, wherein an adjustment oil cylinder is arranged at the center of the space between the base and the guide rod, compression oil cylinders are arranged at the two ends of the space between the base and the guide rod, a connection mechanism is arranged between the guide rod and the synchronous shaft, the connection rod mechanism is driven by the adjustment oil cylinders to conduct axial movement along the guide rod and the synchronous shaft for synchronous adjustment, the compression oil cylinders are arranged on moving beams, the moving beams are located at the ends between the guide rod and the synchronous shaft, the straightening rollers are provided with straightening roller spline flanges, and the synchronous shaft is provided with compression heads used for tightly holding the straightening roller spline flanges. The novel variable-roller-pitch connection shaft adjusting clamping mechanism is flexible in adjustment and greatly saves centering time and effort during roller replacement of a straightening machine.

Description

Technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a novel variable roll pitch connecting shaft adjusting and clamping mechanism. Background technique [0002] In the existing variable-roller pitch plate straightening machine, when the straightening rolls with different center distances are replaced, since the couplings of the straightening machine mostly use cross-head universal joint couplings, they need to be re-centered manually. A lot of time and energy was wasted. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a new type of variable roll pitch connecting shaft adjusting and clamping mechanism, which is used to adjust the clamping mechanism of the straightening roll of the variable roll pitch sheet straightening machine. When the center distance of the machine changes, the center distance of the clamping m...
