Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cylinder body polishing, and particularly relates to a variable-diameter inner wall polishing device. Background Technique
[0002] Hydraulic cylinder is a kind of pressure finishing machining, which utilizes the cold plasticity characteristics of metal at normal temperature state. By applying a certain pressure on the surface of the workpiece with a rolling tool, the surface metal of the workpiece undergoes plastic flow and fills into the original residual low concave valleys, so as to reduce the surface roughness value of the workpiece. Due to the plastic deformation of the surface metal being rolled, the surface structure is cold hardened and the grains become finer, forming a dense fibrous shape and a residual stress layer, with the hardness and strength increased, thus improving the wear resistance, corrosion resistance and fit of the workpiece surface. During the manufacturing process of the cylinder barrel of the hydraulic cylinder, it is necessary to process the inner hole for degreasing, polishing, rust removal, etc. The traditional method uses internal hole honing or simple tooling for polishing. The honing method is greatly restricted by equipment, with too long auxiliary time and low efficiency; the simple tooling polishing method is too simple and the effect is difficult to guarantee. Therefore, a new type of cylinder barrel inner wall polishing device is needed. Content of the Utility Model

A bearing assembly is arranged on the upper surface of the substrate, and a polishing assembly corresponding to the bearing assembly is arranged on the upper surface of the substrate. The polishing assembly is connected with a variable-diameter assembly; the polishing assembly includes a guide groove opened on the upper surface of the substrate. A moving seat is slidably connected inside the guide groove. A vertical plate is fixedly arranged on the right side wall of the moving seat. A first motor is fixedly arranged at the upper end of the moving seat. The output shaft of the first motor is connected with a rotating shaft, and a polishing part is fixedly arranged at the outer end of the rotating shaft. When in use, place the cylinder barrel above the bearing assembly, drive the polishing assembly to move towards the inside of the cylinder barrel through the variable-diameter assembly, and polish the circumferential inner wall of the cylinder barrel by the rotation of the polishing part of the polishing assembly. During the polishing process of the circumferential inner wall of the cylinder barrel by the polishing part, use the hydraulic telescopic column of the variable-diameter assembly to shorten or elongate the diameter body, so as to realize the real-time change of the polishing position during the polishing process of the cylinder barrel. During the polishing process of the cylinder barrel inner wall, the labor intensity of the operating personnel is reduced and the work efficiency is greatly improved.
[0005] Further, the bearing assembly includes a driving assembly fixedly arranged on the upper surface of the substrate near the front side wall, and a driven assembly arranged corresponding to the driving assembly. The driving assembly includes a first vertical plate and a second vertical plate fixedly arranged on the upper surface of the substrate.

[0009] The beneficial effects of the present utility model: The inner peripheral wall of the cylinder barrel is polished by the rotation of the polishing part of the polishing assembly. During the polishing process of the inner peripheral wall of the cylinder barrel by the polishing part, the diameter of the hydraulic telescopic column of the diameter-changing assembly is shortened or elongated to realize the real-time change of the polishing position during the polishing process of the cylinder barrel. During use, the cylinder barrel is placed above the front cross shaft and the rear cross shaft, and the cylinder barrel is supported by the front cross shaft and the rear cross shaft.
