Spline shaft structure applicable to end face polishing operation of work piece, and polishing equipment

Abstract

The invention discloses a spline shaft structure applicable to end face polishing operation of a work piece, and polishing equipment. The spline shaft comprises a ventilating shaft; a to-be-polished work piece fixedly sleeves the outer end part of the ventilating shaft; a steel ball idler wheel for driving the ventilating shaft and the to-be-polished work piece to do forward and backward telescopic motion is arranged at the inner end part of the ventilating shaft; the middle part of the ventilating shaft is also provided with a friction wheel for driving the ventilating shaft to rotate; moreover, the ventilating shaft is also provided with a rotary joint for inhaling compressed air; an air chamber communicating with the rotary joint is arranged inside the ventilating shaft; the air chamber extends to a position, for mounting the to-be-polished work piece, of the ventilating shaft, and a ventilating hole for making the air chamber communicate with the inner chamber of the to-be-polished work piece is arranged at the position. The spline shaft structure disclosed by the invention is capable of preventing the problem of poor parallelism caused by manual operation and the problem of low efficiency, and has the advantages of improving the production efficiency and also improving the grinding quality.

Description

technical field [0001] The invention relates to a spline shaft structure suitable for polishing the end surface of a workpiece, and polishing equipment adopting the spline shaft structure. Background technique [0002] In the field of mechanical processing, the roughness of the end surface of the workpiece to be processed is relatively high. After the rough and fine turning of the turning tool on the lathe, the progress still cannot meet the requirements. At this time, it is necessary to use a grinder to grind the end surface of the workpiece to be processed. However, for workpieces, traces of injection molding processing are usually left on the surface, especially the end face, such as parting lines, etc. In this case, grinding machines cannot be used for machining and grinding; the traditional method of removing parting lines on the end face usually uses It can be realized by manual edge trimming or manual grinding, but the manual edge trimming method has the problems of u...
