Disclosure of Invention
Aiming at the problem of larger jumping quantity of a slender shaft machined on a common lathe, the design provides a method for improving the machining quality of the slender shaft by adopting an auxiliary tool, a self-made support is fixed on a lathe tool rest, a free auxiliary supporting roller (hereinafter referred to as an auxiliary wheel) is connected on the support through a self-made bolt with a clearance groove, during machining, the distance between the auxiliary wheel and the surface of a workpiece to be machined is required to be roughly adjusted, so that the auxiliary wheel is attached to the non-machined surface of the slender shaft, the auxiliary wheel can freely move after being matched with the self-made bolt, namely, the auxiliary wheel can play a limiting role and has abundant moving space and non-fixed matching, a floating structure is formed, the auxiliary wheel can automatically align along with the rotation of the workpiece, meanwhile, the roller on the auxiliary wheel can simultaneously rotate along with the rotation of the slender shaft, the effect of 'soft assistance' is really played, and cooling liquid is sprayed from an oil, and (5) auxiliary processing. Therefore, the surface quality of the part can be maximally protected on the premise of reducing the part bounce.
Technical scheme
The auxiliary machining device for the slender shaft of the aviation product comprises a self-made bolt, a bracket and a supporting roller; the self-control bolt is equipped with screw thread A and screw thread B, and screw thread A and leg joint, screw thread B and the inner chamber outside screw hole phase-match on the supporting roller, are equipped with one section optical axis in the middle of two sections screw thread A and screw thread B, and the optical axis diameter is less than screw thread B diameter. One end of the support roller is provided with a threaded hole matched with the thread B of the self-made bolt, the bottom of the threaded hole is provided with an inner cavity, and the diameter of the inner cavity is larger than that of the thread B of the self-made bolt; the other end is provided with two rollers which are symmetrically distributed.
Technical effects
When the slender shaft with the length-diameter ratio of 20-35 is machined, the invention obviously reduces the jumping amount of the shaft in rotation and improves the product quality, basically has no damage to the surface of the shaft and has good machining effect. And the tool is simple and easy to use, is convenient to adjust, improves the processing efficiency, and has excellent performance in the working of slender shaft processing, shaft knurling and the like.

Detailed Description
The auxiliary support roller is used in the processing process of the slender shaft with the maximum length-diameter ratio of 24, the using effect is excellent, the free auxiliary support roller can reach an ideal state, the auxiliary support roller is flexibly attached along with the rotation of a workpiece, the processing quality of a product is guaranteed, and the processing qualified rate of the product is more than 95%. The auxiliary processing method for the slender shaft of the common lathe is proved to be reasonable and reliable. And the yield of direct processing is about 60%. By means of the auxiliary device, the slender shaft machining yield of the aviation product is improved, and machining quality is improved. The problem of the slender axles of aviation products great runout in the course of working is solved.
The auxiliary machining device for the slender shaft of the aviation product comprises a self-made bolt, a bracket and a supporting roller; the self-control bolt is equipped with screw thread A and screw thread B, and screw thread A and leg joint, screw thread B and the inner chamber outside screw hole phase-match on the supporting roller, are equipped with one section optical axis in the middle of two sections screw thread A and screw thread B, and the optical axis diameter is less than screw thread B diameter. One end of the support roller is provided with a threaded hole matched with the thread B of the self-made bolt, the bottom of the threaded hole is provided with an inner cavity, and the diameter of the inner cavity is larger than that of the thread B of the self-made bolt; the other end is provided with two rollers which are symmetrically distributed.
The support is provided with a hole for injecting cooling liquid, a connecting fixing hole connected with a lathe and a position adjusting groove.
The roller material can be changed according to different processing materials, for example, ceramic or rubber rollers can be used for processing magnetic materials.
