Magnetic drive type tapered hole inner surface strengthening equipment

Abstract

The invention discloses a magnetic force-driven tapered hole inner surface strengthening device in the field of parts surface treatment. The bottom of the cylinder body is vertically placed with a workpiece, and the workpiece is provided with a tapered hole whose large end faces directly above. , the center of the top cover has a top cover through hole communicating with the taper hole, a piston is arranged in the top cover through hole, the piston is fixedly connected to the lower end of the connecting rod coaxially, and the upper end of the connecting rod extends upwards out of the top cover and is fixed Connect the slider, the slider is slidably connected with the upper and lower vertical guide rails, the slider is fixedly connected to one end of the transmission rod at the same time, and the other end of the transmission rod is fixedly connected to the edge of the disc arranged horizontally on the central axis, and the disc is fixedly connected to the center of the shaft. One end of the commutator piece, the other end of the commutator piece is fixedly connected to the coil, the coil is horizontally placed between a pair of magnets, the commutator piece is in contact with the brush, and the brush is connected to the power supply through a wire; the volume is driven alternately by magnetic force, Cavitation enhancement is caused by changing the liquid pressure in the volume, and the strengthening effect is good.

Description

technical field [0001] The invention belongs to the field of parts surface treatment, in particular to equipment for strengthening and processing the inner surface of a tapered hole. Background technique [0002] At present, the precision requirements of mechanical equipment and mechanical products are getting higher and higher. Tapered holes are widely used in various mechanical parts due to their high positioning accuracy. However, it is relatively difficult to process tapered holes. Due to the fatigue performance of the inner surface It has a great impact on the performance of mechanical parts, so the quality of the inner surface of the tapered hole is high. The mechanical properties of the inner surface of the hole can be improved through the strengthening process of the inner surface of the tapered hole, thereby improving the fatigue life of the part. [0003] Most of the existing hole inner surface strengthening processes adopt mechanical shot peening and cold extrusio...
