Magnetic driving type taper hole inner surface strengthening equipment

Abstract

The invention discloses magnetic driving type taper hole inner surface strengthening equipment in the field of part surface treatment. A workpiece is vertically arranged at the bottom in a cylinder body, a taper hole with a large end facing right above is formed in the workpiece, a top cover is arranged right above the workpiece, a top cover through hole communicating with the taper hole is formedin the center of the top cover, a piston is arranged in the top cover through hole, the piston is coaxially and fixedly connected to the lower end of a connecting rod, and the upper end of the connecting rod extends upwards out of the top cover to be fixedly connected to a sliding block; and the sliding block is in sliding connection with a vertical guide rail, the sliding block is fixedly connected to one end of a transmission rod at the same time, the other end of the transmission rod is fixedly connected to the edge of a disc which is horizontally arranged at the center shaft, the disc iscoaxially and fixedly connected to one end of a reversing sheet, the other end of the reversing sheet is fixedly connected to a coil, the coil is horizontally placed between the pair of magnets, the reversing sheet is in contact with an electric brush, and the electric brush is connected to a power supply through a wire; and volume alternating is driven by magnetic force, the pressure of the liquid in the volume is changed so as to perform cavitation strengthening, and the reinforcing 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...
