Embodiment Construction

[0028] Such as Figure 1 to Figure 3 As shown, a laser inner hole quenching device includes a workpiece holder 1 , a laser quenching head 2 and a follower seat 3 .

[0029] Please refer to figure 1 and image 3 , the workpiece frame 1 is used to support a metal workpiece with an inner hole, and the upper surface of the workpiece frame 1 is provided with a workpiece positioning groove 5 matching the shape of the workpiece 4 . The bottom of the workpiece holder 1 is provided with a distance from the ground for assembling the follower 3, and the follower 3 can be sent in from the bottom of the workpiece holder 1 and then lifted up to surround the both sides of the workpiece holder. The two legs of the workpiece rack 1 are provided with strip holes, and the strip holes are fastened with horizontal supporting plates 6 by bolts. The installation height of the supporting plates 6 in the strip holes can be adjusted. Before assembling the follower seat 3 , move the supporting plate ...

Abstract

The invention provides a laser inner hole quenching device. The device comprises a workpiece frame, a laser quenching head and a following seat. The laser quenching head comprises a casing, a collimating mirror and focusing mirrors, the collimating mirror is horizontally installed in the casing, the focusing mirrors are positioned below the collimating mirror and have a frustum-shaped focusing mirror surface, and a horizontal pulling plate is installed outside the casing. The following seat comprises a U-shaped seat body, a mirror seat installed on the seat body, a first total reflection mirror, a support column and a second total reflection mirror, two longitudinal sides of the seat body pass through the left and right sides of a workpiece respectively and then are installed on the horizontal pull plate, and the mirror seat vertically extends into an inner hole of the workpiece and can move synchronously with the laser quenching head; and after passing through the collimating mirror,a laser beam is reflected by the second total reflection mirror to the focusing mirrors, and is then reflected downward by the focusing mirrors to form an annular laser beam, and the annular laser beam is reflected to the inner hole wall of the workpiece after reaching the first total reflecting mirror. The problems of low processing efficiency, clunky structure, high energy consumption and insufficient processing precision of workpiece inner hole quenching can be solved.

Description

technical field [0001] The invention belongs to the technical field of laser quenching, and in particular relates to a laser inner hole quenching device. Background technique [0002] Laser quenching is a quenching technology that uses a laser to heat the surface of a material above the phase transition point. As the material itself cools, austenite transforms into martensite, thereby hardening the surface of the material. Laser quenching has high power density and fast cooling rate, which is a clean and fast quenching process. [0003] For the laser hardening of the inner hole of the workpiece, since the inner hole needs to be quenched in the circumferential direction and axial direction, and the laser beam reflected on the inner hole of the workpiece is usually in the shape of a beam, it is necessary to scan the laser beam on the circumference for one week to complete Quenching in one circle, the processing efficiency is low; and the laser quenching equipment is usually e...
