An automatic alignment device and method

Abstract

The invention discloses an automatic alignment device, which comprises an axle box fixed support hanger, a tightening shaft fixed revolving box, and an axle box servo drive motor, which is connected with the axle box fixed support hanger and can drive the tightening shaft to fix The transfer box is rotated; the real-time camera position feedback module of the axle box is tightened, and it is connected with the fixed support hanger of the axle box, and the image of the hole position of the wheel set moving under the slide rail can be taken; the positioning device is connected with the axle box It is connected to the fixed support hanger of the box; the position information of the wheel set can be collected, matched with the image of the hole position of the wheel set taken, and the servo drive motor of the axle box is controlled to drive the tightening shaft to fix the rotary box to rotate to achieve tightening Automatic alignment of shaft fixing turrets and wheel set holes. The invention also discloses an automatic alignment method. The automatic alignment device of the present invention automatically completes the addressing and positioning operations for multiple wheel sets, realizes the automatic tightening operation of the wheel sets, saves manpower, and improves the operation efficiency and precision.

Description

technical field [0001] The invention belongs to the technical field of wheel set maintenance equipment, and more specifically relates to an automatic alignment device and method. Background technique [0002] At present, the multi-axis simultaneous tightening and assembly of the CRH3 Harmony EMU wheel-to-axle end gland fastening bolts in the railway industry mainly adopts a horizontal trolley type calibration device, which is mainly composed of bottom wheels, steel structure racks, handrails, simulation The shaft end and the left and right outriggers are combined. [0003] At present, the maintenance and assembly workshops of EMU depots and EMU operating stations all over the country are mainly used for the tightening and assembly of the fastening bolts of the wheel set shaft end glands of the CRH3 Harmony EMU. There are mainly the following types: (1) Truss slide rail + Single rope suspension multi-spindle nutrunner. The way to realize it is to fix and install multiple ti...

Problems solved by technology

The main body is a gantry frame structure that can slide on the ground track. Although the main structure of the equipment will not block the traveling path of the crane hook and has little effect on the hoisting of the crane in the workshop, the main body of the equipment will occupy a part of the length, reducing the number of workshops. The number of workpieces placed on the workbench; in addition to manually moving and tightening the axle box booster arm, the operator also needs to hold the remote control to operate the gantry slide rail to move along the ground track, which increases the workload

When using multi-axis tightening, it is necessary to manually slide the power-assisted arm to feed; when aligning, the operator needs to visually measure the angular position of the workpiece hole, and then manually rotate the axle box to a certain angle to perform alignment. The data cannot be quantified and stored. The dependence is large, and the manual participation is relatively high
