Description
Technical field
The utility model relates to a kind of on-bne repair device of large-scale favourable turn, particularly a kind of online finish turning of large-scale favourable turn axle journal and lapping device.
Background technology
Large-scale favourable turns such as Turbo-generator Set, hydroelectric generation unit, boats and ships; Because operation throughout the year; The rotor journal position of these large-scale favourable turns is pulled and is worn and torn through regular meeting, produces bigger dimensional discrepancy, and the deviation of rotor journal is excessive; Can influence the security of operation of unit, rotor journal is pulled and is worn and torn and need carry out repair process.
When repairing these large-scale favourable turn axle journals, earlier with high energy precision welding assisting vehicle with the pulling and fray of the method repairing axle journal of soldering, repair satisfactory new standard to axle journal with finish turning and abrasive method again.For the axle journal after repairing is carried out repair process; In the prior art; Need extract armature spindle from large-scale favourable turn, transport to the maintenance shop to armature spindle, on lathe and grinding machine, repair satisfactory new axle standard to axle journal with finish turning and abrasive method in the maintenance shop.
This repair process method will be extracted armature spindle out using large-scale favourable turn of field stripping and relevant jockey, is transported to the maintenance shop to armature spindle, and the repairing rotor axle journal in the maintenance shop transports back and uses assembled on site, take a lot of work, time-consuming, bother very much.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, proposes a kind of saving of labor, saves time, comparatively simply repairs pulling and the online finish turning of large-scale favourable turn axle journal and the lapping device of the usefulness of wearing and tearing of large-scale favourable turn rotor journal.
The utility model is realized with following method.
Online finish turning of large-scale favourable turn axle journal and lapping device have large carrying food-basket and two circular boop rings that semicircular ring connects to form, and the left and right two ends of large carrying food-basket have the annulus that is connected to form by two semicircular ring respectively, and the excircle of left and right annulus is dynamic wheel for inputting respectively; Be uniformly distributed with the connecting rod that is connected with the parallel axes of large carrying food-basket between the left and right annulus, be connected with knife rest slideway and the leading screw parallel between the left and right annulus, the knife rest that can on slideway, slide is arranged on the knife rest slideway with connecting rod; The screw that matches with leading screw is arranged on the knife rest; Pass the screw of leading screw from knife rest, leading screw has the leading screw head that passes large carrying food-basket one end annulus, is connected with the driving cam with click on the leading screw head; The shifting block that matches with driving cam is arranged on the circular boop ring; Be uniformly distributed with 4 radially slideways on the annulus along the circumference, positioning sliding block is arranged on the slideway, between slideway and the slide block securing member is arranged.
During use, on-the-spot in the use of large-scale favourable turn, be fastened on pulling of large-scale favourable turn rotor journal and fray to large carrying food-basket of the utility model and circular boop ring; The radial protrusion of shifting block on the circular boop ring and driving wheel excircle is relative, connects motor at the power input wheel of left and right annulus excircle through transmission device, is positioning reference with the not wear surface of large-scale favourable turn rotor journal; Regulate the radially positioning sliding block on the slideway of annulus upper edge circumference, be against the inner of slide block on the not wear surface of large-scale favourable turn rotor journal, let large carrying food-basket axis and large-scale favourable turn rotor journal axis on same straight line; Lathe tool is installed on knife rest; Blade is against pulling and fray one side after the soldering of large-scale favourable turn rotor journal, keeps rotor journal in inactive state, opens motor; Large carrying food-basket rotates around rotor journal; Large carrying food-basket whenever turns around, be fastened on the shifting block on the circular boop ring on the axle journal stir have click driving cam once, drive leading screw and rotate an angle; Leading screw rotates an angle and can drive knife rest and move along the axis of rotor journal and move a step; Pulling and the opposite side of fray after the soldering that moves to rotor journal, the lathe tool on the knife rest can be pulling and the processing of fray finish turning after the rotor journal soldering, and rotor journal is pulled and fray can wrap up abrasive belts after through finish turning processing between knife rest slideway and rotor journal; Open motor; To after the rotor journal finish turning processing pull and fray grinds, pull and the rotor journal that weares and teares through finish turning and attrition process, repair satisfactory new standard.
The utility model is simple in structure, and is easy to use, can be at the use scene of large-scale favourable turn pulls and the rotor journal of wear-out defect is implemented to repair having; Need not dismantle large-scale favourable turn and relevant jockey, extract armature spindle out, be transported to the maintenance shop to armature spindle; The repairing rotor axle journal in the maintenance shop transports back a series of operations such as using assembled on site again, the saving of labor, saves time, repairs conveniently; Can shorten maintenance duration, practice thrift a large amount of maintenance funds.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
