It is a further object to provide a kind of polishing process of polishing operation device based on track polishing operation,
Specifically includes the following steps:
Step S1: personnel are operated first by polishing operation device and move arrival designated place, wherein polishing operation device
Rail running wheels are contacted with rail surface, and the rib circular arc of side wheel is bonded with survey circular arc in rail, and operator pushes polishing
Apparatus for work back and forth carries out no less than 30 meters on rail surface, and rail running wheels is made to contact complete fitting with rail surface；
Step S2: after the completion of step S1, operator pushes polishing operation device to move on rail, using being mounted on
Laser flaw detection instrument on polishing operation device detects rail surface scar, and laser flaw detection instrument detects the design parameter of scar:
Cup depth, notch area, recess length, the design parameter and scar position coordinate that laser flaw detection instrument will test return
It reaches on the one chip microcomputer MCU of polishing operation device, wherein one chip microcomputer MCU is according to laser flaw detection instrument
The design parameter for detecting scar, selects corresponding polishing program；
----------------------------------------------------------------
Step S3: after the corresponding polishing program of selecting step S2, the grinding wheel driving motor of polishing operation device starts
Rotation, revolving speed gradually rises to 6000rpm, during this, horizontal movement platform, the X of vertical motion platform, Y-direction straight line mould
Group drives polishing wheel shaft to be moved to specified coordinate position, and the Y-direction of vertical motion platform is progressively fed, until grinding wheel and rail
Spark is polished, polishing operation formally starts；
Step S31: when polishing initial, horizontal movement platform and vertical motion platform drive grinding wheel and rail to knife
When occurring grinding wheel and rail buffed surface excessive contact in the process, spline housing first passes through baffle and contacts with compressed spring, pressure
Contracting spring stress is shunk, and compressed spring contraction information is sent to one chip microcomputer by the sensor near compressed spring
MCU；

The device that rings issues qualified buzzer or light flash, when not meeting detection result, repeats step S2-4.
Preferably, in step s 4, encoder, encoder main shaft and track can also be used in monitoring rail wheel travel distance
Walking is connected, and encoder will record circle number and the position of rotation.
Preferably, polishing program in step 2 is α ° of grinding angle for adjusting upper rail face, polish length β, with recessed
Centered on falling into, left and right 1m range is polished number 10+N times, and every time after polishing, grinding wheel auto-feed 0.1mm is both to beat every time
Grind Distance Shortened 5-8%, wherein N=β/1m.
Advantages of the present invention and good effect are:
1, the present invention is on the basis of two automatically controlled linear motion platforms, to polishing apparatus for work rotating mechanism and polishing
Apparatus for work improves, and makes it possible to solve existing polishing operation device and contacts in polishing rail level and track
The problem of face can not accurately polish, the polishing operation device that forges iron can be replaced different in operation according to the difference of work surface
Grinding wheel is polished, and routinely when polishing rail upper surface, imitation profile, a bowl sand loading wheel can be used, pass through grinding wheel spindle angle
Variation, selection are polished upper rail level and imitation profile, when polish fat edges when, the replacement bigger plate-like grinding wheel of diameter, this grinding wheel is due to connecing
Contacting surface machine is big, and grinding wheel diameter is big, and grinding efficiency is higher, only needs the replacement polishing wheel shaft in polishing wheel shaft mounting base at this time, more
It can polish fat edges after changing, drive the motor of grinding wheel defeated with rail contact transition damage in addition, also solving grinding wheel
The problem of shaft and motor.
2, main shaft anticollision cutter mechanism is added on the synchronous belt main shaft of polishing operation device rotating mechanism of the invention, so that together
Be elastic mechanism between step band main shaft and grinding wheel, can in grinding wheel first contacts guide rail, buffer grinding wheel and grinding wheel spindle it
Between axial force, reduce the probability of grinding wheel spindle damage, while dynamic head is excessive between grinding wheel spindle and grinding wheel, power head with
Grinding wheel spindle is driven by the way of synchronous belt, further reduced grinding wheel spindle due between grinding wheel and rail the amount of feeding it is too big
Overload is caused to damage.
3, the full resin structure that rail running wheels of the invention use, mainly prevents using two iron when metal track wheel
It is on-insulated between rail, conducting is formed, and with when by there is the rail of linking, the railway system is judged between siding track two wheels
There are the error messages such as train process at this time, has side wheel on the outside of resin wheel, mainly undertake polishing operation device and pushed away in land
When row, rail wheel and ground face contact supporting role prevent resin wheel surface gouge.
4, this invention also solves on the polishing operation device rotating mechanism of previous all electrically driven (operated) polishing operation devices
Polishing operation device polishing be occur polishing operation device rotating mechanism trembling the problem of, main cause is motor or subtracts
The inside of fast device usually passes through gear and is driven, whatsoever the gear of shape, in engagement process, due to gap factor
In the presence of teeth can not be at a fully engaged with teeth, and due to being by the defeated of motor or retarder between support frame and rotating turret
Shaft directly or indirectly drives its rotation, and when support frame and rotating turret are remain stationary is also the dimension direct or indirect by output shaft
Hold it is static so that in motor or retarder there are when above-mentioned reason, when support frame and rotating turret are static, due to polishing operation
The reason of device rotates, also will drive support frame and trembles with rotating turret, and the application passes through installation braking on the support frame
Mechanism, arrestment mechanism are braked support frame and rotating turret using the form of brake disc and brake block, on the one hand can be protected
Demonstrate,prove support frame and with rotating turret keep opposing stationary completely during the grinding process, on the other hand relatively simple for structure, weight compared with
Movement that is low, not interfering vertical motion platform, horizontal movement platform also.
