Description
Technical field
The present invention relates to a kind of sander of the rail for polishing orbit, this sander comprises support frame, this support frame is designed to roll at rail by tracer roller, and has adjustable polishing unit, support frame is mounted to by the pivot driver device and pivots at assembly fixture, assembly fixture has and is designed to the guide roller that rolls at rail, wherein, in tracer roller and the guide roller each has and is arranged for the corresponding rolling surface that rolls at rail head, and the guiding parts that is designed to be applied to rail head is connected to assembly fixture in the mode that allows to separate a distance with respect to support frame.
Background technology
Such sander can be recognized from US 5 735 734, is mainly used in eliminating the coarse point that appears at after wiping out weld seam on the rail head surface.
Summary of the invention
The sander that the purpose of this invention is to provide the type that a kind of beginning mentions, the polishing effect can utilize this sander to improve.
According to the present invention, this purpose realizes by the sander of following particular types, wherein, separating a distance in the direction perpendicular to pivot axis between guiding parts and the support frame, is to realize by the gear drive that is rotatably connected to the pivot driver device.
Because this structure, the transverse movement of guide roller are coupled to the pivoting action of polishing unit and are accurately limited.By means of this, guarantee all the time the accurate location of assembly fixture, and uniform high polishing quality thus.
Additional advantage of the present invention is described by dependent claims and accompanying drawing and is become apparent.
Description of drawings
Below in conjunction with the embodiment shown in the accompanying drawing the present invention is described in more detail, in the accompanying drawing:
Fig. 1 shows the lateral view of sander, and Fig. 2 and Fig. 3 show the simplification cross section of cutting open along the line II among Fig. 1 or III separately, and Fig. 4 shows the phantom drawing of the part of sander.
The specific embodiment
To seen in fig. 4, the sander 1 that is used for the rail 2 of polishing orbit comprises support frame 3, and basically describes in detail in US 5 735 734 such as Fig. 1.Sander 1 is supported on the rail 2 that will polish and is designed to and rolls at rail 2 via two tracer rollers 4, tracer roller 4 is spaced apart from each other at the longitudinal direction of rail, and has axis of rotation 5.Support frame 3 is connected to assembly fixture 8 so that can be around pivot axis 7 rotations at two vertical ends, and this pivot axis 7 extends and formed by axle 6 at the longitudinal direction of rail, and assembly fixture 8 is provided with and projects upwards the also yoke 9 of bridge joint support frame 3.
Being positioned on the carriage 10 that is fixed to assembly fixture 8 is drive motors 11, and this drive motors 11 is connected to the polishing unit 13 that is arranged on the support frame 3 via flexible drive shaft 12.Polishing unit 13 is comprised of polishing pad 16, and this polishing pad 16 can and be designed to be placed on the rail head 15 of rail 2 around rotation 14 rotations.Be provided with cantilever support (referring to the Fig. 7 among the US 5 735 734), be used for assembly fixture 8 is supported on the rail on opposite, not shown.
The guide roller 17 and the tracer roller 4 that are connected to assembly fixture 8 all have the rolling surface that is arranged in rail head 15 rollings, are labeled as respectively 18 or 19 (specifically referring to Fig. 3, Fig. 4).Pivot driver device 20 is arranged for support frame 3 is pivoted with respect to assembly fixture 8.Described pivot driver device 20 forms (referring to Fig. 2) by handwheel 21, screw rod 22 and two sector gears that are engaged with each other 23.The sector gear 23 of bottom is connected in support frame 3.
Also can be fixed to roller seat 25 around each guide roller 17 of roller axis 32 rotations as guiding parts 24, roller seat 25 is supported on the assembly fixture 8, be used for pivoting around axis 26, it is spaced apart that axis 26 is parallel to pivot axis 7 extensions and in the vertical direction and pivot axis 7, and roller seat 25 is rotatably connected to gear drive 27.Gear drive 27 is formed by the sector gear 28 that is connected to roller seat 25, and sector gear 28 is via commutation cogwheel 29 and cogwheel 30 engagements.Cogwheel 30 is positioned to axle 6 coaxial, and rotatably is connected with support frame 3.
In Job Operations, sander 1 passes through manually to turn round at rail 2, and locates to move around at the polishing point.During this period, assembly fixture 8 always remains in vertical position, and different from support frame 3 be that this assembly fixture 8 does not pivot.This provides following advantage: be correct mode of operation aspect ergonomics, the operator is in comfortable orthostatism, can carry out all adjusting operations by the control element that is arranged in yoke 9 tops.In addition, owing to drive motors 11 does not tilt, so it can be the form with noise four-stroke engine still less of better discharge value, generation.
When horizontally extending when surface of polishing rail head 15, sander 1 is in the position shown in Fig. 1 to Fig. 4.Support frame 3 is resisted against on the rail 2 via tracer roller 4, and the axis of rotation of tracer roller 4 is flatly directed 5 this moments.Assembly fixture 8 similarly is resisted against on the tracer roller 4, and guide roller 17, because its roller contact point is positioned at higher position, so be not resisted against (referring to Fig. 3) on the rail 2.The size of the wheel rim of guide roller 22 is determined by this way, so that they extend beyond the rail head top edge downwards, thereby plays the effect of guiding parts 24, prevents that sander 1 is from rail head 15 side direction slippages.The operator controls the feed speed of polishing pad 16 by pivot driver device 20, and wherein, the deadweight of device 1 produces the required contact of sanding operation.
If the vertical side surface of adjacency of rail head edge or rail head 15 is carried out operation, then only need by activating handwheel 21 support frame 3 to be pivoted for this reason.Axle 6 causes tracer roller 4 to tilt around the rotation that is associated of pivot axis 7, and tracer roller 4 is because of the identical lateral contour of following rail head 15 with the profiling roller of its function.The longitudinal direction displacement that this also automatically makes support frame 3 and is transverse to rail via the assembly fixture 8 that axle 6 connects.
For the required one-movement-freedom-degree in a lateral direction of this purpose by roller seat 25 in a lateral direction along with axle 6 and the rotatablely moving of gear drive 27 that connect with it pivot to realize.The forward or backwards pivoting action of roller seat 25 is all delimited by stop part 31 in all cases.
