The scraping process can form multiple recesses on the contacting surfaces of the conventional hard rail. The recesses can be used to store lubricant to lubricate movement of a moving element on the hard rail.
  • Detecting a surface roughness of the scraped surface is very important to maintain functions of the conventional hard rail, since the surface roughness may affect mobility of the moving element on the conventional hard rail. A conventional method for determining the surface roughness of the scraped surface comprises the following steps: painting ink on the scraped surface, sliding the moving element on the scraped surface so ink on a higher area will be removed and be found, and measuring a height of the higher area with a measuring tool. In addition, a charge-couple device (CCD) can be used to screen the inked-scraped surface to analyse the surface roughness of the conventional hard rail.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference to FIGS. 1 to 3, a method of auto scanning and scraping a work piece (30) for a hard rail in accordance with the present invention comprises a preparing step, a scanning step, a detecting step, an auto-scraping step and an analyzing step.
  • The preparing step comprises preparing an auto scanning and scraping apparatus. The auto scanning and scraping apparatus comprises a multi-axis machine tool, a control computer (20), an auto-scraping device (13) and a position detector (12).
  • The multi-axis machine tool has three linear axes (X-, Y- and Z-axes), at least one rotation axis, a spindle (11), a moving mount (10) and a turntable (14). The spindle (11) is defined along the Z-axis of the multi-axis machine tool. The moving mount (10) is defined below the spindle (11), is moved relative to the spindle (11) by the rail devices (not numbered) on the X-axis and the Y-axis of the multi-axis machine tool and has a top. The turntable (14) is rotatably mounted on the top of the moving mount (10) below the spindle (11). A work piece (30) for the hard rail is put on the turntable (14) and has a surface.
  • The control computer (20) is electrically connected to the moving mount (10) of the multi-axis machine tool. The auto-scraping device (13) is mounted securely on the spindle (11) above the moving mount (10) and has an extending mount (131) and a scraping tool (132). The extending mount (131) is securely mounted on a bottom of the spindle (11) and has a bottom side. The scraping tool (132) is movably mounted on the bottom side of the extending mount (131) and has a sidewall. The position detector (12) is mounted on the sidewall of the scraping tool (132), is electrically connected to the control computer (20) and has a scanning terminal (121) contacted to scan the surface of the work piece (30). Preferably, the position detector (12) is a triangle-laser position detector.
  • After mounting the position detector (12) on the auto-scraping device (13), a height of the spindle (11) is adjusted relative to the turntable (14) to let the valid measurement range of the position detector (12) cover the whole surface of the work piece (30).
  • The scanning step comprises moving the turntable (14) relative to the spindle (11) to let the scanning terminal (121) of the position detector (12) move along an S-shaped route to scan the surface of the work piece (30). Preferably, the interval between the adjacent paths of the S-shaped route is a constant value. After scanning the surface of the work piece (30), an initial scan point and a measurement range are set in the control computer (20) and location of position detector (12) in the Z-axis direction is compensated for to eliminate an offset mistake produced by vibration of the turntable (14) in the scanning process. When the offset mistake of the turntable (14) has been corrected by the control computer (20), the surface of the work piece (30) is scanned along the setting route to read the roughness value of the work piece (30) and the data is transferred to the control computer (20).
  • The detecting step comprises forming a 3D-appearance drawing of the work piece (30) by the scanning data in the control computer (20). When the 3D-appearance drawing of the work piece (30) has been formed by the control computer (20), the contacting ratio per square inch is detected, including, numbers of the high points per square inch, height distributed mode, straightness of the surface and corner shape of the 3D-appearance drawing of the work piece (30). Coordinates of the 3D-appearance drawing of the work piece (30) that fail to meet requirement of preceding detection steps are transferred and a scraping route planned. The scraping route is translated into a NC (Numerical Control) code and the NC code is transmitted to the multi-axis machine tool to control movement of the multi-axis machine tool.
  • The auto-scraping step comprises scraping the surface of the work piece (30) by the auto-scraping device (13) that is moved and controlled by the multi-axis machine tool. Preferably, before scraping the surface of the work piece (30), the surface of the work piece (30) is scraped to confirm with an actual scraping depth of the scraping tool (132) and the scraping process is corrected according to the actual scraping depth of the scraping tool (132).
  • The analyzing step comprises scanning the surface of the work piece (30) after the auto-scraping step, forming a 3D-appearance drawing by the scanning data in the control computer (20) and detecting the 3D-appearance drawing of the work piece (30) that has been scraped with the preceding detection steps. If the 3D-appearance drawing of the work piece (30) meets requirements of the preceding detection steps, the auto scanning and scraping procedures is finished. If the 3D-appearance drawing of the work piece (30) fails to meet requirements of the preceding detection steps, the auto-scraping step is repeated to scrape the surface of the work piece (30) by the auto-scraping device (13) to meet the requirement of the preceding detection steps.
  • The method of auto scanning and scraping a work piece (30) for a hard rail in accordance with the present invention only needs to put a work piece (30) on the turntable (14) and the position detector (12) can scan the surface of the work piece (30) and a 3D-appearance drawing of the work piece (30) is formed in the control computer (20) by the scanning data, and the auto-scraping device (13) can automatically scrape the work piece (30) that fails to meet the requirement of the preceding detection steps to meet the requirement of the preceding detection steps. Therefore, the method of auto scanning and scraping a work piece (30) for a hard rail in accordance with the present invention can scrape the surface of the work piece (30) quickly and accurately by the multi-axis machine tool, the control computer (20), the auto-scraping device (13) and the position detector (12) of the auto scanning and scraping apparatus.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
