Specifically execute mode
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, full-automatic detector for straightness of elevator guide rail has detection platform 1, detects carrying roller 2 and is located at a side on the detection platform 1, and testing stand 3 is positioned at detection platform 1 one sides, and this testing stand 3 is the lifting testing stand.Detect carrying roller 2 and be positioned at testing stand 3 inboards.Testing stand 3 lower ends are provided with original position switching mechanism 4 (as shown in Figure 3), present embodiment Central Plains bit flipping mechanism 4 constitutes by knocking over cylinder 41 and returning cylinder 42, this structure only is wherein a kind of of switching mechanism, also can adopt the switching mechanism of other structure, be not limited to the structure of mentioning in the present embodiment.Testing stand 3 two ends are respectively equipped with conveying roller 5, and horizontal positioning device 6 is arranged on testing stand 3 one sides, and longitudinal positioning device 13 is located at testing stand 3 two ends respectively.Described horizontal positioning device 6 and longitudinal positioning device 13 all adopt cylinder, also can adopt other can replace device.Detection platform 1 is provided with pick-up unit, and pick-up unit comprises CCD laser displacement sensor 7 and displacement transducer travel mechanism.Described displacement transducer travel mechanism comprises line slideway 8, displacement motor 9, gear (not shown), tooth bar 11, and line slideway 8 is located on the detection platform 1, and tooth bar 11 is located at line slideway 8 one sides.CCD laser displacement sensor 7 and displacement motor 9 are arranged on the same detection dolly 12, gear is arranged on this detection dolly 12 bottom surfaces, detecting dolly 12 is arranged on line slideway 8 and the tooth bar 11, wheel and rack 11 is meshed, and CCD laser displacement sensor 7 and mobile motor 9 are controlled by computer control system respectively.11 combinations of its middle gear, tooth bar can also adopt the combination of other form to replace, the gear, tooth bar 11 combinations that are not limited in the present embodiment to be mentioned.Also be provided with ink jet numbering machine 14 on the described detection platform 1, ink jet numbering machine 14 is controlled by computer control system.
The course of work of whole machines is: initial detecting frame 3 is in the rising state, and guide rail 15 to be measured passes through conveying roller 5 automatic feeds to testing stand 3.Longitudinal positioning device 13 adopts cylinder, and the cylinder axis of the longitudinal positioning device 13,13 at testing stand 3 two ends rises guide rail 15 to be measured is positioned between the longitudinal positioning device 13,13.Testing stand 3 descends, and guide rail 15 to be measured drops on and detects on the carrying roller 2, and horizontal positioning device 6 adopts cylinder, and its cylinder axis stretches out guide rail 15 located lateral to be measured.CCD laser displacement sensor 7 in the pick-up unit moves at the control lower edge of computer control system line slideway 8, the linearity that the side of guide rail 15 to be measured is carried out detects, handle detecting data by computer system, obtain the linearity of guide rail to be measured 15 sides.After the side of guide rail 15 to be measured is detected and is finished, the cylinder axis of horizontal positioning device 6 and longitudinal positioning device 13 is retracted to original position, cylinder 41 cylinder axis of knocking in the original position switching mechanism 4 rise, guide rail 15 to be measured is carried out 90 degree upsets, the cylinder axis of horizontal positioning device 6 and longitudinal positioning device 13 stretches out guide rail to be measured 15 location, begin the end face of guide rail 15 to be measured is carried out the linearity detection, and in the 15 end face codings of qualified guide rail to be measured, comprise product type, date of manufacture, guide rail numbering etc., this information is stored by computer system equally, so that inquire about later on.After coding finishes, the cylinder axis that returns cylinder 42 in the original position switching mechanism 4 rises, the cylinder axis of knocking over cylinder 41 simultaneously descends, the cylinder axis of horizontal positioning device 6 and longitudinal positioning device 13 is retracted to original position, guide rail 15 after the detection is returned original position and puts well under the acting in conjunction of above-mentioned cylinder, testing stand 3 rises, and guide rail 15 leaves and detects carrying roller 2, guide rail 15 after conveying roller 5 will detect is sent, and entire work process finishes.
