A positioning mechanism is installed at the bottom of the V-shaped groove capable of rotating by 360 degrees, a spring positioning pin is arranged on the positioning mechanism, positioning holes which are symmetrically distributed by 180 degrees are formed in the side walls of the vertical column, and the height of the positioning holes is the same as that of the spring positioning pin. By the adoption of the V-shaped grooves, the angle of a line of centers of two end holes of a bar is observed, and the lead of the bar is calculated according to the angle and the diameter and the length of the bar. By the adoption of a rotating device and the positioning holes, the end faces of the bar are automatically positioned to be perpendicular to the camera, the bar does not need to be touched or moved, and therefore detection accuracy is guaranteed. The camera is used for projecting inner holes in the two end faces of the bar to be detected and a connecting line of the inner holes on the same plane, the included angle of the line of centers of the inner holes is measured, and the lead is calculated according to the screw lead and the angle principle.
Description
Technical field
The present invention relates to the pick-up unit of cold threaded hole helical pitch in a kind of wimet, for the helical pitch of cold threaded hole bar or cutter in wimet, detect and other general measuring methods cannot detect the bar-shaped object of endoporus helical pitch information.
Background technology
At present, domestic wimet manufacturer adopts to the detection of cold threaded hole bar lead of screw in wimet the method that external thread helical pitch identifies interior cold threaded hole helical pitch of measuring conventionally, because interior cold threaded hole internal and external threads helical pitch exists certain error, and this detection method requires also higher to operating personnel's technical ability, error is generally at ± 1mm, therefore, by external thread helical pitch, cannot reflect accurately endoporus lead of screw.Cutter manufacturer during cold helical tooth blade, owing to detecting the difference of helical pitch and actual endoporus helical pitch, especially, when making sword is grown up in 100mm cutter, due to cumulative errors, easily causes endoporus to be opened brokenly in processing during fluting.
And offshore company adopts the endoporus lead of screw of measuring bar to identify helical pitch information, although accuracy of detection is higher, checkout equipment principle used is complicated, and expensive.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, cold threaded hole helical pitch measuring instrument in a kind of wimet is provided.
Object of the present invention is achieved through the following technical solutions:
Cold threaded hole helical pitch measuring instrument in wimet, feature is: comprise base, can 360 ° rotate V-type groove, slip V-type groove and cameras, on base, be vertically installed with column and jacking gear, column upper end is installed and can 360 ° to be rotated V-type grooves, can on 360 ° of rotation V-type grooves, slip V-type groove be installed, camera is installed in jacking gear upper end; Described bottoms of can 360 ° rotating V-type grooves be provided with detent mechanism, and detent mechanism is provided with spring sheet-holder, and the sidewall of column is provided with and is 180 ° of symmetrical pilot holes, and the height of pilot hole is consistent with the height of spring sheet-holder.
Further, cold threaded hole helical pitch measuring instrument in above-mentioned wimet, wherein, a V-type groove is installed in described jacking gear upper end, on V-type groove, camera is installed.
Further, cold threaded hole helical pitch measuring instrument in above-mentioned wimet, wherein, describedly can 360 ° rotates V-type grooves and comprise slew gear and V-type groove placed on it.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Adopt V-type groove, the angle of the two stomidium lines of centres of observation bar, calculates the helical pitch of bar by angle, bar diameter, length gauge.Adopt whirligig, be provided with pilot hole, can automatically locate bar perpendicular to camera, do not need to contact mobile bar, guaranteed the accuracy detecting.By camera, bar both ends of the surface endoporus to be measured is projected on same plane, by both ends of the surface endoporus center difference line, measure the angle angle of line, according to lead of screw, angle principle, calculate bar helical pitch to be measured.Simple for structure, measurement result accurately and reliably.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: organigram of the present invention.
Embodiment
As shown in Figure 1, cold threaded hole helical pitch measuring instrument in wimet, comprise base 1, can 360 ° rotate V-type groove 3, slip V-type groove 4 and cameras 8, on base 1, be vertically installed with column 2 and jacking gear 5, column 2 upper ends are installed and can 360 ° to be rotated V-type grooves 3, can on 360 ° of rotation V-type grooves 3, slip V-type groove 4 be installed, a V-type groove is installed in jacking gear 5 upper ends, and camera 8 is installed on V-type groove; Can detent mechanism 6 be installed 360 ° of bottoms of rotating V-type groove 3, detent mechanism 6 is provided with spring sheet-holder, and the sidewall of column 2 is provided with and is 180 ° of symmetrical pilot holes 7, and the height of pilot hole 7 is consistent with the height of spring sheet-holder.
Wherein, can comprise slew gear and V-type groove placed on it by 360 ° of rotation V-type grooves 3.The angle of V-type groove is 90 °.
Bar to be measured is placed on and can 360 ° rotates on V-type grooves 3, if bar is too short, need be placed on slip V-type groove 4, by spring sheet-holder, coordinate and keep center line consistent with pilot hole 7, after camera is taken bar both ends of the surface to be measured, end face inner bore line angle can be measured, according to the lead of helix, angle principle, helical pitch can be calculated.
