Abstract
A flatness and roundness detection tool comprises a base, wherein a vertical pushing air cylinder is arranged in the center of the base, a cylindrical threaded pipe is arranged on the upper surface of the base with the vertical pushing air cylinder as the center, a disc-shaped jack catch is installed on the cylindrical threaded pipe rotationally, and a workpiece support is arranged at the top end of the vertical pushing air cylinder; the disc-shaped jack catch comprises a connecting part and a detecting part, one end of the connecting part is connected with the cylindrical threaded pipe, the other end of the connecting part is connected with the detecting part through a hinge, the detecting part is perpendicular to the upper surface of the base, a detection needle is arranged at the upper end of the detecting part, a mobile groove is formed in the upper surface of the connecting part, and a long detecting rod parallel with the upper surface of the base is arranged in the mobile groove. The flatness and roundness detection tool can simultaneously detect flatness and roundness, shortens the time needed by detection, does not determine the circle center in advance when detecting roundness, and is practical to some extent.
Description
Technical field
The present invention relates to and detect frock accessory field, point out a kind of flatness and circularity testing tool especially.
Background technology
The detection of flatness and circularity is in processing, the status that occupation ratio is more important, it is an important indicator of inspection product acceptance criteria, in existing testing tool, the detection of flatness and the detection of circularity are separate independent detection mostly, which increase the time detecting cost, and existing roundness measurement instrument needs the home position first determining workpiece just can proceed roundness measurement mostly simultaneously, add operation, operate also cumbersome.
Summary of the invention
The object of this invention is to provide a kind of flatness and roundness measurement instrument, the detection of flatness and circularity can be carried out simultaneously, shorten the time required for detection, simultaneously when detecting circularity, not needing the determination carrying out the center of circle in advance, there is certain practicality.
The technical scheme realizing the object of the invention is as follows:
Flatness and circularity testing tool, comprise base, described base center is provided with and vertically promotes cylinder, described base upper surface, vertically to promote to be provided with cylindrical thread pipe centered by cylinder, described cylindrical thread pipe is rotatably installed with discoid claw, described vertical promotion cylinder top is provided with workpiece bracket, described discoid claw comprises connecting portion and test section, described connecting portion one end is connected with cylindrical thread pipe, the other end is connected through the hinge test section, described test section is vertical with base upper surface, the upper end of test section is provided with detection pin, the upper surface of described connecting portion is provided with shifting chute, the stock test rod parallel with base upper surface is provided with in described shifting chute.
Further, described workpiece bracket is provided with plane bearing with vertical promotion between cylinder top.
Further, described stock test rod centre position is provided with detection table.
After adopting said structure, the invention has the beneficial effects as follows: described roundness measurement is tested by discoid claw, described flatness is tested by stock test rod, roundness measurement is detected by the side-play amount of the test section of discoid claw, only need the side-play amount on two test sections in left and right equal, can test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Flatness and circularity testing tool, comprise base 1, described base 1 center is provided with vertical promotion cylinder 2, described base 1 upper surface, vertically to promote to be provided with cylindrical thread pipe 3 centered by cylinder 2, described cylindrical thread pipe 3 is rotatably installed with discoid claw 4, described vertical promotion cylinder 2 top is provided with workpiece bracket 5, described discoid claw 4 comprises connecting portion and test section, described connecting portion one end is connected with cylindrical thread pipe, the other end connects test section by hinge 6, described test section is vertical with base upper surface, the upper end of test section is provided with detects pin 7, the upper surface of described connecting portion is provided with shifting chute 8, the stock test rod 9 parallel with base 1 upper surface is provided with in described shifting chute 8.
Described workpiece bracket 5 is provided with plane bearing 10 with vertical promotion between cylinder 2 top, and described stock test rod 9 centre position is provided with detection table 11.
Specific description use procedure, flatness is detected, workpiece for measurement is placed on workpiece bracket, discoid claw described in rotation, discoid claw moves up and down on described cylindrical thread pipe, when the top of described stock test rod props up the surface of workpiece, described workpiece to be detected is rotated, when described surface of the work out-of-flatness to be detected, display is beated by the detection table on described stock test rod, described stock test rod can move in shifting chute, to facilitate the flatness detecting each position of workpiece;
For roundness measurement, when workpiece to be detected is positioned at after on workpiece bracket, the test section of the discoid claw described in adjustment, the thimble on test section is made to prop up the circumferential surface of workpiece for measurement, rotate workpiece for measurement, observe the drift condition detecting pin, when the detection pin side-play amount on two test sections is identical and offset direction is contrary, then show that workpiece for measurement has good circularity, otherwise then represent that circularity is not high.
Claims (3)
