Abstract
The invention relates to a geometric tolerance measuring device of a mechanical part, in particular to a circumscribed triangle type concentricity measuring apparatus. The concentricity measuring apparatus comprises a rotating shaft, a limit head plate, a limit middle plate, a limit tail plate, a sliding groove, a dial indicator, a positioning bolt, positioning screw caps, a measuring rod and a positioning groove, wherein the limit head plate is provided with the transverse sliding groove, and the measuring rod with threads is positioned in the sliding groove; the two positioning screw caps are sleeved on the measuring rod and positioned at both sides of the limit head plate; the limit tail plate is provided with the positioning groove; the end part of the limit heat plate extends out of the positioning groove; the limit tail plate at the top end of the positioning groove is provided with a screw hole; and the positioning bolt is positioned in the screw hole. Under the condition that a workpiece to be measured is maintained still, the coaxiality of the workpiece can be measured, thus the invention is particularly suitable for large workpieces which are inconvenient to move.
Description
Technical field
The present invention relates to a kind of mechanical component form and position tolerance measurement mechanism, particularly relate to a kind of Circumscribed triangle type coaxial measuring apparatus.
Background technology
Large-scale workpiece is because volume is big, Heavy Weight, be difficult to rotate the right alignment of measuring its endoporus and cylindrical as dead axle as the such clamping of part on chuck, the patent No. is that 200820040324.8 " measuring apparatus for coaxiality of large workpiece " discloses the coaxality measuring mechanism that a kind of support is provided with two rotation axiss that rotor wheel is housed.Because this technical scheme still requires workpiece is moved to ability energy measurement on its support, therefore can not fundamentally reach the effect that " exempting to move " measures.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provide a kind of at large-scale workpiece, need not the Circumscribed triangle type coaxial measuring apparatus that travelling workpiece just can carry out coaxality measurement.
The scheme that solves the technology of the present invention problem is: Circumscribed triangle type coaxial measuring apparatus is made of rotating shaft, spacing first plate, spacing middle plate, spacing tailgate, chute, dial gauge, bolt, positioning screw cap, sounding rod and locating slot.Spacing first plate, spacing in plate, spacing tailgate be the rectangular steel plates of rigidity, spacing first plate and spacing between the plate and spacing tailgate and spacing in all connect between the plate and all be in active relationship with rotating shaft by rotating shaft.A horizontal chute is arranged on the spacing first plate, and the sounding rod with screw thread is in the chute, and two positioning screw caps are placed on the sounding rod and are in the both sides of spacing first plate.The outer end of sounding rod is a dial gauge.Have locating slot on the spacing tailgate, stretch out from locating slot the end of spacing first plate.Have a screw on the spacing tailgate on locating slot top, bolt is in the described screw.
During measurement, make spacing first plate, spacing middle plate, spacing tailgate surround the triangular prism that xsect is the circumscribed triangle of workpiece for measurement, and the relative position relation of these three blocks of plates be fixed by bolt.The position of traverse measurement bar in chute is also fixing with the position relation of sounding rod and chute by two positioning screw caps.The triangular prism that surrounds is rotated around workpiece for measurement, sounding rod is promptly started working again.
Adopt such scheme, can reach following effect:
Because the present invention can keep the right alignment of measuring workpieces under the motionless situation at workpiece for measurement, for the large-scale workpiece that moves inconvenience, measure very convenient, improved efficiency of measurement.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Circumscribed triangle type coaxial measuring apparatus is made of rotating shaft 1, spacing first plate 2, spacing middle plate 3, spacing tailgate 4, chute 5, dial gauge 6, bolt 7, positioning screw cap 8, sounding rod 9 and locating slot 10.Spacing first plate 2, spacing in plate 3, spacing tailgate 4 be the rectangular steel plates of rigidity, spacing first plate 2 and spacing between the plate 3 and spacing tailgate 4 and spacing in all connect between the plate 3 and all be in active relationship with rotating shaft 1 by rotating shaft 1.A horizontal chute 5 is arranged on the spacing first plate 2, and the sounding rod 9 with screw thread is in the chute 5, and two positioning screw caps 8 are placed on the sounding rod 9 and are in the both sides of spacing first plate 2.The outer end of sounding rod 9 is dial gauges 6.Have locating slot 10 on the spacing tailgate 4, stretch out from locating slot 10 end of spacing first plate 2.Have a screw on the spacing tailgate 4 on locating slot 10 tops, bolt 7 is in the described screw.
During measurement, make spacing first plate 2, spacing middle plate 3, spacing tailgate 4 surround the triangular prism that xsect is the circumscribed triangle of workpiece for measurement, and the relative position relation of these three blocks of plates be fixed by bolt 7.The position of traverse measurement bar 9 in chute 5 is also fixing with the position relation of sounding rod 9 and chute 5 by two positioning screw caps 8.The triangular prism that surrounds is rotated around workpiece for measurement, sounding rod 9 is promptly started working again.
