The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of tooth plate radius of addendum pick-up unit; Comprise worktable, be arranged on worktable one end stationary installation, be arranged on the worktable other end and include the measurement mechanism of gauge head and be arranged on the worktable between stationary installation and measurement mechanism and include the locating device of calibrated bolck; It is characterized in that: described calibrated bolck side is an arc surface, and said gauge head one end is the plane and is that face contacts with the calibrated bolck side.
The utility model is creatively to have solved:
1. zero setting difficult problem: directly the surface of contact of calibrated bolck and gauge head is made arc surface, the radial distance of each point equates to cut and equals the arc surface radius like this, at an arbitrary position can be to cubing zero setting; It is simple to make arc surface processing, and dimensional accuracy reaches 1/10 of measured size tolerance easily, and processing and cost of upkeep are low.
2. gauge head gets into problem between two teeth: gauge head and measured circular arc surface of contact are made the plane, and width is slightly larger than two tooth point circle chordal thicknesss.It is tangent with tested tooth top all the time to guarantee that gauge head is measured face, can accurately measure tested tooth top with respect to the side-play amount of calibrated bolck circular arc in radial direction.Can accurately measure the radius of addendum of tested tooth plate accurately under the situation at the calibrated bolck radius.
At above-mentioned a kind of tooth plate radius of addendum pick-up unit; Said stationary installation comprises the quick folder that is arranged on worktable one end; And the register pin that matches with quick folder, said calibrated bolck one end is set in register pin and through quick folder this calibrated bolck is fixed on the register pin.
At above-mentioned a kind of tooth plate radius of addendum pick-up unit, said measurement mechanism comprises a sounding rod that is fixed on the worktable other end, and said sounding rod one end is fixed with digital display centimeter, and said gauge head is fixed on the sounding rod other end; Be provided with the spring that is set on the sounding rod between said gauge head and the digital display centimeter.
At above-mentioned a kind of tooth plate radius of addendum pick-up unit, said gauge head is the two tooth point circle chordal thicknesss of an end width on plane greater than tested tooth plate.
Therefore, the utlity model has following advantage:
1. can reach 1/10 of measured size tolerance easily to cubing zero setting at an arbitrary position, processing and cost of upkeep are low;
2. tested tooth top can be accurately measured with respect to the side-play amount of calibrated bolck circular arc, and the radius of addendum of tested tooth plate can be accurately measured accurately under the situation at the calibrated bolck radius in radial direction.
