Problems solved by technology

The existing circular runout inspection tool adopts a rotating shaft to cooperate with a lever. One end of the lever abuts against the inner wall of the workpiece to be measured, and the other end measures its swing value through a meter. In order to make the lever rotate freely, there is usually a gap between the rotating shaft and the lever Due to clearance fit, during the rotation detection process of the gage, the lever is subjected to the force of the inner wall of the workpiece to be measured, which causes the lever to swing in the axis direction of the rotating shaft, resulting in a large measurement error

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0020] Such as Figure 1 to Figure 3 As shown, a checker for inner circle runout includes a rotating base 1, a lever 5, a gauge 7 and an anti-backlash mechanism. The rotating base 1 is a cylindrical structure, and the outer wall of the rotating base 1 is provided with a Groove 1a, a lever seat 3 is fixed on the upper end surface of the rotating seat 1, and a through hole 3a is opened in the said lever seat 3, and the middle part of the lever 5 is installed in the through hole 3a through the rotating shaft 4, and the lever The lower end of the lever 5 extends into the through groove 1a, the lower end of the lever 5 is fixed with a ball contact block 6, the upper end of the lever 5 is fixed with an abutment block 8, and one side of the lever seat 3 is fixed with a table seat 2 ...

Abstract

The invention relates to an inner circle run-out testing fixture, which comprises a rotating seat, a lever, a meter and an anti-backlash mechanism. A lever seat is fixed on the upper end surface of the rotating seat, the middle part of the lever is rotationally arranged in a through hole through the rotating shaft, and a tension spring is arranged between a meter seat and the lever. The anti-backlash mechanism comprises a taper sleeve, balls and a pre-tightening adjusting sleeve. Concave conical surfaces are arranged at the two ends of the taper sleeve, and the taper sleeve is arranged betweenthe rotating shaft and the lever. The plurality of balls are respectively arranged in the conical surfaces at the two ends of the taper sleeve. A shaft shoulder abuts against the balls in the conicalsurface at one end of the taper sleeve. The rotating shaft is sleeved with the pre-tightening adjusting sleeve, and one end of the pre-tightening adjusting sleeve abuts against the balls in the conical surface at the other end of the taper sleeve. A gasket sleeves the rotating shaft, abuts against the other end of the pre-tightening adjusting sleeve and is locked through a nut. The gap between the lever and the rotating shaft is eliminated through the ball and the taper sleeve, so that the lever can bear large force in the axis direction of the rotating shaft, the lever cannot swing in the axis direction of the rotating shaft, and the measurement stability is high.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to an inner circle runout inspection tool. Background technique [0002] Circle run-out refers to the difference between the maximum and minimum readings measured by a fixed-position indicator in a given direction when the measured workpiece rotates around the reference axis for one revolution. [0003] In the production process of parts, the circular runout value is often detected. The existing circular runout inspection tool adopts a rotating shaft to cooperate with a lever. One end of the lever abuts against the inner wall of the workpiece to be measured, and the other end measures its swing value through a meter. In order to make the lever rotate freely, there is usually a gap between the rotating shaft and the lever Due to clearance fit, during the rotation detection process of the gage, the lever is subjected to the force of the inner wall of the workpiece to be meas...
