Abstract

PROBLEM TO BE SOLVED: To prevent deterioration of size measurement precision by guiding a work size measuring rod with a guide bush, elevating the work size measuring rod with a cylinder for elevation, and measuring the elevated height with a digital gauge. SOLUTION: A work 1 is set on four reception points of a size measuring jig including standard reception points 2a, 2b of the work in the Z direction and positioned. Compressed air at a prescribed pressure is introduced into the inside of a cylinder 4a-3 for elevation from a nipple 4a-4 of a cylinder for elevating a rod for measuring the work size in the Z-direction. A measuring rod 4a-1 is guided by a guide bush 4a-2 for the measuring rod and the work 1 and the measuring rod 4a-1 are elevated at a preset speed proper to prevent wear and damage and the measuring rod is brought into contact with the parts for measuring the size of the work 1 in the Z-direction. The size of the work 1 in the Z direction can be measured from the elevated height of a probe 4a-5a of a digital gauge 4a-5 moved interlockingly with the measuring rod 4a 1. Difference of measured size and deterioration of size measuring precision can be prevented by the method.

2. Description of the Related Art For example, products such as television frames are required to have strict dimensional standards and no scratches. In a measuring device for measuring each standard dimension of a conventionally used television frame (hereinafter referred to as a work), a device for measuring a height in a Z direction is a device in which a Z direction dimension measuring rod is moved upward by a force of a compression spring. The work is always lifted, and then the work is set on both sides of the measuring jig with two hands. At this time, the Z-direction dimension measuring rod is pushed down from the upper surface of the rod by the weight of the work. The lower surface of the pushed-down Z-direction dimension measuring rod was measured for drop by a commercially available digital gauge to measure the dimension.

Actually, the work was set on the measuring jig with both hands, and a numerical deviation was tested. As a result, a maximum deviation of 0.01 mm was confirmed in 5 out of 100 measurements.
In addition, when the workpiece to be set is positioned in the left-right direction, the contact portion of the Z-direction dimension measuring rod upper surface is deteriorated in dimension measurement accuracy due to wear during repeated measurement,
Further, at the time of position adjustment, the work may be scratched due to the contact between the measuring rod and the Z-direction dimension measuring portion of the work,
A contact error of the work Z-direction measuring rod occurs due to a decrease in compression pressure of the compression spring, and there is a problem in dimension measurement accuracy at the time of repeated dimension measurement.
