Benefits of technology

The present patent relates to a measurement device for measuring the distance between a center of a through hole in an article and a side of the article. The device includes a positioning member, a support member, a measurement member, an elastic element, and a fixing member. The device is designed to improve accuracy and reliability in measuring the distance between the center of a through hole and the side of the article. The technical effects of the invention include improved accuracy and reliability in measuring the distance between the center of a through hole and the side of the article, as well as simplified and more efficient assembly of the measurement device.

Problems solved by technology

However, due to the complicated operation of the caliper and intrinsic fallibility thereof, measurement precision is lowered.

first embodiment

[0017]FIG. 5 is a second exemplary embodiment of a measurement device 8, differing from the first embodiment in that a positioning member 80 and a support member 30 are integrally formed, and the positioning member 80 extends vertically from an end of the support member 30.

second embodiment

[0018]FIG. 6 is a third exemplary embodiment of a measurement device 9, differing from the second embodiment in that a positioning member 902 two cylinders extending vertically from an end of a support member 30.

[0019]Referring again to FIG. 1, in other embodiments, measurement of the distance between the center of the through hole 102 and the side 104 can also be achieved by measuring a distance between the center of the through hole 102 and a side 106 opposite to the side 104, and the positioning members 20, 80 and 902 can be omitted. A distance between the center of the lower portion 405 and the side surface 306 is set to equal a normal distance between the center of the through hole 102 and the side 106. For example, if the diameter “d” of the through hole 102 is about 6 mm, the normal distance “L” between the center of the through hole 102 and the side 104 is about 20 mm, the thickness between the side 104 and the side 106 is about 5 mm, the normal distance “L1” between the cen...

Abstract

A measurement device for measuring a distance between a center of a through hole defined in a panel and a side of the panel extending from an end of the panel includes a positioning member, a support member, and a measurement member. The positioning member and the measurement member are set on two ends of the support member. An inside surface of the positioning member resists the side of the panel. A distance between the inside surface and a center of the measurement member is about equal to a normal distance between the side and the center of the through hole. If an actual distance between the side and the center of the through hole meets a determined specification, the measurement member will enter into the through hole.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to measurement devices, and particularly to a measurement device measuring a distance between a center of a through hole defined in an article and a side of the article.[0003]2. Description of Related Art[0004]In device machining, a punching or bending mode is frequently used. Often, the devices form curved panels, many parts of which can define multiple through holes. To ensure the distance between a center of a through hole defined in a panel and a side of the panel meets determined specifications, a caliper is frequently used. However, due to the complicated operation of the caliper and intrinsic fallibility thereof, measurement precision is lowered.BRIEF DESCRIPTION OF THE DRAWINGS[0005]FIG. 1 is an exploded, isometric view of a first exemplary embodiment of a measurement device, together with an article.[0006]FIG. 2 is an assembled, isometric view of the measurement device and the article of FIG. 1.[0007]FIG...
