Abstract
Description
The present invention relates to a perpendicularity measuring apparatus, and more particularly, to a perpendicularity measuring apparatus for measuring a rectangular angle of an object such as a ball guide post of a metal mold or various workpieces in a short time locally and locally.
BACKGROUND ART In a modern industrial society, mass production systems based on industrialization are becoming common, and there is a demand for importance on precision, performance and quality required for molds, various machines or workpieces. This requirement is difficult to ensure the functionality and compatibility of parts unless the designer, manufacturer, co-ordinator, and inspector in the field observe them organically and uniformly. Accordingly, the geometric dimension tolerance is applied in addition to the usual dimensional tolerance in the step of designing the parts of the metal mold or various mechanical devices or the workpiece.
In particular, the geometric dimensional tolerance is divided into shape tolerance and phase tolerance, and one of the shape tolerances is the right angle. Such a perpendicularity is defined as the extent to which the surface, axis or median plane of the regulating shape, relative to the datum, deviates from the complete orthogonal angle with respect to 90 degrees. If the precision of a die or a machine is greater than the prescribed tolerance, the deterioration of the function or the loss of compatibility leads to a loss of compatibility. Therefore, it is required to speed up the measurement enough to carry out the complete inspection of the manufactured parts.
An example of an object for measuring the perpendicularity is an upper / lower holder ball guide post of a mold. The ball guide post plays the most important role in positioning accuracy between the upper mold and the lower mold when assembling the mold. The guide rod that regulates the upper and lower holder movements of the upper and lower molds ensures the mold alignment and clearance of the mold .
Conventionally, in the case of a large mold, it is common to measure the perpendicularity of a ball guide post with a ball guide post assembled using a three-dimensional measuring machine. An example of such a three-dimensional perpendicularity measuring instrument is known in Patent Document 1 of the following prior art document. The first and second probe heads are installed on one end of the main body and are horizontally moved to inspect the two-dimensional perpendicularity of the object. Dimensional perpendicularity of the object is measured at one time by arranging the two perpendicularity measuring devices including the air supply part for supplying the air so as to horizontally move the object to 90 占 with respect to the central axis line of the object. However, it has been pointed out that such a conventional three-dimensional rectangular angle measuring instrument is not only inefficient in terms of cost and time, but also is difficult to measure since the probe head is horizontally moved by air supply to measure the perpendicular angle.
In the conventional three-dimensional rectangular measuring apparatus as disclosed in Patent Document 1, since the angle of the probe head is horizontally moved by the air supply to measure the perpendicular angle, it is not only inefficient in terms of cost and time, .
The present invention has been developed in order to overcome such conventional problems, and it is an object of the present invention to provide an apparatus and a method for measuring a perpendicularity of an object, An object of the present invention is to provide a perpendicularity measuring apparatus.
According to an aspect of the present invention, there is provided a measurement apparatus for measuring a measurement object, comprising: a horizontal base portion that is seated on a measurement position on which a measurement object is placed; and a tip portion on one side of the object to be measured from the base portion, A gauge post provided vertically upward on the base portion and having a plurality of horizontal insertion holes formed at regular intervals at upper and lower portions thereof, and a gauge post coupled to the horizontal insertion hole of the gauge post to define a zero point setting portion A rectangular angle including a dial gauge which can be converted to a rectangular angle by measuring the inclination of a rectangular measurement object in comparison with a zero point set by a zero setting unit while being closely attached to one side of the measurement object on the same vertical line as the tip of the measurement object A measuring device is provided.
In the present invention, the gauge post may be provided with a vertical gauge fixing hole formed vertically in the vertical direction and inserted into the vertical insertion hole to fix the dial gauge coupled to the horizontal insertion hole.
The dial gauge fixture is provided with a plurality of fixing holes aligned with the horizontal insertion holes of the gauge post at regular intervals in the up and down direction and the dial gauge fixture is coupled to the fixing hole of the dial gauge fixture in a state where the dial gauge fixture is inserted into the vertical insertion hole of the gauge post And a fixing pin for fixing the dial gauge fixing member may be provided.
The present invention configured as described above has the following effects.
First, the present invention has an effect that it is possible to measure the perpendicularity of a rectangular measurement object easily, quickly, and precisely by using a zero point setting unit and a dial gauge.
Secondly, the present invention has a low cost for constituting parts and can shorten the time required for carrying out the measurement of the perpendicular angle, and it is also possible for anyone to perform the measurement of the perpendicularity even if it is not an expert.
Third, the present invention is capable of direct measurement of squareness based on the numerical value measured by the dial gauge, conversion of angle is possible, and measurement accuracy is high because measurement error and deviation are small.
Fourthly, since the insertion position of the dial gauge can be variously changed with respect to the gauge post, it is possible to locally and easily measure only the portion required to measure the rectangular angle, and the efficiency of the operation is high.
Fifth, when the present invention is applied to the measurement of the right angle of the ball guide post of the mold, it is possible to precisely determine the correctness of the right angle, so that the effect of improving the quality of the mold and shortening the assembly time can be expected.
