Abstract

The rectangular measurement system as described above can measure rectangularity in precision and eventually raised reliance and quality of processed product. And also, since rectangular measurement/examination device with high accuracy can be provided regardless of place and time high cut of product cost in production line is expected and quick and accurate professional result will be created in technical and functional education field and finally with its broad possibility of exploitation to foreign market it can serve domestic industrial development too.

Description

SQUARENESS INSPECTION SY

BACKGROUND OF THE INVENTION

Field of the Invention:

This invention refers to Rectangularity Measurement System. In detail this invention refers to Close Measurement System which can measure rectangularity of perpendicular line up to 0.001 mm by standard cylinder rectangular ruler and magnification-amplification device.

Description of the Prior Art;

Generally, square master equipment is used to examine rectangularity measurement of exclusive laboratory. However it is recognized that this high-cost equipment cannot be ordinarily used in production field and one of the easiest ways of measuring it is using a square by contacting it perpendicular line of processed product (2) to measure amount of light passing from opposite side with eyes and this is very popularized condition. Square as standard, even though (+)(-) signals at the and of square height is logical right-angle measured by worker trusting the ruler 100 percent there were always reflection of error pointed out in rectangular accuracy of measured product. SUMMARY OF THE INVENTION

This invention was produced to recognized the rectangular measurement value into number even before measurement processing of processed product is completed and it helps inspector to quickly recognized by magnifying measured values 10 times no to created any recognition error. And for precise establishment of measurement location, pinion gear and rack gear device is equipped and for solidification of location measurer after location change completion suspension screw is equipped and with standard cylinder square (KS 1^st Level), zeroing location always can be fixed by inspector and worker.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will be described in detail by way of a preferred embodiment with reference to accompanying drawings.

This invention is suggested to solve those problems mentioned above and the objective is to examine and measure exact rectangularity in product line and actual training field and to provide highly credited rectangular measurement system by indicating measured value in number.

To accomplish the objective, this invention includes procedure zeroing the location of measurer (11) by forming accuracy of (2+200/L) by rapping standard cylinder rectangular ruler with precision processed procedure, precision assembling procedure of 2:1 magnification axis (22, 23) and 2.5: 1 magnification axis (21) of measured value magnification-amplification device part (7), procedure elaborately assembling up and down movement rotation axis and equipping rack gear (13) for smooth movement of up and down movement slider (9) and finally procedure zeroing back rash of measurer (11) mentioned above.

Detailed Description of Invention

Formation and description of enforcement example of invention to remove former defect and accomplish the objective are explained with attached figures as followed.

Figure 1 is perspective view showing method of measuring rectangularity and figure 2 is side view describing location and direction of square accuracy for rectangularity measurement. Figure 3 is front view showing zeroing of rectangularity measurement device and figure 4 is front of rectangularity examination/measurement condition of press metallic pattern assembly punch. Finally figure 5 is sectional view showing formation of core parts of lOtime-magnification amplification device part. In precision examination/measurement method for measuring processed/assembled rectangularity of metal and non-metal of this invention,

This invention contains procedure magnifying magnification axis and measurer into (1: 1), (2: 1), (5:1) and (10: 1) with 3 level series assembly, procedure fixing the location and zeroing suspension part with cylinder square as standard device, procedure equipping cylinder sleeve which dial gauge fixation type magnification/amplification device part and up/down movement slider of measurer can be fixed combined, procedure dial gauge and magnification/amplification device part equips rack gear on standard support pole for easy up/down movement of measure and assembling and equipping pinion gear axis to up/down slide movement body of measurer and procedure equipping graduation ruler to pole for quick recognition of movement height.

In figure 5, when magnification axis (21) of 2.4:1 measured values sensed with measurer (11) is pushed back round figure of measurer (11) slides on 2.5:1 magnification axis (21) slope and eventually moves back. At this point, effective distance is 2.5:. The formula is (tan26°48'5.07" =0.4)= 1 _ 0.4=2. And when 2.5: 1 magnification axis (21) ascends in rear direction, it pushes 2: 1 magnification axis (22) slope. In this case too, when 2.5: 1 magnification axis (21) has effective distance of 1, 2:1 magnification axis (22) moves about value of 2. The formula in this case is (tan26°33'54.18"=0.5)=1 D 0.5=2. And when 2:1 magnification axis (22) moves back and pushes 2L1 magnification axis (23) the formula is materialized and so since total value of magnification is (2.5x2x2=10), 10 time amplification device is formed. And then dial gauge(14) is assembled and fixed on where it touches rear flat part of 2: 1 magnification axis (23). And then measurer support sleeve (24) is inserted into up/down movement slider (9) and by fixing measured location into demanded rectangular measurement location by rotating rotation axis of up/down movement gear as shown in figure 4 and holds it tight with stop screw. And after fixing zeroing suspension part (12) on adequate location, cylinder square (6) is slowly pushed to zeroing suspension part (12) till it touches each other and then the measurer (11) moves back and indication need of dial gauge (14) moves.

At this point, figure board of dial gauge (14) is rotated to be fixed on 0 and it operates as shown in figure 4. When measurement operation is operated with formation condition mentioned above, when real measurement sensible amount is 0.01 mm, indication needle of dial gauge (14) stops on 10 graduation point. In this case it should not be recognized as 0.1mm but 10 sections of 0.01mm. Operational Examples

With this invention recognition of graduation is much easier since the value is indicated with analogue graduation or digital digits so that the value of rectangularity can be measured objectively and it will save time measurement/examination time and operation time.

This present invention is not limited on certain operation example but can be developed and changed by any person with technical knowledge this invention belongs within range of invention objective.
