Abstract

The utility model relates to a measuring instrument capable of measuring the dimension of the intersecting point of slant faces and capable of reading the measuring result visually. The utility model is composed of a rectangle ruler, a slide block, a contacting round ball, a central axis, a dial gauge, a measuring bracket, etc.

Description

Measure readout instrument directly perceived indirectly

The utility model belongs to mechanical measuring device, particularly a kind of measurement part inclined-plane intersecting point dimension, and can directly read the measurement mechanism of measurement result.

The method of existing measurement inclined-plane intersecting point dimension is: after treating the inclined-plane completion of processing of mechanical part, normally measure the size of intersection point with universal tool-measuring microscope, whether the inclined-plane that is processed with check puts in place.This measuring method is more time-consuming.If processing parts is many, also to wait.In addition, if intersection point is when coming transition with the garden arc, measures in this way and just seem more complicated.

The purpose of this utility model be to provide a kind of simple to operate, can measure the inclined-plane intersecting point dimension indirectly, and can read the measurement mechanism of measurement result intuitively.

In order to realize above-mentioned purpose, the solution that the utility model adopts is: the indirect measurement readout instrument directly perceived that is provided is made up of six parts such as try square, slide block, garden ball, axle, clock gauge and measurement bracket.In use, calculate respective heights BD in the following schematic diagram according to drawing earlier, then try square is placed on the platform, adjust the slide block height, the reading when making garden ball peace interstation distance equal BD on the clock gauge is zero.The perpendicular end surface of the part processed is leaned against on the upright arm of try square, and the garden ball of allowing is pressed on the inclined-plane that this part processes.Whether the size of being judged intersection point by the reading on the clock gauge meets the requirements.

The utility model has the advantages that simple in structurely, easy to operate, reading is directly perceived, but also saves time.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the structural drawing of an embodiment.

According to principle shown in Figure 1, calculate the height of slip gauge earlier.In Fig. 1, W is the part of processing, and bevel angle β to be processed and intersection height AB are known according to the processing drawing, thus θ=(90-β)/2, AC=R/tg θ, AD=AC-CD=(R/tg θ)-R=R (1-tg θ)/tg, BD=AB+AD.In Fig. 2, this indirectly measure readout instrument directly perceived by the try square (1) of band dovetail groove, band stationary installation, and can be on try square (1) dovetail groove movable slide block (2) and try square, garden that contact, known radius R, part inclined-plane ball (3), the axle (4) that contacts with clock gauge when measuring, clock gauge (5) and adorn measurement bracket six parts such as (6) that clock gauge uses and form.During use, the first height of using the slip gauge that highly equals above-mentioned BD to adjust try square (1) top shoe (2), and the position of the last clock gauge (5) of measurement bracket (6) are when making the peaceful interstation distance of garden ball (3) equal BD, axle (4) and clock gauge (5) contact, and allow the clock gauge reading be zero.When measuring, allow the part perpendicular end surface near the upright arm of the try square (1) of indirect measurement readout instrument directly perceived, garden ball (3) is pressed on the inclined-plane that part processes, and reads the numerical value shown in the clock gauge (5).If reading is zero, then intersection height meets the drawing requirement, and promptly Jia Gong inclined-plane puts in place.If reading is greater than or less than zero, then intersection height is greater than or less than the given size on the drawing, that is to say, the inclined-plane that is processed does not put in place.

Claims

1, a kind of indirect measurement readout instrument directly perceived, it is characterized in that by try square, band stationary installation and can be on try square movable slide block and the contacted garden of try square and part inclined-plane ball, when measuring and the contacted axle of clock gauge, clock gauge and fixedly the measurement bracket used of clock gauge form.
