Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
This limit, hole distance mearuring equipment comprises adjustable stopple, vernier and scale, and described adjustable stopple is arranged on one end of scale; Vernier is arranged on scale, and slides on scale; Scale is provided with reading device: described adjustable stopple is placed in measured circular hole, on the fixing straight line in adjustable stopple of the center of circle of measured circular hole, the described fixing straight line point crossing with scale is the zero point of scale.
As shown in Figure 1, be the structural front view of mesopore limit distance mearuring equipment of the present invention first embodiment.This limit, hole distance mearuring equipment comprises the first adjustable stopple 100, vernier 200 and scale 300, described adjustable stopple 100 is arranged to cone, one end that first adjustable stopple 100 radius is large is connected with vernier 200, and the straight line at the high place of the cone point crossing with scale 300 is the zero point of scale 300; Described vernier 200 is arranged on scale 300, and slides on scale 300; Scale 300 is provided with reading device.Radius because of cone different cross section is different, this just can adapt to the measured circular hole of different radii, adjustable for cone first stopple 100 is placed in measured circular hole, the planes overlapping at the cross section that on cone, radius is equal with measured circle hole radius and measured circular hole place, the center of circle of measured circular hole is on the straight line at the high place of the adjustable stopple of cone first 100, the zero point of scale 300 is also on the straight line at the high place of the adjustable stopple of cone 100, therefore, the center of circle of measured circular hole and the zero point of scale 300 are on the same line, like this, just can ensure that zero point aligns with the center of circle, guarantee the accurate of measurement.
In order to the measured circular hole making this limit, hole distance mearuring equipment be applicable to more different radiis, described first adjustable stopple 100 is arranged to tape measure cone (namely cone can stretch as tape measure), retractor device (not shown in FIG.) is provided with in cone, the size of tape measure cone changes with the flexible of retractor device: the first adjustable stopple 100 is arranged to tape measure cone, when retractor device extends, tape measure cone stretches under the drive of retractor device, like this, the bottom surface radius of cone just can become large, to adapt to the larger measured circular hole of size; When small size circular hole measured by needs, retractor device shortens, and tape measure cone is retracted, and the bottom surface radius of cone diminishes, to adapt to the smaller measured circular hole of size.
As shown in Figure 2, be the structure vertical view of mesopore limit distance mearuring equipment of the present invention first embodiment.Reading device on described scale 300 can for being engraved in the scale 310 on scale 300, like this, cone first is adjustable, and stopple 100 is placed in measured circular hole, vernier 200 is stuck on a certain straight flange, the scale 310 that vernier 200 slips on scale 300 is the distance of the measured circular hole center of circle to straight flange, like this, circular hole can just accurately be measured to straight flange distance.
Reading device on described scale 300 can also be electronical display reading device 320, and described electronical display reading device 320 comprises electronic display 321, rotating disk (not shown in FIG.) sum counter (not shown in FIG.); Described electronic display 321 is arranged on above rotating disk, and counter is arranged on rotating disk, and electronic display 321 is connected with counter; Rotating disk is connected with vernier 200, be connected by rope between rotating disk with the first adjustable stopple 100, the length of described rope and the length of scale 300 suitable, distance between the described rotating disk center of circle and scale 300 zero point is preset value l, described preset value l and rotating disk radius r are all recorded in counter: when not needing to find range, vernier 200 is near zero point, and rope is around on rotating disk; When vernier 200 slides on scale 300, be drawn out around the rope on rotating disk, rotating disk rotates corresponding number of turns n thereupon, the rolling counters forward number of turns, counter according to formula L(circular hole to straight flange distance)=l(preset value)+2 π r*n(rotating disk radiuses) calculate circular hole to straight flange distance, shown in real time by electronic display 321.
As shown in Figure 3, be the structural front view of mesopore limit of the present invention another embodiment of distance mearuring equipment.If need to measure the distance between circular hole to circular hole, determine because the circular hole center of circle is bad, if directly vernier 200 be stuck in measurement in circular hole can cause measure error, therefore, below described vernier 200, arrange the second adjustable stopple 210, the structure of described second adjustable stopple 210 is consistent with the described above first adjustable stopple 100 structure simultaneously.First adjustable stopple 100 is placed in one of them circular hole, vernier 200 slides into another circular hole place on scale 300, and the second adjustable stopple 210 is placed in another circular hole, like this, just can determine the center of circle of two tested circular holes, thus obtain the accurate distance between two circular holes.
Range observation between how different circular hole (two measured circular holes at grade or two measured circular holes at grade or not) is adapted in order to make this limit, hole distance mearuring equipment, also be provided with expansion link (not shown in FIG.) between described vernier and the second adjustable stopple 210: when two measured circular holes at grade time, the plane that first adjustable stopple 100 is identical with the second adjustable stopple 210 radius will ensure sustained height (distance that the plane that the first adjustable stopple 100 is identical with the second adjustable stopple 210 radius draws in the measurement of sustained height guarantee is bee-line), at this moment, if the identical plane of two adjustable stopple radiuses is not at same plane, just can stretch expansion link, make plane that the first adjustable stopple 100 is identical with the second adjustable stopple 210 radius at sustained height, ensure the accurate of measurement, when two measured circular holes not at grade time, when measuring the distance of two circular holes, expansion link will be stretched (vertical range that the length that expansion link stretches is two circular holes), the second adjustable stopple 210 is extended, the second adjustable stopple 210 is positioned in measured circular hole.
This limit, hole distance mearuring equipment, by arranging adjustable stopple, is placed on adjustable stopple in circular hole, to determine zero point (i.e. the circular hole center of circle), because the aperture of stopple is adjustable, therefore can adapt to the measurement of circular hole to straight flange distance of different radii; Adjustable stopple can also be also set at vernier place, like this, just can distance between measure center to the center of circle; This limit, hole distance mearuring equipment is practical, measures accurately.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
