Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, 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 an end of scale; Vernier is arranged on the scale, and slides at scale; Be provided with reading device on the scale: described adjustable stopple is placed in the measured circular hole, the center of circle of measured circular hole in adjustable stopple one fixedly on the straight line, the point that described fixedly straight line and scale intersect is the zero point of scale.
As shown in Figure 1, be the structural front view of mesopore of the present invention limit first embodiment of distance mearuring equipment.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, the large end of the first adjustable stopple 100 radiuses is connected with vernier 200, and the point that the straight line at the high place of cone and scale 300 intersect is the zero point of scale 300; Described vernier 200 is arranged on the scale 300, and slides at scale 300; Be provided with reading device on the scale 300.Because the radius of cone different cross section is different, this just can adapt to the measured circular hole of different radii, cone the first adjustable stopple 100 is placed in the measured circular hole, the planes overlapping at the cross section that radius equates with measured circle hole radius on the cone and measured circular hole place, the center of circle of measured circular hole is on the straight line at the high place of cone the first adjustable stopple 100, the zero point of scale 300 is also on the straight line at the high place of the adjustable stopple 100 of cone, therefore, the zero point of the center of circle of measured circular hole and scale 300 is on same straight line, like this, just can guarantee to align with the center of circle zero point, guarantee to measure accurately.
In order to make this limit, hole distance mearuring equipment be applicable to the measured circular hole of more different radiis, the described first adjustable stopple 100 is arranged to tape measure cone (being that cone can stretch) as tape measure, be provided with retractor device (not shown in FIG.) in the cone, the size of tape measure cone changes with the flexible of retractor device: the first adjustable stopple 100 is arranged to the tape measure cone, when retractor device extends, the tape measure cone stretches under the drive of retractor device, like this, the bottom surface radius of cone just can become greatly, to adapt to the larger measured circular hole of size; When needs were measured the small size circular hole, retractor device shortened, and the 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 of the present invention limit first embodiment of distance mearuring equipment.Reading device on the described scale 300 can be for being engraved in the scale 310 on the scale 300, like this, cone the first adjustable stopple 100 is placed in the measured circular hole, vernier 200 is stuck on a certain straight flange, the scale 310 that vernier 200 slips at scale 300 is the measured circular hole center of circle to the distance of straight flange, like this, just can accurately measure circular hole to the straight flange distance.
Reading device on the 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 the rotating disk, and counter is arranged on the rotating disk, and electronic display 321 is connected with counter; Rotating disk is connected with vernier 200, be connected by rope between rotating disk and the first adjustable stopple 100, the length of the length of described rope and scale 300 is suitable, the described rotating disk center of circle and the distance of scale between 300 zero points are preset value l, described preset value l and rotating disk radius r all are recorded in the counter: when not needing to find range, vernier 200 is near zero point, and rope is on rotating disk; When vernier 200 when scale 300 slides, rope on rotating disk is drawn out, 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)=the l(preset value)+2 π r*n(rotating disk radiuses) calculate circular hole to the straight flange distance, show in real time by electronic display 321.
As shown in Figure 3, be the structural front view of mesopore of the present invention limit another embodiment of distance mearuring equipment.If need to measure circular hole to the distance between the circular hole, determine because the circular hole center of circle is bad, can cause the error measured if directly vernier 200 is stuck in measurement in the circular hole, therefore, the second adjustable stopple 210 is set below described vernier 200 simultaneously, and the structure of the described second adjustable stopple 210 is consistent with the first adjustable stopple 100 structures described above.The first adjustable stopple 100 is placed in one of them circular hole, vernier 200 slides into another circular hole place at 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, thereby obtain the accurate distance between two circular holes.
In order to make this limit, hole distance mearuring equipment adapt to range observation between the how different circular holes (two measured circular holes at grade or two measured circular holes at grade or not), 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 the time, the first adjustable stopple 100 will guarantee sustained height (the first adjustable stopple 100 is bee-line with the distance that the identical plane of the second adjustable stopple 210 radiuses measures at the sustained height guarantee) with the identical plane of the second adjustable stopple 210 radiuses, at this moment, if the identical plane of two adjustable stopple radiuses is not at same plane, expansion link just can stretch, make the first adjustable stopple 100 plane identical with the second adjustable stopple 210 radiuses at sustained height, guarantee the accurate of measurement; When two measured circular holes not at grade the time, measure two circular holes apart from the time, will stretch expansion link (the flexible length of expansion link is the vertical range of two circular holes), make the second adjustable stopple 210 elongations, the second adjustable stopple 210 is positioned in the measured circular hole.
This limit, hole distance mearuring equipment is placed on adjustable stopple in the circular hole by adjustable stopple is set, and to determine zero point (being the circular hole center of circle), because the aperture of stopple is adjustable, therefore can adapt to the circular hole of different radii to the measurement of straight flange distance; Can also adjustable stopple also be set at the vernier place, like this, just can measure center to the distance between the center of circle; This limit, hole distance mearuring equipment is practical, measures accurately.
