Abstract
The utility model discloses a kind of dial gauge measuring device, including the dial gauge fixed block and dial gauge guide sleeve for positioning dial gauge body, the front end of dial gauge is equipped with dial indicator measuring head, its feature is that one end termination face that the dial indicator measuring head is contacted with unit under test is yi word pattern convex surface.
Description
Technical field
It the utility model is related to a kind of measuring apparatus, and in particular to a kind of dial gauge measuring device.
Background technology
Dial gauge measurement in Automobile Lamp Gauge measurement using increasingly extensive, since the dial indicator measuring head of first wife is small bulb,
Can be understood as a point, in the case that when measurand (be, for example, lens), area is larger, point contact planar survey without
It is suspected to be very accurate.Its instrumentation plan is as shown in Figure 1：Dial gauge 100 is through dial gauge fixed block 110 and dial gauge guide sleeve
120 positioning, the dial indicator measuring head 130 of its front end are used for measuring lens 210.
But during actual production and use, it is not that an area is very smooth that we, which have many measurement objects,
, the possible area very little in measured point, such as cambered surface and crest line, such case are also very common inside lamps.And existing hundred
If a point table gauge head measures this place, the small dimensional variations of measurand are the ripple that measuring point can be caused to occur by a relatively large margin
It is dynamic, further result in measurement distortion.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of to that can realize accurately measure hundred compared with small area
Divide table measuring device.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of dial gauge measuring device, including dial gauge fixed block and dial gauge for positioning dial gauge body are oriented to
Set, the front end of dial gauge are equipped with dial indicator measuring head, its feature is one end termination that the dial indicator measuring head is contacted with unit under test
Face is yi word pattern convex surface.
Further as the technical program is improved, and the trend and dial gauge watch face on the yi word pattern convex surface are perpendicular.
Further as the technical program is improved, and the dial gauge fixed block is equipped with guide groove, the dial gauge
Guide sleeve is equipped with and can insert in the shop bolt in the guide groove.
One of preferred embodiment as the utility model, the guide groove are bar-shaped trough, its slot bottom moves towards and described hundred
Divide the body of rod residing for table gauge head parallel.
Using the dial gauge measuring device of above-mentioned technical proposal, fast can accurately realize to cambered surface and crest line etc.
The measurement of smaller measuring point surface section.

Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Dial gauge measuring device as shown in Figures 2 and 3, dial gauge 300 are led by dial gauge fixed block 310 and dial gauge
It is fixed on to set 320 and dial gauge fixed thread 350 on dial gauge firm banking 340, the lower part of dial gauge 300 is dial gauge
Gauge head bar 300 its rod end be provided with a yi word pattern gauge head 331, the setting of the yi word pattern gauge head 331 primarily to
Measure insufficient and improved when solving smaller to measuring point area in the prior art, ball-type gauge head that will be original is changed to present
Manifold, concrete structure are the yi word pattern end face that termination face is arranged to protrusion.But be changed to after manifold, due to tested pair
As if crest line or circular arc, if gauge head direction of insertion is not right, still it is difficult to play expected effects.Still again fixed in dial gauge
Block 310 adds mistake proofing limiting slot (mistake proofing groove 311 i.e. in figure) above, on corresponding dial gauge measurement guide sleeve 320
Increase mistake proofing pin (the mistake proofing pin 321 in corresponding diagram), it is all desired angle and product (ginseng so to ensure that we are inserted into gauge head every time
See the lens 220 in figure) contact, referring specifically to shown in Fig. 2 and Fig. 3.
The mistake proofing groove 311 vertically set, its width match with mistake proofing pin 321, both spacing combinations, can be with
Realize after whole dial gauge is positioned, the trend of the yi word pattern end face of yi word pattern gauge head 331 can be kept and dial gauge watch face
It is perpendicular.
Claims (4)
