Abstract
The utility model discloses a surface difference measuring instrument. The surface difference measuring instrument comprises a supporting piece, and a dial indicator fixed on the supporting piece, wherein the supporting piece is parallel to a measuring rod on the dial indicator; and during zero adjustment, a measuring head at the lower end of the measuring rod of the dial indicator is on the same horizontal plane as the lower end of the supporting piece. Through arranging the supporting piece on the dial indicator and simultaneously arranging a spring on a clamping needle, the measuring instrument can perform an automatic resetting function, is simultaneously easy to manufacture, is convenient to carry, can conduct detection rapidly, conveniently and accurately, has a wide use range and improves the work efficiency.
Description
Technical field
The utility model relates to a kind of measuring instrument, relates in particular to a kind of measuring instrument of measuring stamping parts top mouth size and even surface face difference.
Background technology
Usually, need to debug after mould development comes out, debug the debugging part that is produced and all need on measuring instrument, check affirmation, qualified up to mould.The a collection of part that the qualified back of mould produces generally all needs to extract out 3 to 5 and detect definite qualification rate to measuring instrument.Certainly concrete sampling rate still needs to determine according to actual conditions, therefore needs a large amount of frequent measurements to guarantee the quality of part.
At present domestic mould factory of China and stamping parts manufacturing plant on detecting stamping parts level and smooth profile face difference and also using ruler, wedge chi during the mouth size of limit, exist the data of measuring accurate inadequately, metering system trouble and lose time and wait deficiency.For some complicated parts, there is very big difficulty during measurement especially, detection efficiency is very low for full-scale testing.Level and smooth profile of stamping parts and limit mouth tolerance are generally: ± 0.5mm and ± 1.0mm.
Stamping parts factory produces push rod that drawing die uses, and all need carry out one-shot measurement in every month, and such push rod has tens up to a hundred, and measure with height gauge all needs to adjust at every turn, and very trouble influences work efficiency.
Summary of the invention
The utility model provides a kind of face difference measurements instrument that can quick and convenient measurement, solved the problem of even surface and limit mouth dimensional measurement difficulty on the stamping parts.
A kind of difference measurements instrument comprises support member, is fixed on the clock gauge on the support member, and support member is parallel with the sounding rod on the clock gauge, and the measuring head of clock gauge sounding rod lower end and support member lower end are at same surface level during zeroing.
Described support member, the lower end is provided with standard, and standard and support member can be wholely set, and are convenient to processing, and both sides, standard lower end are provided with chamfering, can select down miter angle, conveniently some baroque parts are measured.
Measuring head is equipped with in the sounding rod lower end of described clock gauge, measuring head can the selection card pin, card pin and sounding rod flexibly connect, described moving connecting mechanism can be selected common detachable mechanism for use, for example can select threaded connection or engagement connection mechanism etc. for use, can be convenient for changing after the wearing and tearing of card pin; Sounding rod is provided with the sleeve of fixedlying connected with clock gauge table body in the upper end outward, can protect sounding rod, avoids sounding rod to be polluted, external force extruding etc.
Described card pin is coated with spring, and spring one end and sleeve lower end offset, and the other end offsets with the boss that blocks on the pin, can make the card pin return to null position after measuring; Spring is provided with the soft rubber shell outward, is used to protect spring to avoid being polluted, and guarantees accuracy of detection, increases the service life.
Described clock gauge can be selected clock gauge common on the market, and the concrete model of accuracy selection clock gauge is according to actual needs guaranteed the measuring accuracy of measuring instrument.Return to zero earlier before described difference measurements instrument uses, measuring head during zeroing on the clock gauge and standard lower end are at same surface level.
The utility model is set up a spring simultaneously by set up a support member on clock gauge on the card pin, make measuring instrument have automatically reset function, makes easily simultaneously, and is easy to carry, and it is quick and convenient accurate to detect, and usable range is wide, has improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model face difference measurements instrument;
Fig. 2 is the right TV structure synoptic diagram of face difference measurements instrument shown in Figure 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of difference measurements instrument comprises support member 5, is fixed on the clock gauge 1 on the support member 5, and support member 5 is parallel with the sounding rod 2 on the clock gauge 1, and the measuring head of clock gauge 1 sounding rod 2 lower ends and support member 5 lower ends are at same surface level during zeroing.
Measuring head is equipped with in sounding rod 2 lower ends of clock gauge 1, and measuring head is card pin 4, and card pin 4 is a high-abrasive material, and card pin 4 is fixedlyed connected with sounding rod 2 screw threads, when the card pin damages, can change fast.The sleeve 8 that body is fixedlyed connected is shown with clock gauge 1 in the sounding rod 2 outer upper ends that are provided with.
The spring 3 outer soft rubber shells that are provided with a protection spring 3.Clock gauge 1 is fixedlyed connected with support member 5 by the socket head cap screw 7 of M6 type, during damage parts, can change at any time.Support member 5 is the iron block of a rectangular parallelepiped.
The process of in the present embodiment cubing body limit mouth being measured is as follows:
At first before use clock gauge is returned to zero, select a level and smooth surface level, make standard 6 lower ends and 4 while of card pin exposure level face, revotating card pin 4 makes pointed zero graduation line.Need to determine the position of detection, standard 6 lower ends are near the cubing surface, and card pin 4 contacts with the limit mouth, and the numerical value on the clock gauge is exactly the vertical range of limit mouth to the cubing surface.
The process of in the present embodiment the employed push rod of production drawing die being measured is as follows:
Clock gauge 1 after the zeroing is fixed on the vernier of height gauge, measure the push rod height with height gauge, because after measuring, the card pin 4 of clock gauge 1 is got back to the zero reference position automatically, do not need again the vernier on the height gauge to be adjusted, so can directly measure, accelerate work efficiency to next push rod.
