Abstract

The utility model discloses a vernier caliper which comprises a vernier of the vernier caliper, a scale, installation ends located on the vernier and the scale, a locking screw installed in the upper portion of the vernier and used for fixing the vernier, measuring pawls installed on the installation ends, and spherical probes, each of which is welded at the tail end of the lower portion of the corresponding measuring pawl. The lower end of one of the installation ends is provided with a groove used for movably installing one of the measuring pawls. According to the vernier caliper, the problem that wall thickness of a part with a multi-curved surface cavity cannot be measured through a general vernier caliper is solved, and the disadvantage that data cannot be read directly when an outside caliper is used to measure is also overcome. The vernier caliper is applicable to any measuring pawl, and limitation of a special tool for a special product is overcome.

Description

A kind of vernier caliper
Technical field
The utility model relates to a kind of measurer, and is particularly a kind of for the multi-functional vernier caliper of measuring housing shape product wall thickness.
Background technology
When housing shape product is carried out the measurement of wall thickness, traditional vernier caliper, often be subjected to the restriction of measuring claw shape, can't measure the housing product of die cavity complexity, simultaneously need repeatedly to measure during in the past vernier caliper measurement wall thickness, again the external diameter internal diameter is calculated and just can draw wall thickness, can't when measuring, directly read, increased error.
The utility model content
The purpose of this utility model is: the spheric probe of the utility model by being welded with different-diameter at measuring claw as with the contact component of product to be measured, can adorn product inside by stretching into, one end gauge head of measurer is stretched into part die cavity inside, another gauge head is taken and is bumped at the part outside surface, the swing measurer, read the minimum value of measurer correspondence, obtain the wall thickness of product.Solved traditional vernier caliper because the measuring claw shape problem of general vernier caliper can not be measured the difficult problem of many curved surfaces cavity part wall thickness, can not direct reading disadvantage when also having solved simultaneously the external callipers measurement.
The utility model is to realize by following method:
A kind of vernier caliper, comprise vernier caliper vernier 1, vernier lock-screw 2, scale 3, and the measuring junction part, it is characterized in that described scale 3 is provided with first measuring claw 6, described vernier 1 is provided with second measuring claw 7, and the bottom of described first measuring claw 6 and second measuring claw 7 is provided with a spheric probe 8; By installing spherical side head additional, because the contact area of spheroid is bigger, further improved the accuracy of measuring, reduced error, spheroid also makes things convenient for vernier caliper to slide at product to be measured simultaneously, thereby can find out thinnest part or thickness fast.
As further innovation of the present utility model, bottom and the upper end of described first measuring claw 6 and second measuring claw 7 have the certain deviation distance; Make the measurement of vernier caliper no longer be confined to only measure the surfacing object, can solve the shortcoming that common calliper can't be measured irregular product inner wall thickness like this, simultaneously also can once just measure wall thickness, not need to survey external diameter earlier and survey internal diameter again, save the time.By being set, different measuring claws can reach the purpose of surveying the products of different specifications wall thickness simultaneously.
As further innovation of the present utility model, also be provided with between described first measuring claw 6, second measuring claw 7 and the measuring junction between first installation end 4 and second installation end, 5, the first measuring claws 6, second measuring claw 7 and first installation end 4, second installation end 5 and connect by securing member.Can make measuring claw carry out at any time replacing according to different operating modes by this scheme, avoid the defective of the supporting specific purpose tool of specific component, reduce cost, also save the time.
As further improvement of the utility model, adopt screw, nut or rivet to connect between described first measuring claw 6, second measuring claw 7 and first installation end 4, second installation end 5; Can make replacing convenient like this, save cost.
As further improvement of the utility model, the described installation end bottom that is positioned at the vernier place has a mounting groove; Can allow measuring claw according to self suitable installation site of shape selection, make this measurer when changing difform measuring claw, can the slide calliper rule vernier be made zero because the radian of measuring claw is different.
The spheric probe of the utility model by being welded with different-diameter at measuring claw as with the contact component of product to be measured, can adorn product inside by stretching into, one end gauge head of measurer is stretched into part die cavity inside, another gauge head is taken and is bumped at the part outside surface, the swing measurer, read the minimum value of measurer correspondence, obtain the wall thickness of product.Solved traditional vernier caliper because the measuring claw shape problem of general vernier caliper can not be measured the difficult problem of many curved surfaces cavity part wall thickness, can not direct reading disadvantage when also having solved simultaneously the external callipers measurement.

Fig. 1 is the vernier caliper part drawing.
Fig. 2 is that vernier caliper uses synoptic diagram.
Fig. 3 is product cross section figure to be measured.
Description of reference numerals: 1, vernier caliper vernier, 2, the vernier lock-screw, 3, scale, 4, first installation end, 5, second installation end, 6, first measuring claw, 7, second measuring claw, 8, spheric probe, 9, mounting groove.
Embodiment
Be described further below in conjunction with accompanying drawing
As Fig. 1,2, the utility model shown in 3 is by the vernier caliper transformation of standard, comprise vernier caliper vernier 1, scale 3 is positioned at first installation end 4, second installation end 5 on vernier 1 and the scale 3, be installed in vernier top, be used for the fixedly lock-screw 2 of vernier, be installed in first measuring claw 6, second measuring claw 7 on the installation end, be welded in the spheric probe 8 of measuring claw lower end.By welding and the spheric probe 8 of measuring claw lower end, measure the irregular inner wall thickness of product to be measured, can prevent effectively that common vernier caliper from can only measure the limitation of smooth smooth internal face thickness.Also solved simultaneously common calliper when measuring, need repeatedly to measure obtain earlier outside through SR1, obtain internal diameter SR2 again, just can draw wall thickness δ.
First measuring claw 6 of this vernier caliper, second measuring claw 7 and first installation end 4, second installation end 5 adopt the locking type of screw-nut to be connected, and at different tube diameters and interior wall construction the time, can change different measuring claws and spheric probe.Save the resource consumption that welds again with special thing special use, also improved the applicability of this measurer.
