Abstract
The utility model belongs to a displacement measuring instrument, relating to a universal lever centigrade meter. The utility model comprises a meter body, a dial, a meter pointer and a measuring head, and a shaft of the meter pointer is connected with a measuring lever by a rack mechanism; the head of the meter body is a cylinder, the rest part of the meter body is a cone, the dial is perpendicular to the axial line of the meter body, the head of the meter body is also provided with an elastic jacket which rotates relatively to the meter body, and the elastic jacket is connected with a connecting rod by a universal joint. Therefore, the meter body can rotate in any direction in space relatively to the connecting rod, and the measuring head can be made conveniently to contact the ground as long as the utility model is fixed and adjacent to a detected object.
Description
The utility model relates to a kind of displacement measurement instrument, specifically a kind of universal lever indicator.
Dial gauge is mainly used in measures inner concave and the inner hole surface displacement with respect to benchmark.Existing lever indicator mainly is made up of table body, dial plate, indicator, lever measuring head and rack and pinion drive mechanism.Because its table body is rectangle, dial plate is positioned at the side of table body again, and the back-moving spring of indicator axle is the spirality clockwork spring, so volume is bigger, it is very limited that measuring head gos deep into the degree of depth of endoporus.Particularly when the aperture hour, measuring head can only with the edge contact in hole, can't reach the purpose of centering.In addition, because its dial plate is positioned at the table body side surface, effective scope of activities of measuring head is very limited, therefore, in many cases in order to make measuring head can touch tested surface traverse measurement frame repeatedly, sometimes even be difficult to use, brings inconvenience to surveying work.
The purpose of this utility model is that existing lever indicator is improved, and the universal lever indicator that a kind of measuring head scope of activities is big, use occasion is wide is provided.
The solution that realizes the utility model purpose is: the lever indicator that is provided comprises table body, dial plate, indicator and is positioned at the measuring head of table end of body, wherein is connected by pinion and rack between indicator axle and the measurement lever.Improvements of the present utility model are: the head of described table body is a right cylinder, remainder is a cone, described dial plate is perpendicular to the table body axis, but at the head of table body the elastic jacket of phase his-and-hers watches body rotation is housed, and this elastic jacket is connected with an extension bar by universal joint again.During use, but the rotation of table body relative resilient chuck is arbitrarily angled, and elastic jacket can be done rotating of space any direction relative to extension bar by universal joint.So, just can make measuring head touch tested surface easily as long as this dial gauge is fixed near the measured object.
The transversal section of above-mentioned extension bar can be circular, but regular hexagon preferably, and this sample dial gauge both can be installed on any measurement bay, also can be installed on the knife rest of lathe or on other suitable annex.
Compared with prior art, the utility model is shown body elasticity chuck and the extension bar of being with universal joint owing to being provided with, so, as long as extension bar is fixed near the measured object, just measuring head can be moved on on the tested surface, not only use very conveniently, and can adapt to the needs of various occasions.In addition, with the table body be designed to taper shape can make measuring head extend into the hole than the depths, thereby can improve the clamping precision of measured object on lathe.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Accompanying drawing is the concrete structure figure of an example of the utility model.
As shown in the figure: the inner chamber of table body 1 is a conical cavity, and the outline of table body head 2 is cylindrical, and remainder 3 is conical.At table body head 2 elastic jacket 4 is housed, only need exerts oneself slightly, the table body just can freely rotate in chuck.Gauge outfit 5 is screwed in the end of table body, and its inner chamber is equipped with dial plate 6, indicator 7 and indicator axle 8, and a gear 9 wherein is being connected on the indicator axle 8.Measuring head 10 is identical with existing dial gauge with the syndeton of 11 on measuring head lever, that is: an end of measuring head 10 has groove, plays a part the elasticity folder, with the end clamping of measuring head lever 11, and be hinged on together on the bearing pin 12 of table end of body, tooth bar 13 is connected in the other end of lever 11.When measured object promotes measuring head 10 swings (towards the direction perpendicular to paper), measuring head also will drive lever 11 around bearing pin 12 swings, drive 8 rotations of indicator axles by gear 9 and tooth bar 13 again, and the displacement signal of measuring head 10 is passed to indicator 7.Lever 11 is to reset by the spring leaf 14 that is fixed in the table body.Universal joint 15 is made up of clamping plate 16 and two bulbs 17 that are clipped in wherein, and they link to each other with extension bar 18 with elastic jacket 4 respectively, thereby can make table body 1 do rotating of any direction relative to extension bar 18.The transversal section of extension bar 18 is a regular hexagon, extension bar stably can be installed on the lathe saddle or on the drill chuck like this.Rearward end at extension bar also has a cylindrical sector 19, so that extension bar is installed on Clamp of milling machine or the general dial framework.
Claims (3)
1, a kind of universal lever indicator, comprise table body (1), dial plate (6), indicator (7) and be positioned at the measuring head (10) of showing end of body, wherein be connected by pinion and rack between indicator axle (8) and the measurement lever (11), the head (2) that it is characterized in that described table body (1) is a right cylinder, remainder (3) is a cone, described dial plate is perpendicular to the table body axis, at the head of table body but the elastic jacket (4) of a phase his-and-hers watches body rotation is housed, this elastic jacket is connected with an extension bar (18) by universal joint (15) again.
2, dial gauge as claimed in claim 1, the transversal section that it is characterized in that described extension bar (18) is a regular hexagon.
