Abstract
The utility model discloses a measurement device for a riveting structure. The measurement device comprises a housing body, a pressure plate which is fixedly connected to the top of a housing body through a screw and a dial indicator, the bottom end of which is inserted inside the housing body. A measuring rod is installed on the bottom inside the housing body. The top end of the measuring rod is connected with the tail end of the bottom of the dial indicator. The measuring rod with an elastic shrinkage function is installed inside the hollow housing body to measure the height of the pin head of a rivet; it is only needed to insert the pin head into the tail end of the housing body, and the dial indicator installed on the top of the housing body can accurately show the height dimension of the pin head through the shrinkage amount of the measuring rod; therefore, the measuring process becomes simple and fast, manpower and material resources needed to be consumed in the measuring process are greatly saved; and meanwhile, the measurement device also has the advantages of being high in precision and fast in speed.
Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of measurement mechanism of riveted structure, belongs to the clamp technology field of detecting.
Background technology
Riveted joint is a kind of conventional syndeton, utilize axial force, to in part rivet hole, follow closely bar pier slightly and form ailhead, the method that a plurality of parts are connected, the popular riveted joint of saying just refers to two plates that thickness is little, on the position connecting, burrows at need, then rivet is put in, with hitter, rivet is rivetted, and the method that two plates or object are linked together.For the higher part of some dimensional accuracy as shown in Figure 1, after its contact riveted joint, require to measure the height dimension of rivet head, traditional metering system is generally to adopt ruler class measurer to detect, but because nail masthead end is upsetting, be semisphere, area is less, and measuring basis is in mid-plane, adopt traditional ruler class measurer only to measure and can increase error, and need expend more manpower and materials, and then affect the dimensional accuracy of fabricated part, cause the appearance of more substandard products.
Utility model content
In order to solve the problems of the technologies described above, the utility model aim to provide a kind of simple in structure, easy to use, accuracy of detection is high, the measurement mechanism of long-lived riveted structure.
The utility model is achieved through the following technical solutions:
A measurement mechanism for riveted structure, comprises housing, through screw, is fixed in the pressing plate of case top, the dial gauge in bottom insertion housing; Described housing inner bottom part is provided with gauge rod, and this gauge rod top is connected with dial gauge bottom end.
Described dial gauge inserts in the segmentation in housing and is socketed with chuck, and chuck is fixed by being arranged on the lock-screw of housing one side.
Between described chuck and gauge rod, be provided with elastic recovery mechanism.
Described elastic recovery mechanism is spring.
Described lock-screw and housing outer wall are perpendicular.
Described housing bottom has pore.
Described screw is sunk screw.
The beneficial effects of the utility model are:
Compared with prior art, the measurement mechanism of the riveted structure that the utility model provides, by being installed in the housing of hollow, measures a gauge rod with elastic shrinkage function the height of rivet head, only ailhead need be embedded to shell end, the dial gauge that install on housing top just can accurately demonstrate by the amount of contraction of gauge rod the height dimension of ailhead, the measuring process simple and fast that becomes, has significantly saved the manpower and materials that measuring process need expend, and also has high, the fireballing advantage of precision simultaneously.

Fig. 1 is the structural representation of tested part;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is use view of the present utility model;
Fig. 4 is the enlarged drawing of dotted portion A in Fig. 3;
In figure: 1-housing, 2-gauge rod, 3-spring, 4-chuck, 5-screw, 6-pressing plate, 7-lock-screw, 8-calibration block, 9-dial gauge, 10-rivet, 11-tested part.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;
As shown in Figure 2, the measurement mechanism of the riveted structure that the utility model provides, comprises housing 1, through screw 5, is fixed in the pressing plate 6 at housing 1 top, the dial gauge 9 in bottom insertion housing 1; Described housing 1 inner bottom part is provided with gauge rod 2, and these gauge rod 2 tops are connected with dial gauge 9 bottom end.
For described dial gauge 9 is fixed, prevent that measuring process from slip occurring and cause error to increase, in the segmentation that dial gauge 9 inserts in housings 1, be socketed with chuck 4, chuck 4 is fixed by being arranged on the lock-screw 7 of housing 1 one sides.
In order to promote measurement efficiency, between described chuck 4 and gauge rod 2, be provided with elastic recovery mechanism 3, often measuring a part ，Gai elastic recovery mechanism 3 can promote gauge rod 2 downwards to reset, and is convenient to the measurement of next part.
In order to guarantee the object of elastic recovery, and control cost, described elastic recovery mechanism 3 is spring.
Described lock-screw 7 is perpendicular with housing 1 outer wall, and screwing with unclamp operation of lock-screw 7 is more easily convenient.
In order to guarantee precision, between gauge rod 2 and housing 1, for to be closely connected, in described housing 1 bottom, have pore 12, the interior generation of housing 1 area of low pressure when it can prevent from moving on gauge rod 2, saves labour.
In order to prevent that screw 5 from stretching out housing 1 outside, hamper measurements process or scuffing staff, described screw 5 is sunk screw.
Embodiment: during work, need to measure tested part 11 as shown in Figure 1, on this tested part 11, rivet 10 is installed, and rivet 10 tops are jumping-up semicircular in shape, first with the calibration block 8 of flat-top, housing 1 and gauge rod 2 are calibrated, both end is flushed to be as Fig. 3, state shown in 4, again tested part 11 and rivet 10 are placed in to housing 1 bottom, again rivet 10 is embedded completely in housing 1 to tested part 11 end faces and flush with housing 1 bottom surface, rivet 10 tops and the gauge rod 2 that embed join, promote to move up on gauge rod 2, gauge rod 2 promotes the end of dial gauge 9, the displacement of gauge rod 2 shows by dial gauge 9, the demonstration data of dial gauge 9 are the size of rivet 10.After measurement completes, tested part 11 is unloaded, under the effect of the elastic recovery mechanism 3 of making at spring, gauge rod 2 moves down reset, just can carry out the detection of next part.
