Detailed description of the invention
Below in conjunction with accompanying drawing, this technology is described further:
Shown in Fig. 1, Fig. 2, a kind of direct reading integral type clamp, including being symmetrical arranged, by a pair tong arm 10 of rotational pin 9 cross-articulation, each tong arm 10 is clamping section 11 in the side of rotational pin 9, and opposite side is reading section 12；Clamping section 11 end is provided with dop 2 adjustable with tong arm 10 angle in the plane that a pair tong arm 10 determines, two dops 2 that front end is tip are symmetrical arranged, it is interior card (shown in Figure 3) when dop 2 slopes inwardly, is wild card (shown in Figure 4) when dop 2 is outward-dipping；It is additionally provided with reading plotter in reading section 12.
The thickness of tong arm 10 is certain, and it is 6mm that empirical data chooses the thickness of tong arm 10, and for ensureing the rigidity of tong arm 10, with rotational pin 9 place for boundary, the two ends of tong arm 10 are all equi intensity cantilever.
It is additionally provided with the locking device for a pair tong arm can be locked in certain angle in clamping section.Locking device includes the locking plate 16 offering mounting hole 15 above, and mobile two lock-screws 4 being arranged in mounting hole 15, a lock-screw 4 is linked by screw thread pair with a tong arm 10.
For reducing frictional force when lock-screw 4 moves in mounting hole 15, mounting hole 15 is in circular arc, and the pitch radius of circular arc is the spacing of rotational pin 9 and lock-screw 4.
Dop is rotatably arranged in clamping section end by controlling screw, is separately provided for limiting dop 2 in the both sides, rear end of dop 2 and is angled inwardly into the positive stop lug boss 14 of extreme position and the outward-dipping positive stop lug boss 13 to extreme position.
The effect controlling screw 3 rotates offer rotating shaft for dop 2 on the one hand, also acts as the effect of lock-screw on the other hand, it is possible to be locked on extreme position by dop 2.
When dop 2 slopes inwardly, positive stop lug boss 14 limits the angle between dop 2 axis and clamping section 11 axis as 12 °, and now, these direct reading integral type clamp are interior card；When dop is outward-dipping, positive stop lug boss 13 limits the angle between dop 2 axis and clamping section 11 axis as 25 °, and now, these direct reading integral type clamp are wild card.
The front end of dop 2 is wedge shaped or taper.
Reading plotter includes the trisquare 18 offering circular arc waist row hole 17 above, move two leads 5 being arranged in waist row hole 17, one lead 5 is connected with a tong arm 10, is provided with the graduation mark 6 corresponding respectively to wild card length and Nei Ka length on the two sides of trisquare 18.
For reducing frictional force when lead 5 moves in mounting hole 17, mounting hole 17 is in circular arc, and the pitch radius of circular arc is the spacing of rotational pin 9 and lead 5.
Trisquare 18 can be always symmetrical about the middle separated time of these direct reading integral type clamp, equidistant movement (state of diagram) when two leads are mobile in mounting hole 17, now the center line of the graduation mark 6 of trisquare 18 is " 0 " graduation mark, and note needs to be added the reading on " 0 " graduation mark both sides when reading measurement result.It is of course also possible to only one of which lead is mobile in mounting hole 17, another lead only plays and trisquare 18 is fixed on the effect on tong arm 10, and now " 0 " graduation mark of trisquare 18 is positioned at the side that lead is motionless, can visual reading during note reading measurement result.
Owing to these direct reading integral type clamp can have Nei Ka and wild card two states, therefore be all provided with graduation mark on the two sides of trisquare 18 corresponding with Nei Ka and wild card respectively.
Be further opened with relative groove 7 in two reading section 12 rear ends, groove 7 can use slide gauge to carry out card pin (not shown) measured directly for placement.
During use, determine the state of clamp, i.e. inside plain calipers or bow compass according to measurement target, make span of jaw corresponding with measuring target linear dimension according to common clamp operating specification, corresponding graduation mark directly reads measurement result.
This technology provides the benefit that:
Direct reading integral type clamp described in this technology, are the multi-functional clamp that can directly measure part arm thickness, internal diameter.The reading plotter of these multi-functional clamp can directly read millimeter, it is also possible to reads with slide gauge and counts more accurately；The available screw that controls of clamping section is adjusted to Nei Ka and wild card, and locking device is for fixing clamp position during reading；Reading plotter is the trisquare reading plotter utilizing the principle of similitude of triangle to make, and fluted can so that vernier caliper reading.
These direct reading integral type clamp, it is possible to have Nei Ka and wild card two states, it is possible to direct reading, can meet measurement requirement direct, effective, and easy to use, simple in construction, processing technology is better.
