Embodiment
This example is improvements over the prior art, main improvements are for what time following: the one, and clamp pin shortens in design greatly, and to survey the groove footpath of φ 80, slot pitch end face 200mm is example, this clamp total length only need about 320mm just can, and clamp overall length before need to design at 800mm. The 2nd, micrometer screw gauge 6 is installed on clamp, certainty of measurement improves greatly. Micrometric screw 7 and microdrum 12 are provided with exact scale, and the certainty of measurement of microdrum 12 reaches 0.02mm. The 3rd, measuring is no longer to judge that dimensional tolerance is whether within the scope of minimum and maximum groove, but directly reads concrete dimension figure. The 4th, it is large that diameter measurement scope becomes, and has certain versatility, as long as diameter is poor in 20mm, same clamp all can be measured, and such as φ 80 clamp that design, can measure the groove diameter of arbitrary dimension and tolerance between φ 70～φ 90mm. The 5th, measure groove depth scope and strengthen, the former clamp dark groove of end face 150mm of can finding range at most, and the present dark groove of clamp maximum detection 400mm.
Fig. 1 is structural representation of the present utility model, and these clamp are by left caliper 1, right caliper body 2, and screw 3, spring 4, steady pin 5 and micrometer screw gauge 6 form. Micrometer screw gauge 6 is made up of fixed muffle 9, microdrum 12, micrometric screw 7 and baffle plate 13. Left caliper 1 is connected by screw 3 with right caliper body 2, on screw 3, cover has spring 4, and left and right caliper is provided with steady pin 5 by screw 3 places, and the two ends of spring 4 are just stuck on steady pin 5, due to the effect of spring 4, make clamp contact touch detected workpiece 18 groove inwalls to external expansion. Clamp contact is 200mm to the distance of screw 3, the position that clamp are installed micrometer screw gauge 6 is 100mm to the distance of screw 3, ratio is 2:1, therefore, according to similar triangle theory, the size of clamp contact (φ 80mm) is 2 times of clamp galianconism end micrometer screw gauge 6 installation place clamp handle distances (φ 40mm). The contact of clamp contacts with tested groove, and the distance between contact is the diameter of internal bore groove namely, as long as therefore measure the distance between clamp galianconism end two clamp handles, according to 2 times of relations, so caliper body contact pitch from, the diameter of groove also just measured. On the clamp handle of clamp galianconism end, micrometer screw gauge 6 is installed, this device can directly be measured the distance between clamp galianconism end clamp handle. Owing to having adopted differential measurement principle, so certainty of measurement improves greatly.
Fig. 4 is the schematic diagram that adopts caliper measurements endoporus groove of the present utility model. The contact of clamp contacts with detected workpiece 18 bottom lands, and the distance between the contact of left and right two caliper bodies is the diameter of groove. Clamp contact is to the distance (200mm) of screw for screw is to the twice of micrometer device distance (100mm), and therefore the size between clamp contact (80mm) is the twice of the distance (40mm) between clamp galianconism end two clamp handles. According to twice relation, as long as measure the distance between galianconism end clamp handle with micrometer screw gauge 6, just can draw the diameter (for 2 times of galianconism end clamp handle size) of groove.
As shown in Figure 2, micrometer screw gauge is made up of fixed muffle 9, microdrum 12, micrometric screw 7, baffle plate 13. Fixed muffle 9 one end and right caliper body 2 pommels are welded and fixed, and fixed muffle 9 right-hand members are provided with internal thread, and with micrometric screw 7 external screw thread precision-fit, pitch is designed to P=0.5mm. Microdrum 12 inside are unthreaded hole, with fixed muffle 9 outer round surface matched in clearance. When installation, micrometric screw 7 through the through hole left caliper 1 and right caliper body 2, then rotates micrometric screw 7 by fixed muffle 9 threaded interior holes from left end, and micrometric screw 7 right-hand members are smooth cylinder, with baffle plate 13 endoporus interference fits. After baffle plate 13 inner hole sleeves are on micrometric screw 7 cylinder tables, the axial distance of regulating fender 13 and microdrum 12,0 graduation mark on microdrum is overlapped with the datum line 17 of fixed muffle 9, then on fixed muffle 9, engrave graduation mark, make the left end end face of microdrum 12 just aim at 80mm place groove (see figure 3). After groove is all portrayed, baffle plate 13 and micrometric screw 7 cooperation place welding, microdrum 12 is also welded and fixed with baffle plate 13, and baffle plate 13 and microdrum 12 and micrometric screw 7 are connected as a single entity. Because pitch is 0.5mm, so microdrum 12 often revolves turn around (being rotated in the forward clockwise), microdrum 12 moves 0.5mm near right clamp handle left, be that the distance of the galianconism of clamp shown in Fig. 1 end two clamp handles reduces clamp upper end contact pitch that 0.5mm(is corresponding from reducing 1mm), on the contrary, if microdrum 12 counter-rotates a circle, the clamp upper end contact pitch that clamp handle spacing increase 0.5mm(is corresponding is from increasing 1mm). Size between two clamp handles is by fixed muffle 9 axial graduation marks (linear staff) and radially graduation mark (annular scale) sense data of microdrum 12.
