Abstract
The utility model relates to a digital display caliper rule used for measurement of hole heart distance used for measuring the distance between two hole hearts in the component on-site assembly in the mechanical processing industries. Digital display caliper rule used for measurement of hole heart distance comprising a rule body, two movable measuring jaws, a digital display, a fastening screw I, a fastening screw II, a fine adjustment knob and a control press button. The utility model is characterized in that two movable measuring jaws are provided with holes used for installing non-magnetic sleeve pipes, which are respectively disposed in the holes of the two movable measuring jaws; two circular magnetic sheets, two step shafts, and two non-magnetic conversion rods are respectively disposed in the two non-magnetic sleeve pipes; two measuring rods are respectively disposed on the two non-magnetic conversion rods. The utility model has advantages of measuring the hole heart distance on site, improving the precision of the hole heart distance measurement, facilitating the use, and reducing the costs.
Description
Technical field: the invention is used for the very little measurement of mechanical processing industry parts erecting yard two Kong Kongxin carpenters squares.
Background technology: in mechanical processing industry after regular meeting the assembling of some parts that have pilot hole occurs and finishes; the situation that follow-up parts dress unmatches; this moment is in order to verify the correctness of assembling center, parts hole; need carry out the detection of hole heart distance to assembling parts; for the parts that much assembled; because can't dismantle; so can only take the on-the-spot mode that detects; but be not used in the conventional sense measurer that erecting yard detects hole heart distance at present; and present routine inspection measurer digital display calliper; because the measurement end face of two mobile measuring jaws is the face contact; and be used for the hole heart when detecting; because be to measure end face to contact, so have measuring error with routine inspection measurer digital display calliper heart distance with arc surface in the hole.
Summary of the invention: the purpose of the invention provides a kind of erecting yard hole heart that can effectively solve and is used for the hole heart apart from the digital display calliper that detects apart from what detect demand; The purpose of the invention is to realize by following technical scheme: be used for the hole heart apart from the digital display calliper that detects, comprise blade, mobile measuring jaw, digital indicator, trip bolt I, trip bolt II, vernier adjustment knob and control knob, it is characterized in that on two mobile measuring jaws, make the hole that non-magnetosheath pipe is installed, non-magnetosheath pipe is contained in respectively in two holes on the mobile measuring jaw, two round magnetic sheets are contained in respectively in two non-magnetosheath pipes, two multidiameters are contained in respectively in the non-magnetosheath pipe, two non-magnetic adapting rods are contained in the non-magnetosheath pipe, two sounding rods are contained in respectively on two non-magnetic adapting rods.
The advantage of the invention: can effectively detect hole heart distance at erecting yard, improve the precision of erecting yard detection hole heart distance, easy to use, low cost of manufacture.
Description of drawings:
Fig. 1 is used for the hole heart apart from the digital display calliper structural representation that detects;
Fig. 2 is to use and is used for the hole heart detects hole heart distance apart from the digital display calliper that detects instance graph.
Among Fig. 1: 1, blade 2, non-magnetosheath pipe 3, circle magnetic sheet 4, multidiameter 5, non-magnetic adapting rod 6, sounding rod 7, control knob 8, vernier adjustment knob 9, mobile measuring jaw 10, digital indicator 11, trip bolt I 12, trip bolt II
Embodiment: be used for the hole heart apart from the digital display calliper that detects, comprise blade, mobile measuring jaw, digital indicator, trip bolt I, trip bolt II, vernier adjustment knob and control knob, it is characterized in that on two mobile measuring jaws, make the hole that non-magnetosheath pipe is installed, with non-magnetosheath pipe respectively interference be contained in two holes on the mobile measuring jaw, non-magnetosheath pipe plays magnetic screening action, with two round magnetic sheets respectively interference be contained in two non-magnetosheath pipes, with two multidiameters respectively transition fit be contained in the non-magnetosheath pipe, two non-magnetic adapting rod transition fit are contained in the non-magnetosheath pipe, non-magnetic adapting rod and multidiameter interference fit, with two sounding rods respectively interference be contained on two non-magnetic adapting rods.Make the hole that multidiameter is installed in non-magnetic adapting rod one end in the heart, make the hole that vertical center line installs and measures bar at the non-magnetic adapting rod other end.Multidiameter, non-magnetic adapting rod and sounding rod are combined the formation measuring head, and the sounding rod in the measuring head becomes series according to the different designs of the diameter of measured hole and length, the sounding rod different according to the different choice of tested pore size during measurement.
Practical measuring examples:
As shown in Figure 2, among Fig. 2: A-two hole outward flange vertical range B-two hole inward flange vertical range L-two hole centre distance 13-detect the 1st hole 14-of example and detect the 2nd hole of example
Is example with the hole heart that detects the 2nd hole of example apart from L to detect as detecting the 1st hole of example among Fig. 2, L=(A+B)/2, and the choice criteria of the sounding rod diameter dimension of selection is the diameters of two sounding rod diameter sums less than minimum aperture; Move the mobile measuring jaw of digital display calliper during measurement, make two sounding rod contacts, the digital display calliper zero clearing; Mobile measuring jaw, make two sounding rods as shown in Figure 2 tangent with the inboard cambered surface that detects the 1st hole of example and the 2nd hole of detection example respectively, this moment digital display calliper reading be sounding rod respectively with detect the 1st hole of example and the tangent distance of inboard cambered surface that detects the 2nd hole of example, size B be sounding rod respectively with detect the 1st hole of example and the tangent distance of inboard cambered surface that detects the 2nd hole of example; Mobile measuring jaw, make two sounding rods as shown in Figure 2 tangent with the outside cambered surface that detects the 2nd hole in the 1st hole of example and detection example respectively, this moment digital display calliper reading be sounding rod respectively with detect the 1st hole of example and the tangent distance of outside cambered surface that detects the 2nd hole of example, size A be sounding rod respectively with detect the 1st hole of example and add 2 times of sounding rod diameters with the tangent distance of outside cambered surface that detects the 2nd hole of example; Can try to achieve thus the two hole hearts apart from L be sounding rod respectively with detect the 1st hole of example and the tangent distance of inboard cambered surface that detects the 2nd hole of example add sounding rod respectively with detect the 1st hole of example and add 1/2nd of 2 times of sounding rod diameter sums again with the tangent distance of outside cambered surface that detects the 2nd hole of example.
