Abstract
The utility model provides an internal diameter testing instrument for testing the internal diameters of a circle or a spherical shell (workpieces). The utility model is characterized in that a left and a right support rods II (14), II (16) are arranged on an instrument stand (11), and the instrument stand (11) is held on the inner wall of a casing by a positioning screw (3); a scale stand (5) which can do horizontal rotation is connected with the instrument stand (11) by a coupling shaft (8); a retractable auxiliary scale ii (15) is arranged on the scale support (5); a main scale (1) is arranged on the auxiliary scale ii (15). The utility model is more ideal for testing the circle or the spherical shell (workpieces) with the internal diameter of 500 mm-10000 mm for general precision (>+-0.5 mm).
Description
The utility model is applicable to machine-building, particularly garden, aspect shape or the detections of spherical shell (workpiece) general precision (＞± 0.5 millimeter) internal diameter such as chemical machinery manufacturing and installation.
At present, the test section of garden shape or spherical shell (workpiece) internal diameter is the method that adopts checks such as micrometer inside caliper or vernier scale, to the overwhelming majority than major diameter, garden shape that accuracy requirement is not high or spherical shell (workpiece) are not suitable for detecting with the above-mentioned method of inspection, and check is very difficult when particularly assembling at the scene.Task of the present utility model is acquisition a kind of general (10000 millimeters of φ 500～φ), simple in structure, is convenient to the interior tray (well) diameter detector of making, using and carry.
The utility model is by main scale (1), pair chi I (2), dog screw (3), pair chi frame I (4), chi frame (5), left support bar I (6), left side lengthening frame I (7), coupling spindle (8), angle scale (9), screw (10), instrument frame (11), right lengthening frame I (12), right support bar I (13), left support bar II (14), pair chi II (15), right support bar II (16) is formed (seeing accompanying drawing).Telescopic pair of chi frame I (4) ［ internal diameter is connected into when being 500～800 millimeters and pays chi II (15) ］ is housed on the chi frame (5) that can horizontally rotate, pay chi frame I (4) telescopic pair of chi I (2) is housed, pay on the chi I (2) movably main scale (1) is housed; Pay on the chi I (2) and be carved with the chi datum line, being carved with the millimeter on the main scale (1) is the scale (50～± 50 millimeters) of unit; Be fixed with the angle scale (9) of one 360 degree on the instrument frame (11), and arranged on left and right sides is equipped with left side lengthening frame I (7) respectively, ［ internal diameter changes left support bar II (14) into to right lengthening frame I (12) when being 500～800 millimeters, right support bar II (16) ］, left side lengthening frame I (7) is equipped with telescopic left support bar I (6), right support bar I (13) respectively on the right lengthening frame I (12); Chi frame (5) and instrument frame (11) link together by coupling spindle (8); Chi frame (5), pay chi frame I (4), instrument frame (11), about extend and dog screw (3) all be housed on frame (7), (12).Adjust during detection support bar make it to be supported on survey on the diameter of garden, adjust and pay the datum length that chi is determined the garden radius of surveying, mobile main scale makes it to contact with survey garden housing (workpiece) inwall, the numerical value that reacts on main scale is the radius error of this point, rotation chi frame can obtain the error on the different angles radius, the maximal value of error identifying is this garden maximum gauge error.
The utility model can satisfy machine-building, particularly the internal diameter check of aspect general precisions (＞± 0.5 millimeter) requirements such as chemical machinery manufacturing and installation.Be not suitable for high-precision internal diameter check.
For ease of making, use and carrying, pay chi frame I (4), left side lengthening frame I (7) and (12) three of right lengthening frame I and be designed to general part (length is 500,1000 millimeters); Left side support bar I (6) is designed to general part (length is 500,1000 millimeters) with right support bar I (13); Right support bar II (14) is designed to general part with right support bar (16); According to its combination of the big young pathbreaker of survey internal diameter.In addition, the each several part material therefor should have good wear-resisting indeformable, the performance that is difficult for getting rusty, and the main scale scale is wanted accurately, and want suitably in the each several part gap, so that move and guarantee that precision is easy.
