Abstract
The utility model discloses an inside diameter measurement rule relates to the industrial products production field. Including two measurement legs and a calibrated scale, every middle part of measuring the leg all is provided with the through -hole of three equal diameter, switches on through the rectangle through -hole between three through -hole, measuring the leg for two and connecting through a pivot, install respectively to the other end from the one end of pivot and screw up the nut, measure the leg, the leg is measured to the bearing, the bearing, and the nut is screwed up to the calibrated scale, indicate the angle and the radius conversion scale of three different gears on the calibrated scale respectively, the surface of calibrated scale sets up an annular slide of circle, installs two slip pointers in the slide. The beneficial effects of the utility model are that: internal diameter that can the great size work piece of accurate measurement is through in placing the pivot in different through -holes, can realize the gear conversion when measuring not unidimensional internal diameter, reaches the measurement requirement, scale when measuring can be remembered to the slip pointer, can realize after measuring the completion, takes out the back at the reading with inside diameter measurement rule in the work piece.
Description
Technical field
The utility model relates to industrial products production field.
Background technology
In the processing of boiler, petroleum refining equipment and the equipment such as pharmacy and chemical industry, often need measure large-sized pipe fitting interior diameter.Existing inside-diameter measuring tool has the multiple survey instruments such as clamp, vernier caliper, milscale, these survey instruments are all measure less instrument, face adopts Steel Ruler or steel tape to measure, not only precision is low but also efficiency is low, simultaneously less for opening, the workpiece that internal diameter is larger, is difficult to realize the measurement to internal diameter.
Utility model content
Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, a kind of inside-diameter measuring tool is provided, use the utility model can the internal diameter of Measurement accuracy large-size workpiece, simultaneously can realize flange workpiece and opening less, the inner diameter measurement of the larger workpiece of internal diameter, by being placed in different through holes by rotating shaft, can be implemented in gear conversion when measuring different size internal diameter, reach measurement requirement; Sliding pointer can measuring memory time scale, can be implemented in after measurement completes, at reading after being taken out in workpiece by inside diameter measurement gauge, measuring process is simple and convenient, and measuring accuracy is higher, substantially can realize industrial measurement requirement.
The technical solution adopted in the utility model is: provide a kind of inside diameter measurement gauge: comprise two and measure leg and an index dial, each measurement midleg is provided with three isodiametric through holes, by rectangular through holes conducting between three through holes; Measure leg for two to be connected by a rotating shaft, be separately installed with fastening nut from one end of rotating shaft to the other end, measure leg, bearing, measure leg, bearing, index dial, fastening nut; Index dial indicates respectively angle and the radius conversion scale of three different gears; The surface of index dial arranges a cirque slideway, is provided with two sliding pointers in slideway, and two sliding pointers lay respectively at the outside that two are measured leg.
Further optimization the technical program, the top of each measurement leg of inside diameter measurement gauge is provided with a threaded hole, and one of them is measured in the threaded hole on leg and installs a cock bolt.
Further optimization the technical program, the bottom of each measurement leg of inside diameter measurement gauge is provided with a contact ball.
Further optimization the technical program, inside diameter measurement gauge contact ball adopt hard material.
The utility model is compared with traditional measurement instrument, its beneficial effect is: 1, use the utility model can the internal diameter of Measurement accuracy large-size workpiece, simultaneously can realize flange workpiece and opening less, the inner diameter measurement of the larger workpiece of internal diameter, by rotating shaft being placed in different through holes, can be implemented in gear conversion when measuring different size internal diameter, reach measurement requirement; Sliding pointer can measuring memory time scale, can be implemented in after measurement completes, at reading after being taken out in workpiece by inside diameter measurement gauge, measuring process is simple and convenient, and measuring accuracy is higher, substantially can realize industrial measurement requirement; 2, after having measured, cock bolt can be measured leg by two threaded holes by two and fix, and is convenient to deposit; When 3, measuring, the inwall of contact ball and measured workpiece realizes point cantact, the measuring error caused when minimizing inwall is curved surface; 4, hard material improves the fastness to rubbing of contact ball, increases the service life.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, inside diameter measurement gauge comprises two and measures leg 1 and an index dial 2, and the middle part of each measurement leg 1 is provided with between three isodiametric through holes, 3, three through holes 3 by rectangular through holes conducting; Measure leg 1 for two to be connected by a rotating shaft 4, be separately installed with fastening nut 5 from one end of rotating shaft 4 to the other end, measure leg 1, bearing 6, measure leg 1, bearing 6, index dial 2, fastening nut 5; Index dial 2 indicates respectively angle and the radius conversion scale of three different gears; The surface of index dial 2 arranges the slideway 7 of an annular, is provided with two sliding pointers, 8, two sliding pointers 8 and lays respectively at the outside that two are measured leg 1 in slideway 7; The top of each measurement leg 1 is provided with a threaded hole 9, and one of them is measured in the threaded hole 9 on leg 1 and installs a cock bolt 10; The bottom of each measurement leg 1 is provided with a contact ball 11.
During use, cock bolt 10 is spun out from the threaded hole 9 of another measurement leg 1, make two to measure leg 1 to be separated, make two sliding pointers 8 of 7 li, slideway be close to two respectively and measure leg 1, and the initial position of instruction on index dial 2, according to the workpiece size that will measure, open the fastening nut 5 at rotating shaft 4 two ends, sliding shaft 4 is in suitable through hole 3, fastening nut 5 is tightened, the bottom measuring leg 1 is stretched into the inside of measured workpiece, to both sides wheel measuring leg 1, measurement leg 1 promotes sliding pointer 8 and slides in slideway 7, the number of degrees can be read in measuring process, also the number of degrees are read after measurement leg 1 can being taken out in workpiece, after measurement completes, measure leg 1 by two and be returned to initial position, rotary switch bolt 10, measure leg 1 by two to fix.
