Abstract

The dial gauge may be used to perform several measurement. Its bearing handle consists of connected screw bolt and nut and is provided with various measuring heads of different shapes and sizes and related sample rods. It can be used in the measurement of outer diameter, inner hole, inner and outer thread, depth, length, verticality and wall thickness of workpieces and thus facilitates the measurement in machine building.

Description

Multifunctional ultralimit dial gauge

The present invention is a kind of milscale, more precisely is the ultralimit dial gauge of multiple measurement function of collection and one.

The used milscale of mechanical processing industry has outside micrometer, micrometer inside caliper, micrometric depth gauge, screw-thread micrometer, wall thickness micrometer gauge etc. at present.Various milscales are because to be subjected to the restriction of adjuster bar can only establish 25mm be a kind of specification, that is to say the size that to measure in 0～100mm scope, must 4 just can meet the demands milscale, measure other endoporus and screw thread etc. again, the milscale that is equipped with is just more, measure the precision workpiece of larger diameter if desired, because of not possessing large-scale measurer, guarantee very difficulty of precision man-hour adding.

The present invention supports outside micrometer commonly used being connected with screw rod, nut, enlarge measurement range, gauge head and the lining bar of being furnished with all size shape again just make common outside micrometer become and have the multi-functional milscale of measuring inside and outside circle diameter, internal and external threads, the degree of depth and wall thickness.

Accompanying drawing 1 is the multifunctional ultralimit dial gauge structural drawing.

Accompanying drawing 2,3,4 is the lining bar of this milscale.

Accompanying drawing 5,6,7,8,9,10,11 is the gauge head of this milscale.

Describe the application of this invention in detail below in conjunction with accompanying drawing 1～11.

With reference to accompanying drawing 1～11.Supporting of the present invention is formed by connecting 6,8,21,22 by screw rod 31,10,11 and nut 5.

When measuring the external diameter diameter, if measurement range super large, can unclamp central nut, the supporting on the left side backward the pine,

gauge head

3,24 is contacted with the lining bar of Fig. 3 in position, after the two sides of lining bar and measuring staff face are adjacent to fully, with nut supporting fixing dead, and then with its position, lining bar school.Milscale as 25mm～50mm, measure the above diameter of 50mm, when measuring staff pine during to the 50mm left and right sides, the lining bar of 50mm is placed on wherein check and correction, adjust micrometer adjusting screw 1, make the scale mark of setting nut 4 aim at 0, lock-screw 2 lockings, milscale at this moment has been the milscale of 50mm～75mm.If measuring staff center line 25 is not more than the workpiece radius of being surveyed from the distance that supports 26, then the attaching nut on both sides can be unclamped, supporting 6,21 to rise, the verticality on both sides is as the criterion with center line 7,17, the depth of parallelism on both sides is as the criterion with parallel surface and line 27,28, when measuring large diameter, connecting screw rod can adopt double nut locking when adding very longly.

If measurement range when extra small, can directly be enclosed within the gauge head of accompanying drawing 7 on 3,24 measuring staffs of accompanying drawing 1 and measure, lining bar should be proofreaded so that calculate added length before measuring.

In the time will measuring diameter of bore, on measuring staff, put the gauge head of accompanying drawing 9, both sides are respectively overlapped 1, position check and correction scale mark with the

fluting lining bar

18,32 of accompanying drawing 2, with gauge head 13 contact endoporus arc surfaces, measure the diameter of endoporus with 13 gauge heads of another activity, measuring method is oppositely measured for intersecting, because of 14 of gauge head portion is symmetrical flat, so in measured scope, can not collide.

When measuring the internal and external threads size, change the gauge head of accompanying drawing 6, accompanying drawing 8 or accompanying drawing 10 accompanying drawings 11, accompanying drawing 8 or accompanying drawing 10 gauge heads are placed on the fine setting measuring staff, accompanying drawing 6 or accompanying drawing 11 gauge heads are placed on the movable measuring staff, with the point of accompanying drawing 6, accompanying drawing 8 or accompanying drawing 10, accompanying drawing 11, the lining bar of 15,16 pairs of good accompanying drawings 4 of groove, and can measure the internal and external threads size of all size.The method of measuring internal thread is identical with the method for measuring diameter of bore.The gauge head of internal thread can rotate, and the hole 12 of its gauge head (hole that comprises other gauge head) is that best clearance cooperates with cooperating of measuring

staff

3,24, and contact length can be decided according to measuring kind.

In the time will fathoming, the nut of centre is unclamped, make the left end supporting changeing a direction to the left or to the right, or the nut on the right unclamped, make supporting the 6 loose segment distances that make progress, put the degree of depth measuring staff of accompanying drawing 5 again, come lining bar or scale with reference field 29 or 30, just can fathom then, to the degree of depth very dark can change long measuring staff, just the part of exposing is interlocked up and down with two of accompanying drawing 2 fluting lining bars and proofreads scale, above the recessed part 19 of the part 20 protruded of lining bar and following lining bar be harmonious, and but the school goes out from reference field 29 or 30 distances to overlapping gauge head leading section, then and the distance that can fathom.

When measuring the wall thickness dimension of pipe fitting, only need the gauge head of Fig. 9 is contained on the fine setting screw rod 3, withstand its hole wall with the arc surface of gauge head 13, and can directly measure the size of tube wall thickness.

Lock-screw 23 is locking after measurement finishes, so that observation post surveys size.

The scale 9 of the main inferior horn of this milscale and right angle can be measured length and check step verticality smoothly when the measuring workpieces periphery, more convenient.

The gauge head of this milscale can adopt the method that is threaded with being connected also of measuring staff; but end must have one section less than the polished rod part at the bottom of the measuring staff external thread wire in face of the survey of gauge head; so that the surface of contact of protection measuring staff; the shape of gauge head also can be designed and manufactured into other shape and specification according to special requirement, as trapezoidal internal and external threads gauge head, worm screw gauge head etc.

Multifunctional ultralimit dial gauge, not only the function of multiple milscale molten be one, satisfied the multiple measurement requirement of all size workpiece, but also filled up the blank that outside micrometer is measured endoporus and miking internal thread size, in the manufacturing of measurer, also greatly reduce cost, the development of mechanical industry is cut much ice.
