The novel device for measuring the size of the outer chamfer overcomes the defect of relative large measurement error of a present measurement method, and realizes accurate measurement.

Description

A kind of device of the outer neck chamfer dimesion of new measurement
Technical field
The present invention relates to a kind of device measuring outer neck chamfer dimesion, belong to mechanical cold working in-site measurement field.
Background technology
Outer neck chamfering cannot measure outer neck chamfer dimesion in plant site at present at the scene with general measurer direct measurement Mainly using slide calliper rule, the major defect of this method is that the side measurement end of slide calliper rule can not be contacted with chamfering end points to method, another Side measurement end accurately can not be contacted with the end points of chamfering, and therefore measurement error is larger, about 0.1~0.5mm(note: because of operator Vision and measurement level different and have larger difference).
Content of the invention
Present invention aim at providing a kind of device of the outer neck chamfer dimesion of new measurement that can accurately measure.
Realize above-mentioned purpose, the technical scheme that the present invention takes is as follows:
A kind of device of the outer neck chamfer dimesion of new measurement, including support, Special dial indicator, lock-screw and lock sleeve;Described Support one end be V-shaped body, the support other end is cylinder, and the intersecting end of described V-shaped body and cylinder are made as one, institute The cylindrical center stated is provided with the large diameter hole communicating and small diameter bore vertically, and described large diameter hole is located at cylinder Outer end, described lock sleeve is bushed in large diameter hole, and described Special dial indicator is made up of gauge outfit and table bar, described Table bar one end of Special dial indicator is affixed with the bottom of the gauge outfit outer circumference surface of Special dial indicator, and the table bar of Special dial indicator is another End is inserted in lock sleeve, and cylindrical side wall is radially provided with screwed hole, and described lock-screw screws in cylindrical spiral shell In pit, the screw rod end of lock-screw is resisted against on the table bar of Special dial indicator.
The present invention with respect to the beneficial effect of prior art is:
The present invention proposes a kind of device of the outer neck chamfer dimesion of new measurement, overcomes the measurement error of existing measuring method relatively Big shortcoming it is achieved that high precision measurement (error of former measuring method is about 0.1~0.5mm, the measurement error of the present invention≤ 0.01mm).
Brief description
Fig. 1 is the main structure diagram of the device of the outer neck chamfer dimesion of a kind of new measurement of the present invention;
Fig. 2 is the main structure diagram to table part of the device of the outer neck chamfer dimesion of a kind of new measurement of the present invention.
Wherein: 1- support, 2- Special dial indicator, 3- lock-screw, 4- lock sleeve, 5- are to table part, 6-v type body, 7- cylinder Body, 8- gauge outfit, 9- table bar.
Below in conjunction with the accompanying drawings technical scheme is further described, but is not limited thereto, every to this Inventive technique scheme is modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover In protection scope of the present invention.
Specific embodiment
Specific embodiment one: with reference to shown in Fig. 1, a kind of device of the outer neck chamfer dimesion of new measurement, including support 1, Special dial indicator 2, lock-screw 3 and lock sleeve 4;Described support 1 one end is V-shaped body 6, and support 1 other end is cylinder 7, And the intersecting end of described V-shaped body 6 and cylinder 7 are made as one, the center of described cylinder 7 is provided with vertically and communicates Large diameter hole and small diameter bore, described large diameter hole is located at the outer end of cylinder 7, and described lock sleeve 4 is bushed in straight greatly Footpath in the hole, described Special dial indicator 2 is made up of gauge outfit 8 and table bar 9, described table bar 9 one end of Special dial indicator 2 with special The bottom of gauge outfit 8 outer circumference surface of dial gauge 2 is affixed, and table bar 9 other end of Special dial indicator 2 is inserted in lock sleeve 4, cylinder Screwed hole is radially provided with the side wall of body 7, described lock-screw 3 screws in the screw thread in the hole of cylinder 7, lock-screw 3 Screw rod end is resisted against on the table bar 9 of Special dial indicator 2.
Specific embodiment two: as shown in figure 1, the outer neck chamfer dimesion of the new measurement of the one kind described in specific embodiment one Device, described lock-screw 3 is provided with external screw thread for one end, the other end is provided with the stepped cylinder body of reticulate pattern knob.
Specific embodiment three: as depicted in figs. 1 and 2, outside the new measurement of the one kind described in specific embodiment one or two The device of neck chamfer dimesion, the device of the outer neck chamfer dimesion of described new measurement is also included to table part 5;Described to table part 5 The outer contour shape of vertical section is trapezoidal, and the V-shaped face of table part 5 and the V-shaped body 6 of support 1 is fitted close.
The Special dial indicator reading of the present invention and chamfer dimesion are 1:1 relation, achievable direct reading (note: can basis Chamfer angle to be measured difference is carved with the different scale of radius, to realize a-table-multi-purpose on dial plate), to table part 5 be with and treat Survey the prismatoid (note: the actual value of the chamfering to table part 5 for the hypothesis is a) of chamfering nominal value or intermediate value same size chamfering.
First by the V-shaped face of the V-shaped body of support 1 and two opposite flanks tight fits to table part 5 during use, then rotate The dial plate of Special dial indicator 2, makes indicator corresponding with zero point on dial plate, then by the two sides of the V-shaped body of support 1 and chamfering to be measured Be in close contact, afterwards from the dial plate of Special dial indicator 2 reading it is assumed that be b(note: b value can just can be born, with Special dial indicator 2 table During pin elongation, indicator direction of rotation is forward direction, otherwise is negative sense), then chamfering measured value to be measured is a+b.
According to the difference of certainty of measurement, Special dial indicator 2 can also be with the table of amesdial or other precision.
