Summary of the invention
In order to overcome above shortcoming, the purpose of this utility model is to provide that a kind of measurement is accurate, and easy to adjust, ergometry is little, the large and continuously adjustable product inner diameter measuring device of measurement range of measurement range.
For achieving the above object, the utility model is by the following technical solutions: a kind of inner diameter measuring device, the shaped as frame that described inner diameter measuring device is opening upwards, it comprises the fixed support of a side and the traversing carriage of opposite side, fixed support and traversing carriage form respectively shaped as frame limit, both sides, the fixed support bottom transverse is provided with sleeve, the traversing carriage bottom transverse is provided with link mandrel, link mandrel one end is inserted in sleeve, and the drive traversing carriage synchronously horizontally slips along sleeve, fixed support and traversing carriage top are arranged with vertically extending support chip outside the shaped as frame opening, the fixed support middle part is provided with static probe, the traversing carriage middle part is provided with dial gauge, test rod and the static probe on fixed support of dial gauge are positioned at the same level height.
The utility model adopts above structure, during the testing product internal diameter, the support chip of fixed support and both sides, traversing carriage top can be erected to the product inner diameter end, then fixed support and traversing carriage are put into to the product internal diameter, first the static probe on fixed support is butted on to product one side inwall, then adjust link mandrel by slip, link mandrel is synchronizeed with traversing carriage to slide to product opposite side inwall, and the test rod that makes the dial gauge on traversing carriage is butted on product opposite side inwall, the test rod of dial gauge and the spacing between the static probe on fixed support are the product internal diameter like this, can obtain the product internal diameter from the reading of dial gauge.
Adopt above structure, adjust link mandrel by slip, thereby can measure the product of different inner diameters size, measurement range is large, and this adjusting operation is convenient, and adjustable continuously, accuracy of measurement is high.In addition, be butted on product one side inwall by support bracket fastened static probe, the test rod of the dial gauge on traversing carriage is butted on product opposite side inwall, the internal diameter of product can be detected, because of the test rod of static probe and dial gauge little to the ergometry of product inwall, even detect the thin product internal diameter of wall, distortion can not occur to measure yet.
After described link mandrel is inserted in sleeve fully, test rod and the spacing between the static probe on fixed support of dial gauge are 65-75mm, and the sliding distance of link mandrel is 0-60mm.Because test rod and the spacing between the static probe on fixed support of dial gauge is 65-75mm, inner diameter measuring device of the present utility model so at least can be measured the product that internal diameter is 65-75mm.Simultaneously, the sliding distance of link mandrel is 0-60mm, and by the slip of link mandrel, inner diameter measuring device of the present utility model like this can detect the product that internal diameter is 65-135mm, and sensing range is large.
Described sleeve lining is provided with gathering sill, and the corresponding gathering sill in slip mandrel surface is provided with guide rod, and by guide rod, the gathering sill along sleeve horizontally slips the slip mandrel.The slip mandrel can be easily slides along the gathering sill of sleeve by guide rod.
The gathering sill of described sleeve lining is dovetail groove or straight trough.
Inner diameter measuring device of the present utility model is simple in structure, and production cost is low.Drive traversing carriage by link mandrel and slide, can measure the product of different inner diameters size, measurement range is large, and this adjusting operation is convenient, and adjustable continuously, accuracy of measurement is high.In addition, because the test rod of the static probe on fixed support and the dial gauge on traversing carriage is little to the ergometry of product inwall, even detect the thin product internal diameter of wall, distortion can not occur to measure yet.
