Described measurement its front end external diameter of table dop is Morse's taper quartering elastomer, with the minor diameter fit that locking nut locks instrument, rear end and left measuring unit.
Described left measuring unit external diameter one end is screw-like, it is connected with locking nut, end face and measurement table chuck end contact, internal diameter front end coordinates with measuring table dop, middle part is equipped with meter support bar, bar is measured in elastic instrument contact stem, spring and grooving, and external diameter is provided with the cam measurement apparatus equal with groove width at middle part.
Described grooving is measured bar upper end and is combined with first measuring unit one end internal diameter, and bar is measured in described grooving and the first measuring unit passes through bonded, moves along a straight line；Upper end is cylindrical in left measuring unit internal diameter, and end face withstands in elastic instrument contact stem, and cylindrical end is fixed together with right measuring unit equipped with stage clip, lower end, and it is exactly to measure the position that bar moves that right measuring unit cam enters the deviation post of grooving.
Described second measuring unit internal diameter measures bar major diameter fit with grooving, and the second measuring unit external diameter has two screwed holes, is bolted on grooving and measures on bar identical with the first measuring unit external diameter, and the second measuring unit is provided with the cam measurement apparatus equal with groove width.
The work process of the present invention is as follows: with slide calliper rule or meet grooving position dimension standard sample circle adjust measurement standard, adjust the position of the first measuring unit, with bolt, the first measuring unit is fixed on measurement bar, adjusts instrument spring contact bar, make gauge pointer to 0, then the cam of the first measuring unit is measured foot and puts into a processing groove, place into right measurement cam and measure foot, start to measure, the plus-minus difference on table, it is exactly the position difference of grooving, such that it is able to measure processing groove location accurately.
It is an advantage of the current invention that: due to internal channel measuring instrument Technology application, making the interior slot value that cannot measure, can measure smoothly, measuring speed can improve more than 10 times, and certainty of measurement is the most accurate.

Detailed description of the invention
For understanding internal channel measuring instrument in depth, it is described as follows in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7:
Internal channel measuring instrument divides three parts, instrument portion, standing part and dynamic part, instrument portion is mainly dial gauge, including the display instrument of numerical value, meter support bar, instrument spring contact bar, meter support bar is arranged in the card lobe internal diameter of measurement table dop 2, measure 4 sets by locking nut 1 with first to be fixed together, holddown spring 3, instrument spring contact bar 8, measurement bar the 5, second measuring unit 6 link together, and belong to dynamic part, can record grooving size；
nullPrinciple of surveying: see Fig. 1 product grooving structure，Its operation principle of internal channel measuring instrument is the width according to workpiece product grooving、The degree of depth，First the positioning cam of the first measuring unit 4 is processed，Reprocess the second measuring unit 6 and measure cam，Length processing length according to product grooving suitably measures bar 5，Locking nut 1 is fixed together with the first measuring unit 4，Holddown spring 3、Measure bar 5 to load in the first measuring unit 4，With slide calliper rule or meet grooving position dimension standard sample circle adjust measurement standard，Adjust the position of the first measuring unit 4，Bolt is utilized to be fixed on by the first measuring unit 4 on measurement bar 5 after meeting size，Adjust instrument spring contact bar 8，Make gauge pointer to 0，Then the cam of left measuring unit is measured foot and puts into a processing groove，Place into right measurement cam and measure foot，Start to measure，Plus-minus difference on table，It it is exactly the position difference of grooving，Such that it is able to measure processing groove location accurately.
