Abstract
The utility model discloses a micrometer-type inner diameter measurement gauge comprising an arch handle, wherein measurement rods are inserted on two ends of the arch handle from inside to outside and are rod-like bodies with head parts being larger than rod parts; the measurement rods comprise a left measurement rod and a right measurement rod; the left measurement rod is screwed with a nut outside the arch handle to fix; an adjusting nut is screwed on the right measurement rod; and pins are inserted on the head parts of the two measurement rods in an upright direction vertical to the arch handle. The right measurement rod is locked by a locking bolt and a fastening bolt stretching through lateral sides. The measurement gauge has the advantages that the structure is simple, the operation is simple and concise and the size control is accurate; the shape of the measurement gauge is similar to a micrometer, the middle position is vacated, interferences caused by an intermediate mandrel in the space are avoided when the measurement gauge is in use, and the measurement gauge is suitable for measuring an inner hole of a workpiece, wherein other parts or facilities are arranged at the centre of the workpiece.
Description
Technical field
The utility model relates generally to a kind of cubing structural design for measuring, and specifically a kind of have a milscale contour structures, carries out the cubing structural design that internal diameter size is measured.
Background technology
In actual production, when when horizontal lathe is processed round piece with the turning of mandrel class frock, the inner stopper of workpiece is measured because mandrel is in workpiece centre, can not directly measure with vernier caliper, measure with common clamp, owing to reasons such as operating personnel's operation technique, clamp degrees of tightness, the dimensional measurement inconvenient operation, DATA REASONING is inaccurate.Deviation often appears in the workpiece processing dimension, and qualification rate is low, needs again clamping to do over again, and working (machining) efficiency is very low.Equally, measuring center is during with the inner hole of workpiece of other parts or facility, and size is difficult to measure accurately.
The utility model content
The utility model purpose provides a kind of inner diameter measurement check tool, and it includes the contour structures of milscale, can carry out easily the measurement of internal diameter size, improves qualification rate and the effect of product.
The utility model is achieved through the following technical solutions:
A kind of milscale formula inner diameter measurement check tool, include arc handle, described arc handle two ends from inside to outside are inserted with sounding rod, described sounding rod is that head is greater than the rhabodoid of bar section, described sounding rod is divided into left sounding rod and right sounding rod, described left sounding rod is combined with nut in the outside of arc handle and is fixed, and described right sounding rod screws a setting nut thereon, and the head of described two sounding rods upwards is being inserted with pin perpendicular to arc handle vertical cube.
Lock-screw and holding screw that described right sounding rod stretches into by the side carry out position locking.
The utility model has the advantages that:
Cubing is simple in structure, and shape is similar to milscale, vacates the centre position, avoids in use aerial because of interfering with middle mandrel; Cubing simple to operation, size Control is accurate; Improved and used cubing to carry out qualification rate and the effect of endoporus size detection product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure synoptic diagram of the present utility model.
Embodiment
As illustrated in fig. 1 and 2, a kind of milscale formula inner diameter measurement check tool, include arc handle 2, described arc handle 2 two ends from inside to outside are inserted with sounding rod, described sounding rod be head greater than the rhabodoid of bar section, described sounding rod is divided into left sounding rod 3 and right sounding rod 5, described left sounding rod 3 is combined with nut 1 in the outside of arc handle 2 and is fixed, described right sounding rod 5 screws a setting nut 6 thereon, and the head of described two sounding rods upwards is being inserted with pin 4 perpendicular to arc handle vertical cube.Lock-screw 7 and holding screw 8 that described right sounding rod 5 stretches into by the side carry out position locking.
Cubing cooperates the pin on the sounding rod when measuring with the workpiece seam, the adjusting setting nut finds the tightness that cooperates of the full-size of workpiece seam and pin 4 and seam, after adjusting, locks set nut 7.Take out cubing, according to the precision of dimensional measurement, select vernier caliper or outside micrometer to measure two sizes of measuring between the lever pin 4, so just can accurately obtain the processing dimension of workpiece seam.
Claims (2)
1. milscale formula inner diameter measurement check tool, it is characterized in that: include arc handle, described arc handle two ends from inside to outside are inserted with sounding rod, described sounding rod is that head is greater than the rhabodoid of bar section, described sounding rod is divided into left sounding rod and right sounding rod, described left sounding rod is combined with nut in the outside of arc handle and is fixed, and described right sounding rod screws a setting nut thereon, and the head of described two sounding rods upwards is being inserted with pin perpendicular to arc handle vertical cube.
