Detailed description of the invention

As shown in accompanying drawing 1, accompanying drawing 2, a kind of slide measure of measuring part chamfering, is made up of main scale 1, secondary chi 2, fixing measuring jaw 3, movable measuring jaw 4, two polygon gauge blocks 7, screw 6, alignment pin 5 etc. Described fixing measuring jaw 3 is made one with main scale 1, on main scale 1, has scale; Movable measuring jaw 4 is made one with secondary chi 2, on secondary chi 2, has vernier 8, and secondary chi 2 can slide on main scale 1, and number reading method when measurement is the same with general slide measure.

As shown in Figure 3, on described fixed amount measuring jaw 3 and movable measuring jaw 4, all have a semi-circular recesses, in the inner side of the semi-circular recesses of fixing measuring jaw 3 and movable measuring jaw 4, have respectively one with the supporting plane of above-mentioned groove center in same plane.

As shown in Figure 4, described polygon gauge block 7 is polygonized structure, and edge is by 73 3, the measurement limit straight flange of the 72 and 60 ° of chamferings in measurement limit of 71, the 45 ° of chamferings in measurement limit of 30 ° of chamferings, and two sections of circular arc compositions. The end points of above-mentioned three straight flanges and two sections of circular arcs, be all positioned on same circle. In the center of this circle, three pin-and-holes that have a centre bore and distribute centered by this hole, three pin-and-holes are corresponding with the measurement limit of 30 degree chamferings, 45 degree chamferings and 60 degree chamferings respectively. While measuring chamfering, by two polygon gauge blocks 7, use screw 6 and alignment pin 5, be arranged on respectively in the groove of movable measuring jaw 4 and fixing measuring jaw 3.

The utility model is positioned at the measurement limit on the polygon gauge block of fixing measuring jaw groove, will form an intersection point with the supporting plane on fixing measuring jaw, and this intersection point is corresponding to the dead-center position on main scale; Be positioned at the measurement limit on the polygon gauge block of movable measuring jaw groove, form an intersection point with the supporting plane on movable measuring jaw, this intersection point is corresponding to the dead-center position on secondary chi. In the time measuring chamfering, the supporting plane of fixing measuring jaw and movable measuring jaw is leaned against in the upper plane of workpiece, the measurement limit of polygon gauge block leans against on the fillet surface of workpiece. Now the vertex position of chamfering work piece will be captured accurately, and corresponding to the vernier size dead-center position on size zero point and secondary chi on the utility model main scale, thereby can read exactly the size on chamfering top.

To measure 30 ° of chamferings as example explanation: as shown in Figure 5, two polygon gauge blocks 7 are installed on respectively in the semi-circular recesses on fixing measuring jaw 3 and movable measuring jaw 4. When installation by polygon gauge block 7 with 30 ° of pin-and-holes that bevel edge is corresponding, aim at alignment pin 5 in semi-circular recesses and tighten fixing with screw 6. The 30 degree chamferings that are now positioned on the polygon gauge block 7 of fixing the half slot on measuring jaw 3 and movable measuring jaw 4 are measured limits, with the intersection point of supporting plane, corresponding to the dead-center position on main scale and secondary chi. When measurement, by the supporting plane of movable measuring jaw 4 and fixing measuring jaw 3, lean against wish and survey on the upper transverse plane of chamfering, moving sets chi 2 makes the degree of 30 on polygon gauge block 7 chamfering measure limit, leans against on the fillet surface of tested chamfering, reads the size L on chamfering top.

As shown in accompanying drawing 6, accompanying drawing 7, the method for measuring 45 ° of chamferings and 60 ° of chamferings is identical with the method for measuring 30 ° of chamferings.
