Background technology
The mark of chamfering on workpiece, comprises the diameter of the angle value of chamfering and the length of side of chamfering or chamfering. The angle value of chamfering can use general angle block gauge to measure; The measurement of the length of side of chamfering or the diameter of chamfering, has two kinds of methods conventionally: the one, use general vernier caliper measurement, and the 2nd, use gauge block is made with the special angle Special caliper of measured workpiece angle equal angular and measured. But these two kinds of methods all exist shortcomings and limitations: the shortcoming of general slide measure is the summit of the gauge block misalignment chamfering work piece of slide calliper rule, cannot Measurement accuracy reading; The weak point of special angle Special caliper is the chamfering angle size that a special angle Special caliper can only be measured a kind of angle.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, manufactures simply, and easy to operate, service-strong is measured the slide measure of part chamfering.
The technical scheme in the invention for solving the above technical problem is: a kind of slide measure of measurement chamfering, formed by main scale, secondary chi, fixing measuring jaw, movable measuring jaw, two polygon gauge blocks, screw, alignment pins, it is characterized in that: described fixing measuring jaw and main scale are made one, have scale on main scale; Movable measuring jaw and secondary chi are made one, have vernier and can on main scale, slide on secondary chi; On described fixing measuring jaw and movable measuring jaw, all have a semi-circular recesses, in the inner side of the semi-circular recesses of fixing measuring jaw and movable measuring jaw, have respectively one with the supporting plane of above-mentioned groove center in same plane; In described semi-circular recesses, have a screw and a dowel hole, screw is positioned at the center of semi-circular recesses; Described polygon gauge block is arranged on respectively in the semi-circular recesses of movable measuring jaw and fixing measuring jaw by screw and alignment pin.
Described polygon gauge block is polygonized structure, and the edge of gauge block is made up of three straight flanges and two sections of circular arcs, the measurement limit that described three straight flanges are respectively 30 °, 45 ° and 60 ° chamferings; Article three, the end points of straight flange and two sections of circular arcs are all positioned on same circle, three pin-and-holes that have in the heart a centre bore and distribute centered by this hole in this circle, and three pin-and-holes are corresponding with the measurement limit of 30 °, 45 ° and 60 ° chamferings respectively; Measure when chamfering polygon gauge block by the centre bore on gauge block and the pin-and-hole of answering in contrast, use screw and alignment pin, be arranged on respectively in the groove of movable measuring jaw and fixing measuring jaw.
The utility model, in the time measuring chamfering, leans against the supporting plane of fixing measuring jaw and movable measuring jaw in the upper plane of workpiece, and 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. The utility model, by adjusting the position of gauge block, can be measured 30 °, 45 ° and 60 ° of chamferings, and against existing technologies, it is rational in infrastructure, manufactures simply, and easy to operate, use is reliable, accomplishes that a chi is multiplex.

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.
