Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 2 and Figure 3, a kind of measurer structure for the dimensional measurement of plunger member skewed slot, comprise chassis 1, on chassis 1, arrange respectively measuring unit and positioning unit, the structure of measuring unit is as follows: comprise traveller seat 7, traveller 5 passes through lining ring 12 through-going devices in traveller seat 7, be positioned at traveller seat 7, be set with the first Compress Spring 13 in the periphery of traveller 5, the measuring junction butt of one end of traveller 5 and dial gauge 2, dial gauge 2 is fixing by chuck 3 and milled screw 4, and the other end connects swing arm 14, and the end that is positioned at swing arm 14 extends to form flange 9; Described flange 9 is cylindrical, and the diameter of flange 9 is directly proportional to the spacing of the skewed slot 102 of plunger member 101.
The structure of positioning unit is as follows:
Comprise location saddle 8, on locating piece 8, have " V " shape groove.Be positioned at one end of locating piece 8, the flat position of returning apparatus positioning unit on described chassis 1, is positioned at the other end of locating piece 8, returning apparatus fore-set seat 11 on chassis 1, and the end of fore-set seat 11 extends to form fore-set 10;
The structure of described flat position positioning unit is as follows:
Comprise flat position post 6, the spring location-plate 15 that is embedded in 1 inside, chassis and locating sleeve 19, the end of spring location-plate 15 connects flexible locating piece 17 by the second Compress Spring 16, and the end of flexible locating piece 17 extends to form boss 18.
Concrete use procedure of the present invention is as follows:
First carry out the processing of the skewed slot 102 of plunger member 101, then the bus of learning skewed slot 102 in plunger member 101 by product drawing to the margin tolerance of the distance L 1 of end face at ± 0.05mm, , then a plunger member that processes skewed slot is sent to measuring room, measure the value A of L1 by universal tool microscope, then by the first value of being adjusted to A of dial gauge 2, again this plunger member 101 is put into the present invention, first plunger member 101 is placed in locating piece 8 " V " shape groove, then the flat position of plunger member 101 is connected with boss 18, boss 18 is connected with the flat position of plunger member 101 by the contractility of the second Compress Spring 16 all the time, one end and fore-set 10 butts of plunger member 101 simultaneously, positioning datum and accuracy that plunger member 101 is measured are guaranteed thus.Then by traveller 5, moving around in traveller seat 7 is adjusted to correct position, be rocked to skewed slot 102 places of plunger member 101 by swing arm 14, until in flange 9 interlockings and this skewed slot 102, the now end butt of the other end of traveller 5 and dial gauge 2 make dial gauge 2 show numerical value B, then judge that whether difference between B numerical value and A numerical value is at qualified margin tolerance ± 0.05mm, after measurement completes, swing arm 14 is upwards overturn, take out plunger member 101, with this measurement that circulates, effectively realize the measurement of plunger member skewed slot size in enormous quantities.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
