Embodiment
According to embodiment and accompanying drawing the utility model is described in further detail below.
Shown in Fig. 1 to 8, a kind of appliance special for detecting of measuring the connecting rod 8 concentric reducer hole depth of parallelisms comprises major part cylinder check rod 1, microcephaly's cylinder check rod 2, " V " type left socle 3, adjustable " V " type right support 4, fore-stock 5, height gauge 6 and lever meter 7; The external diameter of described major part cylinder check rod 1 matches with connecting rod 8 big end hole internal diameters to be measured, and major part cylinder check rod 1 can insert in connecting rod 8 big end holes; The external diameter of described microcephaly's cylinder check rod 2 matches with connecting rod 8 microcephaly hole internal diameters to be measured, and microcephaly's cylinder check rod 2 can insert in the connecting rod 8 microcephaly holes; Described major part cylinder check rod 1 is set up on described " V " type left socle 3, adjustable " V " type right support 4; Described microcephaly's cylinder check rod 2 can be set up on the transportable preceding back-up block 5; Described lever meter 7 is arranged on the height gauge 6, and can move up and down along height gauge 6.
The course of work of the present utility model is as follows:
Shown in Fig. 1 to 8, tested connecting rod 8 big end holes are penetrated major part cylinder check rod 1, make measured connecting rod 8 place the middle part of major part cylinder check rod 1 as far as possible; Again the two ends that penetrate the major part cylinder check rod 1 behind the connecting rod 8, put into respectively on the left socle 3 that is placed in advance on the platform, the V-type groove on the right support 4; When major part cylinder check rod level is not contour, can adjusts the height of adjustable " V " type right support 4 and realize contour; Adjust the level height of major part cylinder check rod 1, till level is contour; After treating that major part cylinder check rod 1 is adjusted to level, microcephaly's cylinder check rod 2 is penetrated in the microcephaly hole of tested connecting rod 8 again, and the exposed length at microcephaly's cylinder check rod 2 two ends that penetrate connecting rod 8 microcephaly holes is equated as far as possible; Because the depth of parallelism in connecting rod 8 concentric reducer holes is divided into the microcephaly hole to big end hole horizontal direction parallel degree and two indexs of the vertical direction depth of parallelism,, measurement carries out so also will dividing two:
