Embodiment
Below in conjunction with accompanying drawing,, the present invention is further elaborated by describing a preferable specific embodiment in detail.
As shown in Figure 2, a kind of compressor connecting bar parallelism measuring instrument comprises mobile jib and regulates parts 1, secondary bar 2, indicating device, fixed component and positioning element; Described mobile jib is regulated the positioning rod 12 that parts 1 comprise mobile jib 11, link to each other with mobile jib 11; Described positioning rod 12 is provided with measures immovable point projection 121.
Described secondary bar 2 one ends are inserted in the mobile jib 11, and its other end extension is arranged on outside the mobile jib 11, and links to each other with indicating device, and secondary bar 2 can slide up and down along mobile jib 11.
Described fixed component is several retaining screws 41, its be arranged on the mobile jib 11 and with the joint of secondary bar 2, after the length adjustment in the secondary bar 2 insertion mobile jibs 11 finishes, described plurality of fixed screw 41 passes mobile jib 11 and holds out against the outer surface of secondary bar 2, makes secondary bar 2 be fixed on the position in the current insertion mobile jib 11.
The indication pole 32 that described indicating device comprises dial indicator 31, links to each other with secondary bar 2; Described dial indicator 31 is arranged on the indication pole 32.The measurement immovable point projection 121 of the gauge outfit of dial indicator 31 and positioning rod 12 is on the same installation axis.
