The cross section of the inner hole at one end of the hollow telescopic rod is a taper; the center of the tapered block is provided with a screw hole and is positioned in the taper-shaped cross-sectional hole at one end of the hollow telescopic rod; the bottom of the movable clamping foot is provided with a through hole; the screw rod is arranged at one end of the handle; the screw rod traverses the through hole of the movable clamping foot and is screwingly arranged in the screw hole of the tapered block; and the vernier caliper is arranged at the other end of the hollow telescopic rod. According to the parallelism measuring tool, the distance between bearing pedestals with an ultra-long spacing is conveniently and accurately measured, connection pull bars are adjusted according to the measure data, and thereby the parallelism of the bearing pedestals satisfies the requirement, normal operation of equipment is guaranteed, and the quality of products is maintained.
Description
Technical field
The utility model relates to a kind of ultralong distance bearing seat measurement of paralleism instrument.
Background technology
Rolling mill for hot rolled planks and strips pinch roll on coiling machine two side shaft holder spacings are larger, and two bearing seat one sides adopt by articulated linkage connection, opposite side and connect the pull bar connection.In two bearing seat installation processes, need to adjust its depth of parallelism, to guarantee the normal operation of pinch roll.Usually in the depth of parallelism adjustment process, operating personnel at first adopt tape measure to measure respectively the spacing of two bearing seat articulated linkage sides and connection pull bar side, and according to the data of measuring, adjustment connects pull bar, so that the depth of parallelism of two bearing seats reaches requirement.
Obviously operating personnel are when using the tape measure spacing, choose and estimate the deviation that produces because measuring the end face location point, making the bearing seat both sides connect pull bar adjusted size precision is difficult to control, directly have influence on the parallelism precision of two side shaft holders assembling, both sides draught pressure deviation when causing the pinch roll operation, quality control brings impact on template.
Summary of the invention
Technical problem to be solved in the utility model is ultralong distance bearing seat measurement of paralleism instrument, utilize this survey instrument can make things convenient for, accurately record the spacing of ultralong distance bearing seat, connect pull bar so that the bearing seat depth of parallelism meets the demands according to measurement data by adjusting, guaranteed the normal operation of equipment and the quality of product.
For solving the problems of the technologies described above, the utility model ultralong distance bearing seat measurement of paralleism instrument comprises the hollow expansion link, handle, screw rod, movable card base, circular cone and vernier caliper, described hollow expansion link one end inner hole section is taper, described circular cone center is provided with screw and is positioned at the hole, tapered cross-section of described hollow expansion link one end, described active card foot bottom has through hole, described screw rod is located at described handle one end, described screw rod penetrates the through hole of described movable card base and twists in the screw of described circular cone, and described vernier caliper is located at the other end of described hollow expansion link.
Further, the junction pole face of above-mentioned expansion link is provided with the Length Indication scale.
Because the utility model ultralong distance bearing seat measurement of paralleism instrument has adopted technique scheme, be that this survey instrument comprises hollow expansion link, handle, screw rod, movable card base, circular cone and vernier caliper, hollow expansion link one end inner hole section is taper, the circular cone center is provided with screw and is positioned at the hole, tapered cross-section of hollow expansion link one end, the active card foot bottom has through hole, screw rod is located at handle one end, screw rod penetrates the through hole of movable card base and twists in the screw of circular cone, and vernier caliper is located at the other end of hollow expansion link.This survey instrument can make things convenient for, accurately record the spacing of ultralong distance bearing seat, connects pull bar so that the bearing seat depth of parallelism meets the demands according to measurement data by adjusting, and has guaranteed the normal operation of equipment and the quality of product.

Embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model ultralong distance bearing seat measurement of paralleism instrument comprises hollow expansion link 1, handle 2, screw rod 6, movable card base 3, circular cone 5 and vernier caliper 4, described hollow expansion link 1 one end inner hole sections are taper, described circular cone 5 centers are provided with screw and are positioned at the hole, tapered cross-section of described hollow expansion link 1 one ends, described movable card base 3 bottoms have through hole, described screw rod 6 is located at described handle 2 one ends, described screw rod 6 penetrates the through hole of described movable card base 3 and twists in the screw of described circular cone 5, and described vernier caliper 4 is located at the other end of described hollow expansion link 1.
Further, for ease of directly reading the length of expansion link, the junction pole face of above-mentioned expansion link 1 is provided with Length Indication scale 11.
As shown in Figure 4, when bearing seat 7 is installed the adjustment operation, determine the spacing dimension of two bearing seats 7 according to technological requirement, the articulated linkage 71 of two bearing seat 7 one sides is installed, adjust expansion link 1 length of this survey instrument according to the spacing dimension of two bearing seats 7, this length numerical value can conveniently obtain by the Length Indication scale 11 of expansion link 1 junction, then with the card base 41 of the movable card base 3 at this survey instrument expansion link 1 two ends and the vernier caliper 4 measurement end face 73 against two bearing seats 7, unscrew screw rod so that movable card base 3 can be done 360 degree rotations along axis by handle 2, by the rotation adjustment activity card base 3 of movable card base 3 and the surface of contact of bearing seat 7 measurement end faces 73, so that expansion link 1 is horizontal, tighten screw rod by handle 2 subsequently, screw rod drives circular cone and moves outside the hole, tapered cross-section of expansion link 1 one ends, thereby clamping activity card base 3, this survey instrument is fixed between the measurement end face 73 of two bearing seats 7, then records the interval error of two bearing seats 7 by the vernier caliper 4 of expansion link 1 other end.Vernier caliper 4 is connected with expansion link 1 other end, can make an axle sleeve at expansion link 1 other end endoporus, according to vernier caliper 4 face sizes, mills out flat groove at inner hole of shaft sleeve, then vernier caliper 4 is inserted in the flat groove of axle sleeve to be welded and fixed.Distance measurement can divide double measurement, and the record measurement data, obtains interval error.According to the interval error that records, adjust the connection pull bar 72 of two bearing seat 7 opposite sides, so that the interval error of two bearing seats 7 satisfies the requirement of the depth of parallelism, finish the installation of bearing seat and adjust operation.
