Be equipped with the calibrated scale on the axle sleeve outer peripheral face, fix and rotating epaxial pointer and the corresponding setting of calibrated scale. Be equipped with the gag lever post in the axis of rotation, the gag lever post corresponds the setting with the spacing screw of spiro union on the axle sleeve. The utility model discloses when measuring starter steel brush spring, install the utility model discloses on starter steel brush spring be close the actual using -way of this spring, the data of measuring are more accurate.

Description

Starter wire brush spring dynamometer

Technical field

The utility model relates to spring force survey instrument, particularly starter wire brush spring dynamometer.

Background technology

After starter wire brush spring machines, need the torsion measuring starter wire brush spring, guarantee that starter wire brush spring meets the quality requirements in use.Equipment due to current starter wire brush spring torsional test mostly is tautness meter and detects, and equipment is relatively simple and crude coarse, and accurately can not control starter wire brush spring windup-degree and contacting points position, metrical error is bigger than normal; Because reviewer's detection method is different, the starter wire brush spring torsion measured is accurate not, and complicated operation, causes testing efficiency not high.

Summary of the invention

The technical matters that the utility model solves is to provide that a kind of measuring accuracy is high, method of operating is simple, improve the starter wire brush spring dynamometer of testing efficiency.

Technical solutions of the utility model complete like this, starter wire brush spring dynamometer, include base, also include steady sensor, rotation axis, display, rotation axis is rotatably connected in the axle sleeve that is fixed on base, one end of rotation axis is fixed with and the crotch in starter wire brush spring inner ring can be made to overlap superincumbent erection column, and turning handle is fixed on the other end of rotation axis; The LOAD CELLS be located at below erection column is fixed on base, and LOAD CELLS is connected with the display be located on base.

Further preferred embodiment, described axle sleeve outer peripheral face is provided with index dial, fixing pointer setting corresponding with index dial on the rotating shaft.

Further preferred embodiment, described rotation axis is provided with gag lever post, and gag lever post is corresponding with the limited screw be screwed onto on axle sleeve to be arranged.

Further preferred embodiment, one end of rotation axis is tubulose, and erection column is fixed on the rotation axis of tubulose.

During owing to measuring starter wire brush spring with the utility model, be arranged on the actual use-pattern of the starter wire brush spring on the utility model close to this spring, the data measured are more accurate.Because this spring attachment positions is fixed, under gag lever post and limited screw are worked in coordination, make windup-degree during test start machine wire spring consistent, effectively can improve the testing efficiency with batch starter wire spring.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail, base 6 is installed with LOAD CELLS 3, display 1, axle sleeve 4, the LOAD CELLS 3 be located at below erection column 2 is connected with display 1, is rotatably connected to rotation axis 9 in axle sleeve 4, and rotation axis 9 one end is tubulose; The rotation axis 9 that erection column 2 is enclosed within tubulose is interior and fixing with screw 12; Erection column 2 will be set as and match with the crotch 14 in starter wire brush spring inner ring to be measured, the starter wire brush spring crotch 14 be enclosed within erection column 2 can not be rotated, can only follow rotation axis 9 and rotate together; Turning handle 11 is arranged on the other end of rotation axis 9.

For the starter wire brush spring windup-degree accurately controlling to be located on erection column 2 can be made, axle sleeve 4 outer peripheral face is provided with index dial 5, is fixed on pointer 10 setting corresponding with index dial 5 on rotation axis 9.

For detection can be made consistent with batch starter wire brush spring windup-degree be located on erection column 2, rotation axis 11 is provided with gag lever post 12, and gag lever post 12 is corresponding with the limited screw 7 be screwed onto on axle sleeve to be arranged.During rotation, the limited screw 7 of gag lever post 12 blocks, thus the angle that rotation axis 11 rotates is constant, conveniently can detects like this and play the spring torsion size of col machine wire spring under same windup-degree with batch same model, thus accurately can grasp the quality condition of this batch of starter wire brush spring.

When measuring starter wire brush spring 13, the crotch 14 of starter wire brush spring 13 is enclosed within erection column 2, starter wire brush spring end 15 is placed on above LOAD CELLS 3, rotary motion handle 11 makes rotation axis 9 rotate, starter wire brush spring end 15 is stressed presses down LOAD CELLS 3, and starter wire brush spring torsion can be presented on the display screen 8 of display 1 by sensor 3.
