Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figures 1 to 6, the utility model includes bracket 1, support plate 2, adapter assembly 3, blocking arm component 4, balancing pole 5 and weight tray 17.It is as shown in Figure 1 that the bottom of bracket 1 is equipped with levelling shoe 6()；Support plate 2 is fixed on 1 upper end edge of bracket Position, plate face are vertical；One through-hole 201 is arranged at the top of support plate 2, respectively there is a vertical chute 202 on the two sides of support plate 2 (as shown in Figure 2)；Blocking arm component 4 includes U-shaped sliding panel 13 and the railing (as shown in Figure 3) being mounted on U-shaped sliding panel 13, U-shaped sliding panel 13 is sleeved in support plate 2 and cooperates with the vertical chute 202, and blocking arm component 4 can be in support plate 2 along two sides The vertical chute 202 slides up and down (as shown in Figure 1)；Adapter assembly 3 includes outer sleeve 10, inner sleeve 12, expansion sleeve 11 and bearing 9, bearing 9 is fixedly mounted on the outer wall of outer sleeve 10, and inner sleeve 12 is coaxially connected in outer sleeve 10 by expansion sleeve 11, outside The external end head of sleeve 10 and inner sleeve 12 respectively has a square opening (as shown in Figure 5 and Figure 6), and adapter assembly 3 passes through the fixed peace of bearing 9 In the through-hole 201 of support plate 2 (as shown in Figure 1)；The centre bit of balancing pole 5 is equipped with a square tenon 501, and weight tray 17 is hung Mounted in the end (as shown in Figure 4) of 5 side lever arm of balancing pole, balancing pole 5 is inserted into the square opening of inner sleeve 12 by square tenon 501 In.

In the present embodiment, the rectangular plate 7(that 1 upper end of bracket is provided with a horizontality is as shown in Figure 1)；Support plate 2 Medium position be vertically and fixedly provided with a transverse slat 8, transverse slat 8 and support plate 2 are T-shaped structure (as shown in Figure 2)；Transverse slat 8 with Rectangular plate 7 is bonded fixed (as shown in Figure 1).Before detection, first passes through stabilizer blade 6 and level rectangular plate 7.

As shown in figure 3, railing includes two upright bars 14 and a cross bar 15 in the present embodiment, two intervals of upright bar 14 are solid It is scheduled in the top planes of U-shaped sliding panel 13, cross bar 15 is movably arranged on the upper end of two upright bars 14；U-shaped sliding panel 13 A lock-screw 16 is respectively equipped on two side plates, the position of lock-screw 16 corresponds to the vertical chute 202 in support plate 2 (as shown in Figure 1).

The construction features of adapter assembly 3 are explained as follows below:

It is fixedly mounted on due to bearing 9 on the outer wall of outer sleeve 10, bearing 9 is fixedly mounted on the through-hole 201 of support plate 2 In, therefore outer sleeve 10 is rotary relative to through-hole 201.Expansion sleeve 11 is to be mounted on outer sleeve 10 by bolt 11-1 On, when unclamping bolt 11-1, inner sleeve 12 and outer sleeve 10 are in loosening state, both can be rotated, inner sleeve 12 may be used also With the axial displacement in outer sleeve 10.When tightening bolt 11-1, inner sleeve 12 and the relative position of outer sleeve 10 can be fixed.This The design of sample is to make adapter assembly 3 when examining and determine tested plank 19, and the angle of 10 end square opening of outer sleeve can adapt to pull The angle state of square tenon at hand.

In calibrating, first have to guarantee that tested plank 19 is in plumbness, while balancing pole 5 is adjusted to horizontal State.Therefore, before tested plank 19 is installed, expansion sleeve 11 is first unclamped, inner sleeve 12 and outer sleeve 10 is made to be in loosening state, Then tested plank 19 is installed.Installing tested plank 19 is that square tenon on tested 19 driving end of plank is first inserted into 10 end of outer sleeve It in head square opening, allows tested plank 19 to be in nature vertical state, while fixing its tail portion, then rotates inner sleeve 12, make to balance Bar 5 is in horizontality, finally tightens expansion sleeve 11.

The tail portion fixation of tested plank 19 is implemented by arm of force component 4.Outside the head of tested plank 19 is plugged on After in 10 end square opening of sleeve, tail portion is located at naturally between two upright bars 14, adjusts the upper bottom of U-shaped sliding panel 13 at this time It sets and passes through lock-screw 16 and lock it in support plate 2, then cross bar 15 is inserted into two upright bars 14, Board Under Test The tail portion of son 19 compresses.

In detection process, gives tested plank 19 and apply torsional forces F1, the length of the half of arm of force of balancing pole 5 is L, counterweight The gravity of pallet 17 is G, and calculating counterbalance mass to be loaded accordingly is N=F1/L-G, and counterweight 18 needed for calculating is put into counterweight On pallet 17, the torque indicating value of tested spanner 19 can be read after 17 natural stability of weight tray, so that it is determined that tested pull The error amount of son.The detection data of multiple test points can be obtained by replacing counterweight 18, the inspection of indicating value style torque spanner can be completed It is fixed, and then it can be calibrated.
