Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of swing arm threaded hole arrangement for measuring verticality, and this swing arm threaded hole arrangement for measuring verticality has advantages of that clamping is easy, detection error is little and detection efficiency is high, and does not detect blind spot.
For achieving the above object, the utility model provides following technical scheme:
A kind of swing arm threaded hole arrangement for measuring verticality, comprise the locating shaft coordinating with swing arm threaded hole, on described locating shaft, be equiped with positioning disk with its rotation engage sleeves, the lower surface of described positioning disk is provided with the probe coordinating for contacting with rocking arm reference field, be positioned on the locating shaft of described positioning disk top dial gauge is installed, the probe of described dial gauge contacts cooperation with the upper surface of described positioning disk, the upper surface of described positioning disk is vertical with the axis of described locating shaft, and described locating shaft is provided with for driving described probe to remain and contacts the elastic body coordinating with rocking arm reference field.
Further, described dial gauge bias is arranged on described locating shaft, and between described locating shaft and described dial gauge, is provided with for by the fixing fixture of clamping on locating shaft of dial gauge.
Further, described elastic body comprises and is arranged between described fixture and described positioning disk and is sleeved on the spring on described locating shaft.
Further, described locating shaft is provided with the two thread segments that coordinate with swing arm threaded hole, and described pair of thread segment comprises two sections of screw threads that link together.
Further, the periphery wall of described positioning disk is provided with angle index.
The beneficial effects of the utility model are:
Swing arm threaded hole arrangement for measuring verticality of the present utility model, during use, coordinates locating shaft with swing arm threaded hole, locking screw central diameter, under the effect of elastic body, probe contacts cooperation with rocking arm reference field, in addition, the probe of dial gauge and the upper surface of positioning disk contact cooperation; Rotation positioning disk, if there is the error of perpendicularity between swing arm threaded hole and rocking arm reference field, so under the effect of elastic body, positioning disk also can moving axially along locating shaft, and read moving range by dial gauge, and then draw the verticality between swing arm threaded hole and rocking arm reference field; Therefore, swing arm threaded hole arrangement for measuring verticality of the present utility model has advantages of that clamping is easy, detection error is little and detection efficiency is high, and does not detect blind spot.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is the structural representation of existing a kind of rocking arm tool for detecting screw perpendicularity;
Fig. 2 is the structural representation of the utility model swing arm threaded hole arrangement for measuring verticality embodiment;
Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 2, be the structural representation of the utility model swing arm threaded hole arrangement for measuring verticality embodiment.The swing arm threaded hole arrangement for measuring verticality of the present embodiment, comprise the locating shaft 2 coordinating with rocking arm 1 threaded hole, on locating shaft 2, be equiped with positioning disk 3 with its rotation engage sleeves, the lower surface of positioning disk 3 is provided with the probe 4 coordinating for contacting with rocking arm 1 reference field A, be positioned on the locating shaft 2 of positioning disk 3 tops dial gauge 5 is installed, the probe of dial gauge 5 contacts cooperation with the upper surface of positioning disk 3, the upper surface of positioning disk 3 is vertical with the axis of locating shaft 2, and locating shaft 2 is provided with the elastic body that contacts cooperation for driving probe 4 to remain with rocking arm 1 reference field A.
The swing arm threaded hole arrangement for measuring verticality of the present embodiment, during use, coordinates locating shaft 2 with rocking arm 1 threaded hole, locking screw central diameter, under the effect of elastic body, probe 4 contacts cooperation with rocking arm reference field A, in addition, the probe of dial gauge 5 contacts cooperation with the upper surface of positioning disk 3; Rotation positioning disk 3, if there is the error of perpendicularity between rocking arm 1 threaded hole and rocking arm reference field A, so under the effect of elastic body, positioning disk 3 also can moving axially along locating shaft 2, and read moving range by dial gauge 5, and then draw the verticality between swing arm threaded hole and rocking arm reference field A; Therefore, the swing arm threaded hole arrangement for measuring verticality of the present embodiment has advantages of that clamping is easy, detection error is little and detection efficiency is high, and does not detect blind spot
