Embodiment
The utility model is mainly used in the measurement of axiality between two large diameter holes on heavy parts, is used as hand-held work
Tool can directly be used by operating personnel, on the basis of a datum hole, measure axiality of another measured hole to the datum hole.
With reference to the accompanying drawings and examples to it is described in the utility model for axiality detect hand-held tool make into
The elaboration of one step, but protection domain of the present utility model can not be limited with this.
Referring to Fig. 1, illustrate for axiality detect hand-held tool include support body 1, packing ring 3, the collar 4, support 6,
Chuck 8 and amesdial 7.
The support body 1 is played a supporting role as the main body of kit, and miscellaneous part is installed on the support body 1.Institute
State support body 1 to be welded using the light low density material of matter heavily fortified point amount, to meet hand-held requirement, while itself is to the accuracy of manufacture
It is less demanding, manufacturing cost is relatively low.Described support body 1 is a Step Shaft, and its top is provided with upper cylinder and lower cylinder, the support body
1 extend into datum hole and measured hole with axiality requirement, directly hand-held by operating personnel.
If the packing ring 3 is fixedly connected on the lower plane of the upper cylinder at the top of support body 1, and bottom by bolt stem 2
Face B is resisted against the upper plane of the datum hole；The external diameter of the packing ring 3 is more than the diameter of the datum hole.
The collar 4 is placed on the top of the support body 1 and positioned at the lower section of the packing ring 3, and the collar 4 is using cold
Set mode (i.e. first heating collar 4 be inserted in support body 1 cool down fixation again) banding in the support body 1 lower cylinder it is cylindrical on, the set
The outer peripheral face A of ring 4 matches with the inwall of the datum hole, forms gap and coordinates.
Packing ring 3 and the collar 4 both parts serve the positioning action of the hand-held tool, are to perform positioning to make
Main element.The outer peripheral face A of the bottom surface B of described packing ring 3 and the collar 4 needs after having perpendicularity requirement, installation
Carry out grinding machine finishing perpendicularity.The packing ring 3 and the collar 4 are changeable type simultaneously, can be according to the not people having the same aspiration and interest of different part datum holes
The diameter of the whole packing ring 3 and the collar 4 is to be changed.
The support 6 is a rod member, is connected to the lower end of the support body 1 along the radial direction of measured hole, the support 6 it is interior
