Specific embodiment
The following further describes the present invention with reference to the drawings:
As shown in Figures 1 to 4, a kind of inertia rotors detecting tool, which is characterized in that including tooling main body 01, and compress
Cap 03；Main body 01 is stepped cylinder, and lower end is chassis, and upper end center is equipped with two stage steps hole, two stage steps hole with main body 01
Rank cylinder is coaxial, and the small diameter portion of stepped hole is arranged with screw thread, and upper surface is parallel with lower chassis plane；Clamping cap 03 includes knob
Bar 031, disk 032, accurate guide post 033, threaded rod 034, clamping cap 03 is in the upper end step hole of main body 01, threaded rod
034 is threadedly coupled with the path part of stepped hole, and the bottom surface of disk 032 is bonded with 01 upper end face of main body, accurate guide post 033
Mounted in the large diameter portion of 01 stepped hole of main body, 1/3 of upper surface diameter less than inertia rotors basal diameter of main body 01 is greater than used
Property rotor center stepped hole hole diameter.
The large diameter portion clearance fit of accurate guide post 033 and 01 stepped hole of main body, fit clearance are 5-8 μm.
Tooling main body 01 is the mounting platform of inertia rotors, and have several different functional areas: lower end is chassis plane, is
Precision surface, plays the role of Z-direction centering, and the screw thread of stepped hole path part plays the role of the cap 03 that is fixed and clamped, two stage steps
The large diameter portion in hole is PRECISION HOLE in the top of stepped hole, plays inertia rotors installation guiding role, the upper end of tooling main body 01
Face is precision surface, is the installation supporting surface of inertia rotors.
Clamping cap 03 is the fastener of inertia rotors detecting tool, is made of 4 different functional areas: disk 032
Bottom surface is the compression using face of clamping cap 03, and 032 diameter of disk is greater than inertia rotors center stepped hole hole diameter, and used
Property rotor center macropore clearance fit, fit clearance 0.05-0.1mm.Accurate guide post 033 is played in the lower section of disk 032
The large diameter portion in the two stage steps hole of installation guiding role and tooling main body 01 is used cooperatively, and threaded rod 034 is in accurate guide post
033 lower section, plays fastening effect, and rotary knob rod 031 is the portion of the handle of clamping in the top part of clamping cap 03.
Working principle: the lower end bottom surface of tooling main body 01 is placed in detection platform, when clamping, the lower surface of inertia rotors
See the upper surface fitting of Fig. 1 and tooling main body 01, effective fit area is thin ring-shaped, selects the region as supporting surface, keeps away
Exempt from measuring machine and surveyed the collision of ball, while not reducing effective measuring area, cannot be eccentric after the fit area clamping, it is to pass through pressure
Tight cap 03 and guaranteed by the structure of tooling main body 01: the accurate guide post 033 of clamping cap 03 passes through the centre bore of inertia rotors
Into in the stepped hole of tooling main body 01, due to the large diameter portion clearance fit of accurate guide post 033 and 01 stepped hole of main body, match
Gap control is closed at 5-8 μm, in addition, stepped hole and 01 stepped cylinder of main body are coaxial, to guarantee that installing fit area does not fill partially
The heart.Fastening is realized by the stepped hole cooperation on the threaded rod 034 and tooling main body 01 on clamping cap 03, and threaded rod is worked as
032 bottom surface of disk and inertia rotors centre bore when on the 034 downward stepped hole screw thread for screwing in tooling main body 01, on clamping cap 03
Interior step is met personally Fig. 1 fitting and is compressed, which is thin ring-type, and effectively compression region is small, and the cylindrical surface of disk 032 and inertia turn
The cooperation of subcenter interporal lacuna, gap size controls in 0.05-0.1mm, to ensure that effective compression, avoids pressure tiltedly, simultaneously
Pressing force is uniform, carries out clamping to inertia rotors through the invention, picks up inertia rotors small arc surface measurement element point quasi-
Really, high-efficient, it is reproducible, it can relate, and clamping error is small, guarantee the precision of measuring machine sampling site.
Application method explanation:
The present invention solves the problems, such as the clamping before three coordinate measuring engine measurement, and specific clamping process is as follows:
The lower surface of inertia rotors is placed on the upper surface of tooling main body 01 by step 1.
Step 2, with hand steered firmly measured workpiece, clamping cap 03 is passed through the centre bore of inertia rotors, will compressed by another hand
Accurate guide post 033 on cap 03 is inserted into tooling main body stepped hole, rotatably compresses the rotary knob rod 031 of 03 top of cap, screw thread
Bar 034 is threaded into the threaded hole in the stepped hole in tooling main body 01, and until knob can not rotate, then clamping is completed.
