Summary of the invention:
Object of the present invention is exactly for the expensive shortcoming of current photoelectricity cubing, the symmetry degree gauge of a kind of physical construction provided.
In order to realize technique scheme, present invention employs following technical scheme:
A kind of vehicle rear-axle housing steel prop hole and main reducing gear mounting hole symmetry degree gauge, is characterized in that comprising:
A, base plate, for having certain thickness rectangular base plate;
B, base plate centre position arrange a base, base are arranged a positioning disk concentric with base, base are arranged chamfered edge pin and coordinate with positioning disk, to be located by vehicle rear-axle housing, make main reducing gear mounting hole center line consistent with the center line of positioning disk;
C, base plate centre position arrange one with the main reducing gear mounting hole measurement mechanism of positioning disk corresponding matching, as reference measurement device, on base plate positioning disk center line both sides relevant position on a moveable rear axle housing steel prop hole measurement mechanism is set respectively.
On the basis of technique scheme, there is following further technical scheme:
Described main reducing gear mounting hole measurement mechanism comprises: a mounting hole measuring seat be connected with base plate, and its top is provided with reference measurement rod and aims at main reducing gear mounting hole, and mounting hole measuring seat bottom has origin reference location pin to coordinate with base plate.
Described rear axle housing steel prop hole measurement mechanism comprises: a steel prop hole measuring seat, its top is provided with the steel prop hole measuring stick pointing to steel prop hole, be provided with gag and parallels below steel prop hole measuring seat successively and by screw, they be connected as a single entity, base plate is respectively equipped with twice T-slot with steel prop hole measuring seat correspondence position, two T-shaped bolts are respectively equipped with in each T-slot, then each T-shaped bolt uses wing nut locking positioning after being each passed through parallels, gag and steel prop hole measuring seat.
Arrange a feather key bottom described parallels, the gathering sill that feather key and base plate are arranged is slidably matched.
The invention has the advantages that: first use fixing main reducing gear mounting hole measuring stick determination workpiece spindle to central point, steel prop hole measuring stick on the steel holder measuring seat that recycling can be slided at base plate determines the center of tapping prop hole respectively, finally using universal check tool (vernier caliper or ruler) to measure tapping holder center and the distance A subtracted between shell mounting hole and B respectively, is the symmetry of steel prop hole and two steel prop holes by 1/2nd values of the absolute value of A-B difference; A+B and value are the distance of two steel holders.Measurement mechanism provided by the invention have structure simple, easy to use, measure accurate, cheap advantage.
