Abstract
The utility model relates to a detection tool for degree of symmetry between automobile rear axle housing steel holder holes and a main speed reducer mounting hole. The detection tool comprises a base plate (1). A pedestal (5) is disposed in the center of the base plate. The pedestal is provided with a positioning disk (3) that is concentric with the pedestal (5). The pedestal (5) is also provided with an edge cutting pin (4) that matches the positioning disk. The base plate (1) is equipped with a measuring stand (19) and a reference measuring rod (20). A steel holder hole measuring stand (8) and a steel holder hole measuring rod (13) are arranged at a corresponding position on each of two sides of a central line of the positioning disk (3) on the base plate (1). The steel holder hole measuring stands (8) on the two sides are moved to allow the steel holder hole measuring rods (13) to be smoothly inserted into steel holder holes (2b), thereby truly measuring positions of the steel holder holes. A universal measuring tool (such as a vernier caliper or a ruler) can be adopted to measure a distance A and a distance B between the two steel holder holes and a main speed reducer positioning hole, and according to state specified standards, a half of an absolute value of A minus B is the degree of symmetry between the two steel holder holes and a value of A plus B equals a distance between two steel holders. The detection tool provided by the utility model has the advantages of simple structure, convenience in use, accurate measurement and low price.

C, base plate centre position arrange a main reducing gear mounting hole measurement mechanism with the positioning disk corresponding matching, as the reference measurement device, a movably rear axle housing steel prop hole measurement mechanism are set respectively on the relevant position of positioning disk center line both sides on the base plate.
On the basis of technique scheme, following further technical scheme is arranged:
Described main reducing gear mounting hole measurement mechanism comprises: a mounting hole measuring seat that is connected with base plate, its top are provided with the reference measurement rod and aim at the main reducing gear mounting hole, and mounting hole measuring seat bottom has the origin reference location pin to cooperate 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 of pointing to the steel prop hole, be provided with successively gag and parallels below the steel prop hole measuring seat and by screw they be connected as a single entity, be respectively equipped with the T-shaped groove of twice with steel prop hole measuring seat correspondence position on the base plate, be respectively equipped with two T-shaped bolts in each T-shaped groove, then each T-shaped bolt uses the wing nut locking positioning after passing respectively parallels, gag and steel prop hole measuring seat.
Described parallels bottom arranges a feather key, and the gathering sill that arranges on feather key and the base plate is slidingly matched.
The utility model has the advantage of:
Determine that with fixing main reducing gear mounting hole measuring stick workpiece spindle is to central point first, recycling can the steel prop hole measuring stick on the steel holder measuring seat that base plate slides be determined respectively the center of tapping prop hole, using at last universal check tool (vernier caliper or ruler) to measure respectively tapping holder center and subtract distance A and B between the shell mounting hole, is the symmetries of steel prop hole and two steel prop holes with 1/2nd values of the absolute value of A-B difference; A+B and value are the distance of two steel holders.That the measurement mechanism that the utility model provides has is simple in structure, easy to use, measure accurate, cheap advantage.
