When the elastic side bearing body is used, the mouth part of the bowl-shaped body faces downwards, so that the plane corresponding to the bottom of the bowl-shaped body is the upper plane of the elastic side bearing body. When the elastic side bearing body of the truck locomotive is processed, the side inclined surface 3 needs to be drilled. The general positioning mechanism of ordinary lathe can not fix a position the elasticity side bearing body. In the prior art, a numerical control locomotive is adopted to drill the side inclined surface 3 of the elastic side bearing body, and the processing cost is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an elasticity side bearing side inclined plane drilling positioning fixture, the processing cost who adopts this positioning fixture is lower.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses an elasticity side bearing side inclined plane drilling positioning fixture's characteristics are including the bottom plate, have the backup pad that the slope was arranged on the bottom plate, and the acute angle between backup pad and bottom plate is the same with the angle between elasticity side bearing side inclined plane and upper surface. The screw rod is fixed on one side of the supporting plate corresponding to the obtuse angle formed by the supporting plate and the bottom plate, the screw rod is perpendicular to the supporting plate, connecting strips are arranged on two sides of the side plate above the screw rod, a limiting rod horizontally arranged is fixed on the inner side face of one connecting strip, the limiting rod is parallel to the supporting plate, a threaded hole horizontally arranged is formed in the other connecting strip, a jacking bolt is arranged in the threaded hole and is parallel to the supporting plate, and the jacking bolt and the limiting rod are located on one side of the supporting plate corresponding to the screw rod. The top of the supporting plate is provided with a guide plate which is horizontally arranged, the guide plate is provided with a guide hole, and the guide hole is positioned on one side of the supporting plate corresponding to the screw rod.
And reinforcing ribs are arranged between one side of the supporting plate corresponding to an acute angle formed by the supporting plate and the bottom plate, and the reinforcing ribs are vertically arranged.
By adopting the scheme, the method has the following advantages:
because the utility model discloses an elasticity side bearing side inclined plane drilling positioning fixture's including the bottom plate, there is the backup pad on the bottom plate, and backup pad one side are fixed with the screw rod, and the screw rod is perpendicular with the backup pad, all has the connecting strip on the curb plate both sides of screw rod top, is fixed with the gag lever post that the level was arranged on the medial surface of one of them connecting strip, has the screw hole that the level was arranged on another connecting strip, has the puller bolt in the screw hole, has the deflector that the level was arranged at the top of backup pad, has the guiding hole on the deflector. When the clamp is manufactured, the position of the guide hole is obtained by reversely pushing according to the position of the side inclined plane through hole of the elastic side bearing. When in use, the positioning clamp is arranged at a corresponding position of the bedplate of the machine tool through the bottom plate. When the device works, the upper plane of the elastic side bearing body is abutted against one side of the supporting plate corresponding to the screw rod, a bowl-shaped body of the elastic side bearing body is sleeved on the screw rod, and one side of the elastic side bearing body is abutted against the limiting rod; then, adjusting a puller bolt, and fixing the elastic side bearing body between the puller bolt and the limiting rod, wherein the upper plane of the elastic side bearing body is abutted against one side of the support plate corresponding to the screw rod, and the acute angle between the support plate and the bottom plate is the same as the angle between the side inclined plane and the upper surface of the elastic side bearing body, so that the side inclined plane of the elastic side bearing body is in a horizontal state; and finally, starting the movable machine tool to drill the side inclined plane of the elastic side bearing through the guide hole. After the elastic side bearing body is fixed by the fixture, the side inclined surface of the elastic side bearing body is in a horizontal state and can be machined by a common machine tool, so that the machining cost is greatly reduced.
