Abstract

The invention discloses a drum brake and hub static balance testing device and solves the technical problems of complex operation and low test efficiency of the test device of the conventional equipment. The device comprises a bracket (5) and bearings (7), wherein horizontal main shaft (6) is arranged in the two bearings (7); both ends of the main shaft (6) extend to the outer side of the bracket(5); the left end of the main shaft (6) is fixedly connected with a rotating disc (18), a flange plate (2) and a chuck (1) which is connected with a tested drum brake; the right end part of the main shaft (6) is movably sleeved with a measuring rod (14); the middle part of the measuring rod (14) is fixed at the right end of the main shaft (6) by a pressing bolt (12); and one end of the measuring rod (14) is provided with a counterweight (11), while the other end is provided with a balance weight (13). The device provides an accurate test method for the casting uniformity of the blank of the automotive drum brake.

Description

technical field [0001] The invention relates to a balance detection device for large castings, in particular to a static balance detection device for circular casting workpieces, such as brake drums, wheel hubs, brake discs and spoke wheel casting blanks of automobiles. Background technique [0002] The existing static balance detection devices are rail-type static balancer and roller-type static balancer. Firstly, the workpiece is placed on the balancer and rotated gently until the center of mass is at the lowest position. The direction is added to correct the balance mass, and then rotate again, and the balance mass is repeatedly increased or decreased until it is in a state of random balance, that is, the rotor reaches static balance. The prior art has the disadvantages of cumbersome clamping of workpieces and complex operation of counterweights. Contents of the invention [0003] The static balance detection device of the brake drum and the wheel hub provided by the i...
