Drilling device for brake pad steel backing

Abstract

The present invention relates to a drilling device for a brake pad steel backing, comprising a plurality of drilling assemblies and a tightening mechanism, wherein the drilling assemblies are connected with a first driving mechanism, the first driving mechanism is capable of driving the adjacent drilling assemblies move towards or against each other; the drilling assemblies comprise a slewing mechanism connected with the first driving mechanism, the slewing mechanism is connected with a drilling bit assembly for driving rotation of the drilling bit assembly; the drilling bit assembly comprisesa drilling bit, and a second driving mechanism connected with the drilling bit, the second driving mechanism is fixedly connected with the slewing mechanism for driving the rotation of the drilling bit around the drilling bit axis and the feeding movement along the drilling bit axis. The tightening mechanism is arranged on one side of the drilling assemblies, comprising a third driving mechanism,and a tightening member connected with the third driving mechanism, the third driving mechanism is capable of driving the tightening member to tighten the brake pad steel backing to be drilled. The drilling device disclosed by the present invention has the beneficial effects of reducing the processing cost of the brake pad steel backing, thereby greatly reducing time for tool bit alignment.

Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to a brake pad steel back drilling device. Background technique [0002] The steel back of the brake pad and the friction material are composed of the brake pad through heat bonding technology, which is mainly used in the braking system of the car. The steel back is a fan-shaped carbon steel sheet, and usually two holes with a diameter of 2 or 2.5 mm need to be symmetrically drilled on the fan-shaped arc surface as the installation holes for the friction limiter. Due to the large number of car models, there are many varieties and specifications of the matching brake pads. The steel backs of each brake pad have different shapes, and the positions and angles of the processing holes are different. At present, the existing drilling equipment for the steel back of the brake pad usually adopts the fixed mold method, and each steel back needs to make a special positioni...
