Full-automatic numerical control drilling machine for brake pad steel backing and power head assembly used in full-automatic numerical control drilling machine

Abstract

The invention belongs to the technical field of numerical control drilling machines and relates to a full-automatic numerical control drilling machine for a brake pad steel backing and a power head assembly used in the full-automatic numerical control drilling machine. The full-automatic numerical control drilling machine comprises a rack assembly, a power head assembly, a station assembly, a binassembly, a three-axis positioning robot hand and an electric control system. Under the dispatching of the electric control system, the rack assembly, the power head assembly, the station assembly, the bin assembly and the three-axis positioning robot hand can be used for conducting high-precision and high-efficiency drilling on a top hole of an arc face of the brake pad steel backing automatically and continuously, and the obvious effects that the labor intensity is low and the application range is wide are achieved. By means of the full-automatic numerical control drilling machine for the brake pad steel backing and the power head assembly used in the full-automatic numerical control drilling machine, the linear distance between a front power head and a rear power head can be adjusted through a bidirectional screw rod module, the drilling angle of the front power head and the rear power head can also be adjusted correspondingly through a front electric indexing plate and a rear electric indexing plate, the parameter regulating range is wide, applicability is high, automatic drilling work of various types of brake pad steel discs on the current market can be completed, automatic machining of the top hole of the arc face of the brake pad steel backing is achieved, the market vacancy is filled up, and industry development is promoted.

Description

technical field [0001] The invention belongs to the technical field of numerical control drilling machines, and in particular relates to a full-automatic numerical control drilling machine with a steel back for brake pads and a power head assembly used therein. Background technique [0002] The steel back is an important part used to fix the friction material on the automobile brake pad. The main structure is generally close to the fan surface; there are several assembly holes for positioning and fixing the friction material or brake pad on the large plane of the fan main body and the arc surface of the fan top. In the prior art, the steel back blank is generally used as the base material, and a manual drilling machine or a numerical control drilling machine is used to complete the processing of the assembly holes. However, since there is no machine tool dedicated to processing the steel backs of brake pads on the market, the clamping and positioning of the steel backs and t...

AI Technical Summary

Problems solved by technology

However, since there is no machine tool dedicated to processing the steel backs of brake pads on the market, the clamping and positioning of the steel backs and the processing of the assembly holes on the arc surface of the fan top all have problems in accuracy and efficiency; when manufacturers produce the steel backs of brake pads, they must Even if a CNC drilling machine is used, manpower must be used to complete the positioning and loading and unloading of the workpiece, and neither the machining accuracy nor the machining efficiency can meet the requirements.
