Non-equal-thickness drum brake pad outer arc grinding production line with automatic feeding and discharging functions

Abstract

The invention relates to a non-equal-thickness drum brake pad outer arc grinding production line with automatic feeding and discharging functions. The production line comprises a feeding device, a positioning feeding device, a grinding device and an automatic discharging device, wherein the feeding device is used for adjusting the thick surfaces of brake pads to the same side and transmitting thebrake pads to the positioning feeding device; the feeding device comprises oppositely-arranged feeding side plates, the feeding side plates are provided with thickness detection devices, and the thickness detection devices are used for detecting the thick surfaces of the brake pads, a blocking cylinder, a lifting cylinder and a rotating cylinder are further arranged between the feeding side plates, the blocking cylinder is used for controlling the positions of the brake pads, the lifting cylinder drives the rotating cylinder, and the rotating cylinder is used for driving the brake pads to rotate; and the positioning feeding device is used for positioning the brake pads transmitted by the feeding device and feeding the brake pads to grinding stations. The production line can grind the outerarc of a non-equal-thickness drum brake pad, can realize the automatic feeding and discharging functions, and is suitable for large-scale assembly line work.

Description

technical field [0001] The invention relates to the field of friction lining processing equipment, in particular to an outer arc grinding production line for non-equal-thickness drum brake linings with automatic feeding and discharging. Background technique [0002] In the braking system of a car, the brake pads play a decisive role in the braking effect. With the development of economy and industry, the number of automobiles increases, and brake pads are wearing parts in the process of automobile driving, which need regular maintenance and replacement, so the demand for brake pads is also increasing. The brake pads are relatively rough after hot pressing, and the outer dimensions of the brake pads need to be ground. Since the brake pads have different product specifications of equal thickness and non-uniform thickness, the brake pads are manually adjusted when processing non-equal thickness brake pads. The brake pads are placed on the grinding machine, and the outer arc gr...

AI Technical Summary

Problems solved by technology

The brake pads are relatively rough after hot pressing, and the outer dimensions of the brake pads need to be ground. Since the brake pads have different product specifications of equal thickness and non-equal thickness, the brake pads are manually adjusted when processing non-equal thickness brake pads. The brake pads are placed on the grinding machine, and the outer arc grinding of the brake pads is mostly a single machine, with low automation level, high labor intensity and low production efficiency.

In addition, the existing brake pad grinding machines still have the disadvantages of inaccurate positioning, low grinding precision, and prone to defective products
