[0001] The utility model relates to the technical field of automobile parts processing, and specifically relates to a brake pad slotter with dust suction device. BACKGROUND

[0002] The automobile brake pad is also called automobile brake pad, which is fixed on the brake drum or brake disc. The friction material, including the friction pad and the friction block, bears external pressure and generates friction to achieve the purpose of vehicle speed reduction. The automobile brake pad is generally composed of a steel plate, an adhesive heat insulation layer and a friction block. During braking, the brake pad is pressed on the brake disc and generates friction with the brake disc to achieve the purpose of vehicle speed reduction and braking. In the brake system of the automobile, the brake pad is the most critical safety part, and the brake effect is determined by the brake pad. Generally, in order to ensure the performance of the brake pad, a slotting process is performed on the friction block of the brake pad during processing and use, which can better improve the friction coefficient and drainage effect, and effectively dredge the dust during friction to avoid the problem of brake effect reduction caused by the existence of the brake pad and the brake disc. However, during the slotting process of the brake pad, a large amount of waste and dust will be generated, which will splash and damage the equipment and harm the health of the operators. Therefore, a dust suction device is generally provided on the brake pad slotting device. In the dust removal device for brake pad production with the patent number CN208695898U and the name of a kind of brake pad production, a box is used for dust suction. Although the dust suction device can prevent the waste and dust from splashing and can better collect the waste and dust, it occupies a large space and is not convenient to use. In addition, it needs to use an additional fan for collection, which consumes a large amount of energy. CONTENT OF THE UTILITY MODEL
