Special brake drum clamp capable of improving product percent of pass and using method thereof

Abstract

The invention discloses a special brake drum clamp capable of improving the product percent of pass and a using method thereof. According to the clamp, the outer surface of the upper end of a clamp body is provided with a first fixed station, the outer surface of the upper end of the first fixed station is provided with a fixed outer ring, the inner wall of the fixed outer ring is provided with a movable ring in a sleeving mode, the inner wall of the movable ring is provided with a movable clamping rod in a sleeving mode, a limiting head is arranged on the outer surface of one side of the movable clamping rod, a second fixed station is installed at one end of the fixed outer ring, an anti-deviation ring is installed on the outer surface of the upper end of the second fixed station, and a butt joint block is arranged on the outer surface of the other side of the movable clamping rod. According to the special brake drum clamp capable of improving the product percent of pass and the using method thereof, arranged fan-shaped clamping plates are used for clamping the outer wall of a to-be-machined brake drum, arranged clamping heads are used for clamping the inner wall of the to-be-machined brake drum, the to-be-machined brake drum is prevented from shaking during machining, and good using prospects are brought.

Description

technical field [0001] The invention relates to the technical field of brake drum manufacturing, in particular to a special clamp for brake drums capable of improving the qualified rate of products and a using method thereof. Background technique [0002] The brake drum is a cast iron piece similar to a tambourine. It is fixed with the tire and rotates at the same speed. When braking, the brake shoe is pushed by oil pressure to contact the inner edge of the brake drum. The friction generated by the contact inhibits the rotation of the tire to achieve braking. Purpose, the drum brake is composed of the brake base plate, the brake cylinder, the brake shoe and other related connecting rods, springs, pins, and brake drums. At present, it is only commonly used in the rear wheel. It is higher and is widely used in the rear wheels of small cars, but its wear rate is higher, so the overall cost is higher. [0003] Due to its special purpose and operating environment, military speci...

Problems solved by technology

The commonly used material for brake drums is HT250 gray cast iron. Generally, defects such as cracks, slag inclusions, and pores are not allowed after casting. If there are brake drum blanks with more hard points, it is more difficult to machine, which requires Choosing a more suitable processing technology and cutting tool has brought certain adverse effects on people's use process. In order to solve the problems existing in the manufacturing process of brake drums for military special vehicles, we propose a special brake drum that can improve the product qualification rate.
