[0002] The tightness between the booster and the vacuum tube of the car is very high, and it is usually achieved by the interference fit and wedge-shaped structure of the vacuum tube joint and the seal ring of the booster housing. This structure is reliable but the pull-out force is very large. Maintenance of vacuum boosters Or when replacing the vacuum tube, the two need to be separated. The material of the vacuum tube joint is made of plastic. Uneven force may cause the joint to break when it is disassembled. The broken end must be taken out.

At present, there is no special removal tool. During the process of repairing and removing the vacuum tube, the broken end often cannot be taken out or falls into the cavity of the booster. In addition to removing the associated parts of the front cabin and brake exhaust, it is time-consuming and labor-intensive, which increases the maintenance cost

Embodiment Construction
[0016] see figure 1 It can be seen that the broken end removal tool includes an operating rod 1, a power shaft 2, a hand nut 3, a circumferential limit pin 4, a pull rod 5, an expansion head 6 and a wedge ring 7, wherein the operating rod 1 is a tubular structure with an expansion head at one end 6. The other end is provided with a hand tightening nut 3. The expansion head 6 is composed of a fixed connection end and an expansion end. The fixed connection end is provided with an external thread for threaded connection with the operating rod 1 and is easy to replace. The expansion end consists of three or four petals. Elastic curved surface can expand under pressure to increase the outer diameter. The power shaft 2 is a cylinder with an outer diameter smaller than the inner diameter of the operating rod 1, and is placed inside the operating rod 1. One end of the threaded section protrudes from the operating rod 1 and is screwed with the hand nut 3, and the other end is connected...

The invention discloses a method and a tool for taking out a broken end of a brake vacuum tube. According to the method for taking out the vacuum broken end of the brake, the broken end is clamped by using a tool; the broken end is pushed into a cavity of a vacuum booster casing so as to prevent the broken end to fall into the cavity; a sealing ring is taken down by using a clearance between the tool and the sealing ring; then the tool is taken out and the broken end is taken down; and finally, the sealing ring is placed to the original position. According to the tool and the method, the vacuum tube can be quickly removed so as to prevent the residue of the broken end and time and labor saving are achieved; and meanwhile, the phenomenon that the reliability of a brake system is reduced caused by unnecessary removal of the booster is avoided.
Description
technical field [0001] The invention relates to a dismantling method of auto parts and a dismantling tool thereof, more specifically, to a method for taking out a broken end of an automobile booster housing and a brake vacuum tube and a tool for taking out a broken end by using the method. Background technique [0002] The tightness between the booster and the vacuum tube of the car is very high, and it is usually achieved by the interference fit and wedge-shaped structure of the vacuum tube joint and the seal ring of the booster housing. This structure is reliable but the pull-out force is very large. Maintenance of vacuum boosters Or when replacing the vacuum tube, the two need to be separated. The material of the vacuum tube joint is made of plastic. Uneven force may cause the joint to break when it is disassembled. The broken end must be taken out. If it falls into the cavity, the booster will fail and the brake pedal will be heavy. And a series of high-risk failures suc...
