Problems solved by technology

[0002] In the traditional way of stretching the skin, the power source of the stretching is the jack or the screw rotation. The disadvantage is that the structure is heavy, and the skin is in the stretching direction, and the force is uneven, which is easy to cause deformation of the skin and affect the skin. The smoothness of the appearance of the bus does not reach the expected effect

Abstract

The invention relates to the field of coaches, in particular to a novel skin stretching device. The novel skin stretching device at least comprises a rectangular frame structure, wherein the rectangular frame structure is formed by two positioning shafts and two frame beams. The novel skin stretching device is characterized in that two sliding sleeves are respectively and fixedly connected with both ends of a sliding rod, and the two sliding sleeves are respectively in sliding connection with the two positioning shafts of the rectangular frame; linkage cylinders are fixedly arranged on one frame beam, and the power output ends of the linkage cylinders are fixedly connected with the sliding rod; and the sliding rod is connected with a connecting plate by bolts. Because the expansion amount of the linkage cylinders are the same, the problem of skin deformation caused by uneven stress of skin in a stretching direction is solved; the connecting plate is connected with the sliding rod together by the bolts, and both surfaces of the connecting plate can be reused for many times, so that the use rate of equipment is increased; and additionally, after the connecting plate is used to a certain degree, the connecting plate can be easily replaced.

Description

technical field [0001] The invention relates to the field of passenger cars, in particular to a novel skin tensioning device. Background technique [0002] In the traditional way of stretching the skin, the power source of the stretching is the jack or the screw rotation. The disadvantage is that the structure is heavy, and the skin is in the stretching direction, and the force is uneven, which is easy to cause deformation of the skin and affect the skin. The smoothness of the appearance of the passenger car cannot reach the expected effect. Contents of the invention [0003] The purpose of the present invention is to provide a new type of skin stretching device with simple structure, uniform stress on the skin in the stretching direction, and not easy to cause deformation of the skin, so as to ensure the smoothness of the appearance of the passenger car. [0004] The technical solution adopted by the present invention to solve the technical problem is: a new type of skin...
