Description

Automobile nylon pipe strength detection equipment Technical Field The utility model relates to the field of detection equipment, in particular to automobile nylon tube strength detection equipment. Background The nylon pipe for automobile is one kind of engineering plastic pipe with nylon as main material and through extrusion or casting process, and has the features of light weight, wear resistance, corrosion resistance, high impact resistance, high flexibility, etc. In the automotive field, nylon pipes are widely used in fuel oil, braking, cooling and air conditioning systems, and are rapidly connected through cold plugging or laser welding processes, so that the nylon pipes can adapt to the high-temperature environment of an engine compartment, can be flexibly bent to optimize the space layout, and become an ideal scheme for replacing metal and rubber pipelines. In the prior art, in the actual assembly process of an automobile, a nylon pipe is required to be subjected to a series of operations such as laying, bending and fixing, and the operations inevitably exert a certain tensile force on the nylon pipe. If the tensile strength of the nylon pipe cannot meet the requirements, the nylon pipe is extremely easy to break, damage or deform in the installation process, so that the normal installation and connection of a pipeline system are affected, and the overall performance of the automobile is adversely affected. Therefore, accurate detection of the tensile strength of the nylon pipe of the automobile is important, and a tensile testing machine becomes indispensable equipment in the detection process. However, the current automotive nylon tube is of a wide variety of tube diameter specifications, covering various types from small tubules to larger diameter tubing. When the nylon pipes with different pipe diameters are used for detecting the tensile strength, different requirements are met on the clamping force and the contact area of the clamp. The existing tensile testing machine is generally provided with the same set of clamp, and is difficult to provide ideal clamping effect for nylon pipes with different pipe diameters. Specifically, for nylon pipes with smaller pipe diameters, the large-size clamp can cause uneven distribution of clamping force and overlarge local pressure so as to damage the nylon pipes, while for nylon pipes with larger pipe diameters, the small-size clamp cannot provide enough clamping force, so that a sliding phenomenon is easy to occur in the stretching process, and the accuracy of test results is seriously affected. In order to ensure the reliability of the test, a proper clamp must be replaced in time according to the pipe diameter of the nylon pipe. Currently, most clamps used in tensile testing machines are fixed by bolting. The connection mode has obvious defects when stretching resistance detection is carried out on the automobile nylon pipes with different diameters. Because the dismouting is changed the complex operation, needs to consume a large amount of time and energy for the change process of anchor clamps can't accomplish fast, thereby greatly reduced the detection efficiency of car nylon pipe, be difficult to satisfy the demand of current car trade to spare part short-term test.
