The invention provides an airtightness detection platform for a steering-engine casing. The detection platform includes an end-part plugging air cylinder, a leakage detector, a display, a work piece middle bracing frame, a work piece end part bracing frame and a work piece corner bracing frame. The end-part plugging air cylinder is horizontally installed at one end of the detection platform and a piston rod of a work piece pressing air cylinder is installed at the other end of the detection platform in a vertical upward manner. A left plugging air cylinder and a right plugging air cylinder are located at the left and right sides of the detection platform respectively. The work piece middle bracing frame is installed between piston rods of the left and right plugging air cylinders. The work piece corner bracing frame is installed on the detection platform at the side of the work piece pressing air cylinder and the other side of the work piece corner bracing frame is provided with the work piece end part bracing frame. One side of the detection platform is provided with the leakage detector and the top part of the leakage detector is provided with the display. The detection platform is simple in structure, accurate in detection data and high in detection efficiency.
Description
technical field [0001] The invention relates to the technical field of steering gear, in particular to an airtight detection platform for a steering gear housing. Background technique [0002] With the vigorous development of the automobile industry, the total number of automobiles in the world is constantly increasing, and more and more people use automobiles as a means of transportation and transportation. The performance of automobiles is directly related to personal safety, especially the performance of automobile steering systems. Good or bad, it affects the driver's driving comfort, driving stability and driving reliability. The steering gear is one of the important parts of the steering system. When the driver turns the steering wheel, it helps the driver to use force to reduce the driver's effort when steering. , A machine that achieves the purpose of ease and convenience for the driver when driving. Mainly divided into rack and pinion steering and worm gear steerin...
