Embodiment Construction
[0017] The present invention will be described in further detail below by means of specific embodiments:
[0018] The reference signs in the accompanying drawings include: height gauge 1, base 2, cylinder 21, push plate 22, water bag 23, frame 3, flow channel 31, through hole 32, hydraulic cylinder 33, positioning rod 34, push rod 35, support block 36, cylinder head 4.
[0019] Such as figure 1 As shown, the engine cylinder head valve position detection device includes a base 2, a mobile lifting unit, a fixed unit, and a height gauge 1 for detecting cylinder head 4 valves. The height gauge 1 is located on the left side of the fixed unit, and the height gauge 1 is slidably connected. On the base 2, the position of the height gauge 1 can be adjusted when the cylinder head 4 is detected. The mobile rising unit includes a cylinder 21, a push cylinder, a water bag 23 and a positioning plate for fixing the water bag 23. The positioning plate is fixed on one side of the water bag 2...

The invention belongs to the technical field of metering devices characterized by adopting a mechanical method, and specifically discloses an engine cylinder head valve location degree detection device. The detection device comprises a base, a moving ascending unit, a fixed unit and a height gauge; the moving ascending unit comprises a cylinder, a water bag, a locating plate and a pressing plate, and push plates are arranged on a piston rod of the cylinder and a surface groove of the water bag; the fixed unit comprises a frame, a hydraulic cylinder, a support block and a locating rod, a runner and a through hole are formed in the frame, and the locating rod is connected with the through hole in a slide mode; the water bag is arranged at one side of the frame and communicated with one end of the runner, the other end of the runner is communicated with the hydraulic cylinder; a piston rod of the hydraulic cylinder is connected with a push rod in a hinged mode; the locating rod comprises a cone portion and a cylindrical portion connected with the cone portion, the cylindrical portion comprises an inner core, a spring and an elastic layer from inside to outside successively, the spring is connected between the inner core and the elastic layer. By adoption of the engine cylinder head valve location degree detection device, the cylinder head valve location degree is detected accurately, and meanwhile, the problem is solved that the work intensity of lifting and fixing of the cylinder head is large.
Description
technical field [0001] The invention belongs to the technical field of metering equipment characterized by adopting mechanical methods, and in particular relates to an engine cylinder head valve position detection device. Background technique [0002] At present, in the machining of automobile engine cylinder heads, there are more valves (more double-camshaft cylinder heads), and various errors in casting or processing cylinder heads will cause large deviations in the position of individual valves, resulting in cylinder heads during engine assembly. The accuracy of the position matched with the cylinder block is too low, and even directly affects the efficiency of the internal combustion engine of the engine, so it is necessary to detect the valve position of the cylinder head. The traditional cylinder head valve position detection method only detects a single position, which is not only low in detection efficiency, but also prone to large cumulative errors, and cannot guara...
