Description

Technical Field

[0001] The utility model relates to the field of preparing a hydraulic oil cylinder for automobile moulds, in particular to a cylinder barrel positioning device for preparing a hydraulic oil cylinder for automobile moulds. Background Art

[0002] The most important component of automobile molds is the cover mold. This type of mold is mainly a cold stamping mold. In a broad sense, automobile molds are the general term for molds for manufacturing all parts of automobiles. For example, stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc. No matter what kind of automobile mold, it is inseparable from the hydraulic cylinder. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] After the existing hydraulic cylinder is positioned in the cylinder barrel, the piston, piston rod and buffer device are installed based on the cylinder barrel. Therefore, the positioning of the cylinder barrel is particularly important. If there is an error in the positioning of the cylinder barrel, there will be a series of interlocking errors in the installation of accessories such as the piston, piston rod and buffer device in the later stage. The existing cylinder barrel is generally placed on a positioning base plate by hoisting, and then the cylinder barrel is positioned by manual positioning. During the positioning process, the axis of the cylinder barrel needs to be aligned with the center of the positioning base plate so that the piston, piston rod and other accessories can be installed smoothly, efficiently and accurately. However, when there is an error in the positioning of the cylinder barrel, it is necessary to manually hoist and translate it for parallelization and adjustment, which is time-consuming and labor-intensive and it is difficult to ensure the positioning accuracy of the cylinder barrel, which is very inconvenient.
