Background

For the pre-welding assembly process of the cylinder bottom of the hydraulic cylinder, two problems mainly exist in hoisting and positioning the position of the cylinder bottom in a traditional mode. Firstly, in the traditional cylinder bottom hoisting process, a hoisting rope is directly tied on the cylinder bottom for hoisting, and the cylinder bottom is difficult to horizontally place on a tool under the action of self weight; secondly, the traditional three-jaw chuck cannot clamp a flat cylinder bottom; the existing solution is to change the three-jaw chuck into a symmetrical two-jaw chuck, and the problem that the cylinder bottom is difficult to position is solved although the cylinder bottom can be clamped, an operator needs to adjust the cylinder bottom position to ensure the coaxiality of the cylinder bottom and the cylinder barrel assembly, the whole process is time-consuming and labor-consuming, and the moving of the cylinder bottom position on the jaws has great danger.

Through searching, the technical scheme of the hydraulic cylinder bottom welding fixture is found to be close to the technical scheme of the utility model, the mandrel is clamped in the middle of the chuck and is fixedly connected with one end of the L-shaped support, the other horizontal end of the L-shaped support is provided with a base plate, the base plate is used for supporting the cylinder bottom lining to prevent the cylinder bottom from being displaced in the horizontal direction, an inner hole of the base plate is provided with a fixed shaft, the cylinder bottom can be placed on the base plate through the fixed shaft, the upper end of the base plate is fixed on the cylinder bottom through the locking piece and the pressing plate, the cylinder bottom and the mandrel are guaranteed to be at the same horizontal height, and coaxiality of the cylinder bottom and a cylinder barrel assembly can be guaranteed. However, the technical scheme does not optimize the lifting process of the cylinder bottom, and when the cylinder bottoms with different specifications are welded, the whole set of tools such as the mandrel, the L-shaped bracket and the like are required to be replaced, and only the matched cylinder bottom sleeve is required to be replaced in the utility model.

Because the backing plate excircle of cylinder bottom cover is transition fit with the side of cylinder bottom hole in order to restrict the displacement of cylinder bottom in the horizontal direction, can constantly rub at hoist and mount cylinder bottom cover in-process both, and the backing plate that can lead to the cylinder bottom cover is worn and torn for a long time, needs to in time change the cylinder bottom cover of wearing and tearing, this also can increase frock cost.
