SU555001A1 - Vibration container for parts - Google Patents

Description

one

This invention relates to a vibration treatment technique.

Containers are known in which a device is fastened at a certain distance from its bottom, which is the individual sections in which the workpieces are placed.

For processing large-sized parts in a fixed state, containers containing freely moving support cradles and clamps holding the part are used.

However, to remove a part from the device in such containers, it is necessary to unload the working environment, which takes a significant amount of auxiliary time.

The purpose of the invention is to reduce the auxiliary time during the vibration treatment of parts by eliminating the loading and unloading operations of the working environment.

This goal is achieved by the fact that the support elements and clamps are installed on at least two pairs of hydraulic cylinder rods rigidly fixed in the container with the possibility of contact of the support-lodgements

and clamps through the part to be processed with vertical synchronous movement of the rods, with the upper cavity of one of the hydraulic cylinders of each pair associated with a pressure source, and the lower cavity of the other hydraulic cylinder with a capacity filled with liquid, which is located above the level of the hydraulic cylinders.

The drawing shows schematically a container in cross section, a general view.

Claims (2)

In the body 1 of the container is mounted on the rods 2 support lodgements 3, and on the rods 4 - clamps 5 with the possibility of their rotation around the axis of the rod. The rods 2 and 4 are mounted respectively on pistons x 6 and 7 of the hydraulic cylinders 8 and 9, which are rigidly connected to the housing 1. In the hydraulic cylinders 9 there are springs 10, which keep the rods 4 in an inoperative state in the upper position. The upper cavity of hydraulic cylinders 9 directly at the housing 1 is connected by a hydraulic line 11 with a source 12 of pressure, and the lower cavity of hydraulic cylinders 8 is connected by a hydraulic main 13 with an open container 14 filled with liquid, which is higher than the level of hydraulic cylinders. A valve 15 is installed in the hydraulic line 13 to periodically shut off the liquid from the tank 14 into the hydraulic cylinders 8 cavity. The hydraulic line 13 parallel to the valve 15 has a hydraulic valve 16 that allows fluid from the hydraulic cylinders 8 to flow into the container 14 only if a certain pressure is formed in the hydraulic cylinders 8. In the body 1 of the container on the support-lodgements 3 stack the item to be processed. The support-supports 3 are always above the working medium, as they are mounted on the rods 2 rigidly connected to the pistons, and those due to the pressure of the liquid column coming from the tank 14 through the hydraulic line 13 into the hydraulic cylinders 8 are always in the upper position Since the lodgements 3 in the housing 1 are somewhat different, the part to be processed is different in thickness, at the first moment it does not touch all the support lodgements 3, but only some of them. Having experienced additional pressure on the weight of the part, then no 6 will begin to descend until the detail touches all support-lodgments and each of them will not experience the distributed weight of the part. As soon as the part is laid, the valve 15 is closed: the liquid from the hydraulic cylinders 8 does not flow into the container 14. Then the clamp 5, together with the rod 4 and the piston 7, is turned in such a way that it is above the part. From the pressure source 12, along the hydraulic line 11, the hydraulic cylinders 9 supply sufficient pressure to clamp the part mounted on the cradle-supports by the clamps 5. The immersion of the part into the working medium proceeds as follows. The container attached to the vibratory machine (not shown in the drawing) is subjected to vibratory oscillations. The working medium in the container comes to a pseudo-liquefied state. By means of the pressure source 12, the hydraulic cylinders 9 create an overpressure. In hydraulic cylinders 8, the same pressure occurs. The valve 16 hydr line 13, having experienced the same overpressure, opens slightly. The fluid from the hydraulic cylinders 8 will begin to flow, the piston 6 simultaneously with the piston 7 will be lowered. As soon as the part is immersed in the working medium, the initial pressure is established by the source 12 in the hydraulic cylinders 9. In the hydraulic cylinders 8 the same pressure as in the hydraulic cylinders 9 is established. After treatment with a pressure source 12, pressure is relieved in hydraulic cylinders 9. At the same time, valve 15 of hydraulic line 13 is opened. Under the action of spring 10, current 4 is raised, and rod 2 together with lodgement 3 and the machined part is one above the working medium. Next, take 5 along with the rod 4 and the piston 7 turn around the axis: the part flush on the cradle is removed. Claims The container for vibro-processing of parts, containing freely moving support-cradles and clamps, fixing the part, different in that. . time reduction during vibration processing by excluding the operation of loading and unloading the working medium, support cradles and clamps installed on at least two pairs of hydraulic cylinders, which are rigidly fixed in the container, and the upper cavity of one of the hydraulic cylinders of each pair is connected to the source pressure, and the lower cavity of another hydraulic cylinder - with a tank filled with liquid, the level of which is located above the level of the hydraulic cylinders.
