Stacking equipment for cast plunger pumps

Abstract

The invention belongs to the technical field of plunger pump manufacturing, and particularly relates to stacking equipment for cast plunger pumps. The stacking equipment comprises a base, wherein lifting mechanisms are installed on the lower surface of the base, a first sliding plate is arranged on the base in a sliding fit mode, a second sliding plate is in sliding fit with the first sliding plate, a limiting sleeve is vertically and fixedly installed on the upper surface of the second sliding plate, a supporting column is vertically in sliding fit with the interior of the second sliding plate, a buffer mechanism is mounted in the limiting sleeve, a horizontal top plate is fixedly mounted at the top of the supporting column; and a clamping mechanism is mounted on the top plate. Accordingto the stacking equipment, in the process of clamping the plunger pump through a clamping mechanism, a supporting rod can freely stretch out and draw back in a sealing barrel according to the shape ofthe surface of the plunger pump, so that the irregular surface of the plunger pump is supported, and stable clamping of the plunger pump is achieved; and the plunger pump can slowly descend through the buffer mechanism, so that the position of the plunger pump can be finely adjusted, and a plunger pump shell is fully matched with the inner wall of a storage box.

Description

technical field [0001] The invention belongs to the technical field of plunger pump manufacturing, and in particular relates to a stacking equipment for a plunger pump after casting. Background technique [0002] The plunger pump is an important device of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, so it is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, engineering machinery and ships. The plunger pump is usually molded by casting. After casting, in order to facilitate storage and transportation of the plunger pump, it is necessary to put the plunger pump into a storage box that cooperates with its shell. At present, the process of stacking the plunger pump is don...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a post-casting stacking equipment for plunger pumps. The purpose is to solve the following problems in the current manual stacking of plunger pumps: (1) The surface shape of the plunger pump is irregular, and the plunger pump cannot be stacked by hand. Stable clamping may easily cause the plunger pump to fall off, resulting in collision between the plunger pump and the inside of the storage box, resulting in damage to the plunger pump; (2) It is impossible to slowly put the plunger pump into the storage box during manual stacking At the same time, fine-tune its position, which will easily cause the mismatch between the plunger pump shell and the inner wall of the storage box, resulting in the formation of extrusion force between the two. Long-term extrusion will also cause damage to the plunger pump.
