Hydraulic pump and assembly machine thereof

Abstract

The invention relates to the field of hydraulic pumps. An assembly machine of a hydraulic pump comprises a rack, a rotary jig device, a pump cover feeding device, a screw locking device and a sealingdetection device, wherein the rotary jig device, the pump cover feeding device, the screw locking device and the sealing detection device are arranged on the rack, the rotary jig device is arranged atthe center of the rack, the pump cover feeding device, the screw locking device and the sealing detection device respectively correspond to one station of the rotary jig device, four stations are arranged on the jig device, and a loading and unloading conveying device is arranged at the remaining station. The assembly machine of the hydraulic pump has the advantages of high hydraulic pump assembly precision and high jig circulation efficiency, high pump cover assembly precision, accurate separation and transportation of pump covers and accurate sealing detection.

Description

technical field [0001] The invention relates to the field of hydraulic pumps, in particular to a hydraulic pump and an assembly machine and method thereof. Background technique [0002] Hydraulic pump installations are generally portable and are therefore equipped with a self-sufficient energy source such as a battery or the like. On the one hand, the hydraulic pump device is used as a component of a hydraulically driven rescue tool, such as a so-called spreader or cutting tool, which is used by a task force to rescue people trapped in vehicle wrecks or buried staff. On the other hand, said hydraulic pump devices are also used in tool technology, for example for shredding waste parts and the like. A switching valve, which is usually used for operating hydraulically driven tools, is located adjacent to the tool, so that the operator can control the tool directly via the switching valve as desired. The airtightness requirements of the hydraulic pump are relatively high. Aft...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the rigid impact of the hydraulic pump assembly process in the prior art is large, which affects the sealing performance, and the position of the hydraulic pump in the jig is easy to move, which affects the assembly accuracy; The process constantly adjusts the pipetting height every time, which leads to low efficiency and unreliable structure; the assembly accuracy of the pump cover is low; the detection is not accurate when the foaming agent is used to detect the seal, and it is not suitable to observe when the foaming agent is applied unevenly. A hydraulic pump assembly machine with high assembly precision, efficient jig circulation, high pump cover assembly accuracy, accurate pump cover separation and handling, accurate seal detection, and a working method thereof
