Synchronous clamping water passing device and working method thereof

Abstract

The invention relates to a synchronous clamping water passing device and a working method thereof, and belongs to the field of water pump testing tools. The synchronous clamping water passing device includes a rack, a guide rail, sleeves, flange sleeves, a left movable frame, a right movable frame, a telescopic cylinder, a fixed hinge shaft, a rotary rod, a first hinge shaft, a second hinge shaft,a third hinge shaft, a fourth hinge shaft, a first connecting rod and a second connecting rod; the guide rail is on the rack, the flange sleeves are arranged on the two sides of the rack, the left movable frame and the right movable frame are provided with the sleeves, and the sleeves and the flange sleeves are matched; and one end of the telescopic cylinder is located on the left movable frame,the other end of the telescopic cylinder is located on the right movable frame, the fixed hinge shaft is arranged on the rack, the rotary rod of the third hinge shaft and the fourth hinge shaft is matched with the fixed hinge shaft, one end of the first connecting rod and one end of the second connecting rod are matched with the fourth hinge shaft and the third hinge shaft correspondingly, and theother end of the first connecting shaft and the other end of the second connecting rod are matched with the first hinge shaft and the second hinge shaft. The synchronous clamping water passing deviceis simple and reasonable in structural design, safe, reliable, convenient to operate, good in repeated positioning accuracy, reasonable in production cost and convenient to popularize.

Description

technical field [0001] The invention relates to a device and a method, in particular to a synchronous clamping water passing device and a working method thereof, belonging to the field of water pump test equipment. Background technique [0002] There is a test station in the vertical pump production line. In order to allow the water pump flowing into the test station to perform automatic testing, the existing structure cannot solve the problem of high positioning accuracy of the water pump at the test station on the assembly line. Problems, inconvenient operation, poor repeat positioning accuracy, and high production cost. [0003] The publication date is March 2, 2018, and the Chinese patent with the publication number 107747548A discloses a utility model patent titled "a vertical axial suction centrifugal pump semi-submersible hydraulic testing device". The patent includes a test cylinder, a lifting platform, a water suction pipeline, an executive motor, an adjustment scr...
