Embodiment Construction

[0043] like Figure 1-7 The combined weight loading mechanism shown in 27-31 includes a piston weight 31 connected to the lower piston rod 92 for weighing or pressure calibration; the upper part of the piston weight 31 is hooked to the upper part of the cylindrical hanging basket weight 33 At the center of the cylinder mouth; the outer side of the bottom of the cylinder wall of the hanging basket weight 33 is connected to a radial annular weight tray 23 , and the weight tray 23 carries the annular disc-shaped weights 22 arranged in layers. The upper part of the piston weight 31 is also connected with a tray weight 34 located above the hanging basket weight 33 through a connection structure; a set of sleeved cylindrical weights 20 are set on the tray weight 34 . The disc-shaped weight 22 is provided with an independent disc-shaped weight loading and unloading unit. The cylindrical weight 20 is provided with an independent cylindrical weight loading and unloading unit.

Abstract

The invention discloses an improved loading mechanism for disk-shaped weights, which comprises several stacked disk-shaped weights with flanges on the edges, a weighing part and a loading and unloading part; the weighing part includes a weight tray; the loading and unloading part It includes at least three pull rods (16) of the same structure that are vertically arranged on the periphery of the disc-shaped weight; the pull rods are respectively connected to the vertical drive unit that moves up and down synchronously in the manner of rotating around their own axes; the pull rods Corresponding to the flange of each layer of disc weights in the axial direction, a radially outward overlapping convex plate (95) is arranged. The vertical drive unit includes an upper top cylinder (99), a vertical guide optical axis (4), and an intermediate plate (7) driven vertically by the upper top cylinder; each code puller passes through a bearing (13) on a The middle plate is relatively fixed vertically with the middle plate through the positioning component. The disk-shaped weight loading mechanism of the invention has the characteristics of flexible operation, compact structure and moderate cost.

Description

technical field [0001] The present invention relates to a weighing mechanism, and more particularly, to a disk-shaped weight loading mechanism. Background technique [0002] In the field of physical quantity detection, it is often necessary to detect system pressure. Pressure is one of the important process parameters in industrial production, and a pressure gauge is an instrument used to measure pressure. Various forms of pressure gauges, pressure sensors and pressure transmitters are commonly used instruments for pressure detection, and their applications are in almost all fluid-related fields such as chemical industry, petroleum, aerospace, automobile, power generation, medium transmission, water supply and gas supply. The performance of the pressure gauge is directly related to the quality of the test results. In order to ensure the detection accuracy of the pressure gauge, the pressure gauge must be regularly calibrated. If the pressure does not meet the requirements,...
