Abstract

The invention discloses an improved integrated weight loading mechanism for cylindrical weights, which comprises a piston weight (31) connected to a lower piston rod (92) for weighing or pressure calibration; the upper part of the piston weight is connected through a connecting structure A pallet weight (34); a group of nested cylindrical weights (20) are arranged on the pallet weight; a vertical upward cylinder (99) is arranged symmetrically on the periphery of the piston weight and the cylindrical weight, and is equipped with A plurality of vertical guiding optical axes (4) are set; the optical axis and the upper cylinder are placed on the lower plate (9); the optical axis passes through the upper plate (8); the upper plate is fixed on the piston rod of the upper cylinder (89) top; the cylindrical weight is provided with a cylindrical weight loading and unloading unit connected to the upper plate (8). The invention improves the overall structural design of the loading mechanism, and the supporting and guiding structure has the characteristics of high stability, good guiding and convenient operation.

Description

technical field [0001] The present invention relates to an automatic weight adding device, more particularly, to the structural improvement of a piston pressure gauge. Background technique [0002] Pressure is one of the important process parameters in industrial production. In the field of pressure detection, it is often necessary to detect system pressure. Various forms of pressure gauges, pressure sensors, and pressure transmitters are commonly used instruments for pressure detection. , aerospace, automotive, power generation, medium transmission, water supply and gas supply and other almost all fluid-related fields. The performance of the pressure gauge is directly related to the quality of the test results. In order to ensure the test accuracy of the instrument, the pressure gauge must be regularly calibrated. If pressure detection is inaccurate, it will not only affect production efficiency, reduce product quality, but even cause serious safety accidents, so pressure ...

Problems solved by technology

[0003] Piston pressure gauge is a common instrument for pressure gauge detection and calibration. The weight is generally the benchmark for piston pressure gauge pressure gauge detection and calibration. A specific weight is formed through a specific combination of weights, which is converted into liquid pressure by the hydraulic system and applied to the pressure gauge. , is the usual practice of pressure gauge detection, but the current piston pressure gauge, weight loading and unloading work, weight status determination and other work are generally done manually, the operator repeats the work, the work is boring, the degree of automation is low, and it is easy to produce verification. error, and manual operation is easily affected by factors such as operator's emotion and experience, and it is easy to damage the weight and related parts

That is to say, the weight loading method of the piston pressure gauge is mainly manual loading at present, and the weight placement depends on manual handling, which is time-consuming, labor-intensive, poor in reliability and stability, and an automated weighting process and device are necessary
