Embodiment 2

[0064] like Figure 10 As shown, the process of utilizing the device in Embodiment 1 to carry out dynamic load automatic loading is as follows:

[0065] S1, the clamping of the barrel. The calculation unit sends a signal to the driving device to control the driving motor of the V-shaped clamping and fixing mechanism of the draft beer keg to realize the clamping of the keg. At the same time, the spoke-type force sensor at the bottom of the V-shaped clamping and fixing mechanism transmits the detected pressure value to the computing unit in real time through the multi-function data acquisition card. When the clamping force reaches the set pressure threshold, the clamping stops and continues.

[0066] S2. Determine the loading position of the dynamic load. According to the actual measurement requirements, adjust the installation position of the dynamic load loading guide rod on the radial loading beam.

[0067] S3. Adsorption of weights. The calculation unit controls the late...

Abstract

The invention provides an automatic testing method and system for radial mechanical properties of a cork base of a draught-beer barrel. According to the invention, a crossbeam is arranged at the port of the cork base and used as a conducting material for applied load; in testing, standard dynamic or static load force vertically acts on an assigned position of the crossbeam, and prescribed bending moment test load is accurately applied on the cork base so as to allow the cork base to undergo radial deviation; and the value of deflection of the far end of the crossbeam is acquired and used for measurement of radial deviation of the cork base. The automatic testing method and system provided by the invention can realize accurate positioning and clamping of a to-be-tested draught-beer barrel, automatic continuous loading of load and accurate measurement and storage of testing data, so disadvantages of conventional manual operation in testing of the radial mechanical properties of cork bases in factories are overcome, and testing efficiency and precision are improved.

Description

technical field [0001] The invention relates to a technology in the field of daily necessities manufacturing, in particular to a method and system for automatically testing the radial mechanical properties of a draft beer barrel spear seat. Background technique [0002] As the proportion of draft beer in the world's beer consumption is getting higher and higher, the application of draft beer kegs is also increasing. The draft beer barrel is a closed stainless steel container, generally cylindrical, with a thin-walled dome structure on the top of the barrel, and the wine spear seat is welded in the center of the dome, which plays the role of sealing and fixing the wine spear. Due to the limitation of the space structure, there are usually no special strengthening measures between the wine spear seat and the barrel roof. In addition, the dome is thin. When subjected to radial force and impact load, the wine spear seat and the dome are prone to joint deformation together. Caus...
