Embodiment Construction
[0028] Such as Figure 1~3 as well as Figure 8 As shown, the gantry type lifting hanger mechanism includes: door frame 3, square flange fixing plate 4, electric push rod 5, guide optical axis 6, flange type linear bearing 7, pull rod type displacement sensor 8, wherein: The extension shaft of the electric push rod 5 is hinged with the loading head fixing seat of the electromagnetic weight loading mechanism through the push rod hanger 9, and the control driver drives the electric push rod 5 to drive the electromagnetic weight loading mechanism to realize vertical movement, wherein the guide light The shaft 6 plays a guiding role during the movement of the electromagnetic weight mechanism, so that the movement of the electromagnetic weight loading mechanism in the vertical direction is more stable.
[0029] One end of the rod displacement sensor 8 is fixed to the door frame 3, and one end passes through the round hole 10 reserved on the square flange fixing plate 4, and is fix...

A radial force loading device for testing a wine spear base comprises a portal type lifting hanging frame, an electromagnetic weight loading mechanism and a control driver. The whole portal type lifting hanging frame is fixed to a square flange fixing plate. The electromagnetic weight loading mechanism is hinged to the lower end of an electric push rod of the portal type lifting hanging frame. The wine spear base to be tested is located at the lower end of the electromagnetic weight loading mechanism. A weight is attached to the electromagnetic weight loading mechanism so that the loading position can be automatically adjusted and automatic loading can be achieved. The radial force automatic loading for testing the radial mechanical performance of the wine spear base is achieved, the defects of manual operation are overcome, and the precision and efficiency of testing work are improved.
Description
technical field [0001] The invention relates to a technology in the field of daily necessities manufacturing, in particular to a radial force loading device for wine spear seat testing. Background technique [0002] The wine spear is the wine outlet valve used on the beer barrel, which is combined with the wine spear seat on the barrel through threads to achieve the purpose of filling and wine delivery. Draft beer barrels are generally cylindrical, and the top of the barrel is a thin-walled dome structure. The wine spear seat is welded in the center of the dome to seal and fix the wine spear. During the production process, it is necessary to carry out a radial force loading test on the welded wine spear seat according to certain test standards to confirm that its mechanical properties meet the requirements. However, the top of the beer keg has a circular handle surrounding the spear seat, so it is difficult to directly apply radial static or dynamic impact loads to it. At ...
