Description

Technical Field

[0001] The utility model relates to the technical field of impact energy calibration of spring impactors, and particularly relates to a full-automatic special energy generating device. Background Art

[0002] The spring impactor impact energy calibration device is mainly used for the test device of spring impactor impact energy calibration. The special energy generator is a device that generates an energy value according to the mass and drop height of the impact element, and is also a device used to calibrate the "spring impactor impact energy calibration device".

[0003] At present, the method adopted by the calibration device is according to the requirements in JF (SU) 205-2018 "Calibration Specification for Spring Impactor Impact Energy Calibration Device". The principle of the special energy generator is as follows:

[0004] As Figure 1 shown, the impact element "g" removed from the spring impactor to be calibrated, before calibration, the release mechanism of the calibration device is removed from the calibration device.

[0005] As Figure 2 shown, the impact element is hung at four suspension points on the horizontal plane 2000 mm above its final stop position by four wire ropes "h".

[0006] Calibrate the contact point "k" where the impact element swings and impacts the pendulum. The dynamic contact point should not move down more than 1 mm relative to the static position, and it can be adjusted by raising the position of the suspension point. The raised distance is equal to the distance between the dynamic and static contact points. After adjusting the suspension system, the axis of the impact element "g" should remain horizontal and perpendicular to the impact surface of the pendulum "c" during impact.

[0007] When the impact element is in the static position, the calibration device should be set so that the head of the impact element just touches the contact point "k". In order to obtain reliable results, the calibration device should not be moved or relocated casually after being fixed. The impact element can be positioned by a thin wire "m", and the impact element can be released when the thin wire is cut.

[0043] Among them, the reference Figure 5 As shown in Figure 5 , it further includes a wire rope automatic adjustment device 10.

The wire rope automatic adjustment device 10 includes a pulley block 102, a servo motor 103, a tension sensor 104, and a wire rope collecting cylinder 101;
