Description

Technical Field

[0001] The utility model relates to the technical field of vibration test equipment, in particular to a split magnetic cylinder structure used for a vibration test bench. Background Art

[0002] It is used to simulate the environment of electrical, electronic, automotive parts and other products and goods involved in transportation during transportation, and test the vibration resistance of the products. It realizes all the functions required for vibration test: sine wave, frequency modulation, sweep frequency, programmable, frequency doubling, logarithm, maximum acceleration, amplitude modulation, and time control.

[0003] However, when disassembling and assembling the electric vibration table, it is usually necessary to first separate the upper pole plate and the movable system from the magnetic cylinder, and then flip the magnetic cylinder body to release the screw connection between the lower pole plate and the magnetic cylinder body, so as to remove the lower pole plate. However, since the magnetic cylinder, especially the magnetic cylinder of a larger power vibration table, is very heavy, it is impossible to disassemble the entire magnetic cylinder as a whole, so it is necessary to use equipment such as a crane, and the operation is extremely complicated. In addition, if you are not careful during the operation, it is easy to cause damage to the magnetic cylinder or the equipment attached to the magnetic cylinder, which is prone to accidents.

[0004] In order to solve the above problems, patent CN215640012U discloses a split magnetic cylinder body for a vibration test device, which relates to the technical field of vibration test equipment. The magnetic cylinder body is composed of four identical four-magnetic cylinder body assemblies that are mutually clamped through a first clamping groove, a second clamping groove, a first clamping block, and a second clamping block to form a component. It is easy to disassemble and assemble, and there is no need to use large-scale lifting equipment, which greatly reduces the production cost and improves work efficiency. The magnetic cylinder body is composed of multiple identical magnetic cylinder body assemblies. When one of the magnetic cylinder body assemblies is damaged, it can be disassembled and replaced with a new magnetic cylinder body assembly. Moreover, the magnetic cylinder body assemblies of each part are exactly the same, thereby improving the versatility of parts.

[0005] However, this structure has the following defects and shortcomings: the structure is single, the support stability is not high, and the installation is not firm enough. Therefore, we propose a split magnetic cylinder structure for a vibration test bench to solve the above problems. Utility Model Content

[0008] The sandwich plate layer and the magnetic cylinder body are limitedly connected by a limit clamping assembly;

[0009] The outer frame and the plywood layer are fixedly connected by bolts via a third bolt connection assembly;

[0010] The magnetic cylinder body is composed of a plurality of magnetic cylinder body components which are distributed at equal angles and circumferences, and adjacent magnetic cylinder body components are fixedly connected by bolts via a second bolt connection assembly.

[0011] Preferably, the first bolt connection assembly includes first mounting holes circumferentially distributed at equal angles on the magnetic cylinder body and second mounting holes circumferentially distributed at equal angles on the base, and the first mounting holes are fixedly connected to the second mounting holes by bolts.

[0012] Preferably, the limit clamping assembly includes limit grooves equiangularly distributed on the magnetic cylinder body and limit columns equiangularly distributed and fixed on the plywood layer, the bottom surface of the limit column is smooth and in contact with the base surface, and the top is movably clamped in the limit groove.

[0015] Preferably, the bottom surface of the outer frame is smooth and in contact with the upper surface of the magnetic cylinder body, and is used to press and limit the upper surface of the magnetic cylinder body.
