Description

Technical Field

[0001] This utility model relates to a magnetic steel assembly and testing device. Background Technology

[0002] After production, magnets need to be installed onto workpieces, such as injection-molded parts. The injection-molded part has an upward-facing groove at its top, and the magnet needs to be placed into this groove. Currently, when assembling magnets, the injection-molded part is first placed on a fixture and fixed in place. Then, the magnet is manually placed into the groove of the injection-molded part, and a pressing device is used to press the magnet down to tighten it. After pressing, the injection-molded part is removed. After assembly, the product needs to be tested to ensure the magnet is properly released from the pressure. Then, the product is manually placed on a magnetic flux testing device for testing. After testing, it can be removed and collected. The entire process usually involves manual assembly combined with multiple semi-automatic machines, resulting in low assembly efficiency and low work efficiency. Utility Model Content

The pressing platform 51 is fixed to the left end of the first lifting platform 54. The lower end of the pressing platform 51 has a groove 511 with an opening facing downwards. One end of the workpiece 4 has a mounting platform 41. The mounting platform 41 has a slot 411 with an opening facing upwards for inserting a magnet. The groove 511 at the lower end of the pressing platform 51 allows the mounting platform 41 to extend into it. The pressing platform 51 has a through hole 512 extending vertically. The lower end of the through hole 512 communicates with the groove 511. A second lifting platform 57 is fixed to the piston rod end of the lower end of the second lifting cylinder 56. A pressing strip 58 extending vertically is fixed to the outside of the second lifting platform 57. The pressing strip 58 extends into the through hole 512. The first lifting cylinder 53 is used to drive the first lifting platform 54 to move up and down, thereby driving the pressing platform 51 to move up and down.
