Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, a novel floating electric permanent magnet fixture comprises a pushing cylinder 10, a fixed limiting plate 20, a guiding and positioning plate 30, a floating connecting plate 40, and an electromagnetic absorbing part 50 for absorbing a workpiece, wherein the electromagnetic absorbing part 50 is fixedly installed at the floating connecting plate 40, the pushing cylinder 10 is fixedly installed at the fixed limiting plate 20, the floating connecting plate 40 is arranged at the fixed limiting plate 20 in a floating manner along the Z-axis direction, the guiding and positioning plate 30 is arranged between the fixed limiting plate 20 and the floating connecting plate 40, the upper end surface of the guiding and positioning plate 30 is abutted to an expansion link 11 of the pushing cylinder 10, a floating spring 60 is arranged between the lower end surface of the guiding and positioning plate 30 and the floating connecting plate 40, a positioning pin 31 is arranged at the guiding and positioning plate 30, and a positioning pin seat 41 matched with the positioning pin 31 is arranged at. As shown in fig. 1, the positioning pin member 31 is locked to the guide positioning plate 30 by a screw, and the positioning pin boss 41 is locked to the floating connection plate 40 by a screw.

Referring to fig. 1, one end of the floating spring 60 abuts against the guide positioning plate 30, and the other end of the floating spring 60 abuts against the floating connection plate 40. The end of the telescopic rod 11 of the pushing cylinder 10 is fixedly provided with a pushing piece 12, and the pushing piece 12 is abutted against the guide positioning plate 30.

When in use, as shown in fig. 1 and fig. 3, the telescopic rod 11 of the pushing cylinder 10 pushes the guiding positioning plate 30 to move downwards, the guiding positioning plate 30 pushes the floating spring 60 downwards at the same time in the process of moving downwards, the floating spring 60 pushes the floating connecting plate 40, the floating connecting plate 40 and the electromagnetic absorbing piece 50 fixedly installed at the floating connecting plate 40 move downwards at the same time, when the electromagnetic absorbing piece 50 descends to contact with a workpiece, the floating connecting plate 40 reaches its limit position, at this time, the guiding positioning plate 30 still moves downwards under the pushing of the telescopic rod 11 of the pushing cylinder 10, along with the continuous downward movement of the guiding positioning plate 30, the floating spring 60 arranged between the guiding positioning plate 30 and the floating connecting plate 40 is pressed continuously to generate elastic deformation, when the positioning pin piece 31 at the guiding positioning plate 30 is inserted into the positioning pin seat 41 at the floating connecting plate 40, the guide positioning plate 30 moves down to its extreme position.
