Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing equipment, and more specifically to a floating suction and fastening device for a 3D printing equipment mobile cart. Background Technique

[0002] Currently, a single mobile cart can only correspond to a single equipment rack. The magnetic steel plate on the mobile cart is docked with the electromagnet on the rack. When multiple mobile carts correspond to a single equipment rack, due to the machining and assembly errors of the magnetic steel plates on the mobile carts, there will be errors in the angle of the magnetic steel plates and the distance from the electromagnets, resulting in some mismatching problems, gaps between the electromagnets and the magnetic steel plates, and insecure suction.

[0003] Therefore, providing a floating suction and fastening device for a 3D printing equipment mobile cart with firm suction is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0004] In view of this, the utility model provides a floating suction and fastening device for a 3D printing equipment mobile cart, so that any mobile cart can be firmly sucked when corresponding to a single equipment rack.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A floating suction and fastening device for a 3D printing equipment mobile cart, including a fixed rack and a mobile cart. The fixed rack has a space for accommodating the mobile cart, and further includes an electromagnet, a plurality of spring plungers and a magnetic steel plate. The middle part of the electromagnet is installed on the back plate of the fixed rack through a shaft and a radial bearing; a plurality of the spring plungers are all located between the back plate and the electromagnet and are evenly distributed. The outer cylinder of each spring plunger is fixed on the back plate, and the plunger head of each spring plunger abuts against the electromagnet; the magnetic steel plate is fixed on the mobile cart and corresponds to the position of the electromagnet.

[0007] By adopting the above technical scheme, the beneficial effect of the utility model is:

[0008] When the mobile cart is pushed into the fixed rack and the magnetic steel plate contacts the electromagnet, under the action of the thrust, the plunger head in the spring plunger retracts, so that the magnetic steel plate and the electromagnet are closely attached, which is suitable for the docking of any mobile cart corresponding to a single equipment rack.

[0009] Furthermore, it further includes a step pin and a stop plate. The step pin is fixed on the back plate; the stop plate is fixed on the mobile cart and corresponds to the position of the step pin. Description of the Drawings

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0015] As Figures 1-3 shown, the embodiments of the present invention disclose a floating suction and tightening device for a 3D printing equipment mobile cart, which includes a fixed frame 1, a mobile cart 2, an electromagnet 3, a plurality of spring plungers 4, and a magnetic attraction steel plate 5. The fixed frame 1 has a space for accommodating the mobile cart. The middle part of the electromagnet 3 is installed on the back plate of the fixed frame 1 through a shaft and a radial bearing 6. The electromagnet 3 is slidably connected to the shaft and can move axially along it. In this embodiment, the number of electromagnets 3 is two and they are symmetrically distributed. A plurality of spring plungers 4 are all located between the back plate and the electromagnet 3 and are evenly distributed. The outer cylinder of each spring plunger 4 is fixed on the back plate, and the plunger head of each spring plunger 4 abuts against the electromagnet 3. In this embodiment, 4 spring plungers 4 are arranged between each electromagnet 3 and the back plate. The magnetic attraction steel plate 5 is fixed on the mobile cart 2 and corresponds to the position of the electromagnet 3. When the mobile cart 2 is pushed into the fixed frame 1 and the magnetic attraction steel plate 5 contacts the electromagnet 3, under the action of the thrust, the plunger head in the spring plunger 4 retracts, so that the magnetic attraction steel plate 5 and the electromagnet 3 are closely attached, which is applicable to the docking of any mobile cart 2 with a single equipment frame.
