[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] like Figures 1-4 As shown, this utility model provides a magnetic flipping platform for coating lost foam casting models, comprising the following structure:

[0025] 1. Base and moving structure

[0026] The base 1 is a rectangular frame structure, including a horizontal frame 11 and a vertical frame 12, welded from high-strength steel plates. Four sets of rollers 4 are installed at the four corners of the bottom, two sets being omnidirectional wheels with brakes, and the other two being directional wheels, facilitating flexible platform movement and positioning. The rollers 4 are bolted to the bottom of the base 1 to ensure stable load-bearing capacity of the platform.

[0027] 2. Tilting mechanism

[0028] The tilting mechanism 2 is fixed above the center of the base 1 and includes a tilting shaft 21 and a drive unit 22. The drive unit 22 is a servo motor, which is fixed to one side of the base 1 by bolts, and its output shaft is connected to the tilting shaft 21 via a coupling. The two ends of the tilting shaft 21 are connected to the side walls of the base 1 by deep groove ball bearings to ensure smooth rotation. A planetary gear reducer 23 is connected in series on one side of the drive unit 22 with a reduction ratio of 1:50 to provide high torque output and achieve precise low-speed rotation of the tilting shaft 21.

[0029] 3. Magnetic attraction mechanism

[0030] The magnetic attraction mechanism 3 is fixed at both ends of the flip shaft 21, specifically including: base frame 31: a U-shaped steel frame, one end of which is welded and fixed to the flip shaft 21, and two parallel rail grooves 35 are opened on the upper surface of the base frame 31, with wear-resistant nylon pads embedded in the grooves.

[0031] Movable frame 32: Two sets of movable frames 32 are symmetrically arranged on both sides of the base frame 31. A boss 34 is welded to the bottom of each frame, and the boss 34 is embedded in the rail groove 35 to achieve a sliding fit. The movable frame 32 can be adjusted laterally along the rail groove 35 by manual or pneumatic push rods to adapt to the clamping requirements of workpieces of different sizes.

[0032] Magnetic component 36: An electromagnetic magnetic block (adsorption force adjustable from 50 to 500N) is installed at the front end of each set of movable frames 32. After being powered on, it is attracted and fixed to the end face of the base frame 31, locking the position of the movable frame 32.

[0033] Clamping arms 33: Two pairs of clamping arms 33 are vertically arranged on the movable frame 32. V-shaped platforms 40 are welded to the ends of the clamping arms 33, which slide and engage with the V-shaped grooves 39 on the movable frame 32 to achieve longitudinal position adjustment of the clamping arms 33. Clamping plates 38 are welded to both ends of the clamping arms 33. Polyurethane shock-absorbing pads are bonded to the contact surfaces of the clamping plates 38 to prevent damage to the workpiece surface.

[0034] Magnetic limiting component 37: An electromagnetic magnetic block is installed in the middle of the clamping arm 33. After being energized, it is attracted and fixed to the side of the moving frame 32 to ensure that the clamping arm 33 firmly clamps the workpiece.

[0035] 4. Support components

[0036] Adjustable support components 5 are installed at the four corners of the base 1, including: screws 52: which engage with threaded holes at the bottom of the base 1 and can be rotated to adjust the height.

[0037] Support plate 51: It is a circular cast iron plate that is rotatably connected to the lower end of screw 52 via a thrust bearing to increase the contact area with the ground.

[0038] Turntable 53: Welded to the top of screw 52, ​​with anti-slip texture on the surface, it is easy to manually rotate and adjust the support height to ensure stable support of the platform when it is stationary.

[0039] Operating procedures

[0040] Workpiece clamping: The moving frame 32 is adjusted along the rail groove 35 to a position that matches the width of the workpiece, and the magnetic suction component 36 is energized and locked; the clamping arm 33 is adjusted in height through the V-groove 39, and the magnetic suction limiting component 37 is energized and fixed; the workpiece is placed between the clamping plates 38 and flexibly clamped by the polyurethane shock-absorbing pad.

[0041] Coating application: The drive unit 22 is started, and after the speed is reduced by the reducer 23, it drives the flipping shaft 21 to rotate slowly, so that the workpiece is tilted at multiple angles, which facilitates the uniform application of coating.

[0042] Movement and Fixation: The roller 4 moves the platform to the designated work position, and the screw 52 of the support component 5 is adjusted to lift the roller 4 off the ground, thus providing stable support for the platform.

[0043] Example 2

[0044] This embodiment is basically the same in structure as Embodiment 1, except that:

[0045] The magnetic attraction component 36 and the magnetic attraction limiting component 37 adopt a composite structure of permanent magnet and electromagnetic. When the power is off, the basic attraction force (50N) is maintained, and when the power is on, it can be increased to 500N, thereby improving safety.

[0046] The drive unit 22 is replaced with an explosion-proof motor, which is suitable for foundry workshops in flammable environments.

[0047] The above embodiments significantly improve the coating efficiency and uniformity of lost foam casting models through magnetic quick clamping, multi-directional adjustment, and low-speed flipping functions, and have high industrial application value.

[0048] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
