Technical Field

[0001] The utility model relates to the technical field of magnetic tile processing, in particular to a magnetic tile production grinding device. Background Art

[0002] Magnetic tiles are a type of permanent magnet primarily used in permanent magnet motors. They spontaneously align themselves in the absence of an external magnetic field, forming small, self-magnetized regions known as magnetic tiles. During the tile production process, burrs or unevenness often appear on the outer or inner surfaces, affecting the tile's quality.

[0003] Chinese patent CN214237611U discloses a magnetic tile grinding device, which is equipped with a semicircular groove and a grinding block. The grinding block is rotated by a cylinder to grind the magnetic tile with burrs or uneven surface. The magnetic tile with burrs or uneven surface rubs against the groove, thereby achieving the effect of grinding some magnetic tiles with burrs or uneven surface.

[0004] However, this patent still has the following problems: during the grinding process of the magnetic tiles, the grinding block exerts force on the magnetic tiles, which causes the magnetic tiles to shift and shake, affecting the grinding accuracy. Utility Model Content

To this end, the present invention provides a magnetic tile production and grinding device that effectively prevents the displacement and shaking of the magnetic tile body during the grinding process, thereby improving the grinding accuracy, while also enabling rapid synchronous positioning and improving work efficiency.

[0006] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the present utility model, a magnetic tile production grinding device is proposed, including a grinding seat and a positioning mechanism, the grinding seat is provided with a positioning groove, and a magnetic tile body is arranged in the positioning groove; the positioning mechanism includes a first screw rod, a positioning plate and a connecting shaft, the side walls of the positioning groove are provided with sliding grooves, the sliding grooves on both sides are provided with a first screw rod, and a first bevel gear is provided at the bottom of the first screw rod, the connecting shaft is provided at the bottom of the positioning groove, and a second bevel gear is provided at both ends of the connecting shaft, and the second bevel gears at both ends are respectively meshed with the first bevel gears on both sides, one end of the positioning plate is provided with a mounting block, the mounting block is provided on the first screw rod, and the positioning plate positions the top of the magnetic tile body; one end of the connecting shaft passes through the grinding seat and is connected to a rotating ring, and the rotating ring controls the synchronous movement of the positioning plates on both sides.

A clamping groove is provided at the bottom of the positioning plate, and the adjusting block is provided at the top of the clamping plate. The adjusting block is slidably set in the clamping groove, and the spring is connected between the side wall of the adjusting block and the side wall of the clamping groove. The clamping plate clamps the inner ring of the magnetic tile body.

[0008] As a further solution of the present invention: a rounded corner is provided on one side of the clamping plate facing the inner circle of the magnetic tile body.

[0009] As a further solution of the present invention: an arc-shaped groove is provided at the bottom of the positioning groove, and the size of the outer ring of the magnetic tile body is adapted to the arc-shaped groove.

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, a magnetic tile production grinding device includes a grinding seat 1 and a positioning mechanism. A positioning groove 11 is provided on the grinding seat 1, and a magnetic tile body 2 is arranged in the positioning groove 11; an arc groove 13 is provided at the bottom of the positioning groove 11, and the outer ring size of the magnetic tile body 2 is adapted to the arc groove 13.

[0022] The positioning mechanism includes a first screw rod 3, a positioning plate 5 and a connecting shaft 4. The side walls of the positioning groove 11 are provided with sliding grooves 12. The first screw rods 3 are provided in the sliding grooves 12 on both sides, and a first bevel gear 31 is provided at the bottom of the first screw rod 3. The connecting shaft 4 is provided at the bottom of the positioning groove 11. Second bevel gears 41 are provided at both ends of the connecting shaft 4. The second bevel gears 41 at both ends are respectively engaged with the first bevel gears 31 on both sides. A mounting block 52 is provided at one end of the positioning plate 5. The mounting block 52 is provided on the first screw rod 3. The positioning plate 5 positions the top of the magnetic tile body 2; one end of the connecting shaft 4 passes through the grinding seat 1 and is connected to a swivel 42. The swivel 42 controls the synchronous movement of the positioning plates 5 on both sides.

[0023] By rotating the swivel 42, the connecting shaft 4 is driven to rotate. Since the second bevel gears 41 at both ends of the connecting shaft 4 mesh with the first bevel gears 31 on the first screw rods 3 on both sides, power is transmitted, which in turn drives the first screw rod 3 to rotate, so that the positioning plates 5 on both sides simultaneously approach the top of the magnetic tile body 2, forming a stable positioning. This effectively prevents the displacement and shaking of the magnetic tile body 2 during the grinding process, thereby improving the grinding accuracy, and can quickly achieve synchronous positioning and improve work efficiency. After positioning is completed, the inner ring surface or corners of the magnetic tile body 2 can be ground using tools such as grinding wheels and grinding wheels.

[0024] An inner ring clamping mechanism is provided on the positioning plate 5, and the inner ring clamping mechanism includes a clamping plate 6, an adjusting block 61 and a spring 63. A clamping groove 51 is provided at the bottom of the positioning plate 5, and the adjusting block 61 is provided on the top of the clamping plate 6. The adjusting block 61 is slidably set in the clamping groove 51, and the spring 63 is connected between the side wall of the adjusting block 61 and the side wall of the clamping groove 51. The clamping plate 6 clamps the inner ring of the magnetic tile body 2; the clamping plate 6 is provided with a rounded corner 62 on the side facing the inner ring of the magnetic tile body 2.

[0025] When the positioning plate 5 limits the top of the magnetic tile body 2, the top of the magnetic tile body 2 abuts against the clamping plate 6, and the clamping plate 6 shrinks toward the inner circle of the magnetic tile body 2 under the action of the adjusting block 61 and the spring 63. When the bottom of the positioning plate 5 is connected to the top of the magnetic tile body 2, the clamping plate 6 clamps the inner circle of the magnetic tile body 2 under the action of the rebound force of the spring 63, which effectively improves the installation stability of the magnetic tile body 2. At the same time, the spring 63 can buffer the vibration during the grinding process and improve the grinding accuracy. By setting the rounded corners 62 on the clamping plate 6, the direct contact area between the clamping plate 6 and the edge of the magnetic tile is reduced, the risk of scratches and damage is reduced, and the integrity and performance of the magnetic tile are protected.

[0026] A rotating handle 43 is provided on the rotating ring 42 .

[0027] By providing the rotating handle 43 , the operator can more easily and intuitively control the rotation of the rotating ring 42 , thereby improving the efficiency and accuracy of positioning.

[0028] The working principle of this utility model is as follows: During the grinding process of the magnetic tile body 2, the magnetic tile body 2 is placed in the positioning groove 11. The rotating handle 43 on the rotating ring 42 drives the connecting shaft 4 to rotate. The meshing of the second bevel gear 41 and the first bevel gear 31 transmits power, causing the first screws 3 on both sides to rotate synchronously, thereby driving the positioning plate 5 along the slide groove 12 to approach the top of the magnetic tile body 2, thus achieving positioning. At the same time, the clamping plate 6 at the bottom of the positioning plate 5, under the action of the spring 63 and the adjustment block 61, automatically clamps the inner ring of the magnetic tile, improving the installation stability of the magnetic tile body 2 and enhancing the accuracy and efficiency of subsequent grinding work.

[0029] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
