[0037] The device includes:

[0038] A workbench 11 and a support 12;

[0039] The chip cutting assembly includes a plurality of groups of concentric circular tracks with different diameters, each group of circular tracks is relatively arranged on the workbench 11 and the bracket 12, and the positions are corresponding, wherein a slider 24 is arranged in any group of circular tracks, the slider 24 is slidably matched with the circular track, and the relative sliders 24 are connected by a connecting rod 25, and a grinding cutter 26 is rotatably arranged on the connecting rod 25;

[0040] The chip assembly also includes a mounting block 28, which is rotatably mounted on the bracket 12. A telescopic rod 27 is hingedly mounted on one side of the mounting block 28. The other end of the telescopic rod 27 is hingedly mounted on the slider 24 on the side. An embedding groove 241 is disposed on the slider 24 at one end close to the connecting rod 25. A spring 29 is disposed in the embedding groove 241. The slider 24 can slide at the end of the connecting rod 25. The slider 24 has at least a first state and a second state.

[0041] First state: the spring 29 is in a natural state, the slider 24 is movably embedded in the same set of annular tracks, and the mounting block 28 rotates to drive the telescopic rod 27 to drive the slider 24 to slide along the annular track;

[0042] The second state: applying external force to the slider 24 to compress the spring 29, so that the sliders 24 in the same set of annular tracks can all be separated from the annular tracks;

[0043] It also includes a fixed component, which is correspondingly arranged at the center position of the annular track group. The magnetic tile mold is installed on the fixed component. When the milling cutter 26 moves along the annular track, it cuts the four corners of the main body plate 1.

[0044] Specifically, the bracket 12 and the workbench 11 are arranged opposite to each other at the upper and lower parts, and two annular tracks of the same diameter arranged opposite to each other on the bracket 12 and the workbench 11 form a group, and the milling cutter 26 moves in any one group of annular tracks through the connecting rod 25 and the slider 24 to cut the four corners of the main plate 1 of the magnetic tile mold located in the middle, so that the four corners are rounded;

[0045] The fixed component is capable of positioning and fixing magnetic tile molds of different sizes. By setting a plurality of groups of concentric but unequal diameter annular tracks on the outside of the fixed component, and by setting a spring 29, a groove 241, and a telescopic rod 27, the position of the slider 24 can be adjusted, thereby switching the grinding cutter 26 to different annular track groups to achieve chamfering operations on magnetic tile molds of different sizes.

[0046] Specifically, the annular track group includes annular track 1 21, annular track 22 and annular track 3 23, wherein the diameters of the annular track 1 21, the annular track 22 and the annular track 3 23 increase in sequence;

[0047] When switching the annular track group, the two sliders are squeezed toward one end that is close to each other, the spring 29 is compressed, the slider 24 can be separated from the original track group, and then the slider 24 is transferred and embedded in another annular track group, the telescopic rod 27 will be adaptively extended and retracted, and after the slider 24 is transferred and embedded in another annular track group, the external force is removed, the spring 29 is reset, thereby resisting the slider 24, so that the slider 24 is stably embedded in the replaced annular track group, and finally the rotation of the mounting block 28 can drive the telescopic rod 27 to drive the slider 24 to slide along the annular track.

[0048] The spring 29 is selected according to the actual application environment. For example, the upper spring 29 should be able to overcome the gravity of the slider 24 at that end, resist the slider 24 and enable the slider 24 to be stably and movably embedded in the annular track.

[0049] Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, Figure 3 The figure shows the overall structure of the chamfering device in the embodiment. Figure 6 What is shown is a schematic front view of a fixing assembly in an embodiment; Figure 7 What is shown is a top view schematic diagram of the fixing assembly in the embodiment; Figure 8 What is shown is a schematic diagram of the matching relationship between the guide column and the clamping seat in the embodiment;

[0050] The fixing assembly includes a fixing seat 30 and a clamping seat 32 movably arranged on both sides of the fixing seat 30. The fixing seat 30 and the clamping seat 32 form a receiving groove for placing the raised portion 2 of the magnetic tile mold. The main body plate 1 of the magnetic tile mold is placed on the top of the clamping seat 32, and the clamping seats 32 are close to each other to clamp the raised portion 2.

[0051] The structure of the fixing component is adapted to the structure of the magnetic tile mold. When the magnetic tile mold is installed, its raised portion 2 is placed downward, the main body plate 1 is located above, and clamping seats 32 extend from the four sides of the main body plate 1. The clamping seat 32 can clamp the outermost raised portion 2 of the magnetic tile mold. The adjustable clamping seat 32 is suitable for magnetic tile molds of different sizes.

[0052] Electric push rods 33 are provided at the ends of the fixing seat 30 close to the clamping seats 32 on both sides. The output ends of the electric push rods 33 are connected to the clamping seats 32 on the side. The electric push rods 33 drive the clamping seats 32 to synchronously approach the fixing seat 30 or synchronously move away from the fixing seat 30.

[0053] The electric push rod 33 drives the clamping seats 32 on both sides to move closer to or away from each other, so as to realize the clamping action and the installation release action.

[0054] A plurality of guide posts 34 are arranged at intervals on the ends of the fixing seat 30 close to the clamping seats 32 on both sides. The clamping seats 32 are provided with guide grooves 321 for the guide posts 34 to be movably inserted into. The guide posts 34 are slidably matched with the guide grooves 321 .

[0055] The guide column 34 and the guide groove 321 are provided to increase the stability of the clamping seat 32 during the adjustment process, and within the adjustment range of the electric push rod 33 , the clamping seat 32 will not separate from the fixing seat 30 .

[0056] like Figure 3 As shown, Figure 3 What is shown is a schematic diagram of the overall structure of the chamfering device in the embodiment;

[0057] A motor 41 is disposed on the top of the bracket 12 , and an output end of the motor 41 passes through the bracket 12 and is connected to the mounting block 28 , and the motor 41 drives the mounting block 28 to rotate.

[0058] The motor 41 drives the mounting block 28 to rotate.

[0059] A fixed frame 42 is provided on the connecting rod 25, and the milling cutter 26 is rotatably provided on the fixed frame 42. A second motor 43 is also provided on the fixed frame 42. The output end of the second motor 43 is connected to the milling cutter 26, and the second motor 43 drives the milling cutter 26 to rotate.

[0060] The fixing frame 42 realizes the installation of the grinding cutter 26, and the motor 2 43 drives the grinding cutter 26 to rotate. The grinding cutter 26 can be selected as needed according to specific requirements.

[0061] Working principle: This device can fix and chamfer magnetic tile molds of different specifications. By switching the annular track groups of different diameters, the position and moving path of the grinding milling cutter 26 can be changed: when switching the annular track groups, the two sliders are squeezed toward one end close to each other, the spring 29 is compressed, and the slider 24 can be separated from the original track group, and then the slider 24 is transferred and embedded in another annular track group. The telescopic rod 27 will be adaptively extended and retracted, and after the slider 24 is transferred and embedded in another annular track group, the external force is removed, and the spring 29 is reset, thereby resisting the slider 24, so that the slider 24 is stably embedded in the replaced annular track group. Finally, the rotation of the mounting block 28 can drive the telescopic rod 27 to drive the slider 24 to slide along the annular track to achieve chamfering of the four corners of the magnetic tile mold.
