[0020] The cross section of the eccentric wheel 6 is a pentagonal shape, that is, the distance from each face to the rotation center of the eccentric wheel 6 is different, and a circular arc chamfer is arranged between adjacent faces.

[0021] One side of the eccentric wheel 6 is rotationally fixed on the vertical column 1, and a column body 61 with a hexagonal cross section extends on the other side opposite to the one side, as shown in the accompanying drawings. Figure 4 、 3 A magnetic adsorption switch (not shown in the drawings) fixed on the transition plate 20 is closed, the column body 61 is screwed by a wrench, the eccentric wheel 6 integrated with the column body 61 is driven, the magnetic adsorption switch is opened again, and the lower surface of the fixed plate 41 is attached to the upward face of the eccentric wheel 6, that is, by screwing the eccentric wheel 6, the distance between the fixed plate 41 and the transition plate 20 can be adjusted, that is, the chamfer size of the lower chamfering mechanism can be adjusted, and the five-face eccentric wheel means that the eccentric wheel 6 can adjust the chamfer size of six gears, which is enough for ordinary chamfering plates.

[0022] The upper chamfering mechanism 3, the lower chamfering mechanism 4 and the longitudinal chamfering mechanism 5 all comprise a driving motor 42 and a cutter head 43, the cutter head 43 is fixed on the rotating shaft of the driving motor 42, and the driving motor 42 drives the cutter head 43 to rotate.

[0023] The workbench 1, column 1 21, and column 2 22 are all equipped with space slots 10. The surface of the workbench 1 with the space slot 10 is recessed 12 near the bottom end. This facilitates the placement of the operator's feet, allowing the body to fit snugly against the workbench, conforming to ergonomics. The space slot 10 is used to place miscellaneous items or tools.

[0024] The detection device 9 includes a strip groove 91 disposed on the side wall of the workbench 1, and an L-shaped measuring scale 92 slidably disposed relative to the strip groove 91. A parallel crossbar 93 is embedded within the strip groove 91. One end of the L-shaped measuring scale 92 has a through hole through which the crossbar 93 passes. The crossbar 93 has a directional cross-section, and the corresponding through hole is also a square hole. (See attached image) Figure 1 As shown, the workpiece to be chamfered (not shown in the figure) is generally square or rectangular and placed on workbench 1. Two adjacent faces rest against stop bars 7 and 8 respectively. Then, the upper chamfering mechanism 3 moves downwards towards the upper edge of workpiece 1, and the lead screw 210 rotates, causing column 21 to move laterally. This means the upper and lower chamfering mechanisms move laterally together to chamfer the upper and lower edges of the workpiece near stop bar 7. During the lateral movement of column 21, column 22 is pneumatically pushed towards the workpiece. Then, the lead screw 50 rotates, causing the vertical chamfering mechanism 5 to move downwards to chamfer the edge of the workpiece located between the two stop bars. After chamfering is complete, the upper chamfering mechanism 3 moves upwards, and column 21 returns to its original position. Simultaneously, the vertical chamfering mechanism 5 moves upwards, and column 22 returns to its original position. Then, the workpiece is flipped over or its other side is changed to perform chamfering on the other three sides.

[0025] Workpiece positioning is crucial in chamfering operations, as shown in the attached diagram. Figure 1 As shown, the workpiece is positioned by two guide bars. One end of guide bar 7 is fixed to the worktable 1, and the other end is fixed to the base 2. The end fixed to the base 2 is easily impacted when the workpiece is placed. Typically, the operator pushes the workpiece over, causing it to bump against the two guide bars to confirm its position accuracy. Therefore, the end of guide bar 7 near guide bar 8 is easily moved away from the worktable 1, meaning guide bar 7 is offset and no longer parallel to the worktable 1. While this slight offset is difficult to detect visually, it seriously affects the chamfering quality. Therefore, a detection device 9 is installed to measure the parallelism of guide bar 7. If a problem is found, it can be corrected promptly. This correction method can be to replace the L-shaped support rod 72, as shown in the attached diagram. Figure 6 As shown, the detection method is to push the L-shaped measuring ruler 92 along the horizontal bar 93 and observe whether there is an obvious gap between the L-shaped measuring ruler 92 and the stop bar 7. After the detection is completed, the L-shaped measuring ruler 92 is pushed to one end close to the fixed bar 71, which does not affect the normal operation of the CNC chamfering machine.

[0026] The present application effectively improves the problem that only single chamfering can be realized when chamfering the plate, the efficiency is low, and the labor cost is high, the structure of the numerical control chamfering machine is reasonable and simple, three edges can be chamfered at one time through the numerical control chamfering machine, the efficiency is high, the degree of automation is high, and the cost is low.

[0027] Those skilled in the art should know: although the present application has been described according to the above specific embodiments, the inventive idea of the present application is not limited to this invention, any modification using the inventive idea will be included in the protection scope of the present patent.
