The positioning unit is used to position the table top to be processed, and the clamping unit can press the table top to be processed onto the positioning unit to prevent movement during the processing and affect the processing quality.

[0026] The clamping mechanism is arranged on the frame 1 and is used for positioning and clamping the table top. The frame 1 is provided with a chamfering mechanism for chamfering the table top, and the chamfering mechanism is connected with a lifting mechanism and a lateral moving mechanism.

[0027] The chamfering mechanism includes an end chamfering unit for chamfering two adjacent side surfaces on the table top. The number of the end chamfering units can be adjusted as needed, and can be one, two, or three or more. In the present embodiment, four are used as an example for illustration.

[0028] The distribution positions of the four end chamfering units are set corresponding to the required chamfering positions, and two are in a group, which are divided into two groups. The two groups of end chamfering units are respectively set on the lifting mechanism. At least one end chamfering unit in each group of end chamfering units is connected to the lifting mechanism through a position adjustment unit, so that the chamfering position can be adjusted in this direction.

[0029] The end chamfering unit includes a milling cutter 14 for chamfering the table top. The contour lines on both sides of the side projection of the milling cutter 14 are arc-shaped or "〔"-shaped. The table top is chamfered by rotating the milling cutter 14.

[0030] The milling cutter 14 is driven to rotate by a motor 12 , and the motor 12 can be directly fixedly mounted on the bracket 3 or the position adjustment unit, or can be connected to the bracket 3 or the position adjustment unit through a mounting seat.

[0031] The chamfering mechanism is connected with a dust suction mechanism, which can collect debris generated during the chamfering process.

[0032] The dust suction mechanism includes a dust suction port connected to a dust suction device body. The dust suction port is divided into an upper dust suction port 13 and a lower dust suction port 15. One or both of the two ports can be selected according to needs during specific use.

[0033] The upper dust suction port 13 is located obliquely above one of the end chamfering units in the same group, and the lower dust suction port 15 is located obliquely below the other end chamfering unit. In this way, the milling debris will move to the corresponding dust suction port, and the negative pressure generated by the vacuum cleaner can further promote the debris to be sucked away.

[0037] A sliding unit and a screw-nut mechanism are also provided between the second movable plate 5 and the bracket 3 , and the screw-nut mechanism drives the second movable plate 5 to slide on the bracket 3 through the sliding unit.

[0038] The brackets 3 are provided in pairs, one of which is driven to move by a transverse moving mechanism, and the other bracket 3 can be selectively connected to the same or another transverse moving mechanism as needed. The transverse moving mechanism drives the bracket 3 to move, thereby adjusting the distance between the two brackets 3.

[0039] The lateral movement mechanism includes a first moving plate 4 capable of driving the bracket 3 to move lateraly. A sliding unit and a screw-nut mechanism are also provided between the first moving plate 4 and the frame 1. The screw-nut mechanism drives the first moving plate 4 to slide on the frame 1 through the sliding unit.

[0040] The screw and nut mechanisms on the lateral moving mechanism, the lifting mechanism and the chamfering mechanism can be driven by a motor or manually as required.

[0041] The positioning unit includes a movable support frame 6 fixedly mounted on the first movable plate 4 and a fixed support frame 7 fixedly mounted on the frame 1 , and the movable support frame 6 and the fixed support frame 7 are used to support the table top to be processed.

[0042] At least two positioning columns 8 are arranged around the movable support frame 6 and the fixed support frame 7. The two positioning columns 8 abut against two non-coplanar side surfaces of the table top to determine the position. In the present scheme, three positioning columns 8 are arranged, two of which are respectively arranged on the frame 1 and the first movable plate 4 near one side of the corresponding movable support frame 6 and the fixed support frame 7, and the other is arranged on the frame 1 near one end of the table top to be processed.

[0043] The positioning column 8 is provided with a positioning strip 18 which abuts against the side of the table top to be processed, and the positioning strip 18 is connected to the positioning column 8 through an adjustment component.

[0045] The adjustable column 17 is provided with a hole for accommodating the bolt to pass through, and the hole is a long hole 19, and the length direction of the long hole 19 is perpendicular to the length direction of the adjustable column 17, so that it is convenient to adjust the adjustable column 17 forward and backward, and then adjust the front and rear position of the positioning bar 18.

[0046] The positioning column 8 is provided with a screw hole for use with one end of a corresponding bolt, so as to facilitate threaded connection with the bolt.

[0047] The pressing unit includes a telescopic part 2 that can press the table top to be processed. The telescopic part 2 is fixedly installed on the inner top wall of the frame 1. The telescopic part 2 can be a cylinder, an oil cylinder or an electric telescopic rod. The telescopic part 2 can extend to apply a certain pressure to the table top to be processed.
