Detailed Description

The arbitrary angle rotary cutting device of the display base bracket of the present invention is further described with reference to fig. 1 to 3.

The utility model provides an arbitrary angle of display base support rotary cutting device which characterized by: comprises a workbench 1, a guide rail 17, a panel 2, a turntable bearing 3 and a lifting cutting mechanism.

The workbench 1 is provided with a central hole, the inner wall of the central hole is provided with a step, and the edge of the central hole is provided with an angle size 15;

the panel 2 is mounted on a step in the central bore by means of a turntable bearing 3 and the panel 2 has a rectangular cut-out relief opening 18.

The guide rail 17 is mounted on the table 1 and extends through an escape opening 18.

The lifting type cutting mechanism comprises a lower support 4 arranged on the lower surface of the panel 2 through bolts, a sliding frame 6 which is matched with the lower support 4 in a vertical sliding mode, a motor 8 arranged on the sliding frame 6, a cutting wheel 9 arranged on an output shaft of the motor 8 and positioned right below the avoidance opening 18, and a first lifting driving part 5 driving the sliding frame 6 to move up and down. The lower bracket 4 is provided with a slide rail 7 extending up and down, and the sliding frame 6 is provided with a slide block which is in sliding fit with the slide rail 7.

When cutting, the section bar enters the cutting station under the guide of the guide rail 17, namely, the section bar is moved to the position of the avoiding opening 18, the motor 8 drives the cutting wheel 9 to rotate, the first lifting driving part 5 drives the sliding frame 6 and the cutting wheel 9 to move upwards, so that the cutting wheel 9 cuts the section bar through the avoiding opening 18, after the cutting is completed, the first driving part drives the sliding frame 6 and the cutting wheel 9 to move downwards, namely, the cutting wheel 9 moves to the lower part of the panel 2, the section bar which is not cut is continuously pushed to the position of the avoiding opening 18, and the circular cutting is realized. When the inclined plane of different inclinations needs to be cut, the panel 2 is rotated manually or through an external rotating mechanism, and the linkage lifting type cutting mechanism synchronously rotates to adjust the angle between the cutting wheel 9 and the guide rail 17, namely the section bar, and cut out the inclined plane of different angles to the section bar, so that the operation is simple and the efficiency is high. The operator can refer to the angle dimension 15 when rotating the panel 2, so as to improve the accuracy of the angle adjustment.

The embodiment is further configured as follows: the device also comprises an upper bracket 12, a second lifting driving part 13 and a shielding cover 14; the upper bracket 12 is arranged on the panel 2; the second lifting driving part 13 is arranged on the upper bracket 12; the shield cover 14 is connected to the second elevation driving member 13, and has a lower opening 141 vertically corresponding to the escape opening 18. When the section bar is cut, the shielding cover 14 covers the avoiding opening 18 to shield the scraps generated by cutting, so that the problem that the scraps splash everywhere is avoided.

The embodiment is further configured as follows: the lower opening 141 has a pressing portion 142 thereon. The pressing portion 142 is a thickening of the inner wall or the outer wall of the lower opening 141 of the shielding cover 14, and when the cutting wheel 9 cuts the profile, the second lifting driving part 13 drives the shielding cover 14 to move downwards, so that the pressing portion 142 presses on the upper surface of the profile to limit the profile and improve the cutting stability of the profile.
