[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the specification drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a device for facilitating the adjustment of the bevel angle, including a base 1, a first fixing plate 2 is fixedly connected to one end surface of the base 1, a first connecting plate 3 is fixedly connected to one end surface of the first fixing plate 2, a second fixing plate 5 is fixedly connected to one end surface of the first connecting plate 3, another first connecting plate 3 is fixedly connected to one end surface of the second fixing plate 5, two fourth fixing plates 20 are fixedly connected to the bottom end surface of the second fixing plate 5, a handwheel 4 is rotatably connected to one end surface of one fourth fixing plate 20, a lead screw 6 is fixedly connected to one end surface of the handwheel 4, a slide plate 14 is threadedly connected to one side of the lead screw 6, a rotating plate 7 is rotatably connected to one end surface of the slide plate 14, a fixed block 15 is rotatably connected to one end surface of the rotating plate 7, an adjusting plate 13 is fixedly connected to one end surface of the fixed block 15, the adjusting plate 13 is rotatably connected to the first connecting plate 3, and a moving component is arranged on one end surface of the adjusting plate 13.

[0022] Specifically, the rotation of the handwheel 4 drives the rotation of the lead screw 6. Since a nut adapted to the lead screw 6 is arranged inside the slide plate 14, the slide plate 14 can perform linear motion. Because the rotating plate 7 is rotatably connected to the slide plate 14 and the fixed block 15, and the fixed block 15 is arranged on one side of the adjusting plate 13, the adjusting plate 13 can rotate at a certain angle. Also, since the tool holder 17 is arranged on the adjusting plate 13, the tool can be adjusted according to the bevel angle of the PCB board, and the offset of the tool can be prevented.

[0023] The moving component includes a cylinder 16, a tool holder 17 and a slide rail 18. A cylinder 16 is fixedly connected to one end surface of the adjusting plate 13, two slide rails 18 are fixedly connected to one end surface of the adjusting plate 13, the output end of the cylinder 16 is fixedly connected to a third fixing plate 19, a tool holder 17 is fixedly connected to one end surface of the third fixing plate 19, and the tool holder 17 is slidably connected to the slide rail 18.

[0024] Specifically, the cylinder 16 pushes the tool holder 17 to move through the third fixing plate 19. The tool holder 17 can slide on the slide rail 18. Since the tool is installed on the tool holder 17, the tool can move. By cooperating with the adjustment of the angle of the adjusting plate 13, the processing position of the PCB board can be changed.

[0025] At the left part of the edge of one end surface of the adjusting plate 13, the second connecting plate 10 is fixedly connected. The first fixing knob 8 is arranged inside the second connecting plate 10. The second connecting plate 10 is rotatably connected with the first connecting plate 3.

[0026] Specifically, the first fixing knob 8 can rotate together with the second connecting plate 10. After the angle is adjusted, tighten the first fixing knob 8. The first fixing knob 8 can lock the second connecting plate 10 and the first connecting plate 3. The first connecting plate 3 can be fixed to the adjusting plate 13 to prevent the adjusting plate 13 from shaking during tool processing and affecting the processing effect.

[0027] At the middle part of the edge of one end surface of the adjusting plate 13, the third connecting plate 12 is fixedly connected. The second fixing knob 11 is arranged inside the third connecting plate 12. The third connecting plate 12 is rotatably connected with the first connecting plate 3.

[0028] Specifically, the rotation amplitude of the third connecting plate 12 is smaller than that of the second connecting plate 10. The second fixing knob 11 also plays a role in locking the adjusting plate 13 and the first connecting plate 3.

[0029] An arc-shaped groove 9 is opened inside the first connecting plate 3. The first fixing knob 8 is slidably connected with the first connecting plate 3 through the arc-shaped groove 9.

[0030] Specifically, the arc-shaped groove 9 can limit the rotation amplitude of the first fixing knob 8, and further limit the rotation of the adjusting plate 13.

[0031] A number of mounting holes are opened inside the tool holder 17, and a number of mounting holes are opened inside the base 1.

[0032] Specifically, the mounting holes on the tool holder 17 can install tools, and the mounting holes of the base 1 can be connected to others to increase the area of the bottom of the device, and further ensure the installation stability of the device.

[0033] One end surface of the slide plate 14 is slidably connected with the bottom end surface of the second fixing plate 5. One end surface of the lead screw 6 is rotatably connected with a fourth fixing plate 20. This setting ensures the stable operation of the slide plate 14.

[0034] Working principle: Rotate the first fixed knob 8 and the second fixed knob 11 to loosen the adjusting plate 13 and the first connecting plate 3. Rotate the handwheel 4, and the handwheel 4 can drive the lead screw 6 to rotate, and then the sliding plate 14 linearly moves. Due to the connection of the rotating plate 7, the adjusting plate 13 can rotate. Then twist the first fixed knob 8 and the second fixed knob 11 to lock the adjusting plate 13 and the first connecting plate 3, so that the tool can better fit the bevel angle of the PCB board; If a skip cut is required, start the cylinder 16, and the cylinder 16 can push the tool holder 17 to move, and cooperate with the angle adjustment to complete the skip cut action.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
