DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-4 As shown, a numerically controlled adjustable angle cutting mechanism is provided in one embodiment of the utility model, comprising:

[0032] Fixed rack 02;

[0033] A movable frame 03 is rotatably arranged on the fixed frame 02, and an adjustment rail 31 is arranged on the movable frame 03;

[0034] The main and auxiliary cutting saw groups 01 are mounted on a movable frame 03;

[0035] The lifting structure is arranged between the main and auxiliary cutting saw assemblies 01 and the movable frame 03, and is used to drive the main and auxiliary cutting saw assemblies 01 to move;

[0036] The angle adjustment structure is installed on the fixed frame 02 and is used to drive the movable frame 03 to rotate along the adjustment track 31.

[0037] In the embodiment of the utility model, the numerically controlled adjustable angle cutting mechanism is installed on the equipment through the drag chain 06, the operation of each structure is controlled by the control center of the equipment, and the lateral movement of the numerically controlled adjustable angle cutting mechanism is achieved by the equipment driving the drag chain 06 to move.

[0038] The cutting angles of the main and auxiliary cutting saw groups 01 can be automatically adjusted by setting the angle adjustment structure, and the angle adjustment is accurate, and the mechanism is flexible and reliable.

[0039] like Figure 3 As shown, as a preferred embodiment of the utility model, the angle adjustment structure includes:

[0040] Adjust the servo motor 41, which is rotatably mounted on the fixed frame 02;

[0041] The trapezoidal lead screw 42 , the output end of the regulating servo motor 41 is fixedly connected to the trapezoidal lead screw 42 through a coupling, and the trapezoidal lead screw 42 is threadedly connected to the movable frame 03 .

[0042] In the embodiment of the utility model, the adjustment servo motor 41 drives the trapezoidal screw 42, and the trapezoidal screw 42 converts the rotational motion of the adjustment servo motor 41 into linear motion, thereby pushing the main and auxiliary cutting saw sets 01 to the specified angle position through the movable frame 03, and performing an angle change of 0 to 45 degrees. After the angle adjustment is completed, the main and auxiliary cutting saw sets 01 are locked in this position, and at this time, the adjustment servo motor 41 and the trapezoidal screw 42 no longer move.

[0043] like Figure 1-4 As shown, as a preferred embodiment of the utility model, the lifting structure includes a lifting cylinder 05, and the lifting cylinder 05 is installed on the movable frame 03 and connected to the main and auxiliary cutting saw groups 01.

[0044] like Figure 2-4 As shown, as a preferred embodiment of the utility model, the main and auxiliary cutting saw set 01 includes:

[0045] The lifting seat 11 is slidably arranged on the movable frame 03; the lifting seat 11 is fixedly connected with a slider 17, the movable frame 03 is fixedly connected with a linear guide rail 32, and the slider 17 is slidably connected with the linear guide rail 32;

[0046] The main saw blade 12 and the auxiliary saw blade 13 are both mounted on the lifting seat 11;

[0047] The main saw motor seat 14 and the auxiliary saw motor seat 15 are both mounted on the lifting seat 11;

[0048] The main cutting motor is mounted on the main saw motor seat 14 and is used to drive the main saw blade 12 to operate;

[0049] The auxiliary cutting motor is mounted on the auxiliary saw motor base 15 and is used to drive the auxiliary saw blade 13 to operate.

[0050] In the embodiment of the utility model, the main saw blade 12 and the auxiliary saw blade 13 are controlled separately, and can cut simultaneously or separately. When the lifting seat 11 moves relative to the movable frame 03, the slide block 17 slides on the linear guide rail 32 to play a guiding role.

[0051] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, both sides of the lifting seat 11 are fixedly connected with L-shaped connecting plates 16, and the output end of the lifting cylinder 05 is connected to the L-shaped connecting plate 16.

[0052] In the embodiment of the utility model, the cylinder drive is adopted, and the response is fast. The lifting cylinder 05 drives the lifting seat 11 to rise or fall through the L-shaped connecting plate 16, and then drives the main saw blade 12 and the auxiliary saw blade 13 to rise or fall. When the control center starts cutting, the lifting cylinder 05 drives the main saw blade 12 and the auxiliary saw blade 13 to rise, and the control center drives the drag chain 06 to make the whole mechanism move horizontally, and then the main saw blade 12 and the auxiliary saw blade 13 move horizontally to complete the cutting.

[0053] The working principle of the utility model is:

[0054] When the numerically controlled adjustable angle cutting mechanism is used, the operator inputs the cutting angle size into the control interface of the whole machine. When the control center starts cutting, the servo motor 41 is adjusted to drive the trapezoidal screw 42. The trapezoidal screw 42 converts the rotational motion of the servo motor 41 into linear motion, thereby pushing the main and auxiliary cutting saw groups 01 to the specified angle position through the movable frame 03, and performing an angle change of 0 to 45 degrees. After the angle adjustment is completed, the lifting cylinder 05 drives the main saw blade 12 and the auxiliary saw blade 13 to rise, and the control center drives the drag chain 06 to make the whole mechanism move horizontally, and then the main saw blade 12 and the auxiliary saw blade 13 move horizontally to complete the cutting. After the cutting is completed, the main saw blade 12 and the auxiliary saw blade 13 are reset, and the main and auxiliary cutting saw groups 01 are reset.

[0055] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
