[0002] The cutting head is a key component of the cutting equipment used to perform cutting operations. It consists of cutting tools (such as saw blades, blades, etc.), drive devices (such as motors, etc.) and related fixing and adjustment mechanisms. Different types of cutting heads are suitable for different cutting materials and cutting requirements, such as metal cutting heads, wood cutting heads, stone cutting heads, etc. The cutting head can cut and cut materials through rotation, reciprocating motion, etc. to achieve precise processing and separation of materials.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model provides a multi-directional rotating bevel cutting head. The cutting head can realize switching of multiple specific angles by prefabricating multiple limit holes.

[0027] The rotating assembly includes a rotating base 21 mounted on the frame 4. A rotating shaft 25 is provided inside the rotating base 21 for rotation. A gear 24 is fixed on the top of the rotating shaft 25. A motor 22 is installed on one side of the top of the rotating base 21. The rotating shaft at the bottom of the motor 22 extends into the rotating base 21 and is fixed with a gear 1 23. Gear 1 23 is located on one side of gear 2 24 and is meshed with gear 2 24.

[0028] The tilt drive assembly includes a cylinder double-ear base 12 fixed on both sides of the top of the U-shaped bracket mounting plate 1, the bottom end of the cylinder double-ear base 12 is hinged with a cylinder single-ear base 11, the bottom of the cylinder single-ear base 11 is fixed with a cylinder body 17, the output end of the cylinder body 17 is fixed with a cylinder Y-shaped joint 10, and a rocker arm 1 8 is hinged on the cylinder Y-shaped joint 10, and the rocker arm 1 8 is fixed to the top of the A-axis pin shaft 2, and the bottom of the A-axis pin shaft 2 is fixed with a rocker arm 2 9, and the rocker arm 1 8 is fixed to the rocker arm 2 9.

[0029] A U-shaped bracket front baffle 16 is fixed to the front of the U-shaped bracket mounting plate 1, a saw blade cover 7 is provided on the outside of the saw blade body 20, and two groups of rocker arm 18, cylinder Y-shaped joint 10, cylinder body 17, cylinder single-ear base 11 and cylinder double-ear base 12 are provided. The two groups of rocker arm 18, cylinder Y-shaped joint 10, cylinder body 17, cylinder single-ear base 11 and cylinder double-ear base 12 are symmetrical on both sides of the center line of the U-shaped bracket mounting plate 1.

[0030] Working Principle: The main components of the cutting head are composed of a U-shaped bracket mounting plate 1, a main shaft body 6 and a saw blade body 20. The cutting head can be mounted on the rotating base 21 by fixing the rotating shaft 25 to the top of the U-shaped bracket mounting plate 1.

[0031] Figure 1 The cutting head is in a state of being tilted at 45 degrees. At this time, the limit pile 15 and the bolt 19 are fixed to the hole position of the 45-degree limit hole 151. The top of the spindle mounting plate 5 conflicts with the bottom of the bolt 19. The bolt 19 limits the tilt of the spindle mounting plate 5, so that the maximum tilt angle of the spindle mounting plate 5 is maintained at 45 degrees. It should be noted that the fixing piece is inserted into the fixing hole 152 and the limit hole 151 to fix the limit pile 15 to the inner of the U-shaped bracket mounting plate 1. On the wall, the position of the fixing hole 152 opened in the limiting pile 15 is aligned with the limiting hole 151 at different positions and fixed with a connecting piece, so that the limiting angle of the limiting pile 15 on the spindle mounting plate 5 can be adjusted in conjunction with the bolt 19. The limiting hole 151 positions corresponding to 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, and 45 degrees can be pre-designed and prefabricated in advance. According to actual needs, the limiting pile 15 and the bolt 19 can be installed on the hole positions of different degrees to achieve the limit position of different degrees;

[0032] When the cylinder body 17 is started, the cylinder body 17 pushes down the rocker arm 8 to drive the A-axis pin 2 to rotate, and the A-axis pin 2 drives the U-shaped bracket bearing seat 3 and the connecting shaft 18 to rotate. At this time, the spindle mounting plate 5 rotates with the connecting shaft 18 as the axis, and the inclination angle of the spindle body 6 fixed on the spindle mounting plate 5 and the saw blade body 20 at its end will continue to decrease, and the inclination will make the saw blade body 20 form a certain angle with the stone surface to achieve a bevel cutting effect. Among them, the rotation of the A-axis pin 2 will drive the scale pointer 14 to rotate accordingly, and the arrow part of the scale pointer 14 points to the angles corresponding to different scales on the arc scale 13 to indicate the inclination angle of the saw blade body 20. The scale pointer 14 is used in conjunction with the arc scale 13 to indicate the inclination degree of the saw blade body 20, so as to ensure that the staff observes whether the inclination angle of the saw blade reaches the required angle for processing, and prevent the inclination angle of the saw blade body 20 from being incorrect and affecting the processing;

[0033] On the contrary, the cylinder body 17 pulls up the rocker arm 8, driving the A-axis pin 2, the U-shaped bracket bearing seat 3, and the connecting shaft 18 to rotate in reverse, and the spindle mounting plate 5 rotates with the connecting shaft 18 as the axis. The inclination angle of the spindle body 6 fixed to the spindle mounting plate 5 and the saw blade body 20 at its end will continue to increase;

[0034] The starting motor 22 drives the gear 1 23 to rotate, and the gear 1 23 drives the gear 2 24 to rotate to rotate the rotating shaft 25. The rotating rotating shaft 25 drives the U-shaped bracket mounting plate 1 to rotate, so that the cutting head can rotate left and right in the horizontal direction around the vertical axis to change the cutting direction and cut edges or shapes of different angles on the stone. For example, when cutting a polygonal stone countertop, the rotating head can easily cut out each bevel.
