[0002] Waterjet cutting machine is a very important industrial processing equipment, which can cut various materials through high-pressure water flow and abrasives. With the continuous development of science and technology, waterjet cutting machine is also constantly upgraded, and the most important one is the five-axis control system. At present, there are two main five-axis control systems on the market: AC and AB. AC five-axis means that the A-axis and C-axis rotate at the same time, and the B-axis moves along the Y-axis direction; AB five-axis means that the A-axis and B-axis rotate at the same time, and the C-axis moves.

[0003] Taking the low-cost AB five-axis water jet cutting machine as an example, the water jet cutting head is installed on the B axis and rotates around the B axis. The B axis is installed on the A axis and rotates around the A axis. The A axis is installed on the Z axis and rises and falls along the Z axis. The common A axis mounting seat is relatively short, so the distance between the A axis and the Z axis is too close. When the B axis drive motor rotates around the A axis, it is easy to interfere with the Z axis protective housing above the machine tool, causing the Z axis protective housing to be damaged.

[0004] Therefore, it is necessary to provide a water jet cutting head to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0026] like Figure 1-5 As shown, the water jet cutting head provided by the utility model comprises: a mounting frame 9 mounted on a water jet cutting machine body, a lifting frame 10 is mounted on one side of the mounting frame 9, the lifting frame 10 is lifted vertically and used as a Z axis, an A axis mounting seat 1 is mounted at the bottom of the lifting frame 10, the A axis mounting seat 1 is exposed from the lifting frame 10 for a long length, and an A axis body 2 and a first driving motor 3 for driving the A axis body 2 to rotate are obliquely mounted on the A axis mounting seat 1, a curved B axis mounting seat 4 is mounted on the A axis body 2, a B axis body 5 and a second driving motor 6 for driving the B axis body 5 to rotate are obliquely mounted on the B axis mounting seat 4, a cutter head fixing fixture 7 is mounted at one end of the B axis body 5, a water jet cutting head body 8 is clamped and mounted on the cutter head fixing fixture 7, when in use, the A axis is driven to rotate by the first driving motor 3, and the B axis is driven to rotate by the second driving motor 6, so that the water jet cutting head body 8 can be controlled to rotate within a certain angle range, and the water outlet direction of the water jet cutting head body 8 can be adjusted, so as to cut complex parts. The lifting frame 10 is raised to adjust the height of the water jet cutting head body 8 to achieve the adjustment of its Z axis. Since the A-axis mounting seat 1 is longer, when the A-axis body 2 rotates, the second drive motor 6 at one end of the B-axis body 5 rotates and when it is raised to the highest point, it will not interfere with the upper casing, and it is safer to use.

[0027] By setting a long A-axis mounting seat 1 and installing the A-axis body 2 at an angle, installing a curved B-axis mounting seat 4 at the end of the A-axis body 2, and installing the B-axis body 5 at an angle on the B-axis mounting seat 4, when the A-axis body 2 rotates, the second drive motor 6 at one end of the B-axis body 5 rotates around the A-axis body 2 without interfering with the upper Z-axis protective casing, making it safer to use.

[0028] Embodiment 2:

[0029] like Figure 5 As shown, a mounting cavity 13 is provided in the lifting frame 10, and the top end of the A-axis mounting seat 1 is inserted into the mounting cavity 13. A clamping mechanism is provided on the lifting frame 10, and the clamping mechanism is used to clamp and fix the A-axis mounting seat 1 inserted into the mounting cavity 13. The clamping mechanism includes a hydraulic cylinder 12 installed on the lifting frame 10, and a pull rod 11 is installed at the bottom end of the hydraulic cylinder 12. Two special-shaped rods 14 are symmetrically installed on the pull rod 11. A clamping head 16 is installed on the inner side of the special-shaped rod 14. The clamping head 16 is pressed tightly against the side of the A-axis mounting seat 1, and the special-shaped rod 14 and the lifting frame A linkage rod 15 is installed between 10, and both ends of the linkage rod 15 are rotatably connected with the special-shaped rod 14 and the lifting frame 10. When in use, the hydraulic cylinder 12 is started to shorten its output shaft, thereby raising the pull rod 11. The raising of the pull rod 11 drives the special-shaped rod 14 to rise, and then under the action of the linkage rod 15, the lower ends of the special-shaped rod 14 are brought close to each other and raised a little, so that the two clamping heads 16 are brought close to each other, and then the A-axis mounting seat 1 entering the mounting cavity 13 is clamped and fixed in the mounting cavity 13, completing the connection and fixation of the A-axis mounting seat 1.

[0030] By providing the installation cavity 13, the pull rod 11, the hydraulic cylinder 12, the special-shaped rod 14, the linkage rod 15 and the clamping head 16, and using the hydraulic cylinder 12 to drive the two clamping heads 16 to approach each other, the A-axis mounting seat 1 can be conveniently fixed to the bottom of the lifting frame 10.

[0031] Embodiment 3:

[0032] like Figure 5 As shown, a spring 17 is installed in the installation cavity 13. When in use, the top of the A-axis mounting seat 1 is inserted into the installation cavity 13 until its top abuts against the bottom of the spring 17. At this time, the installation height is reached, and the hydraulic cylinder 12 can be started to fix the A-axis mounting seat 1. When fixing, the A-axis mounting seat 1 is slightly raised, and the A-axis mounting seat 1 is clamped and slightly raised, thereby compressing the spring 17. When the clamping head 16 clamps the A-axis mounting seat 1 and lifts it up, the elasticity of the spring 17 is used to make the bottom end of the spring 17 tightly abut against the top of the A-axis mounting seat 1, thereby applying a downward force to the A-axis mounting seat 1. During cutting, the reaction force generated pushes the A-axis mounting seat 1 to have an upward trend. Under the action of the spring 17, the A-axis mounting seat 1 is not easy to slide with the clamping head 16.

[0033] The spring 17 is installed in the installation cavity 13 , and the installation height of the A-axis installation seat 1 is positioned by using the spring 17 , so that the A-axis installation seat 1 is more stable.

[0034] Embodiment 4:

[0035] like Figure 4-5 As shown, a track 19 is installed on one side of the mounting frame 9, and a slider 20 that slides up and down is installed on the track 19. The slider 20 is connected to the lifting frame 10. When in use, the lifting frame 10 is raised or lowered, driving the slider 20 to slide on the track 19. Through the cooperation between the slider 20 and the track 19, the lifting frame 10 is more stable when being raised or lowered.

[0036] By providing the track 19 and the slider 20 , the cooperation between the slider 20 and the track 19 can make the lifting frame 10 more stable during lifting.

[0037] Embodiment 5:

[0038] like Figure 4-5 As shown, an electric push rod 18 is installed on the mounting frame 9, and the output shaft of the electric push rod 18 is connected to the lifting frame 10. When in use, the electric push rod 18 is started to shorten its output shaft, thereby raising the lifting frame 10, and vice versa, the lifting frame 10 is lowered.

[0039] By installing the electric push rod 18 on the mounting frame 9, the lifting and lowering of the lifting frame 10 can be conveniently controlled.

[0040] Working principle: When in use, the A-axis is driven to rotate by the first drive motor 3, and the B-axis is driven to rotate by the second drive motor 6, so that the water jet cutting head body 8 can be controlled to rotate within a certain angle range, and the water outlet direction of the water jet cutting head body 8 can be adjusted to cut complex parts. The lifting frame 10 is raised to adjust the height of the water jet cutting head body 8 to achieve the adjustment of its Z axis. Since the A-axis mounting seat 1 is relatively long, when the A-axis body 2 rotates, the second drive motor 6 at one end of the B-axis body 5 rotates, and when it is raised to the highest point, it will not interfere with the upper casing, and it is safer to use.
