Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, specifically a multi-degree-of-freedom waterjet cutting robot. Background Technology

[0002] Waterjet cutting, also known as waterjet cutting, is a high-pressure water jet cutting technology that uses high-pressure water jets for cutting. Under computer control, it can carve workpieces in any shape and is less affected by material properties. Due to its low cost, ease of operation, and high yield rate, waterjet cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

[0003] In practical applications, existing waterjet cutting robots typically use robotic arms to adjust the angle of the waterjet, but this structure is too complex, making maintenance and repair difficult. Therefore, a multi-degree-of-freedom waterjet cutting robot is needed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-degree-of-freedom waterjet cutting robot that solves the problems mentioned in the background art.

[0005] This application provides a multi-degree-of-freedom waterjet cutting robot, including a base. A protective box and a water tank are fixedly connected to the top of the base. The water tank is located on one side of the protective box. A first motor is installed inside the protective box. The output shaft of the first motor passes through the outside of the protective box and is fixedly connected to a support plate. A support column is fixedly connected to the top of the support plate. A second motor is installed on one side of the support column. A crossbeam is fixedly connected to the side of the support column away from the second motor. The output shaft of the second motor passes through the support column and into the inside of the crossbeam, and is fixedly connected to a lead screw. A slider is threaded on the lead screw. An electric push rod is fixedly connected to the bottom end of the slider. A mounting bracket is fixedly connected to the bottom end of the electric push rod. A water jet is installed on the mounting bracket. A water pump is installed at the top of the water tank. A second water pipe is fixedly connected to the pump's suction end and inserted into the water tank. A first water pipe is fixedly connected to the pump's discharge end and is fixedly connected to the water jet.

[0006] In use, the output shaft of the second motor drives the lead screw to rotate. When the lead screw rotates, it converts the rotational motion of the slider into linear motion, thereby driving the water jet to move laterally. The electric push rod can adjust the height of the water jet, while the first motor can adjust the angle of the water jet. Through the cooperation of the above structures, the water jet's degree of freedom can be adjusted. The water pump can draw water from the water tank into the water jet through the first and second water pipes, and the water jet sprays out to complete the water cutting.

[0007] Optionally, the bottom end of the crossbeam is provided with a groove along the length direction that is adapted to the slider.

[0008] By adopting the above technical solution, the sliding of the slider is facilitated.

[0009] Optionally, a fixing frame is fixedly connected to the outer wall of the housing of the electric push rod, and a limiting block is fixedly connected to the bottom end of the fixing frame. The limiting block is sleeved on the outside of the first water pipe.

[0010] By adopting the above technical solution, it is beneficial to limit the end of the first water pipe near the water jet, so as to prevent the first water pipe from being located below the water jet when it is bent, thus avoiding cutting the first water pipe.

[0011] Optionally, the limiting block has a circular hole with a diameter larger than that of the first water pipe, and a rubber pad is attached to the inner wall of the limiting block.

[0012] By adopting the above technical solution, the friction between the limiting block and the surface of the first water pipe can be reduced.

[0013] Optionally, universal self-locking wheels are installed at the four corners of the bottom of the base.

[0014] By adopting the above technical solution, it is beneficial to move the equipment.

[0015] Optionally, the mounting bracket has a U-shaped structure.

[0016] The above technical solution facilitates the installation of water jets.

[0017] Optionally, both the first and second water pipes are flexible hoses.

[0018] By adopting the above technical solution, it is beneficial to bend the first and second water pipes, thereby improving the flexibility of use.

[0019] Optionally, the front wall of the water tank is provided with an observation window.

[0020] By adopting the above technical solution, it is easier to observe the amount of water inside the water tank.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses the output shaft of the second motor to drive the lead screw to rotate. When the lead screw rotates, it can convert the rotational motion of the slider into linear motion, thereby driving the water jet to move laterally. The electric push rod can adjust the height of the water jet, and the first motor can adjust the angle of the water jet. Through the cooperation of the above structures, the water jet can be adjusted in degrees of freedom. The structure is simple and easy to maintain. Attached Figure Description

[0031] In the technical solution of this utility model, such as Figure 1 As shown, a fixed frame 16 is fixedly connected to the outer wall of the housing of the electric push rod 7. A limiting block 17 is fixedly connected to the bottom end of the fixed frame 16. The limiting block 17 is sleeved on the outside of the first water pipe 11. This helps to limit the end of the first water pipe 11 that is close to the water jet 9, so as to prevent the first water pipe 11 from being located below the water jet 9 when it is bent, and to prevent the first water pipe 11 from being cut.

[0032] In the technical solution of this utility model, such as Figure 4 As shown, a circular hole is provided on the limiting block 17, the diameter of which is larger than the diameter of the first water pipe 11.

[0036] In the technical solution of this utility model, such as Figure 1 As shown, an observation window is provided on the front wall of the water tank 10; this facilitates observation of the water volume inside the water tank 10.

[0037] In use, the output shaft of the second motor 4 drives the lead screw 19 to rotate.
