Description

Technical Field

[0002] Waterjet cutting, also known as water knife, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water jet cutting. The waterjet cutting machine is one of the most productive machines in the world. It can carve workpieces at will under the control of a computer and is less affected by the texture of the material.

[0003] In the current existing technology, water jet cutting machines generally include a frame, a workbench, a slide rail, a transverse screw, a motor, a water tank, a nozzle and other components. The screw and the motor can be used to adjust the position of the cutting blade of the water jet cutting machine. In actual use, for the three-dimensional cutting of complex-shaped objects, due to the fact that the angle of the nozzle of the existing water jet cutting machine is fixed and the nozzle can only achieve radial position adjustment, the operator needs to stop the machine several times during the actual cutting process to adjust the placement of the object, so as to adapt to the three-dimensional cutting of complex-shaped objects.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 8 As shown, a water jet cutting machine that is easy to adjust the angle according to an embodiment of the present invention comprises a bottom plate 1;

[0037] A support mechanism 2 is fixedly mounted on one side of the base plate 1;

[0038] An adjustment mechanism 3 is fixedly installed on the top of the support mechanism 2 for adjusting the cutting angle;

[0039] A clamping mechanism 4 is slidably mounted on the top of the bottom plate 1 for clamping the cutting piece;

[0040] A collecting mechanism 5 is fixedly mounted at the bottom of the bottom plate 1 to collect water after cutting;

[0041] The support mechanism 2 includes a first support plate 21, which is fixedly mounted on one side of the bottom plate 1. A first groove 211 is provided on the top of the first support plate 21, and a second support plate 22 is slidably mounted on the inner surface of the first groove 211. A third support plate 23 is fixedly mounted on the top of the second support plate 22. A second groove 231 is provided in the middle of the third support plate 23, and two support rods 35 are rotatably mounted on both sides of the second groove 231. A T-shaped groove 351 is provided on one side of the support rod 35 located in the middle of the third support plate 23, and a second rack 352 is fixedly mounted on one side of the support rod 35. A cutting mechanism 39 is slidably mounted on the inner surface of the T-shaped groove 351.

[0042] The cutting mechanism 39 includes a T-shaped slider 391, which is slidably mounted on the inner surface of the T-shaped groove 351. A support block 392 is fixedly mounted on one side of the T-shaped slider 391. The support block 392 near the second rack 352 is provided with a fifth groove 394. The other side of the support block 392 is provided with a fourth groove 393. A second motor 395 is fixedly mounted on the support block 392 near the support rod 35. The output shaft of the second motor 395 is fixedly connected to a second gear 3951. The second gear 3951 is meshed with the second rack 352, and a fourth support plate 396 is fixedly installed on the other side of the support block 392. A third motor 397 is fixedly installed on one side of the fourth support plate 396. The output shaft of the third motor 397 passes through the fourth support plate 396 and does not contact the fourth support plate 396. The output shaft of the third motor 397 is fixedly connected to a connecting ring 398, and a water jet nozzle 399 is fixedly installed on the inner surface of the connecting ring 398. One end of the water jet nozzle 399 is fixedly connected to a water inlet pipe 3991.

[0043] When three-dimensional cutting is performed on the object to be cut, since the nozzle of the existing water jet cutting machine can only adjust the position radially, it can only meet the radial cutting of the object to be cut. If three-dimensional cutting is required, it is necessary to stop the machine to adjust the placement of the object to be cut, resulting in a long cutting cycle and a high cutting risk. As an embodiment of the present invention, the object to be cut is first placed on the base plate 1, and the clamping mechanism 4 clamps and fixes the object to be cut. The second support plate 22 can slide on the inner surface of the first groove 211. When the second support plate 22 slides on the inner surface of the first groove 211, the height of the water jet nozzle 399 can be adjusted, that is, the support mechanism 2 can adjust the height of the water jet nozzle 399 according to the shape of the object to be cut. When the water jet nozzle 399 needs to be adjusted When the water jet nozzle 399 is in a vertical position, the second motor 395 drives the second gear 3951 to rotate along the second rack 352. During this process, the second motor 395 drives the bottom support block 392 to move in the vertical direction, thereby achieving the purpose of adjusting the vertical movement of the water jet nozzle 399. When the water jet nozzle 399 needs to perform deflection cutting, the third motor 397 drives the connecting ring 398 to rotate. When the connecting ring 398 rotates, it drives the water jet nozzle 399 to deflect the angle, thereby achieving the purpose of adjusting the cutting angle of the water jet nozzle 399. When performing three-dimensional cutting on the object to be cut, there is no need to frequently stop the machine to adjust the placement posture of the object to be cut, thereby improving the cutting efficiency and reducing the risks caused by frequent stoppages.

[0044] The clamping mechanism 4 can fix the object to be cut on the base plate 1 to prevent the water sprayed from the water jet nozzle 399 from changing the position of the object and causing damage to the object during the cutting process. The collecting mechanism 5 can collect the water used for cutting, thereby facilitating subsequent treatment of the waste water.

[0045] like Figure 2 As shown, a plurality of electric telescopic rods 212 are fixedly installed at the bottom of the inner surface of the first groove 211 , and a second support plate 22 is fixedly connected to the top of the electric telescopic rod 212 .

[0046] Furthermore, since the shape of the cutting object is not fixed, the water cutting device needs to adjust the position of the water jet nozzle 399 according to the shape of the object and the cutting position. In order to ensure the safety of the operator, the general water cutting machine will shut down the water cutting machine when adjusting the position of the object to be cut, which reduces the working efficiency. As an embodiment of the present invention, a plurality of electric telescopic rods 212 work in the inner cavity of the first groove 211. When the plurality of electric telescopic rods 212 are retracted at the same time, the second support plate 22 is retracted into the first groove 211. At this time, the distance between the third support plate 23 and the bottom plate 1 is reduced, thereby reducing the distance between the water jet nozzle 399 and the object. When encountering a larger object, the electric telescopic rods 212 extend together to lift the third support plate 23 to increase the distance between the water jet nozzle 399 and the object.

[0047] like Figure 3 As shown, the adjusting mechanism 3 includes an annular support plate 31, which is fixedly mounted on one side of the third support plate 23. Annular grooves 311 are provided on both sides of the annular support plate 31. A first rack 312 is fixedly mounted on the inner surface of the annular support plate 31. A rotating shaft 36 is slidably mounted on the inner surfaces of the two annular grooves 311. The two rotating shafts 36 are respectively fixedly mounted on one side of two support rods 35. A first gear 37 is mounted on the opposite surfaces of the two support rods 35 for common rotation. A third groove 38 is provided in the middle of the first gear 37. A first motor 32 is fixedly mounted on the bottom of the third support plate 23. A pulley 33 is fixedly connected to the output shaft of the first motor 32. A belt 34 is wound around the outer surface of the pulley 33. The pulley 33 is located on one side of the second groove 231. The belt 34 runs through the second groove 231. The other end of the belt 34 is wound around the inner surface of the third groove 38.

[0048] Furthermore, when it is necessary to adjust the position of the water jet nozzle 399 in the horizontal direction according to the shape of the object to be cut, as an embodiment of the present invention, the first motor 32 drives the pulley 33 to rotate, the pulley 33 drives the belt 34 to rotate, and the belt 34 drives the first gear 37 to rotate through the third groove 38, and the first gear 37 is meshed with the first rack 312. Since support rods 35 are rotatably installed at both ends of the first gear 37, when the first gear 37 is meshed with the first rack 312, the first gear 37 will move around the annular support plate 31, and since the rotating shaft 36 is slidably installed on the inner surface of the annular groove 311, the water cutting device can adjust the position of the water jet nozzle 399 in the horizontal direction through the support rod 35.

[0049] like Figures 4 to 5As shown, the fifth groove 394 is used to enable the support block 392 to slide on the surface of the support rod 35 without being blocked by the second rack 352, and the water inlet pipe 3991 and the water jet nozzle 399 can both rotate in the inner cavity of the fourth groove 393, and the other end of the water inlet pipe 3991 is connected to a high-pressure water tank.

[0050] Furthermore, when the water jet cutting machine is working, the support block 392 needs to slide on the upper part of the second rack 352. As an embodiment of the present invention, through the design of the fourth groove 393, the water jet nozzle 399 can be adjusted in angle under the action of the third motor 397 and will not be blocked by the support block 392. The high-pressure water tank connected to the other end of the water inlet pipe 3991 can also supply water to the water jet nozzle 399 through the water inlet pipe 3991. Through the fifth groove 394, the support block 392 can avoid contact with the second rack 352, thereby enabling the support block 392 to slide stably.

[0051] like Figure 6 to Figure 7 As shown, the clamping mechanism 4 includes a slide groove 41, and the slide groove 41 is opened at the top of the base plate 1. Two clamps 42 are slidably installed on the top of the base plate 1. Square sliders 44 are fixedly installed at the bottom of the two clamps 42. Limit blocks 45 are fixedly installed at the bottom of the square sliders 44. Triangular clamps 43 are fixedly installed on the opposite surfaces of the two clamps 42. The square sliders 44 are slidably installed on the inner surface of the slide groove 41. A threaded hole 46 is opened in the middle of the limit block 45. The inner surfaces of the two threaded holes 46 are threadedly connected with a bidirectional threaded rod 47.

[0052] During cutting, the object to be cut needs to be clamped and fixed. As an embodiment of the present invention, a bidirectional threaded rod 47 carries two limit blocks 45 to slide at the bottom of the base plate 1, so that a square slider 44 connected to the top of the limit block 45 slides on the inner surface of the slide groove 41, and then the square slider 44 can move with the clamping plate 42 fixed on the top to clamp the object. A number of triangular clamping blocks 43 installed between the opposite surfaces of the two clamping plates 42 can enable the clamping plates 42 to clamp the object more firmly, effectively preventing the object from being blown by the high-pressure water flow when being cut, thereby causing damage to the object.

[0053] like Figure 8 As shown, the collecting mechanism 5 includes a plurality of water leakage grooves 51, and the plurality of water leakage grooves 51 are opened on the top of the base plate 1. A water storage tank 52 is fixedly installed at the bottom of the base plate 1. A water leakage pipe 53 is opened at the bottom of the water storage tank 52, and a water valve 54 is fixedly installed in the middle of the water leakage pipe 53.

[0054] A large amount of water will be used during cutting. In order to collect the water after cutting, as an embodiment of the present invention, the water after cutting flows into the water storage tank 52 through the leakage trough 51. When the water cutting device is working, the water valve 54 is closed and the sewage is stored in the water storage tank 52. After the water storage tank 52 is full of sewage, the water valve 54 is opened and the sewage flows out through the leakage pipe 53. This design can prevent the sewage turbulence from affecting the movement of workers when they are working.

[0055] Working principle: firstly place the object to be cut on the top of the bottom plate 1, rotate the bidirectional threaded rod 47 to make the two clamps 42 move towards each other, the triangular clamp block 43 on the clamp plate 42 first contacts the object, and the clamp block 42 continues to move to clamp the object.

[0056] The first motor 32 drives the belt 34 through the pulley 33, and the belt 34 rotates with the first gear 37 through the third groove 38 on the first gear 37. The first gear 37 meshes with the first rack 312. Under the action of the support rod 35, the support rod 35 can rotate in the annular support plate 31. Under the action of the second motor 395 in the cutting mechanism 39, the T-shaped slider 391 can slide on the inner surface of the T-shaped groove 351, and the T-shaped slider 391 slides with the support block 392. Under the action of the third motor 397, the transmission shaft of the third motor 397 rotates with the connecting ring 398, and the connecting ring 398 rotates with the water jet nozzle 399. Due to the action of the fourth groove 393, the water jet nozzle 399 can rotate 180°.

[0057] The support mechanism 2 controls the second support plate 22 to slide on the inner surface of the first groove 211 through a number of electric telescopic rods 212, and can adjust the distance between the third support plate 23 and the base plate 1, thereby achieving the purpose of controlling the distance between the water jet nozzle 399 and the object. When cutting the object, the water used for cutting will flow through the leakage trough 51 to the water storage tank 52 after cutting the object to collect the sewage.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
