Description

Technical Field

[0001] This utility model relates to the field of water jet technology, and in particular to a water jet device with a rotating mechanism. Background Technology

[0002] High-pressure abrasive waterjet cutting, also known as waterjet cutting, is a new technology developed using waterjet technology and high-speed grinding technology. Its principle is as follows: water is pressurized to 200–400 MPa, giving it enormous pressure energy, and then sent into a cutting nozzle with a very small orifice. Abrasive is then added, and the water and abrasive mix and are ejected at twice the speed of sound, creating a cutting effect on the stone workpiece.

[0003] Currently, existing waterjet cutter heads have a single cutting angle and cannot be rotated for adjustment, making them unsuitable for cutting complex workpieces. While some existing waterjet cutter heads on the market use multi-axis cutting, their movement and rotational freedom are limited. Therefore, in order to improve the effect of waterjet cutting and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing waterjet devices and application methods. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a water jet device with a rotating mechanism to solve the problems of the existing water jet head having a single cutting angle, not being able to be rotated and adjusted, and being difficult to adapt to the cutting of complex workpieces. Furthermore, some existing water jet heads on the market use multi-axis cutting, but their freedom of movement and rotation is limited.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water jet device with a rotating mechanism includes a rotating bracket. A mounting plate is rotatably connected to the bottom of the rotating bracket via a pin. A cutting head is inserted into the top of the mounting plate, and a cutting nozzle is fixedly connected to the bottom of the cutting head. A fastening nut is threaded onto the outer wall of the cutting nozzle and rests against the bottom of the mounting plate. A mounting hole is provided on one side of the rotating bracket. An electric push rod is rotatably connected between the inner walls of the two sides of the mounting hole via a pin. The other end of the electric push rod is rotatably connected to the top of the mounting plate via a pin. A mounting housing is provided on the top of the rotating bracket. A rotating sleeve is rotatably connected to the bottom of the mounting housing. A ring rack is fixedly connected to the top of the rotating sleeve. One outer wall of the rotating sleeve is fixedly connected to one end of the rotating bracket. A motor is fixedly connected to the top outer wall of the mounting housing. A gear is keyed to the output end of the motor, and the gear meshes with the ring rack.

[0006] Furthermore, a bearing is connected between the rotating sleeve and the bottom of the mounting housing via an interlocking connection.

[0007] Furthermore, a baffle is fixedly connected to the bottom of the fastening nut, and the baffle covers the cutting nozzle.

[0008] Furthermore, a high-pressure water pipe is sealed and inserted into the top of the cutting head.

[0009] Furthermore, the top of the mounting housing is provided with a through hole, through which a high-pressure water pipe passes.

[0010] Furthermore, a connector is sealed and inserted into one side of the cutting head, and an abrasive tube is sealed and inserted into the other end of the connector.

[0018] Reference Figures 1-3 A water jet device with a rotating mechanism includes a rotating bracket 1. The bottom end of the rotating bracket 1 is rotatably connected to a mounting plate 2 via a pin. A cutting head 3 is inserted into the top of the mounting plate 2. The mounting plate 2 is provided with a mounting groove that is compatible with the cutting head 3. An anti-slip pad is placed in the mounting groove. The bottom of the cutting head 3 is integrally formed with a cutting nozzle 4. The outer wall of the cutting nozzle 4 is threaded with a fastening nut 5. The fastening nut 5 is pressed against the bottom of the mounting plate 2, which facilitates the fixing of the cutting head 3 and the cutting nozzle 4. The rotating bracket 1 has a mounting hole 6 on one side. An electric push rod 7 is rotatably connected between the inner walls of the two sides of the mounting hole 6 via a pin. The other end of the electric push rod 7 is rotatably connected to the top of the mounting plate 2 via a pin seat. The mounting plate 2 is rotated under the drive of the electric push rod 7, which in turn drives the cutting head 3 and the cutting nozzle 4 to rotate, thereby adjusting the cutting pitch angle of the cutting nozzle 4. The top of the rotating bracket 1 is provided with a mounting housing 8; A rotating sleeve 9 is rotatably connected to the bottom through hole of the mounting housing 8. A bearing 11 is provided between the rotating sleeve 9 and the inner wall of the through hole of the mounting housing 8 so that the rotating sleeve 9 can rotate more smoothly. One side of the outer wall of the rotating sleeve 9 is welded and fixedly connected to one end of the rotating bracket 1. A ring rack 10 is welded to the top of the rotating sleeve 9. A motor 13 is fixed to the top outer wall of the mounting housing 8 by bolts. A gear 12 is keyed to the output end of the motor 13, and the gear 12 meshes with the ring rack 10. Driven by the motor 13, the gear 12 rotates, and the gear 12, in turn, meshes with the ring rack 10, which in turn drives the rotating sleeve 9 and the rotating bracket 1 to rotate, thereby driving the cutting head 3 and the cutting nozzle 4 to rotate, thus adjusting the cutting direction, which is between 0 and 180 degrees.

[0019] The bottom of the fastening nut 5 is fixed with a baffle 15 by bolts. The baffle 15 covers the cutting nozzle 4 to prevent the splashes generated during the cutting process, such as abrasive particles and workpiece debris, from splashing upwards, thereby avoiding safety hazards to the operator.

[0020] The top of the cutting head 3 is sealed with a high-pressure water pipe 16. Water is pumped into the high-pressure water pipe 16 by a high-pressure water pump and then sprayed out from the cutting nozzle 4 for cutting.

[0021] The top of the mounting housing 8 is provided with a through hole 14, through which the high-pressure water pipe 16 passes through the rotating sleeve 9 and the through hole 14.

[0022] A connector 17 is sealed and inserted into one side of the cutting head 3, and an abrasive tube 18 is sealed and inserted into the other end of the connector 17. The abrasive is input into the cutting head 3 through the abrasive tube 18 and then sprayed out from the cutting nozzle 4 along with the water flow to improve the cutting ability.

[0023] Both the outer wall of the abrasive tube 18 and the outer wall of the high-pressure water pipe 16 are fitted with protective sleeves 19. The protective sleeves 19 wrap around the abrasive tube 18 and the high-pressure water pipe 16 to prevent wear and bend.

[0024] A mounting base 20 is welded to one side of the housing 8. The mounting base 20 has two fixing holes. Workers use bolts to pass through the fixing holes to connect the mounting base 20 to the external equipment.

[0025] The working principle of this embodiment is as follows: When in use, the operator uses bolts to pass through the fixing holes to connect the mounting base 20 to the external equipment, then connects one end of the high-pressure water pipe 16 to the outlet end of the high-pressure water pump through the rotary joint, and then connects one end of the abrasive pipe 18 to the external abrasive supply device to complete the installation. During cutting, water is pumped into the high-pressure water pipe 16 by a high-pressure water pump and then sprayed out from the cutting nozzle 4 for cutting. At the same time, abrasive is fed into the cutting head 3 through the abrasive pipe 18 and then sprayed out from the cutting nozzle 4 along with the water flow to improve cutting ability. If the direction needs to be adjusted during the cutting process, the motor 13 is started. Driven by the motor 13, the gear 12 rotates. Then, under the action of the gear 12 meshing with the ring rack 10, the rotating sleeve 9 and the rotating bracket 1 rotate, thereby driving the cutting head 3 and the cutting nozzle 4 to rotate, thus adjusting the cutting direction. Start the electric push rod 7, which causes the mounting plate 2 to rotate, thereby rotating the cutting head 3 and the cutting nozzle 4, and thus adjusting the cutting pitch angle of the cutting nozzle 4.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
