Description

Technical Field

[0001] This utility model relates to the field of waterjet processing technology, and in particular to a waterjet deflection mechanism. Background Technology

[0002] Waterjet cutting, also known as high-pressure water jet cutting technology, is a technique that uses a high-pressure pump to pressurize ordinary water to hundreds of megapascals or even higher pressures, and then sprays it out as a high-speed jet through a specially designed fine nozzle. The kinetic energy of the high-speed jet is used to cut various materials such as metal, stone, glass, and ceramics. Compared with traditional cutting methods, waterjet cutting has significant advantages such as no thermal deformation, smooth cuts, no dust pollution, and a wide range of materials that can be cut. It is widely used in fields such as machinery manufacturing, building decoration, and aerospace. In the process of waterjet cutting, in order to cut complex-shaped workpieces or adjust the jet cutting angle to adapt to different processing needs, a jet deflection mechanism is required. The jet deflection mechanism is a core mechanical structure installed between the waterjet nozzle and the high-pressure pipeline to change the direction of the high-pressure water jet. By adjusting the deflection angle, the waterjet jet can be precisely applied to the target cutting position of the workpiece, improving cutting flexibility and processing accuracy.

[0003] The existing water jet deflection mechanism has the following shortcomings: The existing water jet deflection mechanism can only control the angle adjustment of the jet in a single direction, and cannot achieve synchronous or independent adjustment in the horizontal and vertical directions, which makes it difficult to meet the multi-dimensional cutting requirements of complex curved workpieces. At the same time, the existing device uses a fixed bolt or welding installation structure for the water jet nozzle, which requires special tools and is complicated to disassemble and assemble. This results in low replacement efficiency after the nozzle wears out, which affects the processing progress. Utility Model Content

[0006] The horizontal deflection assembly includes an annular support plate, which is fixedly connected to the bottom end of a fixed column.

The end of the connecting column away from the driven wheel extends through to the outside of the vertical support plate and is fixedly connected to the connecting plate.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figure 1 - Figure 4This utility model provides a technical solution: a water jet deflection mechanism, comprising two fixed columns 1, a horizontal deflection component 2 fixedly connected to the bottom of the two fixed columns 1, vertical deflection components 3 arranged on both the left and right sides of the inner side of the horizontal deflection component 2, a rotating bracket 4 arranged at the bottom of the opposite side of the two vertical deflection components 3, a water jet nozzle 5 arranged in the middle of the rotating bracket 4, and a water delivery hose 6 fixedly connected to the top of the water jet nozzle 5. The horizontal deflection component 2 includes an annular support plate 21, which is fixedly connected to the bottom end of the fixed columns 1. A movable groove 1 is opened in the middle of the assembly. The left and right sides of the movable groove 1 are rotatably connected to the drive wheel 23. The outer surfaces of the two drive wheels 23 are meshed with a driven gear ring 24. The driven gear ring 24 is rotatably connected to the inner side of the annular support plate 21. The vertical deflection assembly 3 includes a vertical support plate 31. The two vertical support plates 31 are respectively fixedly connected to the left and right sides of the inner wall of the driven gear ring 24. A movable groove 2 is opened inside the vertical support plate 31. The upper part of the movable groove 2 is rotatably connected to the drive wheel 33. The bottom of the outer surface of the drive wheel 33 is meshed with the driven wheel 34.

[0019] like Figure 2 and Figure 3 As shown, horizontal adjustment motors 22 are fixedly connected to the top left and right sides of the annular support plate 21. The output shaft of the horizontal adjustment motor 22 passes through the interior of the movable groove 1 and is fixedly connected to the middle of the drive wheel 23. Vertical adjustment motors 32 are fixedly connected to the opposite surfaces of the two vertical support plates 31. The output shaft of the vertical adjustment motor 32 passes through the interior of the movable groove 2 and is fixedly connected to the middle of the drive wheel 33. Here, the horizontal adjustment motor 22 and the vertical adjustment motor 32 provide stable power to the drive wheel 23 and the drive wheel 33 respectively, ensuring that the drive wheel can accurately drive the subsequent components, thereby ensuring the accuracy of the water jet nozzle 5 angle adjustment and avoiding adjustment deviation due to insufficient or unstable power.

[0020] like Figure 4 As shown, the rotating bracket 4 includes a connecting column 41, which is fixedly connected to the side of the driven wheel 34 near the water jet nozzle 5. The end of the connecting column 41 away from the driven wheel 34 extends through to the outside of the vertical support plate 31 and is fixedly connected to the connecting plate 42. A limiting slide rod 43 is fixedly connected to both the front and rear sides of the two connecting plates 42. Here, the connecting column 41 plays the role of transmitting the rotational power of the driven wheel 34, which can convert the rotation of the driven wheel 34 into the vertical rotation of the connecting plate 42. The limiting slide rod 43 provides a stable sliding track for the arc-shaped clamping plate 44, preventing the arc-shaped clamping plate 44 from deviating during movement and ensuring the clamping accuracy of the water jet nozzle 5.

[0021] like Figure 4As shown, an arc-shaped clamping plate 44 is slidably connected to the left and right sides of the outer surface of the two limiting slide rods 43. An annular groove 51 is opened on the outer surface of the water jet nozzle 5. The two arc-shaped clamping plates 44 are respectively slidably clamped to the left and right sides of the inner surface of the annular groove 51. Here, the arc-shaped structure of the arc-shaped clamping plate 44 has a higher degree of fit with the outer surface of the water jet nozzle 5. Together with the annular groove 51, it can achieve a firm clamping of the water jet nozzle 5, preventing the water jet nozzle 5 from shaking or displacing due to the impact of high-pressure water flow during operation. At the same time, the clamping structure also facilitates quick assembly and disassembly.

[0022] like Figure 4 As shown, threaded sleeves 45 are fixedly connected to the opposite sides of the two arc-shaped clamping plates 44. The inner surface of the threaded sleeve 45 away from the arc-shaped clamping plate 44 is threadedly connected to the transmission screw 46. Here, the threaded engagement between the threaded sleeve 45 and the transmission screw 46 can convert the rotational motion of the transmission screw 46 into the linear motion of the threaded sleeve 45, thereby driving the arc-shaped clamping plate 44 to move along the limiting slide bar 43. The threaded transmission has the characteristics of high transmission accuracy and good self-locking, which can ensure that the arc-shaped clamping plate 44 moves in a precise position and is not easy to loosen after clamping.

[0023] like Figure 4 As shown, a movable groove 3 is provided in the middle of the connecting plate 42, running vertically through it. The end of the transmission screw 46 away from the threaded sleeve 45 passes through the interior of the movable groove 3 and is fixedly connected to the knob 47. Here, the knob 47 is set so that the operator can manually rotate it to drive the transmission screw 46, improving the ease of operation.

[0024] The usage and working principle of this device are as follows: When using this water jet deflection mechanism, first adjust the angle of the water jet nozzle 5 according to the processing requirements. When horizontal angle adjustment is required, start the horizontal adjustment motor 22 on the annular support plate 21. The output shaft of the horizontal adjustment motor 22 drives the drive wheel 23 to rotate in the movable groove. Since the drive wheel 23 meshes with the driven gear ring 24, the drive wheel 23 will drive the driven gear ring 24 to rotate inside the annular support plate 21. When the driven gear ring 24 rotates, it will drive the fixed connection with it. The vertical support plate 31 rotates horizontally in sync with the vertical support plate 31, which in turn drives the vertical deflection assembly 3, the rotating bracket 4, and the water jet nozzle 5 to rotate horizontally together until the water jet nozzle 5 reaches the required horizontal angle, at which point the horizontal adjustment motor 22 is turned off. When vertical angle adjustment is required, the vertical adjustment motor 32 on the vertical support plate 31 is started. The output shaft of the vertical adjustment motor 32 drives the second driving wheel 33 to rotate in the second movable groove. The second driving wheel 33 drives the driven wheel 34 to rotate through meshing. When the driven wheel 34 rotates, it is connected to the connecting column 41. The connecting plate 42 and the entire rotating bracket 4 rotate vertically around the axis of the driven wheel 34. The rotating bracket 4 then drives the water jet nozzle 5 to rotate vertically. Once the water jet nozzle 5 reaches the required vertical angle, the vertical adjustment motor 32 is turned off. When the water jet nozzle 5 needs to be replaced, the operator manually rotates the knob 47 in the opposite direction. The knob 47 drives the transmission screw 46 to rotate. The transmission screw 46 drives the threaded sleeve 45 to move away from the water jet nozzle 5 through threaded engagement. The threaded sleeve 45 drives the arc-shaped clamp 44 to slide along the limiting slide bar 43, making... The arc-shaped clamp 44 disengages from the annular groove 51 on the outer surface of the waterjet nozzle 5, at which point the old waterjet nozzle 5 can be removed. The new waterjet nozzle 5 is placed between the two arc-shaped clamps 44, and the knob 47 is rotated clockwise. The transmission screw 46 drives the threaded sleeve 45 and the arc-shaped clamp 44 to move closer to the waterjet nozzle 5 until the arc-shaped clamp 44 is engaged in the annular groove 51, thus fixing the waterjet nozzle 5. Throughout the entire operation, the water supply hose 6 continuously delivers high-pressure water to the waterjet nozzle 5 to ensure the normal operation of the waterjet cutting.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
