Description

Technical Field

[0001] This utility model relates to the field of flange nut processing technology, and in particular to a processing equipment for producing hexagonal flange nut assemblies. Background Technology

[0002] Hexagonal flange nut assemblies are widely used standard parts in the mechanical field. As key mechanical connection components, they are usually composed of two parts: a hexagonal nut and a flange. The hexagonal nut is the core of the operation. Its unique hexagonal shape is compatible with the operation of tools such as wrenches and sockets, greatly facilitating manual or mechanical tightening and disassembly, ensuring the convenience of connection and separation. The precisely machined threads inside the nut strictly follow specific specifications and standards, perfectly matching the corresponding bolts. The tightening force is generated through the engagement of the threads, achieving a stable connection between components.

[0003] However, existing processing equipment for producing hexagonal flange nut assemblies often uses simple clamps for fixing, which makes it difficult to ensure that the nut is always in the center position during the tapping process. This can easily lead to deviation, which not only greatly reduces the accuracy of tapping and makes the thread quality inconsistent, but may also damage the tap, increase production costs and processing time. In addition, when tapping, the tap rotates at high speed and comes into contact with the nut, which can generate safety hazards such as flying debris, posing a threat to the personal safety of operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a processing equipment for the production of hexagonal flange nut assemblies. It solves the problem that existing processing equipment for hexagonal flange nut assemblies often uses simple clamps for fixing, making it difficult to ensure the nut remains centered during tapping. This leads to easy misalignment, significantly reducing tapping accuracy and resulting in inconsistent thread quality. It can also damage the tap, increasing production costs and processing time. Furthermore, during tapping, the high-speed rotation of the tap and its contact with the nut can generate flying debris and other safety hazards, threatening the personal safety of operators.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A processing device for producing hexagonal flange nut assemblies includes a base, a U-shaped frame fixedly mounted on the upper end of the base, cross grooves formed on both side walls of the U-shaped frame, a hydraulic cylinder fixedly mounted on the upper end of the U-shaped frame, an electric telescopic rod mounted on the output end of the hydraulic cylinder, a fixed seat fixedly mounted on the lower end of the electric telescopic rod, symmetrical sliding grooves formed on the fixed seat, side rods fixedly mounted on both side walls of the fixed seat, two side rods slidably mounted in two cross grooves respectively, a mounting frame fixedly mounted on the lower end of the fixed seat, a drive motor fixedly mounted inside the mounting frame, and a tap mounted on the output end of the drive motor;

[0023] This application provides a processing equipment for producing hexagonal flange nut assemblies. It effectively solves the problem that existing processing equipment for hexagonal flange nut assemblies often uses simple clamps for fixing, making it difficult to ensure the nut remains centered during tapping. This leads to easy displacement, significantly reducing tapping accuracy and resulting in inconsistent thread quality. It can also damage the tap, increasing production costs and processing time. Furthermore, during tapping, the high-speed rotation of the tap and its contact with the nut can generate flying debris and other safety hazards, threatening the safety of operators. This new equipment first places the hexagonal flange nut in a specific position, allowing it to compress relevant components and then reset. Then, another component is rotated to apply pressure. Multiple components slide inward to fix the nut's sidewall, increasing tapping stability and ensuring the nut remains centered throughout the process. This greatly improves tapping accuracy and effectiveness. During tapping, the relevant device is activated to move and rotate the components. At the start of tapping, the contact force on a specific component triggers a series of component movements, compressing the first spring. Throughout the process, this component is effectively protected, significantly improving protection and operational safety. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that existing processing equipment for producing hexagonal flange nut assemblies often uses simple clamps for fixing, which makes it difficult to ensure that the nut is always in the center position during tapping, and it is easy to deviate. This not only greatly reduces the accuracy of tapping and makes the thread quality inconsistent, but also may cause damage to the tap, increase production costs and processing time. Moreover, during tapping, the tap rotates at high speed and comes into contact with the nut, which will generate safety hazards such as flying debris, threatening the personal safety of operators. The overall idea is as follows: A processing equipment for producing hexagonal flange nut assemblies includes a base 11, a U-shaped frame 12 is fixedly installed on the upper end of the base 11, and cross grooves 13 are opened on both side walls of the U-shaped frame 12. A hydraulic cylinder 14 is fixedly installed. An electric telescopic rod is installed on the output end of the hydraulic cylinder 14. A fixed seat 15 is fixedly installed at the lower end of the electric telescopic rod. The fixed seat 15 has symmetrically opened sliding grooves 16. Side rods 17 are fixedly installed on both side walls of the fixed seat 15. The two side rods 17 are slidably installed in two cross grooves 13 respectively. A mounting bracket 18 is fixedly installed at the lower end of the fixed seat 15. A drive motor 19 is fixedly installed inside the mounting bracket 18. A tap 21 is installed on the output end of the drive motor 19. When tapping, the hydraulic cylinder 14 can be activated. Under the action of the hydraulic cylinder 14, the fixed seat 15 and the side rods 17 will move downward. At this time, the drive motor 19 is activated, which will drive the tap 21 to rotate. When the tap 21 moves downward, it will tap the hexagonal flange nut.

[0025] A protective mechanism is provided below the fixed base 15;

[0026] The protective mechanism includes a protective cover 22. Two slides 23 are symmetrically fixedly installed on the upper end of the protective cover 22. The two slides 23 are slidably installed in two slide grooves 16. Side blocks 24 are fixedly installed on both side walls of the protective cover 22. Slide columns 25 are fixedly installed on the upper ends of the two side blocks 24. A first spring 26 is sleeved on each of the two slide columns 25. The two ends of the two first springs 26 are fixedly connected to the two side blocks 24 and the two side rods 17, respectively. When tapping begins, the protective cover 22 will first contact the placement frame 31. The force applied to the protective cover 22 will cause the slides 23 to slide upwards within the slide grooves 16. At this time, the protective cover 22 will move the side blocks 24, and the side blocks 24 will move the slide columns 25 within the side rods 17. The first springs 26 will then be compressed, ensuring that the protective cover 22 provides protection throughout the entire tapping process, significantly improving the protective effect and safety.

[0027] A placement rack 31 is fixedly installed on the upper end of the base 11. The placement rack 31 is located inside the U-shaped frame 12 and is kept horizontal with it. The upper end of the placement rack 31 has a circular groove 32 and an inner groove 33. The circular groove 32 is located around the inner groove 33. Multiple sliding frames 34 are evenly and equidistantly slidably installed on the circumferential surface of the inner groove 33. A wedge block 35 is fixedly installed on the opposite end of each sliding frame 34. A second spring 36 is fixedly installed on each sliding frame 34. Both ends of each second spring 36 are fixedly connected to the wedge block 35 and the inner wall of the inner groove 33. A threaded ring 37 is threaded in the inner wall of the inner groove 33. When using, the hexagonal method can be first installed. When the hexagonal flange nut is placed in the inner groove 33, it will press the wedge block 35, causing the wedge block 35 to slide outward and drive the second spring 36 to compress. After the hexagonal flange nut is placed, the second spring 36 will drive the wedge block 35 to reset. Then, the threaded ring 37 can be rotated inside the inner groove 33. The threaded ring 37 is located above the wedge block 35 and will move downward under the rotation of the threaded ring 37. At this time, the threaded ring 37 will apply a compressive force to the wedge block 35. Under the action of this compressive force, the wedge block 35 will slide inward. At this time, multiple wedge blocks 35 will fix the side wall of the hexagonal flange nut, increasing its tapping stability.

[0028] By fixing the hexagonal flange nut in the center with multiple wedge blocks 35, the nut can always be kept in the center position when placed, which is not easy to shift and enhances the accuracy and effect of tapping.

[0029] To address the problems existing in the prior art, this utility model provides a processing equipment for producing hexagonal flange nut assemblies. First, the hexagonal flange nut is placed in a specific position, causing it to press against relevant components and then reset. Then, another component is rotated to apply pressure. Multiple components slide inward to fix the nut's sidewall, increasing tapping stability and ensuring the nut remains centered throughout the process, significantly improving tapping accuracy and effectiveness. During tapping, a related device is activated to move and rotate components for the tapping operation. At the start of tapping, a specific component, upon contact and under force, triggers a series of component movements, compressing the first spring. Throughout the process, this component is effectively protected, significantly improving protection and operational safety.

[0030] Working principle:

[0031] The first step is to place the hexagonal flange nut in the inner groove 33. At this time, the hexagonal flange nut will press the wedge block 35, causing the wedge block 35 to slide outward and drive the second spring 36 to compress. After the hexagonal flange nut is placed, the second spring 36 will drive the wedge block 35 to return to its original position. Then, the threaded ring 37 can be rotated inside the inner groove 33. Under the rotation of the threaded ring 37, it will move downward. At this time, the threaded ring 37 will apply a squeezing force to the wedge block 35. Under the action of this squeezing force, the wedge block 35 will slide inward. At this time, multiple wedge blocks 35 will fix the side wall of the hexagonal flange nut, increasing its tapping stability. Moreover, by fixing multiple wedge blocks 35 towards the center, the hexagonal flange nut can always be kept in the center position when placed, which is not easy to deviate, thus enhancing the tapping accuracy and effect.

[0032] In the second step, the hydraulic cylinder 14 can be activated during tapping. Under the action of the hydraulic cylinder 14, the fixed seat 15 and the side rod 17 will move downward. At this time, the drive motor 19 will be activated, which will drive the tap 21 to rotate. When the tap 21 moves downward, it will tap the hexagonal flange nut. When tapping begins, the protective cover 22 will first contact the placement frame 31. The protective cover 22 will be subjected to force, which will drive the slide 23 to slide upward in the slide groove 16. At this time, the protective cover 22 will drive the side block 24 to move. The side block 24 will drive the slide column 25 to slide inside the side rod 17. At this time, the first spring 26 will be compressed, so that the protective cover 22 can provide protection throughout the tapping process, and the protection effect and safety are greatly improved.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
