Description

Technical Field

[0001] This application relates to the field of valve body processing technology, specifically to a hole-expanding device for valve body processing. Background Technology

[0002] In the field of valve manufacturing, the valve body, as the core component of fluid control, has its internal channels whose machining accuracy directly affects sealing performance and service life.

[0003] Among them, hole reaming is one of the key processes in machining. Its processing quality directly affects the sealing performance and service life of the valve body. Traditional hole reaming devices usually adopt a single drilling structure, which uses a motor to drive the reamer to rotate and cooperates with a cylinder to feed to achieve hole diameter processing.

[0004] For example, patent CN219025999U discloses a precision reaming device for processing forged valve bodies. This patent uses a first motor to drive a bidirectional threaded rod to rotate, which in turn moves the clamping blocks on both sides toward each other to achieve horizontal clamping and fixing of the valve body. During reaming, the lifting component adjusts the height of the reaming motor and the drill bit, and the rotating motor drives the reaming component to rotate to adapt to the requirements of annular multi-hole processing.

[0005] However, during the reaming operation, the drill bit will generate a large amount of metal chips when cutting the valve body's inner bore. Since the valve body is usually a closed or semi-closed structure, these chips are prone to settling and accumulating at the bottom of the channel or in the blind area of ​​the stepped structure under the action of gravity, forming residual pollution. Especially when machining valve bodies with a large depth-to-diameter ratio, the chips will be affected by the adhesion of coolant and the micro-valve structure of the bore wall, and will embed into the inner wall surface, thus causing scratches on the valve body or sealing failure.

[0006] Therefore, it is necessary to provide a reaming device for valve body machining to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] like Figures 1-2As shown, this application provides a reaming device for valve body processing, which is suitable for the machining station of valve manufacturing production line and is mainly used for reaming operations. Specifically, the reaming device for valve body processing includes a base 1 and a reaming mechanism 2 fixedly installed on the upper end of the base 1. The reaming mechanism 2 includes a bracket 20 fixedly installed on the upper surface of the base 1.

[0037] To perform the hole enlargement process, a fixed plate 21 is fixedly installed at the middle of the top of the bracket 20. A slide rod 27 is slidably installed on the fixed plate 21. A mounting plate 23 is fixedly connected to the bottom of the slide rod 27. A first cylinder 22 is installed at the center of the fixed plate 21. The output end of the first cylinder 22 is fixedly connected to the top surface of the mounting plate 23. Thus, when the first cylinder 22 is started, the mounting plate 23 can be driven to rise and fall stably along the axial direction of the slide rod 27.

[0038] Meanwhile, a dual-axis cylinder 24 is installed in the center of the bottom surface of the mounting plate 23. A clamping plate 25 is fixedly installed at the output end of the dual-axis cylinder 24. The inner working surface of the clamping plate 25 is provided with anti-slip texture, so that the horizontal clamping and positioning operation of the valve body can be achieved by the synchronous contraction of the dual-axis cylinder 24.

[0039] Furthermore, a frame 26 is fixedly installed on the upper surface of the base 1 directly below the clamping plate 25. The first motor 29 is installed inside the frame 26, and the output shaft of the first motor 29 vertically extends through the top plate of the frame 26 and is fixedly connected to a reaming drill 28.

[0040] It should be noted that the reamer 28 and the clamping center of the clamping plate 25 are set coaxially. During processing, the clamping plate 25 is first driven by the dual-axis cylinder 24 to clamp the valve body. Then, the first cylinder 22 pushes the mounting plate 23 down to move the valve body closer to the reamer 28. Finally, the first motor 29 is started to drive the reamer 28 to rotate and complete the reaming.

[0041] In order to clean the inside of the valve body holes, such as Figures 1-6 As shown, a cleaning mechanism 3 is provided in the middle of the support 20. The cleaning mechanism 3 includes a crossbeam 30 fixedly installed in the middle of the support 20. The crossbeam 30 is located between the reamer 28 and the top of the support 20. At the same time, a fixing frame 31 is fixedly installed in the middle of the top surface of the crossbeam 30. Two sets of slide rails 32 are installed on the upper end of the fixing frame 31, and a slider 33 is slidably installed on the upper end of the slide rails 32.

[0042] Meanwhile, a receiving plate 34 is fixedly arranged between the sliders 33, and a second cylinder 35 is installed in the inner cavity of the fixed frame 31. The output end of the second cylinder 35 is fixedly connected to the receiving plate 34, so that when the second cylinder 35 is started, it can push the receiving plate 34 to move horizontally back and forth along the slide rail 32.

[0043] Furthermore, a temporary storage box 37 is fixedly installed on one side of the front end of the receiving plate 34. The side wall of the temporary storage box 37 is provided with an air inlet (not shown in the figure), which is connected to an external air pump through a hose.

[0044] Meanwhile, a second motor 36 is installed on the other side of the receiving plate 34. The output shaft of the second motor 36 passes through the receiving plate 34 and extends into the inner cavity of the temporary storage box 37. A hollow shaft 38 with a cavity is fixedly connected to the end of the output shaft. The hollow shaft 38 also extends outward through the front wall of the temporary storage box 37.

[0045] Furthermore, the section of the hollow shaft 38 located inside the temporary storage box 37 has a through hole (not shown in the figure), which allows the inner cavity of the temporary storage box 37 to communicate with the inner cavity of the hollow shaft 38. At the same time, multiple sets of oblique nozzles 39 are evenly distributed around the exposed section of the hollow shaft 38. The nozzles are tilted outward to facilitate the subsequent cleaning of debris inside the valve body.

[0046] Meanwhile, an annular sponge ring 40 is fitted onto the top of the hollow shaft 38. The outer diameter of the sponge ring 40 is slightly larger than the valve body orifice diameter and has elastic compression characteristics.

[0047] When cleaning is required, the first cylinder 22 can be started to lift the valve body with the enlarged hole to the top height of the bracket 20. Then the second cylinder 35 is started to push the receiving plate 34 forward until the hollow shaft 38 moves directly below the valve body hole. At this time, the first cylinder 22 drives the valve body to move slowly downward. After the sponge ring 40 is deformed by pressure, it fits tightly against the hole wall. At the same time, the hollow shaft 38 goes deep into the hole.

[0048] Subsequently, the external air pump injects high-pressure gas into the temporary storage box 37. The airflow enters the inner cavity through the through hole of the hollow shaft 38 and is sprayed out from the nozzle 39 in a scattering manner, impacting the hole wall and adhering debris. Simultaneously, the second motor 36 is started to drive the hollow shaft 38 to rotate, so that the airflow coverage area of ​​the nozzle 39 covers the entire hole wall as it rotates.

[0049] At this point, the detached debris is pushed downwards by the airflow, and the sponge ring 40 forms a physical barrier to prevent the debris from overflowing. Finally, the debris falls onto the surface of the receiving plate 34 for subsequent centralized processing.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
