Description

Technical Field

[0001] This invention relates to a deburring device, specifically a valve inner annular groove burr removal device. Background Technology

[0002] In modern industrial production, valves are key components of various fluid control systems, and their performance directly affects the safety, stability, and efficiency of the entire system. The inner annular groove of a valve, as an important channel for fluid flow, plays a decisive role in its normal operation. However, during the valve manufacturing process, due to the inherent characteristics of cutting, casting, and other processes, burrs inevitably form in the inner annular groove. These seemingly insignificant burrs actually have a profound impact on valve performance and product quality.

[0003] Existing deburring equipment mostly uses grinding mechanisms to penetrate deep into the valve to remove burrs. However, valves typically have many grooves, and a single grinding mechanism is inefficient at removing burrs. Although there are also devices that use multiple grinding mechanisms simultaneously, these mechanisms are fixed and generally specialized, only capable of grinding specific valve models. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing burrs from the inner annular groove of a valve, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for removing burrs from the inner annular groove of a valve includes a worktable. A first grinding component and a second grinding component are rotatably connected to the worktable. Both the first grinding component and the second grinding component include a drive shaft, and both drive shafts are drivenly connected to a drive component. The drive shaft of the second grinding component is slidably connected to the worktable.

[0009] As a further embodiment of the present invention: the reversing assembly includes a reversing shaft, which is connected to the drive shaft of the first grinding assembly via gear transmission. Drive pulleys are fixedly connected to the outer sides of both the reversing shaft and the drive shaft of the first grinding assembly. A transmission pulley is rotatably connected to the bottom of the worktable. Transmission belts are respectively sleeved between the transmission pulley and the two drive pulleys. A first tensioning unit for tensioning different transmission belts is also provided at the bottom of the worktable. A driving pulley is fixedly connected to the bottom of the transmission pulley axle, and a driven pulley is fixedly connected to the bottom of the drive shaft of the second grinding assembly.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1: Please refer to Figure 1 and Figure 2 A valve inner annular groove burr removal device, with workbench 1 as the core mounting base, the overall layout and connection relationship of each component are as follows: On the worktable 1, a first grinding assembly 2 and a second grinding assembly 3 are assembled. Both assemblies contain drive shafts as their core components. These two drive shafts are used to drive the grinding parts 8 to grind the inner annular groove of the valve. Both assemblies are driven to rotate by a drive assembly 4 (motor, engine, etc.). The first grinding assembly 2 is directly connected to the output shaft of the motor via a bevel gear set 7. The drive shaft of the second grinding assembly 3 has a dual connection characteristic—it is slidably connected to the worktable 1, and it also transmits power to the motor via a reversing assembly 5. Simultaneously, an adjustment assembly 6 is also provided on the side of the worktable 1. This assembly drives the corresponding drive shaft of the second grinding assembly 3 to move and adjust.

[0028] Example 2: This example discloses a specific implementation method for each component or unit based on the previous example, as follows: Please see Figure 5 , Figure 6 and Figure 7The drive shafts of the first grinding assembly 2 and the second grinding assembly 3 each have a drive end located on the worktable 1. A grinding element 8 is connected to the outer side of the drive end, and the grinding element 8 is fixed to the drive end in a non-rotatable manner. This design ensures stable power transmission to the grinding element 8, and when the drive end rotates, it synchronously drives the grinding element 8 to rotate. The drive end can adopt a regular hexagonal structure, which works in conjunction with the regular hexagonal slot below the grinding element 8 to achieve transmission. Additionally, a blind hole is provided at one end of the drive shaft located at the drive end. A spring 9 is fixedly connected inside the blind hole, while a guide rod 10 is fixedly connected inside the grinding element 8. The guide rod 10 slides into the blind hole, and the lower end of the guide rod 10 abuts against the spring 9. With the elasticity of the spring 9, the grinding element 8 can achieve self-adjustment. The guide rod 10 compresses the spring 9, allowing the grinding part 8 to slide axially relative to the drive end. During grinding, the valve position is repeatedly adjusted, allowing the grinding part 8 to grind different areas and preventing direct rigid contact between the grinding part 8 and the end of the valve's inner annular groove, thus avoiding over-grinding. To prevent the grinding part 8 from getting stuck inside the valve, a connecting rope can be fixed to it, with the other end of the rope fixed to the drive shaft, ensuring that the grinding part 8 can be removed if stuck inside the valve. The grinding part 8 can also be replaced according to the specific grinding requirements of the valve, allowing different grinding intensities to achieve the desired roughness of the valve's inner annular groove.

[0029] Please see Figure 2 , Figure 3 and Figure 4The reversing assembly 5 includes a reversing shaft 11, which is connected to the drive shaft of the first grinding assembly 2 via gears. Based on gear transmission, the reversing shaft 11 and the drive shaft of the first grinding assembly 2 rotate in opposite directions. Drive pulleys 12 are fixedly connected to the outside of both the reversing shaft 11 and the drive shaft of the first grinding assembly 2. The two drive pulleys 12 rotate in opposite directions, and the direction of the drive shaft of the second grinding assembly 3 can be changed by driving the drive shaft of the second grinding assembly 3 through different drive pulleys 12. A transmission pulley 13 is rotatably connected to the bottom of the worktable 1, and transmission belts 14 are respectively sleeved between the transmission pulley 13 and the two drive pulleys 12. To ensure the transmission effect of the transmission belts 14, a first tensioning unit 15 is also provided at the bottom of the worktable 1. The first tensioning unit 15 is used to tension the different transmission belts 14. The first tensioning unit 15 consists of a drive rod 19, which is rotatably connected to the worktable 1. A first tensioning wheel 20 is rotatably connected to the end of the drive rod 19. When the drive rod 19 swings, the first tensioning wheel 20 can make transmission contact with different transmission belts 14, thereby completing the tensioning action of the corresponding transmission belt 14. The grinding direction can be switched by manually changing the position of the first tensioning wheel 20. Corresponding limiting clamps can also be set on both sides of the drive rod 19. After the drive rod 19 tensions the corresponding transmission belt 14, the position of the drive rod 19 can be limited by the limiting clamps, eliminating the need for continuous manual operation of the drive rod 8 by the processing personnel.

[0030] In addition, a drive pulley 16 is fixedly connected to the bottom of the axle of the transmission pulley 13, and a driven pulley 17 is fixedly connected to the bottom of the drive shaft of the second grinding assembly 3. The drive pulley 16 and the driven pulley 17 are connected by a linkage belt 18 to achieve the transmission of power from the reversing assembly 5 to the second grinding assembly 3. Considering the transmission stability of the linkage belt 18, a second tensioning unit 21 is also provided at the bottom of the worktable 1. This second tensioning unit 21 includes an adaptive telescopic rod 22 and a second tensioning wheel 23, wherein the second tensioning wheel 23 is rotatably connected to the telescopic end of the adaptive telescopic rod 22. Under the telescopic drive of the adaptive telescopic rod 22, the second tensioning wheel 23 can automatically adjust the tension of the linkage belt 18. It should be noted that this application uses belt drive to prevent the device from transmitting excessive torque, which is sufficient to meet the valve processing requirements during polishing and grinding. When the internal roughness of the valve is too large, a sprocket drive can be used to provide sufficient torque.

[0031] To meet the sliding installation requirements of the drive shaft of the second grinding component 3, a through groove 24 is provided on the worktable 1. A slider 25 is slidably connected within the through groove 24, and the drive shaft of the second grinding component 3 is rotatably connected to the slider 25. When the slider 25 slides within the through groove 24, it can drive the drive shaft of the second grinding component 3 to move synchronously. The drive shaft of the second grinding component 3 can also be slidably connected to the worktable 1 using other connection methods. For example, two limiting rings can be fixed on the drive shaft of the second grinding component 3, with the limiting rings located above and below the table surface of the worktable 1, thereby limiting the longitudinal movement of the drive shaft. During the sliding process, it can also rotate to achieve grinding.

[0032] The core component of the adjusting assembly 6 is the screw 26, which is threadedly connected to the worktable 1. One end of the screw 26 is rotatably connected to the slider 25, while the other end is fixedly connected to a handwheel 27. The axis of the screw 26 is parallel to the sliding direction of the slider 25. In use, rotating the handwheel 27 drives the screw 26 to rotate, which in turn causes the slider 25 to slide along the through groove 24, ultimately adjusting the position of the drive shaft of the second grinding assembly 3. Alternatively, an electric telescopic rod can be used to electrically drive the slider 25.

[0033] This application uses a motor-driven grinding system. Although the direction of the first grinding component 2 and the second grinding component 3 can be adjusted by changing the direction of the motor, without the reversing component 5, the direction switching of the two grinding components must be performed simultaneously. This makes it difficult to switch the grinding direction of only one grinding component during valve grinding. In this application, when only the grinding direction of the first grinding component 2 needs to be changed, the direction of the first grinding component 2 can be changed by switching the motor direction in conjunction with the reversing component 5. When only the grinding direction of the second grinding component 3 needs to be changed, it can be achieved solely through the reversing component 5.

[0034] Working principle: The first grinding component 2 and the second grinding component 3 mounted on the worktable 1 are both powered by the drive component 4, driving the grinding part 8 to rotate and grind. The first grinding component 2 is directly connected to the motor output shaft via the bevel gear set 7; the drive shaft of the second grinding component 3 is slidably connected to the through groove 24 of the worktable 1 via the slider 25, and the power is transmitted through the reversing component 5, and the position can be adjusted by the adjusting component 6.

[0035] The grinding part 8 and the drive end adopt a fixed structure that cannot be rotated relative to each other (such as a regular hexagonal structure and slot fit). With the elastic adaptation design of the guide rod 10 and the spring 9 in the blind hole of the drive shaft, it can not only stably transmit power, but also realize axial adaptive adjustment, avoid rigid contact and excessive grinding. The connecting rope on the grinding part 8 can prevent it from getting stuck.

[0036] The reversing component 5, by cooperating with different transmission belts 14, allows the rotation direction of the transmission pulley 13 to be adjusted as needed, and then switches the direction of the second grinding component 3 via the drive pulley 12 and the transmission belt 14. The adjusting component 6 drives the screw 26 by rotating the handwheel 27, which in turn moves the slider 25 and the drive shaft of the second grinding component 3 along the through groove 24, achieving precise adjustment of the grinding position. The two components work together to meet the requirements of efficient and precise burr removal.

[0037] When using it, first adjust the position of the second grinding component 3 according to the valve hole position, then select the appropriate grinding part 8, and after the grinding part 8 is installed, put the valve hole positions on the outside of different grinding components to achieve deburring.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
