Description

Technical Field

[0001] This application relates to the field of valve component processing technology, and in particular to a multi-station valve component processing machine tool. Background Technology

[0002] The valve body, a component of valve assembly, is typically formed using a casting process. After casting, the valve body usually requires precision machining processes such as milling, drilling, and grinding to meet the requirements of complex structures. (Refer to...) Figure 1 In related technologies, the valve body after casting mainly includes three fluid channels 29. The three fluid channels 29 intersect and connect at the same position. Two of the fluid channels 29 have parallel axial directions and are perpendicular to the axial direction of the remaining fluid channel 29. To facilitate the assembly of the valve body with other components, each fluid channel 29 is provided with a boss 30 at its end. The boss 30 can be designed as a circle, an ellipse, or a square with rounded corners as needed.

[0003] Since the milling, drilling and grinding processes of the valve body involve the end faces of the bosses 30 of multiple fluid channels 29, the clamping fixtures on traditional machine tools usually need to frequently disassemble and reassemble the valve body to change the processing position, resulting in low processing efficiency. Summary of the Invention

[0004] To facilitate changing the processing location of valve components as needed, and to avoid frequent disassembly and assembly of valve components, thereby improving processing efficiency, this application provides a multi-station valve component processing machine tool.

[0005] The multi-station valve component processing machine tool provided in this application adopts the following technical solution: A multi-station valve component processing machine tool, comprising a machine tool body, and further comprising: A tooling holder, which is rotatably mounted on the machine tool body; A fixed clamping seat is rotatably mounted on a tooling seat, and the rotation axis of the fixed clamping seat is perpendicular to the rotation axis of the tooling seat. A movable seat is slidably mounted on a tooling seat, and the moving direction of the movable seat is parallel to the rotation axis of the fixed clamping seat. A movable clamping seat is rotatably mounted on a movable seat, and the rotation axis of the movable clamping seat is parallel to the rotation axis of the fixed clamping seat. The movable clamping seat is used to cooperate with the fixed clamping seat to clamp and fix the valve component. The first rotational drive component is used to drive the tooling base to rotate. The second rotation drive is used to drive the fixed clamping seat to rotate. A moving drive is used to drive the moving seat to move toward or away from the fixed clamping seat; The third rotation drive is used to drive the moving clamp to rotate.

[0006] Preferably, the rotation axis of the tooling base is arranged in the horizontal direction, and a machining groove is provided on the tooling base. The machining groove extends through the opposite sides of the tooling base, and the fixed clamping base, the movable base and the movable clamping base are all located in the machining groove. The extension direction of the machining groove is perpendicular to the rotation axis of the fixed clamping base.

[0007] Preferably, the fixed clamping seat and the movable clamping seat are provided with a first clamping body, a second clamping body and a third clamping body on their respective sides that are close to each other. The first clamping body, the second clamping body and the third clamping body on the fixed clamping seat and the movable clamping seat correspond to three fluid channels respectively. Two of the first clamping bodies, two of the second clamping bodies and two of the third clamping bodies are used to clamp and fix the end bosses of the corresponding fluid channels.

[0008] Preferably, each of the two first clamping bodies has a first contact surface on its adjacent side, which is used to contact the outer wall of the corresponding fluid channel end boss. Each of the two second clamping bodies has a second contact surface on its adjacent side, which is used to contact the outer wall of the corresponding fluid channel end boss. The plane of the second clamping body is parallel to the plane of the first clamping body. Each of the two third clamping bodies has a third contact surface on its adjacent side, which is used to contact the outer wall of the corresponding fluid channel end boss. The plane of the third clamping body is perpendicular to the plane of the second clamping body.

[0009] Preferably, a notch is provided through the first, second, and third mating surfaces, and the extension direction of the notch is perpendicular to the plane where the corresponding first, second, or third clamping body is located.

[0010] Preferably, the fixed clamping seat and the movable clamping seat are provided with limiting bodies, the limiting bodies are located between the first clamping body and the second clamping body, the distance between the two limiting bodies on the fixed clamping seat and the movable clamping seat is less than the distance between the two first contact surfaces on the same side, and the side of the limiting body near the first contact surface is used to abut against the surface of the fluid channel end boss corresponding to the first contact surface.

[0011] Preferably, both the second clamping body and the third clamping body are detachably mounted on the corresponding fixed clamping seat or movable clamping seat by bolts.

[0012] Preferably, the first clamping body, the second clamping body, and the third clamping body are all provided with mounting grooves, and a slider is slidably disposed in the mounting groove. The sliding direction of the slider is parallel to the rotation axis of the fixed clamping seat. A limiting plate is provided on the slider. The limiting plate is used to abut against the end face of the fluid channel end boss at the corresponding position. An adjustment component is provided in the mounting groove for adjusting the sliding of the slider so that the limiting plate extends or retracts to the corresponding first clamping body, second clamping body, or third clamping body.

The weight of the counterweight is greater than the elastic force of the elastic reset member.

[0014] Preferably, the elastic reset member includes a spring for driving the slider to move the limiting plate away from the valve component. One end of the spring is disposed on the slider and the other end is disposed on the inner wall of the mounting groove.

[0015] In summary, this application includes the following beneficial technical effects: Before clamping the valve component, the movable clamping seat and the fixed clamping seat are in a far apart state, providing sufficient space for the valve component to be placed. During machining, the valve component is placed between the fixed clamping seat and the movable clamping seat, so that the valve component is in contact with the desired position of the fixed clamping seat. Then, the movable clamping seat and the movable seat are moved towards the fixed clamping seat by the driving component, so that the movable clamping seat and the fixed clamping seat clamp and fix the valve component. Then, the valve component is finished by the tool on the machine tool body. During the machining process, the tooling seat is rotated by the first rotary driving component as needed to move different parts of the valve component to the machining position, or the fixed clamping seat and the movable clamping seat are rotated by the second rotary driving component and the third rotary driving component at the same time, so that the valve component is rotated. With the rotation capability of the CNC tool head on the machine tool body, the valve component can be changed to change the machining position as needed, which helps to achieve a variety of finishing operations without frequent disassembly and assembly of the valve component or frequent changes of work position, which helps to improve machining efficiency.

[0025] The following combination Figures 2-8 This application will be described in further detail.

[0026] Example 1:

[0027] This application discloses a multi-station valve component processing machine tool. (Refer to...) Figure 2 and Figure 3The multi-station valve component processing machine tool includes a machine tool body 1, a tooling base 2, a fixed clamping base 3, a movable base 4, a movable clamping base 5, a first rotary drive component 6, a second rotary drive component, a movable drive component, and a third rotary drive component. The tooling base 2 is rotatably mounted on the machine tool body 1 to drive the valve component to switch processing positions. Specifically, the rotation axis of the tooling base 2 is set in the horizontal direction, so that different surfaces can be adjusted to face upward or horizontally, or the processing surface can be rotated to the required tilt angle to meet different processing requirements. A processing groove 9 is opened at the end face of the tooling base 2, and the processing groove 9 passes through the opposite sides of the tooling base 2.

[0028] Reference Figure 2 and Figure 3 The fixed clamping seat 3 is rotatably mounted on the inner wall of the machining slot 9 of the tooling seat 2. The rotation axis of the fixed clamping seat 3 is perpendicular to the rotation axis of the tooling seat 2. Furthermore, the extension direction of the machining slot 9 is perpendicular to the rotation axis of the fixed clamping seat 3. The movable seat 4 is slidably mounted on the inner wall of the machining slot 9 away from the fixed clamping seat 3. The moving direction of the movable seat 4 is parallel to the rotation axis of the fixed clamping seat 3. The movable clamping seat 5 is rotatably mounted on the side of the movable seat 4 close to the fixed clamping seat 3. The movable clamping seat 5 is aligned with the fixed clamping seat 3. The rotation axis of the movable clamping seat 5 is parallel to the rotation axis of the fixed clamping seat 3. The movable clamping seat 5 is used to cooperate with the fixed clamping seat 3 to clamp and fix the valve component.

[0029] Reference Figure 2 and Figure 3 The first rotation drive 6 is mounted on the machine tool body 1 and is used to drive the tooling seat 2 to rotate; the second rotation drive 6 is mounted on the tooling seat 2 and is used to drive the fixed clamping seat 3 to rotate; the moving drive 6 is mounted on the tooling seat 2 and is used to drive the moving seat 4 to move toward or away from the fixed clamping seat 3; the third rotation drive 6 is mounted on the moving seat 4 and is used to drive the moving clamping seat 5 to rotate.

[0030] Before processing, the movable clamping seat 5 and the fixed clamping seat 3 are in a far apart state, providing sufficient space for the placement of the valve component. During processing, the valve component is placed between the fixed clamping seat 3 and the movable clamping seat 5, so that the valve component is in contact with the required position of the fixed clamping seat 3. Then, the movable seat 4 and the movable clamping seat 5 are driven synchronously towards the fixed clamping seat 3 by the movable drive component, so that the movable seat 5 and the fixed clamping seat 3 clamp and fix the valve component. Then, the valve component is precision-machined by the tool on the machine tool body 1. During the processing, the tooling seat 2 is driven to rotate by the first rotation drive component 6 as needed, so as to move different parts of the valve component to the processing position. Alternatively, the fixed clamping seat 3 and the movable clamping seat 5 are driven synchronously by the second rotation drive component and the third rotation drive component to rotate synchronously, so as to rotate the valve component. At the same time, in conjunction with the rotation capability of the CNC tool head on the machine tool body 1, the valve component can change the processing position as needed. Multiple precision machining can be achieved without frequent disassembly and assembly of the valve component or frequent changes of the valve component's position on the machine tool, which helps to improve processing efficiency.

[0031] Reference Figure 2 and Figure 3 To facilitate the rotation of the tooling seat 2, the first rotation drive 6 is a first hydraulic motor mounted on the machine tool body 1, and the tooling seat 2 is coaxially fixed with the output shaft of the first hydraulic motor; in other embodiments, the first rotation drive 6 may also be a motor, electric motor, etc.

[0032] Reference Figure 2 and Figure 3 To facilitate the rotation of the fixed clamping seat 3 and the movable clamping seat 5, the second rotation drive component includes a second hydraulic motor, and the third rotation drive component includes a third hydraulic motor. The second hydraulic motor is installed in the tooling seat 2, and the fixed clamping seat 3 is coaxially fixed with the output shaft of the second hydraulic motor. The third hydraulic motor is embedded in the movable seat 4, and the movable clamping seat 5 is coaxially fixed with the output shaft of the third hydraulic motor. In other embodiments, the second rotation drive component and the third rotation drive component can also be either an electric motor or an electric motor.

[0033] Reference Figure 2 and Figure 3 The moving drive component includes a hydraulic cylinder installed in the tooling base 2. The moving base 4 is fixedly connected to the moving part of the hydraulic cylinder. In other embodiments, the moving drive component may also be one of a pneumatic cylinder, an electric cylinder, etc.

[0034] In this application, the tooling seat 2, the fixed clamping seat 3, and the movable clamping seat 5 are all rotated by hydraulic drive, and the movement of the movable seat 4 is also driven by hydraulic drive. Hydraulic drive not only has a strong clamping force, but also makes the tooling seat 2, the fixed clamping seat 3, and the movable clamping seat 5 more stable in position after rotation, which helps to ensure stable processing of valve components.

[0035] Reference Figure 3 and Figure 4 To facilitate clamping and fixing of valve components, a first clamping body 10, a second clamping body 11, and a third clamping body 12 are provided on the side of the fixed clamping seat 3 and the movable clamping seat 5 that are close to each other. The first clamping body 10, the second clamping body 11, and the third clamping body 12 on the fixed clamping seat 3 and the movable clamping seat 5 correspond to the three fluid channels 29 respectively. The two first clamping bodies 10, the two second clamping bodies 11, and the two third clamping bodies 12 are used to clamp and fix the end bosses 30 of the corresponding fluid channels 29 respectively.

[0036] By clamping and fixing the end boss 30 of the fluid channel 29 at the corresponding position relative to the two first clamping bodies 10, clamping and fixing the end boss 30 of the fluid channel 29 at the corresponding position relative to the two second clamping bodies 11, and clamping and fixing the end boss 30 of the fluid channel 29 at the corresponding position relative to the two third clamping bodies 12, the clamping of the valve component is made more stable and reliable.

[0037] Reference Figure 4 and Figure 5 To further ensure the clamping and fixing effect, each of the two first clamping bodies 10 has a first contact surface 13 on its side that is close to each other. The first contact surface 13 is used to contact the outer wall of the corresponding fluid channel 29 end boss 30. Each of the two second clamping bodies 11 has a second contact surface 14 on its side that is close to each other. The second contact surface 14 is used to contact the outer wall of the corresponding fluid channel 29 end boss 30. The plane of the second clamping body 11 is parallel to the plane of the first clamping body 10. That is, the two first clamping bodies 10 and the two second clamping bodies 11 are used to clamp the ends of the two fluid channels 29 with parallel axial directions, respectively. Each of the two third clamping bodies 12 has a third contact surface 15 on its side that is close to each other. The third contact surface 15 is used to contact the outer wall of the corresponding fluid channel 29 end boss 30. The plane of the third clamping body 12 is perpendicular to the plane of the second clamping body 11. That is, the third clamping body 12 is used to clamp the end of the remaining fluid channel 29.

[0038] Reference Figure 4 and Figure 5 Specifically, the first mating surface 13, the second mating surface 14 and the third mating surface 15 can be designed as arc-shaped, U-shaped or other shapes according to the shape of the end boss 30 of the corresponding fluid channel 29, so as to adapt to the outer wall of the end boss 30 of the corresponding fluid channel 29 and achieve multi-directional limiting of the fluid channel 29.

[0039] Reference Figure 4 and Figure 5In this embodiment, the first mating surface 13 and the third mating surface 15 are arc-shaped to accommodate the end boss 30 of the fluid channel 29 with circular or elliptical ends; the second mating surface 14 is U-shaped to accommodate the square boss 30 with rounded corners at its ends. The distance between the two first mating surfaces 13 is greater than the distance between the two second mating surfaces 14, and also greater than the distance between the two third mating surfaces 15.

[0040] Reference Figure 4 and Figure 5 A notch 16 is provided through each of the first mating surface 13, the second mating surface 14, and the third mating surface 15. The notch 16 is located at the middle position of the corresponding first mating surface 13, the second mating surface 14, or the third mating surface 15. The extension direction of the notch 16 is perpendicular to the plane of the corresponding first clamping body 10, the second clamping body 11, or the third clamping body 12. The notch 16 facilitates the falling off of finishing debris and prevents the accumulation of machining debris on the machining surface.

[0041] Reference Figure 4 and Figure 5 The first clamping body 10 is integrally formed with the corresponding fixed clamping seat 3 and movable clamping seat 5, respectively. The second clamping body 11 and the third clamping body 12 are detachably fixed to the corresponding fixed clamping seat 3 or movable clamping seat 5 by bolts. By designing the second clamping body 11 and the third clamping body 12 as detachable structures, different second clamping bodies 11 and third clamping bodies 12 can be replaced according to different specifications of valve components, thus expanding the scope of application. Since there is at least one circular boss 30 at the end of the fluid channel 29 in the valve component, the first clamping body 10 is designed as an integrally formed structure.

[0042] Reference Figure 4 and Figure 5 A limiting body 17 is integrally formed on the fixed clamping seat 3 and the movable clamping seat 5. The limiting body 17 is located between the first clamping body 10 and the second clamping body 11. The distance between the two limiting bodies 17 on the fixed clamping seat 3 and the movable clamping seat 5 is less than the distance between the two first contact surfaces 13 on the same side, so that the side of the limiting body 17 near the first clamping body 10 has a limiting surface. The limiting surface of the limiting body 17 near the first contact surface 13 is used to abut against the surface of the end boss 30 of the fluid channel 29 corresponding to the first contact surface 13.

[0043] When the valve component needs to be placed between the fixed clamping seat 3 and the movable clamping seat 5, the surface of the end boss 30 of the fluid channel 29 on the valve component is respectively fitted and abutted with the corresponding mating surface, and the surface of the end boss 30 at the position of the first clamping body 10 on the valve component near the second clamping body 11 abuts with the surface of the limiting body 17, thereby achieving the positioning of the valve component.

[0044] Reference Figure 5 To ensure the synchronous rotation of the movable clamping seat 5 and the fixed clamping seat 3, a guide rod 27 is bolted to the fixed clamping seat 3. The guide rod 27 has a rectangular cross-section and is located away from the first clamping body 10, the second clamping body 11, and the third clamping body 12 to avoid affecting the placement and removal of valve components. The length direction of the guide rod 27 is parallel to the rotation axis of the fixed clamping seat 3. The movable clamping seat 5 has a guide groove 28 that slides with the guide rod 27. Through the sliding engagement of the guide rod 27 and the guide groove 28, the synchronous rotation of the movable clamping seat 5 and the fixed clamping seat 3 is ensured, and the sliding of the movable seat 4 is guided to ensure the positional accuracy of the tooling.

[0045] The implementation principle of Embodiment 1 of this application is as follows: Before processing, the movable clamping seat 5 and the fixed clamping seat 3 are in a state of being far apart, and the two first clamping bodies 10, two second clamping bodies 11 and two third clamping bodies 12 on the fixed clamping seat 3 and the movable clamping seat 5 are in an aligned state, providing sufficient space for the valve component to be placed.

[0046] During processing, the valve component is gradually placed between the fixed clamping seat 3 and the movable clamping seat 5 from between the two first clamping bodies 10 toward the direction closer to the second clamping body 11. Then, the protrusions 30 at the ends of each fluid channel 29 of the valve component are respectively made to fit with the first contact surface 13, the second contact surface 14 and the third contact surface 15 on the fixed clamping seat 3, and the end protrusions 30 of the fluid channel 29 at the first contact surface 13 abut against the limiting surface of the limiting body 17. Then, the movable seat 4 and the movable clamping seat 5 are driven by the movable drive to move synchronously toward the direction closer to the fixed clamping seat 3 until the movable clamping seat 5 and the fixed clamping seat 3 clamp and fix the end protrusions 30 of each fluid channel 29 of the valve component. Finally, the valve component is precision machined by the cutting tool on the machine tool body 1.

[0047] During the processing, the tooling seat 2 is driven to rotate by the first rotary drive 6 as needed, so as to move different parts of the valve component to the processing position, and / or the fixed clamping seat 3 and the movable clamping seat 5 are driven to rotate synchronously by the second and third rotary drive components, so as to drive the valve component to rotate. In addition, with the rotation capability of the CNC tool head on the machine tool body 1, the valve component can change the processing position as needed. Multiple finishing operations can be achieved without frequent disassembly and assembly of the valve component or frequent changes of the valve component's position on the machine tool, which helps to improve processing efficiency and combines multiple finishing positions into one.

[0048] Example 2:

[0049] Reference Figure 6 , Figure 7 and Figure 8The difference between this embodiment and embodiment 1 is that the first clamping body 10, the second clamping body 11 and the third clamping body 12 are all provided with a mounting groove 18 on the side away from the center of the corresponding fixed clamping seat 3 or the movable clamping seat 5. A slider 19 is slidably disposed in the mounting groove 18. The sliding direction of the slider 19 is parallel to the rotation axis of the fixed clamping seat 3. Specifically, the cross-section of the slider 19 and the mounting groove 18 can be designed as a dovetail shape or a T shape so that the slider 19 will not detach from the mounting groove 18.

[0050] Reference Figure 6 , Figure 7 and Figure 8 A limiting plate 20 is fixed on the side of the slider 19 away from the bottom wall of the corresponding mounting groove 18. The limiting plate 20 is used to abut against the end face of the end boss 30 of the fluid channel 29 at the corresponding position. An adjustment component is provided in the mounting groove 18 for adjusting the slider 19 to slide so that the limiting plate 20 extends or retracts to the corresponding first clamping body 10, second clamping body 11 or third clamping body 12.

[0051] When the fixed clamping seat 3 and the movable clamping seat 5 drive the valve component to rotate so that the machining surface faces upward and the unmachined surface faces downward, the adjusting assembly adjusts the downward-facing limiting plate 20 to extend towards the valve component, so that the limiting plate 20 abuts against the end face of the downward-facing fluid channel 29 end boss 30, thereby limiting the entire valve component and preventing the valve component from moving in the machining direction under the abutment of the cutting tool.

[0052] Reference Figure 6 , Figure 7 and Figure 8To facilitate the adjustment of the slider 19 to drive the limiting plate 20 to slide, the adjustment assembly includes a counterweight 21 and an elastic reset component. Each of the first clamping body 10, the second clamping body 11, and the third clamping body 12 has a sliding cavity 24. The depth direction of the sliding cavity 24 is perpendicular to the plane of the corresponding first clamping body 10, second clamping body 11, or third clamping body 12. The sliding cavity 24 is located on the side of the corresponding mounting groove 18 away from the valve component. The counterweight 21 corresponds one-to-one with the sliding cavity 24, and the counterweight 21 is slidably disposed within the corresponding sliding cavity 24. The sliding direction of the counterweight 21 is parallel to the depth direction of the corresponding sliding cavity 24. Furthermore, the sliding direction of the counterweight 21 is perpendicular to the rotation axis of the fixed clamping seat 3. The counterweight 21 is cylindrical and is located on the corresponding limiting plate 20 near the mounting groove 18. On one side, a stop block 25 is fixed on the side of the limiting plate 20 near the corresponding counterweight 21. The first clamping body 10, the second clamping body 11 and the third clamping body 12 are all provided with connecting grooves. The connecting grooves are aligned with the corresponding sliding cavities 24. The connecting grooves are located on the side of the corresponding mounting groove 18 away from the valve component. The stop block 25 slides in the connecting groove. The side of the stop block 25 near the sliding cavity 24 has an arc surface 22. The distance from the arc surface 22 to the bottom wall of the sliding cavity 24 increases in the direction away from the valve component. A stop rod 26 is fixed on the counterweight 21. The stop rod 26 slides out of the sliding cavity 24 and extends into the connecting groove. The stop rod 26 is used to slide relative to the arc surface 22 on the stop block 25. In order to improve the relative sliding effect, the end of the stop rod 26 away from the counterweight 21 can be designed as an outwardly convex arc surface.

[0053] Reference Figure 6 , Figure 7 and Figure 8 When the counterweight 21 moves away from the bottom wall of the sliding cavity 24, causing the abutment rod 26 to slide relative to the arc surface 22 on the abutment block 25, the abutment rod 26 pushes the abutment block 25 and the limiting plate 20 to move closer to the valve component. The elastic reset member is set in the mounting groove 18. The elastic reset member is used to drive the slider 19 to move the limiting plate 20 away from the valve component to reset. The weight of the counterweight 21 is greater than the elastic force of the elastic reset member.

[0054] Reference Figure 6 , Figure 7 and Figure 8To facilitate the movement of the slider 19 and the limiting plate 20 away from the valve component, the elastic reset component includes a spring 23. The spring 23 is disposed in the corresponding mounting groove 18 and is located on the side of the corresponding slider 19 near the abutment block 25. One end of the spring 23 is fixed on the side of the slider 19 away from the valve component, and the other end is fixed on the inner wall of the mounting groove 18 on the side away from the valve component. The weight of the counterweight 21 is greater than the elastic force of the spring 23, and the elastic force of the spring 23 is greater than the sum of the weights of the slider 19 and the limiting plate 20. When the counterweight 21 abuts against the bottom wall of the slide cavity 24, the abutting rod 26 disengages from the surface of the abutting block 25, and the spring is in its natural state. When the spring 23 is in its natural state, the distance between the limiting plate 20 and the center of the end of the corresponding fluid channel 29 is less than the distance between the first contact surface 13, the second contact surface 14, or the third contact surface 15 at the corresponding position and the center of the end of the corresponding fluid channel 29. That is, the limiting plate 20 does not extend out of the corresponding first clamping body 10, the second clamping body 11, or the third clamping body 12. When the slider 19 abuts against the side of the corresponding mounting groove 18 near the valve component, the end of the abutting block 25 away from the valve component is aligned with the abutting rod 26, so that the abutting rod 26 and the counterweight 21 will not fall out of the corresponding slide cavity 24.

[0055] The implementation principle of Embodiment 2 of this application is as follows: When the end boss 30 of the corresponding fluid channel 29 held by the first clamping body 10, the second clamping body 11 or the third clamping body 12 faces upward, the counterweight 21 will abut against the bottom wall of the slide cavity 24 under the gravity of the counterweight 21. At this time, the abutting rod 26 on the counterweight 21 disengages from the corresponding abutting block 25, the spring 23 is in its natural state, and the limiting plate 20 disengages from the valve component, which will not affect the tool from processing the upward-facing fluid channel 29.

[0056] When the corresponding fluid channel 29 held by the first clamping body 10, the second clamping body 11, or the third clamping body 12 faces downward, under the gravity of the counterweight 21, the counterweight 21 will move away from the bottom wall of the slide cavity 24, causing the abutment rod 26 to push the abutment block 25 to slide relative to the arc surface 22, causing the slider 19 and the limiting plate 20 to move towards the valve component, and the spring 23 to stretch and deform until the slider 19 abuts against the inner wall of the mounting groove 18 near the valve component. At this time, the limiting plate 20 abuts against the end face of the end boss 30 at the corresponding position of the valve component, so as to prevent the entire valve component from moving downward under the force of the tool and improve the machining reliability.

[0057] When the corresponding fluid channel 29 held by the first clamping body 10, the second clamping body 11, or the third clamping body 12 is oriented in the horizontal direction, the side wall of the sliding cavity 24 supports the counterweight 21. The elastic force of the spring 23 is greater than the frictional force of the counterweight 21. Under the action of the elastic force of the spring 23, the limiting plate 20 will remain in the unextended state, that is, the limiting plate 20 is detached from the valve component, and will not affect the tool from machining the end boss 30 of the fluid channel 29 facing the horizontal direction.

[0058] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
