Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically a composite fixture for valve body processing. Background Technology

[0002] The application of composite fixtures in valve body machining is a key choice for improving efficiency and ensuring accuracy, especially adapting to the machining characteristics of valve bodies with multiple specifications and processes. Its core adaptability solves the problem of compatibility among multiple specifications: valve bodies have large differences in diameter and structure. Composite fixtures can quickly adjust the positioning and clamping methods through standardized module combinations, eliminating the need to customize special fixtures for each model. It adapts to the needs of complex processes. Valve bodies need to complete multiple processes such as end face milling, positioning hole drilling, internal hole boring, and sealing surface machining. Composite fixtures support the completion of multiple processes in one clamping, reducing clamping errors.

[0003] Patent publication number "CN216912210U" discloses a composite fixture for valve body processing, comprising a base, a base plate fixedly mounted on the front side of the base, a three-jaw chuck fixedly mounted on the front side of the base plate, insertion holes on the front sides of both the base plate and the three-jaw chuck, a collar provided on the outer side of the three-jaw chuck, a rod fixedly mounted on the front side of the collar with one end penetrating the collar and extending into the insertion hole, and a mounting seat located on the front side of the base fixedly mounted on the outer side of the collar, with a mounting rod provided on the front side of the mounting seat. This composite fixture for valve body processing has advantages such as good fixing effect, solving the problem that in the current process of drilling medium and large valve body flanges, the valve body is fixed by a horizontally set three-jaw chuck, but the contact area between the bottom flange of medium and large valve bodies and the three-jaw chuck is small, resulting in poor fixing effect of the valve body.

[0004] In the aforementioned patent, the existing composite fixture can only hold one valve body at a time, which affects the processing efficiency of the valve body. Furthermore, it lacks a good auxiliary cleaning function, making it troublesome to clean up processing debris, thus affecting the performance.

[0005] Therefore, this utility model provides a composite fixture for valve body processing to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a composite fixture for valve body processing, which solves the problem that existing composite fixtures can only hold one valve body at a time, thus affecting the processing efficiency of the valve body.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a composite fixture for valve body processing, comprising a worktable, a flipping cleaning assembly fixedly mounted on the top of the worktable, a clamping assembly fixedly mounted on the top of the flipping cleaning assembly, and a control panel fixedly mounted on the top of the flipping cleaning assembly; the clamping assembly comprises a stabilizing frame and a second spring, the stabilizing frame fixedly mounted on the top of the flipping cleaning assembly, the second spring sleeved on the side wall of the stabilizing frame, a first clamping plate slidably connected to the side wall of the stabilizing frame, a second clamping plate fixedly mounted on the top of the flipping cleaning assembly, a trapezoidal block fixedly mounted on one side of the first clamping plate, an electric push rod fixedly mounted on the top of the flipping cleaning assembly, a wheel fixedly connected to the output end of the electric push rod, and an electrical connection between the control panel and the electric push rod.

[0008] Furthermore, the clamping assembly also includes a limiting block, which is fixedly connected to one end of the stabilizer.

[0009] Using the above technical solution, the limiting block can accurately limit the valve body end, avoid axial displacement during processing, and improve clamping stability.

[0010] Furthermore, the clamping assembly also includes a stabilizing groove, which is formed on the top of the flip cleaning assembly, and the clamping plate is slidably connected to the stabilizing groove.

[0011] Using the above technical solution, the stabilizing groove provides guidance for the clamping plate, ensuring smooth clamping action and reducing clamping deviation.

[0012] Furthermore, the flip cleaning assembly includes a U-shaped frame and a rotating plate, the U-shaped frame being fixedly mounted on the top of the workbench, and the rotating plate being hinged to the top of the U-shaped frame.

[0013] Using the above technical solution, the rotating plate can be flipped around the U-shaped frame, which facilitates cleaning from multiple angles or adjustment of the processing position.

[0014] Furthermore, the flip cleaning assembly also includes a slide rod, which is slidably connected to one side of the workbench. A spring is sleeved on the side wall of the slide rod, and a movable plate is fixedly connected to one end of the slide rod. A locking plate is fixedly installed on one side of the movable plate, and the locking plate is engaged with the rotating plate.

[0015] Using the above technical solution, the spring pushes the clamping plate to lock the rotating plate, achieving stable positioning after flipping, and making operation convenient.

[0016] Furthermore, the flip cleaning assembly also includes a pull ring, which is fixedly connected to one end of the slide bar.

[0017] By adopting the above technical solution, the pull ring makes it easy to pull the slide bar to unlock, saving effort and improving the convenience of the flipping operation.

[0018] Furthermore, the flip cleaning assembly also includes a support frame, which is fixedly installed on the top of the workbench and located below the rotating plate.

[0019] By adopting the above technical solution, the support frame is supported after the rotating plate flips, avoiding deformation under stress and extending the life of the component.

[0020] Beneficial effects

[0021] This invention provides a composite fixture for valve body machining. Compared with the prior art, it has the following advantages:

[0022] 1. This composite fixture for valve body machining, through its clamping components, can clamp valve bodies simultaneously, improving machining efficiency and doubling processing efficiency. It reduces the number of clamping operations and waiting time per batch. The clamping components use adjustable positioning pins and elastic clamping mechanisms to adapt to valve bodies of different diameters and structures. The synchronicity of dual-station clamping ensures consistency in batch processing, reducing dimensional deviations caused by multiple clamping operations. It is especially suitable for small to medium batch production with multiple specifications, significantly shortening the production cycle and improving capacity and processing cost-effectiveness.

[0023] 2. This composite fixture for valve body machining, through its set-on flipping cleaning component, can assist in cleaning the debris generated during machining, preventing debris from accumulating on critical parts such as the valve body sealing surface and inner hole, thus avoiding scratching precision machined surfaces or affecting the positioning accuracy of subsequent processes. The cleaning component, in conjunction with the flipping action, uses high-pressure airflow or brushes to achieve all-round debris cleaning without the need for machine downtime for manual cleaning, reducing machining auxiliary time, ensuring the cleanliness of the machining environment, reducing the impact of debris on tool life, and further improving the overall machining stability and product qualification rate.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4This application provides a composite fixture for valve body processing, including a worktable 1. A flip cleaning assembly 2 is fixedly installed on the top of the worktable 1, a clamping assembly 3 is fixedly installed on the top of the flip cleaning assembly 2, and a control panel 4 is fixedly installed on the top of the flip cleaning assembly 2. The clamping assembly 3 includes a stabilizing frame 31 and a second spring 32. The stabilizing frame 31 is fixedly installed on the top of the flip cleaning assembly 2, the second spring 32 is sleeved on the side wall of the stabilizing frame 31, and a clamping plate 33 is slidably connected to the side wall of the stabilizing frame 31. The flip cleaning assembly 2... The top of the first clamping plate 33 is fixedly installed with a clamping plate 34, and a trapezoidal block 36 is fixedly installed on one side of the first clamping plate 33. The top of the flip cleaning assembly 2 is fixedly installed with an electric push rod 37, and a wheel 38 is fixedly connected to the output end of the electric push rod 37. The control panel 4 is electrically connected to the electric push rod 37. The clamping assembly 3 also includes a limiting block 39, which is fixedly connected to one end of the stabilizer 31. The clamping assembly 3 also includes a stabilizing groove 35, which is opened on the top of the flip cleaning assembly 2. The first clamping plate 33 and the stabilizing groove 35 are slidably connected.

[0033] In this embodiment, during operation, the control panel 4 controls the electric push rod 37 to start, and its output end pushes the wheel 38 to contact the trapezoidal block 36, forcing the clamping plate 33 to slide along the side wall of the stabilizer 31 and compress the spring 32. At this time, a clamping space is formed between the clamping plate 33 and the clamping plate 34. After the valve body is placed in, the electric push rod 37 resets, and the spring 32 rebounds to push the clamping plate 33 to reset, cooperating with the clamping plate 34 to complete the clamping of the valve body. The stabilizing groove 35 provides sliding guidance for the clamping plate 33 to avoid displacement; the limiting block 39 limits the end of the valve body to prevent axial movement, ensure clamping accuracy and stability, and adapt to the quick clamping requirements of valve bodies of different specifications. The control panel 4 is model PLC-200SmartSR20.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the flip cleaning assembly 2 includes a U-shaped frame 21 and a rotating plate 22. The U-shaped frame 21 is fixedly installed on the top of the workbench 1, and the rotating plate 22 is hinged to the top of the U-shaped frame 21. The flip cleaning assembly 2 also includes a slide rod 23, which is slidably connected to one side of the workbench 1. A spring 24 is sleeved on the side wall of the slide rod 23. A movable plate 25 is fixedly connected to one end of the slide rod 23. A locking plate 26 is fixedly installed on one side of the movable plate 25. The locking plate 26 is engaged with the rotating plate 22. The flip cleaning assembly 2 also includes a pull ring 27, which is fixedly connected to one end of the slide rod 23. The flip cleaning assembly 2 also includes a support frame 28, which is fixedly installed on the top of the workbench 1 and is located below the rotating plate 22.

[0035] In this embodiment, when it is necessary to clean processing debris or adjust the processing angle of the valve body, pulling the pull ring 27 moves the slide rod 23, causing the moving plate 25 to move the clamping plate 26 away from the rotating plate 22. At this time, the rotating plate 22 can rotate around the hinge point of the U-shaped frame 21 to realize the adjustment of the valve body angle. After releasing the pull ring 27, the spring 24 pushes the slide rod 23 to reset, and the clamping plate 26 re-clamps the rotating plate 22 to complete the positioning. During the rotation process, the support frame 28 forms a bottom support for the rotating plate 22 to avoid deformation under force. The rotation action, together with the external cleaning device, can clean the valve body surface and inner cavity debris in all directions, ensuring the cleanliness of the processing environment and the accuracy of subsequent processes.

[0036] Working principle: During operation, the control panel 4 controls the electric push rod 37 to start, and its output end pushes the wheel 38 to contact the trapezoidal block 36, forcing the clamping plate 33 to slide along the side wall of the stabilizer 31 and compress the spring 32. At this time, a clamping space is formed between the clamping plate 33 and the clamping plate 34. After the valve body is placed in, the electric push rod 37 returns to its original position, and the spring 32 rebounds to push the clamping plate 33 to return to its original position, cooperating with the clamping plate 34 to complete the clamping of the valve body. The stabilizing groove 35 provides sliding guidance for the clamping plate 33 to avoid displacement; the limiting block 39 limits the end of the valve body to prevent axial movement, ensuring clamping accuracy and stability, and adapting to the quick clamping needs of valve bodies of different specifications.

[0037] When it is necessary to clean machining debris or adjust the machining angle of the valve body, pull the pull ring 27 to move the slide rod 23, so that the moving plate 25 drives the clamping plate 26 to disengage from the rotating plate 22. At this time, the rotating plate 22 can rotate around the hinge point of the U-shaped frame 21 to realize the adjustment of the valve body angle. After releasing the pull ring 27, the spring 24 pushes the slide rod 23 to reset, and the clamping plate 26 re-clamps the rotating plate 22 to complete the positioning. During the rotation process, the support frame 28 forms a bottom support for the rotating plate 22 to avoid deformation under force. The rotation action, together with the external cleaning device, can clean the valve body surface and internal cavity debris from all directions, ensuring the cleanliness of the machining environment and the accuracy of subsequent processes.
