Description
Technical Field
[0001] This utility model relates to the field of milling device technology, specifically a convenient adjustable flange end face milling processing device. Background Technology
[0002] A flange is a ring-shaped connector with bolt holes, usually used in conjunction with pipes, equipment interfaces, valves and other components. It achieves a detachable and sealed connection between two components by tightening bolts. Its core function is to ensure the sealing performance, strength and ease of assembly and maintenance of the connection. Its material must be suitable for the working conditions and it has a variety of structural forms. It is widely used in petrochemical, construction, machinery, pipeline systems, rail transit engineering and other fields. It is a key basic component for connecting components in industrial production. The flange end face milling processing device is a specialized machining equipment for precise control of flange thickness. Equipped with an adjustable milling mechanism, positioning and clamping components, and a precision detection unit, it can perform targeted milling processing on the end face of flange blanks. It can accurately remove excess material from the end face, correct thickness deviations, and ensure the consistency of flange thickness after milling and the perpendicularity of the end face to the center hole. Ultimately, it ensures that the flange thickness meets the assembly and sealing requirements, ensuring uniform stress and reliable sealing when connected to supporting components. It is widely used in the mass production or customized processing of flanges of various specifications. In the scenario of double-sided flange milling, the traditional machining solution adopts the clamping method of directly placing the flange flat on the worktable. Since the initial end face of the flange may have flatness deviation, it is easy to form a natural tilt on the worktable when placed directly. This tilt, combined with the positioning error that is not specifically compensated during the clamping process, will cause the flange machining datum to shift, ultimately resulting in the end face parallelism of the machined flange not meeting the standard. This leads to assembly defects such as bolt hole alignment deviation and excessive sealing surface fit gap in the subsequent assembly stage. Therefore, a convenient adjustable gap flange end face milling device is proposed to address the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a convenient adjustable flange end face milling device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A convenient adjustable flange end face milling device includes a milling machine.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-7 This utility model provides a technical solution: A convenient adjustable flange end face milling processing device includes a milling machine 1. A support component 2 is fixedly connected to one end of the milling machine 1. A guide component 3 is fixedly connected to the upper end of the support component 2. A calibration and positioning component 4 is installed inside the guide component 3. The guide component 3 includes an assembly plate 31. The calibration and positioning component 4 includes a clamping column 41. Two spiral strips 42 are provided on the upper and lower parts of the clamping column 41. The clamping column 41 is threadedly connected to the threaded hole 44 of the sleeve 43 through the spiral strips 42. A ball groove 45 is provided inside the sleeve 43. A spherical shell 46 is embedded in the ball groove 45. A pressure plate 47 is fixedly connected to one end of the spherical shell 46. An expansion hole 48 is provided inside the spherical shell 46. An embedding cavity 49 is provided between the two pressure plates 47 in the same group.
[0017] As a further implementation of this solution, the support component 2 includes a base plate 21. A chuck 22 and a support frame 23 are fixedly connected to the top of the base plate 21. A gap is provided between one side of the support frame 23 and the outer side of the chuck 22. The bottom end of the base plate 21 is fixedly connected to the slide plate of the milling equipment 1. The side of the support frame 23 near the upper end is fixedly connected to the outer side of the assembly plate 31. Through the above-mentioned arrangement, this fixed connection method realizes the stable integration of the positioning mechanism and the milling equipment 1, so that the flange after positioning can be accurately aligned with the milling component, reducing the position deviation during the processing. At the same time, the support frame 23 provides stable support for the assembly plate 31, improves the overall rigidity of the positioning component, avoids the influence of milling vibration on the positioning accuracy, and helps to ensure that the parallelism of the flange end face meets the standard. As a further implementation of this solution, a groove 32 is provided on the inner side of the assembly plate 31. A guide post 33 is fixedly connected to the inner side of the groove 32. The guide post 33 is slidably connected to the guide hole 35 of the slider 34. The slider 34 is embedded in the groove 32. Through the above arrangement, the sliding cooperation between the slider 34 and the guide hole 35 and the embedded design of the slider 34 in the groove 32 form a double guide structure, which greatly improves the stability of the slider 34 movement, effectively prevents it from deviating when it drives the clamping post 41 to contact the flange, and disperses the force transmitted by the clamping post 41, reduces the shear force on the chuck 22 claws, extends the service life of the components, and ensures that the flange shaft can be stably vertical during the positioning process. As a further implementation of this solution, the bottom end of the slider 34 is fixedly connected to the top end of the jaws of the chuck 22, and the top end of the slider 34 is fixedly connected to the bottom end of the clamping column 41. Through the above settings, this connection structure establishes a stable power transmission path from the chuck 22 to the clamping column 41, enabling the chuck 22 to accurately control multiple clamping columns 41 to move towards the flange synchronously. Through the coordinated contact between the clamping column 41 and the outer surface of the flange, the flange axis can be quickly aligned and vertically positioned, avoiding the reference offset problem caused by asynchronous positioning, and providing a prerequisite guarantee for the subsequent milling accuracy. As a further implementation of this solution, a gap is provided between the two spiral strips 42, and the number of spiral strips 42 corresponds one-to-one with the number of sleeves 43. Through the above setting, the gap design provides independent operation and adjustment space for each spiral strip 42, corresponding sleeve 43, pressure plate 47 and other components, which makes it convenient for the staff to make precise adjustments to each pressure plate 47, ensuring that each pressure plate 47 can be tightly attached to the flange end face, realizing the stable fixation of the flange, while avoiding mutual interference between components during the adjustment process, and improving the convenience and accuracy of positioning operation; As a further implementation of this solution, a quarter of the volume of the spherical shell 46 is located outside the spherical groove 45. A gap is provided between the pressure plate 47 and the sleeve 43. The opening diameter of the expansion hole 48 is 1.3 times the opening diameter of the threaded hole 44. The axis of the expansion hole 48 is aligned vertically with the axis of the threaded hole 44. A gap is provided between the expansion hole 48 and the threaded hole 44. Through the above settings, the partially exposed design of the spherical shell 46 provides it with sufficient torsional space. Combined with the size and positional relationship of the expansion hole 48 and the threaded hole 44, it ensures that the pressure plate 47 can freely twist with the inclination of the flange end face, so that the pressure plate 47 is always in close contact with the flange end face, realizing the self-adaptive fixation of the flange. This avoids the problem of unstable fixation caused by uneven end face in traditional clamping. At the same time, the gap between the pressure plate 47 and the sleeve 43 avoids mutual interference during torsion, ensuring the flexibility and reliability of the positioning mechanism.
[0018] Workflow: Before milling the flange, the flange is positioned between multiple mounting cavities 49. Multiple sliders 34 are moved simultaneously by the chuck 22. The sliders 34 slide outside the guide post 33 through the guide hole 35, and simultaneously slide inside the groove 32. The cooperation between the sliders 34 and the guide post 33 improves the stability of the slider movement, preventing the clamping post 41 from contacting the flange and causing the slider 34 to shift. It also reduces the shear force on the chuck 22 jaws. The movement of the slider 34 causes multiple clamping posts 41 to simultaneously move towards the flange. As the flange approaches and contacts multiple clamping posts 41, the contact between the clamping posts 41 and the outer surface of the flange ensures that the flange's axis is vertical. Rotating the sleeve 43, which is threaded into the spiral bar 42 via the threaded hole 44, causes the sleeve 43 to move the spherical shell 46 and the pressure plate 47. When the end face of the pressure plate 47 contacts the flange, it twists with the inclination of the flange end face. The pressure plate 47 twists around the center of the spherical shell 46, causing the spherical shell 46 to twist. At this time, the spherical shell 46 twists inside the ball groove 45, expanding the hole 4... The setting of the opening diameter of 8 and the spacing between the pressure plate 47 and the sleeve 43 will not affect the normal torsion of the spherical shell 46 until the pressure plate 47 is tightly attached to the flange end face. Then, the other sleeve 43 in the same group is operated, and then the other sleeves 43 are operated, thereby achieving the effect of fixing the flange. At this state, the flange is not only vertical on the axis, but also stably fixed. The flange end face is then milled by the milling machine 1. The position of the milling cutter is adjusted by the linear motor of the milling machine 1, thereby achieving the effect of adjusting the distance. During the flange milling process, the part pressed by the pressure plate 47 cannot be... After milling other parts, multiple sleeves 43 at the upper end are operated to loosen the gap between the pressure plate 47 and the flange, rotate the flange, and re-fix the flange. Then, milling is performed on other parts to achieve the milling of the flange end face. Based on the above principles, the device can control the perpendicularity of the flange for positioning without the flange contacting the worktable surface. This can prevent the flange from having flatness deviations before milling, which would cause the flange processing reference to shift. It ensures that the parallelism of the flange end face meets the standard after processing, providing a qualified guarantee for the bolt hole alignment and sealing surface fitting gap in the subsequent assembly stage.
