Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of machining, especially relates to a thin-walled pipe fitting machining auxiliary device. BACKGROUND
[0002] Thin-walled parts have been increasingly widely applied in various industrial departments because it has the characteristics of light weight, material saving, compact structure and the like, but due to the self characteristics of thin-walled parts, in actual operation, it is influenced by cutting force, cutting heat, machine tool fixture, tool and the like, so that the turning and milling of thin-walled parts become a very thorny problem in machining, the reason is that thin-walled parts have poor rigidity and weak strength, and are extremely easy to deform in machining, so that the shape and position error of the parts is increased, and it is not easy to guarantee the machining quality of the parts.
[0003] With the continuous development of the field of semiconductor precision machining, the technology and method matched therewith also need to be continuously upgraded, and the machining of thin-walled parts is one of them, the traditional machining cannot machine thin-walled parts, and has many shortcomings such as deformation, tool shock, wall breaking, eccentricity, high product scrap rate, and cannot reach the machining purpose, which affects the limitation of machining metal thin-walled parts. In the machining process, the thickness of the thin-walled part to be obtained is too thin and the space is large, and in the machining process, the tool is easy to shock and deform, so that the thin-walled part cannot be machined. CONTENT OF THE UTILITY MODEL
[0004] The utility model can provide an auxiliary device capable of preventing deformation of thin-walled parts in machining.
[0005] The utility model scheme is: a thin-walled pipe fitting machining auxiliary device, including circular cover plate, be equipped with fixed plate on the cover plate, and movable plate with the same side as the fixed plate and can move along the radial direction of the cover plate;The center of the cover plate is provided with a conical piston hole, and the piston hole is matched with a conical piston, the length of the piston is greater than the thickness of the cover plate, and the large end is on the same side as the fixed plate;The center of the piston is provided with a perfusion hole, the perfusion hole is circumscribed with a flowing paraffin tube, and a one-way valve is arranged at the orifice on the same side as the fixed plate in the perfusion hole;The side wall of the piston is provided with a mark line.
[0006] The beneficial effects are as follows: This utility model provides an auxiliary device for processing thin-walled pipe fittings. A fixed plate and a movable plate clamp the thin-walled fitting within them. Flowing paraffin wax is then injected into the cavity of the thin-walled fitting through a flowing paraffin wax tube connected to a piston. When the level of the flowing paraffin wax rises to the conical piston, it cannot flow backward along the one-way valve, but it pushes the large end of the conical piston along the piston hole, eventually pressing against it. At this point, the marking line is visible outside the cover plate, and the injection stops. After the paraffin wax cools and solidifies, this auxiliary device reinforces both ends of the thin-walled fitting, making the subsequent processing of the middle section and both ends more stable. This auxiliary device can reinforce the ends of thin-walled fittings, and by injecting paraffin wax, the cooled paraffin wax fills the thin-walled fitting, making it a solid body, thus preventing deformation during processing.
[0007] Furthermore, the cover plate is provided with a sliding groove arranged radially thereon, and one end of the movable plate is provided with a slider that cooperates with the sliding groove. The slider is provided with a positioning screw. When the movable plate moves to clamp the thin-walled part, the positioning screw is used to fix it.
[0008] Furthermore, the piston is a stainless steel piston. When it is necessary to remove the auxiliary device for processing thin-walled pipes, if there is any adhesion between the piston and paraffin wax, the paraffin wax at the adhesion point can be melted by heating the stainless steel piston, making it easier to remove.
[0009] Furthermore, the small end of the piston is provided with a hook, which is hung on the cover plate, so that the piston can be suspended in the piston hole to achieve the effect of leaving a gap.
[0010] Furthermore, the fixed plate and the movable plate are arc-shaped plates, which facilitates clamping of cylindrical thin-walled parts. Attached Figure Description

[0013] like Figure 1 As shown, a thin-walled pipe processing auxiliary device includes a circular cover plate 1, on which a fixed plate 2 and a movable plate 3 are provided. The fixed plate 2 is integrally formed with the cover plate 1 or bolted to it. A sliding groove 4 is formed on the surface of the cover plate 1 along its radial direction. One end of the movable plate 3 is equipped with a slider, which slides in cooperation with the sliding groove 4. The slider is equipped with a positioning screw 5. After the movable plate 3 moves to the target position, it is pressed against the groove wall of the sliding groove 4 by the positioning screw 5.
[0014] The center of the cover plate 1 is provided with a piston hole 6, which is a tapered hole, and the hole diameter of the piston hole 6 on the same side of the fixed plate 2 is larger than that on the other side. A tapered piston 7 is matched in the piston hole 6, the length of the tapered piston 7 is larger than the thickness of the cover plate 1, and in the non-working state, a gap is left between the piston 7 and the piston hole 6 (a hook can be arranged at the small end of the piston 7, and the hook is hung on the cover plate 1, so that the piston 7 can be suspended in the piston hole 6 to achieve the effect of leaving a gap), and the large end of the piston 7 is on the same side of the fixed plate 2. The center of the piston 7 is provided with a pouring hole, the pouring hole is circumscribed by a flowing paraffin pipe 8, and a one-way valve 9 is arranged at the hole opening on the same side of the fixed plate 2. The one-way valve 9 is opened outward from the inside.
[0015] When the embodiment is used, the open end of the thin-walled part is placed between the fixed plate 2 and the movable plate 3, the movable plate 3 is moved to make the sliding block move in the sliding groove 4, and when the movable plate 3 clamps the thin-walled part, the positioning screw 5 of the sliding block is tightened to make the movable plate 3 and the fixed plate 2 clamp the thin-walled part. According to the operation, the other open end of the thin-walled part is installed with the thin-walled pipe part processing auxiliary device, and at this time, the pouring cavity is formed in the thin-walled part. The pressure pump of the flowing paraffin pipe 8 is opened, so that the flowing paraffin enters the pouring cavity along the pouring hole and the one-way valve 9, and when the flowing paraffin liquid surface rises to the tapered piston 7, the flowing paraffin cannot flow in the reverse direction along the one-way valve 9 (at the same time, the pressure of the pressure pump cannot also flow in the reverse direction), but can push the large end of the tapered piston 7 to move along the piston hole 6, and finally abut against the piston hole 6. At this time, the mark line 10 is exposed outside the cover plate 1 and is observed, and at this time, the pouring is stopped. After the paraffin is cooled and solidified, the processing auxiliary device of the embodiment plays a reinforcing role on the two ends of the thin-walled part, and the middle section and the two ends of the thin-walled part are more stable. When only one end of the thin-walled part needs to be processed, the processing auxiliary device of the corresponding end can be removed.
[0016] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be regarded as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
