Description

Technical Field

[0001] This invention relates to the field of titanium alloy tube processing technology, and in particular to a device for removing oxide layers from titanium alloy tubes. Background Technology

[0002] Titanium alloys, as a lightweight, high-strength, and corrosion-resistant alloy material, are widely used in aerospace, medical, and chemical industries. However, during the production and use of titanium alloy tubes, an oxide layer often forms on their surface. This not only affects the aesthetics of the titanium alloy tubes but may also have a potential impact on their performance and service life. Therefore, it is particularly important to effectively remove the oxide layer from the surface of titanium alloy tubes.

[0003] Traditional methods for removing oxide layers from titanium alloy pipes often rely on chemical corrosion or acid pickling. However, these methods are not only complex to operate, but also pose risks to the environment and operators. In recent years, with the continuous advancement of machining technology, mechanical grinding has become a safer and more efficient way to remove oxide layers from titanium alloy pipes.

[0004] In the mechanical grinding process, ensuring that the titanium alloy tube is subjected to uniform and effective grinding during rotation is the key to improving grinding efficiency and quality. Therefore, developing a device that can precisely control the position of the grinding block while ensuring the stable rotation of the titanium alloy tube during grinding has become an urgent need in the industry. Summary of the Invention

[0005] This invention provides a device for removing oxide layers from titanium alloy tubes, in order to solve the problem of how to ensure that titanium alloy tubes are subjected to uniform and effective grinding during rotation.

[0006] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0007] A device for removing oxide layer from titanium alloy tubes, including a mounting base;

[0008] The upper surface of the mounting base is provided with a clamping mechanism for clamping the titanium alloy tube and a grinding mechanism for grinding the titanium alloy tube, and the titanium alloy tube can rotate relative to the grinding mechanism.

[0009] The grinding mechanism includes a mounting bracket that slides perpendicularly to the titanium alloy tube, and two arc-shaped grinding blocks are symmetrically slidably connected within the mounting bracket;

[0010] The two arc-shaped grinding blocks can approach each other and press against the titanium alloy tube. When the two arc-shaped grinding blocks press against the titanium alloy tube, the axis of the titanium alloy tube is located in the middle between the two arc-shaped grinding blocks.

[0011] Furthermore, a slide block is slidably connected to the mounting base, a slide frame is slidably connected to the slide block, and the mounting frame is connected to the slide frame;

[0012] The sliding direction of the slide block is perpendicular to the sliding direction of the slide frame.

[0013] Furthermore, a limiting block is connected to the lower part of the sliding frame, and the limiting block can slide vertically and abut against the sliding base;

[0014] When the arc-shaped grinding block presses against the titanium alloy tube and the axis of the titanium alloy tube is in the middle between the arc-shaped grinding blocks, the limiting block slides down and abuts against the slide block to lock the sliding frame and the slide block.

[0015] Furthermore, the clamping mechanism includes a locking bracket that slides on the mounting base;

[0016] A rotating base is connected to the locking frame, and an installation cylinder is rotatably connected to the middle of the rotating base. The titanium alloy tube is inserted into the installation cylinder.

[0017] The mounting cylinder has three or more nuts threaded onto it. Tightening the nuts can lock the titanium alloy tube into the mounting cylinder.

[0018] Furthermore, the number of the locking brackets is two, and both locking brackets slide on the mounting base;

[0019] When the grinding mechanism is located between the two locking frames, it can grind the middle part of the titanium alloy tube;

[0020] When the grinding mechanism is located on the sides of the two locking frames, it can grind the ends of the titanium alloy tube.

[0021] Furthermore, the mounting bracket is equipped with a coating mechanism;

[0022] The coating mechanism includes a brush dipped in an oxidation protective coating.

[0023] When the coating brush moves upward and contacts the outer wall of the titanium alloy tube, and the titanium alloy tube rotates relative to the coating brush, the oxide protective coating can be applied to the titanium alloy tube.

[0024] Furthermore, the coating mechanism also includes a paint box, and the application brush slides vertically within the paint box.

[0025] Furthermore, the bottom of the paint box is connected to an electric telescopic rod, which extends and retracts synchronously with the up-and-down movement of the lower arc-shaped grinding block.

[0026] Furthermore, two connecting seats are symmetrically slidably connected inside the paint box, and each of the two connecting seats is rotatably connected to an extrusion roller, which is in contact with the application brush;

[0027] Two wedges are symmetrically connected to the mounting bracket, and the two wedges are respectively connected to the two connecting seats;

[0028] The connecting seats move closer to each other as they move upward along the corresponding two wedges;

[0029] The connecting seats move away from each other as they move down along the two corresponding wedges;

[0030] When the applicator brush moves, both of the extrusion rollers rotate, and the rotation tangent direction of the two extrusion rollers is consistent with the moving direction of the applicator brush.

[0031] Furthermore, the mounting bracket has a through hole and a spiral rod is connected inside the through hole. A protrusion is also provided inside the through hole of the mounting bracket. The protrusion slides in the groove of the side wall of the spiral rod, so that the spiral rod can rotate relative to the mounting bracket when it slides inside the through hole of the mounting bracket.

[0032] A stirring plate is connected inside the paint box, and the stirring plate is magnetically attracted to the top of the screw rod;

[0033] When the screw rotates, it can drive the stirring plate to rotate synchronously.

[0034] The beneficial effects of this invention are analyzed as follows:

[0035] A device for removing oxide layer from titanium alloy tubes includes a mounting base; the upper surface of the mounting base is provided with a clamping mechanism for holding the titanium alloy tube and a grinding mechanism for grinding the titanium alloy tube, the titanium alloy tube being rotatable relative to the grinding mechanism; the grinding mechanism includes a mounting frame that slides perpendicular to the titanium alloy tube, and two arc-shaped grinding blocks are symmetrically slidably connected within the mounting frame; the two arc-shaped grinding blocks can approach each other and press against the titanium alloy tube, and when the two arc-shaped grinding blocks press against the titanium alloy tube, the axis of the titanium alloy tube is located in the middle between the two arc-shaped grinding blocks.

[0036] Place the mounting base on a flat surface, and install the titanium alloy tube whose oxide layer needs to be removed onto the clamping mechanism. After moving the grinding mechanism to contact the titanium alloy tube, control the titanium alloy tube to rotate axially relative to the grinding mechanism, thereby mechanically grinding away the oxide layer on the surface of the titanium alloy tube. Two N-shaped brackets are connected to the mounting frame, and two cylinders are connected to the two N-shaped brackets. Move the mounting frame to the vicinity of the titanium alloy tube, and control the two cylinders to extend synchronously by the same length. At this time, the arc-shaped grinding blocks at the ends of the two cylinders approach each other. The titanium alloy tube fits with the inner wall of the arc-shaped grinding blocks. When the two arc-shaped grinding blocks approach each other, they can slide relative to each other along the outer wall of the titanium alloy tube, thereby allowing the arc-shaped grinding blocks to move radially along the titanium alloy tube. As the two arc-shaped grinding blocks continue to approach each other, the axis of the titanium alloy tube is eventually located in the middle of the two arc-shaped grinding blocks, thus ensuring that the titanium alloy tube is evenly ground by the arc-shaped grinding blocks when rotating, avoiding unevenness on the surface of the titanium alloy tube after grinding.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

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 can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0050] like Figures 1-7 As shown, a titanium alloy tube oxide layer removal device includes a mounting base 1; the upper surface of the mounting base 1 is provided with a clamping mechanism for clamping the titanium alloy tube and a grinding mechanism for grinding the titanium alloy tube, the titanium alloy tube can rotate relative to the grinding mechanism; the grinding mechanism includes a mounting frame 26 that slides perpendicular to the titanium alloy tube, and two arc-shaped grinding blocks 23 are symmetrically slidably connected inside the mounting frame 26; the two arc-shaped grinding blocks 23 can approach each other and press against the titanium alloy tube, and when the two arc-shaped grinding blocks 23 press against the titanium alloy tube, the axis of the titanium alloy tube is located in the middle between the two arc-shaped grinding blocks 23.

[0051] The working mechanism of the titanium alloy tube oxide layer removal device provided in this embodiment is as follows:

[0052] Place the mounting base 1 on a flat surface. Install the titanium alloy tube whose oxide layer needs to be removed onto the clamping mechanism. After moving the grinding mechanism to contact the titanium alloy tube, control the titanium alloy tube to rotate axially relative to the grinding mechanism, thereby mechanically removing the oxide layer on the surface of the titanium alloy tube. Two N-shaped brackets 24 are connected to the mounting frame 26, and two cylinders 22 are connected to the two N-shaped brackets 24. Move the mounting frame 26 to the vicinity of the titanium alloy tube and control the two cylinders 22 to extend synchronously by the same length. At this time, the arc-shaped grinding blocks 23 at the ends of the two cylinders 22 are... As the two arc-shaped grinding blocks 23 approach each other, they slide relative to each other along the outer wall of the titanium alloy tube, allowing the arc-shaped grinding blocks 23 to move radially along the titanium alloy tube. As the two arc-shaped grinding blocks 23 continue to approach each other, the axis of the titanium alloy tube is eventually located in the center of the two arc-shaped grinding blocks 23, thus ensuring that the titanium alloy tube is evenly ground by the arc-shaped grinding blocks 23 when rotating, and avoiding unevenness on the surface of the titanium alloy tube after grinding.

[0053] In addition, a pressure sensor is installed on the cylinder 22 in this embodiment, which can capture the pressure between the arc-shaped grinding block 23 and the titanium alloy tube, and can set the pressure to control the extension stroke of the cylinder 22, thereby controlling the grinding intensity.

[0054] Among the optional methods in this embodiment, the more preferred one is:

[0055] A slide block 21 is slidably connected to the mounting base 1, and a slide frame 2 is slidably connected to the slide block 21. The mounting frame 26 is connected to the slide frame 2. The sliding direction of the slide block 21 is perpendicular to the sliding direction of the slide frame 2.

[0056] When the slide block 21 slides on the mounting base 1, it can drive the grinding mechanism to move along the axial direction of the titanium alloy tube. When the sliding frame 2 slides relative to the slide block 21, it can adjust the radial relative position between the grinding mechanism and the titanium alloy tube.

[0057] Regarding how to lock the relative positions of the sliding bracket 2 and the slide block 21, specifically:

[0058] The lower part of the sliding frame 2 is connected to a limiting block 25, which can slide vertically and abut against the slide base 21. When the arc-shaped grinding block 23 presses the titanium alloy tube and makes the axis of the titanium alloy tube in the middle between the arc-shaped grinding blocks 23, the limiting block 25 slides down and abuts against the slide base 21 to lock the sliding frame 2 and the slide base 21.

[0059] By adjusting the parameters of the pressure sensor on the cylinder 22, the titanium alloy tube is positioned at the center of the two arc-shaped grinding blocks 23. After the two arc-shaped grinding blocks 23 apply appropriate pressure to the titanium alloy tube, the limiting block 25 extends after receiving the signal that the cylinder 22 has stopped running. As a result, the limiting block 25 slides down and abuts against the slide block 21. At this time, the sliding frame 2 and the slide block 21 no longer move relative to each other, thus ensuring that the arc-shaped grinding blocks 23 can be positioned at the required grinding position of the titanium alloy tube and no longer move.

[0060] Regarding the structure of the clamping mechanism, specifically:

[0061] The clamping mechanism includes a locking frame 11 that slides on the mounting base 1; a rotating seat 12 is connected to the locking frame 11, and a mounting cylinder 13 is rotatably connected to the middle of the rotating seat 12, into which the titanium alloy tube is inserted; three or more nuts 14 are threaded onto the mounting cylinder 13, and tightening the nuts 14 can lock the titanium alloy tube into the mounting cylinder 13.

[0062] When installing the titanium alloy tube, insert the titanium alloy tube into the middle of the mounting cylinder 13, and then tighten the nuts 14. At least three nuts 14 are provided, and the three or more nuts 14 are evenly distributed on the mounting cylinder 13 in a circle. This allows multiple nuts 14 to be tightened simultaneously, so that multiple nuts 14 move the same distance towards the mounting cylinder 13. This ensures that the titanium alloy tube is in the axial position of the mounting cylinder 13, and that the mounting cylinder 13 can drive the titanium alloy tube to rotate coaxially.

[0063] Among the optional methods in this embodiment, the more preferred one is:

[0064] There are two locking brackets 11, and both locking brackets 11 slide on the mounting base 1; when the grinding mechanism is located between the two locking brackets 11, it can grind the middle part of the titanium alloy tube; when the grinding mechanism is located on the side of the two locking brackets 11, it can grind the end of the titanium alloy tube.

[0065] When the middle part of the titanium alloy tube needs to be ground, the titanium alloy tube is clamped by a clamping mechanism, so that the grinding mechanism is between the two locking frames 11 of the clamping mechanism. This allows the middle part of the titanium alloy tube to be ground. When the end of the titanium alloy tube needs to be ground, the titanium alloy tube is connected to the two locking frames 11 of the grinding mechanism. The grinding mechanism is moved to one end of the titanium alloy tube to be ground. At this time, the grinding mechanism is located outside the two locking frames 11, so that the two locking frames 11 can provide sufficient support for the titanium alloy tube and ensure uniform grinding.

[0066] Regarding the structure of the coating mechanism, specifically:

[0067] The mounting bracket 26 is equipped with a coating mechanism; the coating mechanism includes a brush 32, which is dipped in an oxide protective coating; when the brush 32 moves upward and contacts the outer wall of the titanium alloy tube and the titanium alloy tube rotates relative to the brush 32, the oxide protective coating can be applied to the titanium alloy tube.

[0068] The mounting bracket 26 is also equipped with a vision sensor. The vision sensor detects the polished part of the titanium alloy tube. When it detects that the polished part has a metallic luster and a smooth surface, the slide block 21 drives the polishing mechanism to move. At this time, the clamping force of the two cylinders 22 on the arc-shaped polishing block 23 on the titanium alloy tube is canceled, so that the sliding of the slide block 21 is not subject to great resistance, thereby ensuring the relative movement between the mounting bracket 26 and the titanium alloy tube.

[0069] The sliding distance of the slide block 21 is just enough to make the arc-shaped grinding block 23 move away from the grinding position by a small distance. At this time, the brush 32 is directly below the grinding position of the titanium alloy tube. Thus, after the brush 32 moves up, it can contact the grinding position of the titanium alloy tube. At this time, the titanium alloy tube continues to rotate, which allows the brush 32 to apply the oxide protective coating to the titanium alloy tube, so that the grinding position of the titanium alloy tube is protected by the oxide protective layer, preventing the formation of an oxide layer on the titanium alloy tube before welding or other processes that require further processing.

[0070] Among the optional methods in this embodiment, the more preferred one is:

[0071] The coating mechanism also includes a paint box 3, and an application brush 32 slides vertically within the paint box 3.

[0072] An oxidation protective coating is placed inside the coating box 3. When the brush 32 slides down into the coating box 3, it can be immersed in the oxidation coating, so that the coating can be adhered to the brush 32 and an oxidation protective coating can be applied to the titanium alloy tube.

[0073] Among the optional methods in this embodiment, the more preferred one is:

[0074] The bottom of the paint box 3 is connected to an electric telescopic rod 31, which extends and retracts synchronously with the up-and-down movement of the lower arc-shaped grinding block 23.

[0075] The electric telescopic rod 31 extends and retracts synchronously with the lower cylinder 22, thereby ensuring that the distance between the paint box 3 and the outer wall of the titanium alloy tube remains constant, so that the distance between the paint box 3 and the titanium alloy tube of any diameter is equal.

[0076] Among the optional methods in this embodiment, the more preferred one is:

[0077] Two symmetrical sliding connecting seats 33 are connected inside the paint box 3. Each connecting seat 33 is rotatably connected to a squeezing roller 34, which is in contact with the application brush 32. Two wedges 35 are symmetrically connected on the mounting bracket 26, and the two wedges 35 are respectively connected to the two connecting seats 33. When the connecting seats 33 move upward along the corresponding two wedges 35, they move closer to each other. When the connecting seats 33 move downward along the corresponding two wedges 35, they move further apart from each other. When the application brush 32 moves, both squeezing rollers 34 rotate, and the rotation tangent direction of the two squeezing rollers 34 is consistent with the movement direction of the application brush 32.

[0078] As the brush 32 moves upward, the two extrusion rollers 34 rotate synchronously in opposite directions. At this time, the two extrusion rollers 34 guide the brush 32 while squeezing out excess paint from the brush 32. In addition, the electric telescopic rod 31 extends and retracts synchronously with the cylinder 22, so the paint box 3 moves up and down synchronously with the cylinder 22 below. When the paint box 3 moves upward, it means that the diameter of the titanium alloy tube being polished is small, and less paint is needed. The upward movement of the paint box 3 causes the connecting seat 33 to move along the inclined surface of the wedge block 35. At this time, the two connecting seats 33 move closer to each other, which increases the degree of extrusion on the brush 32. At this time, the amount of paint adhering to the brush 32 is reduced, which is suitable for titanium alloy tubes with smaller diameters. Conversely, the distance between the two extrusion rollers 34 increases, which allows more paint to be retained on the brush 32, which is suitable for titanium alloy tubes with larger diameters. This ensures that the thickness of the oxide protective coating applied to titanium alloy tubes of both large and small diameters is uniform, which is convenient for subsequent processing and can also save paint application.

[0079] In addition, to ensure the uniformity of the coating thickness on the surface of the titanium alloy tube, after the coating brush 32 contacts the outer wall of the titanium alloy tube, as the titanium alloy tube rotates, the coating brush 32 continues to move closer to the titanium alloy tube, thereby ensuring that more of the coating on the coating brush 32 can be applied to the titanium alloy tube, rather than just the top coating of the coating brush 32 being applied to the titanium alloy tube.

[0080] Among the optional methods in this embodiment, the more preferred one is:

[0081] The mounting bracket 26 has a through hole and a spiral rod 4 is connected inside the through hole. A protrusion 41 is also provided inside the through hole of the mounting bracket 26. The protrusion 41 slides in the groove on the side wall of the spiral rod 4, so that the spiral rod 4 can rotate relative to the mounting bracket 26 when it slides in the through hole of the mounting bracket 26. A stirring plate 42 is connected inside the paint box 3. The stirring plate 42 is magnetically attracted to the top of the spiral rod 4. When the spiral rod 4 rotates, it can drive the stirring plate 42 to rotate synchronously.

[0082] During the extension and retraction of the electric telescopic rod 31, the spiral rod 4 can move synchronously with the paint box 3 due to the magnetic attraction between the stirring plate 42 and the spiral rod 4. As the spiral rod 4 moves, the protrusion 41 can slide in the spiral groove of the spiral rod 4, and the spiral rod 4 can rotate. The rotating spiral rod 4 can drive the stirring plate 42 to rotate synchronously. The stirring plate 42 is set inside the paint box 3, so when the stirring plate 42 rotates, it can stir the paint in the paint box 3, so that the paint in the paint box 3 is mixed evenly, ensuring its oxidation protection effect.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
