[0001] The invention relates to the technical field of material surface heat treatment devices, and in particular to a titanium alloy workpiece surface strengthening treatment device. Background Art

[0002] Titanium alloy is a material with broad application prospects and excellent performance. The research on its surface strengthening treatment technology is of great significance for improving the mechanical properties and corrosion resistance of titanium alloy materials. Titanium alloy surface strengthening treatment can be divided into three categories, namely physical methods, chemical methods and composite modification methods. Nowadays, chemical methods are used to strengthen the surface of titanium alloys. The cladding technology is often used to coat the mixed graphene on the alloy surface, and the micro-nano-scale titanium carbide particles are generated in situ in the titanium alloy matrix after high temperature reaction. However, when the graphene mixture is clad on the alloy surface, firstly, the mixture is easy to fall off when cladding on the surface of the alloy with a large inclination angle, resulting in the titanium carbide particles not being evenly distributed in the titanium alloy matrix, affecting the surface strength of the titanium alloy.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Example, see Figures 1 to 7 A titanium alloy workpiece surface strengthening treatment device includes an isolation cover 1 connected to a robot arm through a redirection component. Furthermore, the redirection component includes a plurality of side universal ball shafts 24 and a center universal ball shaft 25 inserted into the inner wall of the outer convex edge and the inner wall of the top end of the isolation cover 1.

[0030] A further advantage of adopting the above method is that the isolation cover 1 can wrap the entire cladding assembly to prevent external gas from contacting the mixed material during cladding, resulting in insufficient reaction of the mixed material on the alloy surface, causing insufficient production of titanium carbide particles and affecting the surface treatment quality of the alloy. The side universal ball shaft 24 and the center universal ball shaft 25 can be connected to the robot arm in the prior art, and the height of the side universal ball shaft 24 can be changed by the extension and retraction of the robot arm to change the direction of the isolation cover 1, thereby facilitating the device to clad the mixed material on the alloy surface with a larger inclination angle.

[0031] A device groove 2 is provided at the bottom of the isolation cover 1, and a reset component is provided on one side of the inner bottom wall of the device groove 2. Furthermore, the reset component includes a fixing seat 11 fixed to one side of the inner bottom wall of the device groove 2, and a feed drive plate 12 is plugged into the port of the fixing seat 11, and a reset spring 13 is fixed between the top of the feed drive plate 12 and the inner bottom wall of the fixing seat 11.

[0032] A further advantage of adopting the above method is that when the stepping wheel 3 rolls on the alloy surface, it will drive the convex edge plate on the side to rotate, so that the feeding drive plate 12 can be driven up and down by the convex edge plate on the outside of the stepping wheel 3. The convex edge plate is located at the center of the feeding drive plate 12, and the inclined surface on the side of the convex edge plate is adapted to the inclined surface on the side of the feeding drive plate 12. After that, the mixed material on the surface of the alloy can be clad in cooperation with the following interlocking gear plate 16 and pressing sleeve 17. The reset spring 13 can move the feeding drive plate 12 down to the lowest working position when the feeding drive plate 12 is located between the two convex edge plates on the side of the stepping wheel 3.

[0033] A stepping wheel 3 is provided at the bottom of the reset assembly, and a supporting shaft rod 4 is hinged inside the stepping wheel 3. Both ends of the supporting shaft rod 4 are hinged to the inner wall of the device groove 2. Contact grooves 5 are provided on the surfaces of several convex edges on the side of the stepping wheel 3, and enclosing plates 6 are fixed on both ends of the convex edges on the side of the stepping wheel 3. A connecting rod assembly is fixed on one side of the reset assembly. Furthermore, the connecting rod assembly includes a supporting connecting rod 14 fixed to one side of the feeding drive plate 12, and a circular hole is provided in the middle of the supporting connecting rod 14.

[0034] The further advantage of adopting the above method is that the supporting connecting rod 14 moves up and down through the above-mentioned feeding driving plate 12, driving the linkage gear plate 16 and the pressing sleeve 17 to move synchronously with the rotating outer cylinder 7 and the discharge vertical pipe 19, so that the mixed material can be discharged from the discharge vertical pipe 19 at a fixed distance and in a fixed quantity. In the process of the mixed material being released, the rotating outer cylinder 7 can be driven to rotate by the linkage gear plate 16, which provides favorable conditions for the upper porous cladding ring gun 8 and the final cladding hole 10 to evenly disperse the mixed material on the alloy surface.

[0035] A driving assembly is provided in the middle of the connecting rod assembly. Further, the driving assembly includes a driving motor 15 fixed to the inner wall of the circular hole in the middle of the supporting connecting rod 14, and a linkage gear plate 16 is fixed to the bottom of the driving motor 15. The side of the linkage gear plate 16 is connected to the outer side of the rotating outer cylinder 7 through a tooth groove.

[0036] A further advantage of adopting the above method is that the driving motor 15 can drive the rotating outer cylinder 7 to rotate slowly through the interlocking gear plate 16 when the feeding driving plate 12 descends, so as to evenly spread the mixed material on the alloy surface, thereby avoiding uneven dispersion of titanium carbide particles in the alloy matrix after cladding, which affects the quality of the alloy surface strengthening treatment.

[0037] A discharge assembly is provided at one end of the connecting rod assembly. Furthermore, the discharge assembly includes a pressing sleeve 17 fixed to one end of the supporting connecting rod 14, and the bottom of the convex edge on the outer side of the pressing sleeve 17 is tightly fitted to the upper surface of the upper porous cladding ring gun 8, a sealing plug 18 is fixed to the inner wall of the bottom end of the pressing sleeve 17, and a discharge vertical pipe 19 is inserted into the inner wall of the pressing sleeve 17.

[0038] A further advantage of adopting the above method is that after the pressing sleeve 17 is lowered, the sealing plug 18 can be driven to detach from the bottom of the discharge vertical pipe 19, so that the mixed material is discharged from the bottom of the discharge vertical pipe 19 into the spiral overflow prevention cover 23.

[0039] A feeding assembly is provided on the top of the discharge assembly. Further, the feeding assembly includes a feeding pipe 20 fixed to the top of the discharge vertical pipe 19, and one end of the pipe mouth of the feeding pipe 20 is inserted into the inner wall of the isolation cover 1.

[0040] A further advantage of adopting the above method is that the feeding pipe 20 is a prior art and will not be described in detail here. Its function is to discharge the externally mixed mixed material quantitatively from the discharge vertical pipe 19 to the inside of the spiral overflow prevention cover 23 through the feeding pipe 20.

[0041] The side of the driving component is meshedly connected with a rotating outer cylinder 7, and the outer side of the rotating outer cylinder 7 is connected to the device groove 2 through a supporting component. Furthermore, the supporting component includes a supporting frame 21 which is sleeved on the outer side of the rotating outer cylinder 7, and an air inlet hole is opened on the side of the supporting frame 21. One end of the air inlet hole is connected to the inner cavity of the rotating outer cylinder 7 through a through hole opened on the outer side of the rotating outer cylinder 7, and both ends of the supporting frame 21 are fixed to the inner wall of the device groove 2.

[0042] The further advantage of adopting the above method is that the support frame 21 can support the rotating outer cylinder 7 and can transport the external combustible gas to the inner cavity of the rotating outer cylinder 7 through the hole cavity, and then transport it to the upper porous cladding ring gun 8 and the final cladding hole 10, so as to further enable the upper porous cladding ring gun 8 and the final cladding hole 10 to spray out the mixture on the surface of the flame cladding alloy at the nozzle, and generate titanium carbide particles in the alloy matrix.

[0043] The bottom of the discharge component is tightly fitted with the upper porous cladding ring gun 8, and a cladding hose 9 is fixed on the top of the upper porous cladding ring gun 8. One end of the cladding hose 9 is fixed to one end of the connecting hole on the inner wall of the rotating outer cylinder 7. The bottom of the upper porous cladding ring gun 8 is inserted into the inner wall of the rotating outer cylinder 7 through an inclined groove. A plurality of terminal cladding holes 10 are opened at the bottom of the rotating outer cylinder 7. One end of the terminal cladding hole 10 is connected to the upper porous cladding ring gun 8 through the inner cavity of the rotating outer cylinder 7 and the cladding hose 9. An anti-overflow component is provided at the bottom of the discharge component. Furthermore, the anti-overflow component includes a heat-resistant ring 22 sleeved on the bottom of the pressing sleeve 17, and a spiral anti-overflow cover 23 is sleeved on the bottom of the heat-resistant ring 22.

[0044] The further advantage of adopting the above method is that the spiral overflow prevention cover 23 can store the mixture after discharging it at the bottom of the discharge vertical pipe 19, so as to prevent the mixture from escaping and affecting the cladding of the mixture by the upper porous cladding ring gun 8 and the last cladding hole 10. At the same time, the threaded ring groove opened on the side of the spiral overflow prevention cover 23 can also facilitate the upper porous cladding ring gun 8 and the last cladding hole 10 to heat the mixture. In addition, the bottom injection port of the upper porous cladding ring gun 8 is located at the same horizontal plane as the last cladding hole 10 when it is placed flat. When the angle of the isolation cover 1 changes and it works on the alloy surface with a larger inclination angle, the upper porous cladding ring gun 8 can rotate in the matching groove opened on the inner wall of the rotating outer cylinder 7 away from the last cladding hole 10 to form a height difference, so as to wrap the mixture and prevent the mixture from escaping or accumulating.

[0045] The present invention is as follows before use Figure 1As shown, the side universal ball shaft 24 is connected to the output end of the robot arm motor in the prior art through a wire groove, and it is intended to drive one or more side universal ball shafts 24 to move through the rotation of the motor output end to change the direction of the isolation cover 1, and the center universal ball shaft 25 is connected to the end of the robot arm;

[0046] The present invention is used as Figure 6 As shown, when the robot arm moves, the enclosing plate 6 can drive the stepping wheel 3 to roll on the alloy surface. During the rolling process of the stepping wheel 3, the feeding drive plate 12 will move to the bottom between two adjacent convex plates on the side of the stepping wheel 3 under the drive of the return spring 13. At this time, the pressing sleeve 17 can be driven downward by the supporting connecting rod 14, so that Figure 5 The sealing plug 18 shown in the figure is detached from the bottom of the discharge vertical pipe 19. At this time, the mixed material can be quantitatively discharged under the action of the feeding pipe 20 and slide into the inside of the spiral anti-overflow cover 23. At this time, the bottom of the spiral anti-overflow cover 23 is in contact with the alloy surface to prevent the mixed material from escaping. Secondly, the supporting connecting rod 14 can drive the linkage gear plate 16 to move down and mesh with the rotating outer cylinder 7, thereby driving the rotating outer cylinder 7 to rotate. During the rotation of the rotating outer cylinder 7, the internal upper porous cladding ring gun 8 will be driven to rotate. The upper porous cladding ring gun 8 and the last cladding hole 10 will spray high-temperature flames to melt the mixture in the spiral anti-overflow cover 23 during this process. First, the mixture can be heated through the threaded groove on the side of the spiral anti-overflow cover 23. Second, it can prevent the mixture from being dispersed by the flames sprayed by the upper porous cladding ring gun 8 and the last cladding hole 10 after falling, resulting in uneven distribution of titanium carbide particles after the melting reaction in the titanium alloy matrix, affecting the surface strengthening quality of the titanium alloy.

[0047] As the stepping wheel 3 continues to roll, the feeding drive plate 12 will move upward driven by the convex edge of the side of the stepping wheel 3, thereby driving the linked gear plate 16 and the pressing sleeve 17 to move upward. During the rolling process of the stepping wheel 3, as the rotating outer cylinder 7 rotates, the upper porous cladding ring gun 8 and the last cladding hole 10 will rotate. The impact of the flame spray will evenly disperse the mixed material on the surface of the alloy plate for cladding, thereby avoiding uneven distribution of titanium carbide particles after the reaction, which will affect the surface strengthening quality of the titanium alloy.

[0048] When the device melts the mixture on the alloy surface with a large inclination angle, when the rotating outer cylinder 7 is tilted upward, the upper porous cladding ring gun 8 will move to the side of the upper material pipe 20 and separate from the last cladding hole 10 due to its own gravity, so that the mixture can be wrapped by the impact of the flame to prevent the mixture from detaching from the alloy surface, thereby affecting the quality of the carbon alloy surface strengthening treatment.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
