Description

Technical Field

[0001] The present invention relates to the field of titanium alloy flaw detection, and particularly to an auxiliary flaw detection device for titanium alloy forgings. Background Art

[0002] Titanium alloy is an alloy formed based on titanium by adding other metal elements. Titanium alloy has characteristics such as high strength, good corrosion resistance, high heat resistance and low thermal conductivity, and is widely used in fields such as aerospace, medical, chemical industry, sports goods, automotive industry and shipbuilding. During the production and processing of titanium alloy, flaw detection of titanium alloy forgings is required.

[0003] In the patent with the publication number CN118777427B, an auxiliary flaw detection device for titanium alloy forgings is disclosed, which relates to the technical field of titanium alloy forging flaw detection, including a base. An installation plate is fixedly connected to the upper end of the base, and an ultrasonic detection head is installed on the upper end of the installation plate through a bracket.

[0004] However, the above flaw detection device still has certain defects when in use. In the prior art, in order to ensure the accuracy of flaw detection, it is usually necessary to ensure that the surface of the titanium alloy is smooth. Therefore, the titanium alloy needs to be surface-treated before flaw detection can be carried out, so the efficiency cannot be guaranteed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By the forward and reverse rotation of the motor in the present invention, during the process of the installation box body moving from the first support plate towards the fixed column, the simultaneous grinding work on the inner wall and the outer wall of the forging pipe is realized, which is beneficial to avoiding the situation that impurities exist on the side wall of the forging pipe and thus affecting the accuracy of flaw detection.

[0018] 2. By utilizing the magnetic force of the two second electromagnets in the present invention, the two installation box bodies move towards each other, so that the two installation box bodies are respectively abutted against the inner wall and the outer wall of the forging pipe. At the same time, by utilizing the magnetic force of the second electromagnet, the clamping force of the installation box body on the forging pipe can be effectively improved. When the grinding work on the inner wall and the outer wall of the forging pipe is carried out simultaneously, the grinding efficiency can be improved by increasing the pressure.

[0019] 3. In the present invention, through the pressure sensor arranged inside the L-shaped plate, during the return process of the installation box body, the attraction force between the installation box bodies remains in a stable state. During the return journey, the forces it receives are the magnetic force applied between the two second electromagnets, as well as the rolling force and frictional force between the limiting wheels and the forging pipe. Therefore, the force received by the pressure sensor should be in a stable state, and the fluctuation of the force is within a certain range. When detecting the flaw detection of some titanium alloy forging pipes that do not contain ferromagnetic metals such as iron and nickel, the real-time pressure fluctuation of the pressure sensor can also be used to determine whether impurity metals are mixed in the forging pipe. When a ferromagnetic metal is mixed in the forging pipe, the second electromagnet will attract the ferromagnetic metal, thereby causing a change in the pressure of the pressure sensor. When detecting the flaw detection of some titanium alloy forging pipes that contain ferromagnetic metals such as iron and nickel, it is also possible to judge whether the distribution of the ferromagnetic metal in the forging pipe is uniform through the pressure of the pressure sensor.

[0038] In specific implementation, the fixing rod 13 is used to maintain the horizontal of the lead screw 11.

[0039] As a further implementation scheme of the present invention, a first support plate 9 is fixedly connected to one side of the top of the workbench 1. A U-shaped rod 8 is slidably connected to the first support plate 9. The cross-section of the U-shaped rod 8 is rectangular. The two ports of the U-shaped rod 8 are respectively connected to two mounting boxes 7. A connecting driving rod 35 is fixedly connected to one end of the U-shaped rod 8 far from the mounting box 7.

The rotating block is rotatably sleeved in a rotating groove 36. A connecting disc 12 is fixedly connected to one end of the lead screw 11 far from the abutting component. The rotating groove 36 is opened on the connecting disc 12. The abutting component and the connecting disc 12 are respectively located on both sides of the second support plate 10.

[0040] In specific implementation, for each rotation of the lead screw 11, the advancing or retreating distance of the lead screw 11 is the same as the length of the friction block 31.

[0041] There are two first support plates 9 in total, which are used to maintain the horizontal of the U-shaped rod 8.

[0042] As another embodiment of the present invention, by adding lifting bases at the bottoms of the first support plate 9, the second support plate 10 and the bracket 14, the height of the lead screw 11 and the mounting box 7 can be adjusted, which is beneficial to adjusting the axis of the device, and thus the flaw detection of forging pipes 2 with different diameters can be carried out.

[0043] As a further implementation scheme of the present invention, L-shaped plates 24 are fixedly connected to the top and both sides of the bottom of the two mounting boxes 7 close to each other. A limiting wheel 25 is rotatably installed on one side of the two L-shaped plates 24 on the same side of the mounting box 7 opposite to each other. The limiting wheel 25 abuts against the wall plate of the forging pipe 2, and a pressure sensor is arranged inside the L-shaped plate 24.

[0044] In specific implementation, through the arrangement of the limiting wheel 25, during the rotation of the forging pipe 2, the limiting wheel 25 will also rotate accordingly. A gauze is arranged on the surface of the limiting wheel 25, and the gauze can wipe the dust on the forging pipe 2.

[0045] As a further embodiment of the present invention, horizontal grooves are respectively formed at the top and bottom of the installation box body 7 close to one side of the forging pipe 2. A first slider 26 and a second slider 28 are respectively slidably connected in the two horizontal grooves. The first slider 26 is located above the second slider 28. A vertical groove is formed at the center of the installation box body 7. A gear 29 is rotatably connected in the vertical groove. Rack teeth are provided on the sides of the first slider 26 and the second slider 28 close to each other.

The second electromagnets 30 on the two installation box bodies 7 interact with each other by magnetic force.

[0048] In specific implementation, during the movement of the installation box body 7, the two second electromagnets 30 attract each other by magnetic force. During the movement of the installation box body 7 from the first support plate 9 towards the fixed column 16, the first electromagnet 27 and the second electromagnet 30 inside the same installation box body 7 attract each other by magnetic force. During the movement of the installation box body 7 from the fixed column 16 towards the first support plate 9, the first electromagnet 27 and the second electromagnet 30 inside the same installation box body 7 repel each other by magnetic force.

The output end of the blower 22 is communicated with an air outlet inclined groove 23. The air outlet inclined groove 23 penetrates through the side wall plate of the through groove. The air outlet inclined groove 23 faces the inner bottom wall plate of the forging pipe 2. A contact switch 21 is fixedly connected to the center of the cross 15. A fixed column 16 is fixedly connected to the top of one end of the workbench 1 away from the bracket 14. The fixed column 16 is movably abutted against the contact switch 21. The contact switch 21 is communicatively connected to the motor 3, the first electromagnet 27 and the blower 22.

[0054] In specific implementation, an air inlet is opened at the bottom of the workbench 1, and the air inlet is communicated with the input end of the blower 22.

[0055] The working principle of the present invention:

[0056] When the present invention is in use, first, the forging pipe 2 forged from titanium alloy is placed in the through groove, so that the two roller shafts 6 support the forging pipe 2. Then the abutting assembly is moved to one end of the forging pipe 2 close to the bracket 14. At this time, by controlling the four electric sliders 18 to slide outwards simultaneously, the electric sliders 18 drive the connecting block 19 to move towards the inner wall of the forging pipe 2 through the connecting sliding column 20. As the connecting block 19 moves, the abutting wheel 17 will abut against the inner wall of the forging pipe 2. At this time, the forging pipe 2 can be stably placed through the abutting assembly and the roller shafts 6.

[0057] After the forging pipe 2 is placed, by starting the motor 3, the motor 3 drives the roller shafts 6 to rotate through the belt 4 and the transmission wheel 5. After the roller shafts 6 rotate, they will drive the forging pipe 2 to rotate. When the forging pipe 2 rotates, due to the frictional force exerted on the inner wall of the forging pipe 2 by the abutting wheel 17, the forging pipe 2 will drive the cross 15 to rotate through the abutting wheel 17. Through the rotation of the cross 15, the lead screw 11 will be driven to rotate. When the lead screw 11 rotates, it will perform screw rotation with the second support plate 10, thereby realizing the feeding of the lead screw 11. During the movement of the lead screw 11, the abutting wheel 17 will also roll as the lead screw 11 rotates. During this process, the abutting wheel 17 will roll on the inner wall of the forging pipe 2. Since the rotation axis of the abutting wheel 17 is skew perpendicular to the rotation axis of the forging pipe 2, during the rotation of the forging pipe 2, the cross 15 will be driven to rotate by the lateral frictional force on the wheel surface of the abutting wheel 17, and then the lead screw 11 will be driven to rotate through the rotation of the cross 15.

[0058] Meanwhile, during the movement of the lead screw 11, the rotation of the lead screw 11 drives the connection plate 12 to rotate. During the rotation of the connection plate 12, the rotating block at the end of the connection drive rod 35 rotates within the rotation groove 36. When the lead screw 11 moves, it drives the U-shaped rod 8 to move. The movement of the U-shaped rod 8 further drives the installation box body 7 to move. During the movement of the installation box body 7, the inner and outer walls of the forging pipe 2 can be simultaneously polished by the friction blocks 31. After the installation box body 7 moves to the end of the fixed column 16 on the workbench 1, the motor 3 is controlled to reverse. At this time, the flaw detection probe 32 inside the installation box body 7 can effectively perform flaw detection on the forging pipe 2.

[0059] Through the forward and reverse rotation of the motor 3, during the process of the installation box body 7 moving from the first support plate 9 towards the fixed column 16, the simultaneous polishing of the inner and outer walls of the forging pipe 2 is realized, which is beneficial to avoiding the situation that impurities on the side wall of the forging pipe 2 affect the flaw detection accuracy. During the process of the installation box body 7 moving from the fixed column 16 towards the first support plate 9, the flaw detection of the inner and outer walls of the forging pipe 2 can be effectively realized. Through one reciprocating movement of the installation box body 7, the polishing of the forging pipe 2 and the flaw detection of the inner and outer sides of the forging pipe 2 can be effectively realized, effectively ensuring the flaw detection accuracy of the titanium alloy forging pipe 2 and also improving the flaw detection efficiency.

[0060] During the process of the installation box body 7 moving from the first support plate 9 towards the fixed column 16, by controlling the magnetic poles of the second electromagnets 30 inside the two installation box bodies 7, the magnetic poles of the mutually approaching ends of the two second electromagnets 30 are set oppositely at this time. Using the magnetic force of the two second electromagnets 30, the two installation box bodies 7 move towards each other, so that the two installation box bodies 7 respectively abut against the inner and outer walls of the forging pipe 2. At the same time, using the magnetic force of the second electromagnets 30, the clamping force of the installation box body 7 on the forging pipe 2 can be effectively improved. When simultaneously polishing the inner and outer walls of the forging pipe 2, the polishing efficiency can be improved by increasing the pressure. During the process of the two installation box bodies 7 approaching each other, the limiting wheels 25 rotate effectively on the inner wall of the forging pipe 2.

[0061] During the process of the installation box body 7 moving from the first support plate 9 towards the fixed column 16, the magnetic poles of the mutually approaching ends of the first electromagnet 27 and the second electromagnet 30 located inside the same installation box body 7 are also arranged in opposite directions. At this time, by using the magnetic force between the first electromagnet 27 and the second electromagnet 30, the first electromagnet 27 moves towards the direction close to the second electromagnet 30. During this process, the first electromagnet 27 drives the first slider 26 towards the direction of the second electromagnet 30. When the first slider 26 moves, it drives the gear 29 to rotate through the rack at the bottom of the air, and the gear 29 makes the second slider 28 move away from the direction of the second electromagnet 30 through the rack at the top of the second slider 28, thereby realizing the storage of the flaw detection head 32, so that the flaw detection head 32 is stored in the installation box body 7, which is beneficial to avoiding the situation that dust adheres to the flaw detection head 32 during the process of grinding the forging pipe 2, thereby affecting the flaw detection accuracy.

[0062] During the process of grinding the forging pipe 2, the blower 22 is turned on, and the air blown out by the blower 22 through the air outlet chute 23 is used to blow out the dust ground from the inside of the forging pipe 2.

[0063] As the motor 3 rotates, when the contact switch 21 located on the cross 15 abuts against the fixed column 16, then the contact switch 21 controls the motor 3 to reverse, controls the first electromagnet 27 to change the magnetic pole, and controls the blower 22 to turn off.

[0064] After the motor 3 reverses, it drives the lead screw 11 to rotate in the reverse direction through the abutting component, thereby making the installation box body 7 move from the fixed column 16 towards the direction of the first support plate 9, and starting the return work of the installation box body 7.

[0065] After the first electromagnet 27 changes the magnetic pole, the first electromagnet 27 and the second electromagnet 30 will move away from each other through the repulsive force. At this time, the first electromagnet 27 drives the first slider 26 to move away from the forging pipe 2, and then makes the flaw detection head 32 move to the side of the forging pipe 2, and the forging pipe 2 is effectively detected through the flaw detection head 32.

[0066] Through the pressure sensor provided inside the L-shaped plate 24, during the return process of the mounting box body 7, the attraction force between the mounting box bodies 7 remains stable. During the return, the forces it receives are the magnetic force applied between the two second electromagnets 30, as well as the rolling force and frictional force between the limiting wheels 25 and the forging pipe 2. Therefore, the force received by the pressure sensor should be in a stable state, and the fluctuation of the force is within a certain range. When detecting the flaw detection of the titanium alloy forging pipe 2 that does not contain ferromagnetic metals such as iron and nickel, the real-time pressure fluctuation of the pressure sensor can also be used to determine whether impurity metals are mixed in the forging pipe 2. When a ferromagnetic metal is mixed in the forging pipe 2, the second electromagnet 30 will attract the ferromagnetic metal, which will in turn cause a pressure change in the pressure sensor. When detecting the flaw detection of the titanium alloy forging pipe 2 that contains ferromagnetic metals such as iron and nickel, it is also possible to judge whether the distribution of the ferromagnetic metal in the forging pipe 2 is uniform through the pressure of the pressure sensor.

[0067] Through the setting of the two second electromagnets 30, by changing the magnetic poles of the two second electromagnets 30, when the two second electromagnets 30 attract each other, relative sliding will occur between the two fixed box bodies 33 and the limiting sliders 34, and then the two mounting box bodies 7 will approach each other. When the two second electromagnets 30 repel each other, relative sliding will also occur between the two fixed box bodies 33 and the limiting sliders 34, and then the two mounting box bodies 7 will move away from each other.
