Description

[0002] As one of the traditional detection methods in the nondestructive testing industry, ultrasonic immersion nondestructive testing technology is widely used in the fields of aerospace and others. Especially for some important parts such as titanium alloy forgings of aviation materials, the ultrasonic immersion detection system can evaluate the internal state of the workpiece by using ultrasonic imaging technology, so as to find internal defects in time and then process them in time to avoid greater losses. When detecting the parts by ultrasonic waves, the workers will place the parts on the rotary table, then use the clamping structure provided on the rotary table to fix the parts, immerse the rotary table and the parts in water, and then make the rotary table drive the parts to rotate, so that the ultrasonic detector emits ultrasonic waves to different surfaces of the parts, facilitating the workers to detect different positions inside the parts. The clamping structure of some existing rotary tables for ultrasonic immersion detection is fixed in position, and the workers cannot adjust the number and position of the clamping structure according to the shape of the parts, so that the clamping effect of the existing rotary table on some irregularly shaped parts is poor, which not only reduces the practicability of the rotary table, but also causes the parts to possibly separate from the clamping mechanism on the rotary table when the rotary table rotates while clamping these irregularly shaped parts, thereby hindering the detection work.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-6 As shown, a turntable for ultrasonic water immersion testing of titanium alloy forgings includes a worktable 1. The upper surface of the worktable 1 has a mounting hole 101. A reducer 3 is fixedly installed in the mounting hole 101. A motor 4 is fixedly installed on one side of the reducer 3.

[0039] The inner wall of the mounting hole 101 is fixedly installed with a sealing plate 102, the output end of the speed reducer 3 penetrates through the sealing plate 102 and is fixedly installed with a bearing table 5, the bearing table 5 is rotatably installed in the mounting hole 101 through a bearing, a first annular groove 501 is formed in the upper surface of the bearing table 5, a plurality of arc-shaped blocks 6 are movably arranged in the first annular groove 501, a connecting plate 7 is fixedly installed on each side of each arc-shaped block 6, a guide plate 8 is fixedly installed on the top of each two adjacent connecting plates 7, a guide groove 801 is formed in the upper surface of each guide plate 8, a clamping block 802 is slidably arranged in each guide groove 801, a threaded hole is formed in the upper surface of each clamping block 802, and a fastening bolt 803 is threadedly arranged in each threaded hole. The guide groove 801 is arranged to be narrow at the top and wide at the bottom, so as to limit the upward movement of the clamping block 802.

[0040] An installation groove 601 is formed in the upper surface of each arc-shaped block 6, and a limiting assembly 2 for limiting the movement of the arc-shaped block 6 is arranged in each installation groove 601.

[0041] Through the above technical scheme, when in use, the worker puts a corresponding number of arc-shaped blocks 6 into the first annular groove 501 after determining the shape of the part, then moves each arc-shaped block 6 to the corresponding clamping position along the direction of the first annular groove 501, then the worker uses the limiting assembly 2 to make the limiting assembly 2 tightly fit the inner wall of the first annular groove 501, so that the position of the arc-shaped block 6 is limited, thereby installing the arc-shaped block 6, the guide plate 8 and the clamping block 802 on the bearing table 5, then the worker pushes the clamping block 802 to make the clamping block 802 move along the guide groove 801, after the clamping end surface of the clamping block 802 tightly fits the surface of the part, the worker twists the fastening bolt 803 to make the clamping block 802 clamp the part, and under the cooperation of the first annular groove 501, the arc-shaped block 6 and the limiting assembly 2, the worker can quickly adjust the position and number of the clamping block 802 according to the shape of the part, so that the turntable can effectively clamp irregular parts, increase the practicability of the turntable, avoid the part from being separated from the turntable during rotation, and make the detection work smoothly.

[0042] As shown in Figure 1 , Figure 4 , Figure 7 , Figure 9 In this embodiment, the limiting assembly 2 comprises an installation plate 201, a lead screw 202 is rotatably installed on one side of the lower surface of the installation plate 201, a moving plate 203 is threadedly arranged on one side of the rod body of the lead screw 202, and a triangular plate 205 is fixedly installed on the upper surface of the moving plate 203 through a support 204.

[0043] The inner wall of the mounting groove 601 is fixedly installed with two horizontal plates 206, the lower surface of each horizontal plate 206 is provided with a sliding groove 207, the sliding groove 207 is slidably provided with a sliding block 208, the lower surface of the sliding block 208 is fixedly installed with a vertical plate 209, the vertical plate 209 is fixedly installed with two push plates 2010 close to one side of the triangular plate 205, the vertical plate 209 is fixedly installed with a top plate 2012 through a connecting frame 2011 away from the other side of the triangular plate 205, each top plate 2012 is a rubber plate, the top plate 2012 is arranged as a rubber plate, so that the top plate 2012 can be bent and more fully attached to the inner wall surface of the first annular groove 501 under the elastic effect of the rubber when the inner wall of the first annular groove 501 is touched, and the surface friction of the rubber is large, so that the clamping effect of the top plate 2012 is good, and the inner wall of the mounting groove 601 is provided with an avoiding groove 2013 at the position corresponding to the top plate 2012.

[0044] The inner wall of the sliding groove 207 is fixedly installed with a limiting rod 2014 between the two sides, and the sliding block 208 is slidably arranged on one side of the limiting rod 2014.

[0045] The lower surface of each mounting plate 201 is fixedly installed with a positioning rod 2015 on the other side, and the moving plate 203 is slidably arranged on one side of the positioning rod 2015. After the arc-shaped block 6 is placed in the first annular groove 501, the worker rotates the lead screw 202, the rotating lead screw 202 drives the moving plate 203 to drive the triangular plate 205 to move along the positioning rod 2015 through the threaded rotation, so that the inclined surface of the triangular plate 205 pushes the push plate 2010, so that the push plate 2010 and the vertical plate 209 and the sliding block 208 move along the sliding groove 207, so that the top plate 2012 moves along the sliding groove 207 and clamps the first annular groove 501, so that the position of the arc-shaped block 6 is limited, so that the worker installs the guide plate 8 and the clamping block 802 on the bearing table 5, when the worker needs to move or remove the guide plate 8 and the clamping block 802, the worker reversely rotates the lead screw 202, so that the top plate 2012 is separated from the inner wall of the first annular groove 501, which is very convenient and fast.

[0046] As Figure 1 , Figure 7 , Figure 9It is to be noted that each limiting rod 2014 is sleeved with a first spring 2016 on the side away from the corresponding sliding block 208. When the sliding block 208 moves along the sliding groove 207 and the top plate 2012 is tightly pressed against the inner wall of the first annular groove 501, the first spring 2016 is compressed under force. After the staff reversely rotates the lead screw 202, the triangular plate 205 moves upward, the first spring 2016 resets and pushes the sliding block 208 to move reversely, so that the top plate 2012 moves to the original position, and the staff does not need to manually reset the top plate 2012, thereby reducing the labor intensity of the staff.

[0047] Each two adjacent push plates 2010 are rotatably installed with a rotating roller 2018 through a rotating shaft 2017. The rotating shaft 2017 and the rotating roller 2018 change the sliding friction of the triangular plate 205 when pushing the push plate 2010 into rolling friction, reduce the friction of the triangular plate 205 when pushing the push plate 2010, thereby reducing the degree of wear of the surface of the triangular plate 205 and the push plate 2010 each time they move, and prolonging the service life of the push plate 2010 and the triangular plate 205.

[0048] The upper end of each lead screw 202 penetrates through the corresponding mounting plate 201 and is fixedly installed with a rotating wheel 2019. This facilitates the staff to rotate the lead screw 202.

[0049] As shown in Figure 6 , Figure 7 , Figure 9 When specifically setting, the lower surface of each moving plate 203 is fixedly installed with a pressing plate 2021 through a connecting rod 2020.

[0050] The inner wall upper surface of each mounting groove 601 is throughly provided with a through groove 2022.

[0051] The lower surface of each pressing plate 2021 is provided with a plurality of connecting holes 2023, each connecting hole 2023 is slidably provided with a pressing column 2024, and a second spring 2025 is fixedly installed between each connecting hole 2023 and the corresponding pressing column 2024. When the moving plate 203 moves downward, the pressing plate 2021 moves with the moving plate 203 and penetrates through the through groove 2022 and is tightly attached to the upper surface of the inner wall of the first annular groove 501. When the pressing plate 2021 is attached to the upper surface of the inner wall of the first annular groove 501, the second spring 2025 is compressed and gives the pressing column 2024 a reverse pushing force, so that the lower surface of the pressing column 2024 is tightly attached to the upper surface of the inner wall of the first annular groove 501, thereby making the arc-shaped block 6 more difficult to move and enhancing the limiting effect on the arc-shaped block 6.

[0052] As shown in Figure 1 , Figure 6 , Figure 8As shown, it can be understood that each arc-shaped block 6 is movably provided with a universal wheel 9 on the lower surface.

[0053] The inner wall of the first annular groove 501 is provided with a second annular groove 5011 on both sides.

[0054] Each arc-shaped block 6 is provided with a moving groove 602 on both sides, two moving blocks 603 are slidably arranged in each moving groove 602, a fixed block 604 is fixedly installed on the side away from the corresponding arc-shaped block 6 of each moving block 603, two fixed frames 605 are fixedly installed on the sides away from each other of each two adjacent fixed blocks 604, and a guide wheel 606 is rotatably installed between each two adjacent fixed frames 605 through a connecting shaft;

[0055] A cross rod 607 is fixedly installed between the inner walls of each moving groove 602, each two adjacent moving blocks 603 are slidably arranged on both sides of the corresponding cross rod 607, and a third spring 608 is sleeved on the middle part of each cross rod 607. By arranging the guide wheel 606, the sliding friction between the lower surface of the arc-shaped block 6 and the lower surface of the first annular groove 501 is converted into rolling friction when the arc-shaped block 6 is moved, thereby greatly reducing the wear between the lower surface of the arc-shaped block 6 and the upper surface of the inner wall of the first annular groove 501. By arranging the second annular groove 5011 and the guide wheel 606, the sliding friction between the side wall surface of the arc-shaped block 6 and the inner wall of the first annular groove 501 is converted into rolling friction, thereby greatly reducing the wear between the side wall surface of the arc-shaped block 6 and the surface of the inner wall of the first annular groove 501. By arranging the moving block 603, the moving groove 602 and the third spring 608, the installation and disassembly between the guide wheel 606 and the second annular groove 5011 are facilitated.

[0056] In specific arrangement, the lower surface of the inner wall of each moving groove 602 is provided with a supporting groove 6021, the upper surface of each moving block 603 is fixedly installed with a push block 6031, and the upper surface of each push block 6031 extends to the outside of the supporting groove 6021. By arranging the supporting groove 6021 and the push block 6031, the moving block 603 is facilitated to move.

[0057] The working principle of the rotary table for ultrasonic water immersion detection of titanium alloy forgings is as follows:

[0058] When in use, firstly, the staff places the corresponding number of arc-shaped blocks 6 into the first annular groove 501 according to the shape of the part, then moves each arc-shaped block 6 to the corresponding clamping position along the first annular groove 501, then the staff makes the limiting assembly 2 closely contact with the inner wall of the first annular groove 501 by using the limiting assembly 2, so that the position of the arc-shaped block 6 is limited, thereby installing the arc-shaped block 6, the guide plate 8 and the clamping block 802 on the bearing table 5, then the staff pushes the clamping block 802, so that the clamping block 802 moves along the guide groove 801, after the clamping end surface of the clamping block 802 closely contacts with the surface of the part, the staff twists the fastening bolt 803, so that the clamping block 802 clamps the part, under the cooperation of the first annular groove 501, the arc-shaped block 6 and the limiting assembly 2, the staff can quickly adjust the position and the number of the clamping block 802 according to the shape of the part, thereby the rotary table can effectively clamp the irregular part, the practicability of the rotary table is increased, the situation that the part is separated from the rotary table when the rotary table rotates is avoided, and the detection work can be smoothly carried out.
