Detailed Description
In order that the above-described aspects may be better understood, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a test fixture for a high-pressure swing hose, which is shown in figures 1, 2,3 and 4 and comprises a support frame 1, a swing plate 2, a first rotating shaft 3, a second rotating shaft 4 and a third rotating shaft 5, wherein the swing plate 2 is arranged on the inner side of the support frame 1, the first rotating shaft 3, the second rotating shaft 4 and the third rotating shaft 5 are sequentially penetrated from top to bottom, two ends of the second rotating shaft 4 penetrate through the swing plate 2 and are rotationally connected with the support frame 1, a driving piece 6 is arranged on the side surface of the support frame 1 and is connected with the third rotating shaft 5 through a transmission rod 7, the third rotating shaft 5 is further driven, the third rotating shaft 5 drives the swing plate 2 to swing around the second rotating shaft 4, the transmission rod 7 is provided with a first end and a second end, the first end is sleeved on the third rotating shaft 5, the second end is connected with the output end of the driving piece 6, a first fixing component 8 is arranged on the end of the first rotating shaft 3, which extends out of the swing plate 2 and is connected with the end of the high-pressure swing hose, the second fixing component 9 is rotationally connected with the end of the high-pressure swing hose, the adjusting component 12 is connected with the inner side of the high-pressure swing hose far from the first fixing component 8, and the adjusting component 2 is arranged on the inner side of the first rotating shaft 2, the second rotating shaft 4 and the second rotating shaft 4 is further connected with the first rotating shaft 4 and the adjusting plate.
Illustratively, the lower end of the swing plate 2 is penetrated by the third rotating shaft 5, and the upper end of the swing plate 2 is penetrated by the first rotating shaft 3. I.e. in the vertical direction, the second shaft 4 is arranged between the first shaft 3 and the third shaft 5, and the support frame 1 is arranged at the end of the second shaft 4 extending to the outside of the wobble plate 2, i.e. the second shaft 4 can be moved up and down along the wobble plate 2 by means of the adjusting assembly 12.
The support frame 1 is symmetrically disposed below two ends of the second rotating shaft 4, and supports the second rotating shaft 4 to a horizontal position, when the horizontally disposed second rotating shaft 4 is used as a swinging fulcrum of the swinging plate 2, the swinging of the swinging plate 2 swings in a horizontal direction, so that the influence of the inclination to the swinging angle in the swinging process of the swinging plate 2 is avoided.
As shown in fig. 2, the first rotating shaft 3, the second rotating shaft 4 and the third rotating shaft 5 are long column-shaped rotating shafts, and further horizontally penetrate through two symmetrically arranged swinging plates 2. Wherein both ends of the upper first rotating shaft 3 are extended to the outside of the two swing plates 2, and a first fixing assembly 8 is provided at an end portion facing the high pressure swing hose. The two ends of the middle second rotating shaft 4 not only pass through the swinging plate 2, but also continue to extend outwards to pass through the supporting frame 1 outside the swinging plate 2, so that the second rotating shaft 4 becomes a fulcrum for swinging and rotating the swinging plate 2, and the swinging plate 2 swings and rotates around the second rotating shaft 4. The two ends of the third rotating shaft 5 below only penetrate through the swinging plate 2, and the length extending to the outer side of the swinging plate 2 cannot be too long, so that friction or collision between the two ends of the third rotating shaft 5 and the supporting frame 1 in the swinging and rotating process of the swinging plate 2 is avoided.
The driving element 6 may be a servo motor or an electric hydraulic cylinder, and the output end of the driving element 6 is connected to the third rotating shaft 5 through a transmission rod 7 to provide driving force.
Illustratively, the test fixture in this embodiment adjusts the distance between the second rotating shaft 4 and the first rotating shaft 3 and the third rotating shaft 5 on the wobble plate 2 through the adjusting assembly 12. I.e. the second axis of rotation 4 is closer to the third axis of rotation 5 and further from the first axis of rotation 3. In this case, even if the driving member 6 is selected to be smaller, the driving force provided is smaller, but because the second rotating shaft 4 is far from the first rotating shaft 3 above, when the swing plate 2 swings around the second rotating shaft 4 as a fulcrum, the swing arm between the first rotating shaft 3 and the second rotating shaft 4 directly connected with the high-pressure swing hose is longer, that is, a longer swing arm is provided for the high-pressure swing hose. By the arrangement, although the driving piece 6 is smaller in shape selection and smaller in output driving force, a larger swing angle can be provided, and further the requirement of the high-pressure swing hose on testing of the larger swing angle is met.
The second axis of rotation 4 is illustratively further from the third axis of rotation 5 and closer to the first axis of rotation 3. In this case, even if the driving member 6 is selected to be large, the driving force provided is large, and when the swing plate 2 swings around the second rotation shaft 4 as a fulcrum, a long output arm of force between the second rotation shaft 4 and the third rotation shaft 5 is connected to the driving member 6. Under the condition, the vibration propagation path of the driving piece 6 is longer, and the amplitude is gradually weakened along with the vibration propagation, namely, the propagation of the vibration generated by the driving piece 6 can be effectively reduced by a longer output force arm, the influence of the vibration of the driving piece 6 on the swing angle is reduced, the requirement of the high-pressure swing hose on the smaller swing angle can still be met, and the accuracy of the swing angle is improved.
In one possible embodiment, as shown in fig. 2, the number of wobble plates 2 is a plurality.
Illustratively, the number of wobble plates 2 of the present embodiment is 2. The 2 rocking plates 2 are arranged along the vertical direction, the first rotating shaft 3, the second rotating shaft 4 and the third rotating shaft 5 are arranged along the horizontal direction, and then the 2 rocking plates 2 and the first rotating shaft 3, the second rotating shaft 4 and the third rotating shaft 5 form a rectangular frame structure. The stability of frame construction is better, and more stable structure can make the propagation of vibration further reduce, and then has reduced driving piece 6 and produced the influence of vibration to the accuracy of rocking angle, further improves the accuracy of rocking angle. And the driving member 6 drives the third rotating shaft 5, so that the driving force can be more effectively transmitted to the high-pressure swing hose without being influenced by the vibration of the driving member 6 when the swing plate 2 is driven to swing around the second rotating shaft 4.
Illustratively, the number of the swinging plates 2 in the present embodiment is 3, since the vibration propagates from the driving member 6 to the high-pressure swinging hose along the swinging plates 2, the 3 swinging plates 2 further increase the propagation path of the vibration, and as the propagation path increases, the amplitude of the vibration decreases along with the propagation along the path, so that the 3 swinging plates 2 more effectively reduce the vibration generated by the driving member 6, further reduce the influence of the vibration of the driving member 6 on the swinging angle of the high-pressure swinging hose, and further improve the accuracy of the swinging angle.
In one possible embodiment, as shown in fig. 3 and 4, the adjusting assembly 12 includes an adjusting hole 121 formed in the swing plate 2 so that the second rotating shaft 4 passes through the adjusting hole 121, an adjusting plate 122 disposed inside the swing plate 2 and sleeved on the second rotating shaft 4 and connected to the swing plate 2 through an adjusting bolt 123, and an adjusting bolt 123 passing through the adjusting plate 122 and the swing plate 2 to adjust the position of the second rotating shaft 4 on the swing plate 2.
Illustratively, the adjusting component 12 is disposed between two symmetrically disposed swing plates 2, i.e., the inner walls of the swing plates 2, and after the driving member 6 is selected, the position of the second rotating shaft 4 on the swing plates 2 is adjusted by the adjusting component 12 according to the selected size of the driving member 6. The length of the opening of the adjusting hole 121 may be determined according to actual needs, and the adjusting hole 121 is formed in a vertical direction, from inside to outside, and two ends of the second rotating shaft 4 sequentially pass through the adjusting plate 122 and then pass through the swinging plate 2 through the adjusting hole 121. After the second rotating shaft 4 is adjusted to a required position, the position of the second rotating shaft 4 on the swing plate 2 is fixed through the adjusting bolt 123 and the swing plate 2, so that the lengths of the output force arm and the swing force arm are changed.
Illustratively, the adjusting plate 122 is disposed on the inner sidewall of the swinging plate 2, and bolt holes are formed on the swinging plate 2 and the adjusting plate 122, so that the adjusting plate 122 is used for adjusting and fixing the position of the adjusting plate 122 on the swinging plate 2, and the adjusting plate 122 is sleeved outside the second rotating shaft 4, so that the position of the second rotating shaft 4 on the swinging plate 2 can be adjusted by adjusting the adjusting plate 122, and the distance between the second rotating shaft 4 and the first rotating shaft 3 and the third rotating shaft 5 is changed.
In one possible embodiment, as shown in fig. 3, the sliding block 13 is disposed between the transmission rod 7 and the driving member 6 and is rotationally connected with both the transmission rod 7 and the driving member 6, and the sliding rail 14 is horizontally disposed below the sliding block 13, so that the sliding block 13 slides along the sliding rail 14 in a horizontal direction.
By way of example, since the transmission rod 7 is fitted over the third rotation shaft 5, i.e. over the third rotation shaft 5 between the two wobble plates 2. Under the condition that the opening driving piece 6 provides driving force, the driving rod 7 is driven to move, and the driving rod 7 drives the third rotating shaft 5 to move, so that the third rotating shaft 5 drives the swinging plate 2 to swing around the second rotating shaft 4. In this case, since the second rotating shaft 4 is a fulcrum of the swinging rotation of the swinging plate 2, the track of the third rotating shaft 5 driving the swinging plate 2 to swing and rotate is an arc line, and in the process of rotating the third rotating shaft 5, a certain amplitude of height change occurs in the third rotating shaft 5, that is, the third rotating shaft 5 drives the swinging plate 2 to swing and rotate until the swinging plate 2 is perpendicular to the ground, and the third rotating shaft 5 is at the lowest point of height. Correspondingly, the transmission rod 7 also changes in height during transmission, so that the transmission rod 7 does not always move in the horizontal direction. According to the embodiment, the sliding block 13 is arranged between the transmission rod 7 and the driving piece 6, so that the sliding block 13 only moves in the horizontal direction along the sliding rail 14, the output end of the driving piece 6 is guaranteed to move in the horizontal direction all the time, and the output end of the driving piece 6 is prevented from being damaged due to the influence of the height change in the movement process of the transmission rod 7. This arrangement ensures that the output end of the driving member 6 is only moved in a horizontal direction, avoiding damage to the driving member 6. In the process of providing driving force for the driving piece 6, as the two ends of the transmission rod 7 are rotationally connected, when the first end of the transmission rod 7 connected with the third rotating shaft 5 rotates to the lowest point, the second end of the transmission rod 7 connected with the sliding block 13 rotates to the highest point, so that the influence of the height change of the third rotating shaft 5 on the output end of the driving piece 6 is eliminated.
In one possible embodiment, as shown in fig. 1 and 2, the first fixing assembly 8 includes a first fixing member 81 disposed at an end of the second rotating shaft 4 near the high pressure swing hose, and a fixing flange 82 disposed below the first fixing member 81 and connected to an upwardly facing end of the high pressure swing hose.
Illustratively, welding is performed between the first fixing member 81 and the fixing flange 82, the fixing flange 82 is fixedly connected with the high-pressure swing hose through bolts, and sealing is performed between the fixing flange 82 and the high-pressure swing hose through placing a tetrafluoro gasket, so that the sealing requirement for the high-pressure swing hose is met, and the high-pressure requirement of the swing angle test is achieved.
In one possible embodiment, as shown in fig. 1 and 2, the second fixing assembly 9 includes a second fixing member 91 disposed at an end of the high pressure swing hose remote from the first fixing member 81, and a lifting assembly 92 disposed below the second fixing member 91 and connected to the second fixing member 91.
Illustratively, the lifting assembly 92 is welded to the second fixing member 91, so that the connection strength between the second fixing member 91 and the lifting assembly 92 is ensured. In the case that the high-pressure swing hose to be tested is L-shaped, as shown in fig. 1 and 2, i.e., the first fixing member 81 is above the high-pressure swing hose and is correspondingly connected with the vertical section high-pressure swing hose, the second fixing member 91 is horizontally arranged and is correspondingly connected with the horizontal section high-pressure swing hose, so that the fixed connection of the L-shaped high-pressure swing hose in the swing angle test is satisfied. And, in this case, the swing hose is fixedly connected to the second fixing member 91 due to the high pressure of the horizontal section. Therefore, when the swing angle test is carried out on the high-pressure swing hose of the vertical section, the torsion test is carried out on the high-pressure swing hose of the horizontal section, and the test process of the synchronous carrying out of the swing angle test of the vertical section and the torsion test of the horizontal section is the same as the actual use situation of the high-pressure swing hose in the rocket propeller.
Illustratively, in the case where the high-pressure swing hose to be tested is a straight pipe, the second fixing member 91 is disposed directly under the first fixing member 81 in the vertical direction. That is, the first fixing member 81 is above the high-pressure swing hose, and the second fixing member 91 is below the high-pressure swing hose, so as to satisfy the fixed connection of the straight-tube-shaped high-pressure swing hose in the swing angle test.
In one possible embodiment, as shown in fig. 1 and 2, the second fixing assembly 9 further comprises an air injection cavity 10 disposed inside the second fixing member 91, and an air injection hole 11 disposed on a side surface of the second fixing member 91 away from the high-pressure swing hose and communicating with the air injection cavity 10 and an external air source.
By way of example, by providing the gas injection cavity 10 and the gas injection hole 11, and the second fixing member 91 is communicated with the high-pressure swing hose, the external gas source charges the high-pressure swing hose through the gas injection hole 11 and the gas injection cavity 10 in sequence, so that the high-pressure swing hose in the embodiment meets the requirement of high pressure in the testing process. Correspondingly, when the connection between the gas injection hole 11 and an external gas source is disconnected, the pressure relief of the high-pressure swing hose can be realized.
Illustratively, a valve may be disposed on the gas injection hole 11 and then connected to an external gas source through the valve, so that the pressurization and the pressure relief of the high-pressure swing hose are more convenient.
In one possible embodiment, as shown in fig. 1 and 2, the elevation assembly 92 includes an elevation column 921 disposed at a side of the second fixing member 91, a moving stage 922 disposed below the second fixing member 91 and connected to the elevation column 921, and an elevation driver 923 disposed at a side of the elevation column 921 and connected to the moving stage 922 to drive the moving stage 922 to move in a direction in which the elevation column 921 is disposed.
Illustratively, the movable platform 922 is fixedly connected to the second fixing member 91 by bolts, and the lifting driver 923 in this embodiment is a hydraulic cylinder, so as to drive the movable platform 922 to move up and down along the lifting column 921. The lifting column 921 in this embodiment is perpendicular to the ground, so the hydraulic cylinder drives the mobile station 922 to move up and down, so as to adjust the vertical distance between the first fixing member 81 and the second fixing member 91, so that the test fixture can fix the high-pressure swing hoses of different types, and the swing angle test requirements of the high-pressure swing hoses of different types can be realized.
In one possible embodiment, as shown in fig. 1 and 2, the translation drive 15 is disposed on the side of the mobile station 922 remote from the high pressure swing hose and is connected to the mobile station 922.
The slide way is disposed below the moving platform 922, the slide way is disposed towards the support frame 1, after the translational driving machine 15 is started, the translational driving machine 15 can drive the moving platform 922 to move along the horizontal direction close to the support frame 1 or move away from the support frame 1, so as to adjust the horizontal distance between the first fixing member 81 and the second fixing member 91, and further make the testing tool of the embodiment meet the swing angle testing requirements of high-pressure swing hoses of different models.
In one possible embodiment, as shown in fig. 1 and 3, the number of lifting columns 921 is multiple.
Illustratively, a plurality of lifting columns 921 may better improve the smoothness of the mobile station 922 during movement along the lifting columns 921. The number of the lifting columns 921 in this embodiment is 2. The 2 lifting columns 921 are provided at both sides of the second fixing member 91, respectively, and thus, when the moving stage 922 moves up or down along the lifting columns 921, the smoothness during the movement of the moving stage 922 is increased.
