Description

Technical Field

[0001] The present invention relates to the technical field of resonance rod manufacturing, and in particular to a strength detection device for resonance rod manufacturing. Background Art

[0002] The resonant rod is a necessary part used in aerospace, radio and television communication base station equipment. It is a key component of the cavity filter. The resonant rod and the closed metal cavity jointly generate the resonant frequency, thereby realizing the frequency selection function required by the filter. The resonant rod needs to have good conductivity, so it is usually made of aluminum, steel, copper or brass with silver plating on the surface. The resonant rod is mainly composed of two parts, a long rod and a long tube fixed together. The long rod is located at the end of the long tube, and the two are welded. The overall structure is simple. After the resonant rod is manufactured, the strength of the resonant rod needs to be tested. The resonant rod is placed on the workbench and a certain force is applied to the resonant rod through hydraulic equipment. After a period of time, observe whether the resonant rod changes, and then complete the detection operation of the resonant rod strength. The overall operation is simple and the degree of intelligence is high.

[0003] However, in the actual working process, when the resonance rod is inspected, only a pressure is applied to the resonance rod, and there is no inspection operation on the side wall of the resonance rod. After a certain force is applied to the resonance rod, the changes on the inside and outside of the resonance rod are mainly observed manually. While the operation is simple, the inspection effect is general. Moreover, since there is no inspection operation on the bottom of the resonance rod, the inspection effect of the resonance rod is general. Therefore, a strength detection device for resonance rod manufacturing is provided. Summary of the invention

DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 12 A strength detection device for manufacturing a resonance rod comprises a workbench 1, a bracket 2 is fixedly installed on the upper side of the workbench 1, a hydraulic rod 3 is rotatably connected to the lower side of the bracket 2, a fixing ring 4 is rotatably installed on the upper side of the workbench 1, a clamping assembly is installed on the output end of the hydraulic rod 3, a plurality of cameras 28 are evenly fixedly connected to the inner wall of the bracket 2, and the clamping assembly comprises a fixing frame 5 fixedly installed on the output end of the hydraulic rod 3, a first threaded rod 6 is rotatably penetrated in the fixing frame 5, two threaded rings 7 are sleeved on the inner thread of the first threaded rod 6, the two threaded rings 7 are slidably connected to the inner wall of the fixing frame 5, and a clamping claw 8 is also fixedly connected to the outer side of the two threaded rings 7, the thread on the outer side of the first threaded rod 6 is divided into two parts, and the thread rotation directions of the two parts are opposite, so when the first threaded rod 6 rotates, the two threaded rings 7 will move towards or away from each other;

[0031] First, a driving device is fixedly connected to the lower side of the bracket 2, and the hydraulic rod 3 is fixedly connected to the output end of the driving device. Then, a display screen for controlling the switch of the hydraulic rod 3 and the power size is installed on the outside of the workbench 1. At the same time, the display screen can start the driving device, thereby driving the hydraulic rod 3 to rotate as a whole. Secondly, the two clamping jaws 8 are located on the upper side of the fixed ring 4 and opposite to the fixed ring 4. The inner walls of the two clamping jaws 8 are provided with clamping grooves. When it is necessary to perform strength testing on the resonance rod, the resonance rod is first placed between the two clamping jaws 8, and the first threaded rod 6 is rotated. Since the two threaded rings 7 are threadedly connected to the first threaded rod 6, and the two threaded rings 7 are slidably connected to the fixed frame 5, the rotating first threaded rod 6 will drive the two threaded rings 7 to move toward each other, and the two threaded rings 7 drive the clamping jaws 8 to move toward each other until the two clamping jaws 8 clamp the resonance rod. The hydraulic rod 3 is turned on through the display screen, so that the hydraulic rod 3 can drive the clamping claw 8 and the resonance rod to move through the fixed frame 5, the first threaded rod 6 and the threaded ring 7. When the resonance rod and the fixed ring 4 are against each other, the output force of the hydraulic rod 3 is adjusted to form a pressing operation on the resonance rod, and the driving device is started, thereby driving the hydraulic rod 3 and the resonance rod to rotate. After a period of time, the hydraulic rod 3 is started again to disconnect the resonance rod and the fixed ring 4, and then the resonance rod is removed, and the deformation effect of the resonance rod is observed and input into the display screen. In the process of detection, the outer surface of the resonance rod can be photographed and detected by the camera 28, and the above operation is repeated to detect multiple different resonance rods, and then the obtained data and the photographed pictures are analyzed to finally complete the detection operation of the resonance rod strength. This is a prior art and no unnecessary elaboration is made.

[0032] The side wall detection component includes a cavity 9 opened in the workbench 1, a motor 10 is fixedly installed in the cavity 9, a rotating shaft 11 is fixedly installed at the output end of the motor 10, four threaded grooves 12 are opened on the outer side of the rotating shaft 11, four connecting rings 13 are sleeved on the outer side of the rotating shaft 11, an arc plate 16 is slidably connected to the outer side of the connecting ring 13, a first connecting rod 17 is fixedly connected to the upper side of the arc plate 16, a fifth connecting plate 33 is fixedly connected to the upper side of the first connecting rod 17, a second threaded rod 36 is threadedly connected to the upper side of the fifth connecting plate 33, a moving frame 18 is rotatably connected to the upper side of the second threaded rod 36, a plurality of first pressure sensors 19 are symmetrically fixedly installed on the side wall of the moving frame 18, a plurality of first pressure sensors 19 are fixedly connected to the detection rod 20, a first connecting rod 17 is installed in the connecting ring 13 through a connecting component Two connecting rods 27, the second connecting rod 27 is slidably connected to the threaded groove 12, the connecting assembly includes a limiting groove 21 opened on the side wall of the connecting ring 13, the inner walls on both sides of the limiting groove 21 are opened with inclined grooves 22, the two inclined grooves 22 are slidably connected with inclined rods 23, the two inclined rods 23 are commonly fixedly connected with a first connecting plate 24, the first connecting plate 24 slides through the arc plate 16, the first connecting plate 24 and the second connecting rod 27 are fixedly connected, the two sides of the first connecting plate 24 are slidably connected with the second connecting plate 25, the second connecting plate 25 and the inner wall of the limiting groove 21 are fixedly connected with a first spring 26, the outer sides of the four connecting rings 13 are fixedly connected with the sliding rod 14, the bottom of the cavity 9 is opened with a sliding groove 15, the sliding rod 14 and the sliding groove 15 are slidably connected; determine and limit the movement trajectory of the connecting ring 13;

[0033] First, the first pressure sensor 19 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. Secondly, four through holes are opened on the upper side of the cavity 9. The movable frame 18 passes through the through holes, and the outer side of the movable frame 18 abuts against the inner wall of the through hole. When the resonance rod needs to be detected, the actual length between the fifth connecting plate 33 and the movable frame 18 is adjusted according to the height of the resonance rod. In this process, the second threaded rod 36 is rotated. Since the second threaded rod 36 is threadedly connected to the fifth connecting plate 33, and the outer side wall of the movable frame 18 abuts against the inner wall of the through hole, the rotating second threaded rod 36 will cause the movable frame 18 to move toward or away from the fifth connecting plate 33. Then, the thread grooves 12 located on the outer side of the rotating shaft 11 are grouped in pairs, and the two thread grooves 12 in each group are threaded. In the opposite direction, that is, when the rotating shaft 11 rotates, since the sliding rod 14 and the sliding groove 15 are slidably connected, and the sliding rod 14 and the connecting ring 13 are fixedly connected, when the second connecting rod 27 is located in the threaded groove 12, the rotating rotating shaft 11 will drive the first connecting plate 24 and the second connecting plate 25 to move through the second connecting rod 27, and the second connecting plate 25 will drive the connecting ring 13, the first connecting rod 17 and the moving frame 18 to move as a whole through the first spring 26 (because at this time, the connecting ring 13, the first connecting rod 17 and the moving frame 18 as a whole are not acted upon by any other force, the elastic coefficient of the first spring 26 can be selected to overcome the self-weight of the connecting ring 13, the first connecting rod 17 and the moving frame 18 as a whole, so the connecting ring 13, the first connecting rod 17 and the moving frame 18 can be driven by the first spring 26 to move as a whole), as shown in FIG. Fig.12 As shown, the two moving frames 18 located on the outer side of the resonance rod and the two moving frames 18 located on the inner side of the resonance rod eventually move toward the direction close to the side wall of the resonance rod. When the detection rod 20 and the side wall of the resonance rod are against each other, the moving frame 18 will not move with the connecting ring 13 due to the obstruction of the side wall of the resonance rod. The moving frame 18 drives the arc plate 16 to move through the fifth connecting plate 33 and the first connecting rod 17, and the arc plate 16 drives the first connecting plate 24 to move. Figure 7 The direction is based on Figure 7 The connecting ring 13 shown in FIG. Fig.12, counting from left to right, the connection schematic diagram of the limiting groove 21 inside the first and third connecting rings 13, the first connecting plate 24 moves along the inclined groove 22 to the upper left direction under the limiting action of the inclined groove 22 and the inclined rod 23, the first connecting plate 24 stretches the first spring 26 on the right side through the second connecting plate 25, and compresses the first spring 26 on the left side until the second connecting rod 27 moves out of the thread groove 12, causing the connecting ring 13 to not move with the rotating shaft 11. At this time, under the action of the first spring 26, the connecting ring 13 will move to the left relative to the rotating shaft 11. In the above working process, the direction of the inclined groove 22 in the limiting groove 21 inside the second and fourth connecting rings 13 refers to Figure 7 Look, it's Figure 7 The mirror image of the middle inclined groove 22, the first connecting plate 24 will move along the inclined groove 22 to the upper right, the first connecting plate 24 will compress the first spring 26 on the right and stretch the first spring 26 on the left until the second connecting rod 27 moves out of the thread groove 12, causing the connecting ring 13 to not move with the rotating shaft 11. At this time, under the action of the first spring 26, the connecting ring 13 will move to the right relative to the rotating shaft 11, and then, under the action of the first spring 26, the inclined rod 23 will return to its original position relative to the limiting groove 21. At this time, the second connecting rod 27 will enter the thread groove 12 again, and then under the obstruction of the side wall of the resonant rod, the inclined rod 23 will move again, causing the device as a whole to repeat the above operation. During the process, the first pressure sensor 19 sends out a corresponding electrical signal, and this signal will be within a certain range. When the strength of the resonance rod is detected, the driving device can be started through the display screen, so that the hydraulic rod 3 rotates, and then the resonance rod clamped on the outside of the clamp 8 rotates. In this process, the first pressure sensor 19 and the detection rod 20 can be used to perform a detection operation on the inner and outer side walls of the resonance rod. If the electrical signal sent by the first pressure sensor 19 is abnormal, it means that the inner and outer side walls of the resonance rod are damaged, and then a detection operation on the inner and outer side walls of the resonance rod can be performed. In this process, the detection rod 20 will not always perform a squeezing operation on the resonance rod, so the damage to the inner and outer side walls of the resonance rod is relatively small.

[0034] The moving frame 18 is provided with a knocking assembly, which includes a fourth connecting plate 46 fixedly installed on the side wall of the moving frame 18, a third threaded rod 37 being rotatably connected to the lower side of the fourth connecting plate 46, a third connecting plate 45 being fixedly connected to the outer side of the third threaded rod 37, a torsion spring 47 being fixedly connected between the third connecting plate 45 and the fourth connecting plate 46, a plurality of gears 44 being fixedly connected to the outer side of the third threaded rod 37, a plurality of knocking rods 39 being slidably connected in the moving frame 18, a fourth connecting rod 42 being fixedly connected to the side wall of the plurality of knocking rods 39, and a plurality of fourth connecting rods 42 being fixedly connected to the outer side of the plurality of fourth connecting rods 42. The side wall is fixedly connected with a first rack 43, the first rack 43 and the gear 44 are meshed, the lower side of the third threaded rod 37 is threadedly connected with a sleeve 34, the lower side of the sleeve 34 is fixedly connected with a moving ring 35, the side wall of the moving ring 35 is fixedly connected with a third connecting rod 38, the third connecting rod 38 and the first connecting plate 24 are fixedly connected, a plurality of deep grooves are opened in the moving frame 18, a limit rod 40 is slidably connected in the plurality of deep grooves, the limit rod 40 and the knocking rod 39 are fixedly connected, a third spring 41 is fixedly connected between the limit rod 40 and the deep groove, and determines and limits the movement trajectory of the knocking rod 39;

[0035] First, during the movement of the inclined rod 23 along the inclined slot 22, Figure 8 Based on the direction, when the knocking rod 39 moves to the left, the limiting rod 40 compresses the third spring 41 on the left and stretches the third spring 41 on the right. In the process of the second connecting rod 27 moving out of the thread groove 12, Figure 7Based on the direction, the second connecting rod 27 will drive the moving ring 35 to move upward through the first connecting plate 24 and the third connecting rod 38, and the moving ring 35 will drive the sleeve 34 to move upward. Since the sleeve 34 and the third threaded rod 37 are threadedly connected, the upward moving sleeve 34 will cause the third threaded rod 37 to rotate, thereby driving the gear 44 to rotate. When the second connecting rod 27 moves out of the thread groove 12, under the action of the first spring 26, the connecting ring 13 will move relative to the rotating shaft 11 until the first springs 26 on both sides are in a balanced state again, thereby causing the second connecting rod 27 to enter the thread groove again. In this process, the second connecting rod 27 will move to the lower right direction along the direction of the inclined groove 22 and the inclined rod 23. 7 will drive the moving ring 35 to move downward through the first connecting plate 24 and the third connecting rod 38, and the moving ring 35 will drive the sleeve 34 to move downward. Since the sleeve 34 and the third threaded rod 37 are threadedly connected, the sleeve 34 moving downward will cause the third threaded rod 37 to rotate, thereby driving the gear 44 to rotate (at this time, the third threaded rod 37 and the gear 44 rotate in the opposite direction to that just now). When the second connecting rod 27 enters the thread groove 12 again, the device as a whole will repeat the above working state, resulting in intermittent contact between the knocking rod 39 and the side wall of the resonance rod, forming a knocking effect on the inner and outer sides of the resonance rod, and then cooperate with the first pressure sensor 19 and the detection rod 20 to detect the inner and outer side walls of the resonance rod, thereby improving the strength detection effect of the resonance rod;

[0036] Furthermore, during the above working process, the threads on the outer side of the third threaded rod 37 and the threads on the inner wall of the sleeve 34 are relatively loose, that is, the thread lead angle is greater than or equal to the friction angle, so self-locking will not occur.

[0037] A bottom detection assembly is installed on the upper side of the workbench 1, and the bottom detection assembly includes two positioning rods 48, the two positioning rods 48 are fixedly connected to two of the moving frames 18, a control cylinder 49 is slidably connected to the outer sides of the two positioning rods 48, a fourth spring 32 is fixedly connected between the positioning rods 48 and the control cylinder 49, a plurality of second pressure sensors 50 are evenly fixedly connected to the outer side of the control cylinder 49, the plurality of second pressure sensors 50 are fixedly connected to the detection plate 29, a fifth connecting rod 30 is fixedly connected to the side wall of the control cylinder 49, a second rack 31 is fixedly connected to the end of the fifth connecting rod 30, and the second rack 31 is meshed with the gear 44;

[0038] First, the structure and working principle of the second pressure sensor 50 are the same as those of the first pressure sensor 19. Secondly, the two positioning rods 48 are fixedly connected to the two middle moving frames 18 respectively, that is, the positioning rod 48 is located inside the resonant rod when the resonant rod is detecting. After the length adjustment of the moving frame 18 and the fifth connecting plate 33 is completed, the detection plate 29 and the bottom of the resonant rod are abutted, and the second pressure sensor 50 sends a corresponding electrical signal. During the detection process of the resonant rod, when the gear 44 rotates, the gear 44 will drive the meshing second rack 31 to move back and forth, and the second rack 31 The control cylinder 49 is driven to move back and forth through the fifth connecting rod 30, and the control cylinder 49 drives the detection plate 29 to move back and forth through the second pressure sensor 50. The detection plate 29 is always against the bottom of the resonance rod and sends out an electrical signal. During this process, the size of the electrical signal sent out by the second pressure sensor 50 can be observed. If the electrical signal is always within a reasonable range, it means that there is no problem with the bottom of the resonance rod. If the electrical signal suddenly increases or decreases, it means that there is an abnormality at the bottom of the resonance rod, and the detection needs to be stopped. A more detailed inspection of the bottom of the resonance rod is required.

[0039] In the present invention, when it is necessary to test the strength of the resonance rod, the two clamping claws 8 are driven by the first threaded rod 6 and the threaded ring 7 to clamp the resonance rod, and the hydraulic rod 3 is turned on through the display screen, so that the hydraulic rod 3 can drive the clamping claws 8 and the resonance rod to move. When the resonance rod and the fixed ring 4 are against each other, the output force of the hydraulic rod 3 is adjusted to form a pressing operation on the resonance rod, and the driving device is started, thereby driving the hydraulic rod 3 and the resonance rod to rotate. After a period of time, the hydraulic rod 3 is started again to disconnect the resonance rod and the fixed ring 4, and then the resonance rod is removed, and the deformation effect of the resonance rod is observed and input into the display screen. In the process of testing, the outer surface of the resonance rod can be photographed and tested by the camera 28, and the above operation is repeated to test multiple different resonance rods, and then the obtained data and the photographed pictures are analyzed to finally complete the detection operation of the strength of the resonance rod. This is a prior art and no unnecessary elaboration is made.

[0040] When the resonance rod needs to be tested, the actual length between the fifth connecting plate 33 and the moving frame 18 is adjusted according to the height of the resonance rod. Then, the thread grooves 12 located on the outside of the rotating shaft 11 are grouped in pairs, and the thread rotation directions of the two thread grooves 12 in each group are opposite, that is, when the rotating shaft 11 rotates, since the sliding rod 14 and the sliding groove 15 are slidably connected, and the sliding rod 14 and the connecting ring 13 are fixedly connected, when the second connecting rod 27 is located in the thread groove 12, the rotating rotating shaft 11 will drive the first connecting plate 24 and the second connecting plate 25 to move through the second connecting rod 27, and the second connecting plate 25 will drive the connecting ring 13, the first connecting rod 17 and the moving frame 18 to move as a whole through the first spring 26, as shown in FIG. Fig.12As shown, the two moving frames 18 located on the outer side of the resonance rod and the two moving frames 18 located on the inner side of the resonance rod eventually move toward the direction close to the side wall of the resonance rod. When the detection rod 20 and the side wall of the resonance rod are against each other, the moving frame 18 will not move with the connecting ring 13 due to the obstruction of the side wall of the resonance rod. The moving frame 18 drives the arc plate 16 to move through the fifth connecting plate 33 and the first connecting rod 17, and the arc plate 16 drives the first connecting plate 24 to move. Figure 7 The direction is based on Figure 7 The connecting ring 13 shown in FIG. Fig.12 , counting from left to right, there is a connection diagram of the first and third connecting rings 13 internal limit grooves 21. Under the limiting action of the inclined groove 22 and the inclined rod 23, the first connecting plate 24 moves along the inclined groove 22 to the upper left direction. The first connecting plate 24 stretches the first spring 26 on the right side through the second connecting plate 25 and compresses the first spring 26 on the left side until the second connecting rod 27 moves out of the thread groove 12, causing the connecting ring 13 to not move with the rotating shaft 11. At this time, under the action of the first spring 26, the connecting ring 13 will move to the left relative to the rotating shaft 11, and then, under the action of the first spring 26, the inclined rod 23 will return to its original position relative to the limit groove 21. At this time, the second connecting rod 27 will enter the thread groove 12 again, and then under the obstruction of the side wall of the resonance rod. Under, the inclined rod 23 moves again, so that the whole device repeats the above operation. During this process, the first pressure sensor 19 sends out a corresponding electrical signal, and this signal will be in a certain range. When the strength of the resonance rod is detected, the driving device can be started through the display screen, so that the hydraulic rod 3 rotates, and then the resonance rod clamped on the outside of the clamping claw 8 rotates. The first pressure sensor 19 and the detection rod 20 can form a detection operation on the inner and outer side walls of the resonance rod. If the electrical signal sent by the first pressure sensor 19 is abnormal, it means that the inner and outer side walls of the resonance rod are damaged, and then the detection operation on the inner and outer side walls of the resonance rod can be formed. In addition, during this process, the detection rod 20 will not always form a squeezing operation on the resonance rod, so the damage to the inner and outer side walls of the resonance rod is relatively small.

[0041] In the process of the second connecting rod 27 being moved out of the thread groove 12, Figure 7Based on the direction, the second connecting rod 27 will drive the moving ring 35 to move upward through the first connecting plate 24 and the third connecting rod 38, and the moving ring 35 will drive the sleeve 34 to move upward. Since the sleeve 34 and the third threaded rod 37 are threadedly connected, the upward moving sleeve 34 will cause the third threaded rod 37 to rotate, thereby driving the gear 44 to rotate. When the second connecting rod 27 moves out of the thread groove 12, under the action of the first spring 26, the connecting ring 13 will move relative to the rotating shaft 11 until the first springs 26 on both sides are in a balanced state again, thereby causing the second connecting rod 27 to enter the thread groove again. In this process, the second connecting rod 27 will move to the lower right direction along the direction of the inclined groove 22 and the inclined rod 23. 7 will drive the moving ring 35 to move downward through the first connecting plate 24 and the third connecting rod 38, and the moving ring 35 will drive the sleeve 34 to move downward. Since the sleeve 34 and the third threaded rod 37 are threadedly connected, the sleeve 34 moving downward will cause the third threaded rod 37 to rotate, thereby driving the gear 44 to rotate (at this time, the third threaded rod 37 and the gear 44 rotate in the opposite direction to that just now). When the second connecting rod 27 enters the thread groove 12 again, the device as a whole will repeat the above working state, resulting in intermittent contact between the knocking rod 39 and the side wall of the resonance rod, forming a knocking effect on the inner and outer sides of the resonance rod, and then cooperate with the first pressure sensor 19 and the detection rod 20 to detect the inner and outer side walls of the resonance rod, thereby improving the strength detection effect of the resonance rod;

[0042] After the length adjustment of the moving frame 18 and the fifth connecting plate 33 is completed, the detection plate 29 is against the bottom of the resonance rod, and the second pressure sensor 50 sends out a corresponding electrical signal. During the detection of the resonance rod, when the gear 44 rotates, the gear 44 will drive the meshing second rack 31 to move back and forth, and the second rack 31 drives the control cylinder 49 to move back and forth through the fifth connecting rod 30. The control cylinder 49 drives the detection plate 29 to move back and forth through the second pressure sensor 50. The detection plate 29 is always against the bottom of the resonance rod and keeps sending out electrical signals. During this process, the size of the electrical signal sent by the second pressure sensor 50 can be observed. If the electrical signal is always within a reasonable range, it means that there is no problem with the bottom of the resonance rod. If the electrical signal suddenly increases or decreases, it means that there is an abnormality at the bottom of the resonance rod, and the detection needs to be stopped. A more detailed inspection of the bottom of the resonance rod is required.
