Description

Technical Field

[0001] The present invention relates to the field of mechanical testing, and particularly to an operating performance test device.

Background Art

[0002] A bi-directional telescopic locking device is a device applied to an aircraft. The telescopic shafts at both ends thereof can perform telescoping synchronously. It can be used for locking connection between connecting components whose states need to be changed. For example, it is used on folding wings. When operating the bi-directional telescopic locking device to perform telescoping, usually a driving torque is applied to make it perform active telescoping.

Specific Embodiments

[0022] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation to the present invention.

[0023] The operating performance test device of the present invention is used to test the operating performance of a two-way telescopic locking device, and it can test the operating performance when the two-way telescopic locking device performs telescopic movement under pressure.

[0024] As Figures 1 - 6 shown, the operating performance test device of the present invention includes a tension module 10, a lever assembly 20, a counterweight module 30, a pressure module 40, a pressure sensor 50, and a torque measuring device (not shown in the figure). The non-end portion of the lever assembly 20 is disposed on the pressure module 40, and the two ends of the lever assembly 20 are respectively connected to the counterweight module 30 and the tension module 10, so as to form a lever structure, and then the lever principle can be used to increase the upper limit of the rated load; the counterweight module 30 is used to adjust the pressure magnitude, and its counterweight can be set according to the test requirements. The pressure module 40 is used to transfer the pressure to the test part, such as a two-way telescopic locking device, so as to apply pressure to the test part to simulate the situation when the test part performs telescopic movement under pressure. The pressure sensor 50 is used to measure the applied pressure; the torque measuring device is used to measure the driving torque when the test part performs telescopic movement under pressure, and it is used to evaluate the operating performance of the test part.

[0025] As Figure 1 、 Figure 2 、 Figure 3 shown, the pressure module 40 is connected to the non-end portion of the lever assembly 20, and it includes a pressing block 41, a pressure rotation block 42, a support block 43, and a pressing block 44.

[0026] As Figure 2 、 Figure 3As shown, the pressing block 41 is used to support and connect the pressure rotating block 42 and transmit pressure downward.

[0027] As Figure 2 , Figure 3 shown, the pressure rotating block 42 is rotatably connected to the pressing block 41, and is used to support the non-end position of the lever assembly 20 to form a lever structure. A first through groove 421 for accommodating the lever assembly 20 is provided on the pressure rotating block 42. The shape of the first through groove 421 matches the shape of the lever assembly 20. In this embodiment, the lever assembly 20 is in the shape of a round rod, and the first through groove 421 is an arc-shaped groove.

[0028] As Figure 2 , Figure 3 shown, the support block 43 is used to support the pressure module 40, and is provided with a first shaft hole 431 for the end of the test part to pass through. The axis of the first shaft hole 431 is perpendicular to the first through groove 421, that is, perpendicular to the lever assembly 20. The shape of the first shaft hole 431 matches the shape of the end of the test part - the shape of the telescopic shaft. In this embodiment, it is a round hole.

[0029] As Figure 2 , Figure 3 shown, the pressing block 44 is arranged between the support block 43 and the pressing block 41, and is used to directly apply pressure to the test part. The pressing block 44 is a movable part and is movably connected to the support block 43. In this embodiment, the pressing block 44 is lapped on the support block 43. A second shaft hole 441 for the end of the test part to pass through is provided on the pressing block 44. The axis of the second shaft hole 441 is perpendicular to the first through groove 421, that is, perpendicular to the lever assembly 20. The shape of the second shaft hole 441 matches the shape of the end of the test part. In this embodiment, it is a round hole.

[0030] As Figure 2 , Figure 3 shown, the positions of the first shaft hole 431 and the second shaft hole 441 are basically corresponding, and the axis of the first shaft hole 431 is parallel to the axis of the first shaft hole 431. During testing, the axis of the first shaft hole 431 can coincide with the axis of the second shaft hole 441 or have a slight offset. Whether the axes of the first shaft hole 431 and the second shaft hole 441 completely coincide is related to the pressure applied to the pressing block 44.

[0031] The first shaft hole 431 and the second shaft hole 441 form the shaft hole on the pressure module for the end of the test part to pass through.

[0032] As Figure 2 , Figure 3As shown, the pressing block 41, the pressure rotating block 42, the pressing block 44, and the supporting block 43 can form the pressure module 40 of this embodiment. The pressure rotating block 42 supports the non-end part of the lever assembly 20, and the pressure from the lever assembly 20 it bears can be transmitted to the pressing block 44 through the pressing block 41, and then can be applied to the test part through the pressing block 44.

[0033] As Figure 2 , Figure 3 shown, the pressure sensor 50 is arranged in the pressure module 40 and is used to measure the pressure load applied to the test part. In this embodiment, the pressure sensor 50 is arranged between the pressing block 41 and the pressing block 44, and it can measure the pressure applied to the pressing block 44 in real time.

[0034] As Figure 1 shown, the lever assembly 20 is in the shape of a long rod and is used to form a lever structure to increase the upper limit of the rated load through the lever principle. The lever assembly 20 is arranged on the pressure module 40, and its two ends respectively extend out of the pressure module 40 to form a first free end 21 and a second free end 22. The first free end 21 is used to connect the counterweight module 30, and the second free end 22 is used to connect with the tension module 10, thus forming a lever structure.

[0035] As Figure 1 shown, a partial position of the non-end part of the lever assembly 20 is embedded in the first through groove 421 of the pressure rotating block 42. The contact part 442 between the lever assembly 20 and the first through groove 421 is called the fulcrum of the lever assembly 20. The fulcrum of the lever assembly 20 is close to the second free end 22 and far from the first free end 21, and its specific length ratio can be set as needed, and this embodiment does not limit it.

[0036] As Figure 1 shown, the counterweight module 30 is suspended at the first free end 21 of the lever assembly 20. The weight of the counterweight module 30 can be set as needed. For example, the load applied to the test part can be adjusted by increasing or decreasing the weight of the counterweight module 30. The counterweight module 30 can be selected with structures such as weights. The counterweight module 30 can be suspended at the first free end 21 of the lever assembly 20 in a known manner, and it should be convenient for the tester to increase or decrease the counterweight. In this embodiment, the counterweight module 30 is suspended at the first free end 21 of the lever assembly 20 through a hook 31.

[0037] As Figure 1 shown, the tension module 10 acts on the second free end 22 of the lever assembly 20. As Figure 4 , Figure 5As shown, the tension module 10 includes a support base 11 and a tension rotating block 12 that are movably connected. The support base 11 is fixedly arranged, and the tension rotating block 12 is rotatably connected to the support base 11. A second through groove 121 for accommodating the lever assembly 20 is provided on the tension rotating block 12, and the second free end 22 of the lever assembly 20 is arranged in the second through groove 121, so that a tension can be applied to the second free end 22 of the lever assembly 20 through the tension module 10.

[0038] For the operating performance test device of the present invention, both the tension rotating block 12 and the pressure rotating block 42 can rotate. Therefore, it can provide a moving space for the inclination of the lever assembly 20; when the weight module 30 is increased or decreased, the lever assembly 20 can drive the pressure rotating block 42 and the tension rotating block 12 to rotate adaptively to meet the inclination of the lever assembly 20.

[0039] The torque measuring device (not shown in the figure) is used to test the driving torque when the test part makes a telescopic movement under pressure. The torque measuring device can select a well-known torque measuring device, for example, a digital display torque wrench, a torque sensor, etc. The torque measuring device is arranged on the test part.

[0040] During the test, as Figure 1 、 Figure 6 shown, the end of the test part - the telescopic shaft is placed in the first shaft hole 431 and the second shaft hole 441. A suitable weight module 30 is arranged on the first free end 21 of the lever assembly 20. At this time, the fulcrum of the lever assembly 20 presses the pressure module 40, and the pressure module 40 transmits the pressure downward to apply a load to the telescopic shaft of the test part. At this time, a driving torque is applied to operate the test part to make the telescopic shaft telescopic, so that the performance of the test part during telescopic operation under a huge pressure load can be tested. During the test process, the pressure load applied to the test part is measured by the pressure sensor 50, and the driving torque is measured by the torque measuring device; by increasing or decreasing the weight module 30, the magnitude of the pressure load can be adjusted; by analyzing the values of the pressure load and the corresponding driving torque, the operating performance of the test part can be evaluated.

[0041] To introduce the structure of the operating performance test device of the present invention more clearly, the following will be introduced with a specific structure. It should be understood that the operating performance test device of the present invention should not be limited to the specific structure introduced in the following embodiments.

[0042] As Figure 2 、 Figure 3 shown, the pressure module 40 includes a pressing block 41, a pressure rotating block 42, a support block 43 and a pressing block 44.

[0043] In this embodiment, as Figure 2 、Figure 3 As shown, the pressing block 41 includes a first support ear 411 and a connecting portion 412 formed integrally. The first support ears 411 are spaced from each other, and their specific shapes are not limited. The connecting portion 412 is connected between the ends of the first support ears 411. One end of the connecting portion 412 facing away from the first support ear 411 is planar, and it is used to fit with the pressure sensor 50 to facilitate the transmission of pressure for pressure measurement. At one end of the first support ear 411 opposite to the connecting portion 412, there is a first rotation hole 413, and the axial direction of the first rotation hole 413 is perpendicular to the lever assembly 20. The first rotation hole 413 can be a standard circular hole or a U-shaped hole with an upward opening, as long as it can form a rotational connection with the pressure rotation block 42 to facilitate the rotation of the pressure rotation block 42. In this embodiment, the first rotation hole 413 is a U-shaped hole with an upward opening.

[0044] As Figure 2 、 Figure 3 shown, the pressure rotation block 42 includes a first rotating shaft portion 422 and a first follower portion 423 formed integrally. The first rotating shaft portion 422 is cylindrical and protrudes from opposite ends of the first follower portion 423, and it is used for rotational connection within the first rotation hole 413. The shape of the first follower portion 423 can be set as needed, and its thickness should be less than the distance between the first support ears 411. There is a first through groove 421 on the first follower portion 423. The axial direction of the first through groove 421 is perpendicular to the axial direction of the first rotating shaft portion 422. The first through groove 421 is used for embedding the lever assembly 20, and its shape matches that of the lever assembly 20. The first through groove 421 can be a standard circular through hole or a U-shaped groove with an upward opening. In this embodiment, the first through groove 421 is a U-shaped groove with an upward opening.

[0045] As Figure 2 、 Figure 3 shown, the first follower portion 423 is arranged between the first support ears 411, and the first rotating shaft portion 422 is rotationally connected at the first rotation hole 413. Therefore, the pressure rotation block 42 can rotate relative to the pressing block 41. When the weight of the counterweight module 30 changes, the pressure rotation block 42 can rotate correspondingly under the action of the lever assembly 20. The height of the first support ear 411 should be such that the first follower portion 423 will not interfere with the connecting portion 412 during the rotation process.

[0046] As Figure 2 、 Figure 3As shown, the support block 43 includes an integrally formed support portion 432 and a substrate portion 433. The substrate portion 433 is in a flat plate shape and is fixed on the base platform 60. The support portion 432 protrudes from the surface of the substrate portion 433. The support portions 432 are relatively spaced apart, and an insertion space for inserting the pressing block 44 is formed therebetween. The shape of the support portion 432 is not limited as long as it can play a corresponding supporting role. The first shaft holes 431 are respectively provided on the support portion 432. To facilitate the insertion of the pressing block 44 between the support portions 432, chamfers 434 are provided at the top of the support portions 432 and are arranged facing each other to form a flared shape, which is conducive to the insertion of the pressing block 44. The top of the support block 43 should be able to provide a certain supporting plane to facilitate the lapping of the pressing block 44.

[0047] As Figure 2 , Figure 3 shown, the pressing block 44 includes an integrally formed contact portion 442 and a pressing portion 443. The contact portion 442 is in a flat plate shape, which is conducive to fitting with the pressure sensor 50 to facilitate the measurement and transmission of pressure. The pressing portion 443 protrudes from the surface of the contact portion 442, and its thickness should be less than the distance between the support portions 432, so as to facilitate insertion between the support portions 432. To match the chamfer 434 structure at the top of the support portion 432, a wedge surface 444 is provided at the connecting portion of the pressing portion 443 and the contact portion 442, and the angle of the wedge surface 444 matches the angle of the chamfer 434. The second shaft hole 441 is provided on the pressing portion 443.

[0048] As Figure 2 , Figure 3 shown, the contact portion 442 is lapped on the top of the support portion 432, and the pressing portion 443 is inserted between the support portions 432, so that the position of the second shaft hole 441 corresponds to the position of the first shaft hole 431.

[0049] As Figure 2 , Figure 3 shown, the pressure sensor 50 is arranged between the pressing block 44 and the pressing block 41. Specifically, the pressure sensor 50 is clamped between the contact portion 442 and the connecting portion 412. For the fixation of the pressure sensor 50, reference can be made to well-known technologies. For example, corresponding jacks can be provided on the contact portion 442 of the pressing block 44, and the pressure sensor 50 is inserted into the jacks to be relatively fixed to the pressing block 44.

[0050] As Figure 4 , Figure 5 shown, the tension module 10 includes a support seat 11 and a tension rotating block 12 that are movably connected.

[0051] AsFigure 1 As shown, the support base 11 is fixedly arranged on the base platform 60 and is close to the pressure module 40. The height of the support base 11 is similar to the height of the pressure module 40. The support base 11 can be an integrally formed structure or an assembly composed of multiple parts, and this embodiment does not limit it. As Figure 4 、 Figure 5 shown, at the top of the support base 11, there are second support ears 111 spaced apart from each other. The second support ears 111 are used to support the tension rotation block 12 and form a rotational connection with the tension rotation block 12. The shape of the second support ears 111 is not limited. In this embodiment, it is in the shape of a flat plate. Second rotation holes 112 are respectively arranged on the second support ears 111. The second rotation holes 112 are perpendicular to the lever assembly 20. The horizontal height of the second rotation holes 112 is the same as the horizontal height of the first rotation holes 413. The second rotation holes 112 can be standard circular holes or open U-shaped holes. In this embodiment, the second rotation holes 112 are U-shaped holes with the openings facing the pressure module 40.

[0052] As Figure 4 、 Figure 5 shown, the tension rotation block 12 includes an integrally formed second rotating shaft portion 122 and a second follower portion 123. The second rotating shaft portion 122 is cylindrical and protrudes from opposite ends of the second follower portion 123. It is used to be lapped in the second rotation holes 112 to form a rotational connection with the support base 11. The shape of the second follower portion 123 is not limited. It is arranged between the second support ears 111 and can rotate without interfering with the support base 11. A second through slot 121 is arranged on the tension rotation block 12, and the shape of the second through slot 121 matches the shape of the lever assembly 20. The second through slot 121 can be a circular through hole or an open U-shaped slot. In this embodiment, the second through slot 121 is a U-shaped slot with the opening facing downwards, and the second free end 22 of the lever assembly 20 is embedded in the second through slot 121.

[0053] As Figure 4 、 Figure 5 shown, the tension rotation block 12 is rotationally connected to the support base 11 through its second rotating shaft portion 122 at the second rotation holes 112, and the tension rotation block 12 interacts with the lever assembly 20 through the second through slot 121. When the weight of the counterweight module 30 changes, the tension rotation block 12 can rotate correspondingly under the action of the lever assembly 20.

[0054] When the test part is a two-way telescopic locking device, since the test part extends outward synchronously at both ends, therefore, for the operation performance test device of this embodiment, the lever assembly 20, the tension module 10, the pressure module 40, and the counterweight module 30 are all provided with two groups (such as Figure 1 , Figure 6 shown). To facilitate the setting of the tension module 10 and the pressure module 40, the operation performance test device further includes a base platform 60. The structure of the base platform 60 can be set as required, and it provides a support platform. The pressure module 40 is arranged on the base platform 60 at intervals. Among them, the support block 43 of the pressure module 40 is fixedly connected to the base platform 60. The shaft holes of the two groups of pressure modules 40 are located on the same straight line for inserting the telescopic shafts at both ends of the test part. A group of lever assemblies 20 are respectively arranged on the two groups of pressure modules 40, and the lever assemblies 20 are respectively movably connected to the pressure rotating blocks 42. The counterweight modules 30 are respectively arranged at the first free ends 21 of the respective lever assemblies 20, and the second free ends 22 of the respective lever assemblies 20 interact with the tension module 10 respectively.

[0055] The distance between the two groups of pressure modules 40 at intervals is related to the length dimension of the test part.

[0056] Since the support block 43 and the pressure application block 44 of the pressure module 40 are movably connected, to ensure the safety of the test device, as Figure 1 shown, a limit frame 70 can be arranged outside each pressure module 40. The limit frame 70 covers outside the pressure module 40, which does not affect the normal installation of the test part, and its bottom is fixedly connected to the support block 43 or the base platform 60, so as to limit and protect the pressure module 40.

[0057] In addition, as Figure 1 shown, a protection frame 80 can also be arranged outside the counterweight module 30 to avoid potential safety hazards caused by the dropping of the counterweight module 30 during the test. The protection frame 80 is located outside the counterweight module 30, which does not affect the normal operation of the lever assembly 20.

[0058] Thus, the operation performance test device of the present invention is formed. The counterweight module 30, the lever assembly 20, the pressure module 40, and the tension module 10 form a lever structure. The pressure module 40 is in the fulcrum position of the lever structure, and it can bear the pressure of the lever assembly 20 to apply a pressure load to the test part; when the counterweight module 30 is increased or decreased, the pressure borne by the pressure module 40 changes, so as to adjust the pressure load applied to the test part, and further test the operation performance - driving torque of the test part when performing telescopic operation under the pressure load. By setting the lever structure, the present invention can greatly improve the upper limit of the rated load.

[0059] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Under the condition of not deviating from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
