Technical Field
[0001] The utility model belongs to the technical field of aerospace, and in particular relates to a hardness detection device for aerospace nuts. Background Art
[0002] In recent years, the field of aerospace technology has developed rapidly, and the safety of fasteners used in aerospace equipment has become particularly important. It should be noted that when selecting the material of aerospace fasteners, specific strength, fatigue resistance, corrosion resistance, rigidity, brittleness, compatibility, heat resistance and other properties are important indicators. The aerospace nut hardness testing device is an important device for hardness testing of aerospace nuts, which can intuitively reflect the hardness quality of the nut through data.
[0003] The structure of the testing platform currently used for the nuts to be tested is relatively simple. When the nuts placed on it are tested for hardness, the nuts are prone to move, which reduces the detection accuracy of the device and easily causes scratches on the surface of the nuts.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0005] In view of the problems in the related technology, the utility model proposes an aerospace nut hardness testing device to overcome the above technical problems existing in the existing related technology.

[0007] The utility model is an aerospace nut hardness testing device, comprising a body, a lifting assembly is arranged in the middle of the body, lifting columns are arranged on the peripheral side of the lifting assembly, a lifting platform is fixedly installed on the upper surface of the lifting column, load-bearing blocks are fixedly installed on both sides of the lifting platform, a moving assembly is arranged on the upper surface of the lifting platform, a rotating tooling runs through the moving assembly, and a hardness needle is fixedly installed on the top of the inner wall of the body.
[0008] Furthermore, the lifting assembly includes a first screw rod, and a rotating bearing is sleeved on the peripheral side surface of the first screw rod, and the rotating bearing is used to drive the first screw rod to rise.
[0009] Furthermore, the moving assembly includes a guide plate, the guide plate is fixedly mounted on the upper surface of the lifting platform, and a first moving block is provided on the upper surface of the guide plate.
[0010] Furthermore, the moving assembly also includes a second moving block, which is fixedly mounted on one end of the upper surface of the lifting platform.
[0011] Furthermore, the rotating fixture includes a second screw rod, the second screw rod passes through the first moving block and the second moving block, and one end of the second screw rod passes through and is fixedly installed with a rotating rod, and the rotating rod is used to drive the second screw rod to rotate.
[0012] Furthermore, a limiting column is fixed on the upper surface of the first moving block and the second moving block, and a plurality of limiting blocks are fixedly mounted on one side of the limiting column.

[0014] The utility model has the following beneficial effects:
[0015] Through the above technical scheme, the utility model allows an operator to place the nut to be tested on the upper surface of the load-bearing block, and then rotates the rotating rod to drive the second screw to rotate. The second screw rotates and simultaneously drives the first moving block to move. During the movement of the first moving block, the nut to be tested on the load-bearing block is pushed to gradually move toward the second moving block until the nut to be tested is fixed, thereby keeping the nut to be tested in a stable state as a whole, thereby solving the problem that when the nut to be tested is directly placed above the testing platform for hardness testing, the nut is prone to move, which reduces the testing accuracy of the device and easily causes scratches on the surface of the nut.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0026] See also Figure 1-Figure 4 As shown, the utility model is an aerospace nut hardness testing device, including a lifting component 2 arranged in the middle of a body 1, a lifting column 3 is arranged on the peripheral side of the lifting component 2, a lifting platform 4 is fixedly installed on the upper surface of the lifting column 3, load-bearing blocks 19 are fixedly installed on both sides of the lifting platform 4, and a moving component 5 is arranged on the upper surface of the lifting platform 4, a rotating tooling 6 is passed through the moving component 5, and a hardness needle 18 is fixedly installed on the top of the inner wall of the body 1.
[0027] Since the upper surface of the lifting platform 4 is provided with a moving component 5, and the moving component 5 is penetrated by a rotating tool 6, when in use, the operator places the nut to be tested in the middle of the moving component 5, and then moves the moving component 5 by rotating the rotating tool 6, so that the nut to be tested is fixed in the middle of the moving component 5. Since the peripheral side of the lifting component 2 is provided with a lifting column 3, and the upper surface of the lifting column 3 is fixedly installed with the lifting platform 4, after the nut to be tested is fixed, the lifting component 2 is rotated. When the lifting component 2 rotates, the lifting component 2 drives the lifting column 3 and simultaneously drives the lifting platform 4 to move upward. Since the upper surface of the lifting platform 4 is provided with a moving component 5, when the lifting platform 4 rises, the lifting platform 4 drives the moving component 5 to move upward, so that the upper surface of the nut to be tested fixed in the middle of the moving component 5 contacts the hardness needle 19, the lifting component 2 is stopped, and then the hardness needle 18 is started, so that the hardness needle 18 gradually pressurizes the upper surface of the nut to be tested to measure the hardness of the nut to be tested.
[0028] The utility model allows an operator to place the nut to be tested on the upper surface of the load-bearing block 19, and then rotate the rotating tool 6. The rotating tool 6 drives the moving assembly 5 to move so that the nut to be tested is fixed in the middle of the moving assembly 5, thereby keeping the nut to be tested in a stable state as a whole, thereby solving the problem that when the nut to be tested is directly placed above the testing platform for hardness testing, the nut is prone to movement, which reduces the testing accuracy of the device and easily causes scratches on the surface of the nut.
[0029] In one embodiment, for the above-mentioned lifting assembly 2, the lifting assembly 2 includes a first screw rod 7, and a rotating bearing 8 is sleeved on the peripheral side surface of the first screw rod 7, and the rotating bearing 8 is used to drive the first screw rod 7 to rise.
[0030] When in use, since the circumferential side surface of the first screw rod 7 is sleeved with a rotating bearing 8, the operator rotates the rotating bearing 8. When the rotating bearing 8 rotates, the rotating bearing 8 drives the first screw rod 7 to rotate through the internal thread, thereby solving the problem of the first screw rod 7 lacking a driving mechanism.
[0031] In one embodiment, for the above-mentioned moving assembly 5 , the moving assembly 5 includes a guide plate 9 , the guide plate 9 is fixedly mounted on the upper surface of the lifting platform 4 , and a first moving block 10 is disposed on the upper surface of the guide plate 9 .
[0032] When in use, since the guide plate 9 is fixedly mounted on the upper surface of the lifting platform 4, and a first moving block 10 is provided on the upper surface of the guide plate 9, when the first moving block 10 is driven, the first moving block 10 moves along the track of the guide plate 9, thereby solving the problem of the lack of a moving track when the first moving block 10 moves.
[0033] The first moving block 10 is provided with a thread inside.
[0034] In one embodiment, for the above-mentioned moving assembly 5 , the moving assembly 5 further includes a second moving block 11 , and the second moving block 11 is fixedly mounted on one end of the upper surface of the lifting platform 4 .
[0035] When in use, since the second moving block 11 is fixedly installed at one end of the upper surface of the lifting platform 4, when the first moving block 10 is driven, the first moving block 10 approaches the second moving block 11 along the trajectory of the guide plate 9, thereby fixing the nut to be tested placed in the middle of the first moving block 10 and the second moving block 11, and thus keeping the nut to be tested in a fixed state during detection.
[0036] The second moving block 11 has a thread inside.
[0037] In one embodiment, for the above-mentioned rotating tooling 6, the rotating tooling 6 includes a second screw 12, the second screw 12 passes through the interior of the first moving block 10 and the second moving block 11, and one end of the second screw 12 passes through and is fixedly installed with a rotating rod 13, and the rotating rod 13 is used to drive the second screw 12 to rotate.
[0038] When in use, since the second screw 12 passes through the inside of the first moving block 10 and the second moving block 11, and one end of the second screw 12 passes through and is fixedly installed with a rotating rod 13, when the operator rotates the rotating rod 13, the rotating rod 13 drives the second screw 12 to rotate, and at the same time, the second screw 12 drives the first moving block 10 to move through the circumferential side thread, thereby solving the problem of the first moving block 10 lacking a power mechanism.
[0039] In one embodiment, for the first moving block 10 , a limiting column 14 is fixed on the upper surface of the first moving block 10 and the second moving block 11 , and a plurality of limiting blocks 15 are fixedly mounted on one side of the limiting column 14 .
[0040] When in use, since the limiting columns 14 are fixed on the upper surfaces of the first moving block 10 and the second moving block 11, and a plurality of limiting blocks 15 are fixedly installed on one side of the limiting columns 14, when the first moving block 10 is driven by the second screw rod 12, the first moving block 10 drives the limiting blocks 15 to move through the limiting columns 14, thereby fixing the nut to be tested. Since there are a plurality of limiting blocks 15, the nut to be tested is effectively prevented from moving during detection.
[0041] In one embodiment, for the above-mentioned operation slot 16, the front side of the body 1 is provided with the operation slot 16, and the upper side of the operation slot 16 is provided with a display slot 17, and the display slot 17 is used to install a display screen.
[0042] In summary, with the aid of the above technical solution of the utility model, the operator places the nut to be tested on the upper surface of the load-bearing block 19, and then rotates the rotating rod 13. The rotating rod 13 rotates while driving the second screw 12 to rotate. The second screw 12 synchronously drives the first moving block 10 to move along the central axis of the second screw 12 toward the second moving block 11, thereby fixing the nut to be tested on the upper surface of the load-bearing block 19. After the nut to be tested is fixed, the rotating bearing 8 is rotated. When the rotating bearing 8 rotates, the rotating bearing 8 drives the first screw 7 to rotate through the internal thread. The first screw 7 drives the lifting platform 4 to move upward, so that the guide plate 9 arranged on the upper surface of the lifting platform 4 moves upward, and at the same time, drives the first moving block 10 and the second moving block 11 to move upward. When the first moving block 10 and the second moving block 11 move upward, the nut to be tested fixed at the middle of the limit block 15 on one side of the first moving block 10 and the second moving block 11 moves upward until the upper surface of the nut to be tested contacts the hardness needle 18, and then starts the hardness needle 18, so that the hardness needle 18 gradually pressurizes the upper surface of the nut to be tested to measure the hardness of the nut to be tested.
[0043] Through the above technical solution, the operator places the nut to be tested on the upper surface of the load-bearing block 19, and then rotates the rotating rod 13 to drive the second screw 12 to rotate. The second screw 12 rotates and simultaneously drives the first moving block 10 to move. During the movement of the first moving block 10, the nut to be tested on the load-bearing block 19 is pushed to gradually move toward the second moving block 10 until the nut to be tested is fixed, thereby keeping the nut to be tested in a stable state as a whole, thereby solving the problem that when the nut to be tested is placed directly above the testing platform for hardness testing, the nut is prone to move, which reduces the detection accuracy of the device and easily causes scratches on the surface of the nut.
