Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] Embodiment 1

[0026] See also Figure 1 - Figure 4 The utility model provides a pressure measuring device for aircraft parts, comprising: a protective box 1, a moving mechanism is provided in the protective box 1, a pressure measuring mechanism is provided at the output end of the moving mechanism, a loading shell 2 is provided in the protective box 1 and below the pressure measuring mechanism, wherein a box door is hingedly connected to the front surface of the protective box 1, and an observation window is provided on the surface of the box door;

[0027] A shaft 3 rotatably connected to the protection box 1 is fixedly mounted on both sides of the object-carrying shell 2. A driving member for rotating the shaft 3 is provided on one side of the protection box 1. A clamping mechanism is provided inside the object-carrying shell 2.

[0028] An electric push rod 1 4 is fixedly installed on one side of the loading shell 2, and the output end of the electric push rod 1 4 penetrates into the loading shell 2 and is fixedly connected with a cleaning push plate 5, and a baffle 6 is hinged on the other side of the loading shell 2. Electric push rods 2 7 are hinged on both sides of the loading shell 2, and the output end of the electric push rod 2 7 is movably connected to the baffle 6 through a pin shaft;

[0029] Two limiting slide rails 8 are symmetrically fixedly installed on the inner bottom wall of the protection box 1. A connecting block 9 is slidably engaged in the limiting slide rail 8. A collecting box 10 is fixedly installed between the opposite surfaces of the two connecting blocks 9.

[0030] When in use, the parts are placed in the carrier shell 2 and the protective box 1 is closed. The parts are fixed by the clamping mechanism, and then the parts are pressure tested by the pressure measuring mechanism. During the process, the pressure measuring mechanism is driven to move by the moving mechanism to adjust the pressure measuring position. If the parts are unqualified and broken, the baffle 6 and the carrier shell 2 can block the fragments to prevent the fragments from flying around. When collecting the fragments, the clamping mechanism is reset, and then the shaft 3 is driven to rotate a certain angle by the driving member, so that the carrier shell 2 is tilted, and the baffle 6 is driven to be hinged open by the electric push rod 2 7 to make the fragments fall. The cleaning push plate 5 is driven by the electric push rod 4 to move the debris in the loading shell 2, so as to push the debris in the loading shell 2 to be quickly discharged and dropped into the collecting box 10 for collection to prevent residue. Then the protective box 1 is opened, and the collecting box 10 is pulled to drive the connecting block 9 to move out from the limiting slide rail 8, so that personnel can disassemble the collecting box 10 to deal with the debris collected therein, thereby achieving the effect of automatic collection of broken glass parts, without the need for manual cleaning and collection by personnel, thereby reducing the labor intensity and danger of personnel and the cleaning time, and effectively improving the convenience of use and the efficiency of pressure measurement.

[0031] Furthermore, the driving member is composed of a motor 11 fixedly mounted on a side of the protection box 1 , and the output end of the motor 11 passes through the protection box 1 and is connected to a shaft rod 3 .

[0032] Specifically, when collecting component fragments, the motor 11 can drive the shaft 3 to rotate, thereby driving the carrier shell 2 to rotate and tilt at a certain angle, and pouring out the fragments inside for collection.

[0033] Furthermore, the moving mechanism includes a one-way screw 12 rotatably connected between the two sides of the inner wall of the protective box 1, a guide rod 13 fixedly installed between the two sides of the inner wall of the protective box 1 and located on both sides of the one-way screw 12, a mounting plate 14 threadedly connected to the surface of the one-way screw 12 and sliding with the guide rod 13, and a power part arranged on one side of the protective box 1.

[0034] The power part is composed of a second motor 15 fixedly mounted on one side of the protection box 1 , and the output end of the second motor 15 passes through the protection box 1 and is connected to the one-way screw 12 .

[0035] Specifically, during the pressure measurement process, the one-way screw 12 is driven to rotate by the motor 2 15, so that the mounting plate 14 drives the pressure measuring mechanism to move laterally along the surface of the guide rod 13, thereby achieving the effect of movement and adjustment of the pressure measuring mechanism, facilitating the pressure measuring mechanism to detect different positions of components, effectively improving the flexibility and range of pressure measurement, and being able to make the detection effect more accurate by detecting multiple positions.

[0036] Furthermore, the pressure measuring mechanism includes a hydraulic cylinder 16 fixedly installed on the bottom of the mounting plate 14, a pressure head 17 fixedly connected to the output end of the hydraulic cylinder 16, a groove opened at the bottom of the pressure head 17, a pressure sensor fixedly installed in the groove, and a display screen 18 fixedly installed on one side of the protective box 1, wherein the pressure sensor and the display screen 18 are electrically connected.

[0037] Specifically, when measuring pressure, the hydraulic cylinder 16 drives the pressure head 17 to move downward to contact the parts, and the pressure sensor detects the downward pressure. At the same time, the downward pressure data is transmitted to the display screen 18 for display, which is convenient for personnel to watch. Therefore, the pressure head 17 and the pressure sensor cooperate to achieve the purpose of pressure detection of parts.

[0038] Furthermore, the clamping mechanism includes a clamping cylinder 19 symmetrically fixedly mounted on two sides of the carrier shell 2 and two clamping plates 20 symmetrically arranged on the carrier shell 2 , and the output end of the clamping cylinder 19 passes through the carrier shell 2 and is connected to the clamping plates 20 .

[0039] Specifically, after the parts are placed in the carrier shell 2, the clamping cylinder 19 drives the two clamping plates 20 to move relatively close to each other, so that the clamping plates 20 contact and clamp the parts, thereby achieving the effect of fixing the parts, preventing the parts from shifting during pressure measurement, and ensuring the stability of pressure measurement.

[0040] Embodiment 2

[0041] Based on the first embodiment, the present embodiment includes: an auxiliary support mechanism, which is arranged in the protective box 1, for auxiliary supporting the carrier shell 2, and includes a shell 21 fixedly mounted on the inner bottom wall of the protective box 1 and located below the carrier shell 2, a bidirectional screw 22 rotatably connected between the two sides of the inner wall of the shell 21, two support blocks 23 symmetrically threadedly connected to the surface of the bidirectional screw 22 and sliding with the shell 21, and a motor 24 fixedly mounted on one side of the shell 21, the output end of the motor 24 passes through the shell 21 and is connected to the bidirectional screw 22, and the support block 23 is in contact with the carrier shell 2.

[0042] The technical solution provided by this embodiment is: when measuring pressure, the bidirectional screw 22 is driven to rotate by the motor three 24, so that the two support blocks 23 move closer to each other in the shell 21, so that they are in contact with the bottom of the carrier shell 2, thereby achieving the function of auxiliary support for the carrier shell 2, avoiding damage to the carrier shell 2 due to long-term use, and effectively improving the stability of the carrier shell 2. When collecting parts fragments, the bidirectional screw 22 is driven by the motor three 24 to reverse, so that the support blocks 23 move away from each other and separate from the carrier shell 2, to prevent interference with the rotation of the carrier shell 2.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
