Description

Technical Field

[0001] The utility model relates to the technical field of axial dynamic load testing, in particular to a testing tool and a testing system. Background Art

[0002] In many rotating equipment, especially those with heavy loads and high-speed rotation, structural components that can withstand axial thrust (such as high-thrust protectors or high-thrust bearings) are required to achieve effects such as reasonable distribution of thrust loads and avoid equipment damage. These structural components need to be tested for axial dynamic loads before leaving the factory to ensure that they have good performance.

[0003] Usually, the axial dynamic load test needs to be completed by a coaxially arranged cylinder and motor. Among them, the cylinder docks with the test component and applies axial pressure to it. The rotating shaft of the motor also needs to dock with the test component to output torque to drive the test component to rotate. In order to achieve the docking between the cylinder, the test component and the motor, the tester needs to hold the test component, dock it with the cylinder, and then further dock it with the motor. This manual operation method easily causes the cylinder, the test component and the motor to be not on the same axis, and the angle needs to be adjusted multiple times to ensure successful docking. When the test component is large in size or weight and cannot be lifted manually by a single person, it may even be necessary to use a crane or require the cooperation of multiple people, which takes up more resources and significantly affects the test efficiency.

[0041] Figure 1 This is a schematic diagram of the structure of the test tool provided in the embodiment of the present application. Figure 1 As shown, the test fixture includes: a frame 10 , a first mounting assembly 20 , a second mounting assembly 40 and a workpiece mounting assembly 60 .

[0042] The frame 10 is the main supporting structure of the entire test fixture, which extends along the axial direction x and has a suitable size and shape, and can provide and form a basic test work surface.

[0043] For ease of description, in the present invention, the rack 10 is roughly divided into a first area A1, a second area A2, and a test area A3. The first area A1, the test area A3, and the second area A3 are sequentially arranged along a first direction x. In other words, the first area A1 and the second area A2 are far away from each other in the first direction x, and the test area A3 is located between the first area A1 and the second area A2.

[0044] The first mounting assembly 20 is a combination of one or more structural components for carrying the torque output device 30. It is arranged in the first area A1 of the frame, and enables the torque output device 30 to be conveniently docked with the test workpiece.

[0045] In the present invention, the structure of the first mounting assembly 20 directly carrying and mounting the torque output device 30 can be referred to as a "mounting bracket". The mounting bracket 21 is designed to have a degree of freedom of movement in the axial direction, so that the torque output device 30 can reciprocate along the first direction relative to the frame to achieve docking and disassembly with the test workpiece.

[0046] The second mounting assembly 40 is a combination of one or more structural components for carrying the pressure output device 50. Different from the first mounting assembly 20, it is arranged in the second area A2 of the frame to enable the pressure output device 50 to dock with the test workpiece accurately and quickly.

[0047] In the present invention, the area of ​​the second mounting assembly 40 that carries the pressure output device 50 is referred to as an accommodation space. In the accommodation space, the second mounting assembly 40 provides a movable component for mounting the pressure output device 50. The movable component can rotate relative to the frame 10 around the first direction, so that the pressure output device 50 can also rotate accordingly.

[0048] The workpiece mounting assembly 60 is an assembly for carrying one or more structural components of a test workpiece and is placed in the test area A3 in the middle of the frame, thereby forming a test station for stably placing the test workpiece 70 .

[0049] Specifically, the test station is designed to have a height adjustment capability, and can move relative to the frame 10 along the second direction. In the present application, for the convenience of description, the direction perpendicular to the first direction x is referred to as the second direction y. Accordingly, the above-mentioned "height adjustment" refers to the position change in the second direction y.

[0050] In some embodiments, in order to meet the use requirements of test workpieces of different lengths and specifications, the frame 10 can be designed in a split type, formed by two or more independent components fixedly connected by one or more detachable connection methods such as fasteners.

[0051] For example, Figure 3 FIG. 1 shows a separate design rack 10 provided in an embodiment of the present application. Figure 3 As shown, the frame 10 may include: a first frame member 11 and a second frame member 12 fixedly connected by fasteners.

[0052] The structural design and size shape of the first frame member 11 and the second frame member 12 are not specifically limited here, and can be specifically determined according to the actual needs. The corresponding relationship between them and the above-mentioned first area, test area and second area can also be adjusted according to the actual situation.

[0053] For example, a first area A1 may be provided on a side of the first frame member 11 facing away from the second frame member 12 , a second area A2 may be provided on a side of the second frame member 12 facing away from the first frame member 11 , and a test area A3 may be provided on a side of the first frame member 11 facing the second frame member 12 .

[0054] Alternatively, the test area A3 may also be disposed on a side of the second frame member 12 facing the first frame member 11. In other embodiments, the test area A3 may also be formed by: a side of the first frame member 11 facing the second frame member 12 and a side of the second frame member 12 facing the first frame member 11.

[0055] In actual use, when the axial length of the test workpiece does not exceed the set upper limit, it can be directly placed on the test station and docked with the torque output device 30 and the pressure output device 50. When the axial length of the test workpiece is longer and exceeds the current test area length of the frame 10, the length of the test area can be extended by adding one or more additional structures after the first frame member 11 and the second frame member 12 are disassembled and separated, so that longer test workpieces can be smoothly accommodated and placed on the test station.

[0056] Of course, when the axial length of the test workpiece is significantly shorter, part of the additional structure in the first frame member 11 and / or the second frame member 12 can be omitted to reduce the length dimension of the test area so that the torque output device 30 and the pressure output device 40 can be smoothly docked.

[0057] Based on the test fixture provided by the embodiment of the utility model, the utility model further provides a test system. The test system installs a torque output device 30 on the first installation assembly 20 of the test fixture provided by one or more embodiments above, and installs a pressure output device 50 on the second installation assembly 40 to complete the axial dynamic load test.

[0058] The torque output device 30 is a mechanical device capable of generating torque, which can convert input energy (e.g., electrical energy, hydraulic energy, or pneumatic energy) into mechanical energy and output it in the form of shaft rotation, etc. Exemplarily, the torque output device 30 includes, but is not limited to, an electric motor that generates rotational motion based on the principle of electromagnetic induction.

[0059] The pressure output device 50 is a device capable of generating a desired axial pressure. It can generate a thrust or a pull along the axial direction x of the device through a specific power source, thereby generating a controllable axial pressure. Exemplarily, the pressure output device 50 includes but is not limited to: a hydraulic cylinder that generates axial pressure using hydraulic oil and a pneumatic cylinder that generates axial pressure using compressed air.

[0060] In the actual axial dynamic load test process, on the one hand, the interval between the test station and the frame can be adjusted so that the workpiece 70 to be tested and the pressure output device 50 are kept on the same axis.

[0061] Subsequently, a coupling is put on one end of the workpiece 70 to be tested, and the workpiece 70 is docked with the pressure output device 50. When docking with the pressure output device 50, the operator can hold the workpiece 70 to be tested with one hand, and use the other hand to rotate the pressure output device 50 around the first direction to adjust the position, so that the pressure output device 50 is docked with the workpiece 70 to be tested.

[0062] On the other hand, the rotation axis of the torque output device 30 and the workpiece 70 to be measured can be kept on the same axis by adjusting the interval between the first mounting assembly 20 and the frame 10. Then, the torque output device 30 is pushed to move along the first direction, approach the workpiece 70 to be measured, and dock with the workpiece 70 to be measured.

[0063] In order to fully illustrate the inventive concept of the present utility model, at least one specific implementation of the first mounting assembly, the second mounting assembly and the workpiece mounting assembly is described below.

[0064] It should be noted that any of the following structural components can be freely combined to obtain different specific implementations unless the possibility of combination is explicitly excluded.

[0065] 1) Regarding the first installation component 20:

[0066] like Figure 4 As shown, the first mounting assembly 20 may include: a mounting bracket 21 , a guide mechanism 22 and a first height adjustment mechanism 23 .

[0067] The mounting bracket 21 is a structural component directly and rigidly connected to the torque output device 30, and may have a size, shape, and structure that matches the torque output device 30. For example, Figure 2 As shown, when the torque output device 30 adopts a motor 31 of a typical structure and a gearbox 32 used in conjunction therewith, the mounting bracket 21 can be roughly L-shaped, consisting of two substantially vertically arranged plate-like structures. One of the plate-like structures can be provided with a notch, and the torque output shaft of the gearbox 32 passes through the notch and is arranged toward the test area.

[0068] The guide mechanism 22 is a mechanical device for determining the motion trajectory of a component in a mechanical system. It is designed to limit the degree of freedom of the component in a non-designed direction so that the component can only move along a preset trajectory.

[0069] In this embodiment, in order to meet the docking and disassembly requirements between the torque output device 30 and the test workpiece, the preset trajectory can be designed as a straight path extending along the axial direction, so that the torque output device 30 can approach and move away from the test workpiece along the axial direction, thereby completing the docking and disassembly accordingly.

[0070] For example, Figure 2 and Figure 4As shown, the guide mechanism 22 may be composed of a linear guide rail 221 and a plurality of moving parts 222. The linear guide rail 221 extends along the axis direction to form a track with two ends closed. The moving parts 222 are placed and accommodated inside the track formed by the linear guide rail 221. Through the cooperation between the linear guide rail 221 and the moving parts 222, the moving parts 222 can be guided to reciprocate along the first direction x.

[0071] The first height adjustment mechanism 23 is a structural component for achieving height adjustment of the first mounting assembly, and is disposed between the guide mechanism 22 and the frame 10, and can adjust the interval between the guide mechanism 22 and the frame 10 along the second direction, thereby achieving height adjustment of the first mounting assembly.

[0072] The first height adjustment mechanism 23 can be any suitable type of adjustment mechanism with self-locking characteristics (no position change due to gravity or load in the absence of external force) according to actual needs, such as a lifting mechanism based on a rotating screw, or a pressure lifting mechanism based on hydraulic / pneumatic control.

[0073] For details, please continue to refer to Figure 4 In order to better support the mounting bracket 21, the linear guide rails 221 can be arranged in pairs, and the moving parts 222 are arranged in four, evenly distributed on the mounting bracket 21. Each of the four moving parts 222 forms a group of two, which are respectively accommodated in the track of the linear guide rails 221, and cooperate to form the above-mentioned guide mechanism.

[0074] More specifically, in order to match the two linear guide rails 221 , the rotary screw may include four first screws 231 and four matching first nuts 232 .

[0075] For each linear guide rail 221 , two first screw rods 231 are spaced apart and located at two ends of the linear guide rail in the first direction, and one end of the first screw rod 231 is fixedly connected to the linear guide rail 221 . Two first nuts 232 are threadedly connected to the two first screw rods 231 , respectively.

[0076] The first nut 232 is rotatably connected to the frame 10 . When the first nut 232 rotates relative to the frame 10 about the second direction, the first screw rod 231 can be driven to move relative to the frame 10 along the second direction, thereby achieving height adjustment of the linear guide rail 221 .

[0077] The spacing arrangement of the plurality of first nuts 231 and the first screw rods 232 can ensure the balanced force of the linear guide rail 221. It can be understood by those skilled in the art that, based on the same concept of balanced force, other numbers of first screw rods 231 and first nuts 232 thereof can be arranged according to the actual quantity, and are not limited to those shown in the drawings of the specification of the embodiment of the utility model.

[0078] 2) Regarding the second mounting assembly 40:

[0079] like Figure 5 As shown, the second mounting assembly 40 may be composed of a plurality of mounting units 41. Two adjacent mounting units 41 are spaced apart in the first direction of the frame 10, and can restrict the pressure output device 50 having a certain length on the frame 10 to prevent it from moving or falling off during use.

[0080] Specifically, each installation unit 41 may include: an installation base 411 , a fixing member 412 and a movable member 413 .

[0081] The mounting base 411 is a component connected to the rack 10. It serves as a joint point of the mounting unit on the rack and provides a mounting surface for the fixing member 412 to be installed.

[0082] The fixing member 412 is the main structure of the entire installation unit and is detachably connected to the installation base 411 to lock and fix the pressure output device 50 on the installation base 411 .

[0083] The movable part 413 is arranged on the side of the mounting base 411 away from the frame, and can be in rolling contact with the surface of the pressure output device 50. In this embodiment, it is called a "movable part" because it has the ability to move freely relative to the mounting base 411. By additionally providing the movable part 413, the pressure output device 50 installed in the second mounting assembly 40 can be rotated around the first direction.

[0084] For example, please refer to Figure 5 The pressure output device 50 may be a roughly cylindrical oil cylinder. Accordingly, the fixing member 412 may be a U-shaped bolt with one end open. It is fixed to the mounting surface of the mounting base 411 through a threaded connection, and can surround the outer circumference of the cylindrical oil cylinder to lock the pressure output device 50 on the mounting base 411.

[0085] Specifically, the moving part 222 in the first installation assembly and the movable part 413 in the second installation assembly can both use universal wheels.

[0086] 3) For the workpiece mounting assembly 60:

[0087] like Figure 6 As shown, the workpiece mounting assembly 60 may include: a support frame 61 and a second height adjustment mechanism 62 .

[0088] The support frame 61 is a component for supporting the test workpiece. It has a shape that matches the outer surface of the test workpiece and can form a test station for the test workpiece to be placed. For example, the support frame 61 can be roughly semicircular and match the cylindrical test workpiece.

[0089] The second height adjustment mechanism 62 is a structural component for realizing height adjustment of the test station, which is arranged between the support frame 61 and the frame 10, and enables the test station to move relative to the frame 10 in the second direction by changing the interval between the support frame 61 and the frame 10.

[0090] It should be noted that, in the present application, the first and second in "first height adjustment mechanism" and "second height adjustment mechanism" are only used to distinguish the different positions where the height adjustment structures are set, and are not used to limit the specific implementation of the height adjustment mechanism.

[0091] For example, the second height adjustment mechanism 62 can choose to use the same lifting mechanism based on a rotating screw as the first height adjustment mechanism 23. Alternatively, the second height adjustment mechanism can also choose to use a different structural setting from the first height adjustment mechanism, depending on the needs of the actual use scenario.

[0092] Please continue reading Figure 6 The second height adjustment mechanism can be composed of a second screw rod 621 and a second nut 622 .

[0093] The second screw rod 621 is arranged along the height direction y, and has an external thread formed on its surface. The support frame 61 is connected to one end of the second screw rod 621 and can move with the second screw rod 621 .

[0094] The second nut 622 is a component with a hole, and the inner wall of the hole is provided with an internal thread matching the external thread of the second screw rod 621. The second nut 622 is rotatably connected to the frame 10 and can rotate relative to the frame 10 around the second direction.

[0095] The threaded engagement between the second screw 621 and the second nut 622 can convert the rotational motion of the nut into a linear motion along the height direction. Thus, when the second nut 622 rotates relative to the frame 10 about the second direction, the second screw 621 can be driven to move relative to the frame along the second direction, thereby changing the height of the support frame 61.

[0096] In summary, the test fixture provided by the embodiment of the utility model has the advantages of simple structure and low cost, and can realize the rapid disassembly and assembly between the test workpiece and the motor and / or the oil cylinder, and can also realize the free adjustment of the height. Furthermore, by using a separate design of the frame, it can be applied to test workpieces of various specifications.

[0097] The above contents are further detailed descriptions of the present invention in combination with specific / preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
