Description

Technical Field

[0001] The utility model relates to the technical field of compressor detection, in particular to a compressor vibration test tool. Background Art

[0002] With the continuous development of modern industry, especially the rapid growth of the automotive industry, compressors have been widely used in many key areas such as automotive refrigeration, air conditioning, and related air compression systems. The performance and reliability of a compressor are directly related to the operating efficiency and stability of the entire system. Vibration testing is an extremely important part of the compressor's research and development, production, and quality inspection process. It is irreplaceable for evaluating the compressor's structural strength, operational stability, and reliability. Vibration testing can simulate the vibration conditions of the compressor in an actual operating environment and test its structural stability, component reliability, and overall performance to ensure that it meets design requirements. The compressor vibration test fixture is a key tool for conducting this test. Its design and performance are directly related to the accuracy and effectiveness of the vibration test.

[0003] Currently, existing vibration test fixtures, such as the one disclosed in CN116519247A, include a vibration table and a frame. The vibration table is equipped with multiple fixed positions for mounting test specimens. One end of the frame is detachably connected to some of the fixed positions, forming a clamping space within the frame to accommodate the test specimens. The frame is equipped with two first fastening mechanisms, each of which is equipped with two second fastening mechanisms. The first fastening mechanism is used to clamp the test specimen and can be adjusted and locked in the X direction. The second fastening mechanism can be adjusted in the Y direction to adjust the clamping force. Although this technical solution has certain versatility and can be applied to different test samples, it has obvious shortcomings in practical applications: on the one hand, despite its wide applicability, it is difficult to accurately simulate the actual installation status of the sample, resulting in a large deviation between the test results and the actual situation; on the other hand, when installing the test sample, this technical solution requires first removing the frame from the vibration table, and then installing the test sample on the vibration table. After the test sample is in place, the frame must be installed back on the vibration table. This installation process is quite cumbersome and significantly reduces the test efficiency. Utility Model Content

[0004] The utility model aims to provide a compressor vibration test fixture to achieve accurate simulation of the actual installation state of the compressor, improve the accuracy and reliability of the test results, and at the same time, simplify the installation process and improve test efficiency.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a compressor vibration test tool, including a vibration table and a belt, the vibration table is detachably connected to a bracket, a compressor mounting unit and a belt tensioner mounting unit are provided on the bracket, the compressor mounting unit is used to install the compressor, the belt tensioner mounting unit is installed on the belt tensioner, and the belt is installed on the belt tensioner and the compressor belt mounting pulley.

[0006] The beneficial effects of this solution are as follows: Through the rational arrangement of the vibration table, bracket, compressor mounting unit, and belt tensioner mounting unit, and the use of a belt to connect the compressor belt mounting pulley and belt tensioner, this technical solution can highly reproduce the compressor's installation state on an actual vehicle. This design takes into account the actual working mode of the compressor in the automotive system, allowing the vibration test to more realistically reflect the compressor's actual operation, thereby making the test results more accurate and reliable, providing more valuable data support for compressor performance evaluation and optimization; at the same time, it has the advantage of high vibration transmission efficiency.

[0007] Compared to existing technologies, this tool eliminates the need for tedious operations such as disassembling and reinstalling the frame during testing. The compressor can be directly installed on the compressor mounting unit, and the belt tensioner can be easily installed on the belt tensioner mounting unit. The belt connection completes the installation. This design greatly simplifies the installation process, reduces installation time and labor costs, significantly improves testing efficiency, and enables faster acquisition of test results, accelerating the development and quality inspection of compressors.

[0008] The tooling provided by this technical solution has significant advantages, which are mainly reflected in the following aspects:

[0009] First, its wide applicability. This tool can be used not only for vibration testing of compressors but also for other structures with similar installation locations. This versatility greatly expands the tool's application range, enabling it to be effective in a variety of scenarios.

[0010] Secondly, the sophisticated structural design. The tooling's structure is both rational and simple, making assembly between components easy and simple, without complex procedures or excessive technical requirements. This feature offers significant advantages in practical use, making both disassembly and installation extremely convenient, saving operators considerable time and effort and significantly improving work efficiency.

[0011] Third, the tooling's cost-effectiveness is a key advantage. The tooling's simple design makes it easy to manufacture, eliminating the need for complex processes and high-end equipment. This not only reduces resource investment and costs during the manufacturing process, but also creates favorable conditions for large-scale production and widespread adoption. This effectively highlights the tooling's value and competitiveness in practical applications, giving it a significant advantage in the market.

[0012] Furthermore, the compressor mounting unit includes a sample mounting portion, the compressor is mounted on the sample mounting portion, and the sample mounting portion can be adjusted in a horizontal direction of the bracket and locked.

[0013] The beneficial effects of this solution are: since the sample mounting portion of this technical solution can adjust its position in the horizontal direction of the bracket and can be locked, the installation position of the compressor can be adjusted laterally, so that the tooling provided by this technical solution can be applicable to compressors of different models and sizes, has universality, and saves the development cost of the tooling.

[0014] Furthermore, the sample mounting portion includes a No. 1 mounting plate and a No. 2 mounting plate, both of which can be adjusted in the horizontal direction of the bracket and locked.

[0015] The beneficial effects of this solution are as follows: compared with setting the sample mounting portion as a whole mounting plate, this technical solution has the following advantages:

[0016] (1) Mounting the compressor on mounting plates 1 and 2 provides two independent and adjustable support points for the compressor. This multi-point support method can clamp the compressor more firmly. During the vibration test, the compressor may be subjected to vibration forces of various directions and intensities. The two mounting plates can share these forces from different positions, effectively preventing the compressor from shaking or displacement, and ensuring its stability during the test.

[0017] (2) Compressors of different models vary in shape and size. The independent adjustability of mounting plates 1 and 2 allows them to better adapt to these changes. For compressors with irregular shapes, the two mounting plates can be adjusted separately according to their specific shapes to achieve the best fit and support effect. For compressors of different sizes, the distance and position relationship between the two mounting plates can also be flexibly adjusted to meet installation requirements, thereby greatly improving the adaptability of the tooling to different compressors.

[0018] (3) When conducting vibration tests on compressors, it is often necessary to install and disassemble the compressor. The design of mounting plate 1 and mounting plate 2 makes this process more convenient. Compared with a single mounting plate, two independent mounting plates provide more flexible operating space.

[0019] Furthermore, both the No. 1 mounting plate and the No. 2 mounting plate are provided with a vertical No. 1 strip hole.

[0020] The beneficial effect of this solution is that due to the setting of the No. 1 strip hole, this technical solution can vertically adjust the installation position of the compressor, so that the tooling can adapt to compressors of different models and sizes and has universality.

[0021] Furthermore, the belt tensioner installation unit includes a fixing plate, the fixing plate is fixedly connected to the bracket, and the belt tensioner is installed on the fixing plate.

[0022] The beneficial effect of this solution is that the technical solution improves the stability of the belt tensioner by installing the belt tensioner on the fixed plate.

[0023] Furthermore, a second strip hole is provided on the fixing plate, and the belt tensioning wheel is slidably arranged on the second strip hole, and the belt tensioning wheel can be locked.

[0024] The beneficial effect of this solution is that, due to the provision of the No. 2 strip hole, this technical solution allows for lateral adjustment of the belt tensioner's installation position. In actual operation, this adjustability allows the belt tensioner to be precisely adjusted to the appropriate position, effectively tightening the belt. This design closely matches the actual installation state of the compressor on a real vehicle, where the belt is in a taut state. Through such precise simulation, the authenticity and reliability of the vibration test can be greatly improved, ensuring that the test results more accurately reflect the compressor's performance in the actual operating environment.

[0025] Furthermore, a connecting plate is fixedly connected to one side of the fixing plate close to the compressor mounting unit. A positioning hole is provided on the connecting plate. A positioning piece is provided in the positioning hole. The positioning piece can contact and press the belt tensioner.

[0026] The beneficial effects of this solution are as follows: due to the provision of the positioning member, this technical solution can, on the one hand, keep the belt in a taut state at all times, and on the other hand, improve the stability of the belt tensioner.

[0027] Furthermore, the positioning hole is a threaded hole, the positioning piece is a positioning bolt, and the positioning piece is threadedly connected to the positioning hole.

[0028] The beneficial effects of this solution are as follows: this technical solution sets the positioning hole as a threaded hole, the positioning part as a positioning bolt, and the belt tensioner is tightened by the positioning bolt, so that the belt is always in a taut state, providing the possibility of accurately simulating the actual installation state of the actual vehicle, thereby greatly improving the authenticity and reliability of the vibration test.

[0035] Example

[0036] like Figure 1 A vibration test fixture for a compressor 17 shown includes a vibration table 1, a belt 2, a compressor mounting unit, and a belt tensioner mounting unit.

[0037] like Figure 1 and Figure 2 As shown, a bracket 3 is mounted on the upper side of the vibration table 1 by bolts, and two No. 3 strip holes 4 are opened on the front side of the bracket 3 along its horizontal direction. The compressor mounting unit is arranged on the front side of the bracket 3. Specifically, the compressor mounting unit includes a No. 2 locking piece 5, a No. 3 locking piece 6 and a sample mounting part. The number of No. 2 locking pieces 5 and No. 3 locking pieces 6 are both four. The sample mounting part is composed of a No. 1 mounting plate 7 and a No. 2 mounting plate 8. The No. 1 mounting plate 7 is located on the left side of the No. 2 mounting plate 8. The No. 1 mounting plate 7 and the No. 2 mounting plate 8 are both mounted on the bracket 3 through the No. 2 locking piece 5. The front sides of the No. 1 mounting plate 7 and the No. 2 mounting plate 8 are both provided with a vertical No. 1 strip hole 9. The compressor 17 is mounted on the No. 1 mounting plate 7 and the No. 2 mounting plate 8 through the No. 3 locking piece 6. Due to the setting of the No. 3 strip hole 4 and the No. 1 strip hole 9, the installation position of the compressor 17 can be flexibly adjusted in both the horizontal and vertical directions, so that the tooling provided by this technical solution can be widely applicable to compressors 17 of different models and various installation sizes, which greatly expands the application range of the tooling. At the same time, it can also effectively save the development cost of tooling and avoid the waste of resources in frequently developing special tooling for compressors 17 of different specifications.

[0038] like Figure 1 、 Figure 3 and Figure 4 As shown, the belt tensioner mounting unit is arranged on the right side of the bracket 3. The belt tensioner mounting unit is equipped with a belt tensioner 10. The belt 2 is mounted on the belt tensioner 10 and the belt mounting pulley of the compressor 17. The belt 2 can be tightened by the belt tensioner 10. A slider 11 is integrally formed on the left side of the belt tensioner 10. Specifically, the belt tensioner 10 mounting unit includes a fixing plate 12, a connecting plate 13, a positioning member 14 and a No. 1 locking member 15. The fixing plate 12 is welded to the right side of the bracket 3. The connecting plate 13 is integrally formed with the front side of the fixing plate 12. The right side of the fixing plate 12 is provided with a No. 2 strip hole 16. The slider 11 is slidably arranged in the No. 2 strip hole 16 and is mounted on the fixing plate 12 through the No. 1 locking member 15. The connecting plate 13 is provided with a positioning hole (in this embodiment, the positioning hole is a threaded hole). The positioning member 14 passes through the positioning hole to contact the front side of the belt tensioner 10 and press the belt tensioner 10, so that the belt 2 is tightened. Due to the provision of the No. 2 bar hole 16 and the positioning hole, the installation position of the belt tensioner 10 can be adjusted laterally. In actual operation, through this adjustability, the belt tensioner 10 can be accurately adjusted to the appropriate position, thereby effectively tightening the belt 2. This design is highly consistent with the actual installation state of the compressor 17 on the actual vehicle, that is, the belt 2 is in a tightened state. Through such precise simulation, the authenticity and reliability of the vibration test can be greatly improved, so that the test results can more accurately reflect the performance of the compressor 17 in the actual working environment. It should be noted here that the No. 1 locking member 15, the No. 2 locking member 5 and the No. 3 locking member 6 are all locking bolts in this embodiment, and the positioning member 14 is a positioning bolt. The positioning member 14 is threadedly connected to the connecting plate 13. This connection method ensures the stability and adjustability of the connection, and provides a guarantee for the stable operation of the entire tooling.

[0039] The specific implementation process is as follows:

[0040] The installation of the compressor 17 and the belt tensioner 10 includes the following steps:

[0041] (1) Pre-tighten the No. 1 mounting plate 7 and the No. 2 mounting plate 8 on the bracket 3 through the No. 2 locking piece 5. The No. 2 locking piece 5 is in an untightened state. Slide the No. 1 mounting plate 7 and the No. 2 mounting plate 8 on the No. 3 strip hole 4. After adjusting the No. 1 mounting plate 7 and the No. 2 mounting plate 8 to the appropriate position (the lateral distance between the No. 1 mounting plate 7 and the No. 2 mounting plate 8 is equal to the lateral distance between the mounting holes of the compressor 17; the belt mounting pulley of the compressor 17 is laterally aligned with the belt tensioning pulley 10), tighten the No. 2 locking piece 5.

[0042] (2) The belt tensioner 10 is pre-tightened on the fixed plate 12 through the No. 1 locking piece 15 so that the belt tensioner 10 can slide in the No. 2 strip hole 16.

[0043] (3) Pre-tighten the compressor 17 on the No. 1 mounting plate 7 and the No. 2 mounting plate 8 through the No. 3 locking piece 6. The No. 3 locking piece 6 is in an untightened state. Slide the compressor 17 on the No. 1 strip hole 9. After adjusting the compressor 17 to a suitable position (the belt mounting pulley of the compressor 17 is longitudinally aligned with the belt tensioning pulley 10), tighten the No. 3 locking piece 6.

[0044] (4) Install the belt 2 on the belt tensioner 10 and the belt mounting pulley of the compressor 17.

[0045] (5) Rotate the positioning member 14 in the threaded hole so that the positioning member 14 contacts and presses the belt tensioning pulley 10, thereby tightening the belt 2.

[0046] (6) Tighten the No. 1 locking piece 15 to fix the belt tensioner 10 on the fixing plate 12.
