Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a vibration test bench for radiators. Background Technology

[0002] In the present technology, radiators are widely used in the fields of machinery, industrial manufacturing, electronics and electrical appliances, and vehicle industry. Radiators mainly achieve the purpose of cooling the internal parts of the machine through the principle of heat exchange. Radiators are indispensable equipment in modern industry and life, driving the development of various fields such as electronics, automobiles, and energy. Especially in the field of vehicle technology, radiators are often used to cool the engine and reduce the engine temperature. In the present technology, the specific manufacturing and installation of radiators are carried out by welding and fastening the connecting components. However, in actual use, radiators are often in a vibrating environment. Therefore, in order to ensure the manufacturing quality of radiators, the present technology requires vibration testing of radiators.

[0003] In the existing technology, the vibration test of radiators is a special equipment used to simulate the vibration environment that radiators are subjected to during transportation, installation and use, in order to detect their structural strength, sealing performance, connection reliability and other performance. This plays a key role in the research and development, production and quality inspection of radiators.

[0004] In the existing technology, the common method of vibration test benches for radiators is to use mechanical equipment to drive the radiator to vibrate. Commonly used equipment includes mechanical vibration test benches and hydraulic vibration test benches. Mechanical vibration test benches generate reciprocating vibration through eccentric wheel or cam structure, which is suitable for low-frequency, high-load scenarios, such as large industrial radiators and car water tanks. They are relatively inexpensive but have a narrow frequency range. Hydraulic vibration test benches, on the other hand, are driven by hydraulic pressure and can generate large amplitude and large thrust. They are suitable for heavy radiators, such as aircraft engine radiators and large transformer radiators, and can simulate extreme impact vibrations.

[0005] Existing vibration test benches for radiators, such as the "Radiator Vibration Test Bench" disclosed in Publication No. CN214702680U, employ a lifting mechanism that drives the platform to reciprocate up and down, effectively simulating the impact and vibration effects on the radiator under extreme environments, and verifying product quality through testing. Another example is the "Vibration Test Fixture and Vibration Test System" disclosed in Publication No. CN211291925U, where the radiator is mounted on a vibration test bench using a vibration test fixture. This fixture includes a platform with multiple first oblong holes for engaging with mounting holes on the bottom of the radiator. This design allows for convenient and stable clamping of the radiator under test, and is simple in structure and easy to operate.

[0006] The above technical solutions all use reciprocating vibration to conduct vibration tests on radiators. However, the existing technical structure also has certain drawbacks. Most vibration test benches for radiators in the existing technology only use unidirectional vibration tests. For example, the above technical solutions only use vertical vibration to complete the experiment, or only complete the transverse vibration test, and cannot perform vibration tests in other directions. Therefore, the test structure is not very accurate and cannot effectively realize multi-directional vibration tests to provide accurate experimental results. The overall structural design is not reasonable enough.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a radiator vibration test bench with a reasonable structure that can provide vibration tests in two directions. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a vibration testing bench for radiators; the technical solution is as follows:

[0009] A vibration test bench for radiators includes a fixed table, a first vibration table, and a second vibration table. The first vibration table is mounted on the fixed table in a left-right sliding manner. A first reciprocating mechanism is installed on the left or right side of the fixed table. The main shaft of the first reciprocating mechanism is fixed on the first vibration table. The first reciprocating mechanism drives the first vibration table to vibrate left and right in a reciprocating manner.

[0010] The second vibration table is mounted on the first vibration table in a sliding manner, and a second reciprocating mechanism is installed on the front or rear side of the fixed table. The main shaft of the second reciprocating mechanism is detachably mounted on the second vibration table, and the second reciprocating mechanism drives the second vibration table to vibrate back and forth.

[0011] The radiator to be tested for vibration is fixed on the second vibration table. The radiator reciprocates back and forth through the second vibration table. When the second vibration table reciprocates, the first vibration table is fixed and the first reciprocating mechanism is closed. When the first vibration table reciprocates left and right under the drive of the first reciprocating mechanism, the main shaft of the second reciprocating mechanism is disassembled from the second vibration table and fixed to the second vibration table.

[0012] Furthermore, the fixed platform is provided with at least two first sliding grooves in the left and right directions, and the first vibration platform is provided with a first slider corresponding to the position of the first sliding groove. The first slider is correspondingly embedded in the first sliding groove, thereby slidingly mounting the first vibration platform on the fixed platform. The main shaft of the first reciprocating mechanism is fixed to the side wall of the first vibration platform, realizing the left and right movement of the first vibration platform.

[0013] Furthermore, the first vibration table is provided with a mounting groove in the front-to-back direction, and the second vibration table is correspondingly disposed in the mounting groove. The mounting groove is provided with a second sliding groove in the front-to-back direction.

[0014] Furthermore, the upper surface of the second vibration table is flush with the upper surface of the first vibration table.

[0015] Furthermore, pin holes are provided on both sides of the mounting groove of the first vibration table, and detachable fixing pins are installed in the pin holes. The distance between the two pin holes is consistent with the width of the second vibration table. When the main shaft of the second reciprocating mechanism is disassembled, the second vibration table is moved to the position between the two pin holes of the mounting groove, and the second vibration table is fixed in the mounting groove by installing fixing pins in the pin holes of the two sides.

[0016] Furthermore, the spindle end of the second reciprocating mechanism is provided with a mounting plate, which has mounting holes. The side wall of the second vibration table is provided with corresponding mounting holes. When the mounting plate and the mounting holes are aligned, they can be detached and installed using fasteners.

[0017] Furthermore, a mounting plate with mounting holes is provided at the bottom of the radiator, and a corresponding mounting hole is provided on the upper surface of the second vibration table. When the mounting plate at the bottom of the radiator corresponds to the mounting hole, the radiator can be detachably mounted on the second vibration table by fasteners.

[0018] Furthermore, a hinge seat is also installed on the second vibration table, and a hinge plate is installed on the hinge seat. The other end of the hinge plate is provided with a mounting hole, and the two side frame plates of the radiator are provided with corresponding mounting holes. When the mounting holes of the hinge plate correspond to the mounting holes on the second vibration table, the radiator is fixed in place by fasteners.

Detailed Implementation

[0030] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] like Figure 1As shown, a vibration test bench for radiators includes a fixed table 3, a first vibration table 1, and a second vibration table 2. The first vibration table 1 is mounted on the fixed table 3 in a left-right sliding manner. A first reciprocating mechanism 101 is mounted on the left or right side of the fixed table 3. The main shaft of the first reciprocating mechanism 101 is fixed on the first vibration table 1. The first reciprocating mechanism 101 drives the first vibration table 1 to vibrate left and right.

[0032] The second vibration table 2 is mounted on the first vibration table 1 in a sliding manner, and a second reciprocating mechanism 201 is installed on the front or rear side of the fixed table 3. The main shaft of the second reciprocating mechanism 201 is detachably mounted on the second vibration table 2, and the second vibration table 2 is driven to reciprocate back and forth through the second reciprocating mechanism 201.

[0033] like Figure 2 As shown, the radiator 4 to be tested for vibration is fixed on the second vibration table 2. The radiator 4 is reciprocated back and forth by the second vibration table 2. When the second vibration table 2 is reciprocating, the first vibration table 1 is fixed and the first reciprocating mechanism 101 is closed. When the first vibration table 1 is driven by the first reciprocating mechanism 101 to reciprocate left and right, the main shaft of the second reciprocating mechanism 201 is disassembled from the second vibration table 2 and correspondingly fixed to the second vibration table 2. The second vibration table 2 and the radiator 4 on the second vibration table 2 follow the first vibration table 1 to complete the left and right reciprocating vibration.

[0034] The fixed platform 3 is provided with at least two first sliding grooves 102 in the left and right directions, and the first vibration table 1 is provided with a first slider 103 corresponding to the position of the first sliding groove 102. The first slider 103 is correspondingly embedded in the first sliding groove 102, thereby sliding the first vibration table 1 on the fixed platform 3. The main shaft of the first reciprocating mechanism 101 is fixed to the side wall of the first vibration table 1, so as to realize the left and right movement of the first vibration table 1.

[0035] The first vibration table 1 is provided with a mounting groove 5 in the front-to-back direction. The second vibration table 2 is correspondingly set in the mounting groove 5, and the mounting groove 5 is correspondingly provided with a second sliding groove 202 in the front-to-back direction. The lower end face of the second vibration table 2 is provided with a second slider 203 that is adapted to the second sliding groove 202. When the second vibration table 2 is set in the mounting groove 5, the second slider 203 is correspondingly embedded in the second sliding groove 202, thereby enabling the second vibration table 2 to move in the front-to-back direction.

[0036] The upper surface of the second vibration table 2 is flush with the upper surface of the first vibration table 1.

[0037] like Figure 3 and Figure 4As shown, the mounting groove 5 of the first vibration table 1 is provided with pin holes 6 on both sides, and a detachable fixing pin 7 is installed in the pin holes 6. The distance between the two pin holes 6 is the same as the width of the second vibration table 2. When the main shaft of the second reciprocating mechanism 201 is disassembled, the second vibration table 2 is moved to the position between the two pin holes 6 on both sides of the mounting groove 5. By installing the fixing pin 7 in the two pin holes 6 on both sides, the second vibration table 2 is fixed in the mounting groove 5.

[0038] like Figure 5 As shown, the spindle end of the second reciprocating mechanism 201 is provided with a mounting plate 8, and the mounting plate 8 is provided with mounting holes 9. The side wall of the second vibration table 2 is provided with mounting holes 9 corresponding to the position. When the mounting plate 8 and the mounting holes 9 are in the same position, they can be detached and installed by fasteners 10.

[0039] like Figure 1 As shown, a mounting plate 8 is provided at the bottom of the radiator 4, and mounting holes 9 are provided on the mounting plate 8. The upper end face of the second vibration table 2 is provided with corresponding mounting holes 9. When the mounting plate 8 at the bottom of the radiator 4 corresponds to the mounting holes 9, the radiator 4 can be detachably mounted on the second vibration table 2 by fasteners 10.

[0040] The second vibration table 2 is also equipped with a hinge seat 11, and a hinge plate 12 is installed on the hinge seat 11. The other end of the hinge plate 12 is provided with a mounting hole 9, and the two side frames of the radiator 4 are provided with corresponding mounting holes 9. When the mounting holes 9 of the hinge plate 12 correspond to the mounting holes 9 on the second vibration table 2, the radiator 4 is fixed by fasteners 10.

[0041] The vibration test bench for the radiator 4 in this device operates on the same principle as that in the prior art. It simulates vibration by using a mechanical cam structure or eccentric wheel structure, as well as hydraulic, pneumatic, or electric equipment as in the prior art to generate reciprocating vibration in the radiator 4. The principle is the same. The first reciprocating mechanism 101 and the second reciprocating mechanism 201 in this device can both be implemented using existing technology or hydraulic equipment. Therefore, the specific structure of the first reciprocating mechanism 101 and the second reciprocating mechanism 201 is not described in detail in this device. However, both reciprocating mechanisms are prior art and can be understood by those skilled in the art. In this device, a fixed platform 3 is first set up, which is not movable. The first vibration platform 1 is movably placed on the fixed platform 3, and the second vibration platform 2 is also movably placed on the first vibration platform 1. The movement directions of the first vibration platform 1 and the second vibration platform 2 are perpendicular. The movement direction of the first vibration platform 1 is left and right, and the movement direction of the second vibration platform 2 is front and back. Therefore, after the radiator 4 is fixed on the second vibration platform 2, the reciprocating vibration test of the radiator 4 in the front and back direction can be realized by the individual reciprocating movement of the second vibration platform 2. The left and right reciprocating movement of the first vibration platform 1 can realize the left and right reciprocating vibration of the radiator 4. Therefore, the design of this device can realize the reciprocating vibration test of the radiator 4 in two directions. The structural design is very ingenious and reasonable. Therefore, based on the above principle, this device is specifically designed with a technical structure that can move both left and right and front and back.

[0042] In this device, the fixed platform 3 is fixed in place. Firstly, two transverse first sliding grooves 102 are set on the fixed platform 3. Correspondingly, two first sliders 103 are set on the lower end face of the first vibration table 1. After the first sliding grooves 102 are embedded in the first sliders 103, they are then fixedly connected to the side wall of the first vibration table 1 via a first reciprocating mechanism 101 mounted on the outside. This allows the first vibration table 1 to reciprocate in the left-right direction. In this technical solution, the design of the sliding grooves and sliders are common sliding connection settings in the prior art, which already exist in the prior art and therefore are not described in detail. Simultaneously, this device also provides a front-to-back mounting groove 5 on the upper end face of the first vibration table 1, while the second vibration table... The second vibration table 2 is correspondingly set in the mounting groove 5. In this device, to reduce the overall space and size occupied by the structure, the mounting groove 5 is provided, and the second vibration table 2 is directly placed in the mounting groove 5, with the upper surface of the second vibration table 2 flush with the upper surface of the first vibration table 1. This reduces the overall height and size accordingly. Simultaneously, a second sliding groove 202 and a second slider 203 in the front-to-back direction are provided in the mounting groove 5. This design of the sliding groove and slider is common in existing technology. Therefore, the second vibration table 2 can reciprocate in the front-to-back direction within the mounting groove 5 of the first vibration table 1, with the cooperation of the first slider 103 and the second sliding groove 202. However, it has… The reciprocating movement of the body is achieved through the second reciprocating mechanism 201. The main shaft connection of the second reciprocating mechanism 201 needs to be designed to be detachable, allowing for reciprocating vibration testing in two directions. In practical use, the radiator 4 is fixed to the second vibration table 2, the main shaft of the second reciprocating mechanism is mounted and fixed to the second vibration table 2, and the first reciprocating mechanism 101 is closed, fixing the position of the first vibration table 1. Then, the second reciprocating mechanism 201 is activated, causing the second vibration table 2 to vibrate in the front-to-back direction, thus allowing the radiator 4 to vibrate in the second vibration table 2. After the reciprocating vibration test on the platform 2 is completed, the second reciprocating mechanism 201 is closed, and the main shaft of the second reciprocating mechanism 201 is disassembled from the second vibration platform 2. Then, the second vibration platform 2 is fixed in the mounting groove 5 of the first vibration platform 1 through the cooperation of the pin hole 6 and the fixing pin 7 shaft. At this time, since the restriction of the second reciprocating mechanism 201 is no longer present, the first reciprocating mechanism 101 can be opened to drive the first vibration platform 1, the second vibration platform 2 in the mounting groove 5 of the first vibration platform 1, and the radiator 4 on the second vibration platform 2 to move back and forth in the left and right directions, so as to realize the reciprocating vibration test of the radiator 4 in the left and right directions. Therefore, the vibration test in two directions can be completed.

[0043] In addition, the specific installation of the radiator 4 in this device is also a technical problem to be solved. In the prior art, the bottom of the radiator 4 usually needs to be provided with a mounting plate 8, which is used to install it on the vehicle. This device uses the mounting plate 8 itself to install the radiator 4. In this device, mounting holes 9 are provided on the second vibration table 2. After the mounting plate 8 at the bottom of the radiator 4 is aligned with the mounting holes 9, the radiator 4 can be fixed by fasteners 10. At the same time, the radiator 4 can also be disassembled. However, it may not be enough to just fasten it with the mounting plate 8 at the bottom. Therefore, this device also provides a hinge seat 11 and a hinge plate 12. The hinge plate 12 is provided with mounting holes 9. After the mounting holes 9 on the frame plates on both sides of the radiator 4 are aligned, the corresponding installation can be achieved by fasteners 10. Then the radiator 4 can be fixed more stably on the second vibration table 2. In addition, the connection between the main shaft of the second reciprocating mechanism 201 and the side wall of the second vibration table 2 in this device can also be detached and installed by the cooperation of the mounting plate 8 and the mounting hole 9, which is a common structural installation in the prior art. In addition, regarding the fixing of the second vibration table 2 in this device, after the second vibration table 2 is disassembled from the main shaft of the second reciprocating mechanism 201, the second vibration table 2 needs to be fixed in the mounting groove 5. This device uses a structure of pin hole 6 and fixing pin 7 to fix the second vibration table 2. Afterwards, the fixing pin 7 can be removed to ensure the flexibility of the second vibration table 2.

[0044] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
