Description

Technical Field

[0001] The present invention relates to an adapter with a temperature control function and an integrated environmental test device. Background Art

[0002] A single environmental test equipment can no longer meet the reliability assessment of test samples. Nowadays, many environmental mechanics equipment manufacturers have joined forces. While giving full play to their own advantages, they are also closely linked to each other and designed composite test equipment. For a high and low temperature hydraulic vibration test system, it is necessary to ensure that the high and low temperatures generated by the high and low temperature chamber will not have a great impact on the hydraulic vibration table body, and at the same time, the vibration level of the hydraulic vibration table body will not cause vibration impact on the high and low temperature chamber body.

[0003] At present, the influence of high and low temperatures on the hydraulic vibration table body mainly comes from the high and low temperatures transferring cold and heat to the workbench surface, and the workbench surface transfers cold and heat to the piston rod of the hydraulic exciter through the connector. The piston rod contains oil seal seals, which will be affected by cold and heat and cause material failure, reducing the service life of the hydraulic exciter. To address the above problems, the current method adopted by manufacturers is mainly to lay FR-4 heat insulation boards on the workbench surface. This method can only temporarily reduce heat conduction and cannot solve the heat conduction problem for a long time. If a material with very good heat insulation effect is used, it is not suitable due to high cost.

[0004] In view of this, it is necessary to improve the existing equipment to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an adapter with a temperature control function to solve the problem that the existing workbench surface transfers cold and heat to the piston rod of the hydraulic exciter through the connector, thereby reducing the service life of the hydraulic exciter.

The adapter with a temperature control function is provided with a through hole for the piston to insert, a cooling groove is arranged around the through hole in the adapter with a temperature control function, and a water inlet and a water outlet communicating with the cooling groove are arranged on the adapter with a temperature control function.

[0007] As a further improvement of the present invention, the adapter with a temperature control function includes a columnar first body and a columnar second body. The diameter of the first body is larger than that of the second body. The cooling groove includes a first cooling groove arranged in the first body and a second cooling groove arranged in the second body. The first cooling groove is communicated with the second cooling groove, and the water inlet and the water outlet are respectively communicated with the first cooling groove and the second cooling groove.

The first process hole is connected to the communication hole, and the first process hole and the communication hole are respectively communicated with the first cooling groove and the second cooling groove.

[0009] As a further improvement of the present invention, the adapter with a temperature control function further includes a second process hole extending radially. The second process hole is used to communicate the water inlet and the first cooling groove.

[0010] As a further improvement of the present invention, both the first process hole and the second process hole are opened radially inward from the side wall of the first body, and a plug is provided on the side close to the side wall of the first body to close the first process hole and the second process hole.

[0011] As a further improvement of the present invention, the adapter with a temperature control function further includes a first pressing plate provided on the side of the first body close to the second body to cover the first cooling groove, and a second pressing plate provided on the side of the second body away from the first body to cover the second cooling groove.

[0030] As Figures 1 to 10 shown, the comprehensive environmental test device 100 of the present invention includes an environmental test chamber 1, a workbench 2 disposed inside the environmental test chamber 1, a connector 3 connected to the workbench 2, a vibrator 4 having a piston 41, an adapter 5 with a temperature control function, and a test bench 6 for supporting the workbench 2 and the vibrator 4. The adapter 5 with a temperature control function is used to connect the piston 41 and the connector 3.

[0031] The vibrator 4 is used to generate vibrations, which are transmitted axially through the piston 41 to the adapter 5 and the connector 3, and further transmitted to the workbench 2 to drive the specimen on the workbench 2 to vibrate.

[0032] The environmental test chamber 1 surrounds the workbench 2 to create the required working environment for the specimen on the workbench 2, especially to control the temperature.

[0033] The adapter 5 with a temperature control function is used to connect to the piston 41 and cool the piston 41.

[0034] The adapter 5 with a temperature control function is provided with a through hole 51 for the piston 41 to insert. The piston 41 is inserted into the through hole 51 and fixed to the adapter 5 with a temperature control function.

[0035] The adapter 5 with temperature control function includes a columnar first body 52, a columnar second body 53, a cooling groove 54 arranged around the through hole 51, a first process hole 55 extending radially, a communication hole 56 extending axially, a second process hole 57 extending radially, a water inlet 58 and a water outlet 59 communicating with the cooling groove 54, a water pipe joint 50 communicating with the water inlet 58 and the water outlet 59 and a water pipe 501 connected to the water pipe joint 50, a first pressing plate 502, and a second pressing plate 503.

[0036] The diameter of the first body 52 is larger than that of the second body 53. The second body 53 faces the vibrator 4. The piston 41 is inserted from the second body 53. A fixing member 522 is arranged radially in the through hole 51 on the first body 52. The piston 41 and the fixing member 522 are fixedly connected by screws. The first body 52, the second body 53, and the through hole 51 are coaxially arranged.

[0037] A through hole 521 is provided on the first body 52. The first body 52 is fixedly connected to the connector 3 by passing a bolt or a screw through the through hole 521.

[0038] The first body 52 and the second body 53 are integrally formed.

[0039] The cooling groove 54 includes a first cooling groove 541 arranged in the first body 52 and a second cooling groove 542 arranged in the second body 53. The first cooling groove 541 and the second cooling groove 542 are as close as possible to the through hole 51. The piston 41 fills the through hole 51 to abut against the first body 52 and the second body 53, thereby improving the cooling effect.

[0040] The first cooling groove 541 and the second cooling groove 542 are arranged at intervals along the axial direction of the piston 41, increasing the area of heat transfer to further improve the cooling effect.

[0041] The first cooling groove 541 communicates with the second cooling groove 542. The water inlet 58 and the water outlet 59 communicate with the first cooling groove 541 and the second cooling groove 542 respectively. Thus, only one water inlet 58 and one water outlet 59 are needed to provide constant temperature cooling liquid for the first cooling groove 541 and the second cooling groove 542. Of course, in other modes, two water inlets 58 and two outlets can also be arranged to communicate with the first cooling groove 541 and the second cooling groove 542 respectively. Correspondingly, the first process hole 55, the second process hole 57, and the communication hole 56 can be omitted. The constant temperature cooling liquid in this embodiment is constant temperature water.

[0042] The first process hole 55 is connected to the communication hole 56, and the first process hole 55 and the communication hole 56 are respectively communicated with the first cooling groove 541 and the second cooling groove 542.

[0043] The second process hole 57 is used to communicate the water inlet 58 and the first cooling groove 541.

[0044] Both the first process hole 55 and the second process hole 57 are radially inwardly opened from the side wall of the first body 52, and a plug 581 is provided on one side close to the side wall of the first body 52 to close the first process hole 55 and the second process hole 57. Further, a gasket 582 is provided in the first process hole 55 and the second process hole 57 to improve the sealing effect.

[0045] In this embodiment, neither the first cooling groove 541 nor the second cooling groove 542 is a complete circle, and the two ends are not communicated along the circumferential direction.

[0046] The coolant flow path is as follows: The constant-temperature coolant is injected through the water inlet 58, enters one end of the first cooling groove 541 through the second process hole 57, the coolant flows along the first cooling groove 541 to the other end, enters one end of the second cooling groove 542 after passing through the first process hole 55 and the communication hole 56, the coolant flows along the second cooling groove 542 to the other end, and then is discharged from the water outlet 59.

[0047] The first pressing plate 502 is disposed on the side of the first body 52 close to the second body 53 to cover the first cooling groove 541, and the second pressing plate 503 is disposed on the side of the second body 53 away from the first body 52 to cover the second cooling groove 542.

[0048] Both the first pressing plate 502 and the second pressing plate 503 are disposed on the side facing the vibrator 4.

[0049] On the side of the first pressing plate 502 facing the first body 52, two first sealing grooves 5021 are recessed inwardly. Two first sealing members 5022 are provided in the two first sealing grooves 5021. The two first sealing grooves 5021 are radially disposed inside and outside the first cooling groove 541. The first sealing member 5022 is used to prevent the liquid in the first cooling groove 541 from leaking.

[0050] On the side of the second pressing plate 503 facing the second body 53, two second sealing grooves 5031 are recessed inwardly. Two second sealing members 5032 are provided in the two second sealing grooves 5031. The two second sealing grooves 5031 are radially disposed inside and outside the second cooling groove 542. The second sealing member 5032 is used to prevent the liquid in the second cooling groove 542 from leaking.

[0051] The comprehensive environment testing device 100 of the present invention and the adapter 5 with a temperature control function can control the temperature of the piston 41 by setting the adapter 5 with a temperature control function, thereby reducing the influence of high and low temperatures on the piston 41; by setting the first cooling groove 541 and the second cooling groove 542 spaced axially, the heat conduction area with the piston 41 can be increased; the adapter 5 with a temperature control function has strong rigidity and does not affect the vibration level transmission, has a low manufacturing cost, and can be disassembled or the supply of the constant temperature coolant can be cut off when not needed.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
