Description

Technical Field

[0001] This application relates to the technical field of flow controller testing devices, and more specifically, to a flow controller testing device. Background Technology

[0002] Flow controllers are commonly used in precision machine tools. By adjusting the area of ​​the throttling channel orifice and the length of the throttling channel, the flow controller changes the magnitude of the local resistance, thereby controlling the flow rate and thus changing the oil film stiffness of the precision machine tool.

[0003] When performing various performance tests on a flow controller, a flow controller testing device is required to secure it. Common flow controller testing devices typically use a structure with a lead screw, a clamping block, and a fixing block, with the clamping block connected to the lead screw. By adjusting the lead screw, the flow controller is fixed between the clamping block and the fixing block. Subsequently, an oil outlet connector is installed on the flow controller's oil outlet, and a high-pressure oil outlet pipe is installed on the oil outlet connector to test the oil outlet. However, during testing, this device requires constant assembly and disassembly of the flow controller's oil outlet, which reduces the testing efficiency to some extent. Summary of the Invention

[0004] The main objective of this application is to provide a flow controller testing device to at least solve the problem in the prior art where the flow controller testing device requires constant assembly and disassembly of the nut at the oil outlet of the flow controller during testing, resulting in low testing efficiency when testing a large number of flow controllers.

[0008] The clamping component is mounted on the base and there is an installation space between the clamping component and the positioning test seat. The clamping component is used to press the flow controller installed in the installation space against the positioning test seat.

[0009] Furthermore, the clamping component includes:

[0010] A clamping mechanism is mounted on the base.

[0011] The fastening mechanism has an installation space and is mounted on the base to secure the flow controller within the installation space. The fastening mechanism is slidably disposed between the clamping mechanism and the positioning test seat.

[0012] The clamping mechanism is used to press the flow controller, which is fixed by the fastening mechanism, against the positioning test seat.

[0013] Furthermore, the fastening mechanism includes:

[0014] The base plate is positioned between the clamping mechanism and the positioning test seat, and slides back and forth between the clamping mechanism and the positioning test seat;

[0015] The fixing block is set on the base plate;

[0016] The first abutting component is mounted on the base plate and spaced apart from the fixing block to form an installation space. The line connecting the first abutting component and the fixing block is perpendicular to the sliding direction of the base plate. The first abutting component is used to apply force to the flow controller in the installation space to fix the flow controller between the fixing block and the first abutting component.

[0017] Furthermore, the first abutting component includes a first abutting block and a first driving part. The first driving part is connected to the first abutting block, and the first abutting block moves in a direction close to or away from the fixed block under the drive of the first driving part.

[0018] Furthermore, the flow controller testing device also includes:

[0019] A guide shaft is connected to a fixed block and extends along the direction from the fixed block to the first abutting block. The flow controller includes a flow control block with a through hole adapted to the guide shaft. The flow control block is detachably mounted on the guide shaft through the through hole.

[0020] Furthermore, the guide shaft comes in various models, each with a different length, and these various models can be selectively mounted on the fixed block;

[0021] Flow controllers come in various models, each with a different number of flow control blocks. These different models of flow controllers are matched one-to-one with different models of guide shafts. During testing, the flow controller is installed on the guide shaft of the corresponding model.

[0022] Furthermore, the institutions that provide support include:

[0023] The second drive unit is mounted on the base.

[0024] The second abutting block is connected to the second driving unit, and the second abutting block moves between the clamping mechanism and the positioning test seat under the drive of the second driving unit.

[0025] Furthermore, the flow controller testing device also includes an elastic element, which is disposed between the positioning test seat and the fastening mechanism.

[0026] Furthermore, the sliding direction of the fastening mechanism is the first direction, and the flow controller testing device also includes:

[0027] An adjusting block is set on the base. The adjusting block and the positioning test seat are located on the same side of the fastening mechanism. The adjusting block and the positioning test seat are spaced apart along a second direction perpendicular to the first direction.

[0032] Furthermore, the flow controller testing device also includes a sealing element disposed at the end of the channel for connection with the oil outlet.

[0033] Compared to the structure of existing flow controller testing devices, the clamping component in this application connects the oil outlet of the flow controller to the channel on the positioning test base. This means that when testing the parameters of each oil outlet of the flow controller, the operator only needs to operate the channel corresponding to the oil outlet to obtain the test results, without needing to install nuts and external pipes on the oil outlet before testing. Similarly, after the test, the flow controller testing device of this application only needs to remove the fixed flow controller. It eliminates the need to disassemble the nuts and pipes installed at the oil outlet after removing the flow controller. Furthermore, for testing different models of flow controllers, the operator only needs to replace the flow controller with the appropriate model. Therefore, the structure provided in this application improves testing efficiency to a certain extent when testing flow controllers in batches. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0045] See Figures 1 to 5 As shown, according to an embodiment of this application, a flow controller testing device is provided. To address the problem that the flow controller testing device requires continuous assembly and disassembly of the nut at the oil outlet of the flow controller 50 during testing, resulting in low testing efficiency when testing a large number of flow controllers, this embodiment improves the flow controller testing device.

[0046] Specifically, the flow controller testing device includes a base 10, a positioning test seat 20, and a clamping assembly. The positioning test seat 20 is mounted on the base 10 and has a channel 22. One end of the channel 22 is connected to a connector 21, and the other end is used to connect to the oil outlet (not shown in the figure) of the flow controller 50. The clamping assembly is mounted on the base 10, and there is an installation space between the clamping assembly and the positioning test seat 20. The clamping assembly is used to press the flow controller 50, installed in the installation space, against the positioning test seat 20.

[0047] In this embodiment, the flow controller 50 is installed within the mounting space of the clamping assembly. After the clamping assembly secures the flow controller 50, the oil outlet on the flow controller 50 can communicate with the channel 22 on the positioning test base 20. One end of the channel 22 is connected to a connector 21, and an external oil pipe is connected to the connector. When testing the flow controller 50, the oil from the oil outlet enters the channel 22, and then flows through the connector 21 into the external oil pipe for testing.

[0048] Compared to the structure of existing flow controller testing devices, in this embodiment, the clamping component connects the oil outlet of the flow controller 50 to the channel 22 on the positioning test base 20. This means that when testing the parameters of each oil outlet of the flow controller 50, the operator only needs to operate the channel 22 corresponding to the oil outlet to obtain the test results, without needing to install nuts and external pipes on the oil outlet before testing. Similarly, after the test, the flow controller testing device of this embodiment only needs to remove the fixed flow controller 50. It eliminates the need to disassemble the nuts and pipes installed at the oil outlet after removing the flow controller 50. Furthermore, for testing different models of flow controllers 50, the operator only needs to replace the flow controller 50 with the appropriate model. Therefore, when testing flow controllers in batches, the structure provided in this embodiment improves testing efficiency to a certain extent.

[0049] Furthermore, the clamping assembly in this embodiment includes a clamping mechanism 30 and a fastening mechanism 40. The clamping mechanism 30 is disposed on the base 10. The fastening mechanism 40 has an installation space and is mounted on the base 10 to fix the flow controller 50 within the installation space. The fastening mechanism 40 is slidably disposed between the clamping mechanism 30 and the positioning test seat 20.

[0050] Specifically, in this embodiment, the mounting space in the fastening mechanism 40 is used to install the flow controller 50. The fastening mechanism 40 can provide external force in a direction perpendicular to the clamping mechanism 30 to the positioning test seat 20 to fix the flow controller 50. Simultaneously, the fastening mechanism 40 is also provided with a slide rail 411, which allows the fastening mechanism 40 to slide between the clamping mechanism 30 and the positioning test seat 20. The clamping mechanism 30 presses the flow controller 50, fixed by the fastening mechanism, against the positioning test seat 20. This arrangement, on the one hand, provides external force in a direction perpendicular to the clamping mechanism 30 to the positioning test seat 20, making the flow controller 50 more effectively fixed. On the other hand, the external force provided by the clamping mechanism 30 connects the oil outlet on the flow controller 50 to the channel 22 on the positioning test seat 20, allowing personnel to test the flow controller 50 through the channel 22.

[0051] Further, the fastening mechanism 40 in this embodiment includes a base plate 41, a fixing block 42, and a first abutting component 43. The base plate 41 is disposed between the clamping mechanism 30 and the positioning test seat 20, and slides reciprocally between them. The fixing block 42 is disposed on the base plate 41. The first abutting component 43 is mounted on the base plate 41 and spaced apart from the fixing block 42 to form an installation space. The line connecting the first abutting component 43 and the fixing block 42 is perpendicular to the sliding direction of the base plate 41. The first abutting component 43 applies force to the flow controller 50 within the installation space to fix the flow controller 50 between the fixing block 42 and the first abutting component 43.

[0052] Specifically, in this embodiment, a slide rail 411 is provided under the base plate 41. The slide rail 411 is fixed on the base 10, and the slide rail 411 allows the base plate 41 to slide back and forth between the clamping mechanism 30 and the positioning test seat 20. The first abutting component 43 can fix the flow controller 50 in the installation space in a direction perpendicular to the clamping mechanism 30 to the positioning test seat 20.

[0053] The first abutting component 43 includes a first abutting block 431 and a first driving part 432. The first driving part 432 is connected to the first abutting block 431. The first abutting block 431 moves in a direction close to or away from the fixed block 42 under the drive of the first driving part 432.

[0054] Specifically, in this embodiment, the first driving unit 432 is a hydraulic cylinder. Before testing, oil is supplied to the hydraulic cylinder, which pushes the first abutment block 431 connected to it towards the fixing block 42, ultimately locking the flow controller 50, which is installed in the installation space, against the fixing block 42. After the test, oil is supplied to the hydraulic cylinder in the reverse direction, causing the first abutment block 431 to move in the opposite direction, after which the flow controller 50 is removed. In this embodiment, the hydraulic cylinder is easy to operate and also effectively improves the fixing effect of the flow controller 50.

[0055] Optionally, the first drive unit 432 may be a cylinder, or a motor lead screw assembly or other drive components. Any other modifications under the concept of this application are within the protection scope of this application.

[0056] Furthermore, in this embodiment, the clamping mechanism 30 includes a second driving part 31 and a second abutting block 32. The second driving part 31 is mounted on the base 10. The second abutting block 32 is connected to the second driving part 31 and moves between the clamping mechanism 30 and the positioning test seat 20 under the drive of the second driving part 31.

[0057] Specifically, in this embodiment, the second drive unit 31 is configured as a quick clamp. Before testing, the operator first uses the fastening mechanism 40 to fix the flow controller 50, and then pulls the quick clamp upwards, causing the second abutment block 32 to push the flow controller 50 against the positioning test seat 20. At this time, the oil outlet of the flow controller 50 is connected to the channel 22 of the positioning test seat 20, and then the flow controller 50 can be tested. After the test, the operator pulls the quick clamp downwards, the second abutment block 32 returns to its original position, and then reverses the oil supply to the cylinder, so that the flow controller 50 can be removed.

[0058] Furthermore, in this embodiment, multiple channels 22 and multiple connectors 21 are provided, with each channel 22 corresponding to a different connector 21. The multiple channels 22 are arranged sequentially along a direction perpendicular to the clamping mechanism 30 to the positioning test seat 20, and the other end of each channel 22 corresponds sequentially to a multiple oil outlet on the flow controller 50.

[0059] Furthermore, in this embodiment, the flow controller testing device also includes a guide shaft 421. The guide shaft 421 is connected to the fixing block 42 and extends along the direction from the fixing block 42 to the first abutment block 431. The flow controller 50 includes a flow control block 51, and the flow control block 51 is provided with a through hole 52 adapted to the guide shaft 421. The flow control block 51 is detachably mounted on the guide shaft 421 through the through hole 52.

[0060] Specifically, in this embodiment, the guide shaft 421 can limit the flow controller 50 to a corresponding position, so that after the flow controller 50 is pressed by the pressing component, the oil outlet on the flow controller 50 can be precisely aligned with the channel 22 on the positioning test seat 20. (See attached...) Figures 1 to 5 As shown, in this embodiment, there are four through holes 52, which are respectively located at the four corners of the flow control block 51. When the flow controller 50 is fixed by the clamping assembly, the first abutting block 431 will not interfere with the guide shaft 421.

[0061] Furthermore, in this embodiment, the guide shaft 421 has multiple models, and the guide shaft 421 of different models has different lengths. Different models of guide shaft 421 can be selectively mounted on the fixing block 42. The flow controller 50 has multiple models, and the multiple models of flow controller 50 have different numbers of flow control blocks 51. The multiple models of flow controller 50 are set one-to-one with the multiple models of guide shaft 421. During testing, the flow controller 50 is mounted on the corresponding model of guide shaft 421.

[0062] Specifically, to accommodate different models of flow controllers 50, guide shafts 421 of varying lengths are selected in this embodiment. This indicates that when the number of flow control blocks 51 in the flow controller 50 is large or small, the operator can select a matching guide shaft 421, ensuring that the multiple oil outlets to be tested on the flow controller 50 can be connected one-to-one with the multiple channels 22 on the positioning test base 20. Simultaneously, the guide shaft 421 has threads, allowing it to connect with the pre-drilled mounting holes on the fixing block 42. This connection method facilitates quick replacement of the guide shaft 421 by the operator.

[0063] Furthermore, the flow controller testing device in this embodiment also includes an elastic element 80. The elastic element 80 is disposed between the positioning test seat 20 and the fastening mechanism 40. Specifically, in this embodiment, the elastic element 80 can be a helical spring or a rubber spring; in this embodiment, a helical spring is selected. During testing, the helical spring is compressed under pressure. After the test is completed and the quick clamp is pulled down, the helical spring rebounds, causing the fastening mechanism 40 to quickly return to its pre-test position.

[0064] Furthermore, in this embodiment, the sliding direction of the fastening mechanism 40 is a first direction, and the flow controller testing device also includes an adjusting block 70. The adjusting block 70 is disposed on the base 10, and the adjusting block 70 and the positioning test seat 20 are located on the same side of the fastening mechanism 40. The adjusting block 70 and the positioning test seat 20 are spaced apart along a second direction perpendicular to the first direction. Secondly, there are multiple elastic elements 80, a portion of which are disposed between the positioning test seat 20 and the fastening mechanism 40, and another portion of which are disposed between the adjusting block 70 and the fastening mechanism 40.

[0065] Specifically, in this embodiment, multiple springs are provided between the positioning test seat 20 and the fastening mechanism 40, as well as between the adjusting block 70 and the fastening mechanism 40. The structure in this embodiment allows the fastening mechanism 40 to return to its original position more smoothly. Simultaneously, the adjustment block 70 ensures the balance of the spring force, preventing uneven force distribution on the fastening mechanism 40 during rebound.

[0066] Furthermore, in this embodiment, connector 21 includes a male quick connector 211 and a female quick connector 212. The male quick connector 211 is connected to channel 22, and the female quick connector 212 is connected to the male quick connector 211. A control switch is provided on the male quick connector 211.

[0067] Specifically, in this embodiment, the male quick connector 211 and the female quick connector 212 are connected in a plug-in relationship. The male quick connector 211 has a control switch, and the female quick connector 212 is used to connect to an external oil pipe. When testing each oil outlet of the flow controller 50, the operator only needs to install the female quick connector 212 onto the male quick connector 211 of the corresponding channel 22 of the oil outlet to be tested. At this time, the control switch of the male quick connector 211 is opened, and the oil flows into the external oil pipe through the connector 21, thus completing the test. The structure of this embodiment is convenient to operate and improves testing efficiency to a certain extent. Meanwhile, the control switch of the male quick connector 211 without the female quick connector 212 is in the closed state, and the oil cannot flow out. This means that, by adopting the structure of this embodiment, oil is prevented from flowing out of the untested connector 21 during testing, thus preventing contamination of the workbench.

[0068] Furthermore, the flow controller testing device in this embodiment also includes a limiting block 60. The limiting block 60 is disposed on the base 10 and located on the side of the fastening mechanism 40 near the clamping mechanism 30. The limiting block 60 provides resistance when the fastening mechanism 40 rebounds, preventing the fastening mechanism 40 from rebounding excessively. At the same time, the setting of the limiting block 60 allows the fastening mechanism 40 to quickly return to its pre-test position.

[0069] Furthermore, in this embodiment, the flow controller testing device also includes a sealing element 23. The sealing element 23 is disposed at the end of the channel 22 for connection with the oil outlet. In this embodiment, the sealing element 23 is a sealing ring. After the oil outlet of the flow controller 50 is connected to the positioning test seat 20, the sealing ring can effectively prevent oil leakage.

[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
