Description

Technical Field

[0001] The present disclosure relates to the technical field of oil wear particle sensors, and in particular, to an accuracy testing device for oil wear particle sensors. Background Art

[0002] The oil wear particle sensor's monitoring accuracy (recognition rate) test for metal particles is currently generally performed manually, where metal particles of different sizes are pasted onto transmission parts (such as nylon ties, plastic hoses), passed through the oil wear particle sensor's sensing channel, and then the oil wear particle sensor's metal particle recognition results are checked to determine the oil wear particle sensor's monitoring accuracy (recognition rate) for metal particles.

[0003] Usually, in order to test the monitoring accuracy of metal particles of different types (ferromagnetic or non-ferromagnetic) and different sizes, it is necessary to manually test a single metal particle many times. After the test is completed, other metal particles are replaced and the steps are repeated for testing. This testing method greatly increases the manual workload, the operation steps are cumbersome, and the test efficiency is low. The speed of metal particles passing through the sensing channel of the oil wear sensor is also manually controlled. Different personnel have different operating methods, and it is difficult to standardize the speed and avoid human testing errors. In addition, manual testing is prone to problems such as misdetection and missed detection, and has the defect of low automation. Utility Model Content

[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise specified, “inside and outside” refer to the inside and outside of the corresponding component outline; in addition, it should be noted that the terms used, such as “first, second”, etc., are used to distinguish one element from another.

[0027] According to the first aspect of the present disclosure, Figure 1 As shown, a precision testing device 1 for an oil wear particle sensor 2 is provided. The device may include a transmission member 11 and a driving mechanism 12. The transmission member 11 is used to connect the metal particles 3 to be tested. The driving mechanism 12 includes a driving wheel 121, at least one guide wheel 122 and at least one tensioning structure 123. The transmission member 11 surrounds the driving wheel 121, the guide wheel 122 and the tensioning structure 123. The driving mechanism 12 is used to drive the transmission member 11 to move so as to drive the metal particles 3 to be tested to pass through the sensing channel 21 of the oil wear particle sensor 2. The transmission member 11 includes a transmission section 111 located between any two of at least one guide wheel 122, at least one tensioning structure 123 and the driving wheel 121. At least one transmission section 111 is used to pass through the sensing channel 21 of at least one oil wear particle sensor 2.

[0028] Through the above technical solution, during assembly, the transmission member 11 can be wrapped around the driving wheel 121, the guide wheel 122 and the tensioning structure 123. When the accuracy of the oil wear particle sensor 2 needs to be tested, the metal particles 3 to be tested can be connected to the transmission member 11, and the transmission member 11 can be moved under the drive of the driving mechanism 12 to drive the metal particles 3 to be tested to pass through the sensing channel 21 of the oil wear particle sensor 2, thereby achieving the purpose of testing the accuracy of the oil wear particle sensor 2. The accuracy testing device 1 provided by the present disclosure avoids the problems of low test efficiency and low test accuracy caused by the manual testing method in the related art, and also saves labor costs. Further, the transmission member 11 includes a transmission section 111 located between any two of at least one guide wheel 122, at least one tensioning structure 123 and the driving wheel 121. At least one transmission section 111 is used to pass through the sensing channel 21 of at least one oil wear particle sensor 2. Such a configuration can achieve the purpose of using a single accuracy testing device 1 to test the accuracy of multiple oil wear particle sensors 2 at the same time, further improving the efficiency of the accuracy test of the oil wear particle sensors 2 .

[0029] It should be noted that the connection method between the metal particles 3 to be tested and the transmission element 11 can be bonding, clamping, etc., which is not limited here, and those skilled in the art can make design adjustments according to actual conditions.

[0030] In some embodiments, Figure 1 As shown, the driving mechanism 12 may further include a driving member 124. The driving member 124 is connected to the driving wheel 121 to drive the driving wheel 121 to rotate. The transmission member 11 can move with the rotation of the driving wheel 121. For example, the driving member 124 can be selected as a stepper motor. In this embodiment, a stepper motor is used as the driving member 124 mainly to utilize its advantages such as simple structure and good control performance. Of course, it can be understood that the driving member 124 can also be used in other ways, which is not limited here, and those skilled in the art can choose according to actual conditions. The setting of the driving member 124 enables the driving wheel 121 to uniformly drive the transmission member 11 to move at a set speed, so as to avoid the problem in the related art that the speed of the metal particles 3 to be tested passing through the sensing channel 21 cannot be unified due to manual testing, resulting in a relatively low test accuracy. The setting of the driving member 124 improves the test accuracy of the precision testing device 1.

[0031] In some embodiments, Figure 1 As shown, the precision testing device may further include a fixed platform 13. The driving mechanism 12 is disposed on the fixed platform 13. The fixed platform 13 is used to place or connect the oil wear particle sensor 2. As a carrier of the entire precision testing device 1, the fixed platform 13 can realize the centralized arrangement of various components in the precision testing device 1, and has the performance of anti-vibration, anti-impact, etc., so as to ensure that the precision testing device 1 works stably and reliably.

[0032] In some embodiments, Figure 1 and Figure 2 As shown, the tensioning structure 123 may include an adjustment seat 123b disposed on the fixed platform 13 and a tensioning wheel 123a adjustable in position to the adjustment seat 123b. The tensioning wheel 123a is used to abut the transmission member 11 to tension the transmission member 11. The setting of the tensioning structure 123 can realize the control of the tightness of the transmission member 11, so that the transmission member 11 can always maintain a suitable tension state to drive the metal particles 3 to be tested to pass through the sensing channel 21 smoothly.

[0033] In a specific embodiment, Figure 2As shown, the adjustment seat 123b may include an elastic member 123c, a seat body 123d having a slide groove, and a mounting shaft 123e slidably connected to the slide groove. The tensioning wheel 123a is sleeved on the mounting shaft 123e. The elastic member 123c is connected between the mounting shaft 123e and the seat body 123d. When tensioning, the transmission member 11 can drive the tensioning wheel 123a to pull the spring to extend, so that the transmission member 11 always maintains a tensioned state. Further, as Figure 2 As shown, the adjustment seat 123b may also include an adjustment member 123f and a locking member 123g. One end of the adjustment member 123f passes through the seat body 123d and is connected to the end of the elastic member 123c that faces away from the installation shaft 123e, and the other end of the adjustment member 123f is connected to the locking member 123g. The adjustment member 123f is used to adjust the initial position of the installation shaft 123e in the slide groove through the elastic member 123c. For example, the adjustment member 123f may be a bolt, and the locking member 123g may be a nut. One end of the bolt passes through the seat body 123d and is connected to the elastic member 123c, and the other end is locked by a nut. The method of using bolts and nuts to achieve adjustment is simple and reliable. Furthermore, the elastic member 123c may be a spring.

[0034] In some embodiments, Figure 1 As shown, the precision testing device 1 also includes a first support seat 14, a second support seat 15 and a third support seat 16. The driving member 124 is connected to the fixed platform 13 through the first support seat 14. The guide wheel 122 is connected to the fixed platform 13 through the second support seat 15. The adjustment seat 123b is connected to the fixed platform 13 through the third support seat 16. The first support seat 14, the second support seat 15 and the third support seat 16 are configured so that the driving wheel 121, the guide wheel 122 and the tensioning wheel 123a are located at the same height relative to the fixed platform 13. The arrangement of the first support seat 14, the second support seat 15 and the third support seat 16 can make the transmission member 11 surrounding the driving wheel 121, the guide wheel 122 and the driving wheel parallel to the fixed platform 13, and thus can smoothly and reliably pass through the sensing channel 21. The arrangement of the first support seat 14, the second support seat 15 and the third support seat 16 improves the test reliability of the precision testing device 1.

[0035] In some embodiments, Figure 1As shown, the precision testing device 1 also includes a plurality of connecting members 17, and the first support seat 14, the second support seat 15 and the third support seat 16 are respectively connected to the fixed platform 13 through the connecting members 17. Among them, a connecting portion 131 is provided on the fixed platform 13, and the first support seat 14, the second support seat 15 and the third support seat 16 can be respectively connected to the corresponding connecting portion 131 through the connecting member 17. For example, the connecting portion 131 on the fixed platform 13 can be configured as a plurality of threaded holes, and correspondingly, the connecting member 17 can be configured as a bolt. It can be understood that the connection method of the connecting portion 131 and the connecting member 17 can also be a buckle, a slide groove or the like, which is not limited here, and those skilled in the art can adjust it according to the actual situation.

[0036] In some embodiments, the first support seat 14 is an insulating member. For example, the first support seat 14 can be constructed as a bakelite support block. The bakelite support block has good insulation. While providing support for the driver 124, it isolates the contact between the driver 124 and the fixed platform 13, avoiding electromagnetic noise from being transmitted to the fixed platform 13 when the driver 124 is started and operated, and then transmitted to the oil sensor, avoiding electromagnetic interference to the oil sensor. Of course, the first support seat 14 can also be made of other insulating materials, which is not limited here, and those skilled in the art can make adjustments according to actual conditions.

[0037] In some embodiments, the transmission member 11 can be configured as a synchronous belt. One side of the synchronous belt has a tooth portion 112 meshed with the driving wheel 121, and the other side is used to connect the metal particles 3 to be tested. Such a design can ensure that the driving wheel 121 and the transmission member 11 are effectively meshed, and the driving wheel 121 can reliably drive the transmission member 11 to move.

[0038] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0040] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
