Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and particularly to a liquid level test bench. Background Art

[0002] In the fields of industrial production and transportation, the oil pot is an important oil storage device, and its liquid level test plays a key role in the safe and stable operation of equipment. By simulating the tilting postures (such as uphill, downhill, and turning) when the vehicle is running or parked, the accuracy of the liquid level indicator is tested and verified, and it is ensured that there is sufficient lubricating oil in the oil pot to cover the key components at extreme angles, avoiding serious damage to the engine caused by dry friction.

[0003] The existing oil pot liquid level test bench includes a test base, a rotating seat arranged on the test base, and a clamping seat rotatably installed on the rotating seat. A rotating motor or a rotating handle for driving the clamping seat to rotate is installed on the rotating seat, and a clamping tooling for fixing the oil pot is arranged on the clamping seat. The tester fixedly installs the oil pot on the clamping tooling and drives the clamping seat to rotate, so that the oil pot tilts, and judges whether the design of the oil pot is qualified by observing the tilting state of the liquid level.

[0004] In view of the above related technologies, the test bench can only perform one-way tilting tests on the oil pot. If it is necessary to detect the liquid level conditions of the oil pot in different tilting directions, it is necessary to remove and readjust the installation position of the clamping tooling. This process not only consumes a lot of time and energy, but also easily causes measurement errors due to improper operation. Summary of the Invention

Since the disclosed embodiments of the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the gravity direction. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] The following will Figures 1-5 further elaborate on the present application in detail.

[0035] An embodiment of the present application discloses a liquid level test bench.

[0036] Refer to Figure 1, the liquid level test bench includes an adjusting base 1, a support platform 2 installed on the adjusting base 1, and a liquid level tooling 3 provided on the top of the support platform 2 for installing the product 4. The adjusting base 1 successively includes a first adjusting component 11 and a second adjusting component 12 from bottom to top. The adjusting directions of the first adjusting component 11 and the second adjusting component 12 are perpendicular. Define the adjusting direction of the first adjusting component 11 as left - right adjustment, and the adjusting direction of the second adjusting component 12 as front - back adjustment.

[0037] The second adjusting component 12 is arranged on the top of the first adjusting component 11, and the support platform 2 is arranged on the second adjusting component 12. By adjusting the support platform 2 left - right through the first adjusting component 11, the product 4 on the liquid level tooling 3 is driven to tilt left - right. By adjusting the first adjusting component 11 front - back through the second adjusting component 12, the product 4 on the liquid level tooling 3 is driven to tilt front - back. Through the adjustment of the two groups of adjusting components, the liquid level change state of the product 4 in different tilting states is simulated.

[0038] Refer to Figure 1 and Figure 2 , the support platform 2 includes a support bottom plate 21 fixed to the top of the second adjusting component 12, a support vertical plate 22 vertically fixed to the support bottom plate 21, and a support top plate 23 fixed to the top of the support vertical plate 22. The support bottom plate 21 and the second adjusting component 12 are fixed by bolts. There are support positioning grooves 211 on the top of the support bottom plate 21 and the bottom of the support top plate 23 for positioning and placing the support vertical plate 22. Both ends of the support vertical plate 22 are fixedly connected to the support top plate 23 and the support bottom plate 21 by bolts. Among them, reinforcing plates 24 are also arranged at both ends of the support vertical plate 22, and the cross - section of the reinforcing plates 24 is triangular. One right - angled side of the reinforcing plate 24 is bolt - fixed to the support vertical plate 22, and the other right - angled side is bolt - fixed to the support bottom plate 21 or the support top, which is used to improve the overall structural strength of the support platform 2.

[0039] The liquid level tooling 3 is fixed to the support top plate 23 by bolts, and a product placement groove 31 for positioning and placing the product 4 is provided on the liquid level tooling 3. The liquid level tooling 3 is disassembled and installed on the support top. Therefore, according to different products 4, the liquid level tooling 3 for this product 4 is designed. In this embodiment, the product 4 takes an oil kettle as an example.

[0040] Refer to Figure 1 and Figure 3, the first adjustment component 11 includes a first adjustment base 111 and a first adjustment slider 112 slidably mounted on the first adjustment base 111. The first adjustment base 111 is in the shape of a rectangular block, and support and strengthening columns 13 are installed at the four corners of its bottom, and a fixed bottom plate 14 is provided at the bottom of the support and strengthening columns 13. The support and strengthening columns 13 and the first adjustment base 111 are bolted together, and the fixed bottom plate 14 is fixed to the working ground (not marked in the figure). Through the arrangement of the support and strengthening columns 13 and the fixed bottom plate 14, the overall structural strength of the liquid level test bench is made more reliable, and the probability of tipping due to the center of gravity shifting is reduced.

[0041] The top of the first adjustment base 111 has a first adjustment chute 1111 for the first adjustment slider 112 to slide. The first adjustment chute 1111 is an overall concave arc-shaped chute, and the first adjustment base 111 is also provided with an adjustment dovetail block at the top of the first adjustment chute 1111. The bottom of the first adjustment slider 112 has a dovetail chute that cooperates with the adjustment dovetail block.

[0042] The overall structure of the second adjustment component 12 is the same as that of the first adjustment component 11. It includes a second adjustment base 121 and a second adjustment slider 122 slidably mounted on the second adjustment base 121. The second adjustment base 121 and the first adjustment slider 112 are bolted together. The top of the second adjustment base 121 has a second adjustment chute for the second adjustment slider 122 to slide. The difference between the second adjustment component 12 and the first adjustment component 11 is that the extending direction of the second adjustment chute is perpendicular to that of the first adjustment chute 1111.

[0043] Sliding drive members 15 are provided on the outer side walls in the length direction of the first adjustment slider 112 and the second adjustment slider 122. By means of the sliding drive members 15, the first adjustment slider 112 and the second adjustment slider 122 are rotated, so that the adjustment angle is more labor-saving and convenient. The sliding drive member 15 is an overall circular cylinder, which is fixed in the middle of the first adjustment slider 112. Angle scale lines 16 corresponding to the sliding drive member 15 are provided on the side walls of the first adjustment base 111 and the second adjustment base 121. The angle scale lines 16 take the lowest point of the first adjustment chute 1111 as the zero scale line and gradually increase towards both sides.

[0044] Refer to Figure 3 and Figure 4 , in order to ensure that the first adjustment slider 112 and the second adjustment slider 122 remain fixed after sliding to a specific angle, the present application further includes a locking component 5. The locking component 5 includes an extension rod body 51, a rotating cam 52 and a first limit tooth surface 53.

[0045] The extension rod body 51 and the sliding driving member 15 are coaxially fixed. The extension rod body 51 is inserted into the corresponding adjusting slider, and the rotating cam 52 is fixedly installed at the end of the extension rod body 51. In this embodiment, the locking assembly 5 in the first adjusting slider 112 is taken as an example. There is an arrangement groove 1121 corresponding to the rotating cam 52 in the first adjusting slider 112. The first adjusting base 111 is provided with a rotating arc groove 1112 corresponding to the arrangement groove 1121 on the side wall of the first adjusting chute 1111. The extending direction of the rotating arc groove 1112 is the same as the moving direction of the first adjusting slider 112.

[0046] The first limiting tooth surface 53 is located on the side of the rotating cam 52 away from the extension rod body 51, and the tooth surfaces of the first limiting tooth surface 53 are arranged at equal intervals in the horizontal direction. The inner wall of the rotating arc groove 1112 is provided with a second limiting tooth surface 1113 that meshes with the first limiting tooth surface 53. When the first limiting tooth surface 53 and the second limiting tooth surface 1113 are in mating contact, it can lock the rotation of the first adjusting slider 112. Among them, the distance between adjacent tooth grooves of the first limiting tooth surface 53 is the same as the distance between the scale lines. In this embodiment, the radian of the adjacent tooth grooves centered on the rotation center of the adjusting slider is 0.5°, so as to improve the angle accuracy during measurement.

[0047] In order to reduce the probability that the first limiting tooth surface 53 and the second limiting tooth surface 1113 interfere and get stuck during the rotation of the rotating cam 52. A limiting block 54 is slidably mounted on the rotating cam 52, and the first limiting tooth surface 53 is arranged on the limiting block 54. A driving assembly 6 for driving the limiting block 54 to slide back and forth in the rotating cam 52 is arranged in the extension rod body 51.

[0048] Combined Figure 5 , the driving assembly 6 includes a first driving rod 61, a second driving rod 62 and a driving gear 63. The first driving rod 61 is an L-shaped rod body as a whole, including a first rod body 611 arranged horizontally and a second rod body 612 arranged vertically. The second rod body 612 is fixedly connected to the limiting block 54, and the fixing method can be fixed by bolts or welding.

[0049] There is a driving installation groove 151 for installing the driving assembly 6 in the sliding driving member 15 and the extension rod body 51. One end of the driving installation groove 151 penetrates the outer side wall of the sliding driving member 15. The first rod body 611 is limitedly arranged in the driving installation groove 151, and the top of the first rod body 611 has a first rack 613 along the length direction. The second driving rod 62 is limitedly arranged in the driving installation groove 151 and is located above the first rod body 611. The bottom of the second driving rod 62 has a second rack 621 along the length direction.

[0050] The driving gear 63 is rotatably installed between the second driving rod 62 and the first rod body 611, and both the first rack 613 and the second rack 621 are meshed and cooperated with the driving gear 63. When the operator pulls the second driving rod 62 from the opening end of the driving installation groove 151, the first rod body 611 is driven to slide into the driving installation groove 151 through the driving gear 63, so that the first limiting tooth surface 53 can abut and mesh with the second limiting tooth surface 1113.

[0051] A connecting collar 622 is installed at the end of the second driving rod 62, and a connecting fastener 152 that is cooperated and clamped with the connecting collar 622 is installed on the outer end surface of the sliding driving member 15. After the second driving rod 62 is pulled out of the sliding driving member 15, the locking of the second driving member is realized through the cooperation of the connecting collar 622 and the connecting fastener 152, that is, the locking of the limiting block 54 is realized, ensuring the meshing stability of the first limiting tooth surface 53 and the second limiting tooth surface 1113.

[0052] Wherein, the end of the second driving rod 62 also has a limiting end 623, and the outer diameter of the limiting end 623 is greater than the overall outer diameter of the second driving rod 62. There is a limiting sinking groove 153 for arranging the limiting end 623 in the sliding driving member 15, and a limiting elastic member 154 is installed in the limiting sinking groove 153 of the sliding driving member 15. The limiting elastic member 154 is a tension spring member, and its two ends are respectively fixed to the bottom wall of the limiting sinking groove 153 and the limiting end 623. In the normal state of the limiting elastic member 154, the first limiting tooth surface 53 and the second limiting tooth surface 1113 are in a separated state.

[0053] A fixing block 55 is arranged on the outer side wall of the extending rod body 51, and a plunger member 551 is installed in the fixing block 55. The plunger member 551 includes a plunger housing, a plunger spring and a plunger ball head. The plunger housing is inserted into the fixing block 55 by interference fit, and the plunger spring is arranged along the axis of the fixing block 55. The two ends of the plunger spring are respectively fixed to the plunger ball head and the inner bottom wall of the plunger housing. There is a fixing arc groove 1122 corresponding to the fixing block 55 in the first adjusting slider 112. The radian of the fixing arc groove 1122 is 180°, and the plunger locking holes 1123 for the plunger ball head to be inserted are arranged on the inner walls at both ends of the fixing arc groove 1122 of the first adjusting slider 112. When the plunger ball head is cooperated with one group of plunger locking holes 1123, the whole rotating cam 52 is located in the arranging groove 1121. When the plunger ball head is cooperated with the other group of plunger locking holes 1123, the rotating cam 52 and the second limiting tooth surface 1113 correspond.

[0054] The implementation principle of a liquid level test bench according to an embodiment of the present application is as follows: during measurement, the operator pulls the sliding drive member 15 to drive the first adjustment slider 112 or the second adjustment slider 122 to slide. After moving to the required angle, the operator rotates the sliding drive member 15 so that the rotating cam 52 moves to the rotating arc groove 1112, and then pulls the second drive rod 62 outwards so that the connecting collar 622 and the connecting fastener 152 are engaged and clamped, realizing the locking of the first adjustment slider 112 and the second adjustment slider 122. After that, the operator adjusts the other set of adjustment components to obtain the liquid level change state of the product 4 at this inclination angle.

[0055] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
