Description

Technical Field

[0001] This utility model relates to the field of engine breather testing technology, specifically a low-cost engine breather air tightness testing device. Background Technology

[0002] Engine breather functions to balance pressure during operation. It allows the crankcase cavity to communicate with the atmosphere, relieving excessive pressure and preventing oil leakage from seals, gaskets, and other components. It also reduces oil consumption and prevents oil deterioration. During engine breather production, airtightness testing is necessary to ensure the normal operation of the engine lubrication system. This testing requires an airtightness testing device, such as the engine breather airtightness testing bench (application number 202122357410.X). This bench uses a clamping block to fix the test workpiece, and then injects air directly into the workpiece using a testing cylinder and an air gun. This method is fast, cost-effective, and provides good testing results for products with low sealing pressure. Furthermore, the replaceable air gun allows for compatibility with different product seals, broadening the device's applicability.

[0003] During the testing process, impurities and scale will be generated after prolonged use of the liquid. The testing station mentioned in the above application does not have the function of preventing scale buildup. After prolonged use, scale will corrode the device, thereby shortening its service life and increasing testing costs. Therefore, we propose a low-cost engine breather airtightness testing device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-cost engine breather air tightness testing device to solve the problem mentioned in the background art that it does not have the function of preventing scale buildup during use, and that scale buildup corrodes the device after long-term use, thereby shortening the device's service life and increasing testing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-cost engine breather air tightness testing device, including a water tank, the left side surface of the water tank is convex, and an air pump is bolted to the upper surface of the convex position of the water tank, and the output end of the air pump is connected to an air gun through an external hose.

[0006] The water tank has a sliding placement plate inside, and a limit plate is slidably provided on the lower surface of the placement plate. A fixing block is fixedly connected to the inner wall of the water tank, and the fixing blocks are symmetrically distributed on both sides of the water tank.

[0007] The water tank is rotatably equipped with a connecting shaft inside, and a rotating shaft is also rotatably equipped inside the water tank. A moving block is fixedly connected to both the surface of the rotating shaft and the surface of the connecting shaft.

[0008] A working plate is fixedly connected to the right side surface of the water tank, and a camera is fixedly connected to the lower surface of the working plate.

[0009] Preferably, a column is fixedly connected to the inner wall of the water tank, and a baffle is fixedly connected to the end of the column. The placement plate is slidably disposed on the surface of the column, and the columns are symmetrically distributed on both sides of the placement plate.

[0010] Preferably, a first spring that provides elastic reset is fixedly connected to the lower surface of the placement plate, and the other side of the first spring is fixedly connected to the inner wall of the water tank.

[0011] Preferably, both sides of the placement plate are hollow structures, and an inner rod is fixedly connected to the inner wall of the placement plate. A slider is slidably disposed on the surface of the inner rod, and the limiting plate is fixedly connected to the lower surface of the slider. The end of the slider is located outside the water tank.

[0012] Preferably, the limiting plate corresponds one-to-one with the fixing block, and the surface of the limiting plate is inclined. The surface of the placement plate is fixedly connected to a second spring, and the other side of the second spring is fixedly connected to the surface of the slider.

[0013] Preferably, a traction rope is fixedly connected to the lower surface of the placement plate, and the other side of the traction rope is wound and fixedly connected to the surface of the connecting shaft, and a main gear is fixedly connected to the surface of the connecting shaft.

[0014] Preferably, a secondary gear that meshes with the main gear is fixedly connected to the surface of the rotating shaft, and the actuating blocks are evenly distributed on both the surface of the connecting shaft and the surface of the rotating shaft, and the surface of the actuating blocks is inclined.

[0015] Preferably, a torsion spring is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the water tank. A partition is fixedly connected to the surface of the connecting shaft, and the partition is located on both sides of the traction rope.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this low-cost engine breather airtightness testing device adopts a novel structural design, the specific details of which are as follows:

[0017] This low-cost engine breather air tightness testing device works by inflating the workpiece and then placing it on a placement plate. The placement plate is then pressed by a slider, causing the limiting plate to move to the underside of the fixing block. Under the action of the limiting plate, the fixing block, and the second spring, the placement plate remains stably in the water tank. The camera detects the air bubbles inside the tank. The workflow is quick and convenient, and the operating cost is low.

[0018] Furthermore, when it is necessary to remove the workpiece, the slider is moved inwards on the placement plate. The slider causes the limiting plate to move synchronously. When the limiting plate is no longer in contact with the fixed block, the placement plate rises back to its original position under the action of the second spring and the column. At this time, the worker can directly remove the workpiece.

[0019] Furthermore, the slider is always located outside the water surface, so workers do not need to come into contact with the liquid when picking up and placing workpieces, thus ensuring the cleanliness of the liquid, avoiding the number of liquid changes, and reducing costs.

[0020] This low-cost engine breather air tightness testing device initially has a torsion spring in a stretched state. When the placement plate descends, the connecting shaft loses the tension of the traction rope. At this time, the connecting shaft rotates under the action of the torsion spring. When the connecting shaft rotates, it shakes the liquid by a moving block, preventing scale from settling in the liquid.

[0021] Furthermore, when the connecting shaft rotates, it drives the rotating shaft to rotate through the main gear and the auxiliary gear. When the rotating shaft rotates, it also shakes the liquid by moving the agitator, which helps to optimize the prevention of scale formation.

[0022] Furthermore, the actuating blocks are evenly distributed on the surfaces of the connecting shaft and the rotating shaft, which increases the amplitude of liquid sloshing, improves work efficiency, and reduces costs.

[0023] (3) When the placement plate rises again, the placement plate drives the connecting shaft to rotate through the traction rope. At this time, the torsion spring will be stretched, which facilitates the next use of the torsion spring. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This invention provides the following technical solution: a low-cost engine breather air tightness testing device:

[0033] Example 1: Using the designated placement plate 8, the inflated workpiece can be quickly submerged in the liquid, such as... Figures 1-2 As shown, the system includes a water tank 1. The left side surface of the water tank 1 is raised, and an air pump 2 is bolted to the upper surface of the raised part of the water tank 1. The output end of the air pump 2 is connected to an air gun 3 through an external hose. A placement plate 8 is slidably arranged inside the water tank 1, and a limit plate 12 is slidably arranged on the lower surface of the placement plate 8. A fixing block 13 is fixedly connected to the inner wall of the water tank 1, and the fixing blocks 13 are symmetrically distributed on both sides of the water tank 1. A working plate 6 is fixedly connected to the right side surface of the water tank 1, and a camera 7 is fixedly connected to the lower surface of the working plate 6. A column 4 is fixedly connected to the inner wall of the water tank 1, and a baffle 5 is fixedly connected to the end of the column 4. A placement plate 8 is slidably arranged on the surface of the column 4, and the column 4 is symmetrically distributed on both sides of the placement plate 8.

[0034] Both sides of the placement plate 8 are hollow structures, and an inner rod 10 is fixedly connected to the inner wall of the placement plate 8. A slider 11 is slidably arranged on the surface of the inner rod 10, and a limiting plate 12 is fixedly connected to the lower surface of the slider 11. The limiting plate 12 corresponds one-to-one with the fixing block 13, and the surface of the limiting plate 12 is inclined. A second spring 14 is fixedly connected to the surface of the placement plate 8, and the other side of the second spring 14 is fixedly connected to the surface of the slider 11.

[0035] During operation, the air pump 2 is turned on, and the air pump 2 supplies air to the air gun 3 through the external hose. Finally, the air gun 3 inflates the engine breather. After that, the workpiece is placed on the placement plate 8. At this time, the operator can press the slider 11 to lower the placement plate 8. After the limiting plate 12 contacts the fixing block 13, the limiting plate 12 will be pushed, which will drive the slider 11 to move in the direction of squeezing the second spring 14. After the limiting plate 12 moves below the fixing block 13, the limiting plate 12 and the slider 11 return to their original positions under the action of the second spring 14. At this time, the fixing block 13 presses against the limiting plate 12, and the first spring 9 is in a squeezed state. At this time, the situation inside the water tank 1 is observed through the camera 7 to complete the inspection.

[0036] Example 2: Unlike Example 1, the placement plate 8 can be quickly returned to its original position, such as... Figures 2-4 As shown, the end of the slider 11 is located on the outside of the water tank 1. The lower surface of the placement plate 8 is fixedly connected to a first spring 9 that plays an elastic reset role. The other side of the first spring 9 is fixedly connected to the inner wall of the water tank 1. The water tank 1 is rotatably provided with a connecting shaft 15 and a rotating shaft 17. The surfaces of the rotating shaft 17 and the connecting shaft 15 are both fixedly connected with a toggle block 19.

[0037] After the inspection is completed, when the placement plate 8 needs to be returned to its original position, the slider 11 is moved. At this time, the slider 11 drives the limiting plate 12 to move in a direction that does not contact the fixing block 13. When the limiting plate 12 does not contact the fixing block 13, the placement plate 8 rises under the action of the first spring 9 and the column 4. Finally, the staff can take away the workpiece. During the placement and removal of the workpiece, the staff does not need to come into contact with the liquid, which ensures the cleanliness of the liquid and reduces the need for frequent liquid replacement, thus reducing costs.

[0038] Example 3: Unlike Example 2, the connecting shaft 15, rotating shaft 17, and actuating block 19 allow the liquid to slosh without causing clumping. Figure 5 and Figure 6As shown, a traction rope 20 is fixedly connected to the lower surface of the placement plate 8, and the other side of the traction rope 20 is wound and fixedly connected to the surface of the connecting shaft 15. A main gear 16 is fixedly connected to the surface of the connecting shaft 15, and a secondary gear 18 that meshes with the main gear 16 is fixedly connected to the surface of the rotating shaft 17. The actuating blocks 19 are evenly distributed on the surface of the connecting shaft 15 and the surface of the rotating shaft 17, and the surface of the actuating blocks 19 is inclined. A torsion spring 21 is fixedly connected to the surface of the connecting shaft 15, and the other side of the torsion spring 21 is fixedly connected to the inner wall of the water tank 1. A partition 22 is fixedly connected to the surface of the connecting shaft 15, and the partition 22 is located on both sides of the traction rope 20.

[0039] Initially, the torsion spring 21 is in a stretched state. When the placement plate 8 descends, the connecting shaft 15 loses the tension of the traction rope 20. At this time, the connecting shaft 15 rotates under the action of the torsion spring 21. When the connecting shaft 15 rotates, it drives the rotating shaft 17 to rotate through the main gear 16 and the secondary gear 18. As a result, the agitator 19 on the surface of the connecting shaft 15 and the agitator 19 on the surface of the rotating shaft 17 can agitate the liquid, preventing scale from settling and preventing scale from forming. This extends the service life of the water tank 1 and reduces costs.

[0040] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
