Description

Technical Field

[0001] The utility model relates to the technical field of automobile component detection, in particular to an engine piston air leakage detection device. Background Art

[0002] The air tightness of the engine piston is a technical issue that is closely concerned in engine manufacturing. Whether it is the performance inspection after the engine is produced or the repair and maintenance of the automobile engine after sale, the leakage of the engine piston needs to be tested to ensure the performance of the engine.

[0003] In the related technology, the air tightness of the automobile engine cylinder directly determines the efficiency of the engine, so the air tightness inspection is particularly important. When conducting air tightness inspection on the traditional engine cylinder, not only the operation steps are cumbersome, which greatly reduces the inspection efficiency, but also after the inspection, the various air pipes cannot be rolled up, so that the air pipes are easily placed randomly during storage, resulting in damage to the air pipes, which affects the piston leakage detection and causes technical problems such as inaccurate piston leakage detection data.

[0004] Therefore, a device for detecting the gas leakage of an engine piston is proposed. Utility Model Content

[0005] The utility model aims to provide an engine piston leakage detection device, which solves the problems raised in the above background technology by setting an air pipe reeling assembly to reel in a hose so that the hose can be properly stored when not in use.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An engine piston leakage detection device comprises a support frame and a pressure-stabilizing tank. Two pressure-stabilizing tanks are provided, and the two pressure-stabilizing tanks are symmetrically fixedly mounted on the top of the support frame and connected through a pipeline. A flow meter is also commonly connected between the two pressure-stabilizing tanks. A connecting pipe is provided at the bottom of one of the pressure-stabilizing tanks, and the connecting pipe is connected to a hose. A winding assembly is fixedly mounted in the middle of the support frame.

[0008] Preferably, the winding assembly includes a fixed frame, a winding wheel, and a fixed block. The fixed frame is fixedly installed in the middle of the support frame, the winding wheel is rotatably installed on the fixed frame, the fixed block is fixedly installed on the surface of the winding wheel, and the fixed block is provided with a clamping mechanism for clamping the hose.

[0009] Preferably, a sliding rod is slidably mounted on the winding wheel, a positioning hole is opened on the fixing frame, a handle is fixedly connected to one end of the sliding rod, and a spring is provided between the handle and the side wall of the winding wheel.

[0010] Preferably, the clamping mechanism includes a spring 2 and an arc block. Two springs 2 are provided and the two springs 2 are symmetrically arranged on the inner wall of the fixed block. Two arc blocks are provided and the two arc blocks are respectively fixedly connected to the spring 2.

[0011] Preferably, a positioning cylinder is fixedly mounted on one of the fixing plates, and a latch is sleeved on the positioning cylinder.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Set up a reel assembly to reel up the hose. When the hose is not used for testing, reel the hose onto the reel assembly and leave it still, to avoid the hose being randomly placed when not in use, causing damage to the hose due to random sliding. In addition, universal wheels are provided to facilitate the movement of the testing device.

[0014] 2. A spring and an arc block are arranged on the reel to form a clamping mechanism to clamp and fix one end of the hose, so that when the hose is reeled in, it is only necessary to rotate the reel, and there is no need to manually wind the hose before reeling it in, which makes the operation more convenient.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides an engine piston leakage detection device, and the technical solution is as follows:

[0021] An engine piston leakage detection device comprises a support frame 1 and a pressure stabilizing tank 4, wherein two pressure stabilizing tanks 4 are provided, and the two pressure stabilizing tanks 4 are symmetrically fixedly mounted on the top of the support frame 1 and are connected through a pipeline, and a flow meter 5 is also commonly connected between the two pressure stabilizing tanks 4, wherein a connecting pipe 15 is provided at the bottom of one of the pressure stabilizing tanks 4, and the connecting pipe 15 is connected to a hose, a winding assembly is fixedly mounted in the middle of the support frame 1, and a universal wheel 2 is fixedly mounted on the bottom wall of the support frame 1.

[0022] When testing, manually push the device to the engine to be tested, start the engine, connect one end of the hose to the engine's respirator port, and observe the flow meter 5 connected to the display screen of the site's central control system through a data cable. The data can be observed on the central control display screen, and it is convenient to record multiple times. After the leakage of the piston is obtained, the hose is rolled up using the winding assembly to prevent the hose from being damaged by being placed anywhere. Figure 2 As shown, the winding assembly includes a fixed frame 7, a winding wheel 3, and a fixed block 6. The fixed frame 7 is fixedly installed in the middle of the support frame 1, the winding wheel 3 is rotatably installed on the fixed frame 7, and the fixed block 6 is fixedly installed on the surface of the winding wheel 3. The fixed block 6 is provided with a clamping mechanism for clamping the hose.

[0023] When winding the hose, one end of the hose is manually held by a clamping mechanism, and then the winding wheel 3 is rotated to wind the hose. A sliding rod 9 is slidably mounted on the winding wheel 3, and a positioning hole 11 is provided on the fixing frame 7. A handle 10 is fixedly connected to one end of the sliding rod 9, and a spring 8 is provided between the handle 10 and the side wall of the winding wheel 3.

[0024] When rotating the winding wheel 3, a person holds the handle 10 and pulls it outward, so that the sliding rod 9 is disengaged from the positioning hole 11, thereby ensuring sustainable rotation. When the winding wheel 3 completes collecting the hose, a certain length is reserved. The person manually rotates the sliding rod 9 to a position aligned with the positioning hole 11 and then releases the handle 10. The sliding rod 9 is inserted into the positioning hole 11 under the action of the spring, and the winding wheel 3 is fixed to prevent the winding wheel 3 from automatically rotating during movement.

[0025] like Figure 3 As shown, the clamping mechanism includes a spring 12 and an arc block 13. There are two springs 12, which are symmetrically arranged on the inner wall of the fixed block 6. There are two arc blocks 13, which are respectively fixedly connected to the spring 12. An opening 14 is opened on the fixed block 6.

[0026] When clamping, the person manually pushes the hose into the opening 14 with force, and the hose generates a thrust on the two arc blocks 13, and the compression spring 2 12 is compressed to both sides until the hose is moved between the two arc blocks 13. Under the elastic force of the spring 2 12, the arc block 13 applies pressure to the hose and clamps the hose, thereby completing the fixation of the hose. When the hose needs to be taken out, the arc block 13 is pressed to compress the spring 2 12, or the hose can be directly pulled out with force.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
