Description

Technical Field

[0001] The utility model relates to a semi-automatic water testing machine for an engine cylinder, belonging to the technical field of engine detection. Background Art

[0002] The engine block is the core component of the automobile engine, and its sealing quality directly affects the performance, safety and stability of the engine. In order to ensure the quality of the engine block and to ensure that there are no problems such as air leakage and water seepage during use, each engine block must undergo a strict sealing test after production.

[0003] At present, the industry generally uses the airtightness test method to test the sealing of the engine cylinder. The basic process of this method is: first, the cylinder is sealed by a specific tool; then, the staff needs to move the cylinder into the water; then, the cylinder is inflated and its sealing performance is evaluated by observing the generation of bubbles.

[0004] However, this method has some obvious shortcomings in practical applications:

[0005] 1. The cylinder body is heavy, and manual handling not only increases the labor intensity of workers, but also easily causes damage to the cylinder body during handling. This not only affects the appearance quality of the product, but may also have a potential impact on the sealing performance of the cylinder body, and may even cause greater safety hazards.

[0006] 2. After the cylinder is put into the water, its position is not fixed, which makes it very difficult to find the leak point when there is a leak. This not only increases the difficulty of detection, but also prolongs the detection time and affects production efficiency.

[0007] 3. After the inspection, the cylinder body needs to be manually moved to the draining table again to drain the water before the cylinder body can be assembled. During this process, the residual water on the cylinder body is easy to drip onto the ground, resulting in a slippery working environment, which not only affects work efficiency, but may also cause problems such as workers slipping, posing a high safety hazard. Utility Model Content

[0008] In order to solve the problems existing in the background technology, the utility model provides a semi-automatic water testing machine for an engine cylinder.

[0009] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a semi-automatic water testing machine for an engine cylinder, comprising a test water tank, a lifting system and a fixed platform; the lifting system comprises a cylinder, a lifting slide block, a lifting chain, a lifting sprocket, a lifting bracket and a frame; a vertically arranged frame is fixed in the test water tank, the frame is fixedly connected to the cylinder body of the vertically arranged cylinder, the movable end of the cylinder is fixedly connected to the lifting slide block, the lifting slide block is fixedly connected to one end of the lifting chain, the other end of the lifting chain is fixedly connected to the lifting bracket, and the lifting chain is meshedly connected to the lifting sprocket, the lifting sprocket is rotatably arranged at the upper end of the frame, and a fixed platform is placed on the lifting bracket.

[0010] The lifting sliding block is slidably connected to the frame.

[0011] The lifting bracket is slidably connected to the frame.

[0012] The fixed platform includes a detection table, a bottom inflatable sealing ring, a positioning block group, a fixing mechanism and a sealing mechanism; the detection table is placed on a lifting bracket, and a bottom inflatable sealing ring, a positioning block group, a fixing mechanism and a sealing mechanism are fixed to the upper end of the detection table, and the bottom inflatable sealing ring is connected to an air source.

[0013] The fixing mechanism includes a rear clamping cylinder and a front clamping cylinder; the cylinder body of the rear clamping cylinder is fixed at the rear end of the detection platform, and the cylinder body of the front clamping cylinder is fixed at the front end of the detection platform, and the movable end of the rear clamping cylinder and the movable end of the front clamping cylinder are both arranged in cooperation with the cylinder body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model realizes rapid and accurate sealing of the cylinder body through a fixed platform, avoids the cumbersome operation of sealing with specific tooling, saves working time and improves working efficiency.

[0017] 2. The utility model replaces the traditional manual handling of the cylinder body by hoisting the fixed platform, which reduces the intensity of personnel work, reduces the number of operators, and reduces labor costs.

[0018] 3. During the operation of the utility model, the cylinder body is always fixed on a fixed platform, which avoids the problem of bumping during the sealing test. At the same time, the position is fixed, which is convenient for quickly finding the leak point, shortening the detection time and avoiding the risk of problematic products flowing out.

[0019] 4. After the work is completed, the utility model can directly drain the cylinder body, avoiding the situation where the workpiece is carried with water during transportation, preventing environmental pollution caused by a large amount of water accumulated on the ground, and effectively avoiding potential safety hazards caused by water sliding.
