Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a cylinder liner falling off detection device for automated die casting production. Background Technology

[0002] In the automated die-casting production process, some products require steel cylinder liners to be placed into the mold before die-casting. During this process, because the cylinder liners are relatively shallow, they may fall out during the die-casting mold closing process, which is somewhat random. However, customers need wear resistance in this position. If the cylinder liner is not in the product and is not detected in time, it will lead to a reduction in the service life of the vehicle. Therefore, it is necessary to improve this process. Utility Model Content

[0003] This utility model provides a cylinder liner detachment detection device for automated die-casting production that can accurately and effectively detect the presence of cylinder liners in products without affecting normal processes, thus ensuring product quality. It solves the technical problem that in the prior art, some products have a certain possibility of cylinder liners falling off during the die-casting mold closing process, which is easily missed by manual observation and cannot be accurately detected by ordinary detection methods, thus affecting the safety of product operation.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: a cylinder liner falling off detection device for automated die casting production, including a cooling island for intermediate process, the cylinder liner is conveyed by a conveyor belt, the cylinder liner is heated by high frequency and then enters the die casting machine to be die-cast integrally with the product, the formed product is held by a robot arm and cooled on the cooling island, the product is then cut after cooling, the cooling island is provided with a number of positioning columns for positioning the product, and the center of the cooling island is provided with a detection device for detecting whether there is a cylinder liner in the product, and the detection is performed while the product is being air-cooled. In the automated production process, the cylinder liner is placed on a conveyor belt and held by a robotic arm to a heating island for high-frequency heating. After heating, the cylinder liner is then fed into the mold of the die-casting machine by the robotic arm. Molten aluminum is injected into the mold to form the cylinder liner. The formed product is then held by the robotic arm and placed on a cooling island for cooling. After cooling, the product is held by the robotic arm and then moved to the cutting section for machining. On the cooling island, an air-cooled fan cools the product. During the cooling process, a detection device uses magnetic detection to determine whether there is a cylinder liner inside the product. If a cylinder liner is detected, the product is conveyed to the next process normally. If no cylinder liner is detected, the product is scrapped and cannot proceed to the next process. The entire automated production is controlled by a system.

[0005] Preferably, the positioning post has an "I"-shaped structure, with the die-cast stalk on the product placed on the end face of the positioning post. The position and height of the positioning post are set and adjusted according to the actual dimensions of the product.

[0006] Preferably, the detection device includes several positioning sleeves fixed to the surface of the cooling island, with the product cavity secured to the outside of each positioning sleeve. Each positioning sleeve contains a magnetic detection sensor. On the cooling island, an air-cooled fan cools the product. During the cooling process, two magnetic detection sensors inside the positioning sleeves detect the product. Since the product is made of non-magnetic aluminum and the cylinder liner is made of steel, the magnetic detection sensors detect the presence of a cylinder liner inside. If a cylinder liner is detected, the product is normally conveyed to the next process; if no cylinder liner is detected, the product is scrapped and cannot proceed to the next process. The entire automated production is controlled by the system.

[0007] Preferably, the magnetic detection sensors have different heights. The number of magnetic sensors is set according to the number of cylinder liners in the product, and the height of the magnetic sensors is adjusted according to the cylinder liner size.

[0008] Preferably, the detection head of the magnetic detection sensor is higher than the positioning sleeve. The positioning sleeve mainly serves for positioning and protection, while the detection head of the magnetic detection sensor is higher than the positioning sleeve to ensure accurate detection.

[0009] Preferably, the positioning sleeve is a C-shaped arc sleeve. The arc-shaped positioning sleeve in this invention serves two purposes: it protects the internal magnetic detection sensor and it allows for positioning and alignment with the product.

[0010] Preferably, the positioning sleeve is made of a non-magnetic material with good heat resistance. To avoid affecting the judgment of the magnetic detection sensor, the positioning sleeve in this invention is made of a non-magnetic metal material with good heat resistance.

[0011] Preferably, a fan is provided on one side of the cooling island. The fan is installed on one side of the cooling island to cool the product.

[0012] Therefore, the cylinder liner falling off detection device of this utility model for automated die casting production has the following advantages: it can detect the product without affecting the normal process, and can accurately and effectively detect whether there is a cylinder liner in the product, thus ensuring product quality.

[0016] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example:

[0018] like Figure 1 and 2 As shown, a cylinder liner fall-off detection device for automated die-casting production includes a cooling island 1 for intermediate processes. The cylinder liner is conveyed on a conveyor belt, and a robot clamps the cylinder liner on the conveyor belt onto a heating island for high-frequency heating. After heating, the cylinder liner is fed into a die-casting machine by the robot and die-cast together with the product. After the product is formed, it is clamped onto the cooling island 1 by the robot for air cooling. Some parts of the cooling island 1 are equipped with air-cooling fans. After the product is cooled, it is clamped onto the cutting part for cutting.

[0019] Two positioning posts 2 for positioning products are fixedly installed on the cooling island 1. The positioning posts 2 have an "I" shaped structure, and the die-cast material handle on the product is placed on the end face of the positioning posts 2.

[0020] A detection device for detecting whether there is a cylinder liner inside the product is fixedly installed on the cooling island 1 between the positioning columns 2, and the detection is performed while the product is being cooled by air.

[0021] The testing device includes two positioning sleeves 3 fixedly installed on the cooling island 1, with the product cavity fastened to the outside of the positioning sleeves 3; the positioning sleeves 3 are "C"-shaped arc sleeves, and the positioning sleeves 3 are made of non-magnetic material with good heat resistance.

[0022] Each positioning sleeve 3 is equipped with a magnetic detection sensor 4. The two magnetic sensors 4 are at different heights, and the detection head of the magnetic detection sensor 4 is higher than that of the positioning sleeve 3.

[0023] In the automated production process, the cylinder liner is placed on the conveyor belt and held by a robot to the heating island for high-frequency heating. After heating, the cylinder liner is then sent into the mold of the die-casting machine by the robot. Molten aluminum is injected into the mold to form the cylinder liner. After forming, the product is held by the robot and placed on the cooling island 1 for cooling. After cooling, the product is held by the robot and then held by the robot to the cutting part for cutting.

[0024] On cooling island 1, air-cooled fans cool the product. During the cooling process, two magnetic detection sensors 4 inside positioning sleeve 3 detect the product. Since the product is made of aluminum and is non-magnetic, and the cylinder liner is made of steel, the magnetic detection sensors 4 will detect whether there is a cylinder liner inside. If a cylinder liner is detected, the product is normally conveyed to the next process. If no cylinder liner is detected, the product is scrapped and cannot enter the next process. The entire automated production is controlled by the system.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
