Description

Technical Field

[0001] This invention relates to the field of casting processing equipment technology, and in particular to a grinding device for casting processing. Background Technology

[0002] After casting is completed, the surface of the casting usually has uneven parts such as gating and riser residue, burrs, and flash, which need to be polished. At present, common casting polishing equipment mostly uses belt sanders, angle grinders or special polishing workstations. These devices mainly use high-speed rotating sand belts, grinding wheels or grinding heads to grind the surface of the casting.

[0003] However, existing grinding equipment has significant drawbacks: the grinding process generates a large amount of metal dust and abrasive dust, which easily disperses into the working environment. This not only severely pollutes the workshop air and affects the health of workers, but also reduces visibility, making it difficult for operators to clearly observe the grinding progress and surface quality of the castings. This can lead to under-grinding or over-grinding, affecting product yield. Furthermore, the diffused dust poses an explosion hazard and requires frequent workshop cleaning, increasing maintenance costs.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop a grinding device for casting processing, aiming to overcome the shortcomings of existing casting grinding devices, such as serious dust pollution, harsh working environment, and impact on processing quality. Summary of the Invention

[0005] In order to overcome the shortcomings of existing casting grinding devices, such as serious dust pollution, harsh working environment, and impact on processing quality, this application provides a grinding device for casting processing.

[0006] The grinding device for casting processing provided in this application adopts the following technical solution: A grinding device for casting processing includes an angle grinder for processing castings and a protective box for placing the angle grinder. The protective box is characterized by having a conveying mechanism for transferring unprocessed castings into the protective box, a conveying mechanism for transporting processed castings out of the protective box, and a protective mechanism for preventing dust from escaping the protective box. The top surface and one side along the length of the protective box are both made of transparent protective glass. The other side along the length of the protective box has a mounting hole, in which a transparent protective plate is hinged. A protective glove is mounted on the transparent protective plate and can be inserted into the protective box.

[0007] By adopting the above technical solution, the angle grinder is placed inside a protective box. The top surface and one side along the length of the protective box are made of transparent protective glass. The other side along the length of the protective box has a mounting hole, and a transparent protective plate is hinged inside the mounting hole. Protective gloves are installed on the transparent protective plate, which can be inserted into the protective box. During the grinding process, the worker wearing protective gloves puts their hands into the protective box. The conveying mechanism transports the unprocessed casting into the protective box, and the worker picks up the angle grinder to grind the casting. The protective mechanism prevents dust from escaping from the protective box. After the casting is ground, the conveying mechanism transports the processed casting out of the protective box, reducing dust pollution and creating a good working environment for the workers.

[0008] Preferably, the protective box has a feeding hole on one side in the width direction. The conveying mechanism includes a first conveying pipe connected to the feeding hole, a first conveyor belt disposed in the first conveying pipe, a second conveying pipe connected to the first conveying pipe, a second conveyor belt disposed in the second conveying pipe, a first infrared sensor for detecting whether the casting on the second conveyor belt is close to the first conveyor belt, and a lever for moving the casting on the second conveyor belt onto the first conveyor belt. The first conveyor belt passes through the feeding hole and is inserted into the protective box. The conveying direction of the second conveyor belt is perpendicular to the conveying direction of the first conveyor belt. The second conveyor belt, the first infrared sensor, and the lever are disposed in the first conveying pipe.

[0009] By adopting the above technical solution, a feeding hole is opened on one side of the protective box in the width direction. The first conveying pipe is connected to the feeding hole. The first conveyor belt is set in the first conveying pipe and passes through the feeding hole and is inserted into the protective box. The second conveying pipe is connected to the first conveying pipe. The second conveyor belt is set in the second conveying pipe. The conveying direction of the second conveyor belt is perpendicular to the conveying direction of the first conveyor belt. The second conveyor belt, the first infrared sensor, and the lever are set in the first conveying pipe. During the process of conveying the unprocessed casting, the casting is placed on the second conveyor belt for conveying. When the first infrared sensor detects the casting, it drives the lever to move the casting from the second conveyor belt to the first conveyor belt and then conveys it into the protective box by the first conveyor belt, which facilitates the conveying of the unprocessed casting.

[0010] Preferably, a sliding groove is formed on the inner side wall of the first conveying pipe, and a limiting groove is formed on the bottom wall of the sliding groove. The conveying mechanism includes a motor I disposed in the limiting groove, a screw fixed to the output shaft of the motor I, a slider threaded onto the screw, a rotating seat disposed on the slider, a motor II disposed on the rotating seat, and a rotating shaft fixed to the output shaft of the motor II. The screw is rotatably disposed in the limiting groove, the slider is slidably disposed in the limiting groove, the rotating seat is slidably disposed in the sliding groove, and the lever is fixed to the rotating shaft and rotatably disposed in the sliding groove.

[0011] By adopting the above technical solution, a sliding groove is formed on the inner wall of the first conveying pipe, and a limiting groove is formed on the bottom wall of the sliding groove. Motor 1 is installed in the limiting groove, a screw is fixed to the output shaft of Motor 1, and the screw is rotatably installed in the limiting groove.

Motor 2 is installed on the rotating seat, a rotating shaft is fixed to the output shaft of Motor 2, and a lever is fixed to the rotating shaft and rotatably installed in the sliding groove. When it is necessary to move the casting from the second conveyor belt to the first... When the casting is on the first conveyor belt, the second drive motor drives the rotating shaft to rotate in the forward direction, causing the lever to turn towards the side of the casting. The first drive motor drives the screw to rotate in the forward direction. Under the limiting action of the limiting groove, the slider drives the rotating seat to move closer to the first conveyor belt. Under the connection of the rotating seat, rotating shaft and lever, the lever drives the casting to slide towards the first conveyor belt, which facilitates the casting to be moved from the second conveyor belt to the first conveyor belt. Then the second drive motor drives the rotating shaft to rotate in the reverse direction, causing the lever to move away from the side of the casting. The first drive motor drives the screw to rotate in the reverse direction, causing the lever to return to its original position, ready for the next casting to be moved.

[0012] Preferably, an upper sliding groove is formed on the top wall of the feeding hole, and a lower sliding groove is formed on the bottom wall of the feeding hole. The protective mechanism includes an upper dustproof plate that can abut against the top surface of the first conveyor belt and a lower dustproof plate that can abut against the bottom surface of the first conveyor belt.

During the processing of the casting, the upper dustproof plate is driven to abut against the top surface of the first conveyor belt, and the lower dustproof plate is driven to abut against the bottom surface of the first conveyor belt, which facilitates the sealing of the feeding hole and thus prevents dust from drifting out of the protective box from the feeding hole.

[0014] Preferably, the protective mechanism includes a second infrared sensor for detecting whether the casting on the first conveyor belt is close to the feed hole and a left dust blower for preventing dust from flying into the first conveying pipe. The second infrared sensor and the left dust blower are disposed in the first conveying pipe, with the second infrared sensor close to the feed hole and the left dust blower close to the first conveyor belt.

[0015] By adopting the above technical solution, the second infrared sensor and the left dust blower are set inside the first conveying pipe. The second infrared sensor is close to the feeding hole, and the left dust blower is close to the first conveyor belt. When the second infrared sensor detects the casting, it means that the casting has approached the feeding hole. At this time, the upper dustproof plate and the lower dustproof plate are driven away from the first conveyor belt, and the left dust blower is driven to blow air towards the feeding hole. That is, during the process of conveying the casting into the protective box, the left dust blower gives the feeding hole a certain amount of air force to prevent dust from drifting out of the feeding hole.

[0016] Preferably, the protective box has a material conveying hole on its other side in the width direction.

The conveying direction of the second conveyor belt is perpendicular to the conveying direction of the first conveyor belt. The first conveyor belt, the third infrared sensor, and the push rod are set inside the second material conveying pipe. During the process of conveying the finished casting, the casting is conveyed out of the protective box with the first conveyor belt. When the third infrared sensor detects the casting, it drives the push rod to push the casting from the first conveyor belt to the second conveyor belt, which facilitates the conveying of the finished casting.

The upper dust blocking plate is vertically slidably disposed in the upper sliding groove, and the lower dust blocking plate is vertically slidably disposed in the lower sliding groove.

[0019] By adopting the above technical solution, an upper sliding groove is provided on the top wall of the conveying hole, and an upper dust blocking plate is vertically slidably installed in the upper sliding groove. A lower sliding groove is provided on the bottom wall of the conveying hole, and a lower dust blocking plate is vertically slidably installed in the lower sliding groove, which facilitates sealing the conveying hole and thus prevents dust from drifting out of the protective box from the conveying hole.

The switch is located inside the protective box and is close to the conveying hole. The right dust blower is located inside the second conveying pipe and is close to the first conveyor belt.

[0021] By adopting the above technical solution, the switch is set inside the protective box, near the material conveying hole. The right dust blower is set inside the second material conveying pipe, near the first conveyor belt. After the casting is processed, the worker places it on the first conveyor belt, presses the switch to control the upper and lower dust blocking plates to slide away from each other, so that the casting is conveyed along the first conveyor belt. At the same time, the right dust blower is driven to blow air towards the material conveying hole. That is, during the process of sending the casting out of the protective box, the right dust blower provides a certain amount of air force to the material conveying hole to prevent dust from drifting out of the material conveying hole.

[0022] Preferably, a through hole is provided on one side of the protective box in the width direction, and a dustproof cotton ring is provided on the inner wall of the through hole.

[0056] Reference Figure 2 , Figure 3 and Figure 4 As shown, the second infrared sensor 66 and the left dust blower 67 are installed inside the first conveying pipe 41. The second infrared sensor 66 is close to the feeding hole 37, and the left dust blower 67 is close to the first conveyor belt 42. When the second infrared sensor 66 detects the casting, it means that the casting has approached the feeding hole 37. At this time, the upper dustproof plate 61 and the lower dustproof plate 62 are driven away from the first conveyor belt 42, and the left dust blower 67 is driven to blow air into the feeding hole 37. That is, during the process of conveying the casting into the protective box 3, the left dust blower 67 provides a certain amount of air force to the feeding hole 37 to prevent dust from drifting out of the feeding hole 37.

[0057] Reference Figure 2 , Figure 3 and Figure 4 As shown, the switch is located inside the protective box 3, near the material conveying hole 38. The right dust blower 68 is located inside the second material conveying pipe 53, near the first conveyor belt 52. After the worker finishes processing the casting and places it on the first conveyor belt 52, he presses the switch to control the upper dust blocking plate 63 and the lower dust blocking plate 64 to slide away from each other, so that the casting is conveyed along the first conveyor belt 52. At the same time, the right dust blower 68 is driven to blow air into the material conveying hole 38. That is, during the process of sending the casting out of the protective box 3, the right dust blower 68 provides a certain amount of air force to the material conveying hole 38 to prevent dust from drifting out of the material conveying hole 38.

[0058] The implementation principle of a grinding device for casting processing in this application embodiment is as follows: During the grinding process, workers wearing protective gloves 36 reach into the protective box 3. The first conveyor belt 42 and the second conveyor belt 44 transport the unprocessed casting into the protective box 3. Workers then use an angle grinder 1 to grind the casting. The upper dustproof plate 61, lower dustproof plate 62, upper dust barrier 63, and lower dust barrier 64 prevent dust from escaping from the protective box 3. After the casting is ground, the first conveyor belt 52 and the second conveyor belt 54 transport the processed casting out of the protective box 3. The telescopic water pipe 33 can be connected to an external water source and spray water through the water nozzle 34 to clean the dust inside the protective box 3. The water flow can flow through the flow hole 21 into the water tank 2 and then out of the protective box 3 through the water outlet pipe 22, which facilitates the cleaning of dust inside the protective box 3, reduces dust dispersion pollution, and creates a good working environment for workers.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
