Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a casting riser grinding device. Background Technology

[0002] Riser is a common structure in casting production. Its function is to provide additional molten metal during casting to compensate for shrinkage during solidification and ensure casting quality. However, after the casting is formed, the riser area usually needs to be ground to remove excess metal and ensure that the casting meets the specified dimensional accuracy and surface quality requirements. Traditional casting riser grinding generates a large amount of metal dust during the grinding process. This dust will permeate the surrounding environment and cause serious harm to the health of workers, such as causing respiratory diseases. During the polishing process, the limiting of polishing and the movement of polishing parts generally require multiple drive sources for control, which increases the overall equipment cost. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a casting riser grinding device. When in use, this grinding device can prevent grinding dust from affecting the surrounding environment. In addition, by using a limiting grinding component, the casting can be limited while the workpiece is being moved before grinding, ensuring stability during grinding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A casting riser grinding device includes a housing; a limiting grinding assembly, the limiting grinding assembly including a cylinder installed at the bottom of a base frame, the telescopic end of the cylinder being fixedly connected to a dustproof electric slide rail, the sliding part of the dustproof electric slide rail being equipped with the grinding assembly, a placement box being detachably installed on the top inner side of the housing, the placement box being a box structure with an open front side, a grinding through groove being opened at the bottom inner side of the placement box, guide blocks being installed on both the left and right sides of the dustproof electric slide rail, and limiting strips being detachably installed on the front side of both guide blocks; and a dust suction mechanism installed on the rear side of the housing.

[0005] Preferably, two guide rods are symmetrically fixedly connected to the inner bottom of the housing, and both guide rods pass through the corresponding guide blocks and are slidably connected.

[0006] Preferably, a base frame is installed at the lower end of the housing, and a sealed door is installed on the front side of the housing.

[0007] Preferably, the casting body is placed inside the placement box, the rear side of the casting body is in contact with the rear sidewall of the placement box, and the front side of the casting body is in contact with two limiting strips.

[0008] Preferably, the dust collection mechanism includes a filter box installed on the rear side of the housing, an air collecting hood communicating with the interior of the housing is installed on the rear side of the housing, the air collecting hood is connected to the filter box through a connecting pipe, a negative pressure pump is installed on the rear side of the filter box, and the air inlet of the negative pressure pump is connected to the rear space of the filter box.

[0009] Preferably, an observation port is provided on the front side wall of the housing.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. Place the rectangular casting body into the placement box, ensuring that its rear and left / right side walls are aligned with the corresponding parts of the placement box, and its front side contacts the limiting strip, with the riser located within the grinding groove. When the cylinder operates, the limiting strip moves upward synchronously to block and limit movement, effectively preventing the casting from shaking during grinding and ensuring stable grinding.

[0011] 2. The negative pressure pump of the dust collection mechanism creates negative pressure in the filter box, drawing dust from inside the housing through the air collection hood into the filter box for removal. This effectively reduces dust in the workshop, improves the working environment, and minimizes the health hazards of dust to operators.

[0012] 3. The observation port allows for monitoring of the grinding process, facilitating timely assessment of progress and quality. During operation, the dust extraction mechanism generates a front-to-back airflow through the observation port, preventing dust leakage. Simultaneously, any unextracted dust falls due to gravity and does not adhere to the casting, resulting in a clean casting after grinding, which facilitates subsequent processing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A casting riser grinding device includes a housing 2, a base frame 1 installed at the lower end of the housing 2, a sealing door 4 installed on the front side of the housing 2, and an observation port 3 opened on the front side wall of the housing 2. Through the observation port 3, not only can the grinding situation be observed, but also gas can be replenished by the observation port 3 when the subsequent dust collection mechanism is running (i.e., an airflow from front to back is generated at the observation port 3). In this way, it can also be ensured that dust will not leak through the observation port 3. It also includes a limiting grinding assembly, which includes a cylinder 11 installed at the bottom of the base frame 1. The cylinder 11 is model MHK2-16D and has good dustproof performance. The telescopic end of the cylinder 11 is fixedly connected to a dustproof electric slide rail 12, model HGR20HGR15. The sliding part of the dustproof electric slide rail 12 is equipped with a grinding assembly 13. The grinding assembly 13 consists of a motor and a grinding disc. The motor here is a YFB4 series dust explosion-proof motor with good dustproof performance. The grinding disc is connected to the motor output shaft in a detachable manner. The inner top of the housing 2 is detachably equipped with a placement box 8. The placement box 8 is a box structure with the front open. A grinding through groove 10 is opened at the bottom of the placement box 8. Guide blocks 14 are installed on both the left and right sides of the dustproof electric slide rail 12. Limit strips 16 can be detachably installed on the front side of both guide blocks 14. The placement box 8 contains the casting body 9. The rear side of the casting body 9 contacts the rear side wall of the placement box 8, and its left and right side walls also fit against the corresponding inner walls of the placement box 8. The front side of the casting body 9 contacts the two limiting strips 16. The casting body 9 in this solution is a rectangular casting. After the casting is placed into the placement box 8, its riser is located in the grinding groove 10. At this time, the cylinder 11 is first activated to extend and adjust the height of the grinding component 13. During this process, the two limiting strips 16 will also move upward synchronously to block and limit the front side of the casting body 9, ensuring grinding stability. Then, the dustproof electric slide rail 12 is activated to move the grinding component 13 forward. The grinding operation can be performed using the grinding component 13. It should be noted that the above detachable connections are all connected by screws, and different placement boxes 8 and limiting strips 16 can be replaced to meet the limiting requirements of different rectangular castings.

[0017] Two guide rods 15 are symmetrically fixedly connected to the inner bottom of the housing 2. Both guide rods 15 pass through the corresponding guide blocks 14 and are slidably connected. The cooperation between the guide rods 15 and the guide blocks 14 improves the stability of vertical movement.

[0018] It also includes a dust collection mechanism, which is installed on the rear side of the housing 2. The dust collection mechanism includes a filter box 5 installed on the rear side of the housing 2. An air collection hood 7 that communicates with the interior of the housing 2 is installed on the rear side of the housing 2. The air collection hood 7 and the filter box 5 are connected by a connecting pipe. A negative pressure pump 6 is installed on the rear side of the filter box 5. The air inlet of the negative pressure pump 6 is connected to the rear space of the filter box 5. The filter box 5 is equipped with a filter screen. The connection between the connecting pipe and the filter box 5 is located on the front side of the filter screen. The connection between the negative pressure pump 6 and the filter box 5 is located on the rear side of the filter screen. When the negative pressure pump 6 is started, the dust suction operation can be realized. The bottom of the filter box 5 can also be equipped with a maintenance port, which is equipped with a maintenance cover to facilitate subsequent cleaning operations.

[0019] In this invention, a rectangular casting body 9 is placed in a placement box 8 at the top of the housing 2, with the rear side of the casting body 9 in contact with the rear side wall of the placement box 8, the left and right side walls fitting against the corresponding inner walls of the placement box 8, and the front side in contact with two limiting strips 16. At this time, the riser of the casting body 9 is located in the grinding groove 10 opened at the bottom of the placement box 8. The cylinder 11 installed at the bottom of the base frame 1 is activated, and the cylinder 11 extends, driving the dustproof electric slide rail 12 fixedly connected to its telescopic end to rise, thereby adjusting the height of the grinding assembly 13 installed on the sliding part of the dustproof electric slide rail 12. During this process, the limiting strips 16 installed on the front side of the guide blocks 14 on the left and right sides of the dustproof electric slide rail 12 move upward synchronously, blocking and limiting the front side of the casting body 9 to ensure grinding stability. The dustproof electric slide rail 12 is activated, and the sliding part of the dustproof electric slide rail 12 drives the grinding component 13 to move forward. The grinding component 13 is activated at the same time and performs grinding operation on the riser of the casting body 9 through the grinding groove 10. At the same time, the dust collection mechanism installed on the rear side of the housing 2 is activated, and the negative pressure pump 6 of the dust collection mechanism works, creating a negative pressure inside the filter box 5. The dust inside the housing 2 enters the filter box 5 through the air collection hood 7, which is connected to the inside of the housing 2 and to the filter box 5 through a connecting pipe, thus removing the grinding dust. The polishing process can be observed through the observation port 3 on the front side wall of the housing 2. When the dust collection mechanism is running, an airflow from front to back is generated at the observation port 3 to ensure that dust does not leak through the observation port 3; In addition, since the main body 9 of the casting is placed at the top limit, some grinding dust that has not been removed will not adhere to the main body 9 of the casting after falling due to gravity. With this method, the main body 9 of the casting is relatively clean after grinding, which is convenient for entering the next process.
