Description

Technical Field

[0001] The utility model relates to the technical field of casting production, and specifically relates to a surface grinding device for ship castings. Background Art

[0002] Castings are metal formed objects obtained through various casting methods, which involves injecting liquid metal into a pre-prepared mold by pouring, injection, suction or other casting methods. After the casting cools, it needs to go through subsequent processing means such as grinding to obtain an object with a certain shape, size and performance. Especially ship castings, which are specifically used for ships. However, in the existing technology, a large amount of waste chips are generated during the grinding process of castings. These waste chips not only fly and are difficult to collect, increasing the workload of workers, but also adhere to the surface of the castings. During the grinding process, these adhered waste chips are not easy to clean and may have a negative impact on the grinding quality of the castings. Therefore, the design concept of this device is to solve these problems existing in the prior art, improve the grinding efficiency, reduce the influence of waste chips on the surface treatment of castings, and simplify the cleaning process.

When working, the casting is placed in the placement groove on the turntable, and the cylinder drives the clamping plate to fix the casting. The second motor is started to make the grinding disc rotate for grinding. After one side is ground, the third motor is started, and the rotating rod drives the turntable to rotate so that the other side of the casting is aligned with the grinding disc for continuous grinding. The first motor is started, and the transmission rod drives the rotating frame and the guide rod, so that the moving frame reciprocates, and the impact plate intermittently impacts the casting to help the waste chips fall off. The negative pressure fan is started, and the waste chips are sucked into the collection box through the air suction pipe to keep the table top plate clean. During the whole process, the clamping plate and the cylinder ensure the stability of the casting, the spring and the guide block ensure the stability of the moving plate, and the lead screw and the sliding groove allow flexible adjustment of the position of the grinding disc to adapt to the grinding requirements of castings with different lengths.

Detailed implementation mode

[0023] In order to further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be described in further detail below in conjunction with the drawings and the specific implementation mode.

[0024] Refer to Figures 1-7 : A surface grinding device for a ship hull casting, including a table body 1 for carrying the device, a receiving tray 3 for loading the casting is arranged on the table body 1, a fixing component 2 for fixing the casting on the receiving tray 3, and a grinding component 4 for grinding the casting. The fixing component 2 includes a support frame on the table body 1, a motor is arranged on the support frame, the output shaft 21 of the motor passes through the support frame, the output shaft 21 is connected with an upper moving block 22, the upper moving block 22 is placed in a limiting box body 23, the upper moving block 22 is slidably connected with the limiting box body 23, a plurality of limiting grooves 231 are arranged on the side surface of the limiting box body 23, a first rotating block 221 with the same number as the limiting grooves 231 is arranged on the side surface of the upper moving block 22, the first rotating rod 24 is rotationally connected with the upper moving block 22 through the first rotating block 221, the second rotating rod 25 is rotationally connected with the first rotating rod 24, a clamping block 251 is arranged on the second rotating rod 25, the limiting box body 23 is fixedly connected with a lower moving block 26 through a connecting column, a second rotating block 261 is arranged on the lower moving block 26, and the second rotating rod 25 is rotationally connected with the lower moving block 26 through the second rotating block 261.

[0025] The working principle of the hull casting surface grinding device involves the coordinated action of multiple components. First, the device is carried by the table body 1, and a receiving tray 3 is provided on the table body 1 to load the casting. The fixing component 2 is installed on the support frame of the table body 1 and includes a motor and an upper moving block 22 connected thereto. The output shaft 21 of the motor penetrates the support frame and drives the upper moving block 22 to move downward through the sliding connection within the limit box body 23. The side of the limit box body 23 is provided with limit slots 231 corresponding to the number of the first rotating blocks 221 on the side of the upper moving block 22, and these first rotating blocks 221 are rotationally connected to the upper moving block 22 through the limit slots 231. The first rotating rod 24 is connected to these first rotating blocks 221 and is further rotationally connected to the second rotating rod 25, and a clamping block 251 is provided on the second rotating rod 25. The limit box body 23 is fixedly connected to the lower moving block 26 through a connecting column, and a second rotating block 261 is provided on the lower moving block 26, and the second rotating rod 25 is rotationally connected to the lower moving block 26 through the second rotating block 261. When the motor is started, its output shaft 21 first drives the upper moving block 22 and the lower moving block 26 to move downward until the lower moving block 26 contacts the casting on the receiving tray 3. Subsequently, the motor continues to drive the upper moving block 22 to move downward within the limit box body 23, so that the first rotating block 221 drives the first rotating rod 24 to move, and further drives the second rotating rod 25 to move. The second rotating rod 25 is connected to the lower moving block 26 through the second rotating block 261 on the lower moving block 26. Therefore, during the downward movement of the upper moving block 22, the second rotating rod 25 drives the clamping block 251 to clamp and fix the casting, ensuring the stability of the casting during the grinding process. In this way, the entire fixing component 2 realizes the precise fixation of the casting through a series of mechanical transmissions, providing a solid foundation for the subsequent grinding work.

[0026] Refer to Figures 1-5 : The grinding component 4 includes a moving groove 42 opened on the table body 1, a lead screw 43 is provided in the moving groove 42, and a grinding machine 41 is provided above the moving groove 42, and the grinding machine 41 is rotationally connected to the lead screw 43.

[0027] The working principle of the hull casting surface grinding device involves the coordinated action of the grinding component 4. This component is composed of the moving groove 42 on the table body 1, and a lead screw 43 is installed in the moving groove 42, which is the component to realize the precise movement of the grinding machine 41. Above the moving groove 42, the device is equipped with a grinding machine 41, which is rotationally connected to the lead screw 43. When the grinding machine 41 needs to perform grinding operations on the surface of the casting, the rotation of the lead screw 43 drives the grinding machine 41 to move along the moving groove 42, realizing the precise positioning and movement of the grinding machine 41 on the surface of the casting. Through this design, the grinding machine 41 can perform efficient and uniform grinding treatment on the surface of the hull casting, ensuring the grinding quality, and at the same time improving the flexibility and efficiency of the grinding work.

[0028] Refer to Figures 1-7:The table body 1 is provided with a cooling component 5. The cooling component 5 includes a water pump 51 arranged on the tabletop. A water spray pipe 52 is provided on the water pump 51, and the outlet of the water spray pipe 52 faces the grinding position directly.

[0029] A water spray pipe 52 is connected to the water pump 51, and the outlet of the water spray pipe 52 is designed to directly face the grinding position of the casting. During the grinding process, the water pump 51 works to transport the cooling water through the water spray pipe 52 to the grinding area. The outlet position of the water spray pipe 52 ensures that the cooling water can accurately cover the grinding point. This cooling mechanism helps to reduce the heat generated during the grinding process, prevent the casting surface from being affected by overheating and damaging the grinding quality, and also extend the service life of the grinding tool. Through the effective operation of the cooling component 5, the stability of the grinding process and the high-precision requirements for casting processing are ensured.

[0030] Refer to Figures 1-7 :A rotating component 6 is arranged below the table body 1. The rotating component 6 includes a motor arranged below the table body 1, and the rotating shaft 61 of the motor passes through the table body 1 and is fixedly connected to the receiving plate 3.

[0031] The table body 1 is equipped with a motor below. The rotating shaft 61 of this motor is designed to pass through the table body 1 and be fixedly connected to the receiving plate 3. When the motor is started, its rotating shaft 61 will drive the receiving plate 3 to rotate, so that the casting placed on the receiving plate 3 can rotate. This rotating mechanism allows the grinding machine 41 to contact and grind different parts of the casting, achieving an all-round grinding effect. Through the precise control of the motor, the rotation speed and direction of the receiving plate 3 can be adjusted to adapt to different grinding requirements and the operating habits of the operator, improving the grinding efficiency and the quality of the casting surface treatment.

[0032] Refer to Figures 5-7 :A waste liquid pool 7 is arranged on the table body 1. A water outlet hole 71 is provided at the bottom of the waste liquid pool 7. The water outlet hole 71 is connected to the water pump 51 through a water guide pipe 53, and a one-way valve is arranged in the water guide pipe 53.

[0033] The water pump 51 is responsible for pumping out the coolant in the waste liquid pool 7 so that these coolants can be recycled and play their role of cooling again. During the grinding process, the coolant is sprayed onto the casting to reduce the temperature and prevent overheating. The used coolant contains abrasive dust and heat and flows into the waste liquid pool 7. The water pump 51 then pumps out these used coolants and reuses them to cool the casting. Such recycling not only improves the use efficiency of the coolant but also reduces resource waste, contributing to the dual goals of environmental protection and cost-effectiveness.

[0034] Refer to Figures 5-7 :A filter screen 8 is arranged in the waste liquid pool 7.

[0035] The filter screen 8 is installed inside the waste liquid tank 7 and is used to capture and intercept grinding debris, impurities and other solid particles in the waste liquid when the waste liquid flows through. When the water pump 51 pumps the coolant from the waste liquid tank 7, the coolant first passes through the filter screen 8. The pores of the filter screen 8 are small enough to prevent these unwanted particles from being pumped out together with the coolant, thus ensuring that the recycled coolant remains clean and efficient. The setting of the filter screen 8 helps to extend the service life of the coolant, reduce the maintenance cost, and improve the overall cleanliness and efficiency of the grinding process. Regularly cleaning or replacing the filter screen 8 can ensure the continuous effectiveness of the filtering function of the waste liquid tank 7.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
