Description

Technical Field

[0001] This application relates to the field of large casting operation platforms, and particularly to a large casting turnover platform. Background Art

[0002] When machining large castings during finish machining, due to their large weight, they are usually machined on both the front and back sides. After one side is machined, the factory will use an overhead crane to lift the large casting to the casting turnover platform for turning over. At the same time, in order to dampen the vibration of the casting, a buffer layer is usually laid on the turnover platform to buffer the impact and vibration when the casting falls.

[0003] However, during the milling finish machining process of large castings, a large amount of cutting fluid is required. After machining, some cutting fluid will remain in the cavity of the casting. When the casting is turned over on the turnover platform, the cutting fluid remaining in the cavity will flow out of the casting cavity onto the ground, resulting in a large amount of waste of cutting fluid and increasing the workload of cleaning. Utility Model Content

[0004] In order to solve the problem that when a large casting is turned over on a turnover platform, the cutting fluid remaining in the cavity of the large casting will directly flow to the ground, causing waste and troublesome cleaning, this application provides a large casting turnover platform.

[0005] The large casting turnover platform provided by this application adopts the following technical solutions:

[0006] A large casting turnover platform includes a horizontally placed platform body. A buffer layer is provided on the top wall of the platform body. The side wall of the platform body is inclined. The area of the top wall of the platform body is smaller than the area of the bottom wall of the platform body. A recovery tank is provided below the platform body. The recovery tank is distributed in a ring shape. The lower side of the side wall of the platform body is aligned with the mouth of the recovery tank. A circulating water pump is provided on the recovery tank. The circulating water pump is used to discharge the recovered cutting fluid in the recovery tank.

[0007] After the large casting is turned over on the platform body, the residual cutting fluid flowing out of the cavity of the casting will first flow onto the top wall of the platform body, then flow along the side wall of the platform body into the recovery tank for recovery, and finally be pumped to the cutting fluid recovery location by the circulating water pump, so that when the casting is turned over, the cutting fluid will not flow randomly onto the ground, and the overall cleaning is more convenient. At the same time, cutting fluid is saved.

[0008] Optionally, fixing piles are provided on the bottom wall of the platform body. The fixing piles are buried in the ground, and the recovery tank is buried in the ground.

[0009] Optionally, the vertical projection of the lower side of the side wall of the platform body is located within the recovery tank.

[0010] Optionally, a filter screen is provided at the mouth of the recovery tank. The filter screen covers the mouth of the recovery tank.

[0011] Optionally, the height of the bottom of one end of the recovery tank is greater than the bottom of the other end corresponding to the one end of the recovery tank, the bottom of the recovery tank is inclined, and the circulating water pump is located at the lower end of the bottom of the recovery tank.

[0012] Optionally, a rib is provided on the upper side of the inner side wall of the recovery trough, the filter screen is embedded in the recovery trough, and the bottom wall of the filter screen is in close contact with the top wall of the rib, the thickness of the filter screen is smaller than the distance between the rib and the top wall of the recovery trough for installation and disassembly of the filter screen, and a baffle is provided on the side of the top wall of the filter screen facing away from the platform, and the baffle is used to prevent iron filings from flowing out of the filter screen.

[0013] Optionally, a curling edge is provided on the upper side of the baffle, and the curling edge is curled toward a side away from the platform body.

[0014] Optionally, the buffer layer includes a plurality of wooden piles parallel to each other, the wooden piles are arranged and laid in the same direction, the wooden piles are connected and fixed to each other by steel bars, and the buffer layer is placed on the top wall of the platform.

[0015] Optionally, a fixing pile is provided on the bottom wall of the platform body, the fixing pile is buried in the ground, and the fixing pile is located within the enclosure of the recovery tank.

[0016] In summary, the present application designs the side walls of the turning table to be inclined, and designs the buffer layer on the top of the table to be made of wooden stakes assembled together. When the cutting fluid in the casting flows down, it will first be divided by the buffer layer, and then flow along the side walls of the table to the recovery tank for recovery. While the filter screen filters the iron filings in the cutting fluid, the baffle blocks the cutting fluid, making it difficult for the cutting fluid to splash onto the ground outside the recovery tank. While the cutting fluid is easy to recover, the filtered iron filings are also difficult to splash onto the ground outside the recovery tank due to the blocking of the baffle. At the same time, compared with the traditional rubber buffer layer, the wooden buffer layer can better buffer and protect the casting by being destroyed itself, and it is also convenient to replace.

[0022] The following will further elaborate on this application Figures 1-3 with reference to the accompanying drawings.

[0023] An embodiment of this application discloses a large casting turning platform. Referring to Figure 1 , it includes a table body 1. The table body 1 is horizontally placed on the ground. The top wall and the bottom wall of the table body 1 are both rectangular. The area of the bottom wall of the table body 1 is larger than the area of the top wall of the table body 1. The side wall of the table body 1 is an inclined plane. A buffer layer is provided on the top wall of the table body 1 to buffer the collision and vibration during the turning of the casting. The buffer layer is formed by arranging wooden piles 21 side by side and then splicing them with steel bars. The buffer layer is placed on the top wall of the tabletop. When the casting is turned over, the wooden buffer layer 2 will protect the casting from collision by its own destruction. At the same time, the cutting fluid flowing down from the casting will be divided by the buffer layer 2 and then flow down along the side wall of the table body 1.

[0024] Referring to Figure 1 , a plurality of fixed piles are integrally provided on the bottom wall of the table body 1. The fixed piles are buried in the ground to fix the table body 1. A recovery tank 3 is provided below the table body 1. The recovery tank 3 is integrally in the shape of a rectangular frame. The table body 1 and the recovery tank 3 are coaxial. The vertical projection of the lower side of the side wall of the table body 1 is located on the bottom of the recovery tank 3. The recovery tank 3 is buried in the ground below the table body 1.

[0025] Referring to Figure 1 , a plurality of mutually spliced filter screens 4 are covered at the mouth of the recovery tank 3. The cutting fluid flowing down from the side wall of the table body 1 is filtered by the filter screen 4 and then falls into the recovery tank 3. The bottom of the recovery tank 3 is inclined. The height of the bottom of the recovery tank 3 at one corner is greater than the height of the bottom of the recovery tank 3 at the other corner opposite to it. The filtered cutting fluid converges along the recovery tank 3 at the lower end of the bottom of the recovery tank 3. A circulating water pump is fixedly installed on the ground at the lower end of the bottom of the recovery tank 3. A water pipe is installed at the water inlet end of the circulating water pump. The water pipe leads to the lower corner of the bottom of the recovery tank 3. The cutting fluid in the recovery tank 3 is recovered by the circulating water pump.

[0026] Referring to Figure 1 , Figure 2 and Figure 3, a retaining edge 5 is welded to the inner sidewall of the recovery tank 3 near its tank opening. The retaining edge 5 is horizontal and arranged along the contour direction of the recovery tank 3, and the filter net 4 is placed on the retaining edge 5 in a fitting manner. At the same time, the thickness of the filter net 4 is less than the distance between the top wall of the retaining edge 5 and the top wall of the recovery tank 3, so that the filter net 4 can be disassembled or installed from the recovery tank 3 more conveniently. And because the top wall of the filter net 4 sinks into the recovery tank 3, the flowing cutting fluid is not likely to overflow onto the ground due to a large quantity.

[0027] Refer to Figure 1 and Figure 2 , a baffle 6 is welded to the top wall of the side of the filter net 4 facing away from the table body 1. The baffle 6 is perpendicular to the mesh surface of the filter net 4 and is arranged along the length direction of the filter net 4. A curled edge 61 is integrally provided on the side of the baffle 6 facing away from the filter plate, and the curled edge 61 curls towards the direction away from the table body 1. The cutting fluid flowing down from the sidewall of the table body 1 will be blocked by the baffle 6 during sputtering. At the same time, the filter net 4 can be disassembled and installed more conveniently through the baffle 6 and the curled edge 61, and the curled edge 61 can prevent the staff from being scratched by the baffle 6.

[0028] The implementation principle of a large casting turning table in an embodiment of the present application is: the cutting fluid is drained into the recovery tank 3 through the sidewall of the table body 1 for recovery.

[0029] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
