Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to an auxiliary grinding device for valve processing. Background Art

[0002] As a key control component in the fluid conveying system, the valve is used to open and close the pipeline, control the flow direction, and adjust and control the parameters of the conveying medium. It is widely used in the control of various fluids such as water, steam, oil, gas, mud, corrosive media, liquid metal and radioactive media. In the production and processing of valves, grinding is a crucial link. If there are irregular pits or rust on the surface of the valve, it will directly affect its sealing and flow control capabilities, and then affect the operating efficiency and safety of the entire fluid system. Therefore, grinding the valve with the grinding head on the grinding machine can remove the uneven surface and rusted parts, make the valve surface smooth, improve the passage effect of the fluid, and thus extend the service life of the valve. At present, although the valve manufacturing industry has made certain progress in automation and intelligence, most of the valve grinding processes still require manual auxiliary grinding;

[0003] During the valve processing, a large amount of metal or non-metal debris will be generated when the valve surface is polished. These debris are easy to accumulate on the operating platform that supports the valve, forming deposits, which increases the complexity and inconvenience of subsequent valve processing procedures and hinders the smooth progress of the production process. After completing the valve processing task, it is usually necessary to rely on manual methods to clean up the remaining debris on the platform. This process is time-consuming and labor-intensive, and reduces production efficiency.

[0004] In order to solve the above problems, the present application proposes an auxiliary grinding device for valve processing. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes an auxiliary grinding device for valve processing.

[0006] The utility model provides an auxiliary grinding device for valve processing, comprising a grinding machine base and a grinding head installed on the grinding machine base;

[0007] The grinding machine seat is provided with a bearing platform located below the grinding head, a fixing block is provided at one end of the top of the bearing platform, and a limiting member and a driving member for driving the limiting member to move closer to or away from the fixing block are provided on the bearing platform;

[0008] A mounting groove is provided on one side of the fixed block close to the limiting member, and a dust blowing member for cleaning waste chips on the top of the supporting platform is installed in the mounting groove; an air cylinder member located at the other end of the supporting platform and connected to the limiting member is installed on the grinder seat, and the dust blowing member and the air cylinder member are connected through an air guide pipe.

[0009] Preferably, the limiting member includes a limiting block which is arranged on the top of the bearing table and is driven by a driving member to approach or move away from the fixed block. A plurality of jacks arranged in an array are formed on one side of the limiting block close to the fixed block. Springs are installed in the plurality of jacks, and limiting rods connected to the springs are inserted into the jacks.

[0010] Preferably, the dust blowing member includes a dust blowing pipe which is horizontally installed in the assembly groove on one side of the fixed block close to the limiting member. A plurality of dust blowing nozzles facing the top of the bearing table are connected to the side surface of the dust blowing pipe.

[0011] Preferably, the air cylinder member includes an air cylinder body which is installed on the grinding machine base and is located at the other end of the bearing table. An air chamber is formed in the air cylinder body. A piston portion which passes through one end of the air cylinder body and is connected to the limiting block is slidably arranged in the air chamber. A guide pipe communicated with the air chamber is connected to the other end of the air cylinder body, and one end of the guide pipe far away from the air cylinder body is communicated with one end of the dust blowing pipe.

[0012] Preferably, the piston portion includes a piston body which is slidably arranged in the air chamber. An opening communicated with the air chamber is formed at one end of the air cylinder body. A movable rod which is slidably inserted through the opening and is connected to the limiting block is installed at the end of the piston body.

[0013] Preferably, the driving member includes an electric push rod. A sliding groove is formed on the top of the bearing table. A slider integrally connected to the bottom of the limiting block is slidably connected to the sliding groove. The electric push rod is installed at one end of the bearing table.

[0014] The above technical solution of the present utility model has the following beneficial technical effects:

[0015] By arranging the dust blowing member, the air cylinder member and the guide pipe, the valve to be processed can be placed on the bearing table so that it is located between the fixed block and the limiting member. Then, the limiting member can be driven by the driving member to approach the fixed block, so as to clamp the valve. When the limiting member approaches the fixed block, the air cylinder member is pulled to move for air suction. Subsequently, the valve is processed by the grinding head on the grinding machine base. After the processing is completed, the limiting member can be driven by the driving member to move away from the fixed block to release the locking of the valve. Then, the limiting member immediately pushes the air cylinder member to move, and the gas in the air cylinder member is guided along the guide pipe to the dust blowing member, and the top of the bearing table can be blown by the dust blowing member, so as to effectively blow away the waste chips on the top of the bearing table, prevent the accumulation of waste chips, facilitate the subsequent processing of the valve, and improve the production efficiency.

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] As Figures 1-4 shown, an auxiliary grinding device for valve processing proposed by the present utility model includes a grinding machine base 1 and a grinding head 2 installed on the grinding machine base 1;

[0023] In this embodiment, a bearing table 3 is installed on the grinding machine base 1 at a position below the grinding head 2. One end of the top of the bearing table 3 is provided with a fixing block 4. A limiting member 5 and a driving member for driving the limiting member 5 to approach or move away from the fixing block 4 are installed on the bearing table 3. The limiting member 5 includes a limiting block 51. The limiting block 51 is arranged on the top of the bearing table 3 and is driven by the driving member to approach or move away from the fixing block 4. A plurality of arrayed jacks are opened on the side of the limiting block 51 close to the fixing block 4. Springs 52 are installed in the plurality of jacks, and a limiting rod 53 connected to the spring 52 is inserted into the jack. The driving member includes an electric push rod 9. A sliding groove is opened on the top of the bearing table 3. The bottom of the limiting block 51 is integrally connected with a slider slidably connected to the sliding groove. The electric push rod 9 is installed at one end of the bearing table 3. The slider at the bottom of the limiting block 51 is connected to the electric push rod 9 and is driven by the electric push rod 9 to reciprocate along the sliding groove.

[0024] In this embodiment, an assembly groove is formed on one side of the fixed block 4 close to the limiting member 5, and a dust blowing member 6 for cleaning the waste chips on the top of the bearing table 3 is installed in the assembly groove. The dust blowing member 6 includes a dust blowing pipe 61 which is horizontally installed in the assembly groove on one side of the fixed block 4 close to the limiting member 5, and a plurality of dust blowing nozzles 62 facing the top of the bearing table 3 are connected to the side surface of the dust blowing pipe 61.

[0025] In this embodiment, an air cylinder member 7 is installed on the grinding machine base 1 at the other end of the bearing table 3 and connected to the limiting member 5, and the dust blowing member 6 and the air cylinder member 7 are communicated through an air guide pipe 8. The air cylinder member 7 includes an air cylinder body 71 which is installed on the grinding machine base 1 and located at the other end of the bearing table 3. An air chamber is formed in the air cylinder body 71, and a piston portion 72 which passes through one end of the air cylinder body 71 and is connected to the limiting block 51 is slidably arranged in the air chamber. The other end of the air cylinder body 71 is connected with an air guide pipe 8 communicated with the air chamber, and one end of the air guide pipe 8 far away from the air cylinder body 71 is communicated with one end of the dust blowing pipe 61. The piston portion 72 includes a piston body 721 which is slidably arranged in the air chamber. An opening communicated with the air chamber is formed at one end of the air cylinder body 71, and a movable rod 722 which is slidably arranged through the opening and connected to the limiting block 51 is installed at the end of the piston body 721.

[0026] It should be noted that: the valve to be processed can be placed on the bearing table 3 so that it is located between the fixed block 4 and the limiting block 51, and then the limiting block 51 can be driven to approach the fixed block 4 by the electric push rod 9. The corresponding limiting rod 53 on the limiting block 51 contracts into the jack to compress the spring 52, so as to realize the clamping of the valve. When the limiting block 51 approaches the fixed block 4, the movable rod 722 is pulled to drive the piston body 721 to slide in the air cylinder body 71 to inhale air. Subsequently, the valve is processed by the grinding head 2 on the grinding machine base 1. After the processing is completed, the limiting block 51 can be driven to move away from the fixed block 4 by the electric push rod 9 to release the locking of the valve. The limiting block 51 immediately pushes the piston body 721 connected to the movable rod 722 to move in the air cylinder body 71, and pushes the gas in the air cylinder body 71 along the air guide pipe 8 into the dust blowing pipe 61. The top of the bearing table 3 can be blown by the dust blowing nozzles 62 on the dust blowing pipe 61, and the waste chips on the top of the bearing table 3 can be effectively blown away. This structure is convenient for cleaning the waste chips accumulated on the bearing table 3 during the valve processing, preventing the accumulation of waste chips, facilitating the subsequent processing of the valve, and improving the production efficiency.
