Description

Technical Field

[0001] This utility model belongs to the technical field of grinding and processing equipment, specifically relating to a grinding device for processing water pump impellers. Background Technology

[0002] The impeller is the core component of a water pump and a major factor affecting its efficiency. It can be divided into single-suction and double-suction types, and its shape and size are closely related to the pump's performance. It is usually made of cast iron. Due to the materials and manufacturing process, water pump impellers have burrs after casting, which generally require grinding.

[0003] Currently, according to the Chinese utility model patent with application number "202320640756.7", the grinding process of existing water pump impellers is usually completed by grinding equipment. However, when existing grinding equipment is used for grinding, the burrs on the water pump impeller are easily ground, which can generate flying iron filings. At the same time, the iron filings are at a high temperature due to friction. The flying high-temperature iron filings can easily cause harm to the operators, resulting in poor safety during the grinding process of water pump impellers. Utility Model Content

[0028] An embodiment of this utility model provides a grinding device for processing water pump impellers, comprising: a worktable 1, on which a clamping mechanism 2 is provided, the clamping mechanism 2 being used to clamp the water pump impeller and drive the water pump impeller to rotate around the axial direction; a protective mechanism 3, which is installed on the side wall of the worktable 1 and is used to move up and down along the side wall of the worktable 1, and when the protective mechanism 3 moves to the upper end of the worktable 1, the protective mechanism 3 is arranged in a ring around the clamping mechanism 2; and a support mechanism 4, which is located on one side of the worktable 1 and is drivenly connected to a grinding mechanism 5 located above the clamping mechanism 2, the support mechanism 4 being used to drive the grinding mechanism 5 to approach or move away from the clamping mechanism 2, and the grinding mechanism 5 being used to grind the water pump impeller.

[0029] Specifically, such as Figure 1 As shown, the axial direction of the water pump impeller is the Z-axis direction.

[0030] In this embodiment, as Figure 1As shown, a grinding device for processing water pump impellers is composed of a worktable 1, a clamping mechanism 2, a protective mechanism 3, a support mechanism 4, and a grinding mechanism 5. The worktable 1 serves as the supporting structure for the entire grinding device, ensuring its stability. The clamping mechanism 2, located on the worktable 1, clamps the water pump impeller, further ensuring its stability on the worktable 1. The support mechanism 4 is positioned on one side of the worktable 1, while the grinding mechanism 5 is positioned above the clamping mechanism 2 and is driven by the support mechanism 4. The support mechanism 4 can drive the grinding mechanism 5 to move closer to or away from the water pump impeller on the clamping mechanism 2, thus enabling the grinding mechanism 5 to grind the water pump impeller. The clamping mechanism 2 can also drive the water pump impeller to rotate around the axial direction. Through the rotation of the water pump impeller and the resulting rotational force, in conjunction with the grinding mechanism 5, the grinding effect and efficiency of the water pump impeller are effectively improved. At the same time, the protective mechanism 3 is installed on the side wall of the workbench 1. The protective mechanism 3 can move up and down along the side wall of the workbench 1. With this arrangement, after the water pump impeller is placed, the protective mechanism 3 can move to the upper end of the workbench 1 and be distributed in a ring around the clamping mechanism 2. When the water pump impeller is being ground and iron filings are generated, the iron filings will be blocked by the protective mechanism 3 and will not fly to the outside of the workbench 1, thereby avoiding the adverse impact of iron filings on the safety of the operator and effectively improving the safety of the water pump impeller grinding process.

[0031] Optionally, the clamping mechanism 2 includes a first rotary drive 21 and a clamping assembly 22. The first rotary drive 21 is mounted on the upper surface of the worktable 1 and is drivenly connected to the clamping assembly 22. The clamping assembly 22 is used to clamp the water pump impeller, and the first rotary drive 21 is used to drive the clamping assembly 22 to rotate, so as to drive the water pump impeller to rotate around the axial direction.

[0032] Specifically, such as Figure 2 As shown, the first rotary drive component 21 is a rotary motor or a servo motor, etc.

[0033] In this optional embodiment, such as Figure 1 and Figure 2 As shown, a clamping mechanism 2 is formed by a first rotary drive 21 and a clamping assembly 22. The first rotary drive 21 is mounted on the upper surface of the worktable 1 and is driven to connect with the clamping assembly 22. Thus, the clamping assembly 22 can be driven to rotate around the vertical direction, i.e., the Z-axis, by the first rotary drive 21. Based on this, the clamping assembly 22 can clamp the water pump impeller. With this configuration, when the clamping assembly 22 is driven to rotate by the first rotary drive 21, it can drive the water pump impeller to rotate around the axial direction, thereby realizing the rotation of the water pump impeller. This facilitates the generation of rotational force to cooperate with the grinding mechanism 5 to improve the grinding effect and grinding efficiency.

[0034] Optionally, the clamping assembly 22 includes a support disk 221, a first telescopic drive member 222, and clamping claws 223. The support disk 221 has a ring structure and is driven to connect with the first rotary drive member 21 so that the first rotary drive member 21 can drive the ring structure to rotate around the axial direction. There are multiple first telescopic drive members 222, which are spaced apart around the axial direction at the axial edge of the support disk 221. Multiple clamping claws 223 are driven to connect with the first telescopic drive members 222 one by one. The first telescopic drive member 222 is used to drive the clamping claws 223 to move closer to or away from the support disk 221 so as to clamp or release the water pump impeller on the support disk 221.

[0035] Specifically, such as Figure 2 As shown, the first telescopic drive component 222 is a telescopic electric cylinder or a telescopic hydraulic cylinder, etc.; the clamping claw 223 is an L-shaped block structure.

[0036] In this optional embodiment, such as Figure 2 As shown, the system comprises a support disk 221, a first telescopic drive component 222, and clamping claws 223. The support disk 221 has a ring structure and is driven to connect with the first rotary drive component 21. This configuration allows the first rotary drive component 21 to drive the support disk 221 to rotate around its axial direction. The water pump impeller can be placed on the support disk 221, and the rotation of the support disk 221 drives the water pump impeller to rotate around its axial direction. Furthermore, multiple first telescopic drive components 222 are spaced apart along the axial edge of the support disk 221. Simultaneously, multiple clamping claws 223 are driven to connect with each first telescopic drive component 222. This configuration allows the first telescopic drive component 222 to drive the clamping claws 223 closer to or further away from the support disk 221, enabling the clamping claws 223 to be released and held, thus ensuring the stability of the water pump impeller on the support disk 221 and facilitating easy assembly and disassembly.

[0038] Specifically, such as Figure 1 As shown, the second telescopic drive component 31 is a telescopic electric cylinder or a telescopic hydraulic cylinder, etc.

[0039] In this optional embodiment, such as Figure 1 and Figure 2As shown, a protective mechanism 3 is formed by a second telescopic drive member 31 and a protective plate 32. A sliding groove 11 is provided on the side wall of the worktable 1. The sliding groove 11 can extend vertically. The second telescopic drive member 31 can be installed in the sliding groove 11, and the protective plate 32 can be arranged around the worktable 1. Its lower end is slidably installed in the sliding groove 11 and drivenly connected to the second telescopic drive member 31. With this arrangement, the second telescopic drive member 31 can drive the lower end of the protective plate 32 to move along the sliding groove 11, thereby realizing the up and down movement of the protective plate 32. This makes the upper end of the protective plate 32 higher than or flush with the clamping mechanism 2, so that the protective plate 32 can rise to protect the grinding process and fall to facilitate the loading and unloading of the water pump impeller.

[0040] Optionally, the protective mechanism 3 also includes a first polishing component 33, which is mounted on the inner wall of the protective plate 32 and is used to move toward or away from the clamping mechanism 2.

The first polishing component 33 is installed on the inner wall of the protective plate 32 and can move toward or away from the clamping mechanism 2. With this configuration, when the water pump impeller rotates under the drive of the clamping mechanism 2, the first polishing component 33 can move toward the clamping mechanism 2, so that the first polishing component 33 contacts the water pump impeller. Under the action of the rotational force of the water pump impeller, the first polishing component 33 polishes the side of the water pump impeller. In conjunction with the polishing mechanism 5, it effectively improves the polishing effect and polishing efficiency of the water pump impeller.

[0042] Optionally, the first grinding assembly 33 includes a second rotary drive 331, a third telescopic drive 332, and a first grinding head 333.

The third telescopic drive 332 is used to drive the first grinding head 333 to move closer to or away from the water pump impeller clamped on the clamping mechanism 2 in the horizontal direction.

[0043] Specifically, such as Figure 1 As shown, the second rotary drive component 331 is a rotary motor or servo motor, etc., and the third telescopic drive component 332 is a telescopic hydraulic cylinder or telescopic electric cylinder, etc.

[0044] In this optional embodiment, such as Figure 1 and Figure 2As shown, a first grinding assembly 33 is formed by a second rotary drive 331, a third telescopic drive 332, and a first grinding head 333. The second rotary drive 331 is mounted on the inner wall of the protective plate 32 and is driven to connect with the third telescopic drive 332. The third telescopic drive 332 is driven to connect with the first grinding head 333. With this configuration, the second rotary drive 331 can drive the third telescopic drive 332 to rotate horizontally, thereby driving the first grinding head 333 to rotate around the central axis. The third telescopic drive 332 can drive the first grinding head 333 to move horizontally closer to or away from the water pump impeller clamped on the clamping mechanism 2. When the first grinding head 333 approaches the water pump impeller, the rotation of the first grinding head 333 can achieve grinding of the water pump impeller. This can be combined with the rotational force of the water pump impeller to improve grinding efficiency and grinding effect.

The lower end of the frame 41 is mounted on one side of the workbench 1 via the fourth telescopic drive member 42. The upper end of the frame 41 is located above the clamping mechanism 2 and is connected to the grinding mechanism 5. The fourth telescopic drive member 42 is used to drive the frame 41 to move up and down, so as to drive the grinding mechanism 5 to move closer to or away from the clamping mechanism 2 in the vertical direction.

Meanwhile, the upper end of the frame 41 is located above the clamping mechanism 2 and is connected to the grinding mechanism 5, thereby ensuring the positional stability of the grinding mechanism 5. Based on this, the fourth telescopic drive 42 can drive the frame 41 to move up and down, thereby causing the grinding mechanism 5 to move closer to or away from the clamping mechanism 2 in the vertical direction, making it easier for the grinding mechanism 5 to approach the clamping mechanism 2 and grind the water pump impeller on the clamping mechanism 2.
