Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a grinding equipment for a large water pump. Background Art

[0002] Large water pumps usually work in harsh environments, such as sewage pumping stations, desalination plants, etc. In some connection parts, the pump cover end face refers to the contact surface between the bottom of the pump cover and other parts or equipment. It is very important for the sealing performance and operating efficiency of the water pump. The end face of the pump cover should have a high degree of flatness to ensure a close fit with other parts to achieve a good sealing effect. Grinding the seal installation part with a grinding device can provide a flat installation surface. For example, if the surface of the mechanical seal is uneven, it will cause the seal to fail and cause liquid leakage. By grinding the seal installation surface, the sealing effect can be guaranteed, the liquid in the pump can be prevented from leaking, and the normal operation of the pump can be guaranteed.

[0003] The prior art, such as the Chinese patent "CN218837183U", provides a large-scale component surface treatment device, including a movable base, a first track is provided on the movable base, a processing frame extending upward is slidably provided in the first track, and the processing frame is driven by a first driving mechanism provided on the movable base; a vertical second track is provided on the processing frame, a construction platform is slidably provided in the second track, and the construction platform is driven by a second driving mechanism provided on the processing frame; a material platform is provided on the construction platform, and a grinding motor and a water pump are provided above the material platform. The position of the movable base is pre-adjusted, and the final position of the construction platform is adjusted to correspond to the specific position to be treated, so that the equipment can be operated to reach the target area, which greatly shortens the work efficiency and reduces the risk of direct climbing operations; at the same time, the equipped grinding motor and water pump can meet the work needs of surface treatment.

However, for parts with high requirements for surface flatness, the method of zoned grinding is used. Since the grinding parts themselves will be subject to certain wear during the grinding process, the long-term and large-scale grinding process may cause certain differences between the initial grinding area and the final grinding area, which will affect the sealing of the parts when they are spliced.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. Example

[0022] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the present invention provides a grinding device for a large water pump, including a base 1, a workbench 2 is fixedly connected to the top of the base 1, beams 3 are connected to both sides of the outer wall of the base 1, an adjustment mechanism 4 is arranged below the top of the beam 3 for adjusting the grinding range, a cooling mechanism 5 is arranged above the workbench 2 for reducing the temperature of the grinding area, wherein the adjustment mechanism 4 includes a bracket 40, a rotating rod 41 is rotatably connected to the inner wall of the bracket 40, and the rotating rod 41 extends to the bottom of the bracket 40, a support ring 42 is arranged below the rotating rod 41, and a three-pronged sliding rod 4 is rotatably connected to the bottom of the support ring 42 4. The outer wall of each bifurcated slide bar on the three-pronged slide bar 44 is a slide bar 451, the inner wall of the slide bar 451 is rotatably connected with a rotating cylinder 452, the bottom of the rotating cylinder 452 is fixedly connected with a grinding ring 45, the inner wall of the support ring 42 is fixedly connected with three synchronous slideways 43, and the inner walls of the three synchronous slideways 43 are respectively slidably connected with the rotating cylinder 452 at corresponding positions, the outer wall of the rotating rod 41 is fixedly sleeved with a first bevel gear 49, the outer wall of the first bevel gear 49 is meshedly connected with a second bevel gear 491, and the top of the crossbeam 3 is fixedly connected with a servo motor 492 for driving the second bevel gear 491 to rotate.

[0023] Furthermore, by starting the servo motor 492 to drive the second bevel gear 491 to rotate, the meshing first bevel gear 49 drives the rotating rod 41 to rotate, thereby driving the grinding ring 45 below the rotating rod 41 to rotate in a circular path, so as to facilitate the grinding of the spliced ​​end faces of the parts. By the rotation of the three-pronged slide bar 44 below the support ring 42, each synchronous slideway 43 will squeeze the rotating drum 452 above the grinding ring 45 at the corresponding position, so that the three rotating drums 452 respectively drive the grinding ring 45 below to move synchronously, so as to facilitate the adjustment of the diameter of the grinding circular path, so as to facilitate the grinding of parts of different sizes. In addition, this method of grinding with a circular path can ensure the consistency of the grinding state in different areas during large-scale grinding. Example

[0024] See also Figure 5 As shown, the bottom of the rotating rod 41 is fixedly connected to the inner rod 411, the outer wall of the inner rod 411 is radially slidably connected to the outer rod 412, the top of the outer wall of the inner rod 411 is fixedly sleeved with a triangular plate 413, the bottom of the triangular plate 413 is fixedly connected to the electric telescopic rod 414, and the bottom of the electric telescopic rod 414 is fixedly connected to the top of the support ring 42.

[0025] Furthermore, the outer rod 412 connected to the support ring 42 is driven to slide on the outer wall of the inner rod 411 by the electric telescopic rod 414, so as to facilitate the height adjustment of the grinding ring 45 under the corresponding support ring 42, so as to facilitate the adjustment of the grinding depth. Example

[0026] See also Figure 6 As shown, a threaded rod 46 is rotatably connected to the three-pronged slide rod 44, and the threaded rod 46 is arranged parallel to one of the forked slide rods of the three-pronged slide rod 44. A threaded block 47 is threadedly connected to the outer wall of the threaded rod 46, and the threaded block 47 is fixedly connected to the slider 451 at the corresponding position.

[0027] Furthermore, when it is necessary to adjust the grinding of the end faces of parts of different sizes, the threaded rod 46 is rotated and the connection relationship between the three-pronged slide bar 44 and the slider 451 is used to perform relative limiting, so that the grinding ring 45 under the slider 451 can be driven to slide on the three-pronged slide bar 44 through the threaded block 47, so as to facilitate the adjustment of the grinding range of the grinding ring 45. Example

[0028] See also Figure 3 , Figure 4 , Figure 5 As shown, the cooling mechanism 5 includes a pressurizing chamber 51, which is fixedly connected below the top of the beam 3 and outside the rotating rod 41, and the pressurizing chamber 51 is connected to the inside of the base 1 through a water pipe 50. The outer wall of the rotating rod 41 is located inside the pressurizing chamber 51 and is fixedly sleeved with a first turbine 52. The bottom of the pressurizing chamber 51 is rotatably connected to a swivel 53, and the bottom of the swivel 53 is fixedly connected to three pressurizing pipes 54, and the three pressurizing pipes 54 are respectively fixedly connected to the top of the rotating drum 452 at corresponding positions.

[0029] Furthermore, the rotating rod 41 drives the grinding ring 45 below the supporting ring 42 to rotate, thereby driving the first turbine 52 in the pressurizing chamber 51 to rotate, so that negative pressure is generated inside the pressurizing chamber 51, and the coolant inside the base 1 is extracted through the water pipe 50, and then injected into the rotating drum 452 through the pressurizing pipe 54, so as to facilitate spraying the grinding position corresponding to the grinding ring 45, so as to reduce the temperature of the parts and the grinding ring 45 and avoid overheating and burning. Example

[0030] See also Figure 7 As shown, a plurality of spray holes 55 are fixedly connected to the bottom of the rotating drum 452 and are distributed in a circular array for spraying coolant. The spray holes 55 are arranged in an inclined shape, and a second turbine 56 is fixedly connected to the inner wall of the rotating drum 452 .

[0031] Furthermore, when the coolant is injected into the drum 452 and passes through the second turbine 56, the potential energy of the liquid flow will drive the drum 452 connected to the second turbine 56 to rotate, thereby driving the grinding ring 45 to rotate, so that the grinding ring 45 can rotate on its own while rotating in a circular path, which can effectively improve the grinding efficiency, and the rotation of the drum 452 will cause the spray hole 55 to rotate together, so that the spray hole 55 can not only spray coolant for cooling, but also flush the powder debris generated by the grinding ring 45 on the surface of the part to avoid excessive accumulation of powder debris that will affect the effect of the grinding ring 45. Example

[0032] See also Figure 2 As shown, a filter plate 57 is fixedly connected to the inner wall of the base 1, and the filter plate 57 is inclined. A filter frame 58 is slidably connected to the position below the inclined surface of the filter plate 57.

[0033] Furthermore, the coolant after flushing will flow back from the workbench 2 to the base 1, and the powder debris generated by grinding will be filtered and intercepted by the filter plate 57, so that the coolant can be recycled. Since the filter plate 57 is set at an angle, the intercepted powder debris will be flushed into the filter frame 58 for collection, so as to facilitate centralized cleaning later.

[0034] How it works When in use, the servo motor 492 is started to drive the second bevel gear 491 to rotate, and the meshed first bevel gear 49 drives the rotating rod 41 to rotate, thereby driving the grinding ring 45 below the rotating rod 41 to rotate in a circular path, so as to facilitate the grinding of the spliced ​​end faces of the parts. When it is necessary to adjust the end faces of parts of different sizes, the threaded rod 46 is rotated, and the connection relationship between the three-pronged sliding rod 44 and the slider 451 is relatively limited, so that the grinding ring 45 below the slider 451 is driven to slide on the three-pronged sliding rod 44 through the threaded block 47, and each synchronous slideway 43 will adjust the grinding ring 45 at the corresponding position. The rotating drum 452 of the square generates extrusion, so that the three rotating drums 452 respectively drive the grinding ring 45 below to move synchronously, so as to facilitate the adjustment of the diameter of the grinding annular path, so as to facilitate the grinding of parts of different sizes. In addition, this method of grinding by the annular path ensures the consistency of the grinding state of different areas during large-scale grinding. The outer rod 412 connected to the support ring 42 is driven to slide on the outer wall of the inner rod 411 by the electric telescopic rod 414, so as to facilitate the height adjustment of the grinding ring 45 below the corresponding support ring 42, so as to facilitate the adjustment of the grinding depth. The rotating rod 41 drives the support ring 4 2, the grinding ring 45 below rotates, thereby driving the first turbine 52 in the pressurizing chamber 51 to rotate, so that negative pressure is generated inside the pressurizing chamber 51, and the coolant inside the base 1 is extracted through the water pipe 50, and then injected into the rotating drum 452 through the pressurizing pipe 54, so as to facilitate spraying the grinding position corresponding to the grinding ring 45, so as to reduce the temperature of the parts and the grinding ring 45, and avoid overheating and burning. When the coolant is injected into the rotating drum 452 and passes through the second turbine 56, the potential energy of the liquid flow will drive the rotating drum 452 connected to the second turbine 56 to rotate, thereby driving the grinding ring 45 to rotate, so that the grinding ring 45 performs a circular path. While rotating the rotating drum 452, it will also rotate on its own, which can effectively improve the efficiency of grinding, and the rotation of the rotating drum 452 will cause the liquid spray hole 55 to rotate together, so that the liquid spray hole 55 can not only spray out coolant for cooling, but also rinse the powder debris generated by the grinding ring 45 on the surface of the part. The coolant after rinsing will flow back from the workbench 2 to the base 1, and the powder debris generated by grinding will be filtered and intercepted by the filter plate 57, so that the coolant can be recycled. Since the filter plate 57 is inclined, the intercepted powder debris will be flushed into the filter frame 58 for collection, so as to facilitate centralized cleaning later.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
