[0009] The upper end of the housing is equipped with a multi-station drive assembly for driving multiple sets of rotating support assemblies to move sequentially between the abrasive flow assembly and the centrifugal drive assembly.

[0010] The multi-station drive assembly is equipped with rotating support components at equal intervals for placing impellers, cooperating with the grinding flow assembly to polish the impellers, and cooperating with the centrifugal drive assembly to centrifuge and discharge the residual grinding flow liquid in the impellers.

[0011] The housing is equipped with a polishing flow assembly for polishing the impeller in conjunction with each rotating support assembly;

[0012] The housing is also equipped with a centrifugal drive assembly for cooperating with each rotating support assembly to centrifuge and discharge the residual grinding fluid in the impeller.

[0013] The abrasive flow assembly includes a second support frame, a telescopic cover assembly, an abrasive flow circulation assembly, and a U-shaped guide channel. The telescopic cover assembly is installed on the second support frame, which is fixedly installed on the housing. The telescopic cover assembly covers the rotating support assembly, sealing the top opening of the rotating support assembly. The abrasive flow is circulated through the abrasive flow circulation assembly to polish the impeller. The U-shaped guide channel is fixedly installed on the housing and is located below the movement trajectory of the impeller.

[0014] Furthermore, the grinding fluid circulation assembly includes a sleeve, a liquid pump, a collection tank, a straight pipe, a straight hole, and a liquid inlet; the liquid pump is fixedly installed on the side wall of the housing, the liquid inlet end of the liquid pump is connected to the collection tank, the liquid outlet end of the liquid pump is fixedly connected to one end of the sleeve, the collection tank is fixedly installed inside the housing, the straight pipe is fixedly installed on the inner top of the housing and penetrates the housing, the bottom of the straight pipe is located inside the collection tank, the other end of the sleeve is fixedly installed on the second support frame, and the other end of the sleeve is connected to the telescopic cover assembly, the straight hole is opened on the rotating support assembly, and the rotating support assembly is also provided with several liquid inlets for connecting the rotating support assembly and the straight hole.

[0016] Furthermore, when the rotating support assembly rotates clockwise, the front end of the U-shaped guide channel is higher than the rear end, and both ends of the U-shaped guide channel are blocked; the hole at the top of the straight pipe is located inside the U-shaped guide channel and is located on the lower side of the U-shaped guide channel.

[0017] Furthermore, the rotating support assembly includes a lower outer cover, a pad, a column, a key block, a rotating shaft, a driven wheel, and a support bearing. The rotating shaft is fixedly installed at the bottom of the lower outer cover, with a straight hole on the rotating shaft that penetrates the multi-station drive assembly. The liquid inlet is located inside the lower outer cover. The top of the rotating shaft is located inside the lower outer cover, and a pad is fixedly installed on the top of the rotating shaft. A column that mates with the impeller is fixedly installed at the upper end of the pad. A key block that mates with the impeller is fixedly installed on the side wall of the column. The rotating shaft and the multi-station drive assembly are rotatably connected via the support bearing. A driven wheel that mates with the centrifugal drive assembly is fixedly connected to the rotating shaft.

[0018] Furthermore, the centrifugal drive assembly includes a drive wheel, a second motor, a fixed plate, a guide rail assembly, and a first cylinder; the first cylinder is fixedly installed on the upper end of the housing, the drive end of the first cylinder is fixedly connected to the fixed plate, the second motor is fixedly installed on the fixed plate, and the drive end of the second motor is fixedly connected to the drive wheel; when the drive wheel moves to contact the driven wheel, it drives the driven wheel to rotate.

[0019] Furthermore, the fixing plate is slidably connected to the upper end of the housing via a guide rail assembly.

[0020] Furthermore, the multi-station drive assembly includes a synchronous pulley, a straight shaft, an annular guide rail, a connecting plate, a synchronous belt, and a drive motor. The drive motor is fixedly installed inside the housing. Straight shafts are rotatably installed on both the left and right sides of the upper end of the housing. The bottom of one straight shaft is fixedly connected to the drive end of the drive motor. The upper ends of the two straight shafts are fixedly connected to synchronous pulleys.

The lower end of each connecting plate is fixedly connected to a sliding block. The sliding block is slidably installed on the annular guide rail. The annular guide rail is fixedly installed on the upper part of the housing.

[0021] Furthermore, the lower ends of each rotating shaft are rotatably mounted on each connecting plate via support bearings.

[0022] A method for using an impeller polishing device that facilitates positioning includes the following steps:

[0023] 1. The impeller is placed on the pad and inserted into the column and key block;

[0024] 2. The drive motor drives the straight shaft to rotate intermittently, the straight shaft drives the synchronous belt to rotate, the synchronous belt drives the connecting plate to rotate, the connecting plate drives the sliding block to move along the annular guide rail, and the connecting plate drives the rotating support assembly to move at equal intervals, so that the rotating support assembly moves sequentially to the bottom of the inner cover; at the same time, when the rotating support assembly drives the impeller to move, the U-shaped guide channel can continuously receive the dripping grinding fluid and automatically guide it to the straight pipe.

[0025] 3. Start the second cylinder to drive the horizontal plate to move downward. The horizontal plate drives the slide tube to slide downward along the sleeve. The horizontal plate drives the inner cover to move downward through the connecting cover and cover the lower outer cover. Then start the liquid pump to transport the grinding fluid in the collection tank through the sleeve, slide tube, connecting cover and inner cover to the impeller in the rotating support assembly to polish the impeller. Then the grinding fluid flows out from the impeller and enters the straight hole through the liquid inlet. At this time, the U-shaped guide channel is located below the straight hole. Preferably, the straight pipe is located directly below the straight hole. The grinding fluid flows out from the straight hole to the U-shaped guide channel and the straight pipe, and then flows back to the collection tank through the straight pipe to realize the circulation process.

[0026] 4. After the impeller polishing is completed, the first cylinder is started to drive the fixed plate to move under the limiting action of the guide rail assembly. The fixed plate drives the second motor and drive wheel to move. When the drive wheel moves to contact the driven wheel, the second motor is started to drive the drive wheel to rotate. The drive wheel drives the driven wheel to rotate. The driven wheel drives the rotating shaft to rotate. The rotating shaft drives the lower outer cover and the pad to rotate. When the lower outer cover rotates, it slides against the inner cover. The pad drives the impeller to rotate centrifugally through the column and key block, throwing out the grinding fluid inside the impeller.

[0027] Beneficial effects

[0028] The upper end of the pad of the present invention is fixedly installed with a column that is inserted into the impeller, and a key block that is inserted into the side wall of the column is fixedly installed, which is conducive to ensuring the rapid positioning and placement of the impeller.

[0029] This invention uses a drive motor to drive a straight shaft to rotate intermittently, which in turn drives a synchronous belt to rotate. The synchronous belt then drives a connecting plate to rotate, which in turn drives a sliding block to move along a circular guide rail. The connecting plate also drives the rotating support components to move at equal intervals, so that each set of rotating support components moves sequentially to the position between the abrasive flow component and the centrifugal drive component. This invention can achieve continuous processing of batch impellers with higher efficiency.

[0030] This invention uses a multi-station drive assembly to move a rotating support assembly sequentially to below the inner cover. A second cylinder is activated, causing a horizontal plate to move downwards. The horizontal plate then moves a sliding tube downwards along a sleeve. The horizontal plate, through a connecting cover, moves the inner cover downwards to cover the rotating support assembly. A liquid pump is then activated, transporting the grinding fluid from the collection tank through the sleeve, sliding tube, connecting cover, and inner cover to the impeller in the rotating support assembly. The impeller is polished, and the grinding fluid flows out from the impeller and through the inlet into a straight hole. At this point, a U-shaped guide channel is located below the straight hole. Preferably, the straight pipe is located directly below the straight hole. The grinding fluid flows from the straight hole to the U-shaped guide channel and the straight pipe, and then flows back into the collection tank through the straight pipe, achieving a circulation process. Simultaneously, by setting up the U-shaped guide channel, as the rotating support assembly moves the impeller, the U-shaped guide channel continuously receives the dripping grinding fluid, preventing the grinding fluid from dripping onto the worktable and requiring cleaning. Furthermore, the higher front end and lower rear end of the U-shaped guide channel automatically guides the fluid to the straight pipe.

[0031] After the impeller of this invention is polished, it contacts the driven wheel through the centrifugal drive assembly and drives the driven wheel to rotate. The driven wheel drives the rotating shaft to rotate, and the rotating shaft drives the lower outer cover and the pad to rotate. When the lower outer cover rotates, it slides against the inner cover. The pad drives the impeller to rotate centrifugally through the column and key block, which throws out the grinding fluid inside the impeller, avoiding the presence of grinding fluid residue inside the impeller and eliminating the need for subsequent cleaning.

The telescopic cover assembly is installed on the second support frame 52, which is fixedly installed on the housing 1. The telescopic cover assembly covers the rotating support assembly 3, sealing the top opening of the rotating support assembly 3. The abrasive flow fluid circulates through the abrasive flow fluid circulation assembly, thereby polishing the impeller. The U-shaped guide channel 54 is fixedly installed on the housing 1 and is located below the movement trajectory of the impeller.

[0055] The grinding fluid circulation assembly includes a sleeve 53, a liquid pump 55, a collection tank 58, a straight pipe 59, a straight hole 511, and a liquid inlet 513. The liquid pump 55 is fixedly installed on the side wall of the housing 1. The liquid inlet end of the liquid pump 55 is connected to the collection tank 58, and the liquid outlet end of the liquid pump 55 is fixedly connected to one end of the sleeve 53. The collection tank 58 is fixedly installed inside the housing 1. The straight pipe 59 is fixedly installed on the inner top of the housing 1 and penetrates the housing 1.

[0057] When the rotating support assembly 3 rotates clockwise, the front end of the U-shaped guide channel 54 is higher and the rear end is lower, and both ends of the U-shaped guide channel 54 are blocked; the hole at the top of the straight pipe 59 is located inside the U-shaped guide channel 54 and is located on the lower side of the U-shaped guide channel 54.

[0058] The multi-station drive assembly 2 drives the rotating support assembly 3 to move sequentially below the inner cover 510. The second cylinder 51 is then activated, causing the horizontal plate 57 to move downwards. The horizontal plate 57 drives the slide tube 56 to slide downwards along the sleeve 53. The horizontal plate 57, through the connecting cover 512, drives the inner cover 510 downwards to cover the rotating support assembly 3. Then, the liquid pump 55 is activated, transporting the grinding fluid from the collection tank 58 through the sleeve 53, slide tube 56, connecting cover 512, and inner cover 510 to the impeller in the rotating support assembly 3 for polishing. The grinding fluid then flows out of the impeller and enters the straight... Inside the hole 511, the U-shaped guide channel 54 is located below the straight hole 511. Preferably, the straight pipe 59 is located directly below the straight hole 511. The grinding fluid flows out from the straight hole 511 to the U-shaped guide channel 54 and the straight pipe 59, and then flows back into the collection tank 58 through the straight pipe 59, realizing a circulation process. At the same time, by setting the U-shaped guide channel 54, when the rotating support component 3 drives the impeller to move, the U-shaped guide channel 54 can continuously receive the dripping grinding fluid, avoiding the cleaning work of the grinding fluid dripping onto the table surface.

The driven wheel 36 drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the lower outer cover 31 and the pad 32 to rotate. When the lower outer cover 31 rotates, it slides against the inner cover 510. The pad 32 drives the impeller to rotate centrifugally through the column 33 and the key block 34, which throws out the grinding fluid inside the impeller, avoiding the presence of grinding fluid residue inside the impeller, and eliminating the need for subsequent cleaning.

[0068] This invention enables continuous processing of batch impellers, resulting in higher efficiency;

[0069] After polishing, the impeller can be centrifuged to discharge the residual grinding fluid inside the impeller. At the same time, the discharged grinding fluid can be recycled and reused, avoiding subsequent cleaning work.

[0070] Meanwhile, the present invention can also continuously receive the dripping grinding fluid through the U-shaped guide channel 54, avoiding the cleaning work of the grinding fluid dripping onto the table surface.

Preferably, the straight pipe 59 is located directly below the straight hole 511. The grinding fluid flows out from the straight hole 511 to the U-shaped guide channel 54 and the straight pipe 59, and then flows back to the collection tank 58 through the straight pipe 59 to realize the circulation process.

[0076] 4. After the impeller polishing is completed, the first cylinder 45 is started to drive the fixed plate 43 to move under the limiting action of the guide rail assembly 44. The fixed plate 43 drives the second motor 42 and the drive wheel 41 to move. The drive wheel 41 moves to contact the driven wheel 36.

1. The impeller is placed on the pad (32) and is inserted into the column (33) and key block (34); 2. The drive motor (26) drives the straight shaft (22) to rotate intermittently. The straight shaft (22) drives the synchronous belt (25) to rotate. The synchronous belt (25) drives the connecting plate (24) to rotate. The connecting plate (24) drives the sliding block (27) to move along the annular guide rail (23). The connecting plate (24) drives the rotating support assembly (3) to move at equal intervals, so that the rotating support assembly (3) moves to the bottom of the inner cover (510) in sequence. At the same time, when the rotating support assembly (3) drives the impeller to move, the U-shaped guide groove (54) can continuously receive the dripping grinding fluid and automatically guide it to the straight pipe (59). Third, start the second cylinder (51) to drive the horizontal plate (57) to move downward. The horizontal plate (57) drives the slide tube (56) to slide downward along the sleeve (53). The horizontal plate (57) drives the inner cover (510) to move downward through the connecting cover (512) and cover the lower outer cover (31). Then start the liquid pump (55) to pump the grinding fluid in the collection tank (58) through the sleeve (53), slide tube (56), connecting cover (512), and inner cover (510). 510) The impeller in the rotating support assembly (3) is polished. Then the grinding fluid flows out from the impeller and enters the straight hole (511) through the inlet (513). At this time, the U-shaped guide groove (54) is located below the straight hole (511). The grinding fluid flows out from the straight hole (511) to the U-shaped guide groove (54) and the straight pipe (59), and then flows back to the collection tank (58) through the straight pipe (59) to realize the circulation process.

4. After the impeller polishing is completed, the first cylinder (45) is started to drive the fixed plate (43) to move under the limiting action of the guide rail assembly (44). The fixed plate (43) drives the second motor (42) and the drive wheel (41) to move. The drive wheel (41) moves to contact the driven wheel (36). The second motor (42) is started to drive the drive wheel (41) to rotate. The drive wheel (41) drives the driven wheel (36) to rotate. The driven wheel (36) drives the rotating shaft (35) to rotate. The rotating shaft (35) drives the lower outer cover (31) and the pad (32) to rotate. When the lower outer cover (31) rotates, it slides against the inner cover (510). The pad (32) drives the impeller to rotate centrifugally through the column (33) and the key block (34), throwing out the grinding fluid inside the impeller.
