One type of impeller is plate-shaped with deep helical grooves on its surface, which enables it to function as an impeller during high-speed rotation. For the manufacturing of this type of impeller, the helical grooves are usually machined into the surface. Therefore, a cutting device for machining helical centrifugal pump impellers needs to be designed.

Multiple sliding grooves are evenly and horizontally opened on the sliding plate. A sliding table is horizontally slidably installed in each of the multiple sliding grooves. A pressure strip is vertically fixed on the top surface of the sliding table, and a roller is fixed on the bottom surface of the sliding table. A first electric telescopic rod is vertically fixed on the bracket, and a conical column is vertically fixed at the top of the first electric telescopic rod. The adjusting component is... While the existing technology overcomes the problem that the impeller cover plate is clamped and secured by the abutment plate and the receiving plate, causing the upper and lower end faces of the impeller cover plate to need to contact the abutment plate and the receiving plate, and the upper end face of the impeller cover plate is blocked, affecting the processing of the spiral groove on the end face of the impeller cover plate, and the abutment plate and the receiving plate need to be separated during later adjustment, making the initial adjustment inconvenient, the chips cut by the milling cutter in the existing technology fall directly onto the worktable or the ground, requiring manual cleaning by the operator later, which increases the inconvenience of the cutting device in later use.

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a cutting device for machining a spiral centrifugal pump impeller includes an installation chamber 1. Support legs are installed at the bottom of both sides of the installation chamber 1, and both sets of support legs have anti-slip plates at their bottoms to facilitate subsequent support of the installation chamber 1 and its components. A sealing cover is hinged to one end of the front of the installation chamber 1, and a handle and a buckle are provided on one side of the front end of the sealing cover. A cutting assembly 2 is installed at the center of the top of the installation chamber 1. The cutting assembly 2 includes an installation through groove 201 located at the center of the top of the installation chamber 1. The installation through groove 201 communicates with the inside and outside of the installation chamber 1, facilitating the movement of the fixed slider 200 and electrical... The installation and connection of the electric push rod 202 is convenient, and it also facilitates the entry of external air later. Both ends of the mounting groove 201 are provided with guide grooves, and one side of each guide groove is slidably equipped with a mounting slider connected to the fixed slider 200. An electric push rod 202 is installed inside one guide groove. A fixed slider 200 extending to the outside is slidably provided on one side of the mounting groove 201. An electric push rod 202 is installed on one end of the back side of the fixed slider 200, and the electric push rod 202 is connected to the side of the mounting groove 201 away from the fixed slider 200. The electric push rod 202 connects to... The connection design of the fixed slider 200, combined with the mounting slot 201, facilitates the later left and right movement of the fixed slider 200 and its components via the electric push rod 202. A guide rail 207 extending into the mounting chamber 1 is mounted on the bottom of the fixed slider 200. A connecting slider 203 extending outwards is slidably mounted on one front end of the bottom of the guide rail 207. An electric push rod 208 is mounted on the back end of the guide rail 207, and its output end is connected to the connecting slider 203. The electric push rod 208 drives the connecting slider 203 to move back and forth within the guide rail 207. The device can move and then drive the servo motor 206 and the milling cutter 205 to change their positions arbitrarily in the front, back, left, and right directions, facilitating subsequent cutting operations. An electric push rod 204 is installed at the bottom of the connecting slider 203. The servo motor 206 is installed at the bottom output end of the electric push rod 204, and the milling cutter 205 is installed at the bottom output end of the servo motor 206. The electric push rod 204 can realize the lifting and lowering of the placement plate 306 and the milling cutter 205, which facilitates the contact between the milling cutter 205 and the impeller. Then, in conjunction with the rotation of the servo motor 206 and the milling cutter 205, the milling cutter 205 can easily perform rotational cutting operations in the later stage.

[0025] like Figure 2 , Figure 4 , Figure 6As shown, a partition 4 is installed in the middle of the installation chamber 1. The partition 4 facilitates the installation of the fixing component 3 and above. The partition 4 has openings 6 at both ends and sides that connect to its interior and exterior. These openings 6 allow for the collection of debris carried by external wind. The fixing component 3 is installed in the middle of the top of the opening 6. The fixing component 3 includes a servo motor 300 installed in the middle of the top of the partition 4. The servo motor 300 facilitates the rotation of the impeller installed later, improving the accuracy and convenience of subsequent cutting. A turntable 301 is installed at the output end of the servo motor 300. An annular guide groove is provided on the outer side of the turntable 301, and connecting rods extending to the outside are slidably provided on both sides inside the annular guide groove. The sides of the two sets of connecting rods that are far apart are fixedly connected to the two sides inside the mounting chamber 1. The turntable 301 allows for the installation of the placement plate 306 and above. Then, in conjunction with the annular guide groove and connecting rods, the turntable 301 and above can be supported and limited. The placement plate 306 is installed at the middle position of the top of the turntable 301. A placement groove is provided at the location to facilitate the placement of the impeller's central shaft later. Limiting grooves are provided at the middle positions of both sides of the placement plate 306, and guide rods that connect to the connecting plate 304 are inserted into the opposite sides of both sets of limiting grooves. This design of the limiting grooves and guide rods facilitates the movement and expansion of the connecting plate 304, and also conveniently limits its movement to prevent it from rotating with the fixing screw 303. Internally threaded fixing plates 302 are installed on both sides of the bottom of the placement plate 306. Both sets of internally threaded fixing plates 302 are threaded inside. The device is equipped with a fixing screw 303 extending to its exterior. Through the threaded engagement design of the internal threaded fixing plate 302 and the connecting plate 304, the fixing screw 303 can be rotated and moved to fix the moving connecting plate 304. The connecting plate 304 is rotatably sleeved on the outer side of the two sets of fixing screws 303 that are far apart. The top of the two sets of connecting plates 304 that are close to each other is equipped with an arc-shaped clamping block 305. The two sets of arc-shaped clamping blocks 305 cooperate with each other. Through the design of the arc-shaped clamping block 305 and its cooperation with the connecting plate 304, the fixing and clamping work of the impeller can be conveniently carried out in the later placement.

[0026] like Figure 2 , Figure 7 , Figure 8As shown, a collection component 5 extending to the outside is installed at the inner bottom of the installation chamber 1. The collection component 5 includes a collection groove 500 slidably connected to the inner bottom of the installation chamber 1. The collection groove 500 is positioned directly below the partition 4 and engages with the opening 6. Installation grooves are provided on both sides of the bottom of the collection groove 500, and installation sliders connected to the inner sides of the installation chamber 1 are slidably installed inside the installation grooves, facilitating the later sliding connection of the collection groove 500. A frustum-shaped filter screen 502 is installed at the middle position of the bottom of the collection groove 500. The frustum-shaped filter screen 502 facilitates the filtration of debris, and its frustum shape also... This prevents clogging, allowing debris to roll down its truncated cone-shaped inclined surface into the bottom of the collection tank 500 for collection. The collection assembly 5 also includes a fan 501 installed at the middle of the bottom of the installation chamber 1, with the bottom of the fan 501 extending to the outside of the installation chamber 1 and cooperating with the truncated cone-shaped filter plate 502. The operation of the fan 501 can drive outside air into the interior of the installation chamber 1 through the installation channel 201, and then carry debris into the collection tank 500 through the opening 6 for collection. The debris is then filtered by the truncated cone-shaped filter plate 502, and excess air can be discharged to the outside of the installation chamber 1 through the fan 501.

[0027] It should be noted that, when using this cutting device for processing spiral centrifugal pump impellers, the operator can first move the device to the designated location and connect the power supply. Then, the centrifugal pump impeller to be processed is placed on the top of the placement plate 306. By rotating the fixing screw 303, the connecting plate 304 and the arc-shaped clamping block 305 are driven. Finally, the centrifugal pump impeller can be clamped and fixed by the arc-shaped clamping block 305, which is convenient for subsequent cutting work. At the same time, the cutting position of the impeller can be changed by the servo motor 300 during cutting.

[0028] During cutting, the left and right positions of the milling cutter 205 can be easily adjusted by the electric push rod 202, the mounting slot 201 and the fixed slider 200. Then, the front and back positions of the milling cutter 205 can be adjusted by the electric push rod 208, the guide rail 207 and the connecting slider 203. Finally, the up and down positions of the milling cutter 205 can be adjusted by the electric push rod 204. At this time, the servo motor 206 drives the milling cutter 205 to rotate, which can complete the work of external grooving or trimming of the impeller.

[0029] The debris generated during trimming can be drawn into the installation chamber 1 by the operation of the fan 501, which draws outside air through the installation channel 201. The air then carries the debris through the opening 6 into the collection tank 500 for collection. The debris is then filtered by the frustum-shaped filter screen 502. Excess airflow can be discharged to the outside of the installation chamber 1 by the fan 501. This completes the automatic cleaning of debris, effectively preventing debris from falling directly onto the workbench or the ground, and ensuring the cleanliness of the device in later use.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
