Description

Technical Field

[0001] The present invention relates to the technical field of water pump impeller production, and in particular to a cutting device for producing and processing water pump impellers and a processing method thereof. Background Art

[0002] As a core component of fluid machinery, the geometric accuracy of a water pump impeller directly impacts the pump's head, efficiency, and cavitation performance. Traditional impeller machining primarily involves casting a blank and then milling it using CNC machine tools. However, with the development of intelligent manufacturing equipment, the increasing prevalence of complex curved impeller designs and the demand for lightweight impellers, the use of high-strength alloy materials has placed higher demands on cutting technology.

[0003] Most existing cutting devices are based on a five-axis CNC machine tool equipped with a rotating tool, and perform layered cutting on the impeller surface through a preset program. However, this process has significant limitations: First, when the robotic arm moves along a complex three-dimensional trajectory, it is affected by the response delay of the servo system and the joint clearance, and the repeated positioning accuracy is usually difficult to meet the contour accuracy requirements of the leading edge of the new impeller blade; second, as the degree of freedom of the robotic arm increases, when the robotic arm is extended to the maximum working radius, the position drift of the end effector increases significantly, which reduces the processing accuracy. At the same time, in a closed cutting processing space, usually only one water pump impeller can be processed, and the reciprocating closing process of the cutting processing space and the repositioning process after closing significantly affect the processing efficiency of the water pump impeller.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a cutting device and a processing method for the production of water pump impellers.

[0039] Example 1: Please refer to Figures 1-11, a cutting device for the production and processing of water pump impellers, comprising a support base 1 and an outer protective frame 2, an operating cavity being formed between the support base 1 and the outer protective frame 2, impeller clamping mechanisms 3 being respectively provided on both sides of the support base 1, the two impeller clamping mechanisms 3 being able to respectively clamp and extend the impeller to be processed into the operating cavity; a translation drive mechanism 4 being provided on one side of the support base 1, the translation drive mechanism 4 being able to drive a sliding support plate 41 to translate between the two impeller clamping mechanisms 3; a cutting movable arm 5 being fixedly provided on the top of the sliding support plate 41, an angle adjustment mechanism 6 being provided on the movable end of the cutting movable arm 5, the angle adjustment mechanism 6 comprising an angle adjustment unit 61 and a cutting installation connecting plate 62, the cutting installation connecting plate 62 A cutting actuator 7 and a cutting limit mechanism 8 are respectively provided at both ends; the cutting movable arm 5 can move by driving the cutting mounting connecting plate 62 to move the cutting actuator 7 and the cutting limit mechanism 8 to the two surfaces of the blade of the impeller to be processed respectively; the angle adjustment unit 61 can rotate by driving the cutting mounting connecting plate 62 to drive the cutting actuator 7 and the cutting limit mechanism 8 to simultaneously change the angle between them and the impeller to be processed; the cutting limit mechanism 8 can fit one surface of the blade of the impeller to be processed, and the position between the cutting actuator 7 and the cutting limit mechanism 8 can be adjusted within a limited range, and the cutting actuator 7 can cut the other surface of the blade of the impeller to be processed.

[0040] When in use, the water pump impeller (the water pump impeller can be an impeller blank processed by casting, or a semi-finished impeller processed by welding, etc., which needs to be cut and trimmed) is fixed inside the impeller clamping mechanism 3 (in this embodiment, two water pump impellers can be cut at one time. Specifically, the two water pump impellers are clamped in the two impeller clamping mechanisms 3 respectively). Then, the operating cavity is closed by the outer protective frame 2, and the cutting process of the two water pump impellers can be carried out simultaneously inside the operating cavity: first, the sliding support plate 41 is driven by the translation drive mechanism 4 to carry the cutting movable arm 5 to move to the water pump impeller clamped by one impeller clamping mechanism 3, and the water pump impeller is cut. At this time, the cutting actuator 7 and the cutting limit mechanism 8 respectively provided at both ends of the cutting installation connecting plate 62 are moved to the two surfaces of the blades of the water pump impeller by the cutting limit mechanism 8. The cutting actuator 7 and the cutting limit mechanism are kept in contact with one surface of the blade of the water pump impeller. 8 can be adjusted within a limited range, and the cutting actuator 7 can cut the other surface of the blade of the impeller to be processed, so that the cutting actuator 7 can move in a small range under the limitation of the cutting limit mechanism 8, and can more accurately cut the surface of the impeller blade to remove defects on the surface of the water pump impeller to be processed (defects such as excess burrs caused by casting or welding, or positions that need to be cut and removed after the dynamic balancing test of the water pump impeller), and can effectively process the water pump impeller to eliminate the defects of the water pump impeller and improve the rotational balance of the water pump impeller. After the cutting of one water pump impeller is completed, the translation drive mechanism 4 drives the sliding support plate 41 to carry the cutting movable arm 5 to move to the water pump impeller clamped by the other impeller clamping mechanism 3 to cut the other water pump impeller, and can perform the cutting process of two water pump impellers in the process of closing the cavity in one operation, thereby improving the efficiency of batch production of water pump impellers.

[0041] Example 2: Please refer to Figures 1-11 The difference from the above embodiment is that the cutting actuator 7 includes a cutting fixed base 71, a cutting elevation adjustment unit 72, a cutting mounting base 73 and a rotary cutter 74. The cutting fixed base 71 is fixed between one end of the cutting mounting connecting plate 62; the cutting elevation adjustment unit 72 includes an elevation adjustment plate 721 and an elevation adjustment motor 722; the cutting mounting base 73 includes a cutting connecting ring plate 731, several fine-adjustment cylinders 732 and a cutting mounting base plate 733; the rotary cutter 74 includes a cutting tool holder 741 and a rotary drive motor 742.

[0042] The elevation adjustment plate 721 is fixed to the cutting connecting ring plate 731, both ends of the cutting connecting ring plate 731 are rotatably connected to the cutting fixed base 71, and the cutting knife clamp 741 is rotatably connected to the cutting mounting substrate 733; the elevation adjustment motor 722 is fixed to the cutting fixed base 71, and the elevation adjustment motor 722 is powered by the elevation adjustment gear 723 and the elevation adjustment plate 721. The elevation adjustment motor 722 can adjust the elevation angle of the cutting knife clamped inside the cutting knife clamp 741 by adjusting the elevation angle of the cutting connecting ring plate 731.

[0043] The two ends of each micro-adjustment cylinder 732 are respectively fixed between the cutting connecting ring plate 731 and the cutting mounting base plate 733. Each micro-adjustment cylinder 732 can be extended and retracted synchronously to drive the distance between the cutting knife clamped inside the cutting knife clamp 741 and the cutting mounting base 73 to adjust; the rotary drive motor 742 is power-connected to the cutting knife clamp 741, and the rotary drive motor 742 can drive the cutting knife clamped inside the cutting knife clamp 741 to rotate and cut the impeller to be processed during the movement of the cutting knife clamped inside the cutting knife clamp 741.

[0044] When in use, the cutting fixed base 71 is fixed to one end of the cutting installation connecting plate 62, and under the drive of the elevation adjustment motor 722, the elevation adjustment gear 723 and the elevation adjustment plate 721 are engaged with each other to adjust the elevation angle of the cutting connecting ring plate 731, thereby adjusting the elevation angle of the cutting knife clamped inside the cutting knife clamp 741, and adjusting the angle between the cutting knife and the blade. Since the cutting knife clamp 741 is rotatably connected to the cutting installation base plate 733, the synchronous extension and contraction of each micro-adjustment cylinder 732 can be used to adjust the elevation angle of the cutting connecting ring plate 731. The distance between the cutting knife clamped inside the entire cutting knife clamp 741 and the cutting mounting base 73 can be adjusted to adjust the distance between the cutting knife and the blade. Then, during the cutting process, the cutting knife clamped inside the cutting knife clamp 741 is driven to rotate by the rotating drive motor 742, and the angle between the cutting knife and the blade and the distance between the cutting knife and the blade are changed (and the cutting movable arm 5 can also cooperate to drive the cutting knife to move), so as to accurately and effectively cut the blade surface of the water pump impeller, thereby eliminating defects on the surface of the water pump impeller.

[0045] Example 3: Please refer to Figures 1-11The difference from the above embodiment is that the cutting limit mechanism 8 includes a limit connecting rod 81, a limit extension rod 82 and two fitting limit connecting rods 83, one end of the limit connecting rod 81 is fixed between the other end of the cutting installation connecting plate 62, and the other end of the limit connecting rod 81 is rotatably connected to the middle part of the limit extension rod 82; the two fitting limit connecting rods 83 are respectively fixed at the two ends of the limit extension rod 82, and the ends of the two fitting limit connecting rods 83 away from the limit extension rod 82 are embedded with fitting balls 84, and the fitting limit connecting rods 83 can be extended and retracted under the elastic force of the spring arranged inside, driving the fitting balls 84 to fit with the blade surface of the impeller to be processed.

[0046] The angle adjustment unit 61 includes an angle adjustment support 611 and at least two angle adjustment cylinders 612.

The fixed end of each angle adjustment cylinder 612 is fixed to the angle adjustment support 611, and the movable end of each angle adjustment cylinder 612 is fixed to the cutting installation connecting plate 62. In the process of synchronous extension and retraction of the movable end of each angle adjustment cylinder 612, the cutting installation connecting plate 62 and the angle adjustment support 611 can be driven to rotate relative to each other, and the maximum angle of relative rotation between the cutting installation connecting plate 62 and the angle adjustment support 611 can be limited through the movable stroke of each angle adjustment cylinder 612.

[0047] During specific use, the two fitting limit links 83 are extended and retracted under the elastic force of the springs inside, driving the fitting ball 84 to fit the blade surface of the impeller to be processed, and the other end of the limiting connecting rod 81 is rotatably connected to the middle part of the limiting extension rod 82, so as to ensure that the distance between the limiting connecting rod 81 (the middle part of the limiting extension rod 82) and the blade surface of the water pump impeller is kept at a relatively constant distance (varies within the range of millimeters), and through the action of the two fitting limit links 83, the influence of the curvature change of a single contact position on the position of the limiting connecting rod 81 is reduced, so that the distance between the limiting connecting rod 81 and the cutting actuator 7 is kept relatively constant (through the fitting limit link 8 3 is telescopically adapted to the change in the thickness of the water pump impeller along the direction of the line connecting the limiting connecting rod 81 and the cutting actuator 7 due to the change in the thickness and curvature of the water pump impeller), and in specific use, the movable ends of the various angle adjustment cylinders 612 are synchronously extended and retracted to drive the cutting installation connecting plate 62 and the angle adjustment support 611 to generate relative rotation, and the movable stroke of the various angle adjustment cylinders 612 can be used to limit the maximum angle of relative rotation between the cutting installation connecting plate 62 and the angle adjustment support 611, thereby adapting to the curvature of the water pump impeller and effectively cutting the blade surface of the water pump impeller to eliminate defects within the smaller cutting range of the cutting actuator 7.

[0048] Example 4: Please refer to Figures 1-11 The difference from the above embodiment is that the impeller clamping mechanism 3 includes a clamping connecting shaft seat 31, a clamping angle adjustment shaft 32 is rotatably installed inside the clamping connecting shaft seat 31, and a three-jaw chuck 33 is fixedly provided on the end of the clamping angle adjustment shaft 32 close to the operating cavity, and the end of the clamping angle adjustment shaft 32 away from the operating cavity is powered by a clamping angle adjustment motor 34; the three-jaw chuck 33 can clamp the impeller to be processed, and the clamping angle adjustment motor 34 can adjust the angle of the impeller to be processed clamped by the three-jaw chuck 33 by driving the clamping angle adjustment shaft 32 to rotate.

The translation motor 421 can drive the translation drive screw 422 to rotate, thereby driving the sliding support plate 41 to translate between the two impeller clamping mechanisms 3.

[0050] The outer protective frame 2 is arranged outside the support base 1, and the outer protective frame 2 includes a fixed frame 21 and a movable door panel 22.

The various free dimensions of the cutting movable arm 5 cooperate together to drive the movable end of the cutting movable arm 5 to move inside the operating cavity.

[0051] When in use, the movable door panel 22 is slidably connected to the fixed frame 21, and the opening and closing of the movable door panel 22 can open and isolate the operating cavity, and can effectively isolate the cutting process inside the operating cavity. During the cutting process, the water pump impeller is stably clamped by the three-jaw chuck 33 (the three-jaw chuck 33 is a common technical solution in the prior art and will not be described here). The clamping angle adjustment motor 34 outputs power, and the clamping angle adjustment shaft 32 is driven to rotate and drive the three-jaw chuck 33 to carry the water pump impeller to rotate, thereby adjusting the angle of the impeller to be processed clamped by the three-jaw chuck 33 to cooperate with the cutting process of the water pump impeller; the translation motor 421 outputs power Drive the translation drive screw 422 to rotate, and through the threaded engagement between the extension connecting plate 411 and the corresponding translation drive screw 422, drive the extension connecting plate 411 to move, and then drive the sliding support plate 41 to translate between the two impeller clamping mechanisms 3 under the restriction of the translation track 11, and then drive the cutting movable arm 5 to drive the cutting actuator 7 and the cutting limit mechanism 8 to move, and through the free dimension of the cutting movable arm 5, the movable end of the cutting movable arm 5 can be driven to move inside the operating cavity, so that the cutting actuator 7 can be driven to move to any required cutting position of the water pump impeller, so as to cooperate with the cutting actuator 7 and the cutting limit mechanism 8 to eliminate the defects of the cutting process.
