Description

Technical Field

[0001] The invention relates to the technical field of screw pumps, and in particular to multi-cyclone rotor forming equipment and a rotor made thereof. Background Art

[0002] According to different application scenarios, the rotor of the screw pump can be divided into a hollow rotor and a solid rotor, wherein the hollow rotor can be processed by a roll forming device, while the solid rotor is generally cut by a whirlwind milling device. For the processing of the solid rotor, the staff first needs to clamp the rotor blank in the chuck of the whirlwind milling device, and the other end of the rotor blank is positioned by a pin. The subsequent processing steps can refer to sections

[0013] to

[0019] in the "A processing device for a metal rotor of a screw oil pump" with publication number CN208099352U. Since the solid rotor has a large amount of cutting, it needs to be processed multiple times, but each whirlwind milling process takes a lot of time, resulting in the production cycle of the solid rotor being too long and the manufacturing cost being extremely high. Summary of the invention

[0003] The invention aims to provide a multi-cyclone rotor forming device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The multi-cyclone rotor forming device according to the first embodiment of the present invention comprises:

[0005] A machine tool, wherein a headstock and a tailstock are sequentially mounted along the front-rear direction, the headstock is provided with a rotatable chuck, and the tailstock is provided with an ejector pin;

[0006] There are two or more cyclone cutting assemblies, and the cyclone cutting assembly includes a slide, a front-to-back moving mechanism, a cyclone milling device and a left-right moving mechanism. The slide is slidably connected to the machine tool along the front-to-back direction, and any two adjacent slides are arranged in a front-to-back interval. The relative position between the slide and the machine tool is limited by the front-to-back moving mechanism. The cyclone milling device is slidably connected to the slide along the left-to-right direction, and the relative position between the cyclone milling device and the slide is limited by the left-to-right moving mechanism. At least one of the cyclone milling devices is rotationally driven to have multiple radially outward external cyclone milling cutters, and at least one of the cyclone milling devices is rotationally driven to have multiple radially inward internal cyclone milling cutters.

[0007] The multi-cyclone rotor forming equipment according to the embodiment of the invention has at least the following beneficial effects: the machine head clamps the rotor blank through the chuck and provides it with rotational power, and the other end of the rotor blank is supported by the ejector pin. Since the cutting amount of the rotor blank during rough machining is large, multiple external cyclone milling cutters can be used to perform single-point cutting on one side of the rotor blank, and since the cutting amount of the rotor blank during fine machining is small, multiple internal cyclone milling cutters can be used to perform multi-point cutting on the circumferential surface of the rotor blank. Whenever the rotor blank rotates one circle, the cyclone milling device advances at a uniform speed by a pitch distance within the time it takes for the rotor blank to rotate one circle. During this process, the cyclone milling device used for rough machining needs to dynamically adjust its left and right positions according to the machining progress of the rotor blank, while the cyclone milling device used for fine machining only needs to statically adjust its left and right positions according to the eccentricity of the rotor. Compared with the prior art, the invention can perform rough and fine machining on the rotor blank at the same time, so as to greatly improve the machining efficiency of the solid rotor, thereby reducing the machining cost of the solid rotor.

[0008] According to some embodiments created by the present invention, all the cyclone milling devices are provided with a rotation axis arranged along the front-to-back direction, the cutting points of the multiple external cyclone milling cutters are located on the same circumference with the corresponding rotation axis as the center axis, and the cutting points of the multiple internal cyclone milling cutters are located on the same circumference with the corresponding rotation axis as the center axis, so as to ensure the processing accuracy of each of the cyclone milling devices.

[0009] According to some embodiments of the present invention, in order to achieve a sliding connection between the slide and the machine tool, the machine tool is provided with a first slide rail arranged along a front-to-rear direction, and all the slides are slidably connected to the first slide rail.

[0010] According to some embodiments of the present invention, in order to achieve the sliding connection between the whirlwind milling device and the slide seat, all slide seats are provided with a second slide rail arranged along the left and right direction, and each of the whirlwind milling devices is slidably connected to the corresponding second slide rail.

[0011] According to some embodiments of the present invention, for the convenience of description, the cyclone cutting assembly with the external cyclone milling cutter may be referred to as a rough machining cyclone cutting assembly, and the cyclone cutting assembly with the internal cyclone milling cutter may be referred to as a finishing cyclone cutting assembly. Since the rough machining and semi-finishing of the rotor blank require a larger amount of cutting, the number of the rough machining cyclone cutting assemblies is two or more, and since the finishing of the rotor blank requires a relatively smaller amount of cutting, the number of the finishing cyclone cutting assemblies is no more than the number of the rough machining cyclone cutting assemblies.

[0012] According to some embodiments of the present invention, in order to follow the principle of rough machining before fine machining, the direction from the fine machining whirlwind cutting assembly to the rough machining whirlwind cutting assembly is the machining direction of the rotor blank, so that any part of the rotor blank can transition from rough machining to fine machining.

[0013] According to some embodiments of the present invention, in order to implement the internal whirlwind milling process during finishing, the whirlwind milling device of the finishing whirlwind cutting assembly is provided with a through hole for the rotor blank to pass through, and all cutting points of the internal whirlwind milling cutter are located in the through hole.

[0014] According to some embodiments of the present invention, since the whirlwind milling device used for rough machining needs to dynamically adjust its left and right position during the machining process, the left and right moving mechanism of the rough machining whirlwind cutting assembly is electrically controlled, and since the whirlwind milling device used for fine machining does not need to dynamically adjust its left and right position during the machining process, the left and right moving mechanism of the fine machining whirlwind cutting assembly can be electrically controlled or manually controlled.

[0015] According to some embodiments created by the present invention, since the screw slider moving mechanism, the gear rack moving mechanism, the cylinder and the linear motor can all realize linear movement, the front and back moving mechanism and the left and right moving mechanism include a screw slider moving mechanism, a gear rack moving mechanism, a cylinder or a linear motor.

[0016] The rotor according to the second embodiment of the present invention is formed by the multi-cyclone rotor forming equipment described above.

[0017] The rotor according to the embodiment of the invention has at least the following beneficial effects: compared with the existing solid rotor, the rotor processed by the multi-cyclone rotor forming equipment has more advantages in production efficiency and production cost.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description and in part will become apparent from the following description or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0029] like Figures 1 to 3As shown, according to the multi-cyclone rotor forming equipment of the first embodiment created by the present invention, it includes a machine tool 100 and at least two cyclone cutting assemblies, the length of the machine tool 100 is greater than the length of the rotor blank 200, and the front and rear sides of the machine tool 100 are respectively provided with a head 110 and a tailstock 120, the head 110 is equipped with a controller (not shown in the drawings) and a first rotation drive device (not shown in the drawings), the first rotation drive device can be optionally a servo motor, the first rotation drive device rotationally drives a chuck 111 for clamping the rotor blank 200, the chuck 111 can be optionally a three-jaw chuck, the tailstock 120 is provided with a pin 121, the pin 121 is opposite to the chuck 111, and the rotor blank 200 is provided with a positioning hole on its rotation axis for supporting the pin 121, so that the first rotation drive device can drive the rotor blank 200 to rotate.

[0030] Furthermore, in order to adapt to rotor blanks 200 of different lengths, the machine tool 100 is provided with a first slide rail 130 along the front-to-back direction, and the tail stock 120 is slidably connected to the first slide rail 130 and can be temporarily fixed to the machine tool 100 by a positioning pin (not shown in the drawings), so that the length between the machine head 110 and the tail stock 120 can be adaptively adjusted according to the length of the rotor blank 200.

[0031] In addition, each of the whirlwind cutting assemblies includes a slide 310, a whirlwind milling device 320, a front-to-back moving mechanism (not shown in the drawings) and a left-to-right moving mechanism 330. The slide 310 is slidably connected to the first slide rail 130 of the machine tool 100. Any two adjacent slides 310 are arranged in a front-to-back interval. The front-to-back moving mechanism is used to limit the relative position between the slide 310 and the machine tool 100, so as to adjust the front-to-back position of the slide 310. At the same time, the slide 310 is provided with a second slide rail 311 in the left-to-right direction. The whirlwind milling device 320 is slidably connected to the second slide rail 311. The left-to-right moving mechanism 330 is used to limit the relative position between the whirlwind milling device 320 and the slide 310, so as to adjust the left-to-right position of the whirlwind milling device 320. The front-to-back moving mechanism and the left-to-right moving mechanism 330 include but are not limited to a cylinder, a linear motor, a screw slider moving mechanism or a gear rack moving mechanism. In this embodiment, the front-to-back moving mechanism and the left-to-right moving mechanism 330 can be selected as a screw slider moving mechanism. It should be noted that the forward and backward movement and the left and right movement of each of the whirlwind milling devices 320 are independently controlled and do not interfere with each other.

[0032] Specifically, the whirlwind milling device 320 includes a second rotation driving device (not shown in the drawings), a rotating frame 321 and a support frame 322. The rotating frame 321 is rotatably connected to the support frame 322 through a bearing (not shown in the drawings). The support frame 322 is slidably connected to the second slide rail 311 of the slide seat 310. The second rotation driving device can be optionally a motor, which is used to rotationally drive the rotating frame 321. At this time, the rotation axis of the rotating frame 321 is arranged along the front-to-back direction, and it is horizontally aligned with the rotation axis of the rotor blank 200. The rotating frame 321 is hollow and has a through hole 323 for the rotor blank 200 to pass through. The rotating frame 321 has a plurality of mounting grooves evenly distributed in the circumference. External cyclone milling cutters 324 facing radially outward are installed in all mounting grooves of at least one rotating frame 321. At this time, the cutting points of all external cyclone milling cutters 324 are located outside the through hole 323. Internal cyclone milling cutters 325 facing radially inward are installed in all mounting grooves of at least one rotating frame 321. At this time, the cutting points of all internal cyclone milling cutters 325 are located inside the through hole 323.

[0033] For the convenience of description, the whirlwind cutting assembly with the outer whirlwind milling cutter 324 may be referred to as a roughing whirlwind cutting assembly 301, and the whirlwind cutting assembly with the inner whirlwind milling cutter 325 may be referred to as a finishing whirlwind cutting assembly 302. Figure 4 As shown, since the rough machining and semi-finishing of the rotor blank 200 require a large amount of cutting, the rough machining cyclone cutting assembly 301 can perform single-point cutting on the rotor blank 200 by using multiple external cyclone milling cutters 324. At this time, the rough machining cyclone cutting assembly 301 is located on the left or right side of the rotor blank 200 to disperse the cutting amount to the multiple external cyclone milling cutters 324, thereby extending the service life of each of the external cyclone milling cutters 324 and accelerating the cutting efficiency of the rotor blank 200. Since the finishing of the rotor blank 200 requires a smaller amount of cutting, the finishing cyclone cutting assembly 302 can perform multi-point cutting on the rotor blank 200 by using multiple internal cyclone milling cutters 325. At this time, the finishing cyclone cutting assembly 302 is sleeved outside the rotor blank 200 to increase the cutting frequency of the rotor blank 200, thereby effectively reducing the surface roughness of the rotor blank 200.

[0034] In the invention, the number of the roughing cyclone cutting assemblies 301 is two, which correspond to the roughing process and the semi-finishing process respectively, and the number of the finishing cyclone cutting assembly 302 is one, which corresponds to the finishing process. However, in other embodiments, the number of the roughing cyclone cutting assemblies 301 can also be one, three, four, etc., and the number of the finishing cyclone cutting assemblies 302 can also be one or more. The invention does not limit the number of the two, but in general, the number of the finishing cyclone cutting assemblies 302 is not more than the number of the roughing cyclone cutting assemblies 301.

[0035] In order to follow the principle of roughing first and then finishing, if the rotor blank 200 is processed from back to front, all finishing cyclone cutting assemblies 302 are located behind all roughing cyclone cutting assemblies 301, so that the rotor blank 200 can be rough-machined by the roughing cyclone cutting assembly 301 first, and then finished by the finishing cyclone cutting assembly 302. In addition, the machine tool 100 needs to reserve enough clearance for the cyclone cutting assemblies, so that when the first roughing cyclone cutting assembly 301 processes the rotor blank 200 or when the last finishing cyclone cutting assembly 302 processes the rotor blank 200, the positions of the remaining cyclone cutting assemblies can be reasonably planned to avoid interference with each other.

[0036] For a single screw pump, the more leads it has, the higher its output pressure will be, and the number of leads is equal to the total spiral length of the rotor / the pitch of the rotor, so each rotor has at least one lead, and there is a fixed eccentricity e between the center line of the rotor and its axis of rotation, which enables the rotor to perform planetary motion in the stator. According to the rotor whirlwind milling process, each time the rotor blank 200 rotates one circle under the drive of the first rotary drive device, the whirlwind cutting assembly needs to advance a pitch distance at a uniform speed within the time when the rotor blank 200 rotates one circle, so as to process a pitch that meets the technical requirements. Since the finishing time of the rotor blank 200 is consistent with its rough machining time, the present invention creates a method of increasing the cutting frequency by using multiple internal whirlwind milling cutters 325 to perform multi-point cutting on the rotor blank 200, thereby significantly reducing the surface roughness of the rotor blank 200 within a limited time.

[0037] It should be noted that, since the whirlwind milling process of the rotor requires a large amount of cutting, the rotation speed of the rotor blank 200 is very slow, generally not higher than 1 / 30rpm. Taking the rotation speed of 1 / 30rpm as an example, it takes 30 minutes for the rotor to rotate once. During this period, the whirlwind cutting assembly moves forward at a uniform speed along the machining direction of the rotor by a distance of one pitch. In order to accurately control the front-to-back displacement of the whirlwind cutting assembly, the front-to-back moving mechanism of the whirlwind cutting assembly is preferably driven by a servo motor.

[0038] like Figure 4 As shown, since the outer cyclone milling cutter 324 of the rough machining cyclone cutting assembly 301 cuts along one side of the rotor blank 200, and the rough machining cyclone cutting assembly 301 advances at a uniform speed as the rotor blank 200 rotates, the distance between the rotation axis of the rotating frame 321 and the center line of the rotor blank 200 will change orthogonally with the machining progress of the rotor blank 200. In order to ensure that the chip point of the outer cyclone milling cutter 324 can always be located on the eccentric arc of the rotor, the cyclone milling device 320 of the rough machining cyclone cutting assembly 301 needs to dynamically adjust its left and right positions according to the machining progress of the rotor blank 200. The displacement of the movement takes the pitch and eccentricity of the rotor as parameters, and cycles with the time for the rotor blank 200 to rotate one circle. The operator can input preset pitch and eccentricity to allow the controller to perform parameterized control. In order to accurately control the left-right displacement of the whirlwind milling device 320 of the rough machining whirlwind cutting assembly 301, the left-right moving mechanism 330 of the rough machining whirlwind cutting assembly 301 is preferably driven by a servo motor.

[0039] In addition, since the inner cyclone cutter 325 of the finishing cyclone cutting assembly 302 cuts along the circumference of the rotor blank 200, and the finishing cyclone cutting assembly 302 moves forward at a uniform speed as the rotor blank 200 rotates, when the distance between the rotation axis of its rotating frame 321 and the rotation axis of the rotor blank 200 is equal to the eccentricity of the rotor, the chip point of the inner cyclone cutter 325 is always located on the eccentric arc of the rotor. It can be understood that once the cyclone milling device 320 of the finishing cyclone cutting assembly 302 adjusts its left and right positions according to the eccentricity of the rotor, its left and right positions do not need to be adjusted again during the processing of the rotor blank 200. To this end, the left and right moving mechanism 330 of the finishing cyclone cutting assembly 302 can be manually controlled or electrically driven. In this embodiment, it is manually controlled by a rotating handle 331 with a scale to save manufacturing costs.

[0040] In some embodiments of the present invention, in order to ensure the processing accuracy of each of the cyclone milling devices 320, the cutting points of the multiple external cyclone milling cutters 324 are all located on the same circumference with the rotation axis of the corresponding rotating frame 321 as the center axis, and the cutting points of the multiple internal cyclone milling cutters 325 are all located on the same circumference with the rotation axis of the corresponding rotating frame 321 as the center axis, that is, in the same rough machining cyclone cutting assembly 301, the cutting amount of all external cyclone milling cutters 324 is consistent, and in the same fine machining cyclone cutting assembly 302, the cutting amount of all internal cyclone milling cutters 325 is consistent.

[0041] The rotor according to the second embodiment of the present invention is processed by the multi-cyclone rotor forming equipment according to the first embodiment of the present invention. Compared with the existing solid rotor, the rotor has more advantages in production efficiency and production cost.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
