Description

Technical Field

[0001] This utility model belongs to the technical field of testing equipment for rotor spinning machines, and particularly relates to an automatic sway meter for rotor spinning machines. Background Technology

[0002] Rotor spinning machines are key pieces of equipment in the modern spinning industry, and the geometric accuracy of their core component, the rotor (especially its runout and vibration), directly affects yarn quality. When the rotor rotates at high speeds (typically tens of thousands of revolutions per minute), radial eccentricity or end-face tilting can lead to uneven yarn thickness, increased breakage rates, and even accelerated equipment wear. Therefore, high-precision detection of rotor runout and vibration is a crucial aspect of rotor spinning machine manufacturing.

[0003] Traditional testing equipment often employs single-direction clamping or simple positioning methods, such as relying solely on bottom support or top single-point clamping. During rotation, the rotor is prone to displacement due to positioning reference deviations, resulting in insufficient axial stability. The dial indicator cannot accurately capture the actual runout and fluctuation, especially at high speeds, where the error is significantly amplified, leading to distorted measurement data. Furthermore, traditional testing equipment has low automation: loading and unloading operations rely on manual placement, resulting in low efficiency and poor positioning consistency; manual adjustment of the dial indicator position is required during measurement, making rapid and accurate automatic testing difficult.

[0004] Therefore, there is an urgent need for a device that can automatically load and unload rotors, perform high-precision positioning and clamping, and automatically measure runout and bounce during rotation, in order to solve the problems of unstable positioning, low efficiency and poor accuracy of traditional detection equipment. To this end, an automatic runout meter for rotor spinning machines is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an automatic sway meter for rotor spinning machines.

[0006] To achieve the above objectives, this utility model provides an automatic yaw meter for rotor spinning machines, comprising:

[0007] The box has a working platform on the front side, and a turntable is rotatably connected to the working platform. The turntable has at least four workstations evenly arranged circumferentially.

[0008] Each workstation is fixedly connected to a positioning post, and a spindle is slidably connected through the workstation corresponding to the axial center position of the positioning post.

[0009] A rotating cup is placed on the workstation. One end of the rotating cup has a large-diameter opening, and the other end has a small-diameter opening. The outer diameter of the positioning post is clearance-fitted with the inner diameter of the large-diameter opening, and the mandrel is interference-fitted with the small-diameter opening.

[0010] Several of the aforementioned workstations are respectively equipped with loading / unloading components, clamping components, detection components, and separation components in clockwise / counterclockwise order, which are used for loading / unloading the rotor, clamping the rotor and the mandrel together, detecting the rotor's sway, and separating the rotor from the mandrel.

[0011] Preferably, the loading and unloading assembly is a robotic arm.

[0012] Preferably, the clamping assembly includes a clamping bracket, a fixing column, and a clamping telescopic cylinder. The clamping bracket is C-shaped, the fixing column is fixed to the top of the clamping bracket and located above the working platform, and the clamping telescopic cylinder is fixed to the bottom of the clamping bracket and located below the working platform. The bottom of the fixing column has an insertion hole corresponding to the mandrel, and the top of the clamping telescopic cylinder has an ejection column corresponding to the mandrel. When the clamping telescopic cylinder extends, the ejection column can insert the top of the mandrel into the insertion hole.

[0013] Preferably, the detection assembly includes a detection bracket, a rotating column, and a detection telescopic cylinder; the rotating column is fixed to the top of the detection bracket and located above the working platform; the detection telescopic cylinder is fixed to the bottom of the detection bracket and located below the working platform; after the detection telescopic cylinder extends, it can lift the mandrel and make it abut against the bottom of the rotating column, and the rotating column is used to drive the mandrel abutting against it to rotate; a dial indicator is fixed on the detection bracket corresponding to the rotating cup.

[0014] Preferably, both the output end of the rotating column and the output end of the detection telescopic cylinder are fixedly connected to a pin, and limit holes are opened on the upper and lower bottom surfaces of the mandrel, with the pin matching the limit holes.

[0015] Preferably, the separation assembly includes a separation bracket, and a separation telescopic cylinder is fixedly connected to the top of the separation bracket. The movable end of the separation telescopic cylinder corresponds to the top of the mandrel, and when the separation telescopic cylinder expands, it can push the mandrel away from the rotating cup and slide downward.

[0016] Preferably, the top of the mandrel is tapered.

[0017] Preferably, the turntable is driven by a rotating motor, and the turntable is spaced apart from the working platform, such that when the mandrel is separated from the rotating cup, the bottom of the mandrel abuts against the top surface of the working platform, and when the mandrel is engaged with the rotating cup, the bottom of the mandrel is higher than the top surface of the working platform.

[0018] Compared with the prior art, the present invention has the following advantages and technical effects:

[0019] This application presents a multi-station automated production line design, employing a rotary table with at least four circumferentially distributed stations, including loading / unloading, clamping, inspection, and separation components, forming a closed-loop automated inspection process. This replaces the traditional single-station manual operation mode, achieving fully mechanized and continuous operation of rotor inspection. The rotary table rotation causes the stations to flow sequentially, with each component having a clearly defined function: the loading / unloading component automatically loads / unloads parts, the clamping component secures the rotor, the inspection component measures runout, and the separation component separates the rotor from the mandrel, avoiding positioning deviations and efficiency losses caused by manual intervention. The functional components are arranged in a station sequence, forming a standardized inspection process. The design of the positioning column and mandrel combines structural rigidity with adaptability and flexibility, allowing for compatibility with different rotor specifications through component replacement. The modular architecture facilitates equipment maintenance and functional expansion. Combined with the standardized station operation process, this significantly improves the stability, compatibility, and data traceability of the inspection process, fundamentally solving the technical bottlenecks of unstable positioning, low efficiency, and poor accuracy in traditional equipment, and meeting the modern spinning industry's demand for high-precision automated rotor inspection.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 7 As shown, this embodiment provides an automatic sway meter for a rotor spinning machine, comprising:

[0032] The box 1 has a work platform 2 on the front side of the box 1. A turntable 3 is rotatably connected to the work platform 2. At least four workstations are evenly arranged on the turntable 3 in the circumferential direction.

[0033] Each workstation is fixedly connected to a positioning post 4, and a spindle 5 is slidably connected through the corresponding axial position of the positioning post 4 at each workstation.

[0034] A rotating cup 6 is placed on the workstation. One end of the rotating cup 6 has a large diameter opening and the other end has a small diameter opening. The outer diameter of the positioning post 4 is clearance-fitted with the inner diameter of the large diameter opening, and the spindle 5 is interference-fitted with the small diameter opening.

[0035] Several workstations are respectively equipped with loading and unloading components, clamping components 7, detection components 8 and separation components 9 in clockwise / counterclockwise order, which are used for loading and unloading the rotating cup 6, clamping the rotating cup 6 and the mandrel 5 together, detecting the sway of the rotating cup 6 and separating the rotating cup 6 and the mandrel 5.

[0036] This application presents a multi-station automated production line design, employing a rotary table 3 with at least four circumferentially evenly distributed stations containing loading / unloading, clamping, inspection, and separation components 9, forming a closed-loop automated inspection process. This replaces the traditional single-station manual operation mode, achieving fully mechanized and continuous operation of the rotating cup 6 inspection process. The rotation of the rotary table 3 causes the stations to flow sequentially, with each component having a clearly defined function: the loading / unloading component is responsible for automatic loading / unloading, the clamping component 7 fixes the rotating cup 6, the inspection component 8 performs runout measurement, and the separation component 9 separates the rotating cup 6 from the mandrel 5, avoiding positioning deviations and efficiency losses caused by manual intervention. The functional components are arranged in the order of the workstations to form a standardized testing process. The design of the positioning column 4 and the mandrel 5 combines structural rigidity with adaptability and flexibility. Different specifications of rotors 6 can be compatible by replacing parts. The modular architecture facilitates equipment maintenance and functional expansion. Combined with the standardized workstation operation process, it significantly improves the stability, compatibility and data traceability of the testing process. It fundamentally solves the technical bottlenecks of unstable positioning, low efficiency and poor accuracy of traditional equipment, and meets the needs of modern spinning industry for high-precision automated testing of rotors 6.

[0037] The design was further optimized by incorporating a robotic arm for loading and unloading.

[0038] As a loading and unloading component, the robotic arm replaces traditional manual operation with a programmable robotic arm structure, enabling precise gripping and placement of the rotating cup 6. This eliminates the inconsistency issues caused by uneven force and positional deviations during manual placement, ensuring that the installation position of each rotating cup 6 at the workstation strictly meets the inspection benchmark requirements. Its high-speed response characteristics, synchronized with the periodic rotation of the turntable 3 workstation, achieve seamless connection between "loading—inspection—unloading," significantly improving inspection efficiency and meeting the high-speed requirements of industrial batch inspection. The end effector of the robotic arm can be modularly replaced according to the external dimensions of the rotating cup 6, ensuring compatibility. The loading and unloading operations of different sizes of rotor cups 6 avoid the tediousness and limitations of manual adaptation, enhancing the versatility of the equipment. In addition, the automated operation of the robotic arm completely avoids the safety hazards that may be caused by manual operation, such as the risk of contact when the turntable 3 is in operation, improving the safety and reliability of the equipment operation. This design is deeply integrated with the automated layout of the multi-station turntable 3 in claim 1, forming an "unmanned" inspection production line, fundamentally solving the problems of low efficiency and positioning deviation caused by the reliance on manual labor in traditional equipment, and providing stable and reliable front-end support for the high-precision and large-scale inspection of rotor cups 6.

[0039] The scheme is further optimized. The clamping assembly 7 includes a clamping bracket 701, a fixing column 702, and a clamping telescopic cylinder 703. The clamping bracket 701 is C-shaped. The fixing column 702 is fixed to the top of the clamping bracket 701 and located above the working platform 2. The clamping telescopic cylinder 703 is fixed to the bottom of the clamping bracket 701 and located below the working platform 2. The bottom of the fixing column 702 has an insertion hole 704 corresponding to the mandrel 5. The top of the clamping telescopic cylinder 703 has an ejection column 705 corresponding to the mandrel 5. When the clamping telescopic cylinder 703 extends, the ejection column 705 can insert the top of the mandrel 5 into the insertion hole 704.

[0040] The clamping assembly 7 structure, through bidirectional mechanical constraint and controllable power transmission design, significantly improves the connection stability between the rotor 6 and the mandrel 5 and the reliability of the testing process.

[0041] This component uses a C-shaped clamping bracket 701 to form a stable support structure across the workstations. The insertion hole 704 of the top fixing column 702 is aligned vertically with the ejector column 705 of the bottom clamping telescopic cylinder 703, and mates with the top of the mandrel 5. When the turntable 3 transports the rotating cup 6 to the clamping station, the clamping telescopic cylinder 703 extends upward, and the ejector column 705 pushes the mandrel 5 to move upward along the axis of the workstation, so that the top of the mandrel 5 is inserted into the insertion hole 704 of the fixing column 702. This is achieved through the "bottom telescopic cylinder lifting + top fixing column 702 limiting" mechanism. The bidirectional clamping force further locks the interference fit between the mandrel 5 and the small-diameter opening of the rotor 6, forming an axially rigid fixation. Simultaneously, the clearance fit between the positioning pin 4 and the large-diameter opening of the rotor 6 provides a radial positioning reference. Together, these two elements construct a three-dimensional constraint system of "radial positioning + axial clamping," completely solving the problem of axial offset or circumferential wobbling of the rotor 6 during rotation caused by single-point clamping in traditional equipment. This ensures that the rotor 6 maintains a stable posture during high-speed rotation at the testing station, enabling the dial indicator to accurately capture true runout and fluctuation data. Furthermore, from a technical perspective, the automated control of the clamping telescopic cylinder 703 can precisely adjust the clamping force according to the material and size of the rotor 6, avoiding damage from overpressure or connection failure due to insufficient pressure, demonstrating strong compatibility. The clamping process is synchronized with the rotation of the turntable 3 station, requiring no manual intervention. Combined with the multi-station assembly line design, this greatly improves overall testing efficiency, providing reliable mechanical support for the high-precision, batch testing of the rotor 6, fundamentally solving the technical bottlenecks of unstable positioning and uncontrollable clamping force in traditional equipment.

[0042] The scheme is further optimized. The detection component 8 includes a detection bracket 801, a rotating column 802, and a detection telescopic cylinder 803. The rotating column 802 is fixed to the top of the detection bracket 801 and is located above the work platform 2. The detection telescopic cylinder 803 is fixed to the bottom of the detection bracket 801 and is located below the work platform 2. After the detection telescopic cylinder 803 extends, it can lift the mandrel 5 and make it abut against the bottom of the rotating column 802. The rotating column 802 is used to drive the mandrel 5 that abuts against it to rotate. A dial indicator is fixed on the detection bracket 801 corresponding to the rotating cup 6.

[0043] Furthermore, the rotating column 802 is driven by a motor and can rotate. The dial indicator is existing equipment and is not shown in the figure.

[0044] The detection component 8, through its vertically linked drive mechanism and precision measurement design, significantly improves the stability and accuracy of the rotor 6 runout detection. The detection component 8, via the detection bracket 801, constructs a rigid, layered support structure. The bottom telescopic cylinder 803 pushes the spindle 5 upwards, ensuring its top end is tightly against the drive end face of the top rotating column 802, forming a "push-down, connect-up" power transmission path. When the piston rod of the telescopic cylinder 803 extends, the spindle 5 is lifted and rigidly contacts the rotating column 802. The rotational motion of the rotating column 802 is synchronously transmitted to the spindle 5 through friction or the end face tooth structure, thereby driving the rotor 6 to rotate at high speed. This center-driven design of the spindle 5 avoids circumferential vibration or axial misalignment that may occur when the turntable 3 rotates, making the rotor 6 rotate more smoothly and ensuring stable contact between the dial indicator probe and the outer surface of the rotor 6. The dial indicator fixed on the frame 801 can accurately capture the radial runout and end face runout data of the rotor 6, greatly improving the measurement accuracy compared to traditional methods. The controllable stroke of the detection telescopic cylinder 803 allows for adjustment of the contact force between the mandrel 5 and the rotating column 802, ensuring reliable power transmission while avoiding deformation of the rotor 6 due to overpressure. It is compatible with the detection of rotor 6 of different materials and sizes. In addition, this structure integrates the drive mechanism rotating column 802, the detection telescopic cylinder 803, and the measuring mechanism dial indicator into the same bracket, forming an independent modular unit. This facilitates installation and debugging and allows for synchronous linkage with the rotary table 3 station, realizing an automated process of "lifting-rotating-detecting-resetting". The single detection cycle is shortened, effectively solving the technical problems of unstable drive, low measurement accuracy, and poor compatibility of traditional detection equipment. This provides core technical support for the precise quantitative detection of rotor 6 quality.

[0045] The scheme is further optimized so that the output end of the rotating column 802 and the output end of the detection telescopic cylinder 803 are both fixedly connected to the ejector pin 804, and the upper and lower bottom surfaces of the spindle 5 are provided with limit holes 10, and the ejector pin 804 matches the limit hole 10.

[0046] The fitting structure of the ejector pin 804 and the limiting hole 10, through a precision mechanical rigid connection design, further improves the positioning accuracy and power transmission reliability of the detection process: the ejector pins 804 at the output end of the rotating column 802 and the output end of the detection telescopic cylinder 803 are precisely matched with the limiting holes 10 on the upper and lower bottom surfaces of the mandrel 5, respectively. When the detection telescopic cylinder 803 lifts the mandrel 5, the upper and lower ejector pins 804 are simultaneously inserted into the limiting holes 10, forming a rigid positioning constraint and torque transmission path at both ends, completely eliminating the axial movement and circumferential slippage problems that may exist in the traditional contact method; the tip of the ejector pin 804 fits with the conical or cylindrical surface of the limiting hole 10, ensuring that the axis of the mandrel 5 is strictly coaxial with the axis of the rotating column 802. Even when the rotor 6 rotates at a high speed of tens of thousands of revolutions per minute, the axial deviation caused by centrifugal force can be controlled within the micrometer level, enabling the dial indicator to achieve precise measurement. The system accurately captures the true runout and runout of the rotating cup 6, improving measurement accuracy by more than 50% compared to traditional friction-driven methods. This structure combines positioning and transmission functions; the rigid connection of the ejector pin 804 enables lossless transmission of the rotational torque of the rotating column 802, resulting in minimal speed uniformity error and meeting the stable speed requirements of high-precision testing. Furthermore, by replacing different specifications of the ejector pin 804 and the limiting hole 10 components, it can quickly adapt to various models of the rotating cup 6, enhancing equipment compatibility through modular design. The ejector pin 804's automated extension and retraction with the detection telescopic cylinder 803 is precisely synchronized with the rotation of the turntable 3, significantly improving the continuity and efficiency of the testing process. This fundamentally solves the problems of measurement data distortion and poor adaptability caused by unstable drives in traditional testing equipment, providing key technical support for high-precision quantitative testing of the geometric accuracy of the rotating cup 6.

[0047] Further optimization of the scheme: the separation component 9 includes a separation bracket 901, and a separation telescopic cylinder 902 is fixedly connected to the top of the separation bracket 901. The movable end of the separation telescopic cylinder 902 corresponds to the top of the spindle 5, and when the separation telescopic cylinder 902 expands, it can push the spindle 5 away from the rotating cup 6 and slide downward.

[0048] The separation component 9, through its top-driven automated separation design, effectively solves the reliability and efficiency issues in the separation process between the rotor 6 and the mandrel 5: the separation bracket 901 is fixed above the turntable 3, and the separation telescopic cylinder 902 is vertically downward, with its movable end precisely aligned with the top of the mandrel 5. When the turntable 3 rotates to the separation station after the inspection is completed, the telescopic cylinder expands, driving the movable end to push the mandrel 5 downward, causing the mandrel 5 to disengage from the interference fit with the small-diameter opening of the rotor 6 along the axis of the station. This top-down vertical separation method avoids scratches on the inner wall of the rotor 6 or bending deformation of the mandrel 5 caused by uneven force during the separation process. The separation force is transmitted through the axis of the mandrel 5. Uniform transmission ensures smooth and unhindered operation; the stroke and thrust of the separation telescopic cylinder 902 can be precisely adjusted by the control system to adapt to different interference fits between the rotor 6 and the spindle 5, ensuring strong compatibility; this structure, together with the rotary table 3 station rotation and the robotic arm loading and unloading components, forms an automated closed loop, completing the "detection-separation-unloading" process without manual intervention, significantly improving detection efficiency. At the same time, the modular design of the separation bracket 901 facilitates maintenance and component replacement, fundamentally solving the technical pain points of traditional equipment separation processes that rely on manual labor and are prone to component damage, providing efficient and reliable mechanical support for rapid unloading and cyclic detection after rotor 6 detection.

[0049] The design was further optimized so that the top of mandrel 5 is tapered.

[0050] The conical top forms an automatic centering guide fit with the insertion hole 704 of the fixed post 702 of the clamping assembly 7, the ejector post 705, or the movable end of the telescopic cylinder of the separation assembly 9. During clamping, the conical tip guides the mandrel 5 to quickly align with the insertion hole 704, so that the ejector post 705 can be smoothly inserted without precise lateral alignment, shortening the single clamping alignment time. During separation, the inclined curved surface of the conical top guides the thrust of the telescopic cylinder to be evenly transmitted along the axis of the mandrel 5, avoiding the lateral stress concentration that may be caused by traditional planar contact, and improving the smoothness of the separation action. After separation, the conical side corresponds to the small diameter opening of the rotor 6, which facilitates the unloading of the rotor 6 and prevents the deformation of the mandrel 5 or the scratching of the inner wall of the rotor 6 during the unloading process. From the mechanical structure level, it provides key support for the efficient and reliable operation of the clamping and separation process, and further optimizes the automation level and component durability of the rotor 6 detection process.

[0051] The scheme is further optimized so that the turntable 3 is driven by a rotating motor and the turntable 3 is spaced apart from the working platform 2, so that when the spindle 5 is separated from the rotating cup 6, the bottom of the spindle 5 abuts against the top surface of the working platform 2, and when the spindle 5 is engaged with the rotating cup 6, the bottom of the spindle 5 is higher than the top surface of the working platform 2.

[0052] The rotating motor drives the turntable 3 to achieve precise flow of the workstation. The interval setting allows the mandrel 5 to present different postures at different workstations. When the mandrel 5 is engaged with the rotating cup 6, its bottom is higher than the top surface of the working platform 2, avoiding interference from the platform on the rotation of the mandrel 5. When the mandrel 5 is separated from the rotating cup 6, the bottom of the mandrel 5 abuts against the top surface of the working platform 2, forming a stable mechanical support benchmark, preventing the mandrel 5 from falling out of the limiting range of the positioning column 4. This prepares for the cyclic operation of the inspection work, provides a solid mechanical foundation for the full automation of the rotating cup 6 inspection process, and also ensures the high efficiency and stability of the equipment operation from the perspective of spatial structure.
