Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotating component manufacturing technology, and specifically to a production line for the production of rotating components. Background Technology
[0002] A crankshaft torsional vibration damper (also known as a torsional vibration damper or harmonic vibration damper, abbreviated as TVD) is a device installed at the front end of the engine crankshaft (usually integrated with a pulley) to suppress the torsional vibration of the crankshaft, protect critical engine components, prevent crankshaft from breaking due to resonance by absorbing or offsetting periodic torque fluctuations, and reduce noise and vibration (NVH) to improve NVH performance.
[0003] A typical TVD (Transmission Controlled Discharge) consists of the following components: an inertial mass block (flywheel), elastic elements (rubber / silicone oil / springs), and a housing (integrated with pulleys). The inertial mass block (flywheel) provides inertial torque to counteract vibrational energy. The elastic elements (rubber / silicone oil / springs) connect the inertial mass block to the housing, absorbing vibrations through elastic deformation. The housing (integrated with pulleys) is directly mounted on the front end of the crankshaft to transmit power to accessory systems (such as alternators and air conditioning compressors).
[0004] In the TVD production assembly process, the various components must first be assembled into a complete structure. Then, the assembled product needs to be cleaned and inspected. After passing inspection, it is packaged. In the existing production workshop, the assembly, cleaning, inspection, and packaging processes are all operated independently. Workpieces are manually transferred between processes, resulting in a fragmented workflow, low production efficiency, and an efficiency loss of approximately 40%. Utility Model Content
[0005] The technical problem solved by this utility model is that the various processes in the existing TVD assembly production process are relatively isolated, resulting in low production efficiency.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A production line for producing rotating parts includes:
[0008] Digital display press;
[0009] A cleaning machine, used for cleaning products;
[0010] A dynamic balancing machine, used for dynamic balancing testing of products;
[0011] A vibration detection device, used to detect vibration in a product;
[0012] The digital display press is connected to the cleaning machine via a first conveying device, the cleaning machine is connected to the dynamic balancing machine via a second conveying device, the dynamic balancing machine is connected to the runout detection device via an appearance inspection station, and the output end of the runout detection device is connected to a packaging station.
[0013] In one embodiment of this utility model: both the first conveying device and the second conveying device are belt conveyors.
[0014] In one embodiment of this utility model: a handling mechanism is provided between the output end of the second conveying device and the dynamic balancing machine.
[0015] In one embodiment of this utility model: the cleaning machine is an ultrasonic cleaning device.
[0016] In one embodiment of this utility model, the cleaning pressure of the high-pressure spraying process of the cleaning machine is 25 MPa.
[0017] In one embodiment of this utility model: a first defective product area is provided on the side of the output end of the dynamic balancing machine.
[0018] In one embodiment of this utility model: a second defective product area is provided on the side of the output end of the vibration detection device.
[0019] In one embodiment of this utility model: both the first defective product area and the second defective product area are provided with a receiving frame.
[0020] In one embodiment of this utility model: the vibration detection equipment is an integrated machine for vibration detection, marking, and oiling.
[0021] In one aspect of this utility model: during the operation of the runout detection equipment, when the runout is greater than 0.25mm, the non-conforming product management mode is activated.
[0022] The production line for producing rotating components according to this utility model has at least one of the following technical effects:
[0023] In this application, by arranging the various processes sequentially in a straight line and connecting them through conveyor equipment, the processes are integrated into a whole, effectively shortening the time consumption for workpiece transfer between adjacent processes and greatly improving the overall production efficiency. This solves the problem of fragmented processes and low production efficiency in existing assembly production processes. A runout inspection machine integrating running, marking, and oiling is used for product runout inspection, greatly improving process integration and automation. Compared to existing manual runout inspection methods, it significantly improves efficiency and inspection accuracy. Manual runout tooling inspection leads to increased runout detection errors (measured deviation ≥ 0.05mm). Simultaneously, a non-conforming product storage area is provided, and a local area network is set up in conjunction with the MES system. Each product / material / work order generates a unique QR code (including ID, batch, process parameters, etc.), which can be scanned to obtain the entire process parameters and inspection report. This effectively ensures data connectivity between different processes and links, guarantees quality traceability efficiency, and allows for timely adjustments to previous processes.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] Please see Figure 1-4 This utility model relates to a production line for manufacturing rotating components, comprising a digital display press 1, a cleaning machine 3, a dynamic balancing machine 5, and a runout inspection device 9. The digital display press 1 is used to press and assemble various components into a single product. The cleaning machine 3 is used to clean the assembled product; the dynamic balancing machine 5 is used to perform dynamic balancing tests on the cleaned product; and the runout inspection device 9 is used to inspect the runout quality of the product.
[0034] Please see Figure 1-4 In one embodiment of this utility model, a first conveying device 2 is provided between the digital display press 1 and the cleaning machine 3, a second conveying device 4 is provided between the cleaning machine 3 and the dynamic balancing machine 5, an appearance inspection station 8 is provided between the dynamic balancing machine 5 and the runout detection device 9, and a packaging station 11 is provided at the output end of the runout detection device. By arranging each process in a straight line in sequence and connecting them through conveying devices, the processes are integrated, effectively shortening the time consumption between adjacent processes and greatly improving the overall production efficiency of the product.
[0035] Please see Figure 1-4 In one embodiment of this utility model, the workpiece conveying method (i.e., conveying equipment) between two adjacent processes can be a conveyor belt, a magnetic levitation track, or an AGV trolley. However, considering that the cost of conveying workpieces using a magnetic levitation track or AGV trolley is high, and the maintenance complexity and difficulty are also high, as a preferred example, both the first conveying device 2 and the second conveying device 4 are belt conveyors. A handling mechanism 6 can also be provided between the output end of the second conveying device 4 and the dynamic balancing machine 5, for accurately conveying the workpiece to the position of the dynamic balancing machine 5 for dynamic balancing testing. The handling mechanism 6 can be a (six-axis) robot or a small gantry mechanism.
[0036] Please see Figure 1-4 In one embodiment of this utility model, the cleaning pressure of the high-pressure spray process of the cleaning machine 3 can be 25 MPa. Simultaneously, the cleaning machine 3 can also be equipped with an ultrasonic unit, enabling it to function as an ultrasonic cleaning device and ensuring effective cleaning. In actual production, dry ice cleaning equipment can also be selected because it offers superior environmental performance; however, it is more expensive than ultrasonic cleaning equipment and is not suitable for removing internal debris. Users can choose according to their actual production needs.
[0037] Please see Figure 1-4 In one embodiment of this utility model, a first non-conforming product area 7 can be provided on the side of the output end of the dynamic balancing machine 5. A second non-conforming product area 10 can be provided on the side of the output end of the runout inspection device 9. Both the first non-conforming product area 7 and the second non-conforming product area are provided with receiving frames. By providing non-conforming product areas for placing non-conforming products, it is convenient for quality control and subsequent diversion processing of non-conforming products. Similarly, a corresponding non-conforming product area can also be provided at the appearance inspection station 8. The runout inspection device 9 is an integrated machine for runout, marking, and oiling. After runout inspection, qualified products are directly marked and oiled, and then output to the packaging station 11 for packaging. During the operation of the runout inspection device 9, when the runout amount > 0.25mm, the non-conforming product management mode is activated.
[0038] Please see Figure 1-4 In one embodiment of this utility model, the integrated runout, marking, and oiling machine is used to measure the radial / axial runout of the TVD's outer circle / end face, engrave QR codes / serial numbers (for MES traceability), and spray rust-preventive oil / lubricating grease (e.g., micro-spraying 0.1-0.3g) onto the TVD's mating surfaces. As an example, selectable brands and models include: SCHENCK's VSR 5000-TVD, ZKJ-TVD300 from Zhongke Micro-Precision (China), HANS-TVD Pro from Han's Laser (China), etc. Users can also select appropriate equipment according to their needs. The dynamic balancing machine 5 can be a brand and model such as: SCHENCK's H50V / H65V, Hofmann's HBM-30 / HBM-50, CEMB's CEMBN600, or other equipment capable of dynamic balancing testing.
[0039] Please see Figure 1-4In one embodiment of this utility model, a local area network can be set up in the production line area, along with corresponding network devices and a database. Each product / material / work order generates a unique QR code (containing ID, batch number, process parameters, etc.), managed using an MES system. Workers at each stage upload product-related data (such as quality inspection status, time, batch number, process, etc.) to the database. Other workers can directly scan the code to obtain the data when needed, facilitating quality traceability. Simultaneously, the equipment on the production line, including the digital display press 1, cleaning machine 3, dynamic balancing machine 5, and runout detection equipment 9, is networked to obtain the working status of the relevant equipment and product testing data, facilitating production planning and traceability of (problematic) products.
[0040] The working principle of this utility model:
[0041] This application applies to the automated production of rotating components such as gearbox flywheels and motor rotors. As an example, this application describes TVD production. During production, the various components of the product are first pressed using a digital display press 1. The pressed products are then placed onto a conveyor belt (first conveying device 2) and flow into an automatic cleaning line (cleaning machine 3) for cleaning. After cleaning, the products flow out. A second conveying device 4 is installed at the output end of the cleaning machine 3. The products are then transported via a conveyor belt (second conveying device 4) and transported to a dynamic balancing machine 5 by a handling mechanism 6 for weight reduction and dynamic balancing. Simultaneously, the weight-reduced products are re-tested. After testing, defective parts flow into the dynamic balancing NG area (first defective product area 7), while qualified parts flow into the appearance workstation for manual appearance inspection. Products that pass the appearance inspection are placed into a vibration inspection device 9 for vibration, marking, and oiling. Violations due to vibration flow into the vibration NG area (second defective flat area). Qualified vibration parts are marked, oiled, and then enter the packaging workstation. For example, the dynamic balancing speed range can be 500-4000 rpm, but it can also be set according to the actual product requirements.
[0042] In this application, by arranging the various processes sequentially in a straight line and connecting them through conveyor equipment, the processes are integrated into a whole, effectively shortening the time consumption for workpiece transfer between adjacent processes and greatly improving the overall production efficiency. This solves the problem of fragmented processes and low production efficiency in existing assembly production technologies. A runout inspection machine integrating running, marking, and oiling is used for product runout inspection, significantly improving process integration and automation. Compared to existing manual runout inspection methods, it greatly improves efficiency and inspection accuracy. Manual runout tooling inspection leads to increased runout detection errors (measured deviation ≥ 0.05mm). Simultaneously, a non-conforming product storage area is provided, and a local area network is set up in conjunction with the MES system. Each product / material / work order generates a unique QR code (including ID, batch, process parameters, etc.), which can be scanned to obtain the entire process parameters and inspection report. This effectively ensures data connectivity between different processes and links, guarantees quality traceability efficiency, and allows for timely adjustments to previous processes.
[0043] The applicant continuously produced 5,000 TVD tests: the equipment downtime (MTBF) reached 1,200 hours, with a false positive rate of 0.05%. The single-piece production cycle was reduced from 15 minutes to 4.5 minutes, and the overall equipment utilization rate was ≥92%. The runout detection pass rate increased from 90.3% to 99.8%. Labor costs were reduced by 74%; compared to the previous fragmented process, five fewer workers could be required under the same conditions, resulting in 28% energy savings. Quality data was uploaded in real time, and the time to locate abnormal batches was reduced from 2 hours to 5 minutes. Traceability was significantly improved.
