Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to an automatic oiling device for motor rotors. Background Technology

[0002] The motor rotor is an important component of the motor. Its surface often needs to be rust-proofed after processing to ensure that it does not oxidize or corrode during transportation, storage and subsequent assembly. Rust-preventive oil is widely used for rotor surface protection because of its good penetration, adhesion and protection. Traditional treatment methods mainly include brushing, dipping and spraying. Among them, spraying has gradually become the mainstream process because of its uniform coverage and high efficiency. Especially on mass production lines, the rust-preventive oil spraying process has become a key link in the rotor manufacturing process.

[0003] Currently, the application of anti-rust oil to motor rotors relies heavily on manual handling and spraying with guns. The cycle time is subject to fluctuations due to human factors, making it difficult to guarantee the uniformity and consistency of the coating. The open spraying environment has poor sealing, and oil mist and odor gases can easily escape, affecting the health of operators and increasing the cleaning burden of the workshop. After spraying, there is a lack of systematic guidance and recycling channels for excess oil, which often results in dripping, overflowing and residue, causing material waste and equipment pollution.

[0004] In terms of spraying precision, traditional nozzles are mostly fixed sprayers and lack dynamic lifting and adjustment functions. During the spraying process, it is difficult to keep the relative distance between the nozzle and the rotor consistent, which affects the uniformity of spraying. In addition, most devices do not integrate flow and pressure monitoring devices, making it difficult to control the spraying volume in real time, which can easily cause uneven oil film thickness, thereby affecting the rust prevention effect of the rotor and the consistency of the product.

[0005] In summary, although the existing rotor anti-rust oil spraying process has been widely used, there are still significant shortcomings in terms of automated loading and unloading, sealing of the spraying operation, oil mist treatment, oil recovery, and spraying accuracy control. Utility Model Content

[0006] In view of the above-mentioned defects in the prior art, this utility model provides an automatic oiling device for electric motor rotors, which aims to solve the problems of low automation, poor sealing in the oiling process, imperfect oil mist treatment, insufficient oil recovery, and insufficient control of spraying precision in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic oiling device for an electric motor rotor, comprising a machine base, a loading and unloading device disposed on the machine base, an oiling operation device disposed on the machine base and located at one end of the loading and unloading device, a movable clamping device disposed on the machine base and located on one side of the oiling operation device, and an oil storage tank. The loading and unloading device includes a loading platform and an unloading platform arranged parallel to the loading platform. The oiling operation device includes a first lifting drive device disposed on the machine base, a protective cover disposed at the output end of the lifting drive device, a rotary processing table disposed inside the protective cover, and a lifting oiling nozzle fixed to the inner side of the upper end face of the protective cover and facing the rotary processing table. The lifting oiling nozzle is connected to the oil storage tank. The movable clamping device transfers the product to be processed on the loading platform to the rotary processing table for oiling operation, and after the oiling operation is completed, transfers the processed product to the unloading platform.

[0008] Based on the above structural design, this utility model can realize the automated processing of rust-preventive oil spraying on motor rotors. The loading and unloading device and the moving clamping device work together to enable the rotor to complete a continuous process from loading to oiling and then unloading on the machine, avoiding manual intervention and improving cycle stability. The protective cover forms a closed working space during the oiling process, which can suppress the escape of oil mist and harmful gases, and facilitates connection with an external fume processor to improve the working environment. The rotating processing table works in conjunction with the lifting oiling nozzle fixed on the inner side of the upper end face of the protective cover. The spraying distance and angle are kept stable by the rotation of the workpiece and the adjustment of the nozzle height, thereby improving the uniformity and consistency of the rust-preventive oil film. The oil storage tank is connected to the lifting oiling nozzle to provide stable oil supply for the spraying process, ensuring the spraying quantity and spraying quality.

[0009] Furthermore, the oiling device also includes a first oil baffle, a guide funnel, an oil leakage hole, a return oil pipe, a waste oil tank, a second oil baffle, a third oil baffle, and a sealing ring. The first oil baffle is fixed inside the upper surface of the protective cover and covers the upper surface of the product to be processed. The upper surface of the rotary processing table is provided with a plurality of oil leakage holes. The guide funnel is provided below the oil leakage holes. The guide funnel is connected to the return oil pipe. The return oil pipe extends into the machine tool and connects to the waste oil tank. The third oil baffle is fixed on the machine tool. The second oil baffle is fixed on the third oil baffle. The second oil baffle and the third oil baffle together surround the rotary processing table. The size of the sealing ring is adapted to the lower end of the protective cover and is provided on the third oil baffle.

[0010] Based on the above, the first oil baffle covers the upper surface of the product to be processed, which can shield non-target areas and prevent the upper surface from being sprayed. The oil leakage hole, the guide funnel below it, and the return oil pipe form a continuous drainage path, which concentrates the oil that has not condensed or is excess during the spraying process into the waste oil tank, reducing material waste and reducing oil accumulation on the machine. The third oil baffle set on the machine and the second oil baffle installed on it together form a circumferential protective boundary on the outer periphery of the rotating processing table, which suppresses the outward spread of splashes and drips and keeps the working area clean. The sealing ring arranged on the third oil baffle is adapted to the size of the lower end of the protective cover, and forms a circumferential sealing fit when the protective cover is lowered, which can improve the sealing of the oiling cavity, reduce the leakage of oil mist and harmful gases, and achieve efficient extraction in conjunction with external fume treatment.

[0011] Furthermore, the movable clamping device includes a lateral displacement device disposed on the machine base, a longitudinal displacement device disposed on the lateral displacement device, a second lifting drive device mounted on the longitudinal displacement device, and a clamping assembly disposed at the output end of the second lifting drive device.

[0012] Based on the above, the lateral displacement device and the longitudinal displacement device form a planar orthogonal kinematic chain, which, together with the second lifting drive device, realizes the three-axis pick-and-place path of the clamping component. Under the coordinated action of lifting, lateral movement and longitudinal movement, the clamping component can accurately transfer the product to be processed from the loading platform to the rotary processing table, and after oiling, transfer the processed product to the unloading platform. The entire handling process has high positioning repeatability and reliable alignment, which can effectively shorten the cycle time and reduce the fluctuations caused by manual intervention. At the same time, non-interference pick-and-place is completed with the opening and closing of the protective cover, ensuring the continuity and stability of the oiling station.

[0013] Furthermore, two pole-mounted sensors are installed on the machine platform between the loading platform and the unloading platform. The two pole-mounted sensors detect whether there are products placed on the loading platform and the unloading platform, respectively.

[0014] Based on the above, the two pole-mounted sensors can detect the status of the workpieces on the loading and unloading platforms respectively. When a product to be processed is detected on the loading platform, the control system can drive the moving clamping device to perform pick-up and place actions. Only after confirming that the unloading platform is empty is the processed product allowed to be transferred and placed, thereby realizing intelligent judgment and cycle interlocking of the loading and unloading process, avoiding process disorder caused by mis-picking or mis-placing, and improving the automation level and reliability of equipment operation.

[0015] Furthermore, the first lifting drive device is equipped with a sensor located on the outside of the protective cover, which is used to detect whether the protective cover is in a closed state.

[0016] Based on the above, the sensor can provide real-time feedback of status signals when the protective cover is lowered and closed. The control system determines whether the oiling operation area has formed a sealed environment based on this signal. Only when the protective cover is in a safe closed state is the lifting oiling nozzle and rotating processing table allowed to enter the spraying process, thereby avoiding oil mist leakage or safety hazards caused by spraying under non-sealed conditions, and improving the safety and reliability of the operation process.

[0017] Furthermore, a flow meter, a pressure regulator, a flow controller, and a flow monitor are provided on the rear side of the first lifting drive device to adjust and monitor the oil supply pressure and flow rate of the lifting oiling nozzle.

[0018] Based on the above, the flow meter, pressure regulator, flow controller, and flow monitor constitute an online adjustment and real-time monitoring unit for the oil supply parameters of the lifting oiling nozzle. It can stabilize the oil supply pressure and flow during the spraying process, maintain the atomization state and spray volume within the set range, thereby ensuring that the thickness and uniformity of the rust-preventive oil film are consistent. When abnormal pressure, flow fluctuations, or blockage tendencies occur, it can promptly provide feedback and trigger protection logic such as speed limiting or spray stop, reducing material waste and workstation contamination caused by overspray and underspray, and improving the stability of spraying quality and process safety.

[0019] Furthermore, the upper part of the protective cover has a through hole, and a pipe is fixedly connected to the through hole, which is connected to an external smoke processor.

[0020] Based on the above, the through holes and pipes connect the inside of the protective cover with the external fume processor. During the oiling operation, the oil mist and smoke inside the cover can be continuously extracted, reducing the escape of oil mist and achieving linkage treatment in conjunction with the closed state of the protective cover. This improves the air quality in the work area, reduces the deposition of volatile substances on the equipment surface, and enhances the cleanliness of the work station and operational safety.

[0021] Furthermore, the machine platform is provided with a plurality of limiting handles, which are respectively located at the edges of the loading platform and the unloading platform, for limiting and fixing the loading platform and the unloading platform on the machine platform.

[0022] Based on the above, the limit handle not only limits and clamps the loading and unloading platforms at the edges to ensure no displacement during operation, but also unlocks and repositions the platforms by adjusting the tightness. This eliminates the need for additional tools for disassembling, replacing, and maintaining the platforms, shortening tooling changeover and maintenance time. The repeatable positioning characteristic of the limit handle ensures that the platform is consistent with the machine's reference when it is locked again, reducing the alignment error of picking and placing and improving cycle stability, thus taking into account both operational reliability and the need for rapid line changeover.

[0023] Furthermore, the machine tool is equipped with a processing table sensor, which is located at a position opposite to the processing table and is used to detect the operating status of the processing table.

[0024] Based on the above, the machining table sensor can detect the machining status on the rotating machining table in real time and feed the detection signal back to the control system to realize the monitoring and protection of the machining process.

[0025] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0031] The first lifting drive device 30 is equipped with a sensor 7, which is located on the outside of the protective cover 31 and is used to detect whether the protective cover 31 is in a closed state.

[0032] The first lifting drive device 30 is provided with a flow meter 10, a pressure regulator 11, a flow controller 12 and a flow monitor 13 on its rear side, which are used to adjust and monitor the oil supply pressure and flow rate of the lifting oiling nozzle 33.

[0033] The upper part of the protective cover 31 has a through hole, and a pipe is fixedly connected to the through hole. The pipe is connected to an external smoke processor 8.
