Description

Technical Field

[0001] This utility model relates to the field of bearing cage lubrication technology, specifically to an automatic integrated device for vacuum immersion and oil slinging of a space bearing cage. Background Technology

[0002] With the rapid development of the aerospace industry, the requirements for the performance parameters of space bearings, such as rotational speed, load capacity, and precision, are also increasing. Lubricating oil plays a crucial role in bearing performance during high-speed operation. Bearings rely on the lubricating oil absorbed by the cage during immersion for lubrication. However, more oil absorption by the cage is not necessarily better; excessive oil will not only fail to provide lubrication but will also generate resistance and heat. There are strict standards for the amount of oil absorbed by the cage during immersion, so a rigorous immersion and oil removal process is necessary to ensure the correct oil content in the cage.

[0003] In existing technologies, separate oil immersion devices and oil-scraping equipment are required. The process from oil immersion to oil-scraping necessitates operators transferring the retainer from the immersion device to the oil-scraping equipment. This transfer process is time-consuming, inevitably leading to waste of time and manpower. Furthermore, the oil immersion process requires heating the lubricating oil and the retainer, which can easily cause burns to workers during the transfer process, resulting in safety accidents.

[0088] See Figure 5 and Figure 6Electronic balance 4-1 weighs cage 2-1. Electronic balance 4-1 is fixedly connected to shock absorber 4-2. Balance support 4-3 is set on top of electronic balance 4-1.

[0103] Vacuum pump 5-12, which is connected to oven body 5-1 via vacuum valve 5-13;

[0104] The oven cover motor 5-7 is connected to the oven frame 5-3 and controls the opening and closing of the oven cover 5-2;

[0105] The oven cover 5-2 is connected to the oven cover motor 5-7 to ensure the airtightness of the oven body;

[0106] Heating wire 5-5 is fixedly connected to the oven cover 5-2 and provides a heat source for baking the holder 2-1;

[0107] The oven frame 5-3 provides support and is fixedly connected to the overall frame of the gantry rotating mechanism 3.

[0108] The oven tray 5-4 is designed with 6 rows of grooves and 4 columns of grooves, forming a total of 24 cross points. Each groove is chamfered to facilitate the sliding of the cage fixture 2-2 into the cross points.

[0109] The oil tank 5-8 can be raised and lowered via the oil tank lifting platform 5-9 under the action of the oil tank lifting motor and electric cylinder 5-6, thereby realizing the oil immersion and oil draining process of the retainer 2-1. The oil tank lifting platform 5-9 moves along the oil tank slide rail 5-10 of the oven body 5-1 via the oil tank pulley 5-11.

[0110] See Figure 11 , Figure 12 and Figure 13 The centrifugal oil slinging system 6 mainly consists of an oil slinger, which is composed of an oil slinger body 6-1 and an oil slinger cover 6-2. The oil slinger motor 6-3, rotor 6-4, and oil cup 6-5 are located inside the oil slinger body 6-1.

[0111] The oil slinger body 6-1 provides support and is fixedly connected to the overall frame 3-3 of the gantry operating mechanism 3.

[0112] The top cover 6-2 of the oil slinger is connected to the body 6-1 of the oil slinger and has a square window that can be opened and closed. The robotic arm can pick up and put down the retainer 2-1 through the window.

[0113] The oil slinger motor 6-3 is connected to the oil slinger body 6-1 and provides rotational force.

[0114] Rotor 6-4 is connected to oil slinger motor 6-3. The axis of rotor 6-4 coincides with the axis of oil slinger motor 6-3 and rotates around the axis.

[0115] Oil cup 6-5 is hinged to rotor 6-4. When rotor 6-4 is not rotating, oil cup 6-5 naturally hangs down. Figure 12 The vertical position is shown; when rotor 6-4 rotates, oil cup 6-5 rotates with rotor 6-4, forming... Figure 11 As shown, the excess lubricating oil centrifuged from the storage holder 2-1 is stored in this state;

[0116] The rotor 6-4 of the oil slinger has six oil cups 6-5. Inside the oil cups 6-5 is a bearing retainer 6-6 with a cross groove to help fix the retainer 2-1 and the retainer fixture 2-2.

[0117] Therefore, when the centrifugal oil-slinging system 6 is in a non-slinging state, the oil cup 6-5 naturally falls down and becomes... Figure 12 The vertical position shown allows the robotic arm gripper 3-1 to easily remove the retainer 2-1 from the oil cup 6-5 through the window, or to insert the retainer 2-1 into the oil cup 6-5.

[0118] One method of using the automatic integrated vacuum oil immersion and oil slinging device for space bearing cages provided by this utility model is as follows:

[0119] When immersing and spitting out oil from cage 2-1:

[0120] The operator controls the pallet motor and electric cylinder 4-5 via the host computer to extend the pallet 4-4 along the pallet slide rail 4-7, place the retainer and tooling in the loading area of ​​the pallet 4-4, and then retract the pallet 4-4. The host computer is used to set the number of retainers, the acceptable oil content range, the oven operating temperature and time, and the oil slinger speed and time, and then starts the machine.

[0121] The robotic arm with vision camera 3-2 in the gantry rotating mechanism 3 first performs visual calibration. The YXZ axis motors of the gantry rotating mechanism 3 move sequentially to move the robotic arm with vision camera 3-2 to the coordinates of Mark point 4-12 for calibration, and obtain the accurate coordinates of each cage position.

[0122] The robotic arm with grippers moves to directly above the cage position via the YX-axis module. The Z-axis electric cylinder extends, causing gripper 3-1 to move to cage fixture 2-2. Gripper 3-1 clamps cage fixture 2-2, and the Z-axis electric cylinder retracts. Gripper 3-1 then moves cage 2-1 and cage fixture 2-2. The robotic arm sequentially moves each cage 2-1 and cage fixture 2-2 from the loading area of ​​tray 4-4 to oven tray 5-4, after which the robotic arm returns to its zero position.

[0123] The oven cover motor 5-7 closes the oven cover 5-2, the oil tank lifting motor and electric cylinder 5-6 raise the oil tank 5-8, the vacuum pump 5-12 is turned on to draw a vacuum and the heating wire 5-5 is started to heat and bake; after the oven has been working for a certain period of time, such as 4 hours, the vacuum pump 5-12 stops drawing a vacuum, the heating wire 5-5 stops heating, the oil tank lifting motor and electric cylinder 5-6 lower the oil tank 5-8, break the vacuum and open the oven cover 5-2;

[0124] The oil slinger opens its window, and the robotic arm with grippers moves the cage 2-1 and cage fixture 2-2 from the oven tray 5-4 to the oil cup 6-5 of the oil slinger. The robotic arm returns to the zero position, the oil slinger closes its window, reaches the set speed, and starts timing; for example, reaching 1000 r / min and counting down for 10 minutes. After the set running time of 10 minutes, the oil slinger decelerates and gradually stops. The oil slinger opens its window, and the robotic arm with grippers moves the cage 2-1 and cage fixture 2-2 from the oil cup 6-5 of the oil slinger to the balance support 4-3 of the electronic balance 4-1 for weighing.

[0125] If the weight increase is within the acceptable range, for example, a weight increase of 20%-30%, the oil content of the cage is considered acceptable, and the robotic arm automatically moves the cage 2-1 and cage fixture 2-2 from the weighing point of the balance to the acceptable area 4-10 on the tray. Otherwise, the oil content of the cage is considered unacceptable, and the robotic arm automatically moves the cage 2-1 and cage fixture 2-2 from the weighing point of the balance to the unacceptable area 4-11 on the tray. After weighing and dividing each cage 2-1 and cage fixture 2-2 in sequence, the robotic arm returns to the zero position, the oven closes its top cover, the oil-spinning mechanism opens, the tray 4-4 extends, and the cage 2-1 and cage fixture 2-2 in the acceptable area are removed. The cages in the unacceptable area are scrapped. The oil immersion and oil-spinning process of the cages is completed.

[0126] For example, this device can immerse 6 cages in oil in a vacuum oven system 5 for 4 hours, and then automatically distinguish whether they are qualified after being centrifuged in an oil-spinning system 6 at 1000 r / min for 10 minutes.

[0127] This invention provides an automated integrated device for vacuum oil immersion and oil removal of space bearing cages. From the perspective of immersion efficiency, it eliminates the steps of manual waiting and manual cage transfer during the immersion process, greatly improving the continuity between processes. From the perspective of immersion safety, it eliminates the need for manual contact with the high-temperature baked cage and lubricating oil, better avoiding potential injury to operators. From the perspective of immersion effect, immersion, oil removal, and weighing are all carried out within a closed device. The device's operating status and cage data can be obtained through a host computer, reducing external interference and human error, thereby improving the cage qualification rate.

[0128] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
