[0002] The motor shaft skeleton oil seal is a commonly used accessory on motors. This accessory is mainly assembled with the motor shaft. When the motor is assembled, the skeleton oil seal needs to be oiled, that is, paste lubricating oil is injected into the lip and spring parts of the oil seal. The current oiling method is mainly manual, which has many oiling defects, such as insufficient oiling or discontinuous oiling, which requires multiple reworks and affects normal production operations. Summary of the invention
[0003] The purpose of the present invention is to provide a special oiling machine for motor shaft skeleton oil seal, and the technical problem to be solved is: how to improve the oiling effect.

A guide rail and a blocking hemisphere are designed in the above cavity. The guide rail provides positioning for the inclined linear motion of the blocking hemisphere. The blocking hemisphere blocks the middle position of the inner cavity of the inner fixing part. The diameter of the inner cavity on one side of the inner fixing part is larger than the diameter of the blocking hemisphere, so that the blocking hemisphere does not block the middle inner cavity of the inner fixing part in the initial state without oil filling, blocks the middle inner cavity of the inner fixing part at the end of the oil filling state, and returns to the initial position, that is, the position of the side of the inner fixing part close to the opening, at the end of the oil filling state; The rotating cover is in rotational connection with the top of the base; The skeleton oil seal comprises a lip portion and a spring portion; wherein the lip portion corresponds to the first oil injection cavity, and the spring portion corresponds to the second oil injection cavity.

[0010] The beneficial effects of the present invention are: 1. By designing the oil pressure assembly and the battery oil pump, the oil paste is automatically fed to avoid manual operation; when the skeleton oil seal is placed on the extension part, the sensor triggers the induction, thereby driving the first cylinder and the battery oil pump to operate, thereby pouring the oil paste from the first oil injection chamber and the second oil injection chamber into the lip part and the spring part of the skeleton oil seal respectively; 2.

The inner cavity of the rotating cover is designed into an arc-shaped spraying structure. Under the action of a certain pressure of ointment, the rotating cover will rotate in a certain arc, thereby optimizing the original static oiling into dynamic rotating oiling, thereby significantly improving the oiling effect; 4. Through the design of the extension piece, it is a split structure with the base, which makes it easy to flexibly replace according to the outer diameter of the skeleton oil seal, so that one set of equipment can meet all current specifications of skeleton oil seals.

[0012] Please refer to Figure 1 and Figure 2 The motor shaft skeleton oil seal special oiling machine in the figure is designed with an oil pressure component 2, an electromagnetic oil pump 1, an oil delivery pipe 3, an oil blowing cylinder body 41, and an oil filling tool 5; the oil pressure component 2 is used to cooperate with the electromagnetic oil pump 1 and the oil delivery pipe 3 to realize the delivery of the oil paste 82 to the oil blowing cylinder body 41, and the air cylinder is used to deliver the oil paste to the main oil filling chamber 51 of the oil filling tool 5 under a certain air pressure, and the oil filling tool 5 is used to complete the oil filling operation of the skeleton oil seal 6; in actual applications, other components can be additionally added or the above components can be re-optimized.
[0013] In order to press down the oil paste 82, the oil pressure assembly 2 in the figure is respectively designed with a first cylinder 21, a pressure rod 22, an upper support rod 23, a lower support rod 24, a mounting plate 25, and an oil blocking plate structure. The first cylinder 21 drives the pressure rod 22 to press down, so that the upper support rod 23, the mounting plate 25, the lower support rod 24, and the oil blocking plate move downward, so that the electromagnetic oil pump 1 can always deliver the oil paste 82 to the oil blowing cylinder body 41. The first cylinder 21 in the figure is a conventional component, which has two and is installed longitudinally at intervals. The pressure rod 22 is one and is installed horizontally on the driving rods of the two first cylinders 21, so that it performs synchronous lifting and lowering movements with the first cylinder 21. The upper support rod 23 has two and is installed longitudinally at the lower position of the pressure rod 22 so as to move synchronously with the pressure rod 22. The mounting plate 25 has one and is installed horizontally at the bottom position of the upper support rod 23, and the mounting plate 25 is used to install the electromagnetic oil pump 1. The lower support rod 24 is installed below the mounting plate 25 and has two longitudinally spaced cases for mounting and fixing the blocking plate. The blocking plate is fixed on the lower support rod 24 and is used to block the barrel 81 storing the oil paste 82 to prevent oxidation or dust from falling into the oil paste 82. In practical applications, the above-mentioned oil pressure assembly 2 can also adopt other styles.
[0014] The electromagnetic oil pump 1 and the oil delivery pipe 3 in the figure are conventional components. The electromagnetic oil pump 1 is mounted on the mounting plate 25 as shown in the figure. The oil inlet of the electromagnetic oil pump 1 cooperates with the oil paste 82, and the oil outlet cooperates with the oil blowing cylinder 41, so that the oil paste 82 is sucked out of the barrel 81 and transported to the oil blowing cylinder 41. The electromagnetic oil pump 1 is controlled by the PLC controller 7. When the infrared sensor next to the oil blowing cylinder 41 senses that the skeleton oil seal 6 is placed, the electromagnetic oil pump 1 is driven to operate and perform the oil delivery action.
[0015] The oil blowing cylinder 41 in the figure is a conventional structure that cooperates with a high-pressure air source and an oil paste material. The oil blowing cylinder 41 has a cavity for temporarily storing the oil paste. The cavity also cooperates with an air pipe 42 that conducts the high-pressure air source. In this way, the high-pressure air cylinder is used to blow the oil paste temporarily stored in the cylinder toward the main oil filling chamber 51.
[0016] The oil filling tool 5 in the figure has multiple components, including a base 54, an extension part 55, an internal fixing part 56, a rotating cover 59 and other components.
[0017] The base 54 is fixed to the oil blowing cylinder body 41 , and has a main oil injection chamber 51 and a first branch oil injection chamber 52 inside. The first branch oil injection chamber 52 is arranged transversely and communicates with the main oil injection chamber 51 .
[0018] The extension piece 55 is a hollow ring structure, which is assembled with the base 54 in a separate structure. The diameter of the extension piece 55 can be determined according to the different types and specifications of the skeleton oil seal 6, so that one oil filling tool 5 can match all types of skeleton oil seals 6 currently on the market.
[0019] The internal fixing member 56 is a hollow annular structure, which is located between the top of the base 54 and the rotating cover 59, and has two symmetrically arranged irregular cavities inside to form a second oil injection cavity 53, which is arranged transversely and communicates with the main oil injection cavity 51. Specifically, the circular cavity with an opening at the end is larger than the diameter of the blocking hemisphere 57 and gradually shrinks inward to the middle position, and the diameter of the circular cavity at the middle position remains the same until it transitions to the other side, so that the inner cavity of the internal fixing member 56 is expanded at one end. A blocking hemisphere and a guide rail 58 are designed at the above-mentioned end opening position. The blocking hemisphere is a hemispherical structure with a plane as a whole. The blocking hemisphere movably blocks the cavity at the middle position of the internal fixing member 56 to prevent the skeleton oil seal 6 from injecting excessive grease. The guide rail 58 provides a movement limit for the blocking hemisphere 57. Through the above design, the blocking hemisphere 57 does not block the middle inner cavity of the internal fixing member 56 in the initial state of not filling oil, blocks the middle inner cavity of the internal fixing member 56 at the end of the oil filling state, and returns to the initial position, that is, the side of the internal fixing member 56 close to the opening position at the end of the oil filling state. It should be noted that the internal fixing member 56 can also be removed from the oil filling tool 5 or replaced with other components.
[0020] The rotating cover 59 is a round cap-shaped structure as a whole, and its inner side is rotatably connected to the outer side of the top of the base 54. The rotating cover 59 has a second oil injection cavity 53 and a placement cavity inside, and the internal fixing member 56 is placed in the above placement cavity. In order to improve the oil injection effect, the rotating cover 59 can be designed as an arc-shaped injection structure in the inner cavity that cooperates with the lip portion 61 of the skeleton oil seal 6, that is, the cavity structure that penetrates the outer wall of the rotating cover 59, and the specific number can be designed to be at least two or more.
[0021] The skeleton oil seal 6 in the figure is a hollow annular structure, which has a lip portion 61 and a spring portion 62; the lip portion 61 corresponds to the first oil filling chamber 52, and the spring portion 62 corresponds to the second oil filling chamber 53, so that oil is filled at two positions of the skeleton oil seal 6, thereby ensuring that the skeleton oil seal 6 is fully filled with oil to avoid omissions.
