[0002] Lubrication equipment is a specialized device used to lubricate assembled instruments (such as high-speed pulsers). The process requires manual tapping and turning to remove air bubbles from different locations on the instrument. Because the entire lubrication process is lengthy, it not only wastes a significant amount of manpower but also presents a risk of operator negligence due to its monotonous nature. Furthermore, existing lubrication equipment has many areas for improvement to make it more convenient and safer, and to achieve a degree of automation. Summary of the Invention

The reducer includes a first input end connected to the drive motor, a second input end connected to the connecting rod, and an output end coaxially connected to the spindle. The auxiliary drive assembly is configured to be activated when the drive motor cannot work normally. When the auxiliary drive assembly is activated, the handwheel drives the second input end connected to the connecting rod to rotate under the torque of an external force, thereby driving the reducer to rotate, and thus driving the spindle to rotate.

[0008] Furthermore, the clamping assembly includes a clamping ring connected to the free end of the spindle and an adapter detachably fixed to the inner circumferential wall of the clamping ring, the inner surface of the adapter being in contact with the outer surface of the equipment to be oiled.

[0016] Figure 2 is a schematic diagram of the external structure of an oil injection device according to an embodiment of the present invention. Detailed Implementation

[0017] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0018] Figures 1 and 2 illustrate the structure of an oiling device 100 according to an embodiment of the present invention. The oiling device 100 includes: a clamping assembly 1 for holding a device 200 to be oiled, an oiling assembly 2 for oiling the device 200, a driving assembly 3 for rotating the clamping assembly 1, and a striking assembly 4 for striking the clamping assembly 1. When the oiling assembly 2 oils the device 200 held on the clamping assembly 1, the driving assembly 3 drives the clamping assembly 1 to rotate while the striking assembly 4 strikes the clamping assembly 1.

[0019] In operation, the oiling device 100 of this embodiment can fix the device 200 to be oiled onto the clamping assembly 1. By designing and manufacturing different clamping assemblies 1, different devices 200 to be oiled can be fixed. During the oiling process, in order to remove air bubbles from the device 200, it is necessary to rotate and tap the device 200 to ensure that air bubbles in different locations are expelled as much as possible. The oiling device 100 of this embodiment drives the clamping assembly 1 to rotate via the driving assembly 3, thereby causing the device 200 to be oiled to rotate as well. According to different needs during the oiling process, the rotation angle, speed, and timing of the clamping assembly 1 can be specifically controlled. While the clamping assembly 1 is rotating the device 200 to be oiled, the tapping assembly 4 taps the device 200 to effectively improve the air bubble removal effect.

[0020] The oil injection device 100 of this embodiment of the invention, by adding a clamping component 1, a driving component 3 and a hammering component 4, enables the oil injection device 100 of this embodiment of the invention to have the functions of oil injection, flipping and hammering. The existing manual hammering and flipping actions are replaced by mechanical structures, which not only reduces the probability of human error and improves the effect and efficiency of oil injection, but also improves the convenience and safety of oil injection operation.

[0021] In the preferred embodiment shown in Figure 1, the drive assembly 3 may include a spindle support 31 fixed on a fixed foundation (the fixed foundation may be, for example, a housing 6, more specifically, a support beam within the housing 6), a spindle mounting plate 32 fixed on the spindle support 31, a spindle 33 rotatably mounted on the spindle mounting plate 32, the free end of the spindle 33 being connected to the clamping assembly 1, a reducer 34 coaxially connected to the drive end of the spindle 33, and a drive motor 35 connected to the reducer 34, the drive motor 35 being fixed on a motor base 36. The drive motor 35 drives the reducer 34 to rotate the spindle 33. By providing the reducer 34, the torque of the spindle 33 can be increased and the rotational speed of the spindle 33 can be reduced, thereby making the rotation of the spindle 33 more effortless and smoother.

[0022] Further, as shown in Figure 1, the oil injection assembly 2 may include a rotary hydraulic joint 21 coaxially connected to the end of the main shaft 33, a reducer 34 located between the rotary hydraulic joint 21 and the free end of the main shaft 33, an oil inlet pipe 22 connected between an external oil source and the rotary hydraulic joint 21, a transmission pipe 23 connected between the rotary hydraulic joint 21 and the oil injection device 200, and a return pipe 24 connected between the oil injection device 200 and the external oil source. The drive motor 35 drives the reducer 34 to rotate the rotary hydraulic joint 21, which in turn drives the main shaft 33 to rotate. The rotary hydraulic joint 21 is designed to connect the oil inlet pipe 22 and the transmission pipe 23 while ensuring that the transmission pipe 23 remains in its original state when the rotary hydraulic joint 21 rotates axially with the main shaft 33; that is, the transmission pipe 23 will not become entangled when the rotary hydraulic joint 21 rotates axially.

[0023] Furthermore, as shown in Figure 1, the oiling device 100 may also include an auxiliary drive assembly 5 for manually driving the main shaft 33 to rotate. The auxiliary drive assembly 5 includes a handwheel 51 and a connecting rod 52 connected to the handwheel 51. The connecting rod 52 is connected to a connecting rod seat 53. The reducer 34 includes a first input end connected to the drive motor 35 and a second input end connected to the connecting rod 52, as well as an output end coaxially connected to the main shaft 33. The first input end and the second input end are located on opposite sides of the reducer 34, and the output end is coaxial with the main shaft 33. Both the first input end and the second input end are perpendicular to the output end. The auxiliary drive assembly 5 is configured to be activated when the drive motor 35 cannot work normally. When the auxiliary drive assembly 5 is activated, the handwheel 51 drives the second input end connected to the connecting rod 52 to rotate under the torque of an external force, thereby driving the reducer 34 to rotate, and thus driving the main shaft 33 to rotate. When the oiling device 100 experiences a power outage or the drive motor 35 malfunctions, the oiling device 200 may be in any rotational position. Some of these positions may obstruct the maintenance of components within the oiling device 100. To facilitate internal maintenance by operators, the spindle 33 can be manually rotated as described above, thereby rotating the oiling device 200 on the clamping assembly 1 to a position that does not obstruct maintenance operations. Furthermore, manually rotating the spindle 33 can also be used to rotate the oiling device 200 to a detachable position for disassembly.

[0024] According to the present invention, as shown in FIG1, the clamping assembly 1 may include a clamping ring 11 connected to the free end of the main shaft 33 and an adapter 12 detachably fixed to the inner peripheral wall of the clamping ring 11. The inner surface of the adapter 12 is in contact with the outer surface of the oiling device 200. The adapter 12 may be made of plastic and is used to stably fix different oiling devices 200 within the clamping ring 11.

[0025] Preferably, the clamping ring 11 may include a ring portion having an opening and a door portion pivotally connected to the opening, the door portion being used for installing or removing the oiling device 200 when open relative to the opening, and the door portion being used for clamping and fixing the oiling device 200 when closed relative to the opening.

[0026] As shown in Figure 1, the striking assembly 4 may include a striking hammer and an air pump (not shown) connected to the striking hammer. The air pump is used to drive the striking hammer to strike the clamping assembly 1. By driving the striking hammer with an air pump, the striking of the hammer on the clamping assembly 1 during the oil injection process is more continuous and stable, thereby improving the removal effect of air bubbles in the oil injection equipment 200.

[0027] According to the present invention, as shown in FIG1, the oil injection equipment 100 may further include an industrial computer 7 for automatically controlling the oil injection process and collecting and recording oil injection data information. The industrial computer 7 can communicate with the production system via a network. By collecting and recording the oil injection data information and then processing it, it can be used to monitor the entire oil injection process in real time. Through the software in the industrial computer 7, the oil injection process of this equipment can be remotely controlled, freeing up manpower.

[0028] Specifically, the oil filling process can be divided into three steps: circulation filtration, vacuuming, and vacuum oil filling. In the first step, the oil filling data information may include a cleanliness index. During oil filling, the oil is filtered through a filter screen inside the oil filling machine (mainly to remove impurities from the equipment 200 to be oiled). Then, the content of particles of different sizes inside the oil is detected to obtain a cleanliness index. The industrial computer 7 can read this cleanliness index and determine whether it is lower than a preset cleanliness requirement value (the lower the cleanliness index, the better the oil quality). When it is lower than the preset cleanliness requirement value, a countdown of about 5 minutes will begin (because the cleanliness is detected at a certain point and cannot represent the entire oil filling circuit, the value may rebound; therefore, a countdown is set. When the cleanliness index is consistently lower than the cleanliness requirement value, it is determined that the cleanliness meets the standard). When the cleanliness rebounds, the countdown will be reset. After the countdown ends, the software in the industrial computer 7 will determine that the cleanliness meets the standard and then proceed to the next step. The second step involves activating the vacuum pump in the oiling machine to evacuate the entire oiling circuit (including the device 200 to be oiled). At this stage, the oiling data includes a vacuum level indicator. This process serves two purposes: firstly, it removes as much air as possible from the circuit, eliminating air bubbles; secondly, it verifies the airtightness of the device 200 (if the airtightness is poor, the vacuum level will not meet the requirements). Similar to the cleanliness indicator, a preset vacuum level requirement value can be set. If the detected vacuum level is lower than the preset requirement value and remains stable for 5 minutes, the software will determine that the vacuum level meets the standard and proceed to the next step. The third step, the control of the oil injection process, may include the control of oil injection volume, oil injection speed, hammer striking force, striking frequency, and spindle speed 33. The oil injection data information may include oil injection volume, oil injection speed, hammer striking force, striking frequency, spindle speed 33, pressure value of the pressure sensor used to detect the oil injection pressure in the oil injection device 200, and the vacuum degree of the oil before entering the oil injection device 200 (at this time, the vacuum degree refers to the minimum pressure value that the oil injection device 200 and the oil injection circuit can reach when all oil and air in the oil injection device 200 and the oil injection circuit are extracted; vacuum degree = external atmospheric pressure - negative pressure in the oil injection circuit).

[0029] Preferably, during the oil filling process, a safety threshold can be set for the values ​​of these oil filling data, and an alarm can be issued when the detected data value exceeds the safety threshold to remind the operator, thereby further improving safety performance. Preferably, since the oil content in the oil filling machine decreases during the filling process, the filling process cannot proceed when the oil level is too low. Therefore, a safety threshold can be set for the oil level in the oil filling machine, and an alarm can be issued when the level falls below the safety threshold to remind the operator to replenish the oil.

[0030] Furthermore, as shown in Figure 1, the oiling device 100 may also include a control plate 8, which may be equipped with multiple oiling modes for operators to select. By activating a specific oiling mode, the operator can achieve corresponding automatic oiling, automatic flipping, and tapping operations, simplifying the operator's work process.

[0031] In addition, permission settings can be added to the industrial computer 7 and control tablet 8 to prevent unauthorized personnel from making mistakes.

[0032] According to the present invention, as shown in Figures 1 and 2, the oil injection device 100 may include a housing 6, and a clamping assembly 1, an oil injection assembly 2, a driving assembly 3, and a striking assembly 4 are all disposed within the housing 6. An observation window 61 is provided on the upper part of the housing 6, and a transparent cover is provided on the observation window 61. This arrangement allows the operator to safely inspect the working condition of the components inside the housing 1, avoiding safety problems caused by excessive bulging of the bladder or oil splashing due to operational errors.

[0033] In addition, as shown in Figure 2, the housing 6 is also provided with a power interface 62 for supplying power to the oil injection device 100, an oil injection port 63 connected to the oil inlet pipe 22, an oil return port 64 connected to the oil return pipe 24, and an air pump interface 65 connected to the air pump.
