Description

Technical Field

[0001] This application relates to the field of automated lubrication technology, and more particularly to an oil injection device. Background Technology

[0002] Currently, lubrication of industrial equipment is widely carried out manually, which leads to inaccurate oil dosage. Relying on manual operation easily results in insufficient or excessive oil levels: insufficient oil accelerates equipment wear and may even cause malfunctions, while excessive oil leads to oil waste, environmental pollution, and abnormal equipment operation. Furthermore, different equipment requires different grades of lubricating oil, but traditional grease guns are multi-purpose, leaving residues of different grades of lubricating oil inside the nozzle, easily causing cross-contamination and reducing lubrication performance, or even leading to abnormal equipment wear. Utility Model Content

[0003] This application addresses the shortcomings of the prior art by providing an oil injection device, comprising: a drive assembly, a piston assembly, a transmission rod, and an oil reservoir, wherein the oil reservoir is used to contain lubricant; the drive assembly is connected to the transmission rod, and the drive assembly is capable of driving the transmission rod to rotate clockwise along the axial direction of the transmission rod, and the drive assembly is also capable of driving the transmission rod to rotate counterclockwise along the axial direction of the transmission rod; the piston assembly is connected to the transmission rod, and the piston assembly is capable of reciprocating with the clockwise and counterclockwise rotation of the transmission rod, wherein the reciprocating movement of the piston assembly can discharge lubricant from the oil reservoir and draw external lubricant into the oil reservoir.

[0004] Furthermore, the piston assembly includes a sensor for monitoring the remaining amount of lubricant in the oil reservoir.

[0005] Furthermore, the oil injection device also includes a control component, which is used to control the operating state of the drive component.

[0006] Furthermore, the control component is configured to: measure the number of rotations of the transmission rod along the axial direction; and calculate the remaining amount of lubricant in the oil reservoir based on the number of rotations.

[0007] Furthermore, the oil injection device also includes a coupling for connecting the drive assembly and the transmission rod.

[0008] Furthermore, the oil injection device also includes a power supply component, which supplies power to the drive component and the control component.

[0009] Furthermore, the oil injection device also includes a sealing assembly for sealing the oil injection device, the sealing assembly including a sealing ring and a threaded cap.

[0010] Furthermore, the threaded cap is correspondingly disposed to at least a portion of the drive assembly; at least a portion of the oil reservoir is provided with threads, and the drive assembly and the oil reservoir are detachably connected via the threaded cap and the threads.

[0011] Furthermore, the oil injection device also includes a plug for inputting control signals into the control component.

[0012] Furthermore, an oil inlet is provided at the end of the oil storage cavity away from the drive assembly, wherein the oil inlet is threaded.

[0013] Furthermore, the oil injection device also includes an oil injection head, which includes one of a straight oil injection head and a curved oil injection head, wherein the straight oil injection head and the curved oil injection head are respectively threaded to the oil injection port.

[0014] Furthermore, when the transmission rod rotates clockwise along the axial direction, the piston assembly moves toward the oil inlet, thereby discharging the lubricant from the oil reservoir.

[0015] The embodiments described in this application have the following beneficial effects:

[0016] The oil filling device provided in this application includes: a drive assembly, a piston assembly, a transmission rod, and an oil reservoir. The drive assembly is connected to the transmission rod and can drive the transmission rod to rotate clockwise along the axial direction of the transmission rod, and the drive assembly can also drive the transmission rod to rotate counterclockwise along the axial direction of the transmission rod. The piston assembly is connected to the transmission rod and can reciprocate with the clockwise and counterclockwise rotation of the transmission rod, thereby discharging the lubricant in the oil reservoir and drawing external lubricant into the oil reservoir. This application achieves precise control of the oil filling amount (or the amount of oil drawn into the oil reservoir) through the coordinated operation of the drive assembly, piston assembly, transmission rod, and oil reservoir. Furthermore, the oil reservoir of this application is replaceable; different oil reservoirs contain different grades of lubricant.

[0021] The technical solutions in this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Lubrication equipment is used to add lubricant to bearings, gears, chains, and other components of mechanical equipment to reduce friction and wear, and extend the service life of the equipment. Currently, the common lubrication method is manual operation of a grease gun. However, relying on manual control makes it difficult to precisely control the amount of lubricant injected, affecting the lubrication effect. Therefore, this application provides an automatic lubrication device.

[0023] The following is combined Figure 1 as well as Figure 2 The oil injection equipment 100 of this application will be described in detail. Figure 1 A structural diagram of an oil injection device according to an embodiment of this application is shown. Figure 2 A top view of an oil injection device according to an embodiment of this application is shown. (Refer to...) Figure 1The oil injection device 100 provided in this application includes: a drive assembly 101, a piston assembly 102, a transmission rod 103, and an oil reservoir 104, wherein the oil reservoir 104 is used to contain lubricant; the drive assembly 101 is connected to the transmission rod 103, and the drive assembly 101 can drive the transmission rod 103 to rotate clockwise along the axial direction of the transmission rod 103, and the drive assembly 101 can drive the transmission rod 103 to rotate counterclockwise along the axial direction of the transmission rod 103; the piston assembly 102 is connected to the transmission rod 103, and the piston assembly 102 can reciprocate with the clockwise and counterclockwise rotation of the transmission rod 103, wherein the reciprocating movement of the piston assembly 102 can discharge the lubricant in the oil reservoir 104 and draw external lubricant into the oil reservoir 104.

[0024] The drive assembly 101 is the core power source of the oil injection device 100. The drive assembly 101 is tightly connected to the transmission rod 103, thereby transmitting power to the transmission rod 103. The drive assembly 101 can drive the transmission rod 103 to rotate clockwise or counterclockwise along its axial direction. When clockwise rotation is required, the drive assembly 101 rotates in a specific direction, transmitting power to the transmission rod 103, causing it to rotate clockwise. When counterclockwise rotation is required, the drive assembly 101 changes its rotation direction, causing the transmission rod 103 to rotate counterclockwise. The drive assembly 101 can, for example, use a quiet motor, which not only provides stable and reliable power but also reduces vibration and noise.

[0025] The piston assembly 102 is connected to the transmission rod 103. When the transmission rod 103 rotates, the piston assembly 102 can reciprocate under the drive of the transmission rod 103. The piston assembly 102 moves in the forward direction along the transmission rod 103 in the oil reservoir 104 (that is, the transmission rod 103 rotates clockwise in the axial direction), and the piston assembly 102 can discharge the lubricant in the oil reservoir 104. The piston assembly 102 moves in the reverse direction along the transmission rod 103 in the oil reservoir 104 (that is, the transmission rod 103 rotates counterclockwise in the axial direction), and can draw external lubricant into the oil reservoir 104.

[0026] Furthermore, the piston assembly 102 may include a sensor 1021 for monitoring the remaining amount of lubricant in the oil reservoir 104.

[0027] Reference Figure 2The piston assembly 102 may include a sensor 1021, which can monitor the remaining amount of lubricant in the oil reservoir 104 in real time. The sensor 1021 can be directly embedded in the piston assembly 102 or installed at the connection between the piston assembly 102 and the oil reservoir 104. The remaining amount of lubricant is obtained by monitoring the position of the piston assembly 102 or the pressure in the oil reservoir 104. It is understood that the sensor 1021 can be a displacement sensor, a pressure sensor, or other types of sensors. This application does not limit the type of sensor, as long as it can implement the technical principles described in this application.

[0028] The oil reservoir 104 is used to hold lubricant and can provide sufficient lubricant for the oiling device 100. At the same time, the oil reservoir 104 is detachably connected to the drive assembly 101, allowing users to quickly and conveniently replace the oil reservoir 104 when using different types of lubricants. This avoids mixing different types of lubricants in the same reservoir, effectively preventing cross-contamination and ensuring the purity of the inside of the oil reservoir 104.

[0029] The drive assembly 101 can drive the transmission rod 103 to rotate clockwise or counterclockwise along the axial direction. The rotation of the transmission rod 103 in turn drives the piston assembly 102 to reciprocate within the oil reservoir 104. The piston assembly 102 moves forward along the transmission rod 103 within the oil reservoir 104 (i.e., the transmission rod 103 rotates clockwise along the axial direction), which can discharge the lubricant from the oil reservoir 104. The piston assembly 102 moves backward along the transmission rod 103 within the oil reservoir 104 (i.e., the transmission rod 103 rotates counterclockwise along the axial direction), which can draw external lubricant into the oil reservoir 104.

[0030] It is understood that the above description of the drive assembly 101, piston assembly 102, transmission rod 103 and oil reservoir 104 is merely exemplary. Those skilled in the art can configure the drive assembly 101, piston assembly 102, transmission rod 103 and oil reservoir 104 according to actual needs, as long as the technical principles of this application can be realized.

[0031] Furthermore, an oil inlet is provided at one end of the oil storage cavity 104 away from the drive assembly 101, wherein the oil inlet is threaded.

[0032] like Figure 1 As shown, the oil reservoir 104 may have an oil inlet at one end away from the drive assembly 101, and the oil inlet is threaded, which allows the oil inlet to be tightly connected to an oiling component (such as an oiling head or oiling nozzle). For example, the oil inlet has an external thread, while the oiling component has a corresponding internal thread, allowing the oiling component to be screwed onto the oil inlet to form a sealed connection.

[0033] When lubrication is required, align the lubrication component (such as a lubrication head or nozzle) with the lubrication port and rotate it clockwise to ensure a tight connection between the internal thread of the lubrication component and the external thread of the lubrication port. This ensures that the lubrication component will not loosen or fall off during the lubrication process. Furthermore, the threaded connection between the lubrication port and the lubrication component provides excellent sealing, preventing lubricant leakage.

[0034] In this application, the oil injection device 100 may further include: an oil injection head (not shown in the figure), the oil injection head including one of a straight oil injection head and a curved oil injection head, wherein the straight oil injection head and the curved oil injection head are respectively threaded to the oil injection port.

[0035] For example, the oil inlet can be connected to a straight oil inlet or a curved oil inlet, and both the straight oil inlet and the curved oil inlet are provided with threads. The straight oil inlet (or the curved oil inlet) can be tightly connected to the oil inlet at the end of the oil reservoir 104 away from the drive assembly 101 through the threads, thereby preventing the leakage of lubricant during the oil filling process.

[0036] The curved injection nozzle can be at a certain bending angle (e.g., 90 degrees or 45 degrees), making it suitable for corners or areas difficult to reach with a straight injection nozzle. Furthermore, in situations where space is limited, the curved injection nozzle can bypass obstacles and inject lubricant directly into the target location.

[0037] In this application, the oil injection device 100 may further include a control component 105, which is used to control the operating state of the drive component 101.

[0038] Specifically, the control component 105 can precisely control the operating state of the drive component 101 (e.g., starting or stopping the drive component), thereby ensuring that the piston assembly 102 reciprocates along the transmission rod 103 within the oil reservoir 104. The control component 105 can control the rotational speed of the drive component 101. By changing the rotational speed of the drive component 101, the rotational speed of the transmission rod 103 can be adjusted, thereby controlling the reciprocating speed of the piston assembly 102, and thus precisely controlling the amount of oil injected by the oil injection device 100.

[0039] The control component 105 can be configured to: measure the number of rotations of the transmission rod 103 along the axial direction; and calculate the remaining amount of lubricant in the oil reservoir 104 based on the number of rotations.

[0040] For example, the control component 105 can calculate the remaining amount of lubricant in the oil reservoir 104 by measuring the number of rotations of the transmission rod 103 in the axial direction. Specifically, the operating time of the motor can be measured, and the number of rotations of the transmission rod 103 can be calculated based on the relationship between the motor speed and the operating time. The distance moved by the piston assembly 102 can be calculated based on the number of rotations of the transmission rod 103, and then the remaining amount of lubricant in the oil reservoir 104 can be calculated.

[0041] Furthermore, the number of rotations of the transmission rod 103 along the axial direction can also be transmitted to the control component 105 based on the number of rotations of the rotor in the motor. Specifically, there is a close mechanical connection between the transmission rod 103 and the rotor of the motor. When the motor starts, the rotor rotates and transmits force to the transmission rod 103 through a transmission mechanism (such as a gear, belt, or coupling), thereby driving the transmission rod 103 to rotate along the axial direction. The number of rotations of the transmission rod 103 is a fixed ratio to the number of rotations of the motor rotor, so the control component 105 can calculate the number of rotations of the transmission rod 103 based on the number of rotations of the rotor.

[0042] It is understood that the above description of the control component 105 is merely exemplary, and those skilled in the art can configure the control component 105 according to actual needs, as long as it can achieve the technical principles of this application.

[0043] In this application, the oil injection device 100 may further include a coupling 106, which is used to connect the drive assembly 101 and the transmission rod 103.

[0044] Specifically, the power generated by the drive assembly 101 is transmitted to the transmission rod 103 through the coupling 106, enabling the transmission rod 103 to rotate at a predetermined speed and direction. The coupling 106 can compensate for axial, radial, or angular deviations between the drive assembly 101 and the transmission rod 103, ensuring the smooth operation of the transmission rod 103.

[0045] In this application, the oil injection device 100 may further include a power supply component 107, which is used to supply power to the drive component 101 and the control component 105.

[0046] Specifically, the power supply component 107 is a key component for the stable operation of the oiling equipment 100, providing the necessary power to the drive component 101 and the control component 105. The power supply component 107 can be, for example, a built-in rechargeable battery pack or directly connected to an external power source. If it is a rechargeable battery pack, the power supply component 107 can provide continuous and stable power during the operation of the oiling equipment 100. If it is an external power source, it can continuously supply power to the oiling equipment 100.

[0047] In this application, the oil injection device 100 may further include a sealing assembly 108, which is used to seal the oil injection device 100, and the sealing assembly 108 includes a sealing ring and a threaded cap.

[0048] Specifically, the sealing assembly 108 enables the oiling device 100 to maintain good sealing performance under various operating conditions. The sealing assembly 108 may include a sealing ring and a threaded cap. For example, the sealing ring may be made of an oil-resistant, wear-resistant, and elastic material, allowing it to fit tightly to the location requiring sealing, such as the connection between the drive assembly 101 and the oil reservoir 104, or the connection between the piston assembly 102 and the transmission rod 103. Furthermore, the sealing ring can undergo slight deformation under certain pressure, effectively preventing lubricant leakage. The threaded cap is correspondingly disposed to at least a portion of the drive assembly 101, further enhancing the sealing effect of the oiling device 100.

[0049] Furthermore, the threaded cap is correspondingly disposed to at least a portion of the drive assembly 101; at least a portion of the oil storage cavity 104 is provided with threads, and the drive assembly 101 and the oil storage cavity 104 are detachably connected through the threaded cap and the threads.

[0050] For example, a threaded cap is disposed corresponding to at least a portion of the drive assembly 101, and at least a portion of the oil reservoir 104 is provided with threads. The threads on the oil reservoir 104 correspond to the threads on the threaded cap, enabling a detachable connection between the drive assembly 101 and the oil reservoir 104. Specifically, the inner or outer wall of the threaded cap is provided with threads. When it is necessary to connect the oil reservoir 104 to the drive assembly 101, the threaded cap is aligned with the threaded portion of the oil reservoir 104, and then the threaded cap is rotated to tightly engage the threads of the drive assembly 101 and the oil reservoir 104. Conversely, when it is necessary to disassemble the oil reservoir 104 from the drive assembly 101, the threaded cap is rotated in the opposite direction to separate the drive assembly 101 from the oil reservoir 104.

[0051] In this application, the oil injection device 100 may further include a plug 109 for inputting control signals into the control component 105.

[0052] Specifically, plug 109 is an important interface for connecting external control signals to control component 105, ensuring the stability and reliability of signal transmission. Furthermore, plug 109 supports multiple signal types, including analog and digital signals such as RS-232 and RS-485, enabling seamless connection between the oil filling device 100 and external control systems for data exchange.

[0053] For example, when a user needs to remotely control or adjust the parameters of the oiling device 100, the control signal is input to the control component 105 through the plug 109. For example, the user can send instructions through the host computer software to set parameters such as the oiling time interval, oiling volume, and operating mode. These instructions are transmitted to the control component 105 in the form of electrical signals through the plug 109, thereby controlling the operating state of the drive component 101 and achieving precise oiling of the oiling device 100.

[0054] The oil filling device provided in this application includes: a drive assembly, a piston assembly, a transmission rod, and an oil reservoir. The drive assembly is connected to the transmission rod and can drive the transmission rod to rotate clockwise along the axial direction of the transmission rod, and the drive assembly can also drive the transmission rod to rotate counterclockwise along the axial direction of the transmission rod. The piston assembly is connected to the transmission rod and can reciprocate with the clockwise and counterclockwise rotation of the transmission rod, thereby discharging the lubricant in the oil reservoir and drawing external lubricant into the oil reservoir. This application achieves precise control of the oil filling amount (or the amount of oil drawn into the oil reservoir) through the coordinated work of the drive assembly, piston assembly, transmission rod, and oil reservoir. Furthermore, the oil reservoir of this application is replaceable; different oil reservoirs contain different grades of lubricant. When adding lubricant to different equipment, only the corresponding oil reservoir needs to be replaced, thereby avoiding cross-contamination of the oil reservoir caused by mixing lubricants.
