Description

Technical Field

[0001] This utility model relates to the field of transmission assembly technology, specifically to a quantitative refueling device. Background Technology

[0002] In the production and assembly process of transmissions, the lubrication process is one of the key steps to ensure the normal operation of the transmission. The precise control of the lubrication amount directly affects the transmission efficiency, service life, and operational stability of the transmission. Currently, the industry mostly uses a quantitative lubrication nozzle as the core tool for lubricating transmissions. To ensure the accuracy of the lubrication amount, after adding lubrication with the nozzle, the transmission must be weighed with an electronic scale for confirmation. If a deviation in the lubrication amount is found after weighing, additional lubrication or extraction is required, followed by weighing again until the lubrication amount meets the standard.

[0003] Using a fuel nozzle to lubricate the transmission not only adds processing steps, making the transmission assembly process more complicated, but also greatly increases the time for a single assembly, reducing overall production efficiency. Furthermore, multiple manual interventions increase the possibility of human error, further affecting the control of lubrication accuracy.

[0004] Therefore, a quantitative refueling device is urgently needed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a quantitative refueling device, comprising an oil tank 101 for storing oil, an upper oil pipe connector 102 for connecting to an oil pump, and a lower oil pipe connector 103 for connecting to a gearbox oil inlet; further comprising:

[0026] A control component, located inside the fuel tank 101, is used to control the maximum amount of fuel added inside the fuel tank 101.

[0027] A limiting component is provided between the oil tank 101 and the control component to limit the amount of oil supplied from the oil tank 101 to the transmission.

[0028] The driving component is located between the control component and the limiting component and is used to drive the limiting component.

[0029] And an observation device located on the front side of the fuel tank 101 for observing changes in the amount of fuel in the fuel tank 101;

[0030] It should be noted that during the process of using a quantitative filling device to fill the transmission, the control components, limit components, drive components, and observation components work together to achieve quantitative and visual filling of the transmission. This not only eliminates the tedious step of weighing the transmission after filling with an electronic scale, greatly reducing the assembly time per session and improving overall production efficiency, but also allows for flexible adjustment of different filling amounts according to the type of transmission, reducing the possibility of errors from manual intervention and improving the accuracy of filling control.

[0031] It is worth noting here that the technical solution of using an oil pump as the power component for medium transportation and a gearbox oil inlet as the refueling connection interface in this quantitative refueling device is known in the field of this technical application and will not be elaborated on here.

[0032] The control assembly includes a control rod 302 slidably connected to the oil tank 101. One end of the control rod 302 is fixedly connected to a float 301, which floats on the oil surface inside the oil tank 101. The other end of the control rod 302 is fixedly connected to a sensing disc 303. A T-shaped disc 304 is provided on the outer side of the sensing disc 303. The T-shaped disc 304 is concentrically arranged with the sensing disc 303, and the inner diameter of the sensing disc 303 is smaller than the inner diameter of the T-shaped disc 304. The T-shaped disc 304 is fixedly connected above the oil tank 101. A sensing assembly for sensing the sensing disc 303 is provided on the T-shaped disc 304. The sensing assembly includes a mounting hole 401 opened on the T-shaped disc 304, and a sensor 402 is fixedly installed on the mounting hole 401.

[0033] It should be noted that: the buoyancy of the float 301 causes the control rod 302 to move upward. The movement of the control rod 302 causes the sensing disc 303 to move upward. When the sensing disc 303 contacts the sensor 402, the oil pump stops refueling. At this time, the amount of oil stored in the oil tank 101 reaches its maximum value.

[0034] The limiting component includes a circular limiting plate 601 that is slidably sleeved on the control rod 302. The circular limiting plate 601 is concentrically arranged with the control rod 302. Multiple sets of connecting ears 602 are fixedly connected to the circular limiting plate 601. The multiple sets of connecting ears 602 are arranged in a ring array on the side of the circular limiting plate 601. The T-shaped cover 304 is provided with a scale line 603 for displaying the oil delivery volume.

[0035] It should be noted here that: the circular limit plate 601 restricts the movement of the sensing circular plate 303, thereby limiting the amount of oil added to the transmission. The circular limit plate 601 is connected to the drive assembly through the connecting ear 602, and the amount of oil added is displayed through the scale line 603, making the amount of oil added visible.

[0036] The drive assembly includes multiple sets of slots 504 vertically formed on the T-shaped cover 304. Each set of slots 504 corresponds to a connecting ear 602. The T-shaped cover 304 is rotatably connected to a rotating ring 501 via a thread. The rotating ring 501 has an annular groove 502. Multiple sets of T-shaped sliders 503 are slidably connected to the annular groove 502. One end of each set of T-shaped sliders 503 is fixedly connected to the connecting ear 602 and can slide up and down within the slot 504.

[0037] It should be noted that the drive ring 501, through the slot 504, causes the ring 501 to rotate and move up and down on the T-shaped cover 304. The movement of the ring 501 causes the circular limit plate 601 to move inside the T-shaped cover 304. When the upper surface of the ring 501 coincides with the upper limit of the scale line 603, the distance between the sensing circular plate 303 and the circular limit plate 601 is the shortest, representing the minimum oil filling amount of the transmission. When the upper surface of the ring 501 coincides with the lower limit of the scale line 603, the distance between the sensing circular plate 303 and the circular limit plate 601 is the farthest, representing the maximum oil filling amount of the transmission. Different oil filling amounts can be selected according to different types of transmissions to improve their adaptability.

[0038] The observation device is a transparent plate 2 fixedly installed on the front side of the fuel tank 101;

[0039] It should be noted here that the change in oil volume throughout the process can be seen through transparent plate 2.

[0040] Working principle: When using the quantitative refueling device to refuel the transmission, firstly, the oil pump is connected to the upper oil pipe connector 102 and the lower oil pipe connector 103 respectively. When it is necessary to refuel the oil tank 101, the oil pump is started and the oil is pumped into the oil tank 101 through the upper oil pipe connector 102. As the amount of oil in the oil tank 101 increases, the float ball 301 moves the control lever 302 upward under the action of the buoyancy of the oil. The movement of the control lever 302 moves the sensing disc 303 upward. When the sensing disc 303 contacts the sensor 402, the oil pump stops refueling. At this time, the amount of oil stored in the oil tank 101 reaches its maximum value.

[0041] When the transmission needs to be refilled, the oil pump draws oil from the lower oil pipe joint 103 and refills the transmission. The float 301 drives the sensing disc 303 to move downward. When the sensing disc 303 contacts the circular limit plate 601, the oil pump stops refilling. The amount of oil added is determined by the position of the circular limit plate 601. The operator can see the changes in the amount of oil throughout the process through the transparent plate 2, thus achieving quantitative refilling of the transmission.

[0042] During the adjustment of the position of the circular limit plate 601, the drive ring 501 is used to rotate and move up and down on the T-shaped cover 304 through the slot 504. The movement of the ring 501 causes the circular limit plate 601 to move inside the T-shaped cover 304. When the upper surface of the ring 501 coincides with the upper limit of the scale line 603, the distance between the sensing plate 303 and the circular limit plate 601 is the shortest, representing the minimum oil filling amount of the transmission. When the upper surface of the ring 501 coincides with the lower limit of the scale line 603, the distance between the sensing plate 303 and the circular limit plate 601 is the farthest, representing the maximum oil filling amount of the transmission. Different oil filling amounts can be selected according to different types of transmissions.

[0043] This refueling method not only eliminates the tedious step of weighing and confirming the gearbox after refueling with an electronic scale, greatly reducing the assembly time per session and improving overall production efficiency, but also allows for flexible adjustment of the distance between the sensing disc 303 and the circular limit disc 601 to regulate the amount of refueling according to the gearbox type, reducing the possibility of errors in manual intervention and improving the control of refueling accuracy.
