Description

Technical Field

[0001] The utility model belongs to the technical field of automobile gearbox production and detection technology. More specifically, the utility model relates to a gearbox circulating oil pumping and heating device. Background Art

[0002] During the off-line test of the gearbox assembly, in order to ensure the accuracy of the oil pressure, there are certain requirements for the gearbox oil temperature. The technical solution adopted by the existing technology is to heat the gearbox ATF oil through a refueling machine and then directly inject it into the gearbox.

[0003] Disadvantages of existing technology:

[0004] Due to the low temperature of the gearbox body, the oil temperature cannot meet the test requirements. The gearbox needs to be heated up through test conditions before testing, which lengthens the overall test cycle and affects the test efficiency.

[0005] The keywords "gearbox; test; oil; temperature" were used to search the existing published technical literature, and the following search results were obtained:

[0007] "A transmission temperature testing method and system, the method comprising: obtaining test data of a test vehicle under a plurality of preset driving conditions, wherein the preset driving conditions include driving parameter conditions and driving environment conditions of the test vehicle, and the test data include first temperature information of a transmission outer surface of the test vehicle, second temperature information of an engine outer surface, and third temperature information of transmission oil in the transmission; based on the test data, determining a target temperature relationship of the test vehicle, the target temperature relationship representing a mapping relationship between the temperature of the transmission oil and the temperature of the transmission outer surface and the temperature of the engine outer surface, and the target temperature relationship is used to determine the temperature information of the transmission oil of a vehicle in actual driving";

[0010] 2. Chinese patent document: "A method for controlling the temperature of hydraulic oil in a gearbox", patent (application) number: 202011552846.8, the technical solution recorded is:

[0011] “A method for controlling the temperature of hydraulic oil in a gearbox, comprising: when it is detected that the speed of a gearbox input shaft is greater than a first threshold and the load of a vehicle used by the gearbox is less than a second threshold, detecting the temperature of the hydraulic oil in a hydraulic circuit of a hydraulic system, and when the temperature of the hydraulic oil is greater than a third threshold, increasing the output torque of the gearbox, thereby increasing the pressure difference between a first position and a second position in the hydraulic circuit, until the pressure difference between the first position and the second position in the hydraulic circuit is not less than a fourth threshold, so that a flushing valve in the hydraulic circuit is opened, so that the hydraulic oil in the hydraulic circuit of the hydraulic system forms a circulation loop with the hydraulic oil in the oil replenishment pump of the hydraulic system”;

[0012] The technical effects recorded are:

[0013] "Lower the temperature of the hydraulic oil in the hydraulic circuit to avoid excessively high temperature of the hydraulic oil in the hydraulic circuit, which may affect the working performance of the hydraulic system."

[0038] like Figures 1 to 5 The structure of the utility model shown is a gearbox circulating oil pumping and heating device, which is applied to the gearbox assembly offline test process. The device is mainly composed of a roller line body, an electronic scale, a lifting slide, an oil injection docking mechanism and an oil pumping docking mechanism. Its detailed technical scheme and implementation method are specifically analyzed as follows:

[0039] In order to solve the problems existing in the prior art and overcome its defects, and to achieve the invention purpose of improving the efficiency of gearbox off-line testing, the technical solution adopted by the utility model is as follows: Figure 1 As shown:

[0040] The gearbox circulating oil filling, oil pumping and heating device of the utility model is provided with an oil filling docking mechanism 4 and an oil pumping docking mechanism 5; in the oil filling and oil pumping state during the test process, the oil filling docking mechanism 4 is docked with the oil filling port at the top of the gearbox; the oil pumping docking mechanism 5 is docked with the oil drain port at the bottom of the gearbox.

[0041] The utility model is aimed at the existing technology. During the off-line inspection of the gearbox assembly, after ATF oil (Automatic Transmission Fluid) is added to the gearbox, the oil temperature is low, which affects the test efficiency. Through the circulating pumping and oil pumping and heating device, high-temperature oil is injected from the top oil filling port of the gearbox, and oil is pumped from the bottom oil drain port of the gearbox at the same time. After adopting the circulating pumping and oil pumping and heating device, the effect of oil circulation and rapid heating is achieved, which greatly improves the test efficiency.

[0042] like Figure 2 Roller table body shown:

[0043] The oil filling, oil pumping and heating device is provided with a horizontal roller conveyor line body 1; the gearbox is placed on the roller conveyor line body 1 through a test tray and moved to the oil filling and oil pumping position during the test process.

[0044] Rollers 8 are arranged on both sides of the roller track body 1; the corresponding rollers 8 on both sides are connected by a connecting rod 9; the friction between the rollers 8 and the friction strips at the bottom of the test tray drives the test tray to move.

[0045] The pallet is driven forward by the friction between the roller 2 on the roller line 1 and the friction strip under the test pallet. A stopper is provided on the roller line 1. When the pallet is in place, the stopper is in a raised state. After the gearbox completes the cycle of oiling and oil pumping and heating, the PLC conveys the instruction that the workpiece processing is completed, the stopper falls, and the pallet is released.

[0046] The roller conveyor line body 1 is connected to the roller conveyor foot 7 through the bottom end of the roller conveyor support 6 and is installed on the ground.

[0047] The roller support 6 is the basis for supporting and installing the roller line body 1. The height and levelness of the roller line body 1 can be adjusted through the roller foot 7.

[0050] When the lifting slide 3 is raised to the highest position, the oil injection docking mechanism and the oil extraction docking mechanism 5 are docked with the gearbox.

[0051] like Figure 1 Electronic scale shown:

[0052] An electronic scale 2 is arranged below the lifting slide 3 .

[0053] The lifting slide 3 rises to the middle position, which is the weighing position of the electronic scale 2. After the lifting slide 3 falls to the weighing position, the electronic scale 2 records the first weighing value; after the gearbox completes the cycle of oil filling and oil pumping and heating, the electronic scale 2 records the second weighing value; subtract the two weights and divide them by the density of the ATF oil to get the oil replenishment amount.

[0054] like Figure 4 Oil injection docking mechanism shown:

[0055] The oil injection docking mechanism 4 is provided with an oil injection docking joint 21 and an oil injection displacement cylinder 19 ; the oil injection docking joint 21 is connected to the piston rod of the oil injection displacement cylinder 19 .

[0056] When the lifting slide 3 is raised to the highest position, the oil filling docking mechanism 4 inserts the oil filling docking joint 21 into the top filling port of the gearbox through the oil filling displacement cylinder 19 to perform oil filling.

[0057] The oil injection docking joint 21 is installed on the oil injection docking mechanism column 17 through the oil injection displacement cylinder 19.

[0058] The oil receiving box 20 is arranged on the oil filling joint 21. The oil receiving box 20 is a rectangular stainless steel box. The oil filling joint 21 returns to its original position after the oil filling joint 21 is completed. The oil filling box 20 is below the oil filling joint 21 and plays the role of receiving oil.

[0059] like Figure 5 The pumping docking mechanism shown:

[0060] The pumping docking mechanism 5 is provided with a pumping docking joint 16, a deceleration and lifting assembly 12 and a pumping displacement cylinder 15; the pumping docking joint 16 is connected to the piston rod of the pumping displacement cylinder 15.

[0061] When the lifting slide 3 is raised to the highest position, the two guide posts on the oil pumping docking mechanism 5 are inserted into the tray guide sleeve, and the tray oil pipe is used to connect the oil drain port at the bottom of the gearbox to pump oil.

[0062] The oil pumping docking mechanism 5 is also provided with a proximity switch 14 .

[0063] In summary, the beneficial effects of the utility model are:

[0064] By combining the lifting slide and the electronic scale, the weight of the gearbox before and after the oil filling and oil extraction can be compared, which can effectively ensure the accuracy of the oil filling amount inside the gearbox; the oil filling docking mechanism is used to add oil to the top oil filling port of the gearbox, and the oil extraction docking mechanism is used to extract oil from the bottom oil drain port of the gearbox, which solves the problems of low oil temperature and long cycle in the gearbox test, achieves the purpose of rapid and cyclic heating, and improves the test efficiency.

[0065] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
