Description

Technical Field

[0001] The utility model relates to the technical field of gearbox oil pump testing, in particular to a gearbox oil pump quick-connect tooling. Background Art

[0002] The transmission oil pump is an important part of the transmission. It sucks the oil from the transmission oil pan and supplies it to various parts inside the transmission after pressurization, including the torque converter, gear mechanism, control system, etc., to achieve functions such as lubrication, cooling and hydraulic control. Therefore, it is very important to test the performance of the oil pump before use. In traditional testing, since different models of transmission oil pumps have different interface sizes and positions, in order to adapt to different interfaces, they are usually connected to the oil tank with a hose.

[0003] However, there are some shortcomings in the hose connection method. On the one hand, when the hose is connected to the oil pump interface, a clamp needs to be installed to tighten the connection. The connection process is complicated, which affects the test efficiency. On the other hand, in order to adapt to different types of transmission oil pumps, a longer hose needs to be reserved to ensure that the hose has sufficient range of motion for installation. Therefore, when the hose is used for connection, the length of the hose is long, which is easy to cause pressure (flow) loss, thereby affecting the accuracy of the test results. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide a gearbox oil pump quick-connect fixture to improve testing efficiency.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A gearbox oil pump quick-connect tooling comprises a mounting plate, a mounting seat for mounting the oil pump is provided on the mounting plate, a conversion structure is provided on the side of the mounting seat close to the oil pump joint, a docking structure connected to the oil tank is provided on the mounting plate, and the oil pump joint is connected to the docking structure after the joint size is converted by the conversion structure.

[0007] Compared with the principles and beneficial effects of existing technologies:

[0008] Before the test, the mounting seat and the conversion structure are installed as a whole to form a mounting assembly, and the docking structure is fixed on the mounting plate and connected to the oil tank. During the test, the oil pump is installed on the mounting assembly, and the oil pump connector can be converted to a size that matches the docking structure through the conversion structure, and then the mounting assembly is connected to the docking structure. The installation is simple and convenient, which can greatly shorten the installation time and help improve the test efficiency. By setting a conversion structure, this scheme can convert oil pump connectors of different models into a size that matches the docking structure, and then directly connect to the docking structure. Compared with the prior art using a hose connection method, this scheme not only saves installation time and improves test efficiency, but also the direct connection method can shorten the distance between the oil pump and the oil tank, thereby reducing the pressure loss caused by the length of the pipeline, which is conducive to improving the accuracy of the test results.

In this scheme, the connector of the oil pump is connected to the mounting hole. Since the interface size and position of different types of gearbox oil pumps are different, that is, the size and position of the mounting hole are different, by opening a conversion hole on one side of the mounting hole, the conversion hole can connect the mounting hole with the connecting hole. At this time, the mounting hole, the conversion hole, and the connecting hole are connected in sequence to form a channel for oil flow. The connecting hole is installed with a docking joint, and the docking joint here forms a new connector for the oil pump, that is, the purpose of converting the size of the docking joint is achieved.

The docking structure provided in this solution is fixed on the mounting plate, and the docking hole on the docking structure has a fixed size. Through the conversion structure, different types of oil pump joints can be converted to the same size and then connected to the docking hole, which is simple and convenient.

In this solution, since the oil tank is located at the lower side of the mounting plate, by setting the oil inlet interface at the bottom of the docking plate, when the oil is inlet, the oil in the oil tank can be directly connected from the bottom, and the flow path does not need to turn, which can shorten the distance from the oil inlet interface to the oil tank, thereby reducing the oil suction distance, reducing the pressure loss, and helping to improve the accuracy of the test results.

[0012] As a preferred embodiment of the utility model, steps are provided on both sides of the mounting seat, and two L-shaped pressing plates are provided on the mounting plate to match the steps on both sides.

The installation process is simple and convenient.

[0013] As a preferred embodiment of the utility model, the locking structure includes a locking groove opened on the upper side of the step, and a through locking hole is opened on the horizontal plate of the pressure plate corresponding to the locking groove, and the lower end of the bolt is abutted in the locking groove after passing through the locking hole.

The locking structure is simple, easy to operate, and conducive to improving installation efficiency.

[0014] As a preferred embodiment of the utility model, the inner spacing of the vertical plates of the two pressure plates is equal to the outer spacing of the two steps. In this solution, since the inner spacing of the vertical plates of the two pressure plates is equal to the outer spacing of the two steps, when the mounting seat slides horizontally to the lower side of the horizontal plate of the pressure plate, the two vertical plates can guide the mounting seat to facilitate sliding in. At the same time, after the mounting seat reaches the appropriate position, the two sides of the mounting seat can be limited to ensure the stability of the mounting seat.

[0026] See also Figure 1 and Figure 2 As shown, this embodiment discloses a gearbox oil pump quick-connect tool, including a mounting plate 1, on which a mounting seat 2 for mounting an oil pump 7 is provided. For details, see Figure 6 As shown, the mounting seat 2 is provided with a mounting cavity 24 for matching the oil pump 7, one side of the mounting cavity 24 is open, and the other side is provided with two mounting holes 21 for matching the oil pump connector 71, and the two connecting holes 41 are connected with the mounting cavity 24. After the oil pump 7 is installed into the mounting cavity 24 from the open side, the two connectors of the oil pump 7 are respectively inserted into the two mounting holes 21, wherein an annular sealing groove is provided on the outer side of the oil pump connector 71, and a sealing ring is installed in the sealing groove, and the sealing ring can ensure the sealing between the oil pump connector 71 and the mounting hole 21.

[0027] See also Figure 4 and Figure 5As shown, a conversion structure is provided on the side of the mounting seat 2 near the oil pump connector 71, and the oil pump connector 71 can be converted in size through the conversion structure. Specifically, the conversion structure includes a conversion hole 22 opened on the side of the mounting hole 21 away from the oil pump 7, and an adapter plate 4 is installed on the side of the mounting seat 2 near the conversion hole 22. The adapter plate 4 is tightly attached to the mounting seat 2, and a connecting hole 41 is opened on the adapter plate 4. The conversion hole 22 connects the mounting hole 21 and the connecting hole 41, and a docking joint 6 is installed on one end of the connecting hole 41 near the docking plate 5, wherein an annular sealing groove is also opened on the side wall of the mounting seat 2 and is located in the circumference of the conversion hole 22 and the connecting hole 41, and a sealing ring is installed in the sealing groove to ensure the sealing between the mounting seat 2 and the adapter plate 4. In the present solution, the connector of the oil pump 7 is connected to the mounting hole 21. Since the interface sizes and positions of different types of gearbox oil pumps 7 are different, that is, the sizes and positions of the mounting hole 21 are different, a conversion hole 22 is opened on one side of the mounting hole 21. The conversion hole 22 can connect the mounting hole 21 with the connecting hole 41. At this time, the mounting hole 21, the conversion hole 22, and the connecting hole 41 are connected in sequence to form a channel for oil flow. The connecting hole 41 is installed with a docking joint 6. The docking joint 6 here forms a new connector of the oil pump 7, which achieves the purpose of converting the size of the docking joint 6.

[0028] See also Figure 2 and Figure 3 As shown, the mounting plate 1 is provided with a docking structure connected to the oil tank, and the joint converted by the conversion structure is connected to the docking structure. Specifically, the docking structure includes a docking plate 5, and a docking hole 53 matching the docking joint 6 is opened on the docking plate 5, wherein an annular sealing groove is opened at both ends of the docking joint 6, and a sealing ring is installed in the sealing groove, and the sealing rings at both ends are used to ensure the sealing between the connection hole 41 and the docking joint 6, and the docking joint 6 and the docking hole 53 respectively. In this scheme, the docking plate 5 is fixed on the mounting plate 1. During the installation process, the docking joint 6 can be directly inserted into the docking hole 53, and the operation is simple and quick. The docking plate 5 is also provided with an oil outlet interface 51 connected to the oil return end of the oil tank and an oil inlet interface 52 connected to the oil outlet end of the oil tank, wherein the oil inlet interface 52 is located at the bottom of the docking plate 5, and a through hole 11 connected to the oil inlet interface 52 is opened at a position corresponding to the oil inlet interface 52 on the mounting plate 1. Since the oil tank is located at the lower side of the mounting plate 1, by setting the oil inlet interface 52 at the bottom of the docking plate 5, when the oil is introduced, the oil in the oil tank can be directly connected from the bottom, and the flow path does not need to turn, which can shorten the distance from the oil inlet interface 52 to the oil tank, thereby reducing the oil suction distance and reducing the pressure loss.

[0029] See also Figure 3As shown, steps 23 are integrally formed on both sides of the mounting seat 2, and two L-shaped pressing plates 3 are fixed on the mounting plate 1 to match the steps 23 on both sides. A locking structure for locking the mounting seat 2 is provided between the pressing plate 3 and the steps 23. Specifically, the locking structure includes a locking groove 231 provided on the upper side of the step 23, and a through locking hole 31 is provided on the horizontal plate of the pressing plate 3 corresponding to the locking groove 231. After the bolt is inserted from the locking hole 31, its lower end is abutted in the locking groove 231. When using this solution, the mounting seat 2 is placed on the mounting plate 1, and the steps 23 on both sides of the mounting seat 2 are horizontally slid into the lower side of the horizontal plate of the pressing plate 3. After the docking joint 6 is inserted into the docking hole 53, the bolt is screwed so that the bolt is inserted from the locking hole 31 and abutted against the upper end surface of the locking groove 231. The operation is convenient and helps to improve the installation efficiency. Among them, the inner side spacing of the vertical plates of the two pressing plates 3 is equal to the outer side spacing of the two steps 23. With this arrangement, when the mounting seat 2 slides horizontally to the lower side of the horizontal plate of the pressure plate 3, the two vertical plates can guide the mounting seat 2 to facilitate sliding in. At the same time, after the mounting seat 2 reaches the appropriate position, the two sides of the mounting seat 2 can be limited to ensure the stability of the mounting seat 2.

[0030] Specific implementation process:

[0031] Before the test, the mounting seat 2, the adapter plate 4, and the docking joint 6 are assembled as a whole to form a mounting assembly, and the docking plate 5 is fixed on the mounting plate 1 and connected to the oil tank. During the test, after the oil pump 7 is installed on the mounting assembly, the mounting assembly is placed on the mounting plate 1, and then the mounting assembly is pushed horizontally so that the steps 23 on both sides of the mounting seat 2 are located under the horizontal plate of the pressing plate 3. At this time, under the guidance of the vertical plate of the pressing plate 3, the docking joint 6 is inserted into the docking hole 53. After being inserted to the appropriate position, the bolt is screwed. After the bolt penetrates from the locking hole 31 and abuts against the upper end surface of the locking groove 231, the mounting seat 2 can be locked, and then the test can be started.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
