Description

Technical Field

[0001] This invention relates to the field of assembly tool technology, and specifically to an assembly tool for a hard tube of a drive motor oil cooler water nozzle. Background Technology

[0002] As the speed and power density of motors in new energy vehicles increase, a large amount of heat is generated, posing a new challenge to motor heat dissipation. Most existing motors use water cooling technology, but water cooling is an indirect cooling method and can no longer fully meet the needs of high-speed, high-torque motors. Therefore, new energy vehicles are now starting to use oil-cooled motors.

[0003] The oil cooler is a crucial component in the oil-cooled motor cooling system. Its function is to provide circulating coolant to the drive motor, which carries away the internal heat. The oil cooler housing is equipped with rigid tube water nozzles, which connect to the vehicle's cooling pipes. During assembly, the rigid tubes need to be inserted into the water nozzles according to the design. However, in actual assembly, due to the lack of specialized positioning tools, operators often rely on experience and visual operation, using simple tools to hammer the rigid tubes into the oil cooler's water nozzles. This assembly method can cause the oil pipe angle to deviate from the design, and may even cause deformation of the water nozzles due to deviations in the direction of force applied during hammering. Summary of the Invention

[0004] To solve the above problems, the present invention provides a tool for assembling the rigid tube of the water nozzle of the drive motor oil cooler.

[0005] The technical solutions to the above technical problems are as follows:

[0006] A tool for assembling a rigid tube for a drive motor oil cooler water nozzle includes a first component and a second component, which are movably fitted together. The first component is a hollow cylinder with several graduations on one axial end face, which are aligned with the axis of the rigid tube. The other end of the first component has an extension base. The radial circumferential surface of the first component has a first notch. The second component passes through the first component and is fitted with the first component with a clearance. The axial end face of the second component has an alignment mark, and the radial circumferential surface of the second component also has a second notch. The alignment mark aligns with the graduations on the axial end face of the first component, and the second notch is fitted with the rigid tube with a clearance.

[0007] Furthermore, one end of the second component is exposed outside the first component, while the other end of the second component is located inside the first component.

[0008] Furthermore, several graduations on the axial end face of the first component are evenly divided graduations.

[0009] Furthermore, the second notch includes a left open end, a right open end, and a top open end, and each of the left open end, the right open end, and the top open end is provided with a rubber pad.

[0010] Furthermore, the rubber pads are respectively attached to the left opening end, the right opening end, and the top opening end of the second notch using adhesive.

[0011] The beneficial effects of this invention are as follows: This invention adjusts the angle of the rigid tube by rotating the second component, thereby aligning the centering mark on the second component with the scale on the first component. One of the scales on the first component is used to align the axis of the rigid tube. When the centering mark, the axis of the rigid tube, and one of the scales on the first component are on the same line, the rigid tube is installed according to the designed angle. This invention is not only simple to operate and saves time and effort, but also better avoids excessive positional deviation of the rigid tube and damage to the oil cooler nozzle caused by improper assembly during the assembly process.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] First, it should be noted that in order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be described more clearly and completely below in conjunction with the accompanying drawings. Obviously, the terms "upper", "lower", "axial", "radial" and other terms indicating orientation used in the description are merely a further and clearer description of the technical solution of the present invention based on the accompanying drawings, and cannot represent all embodiments of the present invention.

[0019] like Figures 1 to 4 As shown, a tool for assembling a rigid tube for a drive motor oil cooler includes a first component 1 and a second component 2. The first component 1 and the second component 2 are movably fitted together. The first component 1 is a hollow cylinder. A plurality of scales 1-1 are provided on one axial end face of the first component 1. The scales 1-1 are aligned with the axis of the rigid tube. An extension base 1-2 is provided at the other end of the first component 1. A first notch 1-3 is provided on the radial circumferential surface of the first component 1. The second component 2 passes through the first component 1 and is in clearance fit with the first component 1. An alignment mark 2-1 is provided on the axial end face of the second component 2. A second notch 2-2 is also provided on the radial circumferential surface of the second component 2. The alignment mark 2-1 is aligned with the scales 1-1 on the axial end face of the first component 1, and the second notch 2-2 is in clearance fit with the rigid tube.

[0020] Specifically, in this embodiment, when using this tool to assemble the rigid pipe, it is first necessary to pre-install the rigid pipe at the water inlet of the oil cooler, for example... Figure 1 As shown, first, rigid tube B is pre-installed at the water inlet of oil cooler A. Then, rigid tube B is placed in the second notch 2-2 of the second component 2, and the first component 1 is fitted onto the second component 2. The extension base 1-2 of the first component 1 contacts the end face of oil cooler A to stabilize the first component 1. According to the design requirements, a certain scale 1-1 on the axial end face of the first component 1 is aligned with the axis of rigid tube B (e.g., scale a1). Then, the second component 2 is rotated. Since rigid tube B is restricted by the second notch 2-2, it will also rotate when the second component 2 rotates. When the centering mark 2-1 of the second component 2 is aligned with a certain scale 1-1 on the axial end face of the first component 1 (e.g., scale a1), it indicates that rigid tube B has been rotated to the designed angle. Then, an external force is applied to the axial end of the second component 2. Under the restriction of the second notch 2-2, rigid tube B is forced and inserted into the water inlet of oil cooler A, thus completing the installation of rigid tube B according to the designed angle.

[0021] One end of the second component 2 is exposed outside the first component 1, and the other end of the second component 2 is located inside the first component 1.

[0022] Specifically, in this embodiment, since the upper end of the second component 2 needs to bear the axial external force, the upper end of the second component 2 must be exposed outside the first component 1. Conversely, since the second component 2 needs to be displaced downward after being subjected to force in order to apply a downward force to the rigid pipe B and thus complete the installation, the lower end of the second component 2 must be located inside the first component 1.

[0023] The first component 1 has several even-numbered divisions 1-1 on its axial end face.

[0024] The second notch 2-2 includes a left opening end 2-2a, a right opening end 2-2b, and a top opening end 2-2c. Rubber pads are provided on the left opening end 2-2a, the right opening end 2-2b, and the top opening end 2-2c of the second notch.

[0025] The rubber pads are respectively attached to the left opening end 2-2a, the right opening end 2-2b, and the top opening end 2-2c of the second notch using adhesive.

[0026] Specifically, in this embodiment, since the second component 2 needs to be rotated when assembling the rigid pipe, the left opening end 2-2a and the right opening end 2-2b of the second notch 2-2 will press against the surface of the rigid pipe. Therefore, in order to better protect the appearance of the rigid pipe, rubber pads (not shown in the attached figure) are glued to the left opening end 2-2a and the right opening end 2-2b of the second notch. The softness of the rubber pads helps to protect the rigid pipe. Similarly, since the rigid pipe needs to be inserted into the water nozzle by applying external force from the top after positioning, the top opening end 2-2c of the second notch of the second component 2 will also press against the rigid pipe when external force is applied to the axial end of the second component 2. Therefore, rubber pads are also glued to the top opening end 2-2c of the second notch.

[0027] Finally, it should be noted that the above-described embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit them, much less limit the scope of protection of the present invention; although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of protection of the claims.
