Description

Technical Field

[0001] The invention relates to the technical field of assembly tools, and in particular to an assembly tool for a water nozzle hard pipe of a drive motor oil cooler. Background Art

[0002] As the speed of new energy vehicle motors increases and the power density increases, the motors generate a lot of heat, which brings new challenges to motor heat dissipation. Most motors in existing technologies use water cooling technology, but water cooling technology is indirect cooling and can no longer fully meet the needs of high-speed, high-torque motors. Therefore, new energy vehicles are currently starting to use oil-cooled motors.

[0003] The oil cooler is an extremely important component in the cooling system of an oil-cooled motor. The function of the oil cooler is to provide circulating coolant for the drive motor, and the coolant takes away the internal heat of the drive motor. A hard tube water nozzle is provided on the shell of the oil cooler, and the hard tube is connected to the cooling pipe of the whole vehicle. During assembly, the hard tube needs to be plugged into the water nozzle according to the designed state. However, in the actual assembly process, due to the lack of special positioning tools, operators can often only rely on experience and visual operations, and use simple tools to knock the hard tube into the water nozzle of the oil cooler. This assembly method will cause the oil pipe angle to deviate from the designed state, and may even cause deformation of the water nozzle due to deviation in the force direction during knocking. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a driving motor oil cooler water nozzle hard pipe assembly tool.

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

[0006] A drive motor oil cooler water faucet hard pipe assembly tool comprises a first component and a second component, the first component and the second component are movably matched, the first component is in the shape of a hollow cylinder, a plurality of scales are provided on an axial end face of the first component, the scales are aligned with the axial center line of the hard pipe, an extension base is provided at the other end of the first component, a first notch is provided on the radial circumferential surface of the first component, the second component passes through the first component, and the second component and the first component are loosely matched, a centering mark is provided on the axial end face of the second component, and a second notch is also provided on the radial circumferential surface of the second component, the centering mark is matched with the scale on the axial end face of the first component, and the second notch is loosely matched with the hard pipe.

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

[0008] Furthermore, the plurality of scales on the axial end surface of the first component are even-numbered equally divided scales.

[0009] Furthermore, the second notch includes a left opening end of the second notch, a right opening end of the second notch, and a top opening end of the second notch, and rubber pads are provided on the left opening end of the second notch, the right opening end of the second notch, and the top opening end of the second notch.

[0010] Furthermore, the rubber pad is adhered to the left opening end of the second notch, the right opening end of the second notch, and the top opening end of the second notch by adhesive respectively.

[0011] The beneficial effects of the present invention are as follows: the present invention adjusts the angle of the hard tube by rotating the second component, so that the centering mark on the second component is aligned with the scale on the first component, and one of the scales on the first component is used to center the axial center line of the hard tube. When the centering mark, the axial center line of the hard tube and one of the scales on the first component are on the same line, the hard tube is installed according to the designed angle. The present invention is not only simple to operate, time-saving and labor-saving, but also can better avoid excessive position deviation and damage to the oil cooler faucet caused by improper assembly of the hard tube during the assembly process.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] First of all, it should be explained 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 in conjunction with the accompanying drawings. Obviously, the words "upper", "lower", "axial" and "radial" used in the description to indicate the orientation are only further and clearer descriptions of the technical solution of the present invention based on the accompanying drawings, and cannot represent all implementation plans of the present invention.

[0019] like Figures 1 to 4 As shown, a drive motor oil cooler water nozzle hard pipe assembly tool comprises a first component 1 and a second component 2, the first component 1 and the second component 2 are movably matched, the first component 1 is hollow cylindrical, a plurality of scales 1-1 are provided on an axial end face of the first component 1, the scales 1-1 are aligned with the axial center line of the hard pipe, and 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 the second component 2 and the first component 1 are clearance matched, a centering mark 2-1 is provided on the axial end face of the second component 2, and a second notch 2-2 is also provided on the radial circumferential surface of the second component 2, the centering mark 2-1 is matched with the scale 1-1 on the axial end face of the first component 1, and the second notch 2-2 is clearance matched with the hard pipe.

[0020] Specifically, in this embodiment, when the tool is used to assemble the hard pipe, the hard pipe needs to be pre-installed at the water nozzle of the oil cooler, for example Figure 1 As shown, the hard tube B is first pre-installed at the water nozzle of the oil cooler A, and then the hard tube B is placed in the second notch 2-2 of the second component 2, and the first component 1 is put on the second component 2, and the extension base 1-2 of the first component 1 contacts the end face of the oil cooler A to stabilize the first component 1. According to the design angle, a certain scale 1-1 on the axial end face of the first component 1 is aligned with the axial center line of the hard tube B (for example, the a1 scale), and then the second component 2 is rotated. Since the hard tube B is restricted by the second notch 2-2, when the second component 2 rotates, the hard tube B will also rotate with it. 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 (for example, the a1 scale), it means that the hard tube B has been rotated to the designed angle. Then, an external force is applied to the axial end of the second component 2, and the hard tube B is forced to be inserted into the water nozzle of the oil cooler A under the restriction of the second notch 2-2, so that the hard tube B is installed 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 move downward after being subjected to the force in order to apply a downward force to the hard tube B to complete the installation, the lower end of the second component 2 must be located inside the first component 1.

[0023] The plurality of scales 1 - 1 on the axial end surface of the first component 1 are even-numbered equally divided scales.

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

[0025] The rubber pad is respectively adhered to the left opening end 2-2a of the second notch, the right opening end 2-2b of the second notch, and the top opening end 2-2c of the second notch by adhesive.

[0026] Specifically, in this embodiment, since the second component 2 needs to be rotated when assembling the hard tube, the left open end 2-2a of the second notch and the right open end 2-2b of the second notch 2-2 will squeeze the surface of the hard tube. Therefore, in order to better protect the appearance of the hard tube, rubber pads (not shown in the accompanying drawings) are glued to the left open end 2-2a of the second notch and the right open end 2-2b of the second notch. The rubber pads are soft and thus play a role in protecting the hard tube. Similarly, since the hard tube needs to be inserted into the faucet by applying external force from the upper end after positioning, when external force is applied to the axial end of the second component 2, the top open end 2-2c of the second notch of the second component 2 will also squeeze the hard tube, so a rubber pad is also glued to the top open end 2-2c of the second notch.

[0027] Finally, it should be noted that the above-described implementation mode is only a preferred embodiment of the present invention to illustrate the technical solution of the present invention, and does not limit it, let alone limit the protection scope of the present invention; although the invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the protection scope of the claims.
