Description

[0001] The utility model relates to the field of tooling, and in particular to a motor assembly tooling. Background Art

[0002] The motor is an important part of automobiles such as new energy vehicles. It usually includes a motor housing, a stator and a rotor. During assembly, the stator is first installed in the motor housing, and then the rotor is matched with the stator. Since the stator is assembled when the motor housing is heated to 180°, that is, it is hot-fitted inside the motor housing, and the rotor has a strong magnetism, it needs to overcome the lateral attraction when assembled with the stator. Therefore, the assembly of the motor is basically impossible to achieve manually, and usually requires the help of assembly tools.

[0003] The existing stator and motor housing are assembled using one set of tooling, and the stator and rotor assembled with the motor housing are assembled using another set of tooling. That is, the entire motor assembly process requires two different sets of tooling, which not only has a high tooling cost, but also requires the motor housing and other components to be transported back and forth, resulting in low assembly efficiency.

[0030] like Figure 1-Figure 3 As shown, a motor assembly tool of an embodiment of the utility model includes a lifting and pressing mechanism 1, a shell positioning mechanism 2, a stator clamping movement mechanism 3 and a rotor clamping movement mechanism 4. The lifting and pressing mechanism 1 and the shell positioning mechanism 2 are arranged opposite to each other up and down, and the stator clamping movement mechanism 3 and the rotor clamping movement mechanism 4 are respectively arranged around the shell positioning mechanism 2. The stator clamping movement mechanism 3 is used to drive the stator to move to the top of the shell positioning mechanism 2, and the rotor clamping movement mechanism 4 is used to drive the rotor to move to the top of the shell positioning mechanism 2. The lifting and pressing mechanism 1 is used to press the stator into the motor shell 9 positioned by the shell positioning mechanism 2, and is used to press the rotor into the stator of the motor shell 9 positioned by the shell positioning mechanism 2.

[0031] Specifically, the lifting and pressing mechanism 1 is located above the shell positioning mechanism 2. The lifting and pressing mechanism 1 can be driven by any driving method such as a motor and a cylinder, and can be lifted and lowered in the vertical direction, that is, in the direction indicated by the Z axis. The lifting and pressing mechanism 1 can have multiple lifting strokes to meet the lifting needs of different heights. The shell positioning mechanism 2, the stator clamping motion mechanism 3 and the rotor clamping motion mechanism 4 can be used to fix the motor shell 9, the stator and the rotor respectively. In addition, the stator clamping motion mechanism 3 can also be used to drive the stator to move, and the rotor clamping motion mechanism 4 can also be used to drive the rotor to move. The positioning and clamping mechanisms used here can directly adopt existing technologies. The movement forms of the stator clamping motion mechanism 3 and the rotor clamping motion mechanism 4 can be sliding, rolling, etc.

[0032] In this embodiment, during assembly, the motor housing 9 is first placed on the housing positioning mechanism 2 and fixed, the stator is clamped on the stator clamping movement mechanism 3, and the rotor is clamped on the rotor clamping movement mechanism 4. Then, the stator clamping movement mechanism 3 moves to bring the stator to the top of the motor housing 9, the lifting and pressing mechanism 1 extends downward to press the stator into the motor housing 9, the lifting and pressing mechanism 1 retracts upward, and the stator clamping movement mechanism 3 moves away. Then, the rotor clamping movement mechanism 4 moves to bring the rotor to the top of the motor housing 9, and the lifting and pressing mechanism 1 extends downward again to press the rotor into the stator, thereby completing the assembly of the motor. Since the entire assembly process only requires one set of tooling, not only is the tooling cost lower, but also compared with the assembly method of first using one set of tooling to assemble the motor housing and the stator, and then using another set of tooling to assemble the stator and the rotor with the motor housing, the back and forth transportation of the motor housing is omitted, and the assembly efficiency is higher.

[0033] It should be noted that the stator clamping movement mechanism 3 and the rotor clamping movement mechanism 4 in this embodiment can be flexibly selected and replaced according to the type of the motor to be assembled.

[0034] like Figure 1-Figure 3 As shown, optionally, the motor assembly tooling also includes a stator and rotor lifting and supporting tooling 5, which is used to be set inside the motor housing 9 positioned by the housing positioning mechanism 2, and the lifting and pressing mechanism 1 is used to lower along with the stator and rotor lifting and supporting tooling 5 after the stator or rotor is pressed onto the stator and rotor lifting and supporting tooling 5.

[0035] Specifically, the stator and rotor lifting and supporting tooling 5 may include a motor and a lifting column. The motor drives the lifting column to rise and fall. The lifting column may be coaxially arranged with the motor housing 9 positioned by the housing positioning mechanism 2 to improve assembly accuracy.

[0036] In this embodiment, when it is necessary to heat-fit the stator into the motor housing 9 or to assemble the stator and rotor, the lifting column of the stator-rotor lifting and supporting fixture 5 is first raised. After the stator clamping movement mechanism 3 moves the stator to the top of the motor housing 9 or the rotor clamping movement mechanism 4 moves the rotor to the top of the motor housing 9, the lifting and pressing mechanism 1 extends downward to press the stator or the rotor against the lifting column of the stator-rotor lifting and supporting fixture 5. Thereafter, the lifting column descends, and the lifting and pressing mechanism 1 continues to extend downward. The stator or the rotor is stably clamped between the lifting and pressing mechanism 1 and the stator-rotor lifting and supporting fixture 5, and can be lowered under the drive of the stator-rotor lifting and supporting fixture 5 and the lifting and pressing mechanism 1 until the lifting column descends into place and the lifting and pressing mechanism 1 rises, thereby completing the heat-fitting of the stator in the motor housing 9 or the assembling of the stator and rotor.

[0037] By using the stator-rotor lifting and supporting tooling 5 in coordination with the lifting and pressing mechanism 1, the stator or rotor can be driven to descend stably, thereby improving the assembly accuracy of the motor.

[0038] like Figure 1 and Figure 5 As shown, optionally, the lifting and pressing mechanism 1 includes a lifting drive 11 and an inner support clamp 12, the lifting drive 11 is used to be detachably connected to the inner support clamp 12, and the inner support clamp 12 is used to grab the stator after the stator clamping movement mechanism 3 drives the stator to move to the top of the shell positioning mechanism 2.

[0039] Specifically, the lifting drive member 11 can be a motor or a cylinder, and the inner support fixture 12 is detachably connected to the lifting drive member 11, which can be easily disassembled and replaced. The inner support fixture 12 can shrink inward or expand outward to fix the cylindrical member.

[0040] In this embodiment, when the stator clamping movement mechanism 3 drives the stator to the top of the shell positioning mechanism 2, the inner support clamp 12 contracts and moves downward under the drive of the lifting drive 11 until the inner support clamp 12 is inserted into the interior of the stator. At this time, the inner support clamp 12 opens to fix the stator, and then the inner support clamp 12 can be driven by the lifting drive 11 to drive the stator to rise, so that the stator is separated from the stator clamping movement mechanism 3, and the stator clamping movement mechanism 3 is removed. After that, the lifting drive 11 drives the inner support clamp 12 downward again to drive the stator to descend and press the stator into the motor housing 9. After that, the inner support clamp 12 contracts to release the stator and rises under the drive of the lifting drive 11.

[0041] like Figure 5As shown, optionally, the internal support clamp 12 includes a fixed column 121 and a clamping claw 122. The fixed column 121 is provided with a plurality of clamping claws 122 along the circumferential direction. One end of the fixed column 121 is used to connect with the lifting drive member 11, and the other end of the fixed column 121 is provided with a first matching portion 123. The stator and rotor lifting and lifting tooling 5 is provided with a second matching portion 51 that is plugged and matched with the first matching portion 123.

[0042] Specifically, the fixing column 121 is arranged vertically, the upper end of the fixing column 121 is detachably connected to the lifting drive member 11, and a plurality of clamping claws 122 are arranged at intervals in the circumferential direction of the fixing column 121, and the stator can be fixed or loosened by opening or contracting the clamping claws 122, so that the structure is simple and easy to use. A guide column is arranged at the lower end of the fixing column 121 to form a first matching portion 123, and a guide groove is arranged on the stator-rotor lifting and lifting tooling 5 to form a second matching portion 51. Alternatively, a guide groove is arranged at the lower end of the fixing column 121 to form a first matching portion 123, and a guide column is arranged on the stator-rotor lifting and lifting tooling 5 to form a second matching portion 51. The guiding and positioning effect generated by the plug-in matching of the first matching portion 123 and the second matching portion 51 is utilized to realize the coaxial assembly of the stator and the motor housing 9.

[0043] In this embodiment, after the lifting drive 11 fixes the stator through the inner support fixture 12 and drives the stator to move upward so that the stator clamping movement mechanism 3 is removed, the lifting drive 11 drives the inner support fixture 12 to drive the stator to descend again, and after the first matching portion 123 at the lower end of the fixing column 121 is inserted into the second matching portion 51 on the stator-rotor lifting and lifting tooling 5, the lifting drive 11 moves downward together with the stator-rotor lifting and lifting tooling 5 until the stator-rotor lifting and lifting tooling 5 moves into place. During this shrink fitting process, if it is necessary to stop pressing down, the stator-rotor lifting and lifting tooling 5 and the lifting drive 11 can stop moving.

[0044] like Figure 1 and Figure 6 As shown, optionally, the lifting and pressing mechanism 1 further includes a pressure maintaining tool 13 . After the inner support fixture 12 is removed from the lifting drive member 11 , the pressure maintaining tool 13 is used to maintain the pressure of the stator pressed into the motor housing 9 under the drive of the lifting drive member 11 .

[0045] Specifically, the pressure-maintaining tool 13 matches the axial end surface shape of the stator, and the pressure-maintaining tool 13 is detachably connected to the lifting drive 11. After the stator is pressed into the motor housing 9 and the inner support fixture 12 is removed from the lifting drive 11, the pressure-maintaining tool 13 is connected to the lifting drive 11.

[0046] In this embodiment, the lifting drive 11 can apply a downward force to the axial end face of the stator through the pressure maintaining tool 13, so that good contact is formed between the stator and the motor housing 9, thereby ensuring the stability of the motor; an air cooler can be arranged around the motor assembly tooling, and the air cooler is turned on to cool the motor housing 9. Compared with natural cooling, the motor housing 9 can be cooled to the initial temperature faster, thereby completing the entire heat-shrink process.

[0047] In addition, in some cases, after the stator is pressed into the motor housing 9, the pressure holding tool 13 can be placed directly on the upper end surface of the stator without being connected to the lifting drive 11. At this time, the lifting drive 11 can also be used to drive the pressure holding tool 13 to be pressed against the stator.

[0048] Optionally, the lifting and pressing mechanism 1 also includes a pressing head (not shown in the figure). After the inner support clamp 12 is removed from the lifting drive member 11, the pressing head is used to press the rotor onto the stator-rotor lifting and lifting tooling 5 under the drive of the lifting drive member 11.

[0049] In this embodiment, the pressure head is detachably connected to the lifting drive member 11, which is convenient for assembly and disassembly. After the stator is heat-assembled, when the stator and rotor need to be assembled, the inner support fixture 12 or the pressure-maintaining tool 13 on the lifting drive member 11 is first removed, and then the pressure head is connected to the lifting drive member 11.

[0050] The rotor clamping motion mechanism 4 can be used only for clamping the rotor, or for clamping the rotor and the motor end cover. The rotor clamping motion mechanism 4 clamping the rotor and the motor end cover is used as an example for explanation: the rotor clamping motion mechanism 4 moves the rotor and the motor end cover to the top of the housing positioning mechanism 2, the stator-rotor lifting and lifting tooling 5 rises, and the lifting drive 11 drives the pressure head to descend to clamp the rotor between the two. After that, the rotor clamping motion mechanism 4 is removed, and the lifting drive 11 and the stator-rotor lifting and lifting tooling 5 drive the rotor to descend to install the rotor into the stator, and use the positioning pin to preliminarily fix the motor end cover and the motor housing. The stator-rotor lifting and lifting tooling 5 continues to descend until it reaches the preset position, the rotor is installed in place, the screws are tightened, and the lifting drive 11 drives the pressure head to rise to complete the stator-rotor assembly process. If the rotor clamping motion mechanism 4 is only used to clamp the rotor, then the lifting drive 11 and the stator-rotor lifting and lifting tooling 5 drive the rotor to descend, and the rotor is installed into the stator and installed in place.

[0051] In other embodiments, the pressing head is not connected to the lifting drive member 11. After the internal support clamp 12 or the pressure maintaining tool 13 on the lifting drive member 11 is removed and the rotor clamping movement mechanism 4 moves the rotor to the top of the shell positioning mechanism 2, the rotor is lifted by the stator-rotor lifting and lifting tooling 5, and then the pressing head is placed directly on the rotor. At this time, the lifting drive member 11 can also be used to drive the pressing head to press the rotor into the stator.

[0052] like Figure 1 and Figure 4 As shown, optionally, the motor assembly tool also includes a movable track 6, which is arranged on one side of the shell positioning mechanism 2, and the stator clamping movement mechanism 3 and the rotor clamping movement mechanism 4 are respectively arranged at both ends of the movable track 6, and are used to move toward or away from the shell positioning mechanism 2.

[0053] Specifically, the movable track 6 can be set behind the shell positioning mechanism 2 (in the negative direction of the X-axis) and extended along the direction of the Y-axis. The stator clamping movement mechanism 3 and the rotor clamping movement mechanism 4 are respectively movably set at both ends of the movable track 6 along the direction of the Y-axis.

[0054] In this embodiment, by setting a movable track 6, the stator clamping motion mechanism 3 and the rotor clamping motion mechanism 4 can move linearly along the movable track 6 on the left and right sides of the shell positioning mechanism 2 respectively, thereby realizing the movement guidance of the stator clamping motion mechanism 3 and the rotor clamping motion mechanism 4, improving the movement accuracy, so that the stator clamping motion mechanism 3 can move the stator accurately to the top of the motor housing 9 at the shell positioning mechanism 2, and the rotor clamping motion mechanism 4 can move the rotor accurately to the top of the motor housing 9 at the shell positioning mechanism 2.

[0055] like Figure 4 As shown, optionally, the motor assembly tool also includes a rotor fixing cylinder 7, which is located below the rotor clamping movement mechanism 4 and is used to drive the rotor to rise to a set height, and the set height is greater than or equal to the height of the motor housing 9 at the housing positioning mechanism 2. The rotor clamping movement mechanism 4 includes two oppositely arranged clamping plates 41, and the clamping height of the two clamping plates 41 is greater than or equal to the height of the motor housing 9 at the housing positioning mechanism 2. The two clamping plates 41 are used to clamp the rotor at the set height.

[0056] Specifically, the rotor fixing cylinder 7 can be lifted and lowered vertically. The two clamping plates 41 of the rotor clamping motion mechanism 4 are arc-shaped clamping plates, and can rotate relative to each other to achieve clamping or loosening, so as to meet the requirements of fixing and clamping rotors of different sizes. When the rotor clamping motion mechanism 4 is in the initial position, it corresponds to the rotor fixing cylinder 7 up and down. The rotor fixing cylinder 7 can drive the rotor to rise to a set height, and the set height is greater than or equal to the height of the motor housing 9 at the housing positioning mechanism 2, so as to ensure that the rotor clamping motion mechanism 4 can drive the rotor to move to the top of the motor housing 9 at the housing positioning mechanism 2 after clamping the rotor, so as to facilitate the subsequent assembly operation.

[0057] In this embodiment, after the two clamping plates 41 of the rotor clamping movement mechanism 4 are opened and the rotor is placed on the rotor fixing cylinder 7, the rotor fixing cylinder 7 is extended upward to drive the rotor to rise to a suitable position, and then the two clamping plates 41 clamp the rotor to complete the clamping of the rotor on the rotor clamping movement mechanism 4.

[0058] The rotor is clamped by two arc-shaped clamping plates. When the rotor clamping movement mechanism 4 brings the rotor to the top of the shell positioning mechanism 2 and is clamped by the lifting and pressing mechanism 1 and the stator-rotor lifting and lifting tooling 5, the rotor can be released by opening the two arc-shaped clamping plates, and then the rotor clamping movement mechanism 4 can be smoothly returned to the initial position by horizontal movement.

[0059] It should be noted that when the upper end surface of the stator-rotor lifting and supporting tooling 5 is flush with the motor housing 9 at the housing positioning mechanism 2, the rotor fixing cylinder 7 can drive the rotor to rise to the same height as the motor housing 9 or rise to above the motor housing 9, and then the rotor clamping movement mechanism 4 drives the rotor to move to directly above the motor housing 9 at the housing positioning mechanism 2; when the upper end surface of the stator-rotor lifting and supporting tooling 5 extends out of the motor housing 9 at the housing positioning mechanism 2, the rotor fixing cylinder 7 needs to drive the rotor to rise to above the motor housing 9 to ensure that the rotor clamping movement mechanism 4 can drive the rotor to move to directly above the motor housing 9 at the housing positioning mechanism 2.

[0060] like Figure 2 and Figure 4 As shown, optionally, the stator clamping movement mechanism 3 includes a stator support frame 31, and the support height of the stator support frame 31 is greater than or equal to the height of the motor housing 9 at the housing positioning mechanism 2;

[0061] And / or, the housing positioning mechanism 2 includes a plurality of pressure plates 21 arranged at intervals along the circumferential direction of its central axis, and the pressure plates 21 are respectively used to abut against the motor housing 9 to be positioned.

[0062] Specifically, the stator support frame 31 is used to support the stator. The setting height of the stator support frame 31 is greater than or equal to the height of the motor housing 9 at the housing positioning mechanism 2, ensuring that the stator clamping movement mechanism 3 can drive the stator to move to just above the motor housing 9 at the housing positioning mechanism 2, facilitating subsequent press-fitting.

[0063] The central axis of the housing positioning mechanism 2 is the axis of the motor housing 9, or the axis of the entire motor. The motor housing 9 can be fixed at multiple points by multiple pressing plates 21 arranged at intervals along the circumference, and the positioning method is relatively simple and the positioning accuracy is good.

[0064] like Figure 1As shown, optionally, the motor assembly tool further includes a workbench 8, and the housing positioning mechanism 2, the stator clamping movement mechanism 3 and the rotor clamping movement mechanism 4 are respectively arranged on the workbench 8.

[0065] Specifically, the workbench 8 provides a support platform for the shell positioning mechanism 2, the stator clamping movement mechanism 3, the rotor clamping movement mechanism 4 and the stator and rotor lifting and lifting tooling 5. The lifting and pressing mechanism 1 and the movable rail 6 can be fixed on the workbench 8 through brackets respectively, combining the various structures together for easy movement.

[0066] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
