Description

Technical Field

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

[0002] At present, for example, motors used in reducers for new energy vehicles are increasingly widely used. The motors have rectangular housings and matching end covers. In the process of assembling the end covers to the housing, the requirements for precise positioning need to be met. Therefore, the assembly tooling needs to consider the fixation of the motor, the anti-collision of the motor, and the fixation of the tooling. Specifically, the assembly tooling is required to meet at least the following requirements: 1: Since the rectangular housing is designed with three assembly holes, three-point positioning is required for precise matching; 2: The motor housing needs to be prevented from being damaged during the assembly process; 3. Ensure that the assembly flatness of the housing and the tooling is highly consistent to ensure a smooth closing process. However, the existing assembly tooling has the following deficiencies corresponding to the three requirements: 1: Using less than three points for positioning cannot ensure the flatness of the motor during assembly, so that the assembly accuracy cannot be guaranteed even if it needs to be repeatedly adjusted, resulting in the inability to completely fix the end cover and the casing. Therefore, there are the disadvantages of poor assembly accuracy and complicated operation; 2: When the casing is in the tooling and the end cover is not assembled, there is an inevitable situation that the casing structure is damaged, resulting in certain losses; 3: It is impossible to ensure that the assembly flatness consistency of the casing and the tooling is high, resulting in a difficult cover closing process. When the end cover is assembled, if it is not handled properly, it is easy to damage the sealing glue of the motor and thus lead to an increase in the defective rate.

[0003] Therefore, there is an urgent need to provide a motor assembly tool with high assembly accuracy and simplified operation. Utility Model Content

[0027] refer to Figures 1 to 3 As an object of the present utility model, an embodiment of a motor assembly tool is provided, wherein the motor assembly tool comprises a bottom plate 1, a base 2 and a plurality of positioning columns 3 of greater than or equal to 3, wherein the base 2 is fixed on the bottom plate 1 and is used to support and position the housing 41 of the motor 4, wherein the plurality of positioning columns 3 are fixed on the bottom plate 1 and are located at the outer periphery of the base 2, wherein a plurality of positioning holes may be provided on the base 2, so that the plurality of positioning columns 3 may be respectively fixed to the respective positioning holes by fixing bolts and other fixing members. The plurality of positioning columns 3 are used to be plugged and matched with the covers corresponding to the housing 41 and the end cover 42 of the motor 4 so as to align the plurality of first connection parts of the end cover 42 with the plurality of second connection parts of the housing 41 to form a plurality of connection part pairs, so that the end cover 42 and the housing 41 can be fixed by connecting the plurality of connection parts to the plurality of connection part pairs respectively. Therefore, the use of multiple positioning columns 3 can provide at least three-point positioning for the housing 41, thereby ensuring the flatness of the motor 4 during assembly, so that each connecting part can accurately fix the end cover 42 to the housing 41, thereby achieving the technical effect of high assembly accuracy and simplified operation.

[0028] Please refer to Figure 3Specifically, the positioning column 3 includes a connected plug-in column 31 and a support column 32, the support column 32 is fixed to the bottom plate 1, the outer diameter of the plug-in column 31 is smaller than the outer diameter of the support column 32, the plug-in column 31 and the support column 32 can be respectively set as a first cylinder and a second cylinder, and the diameter of the second cylinder is smaller than the diameter of the first cylinder, the plug-in column 31 is used to be simultaneously plugged into a shell through hole 411 of the housing 41 and a positioning cover hole 421 of the end cover 42, and the top plane where the support column 32 and the plug-in column 31 meet supports the end cover 42. Therefore, the plug-in column 31 and the support column 32 of each positioning column 3 play a role in positioning and supporting the housing 41 and a role in positioning the end cover 42, so as to ensure that the assembly plane consistency of the housing 41 and the tooling is high, the closing process is simple, and when the end cover 42 is assembled, there will be no adverse situation that the sealing glue of the motor 4 is damaged, thereby causing an increase in the unqualified rate. In particular, when the top planes of the plurality of positioning posts 3 are located on the same plane, the supported plane of the end cover 42 can be well positioned flat, thereby further ensuring that the assembly flatness consistency between the housing 41 and the tooling is high.

[0029] Please refer to Figure 4 and Figure 5 Specifically, the housing 41 includes a protruding housing 412, an intermediate housing 413 and an end housing 414 connected to each other. The protruding housing 412 and the intermediate housing 413 are both cylindrical in shape. The diameter of the protruding housing 412 is smaller than the diameter of the intermediate housing 413. The base 2 is a torus with a hollow portion 21. The shell end face of the intermediate housing 413 is supported on the seat top face of the base 2. The hollow portion 21 positions the protruding housing 412 therein. Therefore, in the direction perpendicular to the bottom plate 1, the intermediate housing 413 and the end housing 414 of the housing 41 are accurately positioned, and the protruding housing 412 can be positioned simultaneously in two directions perpendicular to and parallel to the bottom plate 1, so that the housing 41 is accurately fixed on the bottom plate 1, ensuring the accurate assembly of the end cover 42 and the housing 41.

[0030] Please refer to Figure 3 and Figure 5Specifically, the end cover 42 is configured to include a rectangular cover body 422 and a plurality of cover bosses 423 protruding from the side of the cover body 422, the end shell 414 is provided with a relatively protruding shell boss 415, a positioning cover hole 421 is provided in the cover boss 423, and a shell through hole 411 is provided in the shell boss 415. The end shell 414 protrudes relative to the outer periphery of the intermediate shell 413 and is configured to have a shell cavity with a rectangular body shape, and is used to cover the shell cavity in the cover body 422. The number of cover bosses 423, shell bosses 415 and positioning columns 3 are all equal. A first connecting hole 424, such as a threaded hole, is provided at each of the four corners of the cover body 422 as a first connecting portion, and a second connecting hole 416, such as a threaded hole, is also correspondingly provided at each of the four corners of the end shell 414 as a second connecting portion. The connecting members may be screws, studs, etc. Therefore, through multi-point positioning, the rectangular end cover 42 can accurately and smoothly abut against the housing 41, especially the end housing 414, and be reliably fixed by the connecting parts, thereby forming an excellent seal for the interior of the housing 41.

[0031] Please refer to Figure 1 and 2 Preferably, the motor assembly tooling also includes a positioning guard plate 5 located on the outside of the base 2, and each positioning guard plate 5 is provided with a positioning groove 51 for supporting and positioning the end shell 414. By setting the positioning guard plate 5, it can not only prevent damage to the casing 41 during the assembly process, but also guide the end cover 42 to be placed on the casing 41.

[0032] Please refer to Figure 3 Specifically, the positioning guard plate 5 is provided with a recessed hole 52. When the shell end surface of the intermediate shell 413 is supported on the seat top surface of the base 2, the positioning grooves 51 are arranged on both sides of the recessed hole 52. The recessed hole 52 exposes part of the intermediate shell 413 to the outside. It can also be said that in the vertical upward direction relative to the plane where the bottom plate 1 is located, the positioning groove 51 is higher than the bottom end of the recessed hole 52, so that the lower surface of the end shell 414 is located above the recessed hole 52 of the part of the intermediate shell 413 exposed. Therefore, it is convenient for the operator to grasp the casing 41 with fingers relative to the recessed hole 52 of this part, especially the lower surface of the end shell 414 of the casing 41, so as to lift the casing 41 and relatively move it away from the positioning guard plate 5.

[0033] Please refer to Figure 3Preferably, the number of the cover boss 423, the shell boss 415 and the positioning column 3 are all set to three, so that the three-point positioning function is realized, ensuring that the housing 41 is correctly placed in the motor assembly tooling, thereby realizing the accurate and complete fixation between the housing 41 and the end cover 42. The positioning guard plates 5 are set as a pair of opposite positions, the two positioning columns 3 and the other positioning column 3 are respectively located on both sides of a pair of long rectangular cover edges of the cover body 422, and the pair of positioning guard plates 5 are respectively located on both sides of a pair of short rectangular cover edges of the cover body 422. By relatively setting the positioning guard plates 5 as a pair, the housing 41 can be symmetrically guided to be placed steadily and accurately on the positioning columns 3 and the base 2. Moreover, the pair of positioning guard plates 5 and the three positioning columns 3 are distributed around the housing 41 and the end cover 42, thereby playing a comprehensive protective role for the housing 41 and the end cover 42 to prevent accidental impact by external forces.

[0034] Please refer to Figure 1 Preferably, the motor assembly tool further includes a support plate 6 and a pair of limit blocks 7, the base plate 1 is mounted on the support plate 6, and the pair of limit blocks 7 are rotatably mounted on the support plate 6 and are located at opposite sides of the base plate 1. When the limit blocks 7 are rotated to face the base plate 1, the limit blocks 7 press against the base plate 1 to limit its displacement in a direction perpendicular to the support plate 6. When the limit blocks 7 are rotated to be offset from the base plate 1, the limit blocks 7 allow the base plate 1 to separate from the support plate 6. In this way, the base plate 1 of the motor assembly tool and other components mounted thereon can be moved and installed on the support plate 6 at other positions according to actual needs, and the pair of limit blocks 7 can ensure that the base plate 1 is firmly mounted on the support plate 6 by applying a pressing force.

[0035] Please refer to Figure 1 and Figure 2 Specifically, the motor assembly tool further includes a pair of handles 8 fixed on the bottom plate 1, the bottom plate 1 is set to be a rectangular body, the pair of handles 8 are set at a pair of obliquely symmetrical angles of the bottom plate 1, and a pair of limit blocks 7 are relatively arranged outside another pair of obliquely symmetrical angles of the bottom plate 1. Therefore, the obliquely symmetrically arranged handles 8 facilitate more stable movement of the bottom plate 1 and more reasonable application of the force acting on the bottom plate 1 to separate it from the support plate 6, while the obliquely symmetrically arranged limit blocks 7 can apply a symmetrical pressure to the bottom plate 1 relative to the center of the bottom plate 1, so that the bottom plate 1 is subjected to a more uniform force, thereby preventing the bottom plate 1 and the support plate 6 from accidentally shifting better.

[0036] Specifically, the motor 4 is a motor for a reducer of a new energy vehicle. In this case, since the motors of the reducers of new energy vehicles are being used more and more widely and have higher requirements for assembly reliability and precision, the motor assembly tooling of the utility model can especially meet the assembly requirements for the motors of the reducers of new energy vehicles. In addition, the motor assembly tooling also has the advantages of simple tooling, low cost, simpler operation, long service life and improved assembly efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been 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. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
