[0032] The present utility model provides an assembly tooling.

[0033] Combined with Figure 1 and Figure 2As shown in the figure, in an embodiment of the present utility model, the assembly tooling includes: an assembly table 10, a guiding member, a rotor fixing assembly 30, and a stator base 40. The guiding member is disposed on the assembly table 10 and extends along a first direction; the rotor fixing assembly 30 is disposed on the assembly table 10 and is coaxially spaced from the guiding member along the first direction. The guiding member and the rotor fixing assembly 30 are used to fix the rotor 60; the stator base 40 is movably disposed on the assembly table 10 along the first direction, and the stator base 40 is used to mount the stator 50 that passes through the guiding member.

[0034] Push the stator base 40 to drive the stator 50 to slide along the guiding member, so that the stator 50 is sleeved on the rotor 60.

[0035] In this embodiment, the assembly table 10 is made of a metal with relatively high hardness such as steel or iron to ensure sufficient strength and stability to support the weights of the stator 50 and the rotor 60 and guarantee the stability of the assembly process.

[0036] A chute is provided on the end face of the assembly table 10 facing the stator base 40, or rollers are provided on the end face of the stator base 40 facing the assembly table 10, so that the stator base 40 can slide or roll relative to the assembly table 10.

[0037] The rotor fixing assembly 30 can be fixedly disposed on the assembly table 10 or can be movably disposed on the assembly table 10 along the first direction. When the rotor fixing assembly 30 is fixedly disposed on the assembly table 10, the rotor fixing assembly 30 can be fixed to the assembly table 10 by bolts, rivets or pins 35. At this time, fixing grooves are provided on the surface of the rotor fixing assembly 30 and / or the guiding member. By placing the two ends of the rotor 60 in the fixing grooves, the rotor 60 is supported and fixed between the guiding member and the rotor fixing assembly 30.

[0038] When the rotor fixing assembly 30 is movably disposed on the assembly table 10 along the first direction, the rotor fixing assembly 30 is moved to press against the assembly table 10.

[0039] Furthermore, rubber rings are respectively provided at one ends of the guiding member, the rotor fixing assembly 30 and the rotor 60 connected thereto. The two ends of the rotor 60 are buckled into the rubber rings, and the rotor 60 is fixed between the guiding member and the rotor fixing assembly 30 through elastic extrusion to improve the stability of fixing the rotor 60. Structures such as grooves, clamps, threads, etc. can also be provided at the ends of the guiding member and the rotor fixing assembly 30 to fix the rotor 60. Any solution that can stably fix the rotor 60 between the guiding member and the rotor fixing assembly 30 belongs to the protection scope of the present utility model.

[0040] The first direction in this application is Figure 2 the positive direction of the X-axis.

[0041] Combined with Figure 1 andFigure 2 As shown, in an embodiment of the present utility model, the rotor fixing assembly 30 includes a push rod 31 and a driving member connected to each other. The push rod 31 extends along a first direction, and the driving member is installed on the assembly table 10 and is drivingly connected to the push rod 31;

[0042] The driving member drives the push rod 31 to move towards the stator seat 40, so that the rotor 60 is clamped between the guiding member and the push rod 31.

[0043] In this embodiment, the driving member can be a motor, a cylinder or a hydraulic cylinder structure, which drives the push rod 31 to generate a thrust opposite to the first direction, thereby driving the push rod 31 to move towards the stator seat 40.

[0044] The driving member can also be an elastic member. When the rotor 60 is placed between the guiding member and the push rod 31, the elastic member is squeezed to generate an elastic force opposite to the first direction. The elastic force is transmitted to the push rod 31 through the driving member, so that the rotor 60 is clamped between the guiding member and the push rod 31.

[0045] The driving member can also be a telescopic sleeve. The telescopic sleeve includes an outer sleeve and an inner sleeve connected by threads. By rotating the outer sleeve or the inner sleeve, the length of the telescopic sleeve is compressed to generate a compressive force opposite to the first direction, so that the rotor 60 is clamped between the guiding member and the push rod 31.

[0046] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, the guiding member is a guiding rod 20. One end of the guiding rod 20 is installed on the assembly table 10, and the other end is coaxially spaced from the push rod 31. A first installation groove is formed on the end face of the guiding rod 20 facing the push rod 31, and a second installation groove is formed on the end face of the push rod 31 facing the guiding rod 20. The first installation groove and the second installation groove are used for inserting the rotating shafts at both ends of the rotor 60.

[0047] In this embodiment, the guiding rod 20 is made of high-strength alloy steel material, has excellent wear resistance and anti-deformation ability. One end of the guiding rod 20 is installed on the assembly table 10 by welding, threaded connection or pin. The first installation groove and the second installation groove are respectively adapted to the two ends of the rotor 60, so that when the rotor 60 is inserted, it can not only be closely fitted, but also support the rotor 60 in the direction perpendicular to the first direction, that is, the vertical direction, thereby further improving the stability of the rotor 60.

[0048] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, the driving member is an elastic member, and both ends of the elastic member are respectively connected to the push rod 31 and the assembly table 10.

[0049] In this embodiment, the elastic member can be a spring 32 or an airbag, and its material has sufficient elastic limit and good fatigue strength to avoid deformation and fatigue fracture during repeated compression and expansion. When the elastic member is a spring 32, the spring 32 can be fastened to the push rod 31 by bolts, nuts or snap rings, or a mounting plate is set between the spring 32 and the push rod 31, so that the spring 32 is connected to the push rod 31 through the mounting plate; the spring 32 can be directly fixed on the assembly table 10 by welding, or a spring seat is set on the assembly table 10, and the spring 32 is fixed in the spring seat by fasteners. When the elastic member is an airbag, the airbag is in contact with the push rod 31, or a mounting plate is set between the push rod 31 and the airbag, and the airbag is in contact with the mounting plate.

[0050] The push rod 31 applies elastic force to the rotor 60 through the elastic member, so that the rotor 60 is pressed between the push rod 31 and the guide member. After the stator 50 and the rotor 60 are assembled, the elastic member is further compressed in the first direction to increase the distance between the rotor fixing assembly 30 and the guide member, thereby facilitating the removal of the assembled stator 50 and the rotor 60.

[0051] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the rotor fixing assembly 30 also includes a blocking plate 33, the elastic member is a spring 32, the spring 32 is arranged between the blocking plate 33 and the assembly platform 10, and the push rod 31 is installed on the side of the blocking plate 33 away from the spring 32.

[0052] In this embodiment, a blocking plate 33 is arranged between the spring 32 and the push rod 31. The spring 32 elastically abuts against the blocking plate 33, thereby driving the push rod 31 to move. There is a large contact area between the blocking plate 33 and the spring 32 to improve the stability when the spring 32 drives the blocking plate 33 and the push rod 31 to move. Compared with the solution in which the spring 32 is directly connected to the push rod 31, the elastic force is transmitted to the push rod 31 through the blocking plate 33, thereby preventing the push rod 31 from deflecting when subjected to the elastic force, thereby increasing the stability of the rotor fixing assembly 30.

[0053] Combination Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the assembly table 10 includes a base plate 11 and a side plate 12 vertically connected to the base plate 11, the rotor fixing assembly 30 also includes a center column 34, a blocking plate 33 is arranged at one end of the center column 34, the side plate 12 is provided with a mounting hole, the other end of the center column 34 is movably inserted into the mounting hole, and the spring 32 is sleeved on the outer periphery of the center column 34, and the two ends are respectively abutted against the blocking plate 33 and the side plate 12.

[0054] In this embodiment, the bottom plate 11 is the basic part of the assembly table 10 and is made of a sturdy and durable material, such as high-strength steel plate or aluminum alloy, to support the weight of the entire assembly table 10 and maintain stability. The materials of the two side plates 12 should match that of the bottom plate 11 to ensure the consistency and strength of the overall structure. The bottom plate 11 and the side plates 12 are tightly connected by welding or plugging. The guiding member and the rotor fixing assembly 30 are installed on the two side plates 12 by welding, threaded connection or pin mounting to improve the stability of the overall structure.

[0055] The blocking plate 33 and the central column 34 can be of an integrally formed structure or can be connected by means of threads, welding, etc. The central column 34 further includes a limiting portion to limit the moving distance of the central column 34 within the mounting hole.

[0056] Furthermore, the inner surface of the mounting hole is provided with a guide rail or a chute extending in the first direction, and the outer surface of the central column 34 is provided with a matching groove or slider so that the central column 34 slides through the mounting hole.

[0057] Combined Figure 2 、 Figure 3 and Figure 4 As shown in, in an embodiment of the present utility model, the central column 34 is provided with a limiting channel 341 along its axial direction, and the limiting channel 341 penetrates the central column 34 perpendicular to the first direction;

[0058] The rotor fixing assembly 30 further includes a limiting member that passes through the side plate 12 and is disposed in the limiting channel 341 to limit the moving distance of the central column 34 in the first direction.

[0059] In this embodiment, the longitudinal cross-sectional shape of the limiting channel 341 is rectangular, the limiting member is a pin 35, the shape of the pin 35 can be cylindrical or conical, and the size of the pin 35 is adapted to or smaller than the size of the limiting channel 341 to ensure that the pin 35 can pass through and be positioned in the limiting channel 341. The pin 35 is fixed to the side plate 12 by a locking nut or a snap ring, etc. The pin 35 can be disposed through the side plate 12 or not through the side plate 12, and both can achieve the purpose of limiting the moving distance of the central column 34.

[0060] By limiting the moving range of the central column 34 with the pin 35, it is prevented that the central column 34 breaks away from the outside of the mounting hole under the elastic force of the spring 32, so as to improve the stability and reliability of the rotor fixing assembly 30.

[0061] In other embodiments, the diameter of the end of the central column 34 away from the blocking plate 33 and extending out of the mounting hole can also be designed to be larger than the diameter of the mounting hole, which can also achieve the effect of limiting the central column 34 from falling off the mounting hole.

[0062] Combined Figure 1And Figure 2 As shown, in an embodiment of the present utility model, a support groove 41 is recessed on the side surface of the stator base 40 away from the bottom plate 11. The longitudinal section of the support groove 41 is semi-circular, and the support groove 41 is used to cooperate with the outer peripheral wall of the stator 50.

[0063] In this embodiment, the groove wall of the support groove 41 is in close fit with the outer peripheral wall of the stator 50, forming a uniform supporting force, so that the stator 50 can be stably placed in the support groove 41, increasing the contact stability between the stator 50 and the stator base 40. At the same time, the support groove 41 extends along the first direction, so that after the stator 50 is placed in the support groove 41, the axis of the stator 50 is arranged along the first direction.

[0064] In other embodiments, the stator base 40 is provided with a fixing member, and the stator is fixed in the support groove through the fixing member. The fixing member can be structures such as clamping jaws, vacuum suction holes, and limiting blocks.

[0065] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, a limiting groove 111 is recessed on the surface of the bottom plate 11. The limiting groove 111 extends along the first direction, and one end of the stator base 40 close to the bottom plate 11 is embedded in the limiting groove 111;

[0066] In this embodiment, the bottom of the stator base 40 can be directly inserted into the limiting groove 111, so that the bottom of the stator base 40 is slidably connected to the bottom of the limiting groove 111, or rollers can be provided at the bottom of the stator base 40, so that the stator base 40 can smoothly move on the bottom plate 11.

[0067] The stator base 40 is restricted in the limiting groove 111, and the two opposite side walls of the limiting groove 111 limit the moving direction of the stator base 40 and the stator 50, avoiding the deviation of the stator base 40 and the stator 50 during the moving process, and further improving the alignment accuracy between the stator 50 and the rotor 60.

[0068] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present utility model, the assembly table 10 further includes a sliding rod 13. The two ends of the sliding rod 13 are respectively installed on the two side plates 12.

[0069] The stator base 40 is provided with a sliding hole, and the stator base 40 is movably sleeved outside the sliding rod 13 through the sliding hole.

[0070] In this embodiment, the slide bar 13 is made of materials such as metal or high-strength plastic, and has sufficient rigidity and wear resistance. The sliding hole matches the diameter of the slide bar 13, so that the stator seat 40 is sleeved outside the slide bar 13 through the sliding hole and smoothly moves along the slide bar 13. The setting of the slide bar 13 further limits the moving direction of the stator seat 40. By setting the axial direction of the slide bar 13 along the first direction, the alignment accuracy between the stator 50 and the rotor 60 is further improved.

[0071] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
