Description

Technical Field

[0001] The invention relates to the technical field of rotor assembly, in particular to an automatic pressing-in device for a motor rotor using a heating assembly method. Background Art

[0002] Generally speaking, the motor rotor is the rotating part of the motor. Part of the motor rotor is composed of two shaft heads, a magnetic steel core shaft and a shaft sleeve. The shaft head, the magnetic steel core shaft and the shaft sleeve are coaxially arranged. The specific connection relationship is that the two shaft heads are respectively bonded to the two ends of the magnetic steel core shaft, and the shaft sleeve is interference-fitted on the outer periphery of the magnetic steel core shaft.

[0003] There are many existing ways to connect the rotor and the shaft, and heating assembly is one of them. However, in the existing heating assembly, the rotor to be assembled is usually placed on a corresponding turntable, and the heat assembly effect between the rotor and the shaft is completed by heating and pressing. Although this method can achieve the heat assembly effect between the two, this method uses three different devices to complete the final assembly effect. Therefore, on the one hand, it is necessary to move the rotor to different positions. If the rotor shakes during the movement, it is very likely to cause the rotor angle to shift, which will cause deviations in subsequent heating and assembly, so as to cause unnecessary damage to the rotor, thereby causing waste.

[0004] On the other hand, performing different steps of hot assembly of the rotor by three kinds of equipment respectively increases the final hot assembly time of the rotor to a certain extent, thereby increasing the cost for the user to a certain extent.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] See also Figure 1-Figure 4, an automatic pressing device for a motor rotor using a heating assembly type, comprising an assembly base plate 1, an assembly component 2, a heating component 3 and an installation component 4, an assembly casing 101 is integrally arranged on the assembly base plate 1, and a rotating shaft 119 is also movably arranged inside the assembly casing 101, and a plurality of connecting sleeves 205 are fixedly sleeved on the rotating shaft 119, and the assembly component 2 and the installation component 4 are both fixedly connected with the corresponding connecting sleeves 205 through the connecting sleeve rod 206, and the assembly component 2 and the installation component 4 are both provided with two groups, each group of the assembly component 2 and the installation component 4 are arranged correspondingly to each other, and a group of heating components 3 is also arranged between each group of the assembly component 2 and the heating component 3;

[0039] The assembly component 2 is used to place the rotating rod and assemble the corresponding rotating rod with the corresponding rotor, and the heating component 3 movably arranged under the assembly component 2 is used to heat the rotor accordingly, and the installation component 4 is used to place the corresponding rotor and fix the rotor accordingly.

[0040] Each group of mounting components 4 is composed of a mounting base plate 401, an arc-shaped fixed plate 402 and a third connecting slide rod 403. The mounting base plate 401 is symmetrically provided with a ninth movable slide groove 404, and there are two arc-shaped fixed plates 402, and each arc-shaped fixed plate 402 is slidably set in the corresponding ninth movable slide groove 404 through the third connecting slide rod 403.

[0041] The mounting base plate 401 is movably arranged on the top surface of the movable base plate 107, and the movable base plate 107 is fixedly arranged inside the assembly casing 101. The surface of the movable base plate 107 is also provided with a third movable groove 108 and a fifth movable groove 112, respectively. The bottom ends of the two third connecting slide bars 403 respectively penetrate the mounting base plate 401, and the bottom ends of the two third connecting slide bars 403 are movably arranged inside the third movable groove 108 and the fifth movable groove 112.

[0042] A fourth movable groove 110 is also provided on the side of the third movable groove 108 close to the center position of the movable base plate 107, and the third movable groove 108 and the fourth movable groove 110 are connected to each other, and a sixth movable groove 113 is also provided on the side of the fifth movable groove 112 away from the center position of the movable base plate 107, and the fifth movable groove 112 and the sixth movable groove 113 are connected to each other.

[0043] In this embodiment: since a movable base plate 107 is provided inside the assembly casing 101, and two groups of mounting components 4 are respectively provided on the top surface of the movable base plate 107, and each group of mounting components 4 is fixedly connected to the rotating shaft rod 119 through the connecting sleeve 205 and the connecting sleeve rod 206, when the rotating shaft rod 119 is rotated by the external motor, the two groups of mounting components 4 will also synchronously follow the rotating shaft rod 119 to perform a corresponding rotation effect on the movable base plate 107;

[0044] At the same time, since two arc-shaped fixing plates 402 are arranged on each mounting base plate 401, and each arc-shaped fixing plate 402 is slidably arranged inside the ninth movable slide groove 404 through an integrally arranged third connecting slide rod 403, and the bottom ends of the two third connecting slide rods 403 are also slidably arranged inside the third movable slide groove 108 and the fifth movable slide groove 112 respectively;

[0045] It should be noted that when the rotor is placed, the two third connecting slide bars 403 are slidably arranged inside the fourth moving slide groove 110 and the sixth moving slide groove 113, and when the mounting base 401 rotates following the rotating shaft 119, as one third connecting slide bar 403 slides from the fourth moving slide groove 110 via the third moving station 109 to the inside of the third moving slide groove 108, this third connecting slide bar 403 will drive the corresponding arc-shaped fixed plate 402 to squeeze the inner wall of one side of the rotor, and finally as another third connecting slide bar 403 slides from the sixth moving slide groove 113 via the sixth moving station 115 to the inside of the fifth moving slide groove 112, this third connecting slide bar 40 3 will also drive the corresponding arc-shaped fixing plate 402 to complete the extrusion of the inner wall on the other side of the rotor; in this way, the rotor can be guaranteed to be fixed in the center position of the mounting base plate 401 to a certain extent during subsequent heating or assembly, and when the mounting base plate 401 is fixed in the center position, the subsequent heating or assembly can be carried out more effectively. The above method can also avoid the problem that in the existing installation technology, the rotor can only be simply sleeved on the fixing seat. If the rotor shakes during the rotation process, resulting in an angle deviation, it is very likely to cause deviations in subsequent heating and assembly, so as to cause unnecessary damage to the rotor, thereby causing waste.

[0046] It should be noted that, since a fourth moving station 111 is provided between the third moving slot 108 and the fourth moving slot 110, the fourth moving station 111 is provided so that after the rotor is assembled, the third connecting slide bar 403 can be moved to the inside of the fourth moving slot 110 through the fourth moving station 111, thereby releasing the squeezing and fixing effect of the arc-shaped fixing plate 402 on the rotor, so that the user can remove the rotor. Similarly, the fifth moving station 114 is provided between the fifth moving slot 112 and the sixth moving slot 113 so that the corresponding arc-shaped fixing plate 402 can release the squeezing and fixing effect on the rotor.

[0047] It should be noted that a material taking trough 122 is also provided on the surface of the assembly casing 101 on one side close to the fourth moving chute 110 and the sixth moving chute 113, and the material taking trough 122 is provided to facilitate the installation and placement of the rotor in the early stage, and to facilitate the unloading and taking of the rotor after the later assembly is completed, and the material taking trough 122 is provided on one side of the fourth moving chute 110 and the sixth moving chute 113 because the rotor is in an unfixed state only when it is in the fourth moving chute 110 and the sixth moving chute 113, and only the rotor in an unfixed state can be installed and placed and unloaded and taken;

[0048] It should be noted that the ninth movable slide groove 404 is provided, on the one hand, to allow the third connecting slide bar 403 to move stably when performing the corresponding movement, and on the other hand, to prevent the third connecting slide bar 403 from getting stuck when moving.

[0049] Embodiment 2

[0050] This embodiment is an improvement made on the basis of the first embodiment. Figure 2 As shown, each group of heating components 3 is provided with a heating sleeve 301, and the top outer edge of each heating sleeve 301 is movably arranged inside the corresponding assembly box 201 through two second connecting slide bars 304, and the top of each second connecting slide bar 304 is connected to an extruded top plate 220, and the top surface of the extruded top plate 220 close to the storage slot 207 is in contact with the second airbag 213, and the bottom surface of each extruded top plate 220 is connected to the assembly box 201 through two connecting springs 221.

[0051] A connecting groove 222 is also opened on one side of the second airbag 213, and an air pipe 223 is arranged inside the connecting groove 222. One end of the air pipe 223 is connected to the second airbag 213, and the other end of the air pipe 223 is connected to the first airbag 212. The surface of the side of the first airbag 212 away from the second airbag 213 is also connected to the sealing plate 211. The sealing plate 211 is used to limit and seal the assembly groove 210.

[0052] The surface of each heating sleeve 301 is also arranged inside the lifting slide groove 106 and the first movable slide groove 102 respectively through two first connecting slide rods 302. The lifting slide groove 106 is opened on the rotating shaft 119, and the first movable slide groove 102 is opened on the inner wall of the assembly casing 101. A second movable slide groove 104 is also opened on the inner wall of the assembly casing 101, and the height of the second movable slide groove 104 is lower than the height of the first movable slide groove 102.

[0053] In this embodiment: since a heating component 3 is correspondingly arranged above each group of mounting components 4, and each group of heating components 3 moves synchronously with the corresponding assembly component 2, and each group of mounting components 4 and assembly components 2 are fixedly sleeved on the rotating shaft 119 through the same connecting sleeve 205 and connecting sleeve rod 206, each group of assembly components 2 and the corresponding heating component 3 will synchronously follow the mounting component 4 to perform the corresponding movement effect, and this arrangement is to enable the rotor to complete the corresponding heating and corresponding assembly effect according to different moving positions during the rotation process, thereby improving the thermal assembly efficiency between the rotor and the corresponding rotating shaft to a certain extent;

[0054] Since the heating sleeve 301 in each group of heating components 3 is slidably arranged in the first movable slide groove 102 and the lifting slide groove 106 respectively through two first connecting slide rods 302, and the first movable slide groove 102 and the lifting slide groove 106 are respectively opened at the inner wall of the assembly sleeve 101 and inside the rotating shaft 119, the lifting slide groove 106 is opened to allow the heating sleeve 301 to move downward smoothly during the subsequent heating to avoid jamming;

[0055] A second movable slot 104 is also provided on the inner wall of the assembly casing 101, and the opening height of the second movable slot 104 is smaller than the opening height of the first movable slot 102, and the first movable slot 102 and the second movable slot 104 are connected via the first movable station 103 and the second movable station 105. Therefore, when the first connecting slide bar 302 provided inside the first movable slot 102 moves to the inside of the second movable slot 104 via the first movable station 103, the heating sleeve 301 will also synchronously move downward accordingly. When the first connecting slide bar 302 moves to the inside of the second movable slot 104, the heating sleeve 301 is sleeved on the surface of the rotor, and the heating wire 303 provided inside the heating sleeve 301 can start heating the rotor.

[0056] This arrangement is also to allow the rotor to be heated during its movement, thereby improving the thermal assembly efficiency of the rotor to a certain extent;

[0057] It should be noted that when the heating sleeve 301 completes heating, the heating sleeve 301 will be moved again from the second movable station 105 to the inside of the first movable slot 102 through the first connecting slide rod 302. In this way, the first connecting slide rod 302 can stop the heating effect on the rotor surface.

[0058] Embodiment 3

[0059] This embodiment is an improvement made on the basis of the first and second embodiments. Figure 2 , Figure 5-Figure 10 As shown, each group of assembly components 2 is provided with an assembly box 201, and a storage slot 207 and an assembly slot 210 are respectively opened inside the assembly box 201, and a movable inclined surface 209 is also opened between the storage slot 207 and the assembly slot 210, and the storage slot 207 and the assembly slot 210 are connected through the movable inclined surface 209, the storage slot 207 is used to place a corresponding number of rotating rods, and the assembly slot 210 is used to place the corresponding assembled rotating rods.

[0060] A movable member 208 is also movably arranged inside the assembly groove 210, and a fixed connection is formed between the top of the movable member 208 and the first assembly rod 202, and the first assembly rod 202 is fixedly connected with one end of the first movable slide rod 203 through the connecting plate 204, and a connecting ball 219 is arranged at the other end of the first movable slide rod 203, and the first movable slide rod 203 is slidably arranged inside the seventh movable slide groove 116 through the connecting ball 219, and the seventh movable slide groove 116 is opened between the assembly casing 101 and the assembly base plate 1.

[0061] A connecting shaft 218 is also provided inside the moving part 208, and a moving gear 217 is fixedly sleeved on the connecting shaft 218, and the moving gear 217 is meshed with a moving tooth mouth 216, and the moving tooth mouth 216 is opened on the inner wall of one side of the assembly groove 210, and the moving gear 217 is also meshed with a moving rack 215, and the moving rack 215 is opened on the surface of the second assembly rod 214, and the second assembly rod 214 is movably arranged inside the moving part 208.

[0062] In this embodiment: when the heating sleeve 301 moves down to the second moving slide groove 104 through the first moving station 103, the heating sleeve 301 is movably arranged inside the assembly box 201 through two second connecting slide bars 304, and one of the second connecting slide bars 304 close to the storage groove 207, its top also squeezes the second airbag 213 by squeezing the top plate 220;

[0063] It should be noted that a connecting spring 221 is further provided between the extrusion top plate 220 and the assembly box 201. The provision of the connecting spring 221 is, on the one hand, to allow the heating sleeve 301 to remain in a fixed state below the assembly box 201 through the elastic force of the connecting spring 221 when the heating sleeve 301 does not need to be moved downward. On the other hand, the elastic force of the connecting spring 221 can also allow the extrusion top plate 220 to squeeze the second airbag 213, thereby allowing the inside of the second airbag 213 to The gas can be transported to the interior of the first airbag 212 through the air pipe 223, and connecting guard plates 224 are respectively provided at both ends of the first airbag 212, and a compression spring 225 is also provided inside the first airbag 212, and both ends of the compression spring 225 are respectively fixedly connected to the two connecting guard plates 224. It should be noted that the connecting guard plate 224 close to the second airbag 213 is fixedly arranged inside the assembly box 201, and the connecting guard plate 224 far from the second airbag 213 is movably arranged inside the assembly box 201;

[0064] Therefore, when gas is injected into the first airbag 212, the connecting guard plate 224 on the side away from the second airbag 213 will move away from the second airbag 213, and the connecting guard plate 224 away from the second airbag 213 is also fixedly connected to the blocking plate 211, so that the blocking plate 211 will move synchronously, thereby completing the blocking effect of the assembly through groove 210;

[0065] From the above, it can be known that when the second connecting slide bar 304 moves downward, the squeezing top plate 220 will release the squeezing of the second airbag 213, so that the gas injected into the first airbag 212 will return to the second airbag 213 again, and when the gas in the first airbag 212 is lost, the connecting guard plate 224 away from the second airbag 213 will bring the blocking plate 211 to reset, thereby releasing the blocking of the assembly slot 210, so that the rotating rod in the assembly slot 210 at this time falls from the assembly slot 210 into the rotor below, thereby completing the initial connection effect between the rotor and the rotating rod;

[0066] At the same time, since a moving member 208 is also provided inside the assembly groove 210, and the upper part of the moving member 208 is also fixedly connected to the first assembly rod 202, and the first assembly rod 202 is fixedly connected to one end of the first moving slide rod 203 through the connecting plate 204, and the other end of the first moving slide rod 203 is slidably provided inside the seventh moving slide groove 116 through the connecting ball 219, and a plurality of eighth moving slide grooves 121 are intermittently provided below the seventh moving slide groove 116, and the seventh moving slide groove 116 and the corresponding eighth moving slide groove 121 are connected through the corresponding seventh moving station 117 and the eighth moving station 118;

[0067] It should be noted that when the heating sleeve 301 moves from the first moving groove 102 to the second moving groove 104, the connecting ball 219 also enters the seventh moving station 117 from the seventh moving groove 116. Through the above arrangement, the first moving slide bar 203 can slide in sequence between the seventh moving groove 116 and the plurality of eighth moving grooves 121, thereby performing reciprocating motion in the up and down directions.

[0068] It should be noted that, since the limiting strips 120 are further provided at the inner walls on both sides of the seventh movable slide groove 116, and the setting of the limiting strips 120 is set corresponding to the height of the seventh movable slide groove 116 and the eighth movable slide groove 121, when the connecting ball 219 slides in the seventh movable slide groove 116 or in the eighth movable slide groove 121, the limiting strips 120 can also smoothly allow the connecting ball 219 to perform a limited sliding effect in the seventh movable slide groove 116 or the eighth movable slide groove 121;

[0069] When the first moving slide bar 203 reciprocates in the up and down directions, the first assembly rod 202 which is fixedly connected with the other end of the first moving slide bar 203 through the connecting plate 204 will also reciprocate synchronously. When the first assembly rod 202 moves downward, the moving member 208 which is fixedly connected with the other end of the first assembly rod 202 will also move downward accordingly under the meshing action of the connecting shaft 218 and the moving gear 217. On the one hand, the second assembly rod 214 is arranged inside the moving member 208 through the meshing activity between the moving rack 215 and the moving gear 217. After the first assembly rod 202 is moved down, the second assembly rod 214 will also move down accordingly. On the other hand, due to the meshing effect of the moving rack 215 and the moving gear 217, the second assembly rod 214 will also move down again. With this arrangement, the second assembly rod 214 does not need to move down much height of the first assembly rod 202 to effectively complete the extrusion assembly effect on the rotating rod. When the second assembly rod 214 contacts the rotating shaft, the initial extrusion of the rotor and the rotating shaft can be completed. As the reciprocating motion proceeds, the rotating shaft will also complete the thermal assembly effect with the rotating rod under the indirect extrusion effect of the second assembly rod 214.

[0070] By making the first assembly rod 202 reciprocate so that the second assembly rod 214 intermittently squeezes the rotating shaft, the purpose is to make the assembly hole diameter of the rotor gradually increase after expansion occurs in the heated state. When facing different assembly hole diameters, the rotating rod can complete the connection effect once when facing different assembly hole diameters through intermittent squeezing, so that the connection between the two is more precise and the assembly process can be smoother.

[0071] It should be noted that before a rotating shaft completes the entire assembly, the rotating shaft in the storage slot 207 will not enter the assembly slot 210 due to the obstruction of the rotating shaft in the assembly slot 210. When the rotating shaft in the assembly slot 210 completes the assembly, the second assembly rod 214 moves downward, and the second assembly rod 214 also limits the rotating shaft in the storage slot 207. Only when the second assembly rod 214 is reset, the next rotating shaft will fall into the assembly slot 210.

[0072] Through the above-mentioned arrangement, not only during the rotation of the rotor, the heating sleeve 301 can be effectively moved up and down by opening the first movable groove 102 and the second movable groove 104, thereby completing the heating effect of the rotor, but also compared with the prior art, the present solution can also allow the rotor to be heated while allowing the first movable slide bar 203 to reciprocate inside the seventh movable groove 116, so that the second assembly rod 214 can squeeze the rotating shaft at intervals, thereby better completing the corresponding thermal assembly effect between the rotor and the rotating shaft, and in this way, the thermal assembly efficiency of the rotor and the rotating shaft is also effectively improved.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
