[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is a power element for many devices. The sealing performance of the motor determines the service life and maintenance interval of the motor. Usually, the motor includes an upper cover and a lower cover.

[0045] Before further describing the embodiments of the present invention in detail, the directional nouns involved in the embodiments of the present invention, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the protection scope of the present invention.

[0046] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0047] Figure 1 A schematic diagram of a motor casing disassembly device according to an embodiment of the present invention; Figure 7 Schematic diagram of a motor to be disassembled according to an embodiment of the present invention.

[0048] like Figure 1 and Figure 7 As shown, an embodiment of the present invention provides a disassembling device 100 for a motor housing, wherein the motor housing 200 includes a lower cover 220 and an upper cover 210 which is jacketed on the lower cover 220, the lower cover 220 and the upper cover 210 are glued together, and a connecting ear 221 is provided at one end of the lower cover 220 away from the upper cover 210, and the disassembling device 100 includes:

[0049] The support frame 110 includes a slideway, and the connecting ear 221 is configured to slide into the slideway;

[0050] A fixing member 120, wherein a connection port is provided at the center of the fixing member 120, and the shape of the connection port matches the shape of the upper cover 210. A fixing pin is provided on the fixing member 120, and the fixing pin passes through the fixing member 120 and abuts against the upper cover 210;

[0051] The stretching member 130, part of which is connected to the support frame 110, so that the stretching member 130 is arranged opposite to the slideway, and part of which is connected to the fixing member 120, and the stretching member 130 drives the fixing member 120 and the upper cover 210 to move away from the connecting ear 220 in turn.

[0052] The disassembling device 100 includes a support frame 110, and the support frame 110 includes a slideway, through which the lower cover 220 of the motor 200 housing can be stabilized, and then connected to the fixing member 120 through the upper cover 210, the connection port of the fixing member 120 matches the shape of the upper cover 210, and the contact area between the fixing member 120 and the upper cover 210 is increased, and the upper cover 210 is abutted by the fixing pin, and a certain extrusion force is applied to the upper cover 210 to ensure the stability of the upper cover 210 in the fixing member 120, and the fixing member 120 is also connected to the stretching member 130, through The stretching member 130 drives the fixing member 120 and the upper cover 210 to move away from the lower cover 220 in turn. The extrusion force of the plurality of fixing pins is greater than the stretching force, ensuring that the upper cover 210 can also be stably arranged in the fixing member 120 during the stretching process. The stretching force is greater than the bonding force between the upper cover 210 and the lower cover 220, so that the upper cover 210 and the lower cover 220 are separated, and the connection between the upper cover 210 and the lower cover 220 is not damaged, thereby ensuring the reliability of the secondary seal, thereby avoiding abnormal noise of the motor 200 and increasing the service life of the motor 200. At the same time, it also avoids directly replacing the motor 200, and can directly repair small problems of the motor 200, thereby reducing maintenance costs and improving customer satisfaction.

[0053] Specifically, in order to ensure the sealing inside the motor 200, the upper cover 210 and the lower cover 220 of the motor 200 are usually sealed by adhesive. When a problem occurs with the motor 200, the motor 200 needs to be replaced, or the upper cover 210 and the lower cover 220 need to be opened with a screwdriver. However, after opening, deformation occurs between the upper cover 210 and the lower cover 220, affecting the secondary sealing, or the upper cover 210 and the lower cover 220 need to be reshaped and then sealed again, which increases the duration of the secondary sealing and reduces the efficiency of maintenance work. Therefore, through the disassembly device 100 of the present application, the connecting ear 221 of the lower cover 220 is slid into the slideway of the support frame 110, and the lower cover 220 is limited by the slideway, and then the upper cover 210 is connected with the fixing member 120 and the stretching member 130 in turn, and the fixing member 120 and the upper cover 210 are driven to move away from the lower cover 220 by the tension of the stretching member 130, until the tensile force overcomes the gluing force, and the upper cover 210 and the lower cover 220 are separated, so that the connection between the upper cover 210 and the lower cover 220 after the separation does not deform, and the upper cover 210 and the lower cover 220 can be directly glued and sealed after the internal maintenance and inspection of the motor 200 is completed, which ensures the sealing effect on the one hand, and improves the maintenance and inspection efficiency on the other hand because there is no need to perform sheet metal reshaping. At the same time, the cost of replacing or repairing the internal parts of the motor 200 is lower than that of replacing the whole machine, which improves the economy and customer satisfaction.

[0054] Figure 2 Schematic diagram of a support frame according to an embodiment of the present invention.

[0055] In a possible implementation, Figure 2 As shown, the support frame 110 also includes: a top plate 111 and a bottom plate 112, and a plurality of columns 113 arranged between the top plate 111 and the bottom plate 112, a partial tensile member 130 is fixedly connected to the top plate 111, and a slideway is fixedly connected to the bottom plate 112.

[0056] The support frame 110 includes a top plate 111 and a bottom plate 112, and a column 113 supporting the top plate 111 and the bottom plate 112, and the distance between the top plate 111 and the bottom plate 112 is within the telescopic length range of the tensile member 130. That is to say, the distance between the top plate 111 and the bottom plate 112 is not greater than the sum of the height of the motor 200 and the telescopic length of the tensile member 130, so as to ensure that the tensile member 130 effectively applies the tensile force. In this embodiment, the column 113 and the top plate 111, and the column 113 and the bottom plate 112 can be connected by welding, or the column 113 can penetrate into the top plate 111 and / or the column 113 penetrates into the bottom plate 112, that is, the column 113 and the bottom plate 112 and / or the column 113 and the top plate 111 can achieve mechanical tight fit by cold pressing.

[0057] It is understandable that there are at least three columns 113 to ensure the support stability between the top plate 111 and the bottom plate 112. Four columns 113 can also be set to maximize the support reliability between the top plate 111 and the bottom plate 112 while ensuring that the connecting ear 221 of the lower cover 220 can slide smoothly into the slideway. Of course, more than four columns 113 can also be set to increase the stability of the support for the top plate 111 and the bottom plate 112, but it may affect the smooth sliding of the connecting ear 221 into the slideway of the support frame 110, and will also increase the manufacturing cost. Therefore, this embodiment selects four columns 113 to achieve support for the top plate 111 and the bottom plate 112, leaving operating space for other components.

[0058] In a feasible implementation, the slide includes a first slide 114 and a second slide 115 arranged opposite to each other. The first slide 114 and the second slide 115 have the same structure. The first slide 114 includes:

[0059] A first transverse plate 1141 is disposed opposite to the bottom plate 112;

[0060] The first vertical plate 1142 is fixedly connected to the bottom plate 112 . The first horizontal plate 1141 and the first vertical plate 1142 are arranged in an L shape. The space enclosed by the first horizontal plate 1141 , the first vertical plate 1142 and the bottom plate 112 forms a slideway.

[0061] Among them, through the arrangement of the first horizontal plate 1141 and the first vertical plate 1142, the first horizontal plate 1141, the first vertical plate 1142 and the bottom plate 112 are enclosed into a space, that is, a slide is formed, and the connecting ear 221 of the lower cover 220 is slid into the first slide 114 and the second slide 115, and the two slides exert a limited downward pressure on the connecting ear 221, that is, the lower cover 220 can be stabilized, ensuring that when the stretching member 130 is stretched, there is a downward pressure on the connecting ear 221 and the lower cover 220, which helps to effectively disassemble the upper cover 210 and the lower cover 220.

[0062] In a feasible implementation manner, the first horizontal plate 1141 and the first vertical plate 1142 are integrally formed; or

[0063] The first horizontal plate 1141 and the first vertical plate 1142 are connected by welding; or

[0064] The first transverse plate 1141 and the first vertical plate 1142 are connected by bolts.

[0065] Exemplarily, the first transverse plate 1141 of the first slide 114 and the first transverse plate 1141 of the second slide 115 extend toward each other, that is, the first transverse plate 1141 of the first slide 114 and the first transverse plate 1141 of the second slide 115 are arranged relative to each other, so that it is convenient for the connecting ear 221 to slide into the first slide 114 and the second slide 115 at the same time, so as to achieve the balance of pressure on the lower cover 220 and ensure the reliability of the tensile member 130 when it is pulled. The first transverse plate 1141 and the first vertical plate 1142 can be integrally formed, and the first vertical plate 1142 and the bottom plate 112 are penetrated by bolts to achieve the fixed connection between the slide and the bottom plate. Alternatively, the first transverse plate 1141 and the first vertical plate 1142 are welded and connected, and the first vertical plate 1142 and the bottom plate 112 are penetrated by bolts to achieve the fixed connection between the slide and the bottom plate. Alternatively, the first transverse plate 1141 and the first vertical plate 1142 are connected by bolts, and the bolts sequentially penetrate the first transverse plate 1141 , the first vertical plate 1142 and the bottom plate 112 to achieve a fixed connection between the slideway and the bottom plate 112 .

[0066] Figure 3 A schematic diagram of a fixing member according to an embodiment of the present invention from one viewing angle; Figure 4 FIG. 1 is a schematic diagram of a fixing member according to another embodiment of the present invention from another perspective.

[0067] In a possible implementation, Figure 3 and Figure 4 As shown, the fixing member 120 includes:

[0068] The fixed cylinder 121 includes four mutually connected enclosing plates 1211 and a third connecting plate 1212 arranged at one end of the enclosing plates 1211. The space enclosed by the four enclosing plates 1211 and the third connecting plate 1212 forms a connecting port, and the opening of the connecting port is arranged toward the slideway. The fixed cylinder 121 is jacketed on the upper cover 210.

[0069] The connecting member 122 is disposed on a side of the fixed cylinder 121 away from the connecting port. One end of the connecting member 122 is fixedly connected to the third connecting plate 1212 , and the other end of the connecting member 122 is connected to the tensioning member 130 .

[0070] Among them, the fixed cylinder 121 is surrounded by four panels 1211 and a third connecting plate 1212 to form a connection port. The shape of the four panels 1211 facing the connection port should match the outer shell shape of the upper cover 210, which can effectively increase the contact area between the fixed cylinder 121 and the upper cover 210, so as to ensure the reliability and stability of the tensile member 130 when it is pulled. It can be understood that the size of the upper cover 210 of the motor 200 is usually a conventional size, and the fixed cylinder 121 can be prepared by casting and integral molding to ensure that the shape of the internal connection port of the fixed cylinder 121 matches the shape of the upper cover 210. The opening end of the connection port faces the side of the bottom plate 112, which is convenient for sleeve connection with the upper cover 210 of the motor 200.

[0071] It should be noted that after the fixed cylinder 121 is sleeved on the upper cover 210, it is connected to the tensile member 130 through the connecting member 122 on the fixed cylinder 121, so that the tension of the tensile member 130 can be transmitted to the connecting member 122, the fixed cylinder 121 and the upper cover 210 in turn to ensure the separation of the upper cover 210 and the lower cover 220.

[0072] In a feasible implementation manner, a bolt through hole 1213 is provided at one end of the enclosure plate 1211 away from the third connecting plate 1212 , and a fixing pin is provided in the bolt through hole 1213 .

[0073] Among them, a bolt through hole 1213 is provided on the end of the enclosure 1211 away from the third connecting plate 1212. A fixing pin is arranged in the bolt through hole 1213, and an external thread is provided on the fixing pin. The fixing pin is screwed into the connecting port to achieve abutment between the fixing pin and the upper cover 210, and a force is applied to the upper cover 210 to ensure that the upper cover 210 can always be located in the fixed cylinder 121 under the action of the pulling force of the stretching member 130, thereby avoiding separation of the upper cover 210 and the fixed cylinder 121.

[0074] It should be noted that the more fixing pins are set, the more reliable the connection between the fixing cylinder 121 and the upper cover 210 is, but it will affect the installation efficiency of the disassembling device 100. In this application, two bolt through holes 1213 are set on each of the pair of opposite enclosures 1211, which can meet the fixing of the fixing pins to the upper cover 210. In other words, by abutting the upper cover 210 with four fixing pins, the upper cover 210 can be prevented from falling out of the fixing cylinder 121 even under the action of tensile force, ensuring that the tensile force can be effectively applied to the upper cover 210, and ensuring the disassembly of the upper cover 210 and the lower cover 220.

[0075] In a feasible embodiment, the connecting member 122 includes a first hanging ear 1221 and a second hanging ear 1222, the first hanging ear 1221 and the second hanging ear 1222 have the same structure, the first hanging ear 1221 includes: a second horizontal plate and a second vertical plate connected to each other, the second horizontal plate and the second vertical plate are arranged in an L shape, the second vertical plate is fixedly connected to the third connecting plate 1212, and the second horizontal plate is connected to the stretching member 130.

[0076] Among them, the connecting member 122 includes a first hanging ear 1221 and a second hanging ear 1222, and forms an L shape through the setting of the second horizontal plate and the second vertical plate, which is convenient for hanging the first hanging ear 1221 and the second hanging ear 1222 on the stretching member 130, ensuring the connection between the stretching member 130 and the fixing member 120, and further ensuring that the stretching force can be effectively transmitted to the upper cover 210.

[0077] It should be noted that the second vertical plate is fixedly connected to the third connecting plate 1212, and the second horizontal plate is hooked and connected to the tensile member 130. Under the action of the tensile force and the reverse force of the slide, the first hanging ear 1221 and the second hanging ear 1222 are ensured to fit tightly with the tensile member 130, avoiding the first hanging ear 1221 and the second hanging ear 1222 from being detached from the tensile member 130.

[0078] It is understandable that the second horizontal plate and the second vertical plate can be integrally formed or connected by bolts. In this embodiment, the second horizontal plate and the second vertical plate are integrally formed, and the second vertical plate and the third connecting plate are directly connected by bolts to achieve the connection between the connecting member 122 and the fixed cylinder 121, thereby ensuring the connection strength of the first hanging ear 1221 and the second hanging ear 1222, and further ensuring the reliability and effectiveness of the tension transmission.

[0080] In a possible implementation, Figure 5 As shown, the stretching member 130 includes:

[0081] The telescopic cylinder 131 includes a fixed end 1311 and a telescopic end 1312. The fixed end 1311 is fixedly connected to the support frame 110, and the telescopic end 1312 can move toward or away from the slideway.

[0082] The connector 132 is disposed on a side of the telescopic end 1312 facing the slideway, and the connector 132 is connected to the fixing member 120 .

[0083] The stretching member 130 generally includes a telescopic cylinder 131, which may be a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod, and can realize the reciprocating movement of the telescopic end 1312 in the fixed end 1311. A connector 132 is provided on the side of the telescopic end 1312 away from the fixed end 1311, and the connection between the stretching member 130 and the fixed member 120 is realized through the connector 132, that is, the first hanging ear 1221 and the second hanging ear 1222 are hung and connected with the connector 132.

[0084] In this embodiment, the connector 132 is fixedly connected to the telescopic end 1312 by screws, and the screws penetrate the connector 132 and part of the telescopic end 1312 from the side of the connector 132 away from the telescopic end 1312, and the connector 132 is fixedly connected to the telescopic end 1312 by threads. The fixed end 1311 is connected to the top plate 111 by screws, and a through hole is provided on the top plate 111 for the telescopic end 1312 to pass through, so as to ensure the feasibility of the telescopic end 1312 to telescope in the fixed end 1311.

[0085] Figure 6 Schematic diagram of a connector according to an embodiment of the present invention.

[0086] In a possible implementation, Figure 6 As shown, the connector 132 includes:

[0087] A first connecting plate 1321;

[0088] A second connecting plate 1322, the second connecting plate 1322 is arranged opposite to the first connecting plate 1321;

[0089] The connecting column 1323 is arranged between the first connecting plate 1321 and the second connecting plate 1322. The diameter of the connecting column 1323 is smaller than the size of the first connecting plate 1321 and the second connecting plate 1322. The first connecting plate 1321, the connecting column 1323 and the second connecting plate 1322 form a groove, and part of the fixing member 120 is arranged in the groove.

[0090] The connector 132 includes a first connector plate 1321 and a second connector plate 1322 that are arranged opposite to each other, and a connector column 1323 that is arranged between the first connector plate 1321 and the second connector plate 1322, so that the connector 132 forms an I-shape on the vertical surface of the bottom plate 112. In other words, the groove formed at the circumference of the connector column 132 facilitates the connector 122 on the fixing member 120 to slide into the groove, thereby realizing the connection between the fixing member 120 and the tensile member 130.

[0091] It should be noted that the connecting column 1323 is usually arranged at the center of the first connecting plate 1321 and the center of the second connecting plate 1322, so as to ensure that the grooves formed by the connecting column 1323 and the first connecting plate 1321 and the second connecting plate 1322 are uniform, thereby ensuring the uniformity of the contact force between the fixing member 120 and the connecting head 132, improving the uniformity of the tension applied by the tensile member 130, and thereby improving the stability of the tension.

[0092] In a feasible implementation manner, the first connecting plate 1321 is in the shape of a cylinder or a regular polygonal prism; the second connecting plate 1322 is in the shape of a cylinder or a regular polygonal prism; and the connecting column 1323 is in the shape of a cylinder or a regular polygonal prism.

[0093] Exemplarily, the projection of the first connecting plate 1321 on the base plate 112 can be any one of a circle, a square and a regular polygon. Similarly, the projection of the second connecting plate 1322 on the base plate 112 can be any one of a circle, a square and a regular polygon. The shapes of the first connecting plate 1321 and the second connecting plate 1322 can be the same or different.

[0094] In this embodiment, the projection of the second connecting plate 1322 on the bottom plate 112 is a square, which makes it easier to hang the connecting member 122, increases the contact area between the connecting member 122 and the second connecting plate 1322, and ensures the reliability of the hanging.

[0095] In another embodiment, Figure 8As shown, the lower cover 220 of the motor 200 has no hanging ears, and a bolt hole is provided on the side of the lower cover 220 facing away from the upper cover 210. A special-shaped plate 230 is provided on the upper cover 210 of the motor 200, and a connecting groove is provided on the special-shaped plate 230. At this time, a fourth connecting plate 140 can be arranged in the first slide 114 and the second slide 115. The fourth connecting plate 140 is provided with bolt holes, which are corresponding to the bolt holes on the lower cover 220. The lower cover 220 and the fourth connecting plate 140 are fixedly connected by bolts. At the same time, the fourth connecting plate 140 is limited by the first slide 114 and the second slide 115, thereby achieving the limitation of the lower cover 220. At this time, the fixing member 120 includes a clamping plate and a connecting member 122, and the clamping plate includes a first clamping plate 123 and a second clamping plate 124. The first clamping plate 123 and the second clamping plate 124 have the same structure. The first clamping plate 123 includes a third horizontal plate 1231 and a third vertical plate 1232 that are vertically connected. The third vertical plate 1232 is provided with a protrusion, and the protrusion is snap-fitted with the connecting groove. That is to say, the shapes of the first clamping plate 123 and the second clamping plate 124 match the side shape of the special-shaped plate 230, and the snap-fit ​​connection is achieved through the connecting groove and the protrusion. The two third horizontal plates 1231 are connected by bolts, and the two third vertical plates 1231 are adjusted. The distance between the three vertical plates 1232 ensures that the two third vertical plates 1232 can clamp the special-shaped plate 230. The connecting member 122 is the same as the above-mentioned connecting member 122, including a first hanging ear 1221 and a second hanging ear 1222. The first hanging ear 1221 and the second hanging ear 1222 have the same structure. The second vertical plate is fixedly connected to the third horizontal plate 1231, and the second horizontal plate can be hung in the grooves on both sides of the connecting column 1323 to realize the hanging of the fixing member 120 and the tensile member 130, so that the pulling force is transmitted to the fixing member 120 and the upper cover 210 in turn, so as to facilitate the disassembly of the upper cover 210 and the lower cover 220. It can be understood that the other components are the same as the above-mentioned components and will not be repeated. The adjustment of the two third horizontal plates 1231 will not affect the hanging of the first hanging ear 1221 and the second hanging ear 1222, because the margin can be reserved in advance to avoid interference. When the special-shaped plate 230 has a connecting groove on only one side, a protrusion is provided on one of the third vertical plates 1232 to achieve snap-in, and the connection between the two third horizontal plates 1231 is adjusted by bolts, so that the two third vertical plates 1232 can clamp the special-shaped plate 230. At this time, the structure of the first clamping plate 123 and the second clamping plate 124 are slightly different. Those skilled in the art can adapt according to actual conditions, and no further details are given.

[0096] It can be understood that the exterior of the motor in the accompanying drawings is only a schematic diagram. In the first embodiment, it is sufficient to ensure that the connection port of the fixed cylinder and the upper cover are manufactured in accordance with the shape, and in the second embodiment, it is sufficient to ensure that the splint and the special-shaped plate are manufactured in accordance with the shape. Both can achieve the effect of disassembling the upper cover and the lower cover in the present application.
