Description

Technical Field

[0001] This utility model relates to the field of disassembly device technology, and in particular to a disassembly device for motor end caps. Background Technology

[0002] In the production, repair, maintenance, and disposal of electric motors, it is often necessary to separate the motor end covers (such as upper and lower end covers) from the motor body (casing) to inspect, replace, or maintain internal components such as the stator, rotor, and bearings. This need is widespread in the processing of products awaiting repair, defective products, returned goods, and scrapped products.

[0003] For ordinary motors with relatively simple structures, the end caps are usually easy to remove. However, for certain specific applications (such as aerators in aquaculture), which require heavy motors and high levels of sealing, removing the end caps becomes exceptionally difficult. During the production and assembly of these motors, to ensure their waterproof and dustproof sealing performance, sealant is typically applied simultaneously between the mating surfaces of the housing and the upper and lower end caps, and sealing rings are installed, followed by multiple screws for tightening. This combination of multiple seals and high-strength fastening creates an extremely tight connection between the end caps and the housing, resulting in significant resistance to disassembly.

[0004] Currently, the common traditional method for disassembling the end cover of this type of sealed motor is to first remove all the screws that fix the end cover, and then use tools such as hammers to repeatedly tap the edge of the end cover in an attempt to loosen it and eventually separate it through impact.

[0005] In the production process of electric motors, it is necessary to disassemble, repair, or maintain certain products (products awaiting repair, defective products, returned products, scrapped products, etc.). This requires separating the motor end cover from the motor body to facilitate the repair and maintenance of internal components. However, this method is time-consuming and labor-intensive, resulting in high worker workload, low efficiency, and a high risk of product damage.

[0006] To address the aforementioned problems, several motor end-cover removal devices have emerged in the prior art. For example, a motor end-cover removal device with patent number CN215498684U is described. This device features a rotatable fixing component designed to facilitate clamping and securing the motor body, and claims to be adaptable to different motor sizes and adjustable motor orientation. However, this device relies on clamping and securing the motor housing (typically cylindrical). To overcome the significant separation resistance during disassembly and prevent the motor from slipping during operation, the device requires a considerable clamping force. This strong clamping force can easily cause indentations, deformation, or even cracks in the relatively thin motor housing (especially non-metallic housings or painted surfaces), resulting in irreversible damage to the motor body.

[0007] Therefore, there is an urgent need to develop a new type of motor end cap removal device that can effectively overcome the huge disassembly resistance generated by the tight sealing connection, and safely, efficiently and without damage separate the end cap from the motor body without applying destructive clamping force to the motor housing. This would significantly reduce the labor intensity of workers, improve work efficiency, and protect the integrity of the product to the greatest extent. Utility Model Content

[0025] Furthermore, the top pressure groove plate is provided with a rotating stop block, and the rotating stop block can be rotatably set at the edge of the top pressure groove plate through a connecting sleeve.

[0026] Preferably, the rotating stop is rotatably and vertically positioned at the edge of the top pressure groove plate to abut against the edges of the support groove plate and the disassembly groove plate, preventing the support groove plate and the disassembly groove plate from extending outwards.

[0027] Furthermore, a spring assembly for resetting is provided between the expansion and unloading component and the base. The spring assembly includes a spring sleeve and a limiting rod.

[0035] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0036] ① The upper end cover of the motor is placed against the upper end of the support groove plate, and the lower end cover of the motor is placed against the lower end of the disassembly groove plate. When the pressure head of the pressure equipment moves the pressure cover downward, it pushes the guide column downward as well. The guide column pushes the pressure groove plate and the disassembly groove plate downward together. As the disassembly groove plate moves downward, the pushing surface of the disassembly groove plate pushes the lower end cover of the motor downward, thereby separating the end cover from the housing, thus creating a precise and controllable "tearing" action. The lower end cover of the motor is pushed downward, while the upper end cover is "blocked" by the fixed support groove plate, forcing the mating surfaces of the motor end cover and the housing to be separated by force in the vertical direction simultaneously. This bidirectional synchronous separation mechanism is more effective, smoother, and less likely to damage the end cover or housing than prying or impacting from only one direction. It can also be applied to end covers with interference fits or severe corrosion and adhesion.

[0037] ② The first support plate, the top pressure groove plate, and the first disassembly plate are fixed on the base. The second support plate and the second disassembly plate are designed to slide with the second movable column and the top pressure groove hole (first top pressure groove hole), so that the second support plate and the second disassembly plate can move laterally relative to the first support plate and the first disassembly plate. This increases the capacity of the groove plate and the disassembly groove plate. The capacity of the groove plate and the disassembly groove plate can be flexibly adjusted according to the actual size of the motor end cover, which significantly improves the compatibility with motors of different specifications without the need to replace the entire set of fixtures or tooling.

[0038] ③ A linear guiding mechanism is adopted, which uses guide columns (first connecting column and second movable column) in conjunction with guide sleeves, to ensure that the top pressure plate and disassembly plate can move smoothly and accurately in a straight line under the drive of the pressure plate, so as to carry out expansion or ejection operations.

[0039] ④ The spring assembly reset design (such as limit rod and spring sleeve) can automatically or assistedly reset the disassembled parts after the disassembly action is completed, making it convenient for the next operation.

[0040] ⑤ The rotating stop can be rotated to a vertical position when needed, abutting against the edges of the support slot plate and the disassembly slot plate, effectively preventing these critical moving parts from accidentally slipping or excessively extending during operation or reset, reducing the risk of workpiece splashing or parts going out of control, and improving operational safety.

[0066] Example 1

[0067] like Figure 1-20 As shown, this embodiment discloses a disassembly device for a motor end cover, including a pressure cover, an expansion and unloading component, and a base; the pressure cover is disposed on the top of the expansion and unloading component, and the expansion and unloading component is connected to the base;

[0068] The expansion and unloading components include a support groove plate 1 for abutting the upper end cover of the motor, a top pressure groove plate 2, and a disassembly groove plate 3 for abutting the lower end cover of the motor. The support groove plate 1 is detachably connected to the base. The top pressure groove plate 2 and the disassembly groove plate 3 are installed at the bottom of the support groove plate 1 and can move away from the support groove plate 1.

[0069] The support groove plate 1 is provided with a guide sleeve 4. The pressure plate passes through the guide sleeve 4 via a guide post 5 and connects the top pressure groove plate 2 and the disassembly groove plate 3, which is used to drive the top pressure groove plate 2 and the disassembly groove plate 3 to move away from the support groove plate 1.

[0070] The support groove plate 1 includes a first support plate 101 and a second support plate 102.

[0071] The top pressure groove plate 2 is provided with a first top pressure groove hole 201.

[0072] The disassembly plate 3 includes a first disassembly plate 301 and a second disassembly plate 302.

[0073] The guide post 5 includes a first connecting post 501 and a second movable post 502.

[0074] The top pressure groove plate 2 and the first disassembly plate 301 are located below the first support plate 101 and can be movably passed through the guide sleeve 4 of the first support plate 101 via the first connecting column 501;

[0075] The top pressure groove plate 2 and the second disassembly plate 302 are located below the second support plate 102, and the first top pressure groove hole 201 is movably disposed in the guide post 5 of the second support plate 102 through the second movable post 502;

[0076] The second movable column 502 is disposed in the first top pressure slot 201 and can move along the length direction of the first top pressure slot 201.

[0077] Initially, the second support plate 102 and the second disassembly plate 302 are moved outward (away from the first support plate 101 and the first disassembly plate 301) to a suitable position to form an open space; then, the motor with the screws removed is placed into the device, the support groove plate 1 is inserted into the lower edge of the upper end cover of the motor, and then the second support plate 102 and the second disassembly plate 302 are moved inward (closer to the first support plate 101 and the first disassembly plate 301) until they are completely in contact with the motor end cover, so that the disassembly groove plate 3 is inserted into the lower edge of the lower end cover of the motor, and then the rotating stop 7 is automatically rotated down to a vertical position (lowest point) by gravity, locking the edges of the left and right support plates (first support plate 101 and second support plate 102) / disassembly plates (first disassembly plate 301 and second disassembly plate 302);

[0078] When separation begins, the pressure device is activated, which drives the pressure cap to press down, thereby pushing the four guide pillars 5 to move down synchronously. The guide pillars 5 push the top pressure groove plate 2 and the disassembly groove plate 3 to move down as a whole. The pushing surface of the disassembly groove plate 3 abuts against the lower end cover of the motor and applies downward pressure. The upper end cover of the motor is fixedly constrained by the support groove plate 1, forming a reaction force fulcrum, so that the end cover and the joint surface of the machine housing are pushed open synchronously from both the top and bottom.

[0079] After completion, the pressure equipment is retrieved, the pressure equipment drives the pressure cap to rise, causing the guide post 5 to move upward, and the spring assembly releases its stored energy to push the top pressure groove plate 2 and the disassembly groove plate 3 to move upward and reset to fit the support groove plate 1; then manually rotate the stop block 7 to the horizontal position (release the limit), push the second support plate 102 and the second disassembly plate 302 to the right, so that the disassembly device returns to the open state, and then the separated motor is taken out from the opening.

[0080] Specifically, the second support plate 102 and the second disassembly plate 302 are moved outward (away from the first support plate 101 and the first disassembly plate 301) to a suitable position to form an open space that allows the motor to be inserted without obstruction, thereby improving the loading efficiency. The two support plates / disassembly plates can be slidably adjusted to accommodate end caps of different diameters (without the need to replace parts).

[0081] This device solves the alignment problem of traditional clamps through intelligent locking verification of gravity blocks. It achieves non-destructive separation of end caps by using rigid ejection of guide post 5 and bidirectional constraint model. Combined with automatic spring reset and sliding modular design, it forms an efficient closed-loop process of "loading-locking-disassembly-reset", which is particularly suitable for batch disassembly and maintenance of motors.

[0082] As one specific embodiment, the first disassembly plate 301 is detachably connected to the base, the second disassembly plate 302 is provided with a disassembly hole 303, and the top pressure groove plate 2 is provided with a second top pressure groove hole 202. The disassembly hole 303 is movably connected to the second top pressure groove hole 202 by a movable bolt 6.

[0083] The second support plate 102 also includes a support slot 103, which is movably connected to the base by bolts.

[0084] During the debugging process, loosen the bolts in the support slot 103, slide the second support plate 102 laterally, and move the second disassembly plate 302; adjust the position of the movable bolt 6 in the second top pressure slot 202 and the disassembly hole 303, lock the relative distance between the second disassembly plate 302 and the top pressure slot 2, and match the end cap size.

[0085] When the motor is placed in the special configuration, the second support plate 102 and the second disassembly plate 302 are pushed to slide and close to the left. The first disassembly plate 301 is rigidly fixed to the base by bolts to form the main support. The movable bolt 6 slides in the second top pressure slot 202, allowing the second disassembly plate 302 to flexibly follow and close.

[0086] When the guide post 5 is pressed down to disassemble, the first disassembly plate 301 remains fixed, providing a fulcrum for the reaction force; the top pressure groove plate 2 pushes the movable bolt 6 through the second top pressure groove hole 202, driving the second disassembly plate 302 to move down synchronously to eject the end cover.

[0087] During reset, the spring pushes the top pressure groove plate 2 upward, and the movable bolt 6 slides along the second top pressure groove hole 202, driving the second disassembly plate 302 to reset; the second support plate assembly can be moved out laterally by loosening the bolt.

[0088] This embodiment, through a rigid-flexible force-bearing structure and a multi-level adjustment mechanism, significantly improves equipment compatibility and ease of maintenance while ensuring disassembly stability.

[0089] As one specific embodiment, the top pressure groove plate 2 is provided with a rotating stop 7, and the rotating stop 7 can be rotatably set at the edge of the top pressure groove plate 2 through the connecting sleeve.

[0090] When installing the motor end cover, keep the rotating stop 7 in a horizontally retracted position (parallel to the top pressure slot plate 2) to avoid interfering with the insertion of the motor or the sliding of the support plate.

[0091] Then, the support plate 1 and the disassembly plate 3 are retracted, and the rotating block 7 automatically rotates to a vertical position under the action of gravity, and gets into the gap between the edges of the left and right support plates / disassembly plates. The vertical block 7 forms a physical limiting barrier to prevent the support plate 1 and the disassembly plate 3 from shifting laterally or coming out under the action of the pushing force.

[0092] After disassembly, manually rotate the stop 7 to a horizontal position to release the lock on the moving parts, allowing the second support plate 102 to move to the right and open. The rotating stop 7 uses a simple mechanical structure of gravity drive + manual intervention to achieve the triple functions of locking verification, dynamic protection and quick unlocking.

[0093] Example 2

[0094] like Figure 1-20 As shown, this embodiment discloses a disassembly device for a motor end cover.

[0095] In one specific embodiment, a spring assembly for resetting is provided between the expansion component and the base. The spring assembly includes a spring sleeve 8 and a limiting rod 9. The limiting rod 9 is disposed between the expansion component and the base, and the spring sleeve 8 is sleeved on the outside of the limiting rod 9 and abuts against the expansion component and the base.

[0096] The disassembly slot plate 3 is also provided with a disassembly limiting hole 304, and the top pressing slot plate 2 is provided with a top pressing limiting hole 203. The limiting rod 9 is detachably mounted on the base. The top of the limiting rod 9 passes through the disassembly limiting hole 304 and the top pressing limiting hole 203 and abuts against the support slot plate 1. The spring sleeve 8 is sleeved on the outside of the limiting rod 9 and abuts against the disassembly slot plate 3 and the base.

[0097] During disassembly, the top pressure groove plate 2 and the disassembly groove plate 3 move downwards, and the spring sleeve 8 is compressed between the disassembly groove plate 3 and the base. The top of the limiting rod 9 passes through the disassembly limiting hole 304 / top pressure limiting hole 203 and abuts against the support groove plate 1. When the disassembly groove plate 3 moves downwards, it compresses the spring sleeve 8.

[0098] When disassembly is complete, the pressure device is withdrawn and moved upward, the guide column 5 releases the downward pressure and moves upward, and the spring sleeve 8 pushes the disassembly slot plate 3 upward, causing the top pressure slot plate 2 to reset synchronously, until the disassembly slot plate 3 fits against the bottom of the support slot plate 1.

[0099] Specifically, the bottom of the limit rod 9 is detachably mounted on the base via a nut, allowing the limit rod 9 and spring sleeve 8 to be pulled out as a whole, making it possible to replace the spring or clean in just 1 minute.

[0100] Example 3

[0103] During operation, the pressure device drives the pressure cap to move downward, and the connecting column 11 rigidly transmits the driving force to the upper mold cover 12. The slot of the upper mold cover 12 precisely presses against the top of the four guide columns 5, thereby driving the guide columns 5 to move downward synchronously, thus achieving precise force transmission.

[0104] As one specific embodiment, the base includes a base plate 13 and a side plate 14, with the side plate 14 being detachably mounted on the top of the base plate 13;

[0105] The side plate 14 is also provided with a connection hole, through which the first support plate 101, the top pressure groove plate 2 and the first disassembly plate 301 can be detachably connected to the top of the side plate 14;

[0106] The support slot 103 is bolted to the upper part of the movable side plate 14 of the second support plate 102 and the second disassembly plate 302.

[0107] During assembly, the side plate 14 and the base plate 13 are connected by bolts. During replacement, the side plate 14 and all the expansion parts above it can be removed as a whole, and the side plate assembly adapted to another motor specification can be quickly replaced. During targeted maintenance, the damaged side plate 1 can be removed and replaced by simply removing the connecting bolts on one side, avoiding the need to disassemble the whole machine.
