Description

Technical Field

[0001] This invention relates to a dust cover mounting device for an electric motor housing. Background Technology

[0002] Because motors are prone to drawing in dust and impurities during use, which can affect their performance, dust covers are usually installed on the surface of the motor housing to prevent dust from entering when the motor draws in air, thus ensuring the safe use of the motor's stator and rotor.

[0003] Currently, dust covers on the casing are typically installed manually by workers who press and snap them together. This not only results in high labor costs but also poor installation efficiency. Prolonged pressing and installation can easily cause hand fatigue for workers, affecting subsequent installation efficiency. Furthermore, since dust covers are generally made of hard plastic casting, their surfaces may have protruding burrs, making it difficult for workers to press and snap them onto the casing. This further increases the difficulty of installation and raises the assembly and production costs of the dust cover and casing. Summary of the Invention

[0004] This invention mainly addresses the technical problems existing in the prior art, thereby providing a motor housing dust cover installation device that facilitates the automatic assembly of dust covers on the surface of the housing, effectively improves the installation efficiency of dust covers, and reduces the labor cost of dust cover installation.

[0005] This invention relates to a dust cover installation device for a motor housing, comprising a base plate and a top plate, and a dust cover storage mechanism, a dust cover pressing mechanism, and a motor housing pressing mechanism arranged sequentially from bottom to top between the base plate and the top plate. The motor housing pressing mechanism includes a first lifting plate and a first cylinder connected to the top plate for driving the first lifting plate to move. A pressing mold is movably connected below the first lifting plate. The dust cover storage mechanism includes a guide seat for placing the dust cover, a lower module movably disposed inside the guide seat, and a fourth cylinder disposed below the guide seat for driving the lower module to rise and fall. The dust cover pressing mechanism includes a second lifting plate and a fifth cylinder connected to the base plate for driving the second lifting plate to move. A pressing edge clamp for pressing the edge of the dust cover is slidably disposed on the surface of the second lifting plate. A third cylinder for driving the pressing edge clamp to move is connected to the side of the second lifting plate, and the pressing edge clamp is sleeved outside the guide seat.

[0006] Preferably, an upper slider is slidably disposed on the surface of the first lifting plate, and a second cylinder for driving the upper slider to slide is connected to the side of the first lifting plate. An inclined groove is disposed inside the upper slider, and a connecting shaft passing through the upper slider is movably disposed in the center of the inclined groove. One end of the connecting shaft is connected to the upper mold, and the other end of the connecting shaft is movably connected to a roller, which is movably connected in the inclined groove. This allows the second cylinder to drive the upper slider to slide on the first lifting plate, thereby allowing the roller to rotate inside the inclined groove in the center of the upper slider. The connecting shaft is driven to rise and fall by the different heights at both ends of the inclined groove, so that the connecting shaft can control the upper mold to perform pressing. The inclined groove is an elongated hole and is set at an angle with the horizontal plane.

[0007] Preferably, the upper slider is provided with a connecting sleeve. One side of the connecting sleeve is connected to the first lifting plate, and the other side of the connecting sleeve is connected to the piston rod of the first cylinder. This allows the upper slider to slide stably under the guidance of the connecting sleeve, avoiding the problem of deviation during the sliding of the upper slider. The first cylinder can drive the first lifting plate to move up and down through the connecting sleeve.

[0008] Preferably, the guide seat has two or more sliding holes in the center for placing the dust cover. The lower module is slidably disposed inside the sliding holes, and a groove is provided above the lower module for pressing the outer edge of the dust cover. A fixing plate is connected to the lower part of the lower module, and a rotating wheel is movably connected below the fixing plate, so that the lower module can move up and down inside the sliding holes. The movement of the fixing plate drives the entire lower module to move up and down, so as to place the dust cover on the sliding hole in the center of the guide seat and limit the dust cover through the sliding hole. At the same time, the groove above the lower module facilitates pressing the outer side of the dust cover into the motor housing, and the number of lower modules corresponds to the number of dust cover positions.

[0009] Preferably, a lower slider is slidably disposed above the base plate, and a fourth cylinder for driving the lower slider to slide is connected to the side of the base plate. A rotating wheel below the fixed plate is located on the upper surface of the lower slider and cooperates with the lower slider. An angle is set between the upper surface of the lower slider and the horizontal plane, and the rotating wheel drives the fixed plate to rise and fall at different height positions on the upper surface of the lower slider. The fourth cylinder can drive the lower slider to slide laterally. A track for smooth movement is provided on the lower surface of the lower slider, and a guide groove for guiding the rotating wheel is provided on the upper surface of the lower slider.

[0010] Preferably, there are two or more pressure hoops, and the pressure hoops are arranged around the center to form a hoop hole. The pressure hoops are slidably arranged on the surface of the second lifting plate, and a third cylinder is connected to the side of each pressure hoop, so that the third cylinder can drive the pressure hoops to slide on the surface of the second lifting plate. The formation of the hoop hole is controlled by the convergence and separation of the pressure hoops. There are two pressure hoops, which are respectively located on both sides of the upper surface of the second lifting plate.

[0011] Preferably, a guide post is provided above the guide seat. The guide post is embedded in the hoop hole formed by the pressure edge hoop and is fitted with a gap between the hoop hole and the guide post above the guide seat can be embedded in the hoop hole formed by the pressure edge hoop. This allows the pressure edge hoop to press the outer edge of the dust cover located in the sliding hole, making it easier for one end of the dust cover to be lifted up and embedded into the motor housing.

[0012] Preferably, a limiting block connected to the second lifting plate is provided above the pressing edge hoop, and the pressing edge hoop is slidably disposed below the limiting block, so that the sliding movement of the pressing edge hoop can be limited and guided by the limiting block, so that the pressing edge hoop can slide smoothly.

[0013] Preferably, a shaft connects the bottom plate and the top plate, and the first lifting plate and the second lifting plate are slidably connected at the center of the shaft. The first lifting plate is located above the second lifting plate, so that the lifting and lowering movement of the first lifting plate and the second lifting plate can be guided by the shaft, which facilitates the smooth lifting and lowering movement of the first lifting plate and the second lifting plate between the top plate and the bottom plate.

[0014] Preferably, a limiting post is connected above the base plate, with the upper end of the limiting post located below the first lifting plate. A support block is detachably connected to the end of the limiting post, so that the limiting post restricts the lifting height of the first lifting plate, preventing the first cylinder from driving the first lifting plate to descend too far and hitting the second lifting plate or the motor housing. The support block allows the user to control and adjust the height that the first lifting plate can descend, and also allows the manufacturer to select and adjust the support block of the appropriate height according to the different height specifications of the motor housing. The limiting post is located outside the second lifting plate.

[0015] The beneficial effects of this invention are as follows: the lower slider inside the guide seat is used to place and limit the dust cover, and then the descent of the second lifting plate drives the pressure edge hoop to press one side of the dust cover. The descent of the first lifting plate allows the lower pressing mold to approach the guide seat, so that the lower pressing mold can be driven by the second cylinder to press the motor housing, making it easier for the dust cover to be embedded into the motor housing. The segmented descent of the lower pressing mold makes it easier to control the pressing intensity of the motor housing, avoiding excessive pressure that would cause the motor housing to come into contact with the dust cover and cause damage to the motor housing or the dust cover, effectively ensuring the integrity of the dust cover and the motor housing after assembly.

[0016] Simultaneously, the lifting of the lower module driven by the fourth cylinder controls the dust cover to be fully engaged with the motor housing. This allows the device to automatically engage and fix the dust cover to the surface of the motor housing, effectively reducing the labor intensity of workers manually pressing the dust cover into the motor housing. This greatly improves the assembly efficiency of the motor housing and the dust cover, and effectively reduces the labor cost required for assembling the dust cover and the motor housing. It also improves the assembly efficiency and installation convenience of the dust cover, while effectively avoiding problems such as omissions, misalignments, and incomplete engagement that may occur due to human negligence during assembly, ensuring the stability and firmness of the dust cover and the motor housing after assembly.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0028] like Figures 1 to 8 The diagram shows a motor housing dust cover mounting device, comprising a base plate 7 and a top plate 71, and a dust cover storage mechanism (not labeled), a dust cover pressing mechanism (not labeled), and a motor housing pressing mechanism (not labeled) arranged sequentially from bottom to top between the base plate 7 and the top plate 71. The motor housing pressing mechanism includes a first lifting plate 11 and a first cylinder 1 connected to the top plate 71 for driving the first lifting plate 11 to move. A pressing mold 22 is movably connected below the first lifting plate 11. The dust cover storage mechanism includes a guide for placing the dust cover 81. The guide seat 61, the lower module 62 movably disposed inside the guide seat 61, and the fourth cylinder 4 disposed below the guide seat 61 for driving the lower module 62 to rise and fall. The dust cover pressing mechanism includes a second lifting plate 51 and a fifth cylinder 5 connected to the base plate 7 for driving the second lifting plate 51 to move. The surface of the second lifting plate 51 is slidably provided with a pressing edge hoop 31 for pressing the edge of the dust cover 81. A third cylinder 3 is connected to the side of the second lifting plate 51 for driving the pressing edge hoop 31 to move. The pressing edge hoop 31 is sleeved on the outside of the guide seat 61.

[0029] The first lifting plate 11 has an upper slider 21 slidably mounted on its surface, and a second cylinder 2 for driving the upper slider 21 to slide is connected to the side of the first lifting plate 11. The upper slider 21 has an inclined groove 211 inside, and a connecting shaft 23 is movably mounted through the center of the inclined groove 211. One end of the connecting shaft 23 is connected to the upper mold 22, and the other end of the connecting shaft 23 is movably connected to a roller 24. The roller 24 is movably connected inside the inclined groove 211, so that the second cylinder 2 can drive the upper slider 21 to slide on the first lifting plate 11, thereby allowing the roller 24 to rotate inside the inclined groove 211 in the center of the upper slider 21. The connecting shaft 23 is driven to rise and fall by the different heights at both ends of the inclined groove 211, so that the connecting shaft 23 can control the upper mold 22 to perform pressing. The inclined groove 211 is an elongated hole with an angle between it and the horizontal plane.

[0030] The upper slider 21 is provided with a connecting sleeve 12. One side of the connecting sleeve 12 is connected to the first lifting plate 11, and the other side of the connecting sleeve 12 is connected to the piston rod of the first cylinder 1. This allows the upper slider 21 to slide stably under the guidance of the connecting sleeve 12, avoiding the problem of deviation during the sliding of the upper slider 21. The first cylinder 1 can drive the first lifting plate 11 to move up and down through the connecting sleeve 12.

[0031] The guide seat 61 has two or more sliding holes 611 in the center for placing the dust cover 81. The lower module 62 is slidably disposed inside the sliding holes 611, and the upper part of the lower module 62 is provided with a groove 621 for pressing the outer side of the dust cover 81. A fixing plate 6 is connected to the lower part of the lower module 62, and a rotating wheel 63 is movably connected to the lower part of the fixing plate 6, so that the lower module 62 can move up and down inside the sliding holes 611 to place the dust cover 81 on the sliding hole 611 in the center of the guide seat 61 and limit the dust cover 81 through the sliding hole 611. At the same time, the groove 621 above the lower module 62 facilitates pressing the outer side of the dust cover 81 into the motor housing 8, and the number of positions of the lower module 62 corresponds to the number of positions of the dust cover 81.

[0032] A sliding block 41 is slidably mounted above the base plate 7. A fourth cylinder 4 for driving the sliding block 41 is connected to the side of the base plate 7. A rotating wheel 63 is located on the upper surface of the sliding block 41 and cooperates with the sliding block 41. An angle is set between the upper surface of the sliding block 41 and the horizontal plane. The rotating wheel 63 drives the fixed plate 6 to rise and fall at different heights on the upper surface of the sliding block 41. The fourth cylinder 4 can drive the sliding block 41 to slide laterally. A track (not labeled) for smooth movement is set on the lower surface of the sliding block 41, and a guide groove (not labeled) for guiding the rotating wheel 63 is set on the upper surface of the sliding block 41.

[0033] Two or more pressure bands 31 are provided, and a hoop hole 32 is formed in the center of the pressure bands 31. The pressure bands 31 are slidably disposed on the surface of the second lifting plate 51, and a third cylinder 3 is connected to the side of each pressure band 31, so that the third cylinder 3 can drive the pressure band 31 to slide on the surface of the second lifting plate 51. The formation of the hoop hole 32 is controlled by the convergence and separation of the pressure bands 31. Two pressure bands 31 are provided and are respectively located on both sides of the upper surface of the second lifting plate 51.

[0034] A guide post 612 is provided above the guide seat 61. The guide post 612 is embedded in the hoop hole 32 formed by the pressure edge hoop 31 and is in clearance fit with the hoop hole 32, so that the guide post 612 above the guide seat 61 can be embedded in the hoop hole 32 formed by the pressure edge hoop 31. This allows the pressure edge hoop 31 to press the outer edge of the dust cover 81 located in the sliding hole 611, making it easy for one end of the dust cover 81 to be lifted up and embedded into the motor housing 8.

[0035] A limiting block 311 connected to the second lifting plate 51 is provided above the pressing edge hoop 31. The pressing edge hoop 31 is slidably disposed below the limiting block 311, so that the sliding movement of the pressing edge hoop 31 can be limited and guided by the limiting block 311, so that the pressing edge hoop 31 can slide smoothly.

[0036] A shaft 73 connects the bottom plate 7 and the top plate 71. The first lifting plate 11 and the second lifting plate 51 are slidably connected in the center of the shaft 73. The first lifting plate 11 is located above the second lifting plate 51, so that the lifting and lowering movement of the first lifting plate 11 and the second lifting plate 51 can be guided by the shaft 73, which facilitates the smooth lifting and lowering movement of the first lifting plate 11 and the second lifting plate 51 between the top plate 71 and the bottom plate 7.

[0037] A limiting post 72 is connected above the base plate 7. The upper end of the limiting post 72 is located below the first lifting plate 11, and the end of the limiting post 72 is detachably connected to a support block (not labeled). This limits the lifting height of the first lifting plate 11 by the limiting post 72, preventing the first cylinder 1 from driving the first lifting plate 11 to descend too far and collide with the second lifting plate 51 or the motor housing 8. The support block allows the user to control and adjust the height that the first lifting plate 11 can descend. It also allows the manufacturer to select and adjust the support block of the appropriate height according to the different height specifications of the motor housing 8. The limiting post 72 is located outside the second lifting plate 51.

[0038] The first cylinder 1, the second cylinder 2, the third cylinder 3, the fourth cylinder 4, and the fifth cylinder 5 can be hydraulic cylinders such as air cylinders or oil cylinders, or other power sources with driving capabilities, such as motors.

[0039] When it is necessary to assemble the dust cover 81 and the motor housing 8 through the motor housing dust cover mounting device, first place the dust cover 81 on the guide seat 61 in the dust cover storage mechanism, and restrict the dust cover 81 by the guide post above the guide seat 61, that is, place the dust cover 81 above the sliding hole 611 on the upper surface of the guide post 612, and position the dust cover 81 by the sliding hole 611.

[0040] Then, the fifth cylinder 5 is started and drives the second lifting plate 51 to descend, so that the hoop hole 32 formed by the pressure band 31 is fitted onto the guide post 612 above the guide seat 61, so that the pressure band 31 on the surface of the second lifting plate 51 can be pressed against the outside of the dust cover 81, causing the inside of the dust cover 81 to lift up.

[0041] Next, the motor housing 8 is placed on top of the dust cover 81, so that one side of the dust cover 81 is embedded into the clip hole 82 on the surface of the motor housing 8 for installing the dust cover 81. Then, the first cylinder 1 is started, and the first lifting plate 11 is driven to descend through the connecting sleeve. The descent height of the first lifting plate 11 is limited by the limiting post 72, so that the upper pressing mold 22 below the first lifting plate 11 is just above the motor housing 8. The upper pressing mold 22 is just 2mm-3mm above the motor housing 8.

[0042] Then the second cylinder 2 drives the upper slider 21 to slide. Since the inclined groove 211 inside the upper slider 21 has an angle with the horizontal plane, the roller 24 at the upper end of the connecting shaft 23 is at different horizontal heights inside the inclined groove 211. The different heights of the roller 24 drive the connecting shaft 23 to rise and fall to control the lower pressing mold 22 to press the motor housing 8, so that one end of the dust cover 81 can be completely embedded in the card hole 82 on the surface of the motor housing 8, and the motor housing 8 can be restricted to the upper surface of the guide seat 61.

[0043] Then, the third cylinder 3 is activated and drives the pressure clamp 31 to open, allowing the pressure clamp 31 to release its pressure on the side of the dust cover 81. The fourth cylinder 4 is then activated, driving the lower slider 41 to slide. Since there is an angle between the upper surface of the lower slider 41 and the horizontal plane, the rotating wheel 63 below the fixing plate 6 rises and falls according to the different horizontal heights on the surface of the lower slider 41. This allows the lower slider 41 to be supported by the rotating wheel 63 to lift the fixing plate 6 and the lower module 62. This allows the outer side of the dust cover 81 located in the sliding hole 611 to be completely snapped into the motor housing 8 under the action of the lower module 62, completing the assembly of the dust cover 81 and the motor housing 8. The groove 621 of the lower module 62 facilitates pressing the outer side of the dust cover 81 into the motor housing 8.

[0044] After the dust cover 81 is assembled with the motor housing 8, the fourth cylinder 4 resets and drives the lower slider 41 to slide, causing the rotating wheel 63 and the fixed plate 6 connected to the rotating wheel 63 to descend, and simultaneously driving the lower module 61 connected to the fixed plate 6 to descend and reset; then the second cylinder 2 resets and drives the upper slider 21 to slide, causing the roller 24 at the upper end of the connecting shaft 23 to rise, and simultaneously driving the upper pressure mold 22 connected to the connecting shaft 23 to rise and reset; then the first cylinder 1 resets and lifts the first lifting plate 1 through the connecting sleeve 12. 1. This allows the upper pressure mold 22, which is connected to the first lifting plate 11 below, to move away from the motor housing 8. Then, the fifth cylinder 5 starts and drives the second lifting plate 51 to rise, and the third cylinder 3 starts and controls the pressure band 31 to reset and retract, so that the pressure band 31 surrounds to form the band hole 32. Then, the motor housing 8, which is placed above the guide seat 61 and assembled with the dust cover 81, can be taken out from it, and the preparation work for the subsequent pressing of the dust cover 81 and the motor housing 8 is completed.

[0045] The beneficial effects of this invention are as follows: the lower slider inside the guide seat is used to place and limit the dust cover, and then the descent of the second lifting plate drives the pressure edge hoop to press one side of the dust cover. The descent of the first lifting plate allows the lower pressing mold to approach the guide seat, so that the lower pressing mold can be driven by the second cylinder to press the motor housing, making it easier for the dust cover to be embedded into the motor housing. The segmented descent of the lower pressing mold makes it easier to control the pressing intensity of the motor housing, avoiding excessive pressure that would cause the motor housing to come into contact with the dust cover and cause damage to the motor housing or the dust cover, effectively ensuring the integrity of the dust cover and the motor housing after assembly.

[0046] Simultaneously, the lifting of the lower module driven by the fourth cylinder controls the dust cover to be fully engaged with the motor housing. This allows the device to automatically engage and fix the dust cover to the surface of the motor housing, effectively reducing the labor intensity of workers manually pressing the dust cover into the motor housing. This greatly improves the assembly efficiency of the motor housing and the dust cover, and effectively reduces the labor cost required for assembling the dust cover and the motor housing. It also improves the assembly efficiency and installation convenience of the dust cover, while effectively avoiding problems such as omissions, misalignments, and incomplete engagement that may occur due to human negligence during assembly, ensuring the stability and firmness of the dust cover and the motor housing after assembly.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
