[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] (1) The riveting tooling of the motor casing and the end cover, when the end cover is placed on the base, the gravity of the end cover will push the force-bearing plate and the movable plate downward, and the movable plate will squeeze the gas inside the fixed frame into the inside of the sealing frame. When the air pressure inside the sealing frame increases, it will push the arc block to move. The arc block will move and contact the port of the end cover, so that the arc block will push the top of the end cover to be in a parallel state, preventing the top of the end cover from tilting and affecting the riveting effect with the casing.

[0017] (2) The riveting tooling of the motor housing and the end cover is to place the end cover in front of the base. The end cover will slide on the surface of the elastic plate, so that the end cover will drive the rotating wheel to rotate. When the rotating wheel rotates, it will drive the protrusion to rotate. When the protrusion rotates, it will push the elastic rod and the transmission rod, so that the impact plate will intermittently knock on the bottom of the end cover to prevent foreign matter from adhering to the surface of the end cover and affecting the balance effect of the end cover inside the placement groove.

[0018] (3) The riveting tooling of the motor housing and the end cover, when the end cover is on the elastic plate, the elastic plate will push the end cover to rotate, and the contact wheel will make the end cover easily rotate on the elastic plate. When the elastic telescopic block is inserted into the riveting position of the end cover, the riveting position of the end cover can be accurately positioned and restricted. At the same time, the elastic telescopic block can accurately position the riveting position of the housing, so that when the end cover and the housing are overlapped, the riveting positions will be accurately aligned together, thereby improving the efficiency of riveting the end cover and the housing.

[0019] (4) The riveting tooling of the motor housing and the end cover can clamp the housing through the circular plate and the arc plate, so that the housing can be inside the end cover, which is convenient for installing the housing on the end cover. At the same time, when the housing is installed on the circular plate, it will push the trapezoidal block and the linkage rod to move, so that the trapezoidal block will drive the linkage rod and the moving plate to move according to the diameter of the housing. When the moving plate contacts the end cover, a circle will be generated. If the moving plate moves too much or too little, the pressing rod cannot completely press the detection switch in. The contact switch can be used to determine whether the upper and lower positions of the housing and the end cover are aligned, to prevent the housing and the end cover from being misaligned and affecting the riveting.

A force-bearing plate 57 is fixedly installed on the top of the movable plate 56, and the fixed frame 55 is connected to the inside of the sealing frame 51 through a pipeline; wherein, the removing device includes an arc plate 61 and a knocking assembly, the arc plate 61 is fixedly installed on the top of the arc block 54, and the knocking assembly is arranged on the surface of the arc plate 61, and the positioning device includes a hydraulic device 81 and a clamping assembly, the hydraulic device 81 is fixedly installed on the top of the support frame 2, and the clamping assembly is arranged on the surface of the hydraulic device 81, and the increase in air pressure inside the sealing frame 51 will push the sealing plate 52 and the fixing rod 53 to move downward, and the movement of the fixing rod 53 will drive the arc block 54 to move, and when the arc block 54 moves, the arc surface at the bottom of the arc block 54 will push the top of the end cover to be in a parallel state, so as to prevent the top of the end cover from tilting and affecting the riveting effect with the casing.

[0033] A No. 1 spring piece is arranged between the sealing plate 52 and the sealing frame 51, a No. 2 spring piece is arranged between the movable plate 56 and the fixed frame 55, and a placement groove is opened on the top of the base 1, through which the end cover is conveniently positioned, and the elastic force of the No. 2 spring piece can drive the movable plate 56 to reset.

[0034] The knocking assembly includes an elastic plate 62, which is fixedly mounted on the top of the arc plate 61. A rotating wheel 63 is rotatably mounted on the surface of the elastic plate 62. A protrusion 67 is fixedly mounted on the surface of the rotating wheel 63. A striking plate 64 is rotatably mounted on the surface of the elastic plate 62. A transmission rod 65 is fixedly mounted on the surface of the striking plate 64. An elastic rod 66 is fixedly mounted on the end of the transmission rod 65 away from the striking plate 64. When the end cover moves on the elastic plate 62, the rotating wheel 63 is driven to rotate. When the protrusion 67 rotates, it contacts the elastic rod 66, so that when the protrusion 67 rotates, it pushes the elastic rod 66 to move. When the elastic rod 66 moves, it pulls the transmission rod 65 to move. When the transmission rod 65 moves, it pulls the striking plate 64 to rotate. When the striking plate 64 rotates, it strikes the end cover. When the end cover is struck by the striking plate 64, it will vibrate, so as to prevent foreign matter from adhering to the surface of the end cover, which will affect the balance effect of the end cover inside the placement groove.

[0035] A torsion spring is provided between the impact plate 64 and the elastic plate 62 , and the protrusion 67 is in contact with the elastic rod 66 , so that the impact plate 64 can be driven to reset by the torsion spring.

[0036] A circular groove is provided on the surface of the rotating wheel 63, and a rotating device is provided on the surface of the rotating wheel 63. The rotating device includes a mounting plate 71 fixedly installed inside the circular groove, a contact wheel 72 rotatably installed on the surface of the mounting plate 71, and an elastic telescopic block 73 fixedly installed on the surface of the mounting plate 71, and the free end of the elastic telescopic block 73 is arc-shaped. When the cover rotates, it will drive the contact wheel 72 to rotate. When the end cover rotates, the elastic telescopic block 73 will be inserted into the rivet of the end cover, which can position the end cover, so that the riveting position of the end cover can be accurately positioned and limited. At the same time, the elastic telescopic block 73 can accurately position the riveting position of the casing, so that when the end cover and the casing overlap, the riveting positions will be accurately aligned together, thereby improving the riveting efficiency of the end cover and the casing.

[0037] The free end of the elastic expansion block 73 is arc-shaped, and the arc-shaped design ensures that the elastic expansion block 73 will not affect the effect of detaching from the riveting position.

[0038] The locking assembly includes a circular plate 82, which is fixedly installed on the output end of the hydraulic device 81. A sliding rod 83 is slidably sleeved on the top of the circular plate 82, and an arc-shaped clamping plate 84 is fixedly installed on the bottom of the sliding rod 83. A bending rod 85 is fixedly installed on the top of the support frame 2. A spring is arranged between the sliding rod 83 and the circular plate 82. After the sliding rod 83 is separated from the bending rod 85, the arc-shaped clamping plate 84 will clamp the casing, making it convenient to clamp the casing.

[0039] A trapezoidal block 86 is slidably installed at the bottom of the circular plate 82, a linkage rod 87 is fixedly installed at the bottom of the trapezoidal block 86, a moving plate 88 is slidably installed at the bottom of the linkage rod 87, a transverse plate 91 is fixedly installed on the surface of the linkage rod 87, a detection switch 93 is fixedly installed at the bottom of the transverse plate 91, and a pressing rod 92 is fixedly installed on the top of the moving plate 88. When the hydraulic device 81 drives the circular plate 82 and the casing to move downward, the surface of the moving plate 88 will contact the end cover, so that the moving plate 88 will drive the pressing rod 92 to move when it moves. When the positions of the casing and the end cover are aligned, the position of the moving plate 88 can make the pressing rod 92 contact with the detection switch 93 after moving, so as to press the detection switch. The moving distance of the moving plate 88 makes the pressing rod 92 just press the detection switch 93. When the positions of the casing and the end cover are offset, the pressing rod 92 will not be able to press the detection switch 93, so that it can be judged whether the casing and the end cover are aligned, to prevent the casing and the end cover from not being aligned and affecting the riveting.

[0040] A reset spring is arranged between the trapezoidal block 86 and the circular plate 82, an elastic member is arranged between the movable plate 88 and the linkage rod 87, and the left side of the movable plate 88 is arranged as an inclined surface, which facilitates the movable plate 88 to move, and the movable plate 88 can be driven to reset by the elastic member.

[0041] When working, the end cap is first placed inside the placement groove. Before the end cap enters the placement groove, the end cap will first contact the elastic plate 62. When the end cap moves on the surface of the elastic plate 62, it will push the elastic plate 62 to deform. At the same time, the end cap is rotated on the elastic plate 62. When the end cap rotates, it will drive the contact wheel 72 to rotate. When the end cap rotates, the elastic telescopic block 73 will be inserted into the riveting position of the end cap, which can play a positioning effect on the end cap.

[0042] Then, when the end cover is pushed downward, the end cover will move downward on the surface of the elastic plate 62. When the end cover moves downward, it will drive the rotating wheel 63 to rotate. When the rotating wheel 63 rotates, it will drive the protrusion 67 to rotate. When the protrusion 67 rotates, it will contact the elastic rod 66, so that when the protrusion 67 rotates, it will push the elastic rod 66 to move. When the elastic rod 66 moves, it will pull the transmission rod 65 to move. When the transmission rod 65 moves, it will pull the impact plate 64 to rotate. When the impact plate 64 rotates, it will hit the end cover. When the end cover is hit by the impact plate 64, it will vibrate, which can improve the effect of dust removal on the surface of the end cover.

[0043] After the end cover is detached from the elastic plate 62, it will enter the interior of the placement groove. When the end cover enters the interior of the placement groove, it will push the force-bearing plate 57 to move downward. When the force-bearing plate 57 moves downward, it will drive the movable plate 56 to move downward. When the movable plate 56 moves downward, it will squeeze the gas inside the fixed frame 55. The fixed frame 55 and the sealing frame 51 are connected through a pipeline, so that the gas inside the fixed frame 55 will enter the interior of the sealing frame 51 through the pipeline. The air pressure inside the sealing frame 51 increases and will push the sealing plate 52 and the fixing rod 53 to move. When the fixing rod 53 moves, it will drive the arc block 54 to move. When the arc block 54 moves, the arc surface at the bottom of the arc block 54 will push the top of the end cover to be in a parallel state.

[0044] Then, the casing is inserted into the circular plate 82, so that the riveted position on the casing is aligned with the elastic telescopic block 73, and then the circular plate 82 is driven downward by the hydraulic device 81, so that the slide bar 83 is separated from the bending rod 85, and the elastic force of the spring pushes the slide bar 83 and the arc clamping plate 84 to move in the direction of the casing, and the arc clamping plate 84 clamps the casing. At the same time, when the casing is inserted into the circular plate 82, the inclined surface of the trapezoidal block 86 pushes the trapezoidal block 86 to move, and the trapezoidal block 86 will move. When the movable linkage rod 87 and the movable plate 88 move, and the hydraulic device 81 drives the circular plate 82 and the casing to move downward, the surface of the movable plate 88 will contact the end cover, so that the movement of the movable plate 88 will drive the pressing rod 92 to move. When the casing and the end cover are aligned, the moving distance of the movable plate 88 is sufficient to make the pressing rod 92 press the detection switch 93. When the casing and the end cover are offset, the pressing rod 92 will not be able to press the detection switch 93, so that it can be judged whether the casing and the end cover are aligned.
