Detailed Implementation

[0031] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1As shown, a swing arm assembly machine includes a base plate 1, a swing arm clamping and positioning mechanism 3, a ball pin seat riveting mechanism 4, a front bushing riveting mechanism 5, a rear bushing riveting mechanism 6, and a follower mechanism 7. The three follower mechanisms 7 are mounted on the base plate 1. The swing arm clamping and positioning mechanism 3 is mounted on the base plate 1 and is used to fix the swing arm 2. The ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 are respectively mounted on the corresponding follower mechanisms 7 and respectively rivet the ball pin seat, the front bushing, and the rear bushing onto the swing arm 2.

[0034] The ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 are respectively fed by a vibratory feeder or a robotic arm. These vibratory feeders or robotic arms are existing technologies and will not be described in detail here. Specifically, the swing arm 2 is positioned and clamped by the swing arm clamping and positioning mechanism 3. After the front bushing, rear bushing, or ball pin is fed, the corresponding ball pin seat riveting mechanism 4, front bushing riveting mechanism 5, or rear bushing riveting mechanism 6 is moved by the follower mechanism 7, causing the ball pin seat riveting mechanism 4, front bushing riveting mechanism 5, or rear bushing riveting mechanism 6 to move. The riveting mechanism 6 moves towards the mounting position of the swing arm 2. At the same time, the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, or the rear bushing riveting mechanism 6 clamps the swing arm 2. During clamping, the clamping angle is adjusted by the follower mechanism 7 to ensure the feeding and clamping status of the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, or the rear bushing riveting mechanism 6. Even a slight deviation of the swing arm 2 will affect the riveting accuracy of the front bushing, the rear bushing, or the ball pin. If the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 are fixedly connected, the slight angle cannot be adjusted, resulting in a loss of accuracy in the clamping and riveting state.

[0035] In another embodiment of the present invention, the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 each include a riveting cylinder 61, a first clamping plate 62, a second clamping plate 63, a guide slide rod 64, a fixing frame 65, a finger cylinder 66, and a shaft positioning block 68. The finger cylinder 66 is mounted on the fixing frame 65. The riveting cylinder 61 is mounted on the first clamping plate 62, and a pressure block is connected to the piston rod. The two ends of several guide slide rods 64 respectively pass through the first clamping plate 62 and the second clamping plate 63. Limit nuts are installed on the guide slide rods 64. Two shaft positioning blocks 68 are slidably connected to the guide slide rods 64 and are respectively connected to the two piston rods of the finger cylinder 66. A positioning material cavity is passed through the shaft positioning block 68. 611; A pressure ring 69 is installed on the second clamping plate 63 of the rear bushing riveting mechanism 6, and the first clamping plate 62 is connected to a shaft positioning block 68. One end of the pressure ring 69 is set in the positioning material hole cavity 611 of the shaft positioning block 68. The ball pin seat riveting mechanism 4 also includes a three-grip positioning cylinder 41, a positioning bullseye 42, and a telescopic column 43. A transition hole is opened on the second clamping plate 63 of the ball pin seat riveting mechanism 4. The three-grip positioning cylinder 41 is installed on the second clamping plate 63, and the second clamping plate 63 is connected to a shaft positioning block 68. The three telescopic columns 43 are connected to the piston rod of the three-grip positioning cylinder 41 and pass through the transition hole and the positioning material hole cavity 611 of the shaft positioning block 68. The positioning bullseye 42 is installed on the shaft positioning block 68.

[0036] Specifically, the front bushing, rear bushing, or ball pin is installed on the shaft positioning block 68 via a vibratory feeder or a robotic arm; when the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 are working, they all use finger cylinders 66 to drive the two shaft positioning blocks 68 to close and clamp the parts of the swing arm 2 where the front bushing, rear bushing, or ball pin is installed; however, the clamping and riveting actions of the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 are all different. Among them, the ball pin seat riveting mechanism 4 requires... In conjunction with the angle positioning and correction of the three-grip positioning cylinder 41, the three-grip positioning cylinder 41 drives the telescopic column 43, causing the telescopic column 43 to lock into the rocker arm 2 hole where the ball pin is installed. Then, the control finger cylinder 66 drives the two shaft positioning blocks 68 to loosen and tighten. The two shaft positioning blocks 68 then tighten, and the three-grip positioning cylinder 41 drives the telescopic column 43 to loosen the rocker arm 2 hole where the ball pin is installed. Thus, when the two shaft positioning blocks 68 are loosened, the three-grip positioning cylinder 41 drives the telescopic column 43 to lock into the rocker arm 2 hole where the ball pin is installed. Conversely, the three-grip positioning cylinder 41 drives the telescopic column 43 to loosen the rocker arm 2 hole for installing the ball pin. This cycle is repeated 2-3 times to align the rocker arm 2 hole for installing the ball pin with the relative axis of the ball pin seat. This facilitates the subsequent riveting cylinder 61 pushing the pressure block to press the ball pin seat into the rocker arm 2 hole for installing the ball pin. The positioning bullseye 42 keeps the ball pin seat stable in the positioning material cavity 611 of the mounting axis positioning block 68. When the front bushing riveting mechanism 5 is clamping and riveting, it clamps the bushing through the axis positioning block 68 and then pushes it through the riveting cylinder 61. The moving pressure block presses the front bushing inside the shaft positioning block 68 into the bushing. When the rear bushing riveting mechanism 6 is clamping and riveting, it clamps the bushing through the shaft positioning block 68, and then pushes the pressure block to act on the upper shaft positioning block 68 through the riveting cylinder 61. Under the reaction force of the riveting cylinder 61, the riveting cylinder 61 drives the first clamping plate 62 to pull the guide slide rod 64. The guide slide rod 64 pulls the second clamping plate 63, so that the pressure ring 69 on the second clamping plate 63 pushes the rear bushing inside the lower shaft positioning block 68 into the bushing.

[0037] In another embodiment of the present invention, a plurality of symmetrically arranged positioning bearings 67 are installed on the fixing frame 65 of the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6.

[0038] Specifically, when the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6 are driven to a designated position by the follower mechanism 7, they pre-correct and position themselves by pre-contacting the bushing through the symmetrical positioning bearings 67, so that the positioning material hole cavity 611 on the shaft positioning block 68 is aligned with the relative position of the bushing.

[0039] In another embodiment of the present invention, one end of the positioning material hole cavity 611 of the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6 is provided with an axial positioning chamfer 610.

[0040] Specifically, by setting the axial positioning angle 610 to guide the insertion angle of the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6, the positioning material cavity 611 of the axial positioning block 68 can be smoothly inserted into the bushing.

[0041] In another embodiment of the present invention, the angle between the inclined wall of the axial positioning chamfer 610 and the inner wall of the positioning material hole cavity 611 is 1 degree to 10 degrees.

[0042] Specifically, the smaller the axial positioning angle 610, the smoother the bushing can be inserted into the positioning material cavity 611 to avoid suffocation. It is best to perform surface polishing treatment to facilitate the overall correction of the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6.

[0043] In another embodiment of the present invention, the axial positioning block 68 of the front bushing riveting mechanism 5 is semi-circular.

[0044] Specifically, the shaft positioning block 68 is semi-circular, which facilitates the introduction of the front bushing into the positioning material cavity 611, reducing the structure of the feeding device and the use of pneumatic components.

[0045] In another embodiment of the present invention, the follower mechanism 7 includes a fixed base plate 71, a transmission screw 72, a transmission motor 73, a fixed frame 74, upper and lower swing blocks 75, left and right swing blocks 76, a swing step limiting rod 78, several bearing seats 77, and a slide. The fixed frame 74 is slidably connected to the fixed base plate 71. One end of the transmission screw 72 is connected to the fixed base plate 71 via the slide, and the other end is connected to the power rod of the transmission motor 73. The transmission motor 73 is mounted on the fixed frame 74. The upper and lower swing blocks 75 are movably connected to the fixed frame 74 via bearing seats 77. The left and right swing blocks 76 are rotatably connected to the upper and lower swing blocks 75. The left and right swing blocks 76 are movably connected to the corresponding ball pin seat riveting mechanism 4, front bushing riveting mechanism 5 and rear bushing riveting mechanism 6 via bearing seats 77. Two swing step limiting rods 78 are symmetrically arranged on the fixed frame 65 of the upper and lower swing blocks 75, the left and right swing blocks 76 and the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5 and the rear bushing riveting mechanism 6.

[0046] Specifically, the drive motor 73 drives the drive screw 72 to rotate, causing the fixed frame 74 to move. When the two axial positioning blocks 68 in the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 clamp the swing arm 2, the upper and lower swing blocks 75 and the left and right swing blocks 76 change their angles accordingly. At the same time, the relative positions of the upper and lower swing blocks 75 and the left and right swing blocks 76 will rotate for fine adjustment. The rotation angle and swing amplitude are small to ensure the clamping state of the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6, which is convenient for correcting the riveting accuracy. At the same time, after the clamping state is released, the positions of the ball pin seat riveting mechanism 4, the front bushing riveting mechanism 5, and the rear bushing riveting mechanism 6 will not change too much, which is convenient for the clamping position when the axial positioning block 68 is riveted next time. The swing floating step limit rod 78 limits the swing amplitude and rotation amplitude of the upper and lower swing blocks 75 and the left and right swing blocks 76 to avoid the swing and rotation amplitude being too large, which would cause the clamping position of the axial positioning block 68 to change.

[0047] In another embodiment of the present invention, an impact silicone block is installed on the pendulum step limiting rod 78.

[0048] Specifically, the impact of the silicone block prevents the pendulum step limit rod 78 from directly colliding with the upper and lower pendulum blocks 75 and the left and right pendulum blocks 76.

[0049] In another embodiment of the present invention, the swing arm clamping and positioning mechanism 3 includes a stepped positioning post 31 and a clamping device 32, both of which are mounted on the base plate 1. The clamping device 32 includes a clamping cylinder 33, a clamping pull post 34, a positioning post 35, a hinge plate 36, an adjusting inner inclined ring 38, a hinge pressure plate 310, an adjusting rod 311, a positioning bolt 312, and a spring. The clamping cylinder 33 and the positioning post 35 are respectively mounted on the upper and lower sides of the base plate 1. One end of the clamping pull post 34 is connected to the clamping cylinder 33. The force rod is connected to the base plate 1 and the positioning post 35 and connected to the hinge plate 36. The positioning post 35 has several clearance grooves 37 around the clamping pull post 34 near the end of the hinge plate 36. Several hinge pressure plates 310 are set at one end in the corresponding clearance groove 37 and the other end is hinged to the hinge plate 36. The spring is fixed to one end of the adjusting rod 311 by the positioning bolt 312. The other end of the adjusting rod 311 is connected to the hinge pressure plate 310. The adjusting inner inclined ring 38 is sleeved on the positioning post 35 and cooperates with the adjusting rod 311.

[0050] Specifically, the clamping cylinder 33 drives the clamping pull column 34 to rise and fall. When the clamping pull column 34 rises, the hinge plate 36 drives the hinge pressure plate 310 and the adjusting rod 311 to rise. The rising adjusting rod 311 will contact the adjusting inner inclined ring 38, causing the adjusting rod 311 to move along the inner wall of the adjusting inner inclined ring 38, thereby bringing the adjusting rod 311 closer to the clamping pull column 34. The rising hinge pressure plate 310 will release the clamped swing arm 2 and move towards the clamping pull column 34 simultaneously with the adjusting rod 311, allowing the swing arm 2 to be removed. When the clamping pull column 34 falls, the spring causes the adjusting rod 311 to move away from the clamping pull column 34 and rest against the inner wall of the adjusting inner inclined ring 38. The hinge pressure plate 310 moves away from the clamping pull column 34 until it presses on the swing arm 2 to fix it.

[0051] In another embodiment of the present invention, a positioning plate 39 is connected to the positioning post 35.

[0052] Specifically, the support surface of the swing arm 2 is increased by setting the positioning plate 39.

[0053] The specific embodiments of the present invention have been described in detail above, but they are merely examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the present invention are covered within the scope of the present invention.
