Description

Technical Field

[0001] This invention relates to the technical field of automotive component assembly, and more particularly to a press-fitting mechanism for automotive rubber parts. Background Technology

[0002] Car shock absorber brackets are key components installed on the car chassis to connect the shock absorbers to the car body. Their function is to effectively control vehicle bumps and improve driving stability, handling, and ride comfort. Current shock absorber brackets are equipped with multiple rubber seats to absorb and dampen impacts and vibrations from the road surface, reducing vibrations and noise transmitted to the car body.

[0003] Because the individual rubber seats in the shock absorber bracket are not uniformly vertically distributed, but rather inclined as needed, the pressing of these rubber seats is difficult to complete with automated equipment and must be done manually, resulting in a slow pressing speed. Furthermore, since there are at least three rubber seats, and the shock absorber bracket must be fixed to the matching fixture before pressing, each rubber seat must be pre-placed into its corresponding mounting slot on the shock absorber bracket, and the shock absorber bracket must be removed from the fixture after pressing, the entire operation is cumbersome, ultimately leading to low work efficiency. In addition, the entire pressing process requires multiple people to complete simultaneously, resulting in high labor costs and consequently high processing costs, all of which urgently need to be addressed. Summary of the Invention

[0043] The upper edges of the left and right sides of the opening of the U-shaped card plate 41 are both formed with a relief slope 411.

[0044] Working principle:

[0045] The shock absorber bracket is placed horizontally at the top right end of the two conveyor belts 7 and located to the right of the pre-assembled components. After the two conveyor belts 7 are started, the shock absorber bracket will move to the left under the drive of the two conveyor belts 7. This drives the telescopic end of the stop cylinder 63 in the stop mechanism 6 located at the lifting mechanism 5 to extend outward, thereby driving the stop bar 62 and the two stop posts 64 to move upward until the upper end of each stop post 64 is higher than the top of the shock absorber bracket. When the shock absorber bracket moves to the bottom of the loading mechanism 2, the left side of the shock absorber bracket will be blocked by the upper ends of the two stop posts 64 and will not be able to move to the left.

[0046] Next, the telescopic end of the second traction cylinder 23 is driven to retract inward to move the lifting block 24 upward, thereby driving the bracket 252 to move inward by means of each transmission rod 255 in each loading unit 25 until the lower end of the screw 254 is directly above the bottom of the locking groove 541; then the telescopic end of the lifting cylinder 52 in the lifting mechanism 5 is driven to extend outward to move the pallet 51 vertically upward by means of the guide post 53, thereby lifting the shock absorber bracket upward to separate it from the two conveyor belts 7, while each positioning pin 56 located on the top of the pallet 51 is inserted into the positioning hole located at the bottom of the shock absorber bracket to prevent the shock absorber bracket from shifting.

[0047] Before this, the four rubber seats must be vertically inserted from the outside to the inside into the outer openings of the four rectangular guide tubes 54 in the lifting mechanism 5, while the top boss of each rubber seat passes through the locking groove 541 until the top boss reaches the bottom of the locking groove 541, because the outer diameter of the top boss is larger than the width of the guide groove 542; at this time, the four rectangular guide tubes 54 are all located inside the shock absorber bracket, and the openings of the locking grooves 541 on the four rectangular guide tubes 54 are respectively aligned with the openings of the four mounting slots located inside the shock absorber bracket.

[0048] During the ascent of the pallet 51, the servo motor 253 in each loading unit 25 is simultaneously activated to rotate its shaft, thereby driving the screw 254 to rotate. Since the four rectangular guide tubes 54 rise synchronously with the pallet 51, the four rubber seats also rise synchronously, so that the lower ends of the screws 254 in the four loading units 25 are gradually inserted into the threaded holes screwed onto the four rubber seats. Subsequently, the telescopic end of the second traction cylinder 23 is extended outward to similarly drive the four screws 254 to move outward, thereby driving the four rubber seats to move in tandem. The screw moves step by step, causing each rubber seat to leave the locking groove 541 on its rectangular guide tube 54 and be embedded into the opening of the four mounting slots inside the shock absorber bracket. Then, the rotating shaft of the servo motor 253 in each loading unit 25 is reversed, and the telescopic end of the lifting cylinder 52 is driven to retract inward so that the four rubber seats are moved down by means of the support plate 51. This causes the lower end of each screw 254 to leave the corresponding rubber seat, thereby pre-installing the four rubber seats into the opening of the four mounting slots inside the shock absorber bracket.

[0049] After the shock absorber bracket is lowered onto the two conveyor belts 7 again, the telescopic end of the stop cylinder 63 in the stop mechanism 6 located at the lifting mechanism 5 is driven to retract inward, thereby causing the stop bar 62 and the two stop posts 64 to move downward until the upper end of each stop post 64 is lower than the bottom of the shock absorber bracket, thus causing the shock absorber bracket to continue to move to the left until the shock absorber bracket is above the U-shaped positioning plate 41; thereafter, the telescopic end of the stop cylinder 63 in the stop mechanism 6 located at the U-shaped positioning plate 41 is driven to extend outward to prevent the shock absorber bracket from moving further to the left.

[0050] Next, the telescopic end of the shifting cylinder 33 in the drive positioning mechanism 3 extends outward to drive the clamping cylinder 35 and the two clamping bars 34 forward with the help of the moving plate 32, until the front ends of the two clamping bars 34 are respectively located on the top left and right sides of the shock absorber bracket. Then, the telescopic end of the drive clamping cylinder 35 retracts inward to drive the two clamping bars 34 to move closer to each other, thereby driving the two clamping blocks 310 to move simultaneously, until the limiting notches 3101 on the two clamping blocks 310 press against the left and right corners of the shock absorber bracket respectively. At this time, the inner walls of the front ends of the two clamping bars 34 also adhere to the outer walls of the left and right sides of the shock absorber bracket respectively, thus completing the positioning of the shock absorber bracket. At this time, each protrusion on the outer walls of the left and right sides of the shock absorber bracket is embedded into a corresponding positioning groove 341.

[0051] During the above process, the telescopic end of the positioning cylinder 43 in the positioning mechanism 4 is also driven to retract inward to move the U-shaped positioning plate 41 forward and downward, while simultaneously causing the end of the swing arm 42 to swing downward until the opening of the U-shaped positioning plate 41 is in front of the two rear rubber seats. During the downward swing of the end of the swing arm 42, the telescopic end of the first traction cylinder 451 in the pulling unit 45 is also driven to extend outward to drive the ends of the two clamping arms 454 in each gripper to move away from each other with the help of the moving beam 453, until the ends of the two clamping arms 454 in the left gripper are respectively located on the top left and right sides of the left rear rubber seat, while the ends of the two clamping arms 454 in the right gripper are respectively located on the top left and right sides of the right rear rubber seat.

[0052] It is worth mentioning that: because the openings of the two mounting slots behind the shock absorber bracket are horizontal, but their bottoms are inclined with the front lower than the back, the two rubber seats at the rear, which are pre-installed vertically, need to be pressed into place. Therefore, during pressing, the telescopic end of the first traction cylinder 451 in the pulling unit 45 needs to be driven to retract inward to similarly drive the ends of the two clamping arms 454 in each gripper to move closer to each other until the locking blocks 4541 on the ends of the two clamping arms 454 in each gripper clamp the corresponding... The top left and right sides of a rubber seat; then the telescopic end of the drive positioning cylinder 43 extends outward to drive the U-shaped positioning plate 41 to move backward and upward in the same way, while forcing the end of the swing arm 42 to swing upward to drive the pulling unit 45 to swing synchronously in the same way; when the U-shaped positioning plate 41 moves backward and upward, the left and right sides of the opening of the U-shaped positioning plate 41 will push the bottom of the two rubber seats to turn backward and upward and move. At the same time, the two rubber seats will tilt forward and turn under the action of the pulling unit 45 to assist in pressing.

[0053] After pressing is completed, the telescopic end of the first traction cylinder 451 in the drive pulling unit 45 extends outward to release the tops of the two rubber seats in the same way. At the same time, the telescopic end of the locking cylinder 43 in the locking mechanism 4 retracts inward, thereby driving the U-shaped locking plate 41 to move forward and downward so that the left and right sides of its opening are away from the bottom of the two rubber seats. Then, the telescopic end of the clamping cylinder 35 is driven outward to move the two clamping bars 34 away from each other, thereby releasing the shock absorber bracket. Then, the telescopic end of the shifting cylinder 33 is driven inward to move the two clamping bars 34 backward in the same way. Finally, the telescopic end of the stop cylinder 63 in the stop mechanism 6 located at the U-shaped locking plate 41 is driven inward to move the shock absorber bracket to the left in the same way.

[0054] This invention can automatically place four rubber seats simultaneously into the openings of four mounting slots inside the shock absorber bracket before pressing, and then automatically press the two rear rubber seats into the designated positions. In addition, the feeding, movement, positioning and unloading of the shock absorber bracket can also be completed automatically, without manual operation throughout the process, which greatly speeds up the pressing speed and simplifies the operation steps, thereby effectively improving work efficiency. Furthermore, the entire pressing process only requires one operator to pre-place the rubber seats, thereby reducing the number of operators and labor intensity, and thus effectively reducing labor costs and processing costs.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
