Description

Technical Field

[0001] This utility model relates to the technical field of caster production equipment, and in particular to an assembly line for caster base plates. Background Technology

[0002] Casters mainly consist of a base plate, steel balls, a chuck, a bracket, and a wheel body. The base plate, chuck, and bracket are riveted together.

[0025] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0026] Reference Figures 1 to 9 An assembly line for caster base plates includes a first support base 1, a first turntable 11 disposed above the first support base 1, and a first drive mechanism 12 disposed on the first support base 1 and driving the first turntable 11 to rotate. The first turntable 11 is provided with a plurality of fixed seats 13. A rivet feeding device 2, a base plate feeding device 3, and a wave plate feeding device 4 are sequentially disposed on the side of the first turntable 11 and along its rotation direction. The first support base 1 includes a first conveying device 5 disposed between the first turntable 11 and the rivet feeding device 2 and capable of conveying rivets from the rivet feeding device 2 to the fixed seats 13; a second conveying device 6 disposed between the first turntable 11 and the base plate feeding device 3 and capable of conveying base plates from the base plate feeding device 3 to the fixed seats 13; and a third conveying device 7 disposed between the first turntable 11 and the wave plate feeding device 4 and capable of conveying wave plates from the wave plate feeding device 4 to the fixed seats 13. In this way, the first drive mechanism 12 drives the first turntable 11 to rotate, which can drive the fixed seat 13 to move sequentially to the corresponding workstations of the rivet feeding device 2, the base plate feeding device 3, and the wave plate feeding device 4. Then, in conjunction with the first conveying device 5, the second conveying device 6, and the third conveying device 7, the rivets, base plates, and wave plates are assembled respectively, thereby realizing fully automated production and improving production efficiency.

[0027] In this design, the fixed base 13 includes a positioning groove 131 on its upper side for placing the base plate, and a positioning hole 132 on the bottom surface of the positioning groove 131 for placing rivets. The contour of the bottom surface of the positioning groove 131 matches the contour of the bottom surface of the base plate, thereby enabling precise positioning of the base plate and preventing it from shifting or shaking after being placed on the fixed base 13. This ensures accurate assembly between the base plate and the subsequent pulsator, improving overall assembly precision. Furthermore, the positioning hole 132 limits the rivet's position, preventing it from shifting during the movement of the fixed base 13 or during subsequent assembly, ensuring precise alignment of the rivet with the corresponding mounting holes on the base plate and pulsator. Four fixed bases 13 are evenly distributed on the first turntable 11, enabling multi-station parallel operation and further improving production efficiency.

[0028] In this scheme, the rivet feeding device 2 includes a first vibrating feeding plate 21 disposed on a first support base 1, and a first feeding channel 22 disposed on the first support base 1 and connected to the outlet end of the first vibrating feeding plate 21 for conveying rivets. The first feeding channel 22 has a slope, and its width corresponds to the width of the rivet, so that after the rivets are discharged from the first vibrating feeding plate 21, they can move one after another along the first feeding channel 22 to their end.

[0029] In this solution, the first conveying device 5 includes a first support frame 51 mounted on the first support base 1, a first finger cylinder 52 mounted above the first feeding channel 22 and capable of clamping and conveying rivets located at the end of the first feeding channel 22 to the fixed base 13, a first push rod 53 mounted on the first support frame 51 and capable of driving the first finger cylinder 52 to move up and down, and a second push rod 54 mounted on the first support frame 51 and capable of driving the first push rod 53 to move left and right. A connecting seat is provided between the first finger cylinder 52 and the first push rod 53 to connect the two, and a movable seat is provided between the first push rod 53 and the second push rod 54 to connect the two and be movable left and right on the first support frame 51. Simultaneously, a laser sensor is provided on the first support frame 51 to detect whether the fixed base 13 has moved to its corresponding workstation.

[0030] In this design, the base plate loading device 3 includes a second support base 31 located beside the first support base 1, a second turntable 32 located above the second support base 31, a second drive mechanism 33 located on the second support base 31 and capable of driving the second turntable 32 to rotate, several shelves 34 located on the second turntable 32 for stacking base plates, and a third push rod 35 located on the second support base 31 for pushing the base plates placed in the shelves 34 to move upward. Thus, by rotating the second turntable 32, base plates stacked on different shelves 34 can be loaded, and the third push rod 35 pushes the base plates in the shelves 34 to facilitate their removal.

[0031] In this design, the shelf 34 includes a base 341 mounted on the second turntable 32 and U-shaped positioning frames 342 mounted on opposite sides of the base 341. A storage groove 343 for storing the bottom plate is formed between the two U-shaped positioning frames 342, thus enabling the stacking of the bottom plate. The base 341 has a first through hole 3411, and the second turntable 32 has a second through hole 321 communicating with the first through hole 3411. The bottom of the storage groove 343 has a push plate 36 that can move up and down to push the bottom plate placed on it upwards. The bottom surface of the push plate 36 has a connector 361 that can cooperate with the protruding end of the third push rod 35, thereby preventing the protruding end of the third push rod 35 from directly contacting the bottom plate, thus avoiding scratches or indentations. At the same time, it can stably lift the top bottom plate to the specified material picking height. Meanwhile, there is a gap between the two U-shaped positioning frames 342, and a laser sensor is installed above the gap to detect whether the bottom plate in the storage slot 343 has been completely removed.

[0032] In this design, the second conveying device 6 includes a second support frame 61 mounted on the first support base 1, a first suction cylinder 62 mounted above the shelf 34 and capable of lifting and conveying the top plate of the shelf 34 to the fixed base 13, a fourth push rod 63 mounted on the second support frame 61 and capable of driving the first suction cylinder 62 to move up and down, and a fifth push rod 64 mounted on the second support frame 61 and capable of driving the fourth push rod 63 to move back and forth. A connecting seat is provided between the first suction cylinder 62 and the fourth push rod 63 to connect them, and a movable seat is provided between the fourth push rod 63 and the fifth push rod 64 to connect them and move back and forth on the second support frame 61. Simultaneously, a laser sensor is provided on the second support frame 61 to detect whether the fixed base 13 has moved to its corresponding workstation.

[0033] In this design, the fixed base 13 has a third through hole 133 communicating with the positioning hole 132, and the first turntable 11 has a fourth through hole 111 communicating with the third through hole 133. A second suction cylinder 8 and a telescopic cylinder 9 for driving the second suction cylinder 8 to move up and down are provided on the first support base 1 and below the fourth through hole 111. This allows the telescopic cylinder 9 to attract the rivets located in the positioning hole 132, preventing the bottom from touching the rivets and causing it to wobble and fall over when the base plate is lowered above the positioning groove 131, thus avoiding the need for manual repositioning.

[0034] In this design, the wave plate feeding device 4 includes a third support base 41 located beside the first support base 1, a second vibrating feeding plate 42 located on the third support base 41, and a second feeding channel 43 located on the first support base 1 and connected to the outlet end of the second vibrating feeding plate 42 for conveying the wave plate. The second feeding channel 43 is equipped with a conveyor belt for conveying the wave plate, and a limiting plate at its end restricts the position of the wave plate, thereby facilitating its removal.

[0035] In this design, the third conveying device 7 includes a third support frame 71 mounted on the first support base 1, a third suction cylinder 72 mounted above the second feeding channel 43 and capable of picking up and conveying the pulsator located at the end of the second feeding channel 43 to the fixed base 13, a sixth push rod 73 mounted on the third support frame 71 and capable of driving the third suction cylinder 72 to move up and down, and a seventh push rod 74 mounted on the third support frame 71 and capable of driving the sixth push rod 73 to move left and right. A connecting seat is provided between the third suction cylinder 72 and the sixth push rod 73 to connect them, and a movable seat is provided between the sixth push rod 73 and the seventh push rod 74 to connect them and move left and right on the third support frame 71. Simultaneously, a laser sensor is provided on the limiting part at the end of the second feeding channel 43 to detect whether the fixed base 13 has moved to its corresponding workstation.

[0036] In this design, the first drive mechanism 12 includes a first drive motor 121 disposed below the first support base 1, and a first gearbox 122 disposed on the first support base 1 and drivenly connected to the first drive motor 121. The first turntable 11 is disposed on the upper output end of the first gearbox 122. This allows the fixed base 13 to be moved to different workstations by rotating the first turntable 11, thereby assembling the rivet, base plate, and gearbox together, and then sending them to the next production line for further production.

[0037] In this design, the second drive mechanism 33 includes a second drive motor 331 disposed below the second support base 31, and a second gearbox 332 disposed on the second support base 31 and driven by the second drive motor 331. The second turntable 32 is disposed on the upper output end of the second gearbox 332. This mechanism is used for loading base plates. When the laser sensor detects that a base plate on the shelf 34 has been completely picked up, it drives the second turntable 32 to rotate, allowing the first suction cup to pick up the next base plate from the shelf 34 for loading.
