Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber assembly, and more specifically to an automatic assembly device for rubber spring composite shock absorbers. Background Art

[0002] With the continuous improvement of the shock absorption performance requirements in fields such as automobiles, rail transit, and industrial machinery, rubber spring composite shock absorbers have been widely used due to their excellent buffering performance and durability. Traditional shock absorber assembly mainly relies on manual operation, and there are the following technical defects: 1. Low assembly accuracy: It is difficult for manual assembly to ensure the coaxiality and pre-tightening force consistency between the rubber spring and metal components, affecting the product yield rate; 2. Efficiency bottleneck: Processes such as manual tightening and detection take a long time and are difficult to meet the requirements of mass production; 3. Poor stability: Manual operation is prone to cause component misalignment or uneven fastening force, leading to early failure of the shock absorber. Coupled with the lack of adaptive adjustment ability of the existing equipment clamping mechanism, it cannot be compatible with shock absorbers of different specifications. Based on this, the present invention proposes an automatic assembly device for rubber spring composite shock absorbers to solve the above problems. Summary of the Invention

The front end of the base is provided with a hollow structure, and a limiting rod is movably connected to the hollow part. A transmission device is correspondingly arranged at the front end of the limiting rod. At both ends of the top of the base, there are raised structures, and lifting columns are fixedly connected to both raised parts. The lifting columns are used to drive the top device to adjust up and down to meet the assembly requirements of shock absorbers of different specifications. At the top of the two lifting columns, a top plate is fixedly connected. At both ends of the bottom of the top plate, rotating devices are fixedly installed. The two rotating devices are used to alternately clamp and twist-fix the top of the shock absorber. A detection device is arranged between the two rotating devices. The detection device is used to detect the assembly state of the shock absorber and determine whether there is any loosening phenomenon; The bottom of the detection device is correspondingly connected to a fixing device. The fixing device is used to fix the outer surface of the shock absorber when the rotating device is working to ensure the stability of the assembly process. The transmission device includes a sliding device and a clamping device. The sliding device is used to drive the clamping device to move horizontally, so that the clamping device can penetrate the bottom of the shock absorber to the outer surface of the limiting rod for subsequent assembly.

[0005] As a preferred technical solution of the present invention, the sliding device includes two concave blocks. The bottoms of the two concave blocks are fixedly connected to the hollow part of the bottom of the base. Slide rods are fixedly connected to the grooves at the tops of the two concave blocks, and sliding blocks are movably connected to the outer surfaces of the two slide rods.

[0006] As a preferred technical solution of the present invention, L-shaped blocks are fixedly connected to the tops of the two sliding blocks. The centers of the two L-shaped blocks are movably connected to a first threaded rod, and both ends of the two first threaded rods are movably connected to the inner sides of the tops of the two concave blocks. A support bottom plate is fixedly connected to the tops of the two L-shaped blocks, and a clamping device is fixedly connected to the top of the support bottom plate.

[0007] As a preferred technical solution of the present invention, the clamping device includes a rectangular block. The bottom of the rectangular block is fixedly connected to the top of the support bottom plate. Connecting blocks are fixedly connected to both sides of the rectangular block. First elliptical rods are movably connected to the grooves at the tops of the two connecting blocks, and second elliptical rods are movably connected to the grooves at the tops of the two first elliptical rods.

[0008] As a preferred technical solution of the present invention, clamping blocks are movably connected to both sides of the bottoms of the two second elliptical rods. The center of the clamping block is movably connected to a second threaded rod, and the bottom of the second threaded rod is movably connected to the center of the top of the rectangular block. Third elliptical rods are movably connected to the grooves at both sides of the tops of the clamping blocks. Curved rods are movably connected to the tops of the two third elliptical rods. Fixed plates are movably connected to the tops of the two curved rods. Retractable clamps are fixedly connected to the inner sides of the two fixed plates.

[0009] As a preferred technical solution of the present invention, the fixing device includes a cylinder. A T-shaped plate is fixedly connected to the bottom of the cylinder. A double-row rack is fixedly connected to the output shaft end of the cylinder. Gears are meshed and connected to the outer surfaces of both sides of the double-row rack.

[0010] As a preferred technical solution of the present invention, the centers of the two gears are movably connected to a rotating shaft, and the bottoms of the two rotating shafts are movably connected to the top of the T-shaped plate. Long racks are meshed and connected to the outer surfaces of the bottoms of the two gears. A support column passes through the centers of the two long racks, and both ends of the support column are movably connected to the protruding parts at the bottom of the T-shaped plate. Fixed blocks are fixedly connected to one ends of the outer sides of the two long racks.

[0011] Compared with the prior art, the beneficial effects of the present invention are: (1)The automatic assembly equipment for rubber spring composite shock absorbers realizes the stable sliding of the sliding block along the axis direction of the sliding rod by setting sliding blocks on the outer surfaces of two sliding rods and using the sliding pair. A threaded through-hole adapted to the first threaded rod is provided in the middle of the L-shaped block. When the external driving device drives the first threaded rod to rotate, based on the principle of screw drive, since the L-shaped block is fixedly connected to the bottom of the sliding block and the sliding rod restricts its circumferential rotation, the sliding block is driven to perform a linear motion along the sliding rod. Finally, driven by the synchronous rotation of the two first threaded rods, the support base plate fixedly connected to the tops of the two L-shaped blocks drives the clamping device installed thereon to move synchronously towards the top of the limiting rod.

[0012] (2)The automatic assembly equipment for rubber spring composite shock absorbers fixes a rectangular block on the top of the support base plate, enabling the rectangular block to move synchronously with the support base plate in the horizontal direction. A threaded hole adapted to the second threaded rod is provided on the top of the rectangular block. When the second threaded rod rotates under the drive of the external driving device, based on the principle of screw drive, the clamping block threadedly connected to the outer surface of the second threaded rod will quickly move downward along the axis of the second threaded rod, so that other devices in the groove parts at both ends of the clamping block will continuously move downward under the drive of the clamping block, and finally perform the pulling action.

[0013] (3)The automatic assembly equipment for rubber spring composite shock absorbers movably connects the tops of the second elliptical rod and the third elliptical rod to the groove at the bottom of the bent rod. When the clamping block moves under the pulling action, since the clamping block is movably connected to the tops of the second elliptical rod and the third elliptical rod, one end position of the second elliptical rod and the third elliptical rod will rise. Also, because both sides of the second elliptical rod are movably connected to the top of the first elliptical rod, under the restriction of this structure, the action driven by the clamping block mainly causes the other end of the third elliptical rod to rise. With the movement of the third elliptical rod, the bent rod movably connected to the tops of the third elliptical rod and the second elliptical rod will generate corresponding movements, and this movement further drives the two contraction clips fixedly connected to the inner side of the fixed plate to move towards the middle.

[0014] (4)The automatic assembly equipment for rubber spring composite shock absorbers installs a double-row rack at the output shaft end of the cylinder. When the cylinder operates, it can drive the double-row rack to perform reciprocating telescopic movements. When the double-row rack moves, the gears meshing with both sides of it start to rotate under the support of the rotating shaft. Since the gears mesh with the two long racks on the bottom outer surface, the rotation of the gears will drive these two long racks to move towards the middle. The use of gears for transmission can effectively reduce the situation of jamming due to long-term use. The two long racks are supported and guided on the outer surface of the support column. As the long racks move, they will drive the two fixed blocks connected to them to gradually approach, and finally realize the fixation of the outer surface of the shock absorber.

The front end of the base 1 is provided with a hollow structure, and a limiting rod 2 is movably connected to the hollow part. A transmission device 3 is correspondingly arranged at the front end of the limiting rod 2. Both ends of the top of the base 1 are provided with convex structures, and lifting columns 4 are fixedly connected to both convex parts. The lifting columns 4 are used to drive the top device to adjust up and down to meet the assembly requirements of shock absorbers of different specifications. The tops of the two lifting columns 4 are provided with a top plate 5, and the tops of the two lifting columns 4 are fixedly connected to the bottom of the top plate 5. Rotating devices 6 are fixedly installed at both ends of the bottom of the top plate 5. The two rotating devices 6 are used to alternately clamp and twist-fix the top of the shock absorber. A detection device 7 is arranged between the two rotating devices 6. The detection device 7 is used to detect the assembly state of the shock absorber and judge whether there is any loosening phenomenon; A fixing device 8 is arranged at the bottom of the detection device 7, and the bottom of the detection device 7 is correspondingly connected to the top of the fixing device 8. The fixing device 8 is used to fix the outer surface of the shock absorber when the rotating device 6 works to ensure the stability of the assembly process. The transmission device 3 includes a sliding device 31 and a clamping device 32. The sliding device 31 is used to drive the clamping device 32 to move horizontally, so that the clamping device 32 can penetrate the bottom of the shock absorber to the outer surface of the limiting rod 2 for subsequent assembly.

[0019] Embodiment 2: On the basis of Embodiment 1, as Figures 3 - 8 shown, the sliding device 31 includes two concave blocks 311. The bottoms of the two concave blocks 311 are fixedly connected to the hollow part at the bottom of the base 1. Sliding rods 312 are arranged at the top grooves of the two concave blocks 311, and the bottoms of the two sliding rods 312 are fixedly connected to the top grooves of the two concave blocks 311. Sliding blocks 313 are arranged on the outer surfaces of the two sliding rods 312, and the outer surfaces of the two sliding rods 312 are movably connected to the grooves of the sliding blocks 313.

[0020] L-shaped blocks 314 are provided at the tops of both of the two sliding blocks 313, and the bottoms of the L-shaped blocks 314 are fixedly connected to the tops of the two sliding blocks 313. First threaded rods 315 are provided at the centers of both of the two L-shaped blocks 314, and the centers of the two L-shaped blocks 314 are movably connected to the outer surfaces of the first threaded rods 315. Both ends of the two first threaded rods 315 are movably connected to the inner sides of the tops of the two concave blocks 311. A support bottom plate 316 is provided at the tops of the two L-shaped blocks 314, and the bottoms of the two L-shaped blocks 314 are fixedly connected to the top of the support bottom plate 316. A clamping device 32 is provided on the top of the support bottom plate 316. By providing sliding blocks 313 on the outer surfaces of the two sliding rods 312, smooth sliding of the sliding blocks 313 along the axial direction of the sliding rods 312 is achieved by using a sliding pair. Threaded through holes adapted to the first threaded rods 315 are provided in the middle of the L-shaped blocks 314. When an external driving device drives the first threaded rods 315 to rotate, based on the principle of screw drive, since the L-shaped blocks 314 are fixedly connected to the bottoms of the sliding blocks 313 and the sliding rods 312 restrict their circumferential rotation, the sliding blocks 313 are driven to perform linear motion along the sliding rods 312. Finally, driven by the synchronous rotation of the two first threaded rods 315, the support bottom plate 316 fixedly connected to the tops of the two L-shaped blocks 314 drives the clamping device 32 mounted thereon to move synchronously towards the top of the limiting rod 2. This automated transmission structure replaces traditional manual operations, not only greatly shortening the assembly time, but also achieving precise positioning and efficient movement of the clamping device, effectively improving the assembly efficiency and stability. Moreover, the top of the support bottom plate 316 is fixedly connected to the bottom of the clamping device 32.

[0021] The clamping device 32 includes a rectangular block 321. The bottom of the rectangular block 321 is fixedly connected to the top of the support bottom plate 316. Connection blocks 322 are provided on both sides of the rectangular block 321, and the bottoms of the connection blocks 322 are fixedly connected to both sides of the rectangular block 321. First elliptical rods 323 are provided at the grooves on the tops of the two connection blocks 322, and the bottoms of the first elliptical rods 323 are movably connected to the grooves on the tops of the two connection blocks 322. By fixedly arranging the rectangular block 321 on the top of the support bottom plate 316, the rectangular block 321 can move synchronously along the horizontal direction with the support bottom plate 316. Threaded holes adapted to the second threaded rods 326 are provided on the top of the rectangular block 321. When the second threaded rods 326 rotate under the drive of an external driving device, based on the principle of screw drive, the clamping blocks 325 threadedly connected to the outer surfaces of the second threaded rods 326 will quickly move downward along the axial direction of the second threaded rods 326, so that other devices in the groove parts at both ends of the clamping blocks 325 will continuously move downward under the drive of the clamping blocks 325, and finally a pulling action is performed. Second elliptical rods 324 are provided at the grooves on the tops of the two first elliptical rods 323, and the two sides of the second elliptical rods 324 are movably connected to the grooves on the tops of the two first elliptical rods 323.

[0022] On both sides of the bottom of the two second elliptical rods 324, clamping blocks 325 are provided, and both sides of the bottom of the two second elliptical rods 324 are movably connected to the grooves at both ends of the clamping blocks 325. A second threaded rod 326 is provided at the center of the clamping block 325, and the center of the clamping block 325 is movably connected to the outer surface of the second threaded rod 326. The bottom of the second threaded rod 326 is movably connected to the top center of the rectangular block 321. Third elliptical rods 327 are provided at the grooves on both sides of the top of the clamping block 325, and the bottoms of the third elliptical rods 327 are movably connected to the grooves on both sides of the top of the clamping block 325. Bending rods 328 are provided at the tops of the two third elliptical rods 327, and the bottoms of the two third elliptical rods 327 are movably connected to the hollow parts on the inner sides of the bottoms of the bending rods 328. Fixing plates 329 are provided at the tops of the two bending rods 328, and the tops of the two bending rods 328 are movably connected to the outer sides of the fixing plates 329. The tops of the two second elliptical rods 324 are movably connected to the grooves at the bottoms of the fixing plates 329. Shrink clamps 3210 are provided on the inner sides of the two fixing plates 329. By movably connecting the tops of the second elliptical rods 324 and the third elliptical rods 327 to the grooves at the bottoms of the bending rods 328, when the clamping block 325 moves under the pulling action, since the clamping block 325 is movably connected to the tops of the second elliptical rod 324 and the third elliptical rod 327, one end position of the second elliptical rod 32 and the third elliptical rod 327 will rise. Also, because the two sides of the second elliptical rod 324 are movably connected to the top of the first elliptical rod 32, under this structural limitation, the movement driven by the clamping block 325 mainly causes the other end of the third elliptical rod 327 to rise. Along with the movement of the third elliptical rod 327, the bending rod 328 movably connected to its top and the top of the second elliptical rod 324 will generate corresponding movements. This movement further drives the two shrink clamps 3210 fixedly connected to the inner sides of the fixing plate 329 to move towards the middle, ultimately realizing the fixation of the outer surface of the shock absorber, and the inner sides of the two fixing plates 329 are fixedly connected to the bottoms of the shrink clamps 3210.

[0023] The fixing device 8 includes a cylinder 81. A T-shaped plate 82 is arranged at the bottom of the cylinder 81, and the bottom of the cylinder 81 is fixedly connected to one end of the top of the T-shaped plate 82. A double-row rack 83 is arranged at the output shaft end of the cylinder 81, and the output shaft end of the cylinder 81 is fixedly connected to the bottom of the double-row rack 83. Gear 84 is arranged on the outer surfaces of both sides of the double-row rack 83, and the outer surfaces of both sides of the double-row rack 83 are meshed with the outer surface of the gear 84. By installing the double-row rack 83 at the output shaft end of the cylinder 81, when the cylinder 81 acts, it can drive the double-row rack 83 to make a reciprocating telescopic movement. When the double-row rack 83 moves, the gears 84 meshed with its two sides start to rotate under the support of the rotating shaft 85. Since the gears 84 are meshed with the two long racks 86 on the outer surface of the bottom, the rotation of the gears 84 will drive these two long racks 86 to move towards the middle. And the use of the gears 84 for transmission can effectively reduce the situation of jamming due to long-term use.

[0024] Rotating shafts 85 are arranged at the centers of the two gears 84, and the centers of the two gears 84 are movably connected to the outer surfaces of the tops of the rotating shafts 85. The bottoms of the two rotating shafts 85 are movably connected to the top of the T-shaped plate 82. Long racks 86 are arranged on the outer surfaces of the bottoms of the two gears 84, and the outer surfaces of the bottoms of the two gears 84 are meshed with the outer surfaces of the long racks 86. A support column 87 is arranged at the center of the two long racks 86, and the center of the two long racks 86 is penetrated through the outer surface of the support column 87. The two ends of the support column 87 are movably connected to the protruding parts at the bottom of the T-shaped plate 82. The two long racks 86 are supported and guided on the outer surface of the support column 87. As the long racks 86 move, they will drive the two fixed blocks 88 connected to them to gradually approach, and finally realize the fixing of the outer surface of the shock absorber, reducing the risk during use. Fixed blocks 88 are arranged at one ends of the outer sides of the two long racks 86, and one ends of the outer sides of the two long racks 86 are fixedly connected to the bottoms of the fixed blocks 88.

[0025] The working principle of the present invention is as follows: This automated assembly equipment is mainly used for the assembly of rubber spring composite shock absorbers. Through the coordinated work of multiple devices, functions such as automatic positioning, clamping, assembly, and status detection of the shock absorbers are realized. The core lies in the mechanical transmission and coordinated actions between the devices to adapt to the assembly requirements of shock absorbers of different specifications and improve the assembly efficiency and stability; Working principle of the sliding device 31: An external driving device (such as a motor) drives the first threaded rod 315 to rotate. Since the threaded through-hole in the middle of the L-shaped block 314 is adapted to the first threaded rod 315, and the bottom of the L-shaped block 314 is fixedly connected to the sliding block 313, while the sliding block 313 is sleeved on the sliding rod 312, and the sliding rod 312 restricts the circumferential rotation of the sliding block 313. According to the principle of screw drive, the rotation of the first threaded rod 315 will drive the L-shaped block 314 and the sliding block 313 to move linearly along the sliding rod 312. When the two first threaded rods 315 rotate synchronously, they will drive the support bottom plate 316 fixedly connected to the tops of the two L-shaped blocks 314, driving the clamping device 32 installed thereon to move synchronously towards the top of the limiting rod 2, realizing the positioning movement of the bottom of the shock absorber in the horizontal direction; Working principle of the clamping device 32: When the second threaded rod 326 rotates driven by an external driving device (such as a motor), based on the principle of screw drive, the clamping block 325 threadedly connected to the outer surface of the second threaded rod 326 will quickly move downward along the axial direction of the second threaded rod 326. The two groove parts at both ends of the clamping block 325 are movably connected to the bottoms of the second elliptical rod 324 and the third elliptical rod 327. When the clamping block 325 moves downward, it will cause one end of the second elliptical rod 324 and the third elliptical rod 327 to rise in position. Since both sides of the second elliptical rod 324 are movably connected to the top of the first elliptical rod 323, under this structural limitation, the movement driven by the clamping block 325 mainly causes the other end of the third elliptical rod 327 to rise. Along with the movement of the third elliptical rod 327, the bending rod 328 movably connected to the tops of the third elliptical rod 327 and the second elliptical rod 324 will generate corresponding movements, further driving the two shrinkage clamps 3210 fixedly connected to the inner side of the fixed plate 329 to move towards the middle, ultimately realizing the clamping and fixing of the outer surface of the shock absorber; Working principle of the fixing device 8: When the air cylinder 81 is driven, its output shaft end drives the double-row rack 83 fixedly connected thereto to perform reciprocating telescopic movements. The outer surfaces on both sides of the double-row rack 83 are meshed with the outer surface of the gear 84. When the double-row rack 83 moves, it will drive the gear 84 to rotate supported by the rotating shaft 85. Since the gear 84 is meshed with the two long racks 86 on the bottom outer surface, the rotation of the gear 84 will drive these two long racks 86 to move towards the middle under the guidance of the support column 87, making the fixed blocks 88 at the outer ends of the long racks 86 approach accordingly, thereby realizing the fixing of the outer surface of the shock absorber. By adopting the gear drive method, it can effectively reduce the situation of jamming due to long-term use and ensure the stable operation of the device; Rotating device 6: Two rotating devices 6 are installed at both ends of the bottom of the top plate 5, and can alternately perform clamping and torsional fixing operations on the top of the shock absorber. During the assembly process of the shock absorber, the coordinated work of the rotating device 6 helps to complete the assembly process of the top of the shock absorber, ensuring the accuracy and stability of the assembly; Detection device 7: Located between two rotating devices 6, it is used to detect the assembly state of the shock absorber. After the shock absorber is assembled, the detection device 7 will detect it to determine whether there are assembly problems such as looseness, ensuring product quality.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
