Description

Technical fields:

[0001] This utility model relates to the field of automated production technology, and specifically to a damper front plug assembly machine. Background technology:

[0002] A damper is a device that uses fluid flow to create a damping effect. It consists of an outer tube unit and a piston unit. The outer tube unit has an axially extending mounting space, while the piston unit includes an axially sliding piston rod and a piston fixed to the piston rod. The piston divides the mounting space into two compartments and, through specific structural designs (such as guide grooves on the piston and grooves in the drain ring), allows the fluid to flow more smoothly as the piston moves, thus producing a damping effect. For example, in drawer slides, the application of dampers can significantly improve the user experience. When the drawer closes, the damper ensures that the drawer closes smoothly and slowly, avoiding noise and impact. This not only protects the drawer and the furniture itself but also extends their lifespan.

[0003] Chinese Patent Publication No. CN201025290Y discloses a damper comprising: an outer tube unit having an axially extending installation space, and a piston unit. The piston unit includes a piston rod, a piston synchronously and fixedly connected to the piston rod, and a drain ring and a retaining ring disposed on the piston. The piston divides the installation space into two spatial portions, including a radially expanding section, a connecting section, and a constricting section with decreasing diameters. A guide groove is recessed in the radially expanding section and the connecting section. The drain ring is arranged around the constricting section and has a first annular surface facing the radially expanding section, and several grooves recessed on the first annular surface. The structure of the piston unit is an innovative design different from previous designs, and the guide groove of the piston and the grooves of the drain ring allow for smoother liquid flow. However, with the continuous improvement of living standards, the demand for dampers in various fields is increasing. Due to the smaller size of the components in miniature dampers, traditional manual assembly is insufficient to meet the large market demand.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figures 1 to 11 The diagram shows a damper fore-end assembly machine, comprising: a first assembly platform 1, a second assembly platform 2, a third assembly platform 3, a first feeding mechanism 4, a second feeding mechanism 5, a third feeding mechanism 6, and a conveying mechanism 7. The first assembly platform 1, the second assembly platform 2, and the third assembly platform 3 are arranged below the conveying mechanism 7. The first feeding mechanism 4, the second feeding mechanism 5, and the third feeding mechanism 6 respectively convey a first workpiece 10, a second workpiece 20, and a third workpiece 30 to the first assembly platform 1, the second assembly platform 2, and the third assembly platform 3, respectively. The conveying mechanism 7 then transfers and assembles the first workpiece 10, the second workpiece 20, and the third workpiece 30 together, replacing manual operation and achieving automated production with higher assembly efficiency.

[0029] A pre-tightening fixture 8 is provided between the second assembly table 2 and the third assembly table 3 to clamp the first workpiece 10 and the second workpiece 20 for simultaneous gripping and transfer by the transport mechanism 7. The pre-tightening fixture 8 includes a third support plate 81, a third guide base 82 mounted on the third support plate 81, a second positioning groove plate 83 mounted on the third guide base 82 for positioning the first workpiece 10, and a third cylinder 84 located below the third guide base 82 for completely inserting the second workpiece 20 into the first workpiece 10. The second positioning groove plate 83 has a second positioning hole 831 for positioning the first workpiece 10. By adding the pre-tightening fixture 8 between the second assembly table 2 and the third assembly table 3, the first workpiece 10 and the second workpiece 20 are initially assembled. Then, the workpiece is transferred to the pre-tightening fixture 8 by the transport mechanism 7 for further tightening, ensuring that the second workpiece 20 is completely inserted into the first workpiece 10.

[0030] The first assembly platform 1, the second assembly platform 2, the pre-tightening tooling platform 8 and the third assembly platform 3 are all arranged at equal intervals below the conveying mechanism 7, and the conveying mechanism 7 is provided with four picking claws 75 for gripping workpieces at equal intervals, and the four picking claws 75 can be located above the first assembly platform 1, the second assembly platform 2, the pre-tightening tooling platform 8 and the third assembly platform 3 at the same time.

[0031] The conveying mechanism 7 includes a first support frame 71, an X-axis drive module 72 mounted on the first support frame 71 and parallel to the assembly table's arrangement direction, a Z-axis drive module 73 mounted on the X-axis drive module 72, and a first support plate 74 mounted on the Z-axis drive module 73 for supporting the four picking claws 75. The four picking claws 75 are horizontally arranged on the first support plate 74. By using four equally spaced picking claws 75 on the conveying mechanism 7, the mechanism can simulate a shift fork to synchronously transfer workpieces, significantly improving efficiency.

[0032] The first feeding mechanism 4, the second feeding mechanism 5 and the third feeding mechanism 6 each include a vibratory plate A, a linear vibrator B and a guide trough C.

[0033] The first assembly platform 1 includes a first support plate 11, a first material distribution base 12 disposed on the first support plate 11 and used to dock with the first feeding mechanism 4, a first material distribution plate 13 slidably disposed in the first material distribution base 12 and perpendicular to the end of the first feeding mechanism 4 to receive the first workpiece 10, a first material sensor 14 disposed on the first material distribution base 12 and used to detect the first workpiece 10, and a first cylinder 15 used to drive the first material distribution plate 13 to move and separate the first workpieces 10 one by one. The first material distribution plate 13 is provided with a first positioning groove 131 for positioning the first workpiece 10.

[0034] The second assembly platform 2 includes a second support plate 21, a second material distribution base 22 disposed on the second support plate 21 and used for docking with the second feeding mechanism 5, a first positioning groove plate 23 disposed on the second material distribution base 22 and used for positioning the first workpiece 10, a second material receiving sensor 24 disposed on the second material distribution base 22 and used for detecting the second workpiece 20, and a second cylinder 25 disposed below the second material distribution base 22 and used for pushing the second workpiece 20 into the first workpiece 10. The first positioning groove plate 23 is provided with a first positioning hole 231 located on the second workpiece 20 and used for positioning the first workpiece 10.

[0035] The third assembly platform 3 includes a fourth support plate 31, a third material distribution base 32 disposed on the fourth support plate 31 and used for docking with the third feeding mechanism 6, a third material distribution plate 33 slidably disposed in the third material distribution base 32 and perpendicular to the end of the third feeding mechanism 6 to receive the third workpiece 30, a third material sensor 34 disposed on the third material distribution base 32 and used for detecting the third workpiece 30, a third positioning groove plate 35 disposed on the third material distribution base 32 and used for positioning the first workpiece 10, and a fourth cylinder 36 used to drive the third material distribution plate 33 to move and separate the third workpieces 30 one by one. The third material distribution plate 33 is provided with a second positioning groove 331 for positioning the third workpiece 30, and the third positioning groove plate 35 is provided with a third positioning hole 351 for positioning the first workpiece 10.

[0036] In summary, during operation, the first feeding mechanism 4, the second feeding mechanism 5, and the third feeding mechanism 6 respectively transfer the first workpiece 10, the second workpiece 20, and the third workpiece 30 to the first assembly table 1, the second assembly table 2, and the third assembly table 3. Further, the first assembly table 1 separates the first workpiece 10 one by one for the conveying mechanism 7 to grasp, and then the conveying mechanism 7 moves the first workpiece 10 to the second assembly table 2. Further, the second assembly table 2 positions the first workpiece 10 above the second workpiece 20, and then the second cylinder 25 pushes the second workpiece 20 upwards into the first workpiece 10. At this time, the conveying mechanism 7 remains pressed against the first workpiece 10; conversely, the second workpiece 20 pushes the first workpiece 10 out. Furthermore, the conveying mechanism 7 picks up the first workpiece 10, after the second workpiece 20 has been assembled on the second assembly table 2, and transfers it to the pre-tightening fixture table 8. The pre-tightening fixture table 8 pushes the second workpiece 20 completely into the interior of the first workpiece 10. During this process, the conveying mechanism 7 maintains pressure on the first workpiece 10 to ensure a tight fit between the second workpiece 20 and the first workpiece 10. Furthermore, the conveying mechanism 7 transfers the first workpiece 10, which has been tightly assembled on the pre-tightening fixture table 8, to the third assembly table 30. The third assembly table 30 then positions the first workpiece 10 above the third workpiece 30, and the fourth cylinder 36 pushes the third workpiece 30 into the first workpiece 10, thus realizing the assembly of the first workpiece 10, the second workpiece 20, and the third workpiece 30. Of course, since the conveying mechanism 7 has four equally spaced picking claws 75 arranged side by side, and the four picking claws 75 can be located above the first assembly table 1, the second assembly table 2, the pre-tightening tooling table 8, and the third assembly table 3 at the same time, when the conveying mechanism 7 picks up the first workpiece 10 on the first assembly table 1 and moves it to the second assembly table 2, the first workpiece 10 combined with the second workpiece 20 on the second assembly table 2 is also picked up and transferred to the pre-tightening tooling table 8 at the same time. Similarly, the assembly of the first workpiece 10 and the second workpiece 20 after being tightly fitted on the pre-tightening tooling table 8 is also picked up and transferred to the third assembly table 3 at the same time. And the assembly of the third workpiece 30 and the first workpiece 10 after being assembled on the third assembly table 3 is picked up and transferred at the same time. Thus, the first assembly table 1, the second assembly table 2, the pre-tightening tooling table 8, and the third assembly table 3 can work synchronously and the workpieces can be transferred synchronously, thereby greatly improving production efficiency.

[0037] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
