Description

Technical Field

[0001] This utility model mainly relates to the field of torsion damper processing technology, specifically to an automatic bolt installation mechanism for torsion dampers. Background Technology

[0002] The working principle of torsional dampers is mainly based on mechanisms such as springs, dampers, and friction. When the system is subjected to torsional vibration, the springs and dampers inside the torsional damper will start to work, absorbing and dissipating vibration energy. At the same time, some torsional dampers also use slippage between friction plates or friction surfaces to limit the transmission of torque, thereby preventing system overload.

[0003] The structural composition of a torsion damper varies depending on the application and design requirements, but it typically includes a torsion bar, damper, spring, friction plate, and other components. After the relevant components are assembled together, they need to be protected by a protective housing to form a complete torsion damper.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] Current torsion dampers require a protective housing to connect all internal components together with bolts. Therefore, all bolts on the housing need to be tightened. Generally, torsion dampers are equipped with at least six bolts. Manual tightening is inefficient and labor-intensive.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0008] This utility model provides an automatic installation mechanism for bolts of a torsion damper, which solves the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: an automatic installation mechanism for torsion-limiting vibration damper bolts, including a bolt feeding mechanism. A worktable is provided on the side of the bolt feeding mechanism. First tracks are symmetrically arranged on both sides of the top of the worktable. A second track is slidably connected to the top of the first tracks. First drive mechanisms are symmetrically arranged on both sides of the second tracks. The first drive mechanisms are respectively connected to a moving lifting mechanism. A bolt tightening mechanism is connected to the side of the moving lifting mechanism. A placement groove is provided in the middle of the worktable. A lifting device is matched and connected to the bottom of the placement groove. This device can perform bolt installation operations on initially assembled torsion-limiting vibration damper bolts. During operation, the torsion-limiting vibration damper is placed in the placement groove... The bolt is positioned in the slot, and the lifting device moves the torsion damper downward a certain distance. Then, the bolt feeding mechanism sends the bolt to the preset position. The first drive mechanism moves the second track to the top of the bolt. The moving lifting mechanism moves the bolt tightening mechanism downward, and the bolt tightening mechanism magnetically holds the corresponding bolt. Then, the moving lifting mechanism lifts the bolt, and the first track moves the bolt tightening mechanism to the preset position. Then, the moving lifting mechanism moves the bolt tightening mechanism down to the mounting hole of the torsion damper, and the installation operation can be carried out. Then, the bolt tightening mechanism, with the cooperation of the first and second tracks, performs the material picking and installation operation again. This device has a high degree of automation and can effectively improve the bolt installation efficiency of the torsion damper.

[0011] Furthermore, the bolt feeding mechanism is provided with a feeding device at its end. The feeding device includes a concave support block. A first telescopic cylinder is connected to the outside of the concave support block. The first telescopic cylinder is connected to an L-shaped material transfer block. The L-shaped material transfer block is slidably connected to the top of the concave support block. A receiving groove is opened on the inner side of the concave support block. The receiving groove corresponds to the bolt. The bolt feeding mechanism has a storage notch on the side corresponding to the concave support block.

[0012] Furthermore, a first concave groove is formed at the top of the first track, and a first rotating screw is provided in the first concave groove, which is connected to the second track.

[0013] Furthermore, the second track has symmetrically formed second concave grooves on its side, which are matched and connected to the movable lifting mechanism. The second track also has a moving groove on its side, in which second rotating screws are symmetrically arranged. The ends of the second rotating screws are respectively connected to the first driving mechanism, and the second rotating screws are matched and connected to the movable lifting mechanism.

[0014] Furthermore, the movable lifting mechanism includes a mounting plate, which is slidably connected to the second track and matched with the second rotating screw. A support member is connected to the rear side of the mounting plate, and a second telescopic cylinder is connected to the top of the support member. A connecting plate is connected to the top of the second telescopic cylinder, and a bolt tightening mechanism is connected to the side of the connecting plate. A lifting block is also provided on the side of the bolt tightening mechanism and slidably connected to the side track of the mounting plate.

[0015] Furthermore, the lifting device includes a hydraulic lifting mechanism, the top of which is connected to a support plate. The support plate has multiple connection holes, and positioning pins are matched and connected to the connection holes. The positioning pins are matched and connected to the bottom of the torsion damper.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This utility model is reasonably designed. By using a bolt feeding mechanism in conjunction with a movable bolt tightening mechanism, the bolt installation work can be automatically carried out during the installation of the housing of the torsion damper, which improves the bolt installation efficiency and reduces labor costs.

[0031] See attached document Figure 1-4 An automatic installation mechanism for torque-limiting vibration damper bolts includes a bolt feeding mechanism 1. A worktable 2 is provided on the side of the bolt feeding mechanism 1. First tracks 3 are symmetrically arranged on both sides of the top of the worktable 2. A second track 4 is slidably connected to the top of the first tracks 3. First drive mechanisms 5 are symmetrically arranged on both sides of the second track 4. The first drive mechanisms 5 are respectively connected to a moving lifting mechanism 6. A bolt tightening mechanism 7 is connected to the side of the moving lifting mechanism 6. A placement groove 8 is provided in the middle of the worktable 2. A lifting device 9 is matched and connected to the bottom of the placement groove 8. This device can perform bolt installation operations on pre-assembled torque-limiting vibration damper bolts. During operation, the torque-limiting vibration damper is placed and positioned in the placement groove 8, and the lifting device... The device 9 moves the torsion damper downward a certain distance, and then the bolt feeding mechanism 1 sends the bolt to the preset position. The first drive mechanism 5 drives the second track 4 to move to the top of the bolt. The moving lifting mechanism 6 drives the bolt tightening mechanism 7 to descend. The bolt tightening mechanism 7 magnetically holds the corresponding bolt. Then the moving lifting mechanism 6 lifts up, and the first track 3 drives the bolt tightening mechanism 7 to the preset position. Then the moving lifting mechanism 6 drives the bolt tightening mechanism 7 to descend to the mounting hole of the torsion damper, and the installation operation can be carried out. Then the bolt tightening mechanism 7, with the cooperation of the first track 3 and the second track 4, performs the material picking and installation operation again. This device has a high degree of automation and can effectively improve the bolt installation efficiency of the torsion damper.

[0032] The bolt feeding mechanism 1 is provided with a feeding device 11 at its end. The feeding device 11 includes a concave support block 12. The outer side of the concave support block 12 is connected to a first telescopic cylinder 13. The first telescopic cylinder 13 is connected to an L-shaped material transfer block 14. The L-shaped material transfer block 14 is slidably connected to the top of the concave support block 12. The inner side of the concave support block 12 has a receiving groove 15, which corresponds to the bolt. The bolt feeding mechanism 1 has a storage notch 16 on the side corresponding to the concave support block 12. The bolt feeding mechanism 1 can use existing technologies such as vibratory feeder feeding or manual feeding, which will not be elaborated here. The storage notch 16 corresponds to the feeding end of the bolt feeding mechanism 1. After the bolt is fed into the receiving groove 15, the first telescopic cylinder 13 on the side extends outward. Due to the limiting of the receiving groove 15 and the abutment of the bolt behind it, the bolt in the receiving groove 15 will move outward until it reaches the corresponding storage notch 16. At this time, the overall notch is larger than the bottom of the bolt, which facilitates the magnetic adsorption of the bolt tightening mechanism 7 at the top.

[0033] The first track 3 has a first concave groove 31 at the top, and a first rotating screw 32 is provided in the first concave groove 31. The first rotating screw 32 is connected to the second track 4. The first rotating screw 32 can drive the second track 4 to reciprocate on the first track 3, thereby moving the bolt towards the placement groove 8 through the bolt feeding mechanism 1.

[0034] The second track 4 has symmetrically opened second concave grooves 41 on its side, which are matched and connected to the movable lifting mechanism 6. The second track 4 also has a movable groove 42 on its side, and a second rotating screw 43 is symmetrically arranged in the movable groove 42. The ends of the second rotating screw 43 are respectively connected to the first drive mechanism 5 and matched and connected to the movable lifting mechanism 6. The two first drive mechanisms 5 are respectively connected to the two movable lifting mechanisms 6 through the second rotating screw 43. Two bolts can be installed at one time, and the second rotating screw 43 can adjust the position of the movable lifting mechanism 6 in various directions, thereby installing bolts at different positions of the torsion damper. In this embodiment, the torsion damper has a set of evenly distributed mounting holes. The two bolt tightening mechanisms 7 pick up two bolts at a time. Through the movement and cooperation of the first track 3 and the second track 4, the two bolts are installed one side at a time, which further improves the work efficiency.

[0035] The movable lifting mechanism 6 includes a mounting plate 61, which is slidably connected to the second track 4 and matched with the second rotating screw 43. A support member 62 is connected to the rear side of the mounting plate 61, and a second telescopic cylinder 63 is connected to the top of the support member 62. A connecting plate 64 is connected to the top of the second telescopic cylinder 63, and the bolt tightening mechanism 7 is connected to the side of the connecting plate 64. The bolt tightening mechanism 7 is also provided with a lifting block 65 on the side of the mounting plate 61, which is slidably connected to the side track of the mounting plate 61. The bolt tightening mechanism 7 adopts existing technology and its principle is similar to that of an electric screwdriver. It can adsorb and rotate bolts for installation. Since it is existing technology, it will not be described in detail here. Under the action of the second telescopic cylinder 63, the bolt tightening mechanism 7 can slide up and down along the mounting plate 61 to complete the adsorption and installation of bolts.

[0036] The lifting device 9 includes a hydraulic lifting mechanism 91. The top of the hydraulic lifting mechanism 91 is connected to a support plate 92. The support plate 92 has multiple connecting holes 93. Positioning pins 94 are matched and connected to the connecting holes 93. The positioning pins 94 are matched and connected to the bottom of the torsion damper. When the torsion damper needs to be bolted, the torsion damper is placed on the support plate 92. The top of the support plate 92 is equipped with positioning pins 94, which are connected to the positioning holes at the bottom of the torsion damper to facilitate subsequent bolt tightening operations. The positioning pins 94 can be installed in different positions according to the different specifications of the torsion damper.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
