Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a stopper device. Background Technology
[0002] In the conveying system of the welding, painting and final assembly workshop of automobile production, it is necessary to realize the transfer of multiple models at the handover station. During the transfer process, after the trolley moves the frame into place, a clamping mechanism is needed to clamp and fix the bottom of the frame. Since the clamping mechanism is driven by a servo electric cylinder, the trolley will continue to move forward due to inertia during clamping, which will cause impact on the servo electric cylinder and reduce the service life of the servo electric cylinder. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a blocking device that blocks the trolley after the trolley conveyor frame is in place, thereby avoiding impact on the servo electric cylinder, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a blocking device, comprising a blocking assembly, wherein the blocking assembly is disposed opposite to a clamping mechanism, and the blocking assembly comprises a support mechanism, a mounting bracket, a cylinder, a sealing plate, a first V-block, a hinge seat, a connecting block, a second V-block, a rotating shaft, and a stop block;
[0005] The support mechanisms are symmetrically arranged on the ground. The mounting frame is fixed between the two support mechanisms. The cylinder is installed on the upper end of the mounting frame. The sealing plates are symmetrically fixed on both sides of the mounting frame. The telescopic rod of the cylinder is hinged to the lower end of one side of the first V-block. The lower end of the other side of the first V-block is hinged to the hinge seat. The hinge seat is installed on the upper end of the mounting frame. The upper end of the first V-block is hinged to the lower end of the connecting block. The upper end of the connecting block is hinged to the lower end of the second V-block. The upper end of one side of the second V-block is fixedly connected to the stop block. The upper end of the other side of the second V-block is rotatably connected to the outer side of the rotating shaft. The rotating shaft is rotatably connected between the two sealing plates.
[0006] As a preferred embodiment of this utility model, the upper end of the mounting bracket is provided with a mounting block, and the fixed end of the cylinder is hinged to the mounting block.
[0007] In a preferred embodiment of this invention, the opening of the first V-shaped block faces downwards, and the opening of the second V-shaped block faces upwards.
[0008] In a preferred embodiment of this utility model, the telescopic rod of the cylinder is connected to a hinge joint, and the hinge joint is hinged to the first V-block.
[0009] As a preferred embodiment of this utility model, a limiting rod is provided on one side of the rotating shaft, and the limiting rod is fixed between the two sealing plates.
[0010] As a preferred embodiment of this utility model, a sensing pin is provided at the hinge joint between the second V-shaped block and the connecting block.
[0011] As a preferred technical solution of this utility model, the support mechanism includes a base, a vertical plate, a connecting plate, an adjusting nut, a screw, and a connecting frame. The vertical plates are symmetrically fixed to the upper end of the base. The screw is fixed to the base and located between the two vertical plates. The connecting plate is sleeved on the outer side of the screw. There are two adjusting nuts, which are threadedly connected to the screw and located on the upper and lower sides of the connecting plate, respectively. One side of the connecting plate is fixedly connected to the connecting frame, and the mounting frame is fixed to the connecting frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the stopper device is reasonably designed and ingeniously conceived. After the trolley is transported to the position, the first V-block is rotated by the cylinder, which in turn drives the connecting block and the second V-block to rotate. The stop block on the second V-block swings upward and contacts the trolley, preventing the trolley from continuing to move forward due to inertia. This ensures that the clamping mechanism can stably clamp the frame, protect the servo cylinder from impact, and extend the service life of the servo cylinder. Attached Figure Description

[0019] Support mechanisms 11 are symmetrically arranged on the ground. Mounting brackets 12 are fixed between the two support mechanisms 11. Cylinders 13 are horizontally mounted on the upper end of the mounting brackets 12. Sealing plates 14 are symmetrically fixed on both sides of the mounting brackets 12. The opening of the first V-block 16 faces downwards. The telescopic rod of the cylinder 13 is hinged to the lower end of one side of the first V-block 16. The lower end of the other side of the first V-block 16 is hinged to a hinge seat 17, which is mounted on the upper end of the mounting bracket 12. The upper end of the first V-block 16 is hinged to the lower end of a connecting block 18. The opening of the second V-block 19 faces upwards. The upper end of the connecting block 18 is hinged to the lower end of the second V-block 19. The lower end of the second V-block 19 is hinged, and the upper end of one side of the second V-block 19 is fixedly connected to the stop block 21. The upper end of the other side of the second V-block 19 is rotatably connected to the outer side of the rotating shaft 20. The rotating shaft 20 is rotatably connected between the two sealing plates 14. Through the extension and retraction of the cylinder 13, the first V-block 16 is driven to rotate. The first V-block 16 drives the connecting block 18 to rotate. The connecting block 18 drives the second V-block 16 to rotate. The second V-block 16 drives the stop block 21 to swing upward. The stop block 21 blocks the trolley and prevents the trolley from impacting the servo cylinder, thereby protecting the servo cylinder from damage.
[0020] To protect the cylinder 13 from damage during the extension process, a mounting block 24 is provided at the upper end of the mounting bracket 12, and the fixed end of the cylinder 13 is hinged to the mounting block 24.
[0021] To facilitate the hinged connection between the telescopic rod of cylinder 13 and the first V-block 16, the telescopic rod of cylinder 13 is connected to the hinge joint 15, and the hinge joint 15 is hinged to the first V-block 16.
[0022] To prevent the stop block 21 from swinging out of position, a limit rod 22 is provided on one side of the rotating shaft 20, and the limit rod 22 is fixed between the two sealing plates 14.
[0023] To facilitate the positioning of the sensing trolley, a sensing pin 23 is provided at the hinge between 19 and the connecting block 18. The sensing pin 23 works in conjunction with the sensing switch on the trolley to sense the position.
[0024] To facilitate height adjustment of the device, the support mechanism 11 includes a base 111, a vertical plate 112, a connecting plate 113, an adjusting nut 114, a screw 115, and a connecting frame 116.

The mounting frame 12 is fixed on the connecting frame 116. By adjusting the height position of the connecting plate 113, the height of the connecting frame 116 is adjusted, and by tightening the two adjusting nuts 114, the swing height of the stop block 21 is increased.
[0025] In use: When the trolley moves the frame to the stopping point, the induction switch on the trolley senses the induction pin 23 and controls the cylinder 13 to extend through the control system. The cylinder 13 drives the first V-block 16 to swing, the first V-block 16 drives the connecting block 18 to swing, and the connecting block 18 drives the second V-block 19 to swing, thereby swinging the end of the stop block 21 upward to block the trolley.
