The increase in labor costs will make the degree of automation of automobile production lines higher and higher. Transportation is the basis of all automation. Only when the workpieces are automatically transported between different stations on the production line can the automation of the production line be realized. Therefore, my country's automobile industry has a very large demand for automated conveying equipment.
[0003] The accumulation and release chain is a kind of transportation equipment used in the body-in-white welding workshop of automobile main engine factories.

DETAILED DESCRIPTION
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0024] Reference Figure 1-3As shown, the cornering buffer mechanism of the accumulation chain of the utility model comprises: a fixed block 1, a buffer block 2, a buffer spring 3, a brake paddle 4 and a connecting spring 5; the fixed block 1 is fixedly arranged on the frame of the accumulation chain; the buffer block 2, one end of which is connected to the fixed block 1 by a rotating shaft, and a buffer spring 3 is arranged between the other end of the buffer block 2 and the fixed block 1, the upper end of the buffer block 2 is provided with a limiting groove 21, the limiting groove 21 is used to stop the conveying trolley, and the buffer spring 3 is used for buffering of the buffer block 2; the brake paddle 4 is connected to the buffer block 2 by a rotating shaft, and a connecting spring 5 is arranged between the lower end of the brake paddle 4 and the buffer block 2, the connecting spring 5 is used to provide elastic restoring force for the brake paddle 4, the brake paddle 4 is used to block the conveying trolley, and when the brake paddle 4 is moved, it is used to move the conveying trolley into the limiting groove 21.
[0025] The driving chain drives the conveyor trolley to move to the bending position, and the conveyor trolley is blocked by the brake paddle 4. As the driving chain rotates, the brake paddle 4 is pushed to release the blockage of the conveyor trolley, and the conveyor trolley follows the driving chain to move, and the conveyor trolley moves to the limiting groove 21. Since the limiting groove 21 is lower than the upper end surface of the buffer block 2, the conveyor trolley is stopped in the limiting groove 21, that is, the conveyor trolley stops at the bending position. As the rotating disc connected to the rotating shaft on the accumulation chain rotates, the conveyor trolley is driven to flip by the telescopic pin of the rotating disc, thereby pulling the conveyor trolley out of the limiting groove 21, and the conveyor trolley releases the brake, so as to continue to move with the driving chain, so as to achieve deceleration and braking of the conveyor trolley at the bending position, and turn the bending position at a low speed, thereby ensuring the safety of the movement of the conveyor trolley.
[0026] In the above structure, a rotating shaft 16 is provided between one end of the buffer block 2 and the fixed block 1, and the buffer block 2 is hinged to the fixed block 1 through the rotating shaft 16. The rotating shaft 16 is located on the side of the buffer block 2 close to the direction in which the conveying trolley enters, so that after the conveying trolley enters the buffer block 2, the buffer spring 3 is pressed down to brake and buffer the conveying trolley. A rotating shaft 27 is provided between the middle position of the brake paddle 4 and the buffer block 2, and the brake paddle 4 is hinged to the buffer block 2 through the rotating shaft 27, and the brake paddle 4 forms a seesaw structure with the rotating shaft 27 as the center. The brake paddle 4 forms a seesaw structure around the rotating shaft 27, and pressing one end of the brake paddle 4 can cause the other end of the brake paddle 4 to tilt up, and the connecting spring 5 provides an elastic restoring force for the brake paddle 4 to reset, so that the brake paddle 4 can work repeatedly.
[0027] In order to prevent the brake paddle 4 from tilting too much during the process of being tilted, causing the conveying trolley to deviate from the track, a brake pin 22 is provided on the buffer block 2, and a brake groove 41 is provided on the upper end of the brake paddle 4. When the brake pin 22 is set in the brake groove 41, it is used to lock the brake paddle 4. The brake pin 22 abuts against the inner wall of the brake groove 41, and the brake pin 22 will not move at this time, thereby limiting the rotation angle of the brake paddle 4. An arcuate surface 1 42 is provided on the upper end of the brake paddle 4, and the brake pin 22 contacts the arcuate surface 1 42, and one end of the arcuate surface 1 42 is connected to one end of the brake groove 41.
[0028] In the above structure, the fixed block 1 is provided with a second limiting groove 11, and when the buffer spring 3 provides elastic restoring force, the buffer block 2 is braked in the second limiting groove 11. The position of the buffer block 2 is limited by the provided second limiting groove 11, thereby ensuring that when the buffer block 2 is in a normal state, the transport trolley can stably drive into the first limiting groove 21.
[0029] In the above structure, the buffer block 2 is a right-angle plate, and one right-angle end of the buffer block 2 is connected to the fixed block 1 via a rotating shaft. A notch 23 is provided at the right-angle corner of the buffer block 2, and the buffer spring 3 is connected to the end face at the notch 23.
[0030] In the above structure, the upper end surface of the buffer block 2 is provided with an arcuate transition surface 24, the arcuate transition surface 24 is located on the side of the buffer block 2 facing the conveying start end, and the arcuate transition surface 24 is connected to the limiting groove 1 21. A limiting convex portion 25 is provided between the limiting groove 1 21 and the upper end surface of the buffer block 2. The arcuate transition surface 24 is a transition that gradually tilts upward from the driving end of the conveying trolley to the limiting groove 1 21, so that the conveying trolley can stably enter the limiting groove 1 21 along the arcuate transition surface 24.
[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
