[0027] See also Figure 1-3 As shown, a positioning assembly 3 is provided between the side surface of the base body 1 and the inner side surface of the conveying track 2. Two groups of positioning assemblies 3 are provided. The two groups of positioning assemblies 3 are respectively located on both sides of the base body 1, and the two groups of positioning assemblies 3 are symmetrical with respect to the base body 1. Each group of positioning assemblies 3 includes a positioning groove 31 provided on the inner wall of the conveying track 2. The length of the positioning groove 31 is equal to the length of the conveying track 2. A plurality of trapezoidal positioning blocks 32 made of iron material are fixedly connected to the inner wall of the positioning groove 31 opposite to the base body 1. The larger end of each positioning block 32 is fixedly connected to the bottom wall, and the smaller end faces the side surface of the base body 1. The smaller end faces the side surface of the base body 1, and the smaller end is arranged in an arc shape.
[0028] See also Figure 1-4As shown, the larger ends of adjacent positioning blocks 32 abut against each other, and there is a positioning gap 33 between adjacent positioning blocks 32. The base body 1 is connected to a positioning plate 34 made of iron material through an elastic connecting component 6. Two positioning plates 34 are provided, and the two positioning plates 34 are symmetrical about the base body 1. The end of the positioning plate 34 away from the base body 1 is inclined toward the precision block 35. The end of the positioning plate 34 away from the base body 1 is integrally connected with a precision block 35 made of iron material. The precision block 35 is inserted into the positioning gap 33. Each precision block 35 is semi-cylindrical, and the precision block 35 abuts against the positioning block 32. The end of the precision block 35 abuts against the inner wall of the positioning groove 31.
[0029] See also Figure 1-4 As shown, the elastic connection component 6 includes a second connection groove 61 opened on the base body 1, and the second connection groove 61 is provided with a rotation shaft 62. The positioning plate 34 is rotatably connected in the second connection groove 61 through the rotation shaft 62.

When the smaller end of 32 abuts, the positioning plate 34 rotates, the connecting spring 63 is stretched to generate elastic force, and when the precision block 35 is repositioned above the positioning gap 33, the elastic force generated by the connecting spring 63 pulls the precision block 35 to quickly fall into the positioning gap 33, and the precision block 35 collides with the positioning block 32 and generates a sound, which can remind the worker that the base body 1 is displaced.

If it is not caused by the worker's operation, the sound generated can remind the worker and allow the worker to adjust the displacement of the base body 1, which is also a means to ensure the accurate displacement of the base body 1.
[0030] See also Figure 1-3As shown, a buffer assembly 4 is provided between the base body 1 and the suspension rod 11. The buffer assembly 4 includes a buffer hole 41 provided at the bottom of the base body 1. The suspension rod 11 is inserted into the buffer hole 41. The suspension rod 11 rotates in the buffer hole 41 through the rotating assembly 5. A buffer ring 42 is sleeved around the suspension rod 11. There are multiple buffer rings 42. The multiple buffer rings 42 are evenly arrayed along the suspension rod 11. A buffer spring 43 with a damper is fixedly connected to the outer wall of the buffer ring 42. The end of the buffer spring 43 with a damper away from the buffer ring 42 is fixedly connected to the inner wall of the buffer hole 41. A buffer sponge ring 44 is fixedly connected to the inner wall of the buffer ring 42. The inner wall of the buffer sponge ring 44 abuts against the circumferential outer wall of the suspension rod 11. The buffer assembly 4 provided can further resist inertia and vibration, reduce the influence of inertia on the docking position of the base body 1, and improve the running accuracy.
[0031] See also Figure 1-3 As shown, the rotating assembly 5 includes a rotating bearing 51, which is fixedly connected to the inner wall of the buffer hole 41. A rotating rod 52 is fixedly connected to the rotating bearing 51. A rotating hole 53 is opened at the end of the suspension rod 11. After the suspension rod 11 is inserted into the rotating bearing 51, the rotating rod 52 passes through the rotating hole 53.
[0032] A specific application of this embodiment is:
[0033] When using the vehicle, the worker first hangs the automobile parts on the suspension rod 11. When hanging, the rotating bearing 51 can support the suspension rod 11 to rotate 360 degrees, which improves the convenience of the worker. After hanging, the transport track 2 drives the base body 1, the suspension rod 11 and the automobile parts to move to the processing site.
[0034] When automobile parts are transported to the processing stage, workers operate the conveyor belt to drive the base body 1 to move. The base body 1 makes a sound during the movement. The workers judge the displacement amount and displacement speed of the base body 1 according to the sound. When the speed is high, the conveyor belt is operated to reduce the speed, which also reduces the inertia of the parts, so as to improve the stability of the displacement of the base body 1.
[0035] When the parts arrive at the designated position, the workers stop the conveyor belt, and the conveyor belt stops driving the base body 1. The auto parts generate inertia due to their own weight, and the inertia is first transmitted to the suspension rod 11. The buffer sponge ring 44 around the suspension rod 11 can buffer the impact force, and the buffer spring 43 with a damper can also buffer the impact force generated by the inertia. When the weakened inertia is transmitted to the base body 1, the base body 1 will transmit this movement trend to the positioning plate 34 and the precision block 35. Since the precision block 35 is inserted in the positioning gap 33, the positioning block 32 can provide a barrier for the precision block 35, so that the base body 1 is stable at the parking position, and the connection spring 63 is set when the positioning plate 34 has a displacement trend. The positioning plate 34 is tightened by its own elastic force, so that the precision block 35 stops in the current positioning gap 33. In addition, there are two groups of precision blocks 35 and positioning plates 34. The two groups of precision blocks 35 can simultaneously ensure the stability of the base body 1 and improve the resistance of the base body 1 to the inertial influence of auto parts. Meanwhile, if the worker finds that the base body 1 still makes a sound after the operation has been stopped, the position of the base body 1 can be adjusted to ensure the accuracy of the displacement of the base body 1. In summary, through the above steps, the effect of preventing the decrease of the conveying accuracy due to inertia is achieved.
[0036] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
