[0031] The limit assembly 4 includes a limit mounting seat 41, on which a rotary clamping cylinder 42 is provided, an adjustable oil pressure buffer 43 is provided above the rotary clamping cylinder 42, and an exhaust throttle valve 44 is provided below; the rotary clamping cylinder 42 can fix the rotary assembly 2 by clamping the block 25 installed on the upper welding seat 23.

[0032] The upper welding seat 23 is an elliptical structure. The upper shield 14 is symmetrically arranged on both sides of the upper welding seat 23 to form a circular structure with the upper welding seat 23 and can rotate with the slewing bearing 22 .

[0033] The mounting groove 30 is arranged directly below the through hole 24 , and the blocking block 32 and the welding clamping block 33 can move up and down along the mounting groove 30 and the through hole 24 , so that the blocking block 32 and the welding clamping block 33 can clamp the bottom of the overhead rail trolley.

[0034] The working principle and working process of the present invention are as follows:

[0035] During the working process, the overhead track vehicle 01 goes through each process one by one along the overhead track. Figure 1 As shown: the ceiling rail is a track structure installed on the ceiling of the workshop, with a ring connector under the ceiling rail, a pulley between the ring connector and the ceiling rail, and a ceiling rail trolley suspended under the ring connector. The ceiling rail trolley 01 is a frame structure used to hold the material tray, and a frame is set at the bottom to facilitate the clamping assembly 3 to clamp it through the frame; the ceiling rail trolley 01 can be dragged manually or electrically and slide forward along the ceiling rail.

[0036] like Figure 3 , Figure 4 As shown: first, the rotary clamping cylinder 42 of the front lower limit assembly 4 is used to clamp the rotary assembly 2, that is, the rotary clamping cylinder 42 contracts and rotates, and the stopper head connected to the end of the rotary clamping cylinder 42 and the adjustable oil pressure buffer 43 work together to clamp the stopper 25 installed on the upper welding seat 23, so that the rotary assembly 2 no longer rotates; at this time, the bottom of the overhead rail trolley 01 is parallel to the upper retaining edge 16, and when the overhead rail trolley 01 moves along the overhead rail, the bottom of the overhead rail trolley 01 slides forward along the upper retaining edges 16 on the left and right sides of the upper part of the frame assembly 1, and the upper retaining edges 16 limit the overhead rail trolley from shaking left and right;

[0037] like Figure 5 , Figure 6 As shown, the clamping cylinder 34 of the clamping assembly 3 controls the welding clamping block 33 to rotate around the rotating shaft 302, and the lifting cylinder 35 controls the blocking block 32 to move up and down.

[0038] After the photoelectric sensor on the frame assembly 1 senses that the overhead rail trolley is in place, the electric control system controls the lifting cylinder 35 to lift the blocking block 32, and the clamping cylinder 34 is retracted, driving the welding clamping block 33 to move to the left. The welding clamping block 33 and the blocking block 32 jointly clamp the bottom frame of the overhead rail trolley 01. At this time, the positioning of the overhead rail trolley 01 is completed, and the automation equipment of the subsequent process can take and place materials;

[0039] After the material is taken in and placed, the rotary clamping cylinder 42 of the front limit assembly 4 releases the stopper 25, so that the rotary support 22 of the rotary assembly 2 can rotate to another angle with the overhead rail trolley 01. The rotation angle can be limited by the electronic control system, and the rotation deceleration is controlled by the signal of the proximity switch during the rotation; after the rotary assembly 2 rotates a certain angle, it hits the adjustable oil pressure buffer 43 of the rear lower limit assembly 4 and stops rotating. Subsequently, the rotary clamping cylinder 42 of the rear lower limit assembly 4 clamps the stopper 25 installed on the upper welding seat 23 through the stopper head and the adjustable oil pressure buffer 43 connected at its end, thereby clamping the rotary assembly 2 so that it no longer rotates. At this time, the rotary assembly completes the positioning again, and the automation equipment of the subsequent process can take and place materials;

[0040] After the material is taken and placed, the rotary assembly can be rotated back to the original direction along the original path with the overhead rail trolley 01. During the rotation, the rotation deceleration is controlled by the signal of the proximity switch. The rotary assembly 2 stops rotating after hitting the adjustable oil pressure buffer 43 of the front lower limit assembly 4. Subsequently, the rotary clamping cylinder 42 of the front lower limit assembly 4 works together through the stop head and the adjustable oil pressure buffer 43 connected at its end to clamp the stop block 25 installed on the upper welding seat 23, thereby clamping the rotary assembly 2 so that it will not rotate. At this time, the rotary assembly completes the positioning again, and the clamping cylinder 34 extends out, driving the welding clamping block 33 to rotate around the rotating shaft 302. The welding clamping block 33 and the stop block 32 release the overhead rail trolley 01, and the lifting cylinder 35 is controlled by the manual switch to lower the stop block 32. At this time, the overhead rail trolley 01 can continue to move forward to the next process along the overhead rail.

[0041] The present invention can overcome the problem that the positioning accuracy of the overhead rail trolley 01 is low and it is difficult to pick up and place all the materials on the overhead rail trolley in 360 degrees, and can realize accurate picking and placing of materials on the overhead rail trolley 01, and maximize the use of all 360-degree space of the overhead rail material trolley to realize the automation of material picking and placing.

[0042] After the overhead rail trolley 01 reaches the specified position, the clamping and positioning device of the present invention clamps the overhead rail trolley 01 by the side guard 15, the upper guard 16 and the clamping assembly 3 to ensure its positioning accuracy in the horizontal direction, so as to facilitate the accurate picking and placing of materials by the automated equipment in the subsequent process; when the overhead rail trolley 01 rotates to a specific angle, the clamping and positioning device of the present invention can rotate with the overhead rail trolley 01 while keeping the clamped overhead rail trolley 01, and then the device positions and locks itself to ensure the positioning accuracy of the overhead rail trolley 01, and the automated equipment in the subsequent process can pick up and place materials on the other side of the trolley.

[0043] The present invention improves the degree of automation in the logistics and transportation process, improves working conditions, avoids personal accidents, improves production efficiency, and reduces logistics and transportation costs; the entire process is safe, reliable, fast and efficient, and can be widely promoted and used in the logistics and transportation industry where the handling space is small, the material picking and placing accuracy must be guaranteed, and the workload is heavy.

[0044] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
