Example one
Referring to fig. 1, the door frame turnover mechanism provided in this embodiment structurally includes a frame 1 fixedly installed on a floor of a factory, and supporting and stabilizing the frame, wherein a first turnover frame 2 and a second turnover frame 3 are installed on the frame 1. When the first roll-over stand 2 and the second roll-over stand 3 are in initial states, the first roll-over stand 2 and the second roll-over stand 3 are in the same plane on the frame 1, and projections of the first roll-over stand 2 and the second roll-over stand 3 along a front view projection plane V plane are mutually crossed in the process of turning over the door frame. When the first roll-over stand 2 and the second roll-over stand 3 are provided with the stop dog 6 at the end of the opposite ends, the stop dog 6 can prevent the door frame from sliding out of the roll-over stands (the first roll-over stand 2 and the second roll-over stand 3) and falling off due to self gravity in the process of turning over the door frame. The first roll-over stand 2 and the second roll-over stand 3 are rotatably connected with the frame 1 through two groups of roll-over assemblies 8. It should be noted that, in order to ensure the door frame turning process, the distance between the respective connection points of the first roll-over stand 2 and the second roll-over stand 3 on the frame 1 and the frame 1 should be greater than the distance between the stop 6 on each roll-over stand (the first roll-over stand 2 and the second roll-over stand 3) and the turning assembly 8, and meanwhile, the minimum included angle between the first roll-over stand 2 and the second roll-over stand 3 when the projections along the front projection plane V-plane intersect each other should be an acute angle.
Referring to fig. 2, a first air cylinder 7 is connected between the first roll-over stand 2 and the frame 1, a second air cylinder 5 is connected to the second roll-over stand 3 and the frame 1, the first air cylinder 7 is fixedly connected (bolted or welded) with the frame 1 and the first roll-over stand 2 through other parts, the bottom and the top of the first air cylinder 7 can rotate relative to the frame 1 and the first roll-over stand 2, and the first roll-over stand 2 is controlled to roll over by setting a fixed stroke for the first air cylinder 7. In the same way, the second cylinder 5, the second roll-over stand 3 and the rack 1 form a revolute pair, and the second roll-over stand 3 is controlled to be matched with the first roll-over stand 2 to realize turning. Accordingly, the turning angle range of the first turning frame 2 and the second turning frame 3 controlled by the air cylinder does not exceed 90 degrees.
Simultaneously, still be connected with the third cylinder 4 that is used for assisting the door frame upset on second roll-over stand 3, third cylinder 4 is located the one end that has dog 6 of keeping away from on second roll-over stand 3, and it should be noted that, the interval between dog 6 on third cylinder 4 and the second roll-over stand 3 should with the door frame size looks adaptation that overturns, ensures that the piston rod of third cylinder 4 can contact with the door frame promptly and promote the door frame. In the door frame upset in-process, the door frame is carried to second roll-over stand 3 and first roll-over stand 2 slowly rotates in opposite directions, and when two roll-over stands were in the state of crisscross each other and its contained angle along the V face projection was the minimum, the piston rod of third cylinder 4 pushed up the door frame slowly, when treating the door frame and crossing the critical point of vertical state, the door frame deflected to first roll-over stand 2 under the dead weight. In the process, the distance between the two groups of turning assemblies 8 on the rack 1 is not less than the distance from the stop block 6 to each corresponding group of turning assemblies 8, and the minimum included angle between the first turning frame 2 and the second turning frame 3 when the projection along the V surface is intersected is an acute angle so as to ensure that the door frame can be from the second turning frame 3 to the first turning frame 2.
The two groups of turning assemblies 8 connected with the machine frame 1 have the same structure and are composed of a rotating shaft 801, a bearing seat 802, a bearing 803 and a cantilever bracket 804 for connecting the machine frame 1 and the turning assemblies 8.
Specifically, referring to fig. 3, the cantilever mount 804 is fixedly connected to the top of the frame 1, an arc surface is formed on the cantilever mount 804, and the rotating shaft 801 is welded in the arc surface of the cantilever mount 804. Bearings 803 (rolling bearings or sliding bearings) are assembled on the rotating shaft 801 near the two ends, the bearings 803 are assembled on the bearing seats 802, and the bottom surfaces of the bearing seats 802 are fixedly connected with the roll-over frames (the first roll-over frame 2 and the second roll-over frame 3) through bolts.
This kind of door frame tilting mechanism that this scheme provided through the rotation of its cylinder with pivot 801 control roll-over stand to realize the automatic turn-over of door frame in the course of working, improved door frame machining efficiency, reduced intensity of labour. In addition, the servo motor in the traditional mechanism is replaced by the air cylinder to provide the moment required by the mechanism for overturning the door frame, and a speed reducing mechanism is omitted, so that the structure is simplified, the whole size of the mechanism is smaller, and the manufacturing cost is lower. Meanwhile, the structure of the mechanism is simplified, the whole size is small, and the factory installation and construction cost is lower.
