Detailed Description

As shown in fig. 1, the arc-changing device for producing curved toughened glass of the present invention mainly comprises a plate-assembling mechanism, a main link mechanism and an auxiliary link mechanism.

The plate set mechanism comprises a plurality of T-shaped plates 1, and any one T-shaped plate 1 is provided with two wing parts at two sides and a base part below the two wing parts. All the T-shaped plates 1 are sequentially hinged and connected in series into a whole through wing parts. Wherein the base of one T-shaped plate 1 positioned in the middle is fixedly supported by a fixed seat 8, and the two T-shaped plates 1 positioned at the two ends are respectively provided with a lifting point 2 which can be respectively connected with a lifting mechanism, so that the two lifting points 2 can be respectively acted on in the same direction by an oil cylinder, an air cylinder or other lifting mechanisms, and the plate group mechanism is integrally bent into an arc.

The main link mechanism is distributed at the lower side of the base parts of the T-shaped plates 1, is in the shape of an X-shaped expansion bracket distributed along the length direction of the plate group mechanism and comprises a plurality of first links 7 with equal length. The first connecting rods 7 are connected in pairs in a crossed, staggered and hinged mode, and the two ends of any one first connecting rod 7 are provided with first hinge pins 5 for hinging. A first pin shaft 5 at one end of the same first connecting rod 7 is rotatably arranged in a first shaft hole arranged at the lower position of the base part of the T-shaped plate 1, a first pin shaft 5 at the other end is slidably arranged in a sliding groove 6 arranged on the base part of the T-shaped plate 1, and the sliding groove 6 is arranged along the length direction of the base part.

The auxiliary connecting rod mechanisms are distributed on the base part of the T-shaped plate 1 and are positioned above the main connecting rod mechanisms, the auxiliary connecting rod mechanisms are in the same X-shaped telescopic frames distributed along the length direction of the plate group mechanism and comprise a plurality of second connecting rods 4 with equal length, and the length of each second connecting rod 4 is smaller than that of each first connecting rod 7. The second connecting rods 4 are connected in pairs in a crossed, staggered and hinged mode, and the two ends of any one second connecting rod 4 are provided with second hinge pins 3 for hinging. The second pin shaft 3 at one end of the same second connecting rod 4 is rotatably arranged in a second shaft hole arranged on a first connecting rod 7 at the corresponding position, and the second pin shaft 3 at the other end is also slidably arranged in the chute 6.

The utility model discloses when becoming the arc motion, as shown in FIG. 2. T-shaped plate 1 that is located both ends is pulled up by lifting mechanism through lifting point 2, the one end of first connecting rod 7 uses the first round pin axle 5 of corresponding side to rotate as the center, the other end uses the first round pin axle 5 of corresponding side to rotate as the center, and wherein one end is linear motion in spout 6. there is the second shaft hole on the first connecting rod 7, second connecting rod 4 one end is passed through the second round pin axle 3 of corresponding side and is used the second shaft hole as the center rotation, the other end passes through the second round pin axle 3 of corresponding side to rotate as the center, and can be linear motion in spout 6. due to main link mechanism and supplementary link mechanism's mating reaction when non-fixed T-shaped plate 1 rotates, drive all non-fixed T-shaped plate 1 and rotate simultaneously, make contained angle α between each T-shaped plate 1 approximately equal to β approximately equal to gamma, form the circular arc that one section radius is R.
