Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 and 2, a fabric clamping assembly of a frame stretching machine according to an embodiment of the present invention is shown. The utility model discloses a clamping component, including mounting panel 1, fixed plate 2, pinch-off blades 3, pivot 4 and die clamping cylinder 5, die clamping cylinder 5 articulate in 1 side of mounting panel, 3 one ends of pinch-off blades with die clamping cylinder 5 articulates, 4 one ends of pivot connect perpendicularly in 3 middle parts of pinch-off blades, 4 other ends of pivot rotate connect in 1 lower extreme of mounting panel, 2 fixed mounting of fixed plate in 1 lower extreme of mounting panel works as when die clamping cylinder 5 stretches out, 3 other ends of pinch-off blades with 2 butts of fixed plate. Because 3 middle parts of pinch-off blades link to each other with pivot 4, pivot 4 rotates and connects in mounting panel 1 below, consequently pinch-off blades 3 can only use the tie point of pivot 4 and mounting panel 1 as the centre of a circle, use pivot 4 as the radius rotation, die clamping cylinder 5 is articulated with the one end of pinch-off blades 3, for promoting die clamping blades 3 to rotate, die clamping cylinder 5 is articulated with mounting panel 1 to can not block between die clamping cylinder 5 and the pinch-off blades 3, guarantee die clamping cylinder 5 to the promotion of pinch-off blades 3. In this embodiment, the clamping cylinder 5 provides a downward pushing force to the clamping plate 3, the clamping plate 3 rotates, and the rotating shaft 4 is perpendicular to the clamping plate 3, so that the clamping plate 3 provides a force along the length direction of the clamping plate 3, and when the clamping plate 3 abuts against the fixing plate 2, the force causes the clamping plate 3 to press the fixing plate 2, thereby clamping the canvas clamped between the clamping plate 3 and the fixing plate 2. Further, when the clamping plate 3 abuts against the fixed plate 2, both the fixed plate 2 and the clamping cylinder 5 are perpendicular to the clamping plate 3. At the moment, a dead point structure is formed between the clamping cylinder 5, the clamping plate 3, the rotating shaft 4 and the fixing plate 2, the clamping plate 3 and the fixing plate 2 cannot be separated, and the clamping firmness of the canvas is guaranteed.
In the preferred embodiment of the present invention, the fixing plate 2 is vertically disposed, and the clamping plate 3 abuts against the lower end of the side surface of the fixing plate 2. The vertical setting of fixed plate 2 makes the entering that the turn-ups canvas that makes progress along the frame side can be accurate press from both sides between splint 3 and fixed plate 2 to guarantee that the canvas is by stable centre gripping. For preventing the canvas from slipping from between the clamping plate 3 and the fixed plate 2, in this embodiment, the 3 tip of clamping plate is provided with anti-skidding gasket, 2 surfaces of fixed plate are provided with anti-skidding stupefied. Further, in this embodiment, for facilitating the disassembly and assembly, the rotating shaft 4 is connected to the fixing plate 2, so that the clamping plate 3 can be detached together only by detaching the fixing plate 2 from the mounting plate 1, the fixing plate 2 can be perpendicular to the fixing plate 2 when the clamping plate 3 abuts against the fixing plate 2, the fixing plate 2 is arranged to have a broken line type cross section, the back of one end of the fixing plate 2 is fixedly connected to the mounting plate 1, the front of the other end of the fixing plate 2 is abutted to the clamping plate 3, and the rotating shaft 4 is connected to the bent portion of the fixing plate 2.
Because at the in-process that die clamping cylinder 5 released, the contained angle between grip block 3 and the die clamping cylinder 5 changes, for preventing that the card from dying to cause unable removal between the two, grip block 3 with die clamping cylinder 5 links to each other through first flake bearing 6. Further, in order to ensure the flexibility of rotation between the rotating shaft 4 and the fixing plate 2, the rotating shaft 4 is a second fisheye bearing 7.
Referring to fig. 3, a schematic view of an embodiment of a fabric clamping device of a frame stretching machine according to the present invention is shown. The utility model discloses an among the clamping device, the centre gripping subassembly is provided with a plurality ofly along mounting panel 1's length direction side by side. Thereby will firmly the centre gripping a side of canvas to tighten the canvas from both sides, guarantee to decorate the unanimity of drawing quality. In order to facilitate assembly and disassembly, in this embodiment, the mounting plate 1 of each of the clamping assemblies is of an integrated structure, and the fixing plate 2 of each of the clamping assemblies is also of an integrated structure. Effectively reducing the assembly steps.
