DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 5

[0026] A material clamping device includes a fixed plate 1 and a lifting mechanism 2 and a moving mechanism 3 arranged on the fixed plate 1, wherein the moving mechanism 3 includes a first driving part 31 and a second driving part 32 which are symmetrically arranged and move toward / away from each other. It is worth noting that in this embodiment, the moving mechanism 3 can be in a variety of forms, specifically a bidirectional cylinder, and of course two cylinders or two electric push rods can also be used, and the functions of the utility model can also be realized by using two cylinders as the first driving part 31 and the second driving part 32 respectively.

[0027] For the convenience of description, the movement direction of the first driving unit 31 / the second driving unit 32 is defined as the X-axis, the direction perpendicular to the X-axis and located in the horizontal direction is defined as the Y-axis, and the direction perpendicular to the X-axis and located in the vertical direction is defined as the Z-axis.

[0028] The ends of the first driving part 31 and the second driving part 32 are both provided with a movable plate 33 and a movable clamp 34 for clamping the rib 9, and the movable clamp 34 is connected to the movable plate 33. The movable clamp 34 includes a first fixed end 341, a first free end 342 and a first connecting end 343 connecting the two, and a first avoidance space 344 for placing the end of the rib 9 is formed between the first free end 342 and the first connecting end 343, and the two first avoidance spaces 344 are arranged opposite to each other and limit the X-axis movement of the rib 9.

[0029] The lifting mechanism 2 includes a guide post 21 movably inserted in the fixing plate 1. The fixing plate 1 is provided with a through hole (not shown in the figure) for the guide post 21 to be inserted. The guide post 21 is arranged on one end above the fixing plate 1 and fixed with a limit nut 22. The guide post 21 is arranged on one end below the fixing plate 1 and fixedly connected with a pressing plate 23. The outer wall of the guide post 21 between the fixing plate 1 and the pressing plate 23 is also sleeved with a spring 24. The lower surface of the pressing plate 23 is parallel to the upper surface of the first free end 342. A second escape space 25 is formed between the lower surface of the pressing plate 23 and the upper surfaces of the two first free ends 342 for placing the umbrella rib 9 and limiting the Z-axis movement of the umbrella rib 9. When the umbrella rib 9 is placed in the second escape space 25, the spring 24 presses the pressing plate 23 downward so that the pressing plate 23 can be pressed against the umbrella rib 9. At the same time, the limit nut 22 prevents the pressing plate 23 from being separated from the fixing plate 1 due to its own gravity. The guide post 21 can move between the limit nut 22 and the pressing plate 23.

[0030] The lower surface of the pressing plate 23 is provided with a plurality of strip grooves 231 along the Y-axis direction for the ribs 9 to pass through and to limit the Y-axis movement of the ribs 9. Preferably, one strip groove 231 is a group, and a plurality of groups of strip grooves 231 are arranged in sequence and equidistantly on the lower surface of the pressing plate 23, so that a single strip groove 231 can clamp a single rib 9; or a plurality of strip grooves 231 are a group, and a plurality of groups of strip grooves 231 are arranged in sequence and equidistantly on the lower surface of the pressing plate 23, so that a plurality of strip grooves 231 can clamp a plurality of ribs 9.

[0031] In this embodiment, the two first connecting ends 343 can limit the X-axis movement of the umbrella rib 9, the plurality of strip grooves 231 can limit the Y-axis movement of the umbrella rib 9, and the pressure plate 23 and the two first free ends 342 can limit the Z-axis movement of the umbrella rib 9. Compared with manual material arrangement, the work efficiency can be improved, and the utility model has the advantages of simple structure and stable operation. The utility model can clamp multiple umbrella ribs 9 at a time, and can stably clamp the umbrella ribs 9 with inconsistent straightness or inconsistent cross-sectional dimensions due to processing errors.

[0032] Furthermore, the two first fixed ends 341 are connected to the corresponding movable plate 33 through the first bolts 41, and the movable plate 33 is provided with a first waist-shaped groove 331 at the position corresponding to the first bolts 41, and each first bolt 41 is movably arranged in the corresponding first waist-shaped groove 331. The movable jaw 34 is moved along the X-axis by the first driving part 31 / the second driving part 32 to achieve a first expansion / retraction, and can also achieve a second fine adjustment by moving the first bolt 41 in the first waist-shaped groove 331.

[0033] Furthermore, the present embodiment also provides another structure, which is two fixed jaws 35. The fixed jaws 35 include a second fixed end 351 and a second free end 352 connected to each other. The two second fixed ends 351 are respectively connected to the fixing plate 1 through the second bolts 42. The second free end 352 is abutted against the first free end 342 at one end away from the second fixed end 351. The fixing plate 1 is provided with a second waist-shaped groove 11 at a position corresponding to the second bolt 42. Each second bolt 42 is movably arranged in the corresponding second waist-shaped groove 11. Specifically, the angle between the second fixed end 351 and the second free end 352 is an obtuse angle. By setting the fixed jaws 35 with an obtuse angle, not only the X-axis movement of the umbrella rib 9 can be limited, but also the umbrella rib 9 can be pressed, thereby further limiting the Z-axis movement of the umbrella rib 9.

[0034] By adopting the above-mentioned design scheme, the beneficial effect of the utility model is: through the relative movement of the first material slot on the first material plate and the second material slot on the second material plate, the rod is deformed to generate tension, and the mechanical clamping of the rod is realized. Compared with manual material arrangement, the work efficiency can be improved. The utility model does not need to set up a complex elastic mechanism, and directly uses the deformation tension of the rod to clamp the rod, which has the advantages of simple structure and stable operation. The utility model can clamp multiple rods at a time, and the utility model can stably clamp the rods with inconsistent straightness or inconsistent cross-sectional dimensions caused by processing errors.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
