It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention will be further described with reference to the following examples.

Examples

The clamp holder for clamping the automobile curved surface part is disclosed in the embodiment, and referring to fig. 1-3: including the mounting panel 2 of "L" shape, the connecting cylinder 4 that the interval set up about the top end of mounting panel 2 all is fixed with, common coaxial clearance normal running fit has dwang 5 in the connecting cylinder 4, is equipped with fastener 6 between the one end of dwang 5 and the connecting cylinder 4, and the middle section of dwang 5 is connected with fixture 7 that the longitudinal symmetry set up. The mounting plate 2 and the components mounted thereon together form a set of grippers; when in use, a plurality of sets of clamps are required to be matched to assemble the clamp, and the bottom end of each mounting plate 2 is connected to a substrate.

The clamping mechanism 7 comprises a connecting arm 8 fixedly connected (for example welded) with the rotating rod 5, the tail end of the connecting arm 8 is provided with three through holes 9 distributed in a circular array, a T-shaped pressure rod 10 used for clamping a curved surface accessory is arranged in each through hole 9 in a clearance fit mode, a sleeve 11 sleeved outside each T-shaped pressure rod 10 is fixedly arranged on the top surface of each through hole 9, the connecting arm 8 is provided with an air cylinder 12 in the center of each through hole 9, the top of each air cylinder 12 is spirally connected with an adjusting bolt 13, the inner end of each adjusting bolt 13 is rotatably connected with a piston 14, the bottom of each air cylinder 12 is communicated with the corresponding sleeve 11 through a circular tube 16, and a piston rod 17 used for abutting against the T-shaped pressure.

The fastening device 6 includes a disk 601 fixedly connected to one end of the rotating rod, a locking bolt 602 is screwed onto the edge of the disk 601, the inner end of the locking bolt 602 abuts against the connecting cylinder 4, and a rotating knob 15 is fixedly connected to the other end of the rotating rod 5.

The T-shaped pressing rod 10 and the sleeve 11 are provided with matched vertical planes, the vertical planes are aligned to the round pipe 16, and a rectangular guide block and a rectangular guide groove which are matched are arranged between the T-shaped pressing rod 10 and the sleeve 11.

The working principle is as follows: the angle of the connecting arm 8 is adjusted according to the edge curvature and radian of the curved sheet-shaped spare and accessory parts, and the angle of the rotating rod 5 (two ends of the rotating rod 5 are provided with limiting rings so that the rotating rod 5 cannot move transversely) is adjusted by rotating the knob 15; after the angle is adjusted, the locking bolt 602 of the fastening device 6 is rotated to enable the inner end of the locking bolt to be close to the connecting cylinder 4, so that the friction force between the whole rotating rod 5 and the connecting cylinder 4 is increased, and the angle is further fixed; after the angle is adjusted, firstly, two sides of the curved sheet-shaped spare part are placed on a T-shaped pressure rod 10 of a clamping mechanism 7 below (the top end of the T-shaped pressure rod 10 below is provided with a limiting block, so that the curved sheet-shaped spare part cannot fall off from a through hole 9), then three T-shaped pressure rods 10 are pushed upwards according to the curvature and radian of a clamping point of the curved sheet-shaped spare part (the three T-shaped pressure rods 10 have better stability), so that the T-shaped pressure rods 10 protrude upwards by different lengths, meanwhile, the top ends of the T-shaped pressure rods abut against the lower surface of the curved sheet-shaped spare part, then an adjusting bolt 13 is rotated along the top of an air cylinder 12, so that the adjusting bolt 13 drives a piston 14 which is rotationally connected with the adjusting bolt 13 to move inwards to compress air, and because the volumes of the air cylinder 12 and a circular tube 16 are reduced, at the time, the air can, thereby realizing the position fixation of the T-shaped pressure lever 10; after the lower clamping mechanism 7 is fixed, the upper clamping mechanism 7 clamps the upper surface of the curved sheet part in the same way, and at the moment, the difference is that the T-shaped pressure lever 10 naturally falls onto the upper surface of the curved sheet part due to gravity, and the curved sheet part is effectively clamped through the operation steps; and the cooperation of a plurality of clampers arranged on the same substrate can realize the effective fixation of the curved surface sheet body parts.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
