Tool clamp for clamping irregular arc plate of automobile and method

Abstract

The invention belongs to the technical field of automobile arc plate machining and mounting and relates to a tool clamp for clamping an irregular arc plate of an automobile and a method. The tool clamp comprises a clamping base, a pressure-bearing air bag is arranged in a gap between a pair of clamping tables which are in bilateral symmetry, the lower end of the pressure-bearing air bag is communicated with a pair of buffering air bags which are in bilateral symmetry through a three-way pipe, the outer wall of the middle section of the pressure-bearing air bag is connected with an annular limiting ring in an extruding and clamping mode, the upper end of the pressure-bearing air bag is provided with a plurality of sets of pressing strips which are linearly distributed, the upper ends of the buffering air bags are provided with pressing plates which perform pressing downwards, and the upper ends of the pressing strips are connected with reinforcing strips with storage grooves in an inserted mode. According to the tool clamp, through the cooperation of a pulling rope and a hanging ring, the bottom of the pressure-bearing air bag is adjusted; and the pressing strips are used for supporting a workpiece, a machining position is limited through the insertion cooperation of the pressing strips and the reinforcing strips, so that the air bag is prevented from being affected by a cutter or machining chippings, and meanwhile unified recycling of the machining chippings is achieved.

Problems solved by technology

[0002] The mounting panels of automobiles are mostly curved and irregular panels. For the convenience and sealing of the installation and insertion, it is usually necessary to completely bend the side of the panel, and the angle of the bent panel is suitable for its installation position. , the bending angle is uncertain, which makes it difficult to achieve fixed clamping on the side of the arc plate during processing

[0003] At the same time, the bending angle of the arc plate needs to be supported during the processing to prevent the deformation of the bending angle during the drilling, cutting and other extrusion processes, which will affect the installation accuracy of the plate. However, because the outer wall of the lower end of the arc plate is not flat, The support is difficult, and it is easy to cause contact between the support and the tool during the machining process, which will cause damage to the support and affect the machining accuracy

[0004] To this end, a tooling fixture and method for clamping irregular arc plates of automobiles are provided to solve the problems of clamping, installation and processing support of arc-shaped plates
