Background technology
Body of a motor car part is mostly thin-walled plate, its rigidity is very poor, piece surface (particularly car) is complicated three-dimensional space curved surface, the special soldering cramping apparatus that multipoint positioning clamps must be used in the process of being welded, and position in the process of clamping at the surfaces externally and internally of part, if the discontinuity equalization of surfaces externally and internally, part is easily caused to diminish, have a strong impact on body quality, in addition, under the three-dimensional space curved surface of above-mentioned part, need the position of clamping and positioning more, thus the problem that mainly should the solve when interference problem of soldering cramping apparatus becomes jig Design.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, provides that a kind of structure is simple, wagon sheet both sides stress equalization and the two positioning and clamping mechanism of the accurate single cylinder of clamping and positioning.
In order to solve the problems of the technologies described above, the two positioning and clamping mechanism of the single cylinder provided comprises bracing frame, its design feature is: the support frame as described above left and right sides is hinged with corresponding two connecting rods arranged, the overhanging end of two connecting rods is connected with clamp arm respectively, be hinged with compression cylinder between the lower end of two clamp arms, upper end correspondence is connected with clamping head, the left and right sides of bracing frame is equipped with and is positioned at above connecting rod and symmetrically arranged fixed stop, and the inner side of two clamp arms is equipped with the positive stop that arrange corresponding to fixed stop respectively.
Bracing frame is connected with down and stretches and limit the positioning baffle of compression cylinder piston rod retraction distance.
Clamp arm is provided with vertical spaced multiple bolt hole, and clamping head is connected on clamp arm by the bolt being installed on wherein part bolt hole.
The rear portion of described compression cylinder is fixed with end seat, the piston rod of compression cylinder is bolted with hinged ear seat, end seat is fixed with hinged seat, and wherein the lower end of a clamp arm is contained on hinged ear seat by hinge hinge, the lower end of another root clamp arm is contained on hinged seat by hinge hinge.
After adopting said structure, the utility model is applied to the location clamping of vehicle body soldering, shrink driving by the piston rod of compression cylinder and make two clamp arms, connecting rod rotates around the hinge dress position of connecting rod respectively, thus make the distance between two corresponding clamping heads become large, namely two clamping heads are driven to dehisce, when mechanism arrives position location, stretched out by the piston rod of compression cylinder, the action simultaneously of two corresponding clamping heads is drawn close mutually, thus the position of vehicle body location to be clamped is clamped, the setting of above-mentioned fixed stop and positive stop can make to put in place when being clamped to a certain degree stopping, make the range ability of two clamping heads identical, thus ensure that vehicle body surfaces externally and internally is stressed identical, the vehicle body adopting light sheet to make is avoided to sustain damage, and the surfaces externally and internally location clamping to wagon sheet can be realized by an above-mentioned cylinder, effectively prevent the interference problem because multiple positioning and clamping mechanism occurs, thus ensure that vehicle body soldering quality.
In sum, the utility model have that structure is simple, wagon sheet both sides stress equalization and the accurate advantage of clamping and positioning.
