Abstract
The utility model discloses a vehicle body positioning and clamping mechanism, which comprises a fixed seat connected with a welding jig, wherein an upward extending supporting plate is fixedly connected onto the fixed seat, and a swing rod and a leftward extending rocker are hinged onto the supporting plate; the right extending end of the swing rod and the outward extending end of the rocker are respectively connected with connecting arms, and clamping blocks are respectively connected onto the two connecting arms and are oppositely arranged; the leftward extending end of the swing rod is hinged with a cylinder, and the piston rod of the cylinder is hinged with the connecting arm at the left side; and a left positioning block which is arranged corresponding to the connecting arm at the left side is arranged at the left side of the supporting plate, and a lower positioning block which is arranged corresponding to the connecting arm at the right side is arranged at the lower part of the right side of the supporting plate. The vehicle body positioning and clamping mechanism provided by the utility model has the advantages that the body-in-white with a complex three-dimensional space curved surface can be positioned, the positioning is simple and the precision is high, the processing and assembly are simpler and more convenient, the design space and the occupied space of equipment are saved, and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of vehicle body positioning clamping mechanism.
Background technology
At present, the automobile body-in-white welding procedure mainly realizes at weldering tire fixture.Existing weldering tire fixture is when the location, because bodywork parts is the thin-walled plate mostly, piece surface is complicated three-dimensional space curved surface, in clamping process, needs to use multipoint positioning to clamp, when adopting a plurality of alignment pins to position, location structure is complicated and easily produce interference problem, and picks and places part inconvenience, and the clamping dynamics that adopts alignment pin to locate can cause welding quality to descend not, and can cause equipment, workshop and personnel's waste, production efficiency is low.
The utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly is exclusively used in that body of a motor car is complex-curved carries out pinpoint vehicle body positioning clamping mechanism.
For solving the problems of the technologies described above, vehicle body positioning clamping mechanism with following design feature is provided: it comprises the holder that can be connected with weld jig, be connected with the gripper shoe of stretching on holder, the rocking arm that is hinged with swing arm on gripper shoe and stretches out towards the left side, the right external part of swing arm and the overhanging end of rocking arm are connected with respectively linking arm, be connected with respectively fixture block on two linking arms, two fixture blocks are oppositely arranged, the left external part of swing arm is hinged with cylinder, and the piston rod of cylinder and the linking arm in left side are hinged.
The left positioner piece of position and the corresponding setting of linking arm in left side is equipped with in the left side of described gripper shoe, and the lower right side of gripper shoe is equipped with the bottom locating piece with the corresponding setting of linking arm on right side.
Described cylinder is hinged by contiguous block and swing arm, is bolted with spacing double-screw bolt on contiguous block.
After adopting said structure, rotate by driving air cylinder driven rocking arm and swing arm, thereby make two fixture blocks clamp vehicle body, fixture block difform according to the vehicle body design of different three-dimensional space curved surfaces, thereby the purpose that realization clamps; And the setting of rocking arm and swing arm is scissor-shaped, thereby only needs fixture block that a cylinder just can realize both sides simultaneously in opposite directions or motion dorsad, clamps effective and precision is high, thereby realization is to the accurate location of automobile body-in-white.
In sum, the utility model is simple in structure, can carry out the location of the body in white of complex three-dimensional space curved surface, the location is simple and precision is high, and processing and assembling be fairly simple convenience all, has saved taking up room of design space and equipment, has greatly improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the schematic perspective view of a kind of embodiment of the utility model.
The specific embodiment
Vehicle body positioning clamping mechanism as shown in Figure 1, comprise the holder 1 that can be connected with weld jig, be connected with the gripper shoe 2 of stretching on holder 1, the Rocker arm 4 that is hinged with swing arm 5 on gripper shoe 2 and stretches out towards the left side; the right part of rocking arm is hinged on gripper shoe 2 by hinge; the approximate mid-section of swing arm is cut with scissors by hinge and is contained on gripper shoe 2 has adopted above-mentioned two hinges in figure, also can adopt a hinge to realize above-mentioned hinged.The right external part of swing arm 5 and the overhanging end of Rocker arm 4 are connected with respectively linking arm 6, being connected between linking arm 6 and swing arm and Rocker arm 4 adopts bearing pin hinged, be connected with respectively fixture block 3 on two linking arms 6, two fixture blocks 3 are oppositely arranged, require to design difform fixture block 3 according to different vehicle bodies, the left external part of swing arm 5 is hinged with cylinder 7, and the piston rod of cylinder 7 and the linking arm in left side 6 are hinged.
In order to realize accurate clamping and positioning, as shown in FIG., the left positioner piece 8 of position and the corresponding setting of linking arm 6 in left side is equipped with in the left side of gripper shoe 2, the lower right side of gripper shoe 2 is equipped with the bottom locating piece 9 with the corresponding setting of linking arm 6 on right side, bottom locating piece 9 can adopt the bolt that is screwed onto on gripper shoe 2, thereby can adjust its height; Cylinder 7 is hinged by contiguous block 10 and swing arm 5, is bolted with spacing double-screw bolt 11 on contiguous block 10.When the piston rod of cylinder stretches out when reaching predetermined stroke, the linking arm 6 in left side leans on left positioner piece 8, and spacing double-screw bolt 11 leans in the bottom of gripper shoe 2, and two fixture blocks 3 are realized the clamping of body in white mutually near to minimum of a value; When the piston rod of cylinder was retracted to predetermined stroke, linking arm 6 bottoms and the bottom locating piece 9 on right side offseted, and two fixture blocks 3 are mutually away to maximum, thereby unclamped the body in white of clamping.
