Description
Technical field
The utility model belongs to automobile manufacture production field more particularly to a kind of turntable.
Background technique
To be welded be the key component of automobile manufacture for automobile integration, it be by stamping forming bodywork parts on fixture
After positioning steps up, the process of white body is assembled by electric welding, projection welding, CO2 protection weldering, soldering and viscous adhering process.
Since automobile manufacture industry enters semiautomatic-mode from craft, major automobile vendor is constantly modified production line
And optimization, last century Toyota Motor develop the automobile that first flexible production line can make a production line be suitable for multiple kinds
Then there is automated manufacturing mode and mixing manufacturing mode etc. in production, and in the welding process, each weldment is placed
Position not cannot be guaranteed it is consistent, even if for the weldment that same a batch will be welded, can not ensure each all
It is placed on the same position
The position of the difference of each weldment itself and each workpiece, tilt angle be also it is inconsistent, due to weldment position
This uncertainty, while to meet restriction freedom degree, use space rectangular axes are divided into 6 each freedom in technology
Degree, in order to guarantee the last welding precision of weldment and quality, it is necessary to the limitation of freedom degree is carried out to weldment.
Although the form of automobile welding and assembling clamp and machine tool fixture and theory are similar.But common fixture positioning
6 position principles, that is, the positioning of the plane and two pits passed through are generally used in design
Principle positions completely.However the Position Design of automobile welding and assembling clamp is carried out, common standard cannot be used,
Body of a motor car is space curved surface, the process of fixation and positioning and the same welding station of increase for automobile die.
Summary of the invention
The utility model designs a kind of turntable, including substrate fixed frame, connection frame, turntable, bottom regarding to the issue above
Plate, positioning mechanism;The substrate fixed frame further includes connecting rod, connects boss, connecting bottom board, fixed frame, connecting plate, described
Connecting rod one end is welded to connect boss, and on the welding substrate fixed frame of one end, the connecting bottom board is welded on substrate fixed frame
Bottom is bolted with bottom plate use, and the fixed frame is welded as a whole with substrate fixed frame, and the connecting plate is welded on solid
Determine on frame；
The substrate fixed frame is connect with connection frame screw rod, and the connection frame and turntable are connected using screw rod, and described turn
Platform and bottom plate are connected using screw rod, and the positioning mechanism is fixed on bottom plate.
It further, include bracket, fixed plate, connecting plate, gusset on connection frame, the bracket is square tubes soldering, described
Fixed plate is welded on connection frame top corner location, and the connecting plate is welded on four sides of connection frame, the link of boards
Turntable and connection frame, connection frame are symmetrically welded, and the influence because accelerating the inertia generated to running accuracy is reduced in rotary course.
Further, the positioning mechanism includes positioning pin, cylinder, support, and the positioning pin is fixed on the support, described
Cylinder is fixed on the support.
The utility model has the advantages that the utility model by substrate fixed frame, connection frame, bottom plate, positioning mechanism on-link mode (OLM) with
And positioning mechanism effectively increases positioning accuracy to the positioning of substrate fixed frame.
