Description
Technical field
The present invention relates to a kind of weld jig of auto parts, particularly relate to the Anti-deformation mechanism on a kind of weld jig of dashboard cross member.
Background technology
Dashboard cross member is across in the driving cabin of automobile, it is a kind of important load carrier on automobile, main installation automobile instrument, electrical part, air bag and steering etc., when automobile collides, dashboard cross member plays booster action to whole driving cabin.Dashboard cross member is provided with alignment pin and some more thick and heavy sheet metal component supports.These supports are all adopt welding manner to be fixed on the pipe of dashboard cross member.Dashboard cross member pipe in welding process, because welding high arc temperature causes gross distortion.Comprise the distortion such as shortening, Angulation changes, flexural deformation serious, make the horizontal assembly size of dashboard cross member be difficult to ensure, affect car load assembling.Generally at present correct distortion by increasing reversible deformation weld seam, this kind of method not only increases complete vehicle weight, increases cost, and also unstable to the control of assembly size.
Summary of the invention
The object of the invention is to the defect overcoming prior art, Anti-deformation mechanism on a kind of weld jig of dashboard cross member is provided, it can, to the additional rigid restraint power contrary with welding direction of the pipe of fascia board girder, make fascia board girder effectively can eliminate welding deformation when welding.
The object of the present invention is achieved like this: the Anti-deformation mechanism on a kind of weld jig of dashboard cross member, the hold-down mechanism comprising the bracing frame on the base plate being arranged on described weld jig and be arranged on bracing frame, wherein,
Support frame as described above comprises a riser and forward and backward floor; Described riser be longitudinally arranged on the upper surface of described base plate middle part and with the upper surface α at angle of base plate; Described front floor is laterally arranged on the upper surface of described base plate and is vertically connected on the middle part of the front end face of described riser, the lateral surface of this front floor and the upper surface of base plate β at angle; Described rear floor is laterally arranged on the upper surface of described base plate and is vertically connected on a side of the rear end face of described riser, the top of the lateral surface of this rear floor and the upper surface of base plate θ at angle, the bottom of the lateral surface of this rear floor and the upper surface of described base plate at a right angle;
Described hold-down mechanism comprises a compression cylinder, a connecting rod and a pressure head; Described compression cylinder is arranged on the middle part of the rear end face of described riser in its piston rod mode upwards, one end of described connecting rod and the piston rod of compression cylinder hinged; Described pressure head is arranged on the top of described riser actively, the rear end of this pressure head and the other end of described connecting rod hinged.
Anti-deformation mechanism on the weld jig of above-mentioned dashboard cross member, wherein, described compression cylinder is arranged on the rear end face of described riser by a L-square.
Anti-deformation mechanism on the weld jig of dashboard cross member of the present invention, adopt increases a bracing frame and and is arranged on hold-down mechanism on bracing frame on the base plate of weld jig, be connected by angled between bracing frame with base plate, soldering angle during sheet metal component support on welding of automotive dashboard cross member of this angle and bonding machine is identical, can to the additional rigid restraint power contrary with welding direction of the pipe of fascia board girder, make fascia board girder effectively can eliminate welding deformation when welding, and reversible deformation weld seam can be cancelled, both can be cost-saving, the loss of weight object of dashboard cross member can also be reached.
Accompanying drawing explanation
