Description
Technical field
The present invention relates to a kind of weld jig, the especially a kind of weld jig second time of gear-box bracket of small automobile.
Background technology
Gear-box bracket of small automobile is used for gearbox and vehicle frame are installed; In welding process the product clamping stable be directly to have influence on dimensional accuracy of products and welding quality reliably; If assembling is unstable in welding process; The gap of weld will the time little when big, will cause that weld strength is unstable, the fusion penetration of welding is unstable, will cause scrapping of product.Simultaneously temperature can be very high in welding process, heat also can be very big, will cause the distortion of product to strengthen if the location is unstable, unreliable, makes the stable very poor of product, size be difficult to control.In welding process, also exist a large amount of splashing; All be welding slag on some important fitting surfaces of the product that makes; So also will spend lot of manpower and material resources and remove these and be melted in splashing of product surface, also influence the apparent of product, the surface quality of products that makes reduces greatly.After accomplishing, welding, product is taken out also very difficulty from anchor clamps owing to welding deformation.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide that a kind of welding process is easy to operate, quick, do not have the weld jig second time of welding slag gear-box bracket of small automobile on the fitting surface of product.
According to technical scheme provided by the invention; The weld jig second time of said gear-box bracket of small automobile; The left end and the right-hand member that are included in the upper surface of base plate are provided with a cover side core-pulling location inserted sheet symmetrically and add the cylinder alignment hold-down mechanism; Two cover side core-pullings location inserted sheets add piston rod in the cylinder alignment hold-down mechanism all to parallel the stretching out of upper surface front end of base plate; Left end and right-hand member at the upper surface of base plate are provided with a cover hinge type pneumatic clamping mechanism symmetrically, and the compressed part of the pressing plate in the two cover hinge type pneumatic clamping mechanisms is all near the center of base plate;
Said side core-pulling location inserted sheet adds the cylinder alignment hold-down mechanism and comprises the firm banking that fixedly installs; One end of firm banking is set with the cylinder holder; The other end of firm banking is set with the location inserted sheet; On the firm banking between cylinder holder and the location inserted sheet, be set with mount pad, on the cylinder holder, cylinder be installed, be connected with on the piston rod of cylinder and compress alignment pin; The said alignment pin that compresses has at the bottom of the alignment pin of compressing section and compresses the alignment pin leading portion; The diameter that compresses section at the bottom of the alignment pin is greater than the diameter that compresses the alignment pin leading portion, compress alignment pin at the bottom of section be slidingly connected in the mount pad, compress the alignment pin leading portion and be slidingly connected in the inserted sheet of location;
Said hinge type pneumatic clamping mechanism is included in the cylinder that base plate is installed; The piston rod end of cylinder is equipped with connector; Plate upper surface is fixed with mount pad, is hinged with connecting plate on the mount pad, and the middle part of pressing plate is hinged on the top ends of connecting plate; The tail end of pressing plate is hinged on the connector, and the compressed part of pressing plate is a tabular.
Be fixed with first support post at plate upper surface, on first support post, be provided with first alignment pin near a side guide.Be fixed with second support post at plate upper surface, near second support post, be provided with second alignment pin near the opposite side pressing plate.
Plate upper surface outside side core-pulling location inserted sheet adds the cylinder alignment hold-down mechanism is fixed with anchor clamps installing and locating pin.
The present invention because adopted cylinder, fast pressing plate is located, is compressed, so operation is very easy in welding process, quick.The present invention is owing to adopted square large-area pressing plates, so do not have welding slag on the fitting surface of product, the product that welds is without the place to go welding slag.Anchor clamps of the present invention can a clamping under the cooperation of welding robot and rotary table just with product welding completion.It can be fit to large batch of manufactured parts.
