Summary of the invention
The problem to be solved in the present invention is to provide a kind of connecting rod joint welding frock.Adopt frock in this to weld connecting rod, can improve product quality and production efficiency, reduce production costs.
For addressing the above problem, take technical scheme:
Connecting rod joint welding of the present invention comprises base plate by frock, is characterized in that described base plate is horizontally disposed, above contiguous its one side, has gripper shoe, and the plate face of described gripper shoe is vertical with the upper surface of described base plate.There is the first locating piece coordinating with the locating snap ring on welded connecting rod gripper shoe inner side, the straight flange that has at least two correspondences and be parallel to each other on this first locating piece, the respective face of one of them straight flange and gripper shoe offsets, and has the gap coordinating with the locating snap ring on welded connecting rod on another straight flange.On described the first location is fast, be useful on the pressing plate of pushing down welded locating snap ring.There is location plush copper described pressing plate one end, has the vertical groove being communicated with described top on the medial surface of gripper shoe top, and welding is located plush copper described in during connecting rod and is moving type and embeds in described vertical groove.On the pressing plate corresponding with the welded locating snap ring center of circle and base plate, there are respectively axis hole and screw, in axis hole, have the first screw.During welding, described the first screw screws in the screw on described base plate behind the bar hole through axis hole, locating snap ring and welded base bar respective ends pressing plate successively from pressing plate top.
Wherein, described pressing plate is T font plate, the center in the transverse part outside of described location plush copper in T font plate.
Along the middle part of described gripper shoe, have at least two screw rods that are used for limiting the gusset bar position on welded connecting rod, described two screw rods all stretches out in welded connecting rod one side, and described external part is equal in length.
Between the described bolt being adjacent at described first locating piece, have lever, one end of described lever be fixed in described gripper shoe and make its in welded condition lower block the gusset bar one end at welded connecting rod.
It is fast that one end above of described base plate is fixed with the second location for connecting rod is longitudinally positioned.
Between two of welded connecting rod and described base plate, all there is cushion block.
The arranged outside of described gripper shoe is useful on the stiffener that withstands gripper shoe, and described stiffener is right angled triangle, and two straight flange is all connected with gripper shoe and base plate respectively mutually by screw.
Take such scheme, have the following advantages:
As can be seen from the above scheme, owing to being horizontally disposed at described base plate, above contiguous its one side, there is gripper shoe, there is the first locating piece coordinating with the locating snap ring on welded connecting rod gripper shoe inner side, the straight flange that has at least two correspondences and be parallel to each other on this first locating piece, the respective face of one of them straight flange and gripper shoe offsets, and has the gap coordinating with the locating snap ring on welded connecting rod on another straight flange.On described the first locating piece, be useful on the pressing plate of pushing down welded locating snap ring.There is location plush copper described pressing plate one end, on the medial surface of gripper shoe top, has the groove being communicated with described top, welding during connecting rod described in plush copper be moving type and embed in described groove.On the pressing plate corresponding with the welded locating snap ring center of circle and base plate, there are respectively axis hole and screw, in axis hole, have the first screw.During welding, described the first screw screws in the screw on described base plate behind the bar hole through axis hole, locating snap ring and welded base bar respective ends pressing plate successively from pressing plate top.No matter be to install or take out workpiece, as long as unload lower platen, do not need connecting rod just upwards to lift and can level shift out, not only time-consuming less, operating efficiency is high, and can guarantee that in finished product connecting rod that joint welding is good, the distance of locating snap ring and base bar bottom surface is controlled in the margin of tolerance, makes product quality better, do not need to do over again, thereby reduced production cost.
