Label in figure is expressed as: 1, threaded connection hole; 2, upper holder block; 3, workpiece locating slot; 4, lower support piece; 5, locating groove; 6, spring plenum length; 7, trapezoidal contiguous block; 8, through hole; 9, baffle ring; 10, locating dowel; 11, spacing straight-bar; 12, spring; 13, straight-bar pilot hole.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
The double fixed-position welding device of a kind of welded nut as shown in Figure 1, comprises upper holder block 2 and the lower support piece 4 of relatively upper and lower setting, and described upper holder block 2 upper ends are provided with joint pin, are provided with threaded connection hole 1 in joint pin; Described lower support piece 4 is provided with two vertical helical spring cavitys 6, is provided with spring 12 in spring plenum length 6, and spring 12 upper ends are connected with locating dowel 10, and locating dowel 10 middle parts are provided with baffle ring 9, and described lower support piece 4 lower surfaces are provided with trapezoidal contiguous block 7.
The present embodiment upper holder block 2 is threaded connection hole 1 and is connected to welding machine upper end, lower support piece 4 is connected on the workbench of welding machine by trapezoidal contiguous block 7, during use, upper holder block 2 is over against lower support piece 4, welded nut is placed on to baffle ring 9 upper ends, and welded nut mesopore is enclosed within locating dowel 10 tops, workpiece correspondence is placed on to lower support piece 4 and welded nut top, upper holder block 2 is descending exerts pressure, spring compresses descending under pressure 12, now locating dowel 10 moves to spring plenum length 6, nut is thereupon descending, when pressure is enough, upper holder block 2 stops descending, welded nut compresses under the effect of spring 12 and upper holder block 2, now welded nut upper end weld is positioned at lower support piece 4 upper ends, can weld, in the present embodiment, nut is due to the effect of back-up ring 9 and locating dowel 10 when compressing, and its upper surface can fit tightly with workpiece all the time, and binding face is stressed evenly, welded nut welding position dimensional accuracy is high, and convenient welding is taken out workpiece after welding, spring reset is got back to home position, can reuse, simple in structure, easy to use, without artificial adjustment, reduced welding error, and improved welding efficiency and welding effect, practicality greatly improves.
In the present embodiment, two welded nuts that have centre-to-centre spacing to require are positioned and clamp welding simultaneously, can guarantee the centre-to-centre spacing of two welded nuts, centre-to-centre spacing error can be controlled at ± 0.25 between, thereby greatly improved welding position precision, two welded nuts compress simultaneously and weld also and saved weld interval, have improved welding efficiency.
The present embodiment has increased following structure on the basis of embodiment 1: described locating dowel lower end is provided with spacing straight-bar 11, described lower support piece 4 is positioned at spring plenum length 6 center bottom and is provided with straight-bar pilot hole 13, and described spacing straight-bar 11 lower ends are positioned at straight-bar pilot hole 13.
Spacing straight-bar 11 in the present embodiment not only can guarantee that locating dowel 10 can keep vertical when moving down; guarantee the welding position of nut; and can also play good guide effect to moving up and down of locating dowel 10; avoid baffle ring 9 to block; also can protect spring 12 simultaneously; avoid the excessive pressurized of spring 12 and damage, having extended 12 service lifes of spring.
The present embodiment has been optimized baffle ring on the basis of embodiment 1 or embodiment 2, is specially: on described baffle ring 9, be provided with through hole 8, through hole 8 is in communication with the outside the spring plenum length 6 of baffle ring 9 lower ends.
