A kind of subframe weld jig
Technical field
The utility model belongs to welding technology field, relates to a kind of subframe weld jig, relates in particular to a kind of subframe stud welding anchor clamps of multidirectional layout welding screw; Be specially adapted to the transposition processing of subframe double-screw bolt manual welding.
Background technology
Multidirectional layout welding screw subframe adopts the robot welding cost very high, and existing multidirectional layout welding screw subframe manual welding cost is low, but anchor clamps are heavy, the operation inconvenient, the anchor clamps cost is high.
Summary of the invention
The utility model discloses a kind of subframe weld jig, and multidirectional layout welding screw subframe adopts the robot welding cost high in the prior art to solve; Problems such as the manual welding anchor clamps are heavy, operation inconvenience, anchor clamps cost height.
The utility model technical solution is following: comprise positioner, hold down gag; It is characterized in that: also comprise turning device, move running gear; Mobile running gear comprises movable pedestal, column, and column is installed on the movable pedestal; Has dead eye on the column; Comprise swing bolster and main support, rotating shaft, rotating disc, balancing weight on the turning device; Swivel bearing on the column of rotating shaft and mobile running gear is slidingly matched; Rotating disc and swing bolster and main the support are fastenedly connected through rotating shaft; Balancing weight is installed on the rotating disc; When rotating disc rotated, driven rotary axle, swing bolster and main the support with balancing weight were circumferentially rotated simultaneously; Positioner, hold down gag are fixed on the swing bolster and main support of turning device; Move the running gear horizontal level and move, make the utility model displacement conveniently access the preorder workpiece; The preorder workpiece places on swing bolster and main the support; Positioner is with workpiece location on swing bolster and main the support; Hold down gag supports Work-sheet pressing at swing bolster and master; The transposition of turning device upset workpiece, balancing weight and swing bolster and main support and workpiece upset equilbrium position are the welding operation position, the implementation welding.
The utility model also comprises the subframe gatherer; The subframe gatherer is installed on swing bolster and main the support; The alignment pin that the subframe gatherer is convenient to positioner inserts locating hole.
The utility model moves base plate, castor and the universal wheel that the movable pedestal of running gear comprises; Castor and universal wheel are installed in the base plate lower surface, realize that through Moving caster and universal wheel the utility model horizontal level moves.
The course of work is following:
The subframe of on general frock, accomplishing general stud welding is moved on on the utility model; The RPS1 point hole of workpiece is put into the utility model alignment pin and is located; Hold down gag compresses, and through the rotating disc counter clockwise direction rotary tooling of side, balancing weight makes frock turn to the equilbrium position; With stud welding gun splash the cover put into the double-screw bolt positioner, begin the welding operation of long welding screw.After welding is accomplished, manually rotate counterclockwise rotating disc, after swing bolster and main being supported be horizontal, unclamp hold down gag, take off workpiece, prepare to carry out the welding of next workpiece.
The utility model good effect is: easy and simple to handle, productive temp is fast; Cost is low; Guarantee the stud welding dimensional requirement, constant product quality.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 hold down gag, 2 stud welding positioners, 3 rotating discs, 4 lower part positioning devices, 5 balancing weights, 6 swing bolsters and main support, 7 subframe gatherers, 8 movable pedestals, 9 RPS1 location devices, 10 columns, 11 swivel bearings.
The specific embodiment:
Specify an embodiment of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1: the utility model comprises hold down gag 1, positioner, turning device, moves running gear, subframe gatherer 7; Positioner comprises stud welding positioner 2, lower part positioning device 4, RPS1 location device 9, and RPS1 location device 9 is an alignment pin; Turning device comprises rotating disc 3, balancing weight 5, swing bolster and main support 6, swivel bearing 11; Mobile running gear comprises movable pedestal 8, column 10, and the lower surface of movable pedestal has castor and universal wheel, and frock is done rectilinear motion through Moving caster and universal wheel.
Column 10 is installed on the movable pedestal 8; Swing bolster and main supports 6 and is installed on the column 10 through what swivel bearing 11 can circumferentially rotate; Rotating disc 3 is fastenedly connected with swivel bearing 11, and balancing weight 5 is installed on the rotating disc 3.Stud welding positioner 2, lower part positioning device 4, RPS1 location device 9, subframe gatherer 7 are installed in swing bolster and main the support on 6.
The subframe of on general frock, accomplishing stud welding is moved on on the utility model, and the workpiece subframe places swing bolster and main the support on 6, and the subframe gatherer is convenient to alignment pin and is inserted locating hole; The RPS1 point hole of workpiece subframe is put into RPS1 location device 9 alignment pins and is located; Hold down gag 1 is pressed on swing bolster and main the support on 6 with the workpiece subframe; Rotating disc 3 through the side counterclockwise rotates turning device, and balancing weight 5 makes turning device turn to the equilbrium position; The stud welding gun cover that splashes is put into stud welding positioner 2, the beginning welding operation.After welding is accomplished, manually rotate counterclockwise rotating disc 3, make swing bolster and main support 6 be horizontal after, unclamp hold down gag, take off the workpiece subframe, prepare to carry out the welding of next workpiece subframe.
