Detailed description of the invention
Referring to Fig. 1 and Fig. 2, is the stereogram of a preferred embodiments welding equipment 10 and the exploded view of hold down gag 100.Welding equipment 10 comprises base plate 11, is located at the track 12 on base plate 11, support member 13 and the locating piece 14 for positioning supporting part 13.The shape of base plate 11 and big or small adaptive welding work pieces 200 sizes.
Hold down gag 100 is fixed on the track 12 on base plate 11.Hold down gag 100 comprises support 101, rotates the pressing plate 102 being fixed on support 101, the actuating unit 103 that promotion pressing plate 102 rotates and the supporting mechanism 104 of supporting welding workpiece 200.Separately, hold down gag 100 also comprises the tumbler 105 that support 101 and pressing plate 102 are rotationally connected and the elastic component 106 that pressing plate 102 is resetted.
Please refer to 3, support 101 comprises base 110, latch 111, steady pin 131, and with base 110 two support plate 141, two support plates 141 connected vertically between be connected with cross bar 135, cross bar 135 is parallel with base 110.Support 101 also comprises baffle plate 136, baffle plate 136 and vertical connect two stands 101 parallel with base 110.Support 101 is positioned on base plate 11 by steady pin 131.
On two support plates 141, be respectively equipped with two second through holes 142 and two first screws 143.Two first screws 143 are positioned at two second through hole 142 belows.Latch 111 is through two first screws 143 and sheathed elastic component 106 on it, and on latch 111, also sheathed two collar 112, two collars 112 lay respectively at elastic component 106 two ends and between two support plates 141, the two ends of latch 111 are screwed together in respectively in two first screws 143.Two collars 112 are held on elastic component 106 between two support plates 141.One end of elastic component 106 is supported and is terminated on cross bar 135, and the other end supports and terminates in pressing plate 102 lower surfaces.
Pressing plate 102 comprises the first round end 122, the second round ends 152 and the first perforation 162.The first perforation 162 of pressing plate 102 is between two second through holes 142 of two stands 101.Pressing plate 102 is between two support plates 141, and tumbler 105 is rotationally connected pressing plate 102 and support 101 through two second through holes 142 and the first perforation 162.Tumbler 105 one end are notch cuttype, and the other end is shaft-like.Tumbler 105 other ends are arranged with spacing collar 107, in case spline moving part 105 other ends depart from two second through holes 142.
Actuating unit 103 is fixed on support 101, comprises the force piece of power 113 is provided, lead 123, the spacer pin 153 that restricted guidance post 123 rotates and the fairlead 133 for sheathed lead 123 of contact force piece 113.Fairlead 133 vertical directions are provided with the first through hole 140.
Fairlead 133 comprises Part I 137 and Part II 138, and Part II 138 is stairstepping, and Part I 137 and Part II 138 also can be designed to an entirety.Part I 137 is arranged on baffle plate 136, and the first through hole 140 runs through Part I 137 and Part II 138.The height of Part I 137 and Part II 138 is all adjustable.Part II 138 is provided with horizontal pin-and-hole 148 near the vertical portion of its bottom surface, and pin-and-hole 148 sizes coordinate spacer pin 153.
Lead 123 can be in the interior slip of fairlead 133 through the first through hole 140, and one end of lead 123 can be plane or inclined-plane, and this end face supports the first round end 122 as for pressing plate 102.The other end of lead 123 supports the one end that terminates in force piece 113.The vertical direction of lead 123 is provided with stopper slot 130, and spacer pin 153 can slide up and down in stopper slot 130.In the time that lead 123 is subject to compressing of force piece 113, due to the effect of spacer pin 153, lead 123 can only move along stopper slot 130 directions, thereby has prevented that lead 123 from rotating.
