Description

Turnover fixture anti-dropping apparatus
Technical field
The utility model relates to welding tooling manufacturing technology field, especially a kind of anti-dropping apparatus for welding turnover fixture.
Background technology
As the metal sheet tow sides of body in white plate class all will carry out titanium dioxide protection weldering in automobile making, need the welding realizing body in white plate two sides with the turnover fixture be welded during welding, the compressing unit usually in these turnover fixtures is all clamped by air cylinder driven and realizes upset; There is a kind of turnover fixture of welding, this turnover fixture comprises the multiple compressing units by air cylinder driven be located on rollover stand, each described compressing unit comprises the holder of clamping part under being provided be fixed on described rollover stand and is hinged on the live splint on this holder by hinge, described live splint is provided with the upper clamping part corresponding with described lower clamping part and the connecting portion hinged with the piston rod of described cylinder, and described hinge is on described between clamping part and described connecting portion.In use there are the following problems for this turnover fixture: 1, because the pin joint of holder and live splint is between the two ends of live splint, and when dying appears in air supply system or air pressure reduces, the power on piston rod is zero; Now live splint can rotate freely around hinge, and raw metal sheet can drop phenomenon under Gravitative Loads, can smash workpiece, damage equipment, even hurt the production accident of operator time serious.
Utility model content
The problem that the utility model solves is to provide a kind of turnover fixture anti-dropping apparatus, the problem easily dropped with metal sheet in the turnover fixture use procedure solving existing welding.
In order to solve the problem, the technical solution adopted in the utility model is: this turnover fixture anti-dropping apparatus includes cylinder, is fixed on the holder of clamping part under being provided with on rollover stand and is hinged on the live splint on described holder by hinge; Described live splint is provided with the upper clamping part corresponding with described lower clamping part and is provided with the connecting portion of the first swivel pin, described hinge is on described between clamping part and described first swivel pin, described connecting portion is hinged with connecting plate by described first swivel pin, described connecting plate is hinged with rocker by the second hinge, described rocker passes through the 3rd hinge on described holder, described rocker is provided with four hinge hinged with the piston rod of described cylinder, and described 4th hinge is positioned at described first swivel pin rear; Described holder is movably equipped with the dogbolt abutted against with described rocker.
In above-mentioned turnover fixture anti-dropping apparatus technical scheme, technical scheme can also be more specifically: described 3rd bearing pin is fixed on described holder by mount pad.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect: due to hinged between live splint and the piston rod of cylinder connecting plate and rocker, when cylinder is died suddenly, be contained in the deadweight of metal sheet between the lower clamping part of holder and the upper clamping part of live splint to upper, lower clamping place i.e. clamping point one power upwards, now, upper clamping part has the trend turned clockwise around hinge, connecting plate and rocker have the trend turned clockwise around the second hinge, but due to the trend that dogbolt prevents rocker to turn clockwise around the second hinge, thus the lower clamping part of holder and the upper clamping part of live splint cannot be opened, still metal sheet is clamped, prevent dropping of metal sheet, serve proterctive equipment, workpiece, the effect of protection operator safety.

Detailed description of the invention
Below in conjunction with attached Example, the utility model is described in further detail:
Be illustrated in figure 1 a kind of turnover fixture of welding, this turnover fixture comprises the multiple compressing units driven by cylinder 2 be contained on rollover stand 1, and each compressing unit comprises and is installed on the holder 4 on rollover stand 1 by mount pad 3 and is hinged on the live splint 5 on this holder 4 by hinge 6.
Turnover fixture anti-dropping apparatus shown in Fig. 2, Fig. 3 and Fig. 4 includes the cylinder 2 be contained on rollover stand 1, be fixed on the holder 4 of clamping part 4-1 under being provided with on rollover stand 1, holder 4 is hinged with live splint 5, live splint 5 is fixedly connected with support 6-1, and support 6-1 is hinged on holder 4 by hinge 6; Live splint 5 is provided with the upper clamping part 5-1 corresponding with the lower clamping part 4-1 of holder 4 and connecting portion 5-2, and connecting portion 5-2 is equipped with the first swivel pin 7-1; Hinge 6 is between the upper clamping part 5-1 and the first swivel pin 7-1 of upper live splint 5; The connecting portion 5-2 of live splint 5 is hinged with connecting plate 7 by the first swivel pin 7-1, and connecting plate 7 is hinged with rocker 8 by the second hinge 7-2, and rocker 8 is hinged on mount pad 10 by the 3rd bearing pin 8-1, and mount pad 10 is fixed on holder 4 by rivet; Rocker 8 has pin-and-hole, rocker 8 by be installed on the 4th hinge 2-2 on this pin-and-hole and piston rod 2-1 and cylinder 2 hinged; 4th hinge 2-2 is positioned at the rear of the first swivel pin 7-1; Holder 4 has screwed hole, at this screwed hole, dogbolt 7 is housed; Movable adjustment dogbolt 7 during installation, makes the side of the top of dogbolt 7 and rocker 8 abut against, and dogbolt 7 abuts place between the second hinge 7-2 and the 3rd bearing pin 8-1 with rocker 8 side.
When cylinder 2 is died suddenly, be contained in the deadweight of metal sheet between the lower clamping part 4-1 of the holder 4 and upper clamping part 5-1 of live splint 5 to upper and lower clamping place i.e. clamping point one power upwards, now, upper clamping part 4-1 has the trend turned clockwise around hinge 6, connecting plate 7 and rocker 8 have the trend turned clockwise around the second hinge 7-2, but due to the trend that dogbolt 7 prevents rocker 8 to turn clockwise around the second hinge 7-2, thus the lower clamping part 4-1 of the holder 4 and upper clamping part 5-1 of live splint 5 cannot be opened, still metal sheet is clamped; Prevent dropping of metal sheet, serve proterctive equipment, workpiece, the effect of protection operator safety.
