Description
Technical field
The utility model relates to the welding tooling of sheet metal component, is specifically related to the upper pressing arm mechanism on welding tooling.
Background technology
On body of a motor car, need a large amount of sheet metal components, sheet metal component need to weld by welding tooling.Different due to sheet metal component self, welding tooling needs in conjunction with upper pressing arm mechanism and presses down arm mechanism to position sometimes, upper pressing arm mechanism compresses the top of sheet metal component by upper pressing arm and the template that is fixed on ground, presses down arm mechanism and by lower pressure arm and another template that is fixed on ground, the bottom of sheet metal component is compressed.
Upper pressing arm mechanism comprises upper pressing arm and is fixed on the template on ground, upper pressing arm is positioned at the top of template, one end and the template of upper pressing arm are hinged, the other end of upper pressing arm is provided with positioning convex, on described template, be provided with the detent mating with positioning convex, described upper pressing arm can rotate around pin joint, when in impaction state, the positioning convex of upper pressing arm stretches in the detent of template sheet metal component is compressed, after having welded, upper pressing arm turns to open mode around pin joint, adopts operation manually to realize and compresses and opening action.
The subject matter that said structure exists is: when upper pressing arm is when impaction state (in the welding process in sheet metal component), be easy to be misused and become open mode, need to again compress, both affected welding progress, reduced again welding precision; When upper pressing arm is during in open mode, be easy to again be misused and become impaction state, thereby operator's safety is constituted a threat to.
Utility model content
The utility model improves for above-mentioned technical problem, plan provides a kind of the welding of sheet metal parts frock upper pressing arm mechanism, neither can, because maloperation becomes upper pressing arm into open mode from impaction state, can upper pressing arm not become to impaction state from open mode because of maloperation yet.
For this reason, the technical scheme that the utility model adopts is: a kind of the welding of sheet metal parts frock upper pressing arm mechanism, comprise template (1) and upper pressing arm (2), described upper pressing arm (2) is positioned at the top of template (1), one end of upper pressing arm (2) and template (1) are hinged, the other end of upper pressing arm (2) is provided with positioning convex (2a), on described template (1), be provided with the detent (1a) mating with positioning convex (2a), key is: on the sidewall of described upper pressing arm mechanism, be provided with active grab (3), active grab (3) is selected GH-40840 series, the rotatable link of active grab (3) is partly arranged on template (1), hook portion is arranged on upper pressing arm (2), when upper pressing arm (2) compresses, active grab (3) is locked at compacted position by upper pressing arm (2), at the articulated position place with upper pressing arm (2) near template (1), be provided with locking pin (4), when upper pressing arm (2) is opened, described locking pin (4) passes template (1) and upper pressing arm (2), thereby upper pressing arm (2) is locked to open position.
On described template (1), near template (1), be provided with two blocks of upwardly extending flaps (5) with the articulated position place of upper pressing arm (2), the termination of described upper pressing arm (2) is stretched between two flaps (5), and by level pass the jointed shaft (6) of two flaps (5) and upper pressing arm (2) and be arranged on flap (5) and jointed shaft (6) between ball bearing (7), realize the hinged of upper pressing arm (2) and template (1).Flap is set separately on template, for hinged with upper pressing arm, simplifies the structure, reduced manufacturing cost; Upper pressing arm and template are realized hinged by jointed shaft and ball bearing, make the precision of upper pressing arm in motion process higher.
Described positioning convex (2a) is that semicircle is spherical, and correspondingly, detent (1a) is semicircle spherical groove.The spherical realization of semicircle location, the whole smooth surface that is of positioning convex and detent, can not damage sheet metal component during clamping.
The beneficial effects of the utility model: no matter be at impaction state, or open mode, upper pressing arm mechanism is provided with corresponding locking mechanism, prevents from being misused, safe and reliable, and has guaranteed welding precision and the welding efficiency of sheet metal component.
