This mechanism can solve the tight problem of the inside locating clip in narrow space.

Description

A kind of arrangements for automotive doors inner plate welding clamps mechanism

Technical field

The utility model relates to the weldprocedure frock field of arrangements for automotive doors welding production line, is specially a kind of pneumatic clamping mechanism being applicable in small space.

Background technology

In automotive body welding production process, adopt Pneumatic welding clamp more, ensure that fixture is to the accurate location of workpiece and effectively clamping with this. Pneumatic clamping conventional at present comprises cylinder, supports seat, locating surface and compression face etc., and locating surface is inboardend, is rotated centered by turning point by the tight face of cylinder push belt dynamic pressure, until contacting with locating surface, it is achieved clamping and positioning.

But, in actual applications, due to the reasons in structure of part itself, often require that fixture is in limited spatial dimension, reliable location (support and compress) should be realized, allow part fetching freely again. And fixture unit common at present can not realize this kind of function. Such as, between car door inner and outer plates to open grade dimension precision requirement higher, if there is quality problems, will directly affect glass lifting, it is easy to the problems such as roof leaking occur. So to be controlled by fixture in the welding process of car door, on inner plate of car door and outside plate, in stiffener welding process, (inner and outer plates is opened shelves and formed) needs all reliably to be located by two plates, this just relates to clamping (location and compression), and grade size of opening between interior plate and outside plate stiffener is only had an appointment 30mm, space is extremely narrow and small, existing clamping mechanism can not meet service requirements, this just requires a kind of clamping mechanism newly of design, its locating surface can not be stationary structure, reaches out the location inside shelves or compressing unit must be able to spin out.

Summary of the invention

The purpose of this utility model is to provide a kind of arrangements for automotive doors inner plate welding to clamp mechanism, to solve the problem that narrow space inside realizes location clamping.

Arrangements for automotive doors inner plate welding described in the utility model clamps mechanism, comprise cylinder, substrate, location component, pressed component, first swivel arm, 2nd swivel arm and lower link, the described bottom of the first swivel arm and the piston rod of cylinder and substrate are hinged, described pressed component is fixed on the top of the first swivel arm, the rear end of described 2nd swivel arm is hinged on the middle part of the first swivel arm, described location component is fixed on the front end of the 2nd swivel arm, when described first and second swivel arms turn to clamped condition by cylinder drive, Workpiece fixing is clamped by described pressed component and location component respectively by upper and lower both sides, the two ends of described lower link are hinged with the middle part of substrate and the 2nd swivel arm respectively, when described lower link turns to clamped condition, limiting section on itself and substrate is conflicted.

Preferably, the back up pad that described substrate comprises substrate body and is fixed in substrate body, described first swivel arm and lower link are hinged in described back up pad, and described substrate body side is fixed on base, and another side and cylinder barrel are hinged fixing.

Preferably, described lower link is provided with the limited block conflicted and coordinate with substrate limiting section.

The utility model has the advantage of: when not adopting multistage clamping or multiple fixture unit, promote location component and pressed component to rotate to prescribed position by single cylinder simultaneously, achieve with a clamping unit the narrow reliable location opening shelves of part, avoid the layout of more multiple clip unit, save cost, also provide bigger welding space simultaneously, increase technological feasibility and operation convenience.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.

Arrangements for automotive doors inner plate welding as shown in Figure 1 and Figure 2 clamps mechanism, comprises cylinder 1, substrate, the first swivel arm 4, the 2nd swivel arm 5 and lower link 6.

Described substrate is made up of substrate body 2 and the back up pad 3 being fixed in substrate body, and this substrate body side is fixed on base 7, and another side and cylinder barrel are hinged fixing.

The described bottom of the first swivel arm 4 and the piston rod of cylinder and back up pad 3 are hinged, are provided with pressed component 8 at the top of the first swivel arm.

The rear end of described 2nd swivel arm 5 is hinged on the middle part of the first swivel arm 4, is provided with location component 9 in the front end of the 2nd swivel arm.

The two ends of described lower link 6 are hinged with the middle part of back up pad 3 and the 2nd swivel arm 5 respectively, are provided with the limited block 11 that the limiting section 10 with substrate body 2 is conflicted and coordinated on the outer side of this lower link 6.

As shown in Figure 3, state is opened for above-mentioned clamping mechanism. When needs are to workpiece 12(inner plate of car door and outside plate stiffener) when positioning clamping, described cylinder operation piston rod outwards stretches out, and drive the first swivel arm 4 to rotate around the pin joint A of itself and back up pad, produce the component in f1 direction. Meanwhile, lower link 6 rotates around the pin joint B of itself and back up pad, produces the component in f2 direction. By the multi link running gear principle formed, pressed component 8 on first swivel arm is pressed on work piece 12 by top, the location component 9 of the 2nd swivel arm front end stretches into inner plate of car door and the neutral gear of outside plate stiffener, upwards it is pressed in from below on workpiece, it is achieved that to the location (as shown in Figure 4) of workpiece. Simultaneously, the limited block 11 on lower link is conflicted with ceiling substrate position portion 10, and restriction mechanism rotates further.

When welding completes to need said mechanism to open, described cylinder piston rod shrinks, and the pressed component on swivel arm and location component are deactivated region, can not interfere the taking-up of part.
