Abstract
The utility model belongs to the field of welding jigs, and particularly relates to a welding clamping mechanism capable of self locking. The welding clamping mechanism capable of self locking comprises a support seat, an air cylinder, a T-shaped compression rod, a connecting rod, an L-shaped connecting rod and a support connecting rod. The support seat is movably connected with a vertical bar of the T-shaped compression rod and fixedly connected with the support connecting rod. The connecting rod is movably connected with the L-shaped connecting rod which is movably connected with the support connecting rod and a piston rod of the air cylinder. The air cylinder is movably connected with the support seat. A compression adjusting block is arranged at one end of a cross bar of the T-shaped compression rod, and the other end of the cross bar is movably connected with the connecting rod. The turning portion of the L-shaped connecting rod is movably connected with the connecting rod. A limiting block is disposed in a position of the support seat and the position is close to the L-shaped connecting rod. When the welding clamping mechanism capable of self locking is used, ineffective clamping cannot be caused by transient air source break-off at the time of clamping of a product, meanwhile, the product can be prevented from being compressed and deformed due to excessive pressure.
Description
Technical field
The utility model belongs to the weld jig field, relates in particular to a kind of band self-locking weld clamp mechanism.
Background technology
During auto industry was made in modern times, anchor clamps were widely used in welding process, and the precision of weld jig has direct influence to the crudy of product.Therefore need need again simultaneously when compressing, avoid pressure to cross the compressive strain of senior general's product in clamping.Present mechanism also can be owing to of short duration source of the gas interrupts losing efficacy.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, and a kind of band self-locking weld clamp mechanism is provided, and raising work is convenient.
In order to realize the purpose of the utility model, the technical scheme of the utility model is:
A kind of band self-locking weld clamp mechanism comprises bearing and cylinder, T shape compressor arm; Connecting rod, L shaped connecting rod, support link; The montant of said bearing and said T shape compressor arm flexibly connects, and said bearing is fixedly connected with said support link, and said connecting rod and said L shaped connecting rod flexibly connect; Said L shaped connecting rod and said support link flexibly connect, and the piston rod of said L shaped connecting rod and said cylinder flexibly connects, and said cylinder and said bearing flexibly connect; The cross bar one end setting of said T shape compressor arm compresses the adjustment piece; The cross bar other end and said connecting rod flexibly connect, and the turning point of said L shaped connecting rod and the flexible connection of said connecting rod are provided with limited block at said bearing near the position of said L shaped connecting rod.
Said bearing is provided with and supports the adjustment piece, and the said adjustment piece that compresses was adjusted piece and is the bolt connection being connected of said bearing with being connected with said support of said T shape compressor arm.
Said cylinder and said bearing flexibly connect point and are arranged at the cylinder place of leaning on said piston rod extending area.
Said support link vertically is welded on the said bearing.
The beneficial effect of the utility model is: make product when clamping, can not prevent because pressure is crossed the compressive strain of senior general's product simultaneously owing to of short duration source of the gas interrupts causing clamping losing efficacy.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Embodiment: referring to Fig. 1.
A kind of band self-locking weld clamp mechanism comprises bearing 1 and cylinder 9, T shape compressor arm 4; Connecting rod 5, L shaped connecting rod 6, support link 8; Said bearing 1 flexibly connects with the montant of said T shape compressor arm 4, and said bearing 1 is fixedly connected with said support link 8, and said connecting rod 5 flexibly connects with said L shaped connecting rod 6; Said L shaped connecting rod 6 flexibly connects with said support link 8, and said L shaped connecting rod 6 flexibly connects with the piston rod of said cylinder 9, and said cylinder 9 flexibly connects with said bearing 1; The cross bar one end setting of said T shape compressor arm 4 compresses adjustment piece 3; The cross bar other end and said connecting rod 5 flexibly connects, and the turning point of said L shaped connecting rod 6 and 5 flexible connections of said connecting rod are provided with limited block 7 at said bearing 1 near the position of said L shaped connecting rod 6.
Said bearing 1 is provided with and supports adjustment piece 2, and the said adjustment piece 3 that compresses was adjusted piece 2 and is the bolt connection being connected of said bearing 1 with being connected with said support of said T shape compressor arm 4.
Said cylinder 9 flexibly connects point with said bearing 1 and is arranged at the cylinder place of leaning on said piston rod extending area.
Said support link 8 vertically is welded on the said bearing 1.
Operation principle: through the motion of cylinder piston rod; When one side of connecting rod 5, support link 8 and L shaped connecting rod 6 during at straight line; Be T shape compressor arm 4 and the tie point of connecting rod 5, connecting rod 5 and the tie point of L shaped connecting rod 6, L shaped connecting rod 6 tie point with support link 8, these 3 o'clock on a line in, T shape compressor arm 4 compacted position that reaches capacity; This moment, mechanism reached self-locking state, can be owing to of short duration source of the gas interrupts losing efficacy.Have only motion, could T shape compressor arm 4 be rotated, discharge clamped condition through the L shaped connecting rod 6 that is connected with cylinder piston rod.Cause product distortion to prevent because clamping pressure is excessive through the limited block on the bearing 17.Compress thickness through adjusting to support adjustment piece 2 and bearing 1 and T shape compressor arm 4 and compress the pad of adjusting 3 of pieces with height and position and the sealing of adjusting product.
What the embodiment of the utility model announced is preferred embodiment; But be not limited thereto, those of ordinary skill in the art is very easily according to the foregoing description; Understand the spirit of the utility model; And make different amplifications and variation, but only otherwise break away from the spirit of the utility model, all in the protection domain of the utility model.
