Detailed Description

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a both sides centre gripping type welding frock, comprises a workbench 1, sliding fit has two slides 2 on the workstation 1, fixedly connected with supporting seat 5 on the slide 2, supporting seat 5 one side is equipped with two holders 6, holder 6 and supporting seat 5 of downside are connected fixedly, fixed connection's slider 12 and supporting seat 5 sliding fit are passed through to 6 one end of holder of upside, sliding connection has two racks 13 in the slider 12, rack 13 is connected fixedly with supporting

seat

5, 13 one side joint cooperation of rack has pinion rack 14, be equipped with adjustment mechanism 15 between two pinion rack 14, adjustment mechanism 15 includes the pivot 1501 of being connected with slider 12 rotation, the pivot 1501 middle part is rotated and is connected with driving lever 1503, equal sliding connection has connecting rod 1504 at pivot 1501 both ends, connecting rod 1504 is connected fixedly with pinion rack 14.

In this technical scheme, driving lever 1503 can drive pivot 1501 to rotate, pivot 1501 can drive the pinion rack 14 of both sides with the cooperation of connecting rod 1504 and slide, pinion rack 14 cancels the contact back with rack 13, slide 12 can freely slide on rack 13, slide 12 drives the holder 6 decline of upside, two holders 6 cooperation carry out the centre gripping to welding material, reverse rotation driving lever 1503 can drive pinion rack 14 and rack 13 joint, thereby prevent that slide 12 from sliding, make two holders 6 stable to the material centre gripping, be close to each other through removing two sliders 2, realize two welding material docks.

Specifically, the workbench 1 is rotatably connected with a bidirectional screw rod 3, two ends of the bidirectional screw rod 3 are fixedly connected with rotating wheels 4, and the bidirectional screw rod 3 is in threaded fit with the sliding seat 2.

In this solution, the rotating wheel 4 drives the bidirectional screw 3 to rotate, thereby driving the two sliders 2 to approach each other or move away from each other.

Furthermore, the clamping holders 6 are rotatably connected with a plurality of roll shafts 7, and all the roll shafts 7 in each clamping holder 6 are arranged in a zigzag shape.
