The technical scheme that the present invention adopts is:

The present invention includes oil cylinder, two rotating shafts, two clamp arms, two swivel joints, two passive chain gear apparatus, two clamps, crank, two drive sprockets and two by movable sprocket; One end level of oil cylinder is installed on the slide of marking machine before the marking head; The other end of oil cylinder connects with the hole of crank one end through bearing pin; Key joint is used in the hole of the crank other end and first rotating shaft upper end; First rotating shaft is attached on the slide through a bearing and a bearing block, and the first rotating shaft lower end is passed a Γ shape clamp arm horizontal component and first and connect by movable sprocket; Second rotating shaft and first shaft parallel are installed, and are attached on the slide through another bearing, another bearing block, and the second rotating shaft lower end is passed the 2nd Γ shape clamp arm horizontal component and second and connect by movable sprocket; Two Γ shape clamp arm vertical components are respectively installed with clamp; The clamp upper end is separately installed with drive sprocket; Chain through separately is connected to passive chain gear apparatus and forms driving-chain separately respectively; The clamp of Γ shape clamp arm vertical component and clamp arm separately be for being rotatably assorted, and two Γ shape clamp arm horizontal components have sector gear near the end face of slide, and two sector gears can be meshing with each other; On two Γ shape clamp arm horizontal components, the swivel joint that guide line is used is installed respectively.

Described two passive chain gear apparatus structures are identical, include bearing, end cap, back-up ring, spacer ring and by movable sprocket; Bearing inner race and spacer ring are fixed in the rotating shaft with end cap and securing member, bearing outer ring with connect by movable sprocket, and fix with back-up ring, connected firmly by movable sprocket outer face and slide.

The beneficial effect that the present invention has is:

The principle that the present invention utilizes endogenetic process to offset, the centering clamp mechanism of employing hydraulic drive has reduced the marking impulsive force to the body shock and vibration, has improved the stability of equipment, has effectively prolonged service life of equipment.The centering clamp mechanism is simple and reliable, compact conformation, and control is convenient, is easy to safeguard.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Like Fig. 1, Fig. 2, shown in Figure 3, the present invention includes oil cylinder 2, two rotating shafts 3, two clamp arms 4, two swivel joints 5, passive chain gear apparatus 6, two clamps 7, crank 10, two drive sprockets 11 and two by movable sprocket 18; One end level of oil cylinder 2 is installed on the slide 1.1 of marking machine before the marking head 8; The other end of oil cylinder 2 connects with the hole of crank 10 1 ends through bearing pin; Key joint is used in the hole of crank 10 other ends and first rotating shaft, 3 upper ends; First rotating shaft 3 is attached on the slide 1.1 through a bearing 15 and a bearing block, and first rotating shaft, 3 lower ends are passed Γ shape clamp arm 4 horizontal components and first and connect by movable sprocket 18; Second rotating shaft 3 and first rotating shaft, 3 parallel installations are attached on the slide 1.1 through another bearing 15, another bearing block, and second rotating shaft, 3 lower ends are passed the 2nd Γ shape clamp arm 4 horizontal components and second and connect by movable sprocket 18; Two Γ shape clamp arm vertical components are respectively installed with clamp 7; Clamp 7 upper ends are separately installed with drive sprocket 11; Chain through separately is connected to passive chain gear apparatus and forms driving-chain separately respectively; The clamp of Γ shape clamp arm vertical component and clamp arm 4 separately be for being rotatably assorted, and two Γ shape clamp arm horizontal components have sector gear near the end face of slide 1.1, and two sector gears can be meshing with each other; On two Γ shape clamp arm 4 horizontal components, the swivel joint 5 that guide line is used is installed respectively.

As shown in Figure 4, described two passive chain gear apparatus structures are identical, include bearing 12, end cap 13, back-up ring 14, spacer ring 16 and by movable sprocket 18; Bearing 12 inner rings and spacer ring 16 usefulness end caps 13 are fixed in the rotating shaft
