Ring-shaped conveying chain workpiece draw gear
The utility model relates to a kind of ring-shaped conveying chain workpiece draw gear, can be widely used on the endless chain travel line of machine manufacture and shipbuilding industry.
As everyone knows, the ring-shaped conveying chain in the past draws in the process of workpiece, generally all is that a fixing trailer coupling is established in certain fixing position on the endless chain travel line, the cost height, and efficient is low.
Summary of the invention
The purpose of this utility model is: a kind of ring-shaped conveying chain workpiece draw gear is provided, installs fixed traction mechanism at fixed bit, cost height, inefficient problem to solve existing conveyer chain.
The technical solution of the utility model is: adopt the trolley type structure, the front end face and the workpiece of dolly are fixed, and the side and the ring-shaped conveying chain of dolly are fixed together, and lead with 4 little track adjusting wheels.
The front end face of dolly is visited in workpiece, and the upper surface of the lower surface of workpiece and dolly table top is fitted, and withstands and clamps with the upper surface of fastening bolt with workpiece then, and dolly and workpiece are become one.
With the endless chain pull-up in the channel-section steel, ride in the groove of little vehicle body side, then the cam lock piece is pushed in the middle of 2 annular chain links; The axle that the hole of cam lock piece is passed on the little car body links together with little car body, and the lower end of cam lock piece is stuck in the middle of 2 chain links, and like this, little car body and ring-shaped conveying chain just become one.
As shown in Figure 3, long and two-short dash line represents that the cam lock piece advances the initial position 1 of ring-shaped conveying chain, the residing locked position 2 of cam when heavy line is represented the ring-shaped conveying chain motion.The arrow direction is the sense of motion of ring-shaped conveying chain among the figure.Ring-shaped conveying chain moves along direction as shown, and when the cam lock piece was in this position, dolly side and ring-shaped conveying chain bar were fixed.
Otherwise,, then the cam lock piece is turned over the turnback angle and installs if change the sense of motion of ring-shaped conveying chain.The locking principle as above.
The utility model has the advantages that: chain movement (advance or retreat), workpiece be movement therewith (advance or retreat) also, thereby has promptly simply realized the displacement of workpiece again quickly.The fastening convenience of the utility model, light and handy, nimble, can realize carrying and traction in the optional position on chain.

The specific embodiment
Dolly body 1 is ridden over the centre of two channel-section steel 6 supports, by 4 track adjusting wheel 3 controlling parties to; One end of dolly body 1 is visited in workpiece 7, and spy advances apart from clamping workpiece 7 with fastening bolt 4 to be as the criterion, and with fastening bolt 4 workpiece 7 is fixed on the dolly body 1 then; Endless chain 5 pull-ups with 6 li in channel-section steel, ride over 8 li of dolly body 1 lateral grooves, then cam lock piece 2 is pushed in the middle of the adjacent link of endless chain 5, the axle 9 that the hole of cam lock piece 2 is passed on the dolly body 1 links together with little car body, the lower end of cam lock piece 2 is stuck in the middle of 2 chain links, like this, little car body and endless chain just become one; Starter motor, the driven by motor sprocket wheel, sprocket wheel drives chain, and chain drives dolly, and dolly drives workpiece.So just realized advancing or retreating of workpiece.
