In the above-described embodiments, between each welding post, be equipped with the rail for middle groove transport cart movement, wherein, between horizontal rail and longitudinal rail, be provided with certain difference in height.This difference in height is equal with the difference in height that lengthwise rows is walked between vehicle wheel component 26 with horizontal running wheel assembly 23.In actual mechanical process, in longitudinal walking process, first by locked for horizontal walking mechanism 5, longitudinal traveling mechanism 6 is walked on longitudinal rail.After treating that lengthwise rows is walked to put in place, remove the locking of horizontal walking mechanism 5, horizontal walking mechanism 5 is walked on horizontal rail.Because the difference in height between horizontal rail with longitudinal rail is equal with the difference in height that lengthwise rows is walked between vehicle wheel component with horizontal running wheel assembly, horizontal walking mechanism 5 can be walked after longitudinal traveling mechanism 6 puts in place stably.Because the weight of the intermediate channel of transport calculates with ton substantially, the horizontal walking mechanism 5 of rail and correspondence and longitudinal traveling mechanism 6 is used to be convenient to the movement of middle groove transport cart between each station.
Visible, in the present invention, by being equipped with rail between preparation station and each welding post, middle groove transport cart can be walked on rail.By horizontal walking mechanism and longitudinal traveling mechanism, intermediate channel is transported to each welding post from preparation station accurately, also can realizes the quick and precisely conveying of intermediate channel between each welding post.
In addition, on welds prepares station, in intermediate channel, on plate two ends, two positioning and clamping devices 3 fixed by clamping respectively, after on the welding post intermediate channel prepared on station being moved to other, taper locating hole can be utilized to realize accurately location and clamping intermediate channel.On preparation station, by the 3 pairs of intermediate channel clampings of positioning and clamping device.Then coordinated with the locating taper pin 11 on slipway mechanism 1 by the taper locating hole in positioning and clamping device 3, realize the location to intermediate channel.
Then lifting electric cylinder rises, and promotes the lifting pushing bracket 13 in main body 14, drives main body 14 to rise; Intermediate channel is taken out from preparation station; Then lifting electric cylinder declines, and pulls the lifting pushing bracket 13 in main body 14, drives main body 14 to decline.
By horizontal walking device and lengthwise rows walking apparatus with the use of, intermediate channel is transported on each welding post.Further, in the transportation of intermediate channel, positioning and clamping device 3 is all be clamped in intermediate channel, and operates together along with intermediate channel.
Move up and down positioning and clamping device 3 by main body 14 and elevating mechanism 2, realize the accurate location of positioning and clamping device 3 relative to intermediate channel at vertical direction.Move left and right positioning and clamping device 3 by slide unit and slipway mechanism 1, realize the accurate location to positioning and clamping device 3 in the horizontal direction.By the location to positioning and clamping device 3, so can intermediate channel accurately positioning and clamping in the operating position of each welding post.
Namely middle groove transport cart is by the accurate location of positioning and clamping device realization to intermediate channel, realizes the automatic transport fast and accurately of intermediate channel between each station by horizontal walking mechanism and longitudinal traveling mechanism.Thus realize the full process automatization of intermediate channel robot automatic welding production.Its advantage is, exactly intermediate channel is positioned on each station in robot automatic Arc Welding, thus realizes the automatic welding of robot.Each intermediate channel can realize accurately locating at three coordinate directions, and for the intermediate channel robot welding of same size, from second intermediate channel, robot starts just need not seek position, can directly operate.
In sum, the invention provides middle groove transport cart by the accurate location of positioning and clamping device realization to intermediate channel, realize the fast and accurately automatic transport of intermediate channel between each station by horizontal walking mechanism and longitudinal traveling mechanism.Thus realize the full process automatization of intermediate channel robot automatic welding production.Its advantage is, exactly intermediate channel is positioned on each station in robot automatic Arc Welding, thus realizes the automatic welding of robot.Each intermediate channel can realize accurately locating at three coordinate directions, and for the intermediate channel robot welding of same size, from second intermediate channel, robot starts just need not seek position, can directly operate.
The foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., be all included in protection scope of the present invention.
