Coolant liquid in liquid pipe is sprayed by nozzle, and coolant liquid is sprayed on the weld of aviation plank and is cooled down to it.When
When two motors are closed, coolant liquid also just stops spraying.Weld is caused to deform when in this way, can prevent aviation plank from rotating.
Because further including having connecting rod and draw ring, connecting rod is installed in the middle part of first bearing seat leading flank, connecting rod front end is equipped with
Draw ring, the personnel of being operated first hold draw ring and connecting rod are pulled to move forward, and connecting rod, which moves forward, drives first bearing seat to move forward,
And the first roller is driven to move forward.When aviation plank is located on rear side of the first roller, you can unclamp draw ring, and then the first roller to
Movement tentatively clamps aviation plank afterwards.In this way, can make operating personnel that first bearing seat more easily be pulled to drive the first roller
It is mobile.
Because further including having 3rd bearing seat, the second shaft and second tin roller, front side is provided with groove, groove at the top of support plate
Interior leading flank top and trailing flank top is all evenly spaced is equipped with 3rd bearing seat, connects between the 3rd bearing seat of front and rear sides
It is connected to the second shaft, second tin roller is installed, second tin roller is located at below the first roller, when aviation plank quilt in the middle part of the second shaft
When first roller tentatively clamps, aviation sheet material base is contacted with second tin roller, and then when operating personnel push left and right sides aviation
Plank moves inward, and aviation plank moves on second tin roller, so second tin roller can make aviation plank move when it is more smooth.
(3) advantageous effect
The present invention can be clamped aviation plank fixation by clamping device, and prevent aviation plank when welding from occurring
It is mobile, and by rotating device, dynamic by aviation plank progress turn-over without human hand, having reached, aviation plank can be fixed,
And it is not easily shifted do not influence welding effect, also without the dynamic effect for carrying out turn-over to aviation plank of human hand.
