During the welding, set up back panel in back panel bearing frame and fixed by compressing tightly the subassembly, weld by welding robot, when needs upset, second servo motor work drives the pivot rotation, makes back panel bearing frame upset, need not artifical upset to rotation angle control is accurate. After welding of a set of back panel welding is accomplished, first servo motor work drives the roating seat through high-accuracy decollator and rotates 180 degrees, and the robot department that welds is rotatory to welding with another group welding frock improves work efficiency, and high-accuracy decollator control accuracy is high and have self-locking function.

The pressing assembly comprises a mounting seat, a handle and a pressing rod, wherein the mounting seat comprises a base plate and a connecting plate which are integrally arranged, the base plate is connected with a back panel supporting frame, one end of the handle is integrally provided with an eccentric block, the eccentric block is hinged with the connecting plate through a hinge shaft, the hinge shaft and the eccentric block are eccentrically arranged, the eccentric block forms a long radius part and a short radius part, and after the handle rotates, the long radius part of the eccentric block abuts against the base plate; one end of the pressure lever is connected with the handle, the other end of the pressure lever is connected with the pressure head, and the pressure head is pressed on the back coaming. When compressing tightly, operating handle drives depression bar and pressure head and presses to the back shroud, because the major radius portion of eccentric block is supporting the bottom plate, realizes fixing, therefore the pressure head is pressing the back shroud to the pressure head also can not loosen when back shroud bearing frame overturns.

In order to avoid abrasion of the back panel, a rubber protection pad is connected to the pressure head.

The pressure head is connected with a screw rod, and the screw rod is in threaded connection with a pressure rod. The position of the ram is conveniently adjusted to more properly press against the back panel.

In order to avoid the spark from splashing to the other side during welding, a baffle plate which is vertically arranged is connected above the rotating seat, and the length direction of the baffle plate is consistent with that of the rotating seat.

Detailed Description

As shown in fig. 1 to 3, for back panel welding revolving stage, including unable adjustment base 7 and roating seat 3, roating seat 3 is the cuboid and sets up in unable adjustment base 7's top, connects high-accuracy decollator 9 on unable adjustment base 7, and the input shaft of high-accuracy decollator 9 is connected first servo motor 8, and the output shaft of high-accuracy decollator 9 is connected with roating seat 3, and high-accuracy decollator 9 control accuracy is high and have self-locking function. The baffle 1 which is vertically arranged is connected above the rotating seat 3, and the length direction of the baffle 1 is consistent with that of the rotating seat 3.

All set up welding frock 11 in roating seat 3 front and back both sides, welding frock 11 includes two side levers 12 and back panel bearing frame 2, and both ends about roating seat 3 are connected respectively to two side levers 12, and back panel bearing frame 2 sets up between two side levers 12, and pivot 4 is all connected at both ends about back panel bearing frame 2, and pivot 4 passes through bearing 6 and sets up on side lever 12, and second servo motor 5 is connected to one of them pivot 4.
