A rotating stand which can rotate relative to the support is arranged between the upper support and the lower support in a supported mode through a bearing. The outer end of a piston rod which is matched with the driving cylinder is connected with the rotating stand through a connector. A platform is fixedly arranged above the rotating stand. A limiting piece is arranged between the platform or the rotating stand and the support, wherein the limiting piece comprises a limiting cylinder which is mounted on the support, a limiting hole which is matched with a piston rod of the limiting cylinder is formed in the side face of the platform, and the support is fixedly provided with a fixing limiting block which is matched with the rotating stand. The switching device for fixing the welding gun can drive the welding gun to rotate so that welding of two positions can be achieved, two welding gun fixing mechanisms do no need to be arranged, the overall structure of a production line is simplified, relevant parts are few, and equipment cost is lowered.

Description

Be used for the fixedly switching device shifter of welding gun

Technical field

The utility model relates to a kind of setting tool parts of robot, and is particularly a kind of for the fixing switching device shifter of welding torch position conversion of robot.

Background technology

At present, on car body welding producing line, along with improving constantly of mechanization rate, the application that the part repair welding is grabbed by robot gets more and more.The situation that automobile factory is met through regular meeting: all solder joints can be with same welding gun being welded (determining according to pressure and workpiece shape); but because the limitation in 6 joints of robot; can't be by 1 fixedly real welding that realizes having a few of welding gun; must use 2 identical fixedly welding gun; be chosen in different positions, to reach the purpose of robot welding.Make the integral body equipment complexity that is welded, parts are many.

Summary of the invention

The purpose of this utility model provide a kind of make whole welding and assembling production lines simplified equipment, associated components few, support the fixedly switching device shifter of welding gun that is used for that weldering device can be realized changing, a rifle is dual-purpose, overcome the deficiencies in the prior art.

Of the present utility model for the fixing switching device shifter of welding gun, comprise base, be provided with support at base, at support driving cylinder and the upper bracket that is oppositely arranged up and down and undersetting are installed, having by bearings between upper bracket and undersetting can be with respect to the pivoted frame of support rotation, join by connector and pivoted frame with the external end head that drives the piston rod that cylinder matches, in the pivoted frame upper fixed platform is arranged, establish locating part between platform or pivoted frame and the support.

Of the present utility model for the fixing switching device shifter of welding gun, wherein said locating part comprises rack-mount spacing cylinder, be provided with the spacing hole that the piston rod with spacing cylinder matches in the side of platform, the fixedly limited block that matches with pivoted frame is fixedly arranged at support.

Of the present utility model this device can drive welding gun and rotate for the fixing switching device shifter of welding gun, realizes the welding of two positions, need not to arrange two fixedly welding gun mechanisms, and the production line overall structure is simplified, and associated components is few, and equipment cost reduces.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment.

The specific embodiment

As shown in Figure 1: 1 is base, and 2 for being fixedly connected on the support on the base 1.Be horizontally installed with the driving cylinder 3 that joins with pneumatic means at support 2.On support 2, be positioned at upper and lower to upper bracket 6 and the undersetting 12 of being fixedly connected, having by bearings between upper bracket 6 and undersetting 12 can be with respect to the pivoted frame 11 of support 2 rotations.Be connected with connector 5 by bearing pin with the external end head that drives the piston rod that cylinder 3 matches, connector 5 is fixedlyed connected with pivoted frame 11.When driving cylinder 3 actions, piston rod drives connector 5 and pivoted frame 11 rotates with respect to support 2.In pivoted frame 11 upper fixed platform 8 is arranged, establish locating part between platform 8 and the support 2, locating part also can be located between pivoted frame 11 and the support 2.This locating part comprises and is installed in the spacing cylinder 10 that joins with pneumatic means on the support 2, be respectively equipped with first spacing hole 7 and second spacing hole 9 at the side of platform 8 both direction, first spacing hole 7 and second spacing hole 9 match with the spacer pin of the piston rod end of spacing cylinder 10, after pivoted frame 11 and platform 8 rotate in place, can cross spacing cylinder 10 actions, make spacer pin insert spacing hole and carry out spacing locking.At support 2 the fixedly limited block 4 that matches with pivoted frame 11 is arranged fixedly, fixedly limited block 4 can be used as the stop collision block of pivoted frame 11 when rotateing in place, and fixed block 4 has two, lays respectively at the stop place that the both direction of pivoted frame 11 rotates.

Welding gun mechanism is installed on the platform 8 by bolting, during operation, carry out the spacing of a position by locating part, welding gun can be to the workpiece operation that is welded, after intact, action by spacing cylinder 10 is removed spacing, drive pivoted frame 11 rotations, platform 8 simultaneously by driving cylinder 3 then, welding gun rotates thereupon, is undertaken spacing by spacing cylinder 10 again when turning to another position, again workpiece is carried out weld job, this device can be realized the welding action of two positions, can save a fixedly welding gun mechanism, and the production line overall structure is simplified, associated components is few, and equipment cost reduces.
