Description

Robot welder

Technical field

It the utility model is related to field of welding devices, and in particular to a kind of robot welder, be particularly suitable for use in steel Tube frame is welded.

Background technology

During using steel-pipe welding into steel framework, as shown in Fig. 2 a section steel pipe is placed in frame first, splice Into the shape of framework, steel pipe is gripped by multiple cylinders and fixed block corresponding with cylinder, then utilizes weldering Welding manipulator is overturn to being welded at fastener for connection, and by motor control frame, and the bottom at fastener for connection is also carried out Welding, is finally completed the welding of steel framework.

But in actual use, because the diameter of steel tube required for different frames is different, in cylinder to being relatively large in diameter When steel pipe is clamped, the latter half of steel pipe can only be often clamped, this results in steel pipe clamping and is not sufficiently stable.

Utility model content

The purpose of this utility model is to provide a kind of robot welder, and its advantage is that the clamping to steel pipe is more steady It is fixed.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of robot welding is set Standby, including frame, the frame is provided with the cylinder of some vertical and horizontal arrangement, and the is fixed with the piston rod of the cylinder One grip block, is fixed with some second grip blocks in the frame, a pair of first grip block and second grip block 1 It should set, rotating shaft is fixed with the frame, be additionally provided with the motor for controlling the axis of rotation, the frame side is provided with welding Manipulator, the welding manipulator are slidably connected on guide rail, and some hold-down mechanisms, the compacting machine are additionally provided with the frame Structure includes fix bar, rotor plate and clamping screw, and the fix bar is fixed in the frame vertically, and described rotor plate one end is Annulus, the annulus are rotatably connected in the fix bar, and the rotor plate other end lower surface contradicts with steel pipe upper surface, institute State clamping screw the annulus and the fix bar are locked, the edge of the frame is provided with gripper cylinder, the clamping Cylinder is connected with the conflict bar for being contradicted to steel pipe side, and described one end for contradicting bar is arc-shaped.

Pass through above-mentioned technical proposal, by the steel pipe for preparing welding according to the shaped formation of framework, it is placed in frame, drives Cylinder, steel pipe is clamped by the first grip block and the second grip block, then rotates rotor plate so that the following table of rotor plate Face and the upper surface of steel pipe contradict, and are fixed rotor plate by clamping screw, and rotor plate compresses steel pipe in the vertical direction, So that the clamping to steel pipe is more firm, gripper cylinder driving contradicts bar and moved towards steel pipe, contradicts the circular arc of boom end Shape just contradicts with steel pipe side, so as to improve the stability of steel pipe clamping.

The utility model is further arranged to：Center line symmetrical setting of the hold-down mechanism on the frame.

Pass through above-mentioned technical proposal, the symmetrical center line symmetrical setting on frame of hold-down mechanism, so as to steel pipe both ends by Thrust to pressing plate is more uniform, and steel pipe clamps more stable in frame.

In summary, the utility model has the advantages that：

1st, the horizontal direction of steel pipe is clamped with the second grip block by the first grip block, by rotor plate to steel pipe Vertical direction compressed, the side of steel pipe is contradicted by contradicting bar so that steel pipe in frame regularly more It is stable, the possibility that steel pipe is moved is reduced when welding especially overturning of machine frame, so that welding is more accurate；

2nd, rotor plate is locked by bolt, fixation.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment：Robot welder, as shown in figure 1, including frame 1, the end of frame 1 is fixed with rotating shaft 12, rotating shaft 12 are connected with motor 13, and the side ground of frame 1 is provided with the guide rail 21 parallel with frame 1, weldering is slidably connected on guide rail 21 Welding manipulator 2, frame 1 are provided with some through holes 11 welded for welding manipulator 2 to the reverse side of steel pipe 7.

The cylinder 3 of some vertical and horizontal arrangements is fixed with frame 1, the first folder is fixed with the piston rod 31 of cylinder 3 Block 32 is held, some the second grip blocks 33 that setting is corresponded with the first grip block 32 are fixed with frame 1, such as Fig. 3 and Fig. 4 institutes Show, some hold-down mechanisms 4, center line symmetrical setting of the hold-down mechanism 4 on frame 1 are additionally provided with frame 1.Hold-down mechanism 4 wraps Fix bar 41, rotor plate 42 and clamping screw 43 are included, fix bar 41 is fixed in frame 1 vertically, and the one end of rotor plate 42 is annulus 421, annulus 421 is rotatably connected in fix bar 41, and the other end lower surface of rotor plate 42 contradicts with the upper surface of steel pipe 7, and passes through Annulus 421 and fix bar 41 are locked by clamping screw 43, limit the rotation of rotor plate 42.

The edge side wall of frame 1 is fixed with gripper cylinder 6, and gripper cylinder 6 is connected with for being contradicted to the side of steel pipe 7 Conflict bar 61, the one end for contradicting bar 61 be arc-shaped, and by the driving of gripper cylinder 6, conflict bar 61 moves towards steel pipe 7, The side of steel pipe 7 is contradicted by one end of arc-shaped.

The course of work：As shown in figure 5, the steel pipe 7 for preparing welding is placed on first according to the shaped formation of framework first Between the grip block 33 of grip block 32 and second, then the first grip block 32 is controlled to be moved towards the second grip block 33 by cylinder 3, So as to be clamped to steel pipe 7；Then rotor plate 42 is rotated, and the lower surface of connecting plate 42 and the upper surface of steel pipe 7 are contradicted, profit Annulus 421 and fix bar 41 are locked with clamping screw 43, the rotation of rotor plate 42 is limited, by steel pipe 7 in vertical direction Upper compression；Finally bar 61 is contradicted using the driving of gripper cylinder 6 to move towards steel pipe 7, contradict the arc-shaped of bar 61 end just with The side of steel pipe 7 contradicts, and completes fixation of the whole steel framework in frame 1.
