[0029] like Figures 1 to 5 As shown, a welding positioner for a robotic welding workstation according to one embodiment of the present invention includes: a support chassis 1 and a moving adjustment mechanism 2.

[0030] like Figures 1 to 2 As shown, a welding positioner body 101 is mounted on a support chassis 1. Multiple storage slots 103 are carved into the bottom of the support chassis 1 to provide space for the retractable support column 201 and auxiliary pulleys 204. This prevents the auxiliary pulleys 204 from contacting the ground when not in use, thus ensuring the stability of the welding positioner body 101 during operation. Preferably, a controller 102 is mounted on the welding positioner body 101. The controller 102 is electrically connected to multiple lifting drive components 205 to control the simultaneous start and stop of multiple electric hydraulic jacks 210, thereby ensuring the stability of the support chassis 1 and the welding positioner body 101 and reducing the probability of tilting.

[0031] Specifically, the side wall of the storage groove 103 is drilled with threaded holes for screwing in the limiting and fixing screw 208, thereby making it difficult for the limiting and fixing screw 208 to move, and facilitating the limiting or fixing of the support column 201 and the auxiliary pulley 204.

[0032] like Figures 1 to 3As shown, the movement adjusting mechanism 2 is mounted on the support chassis 1, and the movement adjusting mechanism 2 comprises a support column 201 for supporting the auxiliary pulley 204 so as not to easily fall off, and the support column 201 is provided with a through hole for facilitating the passing of the limiting fixing screw 208, so that the limiting fixing screw 208 fixes the support column 201, and the support column 201 is not easy to rotate again. The rotating support bolt 202 is rotatably connected in the support column 201, so as to facilitate the rotation of the auxiliary pulley 204, thereby facilitating the adjustment of the direction during movement.

[0033] As shown in Figures 1 to 5 The rotating support bolt 202 is fixedly connected with the fixed sleeve ring 203, the fixed sleeve ring 203 is rotatably connected with the auxiliary pulley 204, for supporting the support chassis 1 and the welding positioner main body 101, so as to facilitate movement, and the sidewall of the support chassis 1 is provided with a plurality of lifting driving assemblies 205 for pushing the support chassis 1 and the welding positioner main body 101 to rise, thereby facilitating the adjustment of the position of the auxiliary pulley 204.

[0034] The end of the support column 201 away from the auxiliary pulley 204 is rotatably connected with the rotating support rod 206, both ends of the rotating support rod 206 are fixed to the inner wall of the storage groove 103, for supporting the support column 201, so that the support column 201 is not easy to fall off, and the support column 201 is facilitated to rotate, thereby realizing the rotation and falling of the support column 201 and the auxiliary pulley 204.

[0035] As shown in Figures 1 to 3 The end of the rotating support bolt 202 away from the auxiliary pulley 204 is arranged in the support column 201. The end of the rotating support bolt 202 arranged in the support column 201 is rotatably connected with the support bearing 207 between the support column 201, for fixing the rotating support bolt 202, so that the rotating support bolt 202 is not easy to fall off, and the rotating support bolt 202 is facilitated to rotate, thereby facilitating the adjustment of the direction of the support chassis 1 and the welding positioner main body 101 during movement.

[0036] In addition, the fixed sleeve ring 203 and the auxiliary pulley 204 are fixedly provided with the fixed bearing 212, for facilitating the rotation of the auxiliary pulley 204, thereby facilitating the movement of the support chassis 1 and the welding positioner main body 101, facilitating operation and reducing pushing pressure.

[0037] As shown in Figures 1 to 3As shown, a plurality of limiting fixing screws 208 matched with the through holes are inserted on the support base 1, one end of the limiting fixing screw 208 is threadedly connected with the support base 1, and is threadedly connected with the receiving groove 103 at the other end, thereby playing a limiting blocking role when the support column 201 and the auxiliary pulley 204 are retracted in the receiving groove 103, so that the support column 201 and the auxiliary pulley 204 are not easy to rotate and fall down, thereby maintaining the stability of the support base 1 and the welding positioner main body 101. When the auxiliary pulley 204 is used to support the support base 1 and the welding positioner main body 101, the limiting fixing screw 208 passes through the through hole of the support column 201, so that the support column 201 is not easy to rotate and move, thereby achieving the fixing effect.

[0038] As shown in the Figures 1 to 5 Lifting drive assembly 205 includes a fixed side block 209 for fixing the electric hydraulic jack 210, so that the electric hydraulic jack 210 is not easy to fall off or be damaged, and a plurality of fixed side blocks 209 are fixed on the side wall of the support base 1. The electric hydraulic jack 210 is installed in the fixed side block 209, which is used to control the telescopic movement of the push plate 211, thereby facilitating the movement of the support base 1 and the welding positioner main body 101.

[0039] Specifically, the electric hydraulic jack 210 is installed with a push plate 211 for pushing the ground, so that the support base 1 and the welding positioner main body 101 are raised, thereby facilitating the rotation of the auxiliary pulley 204. The bottom of the fixed side block 209 is flush with the bottom of the support base 1, which is used to increase the support area, thereby improving the stability of the support base 1 and the welding positioner main body 101 during work.

[0040] Specifically, when it is necessary to adjust the position of the support base 1 and the welding positioner main body 101, the worker controls the plurality of electric hydraulic jacks 210 through the controller 102 to start, so that the electric hydraulic jack 210 controls the extension of the push plate 211, thereby enabling the support base 1 and the welding positioner main body 101 to move away from the ground;

[0041] At this time, the limiting fixing screw 208 is rotated to be taken out, so that the support column 201 and the auxiliary pulley 204 rotate and fall down due to gravity, and then the limiting fixing screw 208 is inserted and passes through the through hole on the support column 201, and then one end of the limiting fixing screw 208 is threadedly connected with the support base 1, so that the support column 201 cannot rotate any more, thereby fixing the position of the auxiliary pulley 204, and then the push plate 211 is retracted through the electric hydraulic jack 210, so that the plurality of auxiliary pulleys 204 support the support base 1 and the welding positioner main body 101, thereby facilitating the movement thereof;

[0042] After moving to the designated position, the worker starts the electric hydraulic jack 210 again, so that the support chassis 1 and the welding positioner body 101 are lifted, then the support chassis 1 and the welding positioner body 101 are supported by the pushing disc 211, and then the limiting fixing screw 208 is taken out by rotating, at this time, the auxiliary pulley 204 and the support column 201 are pushed to make them all retract into the storage slot 103, then the limiting fixing screw 208 is inserted, at this time, the limiting fixing screw 208 will block the rotation of the auxiliary pulley 204 and the support column 201, finally, the pushing disc 211 is controlled to retract, so that the fixed side block 209 and the bottom of the support chassis 1 are in contact with the ground, and the overall movement of the device is realized.
