[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] This utility model provides two technical solutions:

[0032] Figures 1 to 3 A first embodiment is shown: a bucket arm welding positioner, comprising:

[0033] The headstock 1 and tailstock 2 are arranged opposite to each other, and the tailstock 2 is slidably mounted on the ground rail 3;

[0034] The turntables 4 are rotatably mounted on the sides of the headstock 1 and the tailstock 2 close to each other, and the two turntables 4 are coaxially arranged;

[0035] The clamping components are respectively fixed on the sides of the two turntables 4 that are close to each other;

[0036] The rotating assembly is fixed on the head frame 1 and is used to drive the turntable 4 on the head frame 1 to rotate;

[0037] The locking mechanism is installed on the head frame 1 and is used to lock the rotating component.

[0038] The clamping assembly includes a crossbeam 5 fixed on the turntable 4, and the inner wall of the crossbeam 5 is rotatably connected to the bidirectional screw 6 through a bearing. Two clamping bars 7 are symmetrically slidably installed on the crossbeam 5, and the clamping bar 7 is threadedly connected to the bidirectional screw 6 through a threaded hole. One end of the bidirectional screw 6 passes through the crossbeam 5 and extends to the outside of the crossbeam 5, where a ratchet 8 and a turning handle 9 are fixed in sequence. A locking plate 10 is rotatably connected to the outer surface of the crossbeam 5 near the ratchet 8 through an axle pin. The locking plate 10 cooperates with the ratchet 8, and a spring 11 is installed between the outer wall of the crossbeam 5 near the locking plate 10 and the locking plate 10.

[0039] The rotating assembly includes a motor 12 fixed on the head frame 1, a gear 13 is fixed to the output end of the motor 12, and a ring gear 14 is fixed to the side of the turntable 4 on the head frame 1 close to the motor 12, and the gear 13 is meshed with the ring gear 14.

[0040] This application sets up a turntable 4, a crossbeam 5, a clamping bar 7, a ratchet 8, a locking plate 10 and a handle 9, so that by rotating the handle 9 in the direction of the ratchet 8, the spacing of the clamping bars 7 can be adjusted according to the size of the boom, so that the boom can be stably clamped between the two clamping bars 7.

[0041] Figures 4 and 5 A second embodiment is shown, the main difference from the first embodiment is that the locking mechanism includes a flip bar 15 rotatably connected to the outer wall of the head frame 1 through an axle pin, a tooth plate 16 is fixed to the side of the flip bar 15 close to the gear ring 14, the tooth plate 16 cooperates with the gear ring 14, and a flip assembly for driving the flip bar 15 to flip is fixed to the side of the upper end of the head frame 1 close to the flip bar 15.

[0042] The flip assembly includes an electric push rod 17 rotatably connected to the outer wall of the head frame 1 through an axle pin, and the extended end of the electric push rod 17 is rotatably connected to the outer wall of the flip bar 15 through an axle pin.

[0043] After the turntable 4 is driven to rotate by the motor 12, the boom located between the clamping bars 7 also rotates accordingly. This application positions the boom after rotation by setting a locking mechanism, thereby ensuring the stability of the boom flip angle and the work quality of the boom welding.

[0044] Working principle:

[0045] The headstock 1, tailstock 2 and ground rail 3 are all prior art and are not described in detail.

[0046] The turning handle 9 is turned to rotate the ratchet 8 in the direction of the locking plate 10. The spring 11 is simultaneously activated, and the bidirectional screw 6 is rotated, thereby driving the two clamping bars 7 to move closer to each other. The cooperation between the locking plate 10 and the spring 11 can effectively prevent the turning handle 9 and the ratchet 8 from being reversed, thereby ensuring that the clamping bar 7 stably clamps the bucket arm. By rotating the locking plate 10 to disengage the locking plate 10 from the ratchet 8, the turning handle 9 and the ratchet 8 can be reversed, thereby reversing the bidirectional screw 6 and causing the clamping bars 7 to move away from each other. Driving the ground rail 3 can move the tail frame 2 above the ground rail 3.

[0047] According to the size of the boom to be welded, the distance between the tailstock 2 and the headstock 1 is adjusted, and the distance between the clamping strips 7 is adjusted, so that the boom is clamped between the headstock 1 and the tailstock 2.

[0048] The electric push rod 17 is driven to extend to drive the flip bar 15 to flip, so that the tooth plate 16 on the flip bar 15 is away from the ring gear 14 to unlock the ring gear 14, and then the motor 12 is driven to rotate the gear 13 to turn the ring gear 14, and the turntable 4 drives the crossbeam 5 to rotate, and then drives the boom to rotate. When the boom rotates to the required angle, the motor 12 is turned off, and then the electric push rod 17 is retracted, the flip bar 15 is reversed, and the tooth plate 16 is abutted and locked with the ring gear 14; thereby ensuring the stability of the boom flip angle.
