The utility model relates to a small concrete mixer blade and cylinder combined welding equipment, which includes a rotary lifting device, a blade placement robot, a blade welding robot and a blade assembly device. The rotary lifting device is installed on the foundation pit, the rotary lifting device is installed with a blade assembly device, and the blade placement device and the blade welding device are installed on the ground respectively.
The equipment includes a rotary lifting device, a blade placement robot, a blade welding robot and a blade assembly device; All parts cooperate with each other, and workers are no longer required to weld blades in the cylinder. It can realize the automatic production of combined welding of blades and cylinder of small concrete mixer, greatly improve productivity, meet the requirements of mass production in the factory, and has a broad market space.
The preferred scheme of the invention is:
The rotary lifting device comprises a base, a lifting mechanism, a rotary mechanism and a cylinder support mechanism; The two ends of the base are respectively provided with lifting mechanisms, the lifting mechanisms on the left and right sides are connected through the rotary mechanism, and the lifting mechanism is sliding connected with the rotary mechanism; The cylinder support mechanism is arranged on the top of the lifting mechanism.
The cylinder supporting mechanism comprises a supporting rod and a hydraulic cylinder; The support rod is arranged on the top of the lifting mechanism, and a hydraulic cylinder is arranged on the support rod.
The cylinder supporting mechanism comprises a supporting frame, a screw rod, a sliding seat and a power structure; The support frame is installed on the top of the lifting mechanism, and the upper part of the support frame is equipped with a sliding plate, which is provided with a sliding seat, which is sliding connected with the sliding plate, and the sliding seat is provided with an internal thread structure; A power structure is installed on the support frame, which is connected with the screw rod, and the screw rod is sleeved in the internal thread structure.
The rotary mechanism includes a tooling installation platform; The tooling installation platform includes a rotary platform, a tooling positioning structure and a tooling pressing structure; The upper surface of the rotary platform is respectively provided with a plurality of tooling positioning structures and tooling pressing structures.
A chute is arranged on the clamping structure of the tooling, and a fixture is installed on the chute, and the chute is slidably connected with the fixture.
The blade assembly device comprises a tooling body and a blade tooling fixture; The main body of the tooling is a hollow cylinder, and the outer side of the hollow cylinder is provided with blade tooling fixtures, which are spirally distributed.
The working process of the small concrete mixer blade and cylinder combined welding equipment is as follows:
The front and rear sides of the equipment are respectively equipped with blade welding robots, which can complete the simultaneous welding of two groups of blades at the same time, form a double logarithmic spiral curve, and improve work efficiency.
Two blades are symmetrically distributed. The machine places the blades on the blade tooling fixture. The surface of the electric permanent magnet installed on the fixture is completely fitted with the blades, and the blades are sucked and positioned by electrical control; Then, the blade placement robot places the second blade on the blade tooling fixture, and the electric permanent magnet positions the blade; Then, the blade welding robot spot weld the weld; Then, the rotary lifting device acts, and the trapezoidal lead screw is driven to rotate by the servo motor of the lifting mechanism 8, so that the rotary mechanism drops by a corresponding distance.
At the same time, the second servo motor on the rotary mechanism drives the rotary platform and rotates the tooling installation table counterclockwise by a corresponding angle to make the next blade positioning tooling reach the specified position. After the blade placement robot places the blade in place, the blade welding robot spot welds the weld; Repeat the above actions successively until all blades are spot welded. The rear blade welding robot fully welds the weld, and the rotary lifting device acts in the opposite direction to make the weld reach the welding position in turn and complete the full welding.
