Technical Field

[0001] The utility model relates to the technical field of non-standard structural parts, in particular to a positioning mechanism for welding non-standard structural parts. Background Art

[0002] Non-standard structural parts are those that cannot be manufactured according to existing standard specifications and must be customized to meet specific needs. They are widely used in various industries, such as machinery, automotive, aerospace, and chemical engineering, to meet the process requirements of specialized equipment, production lines, and industrial products. Non-standard structural parts can be categorized by their purpose and shape, such as mechanical fittings, pipe joints, and welded components.

[0003] During the welding process of non-standard structural parts, a positioning mechanism is required. Chinese utility model patent publication number CN211192720U discloses a positioning device for welding non-standard structural parts. The positioning device includes a workbench assembly, a rotating assembly, and a mounting seat. The mounting seats are provided with at least two fixedly mounted on the foundation. The rotating assemblies are provided with two rotating assemblies, each mounted on the mounting seat. The workbench assembly is mounted between the two rotating assemblies, and the rotating assembly drives the workbench assembly to flip. The positioning device also includes a positioning assembly, and the workbench assembly has a slot or hole that cooperates with the positioning assembly. This utility model has a cantilever ladle with a lid, a simple structure, and high welding efficiency.

[0004] However, during use, the utility model has the problem that the rotating assembly can only flip the non-standard structural parts in the front-to-back direction, but cannot drive the non-standard structural parts to rotate left-to-right. As a result, when the workers are welding the non-standard structural parts, they cannot make all-round adjustments according to actual needs, which affects the welding efficiency and cannot meet the production needs. Therefore, a positioning mechanism for welding non-standard structural parts is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a positioning mechanism for welding non-standard structural parts, which has the advantage of being able to drive the non-standard structural parts to rotate horizontally. It solves the problem that the rotating assembly can only flip the non-standard structural parts in the front-to-back direction, but cannot drive the non-standard structural parts to rotate left-to-right, making it impossible for workers to make all-round adjustments to the non-standard structural parts according to actual needs when welding them, affecting the welding efficiency and failing to meet production needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a positioning mechanism for welding non-standard structural parts, comprising a base and a first support column fixedly connected to the top of the base, a second support column fixedly connected to the side of the top of the base away from the first support column, and a horizontal rotation mechanism for horizontally rotating the non-standard structural parts provided between the first support column and the second support column;

[0007] The horizontal rotation mechanism includes a rotating plate rotatably connected to the opposite sides of the first support column and the second support column, a rotating table is fixedly installed between the two rotating plates, a driving motor is fixedly installed on the side of the rotating table close to the base, and a placing table extending to the top of the rotating table is fixedly connected to the output shaft of the driving motor.

[0008] Furthermore, a positioning slider extending into the interior of the placement table is fixedly connected to one side of the placement table close to the rotating table, and a positioning slot adapted to the positioning slider is provided on the upper surface of the rotating table.

[0009] Furthermore, a mounting plate is fixedly connected to a side of the placement table away from the rotating table, an electric push rod is fixedly installed on one side of the mounting plate, and a clamping plate is fixedly connected to the output end of the electric push rod.

[0010] Furthermore, the number of the mounting plates is four, and the four mounting plates are symmetrically distributed on the front, back, left and right sides of the top of the placement table.

[0011] Furthermore, a servo motor is fixedly installed on the side of the second support column close to the first support column, and a first pulley extending to the interior of the second support column is fixedly connected to the output shaft of the servo motor. A second pulley is provided on the side of the second support column away from the first pulley, and a transmission belt is connected between the first pulley and the second pulley.

[0012] Furthermore, one side of the right rotating plate is fixedly connected to a rotating shaft extending into the interior of the second supporting column, and the second pulley is fixedly connected to the exterior of the rotating shaft.

[0013] Furthermore, the two rotating plates are fixedly connected to a limit block extending into the first support column and the second support column on one side thereof, and the first support column and the second support column are provided with a limit groove adapted to the limit block on the opposite side thereof.

[0014] Compared with the prior art, the present invention provides a positioning mechanism for welding non-standard structural parts, which has the following beneficial effects:

[0015] 1. The alignment mechanism for welding non-standard structural parts is equipped with two rotating plates and a rotating table, so that the rotating table can drive the rotating table to rotate longitudinally, and then the placement table is driven to rotate by a driving motor. At this time, the staff places the non-standard structural parts on the placement table, and then the placement table can drive the non-standard structural parts to rotate horizontally, which is convenient for welding different positions on the non-standard structural parts and improves the scope of use.

[0016] 2. The alignment mechanism for welding non-standard structural parts is configured to drive the first pulley to rotate by setting a servo motor, and then the first pulley can simultaneously drive the transmission belt and the second pulley to rotate, so that the rotating plate can simultaneously drive the rotating table to rotate, and then can drive the non-standard structural parts to flip longitudinally, thereby improving welding efficiency. It solves the problem that the rotating assembly can only flip the non-standard structural parts in the front and back directions, and cannot drive the non-standard structural parts to rotate left and right, making it impossible for workers to fully adjust the non-standard structural parts according to actual needs when welding them, affecting welding efficiency and failing to meet production needs.
