[0027] As a technical optimization scheme of the utility model, the components can be preliminarily positioned by placing the groove 3, and the inner cavity of the movable block 6 is provided with an internal thread used in conjunction with the screw rod 5. When the first motor 4 drives the screw rod 5 to rotate, the movable block 6 will drive the movable rod 7 and the clamping block 8 to move in turn, thereby stably clamping the components from all sides, and the fixing force can be evenly applied by fixing in four directions, making the components more stable during the welding process.

[0028] The rotating mechanism includes a second motor 10 buried in the bottom of the mounting plate 2, the output shaft of the second motor 10 is fixedly connected to the first rotating shaft through a coupling, the top flat key of the first rotating shaft is connected to a driving gear 11, one side of the driving gear 11 is meshed with a driven gear 12, the top flat key of the driven gear 12 is connected to a second rotating shaft 13, the second rotating shaft 13 is fixedly connected to the bottom of the workbench 1 by bolts, and limiting mechanisms are arranged around the bottom of the workbench 1.

[0029] As a technical optimization solution of the utility model, the cooperation of the driving gear 11 and the driven gear 12 can enable the workbench 1 to drive the components to rotate, thereby avoiding the operator from over-stretching the body or twisting the posture to adjust the welding angle, thereby reducing the risk of operation and possible injury. At the same time, the automatic rotation tooling can quickly and accurately adjust the welding angle, saving the time and labor cost of manual adjustment.

[0030] The limiting mechanism includes a limiting groove 14 formed on the top of the mounting plate 2 . The inner cavity of the limiting groove 14 is slidably connected to a limiting block 15 . The limiting blocks 15 are fixedly connected to the bottom of the workbench 1 around by bolts.

[0031] As a technical optimization solution of the present invention, the cooperation between the limiting groove 14 and the limiting block 15 can play the role of limiting and supporting the workbench 1.

[0034] Integrally formed support frames 17 are provided on both sides of the bottom of the mounting plate 2. The support frame 17 and the mounting plate 2 are both integrated structures formed by welding steel materials.

[0035] As a technical optimization solution of the utility model, the steel material forms a whole after welding, so the rigidity is better and the reliability is higher.

[0036] Working principle: The user places the components on the top of the placement slot 3, and then drives the lead screw 5 to rotate through the first motor 4, so that the movable block 6 drives the movable rod 7 and the clamping block 8 to move, and then uses the clamping block 8 to position the components from all sides. Compared with the traditional positioning on both sides, clamping the components from all sides can provide more support and fixing points, so as to fix the components more firmly, reduce movement or shaking during welding, and ensure the accuracy and consistency of welding. The second motor 10 drives the driving gear 11, the driven gear 12, the second rotating shaft 13 and the workbench 1 to rotate in turn, so as to adjust the direction of the components and thus adjust the welding angle. Compared with the manual rotation tooling, the automatic rotation tooling reduces the difficulty and technical requirements of the operation, and can save the time and labor costs of manual adjustment.

[0037] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
