DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] A frame flip arc welding fixture, comprising:

[0023] A horizontal rotation mechanism 1, a support frame 2 is provided on the upper end of the horizontal rotation mechanism 1, and a longitudinal rotation mechanism 3 is provided on the upper end of the support frame 2;

[0024] The lateral rotation mechanism 1 includes a base 11, in which a first driving motor 12 is installed. The output end of the first driving motor 12 is connected to a bevel gear set 13. The upper end of the driven wheel of the bevel gear set 13 is connected to a drive shaft 14. The upper end of the drive shaft 14 is connected to a lateral rotating seat 15 that is clamped and rotated on the upper end of the base 11.

[0025] The entire structure can be supported by the provided base 11, and adjustment feet can also be provided at the four corners so that it can be adjusted to a horizontal state before use, so that it can be more accurate and stable during welding. The first driving machine 12 provided inside drives the bevel gear set 13 to drive the drive shaft 14 to rotate, so that the transverse rotating seat 15 is located at the upper end of the base 11 to rotate transversely, and can be adjusted transversely when welding of other positions of the frame is required, thereby improving the efficiency of welding.

[0026] As an improvement of the above technical solution, the bevel gear set 13 includes a driving wheel connected to the output end of the first driving machine 12, and a driven wheel connected to the lower end of the driving shaft 14. The lower end of the driven wheel is also provided with a support column for rotation, which can more conveniently drive the bevel gear set 13 through the first driving machine 12 to drive the driving shaft 14 to rotate, making the rotation adjustment more stable.

[0027] The support frame 2 includes a lifting cylinder 21 and a lifting column 22 which is sleeved inside the lifting cylinder 21 and lifted by a piston. The upper end of the lifting column 22 is connected to a support platform 23.

[0028] The height of the lifting column 22 can be adjusted by the provided lifting cylinder 21, so that the frame can be lifted after being clamped and fixed by the clamping structure of the longitudinal rotating mechanism 3, thereby avoiding scratching the lower end of the frame and causing damage to the frame during the longitudinal flip adjustment. In addition, the supporting platform 23 provided at the upper end can more stably install and fix the longitudinal rotating mechanism 3.

[0029] The longitudinal rotation mechanism 3 includes a second driving motor 31 mounted on the upper end of the support frame 2 on one side, and a limit bearing seat 32 mounted on the upper end of the support frame 2 on the other side. The output end of the second driving motor 31 is connected to a driving rotating shaft 33, and a driven rotating shaft 34 is clamped inside the limit bearing seat 32. A fixed clamping frame 35 is fixedly connected between the driving rotating shaft 33 and the driven rotating shaft 34. Limiting guide pillars 36 are fixedly installed on both sides of the fixed clamping frame 35. A movable clamping frame 37 is sleeved on the surface of the limiting guide pillar 36. A clamping adjustment driving motor 38 is also provided between the movable clamping frame 37 and the fixed clamping frame 35 on one side.

[0030] The second driving motor 31 drives the active rotating shaft 33, which can drive the fixed clamping frame 35 to perform longitudinal flipping after the frame is fixed, so as to facilitate welding of the lower end and side ends of the frame. At the same time, when flipping, the driven rotating shaft 34 at one end can be clamped in the limiting bearing seat 32 for rotation, so that the longitudinal flipping can be more stable and avoid falling during the flipping process. At the same time, the movable clamping frame 37 is adjusted by the clamping adjustment driving motor 38, and the limiting guide column 36 is used for limiting during the adjustment process, so that the movable clamping frame 37 can move between the fixed clamping frames 35 to meet the function of freely adjusting and fixing frames of different sizes.

[0031] As an improvement of the above technical solution, movable holes are opened at both ends of the movable clamping frame 37. The movable clamping frame 37 is connected to the surface of the limiting guide column 36 through the movable holes, which can limit the movable clamping frame 37 and avoid offset when clamping and fixing the frame, resulting in welding offset.

[0032] As an improvement of the above technical solution, the clamping and adjusting drive motor 38 adopts a telescopic drive motor, and a telescopic rod with a piston sleeved inside the telescopic drive motor. One end of the telescopic rod is connected to the movable clamping frame 37, which can more stably adjust the movable clamping frame 37 to meet the function of stably clamping frames of different sizes.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
