[0002] At present, domestic welding tooling has become more mature. The tooling mainly has two structural forms: rigid and flexible. The design and manufacturing cycle of rigid tooling is long, and it can only be used for special purposes and cannot meet the needs of flexible manufacturing. Flexible tooling overcomes the above-mentioned shortcomings of rigid tooling and has become an important trend in the development of tooling technology today.

The utility model not only ensures the accuracy of the tooling when in use, improves the scope of application of the tooling, but also improves the stability of the tooling when in use.

[0004] However, the above-mentioned prior art still has shortcomings when in use: although the platform tooling has the functions of expansion, anti-slip and position adjustment, its convenience during welding is poor, that is, the operator needs to move the position during welding to fully weld, which has the disadvantage of poor convenience of welding operation.

[0005] To this end, the utility model provides a three-dimensional flexible welding processing platform. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a three-dimensional flexible welding processing platform to solve the problems raised in the above-mentioned background technology. The processing platform of the utility model has the functions of self-rotation and revolution, which is convenient for driving the workpiece to be in a more reasonable welding position, greatly reducing the labor intensity of welding for operators, and the revolution and self-rotation control of the processing platform is more convenient.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a three-dimensional flexible welding processing platform, including a base plate, the top of the base plate is rotatably connected to a support column, the top of the support column is rotatably connected to a welding platform, the welding platform and the base plate are parallel, the support column is parallel to the rotation axis of the base plate and the welding platform, a lower rotation control structure is provided at the rotation connection between the support column and the base plate, and an upper rotation control structure is provided at the rotation connection between the support column and the welding platform.

The opposite sides of the base plate and the welding platform are bolted with lower and upper limit sleeves that are rotatably connected to the lower and upper truncated cones, respectively.

[0009] Furthermore, the lower rotation control structure includes a control motor, a control gear and a transmission gear. The transmission gear is fixedly sleeved on the lower short-circuit shaft. The control motor is fixedly arranged on the bottom plate and its output shaft is fixedly connected to the control gear. The control gear and the transmission gear are meshed.

[0010] Furthermore, the upper rotation control structure includes a worm and a worm wheel, the worm is rotatably connected to one side of the upper limit sleeve, and the worm wheel fixed sleeve is arranged on the upper short-circuit shaft and meshes with the worm.

[0011] Furthermore, the upper rotation control structure also includes a bevel gear ring rotatably connected below the welding platform, and a bevel gear meshing with the bevel gear ring is welded to one end of the worm.

[0012] Furthermore, a plurality of circumferentially distributed handle bars are welded to the outer peripheral wall of the bevel gear ring.

[0013] Furthermore, a plurality of welding clearance gaps are provided on the welding platform.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model connects an inclined support column between the base and the welding platform by rotation, so that the welding platform has the function of self-rotation relative to the support column and the function of revolution relative to the base. The self-rotation and revolution of the welding platform facilitate switching of the welding position on the workpiece, so that the welding position can be in a state that is more friendly to manual welding operation.

[0016] 2. The utility model provides an upper rotation control structure for controlling the rotation of the welding platform and a lower rotation control structure for controlling the revolution of the welding platform relative to the base plate at both ends of the support column, thereby making it more convenient to adjust the revolution and rotation of the welding platform.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a three-dimensional flexible welding processing platform, including a bottom plate 1, the bottom plate 1 is disc-shaped, the top of the bottom plate 1 is rotatably connected to a support column 2, the top of the support column 2 is rotatably connected to a welding platform 3, and the specific implementation structure is that the support column 2 is tilted and welded with parallel upper short-circuit shafts 21 and lower short-circuit shafts 22 at both ends, the top of the upper short-circuit shaft 21 is welded with an upper circular table 211, and the bottom of the lower short-circuit shaft 22 is welded with a lower circular table 221. The bottom of the bottom plate 1 and the welding platform 3 are connected by bolts on the opposite sides with a lower limit sleeve 11 and an upper limit sleeve 31 that are rotatably connected to the lower circular table 221 and the upper circular table 211 respectively. The welding platform 3 is used to support welding tooling. The welding platform 3 is parallel to the bottom plate 1, and the expansion of the welding platform 3 and the structure for shifting the tooling both adopt the structure of the prior art mentioned in the background technology. This application does not improve the structure of the above-mentioned prior art. The support column 2 is parallel to the rotation axis of the base plate 1 and the welding platform 3. This arrangement enables the welding platform 3 to have the function of self-rotation and the function of revolution relative to the base plate 1.

[0023] A lower rotation control structure 4 is provided at the rotation connection between the support column 2 and the bottom plate 1 . The function of the lower rotation control structure 4 is to control the rotation of the support column 2 relative to the bottom plate 1 .

[0024] Specifically, the lower rotation control structure 4 includes a control motor 41, a control gear 42 and a transmission gear 43. The transmission gear 43 is fixedly mounted on the lower short-circuit shaft 22. The control motor 41 is fixedly arranged on the base plate 1 and its output shaft is fixedly connected to the control gear 42. The control gear 42 and the transmission gear 43 are meshed. The control motor 41 controls the rotation of the support column 2 relative to the base plate 1 through the meshing of the control gear 42 and the transmission gear 43.

[0025] An upper rotation control structure 5 is provided at the rotation connection between the support column 2 and the welding platform 3 . The upper rotation control structure 5 is used to control the welding platform 3 to rotate relative to the support column 2 .

[0026] Specifically, the upper rotation control structure 5 includes a worm 51 and a worm wheel 52. The worm 51 is rotatably connected to one side of the upper limit sleeve 31. During implementation, a support is welded to the outer peripheral wall of the upper limit sleeve 31. The support is rotatably connected to the worm 51. The worm wheel 52 is fixedly sleeved on the upper short-circuit shaft 21 and meshes with the worm 51. When the worm 51 is controlled to rotate, the worm wheel 52 is driven to rotate, and the entire welding platform 3 will rotate relative to the support column 2.

[0027] In this embodiment, the upper rotation control structure 5 also includes a bevel gear ring 53 rotatably connected to the bottom of the welding platform 3. During implementation, a positioning sleeve can be welded under the welding platform 3. The positioning sleeve and the bevel gear ring 53 are sleeved and rotationally matched. A bevel gear 511 meshing with the bevel gear ring 53 is welded at one end of the worm 51. When the bevel gear ring 53 rotates, it will drive the worm 51 to rotate, which is convenient for controlling the rotation of the welding platform 3 at any position.

[0028] Furthermore, a plurality of circumferentially distributed handles 531 are welded to the outer peripheral wall of the bevel gear ring 53 . The handles 531 are components for manually holding and controlling the rotation of the bevel gear ring 53 .

[0029] In this embodiment, a plurality of welding clearance gaps 32 are provided on the welding platform 3 . The advantage of this arrangement is that it is convenient for welders to perform overhead welding on the workpiece through the welding clearance gaps 32 .

[0030] Working principle: The tooling is installed on the welding platform 3 by bolts, and then the workpiece is fastened to the welding platform 3 by the tooling. When the welding position needs to be switched, the handle 531 is manually held to drive the bevel gear ring 53 to rotate. The rotation of the worm 51 causes the entire welding platform 3 to rotate relative to the support column 2 due to the limiting effect of the worm wheel 52, and the welding position on the workpiece is moved in front of the operator. When the welding position is not close enough to the welder after the workpiece is moved, the control motor 41 is started, and the support column 2 is driven to rotate through the cooperation of the control gear 42 and the transmission gear 43. At this time, the entire welding platform 3 is in a state of revolution, and then the position of the workpiece can be adjusted by the handle 531.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
