DETAILED DESCRIPTION

[0027] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

A limit assembly 2 is provided on the base 1 for limiting the rotation of the rotating seat 11. A driving assembly 3 for controlling the rotation of the clamping jaw 12 is provided on the rotating seat 11. The clamping jaw 12 is used to clamp the pipe workpiece to be welded, and the driving assembly 3 realizes the automatic rotation of the pipe workpiece by driving the clamping jaw 12 to rotate.

[0030] The driving assembly 3 includes a toothed disc 31 fixedly connected to the clamping jaw 12, and the central axis of the toothed disc 31 is colinear with the rotation axis of the clamping jaw 12 on the rotating seat 11. The rotating seat 11 is provided with a groove 32 for accommodating the toothed disc 31, and a motor 33 is fixedly connected to the rotating seat 11. The motor 33 is located on the side of the rotating seat 11 away from the clamping jaw 12. The output shaft of the motor 33 extends into the groove 32, and a driving gear 34 is fixedly connected to the output shaft of the motor 33, and the driving gear 34 is meshed with the toothed disc 31. When the motor 33 is working, its output shaft drives the driving gear 34 to rotate, thereby driving the toothed disc 31 and the clamping jaw 12 to rotate synchronously, so as to realize the rotation of the pipeline workpiece around its own axis.

[0031] The limiting assembly 2 includes a worm wheel 21 and a worm 22 that mesh with each other. A rotating shaft is fixedly connected to both sides of the rotating seat 11, and the axis of the rotating shaft is perpendicular to the rotation axis of the clamp 12 on the rotating seat 11. The rotating seat 11 is rotatably connected to the base 1 through the rotating shaft. The worm wheel 21 is coaxially fixedly connected to one of the rotating shafts, and the worm 22 is rotatably connected to the base 1, and can be rotated manually or electrically, thereby driving the worm wheel 21 to rotate and thus driving the rotating seat 11 to flip. By adjusting the position or angle of the worm 22, the rotation of the rotating seat 11 can be precisely controlled, thereby adjusting the welding angle of the pipeline workpiece.

[0032] The implementation principle of the embodiment of the present invention is as follows: the base 1 is used to support and stabilize the entire tooling, and a clamping jaw 12 is rotatably connected thereto, and the clamping jaw 12 is used to clamp the workpiece to be welded. A driving assembly 3 is provided on the base 1, and the driving assembly 3 is connected to the clamping jaw 12, and is used to control the rotation of the clamping jaw 12, thereby driving the workpiece to rotate, so that the welding gun can be stationary and complete the circumferential surface welding of the workpiece.

[0033] Example 2

[0034] like Figure 3 and Figure 4As shown, the difference between this embodiment and embodiment 1 is that the clamping jaw 12 includes a connecting seat 4 and a three-jaw chuck disposed on the connecting seat 4. The connecting seat 4 is rotatably connected to the rotating seat 11, and a plurality of connecting rods 41 are hinged on the three-jaw chuck, and the plurality of connecting rods 41 are evenly arranged around the rotation axis of the three-jaw chuck. A slider 42 is hinged on one end of the connecting rod 41 away from the three-jaw chuck, and the slider 42 is slidably disposed on the connecting seat 4, and the sliding direction is parallel to the radial direction of the connecting seat 4. A control component 5 is disposed on the connecting seat 4, which is used to control the sliders 42 to approach or move away from each other, so that the three-jaw chuck approaches or moves away from the connecting seat 4.

[0035] like Figure 5 and Figure 6 As shown, the control assembly 5 includes a rotating disk 51 rotatably connected to the connecting seat 4, and the rotating disk 51 is annular, and the central axis of the rotating disk 51 is colinear with the rotation axis of the connecting seat 4 on the rotating seat 11. The rotating disk 51 is provided with guide grooves 52 corresponding to the positions of each slider 42, and the slider 42 is provided with a support rod 53 for inserting into the guide groove 52. When the rotating disk 51 rotates, the guide groove 52 can push the slider 42 to slide along the radial direction of the connecting seat 4. In addition, the rotating disk 51 is coaxially provided with an annular driven bevel gear 55, and the rotating disk 51 is rotatably connected with a plurality of driving bevel gears 54, and the plurality of driving bevel gears 54 are arranged at intervals in the circumferential direction of the driven bevel gear 55. The driving bevel gear 54 is meshed with the driven bevel gear 55, and the rotating disk 51 and the slider 42 can be driven to move synchronously by driving the driving bevel gear 54 to rotate.

[0036] Example 3

The support frame 6 includes a base plate 61 fixedly connected to the base 1, and a pair of support frames 67 are hinged on the base plate 61. The pair of support frames 67 is provided with two and are symmetrically arranged along the hinge axis of the rotating seat 11. Support arms 62 are hinged on the two support frames 67, and a movable seat 63 is hinged on one end of the two support arms 62 away from the support frames 67. Rollers 64 for supporting the workpiece are rotatably connected to the two support frames 67. A stud 65 is rotatably connected to the base plate 61, and the axial direction of the stud 65 is parallel to the hinge axis of the rotating seat 11. The stud 65 passes through the two movable seats 63 and is threadedly connected to the two movable seats 63. The threaded sections of the two movable seats 63 corresponding to the stud bolts 65 rotate in opposite directions. When the stud bolts 65 are rotated, the two movable seats 63 can be moved closer to or farther from each other, thereby adjusting the position and angle of the roller 64 to adapt to pipe workpieces of different sizes.

[0038] The rollers 64 correspond to the support frames 67 one by one, and the rollers 64 are rotatably connected to the corresponding support frames 67. The central axes of the two rollers 64 intersect to form a limiting groove 66 for supporting the pipe workpiece, so as to ensure the stability of the pipe workpiece during rotation.
