Description

Technical Field

[0001] The utility model belongs to the technical field of welding tooling, and in particular relates to a welding tooling which can be rotatably positioned. Background Art

[0002] At present, in actual production operations, it is necessary to fully weld two pre-welded left and right brackets on the chassis with argon arc welding. Since the chassis weighs about 30KG, there are two traditional welding methods. One method is to place the chassis flat on a workbench, and the welder welds around the workbench; the other method is to place the chassis on a rotating workbench. When welding is required, the worker rotates the workbench and then welds the chassis.

[0003] However, the first welding method has the disadvantages of high labor intensity, slow speed, low efficiency, and difficulty in ensuring quality. The second welding method does not have a fixed structure on the workbench. When the workbench is rotated, the chassis placed on it may shift, which may cause the chassis to be unable to be welded smoothly and with high quality. Therefore, a rotatable and positionable welding tool is needed to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a driving assembly, a turntable, a clamping assembly, an adjusting assembly and a resetting assembly. When the chassis is placed between two clamping plates, the operating rod is rotated forward, and the two clamping plates close to each other drive the protective pads to contact the chassis and then lower and fix them on the turntable.

When the operating rod is turned reversely, the two clamping plates can drive the protective pads to move closer to each other, thereby clamping and fixing chassis of different sizes, thereby improving the applicability of the tooling.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] See also Figure 1-5 The utility model provides a rotatable and positionable welding tool, including a support platform 1, a driving component 2, a workbench 3, an adjusting component 4, two resetting components 5 and two clamping components 6. The lower surface of the support platform 1 is connected to the protective shell 7. The driving component 2 includes a motor 21, a worm 22, a worm wheel 23 and a rotating rod 24. The output shaft of the motor 21 is connected to the worm 22. The motor 21 is clamped on the back of the protective shell 7. The worm 22 is rotatably connected in the protective shell 7. The worm 22 is meshed with the worm wheel 23. The worm 22 and the worm wheel 23 are both arranged in the protective shell 7. The worm wheel 23 is clamped on the outside of the rotating rod 24. The rotating rod 2 The workbench 3 is rotatably connected in the support platform 1, and includes a turntable 31. A first piston cavity 32, two connecting holes 33, two second piston cavities 34 and two limiting grooves 35 are provided in the turntable 31. The lower surface of the turntable 31 is connected to the top of the rotating rod 24. By providing the worm 22 and the worm wheel 23, the rotating worm 22 can not only drive the turntable 31 to rotate through the worm wheel 23 and the rotating rod 24, but also when the motor 21 stops working, the worm 22 and the worm 22 can also use their own self-locking function to lock the turntable 31 through the rotating rod 24, so that the turntable 31 is not easy to rotate under the action of external force;

[0023] The adjustment assembly 4 includes an operating rod 41, a threaded rod 42, a threaded barrel 43 and a piston plate 44. The operating rod 41 is rotatably connected to the turntable 31. One end of the operating rod 41 is connected to the threaded rod 42. The threaded rod 42 is threadedly connected to the threaded barrel 43. One end of the threaded barrel 43 is connected to the piston plate 44. The piston plate 44 is slidably connected to the first piston chamber 32. By arranging the threaded rod 42 and the threaded barrel 43, the rotating threaded rod 42 can drive the piston plate 44 to move in the first piston chamber 32 through the threaded barrel 43.

[0024] The reset assembly 5 includes a piston rod 51, a limit block 52 and a spring 53. The piston rod 51 is slidably connected in the second piston chamber 34. The first piston chamber 32 is connected to the two second piston chambers 34 through two connecting holes 33 respectively. The ends of the two piston rods 51 that are away from each other are connected to the limit blocks 52. The piston rod 51 is sleeved in the spring 53. The two ends of the spring 53 are respectively connected to the limit groove 35 and the limit block 52. The limit block 52 is slidably connected in the limit groove 35. The shape of the limit block 52 is set to be rectangular. By setting the limit block 52 and the limit groove 35, because the limit block 52 is slidably connected in the limit groove 35, the limit groove 35 can limit the limit block 52, so that the limit block 52 will not shake during movement, so that the moving piston rod 51 can drive the clamping plate 61 to move smoothly along the axial direction of the piston rod 51 through the limit block 52;

[0025] The clamping assembly 6 includes a clamping plate 61 and a protective pad 62. The lower surface of the clamping plate 61 is connected to the limit block 52, and the adjacent sides of the two clamping plates 61 are connected to the protective pad 62. The operating rod 41 is arranged just in front of the middle part of the two clamping plates 61. By setting the protective pad 62, the protective pad 62 can separate the clamping plate 61 from the chassis, so that the two clamping plates 61 adjacent to each other are not easily in direct contact with the chassis and thus damage the outer surface thereof.

[0026] The working principle and use process of the utility model are as follows: when the tooling needs to be used, the operating rod 41 is rotated forward, and the rotating operating rod 41 drives the threaded rod 42 to rotate. The threaded cylinder 43 drives the piston plate 44 to move backward in the first piston chamber 32 under the action of the forward rotating threaded rod 42. At this time, the first piston chamber 32, the connecting hole 33 and the two second piston chambers 34 are all in a positive pressure state. At this time, the two piston rods 51 in the two second piston chambers 34 are away from each other, and the chassis is placed between the two clamping plates 61. The operating rod 41 is rotated forward, and the two clamping plates 61 approaching each other drive the protective pads 62 to approach each other, and then contact with both sides of the chassis. At this time, the chassis can be fixed on the turntable 31;

[0027] The control motor 21 works, and the working motor 21 drives the worm 22 to rotate in the protective shell 7. The rotating worm 22 drives the worm wheel 23 to rotate. The rotating worm wheel 23 drives the rotating rod 24 to rotate in the support platform 1. The rotating rotating rod 24 drives the turntable 31 to rotate. The rotating turntable 31 can drive the chassis placed on its surface to rotate. When the chassis rotates to a suitable welding position, the control motor 21 stops working, and the chassis can be welded at this time.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
