Detailed Description

The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.

For ease of understanding, the welded leg rest of the swivel chair will now be described. Referring to fig. 1, the leg rest includes a middle tube 8, a first connecting tube 81 and a second connecting tube 82 welded on the middle tube 8, and a leg rest tube 83 welded on an end of the first connecting tube 81 and the second connecting tube 82 facing away from the middle tube 8. In whole welding process, use spot welding earlier with first connecting pipe 81 and second connecting pipe 82 weld on well pipe 8, then use the anchor clamps of this application to carry out reinforcement welding to first connecting pipe 81 and second connecting pipe 82 again for it is more firm between first connecting pipe 81 and second connecting pipe 82 and well pipe 8.

The embodiment of the application discloses swivel chair is anchor clamps for welding. Referring to fig. 2 and 3, a swivel chair welding jig includes a table 1. The rotary worktable is provided with a base 2 on the worktable 1, the two ends of the base 2 are respectively provided with a first limiting block 31 and a second limiting block 32 in a sliding manner, the first limiting block 31 and the second limiting block 32 are respectively positioned at the two sides of the rotary shaft of the base 2, and a space for placing the middle pipe 8 is formed between the first limiting block 31 and the second limiting block 32. A first adjusting component for adjusting the position of the first stopper 31 on the base 2 is arranged on the base 2. A second adjusting component for adjusting the position of the second limiting block 32 on the base 2 is arranged on the base 2. A clamping assembly for fixing the middle tube 8 is arranged on the base 2.

Referring to fig. 2 and 3, before welding, the positions of the first stopper 31 and the second stopper 32 are adjusted. During the welding, when well pipe 8 supported on first stopper 31, the axis of first connecting pipe 81 coincides mutually with the axis of rotation of base 2 for staff is when rotating base 2, and first connecting pipe 81 only can take place to rotate, and the position of first connecting pipe 81 can not change, has made things convenient for the staff to weld along the circumferential surface of first connecting pipe 81. When the middle pipe 8 abuts against the second limiting block 32, the axis of the second connecting pipe 82 coincides with the axis of the rotating shaft of the base 2, and therefore the second connecting pipe 82 can be conveniently welded by workers. When the welding, the centre gripping subassembly can be fixed well pipe 8 for well pipe 8 is more firm when the welding, has promoted the welding effect.

Referring to fig. 2 and 3, in order to facilitate a worker to observe whether the first connection pipe 81 and the second connection pipe 82 are aligned with the rotation axis of the base 2, a mark block 4 is fixedly provided on the upper surface of the base 2. The marking block 4 is aligned with the rotating shaft of the base 2, so that the staff can observe the mark more visually and conveniently.

Referring to fig. 4, the base 2 is provided with a first sliding slot 21 with two closed ends, and the first stopper 31 is fixedly provided with a first sliding block 311. The first sliding block 311 is slidably disposed in the first sliding groove 21, so that the first stopper 31 is more stable when moving on the base 2, and is not prone to being inclined.

Referring to fig. 4, the base 2 is provided with a second sliding groove 22 with two closed ends, and the second limiting block 32 is fixedly provided with a second sliding block 321. The second sliding block 321 is slidably disposed in the second sliding groove 22, so that the second limiting block 32 is more stable when moving on the base 2, and is not prone to being inclined.

Wherein, the first sliding chute 21 and the second sliding chute 22 are respectively positioned at two sides of the rotating shaft of the base 2. The first runner 21 and the second runner 22 are dovetail grooves. The first slider 311 is provided as a trapezoidal block to be matched with the first slide groove 21, and the second slider 321 is provided as a trapezoidal block to be matched with the second slide groove 22. By arranging the first sliding groove 21 and the second sliding groove 22 as dovetail grooves, the stability of the first slider 311 and the second slider 321 on the base 2 can be improved, so that the first stopper 31 and the second stopper 32 are more firmly fixed on the base 2.

Referring to fig. 4, the first adjusting assembly includes a first screw 51 rotatably disposed on the base 2 and a first knob 52 fixedly disposed at an end of the first screw 51 far away from the second limiting block 32. The axial direction of the first screw 51 is the same as the groove length direction of the first slide groove 21. The first screw 51 is in threaded connection with the first slider 311, and the worker can make the first slider 311 drive the first stopper 31 to move on the base 2 by rotating the first knob 52.

Referring to fig. 4, the second adjusting assembly includes a second screw 61 rotatably disposed on the base 2 and a second knob 62 fixedly disposed at an end of the second screw 61 away from the first stopper 31. The axial direction of the second screw 61 is the same as the groove length direction of the second slide groove 22. The second screw 61 is in threaded connection with the second sliding block 321, so that when the worker rotates the second knob 62, the second screw 61 drives the second sliding block 321, and the second sliding block 321 drives the second limiting block 32 to move.

Referring to fig. 2 and 3, the clamping assembly includes clamping blocks 71 hinged to both sides of the base 2 and a spring plate 72 for urging the two clamping blocks 71 to rotate toward each other. One end of the spring piece 72 is fixedly connected to the base 2, and the other end of the spring piece 72 abuts against the holding block 71. The spring piece 72 is always in a deformed state, and can continuously apply an acting force to the two clamping blocks 71, so that the two clamping blocks 71 rotate in a direction of approaching each other, and a gap for clamping the middle pipe 8 is formed between the two clamping blocks 71.

Referring to fig. 2 and 3, in order to further improve the stability of the middle tube 8, the side of the two clamping blocks 71 close to each other is set to be an arc-shaped surface matched with the middle tube 8, so that the clamping blocks 71 can be attached to the outer wall of the middle tube 8.

The implementation principle of the embodiment of the application is as follows: before the welding, adjust the position of first stopper 31 and second stopper 32 to well pipe 8 of different length for when well pipe 8 supports on first stopper 31, the axis of first connecting pipe 81 coincides with the axis of rotation of base 2, and when well pipe 8 supported on second stopper 32, the axis of second connecting pipe 82 coincides with the axis of rotation of base 2.

The two clamping blocks 71 are opened, the middle pipe 8 is placed on the base 2, and the middle pipe 8 is clamped and fixed by the two clamping blocks 71. When welding, through rotating base 2, weld the circumferential connection face of first connecting pipe 81 or second connecting pipe 82, welding process is more convenient, has reduced the operation degree of difficulty.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
