DETAILED DESCRIPTION
[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0027] Embodiment 1
[0028] A kind of welding equipment welding torch anti-collision protection mechanism, as shown in Figures 1-4 shown, including welding torch body 1, the inner side of welding torch body 1 is fixedly connected with welding torch pipe 4, the left side of welding torch pipe 4 is fixedly connected with connecting block 5 and is penetrated, connecting block 5 and the connecting place of welding torch pipe 4 are fixedly connected with sealing ring 6, connecting block 5 is used for welding torch pipe 4 can be stably located in the inner side of welding torch body 1;Still include protection assembly 2, for preventing the top end of welding torch body 1 from being damaged;Control part 3, for guaranteeing the stability of welding torch body 1 when welding torch body 1 is welded;Protection assembly 2 includes bellows 21, the end close to welding torch pipe 4 of bellows 21 is fixedly connected with the surface of welding torch pipe 4, the end away from welding torch pipe 4 of bellows 21 is fixedly connected with welding torch head 22, the inner side of connecting block 5 is penetrated with knob 25, the end away from connecting block 5 of knob 25 is rotatably connected with conical protective sleeve 28.
[0029] First, a rotating ring 26 is rotatably connected to the side surface of the knob 25 near the connecting block 5. Because the knob 25 and the rotating ring 26 are rotatably connected, it can be ensured that the knob 25 will not cause the rotating ring 26 to rotate together when it rotates, thus preventing the spring 27 from twisting and avoiding motion interference. The rotating ring 26 and the inner side of the connecting block 5 are fixedly connected to the spring 27. After the conical protective sleeve 28 no longer comes into contact with foreign objects or is blocked by obstacles, the spring 24 will push the telescopic rod 23 out of the welding gun tube 4, causing the telescopic rod 23 to push the welding gun head 22. At the same time, the compressed spring 27 will also push the knob 25 out of the connecting block 5 through the rotating ring 26.
[0030] It is worth noting that a spring 24 is fixedly connected to the end of the telescopic rod 23 away from the welding torch head 22, and the end of the spring 24 away from the telescopic rod 23 is fixedly connected to the inner wall of the welding torch tube 4. There are three sets of telescopic rods 23, and the three sets of telescopic rods 23 are arranged in a circular array with the center line of the welding torch head 22 as the axis. The three sets of telescopic rods 23 arranged in a circular array can make the welding torch head 22 retract stably and avoid jamming.
[0031] In this embodiment, when the inclined surface of the conical protective sleeve 28 is squeezed by an external force, it pushes the knob 25, causing the knob 25 to push the rotating ring 26. After the rotating ring 26 is pushed, it compresses the second spring 27. At the same time, after the knob 25 is pushed, the abutment rod 31 passing through the knob 25 is inserted into the guide groove 33, causing the abutment rod 31 to abut against the guide groove 33 and push the connecting sleeve 32. This further causes the connecting sleeve 32 to drive the welding gun head 22 to compress the bellows 21 and retract the welding gun head 22 into the connecting block 5. During the retraction process, the welding gun head 22 will cause the telescopic rod 23 to be inserted into the welding gun tube 4, and the telescopic rod 23 will compress the first spring 24. Thus, the conical protective sleeve 28 is first blocked by an external force, causing the welding gun head 22 to retract into the connecting block 5, avoiding damage to the welding gun head 22 from collision.
[0032] Example 2
[0033] like Figures 4-5 As shown, the control unit includes a connecting sleeve 32, through which the welding torch head 22 is fixedly connected. A guide groove 33 is provided on the surface of the connecting sleeve 32. An abutment rod 31 is provided through and fixedly connected to the inner side of the knob 25. The abutment rod 31 is inserted into the guide groove 33 on the surface of the connecting sleeve 32. When the knob 25 is rotated, it will drive the abutment rod 31 on its inner side to rotate together. The abutment rod 31 is inserted into the inner side of the guide groove 33. The guide groove 33 is opened around the connecting sleeve 32 and is arc-shaped, so that the abutment rod 31 gradually abuts against the guide groove 33 and forces the connecting sleeve 32 to gradually move to the outside of the connecting block 5.
[0034] First, the surface of the conical protective sleeve 28 is through and movably connected with the plug rod 34, the inner side of the plug rod 34 is fixedly connected with the spring three 35, and the bottom end of the spring three 35 is fixedly connected with the surface of the conical protective sleeve 28.
[0035] Secondly, the top surface of the welding gun head 22 is provided with a clamping groove 36, and the bottom surface of the plug rod 34 is an arc surface, in the process that the welding gun head 22 extends out of the conical protective sleeve 28, the welding gun head 22 will abut against the inclined surface of the plug rod 34 and lift the plug rod 34, so that the plug rod 34 stretches the spring three 35, and when the plug rod 34 is aligned with the clamping groove 36, the stretched spring three 35 will pull the plug rod 34 to insert the plug rod 34 into the clamping groove 36.
[0036] In the embodiment, in the process that the welding gun head 22 extends out of the conical protective sleeve 28, the welding gun head 22 will stretch the spring one 24, so that after the welding work is completed, the welding gun head 22 will be pulled back into the conical protective sleeve 28 and be protected from collision, and in the process that the welding gun head 22 extends out of the conical protective sleeve 28, the welding gun head 22 will abut against the inclined surface of the plug rod 34 and lift the plug rod 34, so that the plug rod 34 stretches the spring three 35, and when the plug rod 34 is aligned with the clamping groove 36, the stretched spring three 35 will pull the plug rod 34 to insert the plug rod 34 into the clamping groove 36, so that the welding gun head 22 can stably perform the welding work.
[0037] The welding equipment welding gun anti-collision protection mechanism of the utility model in use, before the welding gun body 1 is used, if the staff accidentally hits the front end of the welding gun body 1 to the object to be welded or other obstacles, first will touch the conical protective sleeve 28, and the inclined surface of the conical protective sleeve 28 is extruded by external force and will push the knob 25, so that the knob 25 pushes the rotating ring 26, and the rotating ring 26 is compressed after being pushed by the force, and at the same time, after the knob 25 is pushed, the abutting rod 31 through the knob 25 is inserted into the guide groove 33, so that the abutting rod 31 abuts against the guide groove 33 and pushes the connecting sleeve 32, further makes the connecting sleeve 32 drive the welding gun head 22 and compresses the corrugated pipe 21, and makes the welding gun head 22 retract into the connecting block 5, and the telescopic rod 23 will be inserted into the welding gun tube 4 in the process of retraction, and the telescopic rod 23 will compress the spring one 24, so that the conical protective sleeve 28 is first blocked by the force of external force and drives the welding gun head 22 to retract into the connecting block 5, avoiding the damage of the welding gun head 22 caused by collision, and after the conical protective sleeve 28 no longer abuts against the external object or is blocked by the obstacle, the spring one 24 will push the telescopic rod 23 from the welding gun tube 4, so that the telescopic rod 23 pushes the welding gun head 22, and the compressed spring two 27 will also push the knob 25 out of the connecting block 5 through the rotating ring 26.
[0038] When the welding work needs to be carried out, the knob 25 can be rotated, and since the knob 25 is rotationally connected with the rotating ring 26, the knob 25 can be ensured not to rotate the rotating ring 26 together to twist the second spring 27, thereby avoiding motion interference. When the knob 25 is rotated, the knob 25 can drive the abutting rod 31 inside the knob 25 to rotate, and the abutting rod 31 is inserted into the inside of the guide groove 33, and the guide groove 33 is arranged around the connecting sleeve 32 and is arc-shaped, so that the abutting rod 31 gradually abuts against the guide groove 33 to force the connecting sleeve 32 to gradually move to the outside of the connecting block 5, and the connecting sleeve 32 drives the welding torch head 22 fixedly connected to the inside of the connecting sleeve 32 to extend out of the conical protective sleeve 28. When the welding torch head 22 extends out of the conical protective sleeve 28, the welding torch head 22 is stretched by the first spring 24, so that after the welding work is completed, the welding torch head 22 is pulled back into the conical protective sleeve 28 to be protected from collision. In the process of extending the welding torch head 22 out of the conical protective sleeve 28, the welding torch head 22 abuts against the inclined surface of the insertion rod 34 to lift the insertion rod 34, so that the insertion rod 34 stretches the third spring 35. When the insertion rod 34 is aligned with the clamping groove 36, the stretched third spring 35 pulls the insertion rod 34 to insert the insertion rod 34 into the clamping groove 36, so that the welding torch head 22 can stably carry out the welding work. After the welding work is completed, the insertion rod 34 is lifted, so that the insertion rod 34 no longer limits the welding torch head 22, so that the stretched third spring 35 can pull back the welding torch head 22.
