Therefore, the staff is required to replace the conductive nozzle regularly. The existing replacement process of the conductive nozzle is generally: cut off the welding wire head, then disassemble the nozzle, clean the nozzle, then disassemble the old conductive nozzle, install the new conductive nozzle, and finally install the cleaned nozzle. The existing process of replacing the conductive nozzle is complicated and time-consuming.
[0003] In view of this, it is necessary to provide a new workpiece changing sleeve and a workpiece changing tool to solve or at least alleviate the above-mentioned technical defects. Utility Model Content

[0026] Furthermore, the technical solutions between the various implementation modes of the present invention can be combined with each other, but this must be based on the fact that ordinary technicians in the field can implement them.

[0027] The utility model provides a workpiece replacement sleeve 1 for replacing a conductive nozzle. In one embodiment, Figure 1 and Figure 2 As shown, the workpiece replacement sleeve 1 includes a main body 11 and a cleaning member 12. The main body 11 includes a first end 111 and a second end 112 that are relatively arranged. The first end 111 is used to extend into the nozzle from the opening end of the nozzle. The first end 111 is provided with a slot 113. The slot wall of the slot 113 is used to engage with the outer wall of the conductive nozzle so that the main body 11 can drive the conductive nozzle to rotate; the cleaning member 12 is arranged on the outer wall of the main body 11, and when the slot 113 is engaged with the conductive nozzle, the cleaning member 12 can abut against the inner wall of the nozzle; the main body 11 can drive the cleaning member 12 to rotate relative to the nozzle, so that the cleaning member 12 can separate foreign matter located on the inner wall of the nozzle from the nozzle.
[0028] Among them, since the first end 111 of the body 11 can extend into the nozzle from the open end of the nozzle, and the slot 113 provided on the first end 111 can be engaged with the outer wall of the conductive nozzle, the user can drive the conductive nozzle to rotate through the body 11 without disassembling the nozzle, thereby completing the disassembly of the conductive nozzle, eliminating the process of disassembling and installing the nozzle, and saving the time spent on the entire process of replacing the conductive nozzle; and since the outer wall of the body 11 is also provided with a cleaning member 12, when the slot 113 is engaged with the conductive nozzle, the cleaning member 12 abuts against the inner wall of the nozzle, and the body 11 is rotated to drive the conductive nozzle to rotate. At the same time, the rotating body 11 will also drive the cleaning member 12 to move relative to the inner wall of the nozzle, so that the cleaning member 12 can scrape off the splashes attached to the inner wall of the nozzle, thereby achieving the purpose of cleaning the nozzle. Since the process of disassembling the conductive nozzle and the process of cleaning the nozzle are combined, not only the original process of replacing the conductive nozzle is simplified, but also the time spent on replacing the conductive nozzle is saved. It should be noted that the first end 111 extends into the nozzle from the opening at the end of the nozzle where the welding wire extends, and as the body 11 is extended, the conductive nozzle is gradually extended into the clamping groove 113 until the groove wall of the clamping groove 113 is clamped with the outer wall of the conductive nozzle. It should also be noted that the entire process of replacing the conductive nozzle before the improvement takes about 45 seconds per time, while the entire process of replacing the conductive nozzle using the workpiece replacement sleeve 1 takes about 27 seconds per time. Therefore, using the workpiece replacement sleeve 1 to replace the conductive nozzle effectively reduces the time spent on replacing the conductive nozzle.
[0029] In one embodiment, the slot wall of the slot 113 includes two oppositely arranged clamping walls 1131 and a connecting wall 1132 connecting the two clamping walls 1131, and the two clamping walls 1131 are used to respectively abut against the clamping parts on both sides of the conductive nozzle, so that the slot 113 can be clamped and matched with the conductive nozzle. The two clamping walls 1131 are used to respectively abut against the clamping parts on both sides of the conductive nozzle, so that the torque acting on the body 11 can be transmitted to the conductive nozzle, and drive the conductive nozzle to rotate with the body. It should be noted that in the prior art, the installation and removal of the conductive nozzle relies on a wrench, and the clamping parts on both sides of the conductive nozzle are clamped or clamped by the wrench, and then the conductive nozzle is installed and removed. Therefore, the clamping parts on both sides of the conductive nozzle are existing structures, so the workpiece replacement sleeve 1 can adapt to the existing conductive nozzle without redesigning the conductive nozzle, thereby ensuring the adaptability of the workpiece replacement sleeve 1.
[0030] In one embodiment, the bottom wall of the slot 113 is provided with an extension slot 114, and the extension slot 114 can accommodate part of the body 11 of the conductive nozzle. In order to avoid the phenomenon that the end of the conductive nozzle has contacted the bottom wall of the slot 113 before the slot 113 forms a snap fit with the outer wall of the conductive nozzle, the extension slot 114 is provided to accommodate the part of the conductive nozzle that exceeds the slot 113, so as to ensure that the inner wall of the slot 113 can be smoothly snap-fitted with the outer wall of the conductive nozzle; and because the extension slot 114 is provided, the length range of the conductive nozzle that can be adapted by the body 11 is increased, thereby improving the adaptability of the workpiece replacement sleeve 1.
[0031] In one embodiment, the clamping slot 113 and the extension slot 114 are coaxially arranged and both extend along the axial direction of the body 11. The extension slot 114 and the clamping slot 113 are coaxially arranged to prevent the conductive tip from interfering with the slot wall of the extension slot 114 when the conductive tip is inserted into the extension slot 114.
[0032] In one embodiment, the second end 112 protrudes in a direction away from the first end 111 to form a connecting section 1121, and the connecting section 1121 is used to connect with the handle. By setting the connecting portion to connect with the handle, the staff can drive the body 11 to rotate through the handle.
[0033] In one embodiment, the cleaning member 12 is spirally wound around the periphery of the main body 11 to form a thread-like structure. This arrangement can not only effectively remove splashes attached to the inner wall of the nozzle, but also the falling splashes will be sent out of the nozzle by the cleaning member 12 as the main body 11 rotates.
[0034] In one embodiment, the main body 11 and the cleaning member 12 are integrally formed, which is convenient for processing and production.
[0035] In one embodiment, the cleaning member 12 includes a sleeve and a plurality of cleaning portions arranged on the outer wall of the sleeve, the cleaning portions are used to abut against the inner wall of the nozzle, and the sleeve is sleeved on the periphery of the body 11. In this embodiment, the sleeve and the body 11 are detachably connected, so that the cleaning member 12 can be cleaned separately, wherein the sleeve can be a rubber sleeve, and the cleaning portion can be a protrusion on the outer surface of the sleeve, or a structure such as rubber bristles, and the provision of multiple cleaning portions helps to improve the cleaning ability of the cleaning member 12.
[0036] In addition, the utility model also provides a workpiece replacement tool, which includes a handle and the above-mentioned workpiece replacement sleeve 1, and the handle is engaged with the second end 112 so that the handle can drive the conductive nozzle to rotate through the body 11. Since the workpiece replacement tool adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0037] In one embodiment, the handle is a torque handle. For the installation of the conductive nozzle, if the operator applies too much force when installing the conductive nozzle, the welding gun head will be deviated, which will cause the welding angle to change, resulting in defective products and a large number of defective products that need to be repaired, which is time-consuming and labor-intensive. The torque value of the conductive nozzle is generally 25N·m. Exceeding this torque will cause the conductive nozzle to break teeth, which will cause the entire equipment to stop running, affecting the production efficiency; and if the operator applies too much torque when installing the conductive nozzle, it is easy to cause the welding gun head and the conductive nozzle thread to be squeezed, causing thread damage and slipping, resulting in the welding gun head being scrapped; and in this embodiment, a torque handle is used, specifically a handle of a torque screwdriver, the torque handle is connected to the connecting section 1121, and the torque of the torque handle is adjusted to a reasonable value, generally 12N·m. When the torque handle is used to install the conductive nozzle, when the torque is greater than 12N·m during the tightening process, the torque handle will automatically break the force, thereby avoiding the situation of twisting over the torque value, and effectively solving the problem of uneven force.
[0038] The above are only preferred implementations of the utility model, and do not limit the patent scope of the utility model. All equivalent structural changes made based on the concept of the utility model and the contents of the description and drawings of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
