Description

Technical Field

[0001] This utility model relates to the field of welding torch nozzle processing technology, specifically to a welding torch nozzle boring and chamfering machine. Background Technology

[0002] As a key consumable in welding equipment, the precision of the hole structure of the welding nozzle directly affects the gas protection effect and welding quality. During the processing, the hole of the welding nozzle needs to be processed by deep hole drilling or boring. However, after processing, burrs or sharpening will inevitably occur, so chamfering and finishing processes are also required.

[0003] In existing technologies, such as Chinese Patent Publication No. CN215788087U, a novel tube boring processing equipment is disclosed. This equipment clamps the idler roller tube using a clamping device, and a servo motor drives a cutting tool device to perform processing operations on the idler roller tube. The processing tool and tool holder in the cutting tool device are detachably connected. The processing tool is one of three types: a tube boring tool, a tube trimming tool, or a tube chamfering tool. A single clamping of the idler roller tube can achieve all three processing methods: tube boring, tube trimming, or tube chamfering. That is, by changing the tool, the boring and chamfering processes of the tube can be achieved. However, in actual use, this processing equipment requires frequent tool changes, affecting the product forming accuracy, failing to guarantee product consistency, and having low processing efficiency.

[0004] Therefore, it is necessary to propose a welding gun nozzle boring and chamfering machine to at least partially solve the problems existing in the prior art. Utility Model Content

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] The present invention will now be further described with reference to the accompanying drawings.

[0034] like Figures 1-9 As shown, the welding gun nozzle boring and chamfering machine provided in this embodiment includes:

[0035] The material is arranged in sequence along the material movement direction as follows: loading station 1, boring station 2, chamfering station 3, closing station 4, and discharging station 5. There are three boring stations 2, and the feeding side of the three boring stations 2 is equipped with a first conveying component 6. The feeding side of the chamfering station 3, closing station 4, and discharging station 5 is equipped with a second conveying component 7.

[0036] The working principle and beneficial effects of this utility model are as follows:

[0037] In this embodiment, the welding nozzle boring and chamfering machine is used as follows: The loading station 1 transfers the stored welding nozzle outer tube to the first conveying component 6, which then transports the material to the boring station 2 for boring. After boring, the material is removed and conveyed to the next boring station 2 until all three boring stations 2 are completed. The first conveying component 6 then transfers the bored material to the end, and the second conveying component 7 transfers the material to the chamfering station 3, where it is removed after chamfering. The second conveying component 7 then transports the material to the closing station 4, where it is removed after closing. Finally, the second conveying component 7 transports the material to the discharge station 5 for discharge.

[0038] The welding gun nozzle boring and chamfering machine provided in this embodiment has a boring station 2, a chamfering station 3 and a finishing station 4 set on the machine body. Through the coordinated action of the first conveying component 6 and the second conveying component 7, the material is transferred between each station. The material position is more accurate and the transfer is more convenient. The overall processing efficiency of the equipment is improved, and the repeatability of the product and the consistency of the processing technology are significantly improved.

[0039] like Figure 2 As shown, in one embodiment, the feeding station 1 includes an outer tube hopper 11, a pusher 12, and an outer tube conveyor belt 13. The outer tube hopper 11 contains welding gun nozzle outer tube materials; the pusher 12 is connected to the side of the outer tube hopper 11; and the outer tube conveyor belt 13 is connected to the discharge port of the pusher 12.

[0040] The working principle and beneficial effects of the above scheme are as follows:

[0041] According to production needs and silo capacity, an appropriate amount of welding nozzle outer tube material is placed in the outer tube silo 11. Then, the material in the outer tube silo 11 is pushed onto the outer tube conveyor belt 13 by the pusher 12. The outer tube conveyor belt 13 moves the material to the picking position, waiting for the picking station 8 to pick it up. Using the pusher 12 for feeding enables continuous and stable material supply and automated control of the processing production process, improving production efficiency and reducing labor costs.

[0042] like Figure 3 As shown, in one embodiment, a material picking station 8 is provided between the loading station 1 and the first conveying component 6. The material picking station 8 includes a material picking lateral movement mechanism 81, a material picking lifting mechanism 82, a material picking rotation mechanism 83, and a first material picking clamp 84. The material picking lateral movement mechanism 81 is located on one side of the first conveying component 6. The material picking lifting mechanism 82 is connected to the lateral movement end of the material picking lateral movement mechanism 81. The material picking rotation mechanism 83 is connected to the lifting end of the material picking lifting mechanism 82. The three first material picking clamps 84 are connected to the rotation end of the material picking rotation mechanism 83, and the included angle between adjacent first material picking clamps 84 is set to 90 degrees.

[0043] The working principle and beneficial effects of the above scheme are as follows:

[0044] The material handling mechanism 81 at the material handling station 8 moves the first material handling clamp 84 above the material handling position of the outer tube conveyor belt 13, aligning the first material handling clamp 84 with the material. The material handling lifting mechanism 82 descends and handles the material through the first material handling clamp 84. Then, the material handling lifting mechanism 82 rises, activating the material handling rotation mechanism 83 to rotate, aligning the second material handling clamp 84 with the material. The material handling lifting mechanism 82 then descends and handles the material through the second material handling clamp 84. This process is repeated until all three material handling clamps 84 are full. Finally, the material handling mechanism 81 moves the first material handling clamp 84 above the first conveying assembly 6, and the material is placed on the first conveying assembly 6 through lifting and rotation. Through this structural design, the material handling station 8 can simultaneously transfer three materials, improving processing and conveying efficiency and ensuring a continuous supply of materials.

[0045] like Figure 4 As shown, in one embodiment, the first conveying assembly 6 includes a circulating chain 61, a chain rotation motor 62, a material transfer slide 63, and a material positioning cylinder 64. Multiple sprockets are meshed on the inner side of the circulating chain 61. The output end of the chain rotation motor 62 is connected to the sprocket at one end of the circulating chain 61. The material transfer slide 63 is located at the other end of the circulating chain 61 and away from the loading station 1. Three sets of material positioning cylinders 64 are symmetrically arranged on both sides of the circulating chain 61, and the positions of the three sets of material positioning cylinders 64 correspond one-to-one with the three boring stations 2. Multiple sets of chain unloading carriers 60 are provided on the circulating chain 61.

[0046] The working principle and beneficial effects of the above scheme are as follows:

[0047] Material handling station 8 places the material onto the chain feeding carrier 60 of the first conveying assembly 6. Driven by the chain rotation motor 62, the sprocket inside the circulating chain 61 rotates, which in turn drives the circulating chain 61 to transfer the material to the next boring station 2 for processing. After all boring stations 2 have completed their processing, the material is conveyed to the material transfer chute 63 and slides onto the subsequent second conveyor belt 65. The material positioning cylinder 64 actuates to position the transferred material precisely at the preset position on the chain feeding carrier 60, ensuring accurate positioning after transfer. The first conveying assembly 6 completes the material transfer between each boring station 2, enabling the material to continuously complete multiple boring processes and improving processing efficiency.

[0048] like Figure 5 As shown, in one embodiment, the boring station 2 includes a boring machine body 21. The boring machine body 21 is equipped with a power head Y-axis moving mechanism 22, a tool holder X-axis moving mechanism 24, and a boring material handling mechanism. The output end of the power head Y-axis moving mechanism 22 is connected to a power head 23, and the input end of the power head 23 is connected to a boring motor 25 through a transmission box. The tool holder X-axis moving mechanism 24 is pneumatically driven, and a boring tool is connected to the tool holder X-axis moving mechanism 24. The boring material handling mechanism includes a material handling rotating arm 26 and a material handling lifting arm 27. The material handling rotating arm 26 is rotatably mounted on the boring machine body 21, and the material handling lifting arm 27 is connected to the material handling rotating arm 26. The end of the material handling lifting arm 27 is equipped with a material gripper.

[0049] The working principle and beneficial effects of the above scheme are as follows:

[0050] During boring station 2, the material-picking rotary arm 26 is rotated above the circulating chain 61, and the material-picking lifting arm 27 descends to pick up the material through the material grippers. Then, the material-picking lifting arm 27 rises, and the material-picking rotary arm 26 rotates to the power head 23, where the material is placed and clamped. Next, the Y-axis moving mechanism 22 is activated, moving the power head 23 closer to the boring tool. The boring motor 25 is started, driving the power head 23 to rotate via the transmission box. Simultaneously, the tool holder X-axis moving mechanism 24 is activated, moving the boring tool. Through Y-axis and X-axis interpolation, the welding nozzle is bored. After machining, the material clamping is released, and the material is removed through the material grippers. Using the rotation of the material-picking rotary arm 26 and the lifting motion of the material-picking lifting arm 27, the machined material is transferred to the circulating chain 61, allowing it to be transported to the next station for the next processing step. The Y-axis is perpendicular to the length of the circulating chain 61, and the X-axis is parallel to the length of the circulating chain 61.

[0051] like Figure 6 As shown, in one embodiment, the first conveying assembly 6 further includes a second conveyor belt 65, a rotary motor 66, a conveyor belt discharge cylinder 67, a material positioning cylinder 68, and a material limiting part 69. The extension direction of the second conveyor belt 65 is perpendicular to the extension direction of the circulating chain 61, and one end of the second conveyor belt 65 is located below the material transfer chute 63. Multiple pulleys are connected inside the second conveyor belt 65. The output shaft of the rotary motor 66 is connected to the pulley at one end of the second conveyor belt 65. The conveyor belt discharge cylinder 67 is disposed on one side of the second conveyor belt 65 and corresponds to the outlet of the material transfer chute 63. The material limiting part 69 is disposed at the material picking position of the second conveyor belt 65. The material positioning cylinder 68 is disposed on one side of the second conveyor belt 65 and corresponds to the material limiting part 69.

[0052] The working principle and beneficial effects of the above scheme are as follows:

[0053] The material slides along the material transfer chute 63 onto the second conveyor belt 65. The conveyor belt discharge cylinder 67 is activated to block and release the material, enabling the discharge of a single piece of material. After discharge, the single piece of material moves with the second conveyor belt 65 to the material limiting position, where it is blocked and limited by the material limiting part 69. Then, the material positioning cylinder 68 is activated to straighten the material at the limiting position, awaiting extraction by the second conveying component 7 to proceed to the subsequent chamfering station 3. Through this structural design, the second conveyor belt 65 connects the first conveying component 6 and the second conveying component 7, achieving precise connection of the boring and chamfering processes. The discharge cylinder 67 releases individual materials, while the material limiting part 69 and the material positioning cylinder 68 ensure accurate material position and orientation, facilitating accurate subsequent material retrieval.

[0054] like Figure 7 As shown, in one embodiment, the second conveying assembly 7 includes: a material picking transverse module 71, a material picking transverse frame 72, a material picking rotation module 73, a material picking lifting module 74, and a second material picking clamp 75; the material picking transverse module 71 is disposed on the feeding side of the chamfering station 3, the closing station 4, and the discharge station 5; the material picking transverse frame 72 is connected to the transverse end of the material picking transverse module 71; the three material picking rotation modules 73 are mounted on the material picking transverse frame 72; the material picking lifting module 74 is connected to the rotating end of the material picking rotation module 73; and the second material picking clamp 75 is connected to the bottom of the lifting section of the material picking lifting module 74.

[0055] The working principle and beneficial effects of the above scheme are as follows:

[0056] When the second conveying assembly 7 is in use, a material-grabbing assembly is positioned above the limiting position of the second conveyor belt 65. Through the lifting action of the material-grabbing lifting module 74 and the rotation action of the material-grabbing rotating module 73, the second material-grabbing clamp 75 contacts and clamps the material at the limiting position, then raises the material to a certain height. The material-grabbing transverse module 71 moves the material-grabbing transverse frame 72, transferring the material to the next chamfering station 3 for chamfering processing. After chamfering, the material is removed by the coordinated action of the material-grabbing lifting module 74, the material-grabbing rotating module 73, and the second material-grabbing clamp 75, and then moved to the closing station 4 by the transverse module 71 for closing processing. Similarly, after closing processing, the material is removed by the coordinated action of the material-grabbing lifting module 74, the material-grabbing rotating module 73, and the second material-grabbing clamp 75, and then moved to the discharge station 5 by the transverse module 71.

[0057] Through the above structural design, three material picking components are set on the material picking transverse frame 72, which can simultaneously realize the material conveying from the second conveying component 7 to the chamfering station 3, the material conveying from the chamfering station 3 to the closing station 4, and the material conveying from the closing station 4 to the discharge station 5, so that the chamfering, closing and discharge processes are carried out simultaneously, improving the conveying and processing efficiency.

[0058] like Figure 8 As shown, in one embodiment, the chamfering station 3 includes a chamfering machine body 31. The chamfering machine body 31 is provided with a feed slide 32 and a tool holder 33. The tool holder 33 is located on the side of the feed slide 32 near the second conveying component 7. A chamfering power head 34 is slidably disposed on the feed slide 32. The power input end of the chamfering power head 34 is connected to the chamfering power head motor 35 through a transmission box. A tool holder 36 is installed on the tool holder 33.

[0059] The working principle and beneficial effects of the above scheme are as follows:

[0060] After the material is transferred to chamfering station 3, it is placed in the chamfering power head 34 for clamping. The feed slide 32 is started, moving the chamfering power head 34 closer to the tool holder 36 on the tool holder 33. At the same time, the chamfering power head motor 35 drives the chamfering power head 34 to rotate through the transmission box, causing the material to rotate. The material then contacts the tool on the tool holder 36 to perform the chamfering process. After processing, the material is extracted through the second conveying assembly 7 and transferred to the next finishing station 4.

[0061] like Figure 9As shown, in one embodiment, the closing station 4 includes a closing machine body 41, a hydraulic station 42, a closing push rod 43, a closing die 44, a material ejection cylinder 45, and a material ejection rod 46. The hydraulic station 42 is installed on the side of the closing machine body 41 away from the second conveying assembly 7; the closing push rod 43 is connected to the output end of the hydraulic station 42 and moves along the length of the closing machine body 41; the closing die 44 is installed at the center of the closing machine body 41; the material ejection cylinder 45 is installed on the side of the closing machine body 41 close to the second conveying assembly 7; and the material ejection rod 46 is connected to the output end of the material ejection cylinder 45 and extends into the closing die 44.

[0062] The working principle and beneficial effects of the above scheme are as follows:

[0063] After the material is transferred to the closing station 4, the material is mounted on the closing push rod 43 by the coordinated action of the material lifting module 74, the material rotating module 73, and the second material clamp 75. Then, the hydraulic station 42 is started to feed the material on the closing push rod 43 into the closing mold 44 until it is closed to the preset size. After the closing is completed, the ejector cylinder 45 is started to drive the ejector rod 46 to move, and the ejector rod 46 ejects the material in the closing mold 44. Then, the material is extracted by the coordinated action of the material lifting module 74, the material rotating module 73, and the second material clamp 75, and moved to the discharge station by the second conveying component 7.

[0064] like Figure 1 As shown, in one embodiment, the discharge station 5 includes an inclined finished product discharge plate 51.

[0065] The working principle and beneficial effects of the above scheme are as follows:

[0066] The processed material is transferred to the discharge plate 51 by the second conveying component 7. The discharge plate 51 is inclined to facilitate the collection and discharge of finished material.
