Description

Technical Field

[0001] This application relates to the field of microporous tube processing technology, specifically to a microporous tube polishing device for conductive nozzles. Background Technology

[0002] The conductive tip micro-tube is a key component used in welding equipment and is the basic tubing for manufacturing conductive tips. Its core feature is a precise micro-hole running through the entire tube, which serves as the channel for feeding the welding wire. The inner diameter of this micro-hole requires extremely high precision. The outer diameter of the tube varies depending on different welding requirements and equipment specifications, generally ranging from a few millimeters to over ten millimeters. The straight cylindrical shape is the most common shape for conductive tip micro-tubes, where both the micro-hole and the tube body are straight.

[0003] Existing methods for polishing conductive nozzle micro-tubes using an internal polishing machine have certain drawbacks in fixing the micro-tube. To ensure that the two sets of clamping components are precisely aligned on the same axis, the operator must simultaneously rotate the adjusting screw. This process requires the operator to constantly monitor the rotation amplitude and speed of the screws on both sides. Slight errors can lead to inconsistent movement of the clamping plates on both sides, causing the two sets of clamping components to deviate from the same axis. Once the clamping components are misaligned, the relative position between the micro-tube's inner hole and the polishing tool cannot remain stable and precise during subsequent polishing operations, thus affecting the polishing of the micro-tube's inner hole. Therefore, it is necessary to provide a micro-tube polishing device for conductive nozzles to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0011] Furthermore, the fixing assembly includes two sets of second slide rails installed at both ends of the inner wall of the concave cover, two sets of sliders slidably mounted on the second slide rails, and fasteners connected to the sliders;

[0012] The two sets of sliders are spaced apart, and a connecting seat is connected between the two sets of sliders that are vertically arranged.

[0013] Furthermore, an anti-slip pad is provided at the contact position between the clamping ring and the microporous tube, and the anti-slip pad covers the clamping ring.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-4 As shown, this application provides a microporous tube polishing device for conductive nozzles, including a worktable 1, a polishing component 2 installed on the worktable 1, the polishing component 2 being used to polish the inner hole of the microporous tube, and the polishing component 2 including a mounting plate 21 fixedly installed on the worktable 1, two sets of first slide rails 22 fixedly installed on the mounting plate 21, and a sliding platform 23 slidably installed on the two sets of first slide rails 22.

[0028] A first motor 24 is fixedly installed at one end of the mounting plate 21, and a first lead screw 25 is fixedly installed at the output end of the first motor 24. The sliding platform 23 is threadedly connected to the first lead screw 25, and one end of the first lead screw 25 is connected to a bearing at one end of the mounting plate 21. Thus, the first motor 24 is adapted to start so as to drive the first lead screw 25 to rotate. As the first lead screw 25 rotates, the sliding platform 23 slides along the straight direction of the first slide rail 22.

[0029] A second motor 26 is fixedly installed on the sliding platform 23, and a polishing wheel 27 is fixedly installed at the output end of the second motor 26. The polishing wheel 27 is adapted to rotate with the output end of the second motor 26 to polish the inner hole of the microporous tube.

[0030] In actual operation, the microporous tube to be polished is first fixed in place, allowing the polishing wheel 27 to precisely extend into the inner hole of the microporous tube. At this time, the first motor 24 controls the sliding platform 23 to move the polishing wheel 27 along the axial direction within the inner hole of the microporous tube, while the second motor 26 ensures the continuous rotation of the polishing wheel 27. During this process, the surface of the polishing wheel 27 is in close contact with the inner wall of the microporous tube, using friction to polish the hole wall, removing burrs, unevenness, and impurities, thus completing the polishing of the inner hole of the microporous tube.

[0031] In order to clamp and fix the microporous tube, such as Figures 2-4As shown, the worktable 1 has a concave cover (not shown in the figure), and a fixing component 3 is installed on the inner wall of the concave cover. The fixing component 3 is used to clamp the micro-tube, and the fixing component 3 includes two sets of second slide rails 33 fixedly installed at both ends of the inner wall of the concave cover. Two sets of sliders 34 are slidably installed on the second slide rails 33. The sliders 34 are adapted to slide along the straight direction of the second slide rails 33. It should be noted that by connecting fasteners to the sliders 34, the fasteners are adapted to thread through the sliders 34 and connect to the second slide rails 33, so as to fix the sliders 34 at a certain position on the second slide rails 33.

[0032] The two sets of sliders 34 are spaced apart, and a connecting seat 35 is fixedly connected between the two vertically arranged sets of sliders 34. Guide rods (not shown in the figure) are located near both ends of the connecting seat 35, and a second lead screw 36 is bearing-mounted at the center of the connecting seat 35. The second lead screw 36 is rotatable, and a movable sleeve 37 is threadedly connected to the second lead screw 36. The two ends of the movable sleeve 37 are slidably connected to the guide rods (see reference). Figure 3 Thus, when the second lead screw 36 rotates, the movable sleeve 37 can slide along the straight direction of the two sets of guide rods;

[0033] Two sets of right-angle rods 38 are fixedly installed on the movable sleeve 37, and a clamping ring 39 is bolted to one end of the two sets of right-angle rods 38. The clamping ring 39 is suitable for contacting the surface of the microporous tube. At the same time, an anti-slip pad (not shown in the figure) is provided at the contact position between the clamping ring 39 and the microporous tube. The anti-slip pad covers the clamping ring 39 to increase the contact friction between the clamping ring 39 and the microporous tube.

[0034] Furthermore, a first support part 31 and a second support part 32 are fixedly installed on the workbench 1. Both the first support part 31 and the second support part 32 are semi-circular to facilitate initial support of the microporous tube.

[0035] During the preparation stage, the first support part 31 and the second support part 32 provide initial support for the micro-tube to be clamped, allowing the micro-tube to be stably placed on the worktable 1, facilitating subsequent fixing operations. The operator then loosens the fasteners connecting the slider 34 and the second slide rail 33, allowing the slider 34 to slide freely along the straight direction of the second slide rail 33. After adjusting the slider 34 to the appropriate position according to the length of the micro-tube, the fasteners are tightened again to fix the slider 34, thus determining the position of the connecting seat 35 and initially adapting to micro-tubes of different lengths.

[0036] When the operator rotates the second lead screw 36, the rotational motion of the second lead screw 36 is converted into the sliding motion of the movable sleeve 37 along the linear direction of the guide rod because the movable sleeve 37 is threadedly connected to the second lead screw 36 and its two ends are slidably connected to the guide rod. The sliding motion of the movable sleeve 37 is transmitted to the clamping ring 39 through two sets of fixedly installed right-angle rods 38. The clamping ring 39 is bolted to one end of the right-angle rod 38 for easy replacement according to the diameter of the microporous tube. When the movable sleeve 37 slides, the clamping ring 39 moves closer to or further away from the microporous tube. When the clamping ring 39 contacts the surface of the microporous tube, the anti-slip pad covering the contact position between the clamping ring 39 and the microporous tube plays a role, increasing the contact friction between the two and ensuring that the microporous tube is firmly clamped in a fixed position. Even if it is subjected to external force during subsequent polishing operations, it will not shift, ensuring the smooth progress of the polishing work.

[0037] Furthermore, the synchronous drive clamping ring 39 clamps the micro-tube to maintain its coaxiality, such as... Figures 2-4 As shown, one end of the second lead screw 36 passes through the concave cover between the two sets of sliders 34, and a drive unit is installed on the outer wall of the concave cover. The drive unit includes a gear 310 fixedly installed on one end of the second lead screw 36. At the same time, fixed side plates 311 are fixedly installed on both sides of the outer wall of the concave cover, and a guide rail 312 is fixedly installed on the fixed side plate 311. A sliding buckle plate 313 is slidably installed on the guide rail 312. A sliding buckle groove (not shown in the figure) adapted to the guide rail 312 is opened on the sliding buckle plate 313.

[0038] A rack 314 is fixedly installed at the lower end of the sliding plate 313. The rack 314 meshes with two sets of racks 314 on the same plane in the default state. A handle 315 is fixedly installed on the sliding plate 313, and a push rod 316 is connected between the two sets of handles 315. The push rod 316 is suitable for synchronously pushing the two sets of sliding plates 313 to move.

[0039] When the clamping ring 39 needs to be driven synchronously to clamp the micro-tube, the operator pushes the push rod 316 to drive the two sets of grips 315 to move synchronously, thereby achieving synchronous movement of the two sets of sliding plates 313. The rack 314 installed at the lower end of the sliding plate 313 moves along a predetermined direction. Since the rack 314 is tightly meshed with the two sets of gears 310 installed at the end of the second lead screw 36 in the default state, the linear movement of the rack 314 will cause the gears 310 to rotate. Since the gears 310 at the ends of the two sets of second lead screws 36 mesh with the same rack 314 at the same time, when the rack 314 moves, the two gears 310 will rotate synchronously and in the same direction, thereby driving the two second lead screws 36 to rotate synchronously.

[0040] Since the second lead screw 36 is threadedly connected to the movable sleeve 37, and both ends of the movable sleeve 37 are slidably connected to the guide rod, the synchronous rotation of the second lead screw 36 will cause the two sets of movable sleeves 37 connected to it to slide synchronously and at equal distances along the guide rod. The movable sleeve 37 is also fixedly connected to the clamping ring 39 through the right-angle rod 38, which ultimately allows the two sets of clamping rings 39 to move synchronously closer to or further away from the microporous tube, and always remain on the same axis.

[0041] In this application, in order to prevent dust from affecting the operation of gear 310 and rack 314 during polishing of the inner hole of the microporous tube, dust covers can be installed on both sides of the concave cover. The dust covers are used to shield gear 310 and rack 314, and at the same time, side slots for rack 314 to move can be opened on the dust covers.

[0042] In summary: During the preparation stage, the semi-circular first support 31 and second support 32, fixedly installed on the workbench 1, play their role first, stably placing the microporous tube to be polished on them, providing a foundation for subsequent fixing operations. Next, the operator loosens the fasteners on the slider 34 that are threadedly connected to the second slide rail 33, and according to the length of the microporous tube, pushes the slider 34 to slide along the second slide rail 33 to a suitable position, then tightens the fasteners again, thereby determining the position of the connecting seat 35 and initially adapting it to microporous tubes of different lengths.

[0043] During the clamping phase, when the microporous tube needs to be clamped, the operator pushes the push rod 316 connecting the two sets of handles 315. The push rod 316 drives the handles 315, which in turn causes the two sets of sliding plates 313 to slide synchronously on the guide rail 312. The rack 314 at the lower end of the sliding plate 313 moves accordingly. Since the rack 314 meshes with the two sets of gears 310 installed at the end of the second lead screw 36, the linear motion of the rack 314 is converted into the rotation of the gears 310, causing the two second lead screws 36 to rotate synchronously. When the second lead screw 36 rotates, the movable sleeve 37, which is threaded to it and slidably connected to the guide rod at both ends, slides synchronously and equidistantly along the guide rod, driving the clamping ring 39 to synchronously move closer to or away from the microporous tube through the right-angle rod 38. At this time, the anti-slip pad covering the contact position between the clamping ring 39 and the microporous tube plays a role, ensuring that the microporous tube is firmly clamped on the same axis.

[0044] During the polishing stage, after the microporous tube is properly clamped, the first motor 24 at one end of the mounting plate 21 is started. Its output end drives the first lead screw 25 to rotate. The sliding platform 23, which is threadedly connected to the first lead screw 25, slides linearly along the first slide rail 22, allowing the polishing wheel 27 mounted on the sliding platform 23 to penetrate deep into the inner hole of the microporous tube. At the same time, the second motor 26 is started, driving the polishing wheel 27 to rotate continuously. Under the coordinated operation of the first motor 24 and the second motor 26, the polishing wheel 27 moves along the axis in the inner hole of the microporous tube, and its surface is in close contact with the inner hole wall. It polishes the hole wall by friction, removing burrs, unevenness, and impurities, thus completing the polishing operation of the inner hole of the microporous tube. The entire process meets the strict requirements of high-precision machining for the coaxiality of the microporous tube clamping and the polishing quality.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
