Technical Field

[0001] This utility model relates to the field of welding wire grinding technology, and in particular to a device for grinding welding wire. Background Technology

[0002] Welding wire is a metal wire used as filler metal or simultaneously as a conductor in welding. Welding wire grinding equipment is a specialized mechanical device used to treat the surface of welding wire, removing contaminants such as oxide layers, rust, and oil through mechanical grinding and polishing. In welding operations, the cleanliness of the welding wire surface is one of the key factors affecting weld quality. Grinding the welding wire surface before welding to remove rust, scale, and oil, revealing a metallic luster, is a necessary step to ensure welding quality and improve welding efficiency.

[0003] Existing welding wire grinding equipment is mostly a fixed-point grinding structure, which requires manual feeding of the welding wire. The reciprocating feed speed is difficult to control evenly, and problems such as grinding blind spots or local over-grinding are easy to occur. At the same time, there is a lack of reliable guiding and limiting structure, and the welding wire is prone to swaying and bending during the grinding process, making it difficult to guarantee grinding accuracy and quality. Therefore, a welding wire grinding device is designed to provide an alternative technical solution to the above technical problems. Utility Model Content

[0004] Therefore, it is necessary to provide a device for grinding welding wire to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A device for grinding welding wire includes a grinding table and a clamping block, wherein a grinding mechanism is provided above the grinding table; A support column is fixedly connected to the upper surface of the grinding table, a first limiting tube is fixedly connected to the side wall of the support column, a column is fixedly connected to the upper surface of the grinding table, and a second limiting tube is fixedly connected to the side wall of the column. A reciprocating mechanism and a clamping mechanism are provided between the grinding table and the clamping block. The clamping mechanism is located at the drive end of the reciprocating mechanism, and the clamping block is located at the upper end of the clamping mechanism. The clamping mechanism is used to clamp and fix the welding wire mounted in the drive rotation structure; The grinding table has a through groove at the position corresponding to the grinding mechanism.

[0006] As a preferred embodiment of the equipment for grinding welding wire provided by this utility model, the reciprocating mechanism includes a second motor fixedly connected inside the grinding table, and a transmission rod is fixedly provided at the output end of the second motor, and the transmission rod is rotatably connected to the grinding table. A turntable is fixedly connected to the top of the transmission rod; The end face of the turntable is fixedly connected to a first connecting shaft.

[0007] In a preferred embodiment of the welding wire grinding device provided by this utility model, a pull plate is rotatably connected to the upper end of the first connecting shaft, and a sliding block is rotatably connected to the end of the pull plate away from the turntable through the second connecting shaft. A limiting plate is fixedly connected to the upper surface of the grinding table, and the limiting plate passes through the bottom of the sliding block and is horizontally slidably connected to it.

[0008] In a preferred embodiment of the welding wire grinding device provided by this utility model, the clamping mechanism includes a fixed block fixedly connected to the top of the sliding block, and a bidirectional lead screw is rotatably connected inside the fixed block. A knob is fixedly connected to the end of the bidirectional lead screw; The clamping mechanism also includes a support block that is fixedly connected to the outer wall of the clamping block.

[0009] In a preferred embodiment of the welding wire grinding device provided by this utility model, the fixed block is symmetrically and horizontally slidably connected with a threaded block, and the threaded block is threadedly connected to a bidirectional lead screw. A connecting block is fixedly connected to the upper surface of the threaded block, and a sliding groove is provided inside the fixed block. The connecting block is horizontally slidably connected inside the sliding groove. The connecting block is fixedly connected to the support block.

[0010] As a preferred embodiment of the equipment for grinding welding wire provided by this utility model, the grinding mechanism includes a first motor fixedly connected to the upper surface of the grinding table, and a grinding block is fixedly connected to the output end of the first motor. The end of the second limiting tube is provided with a through hole; The first limiting tube and the second limiting tube are arranged coaxially at the through hole position.

[0011] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0012] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects: This utility model provides a device for grinding welding wire. Through a reciprocating mechanism, the clamping block and the welding wire reciprocate along the axial direction. With the coaxial guidance and limiting of the first and second limiting tubes, the straightness of the welding wire is ensured during the grinding process. This allows the grinding working surface to evenly cover the entire area to be ground, avoiding the uneven grinding problem caused by manual feeding, effectively improving grinding consistency, removing the oxide layer and rust on the surface of the welding wire, and ensuring the forming quality of subsequent welding operations. At the same time, the automatic reciprocating operation eliminates the need for manual pushing, effectively reducing the labor intensity.

[0013] This invention uses a clamping mechanism to hold and fix the end of the welding wire. The clamping joint has a built-in rotating structure. When the welding wire is subjected to the tangential force of the grinding block during the grinding operation, the welding wire can be ground in all directions around its entire circumference. There is no need to manually flip and adjust the grinding surface in the middle. The entire grinding operation can be completed in one clamping. The operation is convenient and efficient. At the same time, the bidirectional centering clamping structure can be adapted to welding wires of different diameters and specifications. The clamping is stable and does not slip, which effectively improves the safety and applicability of the grinding operation. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1: This example mainly discloses a device for grinding welding wire according to this application.

[0022] See Figure 1 and Figure 2 The equipment for grinding welding wire in this application includes a grinding table 1 and a clamping block 7, and a grinding mechanism 2 is provided above the grinding table 1. A support column 3 is fixedly connected to the upper surface of the grinding table 1, a first limiting tube 4 is fixedly connected to the side wall of the support column 3, a column 5 is fixedly connected to the upper surface of the grinding table 1, and a second limiting tube 6 is fixedly connected to the side wall of the column 5. A reciprocating mechanism 8 and a clamping mechanism 9 are provided between the grinding table 1 and the clamping block 7. The clamping mechanism 9 is located at the driving end of the reciprocating mechanism 8, and the clamping block 7 is located at the upper end of the clamping mechanism 9. The clamping mechanism 9 is used to clamp and fix the welding wire mounted in the drive rotating structure; The drive rotation structure is a welding wire rotation feeding device in the prior art. Its typical structure includes a drive motor, a transmission assembly, a bearing housing, and a rotating chuck. The drive motor drives the welding wire supported by the rotating chuck and the bearing housing to rotate around its own axis through the transmission assembly. In specific implementations, commercially available automatic wire feeding rotation devices such as the WireWizard WSS-100 welding wire straightener, the Lincoln MAXSA22 wire feeder head, the LORCHRF-06 robot wire feeding mechanism, or the PMLFWF-840 wire feeding mechanism can be used. The above structures are all mature prior art in this field, and their specific structures will not be limited in detail here.

[0023] A through groove 10 is provided at the position of the grinding table 1 corresponding to the grinding mechanism 2.

[0024] In actual use, the end of the welding wire to be ground is first passed through the second limiting tube 6 and the first limiting tube 4 in sequence to complete the initial guiding and positioning. Then, the clamping mechanism 9 is operated to clamp and fix the end of the welding wire. The clamping mechanism 9 clamps and fixes the welding wire in the drive rotating structure. The position of the welding wire is adjusted so that its outer circumference is in contact with the grinding working surface of the grinding mechanism 2. After the equipment is started, the grinding mechanism 2 rotates at high speed to perform circumferential grinding on the welding wire. The reciprocating mechanism 8 drives the clamping block 7 and the welding wire to move back and forth along the axial direction in sync, so as to achieve comprehensive and uniform grinding of the entire area to be ground. The metal debris generated by grinding is discharged and collected downward through the through groove 10. After grinding is completed, the clamping mechanism 9 can be released to take out the welding wire.

[0025] Example 2: This example discloses a specific reciprocating mechanism 8 based on Example 1.

[0026] See Figure 3 and Figure 4 The reciprocating mechanism 8 includes a second motor 801 fixedly connected inside the grinding table 1. The output end of the second motor 801 is fixedly provided with a transmission rod 802, which is rotatably connected to the grinding table 1. A turntable 803 is fixedly connected to the top of the transmission rod 802; The end face of the turntable 803 is fixedly connected to the first connecting shaft 804.

[0027] The upper end of the first connecting shaft 804 is rotatably connected to a pull plate 805, and the end of the pull plate 805 away from the turntable 803 is rotatably connected to a sliding block 807 via a second connecting shaft 806. A limiting plate 808 is fixedly connected to the upper surface of the grinding table 1. The limiting plate 808 passes through the bottom of the sliding block 807 and is horizontally slidably connected to it.

[0028] Therefore, the usage process and principle of the reciprocating mechanism 8 in this embodiment are as follows: After the equipment is started, the second motor 801 is powered on and runs. Its output end drives the transmission rod 802 to rotate synchronously. The turntable 803 at the top of the transmission rod 802 rotates in a fixed-axis circular motion. The first connecting shaft 804 on the end face of the turntable 803 moves in a circular motion synchronously with the turntable 803. The pull plate 805 converts the circular motion into linear reciprocating motion, pulling the sliding block 807 to slide in a horizontal linear reciprocating motion along the limiting plate 808. This, in turn, drives the clamping mechanism 9 above the sliding block 807 to move synchronously along the axial direction with the clamped welding wire, so that the grinding working surface can evenly cover the entire area to be ground of the welding wire. The bottom of the sliding block 807... The part is provided with a relief groove, which allows the limiting plate 808 to slide inside the relief groove to prevent deviation during the sliding process. Most existing welding wire grinding equipment is fixed-point grinding, which requires manual pushing of the welding wire for feeding. The operation is laborious and the reciprocating feed speed is uneven, which can easily lead to grinding blind spots or local over-grinding. This reciprocating mechanism 8 adopts a crank-slider transmission structure to automatically complete the axial reciprocating motion. The operation is stable and the stroke is constant, which improves the grinding uniformity. The limiting plate 808 provides lateral limiting and guidance for the sliding block 807 to ensure that the reciprocating motion is always along the welding wire axis and will not cause radial deviation, thus ensuring grinding accuracy and grinding quality.

[0029] Example 3: This example discloses a specific clamping mechanism 9 based on Example 1.

[0030] See Figure 5 The clamping mechanism 9 includes a fixed block 901 fixedly connected to the top of the sliding block 807, and a bidirectional lead screw 902 is rotatably connected inside the fixed block 901. A knob 903 is fixedly connected to the end of the bidirectional lead screw 902; The clamping mechanism 9 also includes a support block 907 that is fixedly connected to the outer wall of the clamping block 7.

[0031] The fixed block 901 has a threaded block 904 that is symmetrically and horizontally slidably connected inside, and the threaded block 904 is threadedly connected to the bidirectional lead screw 902. A connecting block 905 is fixedly connected to the upper surface of the threaded block 904. A sliding groove 906 is provided inside the fixed block 901, and the connecting block 905 is horizontally slidably connected inside the sliding groove 906. The connecting block 905 is fixedly connected to the support block 907.

[0032] Therefore, the usage process and principle of the clamping mechanism 9 in this embodiment are as follows: When clamping the welding wire, turning the knob 903 drives the bidirectional lead screw 902 to rotate synchronously. The two sections of threads with opposite directions on the bidirectional lead screw 902 synchronously drive the two threaded blocks 904 to slide towards each other along the slide groove 906. The threaded blocks 904 drive the support block 907 to move synchronously through the connecting block 905, so that the two clamping blocks 7 synchronously retract towards the middle, forming an opposing clamping of the welding wire with the self-rotating drive mechanism. After clamping, the welding wire is fixed. When it is necessary to remove the welding wire, turn the knob 903 in the opposite direction, and the bidirectional lead screw 902 rotates in the opposite direction, driving the two clamping blocks 7 to open synchronously in opposite directions, releasing the welding wire. It is stable and can be adapted to welding wires of different diameters. The adjustment operation is convenient and requires no additional tools.

[0033] Example 4: This example discloses a specific polishing mechanism 2 based on Example 1.

[0034] See Figure 3 The grinding mechanism 2 includes a first motor 201 fixedly connected to the upper surface of the grinding table 1, and a grinding block 202 fixedly connected to the output end of the first motor 201. The end of the second limiting tube 6 is provided with a through hole; The first limiting tube 4 and the second limiting tube 6 are arranged coaxially at their through holes.

[0035] Therefore, the specific usage process and principle of the grinding mechanism 2 in this embodiment are as follows: During the grinding operation, the first motor 201 is powered on and starts, driving the grinding block 202 to rotate at high speed. After the welding wire is guided by the coaxially arranged second limiting tube 6 and first limiting tube 4, its end is clamped and positioned by the clamping block 7. The clamping mechanism 9 has a built-in rotational support structure at the clamping engagement point, allowing the clamped end of the welding wire to rotate freely in the circumferential direction. The outer circumferential surface of the welding wire is in close contact with the side of the rotating grinding block 202. The high-speed rotating grinding block 202 applies a tangential grinding force to the surface of the welding wire. Combined with the welding wire's autonomous circumferential rotation relying on the rotational structure at the clamping point, the welding wire is made into a complete circle. The uniform cutting and grinding of the circumference surface removes the oxide layer, rust and burrs; during the grinding process, the reciprocating mechanism 8 synchronously drives the clamping mechanism 9 and the welding wire to move back and forth along the axis, and with the circumferential rotation of the welding wire, the entire circumference of the welding wire can be ground without dead angles in one clamping. The metal chips generated by grinding are discharged downward through the through groove 10 at the corresponding position of the grinding table 1, avoiding the accumulation of chips in the grinding area and affecting the grinding effect. The rotational grinding and axial reciprocating motion work together to improve grinding efficiency and grinding consistency. No manual hand operation is required throughout the process, and the operation is safer.

[0036] In the above embodiments, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
