Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip grinding, and in particular to a wire clamping mechanism. Background Technology
[0002] Strip steel is typically manufactured using a hot-rolling process. Before actual use, the surface of the strip steel will develop rust, oxide scale, etc., requiring brushing and polishing of the surface using a brush roller. To facilitate disassembly and maintenance, an existing brush roller structure is configured with multiple grinding brush discs mounted on a roller shaft. The grinding brush disc includes an annular brush disc with an inner hole. The inner side of the brush disc has multiple circumferentially distributed wire holes. Multiple parallel pre-prepared wires made of polymer material are inserted into the wire holes. The wires are then cut to a predetermined length by a cutter to form truncated wires inserted into the wire holes. The truncated wires are divided into two strands located on both sides of the brush disc. The two strands are folded in half along the radial direction away from the brush disc and then fixed to form a wire bundle for grinding the strip steel.
[0003] Ideally, the width of the wire hole should match the width of the multiple parallel pre-stranded wires. However, in reality, the width of the wire hole should be slightly smaller than the width of the pre-stranded wires. This prevents the wire bundle from wobbling when it is formed and used to polish the strip, ensuring a good polishing effect. However, a smaller wire hole will create greater resistance when a larger pre-stranded wire is inserted, resulting in low wire threading efficiency. Furthermore, since the wires are made of polymer materials and are elastic, they are difficult to thread through by forcibly pressing them into place.
[0004] Therefore, the applicant envisioned a threading method in which a small section of the prepared filament is first passed through the filament hole of the brush plate to form a traction section. Then, the filament of a predetermined length is pulled into place by pulling the traction section in one go. After that, the filament is cut by a cutter to form a cut filament that is threaded in the filament hole, thereby improving the threading efficiency. However, since the traction section is relatively short and the filament is made of polymer material with a relatively smooth surface, it is difficult to pull it directly. Therefore, a filament clamping mechanism that can pull and release the traction section is needed to clamp and pull the traction section to ensure the threading efficiency. Summary of the Invention
[0005] This utility model provides a wire clamping mechanism. Through the cooperation between the wire clamping drive and the wire clamping assembly, the wire clamping assembly can drag the traction section to the corresponding position after clamping the traction section of the prepared wire, so that the prepared wire can be quickly threaded into the wire hole of the brush plate, thereby improving the wire threading efficiency.
[0006] The technical solution of this utility model is implemented as follows:
[0007] A wire clamping mechanism, comprising:
[0008] The wire clamping assembly includes a base, on which are provided opposing first and second wire clamping members. At least one of the first and second wire clamping members is provided with a clamping drive.

[0009] The wire clamping drive unit, connected to the base, can drive the wire clamping assembly to move along the threading direction of the prepared wire to move closer to or away from the traction section on the brush side.
[0010] In operation, the wire clamping drive first drives the wire clamping assembly to approach the brush disk, so that the traction section is between the first wire clamping member and the second wire clamping member. Then, the clamping drive causes the first wire clamping member and / or the second wire clamping member to move to clamp the traction section. After that, the wire clamping drive drives the wire clamping assembly to move away from the brush disk so that the prepared wire is pulled into place in the wire hole of the brush disk.

Detailed Implementation
[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0030] like Figure 1-6 As shown, the specific embodiments of this utility model are as follows:
[0031] This embodiment provides a wire clamping mechanism, including:
[0032] The wire clamping assembly includes a base 4, on which a first wire clamping member and a second wire clamping member are provided opposite each other. At least one of the first wire clamping member and the second wire clamping member is provided with a clamping drive member. The clamping drive member can drive the corresponding first wire clamping member and / or the second wire clamping member to clamp or release the traction section 71 formed on one side of the brush disk 6 after the prepared wire 7 passes through the wire hole of the brush disk 6.
[0033] The wire clamping drive is connected to the base 4 and can drive the wire clamping assembly to move along the threading direction of the prepared wire 7 to move closer to or away from the traction section 71 on the side of the brush 6.
[0034] In operation, the wire clamping drive first drives the wire clamping assembly to approach the brush disk 6, so that the traction section 71 is between the first wire clamping member and the second wire clamping member. Then, the clamping drive causes the first wire clamping member and / or the second wire clamping member to move to clamp the traction section 71. After that, the wire clamping drive drives the wire clamping assembly to move away from the brush disk 6, so that the wire clamping assembly directly drags the traction section 71 along the threading direction of the prepared wire 7, so that the prepared wire 7 is pulled into place in the wire hole of the brush disk 6.
[0035] Furthermore, a clamping drive can be connected to either the first or the second wire clamping component, or both the first and the second wire clamping components can be connected to clamping drive components. In this way, when the corresponding clamping drive components are working, they can both drive the first and the second wire clamping components to clamp or loosen the traction section. In this embodiment, only one clamping drive component is used for explanation. Specifically, in this embodiment, the first wire clamping component is a wire clamping block 1, the second wire clamping component is a wire clamping rod 2, and the clamping drive component is a clamping cylinder 11 connected to the wire clamping block 1 and driving the wire clamping block 1 away from or close to the wire clamping rod 2.
[0036] Furthermore, in order to prevent the traction section 71 from deforming under force and affecting the clamping effect when the clamping block 1 and the clamping rod 2 clamp the traction section 71, the clamping block 1 is provided with a clamping part for cooperating with the clamping rod 2 and an extension part 15 spaced apart from the clamping part. A strip groove 3 for accommodating the traction section 71 is formed between the extension part 15 and the clamping part; so that the traction section 71 remains stable in the strip groove 3 when it is clamped by the clamping assembly.
[0037] Furthermore, the clamping rod 2 and the extension 15 are located on the same side. To avoid interference between the clamping rod 2 and the extension, the extension 15 is provided with a through groove 16 that matches the clamping rod 2. The clamping rod 2 is inserted into the through groove 16. When the piston rod of the clamping cylinder 11 extends, the clamping block 1 moves away from the clamping rod 2, and the head of the clamping rod 2 retracts into the through groove 16, so that the traction section 71 enters the strip groove 3. When the piston rod of the clamping cylinder 11 retracts, the clamping block 1 approaches the clamping rod 2, and the head of the clamping rod 2 enters the limiting groove to clamp the traction section 71 located in the strip groove 3. This design ensures that the clamping block 1, while providing the extension 15, ensures that the clamping rod 2 does not interfere with the extension 15 and can cooperate normally with the clamping part.
[0038] Furthermore, the clamping cylinder 11 is installed as follows: a mounting plate 12 is provided on the base 4, and the clamping cylinder 11 and the clamping rod 2 are mounted on the mounting plate 12; a guide structure is provided between the mounting plate 12 and the clamping block 1, the guide structure includes a guide rod 13 mounted on the clamping block 1, and a guide hole 14 matching the guide rod 13 is provided on the mounting plate 12, the guide rod 13 is slidably connected in the guide hole 14; in this embodiment, there are two guide holes 14 on the mounting plate 12, the number of guide rods 13 matches the number of guide holes 14, and the guide rods 13 slide in the guide holes, making the clamping block 1 move more smoothly.
[0039] Furthermore, in addition to the guide structure, the base 4 is provided with a guide groove 41 that matches the wire clamping block 1 and extends along the direction of movement of the wire clamping block 1. The wire clamping block 1 is slidably connected in the guide groove 41, so that the wire clamping block 1 has a dual guiding effect when it moves, ensuring that the wire clamping block 1 moves more smoothly.
[0040] Furthermore, in order to enable the wire clamping assembly to quickly move away from the brush plate 6 after clamping the traction section 71, the wire clamping drive in this embodiment is a wire clamping cylinder 5 set on the side of the base 4 facing away from the wire clamping assembly; the wire clamping cylinder 5 extends and retracts sensitively and quickly, which can meet the usage requirements of driving the wire clamping assembly to quickly approach or move away from the brush plate 6.
[0041] Furthermore, the head of the clamping rod 2 faces the clamping part to clamp the traction section 71. Compared to the flat head of the clamping rod 2, the sharper head of the clamping rod 2 can better clamp the traction section 71. Therefore, in this embodiment, the head of the clamping rod 2 has a chamfered clamping blade 21. The clamping blade 21 can better clamp the traction section 21 and prevent the traction section 71 from loosening between the clamping rod 2 and the clamping part when the clamping cylinder 5 drives the clamping assembly away from the brush plate 6.
[0042] Furthermore, the width of the pre-stranded wires 7 inserted into the wire holes of different diameters is also different. Therefore, the movable length of the clamping block 1 should be within a reasonable range. If the movable length of the clamping block 1 is too short, it will be difficult to clamp the traction section 71 of the pre-stranded wires 7. If the movable length of the clamping block 1 is too long, it will cause the traction section 71 to be overloaded, causing the traction section 71 to deform or even be damaged. Therefore, in this embodiment, the extension range of the piston rod of the clamping cylinder 11 is 1mm-5mm. The extension range of the piston rod of the clamping cylinder 11 is the movable range of the clamping block 1, so that pre-stranded wires 7 of different widths can be reasonably clamped by the clamping block 1 and the clamping rod 2.
[0043] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
