Description

Technical Field

[0001] This utility model relates to the field of industrial brush equipment, and in particular to a wire welding auxiliary mechanism. Background Technology

[0002] Strips are typically manufactured using a hot rolling process. Before actual use, rust and oxide scale will appear on the surface of the strip, requiring brush rollers to polish the surface. To facilitate disassembly and maintenance, an existing brush roller structure is configured to have multiple brush discs mounted on the roller shaft. Each brush disc includes a brush plate, and the inner side of the brush plate has multiple circumferentially distributed filament holes. A bundle of filaments made of resin material needs to be inserted into the filament holes. The filament bundle includes two strands folded in half radially away from the brush plate.

[0003] The existing method uses wire to secure the two strands, but this method is inefficient and has poor fixing effect. Therefore, the applicant has designed a mechanism that can be used with a hot melt welding machine to fix the two strands through hot melt welding; for example... Figure 4 As shown, the mechanism includes a support shaft located near the hot melt welding machine, with a stepper motor connected to the bottom of the support shaft; two positioning discs that mate vertically are located at the top of the support shaft, and multiple pressure rods that press the corresponding strands together are evenly distributed around the outer periphery of the positioning discs; a support platform for supporting the wire is located near the support shaft; during welding, the welding head of the hot melt welding machine is aligned with one of the wire bundles, the welding head is lowered, and the strands of that bundle are welded and fixed; then the stepper motor drives the support shaft to rotate, so that the next wire bundle is aligned with the welding head, and so on, until each wire bundle is welded and fixed; however, this mechanism has shortcomings when performing hot melt welding.

[0004] Each wire bundle is composed of multiple separate elastic wires. Therefore, when the welding head descends, it will exert a squeezing force on the wire bundle, which can easily cause the multiple wires to spread to both sides or bend and deform upwards, resulting in an unreliable weld.

[0005] Setting up a baffle directly on the support platform can limit the spread of the wires, but the baffle will also restrict the rotation of the next wire bundle to the predetermined position, which will also affect the efficiency and quality of welding. Summary of the Invention

[0006] This utility model provides a wire welding auxiliary mechanism. The positioning rod and the pressure plate are driven to move up and down by the first driving member and the second driving member, respectively, so that the wire bundle can remain stable in the limiting groove during welding and will not spread up or to the sides. After welding is completed, the positioning rod and the pressure plate can be reversed and reset to make room, so that the next wire bundle on the brush can move smoothly to the position corresponding to the welding head for welding and fixing. Thus, while ensuring the welding quality of the wire bundle, the welding efficiency of each wire bundle on the brush is improved.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A wire welding auxiliary mechanism, comprising:

[0009] The positioning assembly includes a pressure plate and a positioning rod arranged sequentially from top to bottom. The top of the positioning rod has two opposing side stops, and a limiting groove is formed between the two side stops to accommodate the wire bundle and to correspond to the position of the welding head.

[0010] The drive assembly includes a first drive member and a second drive member that respectively drive the positioning rod and the pressure plate to move longitudinally.

[0011] The wire welding auxiliary mechanism has a working state and a reset state. When the wire welding auxiliary mechanism is in the working state, the first driving member drives the positioning rod to move upward to approach the wire bundle, and the second driving member drives the pressure plate to move downward to press the wire bundle into the limiting groove, so that the wire bundle remains stable in the limiting groove when welding with the welding head. When the wire welding auxiliary mechanism is in the reset state, the first driving member drives the positioning rod to move downward, and the second driving member drives the pressure plate to move upward, so that the wire bundle comes out of the limiting groove.

[0012] Preferably, the system also includes a base, and the first driving component is a first cylinder mounted on the base. The first cylinder has a first piston rod that extends and retracts longitudinally and is connected to a positioning rod. The first cylinder extends and retracts sensitively and rapidly, and can drive the positioning rod to extend and retract quickly.

[0013] Preferably, the first cylinder has a support plate mounted on its cylinder body, which is spaced apart from the base. The second driving component is a second cylinder mounted on the support plate and offset from the position of the first cylinder. The second cylinder has a second piston rod that extends longitudinally, and a connecting plate is mounted on the second piston rod. The connecting plate has an extension plate that extends toward the positioning rod and is connected to the pressure plate so that the position of the pressure plate corresponds to the position of the top of the positioning rod. The pressure plate needs to be close to the limiting groove to press the wire bundle. The connecting plate can compensate for the distance between the second cylinder and the first cylinder due to the spatial layout, so that the position of the pressure plate corresponds to the position of the limiting groove, thereby stably pressing the wire bundle.

[0014] Preferably, a first guide assembly is installed on the support plate. The first guide assembly includes two support rods symmetrically arranged on the support plate. The top ends of the two support rods are connected to guide blocks. The guide blocks are provided with guide grooves corresponding to the positions of the positioning rods. The positioning rods move longitudinally within the guide grooves, allowing the wire welding aid to switch between the working state and the reset state. The guide grooves on the guide blocks can provide guidance for the positioning rods. In the working state, the upper end of the positioning rod extends beyond the upper end of the guide block. In the reset state, the upper end of the positioning rod retracts into the guide groove, which will not affect the movement of the next wire bundle on the brush to the corresponding welding position.

[0015] Preferably, a second guide assembly is installed on the cylinder body of the second cylinder. The second guide assembly includes a guide plate installed on the cylinder body of the second cylinder. Guide holes are symmetrically opened on the guide plate, and a guide rod connected to the connecting plate is slidably connected in the guide hole. The guide rod cooperates with the guide hole to provide movement guidance for the pressure plate and the connecting plate.

[0016] Preferably, the guide plate is provided with a guide sleeve corresponding to the position of the guide hole, and the guide rod is slidably connected in the guide sleeve; the guide sleeve can extend the guide length of the guide hole, making the extension and retraction of the guide rod smoother.

[0017] Preferably, the extension plate and the pressure plate are connected by screws, and the extension plate is provided with a waist-shaped groove to facilitate screw insertion; the waist-shaped groove has a large installation allowance, which facilitates screw insertion.

[0018] Preferably, the pressure plate is provided with a clearance hole corresponding to the position of the limiting groove and used to avoid the welding head; so that the welding head can pass through the clearance hole to weld the wire bundle.

[0019] The beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0020] The wire welding auxiliary mechanism of this utility model controls the positioning rod and pressure plate to move up and down through the first and second driving components in the driving assembly. During welding, the wire bundle is forced into the limiting groove at the top of the positioning rod. The limiting groove and pressure plate can restrict the wire bundle in all directions, preventing the wire bundle from spreading outward when subjected to the welding head, thus ensuring the welding quality of the wire bundle. After welding is completed, the first and second driving components control the positioning rod and pressure plate to reset in the opposite direction. This allows the welded wire bundle to leave the limiting groove and pressure plate while making room for the next wire bundle to be welded. This allows the next wire bundle on the brush plate to move smoothly to the corresponding position for welding and fixing, avoiding the next wire bundle being blocked by the positioning assembly, thereby improving the welding efficiency of each wire bundle on the brush plate.

Detailed Implementation

[0026] 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.

[0027] 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.

[0028] The specific embodiments of this utility model are as follows:

[0029] like Figure 1-3 As shown, this embodiment provides a wire welding auxiliary mechanism, including:

[0030] The positioning assembly includes a pressure plate 4 and a positioning rod 2 arranged sequentially from top to bottom. The top of the positioning rod 2 has two opposing side stops 21, and a limiting groove 22 is formed between the two side stops 21 for accommodating the wire bundle and corresponding to the position of the welding head 71.

[0031] The drive assembly includes a first drive member and a second drive member that respectively drive the positioning rod 2 and the pressure plate 4 to move longitudinally.

[0032] The wire welding auxiliary mechanism has a working state and a reset state. When the wire welding auxiliary mechanism is in the working state, the first driving member drives the positioning rod 2 to move upward to approach the wire bundle, and the second driving member drives the pressure plate 4 to move downward to press the wire bundle into the limiting groove 22, so that the wire bundle remains stable in the limiting groove 22 when it meets the welding head 71 for welding. After the pressure plate 4 presses the wire bundle into the limiting groove 22, it still acts on the upper end of the wire bundle to prevent the wire bundle from bending upward when the welding head acts on the wire bundle, thus affecting the welding quality. When the wire welding auxiliary mechanism is in the reset state, the first driving member drives the positioning rod 2 to move downward, and the second driving member drives the pressure plate 4 to move upward, so that the wire bundle comes out of the limiting groove 22. This makes room for the next wire bundle to be welded on the brush, so that it can move smoothly to the position corresponding to the welding head 71.

[0033] Furthermore, the installation layout of the positioning component and the drive component is as follows: The wire welding auxiliary mechanism also includes a base 1, and the first drive component is a first cylinder 6 mounted on the base 1. The first cylinder 6 has a first piston rod that extends and retracts longitudinally and is connected to the positioning rod 2; the first cylinder 6 extends and retracts sensitively and rapidly, and can drive the positioning rod 2 to extend and retract quickly; to avoid interference with the first cylinder 6, a support plate 61 that is spaced apart from the base 1 is mounted on the cylinder body of the first cylinder 6, and the second drive component is a second piston rod mounted on the support plate 61 and offset from the position of the first cylinder 6. The cylinder 5 has a second piston rod that extends longitudinally, and a connecting plate 43 is mounted on the second piston rod. The connecting plate 43 has an extension plate 431 that extends toward the positioning rod 2. The extension plate 431 is connected to the pressure plate 4 so that the position of the pressure plate 4 corresponds to the position of the top of the positioning rod 2. When welding the wire bundle, the pressure plate 4 needs to be close to the limiting groove 22 in order to press the wire bundle. The connecting plate 431 can compensate for the distance between the second cylinder 5 and the first cylinder 6 due to the spatial layout, so that the pressure plate 4 corresponds to the position of the limiting groove 22, thereby stably pressing the wire bundle.

[0034] Furthermore, to ensure smooth up-and-down movement of the positioning rod 2, a first guide assembly is installed on the support plate 61. The support plate 61 serves as the mounting carrier for the second cylinder 5 and also as the mounting carrier for the first guide assembly. The first guide assembly includes two support rods 32 symmetrically arranged on the support plate 61. The top ends of the two support rods 32 are connected to guide blocks 3. The guide blocks 3 are provided with guide grooves 31 corresponding to the position of the positioning rod 2. The positioning rod 2 moves longitudinally within the guide grooves 31, allowing the wire welding auxiliary to switch between the working state and the reset state. The guide grooves 31 on the guide blocks 3 can provide guidance for the positioning rod 2. This ensures that when the wire welding auxiliary mechanism is in the working state, the upper end of the positioning rod 2 extends beyond the upper end of the guide block 3. When the wire welding auxiliary mechanism is in the reset state, the upper end of the positioning rod 2 retracts downward into the guide grooves 31, without affecting the movement of the next wire bundle on the brush to the corresponding welding position.

[0035] Furthermore, in order to ensure that the pressure plate 4 moves smoothly up and down without deviation, a second guide assembly is installed on the cylinder body of the second cylinder 5. The second guide assembly includes a guide plate 51 installed on the cylinder body of the second cylinder 5. Guide holes are symmetrically opened on the guide plate 51, and a guide rod 52 connected to the connecting plate 43 is slidably connected in the guide hole. The guide rod 52 cooperates with the guide hole to provide movement guidance for the pressure plate 4 and the connecting plate 43.

[0036] Furthermore, since the thickness of the guide plate 51 is limited, in order to make the sliding of the guide rod 52 more stable, the guide plate 51 is provided with a guide sleeve 53 corresponding to the position of the guide hole, and the guide rod 52 is slidably connected in the guide sleeve 53; the guide sleeve 53 can extend the guide length of the guide hole, making the extension and retraction of the guide rod 52 smoother.

[0037] Furthermore, the extension plate 431 is connected to the pressure plate 4 by screws. In order to facilitate the adjustment of the area of ​​the pressure plate 4 pressing the wire bundle, the extension plate 431 is provided with a waist-shaped groove 432 to facilitate the screw insertion. The waist-shaped groove 432 has a large installation margin, which facilitates the screw insertion. At the same time, the screw can also adjust the position of the pressure plate 4 by changing the installation position of the screw in the waist-shaped groove 432, so that the pressure plate 4 maintains a reasonable working area on the wire bundle.

[0038] Furthermore, in order to stably compress the wire bundle when the welding head 71 is working, the pressure plate 4 will press the upper surface of the wire bundle. However, completely pressing the upper surface of the wire bundle will cause the welding head 71 to interfere with the pressure plate 4. Therefore, in this embodiment, the pressure plate 4 is provided with a relief hole 41 that corresponds to the position of the limiting groove 22 and is used to avoid the welding head. The relief hole 41 can provide welding relief space to avoid interference between the welding head 71 and the pressure plate 4, so that the welding head 71 can pass through the relief hole 41 to weld the wire bundle.

[0039] 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.
