Description

Technical Field

[0001] This utility model relates to the field of surface processing equipment technology, and in particular to a polishing and wire drawing device. Background Technology

[0002] With the continuous progress and development of science and technology, the equipment and instruments used in production and daily life are also constantly being updated and iterated. Among them, many parts require high precision and surface roughness to meet people's needs. Some daily necessities and handicrafts, although they do not require high precision, need to be polished or wire-drawn to facilitate subsequent processing (such as painting, assembly, etc.).

[0003] Currently, parts requiring high precision are ground using grinding machines, while parts requiring lower precision are ground using grinding wheels or angle grinders. Although the latter can meet the need for quick removal of excess material, grinding wheels are usually fixed and cannot be moved outdoors or to places without mains power, resulting in strong limitations in the operating scenarios and insufficient flexibility and cost-effectiveness.

[0004] Therefore, there is an urgent need for a polishing and wire drawing tool to solve the problems existing in the current technology. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0035] Combination Figures 1 to 3As shown, this utility model provides a polishing and wire drawing device, including a housing 1, a first shaft 2, a second shaft 3, a transmission pair 4, and a grinding wheel 5. The housing 1 has a first channel 11 and a second channel 12 inside. One end of the first channel 11 is connected to the second channel 12, and the first channel 11 extends along the axial direction of the housing 1. The length extension direction of the second channel 12 is perpendicular to the first channel 11. The first shaft 2 is rotatably disposed within the first channel 11, with one end of the first shaft 2 being drive-connected to the second shaft 3, and the other end of the first shaft 2 being drive-connected to a rotary drive component. The second shaft 3 is rotatably disposed within the second channel 12, and both ends of the second shaft 3 are drive-connected to the grinding wheel 5. The transmission pair 4 is disposed within the housing 1 and is used to drive the first end of the first shaft 2 and the second shaft 3 together.

[0036] The polishing and wire drawing tool provided in this embodiment has a simple structure and compact connections between components. In practical use, a rotary drive component can be connected to the other end of the second shaft 3. This allows the rotational force to be transmitted to the grinding wheel 5 via the second shaft 3, transmission pair 4, and first shaft 2, enabling the grinding wheel 5 to roll and complete the grinding of the workpiece. When not in use, this tool can be easily carried outdoors or to places without mains power, thus breaking site limitations and allowing for use in various scenarios. For example, when the grinding wheel 5 is a polishing wheel or a wire drawing wheel, this tool is suitable for various occasions such as weld polishing, sharp angle chamfering, stainless steel plate wire drawing, and polishing and wire drawing of corridor handrails, effectively improving the flexibility and cost-effectiveness of use, and greatly increasing work efficiency.

[0037] In this embodiment, reference Figure 1 As shown, the other end of the first shaft 2 is also provided with a hexagonal transmission handle 21. The hexagonal transmission handle 21 is used to drive the rotary drive component. With the setting of the hexagonal transmission handle 21, the rotary drive component can be used with a hand drill, air drill or electric wrench and through an adapter in the absence of power, which facilitates the carrying of the rotary drive component and further reduces the pressure on the operator.

[0038] In this embodiment, a dustproof component 6 is also connected to the outer casing 1. The dustproof component 6 includes a dust cover 61 and fasteners 62. The dust cover 61 is shaped to match the outer circumferential surface of the grinding wheel 5 and is positioned across the grinding wheel 5 at intervals. The fasteners 62 are used to securely connect the dust cover 61 to the outer casing 1. The dust cover 61 prevents grinding and dust from flying from the workpiece surface during polishing, thus protecting the user.

[0039] Preferably, the dust cover 61 is a semi-circular shell, which allows the dust cover 61 to maximize the area it can cover without obstructing the contact between the grinding wheel 5 and the workpiece surface, thereby maximizing the protection.

[0040] Optionally, in this embodiment, the fastener 62 includes a clamp with a semi-circular ring structure. After the main body of the clamp is fitted onto the outer shell 1, the lugs at both ends of the main body can be fixedly connected to the dust cover 61 by threaded fasteners 62 (e.g., screws), thereby stably securing the dust cover 61 to the outer shell 1. This fixing method is convenient to install, reliable in fixing, and flexible in disassembly, meeting the needs of rapid on-site assembly and disassembly; moreover, the structure is simple, ensuring that the overall construction of the tool is compact and lightweight.

[0041] In this embodiment, an operating handle 7 is also connected to the outer shell 1, so that the operator can use one hand to hold the operating handle 7 to improve the stability of the tool during the polishing and wire drawing process, reduce the shaking and vibration of the grinding wheel 5 on the surface of the workpiece, and enable the grinding wheel 5 to maintain a close fit with the surface of the workpiece, thereby ensuring the surface processing quality, improving work efficiency, and reducing the scrap rate of the workpiece.

[0042] Specifically, refer to Figure 2 As shown, the operating handle 7 includes a handle housing 71, a connecting bolt 72, and a locking nut 73. The handle housing 71 has a third channel along its axis inside. The housing 71 has a mounting through hole 13, which communicates with the first channel 11. The connecting bolt 72 has a second external thread section 721, which passes through the third channel and the mounting through hole 13 in sequence and is threadedly connected to the locking nut 73 fixedly installed in the housing 1. The handle housing 71 is rotatably connected to the connecting bolt 72, and the end of the connecting bolt 72 can abut against the opening edge surface of the third channel to axially limit the handle housing 71.

[0043] The operating handle 7 provided in this embodiment has a simple structure, strong connection safety and stability, and the locking nut 73 can fix the connecting bolt 72 to the outer shell 1, allowing the operator to apply forces in different directions to the outer shell 1 through the handle shell 71 and the connecting bolt 72, flexibly adjusting the angle between the grinding wheel 5 and the workpiece surface to meet the processing needs of different parts such as welds, chamfers, and curved surfaces. In addition, since the handle shell 71 and the connecting bolt 72 are rotatably connected, that is, after the connecting bolt 72 and the locking nut 73 are tightened, the handle shell 71 still has room to move freely, allowing the handle shell 71 to rotate 360° around the central axis of the connecting bolt 72, making it more convenient and flexible to use, automatically changing the angle according to the body, and not tiring even after prolonged use.

[0044] Furthermore, in this embodiment, the outer shell 1 has two mounting through holes 13 spaced apart along its circumferential direction, and a locking nut 73 is fixedly embedded in each mounting through hole 13. The connecting bolt 72 can be selectively threaded to any one of the locking nuts 73 to adjust the mounting position of the handle shell 71 and the connecting bolt 72 on the outer shell 1. This allows the handle shell 71 to form two different assembly positions with the outer shell 1 through the connecting bolt 72, thereby flexibly adjusting the operator's grip posture and adapting to the processing needs of the grinding wheel 5 for different parts of the workpiece (such as internal corners, welds, and flat surfaces). At the same time, it expands the operating angle range of the tool and improves ease of use.

[0045] In this embodiment, reference Figure 3 As shown, the transmission pair 4 includes a first transmission gear 41 and a second transmission gear 42. The first transmission gear 41 is meshed with the second transmission gear 42. The first transmission gear 41 is fixedly connected to one end of the first shaft 2 and is aligned with the central axis of the first shaft 2. The second transmission gear 42 is fixedly sleeved on the outer circumference of the second shaft 3 and is aligned with the central axis of the second shaft 3. This configuration allows the rotational torque of the first shaft 2 to be precisely transmitted to the second shaft 3 via gear meshing, while simultaneously enabling a 90° switch in rotation direction. This design is not only simple in structure but also provides precise torque transmission, allowing the operator to better control the grinding force, avoiding insufficient grinding and reducing operational difficulty.

[0046] In a preferred embodiment, both the first transmission gear 41 and the second transmission gear 42 are right-angle bevel gears, which effectively ensures the meshing of the tooth surfaces of the first transmission gear 41 and the second transmission gear 42, making torque transmission more direct and reliable. Preferably, the first transmission gear 41 and the second transmission gear 42 are made of high-strength carbon steel gears, which can reduce the degree of deformation caused by stress or heat after long-term use and extend their service life.

[0047] Of course, in other parallel embodiments, the first transmission gear 41 and the second transmission gear 42 may also be selected from combinations such as spiral bevel gears and quasi-hyperboloid bevel gears, and this utility model does not limit this.

[0048] Optionally, in this embodiment, a silent bearing 8 is also provided between the first shaft 2 and the inner wall of the first channel 11; the portions of the second shaft 3 located at both ends of the second transmission gear 42 are also provided with silent bearings 8 between them and the inner wall of the second channel 12. The use of silent bearings 8 reduces the shaking and vibration during the rotation of the first shaft 2 and the second shaft 3, making their rotation more stable and the tool smoother to use. While ensuring concentricity, it also reduces noise and heat generated during use, thereby improving the operator's experience.

[0049] In this embodiment, the grinding wheel 5 specifically includes a roller 51, a centering bushing 52, and a fastening nut 53. The roller 51 has a first shaft hole, and the centering bushing 52 has a second shaft hole. During installation, the shaft body of the centering bushing 52 can be inserted into one end of the first shaft hole, while the head of the centering bushing 52 is pressed against the side surface of the roller 51. At this time, the first shaft hole and the second shaft hole can maintain a coaxial positional relationship. In addition, the end of the second shaft 3 also has a first external thread section 31. When assembling the second shaft 3 with the grinding wheel 5, the first external thread section 31 of the second shaft 3 can be inserted into the roller 51 from the other end of the first shaft hole and exit through the second shaft hole. At this time, the first external thread section 31 can protrude from the head of the centering bushing 52 to the outside. Then, the fastening nut 53 is threadedly connected to the first external thread section 31 and pressed tightly against the side surface of the centering bushing 52, thereby completing the fixed assembly of the grinding wheel 5 and the second shaft 3.

[0050] The grinding wheel 5 provided in this embodiment has a simple structure, reliable installation with the second shaft 3, and high tightness, making it suitable for most polishing and wire drawing scenarios. Moreover, the grinding wheel 5 operates stably, preventing the roller 51 from slipping during polishing and wire drawing, and ensuring the concentricity of the roller 51 with the second shaft 3 during operation. This avoids the drawbacks of the roller 51 jumping during operation, such as difficult operation and rough grinding marks.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
