Description

Technical Field

[0001] The utility model relates to the technical field of angle grinder accessories, in particular to a functional adapter for an angle grinder. Background Art

[0002] In modern industry and various processing fields, angle grinders are a very common general-purpose power tool. With their high-speed rotating grinding wheels or cutting discs, they play a key role in many scenarios such as metal processing, wood cutting and stone grinding. However, with the increasing diversification and refinement of processing technology requirements, the limitations of traditional angle grinders have become increasingly prominent. Its functions are relatively single, and it can only be adapted to specific types of grinding wheels and cutting discs for routine operations. It is not directly compatible with tools that require vertical support and fine control such as trimmers and engraving machines. This means that if users want to carry out multi-functional processing business, they have to purchase special equipment (trimmers, engraving machines) separately. This not only greatly increases the cost of equipment procurement, but also greatly limits the operation scenarios and reduces work efficiency due to the different use requirements of various equipment.

[0003] From the perspective of adapters, most of the adapters currently on the market for expanding the functions of angle grinders basically use quick connectors to directly connect the tools of trimmers and engraving machines for use. The most prominent problem is that these adapters generally lack an effective support structure. After the tool is installed, since there is no design for the supporting bottom surface, the tool is very likely to be displaced or shaken during the suspended operation due to the vibration generated during the operation. This unstable operating state, on the one hand, will cause the surface of the workpiece to be rough, seriously affecting the processing quality; on the other hand, in extreme cases, it may even cause safety accidents and pose a threat to the personal safety of the operator.

[0004] In summary, developing an adapter device that can effectively solve the problem of single function of angle grinders and has a stable support structure has become a technical problem that needs to be solved urgently in the industry. This patented technical solution is proposed based on this background, aiming to fill the market gap and provide a reliable solution for the multifunctional application of angle grinders. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a functional adapter for an angle grinder.

[0006] The technical solution adopted by the utility model is: a functional adapter for an angle grinder, comprising:

[0007] A sleeve, wherein a pre-tightening ring 1 is extended from the upper end of the sleeve, a convex portion is arranged on the inner wall of the pre-tightening ring 1, and a tightening mechanism 1 is provided on the pre-tightening ring 1 for radially tightening or loosening the pre-tightening ring;

[0008] A base coaxially mounted with the sleeve, the base comprising a second pre-tightening ring and a support plate at the bottom of the second pre-tightening ring, the second pre-tightening ring is provided with a second loosening mechanism for radially tightening or loosening the second pre-tightening ring, and the second pre-tightening ring is axially fixedly connected with the sleeve through the second loosening mechanism;

[0009] A through hole for the tool to extend out is arranged in the support plate, and the bottom surface of the support plate has a support bottom surface which is perpendicular to the axis of the sleeve.

[0010] Furthermore, the base is adjusted up and down relative to the sleeve to adapt to different tools or meet different processing depth requirements.

[0011] Furthermore, the raised portion of the preload ring 1 is a semicircular raised portion adapted to the annular groove of the output shaft housing of the angle grinder.

[0012] Furthermore, both the tensioning mechanism 1 and the tensioning mechanism 2 are open clamps with elastic deformation capabilities, and fixing steps are provided on both sides of the opening of the open clamps. Fixing holes for fixing with fastening bolts are provided on the fixing steps, and radial winding or loosening is achieved by rotating the fastening bolts.

[0013] Furthermore, the fixing hole of the fixing step on one side of the open clamping ring is a hexagonal hole.

[0014] Furthermore, a disassembly notch is provided at the bottom of the sleeve.

[0015] Furthermore, a chip removal opening is provided on the side wall of the second preload ring.

[0016] Furthermore, a visible notch is provided on the side wall of the second pre-tightening ring.

[0017] The beneficial effects of the utility model are:

[0018] 1. Reduce the use cost and expand the use function: users no longer need to purchase additional special equipment such as trimmers and engraving machines to achieve multi-functional processing. Just by installing this adapter, the angle grinder can be directly converted into a device that can use trimmer or engraving machine tools, which greatly saves the equipment procurement cost and effectively broadens the functional range of the angle grinder, so that one device can meet multiple processing needs, significantly improves the comprehensive utilization rate of the equipment, breaks the constraints of the previous operation scenarios caused by functional limitations, and improves work efficiency.

[0019] 2. Improve processing quality. The bottom surface of the support plate is perpendicular to the axis of the sleeve, providing a stable support bottom surface for the tool, changing the unstable state of the tool suspended in the traditional adapter. During the processing, this stable support effectively reduces the vibration of the tool, allowing the tool to accurately process the workpiece, thereby significantly improving the surface quality of the workpiece, and the surface of the workpiece is smoother and finer, greatly improving the product quality.

[0020] 3. Improve the safety of use. The stable support structure reduces the risk of safety accidents caused by tool vibration, displacement or shaking. During use, operators do not need to worry about accidental injuries that may be caused by unstable equipment, which improves the safety of use.

[0021] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] The utility model provides a functional adapter for an angle grinder.

[0032] In this embodiment, refer to Figure 1-6 , the angle grinder function adapter, including:

[0033] A sleeve 1, a pre-tightening ring 2 extending from the upper end of the sleeve 1, a protrusion 3 being arranged on the inner wall of the pre-tightening ring 2, and a tightening mechanism 1 for radially tightening or loosening the pre-tightening ring;

[0034] A base 4 coaxially mounted with the sleeve, the base 4 comprising a pre-tightening ring 2 5 and a support plate 6 at the bottom of the pre-tightening ring 2, the pre-tightening ring 2 5 is provided with a loosening mechanism 2 for radially tightening or loosening the pre-tightening ring 2, and the pre-tightening ring 2 is axially fixedly connected to the sleeve through the loosening mechanism 2;

[0035] The support plate is provided with a through hole 7 for the tool to extend out, and the bottom surface of the support plate has a support bottom surface 8 which is perpendicular to the axis of the sleeve.

[0036] In the above technical solution, the preload ring 1 uses the tensioning mechanism 1 to fasten the sleeve to the head of the angle grinder, and the raised portion is adapted to be connected with the annular groove of the output shaft housing of the angle grinder to increase the stability of the connection. The preload ring 2 is axially fixed to the sleeve by the tensioning mechanism 2, and the length of the two can be achieved by adjusting the depth of the preload ring 2 of the base inserted into the sleeve to adapt to different tool lengths and working conditions. The through hole of the support plate is used for the tool to extend, and the vertical support bottom surface provides a stable support plane for the tool during processing, so that the angle grinder can be equipped with the tools of the trimmer and engraving machine to operate, realizing the functions of the trimmer and engraving machine, thereby broadening the functions of the angle grinder.

[0037] Furthermore, the base is adjusted up and down relative to the sleeve to adapt to different tools or meet different processing depth requirements.

[0038] By loosening the tensioning mechanism, the connection length between the base and the sleeve can be adjusted to adapt to different tools or different processing depth requirements to meet different processing needs.

[0039] Specifically, the raised portion of the preload ring 1 is a semicircular raised portion that matches the annular groove 10 of the output shaft housing 9 of the angle grinder.

[0040] In this embodiment, the semicircular protrusion of the preload ring fits into the annular groove of the output shaft housing of the angle grinder. When the preload ring is tightened by the tensioning mechanism, the protrusion is embedded in the groove to form a tight fit, thereby limiting the relative displacement between the sleeve and the output shaft of the angle grinder and ensuring the stability of the connection during high-speed operation.

[0041] Specifically, the tensioning mechanism 1 and the tensioning mechanism 2 are both open clamps with elastic deformation capabilities. Fixed steps 12 are provided on both sides of the opening 11 of the open clamp. Fixed holes 13 for fixing with fastening bolts 14 are provided on the fixed steps 12. Radial winding or loosening is achieved by rotating the fastening bolts 14.

[0042] In this embodiment, the open clamping ring has elastic deformation capability, and fixing holes are arranged on the fixing steps on both sides of the opening. When the fastening bolts are rotated, the tightening or loosening of the bolts drives the opening spacing of the open clamping ring to change, thereby realizing radial winding or loosening of the pre-tightening ring to achieve the purpose of tightening or disassembly.

[0043] Specifically, the fixing hole of the fixing step on one side of the open clamping ring is a hexagonal hole 15.

[0044] In this embodiment, the hexagonal hole can prevent the fastening bolt from slipping during the tightening process, facilitate accurate operation, and improve installation and disassembly efficiency. The hexagonal hole cooperates closely with the corresponding tool, and the operation is more stable.

[0045] Specifically, a disassembly notch 16 is provided at the bottom of the sleeve.

[0046] In this embodiment, the disassembly and assembly notch at the bottom of the sleeve provides a force point for the operator. When installing or removing the tool, a tool such as a pry bar can be used to insert into the disassembly and assembly notch to install or separate the tool (the tool is connected to the output end of the angle grinder through a quick connector for use).

[0047] Specifically, a chip removal opening 17 is provided on the side wall of the second preload ring.

[0048] In this embodiment, when debris is generated during tool processing, the chip removal openings on the two side walls of the preload ring utilize the airflow generated during processing and the movement of the debris itself to discharge the debris from the chip removal openings, thereby keeping the interior of the adapter and the processing area clean and reducing the adverse effects of the debris on the tool and internal parts of the adapter.

[0049] Specifically, a visible notch 18 is further provided on the side wall of the second pre-tightening ring.

[0050] In this embodiment, through the visible notches on the two side walls of the preload ring, the operator can directly observe whether the tool has abnormal shaking during the processing without removing the adapter, so as to take timely measures to ensure the smooth progress of the processing.

[0051] How to use the adapter

[0052] 1. Install the tool: Connect the tool used for the trimmer or engraving machine to the output end of the angle grinder through a quick connector (you can use existing products and purchase them directly).

[0053] 2. Install the adapter:

[0054] Put the sleeve on the head of the angle grinder, align the raised part of the preload ring 1 with the annular groove of the output shaft housing of the angle grinder, and firmly fix the sleeve on the head of the angle grinder through the tightening mechanism 1 (such as tightening the fastening bolts on the open clamping ring).

[0055] 3. Coaxially sleeve the second preload ring of the base onto the sleeve, and axially fix the second preload ring to the sleeve through the second tensioning mechanism (similarly operate the fastening bolts on the open clamping ring).

[0056] 4. Perform processing: Turn on the angle grinder and operate according to the processing requirements. At this time, the supporting bottom surface of the support plate provides stable support for the tool to ensure processing accuracy and safety.

[0057] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
