Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, specifically to a grooving limiter for angle grinders. Background Technology

[0002] Currently, most families install their kitchen sinks in a countertop style during home renovations. The edge of the countertop sink is fitted into the countertop, combining the advantages of both top-mount and undermount sinks. It is easy to clean and sturdy.

[0003] However, to install the basin into the countertop, a groove needs to be cut into the countertop on-site according to the size of the basin so that the edge of the basin can be embedded into the countertop.

[0004] In existing technologies, traditional cutting and grooving methods involve a groove in the middle of the limiting and adjusting structure of the cutting machine. The cutting blade is placed in the groove, and the adjusting arm is locked in the middle of the cutting blade. During grooving and cutting, the entire adjusting arm is in contact with the table surface. A large amount of dust is generated during the cutting process. Because the adjusting arm and the table surface form a semi-enclosed space, the dust accumulates along the cutting line during grooving and cutting and cannot be discharged, causing the dust to cover the cutting line and preventing normal cutting along the line. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues of traditional cutting and grooving methods, the limiting and depth-adjusting structure of the cutting machine has a groove in the middle. The cutting blade is placed in the groove, and the adjusting arm is locked in the middle of the cutting blade. During grooving and cutting, the entire adjusting arm is in contact with the table surface, generating a large amount of dust. Because the adjusting arm and the table surface form a semi-enclosed space, the dust accumulates along the cutting line and cannot be discharged, causing the dust to cover the cutting line and preventing normal cutting. This utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a grooving limiter for angle grinders. It is installed on the mounting shaft of the angle grinder by a cover, and the sliding adjustment arm adjusts the distance between the moving end and the stationary end, thereby controlling the cutting depth of the cutting blade. The tail groove, dust discharge groove and cutting blade are axially arranged to form a dust discharge channel, which achieves the effect of efficient discharge of cutting dust along the cutting groove direction under centrifugal force. It solves the problem of existing technology where dust covers the cutting line due to the limitation of the adjustment arm, resulting in the inability to cut normally.

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural diagram of an embodiment of a slotting limiter for angle grinders, including:

[0034] Please see Figures 1-6 This embodiment of a grooving limiter for an angle grinder includes a cover 1 and an adjusting arm 2. The cover 1 is connected to the mounting shaft of the angle grinder. A stationary end 11 is provided on the cover 1, and a moving end 21 is provided on the adjusting arm 2. The stationary end 11 is located at the lowest end of the cover 1, and the moving end 21 is located at the bottom end of the adjusting arm 2. Both the stationary end 11 and the moving end 21 are smooth cylindrical shapes. The adjusting arm 2 is movably connected to the cover 1, and the adjusting arm 2 is located outside the cover 1. The position of the stationary end 11 is fixed. The distance between the moving end 21 and the stationary end 11 is adjusted by adjusting the adjusting arm 2. During use, both the moving end 21 and the stationary end 11 are in contact with the table surface. The cutting depth is adjusted by changing the distance between the moving end 21 and the stationary end 11. With the surfaces in contact, the cutting blade can cut grooves of consistent depth. The cylindrical moving end 21 and stationary end 11 can reduce the coefficient of friction with the table surface, thus reducing the pushing and pulling force. A dust removal groove 12 is opened on the cover 1, which is opened through the middle of the moving end 21 of the cover 1. A tail groove 22 is opened at the bottom of the adjusting arm 2. The tail groove 22, the dust removal groove 12 and the cutting blade are axially arranged to form a dust removal channel. Under the centrifugal force of the cutting blade, the dust generated during cutting can be discharged along the direction of the cutting groove. The tail groove 22 and the dust removal groove 12 are respectively set on the adjusting arm 2 and the cover 1. The cutting depth can be adjusted through the same structure, while the dust generated during cutting is discharged along the dust removal channel. At the same time, the tail groove 22 facilitates the observation of the cutting groove and real-time monitoring of the cutting groove depth.

[0035] It is worth noting that, specifically, a dust discharge groove 12 is provided on the cover 1, and a tail groove 22 is provided at the bottom end of the adjusting arm 2.

[0036] Next, specifically, the adjusting arm 2 is provided with a connecting hole 3. The connecting hole 3 is connected to the cover 1 by a screw. The screw is movably positioned between the screw and the connecting hole 3 and passes through the connecting hole 3 to be screwed to the cover 1. By turning the screw to adjust the tightness, the adjusting arm 2 can slide, adjusting the distance between the moving end 21 and the stationary end 11, thereby adjusting the cutting depth.

[0037] Specifically, a locking pin 4 is screwed onto the cover 1. The locking pin 4 is placed at the opening of the fixing ring of the cover 1. One end of the locking pin 4 passes through the fixing ring and is screwed onto the other end. Tightening the locking pin 4 can adjust the inner diameter of the fixing ring, thereby locking the cover 1 onto the mounting shaft of the angle grinder. This facilitates the fixing and disassembly of the cover 1, improving ease of use. Multiple limiting blocks 41 are arranged in a ring array on the inner side of the cover 1. The limiting blocks 41 are placed inside the fixing ring of the cover 1 and cooperate with the limiting groove on the mounting shaft. The cover 1 achieves three-dimensional locking by engaging the limiting blocks 41 on the inner side with the limiting groove of the mounting shaft of the angle grinder and cooperating with the locking pin 4, thus avoiding the problem of positioning displacement caused by high-frequency vibration of the angle grinder.

[0038] Furthermore, specifically, the surfaces of the cover 1 and the adjusting arm 2 that come into contact with each other are provided with a plurality of first limiting teeth 5 at equal intervals, and the adjusting arm 2 is provided with a plurality of second limiting teeth 51 at equal intervals to cooperate with the first limiting teeth 5. The adjusting arm 2 and the cover 1 are connected by screws, and the cover 1 and the adjusting arm 2 can also be connected by hinges. By rotating the adjusting arm 2 and hinged it to the cover 1, the distance between the stationary end 11 and the moving end 21 can also be adjusted.

[0039] The surfaces of the cover 1 and the adjusting arm 2 that are in contact with each other are provided with a plurality of first limiting teeth 5 at equal intervals. The adjusting arm 2 is provided with a plurality of second limiting teeth 51 at equal intervals to cooperate with the first limiting teeth 5. When the screw is tightened, the first limiting teeth 5 and the second limiting teeth 51 are engaged and interlocked to increase the stability of the connection between the adjusting arm 2 and the cover 1.

[0040] It is worth noting that, specifically, the adjusting arm 2 is provided with a scale line 6, which is proportional to the tooth pitch of the first limiting tooth 5 and the second limiting tooth 51. The cutting depth can be finely adjusted by adjusting the scale line 6 of the adjusting arm 2 to reduce the deviation of the cutting depth.

[0041] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0042] Combination Figures 1-6 The specific usage process of the grooving limiter for angle grinders in this embodiment is as follows:

[0043] 1. First, put the cover 1 on the mounting shaft of the angle grinder and fix it by tightening the locking pin 4. Then, install the cutting disc on the angle grinder and slide the adjusting arm 2 according to the thickness of the edge of the basin.

[0044] 2. Then adjust the distance between the moving end 21 and the stationary end 11 to adjust the cutting depth of the cutting blade, and tighten the screws to fix the adjusting arm 2 and the cover 1.

[0045] 3. After both the moving end 21 and the stationary end 11 are in contact with the table surface, start the angle grinder to cut downwards and slowly push the angle grinder so that the cutting blade cuts the table surface, and the operation is completed.
