Description

Technical Field

[0001] This utility model relates to circular saw tools, specifically to a cutting precision adjustment structure for a double-bevel circular saw, belonging to the field of power tools. Background Technology

[0002] A circular saw is a power tool widely used in woodworking, metal processing, and building material cutting. It cuts materials using a high-speed rotating circular saw blade, and is characterized by high efficiency and precision. It is an indispensable tool in the modern construction and manufacturing industries.

[0003] Currently available circular saws can generally only make large-scale inclined cuts in one direction, while it is difficult to make inclined cuts or large-scale inclined cuts in the other direction, which limits the cutting operation of circular saws.

[0004] Currently, most circular saws on the market adjust the cutting angle by aligning an angle pointer with the scale lines. However, there are some problems with this method: 1. It is difficult to achieve rapid positioning. For example, when adjusting the angle pointer to make the saw blade vertical or at other angles, the angle pointer must first be aligned with the scale line, and then the angle pointer is locked at the desired scale line position. This process is complicated and cumbersome. 2. There may be deviations in cutting accuracy. For example, when adjusting the angle pointer to make the saw blade perpendicular or at other angles, the saw blade may not be accurately positioned due to slight angular deviations during the process of aligning the angle pointer with the scale line, which will lead to a decrease in cutting accuracy.

Connections can be direct or indirect through an intermediate medium, and can be internal communication between two components or an interaction between two components.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments: like Figure 1-5 As shown, a cutting accuracy adjustment structure for a double-bevel circular saw is disclosed. The circular saw includes a base 1, a circular saw body 2 disposed above the base 1, and at least one inclined guide 3 disposed between the circular saw body 2 and the base 1. The inclined guide 3 is disposed on the upper surface of the base 1, and the circular saw body 2 is connected to the inclined guide 3. The circular saw body 2 can rotate left and right relative to the base 1 based on the inclined guide 3.

[0030] The tilting guide part 3 of this application includes a tilting movable part 4, which can rotate left and right relative to the base 1. The tilting movable part 4 is connected to the circular saw body 2, and the circular saw body 2 can rotate left and right through the tilting movable part 4.

[0031] The preferred number of inclined guide parts 3 in this application is two, divided into a front inclined guide part and a rear inclined guide part. The front inclined guide part is located on the upper surface of the front end of the base 1, and the rear inclined guide part is located on the upper surface of the rear end of the base 1. The circular saw body 2 is located between the front inclined guide part and the rear inclined guide part. More specifically, the circular saw body 2 is located between the inclined movable part 4 on the front inclined guide part and the inclined movable part 4 on the rear inclined guide part. The front inclined guide part and the rear inclined guide part together support the circular saw body 2, thereby enabling the circular saw body 2 to rotate left and right relative to the base 1.

[0032] The circular saw of this application also includes a saw blade. A saw blade groove is opened on the base 1, and the saw blade passes through the saw blade groove to cut the material to be cut. The circular saw body 2 of this application is the main part of the circular saw, which includes a motor, transmission structure, etc. The motor is the drive source, and the motor drives the saw blade to rotate at high speed through the transmission structure. Since the existing technology of the circular saw body 2 is relatively mature, the details of the circular saw body 2 will not be described in detail here.

[0033] The tilting guide portion 3 of this application also includes a tilting fixing portion 11 and a tilting intermediate portion 12. The tilting fixing portion 11 is fixedly disposed on the upper surface of the base 1, and the tilting intermediate portion 12 is located between the tilting fixing portion 11 and the tilting movable portion 4. At least one first arc-shaped guide groove 13 is formed on the side of the tilting fixing portion 11 facing the tilting intermediate portion 12, and at least one first arc-shaped guide rail 14 is provided on the side of the tilting intermediate portion 12 facing the tilting fixing portion 11. The number of first arc-shaped guide grooves 13 and first arc-shaped guide rails 14 is the same, and both are designed along the left-right direction. The first arc-shaped guide grooves 13 and first arc-shaped guide rails 14 cooperate to allow the tilting intermediate portion 12 to rotate left and right relative to the tilting fixing portion 11. At least one second arc-shaped guide rail 15 is provided on the side of the inclined middle part 12 facing the inclined movable part 4. At least one second arc-shaped guide groove 16 is formed on the side of the inclined movable part 4 facing the inclined middle part 12. The number of second arc-shaped guide grooves 16 and second arc-shaped guide rails 15 is the same, and both are designed along the left-right direction. The second arc-shaped guide grooves 16 and second arc-shaped guide rails 15 cooperate to allow the inclined movable part 4 to rotate left and right relative to the inclined middle part 12. Based on the fact that the inclined middle part 12 can rotate left and right relative to the inclined fixed part 11 and the inclined movable part 4 can rotate left and right relative to the inclined middle part 12, the circular saw body 2 can be rotated left and right, thereby realizing bidirectional oblique cutting of the circular saw.

[0034] The first arc-shaped guide groove 13 and the first arc-shaped guide rail 14 of this application are both designed with the first axis as the center. Therefore, the inclined middle part 12 of this application can rotate left and right relative to the inclined fixed part 11 with the first axis as the center. The second arc-shaped guide rail 15 and the second arc-shaped guide groove 16 of this application are both designed with the second axis as the center. Therefore, the inclined movable part 4 of this application can rotate left and right relative to the inclined middle part 12 with the second axis as the center. The first axis and the second axis of this application are both arranged in the front-back direction. The first axis and the second axis are arranged parallel to the base 1 at intervals. The first axis and the second axis are arranged parallel to each other at intervals and do not overlap.

[0035] The locking bracket 5 of this application has a circular cross-section. A rotating ring 7 is movably fitted around the outside of the locking bracket 5, allowing the rotating ring 7 to rotate around the locking bracket 5, meaning the rotating ring 7 can rotate around the locking bracket 5 as the center. A limiting bracket 6 is formed on the outer end wall of the rotating ring 7 and protrudes outward. The limiting bracket 6 can achieve a rotatable connection with the locking bracket 5 through the rotating ring 7. The limiting bracket 6 can rotate around the locking bracket 5, meaning the limiting bracket 6 can rotate around the locking bracket 5 as the center. During the rotation of the limiting bracket 6, its end passes through the rotational circumferential path of the inclined movable part 4, meaning the rotational circumferential path of the end of the limiting bracket 6 coincides with the rotational circumferential path of the inclined movable part 4. This allows the inclined movable part 4 to abut against the limiting bracket 6 during rotation. The end of the limiting bracket 6 in this application refers to the end of the limiting bracket 6 that protrudes outward from the outer end wall of the rotating ring 7. The rotational circumferential path of the inclined movable part 4 in this application refers to the arc-shaped path of the inclined movable part 4 rotating relative to the base 1.

[0036] The locking bracket 5 in this application uses a locking screw, which can be a three-piece set screw. A three-piece set screw consists of a screw, a flat washer, and a spring washer; this is a common combination and is often referred to as a spring-flat washer set screw. The upper surface of the base 1 has a locking screw hole. The locking screw is screwed into the locking screw hole, and the rotating ring 7 is fitted around the locking screw and can rotate around it. As the locking screw is continuously screwed into the locking screw hole, it presses the rotating ring 7, fixing its position and thus locking the position of the limiting bracket 6. As the locking screw is continuously screwed out of the locking screw hole, it loosens the rotating ring 7, causing it to loosen and allowing the limiting bracket 6 to move freely. At this point, the position of the limiting bracket 6 can be freely adjusted. This application uses locking screws to lock or loosen the position of the rotating ring 7, which not only facilitates the adjustment of the limit bracket 6 to achieve circular saw limit cutting or bidirectional oblique cutting, but also effectively avoids the decrease in circular saw limit cutting accuracy caused by the loosening of the position of the limit bracket 6 during circular saw limit cutting, and also effectively avoids the interference of the circular saw bidirectional oblique cutting caused by the swinging of the position of the limit bracket 6 during circular saw bidirectional oblique cutting.

[0037] During the rotation of the limiting bracket 6 in this application, its end passes through the rotational circumferential path of the inclined movable part 4. That is, the rotational circumferential path of the end of the limiting bracket 6 coincides with the rotational circumferential path of the inclined movable part 4. This design allows one end of the inclined movable part 4 to abut against the end of the limiting bracket 6 during the rotation of the inclined movable part 4, thereby achieving rotational limiting of the inclined movable part 4. When the inclined movable part 4 is rotationally limited, the circular saw body 2 connected to it is also limited, thereby achieving circular saw limited cutting. Based on the rotation of the inclined movable part 4 abutting against the limiting bracket 6, this application can not only achieve rapid limiting of the circular saw and rapid positioning and cutting of the circular saw, but also effectively avoid the problems of cumbersome process and angle deviation caused by aligning the scale lines with the angle pointer, thus effectively ensuring the cutting accuracy of the circular saw.

[0038] In this application, the locking bracket 5 is preferably positioned to correspond to the tilting movable part 4 in the left-right direction, which facilitates the design of the limiting bracket 6. To facilitate the rotation of the limiting bracket 6, the outer end wall of the rotating ring 7 can also protrude outward to form a handle. The handle facilitates the operation of the limiting bracket 6 by rotating the ring 7.

[0039] The limiting bracket 6 of this application has an abutment surface 8 at its end, which abuts against the tilting movable part 4. To enable the tilting movable part 4 to be rotated and limited, and also to calibrate the circular saw cutting angle deviation or adjust other cutting angles, a limiting screw hole 9 is provided on the tilting movable part 4 at the abutment point with the limiting bracket 6. A limiting screw 10 is provided in the limiting screw hole 9, extending downwards through the limiting screw hole 9. Rotation of the tilting movable part 4 can drive the limiting screw 10 to abut against the abutment surface 8 of the limiting bracket 6. When the tilting movable part 4 rotates and drives the limiting screw 10 to abut against the abutment surface 8 of the limiting bracket 6, the position of the tilting movable part 4 can be adjusted by the limiting screw 10, thereby calibrating the circular saw cutting angle deviation and adjusting the circular saw cutting accuracy, effectively improving the circular saw cutting precision. When the tilting movable part 4 rotates and drives the limiting screw 10 to abut against the abutting surface 8 of the limiting bracket 6, the position of the tilting movable part 4 can also be adjusted by the limiting screw 10 to achieve limiting cuts at other angles of the circular saw.

[0040] To facilitate adjustment of the limiting screw 10, the limiting screw hole 9 in this application is designed with open ends along its length. To ensure that the limiting screw 10 extending from the limiting screw hole 9 better acts on the abutment surface 8 of the limiting bracket 6, the limiting screw hole 9 can be set perpendicular to the abutment surface 8 of the limiting bracket 6. The limiting screw 10 in this application can be, but is not limited to, a hexagonal headstock set screw.

[0041] The circular saw of this application also includes an auxiliary handle 17, which is vertically fixed on the upper surface of the base 1 and provides convenience for the operation of the circular saw.

[0042] In this application, the rotating limiting bracket 6 is positioned so that its end is on the rotational circumferential path of the inclined movable part 4. The rotation of the inclined movable part 4 is restricted by the limiting bracket 6, thus limiting the circular saw and achieving positioning cut. This effectively avoids the cumbersome process and angle deviation issues associated with aligning the scale lines with an angle pointer, ensuring the cutting accuracy of the circular saw. When the end of the limiting bracket 6 is misaligned from the rotational circumferential path of the inclined movable part 4, the rotation of the inclined movable part 4 is not restricted by the limiting bracket 6, allowing the circular saw to perform bidirectional oblique cuts. The positioning cut of the circular saw in this application refers to the limiting cut achieved after the circular saw is limited.

[0043] The position of the end of the limiting bracket 6 on the rotational circumferential path of the inclined movable part 4 needs to be designed according to actual needs. The angle at which the circular saw limits the cutting will be different depending on the position of the end of the limiting bracket 6 on the rotational circumferential path of the inclined movable part 4.

[0044] Below, we will use a circular saw for vertical limiting cutting as an example to illustrate: By designing the limiting bracket 6, when the circular saw blade is vertical, the tilting movable part 4 can just drive its upper limit screw 10 to abut against the abutment surface 8 of the limiting bracket 6. By turning the locking screw, the position of the rotating ring 7 can be locked or loosened, thereby fixing or freeing the position of the limiting bracket 6. When the limiting bracket 6 is rotated so that its end is misaligned with the rotation path of the tilting movable part 4, the rotation of the tilting movable part 4 is not restricted by the obstruction of the limiting bracket 6, and the circular saw can achieve bidirectional oblique cutting. When the limiting bracket 6 is rotated so that its end is on the rotation path of the tilting movable part 4, the rotation of the tilting movable part 4 is restricted by the obstruction of the limiting bracket 6, and the rotation of the tilting movable part 4 will drive its upper limit screw 10 to abut against the abutment surface 8 of the limiting bracket 6. At this time, the circular saw blade is in a vertical state, and the circular saw can achieve vertical limiting cutting.

[0045] When the tilting movable part 4 drives its upper limit screw 10 to just abut against the abutting surface 8 of the limit bracket 6, the saw blade should be in a vertical state. However, if the saw blade is not completely vertical at this time, but has a slight angular deviation, it can be adjusted by the limit screw 10 to calibrate the saw blade deviation angle, so that the saw blade is in a vertical state again, and the circular saw can achieve vertical limit cutting.

[0046] When the tilting movable part 4 drives its upper limit screw 10 to just abut against the abutting surface 8 of the limit bracket 6, the saw blade should be in a vertical state. If you want to achieve limit cutting at other angles of the saw blade at this time, you can also adjust the limit screw 10 to make the saw blade tilt, thereby achieving limit cutting at other angles other than vertical of the circular saw.

[0047] In addition to adjusting the circular saw cutting angle through the limiting screw 10, this application can also adjust the circular saw cutting angle by designing the number and position of the limiting brackets 6. For example, multiple limiting brackets 6 are formed by protruding outward on the outer end wall of the rotating ring 7. Each limiting bracket 6 rotates around the locking bracket 5. During the rotation, the end of each limiting bracket 6 passes through the rotational circumference path of the inclined movable part 4. However, the position of the end of each limiting bracket 6 passing through the rotational circumference path of the inclined movable part 4 is different. In this way, by adjusting the different limiting brackets 6 to abut against the inclined movable part 4, the inclined movable part 4 can be limited at different positions, thereby realizing the adjustment of the circular saw cutting angle.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
