Description

Technical Field

[0001] The utility model relates to the technical field of circular saws, in particular to a woodworking circular saw which is easy to adjust. Background Art

[0002] The circular saw (bench wood saw) is a very common woodworking equipment. Due to its efficient cutting ability and adjustable cutting angle, it has become one of the essential equipment for woodworking.

[0003] In addition to adjusting the angle of the cutting surface, the circular saw can also adjust the cutting width. It mainly adjusts the distance between the baffle and the saw blade to achieve the effect of adjusting the cutting width. As for the position adjustment of the baffle, the common method is that the operator manually moves the baffle to the corresponding position, and then uses a butterfly nut to fix the baffle. Although this is very convenient to operate, the position of the baffle is moved manually, and the accuracy of manual movement is not high. If the screw and nut adjustment method is used, although the adjustment accuracy can be improved, when the position of the baffle needs to be adjusted back and forth over a large range, the adjustment speed of the screw and nut is very slow. Therefore, a circular saw that is easier to adjust can be designed. Utility Model Content

[0006] Furthermore, a first sliding rod is horizontally arranged at the lower side of the table top, and a limit block is provided on the first sliding rod sleeve; the first sliding rod is parallel to the screw rod, and the driving rod is rotatably connected to the limit block.

[0007] Furthermore, the limiting block is threadedly connected with a fastening bolt, and the fastening bolt abuts against the first sliding rod.

[0008] Furthermore, it also includes a connecting rod for connecting the driving block and the limiting block.

DETAILED DESCRIPTION

[0019] Example

[0020] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 4 As shown, the easily adjustable woodworking circular saw of this embodiment includes a table top 11, a long strip through hole 14 opened on the table top 11, a stop bar 21 arranged on the table top 11, a slider 22 connected to the stop bar 21 and slidably arranged in the through hole 14, a nut 23 connected to the lower side of the slider 22, a screw rod 24 threadedly connected to the nut 23, a driving block 27 rotatably connected to the end of the screw rod 24, a first umbrella-shaped tooth 25 arranged on the screw rod 24, a second umbrella-shaped tooth 26 meshing with the first umbrella-shaped tooth 25, and a driving rod 28 rotatably connected to the driving block 27; the driving rod 28 is fixedly connected to the second umbrella-shaped tooth 26. Specifically, when in use, the wooden board to be cut is placed close to the baffle 21, and then the wooden board can be pushed for cutting. When different sizes need to be cut, the driving rod 28 can be moved left and right, thereby driving the driving block 27, the screw rod 24, the nut 23, the slider 22 and the baffle 21 to move. When moved to the close position, the driving rod 28 is rotated, and then the screw rod 24 is driven to rotate through the second umbrella-shaped teeth 26 and the first umbrella-shaped teeth 25, and then the movement of the nut 23 is finely adjusted to achieve precise adjustment of the position of the baffle 21, which can improve the cutting accuracy to a certain extent and reduce the adjustment time.

[0021] In this embodiment, a first sliding rod 29 is horizontally arranged at the lower side of the table 11, and a limit block 210 is sleeved on the first sliding rod 29; the first sliding rod 29 is parallel to the screw rod 24, and the driving rod 28 is rotatably connected to the limit block 210. The limit block 210 is threadedly connected with a fastening bolt 213, and the fastening bolt 213 abuts against the first sliding rod 29. A connecting rod 211 for connecting the driving block 27 and the limit block 210 is also included. Specifically, the first sliding rod 29 and the limit block 210 can better limit the driving rod 28, so that it can slide more smoothly and stably, and the position of the limit block 210 can also be limited by tightening the fastening bolt 213, so that the limit block 210, the connecting rod 211, the driving block 27 and the screw rod 24 can no longer move. At this time, the driving rod 28 is rotated again, and the position of the nut 23, the slider 22 and the stop bar 21 can still be adjusted by driving the screw rod 24 to rotate. It should be noted that a second sliding rod 212 slidably connected to the driving block 27 may be provided, so as to better ensure that the driving block 27 performs linear motion.

[0022] Both ends of the screw rod 24 in this embodiment are rotatably connected to the driving block 27. Specifically, this can clamp the screw rod 24 more stably and prevent the screw rod from shaking during operation.

[0023] In this embodiment, a scale 12 is provided on the table 11 .

[0024] In this embodiment, a cover 13 is provided on the table 11, and the cover 13 is hinged to the table 11; the cover 13 is made of a transparent material; and a gap is provided between the cover 13 and the table 11. Specifically, the cover 13 is mainly used to prevent sawdust from flying around.

[0025] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the utility model is easy to adjust the woodworking circular saw, when in use, the wooden board to be cut is placed close to the baffle 21, and then the wooden board can be pushed for cutting. When different sizes need to be cut, the driving rod 28 can be moved left and right, thereby driving the driving block 27, the screw rod 24, the nut 23, the slider 22 and the baffle 21 to move. When moved to the close position, the driving rod 28 is rotated, and then the screw rod 24 is driven to rotate through the second umbrella-shaped teeth 26 and the first umbrella-shaped teeth 25, and then the movement of the nut 23 is finely adjusted to achieve accurate adjustment of the position of the baffle 21, which can improve the cutting accuracy to a certain extent and reduce the adjustment time.
