[0010] In a possible embodiment, the relative position information of the host relative to the base plate is divided into multiple segments of information.

The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0048] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0049] See also Figure 1 and Figure 2 The present embodiment provides a cutting machine 100, which is equipped with a saw blade 12. The cutting machine 100 includes a base plate 10, a main unit 11 movably mounted on the base plate 10, and an indication component 14 mounted on the main unit 11. The indication component 14 includes an indicator light group 141 arranged on the side of the saw blade 12 and a sensing component 142 electrically connected to the indicator light group 141. The indicator light group 141 emits a light beam toward the base plate 10 to form an indication light spot 15 on the base plate 10. The sensing component 142 senses the relative position information of the main unit 11 relative to the base plate 10. The indicator light group 141 adjusts the position of the indication light spot 15 according to the relative position information so that the indication light spot 15 is irradiated on the front end position 13 of the corresponding saw blade 12.

[0050] In this embodiment, the front end position 13 of the saw blade 12 refers to the position of the intersection of the saw blade 12 and the projection surface 102 of the bottom plate 10 along the width direction Y.

[0051] In this embodiment, the main machine 11 is hinged to the bottom plate 10 , so that the main machine 11 can rotate relative to the bottom plate 10 to drive the saw blade 12 to move up and down to control the cutting depth.

[0052] The host 11 has a driving component such as a motor, which is connected to the saw blade 12 to drive the saw blade 12 to rotate, thereby achieving cutting of the target object.

[0053] Continue to see Figure 1 and Figure 2In this embodiment, the indicating light spot 15 is a linear light spot 151 perpendicular to the cutting direction X of the saw blade 12 .

[0054] In this embodiment, the linear light spot 151 is located on the projection surface 102 of the bottom plate 10, and the linear light spot 151 is projected on the projection surface 102. The straight line where the linear light spot 151 is located passes through the front end position 13 of the saw blade 12. Among them, the projection surface 102 is located on the upper surface of the bottom plate 10 on the side facing the main machine 11 along the vertical direction Z, which is convenient for observing the front end position 13 of the saw blade 12 when operating the cutting machine 100.

[0055] In other embodiments, the indicating light spot may be a point light spot indicating the position corresponding to the front end of the saw blade along the width direction, or the indicating light spot may be a planar light spot, and the straight line where the front edge of the planar light spot is located passes through the front end position.

[0056] In this embodiment, the relative position information may be a moving distance of the host 11 relative to the base plate 10 or a rotation angle of the host 11 relative to the base plate 10 .

[0057] See also Figure 3 In this embodiment, the indicator light group 141 includes a plurality of indicator lights, which are arranged at intervals and have different light emission directions. When the relative position information of the main unit 11 relative to the base plate 10 changes, different indicator lights are switched to emit light so that the indicator light spot 15 remains irradiated on the front end position 13 of the corresponding saw blade 12.

[0058] Specifically, in this embodiment, the sensing component 142 divides the relative position information of the main machine 11 relative to the bottom plate 10 (such as the opening angle of the main machine 11 or the cutting depth of the saw blade 12, etc.) into multiple segments, and multiple indicator lights are arranged at intervals in the indicator light group 141. The light emitting direction of each indicator light and the angle between the cutting direction X of the saw blade 12 are different. When the relative position information obtained by the sensing component 142 falls within the range of the corresponding information segment, the corresponding indicator light turns on to emit a light beam to form an indicating light spot 15, and the other indicator lights are turned off, so that the indicating light spot 15 indicates the front end position 13 of the saw blade 12. According to different requirements for cutting accuracy, different numbers of indicator lights can be set to indicate the front end position 13 of the saw blade 12.

[0059] In this embodiment, the sensing component 142 senses the relative position information of the host 11 relative to the bottom plate 10 to turn on the corresponding indicator light to generate the indicator light spot 15. When the relative position information changes between the maximum and the minimum, the indicator light group 141 can move within the indicator light spot adjustment area 103. There are several indicator points on the indicator light spot adjustment area 103. When the relative position information obtained by the sensing component 142 falls within the range of the corresponding information segment, the corresponding indicator light turns on and emits a light beam to illuminate the corresponding indicator point. Figure 3In this embodiment, a depth gauge 16 is convexly provided on the bottom plate 10, and the depth gauge 16 is provided with an arc-shaped groove 161. The main body 11 has a first end 111 and a second end 112 which are arranged opposite to each other, the first end 111 is hinged to the bottom plate 10, and the second end 112 can be slidably matched between the arc-shaped groove 161. The arc-shaped groove 161 limits the arc-shaped movement range of the second end 112, thereby limiting the cutting depth of the saw blade 12.

[0060] In this embodiment, the depth gauge 16 is provided with scales for displaying the cutting depth of the saw blade 12 for the convenience of the user to read.

[0061] In this embodiment, preferably, the indicator light group 141 is disposed on a side of the main machine 11 close to the front end position 13 of the saw blade 12 .

[0062] See also Figure 3 In this embodiment, the sensing component 142 includes a sensing element 1421 and a sensed portion 1422. The sensing element 1421 is disposed on the host 11, and the sensed portion 1422 is disposed on the bottom plate 10. In other embodiments, the sensing element is disposed on the host, and the sensed portion is disposed on the bottom plate.

[0063] In this embodiment, the sensing element 1421 is a Hall sensor, and the sensed part 1422 is a magnetic part. The sensing element 1421 obtains relative position information by sensing the distance between the sensing element 1421 and the sensed part 1422 through the Hall effect. In other embodiments, the sensing element and the sensed part can obtain relative position information by other non-contact sensing methods, such as infrared sensing devices.

[0064] See also Figure 4 In this embodiment, the bottom plate 10 is provided with a through slot 101 through which the saw blade 12 passes. The indicator light group 141 is located on one axial side of the saw blade 12 and is used to form an indicator light spot 15 on the surface of the bottom plate 10 on the side of the through slot 101.

[0065] In this embodiment, the indicating light spot 15 is a linear light spot 151 , and the linear light spot 151 is close to one end of the saw blade 12 and extends to the edge of the through slot 101 .

[0066] See also Figure 5In this embodiment, the cutting machine 100 operates to change the cutting depth position of the saw blade 12 to achieve cutting, wherein the cutting depth position is the front end position 13 of the saw blade 12 when the saw blade 12 is at a cutting depth (cutting depth). There are many cutting depth positions between the maximum cutting depth position and the minimum cutting depth position, and each cutting depth position corresponds to an indicator light. The user changes the cutting depth of the saw blade 12 by operating the host 11. After the sensing component 142 senses the cutting depth of the saw blade 12, it determines whether the saw blade 12 has reached the specified cutting depth position, and whenever the saw blade 12 reaches a cutting depth position, the corresponding indicator light turns on and the other indicator lights turn off to form an indicator light spot 15, indicating the front end position 13 of the saw blade 12. After observing the indicator light spot 15, the user can adjust the cutting depth according to the front end position 13 of the saw blade 12 to achieve the effect of controlling the saw blade 12 to cut along the cutting direction X.

[0067] In summary, the cutting machine 100 provided in this embodiment is provided with an indicator light group 141 on the main machine 11 and controlled by the sensing component 142, so that the indicator light group 141 illuminates the bottom plate 10 to generate an indication light spot 15 corresponding to the front end position 13 of the saw blade 12. When the cutting machine 100 provided in this embodiment is used, there is no need to directly observe the position of the saw blade 12 during cutting, which facilitates observation and improves safety.

[0068] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
