[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention; that is, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Specific embodiments of the positioning device for cutting sheet metal provided by this utility model: Please see Figure 1-5 A positioning device for cutting sheet metal includes a connecting plate 1. Both ends of the connecting plate 1 are connected to parallel rails 2 on the same side. The rails 2 are perpendicularly connected to the connecting plate 1. There are two rails 2, and the two rails 2 and the connecting plate 1 form a U-shaped structure.

[0020] The lower surface of track 2 is flat, and the lower surfaces of both tracks 2 are flush. The lower surface of track 2 can be placed against the upper surface of the wooden board for smooth movement.

[0021] A backing plate 3 is connected to the lower side of the connecting plate 1; the backing plate 3 can move along the edge of the wooden board.

[0022] A U-shaped handle 7 is connected to the middle of the connecting plate 1. The handle 7 can be used to easily drive the positioning device to move on the surface of the wooden board; at the same time, the positioning device is easy to carry.

[0023] A mounting plate 4 for mounting a cutting machine 12 is provided between the two tracks 2. In some embodiments, the cutting machine 12 has a handle, and a slide block 5 that slides along the track 2 is provided on the outside of the track 2. The two sides of the track 2 are respectively connected to the slide blocks 5 on the outside of the two tracks 2. The distance between the mounting plate 4 and the backing plate 3 is changed by the slide blocks 5. This changes the distance between the cutting blade of the cutting machine 12 and the backing plate 3, thereby adjusting the width of the cut wood board.

[0024] The cross-section of track 2 is I-shaped, and the slide 5 surrounds the upper outer side of track 2 and slides stably along track 2.

[0025] Each slide 5 is threaded with two fastening screws 11. The fastening screws 11 pass through the upper side wall and inner end of the slide 5, and abut against the track 2. Tightening the fastening screws 11 ensures the stability of the slide 5 on the track 2, preventing the slide 5 from moving and thus ensuring the stability of the cutting disc position during cutting. Loosening the fastening screws 11 allows for the free adjustment of the positions of the slide 5, the mounting plate 4, and the cutting machine 12. In some embodiments, the head of the fastening screw 11 is provided with a stalk.

[0026] An anti-slip plate 8 is bolted to the end of track 2. The anti-slip plate 8 is connected to track 2 to ensure the stability of the spacing at the end of track 2 and to prevent the slide 5 from slipping off track 2. A bolt is threaded through the anti-slip plate 8, and the end of track 2 has an internal threaded hole that mates with the bolt. By removing the anti-slip plate 8, the slide 5 and the mounting plate 4 can be removed from the end of track 2.

[0027] The track 2 has a scale 9 on its upper side; the slide 5 has a notch on the upper wall near the connecting plate 1, through which the scale 9 can be observed vertically; the notch has a pointer 10 that indicates the scale 9 on its inner side; the position of the pointer 10 corresponds to the cutting blade of the cutting machine 12, and together with the scale 9, it can indicate the distance between the cutting position of the cutting blade and the backing plate 3.

[0028] The first end of the mounting plate 4 is close to the connecting plate 1, and the second end of the mounting plate 4 is close to the anti-detachment plate 8. The first end of the mounting plate 4 is rotatably connected to the slide 5; the second end of the mounting plate 4 is connected to the slide 5 through the locking assembly 6; the locking assembly 6 positions the second end of the mounting plate 4 in different positions.

[0029] like Figure 5 As shown, after adjusting the angles of the mounting plate 4 and the cutting machine 12, the cutting blade tilts, allowing for tilted cutting of the wooden board. The tilted-cut board can then be rotated for splicing. The rotation point of the mounting plate 4 is below pointer 10 but corresponds laterally to pointer 10; this lateral position corresponds to the transverse direction of the track 2.

[0030] The first end of the mounting plate 4 is rotatably connected to the two slides 5 on both sides of the first end; the second end of the mounting plate 4 is connected to the two slides 5 through two sets of locking components 6.

[0031] In this embodiment, the locking assembly 6 includes a stud 62, an arc-shaped frame 61, and a nut 63. The stud 62 is connected to the mounting plate 4, and the arc-shaped frame 61 is connected to the slide block 5. The stud 62 passes through the arc-shaped frame 61 and its end is connected to the nut 63; preferably, the nut 63 is a wing nut. A pad 64 is provided at the second end of the mounting plate 4. The pad 64 fits against the side of the arc-shaped frame 61, and the stud 62 is connected to the pad 64. A reinforcing rod 65 is connected between the end of the arc-shaped frame 61 and the slide block 5. Specifically, the lower end of the arc-shaped frame 61 is connected to the slide block 5, and the upper end of the arc-shaped frame 61 is connected to the slide block 5 through the reinforcing rod 65. The reinforcing rod 65 improves the strength of the arc-shaped frame 61 and prevents the arc-shaped frame 61 from deforming.

[0032] After tightening nut 63, nut 63 and pad 64 tightly clamp the arc frame 61, fixing the position of the second end of mounting plate 4. After loosening nut 63, stud 62 at the second end of mounting plate 4 can move along the inner side of arc frame 61, changing the angle between mounting plate 4 and cutting machine 12.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
