[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a positioning plate for assembling a range hood wing bracket, comprising a processing table 1, a positioning plate 2 is provided on the top of the processing table 1, a turntable 3 is provided between the positioning plate 2 and the processing table 1, a motor 4 is fixedly connected to the bottom of the processing table 1, and the output shaft of the motor 4 extends to the top of the processing table 1 and is fixedly connected to the turntable 3, a support plate 9 is provided on the top of the turntable 3, a connecting shaft 8 is provided on the circumference of the positioning plate 2, and the connecting shaft 8 is connected to the support plate 9, a plurality of clamping blocks 5 are provided on the top of the positioning plate 2, a slide groove is opened on the top of the positioning plate 2, the clamping block 5 is slidably connected to the positioning plate 2 through the slide groove, and a fixing mechanism is provided between the clamping block 5 and the positioning plate 2.

[0023] According to the overall structure of the device, the bracket is placed on the positioning plate 2, the clamping block 5 is moved so that the clamping block 5 is tightly attached to the side of the bracket, and the clamping block 5 is fixed by the fixing mechanism, so that the bracket is clamped and fixed by the fixed clamping block 5 to complete the positioning of the bracket. The positioning plate 2 can be deflected by the connecting shaft 8 and the support plate 9, and the turntable 3 is driven by the motor 4 to rotate to cooperate with the positioning plate 2 to adjust the bracket angle, which is convenient for bracket installation.

[0024] like Figure 1 、 2 As shown, there are four support plates 9 and connecting shafts 8, and the four support plates 9 and connecting shafts 8 are distributed in a cross shape. The support plate 9 is set in a door shape, and the connecting shaft 8 is inserted into the inner side of the support plate 9. The connecting shaft 8 is movably connected to the positioning plate 2. A slot is provided at one end of the connecting shaft 8 inserted into the inner side of the support plate 9, and a baffle 10 is movably connected in the slot. A number of slots matching the baffle 10 are provided on the support plate 9.

[0025] The positioning disk 2 is supported by the connecting shaft 8 and the support plate 9. Any two connecting shafts 8 are engaged with the support plate 9, and the other two connecting shafts 8 are loosened from the support plate 9. At this time, the positioning disk 2 can rotate with the fixed connecting shaft 8. Then, the states of the four connecting shafts 8 are switched to the opposite state, so that the positioning disk 2 rotates with another pair of connecting shafts 8, thereby deflecting the positioning disk 2 up and down, and the current position of the connecting shaft 8 can be engaged and fixed by the blocking rod 10 and the card slot to fix the deflected positioning disk 2, and then the motor 4 drives the rotation of the turntable 3, so that the positioning disk 2 can be adjusted at multiple angles. The structure is simple and the operation is easy.

[0026] like Figure 1 As shown, the slide groove is composed of an annular groove and several linear grooves. The annular groove is located at the outer edge of the positioning plate 2, and the linear groove is located inside the annular groove. The several linear grooves are evenly divided into longitudinal and transverse directions and are staggered.

[0027] The clamping block 5 can be moved on the positioning plate 2 through the sliding groove, so that the position of the clamping block 5 and the distance between the two clamping blocks 5 can be adjusted according to the shape and structure of the bracket, which is convenient for clamping and fixing different types of brackets.

[0028] like Figure 3 As shown, the fixing mechanism includes a screw 6, a threaded hole is provided on the clamping block 5, the screw 6 is threadedly connected in the threaded hole, a knob is fixedly connected to the top of the screw 6, and a nut 7 is threadedly connected to the screw 6, there are two nuts 7, the bottom of the clamping block 5 is provided with a groove, the two nuts 7 are distributed in the groove and the slide groove, the screw 6 passes through the two nuts 7 in turn, the thread on the screw 6 is divided into two parts, the upper and lower parts, and the threads of the two parts are rotated in opposite directions.

[0029] By turning the screw rod 6 with the knob, the two nuts 7 move in opposite directions, thereby increasing the distance between the two nuts 7 and loosening the two nuts 7 on the inside and outside of the slide. At this time, the clamping block 5 is relaxed and can move in the slide. The screw rod 6 is rotated in the opposite direction to move the two nuts 7 relative to each other, shortening the distance between the two nuts 7. The two nuts 7 cling to the inside and outside of the slide, generating pressure to clamp them in the current position, thereby fixing the clamping block 5. Multiple clamping blocks 5 can be used to clamp and fix the bracket.

[0030] like Figure 4 As shown, the cross-sections of the annular groove and the linear groove are both convex-shaped, the two nuts 7 are both square, and the grooves are square grooves, and the bottom end of the screw 6 is fixedly connected to a limiting plate.

[0031] The square structure restricts the nut 7 in the chute and the groove and prevents it from rotating, while at the same time does not affect the linear movement of the nut 7 in the chute. Thus, when the screw 6 rotates, the chute and the groove limit the nut 7, allowing the nut 7 and the screw 6 to rotate relative to each other, so that the nut 7 can move on the screw 6. The limiting plate prevents the nut 7 in the chute from moving too much and falling off the screw 6.

[0032] Working principle: Place the bracket on the positioning plate 2, turn the screw 6 to make the two nuts 7 move away from each other, then the clamp 5 is loosened, move the clamp 5 so that the clamp 5 is close to the side of the bracket, and then turn the screw 6 in the opposite direction to make the two nuts 7 close to each other, clamp the clamp 5 in the current position to fix it, so that the bracket is clamped and fixed by the fixed clamp 5 to complete the positioning of the bracket, so that any two opposite connecting shafts 8 are fixed to the support plate 9, and the connecting shaft 8 at the other end is loosened, the positioning plate 2 can be deflected with the fixed connecting shaft 8, and then the state can be switched to make the positioning plate 2 deflect with another pair of connecting shafts 8, and at the same time, the turntable 3 is driven to rotate by the motor 4 for cooperation, so as to adjust the angle of the bracket to facilitate the installation of the bracket.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
