In addition, the same reference numerals are used for the same structures, elements or accessories appearing in two or more figures to represent similar features.

[0022] In the related art, the shells of many devices are made of sheet metal parts, and in order to meet the requirements of the structure shape, the sheet metal parts are processed into various non-standard shapes, especially various radii provided on the surface of the sheet metal part. Normal clamps cannot effectively adapt to them. In order to effectively adapt to various non-standard shapes of sheet metal parts, with reference to Figures 1 to 5 As shown in the drawings, the positioning device of the present application includes a table plate 1 arranged in an L shape. A plurality of clamping grooves 13 are arranged side by side on the side surface and the bottom surface of the table plate 1. The sheet metal part can be placed obliquely on the table plate 1. The clamping grooves 13 provided on the side surface and the bottom surface of the table plate 1 can be in contact with the upper and lower edges of the sheet metal part, thereby facilitating preliminary positioning. In the embodiment of the present application, a clamp 11 is further included. The clamp 11 is rotatably installed at the end position of the side surface and the bottom surface of the table plate 1. The clamp 11 on the side surface and the clamp 11 on the bottom surface of the table plate 1 can be rotated into a cross state, thereby compressing and fixing the outer surface of the sheet metal part. Specifically, the clamp 11 comprises a pry bar 1103, a straight frame 1104 and an end head 1105 connected in sequence, the end head 1105 is obliquely installed on the straight frame 1104, and a taper pin 1106 is further installed on the outer end of the end head 1105, and the end of the two side surfaces of the table plate 1 is further provided with a positioning lug plate 1102, and the pry bar 1103 is rotatably installed in the positioning lug plate 1102; In operation, through the design of the straight frame 1104 and the end head 1105, when the pry bar 1103 is turned over, the inclined end head 1105 will first contact the surface of the sheet metal part, and the taper pin 1106 on the end head 1105 can be in point contact with the surface of the sheet metal part, so as to adapt to various arc surfaces, and through the taper pins 1106 in the plurality of clamps 11, the sheet metal part can be fixed by multiple points, which can adapt to various radii on the surface of the sheet metal part and be effectively fixed, and has high practicability. Moreover, in order to avoid damage to the sheet metal part caused by the taper pin 1106, a rubber sleeve can be installed at the tip of the taper pin 1106, which can ensure stable support while avoiding scratching the sheet metal part.

In operation, since the bolt rod 1107 is connected with the pry bar 1103, when it is necessary to push the clamp 11 to turn over, the bolt rod 1107 can be held to adjust, and when the clamp 11 is attached to the sheet metal part and needs to be fixed, the rudder plate 1108 can be pushed to rotate on the bolt rod 1107 to approach the positioning lug plate 1102, and the rudder plate 1108 and the positioning lug plate 1102 can be fixed through extrusion fitting. Moreover, the plurality of clamps 11 are adjusted by corresponding bolt rods 1107, and the angle of each clamp 11 can be adjusted according to the convex and concave conditions of the corresponding position of the sheet metal part, so as to ensure effective fixation of the sheet metal part.

[0024] Further, in order to meet the electrical automation cooperation, referring to Figure 7 , the end of the pry bar 1103 away from the straight frame 1104 can also be provided with a first air cylinder 1113, and the first air cylinder 1113 is fixed on the support 2; a second air cylinder 1114 can also be installed between the bottom of the straight frame 1104 and the end head 1105, and the connection between the second air cylinder 1114 and the straight frame 1104 and the end head 1105 is hinged; When working, the first air cylinder 1113 can replace the bolt rod 1107 and the rudder disc 1108 to push the pry bar 1103 to flip and fix the clamp 11, and the second air cylinder 1114 can replace the inclined support rod 1112 to push the end head 1105 to flip around the straight frame 1104, so as to facilitate the stable contact of the taper pin 1106 on the surface of the sheet metal part, and the electrical auxiliary equipment can be installed on one side of the support 2, which is convenient for connection with the first air cylinder 1113 and the second air cylinder 1114.

[0026] Referring to Figures 1 to 3 , Figure 8 As shown, the two table plates 1 are further provided with a linkage 3, the linkage 3 can facilitate the synchronous movement of the two table plates 1, when the two sheet metal pieces need to be butt-welded together, the two sheet metal pieces can be fixed on the two table plates 1 respectively, and then the linkage 3 is used to pull the two sheet metal pieces close to each other for positioning, facilitating the welding; In addition, when the length of the sheet metal piece is large, the distance between the two table plates 1 can be adjusted through the linkage 3, facilitating the fixation of the sheet metal piece on the two table plates 1 at the same time; Specifically, the linkage 3 comprises a straight slot 301 installed at the bottom of the lower sliding rail 201, a positioning seat 302 slidingly assembled in the straight slot 301, and two swing rods 303 hingedly connected to the positioning seat 302, the outer ends of the two swing rods 303 are hingedly connected to the two table plates 1 respectively. The straight slot 301 is further provided with a telescopic driving piece 306, the output end of the telescopic driving piece 306 is connected to the positioning seat 302; In operation, the telescopic driving piece 306 can push the positioning seat 302 to slide in the straight slot 301, and when the positioning seat 302 slides, the two swing rods 303 are pushed to displace, when the swing rods 303 are opened, the two table plates 1 are pushed away from each other, and when the swing rods 303 are contracted, the two table plates 1 are pulled close to each other; Further, two blocking frames 305 are symmetrically installed on the lower sliding rail 201 about the straight slot 301, a compression roller 304 is rotatably installed on the end of the blocking frame 305, the compression roller 304 is in pressing cooperation with the swing rod 303 on the same side, since the blocking frame 305 and the compression roller 304 are fixedly arranged, when the positioning seat 302 slides towards the compression roller 304, the swing rod 303 will be blocked by the compression roller 304, and as the positioning seat 302 continues to move, the swing rod 303 will gradually contract due to the compression of the compression roller 304, thereby pulling the two table plates 1 close to each other, and when the positioning seat 302 reversely displaces, the swing rod 303 will be pushed to rotate like an umbrella structure, pushing the two table plates 1 away from each other, facilitating the adjustment.

[0027] On the basis of the above, in addition to non-standard sheet metal parts, general sheet metal parts can also be placed on the base plate 1 for fixation, and because multiple clamping grooves 13 are arranged side by side on the side surface and the bottom surface of the base plate 1, the sheet metal part can be fixed at multiple angles.
