[0022] 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.

[0023] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a precision equipment irregular complex sheet metal shape welding positioning fixture, comprising a welding fixture working plane 1; in order to be able to clamp special-shaped parts and facilitate flipping when clamping, a first working body 7 is installed on the welding fixture working plane 1, and second working bodies 8 are installed on both sides of the first working body 7. A sheet metal positioning clamping mechanism 2 is provided on the first working body 7, a position adjustment mechanism 3 is provided on the second working body 8, and an auxiliary working mechanism 4 is provided on the first working body 7. The sheet metal is clamped by the sheet metal positioning clamping mechanism 2, and the height and flipping are adjusted by the position adjustment mechanism 3. The auxiliary working mechanism 4 collects debris and provides auxiliary support;

[0024] In order to realize the functions of clamping and convenient flipping, the sheet metal positioning clamping mechanism 2 includes a clamping frame 20, which is installed above the first working body 7, and a clamping fixed column 22 is installed on the clamping fixed column 22, and a fixed column rotor 24 is installed on the fixed column splint 25. A fixing hole 21 is opened in the clamping frame 20, and the clamping fixed column 22 is installed in the fixing hole 21. A fixed column rotation groove 23 is opened on the clamping fixed column 22, and a splint rotation groove 26 is opened on the fixed column splint 25. The column rotor 24 is installed in the fixed column rotation groove 23 and the clamping plate rotation groove 26. The position adjustment mechanism 3 includes a lifting motor 30, which is installed on the second working body 8. A lifting push rod 31 is installed on the lifting motor 30, and a rotating motor 32 is installed on the lifting push rod 31. A rotating connecting rod 33 is installed on the rotating motor 32. A slot is opened on the second working body 8, and the lifting motor 30 is installed in the slot. The output end of the rotating connecting rod 33 is connected to the clamping frame 20. A main body fixing seat 5 is installed on one side of the second working body 8. The main body is fixed A fixing bolt 6 is installed in the seat 5, and the workpiece is placed in the clamping frame 20. Threads are opened in the fixing hole 21 and the clamping fixing column 22. The clamping fixing column 22 is rotated, and the clamping fixing column 22 drives the fixing column clamping plate 25 to approach the workpiece. When the fixing column clamping plate 25 contacts the surface of the workpiece, the fixing column clamping plate 25 drives the fixing column rotor 24 to rotate. When the fixing column rotor 24 rotates, the angle of the fixing column clamping plate 25 is adjusted until the surface of the fixing column clamping plate 25 in contact with the workpiece is completely close to the workpiece. Fix all the clamping fixing plates one by one according to the above steps. Fixed column 22, at this time the sheet metal is clamped, so that the sheet metal surface can be welded, the lifting motor 30 drives the lifting push rod 31, the lifting push rod 31 drives the rotating motor 32, and the rotating motor 32 drives the clamping frame 20 to move by rotating the connecting rod 33. When the lifting push rod 31 rises and falls, it can synchronously drive the clamping frame 20 to move, thereby adjusting the clamping height. When the welding surface needs to be flipped, the rotating motor 32 drives the rotating connecting rod 33 to rotate, and the rotating connecting rod 33 drives the clamping frame 20 to rotate, thereby turning the part over.

[0025] The working principle is as follows: the workpiece is placed in the clamping frame 20, and threads are opened in the fixing hole 21 and the clamping fixing column 22. The clamping fixing column 22 is rotated, and the clamping fixing column 22 drives the fixing column clamping plate 25 to approach the workpiece. When the fixing column clamping plate 25 contacts the surface of the workpiece, the fixing column clamping plate 25 drives the fixing column rotor 24 to rotate. When the fixing column rotor 24 rotates, the angle of the fixing column clamping plate 25 can be adjusted until the surface of the fixing column clamping plate 25 in contact with the workpiece is completely close to the workpiece. All the clamping fixing columns 22 are fixed one by one according to the above steps. At this time, the sheet metal is clamped, so that the sheet metal surface can be welded. The lifting push rod 31 is pushed by the lifting motor 30, and the lifting push rod 31 drives the rotating motor 32. The rotating motor 32 drives the clamping frame 20 to move by rotating the connecting rod 33. The lifting push rod 31 can synchronously drive the clamping frame 20 to move when it rises and falls, thereby adjusting the clamping height. When the welding surface needs to be flipped When the workpiece is turned over, the motor 32 drives the rotating connecting rod 33 to rotate, and the rotating connecting rod 33 drives the clamping frame 20 to rotate, thereby turning the part over. In order to prevent the debris generated during processing or drilling from polluting the working environment, the collecting cover 41 is inserted under the first working body 7 through the collecting cover slot 40, and the debris processed above will fall into the collecting cover 41, which can prevent the debris from falling directly on the platform and polluting the working environment. By rotating the support screw 44, when the support screw 44 is rotated in the support screw hole 43, the thread on the support screw 44 engages with the thread in the support screw hole 43, so that the support screw 44 rises or falls in the support screw hole 43, and the support screw 44 is screwed to the bottom of the clamping frame 20 so that the top surface of the support screw 44 contacts the bottom surface of the clamping frame 20, thereby playing a supporting role during work. When lifting and rotating the clamping frame 20, the support screw 44 needs to be unscrewed first.

[0026] Example 2: Figure 1-5In order to keep the desktop clean and provide auxiliary support, the auxiliary working mechanism 4 includes a collection cover 41. The welding tooling work plane 1 of the auxiliary working mechanism 4 is installed in the first working body 7. A handle 42 is installed on the collection cover 41. A support screw 44 is installed on the first working body 7. A blanking trough 40 is opened in the first working body 7. The collection cover 41 is installed in the blanking trough 40. A support screw hole 43 is opened on the first working body 7. The support screw 44 is installed in the support screw hole 43. In order to prevent debris generated during processing or drilling from contaminating the working environment, the collection cover 41 is inserted under the first working body 7 through the collection cover notch 40. The debris processed above will fall into the collection cover 41, which can prevent the debris from falling directly on the platform and polluting the working environment. By rotating the support screw 44, when the support screw 44 is rotated in the support screw hole 43, the thread on the support screw 44 engages with the thread in the support screw hole 43, so that the support screw 44 rises or falls in the support screw hole 43. The support screw 44 is rotated to the bottom of the clamping frame 20 so that the top surface of the support screw 44 contacts the bottom surface of the clamping frame 20, thereby playing a supporting role during work. When lifting and rotating the clamping frame 20, the support screw 44 needs to be unscrewed first. The remaining features are the same as those in Example 1.
