The bearing seats are fixedly installed at the left and right ends of the base plate, and ball bearings are fixedly installed inside the bearing seats. The two ends of the rotating shaft are fixedly installed in the rotating bodies of the ball bearings. Several positioning blocks are equidistantly distributed and fixedly installed at the front end of the base plate. Several first clamping blocks are locked and fixedly connected to the positioning blocks on the rotating shaft. The rear end of the crossbar is locked and fixedly connected to the first clamping block. The second clamping block is locked and fixedly connected to the crossbar. The upper end of the longitudinal rod is locked and fixedly installed in the clamping mouth of the second clamping block by screws. The U-shaped pressure block is fixedly installed at the lower end of the longitudinal rod. The U-shaped movable block is rotatably installed at the top of the positioning block. The top of the U-shaped movable block is provided with a clamping screw communicating with its U-shaped groove. The first stop block is fixedly installed on the left side of the top surface of the base plate, and the second stop block is fixedly installed on the rear side of the top surface of the base plate.

[0013] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 3 The photovoltaic panel frame welding positioning fixture shown includes a base plate 1, bearing seats 2, a rotating shaft 21, first clamping blocks 22, a crossbar 23, a second clamping block 3, a longitudinal bar 31, a U-shaped pressure block 32, positioning blocks 4, a U-shaped movable block 42, a first stop block 5, and a second stop block 6. The bearing seats 2 are fixedly installed at both ends of the base plate 1, and ball bearings are fixedly installed inside the bearing seats 2. The cages of the ball bearings are fixedly installed inside the bearing seats 2. Both ends of the rotating shaft 21 are fixedly installed within the rotating bodies of the ball bearings. Several positioning blocks 4 are equidistantly distributed and fixedly installed at the front end of the base plate 1, and several first clamping blocks... 22 is locked and fixed to the rotating shaft 21 in a one-to-one correspondence with the positioning block 4. The rear end of the crossbar 23 is locked and fixed to the first clamping block 22. The second clamping block 3 is locked and fixed to the crossbar 23. The upper end of the vertical bar 31 is locked and fixed in the clamping mouth of the second clamping block 3 by screws. The U-shaped pressure block 32 is fixedly installed at the lower end of the vertical bar 31. The U-shaped movable block 42 is rotatably installed at the top of the positioning block 4. The top of the U-shaped movable block 42 is provided with a pressing screw 43 communicating with its U-shaped groove. The first stop block 5 is fixedly installed on the left side of the top surface of the base plate 1. The second stop block 6 is fixedly installed on the rear side of the top plate of the base plate.

[0014] The first stop block 5 and the second stop block 6 are provided with elongated holes. The first stop block 5 and the second stop block 6 are respectively screwed and locked onto the left and rear sides of the top surface of the base plate 1 through the elongated holes. The installation position of the first stop block 5 and the second stop block 6 can be easily adjusted by the cooperation of the elongated holes and screws.

[0015] The bottom surface of the base plate 1 is provided with several hexagonal positioning protrusions, and the machine base is provided with hexagonal positioning grooves that cooperate with the hexagonal positioning protrusions. The hexagonal positioning protrusions are embedded into the hexagonal positioning grooves of the machine base, and the base plate 1 is then fixed by screws. This can improve the installation and positioning accuracy of the base plate, and at the same time reduce the shear force on the screws connecting the base plate 1 and the machine base.

[0016] The clamping screw 43 is configured as a plum blossom handle screw, which makes it convenient for operators to rotate and adjust the clamping screw 43.

The operator places all the stiffening plates 71 on the bottom surface of the photovoltaic panel frame 7, flips the combination of the rotating shaft 21 with the first clamping block 22, the crossbar 23, the second clamping block 3, the vertical bar 31, and the U-shaped pressure block 32, so that the U-shaped pressure block 32 is pressed onto the stiffening plate 71. The operator flips the U-shaped movable block 42 to a vertical position, so that the front end of the crossbar 23 is placed in the U-shaped groove of the U-shaped movable block 42. The operator rotates the clamping screw 43 so that its inner end presses onto the crossbar 23 for pre-positioning. Then the operator taps the photovoltaic panel frame 7 to make it stick tightly to the first stop block 5 and the second stop block 6. Finally, the operator tightens the clamping screw 43 to press and fix the crossbar 23. At this time, the stiffening plate 71 and the bottom plate 1 can be pressed and fixed by the combination of the crossbar 23 with the second clamping block 3, the vertical bar 31, and the U-shaped pressure block 32. Then the welding operation of the stiffening plate 71 and the bottom plate 1 can be carried out.
