[0039] According to the actual welding requirements, the position of the welding seat 46 on the bearing seat 2 is adjusted and fixed, and the workpiece to be welded is clamped on the cover stopper 51, and the magnet 34 absorbs the workpiece. When the sensor 42 senses that the cover stopper 51 has clamped the workpiece, it transmits a signal to the controller outside the positioning device 1, and the controller controls the cylinder 31 to start working. The output end of the cylinder 31 extends, so that the guide rod 32 drives the magnetic head 33 and the magnet 34 to move forward, and the workpiece is transferred to the welding position, realizing automatic loading and precise positioning. Embodiment 2:

[0040] Based on the first embodiment, this embodiment provides a method for adjusting the position of the welding seat 46 on the bearing seat 2 and fixing it.

[0041] like Figure 3 As shown, the bearing seat 2 includes an accordion cover mounting plate 21 , a first accordion cover 22 , a second accordion cover 26 , a bottom plate 23 , a slider 24 , a guide rail 25 and a plurality of hand latch piles 27 for fixing the positioning mechanism 4 .

[0042] Specifically, the bellows cover mounting plate 21 is relatively arranged at the two ends of the guide rail 25. The first bellows cover 22 and the second bellows cover 26 for protecting the guide rail 25 are respectively installed on the opposite side of the bellows cover mounting plate 21, and the first bellows cover 22 and the second bellows cover 26 are both located above the guide rail 25.

The hand latch pile 27 is arranged on one side of the bottom plate 23.

[0043] Furthermore, in this embodiment, five hand latch piles 27 are provided.

[0044] like Figure 6 and 7 As shown, the positioning mechanism 4 also includes a tail slide plate 43 , a base adjustment plate 44 and an adjustment block 45 .

[0045] Specifically, the tail slide plate 43 is connected to the top of the slider 24. A pin hole is provided on the side of the tail slide plate 43 close to the hand latch pile 27, and a hand latch cylinder sleeve 52 is provided on the pin hole. The tail slide plate 43 is fixed above the bottom plate 23 by the hand latch locking pin 53 passing through the hand latch cylinder sleeve 52 and extending into the hand latch pile 27. A screw hole is provided at the corner of the base adjustment plate 44, and a flat washer 47 is provided on the screw hole. The base adjustment plate 44 is fixed to the top of the tail slide plate 43 by bolts passing through the flat washer 47 and screwing into the screw hole. The welding seat 46 is installed on the top of the base adjustment plate 44. The adjustment block 45 is provided on the peripheral side of the base adjustment plate 44, and is used to adjust the position of the base adjustment plate 44. An adjustment gasket 48 is provided between the adjustment block 45 and the base adjustment plate 44, and is used to achieve fine adjustment of the base adjustment plate 44.

The adjustment blocks 45 are provided with screw holes, and when the position of the base adjustment plate 44 is adjusted, the position of the adjustment blocks 45 is fixed by screwing bolts into the screw holes.

[0047] The position adjustment method of the welding seat 46 is as follows:

[0048] According to the actual welding requirements and the length of the workpiece, the tail slide 43 is driven by the slider 24 to slide on the guide rail 25, and the welding seat 46 carried by the tail slide 43 slides together to achieve coarse adjustment. After sliding to the appropriate position, the tail slide 43 is fixed above the bottom plate 23 by inserting the hand-inserted locking pin 53 into the hand-inserted pin pile 27. After the coarse adjustment is completed, the position of the base adjustment plate 44 is adjusted by moving the adjustment block 45 to achieve fine adjustment until the guide rod 32 can pass through the circular hole on the welding seat to the through hole on the cover limit block 51. After the fine adjustment is completed, the position of the adjustment block 45 and the base adjustment plate 44 is fixed by bolts, and the workpiece can be clamped on the cover limit block 51 to start positioning and loading.

[0049] Furthermore, when the tail slide plate 43 is driven by the slider 24 to slide on the guide rail 25, if the slider 24 touches the first accordion cover 22 and the second accordion cover 26, the first accordion cover 22 and the second accordion cover 26 will extend or shorten along the moving direction of the slider 24 without affecting the sliding of the slider 24.
