DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, an elevator steel plate sill splicing welding tool comprises a workbench 1, an alignment plate 2 is arranged on one side of the upper end surface of the workbench 1, a fixed rail 3 is arranged on the workbench 1, a plurality of grooves 4 are evenly opened on the upper surface of the workbench 1 and located on one side of the fixed rail 3, a slide rail 5 is arranged inside the groove 4, a movable adjustment seat 6 is arranged on the slide rail 5, a positioning bolt 7 is arranged on the adjustment seat 6, and the adjustment seat 6 can be fixed on the slide rail 5 by the positioning bolt 7, and also includes an adjustment rail 8, and the adjustment rail 8 is fixed to the adjustment seat 6 The fixed rail 3 and the adjusting rail 8 are both perpendicular to the alignment plate 2. A movable positioning seat 9 is slidably connected on the fixed rail 3 and the adjusting rail 8. A fastening bolt 10 is provided on the positioning seat 9. The positioning seat 9 can be fixed to the fixed rail 3 and the adjusting rail 8 respectively by the fastening bolts 10. Rotating clamping cylinders 11 are evenly arranged on the upper surface of the workbench 1. The fixed rail 3 is located between the rotating clamping cylinder 11 and the adjusting rail 8. A horizontal plate 12 is provided at the output end of the rotating clamping cylinder 11, and a pressure plate 13 is installed on the horizontal plate 12.

[0019] The sill 16 has two guide grooves for the movement of the guide shoe. When installing the sill 16, the guide groove opening side of the sill 16 is set upward. When welding, the guide groove opening side of the sill 16 needs to be set downward. Specifically, first measure the shortest distance between the two guide grooves in the sill 16, and then move the position of the adjustment rail 8 through the adjustment seat 6 so that the shortest distance between the adjustment rail 8 and the fixed rail 3 is roughly the same as the shortest distance between the two guide grooves, and then fix the adjustment seat 6 to the slide rail 5 through the positioning bolt 7. Then, Then, a plurality of semi-finished sills 16 can be inverted on the fixed rail 3 and the adjusting rail 8, and the fixed rail 3 and the adjusting rail 8 are both located in the groove 4 of the semi-finished sill 16, and then the semi-finished sill 16 closest to the alignment plate 2 is aligned with the alignment plate 2, and then the remaining sills 16 are moved so that two adjacent semi-finished sills 16 abut against each other, and then the positioning seats 9 on the fixed rail 3 and the adjusting rail 8 are moved. When the positioning seats 9 on the fixed rail 3 and the adjusting rail 8 abut against one end of the semi-finished sill 16, the locking bolts are tightened to realize the alignment of the two fixed sills 16. The position seat 9 is fixed to the fixed rail 3 and the adjustment rail 8 respectively. Subsequently, by controlling the output end of the rotary clamping cylinder 11 to rotate, the output end of the rotary clamping cylinder 11 drives the cross plate 12 to rotate to the top of the semi-finished sill 16, and then contracts at the output end of the rotary clamping cylinder 11, so that the height of the cross plate 12 is reduced, that is, the distance between the cross plate 12 and the semi-finished sill 16 is shortened. When the pressing plate 13 abuts against the upper surface of the semi-finished sill 16, the output end of the rotary clamping cylinder 11 stops contracting. At this time, the simultaneous positioning of multiple semi-finished sills 16 is completed, and then the adjacent two semi-finished sills 16 are welded in sequence by welding equipment. Welding is to ensure that the position between two adjacent semi-finished sills 16 will not be misaligned. Welding can be done in the form of spot welding, that is, only a few welding spots are welded. After all the semi-finished sills 16 are welded together through the welding spots, all the semi-finished sills 16 that have been welded can be removed from the workbench 1 at one time, and the unwelded positions are welded to avoid the workbench 1 causing obstruction to the welding position of the sill 16.

[0020] Furthermore, at least two pressing plates 13 are provided, the upper end of the pressing plate 13 is slidably connected to the cross plate 12, and also includes a clamping bolt 14 for fixing the pressing plate 13 on the cross plate 12. In the present specific embodiment, since the semi-finished sill 16 has two grooves 4, when the sill 16 is inverted on the workbench 1, the sill 16 has three lower planes that are in the same plane. The pressing plate 13 abuts against the planes, thereby improving the stability and accuracy of the fit between the sills 16 and the sills 16, thereby avoiding movement and dislocation during welding.

[0021] Furthermore, a scale line 15 is provided on the upper surface of the workbench 1 and on one side of the groove 4. The reference scale of the scale line 15 is provided on one side of the fixed rail 3. The reference scale of the scale line 15 is the zero scale. The side of the fixed rail 3 close to the adjustment rail 8 is aligned with the reference scale. Therefore, when moving the adjustment rail 8, by comparing the side of the adjustment rail 8 close to the fixed rail 3 with the scale line 15, the distance between the fixed rail 3 and the adjustment rail 8 can be quickly adjusted, thereby improving the adjustment efficiency of the adjustment rail 8.

[0022] Furthermore, the fixed rail 3 and the adjustable rail 8 have the same length, and one end of the fixed rail 3 and the adjustable rail 8 are both in contact with the alignment plate 2, so that the movement of the two positioning seats 9 can be controlled simultaneously to avoid a large length difference between the fixed rail 3 and the adjustable rail 8 that affects the regulation of the positioning seat 9.

[0023] Furthermore, the alignment plate 2 is detachably connected to the workbench 1, specifically, fixed by bolts. When the alignment plate 2 abuts and collides with the sill 16 for a long time, the surface will be worn, affecting the accuracy of alignment. It can be removed from the workbench 1 and the surface of the alignment plate 2 can be polished to make it easier to continue using.

[0024] The device can align and fix more than two semi-finished sills 16 at the same time, thereby improving welding efficiency. It can also fix sills 16 of different sizes, thereby increasing the application range of the device and achieving good use effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
