Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat slide rail welding, and in particular to a welding fixture for automotive seat slide rail foot pads. Background Technology
[0002] In the production process of automotive seat rails, two foot pads need to be welded to the bottom of the rail. Different car models have different seat rail types, lengths, and mounting hole positions on the car body, resulting in different shapes of the foot pads and different spans between the two foot pads. In existing technology, to meet the requirements of different car models, different fixtures need to be customized. The drawbacks are: frequent switching of welding fixtures is required during production, affecting production line efficiency; and to ensure convenient changeover, a fixture storage area needs to be set up around the equipment, occupying production line space. Summary of the Invention
[0003] This utility model addresses the shortcomings of existing technologies by developing a welding fixture for automotive seat slide rail floor pads. The technical solution adopted by this utility model is: a welding fixture for automotive seat slide rail floor pads, characterized by comprising an upper electrode assembly 1, a lower electrode assembly 5, and a base 14; the upper electrode assembly 1 includes an upper electrode plate 2, a first upper electrode 3, and a second upper electrode 4; the first upper electrode 3 and the second upper electrode 4 are connected to the upper electrode plate 2; the lower electrode assembly 5 includes a lower electrode plate 9, a first adjustable positioning block 8, and a second adjustable positioning block 11; the first adjustable positioning block 8 and the second adjustable positioning block 11 are disposed on the lower electrode plate 9; a first electrode hole 17 is formed on the first adjustable positioning block 8; the second adjustable positioning block 11... A second electrode hole 18 is formed on the positioning block 11; a first lower electrode 6 is inserted into the first electrode hole 17; a second lower electrode 13 is inserted into the second electrode hole 18; a first set screw 19 is threadedly connected to the first lower electrode 6; a second set screw 21 is threadedly connected to the second lower electrode 13; a first positioning pin 7 is inserted into the first lower electrode 6; a second positioning pin 12 is inserted into the second lower electrode 13; a slide rail positioning seat 10 is fixedly mounted on the lower electrode plate 9; the upper end of the guide rod 16 is fixedly connected to the lower part of the lower electrode plate 9, and its lower end passes through the base 14; a spring 15 is sleeved on the guide rod 16.
[0004] The advantages of this utility model are as follows: since the lower electrode is inserted into the adjustable positioning block, and the positioning pin is inserted into the electrode, and locked with a set screw, when different seat slide rails need to be switched, only the corresponding electrode and positioning pin need to be replaced; when adjusting the span between the two foot pads, only the adjustable positioning block needs to be adjusted, which effectively avoids the time waste caused by switching the entire set of fixtures and improves production efficiency; storing different electrodes and positioning pins at the production line side can also avoid the space waste caused by storing the entire set of fixtures.
