Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology and relates to a welding fixture. Background Technology

[0002] Currently, existing welding equipment can only weld a single spot during the welding process. If welding is to be performed on different positions of the same workpiece, multiple processes need to be carried out sequentially, requiring multiple welding machines, which is costly. Furthermore, each welding process requires re-clamping and repositioning, which takes a long time and has considerable room for improvement. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a welding fixture.

[0004] The objective of this utility model can be achieved through the following technical solution: a welding fixture, comprising:

When the first slider is in the first position, the electrode arm of one movable seat is aligned with the clamping seat. When the first slider is in the second position, the electrode arm of the other movable seat is aligned with the clamping seat.

[0009] In the above-mentioned welding fixture, a first driving element is further included. The first driving element is connected to the base, and the clamping seat is connected to the output end of the first driving element. The first driving element can drive the clamping seat to move relative to the base.

[0010] In the above-mentioned welding fixture, there are also two limiting blocks. Both limiting blocks are connected to the base. The clamping seat is located between the two limiting blocks and can contact the limiting blocks. When the clamping seat contacts one of the limiting blocks, the first slider is located in the first position. When the clamping seat contacts the other limiting block, the first slider is located in the second position.

[0011] In the above-mentioned welding fixture, a second driving element is further included. The second driving element is connected to the base, and the fixed base is connected to the output end of the second driving element. The second driving element can drive the fixed base to move relative to the base.

[0012] In the above-mentioned welding fixture, the electrode arm is provided with an electrode cap, the fixed base is also provided with a third slide rail, and the movable base is also provided with a third slider. The third slider is slidably connected to the third slide rail, and the third slide rail is parallel to the first slide rail.

[0013] In the above-mentioned welding fixture, an elastic element is also included. The two ends of the elastic element are respectively connected to the fixed base and the movable base. The elastic element drives the movable base to move relative to the fixed base toward the side where the electrode cap is located on the electrode arm.

[0014] The welding fixture described above also includes two water-cooling connectors. The electrode arm is provided with a water-cooling channel, and the two water-cooling connectors are respectively connected to the two ends of the water-cooling channel.

[0015] In the above-mentioned welding fixture, a clamping assembly is also included. The clamping assembly includes a clamping block and a clamping drive element. The clamping block is connected to the output end of the clamping drive element, and the clamping drive element is connected to the clamping seat. The clamping drive element can drive the clamping block to move closer to or away from the clamping seat.

[0016] The welding fixture described above also includes a first positioning component. The first positioning component includes a first positioning pin and a first positioning drive element. The first positioning pin is connected to the output end of the first positioning drive element, and the first positioning drive element is connected to the clamping seat. The first positioning drive element can drive the first positioning pin to move.

[0017] In the above-mentioned welding fixture, a second positioning component is also included. The second positioning component includes a second positioning pin and a second positioning drive element. The second positioning pin is connected to the output end of the second positioning drive element, and the second positioning drive element is connected to the clamping seat.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The fixed seat is slidably connected to the second slide rail via the second slider, close to the clamping seat for welding or away from the clamping seat for adjusting the position of the clamping seat. The clamping seat is slidably connected to the first slide rail via the first slider and can be moved to the first position or the second position, so that the electrode arms of different moving seats are aligned with the clamping seat, realizing the switching of welding points.

[0020] 2. The first driving element can drive the clamping seat to move relative to the base, realizing the automatic movement of the clamping seat to the first position or the second position, so there is no need to manually adjust the position of the clamping seat.

[0021] 3. When the clamping seat contacts a limiting block, the first slider is in the first position. When the clamping seat contacts another limiting block, the first slider is in the second position. This ensures that the first slider corresponds exactly to the first and second positions at the two extreme positions, thus ensuring the accuracy of the welding position.

[0022] 4. The second driving element can drive the fixed seat to move relative to the base, realizing that the fixed seat automatically makes room for the workpiece to be picked up and placed, so there is no need to manually adjust the position of the fixed seat.

[0023] 5. The elastic element drives the moving seat to move relative to the fixed seat toward the side where the electrode cap is located on the electrode arm, and drives it to slide relative to the third slide rail through the third slider, thereby compensating for the wear of the electrode cap on the electrode arm that has become shorter due to grinding.
