Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, and specifically relates to a water-gas unit with a drainage function. Background Technique

[0002] In the traditional automatic spot welding process, the robot welding tongs use low voltage, large current, and short time to melt the base metal at the electrode pressing part by resistance heat to form a fusion core solder joint. Therefore, cooling water needs to be passed through the welding tongs to reduce the temperature of the welding tongs. During the welding process, the electrode cap needs to be frequently replaced as a consumable. However, when replacing the electrode cap of the robot welding tongs, although the water supply system will be immediately closed, a lot of water in the pipeline will still flow out, damaging other electrical components. Therefore, it is necessary to drain the water inside the pipeline.

[0003] For example, a Chinese patent with the patent application number 201921994873.3, a water-gas unit with an automatic drainage function, is fixed on the base through a connecting piece, and the upper end of the three-way joint is connected to a horizontal non-return valve for air and water; the Y-shaped internal thread filter for the return water path, the horizontal non-return valve for water in the return water path, and the water flow sensor are connected together from left to right through the return water path pipe. An air fluid valve and a horizontal non-return valve for air and water are added in the water-gas unit, adding a blowing circuit, with a simple structure, being economical and practical, and can avoid the residual cooling water in the pipeline from flowing out when replacing the electrode cap.

[0004] However, when using the above patent, it is necessary to fix and install the air fluid valve and the horizontal non-return valve for air and water by means of bolts, etc., which seriously affects the replacement and maintenance of the air fluid valve and the horizontal non-return valve for air and water by the operator.

Specific implementation mode

[0032] Please refer to Figures 1-4 , the present utility model provides a technical solution: a water-air unit with a drainage function, including a base 1, the two sides of the base 1 are respectively fixedly connected with a first blow pipe 3 and a second blow pipe 4 through fixing pieces 2, and the tops of the first blow pipe 3 and the second blow pipe 4 are respectively fixedly connected with a pneumatic fluid valve 5 and a horizontal swing check valve 6 for pneumatic circuit water through a rotary locking mechanism.

[0033] By adopting the above technical solution, a one-way blowing system is formed between the pneumatic circuit system and the water inlet circuit through the pneumatic fluid valve 5 and the horizontal swing check valve 6 for pneumatic circuit water. The gas is blown into the water inlet circuit unidirectionally through the horizontal swing check valve 6 for pneumatic circuit water, and the residual cooling water in the pipeline is blown into the return water circuit through air pressure, so that the remaining water in the robot welding tongs can be quickly drained.

[0034] In the embodiment of the present application, as Figures 2-3 shown, the rotary locking mechanism includes a first connection plate 7 installed at the tops of the first blow pipe 3 and the second blow pipe 4 and a second connection plate 8 installed at the bottoms of the pneumatic fluid valve 5 and the horizontal swing check valve 6 for pneumatic circuit water.

A plurality of positioning mechanisms are arranged between the first connection plate 7 and the second connection plate 8.

[0035] By adopting the above technical solution, the device can quickly fix the first connection plate 7 and the second connection plate 8 through the rotary locking mechanism, which greatly facilitates the installation and disassembly of the pneumatic fluid valve 5 and the horizontal swing check valve 6 for pneumatic circuit water by the operator, and further greatly improves the replacement and maintenance efficiency of the pneumatic fluid valve 5 and the horizontal swing check valve 6 for pneumatic circuit water by the maintenance personnel.

[0036] In the embodiment of the present application, as Figures 3-4As shown in the figure, the positioning mechanism includes a fixed rod 10 installed inside the second connection plate 8 and a plurality of positioning holes 20 opened at the top of the first connection plate 7. A pull rod 11 is movably arranged inside the cavity of the fixed rod 10. One side of the pull rod 11 extends into the positioning hole 20 and is fixedly connected with a positioning rod 12. The other side of the pull rod 11 extends outside the fixed rod 10 and is fixedly connected with a pull plate 13. A spring 14 is arranged on the outer surface of the pull rod 11 located inside the fixed rod 10.

[0037] By adopting the above technical solution, the device can position and fix the first connection plate 7 and the second connection plate 8 through the positioning mechanism, thereby effectively avoiding relative sliding between the first connection plate 7 and the second connection plate 8, and greatly improving the installation stability of the device.

[0038] In the embodiment of the present application, as Figure 5 shown, clamping blocks 16 are fixedly connected to both sides of the bottom of the pull plate 13, and clamping grooves 15 adapted to the clamping blocks 16 are opened on both sides of the top of the fixed rod 10.

[0039] By adopting the above technical solution, rotating the pull plate 13 enables the pull plate 13 to drive the clamping blocks 16 to be misaligned with the clamping grooves 15, so that it is not necessary to continuously pull the pull plate 13 during disassembly.

[0040] In the embodiment of the present application, as Figures 2-3 shown, four groups of chutes 19 and sliders 18 are provided, and the four groups of chutes 19 and sliders 18 are distributed in an annular array.

[0041] By adopting the above technical solution, the coordinated cooperation of multiple groups of chutes 19 and sliders 18 makes the installation effect of the device better.

[0042] In the embodiment of the present application, as Figure 2 shown, the chute 19 is an L-shaped groove, and the chute 19 is adapted to the slider 18.

[0043] By adopting the above technical solution, the slider 18 can slide better along the chute 19.

[0044] In the embodiment of the present application, as Figure 1 shown, the base is an angle iron welded structure.

[0045] By adopting the above technical solution, the stability of the device is stronger.

[0046] In the embodiment of the present application, as Figure 1 shown, a control box 21 is fixedly connected to the outer surface of the base 1.

[0047] By adopting the above technical solution, the control box 21 can be used to more conveniently control the electrical appliances inside the device.

[0048] During use, when it is necessary to replace the electrode cap of the robotic welding tongs, the water fluid valve is closed to stop the inflow of cooling water. At the same time, the air fluid valve 5 is controlled to open. A one-way blowing system is formed between the air circuit system and the water inlet circuit by the air fluid valve 5 and the horizontal wafer check valve 6 for water in the air circuit. The gas is blown unidirectionally into the water inlet circuit through the horizontal wafer check valve 6 for water in the air circuit. The residual cooling water in the pipeline is blown into the return water circuit by air pressure to drain the remaining water in the robotic welding tongs. After waiting for five seconds, the air fluid valve 5 is closed, and then the replacement of the electrode cap of the robotic welding tongs begins. When it is necessary to replace the air fluid valve 5 or the horizontal wafer check valve 6 for water in the air circuit, the operator can pull the pull plate 13, so that the pull plate 13 pulls the positioning rod 12 out of the positioning hole 9 through the pull rod 11. At this time, the clamping block 16 just completely disengages from the clamping groove 15. Then the operator rotates the pull plate 13 so that the pull plate 13 can drive the clamping block 16 to be misaligned with the clamping groove 15. After that, the operator rotates the second connecting plate 8 so that the second connecting plate 8 can drive the slider 18 to slide along the sliding groove 19. When the slider 18 moves to the opening 22, the operator then pulls out the second connecting plate 8 downward, so that the separation of the first connecting plate 7 and the second connecting plate 8 can be started, and then the air fluid valve 5 or the horizontal wafer check valve 6 for water in the air circuit can be quickly replaced, thus greatly improving the practicability of the device.
