[0031] Example:

[0032] A welding tool to prevent missing or wrong installation, such as Figure 2 As shown, it includes a base 1 and support columns 2. Two support columns 2 are vertically arranged at two ends of the base 1. A support bottom plate 3 is welded to the upper ends of the support columns 2.

[0033] like Figure 2 and 3As shown, a limiting hole 4 is provided on the supporting base plate 3, and an air outlet baffle 38 is embedded in the limiting hole 4. A first limiting seat 5 and a second limiting seat 6 are slidably connected to the supporting base plate 3. The first limiting seat 5 and the second limiting seat 6 are respectively arranged on both sides of the limiting hole 4. A limiting plate 7 is installed on the side of the first limiting seat 5 and the second limiting seat 6 close to the limiting hole 4. The limiting plate 7 is arc-shaped, and the two limiting plates 7 are clamped at both ends of the air outlet baffle 38.

[0034] like Figure 2 and 3 As shown, the first limit seat 5 includes a bracket 51 welded on the supporting base plate 3, a connecting plate 52 slidably connected to the bracket 51, the limit plate 7 is connected to the connecting plate 52 by bolts, a guide groove 8 is arranged below the connecting plate 52, and a guide rail 9 is fixedly connected to the bracket 51, and the guide rail 9 slides in the guide groove 8.

[0035] like Figure 2 and 3 As shown, a positioning seat 10 is welded on the bracket 51, and a rodless cylinder 11 is connected to the positioning seat 10 by bolts. The end of the rodless cylinder 11 close to the limit plate 7 is connected to a fixing block 12, and the rodless cylinder 11 is connected to the limit plate 7 through the fixing block 12. A connecting seat 13 is installed at the end of the rodless cylinder 11 away from the first limit seat 5, and a clamp 14 is installed on the connecting seat 13, and the clamp 14 is connected to the piston rod of the rodless cylinder 11.

[0036] like Figure 2 and 3 As shown, the staff first places the air intake baffle 35 above the air outlet baffle 38, and then adjusts the connecting plate 52 to slide along the guide groove 8 toward the air intake baffle 35. After that, the clamp 14 pushes the piston rod of the rodless cylinder 11 to be pre-clamped on the outer wall of the air intake baffle 35. Then, the switch of the rodless cylinder 11 is turned on, and the rodless cylinder 11 drives the limit plate 7 to automatically clamp on the outer wall of the air intake baffle 35.

[0037] like Figure 3 and 4As shown, the staff adjusts the second limit seat 6 to press against the other side of the air intake partition 35. The second limit seat 6 includes an "L"-shaped support plate 61 and a slideway 62. The horizontal section of the "L"-shaped support plate 61 is welded to the support base plate 3, and the slideway 62 is disassembled and connected to the support base plate 3 by bolts. A rodless cylinder 2 15 is installed on one side of the support plate 61, and a clamp 2 16 is installed on the other side. A through hole 17 is opened on the support plate 61. The piston rod of the rodless cylinder 2 15 is slidably penetrated in the through hole 17. The end of the piston rod of the rodless cylinder 2 15 is connected to the clamp 2 16 through the double ear plate 2102. A sliding plate 18 is slidably provided on the slideway 62. The limit plate 7 is installed on the sliding plate 18. The limit plate 7 is connected to a push plate 19. The end of the piston rod of the rodless cylinder 2 15 is connected to the push plate 19.

[0038] like Figure 3 As shown, the clamp 2 16 first pushes the push plate 19 to slide in the direction close to the air intake baffle 35, so that the limit plate 7 on the sliding plate 18 is pre-clamped on the outer wall of the air intake baffle 35, and then the rodless cylinder 2 15 drives the limit plate 7 to automatically clamp on the outer side of the air intake baffle 35, thereby effectively fixing the position of the air intake baffle 35.

[0039] like Figure 2 and 3 As shown, a protective plate 20 is detachably connected to the fixed block 12 and the push plate 19. The protective plate 20 is "L"-shaped and is installed above the piston rods of the rodless cylinder 11 and the rodless cylinder 2 15. The protective plate 20 can protect the piston rods of the rodless cylinder 11 and the rodless cylinder 2 15 to prevent the piston rods from being broken by foreign objects during operation.

[0040] like Figure 1 and 4 As shown, since vibration will occur during the welding process, in order to further stably weld the air inlet baffle 35 above the air outlet baffle 38, a pressing assembly 21 is also arranged on the limiting plate 7, and four pressing assemblies 21 are symmetrically arranged along the central axis of the air inlet baffle 35.

[0041] like Figure 4 As shown, the pressing assembly 21 includes a connecting base plate 2101 and a double ear plate 2102 which are detachably connected to the limit plate 7. The double ear plate 2102 is vertically welded to the connecting base plate 2101. A rotating shaft 22 is rotatably penetrated on the double ear plate 2102. A pressing plate 23 is rotatably sleeved on the rotating shaft 22. The pressing plate 23 is tightly pressed against the top of the air intake partition 35. A driving cylinder 24 is connected to the connecting base plate 2101.

[0042] like Figure 4As shown, the pressing plate 23 is in a stepped shape, and includes a first step 2301 and a second step 2302. The second step 2302 is connected to the lower part of the first step 2301 through a connecting member, and the second step 2302 abuts against the upper part of the air intake partition 35. Through the arrangement of the first step 2301 and the second step 2302, the piston rod of the driving cylinder 24 extends upward, pushing the pressing plate 23 to be pressed against the upper part of the air intake partition 35.

[0043] like Figure 5 As shown, a sliding seat 25 is slidably connected to the support base plate 3, a positioning block 26 is installed on the sliding seat 25, a sensor 27 is installed in the positioning block 26, the sensor 27 is connected to the external power supply system through a wire, the output end of the sensor 27 is in contact with the mixing board 37, and the sensor 27 is also connected to a display light 28 through a wire. The staff can judge that the installation direction of the mixing board 37 is correct through the display light 28, and the setting of the sensor 27 can improve the convenience of the staff to judge the installation direction.

[0044] like Figure 5 and 6 As shown, in order to improve the convenience of adjusting the positioning block 26 to abut against the mixing plate 37 when the staff processes different mixers. A sliding groove 29 is provided on the sliding seat 25, and a slide rail 30 is installed on the supporting base plate 3, and the sliding groove 29 slides in cooperation with the slide rail 30. A guide plate 31 is also connected to the sliding seat 25, and a connecting sleeve 33 is penetrated at the end of the guide plate 31. A driving cylinder 34 is detachably connected to the supporting base plate 3, and a piston rod of the driving cylinder 34 is penetrated in the connecting sleeve 33. The length direction of the piston rod of the driving cylinder 34 is parallel to the length direction of the guide rail 9, so that the driving cylinder 34 efficiently drives the sliding seat 25 to slide along the sliding groove 29.

[0045] Specific implementation process: First, the outlet baffle 38 to be welded is embedded into the limiting hole 4, and then the guide plate 36 and the mixing plate 37 are welded above the outlet baffle 38. The staff turns on the switch of the driving cylinder 34, and the driving cylinder 34 pushes the sliding seat 25 to slide along the slide rail 30 through the guide plate 31, so that the positioning block 26 is close to the mixing plate 37. At this time, the sensor 27 is in contact with the mixing plate 37. When the installation direction of the mixing plate 37 is correct, the display light 28 connected to the sensor 27 lights up, so that the staff knows that the mixing plate 37 is installed in the correct direction.

[0046] Then, the staff installs the air intake baffle 35 on the guide plate 36, and adjusts the clamp 1 14 and the clamp 2 16 so that the limit plates 7 on both sides are respectively pressed against the two sides of the air intake baffle 35 to achieve pre-clamping of the air intake baffle 35, and then adjusts the rodless cylinder 1 11 and the rodless cylinder 2 15 so that the limit plates 7 on both sides are automatically clamped on the outer side wall of the air intake baffle 35. After that, the staff adjusts the pressing assembly 21 to press on the top of the air intake baffle 35, and the driving cylinder 2 24 drives the pressing plate 23 to rotate around the rotating shaft 22, so that the pressing plate 23 is pressed on the top of the air intake baffle 35, and the purpose of positioning the air intake baffle 35 is achieved.

[0047] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention.
