Description

Technical Field

[0001] The present application relates to the technical field of welding tooling, and in particular to an error-proof tooling for welding and forming a filling valve. Background Art

[0002] The filling valve is a valve seat used on the aluminum tube of automobile air conditioning refrigeration. When installing the filling valve, first open an installation port at the corresponding position of the aluminum tube, then align the filling valve at the installation port, and finally seal and weld the filling valve to the edge of the installation port. In the actual welding process, the filling valve and the installation port need to be precisely docked to ensure the welding effect, and then heat and melt the filling valve and the aluminum tube at the docking point for welding.

[0003] However, during the welding process, the melting of the filling valve and the aluminum tube may cause the welding liquid to flow into the installation port, causing the installation port to be blocked, and the filling valve and the aluminum tube cannot be connected, resulting in the pipeline being unusable after the filling valve is installed. Utility Model Content

[0004] The purpose of the present application is to provide a filling valve welding forming error-proof tooling, which is used to solve the problem in the related art that after the filling valve is installed, the installation port is blocked, resulting in the filling valve and the aluminum tube being unable to be connected and used.

[0005] The present application provides a filling valve welding forming error-proofing tooling that adopts the following technical solution:

[0006] A filling valve welding forming error-proof tooling, comprising:

[0007] An ejector pin, which can penetrate the mounting opening and seal the mounting opening;

[0008] A support frame, wherein a sliding groove and a moving groove are provided on the support frame, and the sliding groove is communicated with the moving groove;

[0009] A proximity switch, wherein the proximity switch is mounted on the support frame;

[0010] A welding rod, wherein the welding rod is fixedly connected to the ejector pin, the welding rod is slidably connected in the sliding groove, the welding rod can abut against the filling valve, and the welding rod is provided with an abutment rod, the abutment rod is accommodated in the movable groove, and the abutment rod can abut against the proximity switch.

[0011] By adopting the above technical solution, an installation port is opened on the aluminum tube, and the filling valve is aligned at the installation port. It is necessary to seal and weld the filling valve to the edge of the installation port. When the welding rod slides in the sliding groove and makes the abutting rod abut against the proximity switch, the welding rod abuts against the filling valve, and the ejector penetrates and blocks the installation port. At this time, the green light of the indicator light electrically connected to the proximity switch lights up. According to the situation that the green light is on, the operator can start the welding operation and weld the joint between the filling valve and the aluminum tube. The ejector is a tungsten steel ejector with a high melting point and will not melt at the melting point of the aluminum tube. At this time, the welding rod abuts against the filling valve to fix the position of the filling valve. The relative position of the filling valve and the aluminum tube will not change. The ejector penetrates and blocks the installation port. The welding liquid generated by welding will not flow into the installation port to completely block the installation port and cause the filling valve to be blocked. The filling valve cannot be connected with the aluminum tube, and it will not flow into the aluminum tube through the installation port to cause the aluminum tube to be blocked, thereby solving the problem that the aluminum tube and the filling valve cannot be used after the filling valve is installed.

[0012] When the welding is completed and cooled, the abutment rod is moved to disengage from the proximity switch, the red indicator light electrically connected to the proximity switch lights up, the welding rod is moved, the ejector pin is removed from the installation port, and the welding rod is disengaged from the step surface of the filling valve. At this time, the aluminum tube with the filling valve welded thereon can be removed.

[0013] Optionally, the diameter of the welding rod is greater than the diameter of the ejector pin, and when the welding rod abuts against the inner wall of the filling valve, the ejector pin penetrates and blocks the installation port.

[0014] By adopting the above technical solution, the diameter of the welding rod is larger than the diameter of the ejector pin. When the welding rod moves downward and abuts against the step surface in the filling valve, the ejector pin with a smaller diameter can directly pass through the filling valve and abut against the installation port to seal the installation port.

[0015] Optionally, the movable groove includes a transverse groove and a vertical groove, the transverse groove and the vertical groove are connected to each other, and the proximity switch is installed on a side of the support frame close to the transverse groove.

[0016] By adopting the above technical solution, the horizontal groove and the vertical groove are connected to each other, the abutment rod moves upward in the vertical groove to disengage the ejector pin from the installation opening, and the abutment rod moves in the horizontal groove to abut against the proximity switch to start welding.

[0017] Optionally, it further includes a handle and an elastic member, wherein the handle is fixedly connected to the welding rod, and the elastic member connects the handle and the support frame.

[0018] By adopting the above technical solution, the elastic member connects the handle and the support frame, and the welding rod moves upward or downward under the elastic action of the elastic member.

[0019] Optionally, an indicator light is also included, and the indicator light is electrically connected to the proximity switch.

[0020] By adopting the above technical solution, the indicator light is electrically connected to the proximity switch. When the abutment rod abuts the proximity switch, the indicator light turns green. When the abutment rod is separated from the proximity switch, the indicator light turns red.

[0021] Optionally, it further includes a support block and a base, the support frame is fixed on the base, the support block is installed on the base, a first groove is opened on the support block, and the aluminum tube is placed in the first groove.

[0022] By adopting the above technical solution, the support block is provided with a first groove, and the aluminum tube is placed in the first groove, which stabilizes the aluminum tube.

[0023] Optionally, it further includes a compression block, on which a second groove is provided. When the compression block abuts against the supporting block, the second groove abuts against the aluminum tube.

[0024] By adopting the above technical solution, a second groove is provided on the compression block, the compression block abuts against the support block, and the second groove abuts against the aluminum tube, thereby stabilizing the aluminum tube.

[0025] Optionally, a clamp is further included, wherein the clamp is installed on the support block and can abut against the compression block.

[0026] By adopting the above technical solution, when the clamp abuts against the pressing block, it stabilizes the aluminum tube. When the clamp is separated from the pressing block, the aluminum tube can be removed from the supporting block.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The aluminum tube is fixed in the first groove of the support block. The clamp presses the pressing block so that the second groove of the pressing block abuts against the aluminum tube. An installation port is opened on the aluminum tube. The filling valve is aligned at the installation port. The filling valve and the edge of the installation port need to be sealed and welded. When the welding rod slides in the sliding groove and the abutting rod abuts against the proximity switch, the welding rod abuts against the filling valve, and the ejector penetrates and blocks the installation port. At this time, the green light of the indicator light electrically connected to the proximity switch lights up. The operator can start the welding operation according to the situation of the green light, and weld the joint between the filling valve and the aluminum tube. The ejector is a tungsten steel ejector with a high melting point, and it will not melt at the melting point of the aluminum tube. At this time, the welding rod is in contact with the filling valve to fix the position of the filling valve. The relative position of the filling valve and the aluminum tube will not change. The ejector pin penetrates and blocks the installation port. The welding liquid produced by welding will not flow into the installation port to completely block the installation port and cause the filling valve to be blocked. The filling valve and the aluminum tube cannot be connected, and the filling liquid will not flow into the aluminum tube through the installation port to cause the aluminum tube to be blocked, thereby solving the problem that the aluminum tube and the filling valve cannot be used after the filling valve is installed.

[0029] When the welding is completed and cooled, the moving abutment rod disengages from the proximity switch, the red indicator light electrically connected to the proximity switch lights up, the welding rod bounces upward under the elastic action of the spring, the ejector pin is removed from the installation port, the welding rod disengages from the step surface of the filling valve, and the clamp is released to disengage the pressing block from the aluminum tube. At this time, the aluminum tube welded with the filling valve can be removed from the support block.

[0030] 2. The welding rod moves downward and contacts the step surface inside the filling valve. On the one hand, it prevents the welding rod from approaching the installation port, and on the other hand, it stabilizes the filling valve in the horizontal direction to prevent the relative position of the filling valve and the aluminum tube from changing.

[0047] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0048] The embodiment of the present application discloses a filling valve welding forming error-proofing tool.

[0049] Reference Figure 1 , Figure 2 and Figure 3 A filling valve welding forming error-proofing tooling includes a ejector pin 10, a support frame 20, a proximity switch 30, a welding rod 40, a handle 50, an elastic member 60, an indicator light 70, a support block 80, a base 90, a pressing block 100 and a clamp 110. The welding rod 40 is slidably connected to the sliding groove 21 on the support frame 20, the welding rod 40 can abut against the filling valve 120, the ejector pin 10 is fixedly connected to the welding rod 40, the ejector pin 10 can penetrate the installation port 131 and block the installation port 131, an abutting rod is installed on the welding rod 40, the abutting rod is slidably connected to the moving groove 22 on the support frame 20, the proximity switch 30 is electrically connected to the indicator light 70, when the abutting rod abuts against the proximity switch 30, the indicator light 70 is turned on, the welding rod 40 abuts against the filling valve 120 and the ejector pin 10 penetrates and blocks the installation port 131.

[0050] An installation port 131 is provided on the aluminum tube 130, and the filling valve 120 is aligned with the installation port 131. The filling valve 120 needs to be sealed and welded to the edge of the installation port 131. When the welding rod 40 slides in the sliding groove 21 and makes the abutting rod abut against the proximity switch 30, the welding rod 40 abuts against the filling valve 120, and the ejector pin 10 penetrates and blocks the installation port 131. At this time, the indicator light 70 electrically connected to the proximity switch 30 lights up green. The operator can start the welding operation according to the situation that the green light is on, and weld the joint between the filling valve 120 and the aluminum tube 130. The ejector pin 10 is a tungsten steel ejector pin 10 with a high melting point, and will not melt at the melting point of the aluminum tube 130. At this time, the welding rod 40 is in contact with the filling valve 120 to fix the position of the filling valve 120. The relative position of the filling valve 120 and the aluminum tube 130 will not change. The ejector pin 10 penetrates and blocks the mounting port 131. The welding liquid generated by welding will not flow into the mounting port 131 to completely block the mounting port 131 and cause the filling valve 120 to be blocked. The filling valve 120 and the aluminum tube 130 cannot be connected, and the filling valve 120 will not flow into the aluminum tube 130 through the mounting port 131 to cause the aluminum tube 130 to be blocked, thereby solving the problem that the aluminum tube 130 and the filling valve 120 cannot be used after the filling valve 120 is installed.

[0051] When the welding is completed and the temperature has cooled, the abutment rod is moved to disengage from the proximity switch 30, the indicator light 70 electrically connected to the proximity switch 30 lights up red, the welding rod 40 is moved, the ejector pin 10 is taken out from the mounting port 131, and the welding rod 40 is disengaged from the step surface 121 of the filling valve 120. At this time, the aluminum tube 130 welded with the filling valve 120 can be removed.

[0052] Reference Figure 2 and Figure 4 The welding rod 40 is fixedly connected to the ejector pin 10. The diameter of the welding rod 40 is larger than that of the ejector pin 10. When the welding rod 40 abuts against the inner wall of the filling valve 120, the ejector pin 10 penetrates and blocks the installation port 131. The diameter of the filling valve 120 is larger than that of the installation port 131 and the filling valve 120 itself is provided with a step surface 121. When the welding rod 40 moves downward and is inserted into the filling valve 120 and abuts against the step surface 121 in the filling valve 120, the ejector pin 10 with a smaller diameter can directly penetrate the filling valve 120 and abut against the installation port 131 and block the installation port 131.

[0053] Reference Figure 3 The specific structure of the movable groove 22 and the specific connection relationship between it and the proximity switch 30 are as follows: the movable groove 22 includes a transverse groove 221 and a vertical groove 222, the transverse groove 221 and the vertical groove 222 are connected to each other, the transverse groove 221 and the vertical groove 222 are respectively connected to the sliding groove 21, and the proximity switch 30 is installed on the support frame 20 and close to one side of the transverse groove 221.

[0054] The abutment rod is fixed on the welding rod 40. When the welding rod 40 moves downward in the sliding groove 21, the abutment rod moves downward in the vertical groove 222. When the abutment rod reaches the connecting point of the transverse groove 221 and the vertical groove 222, the welding rod 40 abuts against the step surface 121 in the filling valve 120, and the ejector pin 10 penetrates and blocks the installation port 131. At this time, the welding rod 40 is rotated horizontally to move the abutment rod in the transverse groove 221. When the abutment rod abuts against the proximity switch 30 at one end of the transverse groove 221, the green light of the indicator light 70 lights up, which proves that the welding rod 40 and the ejector pin 10 are fixed and welding can begin.

[0055] After welding is completed and cooled, the welding rod 40 is rotated to disengage the abutment rod from the proximity switch 30, the indicator light 70 turns red, the abutment rod moves in the horizontal groove 221 to the connection between the horizontal groove 221 and the vertical groove 222, the welding rod 40 is moved upward, and the abutment rod moves in the vertical groove 222 to disengage the welding rod 40 from the filling valve 120. At this time, the aluminum tube 130 can be removed.

[0056] Reference Figure 1 , Figure 2 and Figure 3The lower end of the welding rod 40 is fixedly connected to the ejector pin 10, and the upper end is fixedly connected to the handle 50. The elastic member 60 is located between the handle 50 and the support frame 20, and the elastic member 60 connects the handle 50 and the support frame 20. The elastic member 60 can be a spring 61, and the handle 50 is provided with a heat insulating material. When the welding rod 40 moves downward in the sliding groove 21, the spring 61 is compressed, and the abutment rod moves downward in the vertical groove 222. When the welding rod 40 abuts against the step surface 121 in the filling valve 120, the ejector pin 10 penetrates and blocks the installation port 131. At this time, the welding rod 40 is rotated horizontally to make the abutment rod move in the horizontal groove 221. When the abutment rod abuts against the proximity switch 30 at one end of the horizontal groove 221, the green light of the indicator light 70 is on, which proves that the welding rod 40 and the ejector pin 10 are fixed and welding can be started. During this process, the spring 61 is always in a compressed state.

[0057] After welding is completed and cooled, the welding rod 40 is rotated to disengage the abutment rod from the proximity switch 30, the indicator light 70 turns red, and the abutment rod moves in the horizontal groove 221 to the connecting point between the horizontal groove 221 and the vertical groove 222. The welding rod 40 moves upward under the elastic action of the spring 61, and the abutment rod moves upward in the vertical groove 222, so that the welding rod 40 is disengaged from the filling valve 120. At this time, the aluminum tube 130 can be removed.

[0058] Reference Figure 1 and Figure 2 The support block 80 and the support frame 20 are both located above the base 90 and are installed on the base 90. The support block 80 is provided with a first groove 81, and the aluminum tube 130 is placed on the first groove 81. There are multiple support blocks 80, and the height angles are set differently. In accordance with the shape and angle setting of the aluminum tube 130, the support block 80 is provided with a first groove 81, and the aluminum tube 130 is placed in the first groove 81. The aluminum tube 130 is positioned and fixed to facilitate the subsequent welding of the filling valve 120 and the aluminum tube 130.

[0059] Reference Figure 1 and Figure 2 , the compression block 100 is located above the aluminum tube 130, and the compression block 100 has a second groove 101. When the compression block 100 abuts against the support block 80, the second groove 101 abuts against the aluminum tube 130. After the aluminum tube 130 is placed in the first groove 81, the second groove 101 in the compression block 100 abuts against the upper end surface of the aluminum tube 130. At this time, the compression block 100 matches the shape of the support block 80 and abuts against the support block 80. The compression block 100 fixes the aluminum tube 130, and the first groove 81 and the second groove 101 fix the aluminum tube 130 to prevent the aluminum tube 130 from moving during the welding process and affecting the docking position of the filling valve 120 and the aluminum tube 130.

[0060] Reference Figure 1 and Figure 2The clamp 110 is located above the support block 80, and the clamp 110 is installed on the support block 80. The clamp 110 can abut against the compression block 100. When the compression block 100 abuts against the support block 80, the handle 50 of the clamp 110 is pushed backward, driving the clamp block 110 to squeeze the compression block 100 downward, thereby achieving the purpose of tightening the compression block 100.

[0061] The implementation principle of the filling valve welding forming error-proofing tooling of this embodiment is as follows: the aluminum tube 130 is fixed in the first groove 81 of the support block 80, the clamp 110 presses the pressing block 100 so that the second groove 101 of the pressing block 100 abuts against the aluminum tube 130, the aluminum tube 130 is provided with an installation port 131, the filling valve 120 is aligned at the installation port 131, and the filling valve 120 needs to be sealed and welded to the edge of the installation port 131. When the welding rod 40 is in the sliding groove 21 When the abutment rod 10 slides inwardly and abuts against the proximity switch 30, the welding rod 40 abuts against the filling valve 120, and the ejector pin 10 penetrates and blocks the installation port 131. At this time, the green light of the indicator light 70 electrically connected to the proximity switch 30 lights up. The operator can start the welding operation according to the situation that the green light is on, and weld the joint between the filling valve 120 and the aluminum tube 130. The ejector pin 10 is a tungsten steel ejector pin 10 with a high melting point and will not melt at the melting point of the aluminum tube 130. At this time, the welding rod 40 is in contact with the filling valve 120 to fix the position of the filling valve 120. The relative position of the filling valve 120 and the aluminum tube 130 will not change. The ejector pin 10 penetrates and blocks the mounting port 131. The welding liquid generated by welding will not flow into the mounting port 131 to completely block the mounting port 131 and cause the filling valve 120 to be blocked. The filling valve 120 and the aluminum tube 130 cannot be connected, and the filling valve 120 will not flow into the aluminum tube 130 through the mounting port 131 to cause the aluminum tube 130 to be blocked, thereby solving the problem that the aluminum tube 130 and the filling valve 120 cannot be used after the filling valve 120 is installed.

[0062] When the welding is completed and cooled, the moving abutment rod is disengaged from the proximity switch 30, the indicator light 70 electrically connected to the proximity switch 30 lights up red, the welding rod 40 bounces upward under the elastic action of the spring 61, the ejector pin 10 is removed from the mounting port 131, the welding rod 40 is disengaged from the step surface 121 of the filling valve 120, and then the clamp 110 is released to disengage the pressing block 100 from the aluminum tube 130. At this time, the aluminum tube 130 welded with the filling valve 120 can be removed from the support block 80.
