[0026] refer to Figure 1 A pull-out force testing tool for an annular welded part according to a preferred embodiment of the utility model will be described in detail below. The pull-out force testing tool for annular welded parts can be assembled with an annular welded part, and the part of the annular welded part where the weld is formed is defined as a processing part. The annular welded part also forms a force-applying part opposite to the processing part.

[0027] The pull-out force test tool for annular welded parts includes a tool body 10 and a clamping mechanism 20. The tool body 10 includes a first tool seat 11. The first tool seat 11 is used to connect with any one of the two suspension beams of a tensile testing machine, and the other suspension beam acts on the force-applying part. The clamping mechanism 20 includes a first clamping member 21. The first clamping member 21 is arranged on the first tool seat 11 and is detachably connected to the processing part of the annular welded part. When the processing part of the annular welded part is assembled with the first clamping member 21 and the force-applying part and the processing part are arbitrarily applied with tension, the side wall of the processing part facing the force-applying part abuts against the first clamping member 21 to perform pull-out force detection. Compared with the traditional test method, there is no need to introduce additional accessories, thereby eliminating the assembly process of the accessories covering the processing part, which is convenient to operate, saves operation time, and improves test efficiency.

[0028] refer to Figures 2 to 3 Preferably, the first fixing member 21 includes a pair of first fixing members 211, and the two first fixing members 211 of the pair are both detachably mounted on the first tooling seat 11. When the two first fixing members 211 are both mounted on the first tooling seat 11, the two first fixing members 211 jointly form a first fixing hole 21101, and the size of the first fixing hole 21101 is adapted to the size of the processing part. When the processing part is connected to the first fixing hole 21101, the first tooling seat 11 applies a pulling force to the processing part through the two first fixing members 211.

[0029] Furthermore, the first fixing member 21 also includes at least one pair of first fasteners 212, and the two first fasteners 212 of the pair detachably connect the first fixing members 211 to the first tooling seat 11 by respectively penetrating the two first fixing members 211 and being threadedly connected to the first tooling seat 11, so that the assembly of the annular welding part can be achieved by disassembling and assembling the first fixing members 211 and the first tooling seat 11.

[0030] Preferably, the first fastener 212 includes a first head 2121 and a first rod 2122, wherein the first head 2121 is formed by extending the first rod 2122. The first fastener 212 connects the first fastener 211 to the first tooling seat 11 in such a manner that the first head 2121 abuts against a side wall of the first fastener 211 away from the first tooling seat 11 and the first rod 2122 penetrates the first fastener 211 and is threadedly connected to the first tooling seat 11.

[0031] In one embodiment, the first fastener 212 connects the first clamping member 211 and the first tooling seat 11 by threaded connection with the first clamping member 211 and the first tooling seat 11 .

[0032] refer to Figure 4 In one embodiment, the first fixing member 21 is implemented as a slot formed in the first tooling seat 11. The two opposite ends of the slot are formed in the side wall of the first tooling seat 11, and the notch of the slot is formed in the end wall of the first tooling seat 11. The processing part moves into the slot in such a way that the notch of the slot is aligned with the notch of the slot and the portion of the annular welding part formed between the processing part and the force-applying part extends out of the two ends of the slot. When the processing part is engaged with the slot and the force-applying part and the processing part are subjected to any tension, the slot wall opposite to the notch abuts against the processing part.

[0033] refer to Figure 1 Further, the first tooling seat 11 has a first plug hole 1101, and any one of the two suspension beams of the tensile testing machine has a docking hole. When the first plug hole 1101 corresponds to a docking hole, a latch is simultaneously plugged into the first plug hole 1101 and the docking hole to assemble the first tooling seat 11 to the corresponding suspension beam, so that the first tooling seat 11 and the tensile testing machine can be quickly disassembled and assembled by pulling and inserting the latch.

[0034] refer to Figure 1 The tooling body 10 also includes a second tooling seat 12, which is arranged opposite to the first tooling seat 11 and is respectively mounted on the two suspension beams of the tensile testing machine. The clamping mechanism 20 includes a second clamping member 22, which is arranged on the second tooling seat 12 and is detachably connected to the force-applying portion of the annular weldment. After the processing portion and the force-applying portion of the annular weldment are respectively assembled with the first clamping member 21 and the second clamping member 22, the tensile testing machine uses the two suspension beams to assemble with the first tooling seat 11 and the second tooling seat 12 respectively and apply tensile force to the first tooling seat 11 and the second tooling seat 12 at will, so that the processing portion and the force-applying portion assembled on the first clamping member 21 and the second clamping member 22 can be applied with tensile force, so as to perform a pull-out force test.

[0035] refer to Figure 1 and Figure 3Preferably, the second fixing member 22 includes a connection space 221 and a plug-in connector 222, and the connection space 221 is formed in the second tooling seat 12. When the first tooling seat 11 and the second tooling seat 12 are arranged relative to each other, the connection space 221 faces the first tooling seat 11 and is connected to the outside. The size of the connection space 221 is adapted to the size of the force-applying portion, and the annular welding piece is assembled to the second tooling seat 12 in a manner that the force-applying portion is clamped in the connection space 221. The plug-in connector 222 locks the annular welding piece to the second tooling seat 12 by simultaneously plugging into the two opposite side walls of the connection space 221 formed by the second tooling seat 12 and penetrating the annular welding piece. The overall design is simple, and the annular welding piece and the first tooling seat 11 can be quickly disassembled and assembled.

[0036] In a modified embodiment, the connection space 221 is implemented as a socket. When the first tooling seat 11 and the second tooling seat 12 are arranged opposite to each other, one end of the socket faces the first tooling seat 11. After the processing portion of the annular welded piece is assembled with the first clamping member 21, one end of the annular welded piece away from the first clamping member 21 is inserted into the socket from the socket toward the end of the first tooling seat 11.

[0037] Preferably, the connection space 221 is implemented as a slot, and the two opposite ports of the slot are formed on the side wall of the second tooling seat 12, and the notch of the slot is formed on the end wall of the second tooling seat 12. When the first tooling seat 11 and the second tooling seat 12 are arranged opposite to each other, the notch faces the first tooling seat 11. The annular welded piece is assembled to the slot in a manner that the force-applying portion is engaged with the slot and the portion of the annular welded piece formed between the force-applying portion and the processing portion extends from the two ports. Compared with the previous embodiment, the size requirement of the second tooling seat 12 is smaller, and the tooling design cost is lower.

[0038] refer to Figure 4In one embodiment, the second fixing member 22 is implemented as a slot formed in the second tooling seat 12. The two opposite ports of the slot are formed on the side walls of the second tooling seat 12, and the notch of the slot is formed on the end wall of the second tooling seat 12. When the second tooling seat 12 is arranged opposite to the first tooling seat 11, the notch of the slot is located at an end of the second tooling seat 12 away from the first tooling seat 11. The force-applying portion moves into the slot in such a manner that the notch of the slot is aligned with the notch of the slot and the portion of the annular welding piece formed between the processing portion and the force-applying portion extends out of the two ports of the slot. When the force-applying portion is engaged with the slot and tension is applied to the force-applying portion and the processing portion, the slot wall opposite to the notch abuts against the force-applying portion.

[0039] refer to Figure 2 , Figure 5 and Figure 6 In another embodiment, the second fixing member 22 includes a pair of second fixing members 221A, and the two second fixing members 221A of the pair are both detachably mounted on the second tooling seat 12. When the two second fixing members 221A are both mounted on the second tooling seat 12, the two second fixing members 221A jointly form a second fixing hole 22101A, and the size of the second fixing hole 22101A is adapted to the size of the force-applying portion. When the force-applying portion is engaged with the second fixing hole 22101A, the second tooling seat 12 applies a pulling force to the force-applying portion through the two second fixing members 221A.

[0040] The second fixing member 22 also includes at least one pair of second fasteners 222A, and the two second fasteners 222A of a pair detachably connect the second fixing member 221A to the second tooling seat 12 by respectively penetrating the two second fixing members 221A and being threadedly connected to the second tooling seat 12, so that the assembly of the annular welding part can be achieved by disassembling and assembling the second fixing member 221A and the second tooling seat 12.

[0041] The second fastener 222A includes a second head 2221A and a second rod 2222A, and the second head 2221A is formed by extending the second rod 2222A. The second fastener 222A connects the second fastener 221A to the second tooling seat 12 in such a manner that the second head 2221A abuts against a side wall of the second fastener 221A away from the second tooling seat 12 and the second rod 2222A penetrates the second fastener 221A and is threadedly connected to the second tooling seat 12.

[0042] refer to Figure 1Further, the second tooling seat 12 has a second plug hole 1201, and the two suspension beams of the tensile testing machine both form the docking holes. After the first tooling seat 11 is assembled to the corresponding suspension beam by using the latch to be simultaneously inserted into the first plug hole 1101 and the docking hole formed in one of the suspension beams, the second plug hole 1201 is made to correspond to the docking hole of the other suspension beam, and the other latch is simultaneously inserted into the second plug hole 1201 and the corresponding docking hole to assemble the second tooling seat 12 to the corresponding suspension beam. In this process, the first tooling seat 11 and the second tooling seat 12 can be respectively assembled and disassembled from the two suspension beams by pulling and inserting the latch, which is convenient to operate.

[0043] Specifically, the processing part and the force-applying part of the annular weldment are respectively assembled on the first fixing member 21 and the second fixing member 22, based on the fact that the first tooling seat 11 and the second tooling seat 12 are respectively connected to the two suspension beams of the tensile testing machine, so that when a pulling force is applied to one of the suspension beams in a direction relatively away from the other suspension beam, the first tooling seat 11 and the second tooling seat 12 respectively transmit the force to the processing part and the force-applying part through the first fixing member 21 and the second fixing member 22, so as to perform a tensile force test on the annular weldment.

[0044] It is worth mentioning that when the size of the annular welded part is relatively large, the processed part of the annular welded part can be assembled on the first fixing member 21, and any one of the two suspension beams of the tensile testing machine is connected to the first tooling seat 11, while the other one grasps the force-applying part of the annular welded part through a clamp to perform a pull-out force test. At this time, the second tooling seat 12 and the second fixing member 22 may not be set.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
