[0030] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0031] Referring to Figures 1 to 4 The utility model provides a kind of plug-in pin mechanism of reassembly line, including transfer car body 1, bolt subassembly 2, moving assembly 3 and positioning assembly 4;

[0032] Mechanical product on reassembly line is mainly transported by transfer car body 1, transfer car body 1 drives mechanical product to move along the operation trend of reassembly line, sequentially moves to each operation station on assembly line, and completes the process movement of mechanical product;

[0033] Bolt subassembly 2 includes fixed structure 21, bolt body 22, auxiliary positioning structure 23 and rebound structure 24, fixed structure 21 is connected on transfer car body 1, bolt body 22 is movably connected with fixed structure 21 and can move along vertical direction relative to fixed structure 21, auxiliary positioning structure 23 is connected in lower part of bolt body 22, rebound structure 24 is movably connected with fixed structure 21 and bolt body 22 respectively;

[0034] Moving assembly 3 can move relative to transfer car body 1, and also can drive transfer car body 1 and bolt subassembly 2 to move synchronously after being connected with bolt subassembly 2, moving assembly 3 is provided with several pin hole positions 31 along length direction, in the moving process of moving assembly 3, bolt body 22 can be detachably connected with pin hole position 31, when bolt body 22 and pin hole position 31 are in the connection state, moving assembly 3, bolt subassembly 2 and transfer car body 1 move synchronously, when bolt body 22 and pin hole position 31 are in the separation state, moving assembly 3 moves relative to transfer car body 1, and transfer car body 1 remains stationary;

[0035] The positioning assembly 4 is fixed on the working plane of the reassembly line and cannot move relatively. The positioning assembly 4 can position the specific position of the working station. When the transfer trolley body 1 moves to the positioning assembly 4, it is equivalent to moving to the relative position of the working station corresponding to the positioning assembly 4. At this time, the positioning assembly 4 can be in sliding contact with the auxiliary positioning structure 23 and drive the auxiliary positioning structure 23 and the latch body 22 to be lifted to a height, so that the latch body 22 and the pin hole position 31 form a pre-separation. In the pre-separation state, the bottom end of the latch body 22 is not completely extracted from the pin hole position 31, but by forming a pre-separation state, it can help the moving assembly 3 to directly realize the pin extraction and insertion of the latch body 22 through its own movement.

[0036] The working principle of the latch insertion and extraction mechanism is as follows:

[0037] The transfer trolley body 1 needs to be moved from the previous working station to the next working station under the cooperation of the moving assembly 3. On the basis that the latch body 22 and the pin hole position 31 are in a connected state, the moving assembly 3 drives the transfer trolley body 1 to move towards the next working station. However, the length of the moving assembly 3 is limited, and it cannot move the same transfer trolley body 1 from the first working station to the last working station. The moving assembly 3 needs to repeatedly move to connect the pin hole position 31 at different positions with the latch body 22 connected to the same transfer trolley body 1, and move the transfer trolley body 1 to the next working station one by one, and so on.

[0038] When the transfer trolley body 1 moves to the positioning assembly 4 corresponding to a working station, the positioning assembly 4 can be in sliding contact with the auxiliary positioning structure 23 and drive the auxiliary positioning structure 23 and the latch body 22 to move upwards. At this time, the latch body 22 and the pin hole position 31 form a pre-separation state. Then the moving assembly 3 moves reversely relative to the working direction of the reassembly line, the purpose is to move the pin hole position 31 corresponding to the next working station to the lower side of the latch body 22. In the moving process, the moving assembly 3 can further drive the latch body 22 to move upwards and form a pin extraction with the corresponding pin hole position 31. Due to the existence of the rebound structure 24, the rebound structure 24 can exert a downward pressure on the latch body 22, and the top of the moving assembly 3 can form a supporting force on the bottom of the latch body 22, so that the bottom of the latch body 22 and the top of the moving assembly 3 form a sliding contact in the moving process of the moving assembly 3.

[0039] When the next work station corresponding to the pin hole position 31 moves to the lower side of the pin body 22, the support force of the moving assembly 3 to the pin body 22 becomes non-existent, the pin body 22 can be driven by the rebound structure 24 to move downward, inserted into the pin hole position 31, so that the pin body 22 and the pin hole position 31 form a pin, and then the moving assembly 3 can drive the pin assembly 2 and the transfer car body 1 to move to the next work station, and repeat the above steps to complete the process movement of the mechanical product.

[0040] The overall structure of the plug-in and plug-out pin mechanism of the reassembly line is simpler, and the plug-in and plug-out operations can be more automated, improving work efficiency and reducing the work pressure of the operator, and being safer.

[0046] In the embodiment, the first matching part 2211 is preferably a plane or an arc surface obliquely arranged, and the second matching part 311 is located at the same end as the first matching part 2211,

[0047] When the moving assembly 3 moves reversely relative to the working direction of the reassembly line, the second matching part 311 can shovel the first matching part 2211, further driving the plug body 22 to move upward and form a disconnection with the corresponding pin hole position 31, and due to the existence of the rebound structure 24, the rebound structure 24 can exert a downward pressure on the plug body 22, while the top of the moving assembly 3 supports the bottom of the plug body 22, so that the bottom of the plug body 22 and the top of the moving assembly 3 form a sliding contact during the movement of the moving assembly 3.

[0048] When the next working position corresponding to the pin hole position 31 moves to the lower side of the plug body 22, the support force of the moving assembly 3 on the plug body 22 becomes non-existent, the plug body 22 can be driven by the rebound structure 24 to move downward and be inserted into the pin hole position 31, so that the plug body 22 and the pin hole position 31 form a plug, at this time, the bottom of the plug rod 221 away from the end of the first matching part 2211 and the end of the pin hole position 31 away from the second matching part 311 are not in a matching relationship, the plug rod 221 can be directly inserted into the inside of the pin hole position 31 to form a plug, and the two will not be separated.
