[0001] The utility model relates to the technical field of machining of vehicle body parts, and particularly relates to a large machining fixture replacement and transfer mechanism. Background Art

[0002] Integrally die-cast vehicle bodies are the products of vehicle lightweighting, which are characterized by large size and heavy weight. Their geometric dimensions generally reach 1500mm×1600mm×700mm, and the weight reaches more than 50 Kg. Correspondingly, the machining fixtures also become large and heavy, with geometric dimensions usually reaching more than 3000mm×2000mm and the weight reaching more than 1000 Kg.

[0003] At present, by setting the fixture as a combination of a fixture parent body and a fixture sub-body, only the fixture sub-body needs to be replaced when replacing the fixture, and there is no need to replace the entire fixture, which can improve the fixture replacement efficiency to a certain extent. However, the fixture sub-body is heavy, and when replacing it, it needs to be lifted and replaced through the top door of the machine tool, still having problems such as large operation difficulty, low efficiency, and high danger coefficient.

[0041] As Figures 1 - 5 shown, this embodiment provides a large-scale machining fixture replacement and transfer mechanism, including a frame 1, a tray 2, and a folding assembly 3. The tray 2 is used to support the fixture sub-body 42, the frame 1 is used to install the folding assembly 3, and the folding assembly 3 is used to move the position of the tray 2. When the folding assembly 3 is folded on the frame 1, the tray 2 is located on the frame 1. When the folding assembly 3 is unfolded, the folding assembly 3 sends the tray 2 from the frame 1 into the machine tool 5. In this embodiment, the frame 1 is arranged at the rear door 51 position of the machine tool 5, and the frame 1 straddles the chip removal mechanism 52 of the machine tool 5. Without conflicting with the chip removal mechanism 52, the fixture sub-body 42 on the tray 2 is sent into the machine tool 5 through the folding assembly 3 for replacement. It occupies a small space, can adapt to the situation where a forklift cannot directly reach, and there is no need to hoist through the top door of the machine tool 5. The operation is simple, the efficiency is high, and the risk factor is low.

[0042] In this embodiment, the folding assembly 3 includes a first fixing member 31, a second fixing member 32, and a connecting member 33. The first fixing member 31 is fixedly installed on the top of the frame 1, the tray 2 is fixedly connected to the second fixing member 32, one end of the connecting member 33 is slidably connected to the first fixing member 31, and the other end is slidably connected to the second fixing member 32. When in use, the tray 2 can be moved by sliding the second fixing member 32, further reducing the operation difficulty. And by setting the connecting member 33, the lengths of the first fixing member 31 and the second fixing member 32 can be reduced, so as to effectively reduce the space occupied when the folding assembly 3 is folded on the premise of ensuring the moving range of the tray 2. In some other embodiments, the folding assembly 3 can also be provided with structures such as a cylinder, a motor plus a reciprocating lead screw, etc.

[0043] In this embodiment, the first fixing member 31, the second fixing member 32, and the connecting member 33 are all set as slide rail groups, and the slide rail groups slide more smoothly. The connecting member 33 is slidably disposed inside the first fixing member 31, and the second fixing member 32 is slidably disposed inside the connecting member 33. In some other embodiments, the first fixing member 31, the second fixing member 32, and the connecting member 33 may also be set as slider structures with chutes, etc.

[0044] In this embodiment, the tray 2 includes a bracket 21 and a plurality of support cross beams 22. A gap area is formed between adjacent support cross beams 22, and the support cross beams 22 are fixedly installed on the bracket 21. When the forklift places the fixture sub - body 42 on the tray 2, the fork of the forklift can be placed into the gap area, which is convenient for cooperation with the forklift.

[0045] In this embodiment, a first limiting member 221 is provided at the end of the support cross beam 22. The first limiting member 221 is used to limit the movement of the fixture sub - body 42 to prevent the fixture sub - body 42 on the tray 2 from moving randomly.

[0046] In this embodiment, a pin hole 222 is formed at the end of the support cross beam 22, and a locking pin 11 is provided on the frame body 1. When the folding assembly 3 is folded on the frame body 1, the locking pin 11 is inserted into the pin hole 222 to lock the position of the support cross beam 22, so as to fix the position of the tray 2. The locking pin 11 is threadedly connected to the frame body 1, and a handle 12 for facilitating the rotation of the locking pin 11 is provided at the outer end of the locking pin 11. By rotating the locking pin 11 through the handle 12, the locking pin 11 is inserted into the pin hole 222. In this embodiment, a second limiting member 13 is provided on the frame body 1. When the tray 2 exits from the machine tool 5, the second limiting member 13 limits the tray 2 to facilitate inserting the locking pin 11 into the pin hole 222.

[0047] In this embodiment, as Figure 1 and Figure 5 shown, a braking member 6 is provided between the tray 2 and the frame body 1. When the folding assembly 3 is unfolded, the braking member 6 is used to fix the position of the tray 2. The braking member 6 is set as a limiting plate. After the tray 2 enters the preset position, both ends of the limiting plate are respectively engaged with the tray 2 and the frame body 1, thereby fixing the position of the tray 2.

[0048] In this embodiment, an adjusting bolt 14 is provided at the bottom of the support column of the frame body 1. The adjusting bolt 14 can adjust the overall height and level within a certain range and can adapt to different ground conditions in the workshop. A floor bolt 15 is provided at the bottom of the adjusting bolt 14, and the floor bolt 15 is fixedly connected to the ground to prevent the adjusting bolt 14 from damaging the ground.

[0049] In this embodiment, a grid platform 16 for storing tools is provided on the frame body 1, which is convenient for placing operating tools.

[0050] In this embodiment, a position sensor 17 is provided on the frame 1. When the tray 2 moves to a preset position, the position sensor 17 emits a signal for replacing the fixture sub-body 42. For example, it can be connected to an industrial computer to receive the signal through the industrial computer. It can also be connected to a horn, a speaker, etc. to directly notify the operator.

[0051] Working principle:

[0052] First, push the tray 2 to the preset position inside the machine tool 5 and fix the position of the tray 2 through the braking member 6.

[0053] Then, the position sensor 17 emits a signal for replacing the fixture sub-body 42. The operator starts the machine tool 5, and the Z-axis of the machine tool 5 hoists the fixture sub-body 42 onto the tray 2 and makes the fixture sub-body 42 abut against the first limiting member 221.

[0054] Subsequently, remove the braking member 6 and pull out the tray 2 from the machine tool 5 by moving the second fixture. After exchanging the new fixture sub-body 42 with the fixture sub-body 42 to be replaced on the tray 2 through tools such as a forklift, push the new fixture sub-body 42 into the preset position inside the machine tool 5.

[0055] After that, the operator starts the machine tool 5, and the Z-axis of the machine tool 5 hoists the fixture sub-body 42 onto the fixture main body 41 and automatically locks it through the machine tool 5 to complete the replacement of the fixture sub-body 42.

[0056] Finally, pull out the tray 2 from the machine tool 5 and lock it by inserting the locking pin 11 into the pin hole 222.

[0057] The above embodiments are only preferred embodiments cited to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
