Detailed Description

The technical scheme of the utility model is further described in detail in the following with the accompanying drawings of the specification.

As shown in fig. 1 to 5, the quick tool changing device of the present invention includes a motherboard 1 and a daughter board 2. The daughter board 2 is fixed with the part to be processed, the mother board 1 is connected with the machine tool workbench 3, the mother board 1 can be respectively matched with the daughter boards 2 for use, the part to be processed is placed on the daughter board 2 for fixation before processing, and when the part needs to be replaced, the working state of the quick connection of the universal interface between the mother board 1 and the daughter board 2 is utilized.

The part clamp is replaced in a short time, so that the part can be fixed without occupying the machining time, and the machining efficiency of the machine tool is greatly improved.

4 round holes are designed on the motherboard 1, the number of the 4 embedded cylinders is determined according to the actual situation of the part to be processed, but the number of the embedded cylinders is required to be consistent with that of the holes on the daughter board, namely, one ends of the embedded cylinders are inserted into the round holes on the motherboard 1 and are fixedly connected. The other end of the embedded cylinder is in sliding fit with the daughter board, an elastic annular key is arranged in an annular groove in the middle of the embedded cylinder, and the embedded cylinder is provided with a pneumatic telescopic elastic annular key, has the functions of quick positioning, limiting and locking with the daughter board, and achieves the purpose of quickly replacing the clamp. The standard machine tool workbench is provided with T-shaped grooves, and the mother board and the workbench are connected and fixed by the T-shaped grooves.

4 quantity of design confirm the round hole according to the actual conditions of waiting to process the part below the daughter board 2, and the round hole internal periphery is provided with the annular groove, and the annular groove is used for fixed connection elasticity annular key.

As shown in fig. 4. The embedded annular positioning interface is provided with a positioning ring groove matched with the elastic annular structure on the embedded cylinder of the motherboard and used for positioning and limiting the daughter board. And the daughter board is provided with tools such as a limiting support, a pressing plate and the like according to the size and the shape specification of the workpiece, and the tools are used for fixing the part.

The working process is as follows: the parts are fixed on the daughter boards in advance and are placed outside the machine tool, the mother board is fixed on a workbench of the machine tool, before the parts are machined, the daughter boards with the parts are quickly placed on the mother board by manpower or a robot and are connected by a quick-change universal interface, the machining is started, the parts can be continuously fixed on the daughter boards for standby in the machining process, after the first parts are machined, the machine tool is stopped, the parts on the daughter boards on the workbench are quickly taken down by the manpower or the robot, then the parts on the other daughter boards are quickly placed on the mother board, the next parts are machined, the parts can be clamped on the daughter boards during the machining process, the machined parts can also be taken down from the daughter boards, and therefore, when the parts are replaced by using a traditional special clamp, a large amount of time is saved.

If parts of different types are machined, the efficiency improving result is more obvious, when the special fixture is used, if the parts need to be replaced, the special fixture needs to be taken down from the fixture table firstly, then another special fixture is placed, finally the parts are clamped and machined, and if the fixture disclosed by the utility model is used, the time for machining different parts is consistent with the time for machining the parts of the same type.

Another advantage of utilizing this frock is: the link of newly finding the original point of the coordinate system is avoided, which is brought by the traditional special fixture replacement, and the working efficiency is further improved. Before a data machine tool processes a part, an original point of a processing coordinate system needs to be found in a trial processing mode, after a special fixture is replaced in a traditional mode, the position of the fixture under the machine tool coordinate system is changed, and the original point of the processing coordinate system needs to be found in a trial processing mode again. The position of the mother board on the machine tool is unchanged all the time, and the daughter board only needs to be replaced when the parts are replaced, so that the time for finding the original point of the coordinate system again when the same parts are processed is saved, and the processing efficiency is improved.

The key point of the utility model is that the fixture is divided into a daughter board and a mother board, so as to respectively realize the functions of fixing with a workbench and fixing with parts, and the mother board is connected with the daughter board through a universal quick-change interface, so that the problem of low equipment utilization rate in multi-variety and small-batch production is solved, and the problem that the automation technology is difficult to popularize and apply in the production of multi-variety and small-batch products is solved.
