Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 4, the fast positioning device includes two sets of symmetrically disposed positioning mechanisms, each positioning mechanism includes a substrate 1, a lower die 2 and an upper die 3, the lower die 2 is fixed on the substrate 1, and the lower die 2 has a guiding structure for guiding and limiting; the upper die 3 is provided with a limit groove 3a matched with the lower die 2; the upper part of the upper die 3 is provided with a mounting part 3b for fixing a clamp; wherein, when going up mould 3 and installing in guide structure department through spacing groove 3a, guide structure carries out automatic guidance and spacing to last mould 3 position.

The working principle of the invention is as follows: go up mould 3 and be used for mounting fixture, will go up mould 3 and remove to lower mould 2 on, make on the guide structure of lower mould 2 is aimed at to spacing groove 3a on the lower mould 2, will go up mould 3 through guide structure and automatic direction and spacing, make and go up the placing that mould 3 position can both be accurate at every turn, make the anchor clamps that go up mould 3 can keep in same position, cooperate the manipulator of working, make it use same set of programming at every turn, need not readjust, great saving the time.

The upper die 3 is mounted in such a manner that the upper die 3 is vertically placed on the lower die 2, but the position of the limiting groove 3a on the upper die 3 may deviate due to the requirement for a relatively precise alignment limiting structure, but the size cannot be particularly large.

Specifically, the guide structure can be tightly fitted in the stopper groove 3 a. After the guide structure has fully entered the stop groove 3a, its position is not movable.

Specifically, the guide structure comprises at least one first punch 4 and at least one second punch 5, the first punch 4 is fixed on the base plate 1, and the upper part of the first punch 4 is provided with a first guide part 4a with a conical section; the second punch 5 is fixed to the base plate 1, and the second punch 5 has a second guide portion 5a having a tapered cross section at an upper portion thereof. After the first guide part 4a and the second guide part 5a enter the limiting groove 3a, the conical structures can be attached to the inner wall of the limiting groove 3a to slide, and finally the first guide part 4a and the second guide part 5a are completely attached to the inner wall of the limiting groove 3 a.

Specifically, the first punch 4 and the second punch 5 are arranged non-parallel. This design can improve the stability of the upper die 3.

Specifically, the first punch 4 and the second punch 5 are perpendicular to each other. In the vertical state, the stability is optimal.

Specifically, the substrate 1 is provided with a plurality of first positioning holes 1 a. The first positioning hole 1a is used to fix the substrate 1 and does not move substantially every time the upper mold 3 moves.
