Detailed Description

The multi-vehicle type tooling quick switching device of the present invention will be described in more detail with reference to the schematic drawings, in which preferred embodiments of the present invention are shown, it being understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the utility model.

The utility model is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

Referring to fig. 1 to 4, the embodiment of the utility model provides a multi-vehicle-type tooling quick switching device, which comprises an AGV walking frame 1, a motor 3 and a tooling quick-change unit 2, wherein the motor 3 is fixed at the middle part of the AGV walking frame 1, a shaft of the motor 3 is connected with a gear 4 at the bottom of the AGV walking frame 1, the gear 4 is meshed with a rack 5, and the rack 5 is fixed on a supporting frame 6. For example, the support frame 6 may be fixed to the ground.

AGV walking frame 1's relative both ends are equipped with the fixed plate respectively, be equipped with frock quick change unit 2 on the fixed plate, frock quick change unit 2 includes cylinder 21, vertical guiding mechanism 22, connecting plate 23, graduation piece 24, cylinder 21 card is in the mounting hole of fixed plate, two vertical guiding mechanism 22 is located respectively the both sides of cylinder 21, vertical guiding mechanism 22 with adopt L type connecting plate to connect between the fixed plate, cylinder 21's guide arm with the bottom of connecting plate 23 is connected, the top of connecting plate 23 is equipped with U type groove, graduation piece 24 card is in U type inslot or with U type inslot separation.
