Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below so that those skilled in the art can better understand the advantages and features of the present invention, and thus the scope of the present invention will be more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
Examples
A workbench exchange structure of a precise double-station horizontal machining center comprises a pull pin and hook mechanism, a chain wheel transmission mechanism, a workbench supporting plate sliding guide mechanism, a limiting device and a cylinder locking mechanism.
A pin pulling and hook pulling mechanism: the pull pin 1 consists of a shaft 2 and a roller bearing 3, the roller bearing 3 is arranged on the shaft 2, as shown in detail in figure 1, the whole pull pin 1 is fixed with a chain 4, the chain 4 drives the pull pin 1 to move, and the pull pin 1 hooks a drag hook on a workbench 5 to drive the whole workbench to move forwards.
The chain wheel transmission mechanism comprises: the pull pin 1 is arranged at the side part of the chain 4 and is driven by the chain wheel 6 to move; the motor is installed to driving shaft 7 bottom, and driving shaft 7 facial make-up bearing 8 is adorned in the bearing frame inside, and relative rotation, sprocket 6 and driving shaft 7 pass through hexagon socket head cap screw fixed cooperation, and when the motor circular telegram was rotatory, thereby drive driving shaft 7 and rotate and drive sprocket 6 rotatory, drive driven shaft 9 through chain 4 and rotate drive pull pin 1 round trip movement, as figure 3.
