It is located on two bases, also including base guide mechanism, the base guide mechanism includes underframe, fixes in two bases
One motor is installed, the rack-driving that the output shaft of two motors is fixedly installed on underframe respectively with is connected,
Base is driven to move along tooth bar bearing of trend on underframe；Line rail is also equipped with the underframe, the line rail is flat with the tooth bar
Row is arranged, and the base bottom is equiped with the slide block being slidably matched with the line rail.
Further, also including detent mechanism, the detent mechanism includes the alignment pin being installed in underframe and is opened in
The pin-and-hole of base bottom.
Further, the base guide mechanism may include the underframe of multiple splicings.
Further, the underframe is provided with workbench.
Further, the underframe top surface both sides are respectively equipped with the groove for extending along its length, and the tooth bar is installed
In the groove, the flank of tooth of tooth bar is vertical with the top surface of underframe, is equipped with the output shaft of motor and is nibbled with the tooth surface of rack
The gear of conjunction.
Further, it is respectively arranged with two lines rail on the corresponding underframe in the bottom surface of each base.
By above description, the present invention compared with prior art, the invention has the advantages that：
The present invention on the basis of traditional Bridge gantry, by increasing base guide mechanism so that base possesses mobile energy
Power, increases the haul distance of Bridge gantry, improves operating efficiency and machining accuracy.
