[ detailed description ] embodiments

Example (b):

referring to fig. 1 to 8, the present embodiment is an exchange type dual stage mechanism 100 of a laser cutting machine, which includes a lifting support 1, a lifting driving mechanism 2 for driving the lifting support 1 to move up and down, a first stage 3 and a second stage 4 horizontally sliding on the lifting support 1 and vertically stacked, and a horizontal transfer driving mechanism (not shown) for driving the first stage 3 and the second stage 4 to move horizontally.

In order to ensure the lifting stability and the lifting synchronization of the first working platform 2 and the second working platform 4, in this embodiment, the lifting driving mechanism 2 is provided with four groups of front and rear end positions respectively arranged at two sides of the lifting support 1, each group of lifting driving mechanism 2 comprises a base bottom plate 12, a connecting plate 13 fixedly connected with the lifting support 1, a first hydraulic oil cylinder 14 and a second hydraulic oil cylinder 15, one ends of which are hinged on the base bottom plate 12, and the other ends of which are hinged on the connecting plate 13, a guide supporting seat 16 fixed on the base bottom plate 12 and positioned between the first hydraulic oil cylinder 14 and the second hydraulic oil cylinder 15, a vertical guide rod 18 fixed on the guide supporting seat 16, and a guide sleeve 17 fixed on the connecting plate 13 and sleeved on the vertical guide rod 18. Through setting up uide bushing 17 and vertical guide arm 18 for first workstation 3 is more steady with second workstation 4 lift, and plays certain guard action to hydraulic cylinder. A sensor (not marked in the figure) for monitoring the lifting stroke of the lifting bracket 1 is arranged on the guide supporting seat 16.

The lifting bracket 1 is mainly used for carrying two working tables 13 and 14 which need to be exchanged. In the embodiment, the eight hydraulic oil cylinders are adopted to synchronously lift and control the lifting support 1 to move up and down, so that the lifting of a working table surface is exchanged, the horizontal transfer driving mechanism is reused to exchange the working table surface in the working process of the cutting machine, four of the eight hydraulic oil cylinders are mainly used for controlling the lifting of the lifting support 1, and four of the eight hydraulic oil cylinders are correspondingly matched with the eight hydraulic oil cylinders and mainly used for guaranteeing the synchronism of the lifting of four corner areas, so that the lifting stability and the synchronism of the working table surface are greatly improved, the phenomenon that the working table surface is blocked when the horizontal transfer driving mechanism is pulled out is effectively avoided, and the service life and the working efficiency of the mechanism are prolonged.

The bottom of the lifting support 1 is a bottom supporting mechanism formed by welding square pipe profiles, and C-shaped steel profiles are arranged on two side edges of the bottom supporting mechanism and used for horizontally transferring and improving the support of the working table.

In order to further ensure the smoothness of horizontal transfer of the work table, in this embodiment, the lifting bracket 1 includes two parallel support trusses 5 which are arranged oppositely, each support truss 5 includes a first plane 6 and a second plane 7 which is located above the first plane 6, guide rails 8 are respectively arranged on the first plane 6 and the second plane 7 to form two pairs of slide rail mechanisms, the first work table 3 and the second work table 4 include support profiles 9 which slide on the slide rail mechanisms and work support table surfaces 10 which are erected on the support profiles 9, and work table wheels 11 which slide in cooperation with the slide rail mechanisms are arranged in inner cavities of the support profiles 9. One of them guide rail 8 is the hexagonal guide rail in the slide rail mechanism, and another guide rail 8 is the square guide rail, and this embodiment only fixes the hexagonal guide rail in one side, and as the direction of change table translation, the depth of parallelism that appears when can avoiding both sides all adorn the hexagonal guide rail does not reach standard effectively and causes the dead phenomenon of card that appears when the workstation seesaw appears, and machining precision and assembly accuracy require all to reduce simultaneously to the cost has been practiced thrift. The workbench wheels 11 sliding in cooperation with the hexagonal guide rail and the square guide rail are eccentric wheels, and after the first workbench 3 and the second workbench 4 are placed on the guide rail 8, the height of the workbench wheels 11 can be adjusted, so that all the workbench wheels 11 are attached to the guide rail, individual suspension state is avoided, and the running stability of the workbench surface is ensured in the exchange process.

The present embodiment further includes a first stopper mechanism 19 for stopping the position of the first table 3 and a second stopper mechanism 20 for stopping the position of the second table 4. First stop gear 19 and second stop gear 20 are all including setting up at first workstation 3 or 4 terminal and inside first screens piece 22 of seting up first vertical recess 21 of seting up of second workstation, fix at the terminal first lift cylinder 23 of lifting support 1, receive first lift cylinder 23 drive to insert first inserted bar 24 in first vertical recess 21, first vertical recess 21 has the stop part on the workstation horizontal translation year direction. When the first workbench 3 or the second workbench 4 needs to be fixed, the first lifting cylinder 23 drives the first insertion rod 24 to ascend and be inserted into the first vertical groove 21 of the first clamping block 22, so that the degree of freedom of the workbench in the horizontal transfer direction can be limited, the first workbench 3 or the second workbench 4 is prevented from moving, and the position locking effect is achieved.

The front ends of the first workbench 3 and the second workbench 4 are respectively provided with a second clamping block 25, the second clamping block 25 is provided with a second vertical groove 26, and the second vertical groove 26 is provided with a blocking part in the horizontal loading direction of the workbench.
