In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of fire hydrant valve rod shut-off mechanism, comprise workbench, described workbench is provided with the slideway that can slide for workpiece, slideway one end is provided with limited block, thereby also comprises and can be on workbench along guide rail, slide and cut off or away from the cutting machine of workpiece; On described workbench, be also provided with main shaft free to rotate, on described main shaft, be connected with cam, described cutting machine is provided with connecting rod, and described connecting rod one end and cam are suitable; On described workbench, be also provided with and control the return mechanism of cutting machine return and the driving mechanism that drive shaft is rotated.
Described return mechanism comprises guide rod, is fixed on the block on workbench and is fixed on the briquetting on connecting rod, described guide rod one end is fixedly connected with briquetting, the other end also can slide through block on block, and the guide rod between described block and briquetting is partly set with return spring.
Described limited block is provided with level switch.
The utility model has the advantage of, by cam, control cutting machine cutting or return, automatically complete the cutting of workpiece, and cam can realize the continuous cutting of workpiece, the every rotation of cam once, completes once cutting, machines a fire hydrant valve rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fire hydrant valve rod of the utility model shut-off mechanism;
Mark in above-mentioned figure is: 1, workbench, 2, slideway, 3, limited block, 4, cutting machine, 5, cutting edge, 6, main shaft, 7, cam, 8, connecting rod, 9, briquetting, 10, guide rod, 11, block.
The specific embodiment
Fig. 1 is the structural representation of a kind of fire hydrant valve rod of the utility model shut-off mechanism; Comprise workbench 1, workbench 1 is provided with the slideway 2 that can slide for workpiece, and slideway 2 one end are provided with limited block 3, thereby also comprises and can be on workbench 1 along guide rail, slide and cut off or away from the cutting machine 4 of workpiece; On workbench 1, be also provided with main shaft free to rotate 6, workbench 1 is provided with bearing block, and main shaft 6 is arranged on bearing block by bearing, is connected with cam 7 on main shaft 6, and cutting machine 4 is provided with connecting rod 8, and connecting rod 8 one end and cam 7 are suitable; On workbench 1, be also provided with and control the return mechanism of cutting machine 4 returns and the driving mechanism that drive shaft 6 is rotated.By cutting edge 5, cut off workpiece.
Driving mechanism comprises drive motors, and the output shaft of drive motors and main shaft 6 pass through belt transmission.
Return mechanism comprises guide rod 10, is fixed on the block 11 on workbench 1 and is fixed on the briquetting 9 on connecting rod 8, guide rod 10 one end are fixedly connected with briquetting 9, the other end also can slide through block 11 on block 11, and guide rod 10 parts between block 11 and briquetting 9 are set with return spring.
Limited block 3 is provided with level switch.If top is not to level switch for workpiece end, whole system will power-off.Prevent that workpiece end face from not putting in place on top, causes having cut rear workpiece size defective.
Adopt after such structure, by cam 7, control cutting machine 4 cutting or returns, automatically complete the cutting of workpiece, and cam 7 can be realized the continuous cutting of workpiece, the every rotation of cam 7 once, completes once cutting, machine a fire hydrant valve rod, thereby realize automation, save manpower, greatly improve working (machining) efficiency.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
