Abstract
The utility model discloses a prestressed sawing machine for railways, highways and bridges. The prestressed sawing machine comprises a stand, wherein a worktable is arranged on the stand; a bracket is rotationally arranged at one end of the worktable; a guide rail is arranged on the bracket; a tool apron is matched with the guide rail in a sliding way; a saw blade is arranged on the tool apron; a saw port of the saw blade faces downwards; an air cylinder is arranged at the lower part of the bracket; a piston rod of the air cylinder is hinged onto the tool apron; the piston rod stretches to control the tool apron to slide on the guide rail back and forth; a fixed clamping plate is arranged on the worktable; a guide groove is arranged at the part of the worktable, which is positioned at the outer side of the fixed clamping plate; a movable clamping plate matched with the fixed clamping plate is matched in the guide groove in a sliding way; a support frame is arranged at the part of the worktable, which is positioned on the outer side of the movable clamping plate; a threaded sleeve is fixed on the support frame; a screw is screwed in the threaded sleeve; the screw is positioned above the guide groove and is parallel to the guide groove; and the inner end of the screw is fixed on the movable clamping plate. The prestressed sawing machine disclosed by the utility model has the advantages of simple structure, reasonable design, small size and convenience for carrying; and according to the prestressed sawing machine, parts with smaller structures can be processed and the service demand of enterprises is met.
Description
Technical field:
The utility model relates generally to a kind of railway, highway, bridge prestress sawing machine.
Background technology:
Sawing machine is a cutter with saw blade, saw band or saw blade etc., the lathe of sawing round metal material, square stock, pipe material and section bar etc.The machining accuracy of sawing machine is generally all not really high, is used for preparation room more and cuts off section bars such as various bars, pipe material.
Sawing machine in the prior art is to drive the saw blade running by driving wheel and driven pulley, and saw blade fracture direction is by the control of guide rail control frame.Manual or hydraulic jack material folding retaining mechanism are housed on the sawing machine in addition, and the hydraulic operation threshold switch etc.
This shows that the sawing machine of prior art exists volume bigger, the defective of structure more complicated.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of railway, highway, bridge prestress sawing machine to be provided, and it is simple in structure, and is reasonable in design.
The utility model is realized through following technical scheme:
Railway, highway, bridge prestress sawing machine include frame, and frame is provided with workbench; It is characterized in that: said workbench one end is rotatablely equipped with support, and said support is provided with guide rail, is sliding combined with tool rest on the said guide rail; On the said tool rest saw blade is installed, the saw kerf of saw blade is downward; Said support bottom is equipped with cylinder, and the piston rod of cylinder is hinged on the tool rest, and piston rod extension and contraction control tool rest slidably reciprocates on guide rail; Said workbench is provided with strap, and the outside that is positioned at strap on the said workbench is provided with guide groove, is sliding combined with the ambulatory splint that cooperates with strap in the said guide groove; The outside that is positioned at ambulatory splint on the said workbench is provided with bracing frame, is fixed with swivel nut on the bracing frame, is installed with screw rod in the said swivel nut, and said screw rod is positioned at the top of guide groove and in parallel, and screw rod the inner is fixed on the ambulatory splint.
Railway, highway, bridge prestress sawing machine is characterized in that: the outer end fixed cover of said screw rod is equipped with control handwheel.
The utility model is controlled tool rest through stretching of cylinder piston rod and on guide rail, is slidably reciprocated, and then realizes that saw blade cuts the purpose of workpiece.
Rotary screw, through feed screw nut's principle, screw rod promotes ambulatory splint and on guide groove, moves, and makes ambulatory splint constantly near strap, finally realizes the purpose of clamping work pieces.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, and volume is little, is convenient to move, and can handle the less parts of structure, satisfied the user demand of enterprise.
