Description

Precision fixing angle shaped material cutter

The utility model relates to a kind of Profile cut-off machine, and particularly precision is decided the angle Profile cut-off machine.

At present, Profile cut-off machine angle positioning device commonly used generally adopts center hole, top location, center hole is located on the plane below the chassis, top being riveted on the steel spring plate, steel spring plate and rolling disc link into an integrated entity with securing member, when the location, need rotate rolling disc, make the top center hole that enters on the chassis, the two coincide and locatees, because top little with the center hole contact area, the elastic force of steel spring plate is limited, so it is poor that contact-making surface coincide, positioning accuracy is low, and steel spring plate is yielding, and losing to have positioning accuracy; This machine does not have lubricating and cooling system simultaneously, uses the dry type patterning method, and time one farm labourer's part machined surface fineness is low, and burr is big, influences machining accuracy, and saw blade is short service life, and maintenance cost is higher.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of orientation angle precision height commonly used is provided, long-term use is indeformable, positioning accuracy is constant, and the workpiece machined surface is highly polished, and the precision of saw blade long service life is decided the angle Profile cut-off machine.

The purpose of this utility model can reach by following measure: it comprises that chassis, rolling disc, locking device, angle scale, pointer, clamping device, cutter sweep, dust gathering arrester, angle positioning device commonly used, electronic spray makeup put this machine, 0 ° of the angle commonly used of angle positioning device commonly used, ± 45 ° of setting circle taper holes are located at the outside of chassis, rolling disc seam, and conical bore is provided with circular cone Xiao who matches with it; Electronic spray makeup is put by atomizer, steel wire rope; rocking arm; water tank; woven hose; rising frame; battery case is formed; atomizer is provided with atomizing disk; waterproof support; dc motor; end plate; power line; the rising frame that electronic spray makeup is put is fixed on the fuselage with securing member; rising frame top is fixed with battery case with securing member; the top is fixed with water tank with securing member; rocking arm; rocking arm and steel wire rope are fixed with securing member; steel wire rope links to each other with wire fixture by the pulley that is located at fixed blade guard one side; wire fixture is fixed on the bearing with securing member; water tank is provided with air admission hole; water tank has woven hose; the other end of woven hose links to each other with atomizer; the termination of woven hose is an atomizing disk is evenly distributed with groove at the periphery of atomizing disk, and atomizing disk is located at saw blade top and places in the fixed blade guard; atomizing disk endoporus and dc motor main shaft are interference fit; dc motor is loaded in the waterproof support, and support is installed in the outside of fixed blade guard with securing member, and the support rear end face is provided with end plate.

The purpose of this utility model can also reach by following measure: this machine angle orientation conical bore and rolling disc platform are in vertical state; The groove that the periphery of atomizing disk is evenly distributed with is straight trough radially, and its groove number is no less than 50.

The utility model has following advantage compared to existing technology:

1. accurate decide the angle Profile cut-off machine owing to adopt conical bore and circular cone Xiao localization method, taper seat cooperation area is big, so the positioning accuracy height uses indeformablely for a long time, does not lose essence.

2. this machine is changed dry type and is cut into the wet type cutting, puts owing to increased electronic spray makeup, and the lubricated cooling of the cooling fluid sawtooth of atomizing is constantly arranged when cut workpiece, thereby the workpiece machined surface is highly polished, the saw blade long service life, thus the number of times of changing saw blade reduced, saved cost of use.

3. owing to be not to adopt common electric pump lubricating and cooling system, thus simple in structure, easy to manufacture, and cost is also lower.
