Abstract

The utility model relates to a cutting tool for sections, particularly a three-phase section cutter composed of a machine base, a section clamping device, a resetting device, a dynamic force generating and driving device, a cutting device, etc. As a cutting grinding wheel is arranged on one end of a motor, and dynamic force is transferred through an engaging gear, therefore, the three-phase section cutter has the advantages of simple structure, small size and low cost and is an ideal cutting tool for sections.

Description

The three-phase Profile cut-off machine

The utility model relates to the cutting tool of section bar, especially a kind of three-phase Profile cut-off machine of being made up of support, section bar clamping device, resetting means, power generation and transmission device, cutter sweep etc.

Existing three-phase Profile cut-off machine, its structure is by support, the section bar clamping device, supporting base, link, motor, abrasive cut-off wheel, reduction torsion spring, compositions such as operating grip, its medium section clamping device and supporting base are installed on the support, link is connected with supporting base through bearing pin, reduction torsion spring is installed on the bearing pin, motor and abrasive cut-off wheel are installed in the two ends of link respectively, and at link the abrasive cut-off wheel end is installed operating grip is housed, adopt belt transmission between motor and the abrasive cut-off wheel, the Profile cut-off machine of this belt driven type has complex structure, the cost height, shortcomings such as volume is big.

The purpose of this utility model provides a kind of simple in structure, cost is low, volume is little three-phase Profile cut-off machine with regard to being to overcome the deficiencies in the prior art.

For achieving the above object, the utility model is by support, section bar clamping device, operating grip, supporting base, bearing pin and be installed in reduction torsion spring on the bearing pin etc. and form, it is characterized in that: supporting base is hinged through an end of bearing pin and single-arm shift bracket, the other end of single-arm shift bracket is installed with motor, and the output shaft of motor links through meshing gear and abrasive cut-off wheel axle.

For achieving the above object, the utility model can also reach by following measure: be provided with check chain between single-arm shift bracket and support.

The utility model is owing to be installed in an end of motor with abrasive cut-off wheel, and through the meshing gear transferring power, so have advantage simple in structure, that volume is little, cost is low.

Description of drawings:

Fig. 1 is that master of the present utility model analyses and observe;

Fig. 2 is the A-A zoomed-in view of Fig. 1;

Mark among the figure: support 1, handle 2, handwheel 3, screw mandrel 4, screw mandrel frame 5, clamping plate 6, supporting base 7, bearing pin 8, reduction torsion spring 9, single-arm shift bracket 10, check chain 11, motor 12, output shaft 13, meshing gear 14, abrasive cut-off wheel axle 15, abrasive cut-off wheel 16, protective cover 17, operating grip 18, switch 19.

Accompanying drawing is a kind of structural representation of the present utility model, also is the schematic diagram of a kind of embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described: as shown in Figure 1 and Figure 2, support 1, the section bar clamping device of being made up of handle 2, handwheel 3, screw mandrel 4, screw mandrel frame 5, clamping plate 6 are same as the prior art, and this does not give unnecessary details.Supporting base 7 usefulness bolts are installed on the support 1, be hinged through the end of bearing pin 8 with single-arm shift bracket 10, the other end of single-arm shift bracket 10 is installed with motor 12, the output shaft 13 of motor 12 links through meshing gear 14 and abrasive cut-off wheel axle 15, the output of abrasive cut-off wheel axle 15 is installed with abrasive cut-off wheel 16 through nut, abrasive cut-off wheel 16 is covered with protective cover 17, in order to realize automatically reseting of abrasive cut-off wheel 16, reduction torsion spring 9 is installed on bearing pin 8, between single-arm shift bracket 10 and support 1, is provided with check chain 11.During use, section bar is placed in the clamping device clamps, press switch 19, actuating motor 12, output shaft 13 rotations of motor drive abrasive cut-off wheel axle 15, abrasive cut-off wheel 16 rotations through meshing gear 14, and push handle 18 makes the abrasive cut-off wheel of rotation cut section bar.After work was finished, unclamp operation handle 18, single-arm shift bracket 10 drove motor 12 under the effect of reduction torsion spring 9, abrasive cut-off wheel 16 automatically resets.
