Accompanying drawing explanation
Fig. 1 is the structure cross-sectional schematic of the utility model machine cutter head.
Embodiment
Below in conjunction with drawings and Examples, the structural principle of the utility model machine cutter head and specific implementation are described further:
As shown in Figure 1, a machine cutter head, comprises permanent seat 1 and cylindrical shell 2, and the lateral margin of permanent seat 1 lower surface has breach, the upper end of cylindrical shell 2 has bending, and the lower end breach of permanent seat 1 is fixedly connected with the 3rd screw 30 by the second screw 20 with the bending of the upper end of cylindrical shell 2.
Its middle cylinder body 2 is for interior hollow and inside are notch cuttype to form the first container cavity and the second container cavity, and the internal diameter of the first container cavity is greater than the internal diameter of the second container cavity.
In the first container cavity, be sheathed with piston 21, piston 21 is fixedly connected with cutter shaft 3 below, and cutter shaft 3 is axially in the second container cavity, and cutter shaft 3 lower ends are connected with break bar assembly 4, and break bar assembly 4 comprises the break bar 5 that its underpart connects.
Wherein piston 21 can be any in rubber piston, work in copper plug, aluminium piston, cast-iron piston, cast-steel piston, Ceramic piston, is wherein preferably work in copper plug.Piston 21 peripherys are provided with for the storage tank of accommodating elasticity the first sealing-ring 22 (figure does not indicate), and the inner-wall surface of the outside surface of the first sealing-ring 22 and the first container cavity supports Elastic Contact; Piston 21 lower surfaces have corresponding hole (not indicating in figure) with cutter shaft 3 upper surfaces along central shaft, by intert a connection piece (not indicating in figure) in hole, piston 21 is fixedly connected with cutter shaft 3, and wherein web member and hole can be to be threaded connection.
Wherein cutter shaft 3 also partly extends in the first container cavity and is connected with piston 21, makes the inner wall surface of piston 21 and the first container cavity form a cavity 23, and piston 21 is moved up and down in cavity 23.
On permanent seat 1, the position of corresponding piston 21 offers the first pore 24 communicating with the upper surface of piston 21, on cylindrical shell 2, offer and make cavity 23 and extraneous the second pore 25 communicating, air pressure is exerted pressure through 24 pairs of pistons 21 of the first pore, promote piston 21 along the axial downward movement of cavity 23, and then be with movable arbor 3 and break bar assembly 4 to press down, and by the second pore 25 air inlet pressures, piston 21 is resetted.
Further, the periphery of cutter shaft 3 is arranged with wear-resistant sleeve 26 and spring 27 successively from lower end to upper end, and spring 27 supports on the upper surface of wear-resistant sleeve 26.
Wherein the outer surface of the internal surface of wear-resistant sleeve 26 and cutter shaft 3 fits, wear-resistant sleeve 26 outside surfaces are fixedly connected with the inner-wall surface of the second container cavity of cylindrical shell 2, when cutter shaft 3 presses down axial motion, relative wear-resistant sleeve 26 slides, the the second container cavity inner wall abrasion that prevents cylindrical shell 2, has also reduced the wearing and tearing of cutter shaft 3 by wear-resistant sleeve 26; The lower surface of wear-resistant sleeve 26 is concordant with the lower surface of cylindrical shell 2 with cutter shaft 3, and the axial length of wear-resistant sleeve 26 is shorter than the length of the second container cavity, and the upper surface of wear-resistant sleeve 26, lower than the upper surface of the second container cavity, is positioned at the second container cavity inner.Wear-resistant sleeve 26 is preferably tinbronze wear-resistant sleeve, further reduces the wearing and tearing of cutter shaft 3.
Its medi-spring 27 one end support in the upper surface of wear-resistant sleeve 26, and the other end supports on piston 21 lower surfaces.After glass cutting completes, spring 27 equally also can promote piston 21 axially upwards resetting along cavity 23.Therefore, understandably, piston 21 both can be introduced air pressure by the second pore 25 resets piston 21, also can piston 21 be resetted by suppressing of spring 27.
Further, the threaded hole being connected with break bar assembly 4 along being provided with in the radial direction of cutter shaft 3 (in figure do not indicate), inserts an oil-deflecting element 6 in threaded hole, have oil-feed duct 7 in oil-deflecting element 6, and kerosene normally, for lubricating glass cutting head.In addition, this oil-deflecting element 6 can also play and prevent that cutter shaft 3 is in the effect of cylindrical shell 2 interior rotations.
Its principle of work: air pressure is delivered on piston 21 by the first pore 24, piston 21 is exerted pressure, piston 21 is along the axial downward movement of cavity 23, drive cutter shaft 3 to press down, further drive cutter shaft component 4 to press down, the break bar 5 of break bar assembly 4 lower ends contacts with the sheet glass on glass cutting machine table top, when break bar 5 by certain track with constant pressure after on glass rolling across, at the line of cut that stays one on glass, by this line of cut, glass can be broken into two with one's hands, reach the object of glass-cutting.Wherein utilizing air pressure to promote in piston 21 processes, gas in cavity 23 is discharged by the second pore 25, and another effect of having cut rear ventilating pit 25 is to promote piston 21 along the axially upwards reset of cavity 23 for introducing air pressure, also can piston 21 be resetted by spring 27 is set at piston 21 lower surfaces.
By piston 21 is set in cylindrical shell 2, form cylinder seal, abandoned airbag unit in the past, by the repeatedly flexible of air bag, become the piston motion of piston 21 in cylindrical shell 2 with extensional motion, resistance to air loss is better, and the life-span is longer, and component are more general, reduce cutting cost, improved production efficiency.
As shown in Figure 1, the lateral margin of permanent seat 1 lower surface has breach, so the bottom of permanent seat 1 forms a part of protruding (not indicating in figure) and extend in the first container cavity, and the part of this protrusion is provided with the second sealing-ring 28 with the inner wall surface of the first container cavity.
Permanent seat 1 side opening fluted (not indicating in figure), in groove, by the 4th screw 40, be fixedly fitted and connected second dovetail-indent piece 101, in groove, also by the first screw 10, be flexibly connected first dovetail geosynclinal block 102, between the upper surface of first dovetail geosynclinal block 102 and permanent seat 1, part is provided with clearance space 103, the first screw 10 through permanent seat 1 and first dovetail geosynclinal block 102, makes first dovetail geosynclinal block 102 utilize clearance space 103 to swing up and down from the top down.
Wherein first dovetail geosynclinal block 102 and second dovetail geosynclinal block 101 can be arranged on glass cutting machine on other parts away from one end of permanent seat 1 groove, it is dovetail-indent track, and then whole machine cutter head has been arranged on dovetail-indent track, so just a plurality of machine cutter heads can be installed on dovetail-indent track simultaneously, in motion cycle of glass cutting machine, can cut out the sheet glass number identical with machine cutter head quantity is installed, greatly enhance productivity.Only need to unscrew or tighten the first screw 10, first dovetail geosynclinal block 102 is swung up and down, adjust the position of machine cutter head, and then be connected on dovetail-indent track simultaneously, very convenient quick.
All these improvement or conversion should be understood that, for those of ordinary skills, can be improved according to the above description or convert, within all should belong to the protection domain of the utility model claims.
