Abstract
The utility model relates to a band saw machine with an automatic centering and clamping mechanism. The utility model has the structure that a clamping mechanism of the existing band saw machine is changed into a structure that a clamping jaw of the clamping mechanism of the existing band saw machine is respectively driven by a screw sleeve and a screw rod which are coaxially arranged to quickly adjust the open-close degree and the position of the jaw; the jaw is pushed by a hydraulic piston then to realize the purpose that a work piece is stably clamped. The utility model has the advantages of simple structure, easy manufacture and fabrication and convenient operation and use; the cost of a machine tool can be effectively reduced, the labor productivity can be improved, and the service life of the band saw can be extended; the utility model can be matched with the band saw machines having various types.
Description
The utility model relates to Metal Cutting lathe field, and referring in particular to is a kind of band sawing machine of tool automatic centering clamp mechanism.
The clamp mechanism of band sawing machine is to be used for firm clamping to be cut 2 on the metal a kind of mechanisms for sawing.Traditional band sawing machine clamp mechanism, have two jaws, one is fixed on the working plate, another is by the promotion of hydraulic jack, realization is to the clamping of workpiece, and the clamp mechanism of this structure exists following weak point: can not keep being had the initiative on the line of the cutting between saw wheel and the driven saw wheel by the sawing workpieces center, cause saw blade enter by the unit twist angle of sawing material with leave by the unit twist angle of sawing material undesirablely, easily make saw blade premature wear subscription rate; Jaw is unidirectional in addition moves, and the stroke of hydraulic jack is long, and work efficiency is low, has reduced labor productivity.
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, processing and manufacturing is easy, easy for operation, can keep the band sawing machine of the tool automatic centering clamp mechanism that overlapped with ideal cut line between two saw wheels by sawing workpieces automatically.
The utility model is to adopt following proposal to realize: it is to change existing band sawing machine clamp mechanism into its clamping claw to be driven respectively by coaxial mounted silk braid and screw mandrel, with the folding degree and the position of rapid adjustment jaw, push the purpose that jaw is realized firm holding workpiece by hydraulic piston then.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is an automatic centering clamp mechanism structural representation in the utility model.
See accompanying drawing 1,2, the utility model is by lathe bed 20, electric notes 21, hydraulic system 22, bands for band strainer 23, driven saw wheel 24, column agency 25, active saw wheel 26, bands for band guiding mechanism 27, cooling system 28, automatic centering clamp mechanism 30 is formed, described lathe bed 20, electrical system 21, hydraulic system 22, bands for band strainer 23, driven saw wheel 24, column agency 25, active saw wheel 26, bands for band guiding mechanism 27, the structure of cooling system 28 and installation form are all just the same with prior art, its improvement is that automatic centering clamp mechanism 30 by screw mandrel cover 1, clamps handwheel 3, moving jaw 5, piston 7, cylinder cap 8, slide block 9, oil cylinder 10, regular jaw 14, nut slider 15, screw mandrel 16, setscrew nut 17, workbench 18 is formed, described workbench 18 is packed on the lathe bed 1, and screw mandrel 16 1 ends are provided with screw thread and are installed in an end of workbench 18 by setscrew nut 17, and the other end is a polished rod, be set with one on it and be provided with externally threaded silk braid 1, clamp handwheel 3 and be sleeved on an end of silk braid 1 and follow closely 2 spinnings on polished rod by setscrew nut
*In the groove and with screw mandrel 16, silk braid 1, clamp handwheel 3 radial locations, piston 7, cylinder cap 8 oil cylinders 10 are installed as one, be provided with a tapped through hole and spinning at the center of piston 7 on the external screw thread of silk braid 1 other end, utilize oil cylinder 10 be fixed on workbench 18 an end and with screw mandrel 16, silk braid 1 integral body is positioned on the workbench 18, slide block 9 is sleeved on silk braid 1 end and utilizes alignment pin 6 to snap in the annular groove that is provided with on the silk braid 1 end excircle and with silk braid 1 and slide block 9 axial location, moving jaw 5 is installed on the slide block 9 by screw 4, nut slider 15 spinnings are on the external screw thread of screw mandrel 16, and regular jaw 14 is packed on the nut slider 15 by screw 13.
Operation principle of the present utility model is sketched in following: the utility model in use, other parts are the same with the operation principle of existing band sawing machine, only be that clamp mechanism distinguishes to some extent, when the need clamping work pieces, according to the workpiece size size, rotate and clamp handwheel 3, drive silk braid 1, screw mandrel 16 rotations, because of nut 17 locking that is positioned of screw mandrel 16 ends, can't move axially, therefore, spinning nut slider 15 thereon will be forced to move axially along screw mandrel 16, drive the regular jaw 14 that installs thereon and move together; Simultaneously, silk braid 1 is also with clamping handwheel 3 rotations, because of the silk braid 7 outer pistons 7 that are installed with, piston 7 is subjected to the control of oil cylinder 10 can not produce axial displacement, therefore, force silk braid 1 move axially, drive in the keyway of dog screw 2 on screw mandrel 16 and slide, simultaneously along piston 7, promoting slide block 9 moves axially along screw mandrel 16, to realize regular jaw, moving jaw is made the purpose of move toward one another, realizes width between rapid adjustment two jaws, adapts to workpiece size and changes, because two jaw move toward one another are carried out simultaneously, therefore, the center that can guarantee workpiece overlaps with the ideal cut line between the driven saw wheel of saw wheel initiatively, realizes that symmetry cuts; To guarantee that bands for band is entering by the unit twist angle of cut spare when leaving by cut spare rationally, effectively improve the saw blade force-bearing situation, prolong saw blade service life; More owing to be provided with hydraulic jack in the utility model, piston, when the clamping handwheel is adjusted two width of jaw near the workpiece actual size, then pass through oil cylinder, the hydraulic power of piston, it is cold to promote to live, and drives silk braid 1 motion that is loaded on one with the piston spiral shell, and then drive slide block 9 and the moving jaw 5 that is installed on the slide block 9 clamps workpiece, realizing the purpose of firm holding workpiece, and owing to drive silk braids 1, screw mandrel 16 rapid adjustment width of jaw by clamping handwheel 3, make oil cylinder, the impulse stroke of piston shortens greatly, has reduced the cost that oil cylinder is lived and trembled with fear on the one hand, on the other hand, improve the speed of holding workpiece, also promptly improved production efficiency.In addition, because two jaw chucking powers reach 21 on workbench 18 makes short and small workpiece all can have been expanded the scope of application of band sawing machine greatly by firm clamping.
In sum, the utility model is simple in structure, and processing and manufacturing is easy, and is easy for operation, can effectively reduce the cost of lathe, raises labour productivity, and prolongs band saw and is suitable for and the supporting use of the band sawing machine of various models service life.
