Description

Inner circle cutting machine

Technical field

The utility model relates to a kind of cutting machine, relates in particular to a kind of device that cuts hard and brittle crystal materials.

Background technology:As everyone knows, inner circle cutting machine is the common equipment of hard and brittle crystal materials such as cutting processing monocrystalline silicon, pottery, glass, sapphire; Present inner circle cutting machine usually by frame, be located at main shaft assembly on this frame, be fixed on workbench on this frame, be located at the traverse feed assembly that can do transverse movement on this workbench and be located at the feeding assembly that can move up and down on this traverse feed assembly and constitute.There is following defective in this traditional inner circle cutting machine:

1) because the Workpiece clamping head that is fixed on the feeding assembly is fixed, only utilize main shaft to drive the cutter ring and rotate workpiece is cut, so cut lengths have received the restriction of interior circular knife physical dimension, cut lengths are less.For example internal diameter is that φ 235mm, external diameter are that the maximum cut lengths of standard insert of φ 690mm are 165mm.

2) because the Workpiece clamping head of clamping bar is fixed; Only utilizing main shaft drive cutter ring to rotate cuts workpiece; Therefore bar is the circular arc line contact with contacting of interior circular knife; And the length of this circular arc line in haveing suffered cutting process, appear by short elongated, again by the long cyclically-varying that shortens, thereby cause cutting force also appear change from small to big, cyclically-varying from large to small again; Circular knife weares and teares fast even damages in finally causing.

3) owing to cutting force in haveing suffered cutting process is a variate; Therefore if the cutting force that rigidly connects when touching with interior circular knife and bar is that benchmark is confirmed a higher cutting speed, then can because of increasing gradually, cutting force damage blade owing to being cut to the bar core; Otherwise if the cutting force when being cut to the bar core with interior circular knife is that benchmark is confirmed a lower cutting speed, though blade can not damage, cutting efficiency then can decline to a great extent.

Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aims to provide that a kind of processing dimension scope is big, cutting efficiency is high, the inner circle cutting machine of blade long service life.

To achieve these goals, the utility model adopts following technical scheme: it comprises frame, be located at main shaft assembly on this frame, be fixed on workbench on this frame, be located at traverse feed assembly on this workbench, be located at the feeding assembly on this traverse feed assembly; Said main shaft assembly is by being fixed on main shaft on the frame, being fixed on cutter ring on this main shaft, driving first motor that this main shaft rotates and constitute; Said workbench constitutes by being fixed on the frame and across the portal frame above the cutter ring; Said traverse feed assembly is made second motor of transverse movement and is constituted by being located at cross slide on this portal frame, being fixed on the portal frame and driving cross slide through first leading screw; Said feeding assembly by be fixed on the cross slide upright to track base, be located at this upright on the track base upright to slide, be fixed on upright on the track base and through second leading screw drive this upright the 4th motor that moves up and down to slide, be fixed on upright on slide axle sleeve, be located at rotating shaft in this axle sleeve, be fixed on this rotating shaft lower end Workpiece clamping head, be fixed on upright on slide and drive the 3rd motor that rotating shaft rotates through traditional mechanism and constitute; Said feeding assembly is provided with the manipulator assembly, this manipulator assembly by be fixed on upright to the track base on the slide, be located at slide carriage on this track base, be fixed on the track base and through the 3rd leading screw drive the 5th motor that this slide carriage moves up and down, be fixed on the slide carriage and extend downward the Workpiece clamping head below mechanical arm, be fixed on this mechanical arm and and constitute with the coaxial bearing of rotating shaft.

Cross slide is provided with balance weight mechanism, and this balance weight mechanism is by being fixed on pulley yoke on the cross slide, being fixed on two fixed pulleys, an end on this pulley yoke and being fixed with the balancing weight other end and walking around said two fixed pulleys and constitute with the upright rope that is connected to slide; Upright lower end to track base is supported by the auxiliary guide rail on the fixing portal frame.

Compare with prior art, therefore the utility model has the following advantages owing to adopted technique scheme:

1) changed original cantilevered workbench into the portal frame structure, therefore strengthened workbench rigidity, improved the machining accuracy of complete machine;

2) owing on the feeding assembly, increased rotating shaft, so Workpiece clamping head can drive bar rotation through this rotating shaft, thereby bar is always a contact (contact point is the point of contact of two round inscribes) with contacting of interior circular knife in whole cutting process; Thoroughly having avoided traditional cutting mode bar and contacting of interior circular knife is the circular arc line contact of length variations; Blade is stressed more even; Overcome the defective of blade easy abrasion or damage under the effect of periodicity alternation cutting force effectively, prolonged the service life of cutter.

3) since in whole cutting process bar and interior circular knife be always and contact, so can select a reasonable and higher cutting speed, increased substantially working (machining) efficiency.

4) since in whole cutting process bar also to rotate, therefore the processing dimension of workpiece can expand and is twice under the constant situation of interior circular knife specification.
