Description

Cutter work angular adjustment apparatus

Technical field

A kind of cutter work angular adjustment apparatus belongs to the Precision Machining field.

Background technology

In cutting process, lathe, anchor clamps, cutter and workpiece have constituted the manufacturing process system of metal cutting, and various processing phenomenons all will go to investigate in above-mentioned manufacturing process system with the cutting rule.Cutter work angular adjustment apparatus is simultaneously as a kind of cutter special fixture, and it can change the cut effect through adjustment cutter operating angle.Therefore, under the constant situation of cutting data, to obtain more how different cut tests are a kind of scientific methods of studying the cut rule and improving the cut effect through changing the cutter operating angle.

At present, the research institution that precision cutting processing is carried out experimental study day by day increases, and research field constantly enlarges.But exploring experiment the early stage of most of research institutions all is to launch more cut tests through the cutter that designs many group various geometric, and it is higher that this research method not only drops into funds, and inefficiency.Related patent U.S. Patent No. and list of references thereof for cutter work angular adjustment apparatus are not found.

Summary of the invention

In order to overcome the deficiency that the existing cutter chucking device of lathe commonly used can not change cutter operating angle aspect, the present invention provides a kind of cutter work angular adjustment apparatus, this device can be easily and effectively with cutter work angle adjustment to meeting the cut requirement.

Patent of the present invention solves the technical scheme that its technical problem adopted:

The cutter 4 that the handle of a knife end has semicircle cambered surface is connected to through bolt 5 on the side plate of base 1 both sides, and the axis of bolt 5 overlaps with the center of circle line of the circular cambered surface of the handle of a knife end of cutter 4.Respectively there is a convexity at the two ends of base 1 side plate; Attachment screw 7 is connected pressing plate 8 on the base 1; The joint portion of two of two ends convexities and pressing plate 8 has through hole on base 1; One cover is installed by a rhizoid thick stick 2 and two sliding spiral pairs that grip slide 3 is formed between the above-mentioned two through hole, described pressing plate 8 is pressed in described sliding spiral pair on the base 1; Two grip slides 3 are through being threaded on the screw mandrel 2; When leading screw 2 relative bases 1 rotate; Two grip slides 3 in opposite directions or opposing slip; And when the handle of a knife of clamp-on tool 4, drive whole sliding spiral pair automatic centering clamping, simultaneously, be equipped with one on base 1 side plate and be used for the auxiliary holding screw that is fixed cutter 4 handle of a knifes; Attack two sections external screw threads that rotation direction is opposite in leading screw 2 inboard center symmetries; Attack female two grip slides 3 all have one section identical with the terminal radius of curvature of the handle of a knife of cutter 4, in order to cooperate and to clamp the cambered surface of handle of a knife, two grip slides 3 are connected through screw thread pair with two sections inside threads of leading screw 2 respectively; Leading screw 2 passes two convexities at base 1 two ends; The Outboard Sections that is positioned at base 1 has been attacked regular screw threads; Engagement is equipped with in order to behind the handle of a knife of grip slide 3 clamp-on tools 4, the leading screw screw pair lock onto the elastomeric pad 9 and nut 10 of base on the regular screw threads, and the two ends of leading screw 2 have and are used to adjust the through hole of fashionable dress tennis partner handle with rotating threaded shaft 2.

Base 1 biside plate upper end is for indicating the circular arc of angle index, and handle of a knife indicates two center lines facing to two surfaces of base 1 side plate, and circular arc and center line together are used for indicating the toolsmith to make angle.

Protruding identical on the size of said pressing plate 8 and shape and the base 1.

Cutter work angular adjustment apparatus is mounted on the lathe cutter saddle through being threaded.

The present invention is before cut; Rotate to cutter 4 operating angle of experiment processing request earlier; Rotating threaded shaft 2 can drive grip slide 3 and entad moves with the handle of a knife of the cutter 4 that is fixedly clamped synchronously then; Tighten holding screw 6 with the auxiliary handle of a knife that compresses cutter 4, fastening nut 10 is with the whole sliding spiral pair that is locked again; If will adjust the operating angle of cutter 4 during next cut, then reverse rotation nut 10, holding screw 6 and leading screw 2 can unclamp handle of a knife, and after the operating angle of cutter 4 being adjusted to processing request, screwing gets final product again.

The beneficial effect of patent of the present invention is; The terminal cambered surface of the handle of a knife of cutter is identical with grip slide cambered surface radius of curvature; And handle of a knife cambered surface center of circle line is handle of a knife centre of gyration line; It is consistent that the change amount that makes the cutter operating angle and handle of a knife rotational angle remain, and realized reliably reading and adjusting the purpose of cutter operating angle; Sliding spiral pair two grip slides when leading screw rotates move to the heart synchronously; Whole screw pair is axially movable before the nut check of two ends; The ability automatic centering, after the locking, axial restraint is motionless; Guaranteed that sliding spiral pair is stable to clamping, the positioning performance of cutter, made the clamped back of cutter operating angle constant and be in and stablize the cut state; Can be applied to multiple machine tooling, simple in structure, saving experiment fees.

The specific embodiment

Be further described for the present invention below in conjunction with the accompanying drawing and the specific embodiment.

The structure of described adjusting device is consistent with summary of the invention in the present embodiment.

As shown in Figure 2, cutter work angular adjustment apparatus is assembled on the knife rest through being threaded; The sliding spiral pair that is made up of leading screw 2 and grip slide 3 is installed on the base 1 through the axis hole interference fit, installs elastomeric pad 9 and nut 10 at the leading screw two ends, pressing plate 8 is assembled in case the circular runout of sliding stop screw pair through attachment screw 7 and base again; The handle of a knife of cutter 4 is assembled on the base 1 through bolt 5, and holding screw 6 is installed on the base side plate, after grip slide clamps handle of a knife, tightens with the auxiliary handle of a knife that compresses again.

During experimental implementation; The laboratory technician rotates to cutter the operating angle of experiment processing request earlier; Then rotating threaded shaft 2 can drive grip slide 3 entad move synchronously with clamp, fixed cutting tool 4; Tighten holding screw 6 and compress cutter 4 with auxiliary, fastening nut 10 is with the whole sliding spiral pair that is locked again; If the cutter operating angle will change cut the time, but just loosening cutter 4 of reverse rotation nut 10, holding screw 6 and leading screw 2 then, and after the operating angle of cutter being adjusted to processing request, screwing gets final product again.
