Description

Multipurpose carving machine

Multi-purpose graving apparatus.

The utility model belongs to machine tool field, particularly the miniature lathe of industrial art engraving usefulness.

The existing plant equipment great majority that are used for industrial art engraving usefulness still adopt the motor belt transmission, transmit power on the operating desk.This structure transmission chain length, opereating specification is little, inefficiency, workpiece can not be located, and very dangerous.

The purpose of this utility model is to provide a kind of to industrial art department and cottage industry can bore materials such as bamboo and wood, jade, stone, pottery, plastics, glass, shell and metals, mill, grinding is the multi-purpose graving apparatus of major function.

Multi-purpose graving apparatus described in the utility model is made up of lathe bed, power part and workbench.Power part is fastened on the lathe bed housing (5) with hang, can and move up and down along column (19) 360 ° of widely different commentaries on classics of do, realize the action of advance and retreat cutter, workbench is fixed on the base (1) with screw, table top can be done the vertical and horizontal feed motion, finish various stock removal actions, the time spent can not remove from base.Power part also can use separately, with hand-held workpiece is done free cutting processing.Behind attachment device such as tipping flexible axle etc. on the power part, further expanded functionality and opereating specification, realization correct grinding, polishing, texturing, meticulous engraving such as gold stamping.

Be described further below in conjunction with the each several part structure and the operating principle of accompanying drawing multi-purpose graving apparatus:

Lathe bed is made up of base (1), column (19) and lathe bed main body.The lathe bed main body is an assembly, and it comprises the outer pivot point lever of lathe bed housing (5), lock dog (23), back-moving spring (31), tie down screw (18), stop screw (12) and mechanism.Column (19) becomes 90 ° to be press-fitted installation with base (1), is the location benchmark of lathe.The lathe bed main body is sleeved on the column together with lock dog (23), back-moving spring (31) by the axis hole at lathe bed housing (5) two ends.Tie down screw (18) becomes through hole whorl to be connected with lock dog one side, and the two is held out against on column, becomes the load basis of whole lathe bed main body, becomes a fixing outer fulcrum of leverage simultaneously.Leverage is made up of action bars (7), pole socket (26) cover for seat (28) and ship and resell on another market (16), and cover for seat (28) is fixed on the lathe bed housing with screw thread, becomes a force.When pressing action bars (7), lock dog (23) and tie down screw (18) are motionless, and lathe bed housing (5) is then descending at the effect lower edge of lever force column (19) together with power part, compresses spring (31) simultaneously, finish the feed action; When decontroling action bars, withdrawing resets under the effect of spring force.Stop screw (12) is contained on the lathe bed housing (5), and is descending with housing, be the operation bottom dead centre when lock dog (23) is touched in the screw bottom, so the way of available adjustment screw position regulated machine tool travel.

Lathe bed housing (5) is a box parts, and available iron, non-ferrous metal, plastics, bakelite and composite thereof are made.One end has the pincerlike hoop of a rubber-like, also tightens up with knurled nut (20) with this clamping power part.Lower shaft hole becomes movingly with column (19) on the other end, so as to beat before and after the restriction lathe bed main body.

Lock dog (23) is one and has certain thickness shape of a hoof flat blocks, and the one side constitutes spiral with female threaded hole and tie down screw (18) pays, and the two is fixed tightly on column.In order to limit the lathe bed main body for the deflecting of column, the lock dog both sides have projection and lathe bed housing (5) both sides to join work, and so as to guiding with reduce friction.Certainly, the profile of lock dog should also can be other three-dimensional shape with the change of shape of lathe bed housing (5) inner chamber.

Back-moving spring (31) is a common garden cylindrical spring, also can be other flexible member.

Power part is made up of motor and drill chuck.Motor can be to exchange or direct current generator, and rotating speed can adopt single speed, many speed or stepless speed regulation, and switch or arrangements for speed regulation directly are attached on the motor field frame.Change that cutter can bore, mills, grinding.For making power part hand-held convenient when operating separately, can handle be set at certain position of motor.Above-mentioned power part also can be an electric hand drill.

Workbench is a three-decker, and each is with the dovetail groove snapping.Bottom is screwed on base (1), and bottom and middle carriage are paid transmission with spiral, realizes length feed; Middle carriage and table top are realized traverse feed with the lever transmission.Some T-slots are arranged in order to steady job on the table top.Workbench can not pull down from base (1) by the time spent.

In order to enlarge the opereating specification of multi-purpose graving apparatus, realize freely processing and expanded functionality, set up attachment devices such as flexible axle.When flexible axle is installed, must unload drill chuck (2) from power part, with inner cone shaft coupling (36) and motor main shaft (35) socket, the outer ring is fixed on the motor drive end bearing bracket (3) with screw (34) with sleeve bearing (37).For making flexible axle sleeve pipe (40) that the latitude be arranged at work, on sleeve bearing, have oval gathering sill (38), with screw (39) slide-and-guide in groove.The flexible axle other end is operating grip (42), and structure no longer describes in detail.

The utility model contrast prior art has following advantage:

1, multipurpose. By the replacing instrument can realize boring, mill, mill, polishing, the multiple cutting such as gold stamping;

2, can make workpiece reach certain required precision;

3, easy accessibility, working (machining) efficiency height, handling safety;

4, behind the tipping flexible axle, opereating specification is big, can carry out variously freely processing according to different needs.Can realize that comprehensive installation is to adapt to the requirement of different workpieces after unloading lower table.
