Description
The utility model belongs to a kind of integral processing machine tool of blind hole.
Up to now, numerous polishing processing unit (plant)s has appearred, as honing machine, grinder, super tarry matter machine, polishing machine, hydraulic press etc., but the polishing of blind hole processing in the part of making for non-ferrous metal, because this kind toughness of material is big, is easy to stop up grinding tools such as oilstone, so the polishing difficulty of processing is strengthened, at present still do not have a kind of ready-made polishing processing unit (plant), can meet the demands.
The purpose of this utility model is to provide a kind of economical and practical non-ferrous metal part blind hole polishing processing unit (plant).
Operation principle of the present utility model is: the abrasive head that has the leather band is under the drive of motor and drive disk assembly and under the travel switch control, can in the blind hole of workpiece to be machined, make rectilinear motion up and down reciprocatingly, the abrasive flows that is mixed by extremely hard abrasive particle and cutting fluid is introduced into the bottom in the hole of workpiece to be machined by the endoporus of abrasive head, when abrasive head down moves, abrasive flows is risen by the helicla flute of bottom along the abrasive head surface, and squeeze the finished surface of wiping the workpiece endoporus and make its polishing, behind to be processed the finishing, move from the workpiece blind hole on abrasive head is quick and withdraw from.And the abrasive flows that has small non-ferrous metal particle can be overflowed from the upper end and be flow to receptacle, so that abrasive head is not blocked.
Embodiment:
Description of drawings:
Fig. 1 is a non-ferrous metal part blind hole polishing processing unit (plant) structure chart.
Fig. 2 is the structure chart of abrasive head.
Fig. 3 is the structure chart of abrasive flows supply.
Wherein: 1 leading screw, 2 belt wheel nuts, 3 belt wheels, 4 motor, 5 universal joints, 6 abrasive flows supplies, 7 defeated material flexible pipes, 8 abrasive heads, 9 workpiece, 10 outer covers, 11 anchor clamps, 12 abrasive flows returnable, 13 belt wheels, 14 belt wheels, 15 motor, 16 bearing pins, 17 screws, 18 endoporus, 19 leather bands, 20 charging doors, 21 left end caps, 22 metallic cylinder, 23 collapsible capsule bags, 24 scraping wings, 25 right end caps, 26 leading screws, 27 motor.
The utility model is made up of motor, leading screw, universal joint, anchor clamps, it is characterized in that:
Motor (15) links to each other with anchor clamps (11) through belt wheel (14,13); Motor (4) is linked to each other with leading screw (1) with belt wheel nut 2 by belt wheel (3); Leading screw (1) links to each other with abrasive head (8) through universal joint (5), bearing pin (16); Abrasive flows supply (6) is connected with screw (17) on the abrasive head (8) by defeated material flexible pipe (7); The outer cover (10) that the bottom is taken mouth out of is connected in the below of anchor clamps (11); Abrasive flows returnable (12) places the below of outer cover (10) outlet.
Rotatablely moving of motor (4) reaches belt wheel nut (2) by belt wheel (3), and belt wheel nut (2) cooperates with leading screw (1); Belt wheel nut (2) rotation promptly drives leading screw (1) and abrasive head (8) moving linearly.
Above-mentioned abrasive head (8) is cylindrical, the working portion band trapezoidal thread of its outer rim, and there is helicla flute on the thread crest surface, and leather band (19) is inlayed wherein (the leather band outside is higher than thread crest); There is endoporus (18) in cylindrical center, is opened on cylindrical base, and endoporus (18) top communicates with side screw (17), and bearing pin (16) is positioned at abrasive head (8) upper end.
Described abrasive flows supply (6) is made up of collapsible capsule bag (23), leading screw (26), scraping wings (24), left end cap (21), right end cap (26), metallic cylinder (22) and motor (27).Wherein on the left end cap (21) charging aperture (20) is arranged, with threaded hole in the middle of the right end cap (25); Collapsible capsule bag (23) right-hand member is connected with scraping wings (24), and left end is connected with left end cap (21); Metallic cylinder (22) two ends are connected with left end cap (25) with left end cap (21) respectively; Leading screw (26) cooperates with screwed hole on the right end cap (25), and the one end is connected with scraping wings (24), and the other end is connected with the output of motor (27); Scraping wings (24) can relatively move along metallic cylinder (22) inwall.
Abrasive flows is tightened blanking cover after being packed into by the charging aperture (20) on the left end cap (21), and leading screw (26) has fixed screw by motor (27) driven rotary because of in the middle of the right end cap (25), and leading screw (26) promptly drives scraping wings (24) and moves as straight line.When scraping wings (24) when being moved to the left the squeezing mill materials flow inject in the abrasive head (8) through defeated material flexible pipe (7).Change the positive and negative rotating speed of motor, can regulate the abrasive flows output pressure.During the work of this device, actuating motor (15), (4) and (27), workpiece (9) rotates, and abrasive head (8) moves down fast, enters in the hole of workpiece (9), and under two travel switch controls, abrasive head (8) is made rectilinear motion up and down reciprocatingly.Abrasive flows is extruded from abrasive flows supply (6), enter the endoporus (18) of abrasive head (8) through defeated material flexible pipe (7), flow to the bottom of the endoporus of workpiece (9), rise along abrasive head (8) helicla flute again, squeeze the finished surface of wiping workpiece (9) endoporus.The abrasive flows of overflowing from workpiece (9) upper end flows into abrasive flows returnable (12) through outer cover (10).Working time is controlled by timer, and completion of processing is moved on abrasive head (8) is quick, withdraws from from the hole of workpiece (9).
