Abstract

The utility model discloses a vibration cutting bench drilling machine. The drilling machine is characterized in that the vibration cutting mechanism mainly comprises a main shaft sleeve, a cyclic train, a crankshaft, a connecting rod, and a main shaft; the cyclic train comprises a big angle gear, and a small angle gear; wherein, the big angle gear is mounted in the main shaft box of the box body; the small angle gear is engaged with the big angle gear, mounted on one end of the crankshaft; a flexure bearing is mounted on the main shaft which is positioned in the main shaft sleeve and mounted on the crankshaft through the connecting rod. The utility model has reliable vibration cutting, having no defect that the main shaft and a cam are separated; the rotation speed can be improved, small hole drilling is convenient to be realized, the drilling efficiency is high, and the cutting temperature is low (below 60 DEG C); the vibration cutting bench drilling machine has fine crushing iron dust, smooth dust discharging, good roughness for processing (nearing 1-6), long drilling life time, and uneasy abrasion.

Description

The vibrocutting bench drill

Technical field:

The utility model is a kind of vibrocutting bench drill, and it belongs to the universal machine process equipment.

Background technology:

Known bench drill, as Chinese patent ZL9324350.3, its cutting mechanism mainly is made of cam and main shaft, rotation by cam makes main shaft axial vibration, this cutting mechanism has two shortcomings, and the one, main shaft and cam are thrown off during high-speed cutting, influence the chip breaking chip removal, the 2nd, cam is easy to wear, and the life-span is shorter.Because these two shortcomings cause vibrocutting unreliable, thereby the drilling aperture is difficult, the cutting temperature height, bore the flower frangibility, what the balance of known in addition its feeding of bench drill and casing adopted is hydraulic way, thereby plant maintenance is difficult, easy oil leakage, the amount of feeding can not arbitrarily be controlled.

The utility model content:

The purpose of this utility model is to provide a kind of vibrocutting reliable, and the life-span is longer, and cutting temperature is low, brill is spent the not vibrocutting bench drill of frangibility.

The technical scheme that the utility model is taked is: the vibrocutting bench drill comprises the casing that contains main spindle box and feed box, column, actuating unit, vibrocutting mechanism, feed mechanism, described vibrocutting mechanism is mainly by collar bush, cyclic train, bent axle and connecting rod, main shaft is formed, cyclic train comprises a bevel gear wheel, one bevel pinion, wherein bevel gear wheel is installed in the main spindle box of casing, bevel pinion and bevel gear wheel mesh and are installed in an end of bent axle, bent axle is installed on the collar bush by bearing, and main shaft is arranged in collar bush and is installed on the bent axle by connecting rod.

Simple in structure for making, easy to maintenance, the amount of feeding can arbitrarily be controlled, and feed mechanism mainly is made up of the tooth bar on a gear and the column, and is provided with the spring of balance box in the column.

Because spindle vibration is to drive crankshaft rotating by cyclic train and realize by being connected connecting rod on the main shaft in the vibrocutting of the present utility model mechanism, thereby vibrocutting is reliable, the defect that does not exist main shaft and cam to throw off, rotating speed can improve, and is convenient to realize the aperture drilling, and the utility model bench drill carries out cutting experiment after inventor's trial-production, consequently: cutting temperature low (below 60 ℃), iron filings are in small, broken bits, and chip removal is smooth and easy, and the processing roughness is good (approaching ), brill spends the life-span long, not easy to wear, bradawl is spent also not frangibility, drilling efficiency height, the aperture that drilling 1mm is following smoothly, 0.5mm is above, and to stainless steel, heat-resisting alloy steel, (hardness HRC45 °) hardened steel, also can bore flower and carry out drilling, bore flower with alloy and can also hole glass with common high-carbon steel.These advantages all be common bench drill can't be obtained.

Description of drawings:

Fig. 1 is a main cutaway view of the present utility model.

Fig. 2 is the zoomed-in view of the utility model cutting mechanism.

The specific embodiment:

As can be seen from Figure 1, the utlity model has casing 1, column 2, actuating unit 3, vibrocutting mechanism 4, feed mechanism 5.

Casing 1 contains main spindle box 11, feed box 51.Be provided with spring 22 in the column 2, be used for the weight of balance box 1.Actuating unit 3 contains motor 31, driving wheel 32, driving-belt 33, driven pulley 34, and motor 31 is installed on the casing 1, and driving wheel 32 is connected with motor 31, and driven pulley 34 is connected with collar bush 41, and the driving wheel driven pulley all adopts belt pulley.In conjunction with Fig. 2 as can be seen: vibrocutting mechanism 4 is installed in the main spindle box 11, it mainly is made up of collar bush 41, cyclic train 42, bent axle 43 and connecting rod 44, main shaft 45, cyclic train 42 comprises a bevel gear wheel 46, a bevel pinion 47, wherein bevel gear wheel 46 is installed in the main spindle box 11 of casing 1, bevel pinion 47 and bevel gear wheel 46 mesh and are installed in an end of bent axle 43, bent axle 43 is installed on the collar bush 41 by bearing 48, and main shaft 45 is arranged in collar bush 41 and is installed on the bent axle 43 by connecting rod 44.Feed mechanism 5 mainly is made up of feed gear wheel 52 and tooth bar 53, and tooth bar 53 is located on the column 2, and gear 52 is installed in the feed box 51.

When motor 31 rotated, driven pulley 34 drove collar bush 41 and rotates, and the bent axle 43 that is contained in collar bush 41 dead eyes rotates by connecting rod 44 drive main shafts 45.The bevel pinion 47 of while cyclic train 42, revolve round the sun with bent axle 43 on the one hand, the work that is subjected to bevel gear wheel 46 on the other hand is as rotation, and the rotation of bevel pinion 47 will drive bent axle 43 rotations, the rotation of bent axle 43 drives main shaft 45 again and does axial vibration, thereby realizes vibrocutting.
