Abstract
The utility model provides a lathe tool drill sleeve, the structure is the cavity sleeve, and sleeve diameter is unanimous with the handle of a knife external diameter of loading sword, the sleeve outer wall mills along the axis direction has four planes, two relative mutual parallels in plane, open two holding screw holes that are used for compressing tightly the cutter arbor respectively on sleeve front end two adjacent planes. The utility model discloses can use on simple and easy numerical control lathe to increased application range, protected the lathe tool simultaneously, increased the technology rigidity of lathe tool, improved the resistance to shock, make the lathe tool clamping, change very convenient.
Description
Technical field
The present invention relates to a kind of versatility device installed on lathe saddle used by internal lathe-tool, it is possible to be arranged on knife rest by lathe tool, and cutter can be protected, improve vibration resistance, make turning process steady.
Background technology
Existing lathe tool drill holder is as it is shown in figure 1, it is configured as cylindrical structural, and there is a positioning step front end, and middle cylindrical is milled with a groove for screw in compression knife bar, and hole size Φ D is in the same size with institute's dress knife bar.Lathe tool drill holder, as the transition piece of knife rest Yu lathe tool, only serves transitional function.Owing to being cylinder, therefore existing lathe tool drill holder cannot be used on the squaring head of simple cnc lathe, it is only used for slant rail numerical control lathe machine tool turret, but simple numerically controlled lathe is very universal, numerical control inner hole lathe tool using owing to not have an available drill holder and very inconvenient thereon, can only adopt the method that direct clamping clamp, be so inconvenience clamping, lathe tool has again injury, and the resistance to shock of lathe tool is also very poor.
Find by retrieving, close patent has CN201220628489 and CN201210314989, the core concept of previous patent is with the gap key that disappears, the cutter being contained in bevel lock cutter elasticity drill holder to be compressed, this drill holder still cannot be used for the squaring head on simple cnc lathe, and the drill holder described in later patent is the device used by machine tool of cutter rotates for workpiece is static milling machine, boring machine.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of lathe tool drill holder, can use on simple cnc lathe, thus adding use scope, protecting lathe tool simultaneously, increasing the technique rigidity of lathe tool, improves resistance to shock, makes lathe tool clamping, changes extremely convenient.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lathe tool drill holder, structure is hollow sleeve, and sleeve diameter is consistent with the handle of a knife external diameter of institute's entrucking cutter；Sleeve outer wall is milled with four planes in the axial direction, and two relative planes are parallel to each other；Two planes that barrel forward end is adjacent have two set screw hole for compressing knife bar.
The endoporus of described sleeve is stepped hole, and leading portion internal diameter is more than back segment internal diameter, and leading portion is for installing the broach shell of institute's entrucking cutter.
Described sleeve adopts 45# steel to make.
The invention has the beneficial effects as follows:
(1) use scope wide, can not only use on numerically controlled lathe turret as former lathe tool drill holder, it is also possible to use on simple cnc lathe squaring head.
(2) protection lathe tool; increase lathe tool resistance to shock; using this lathe tool drill holder to add the lifting surface area of lathe tool knife bar, the not direct clamping of lathe tool, on knife rest, is not directly pressed by knife rest screw; protect cutter; easily broken by knife rest screw because endoporus knife bar slender material matter is hard and crisp, use this drill holder to be equivalent to increase the cross-sectional area of former lathe tool knife bar simultaneously, increase lathe tool vibration resistance; make turning steady, improve turning quality.
(3) use, easy to maintenance, during use, lathe tool knife bar dress is overhang out Len req, compresses the holding screw of drill holder, then this drill holder is loaded knife rest, adjust centre-height, compress knife rest screw, after use, come loose screw, taking-up lathe tool.
(4) material is easy to get, cheap for manufacturing cost, and this lathe tool drill holder adopts No. 45 steel to form through turning, milling, tapping, and middle interspersed modifier treatment, holding screw uses standard M8 screw, and productivity ratio is high, and production cost is low.

In figure, 1-lathe tool, 2-drill holder, 3-holding screw, 4-knife rest, 5-knife rest screw, 6-head cap.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described, and the present invention includes but are not limited to following embodiment.
The structure that lathe tool drill holder is installed and used on simple cnc lathe squaring head, as in figure 2 it is shown, lathe tool 1 is loaded in drill holder 2, is compressed by holding screw 3, drill holder cylindrical is milled with plane, contact for face with knife rest 4, therefore knife rest can be adjacent to, with on knife rest equipped with screw 5 compress drill holder.
In actual use, change with model change owing to lathe spindle center is high, 4～6mm hassock sheet adjustment nose height can be added between lathe tool drill holder with knife rest bottom surface and make itself and alignment of shafts height keep consistent.
Fig. 3 is lathe tool drill holder structure chart, generally a sleeve, is milled with four symmetrical planes, is tapped with four set screw hole for compressing knife bar in barrel forward end, and excircle dimension is as it can be seen, the consistent size of hole size and institute's dress knife bar, and machining accuracy is h8.Its hole size is Φ D, its size is consistent with filled internal lathe-tool shank diameter, outside dimension is Φ d (for Φ 40H8 in Fig. 3), length is L (for 120mm in Fig. 3), surrounding processing has four planes to ensure, and thickness and height dimension are b millimeter (for 36mm in Fig. 3), front end processing has the screw hole of the standard holding screw loading M8, there are four, two, top, two, side, the part that front end is prominent as shown in the figure is exactly installed four holding screws, front end processing has x millimeter (for 2mm in Fig. 3) deep, the step that y millimeter (being 35mm in Fig. 3) is long, man-hour is added for macropore part, broach shell can go deep in workpiece, knife bar cantilevered length can be reduced, further improve vibration resistance.
This lathe tool drill holder adopts 45# steel through turning, milling, tapping, and the modifier treatment that interts therebetween can machine, and material is easy to get, production process is simple, only lathe tool need to being loaded broach shell during use, the facet stretched out on Len req screw alignment lathe tool tightens screw, easy to use.
