Abstract
The utility model relates to a drill-positioning device for a woodworking processing machine tool, and in particular relates to a drill-positioning fixture for a precise wooden bead. The drill-positioning fixture comprises a main shaft connecting rod and is characterized in that a conical ER chuck is embedded in the front end of the main shaft connecting rod, a tool sleeve of which the front end is provided with a tool hole is fixed in a central hole of the ER chuck, an inner wall of the tool hole is formed by a parallel surface opposite to the front end of the tool sleeve and an arc inner wall of the ER chuck, and a locking nut is sleeved outside the front end of the main shaft connecting rod. Therefore, the fixture provided by the utility model is reasonable in design, practical and convenient.
Description
(1) technical field
The utility model relates to wood working machinery drilling-hole positioning device, particularly the wooden pearl Location Clamping Tool for Drilling Hole of a kind of precision.
(2) background technology
At present, in many processing Mu Zhu factory, the chuck of its process tool is all to use from the side very easily the broach shell of screw fastening, because drilling tool self structure is the restriction of cuboid, the drill bit of center cutter not only cannot find center accurately, and often adds the dynamics of holding and cause not loosening, even fractures, so not only reduce working (machining) efficiency, increased a lot of unpredictable processing costs and percent defective simultaneously.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of reasonable in design, and structure is accurate wooden pearl Location Clamping Tool for Drilling Hole easily.
The utility model is achieved by the following technical solution:
A wooden pearl Location Clamping Tool for Drilling Hole, comprises main shaft connecting rod, it is characterized in that: described main shaft connecting rod front end is embedded with cone shape ER chuck; Described ER center of collet is fixed with the cutter sleeve that front end is cutter holes in hole, and the parallel surface that cutter sleeve front end is relative and ER chuck arc inner wall form the inwall of cutter holes; Described main shaft connecting rod front end outer cover has the locking nut that steps up ER chuck.
Described ER chuck front end protrudes from main shaft connecting rod, and ER chuck projection outer wall is the closing in shape taper shape that diameter diminishes; The endoporus of described locking nut is shoulder hole, comprises the San Jie hole that the first hole, rank, increase and the ER chuck conformability shaft section of the tapered shape that matches with ER chuck projection are the second-order hole of dentation, match with main shaft connecting rod; The cross section of described cutter holes is cyclic quadrilateral.
In order to remain on rotary course cuboid cutter drill bit in process Zhong center, described main shaft connecting rod shank and the concentricity of cutter sleeve drill bit are not more than 0.05MM, in order to make full use of the circumference clamping force of cutter sleeve and even clamping force radially, described cutter sleeve circumferencial direction in process evenly continues stressed, not only evenly push two square cutter hubs and clamp middle drill bit, guaranteed that drill bit is in processing rotary course Zhong center simultaneously.
In order better to guarantee stability and the accurate location degree of cutter in process, described main shaft connecting rod and cutter sleeve are all processed through accurate grinding.
The beneficial effects of the utility model are: the precision wood pearl Location Clamping Tool for Drilling Hole of this utility model is simple in structure, novel in design, not only can locate accurately but also clamping force is evenly stablized, reducing to greatest extent cutter surprisingly fractures, clamp convenient and swift simultaneously, be conducive to enhance productivity, before and after cutter holes itself, all open groove 360 degree circumference uniform distributions, can realize cutter radially with circumferencial direction uniform stressed, better guarantee the stability of drill bit in process, reduce the generation of the unexpected situation that fractures, be suitable for wide popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is axial cross section structural representation of the present utility model;
Accompanying drawing 2 is right view of the present utility model;
In figure, 1 main shaft connecting rod, 2 ER chucks, 3 cutter holes, 4 cutter sleeves, 5 locking nuts.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises main shaft connecting rod 1, it is characterized in that: described main shaft connecting rod 1 front end is embedded with cone shape ER chuck 2; In described ER chuck 2 centre bores, be fixed with the cutter sleeve 4 that front end is cutter holes 3, the parallel surface that cutter sleeve 4 front ends are relative and ER chuck 2 arc inner walls form the inwall of cutter holes 3; Described main shaft connecting rod 1 front end outer cover has the locking nut 5 that steps up ER chuck 2; Described ER chuck 2 front ends protrude from main shaft connecting rod 1, and ER chuck 2 projection outer walls are the closing in shape taper shape that diameter diminishes; The endoporus of described locking nut 5 is shoulder hole, comprises the San Jie hole that the first hole, rank, increase and the ER chuck 2 conformability shaft sections of the tapered shape that matches with ER chuck 2 projections are the second-order hole of dentation, match with main shaft connecting rod 1; The cross section of described cutter holes 3 is cyclic quadrilateral.
Adopt the wooden pearl Location Clamping Tool for Drilling Hole of precision of the present utility model, fixture has a main shaft connecting rod 1, on main shaft connecting rod 1, passes through locking nut 5 as shown in the figure, locking ER chuck 2, by ER chuck 2 clamp-on tool covers 4, the endoporus of cutter sleeve 4 is rectangular, and the wooden pearl process tool of a pair of cuboid is just fixed on cutter sleeve 4 centers, in use procedure, by main shaft connecting rod 1, drive locking nut 5 and ER chuck 2 to rotate, by ER chuck 2 clamp-on tools, overlap 4 clamp-on tools.Adjust the center of drill bit, owing to evenly slotting in ER chuck 2 front and back, can keep cutter sleeve 4 constantly evenly to continue in a circumferential direction stressed.Drill bit is remaining that in process center is constant, can guarantee that the center of wooden pearl boring is not departed from.
