Abstract
The utility model discloses a drilling bit fixture for a digital controlled lathe, and belongs to the accessories of digital controlled lathes. The drilling bit fixture is characterized by mainly being composed of a clamp body, a conical hole and a limiting neck, wherein the clamp body is a cuboid; the conical hole of which the left end diameter is big and the right end diameter is small is formed in the clamp body; the taper of the conical hole is in line with the taper of a drilling bit taper shank; the axial center line of the conical hole is on the axial center line of the clamp body, or can be located correspondingly above the axial center line of the clamp body; moreover, the inverted-T-shaped limiting neck with a gap in the right side is formed in the right end section of the clamp body at the position corresponding to the right outer side of the small end of the conical hole; the limiting neck can be a vertical through groove or a blind groove with of which the bottom is not penetrated; meanwhile, the limiting neck is communicated with the conical hole, and the longitudinal width of the inner groove of the limiting neck is larger than the diameter of the right end of the conical hole. The drilling bit fixture is easy to use, high in production efficiency and product quality, and low in working intensity of workers.
Description
Technical field
The utility model belongs to the annex of numerically controlled lathe, especially relates to the fixture on a kind of numerically controlled lathe.
Background technology
Numerically controlled lathe carries out hole and adds man-hour, conventionally needs the manual tailstock that drill bit is housed of employing to carry out bore operation, and not only more loaded down with trivial details, consuming time, the consumption power of operation, and product quality is difficult to abundant assurance, has restricted production efficiency.
Summary of the invention
The purpose of this utility model is to propose a kind of numerically controlled lathe drill bit fixture, not only simple in structure, easy to use, and highly versatile, and improve production efficiency and product quality reduces workman's operation intensity.
The purpose of this utility model is achieved like this: drill bit fixture for a kind of numerically controlled lathe (being called for short drill bit fixture), comprise the drill bit with taper shank, it is characterized in that: this numerically controlled lathe uses drill bit fixture mainly by cramping body, taper hole and spacing draw-in groove form, this cramping body is cuboid, and this cramping body can be the cuboid that leading flank or trailing flank are arc surface, on cramping body, offer the large and little axial taper hole of right-hand member diameter of left end diameter, the tapering of this taper hole is consistent with the tapering of drill taper shank, and the longitudinal center line of this taper hole can be positioned on the longitudinal center line of cramping body or the corresponding top that is positioned at the longitudinal center line of cramping body, in addition, in the right-hand member section of cramping body, the spacing draw-in groove of ⊥ shape of right side band gap is offered in the corresponding right outside side that is positioned at taper hole small end, and when the longitudinal center line of taper hole is positioned on the longitudinal center line of cramping body, the groove that this spacing draw-in groove is up/down perforation, and when the longitudinal center line of taper hole is positioned at the top of longitudinal center line of cramping body, this spacing draw-in groove is the blind slot that bottom does not connect, simultaneously, this spacing draw-in groove communicates with taper hole and the sagittal width of the inside groove of this spacing draw-in groove is greater than the diameter of taper hole right-hand member.
During use, only the taper shank of drill bit need to be inserted in the taper hole of this drill bit fixture, then, the cramping body of this drill bit fixture be placed on the knife rest of numerically controlled lathe and clamp, rely on the distortion of spacing draw-in groove to prevent drill slipping, adjusting machined parameters is the automatic drilling of practicable workpiece, and high production efficiency and product quality, reduced workman's operation intensity.
The numerically controlled lathe that the utility model proposes drill bit fixture, not only simple in structure, easy to use, and also highly versatile, improved production efficiency and product quality, reduced workman's operation intensity.
The numerically controlled lathe now in conjunction with the accompanying drawings and embodiments the utility model being proposed is further described by drill bit fixture.
accompanying drawing explanation
Fig. 1 is the schematic perspective view of drill bit fixture for the numerically controlled lathe that proposes of the utility model.
Fig. 2 is the main cutaway view of drill bit fixture for the numerically controlled lathe that proposes of the utility model.
Fig. 3 is the schematic perspective view of the numerically controlled lathe that proposes of the utility model while using by drill bit fixture.
In Fig. 1-Fig. 3: 1, cramping body 2, drill bit 3, taper hole 4, spacing draw-in groove.
The specific embodiment
From Fig. 1-Fig. 3, can find out: drill bit fixture for a kind of numerically controlled lathe (being called for short drill bit fixture), comprise the drill bit 2 with taper shank, it is characterized in that: this numerically controlled lathe uses drill bit fixture mainly by cramping body 1, taper hole 3 and spacing draw-in groove 4 form, this cramping body 1 is cuboid, and this cramping body 1 can be the cuboid that leading flank or trailing flank are arc surface, on cramping body 1, offer the large and little axial taper hole 3 of right-hand member diameter of left end diameter, the tapering of this taper hole 3 is consistent with the tapering of the taper shank of drill bit 2, and the longitudinal center line of this taper hole 3 can be positioned on the longitudinal center line of cramping body 1 or the corresponding top that is positioned at the longitudinal center line of cramping body 1, in addition, in the right-hand member section of cramping body 1, the spacing draw-in groove 4 of ⊥ shape of right side band gap is offered in the corresponding right outside side that is positioned at the small end of taper hole 3, and when the longitudinal center line of taper hole 3 is positioned on the longitudinal center line of cramping body 1, the groove that this spacing draw-in groove 4 is up/down perforation, and when the longitudinal center line of taper hole 3 is positioned at the top of longitudinal center line of cramping body 1, the blind slot that this spacing draw-in groove 4 does not connect for bottom, simultaneously, this spacing draw-in groove 4 communicates with taper hole 3 and the sagittal width of the inside groove of this spacing draw-in groove 4 is greater than the diameter of taper hole 3 right-hand members.
During use, only the taper shank of drill bit 2 need to be inserted in the taper hole 3 of this drill bit fixture, then, the cramping body of this drill bit fixture 1 be placed on the knife rest of numerically controlled lathe and clamp, rely on the distortion of spacing draw-in groove 4 to prevent that drill bit 2 from skidding, adjusting machined parameters is the automatic drilling of practicable workpiece, has improved production efficiency and product quality, has reduced workman's operation intensity.
