Description
Technical field
The utility model relates to a kind of numerically controlled lathe tool mounting, is specifically related to a kind of four station numerically controlled lathe Quick replaceable drill bit fixtures.
Background technology
During lathe in machining workpiece, often to run into drilling operating, usually need drill bit to be installed on the tailstock of numerically controlled lathe, holed by operative employee's manual operation tailstock.The method labour intensity is large, and working (machining) efficiency is low, and the precision of drilling depth is difficult to ensure.More existing numerically controlled lathe drill bushings, although to be installed on numerically-controlled slide by programming realization automatic drilling, need more bit change time, all must readjust drill bushing position on knife rest, the function of quick bit change can not be reached.Existing numerically controlled lathe drill bushing is installed on knife rest and only compresses by bolt for tool post, and without positioner, being subject to cutting force effect drill bushing may move when machining hole, affects machining accuracy.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of four station numerically controlled lathe Quick replaceable drill bit fixtures, can reliably install and be positioned on numerically-controlled slide, drill bit be vulnerable to cutting force effect and be moved.
The utility model comprises clamp base, ER collet, chuck nut and holding screw; Described clamp base comprises integrated knife rest contiguous block and drill bit mounting blocks; Described knife rest contiguous block offers two fixture locating holes; The location shaft part of two holding screws is threaded with a knife rest hole of knife rest respectively, and embeds in a fixture locating hole of clamp base respectively; The center of described drill bit mounting blocks offers internal taper hole, and outer wall is processed with external screw thread; Described ER collet embeds in the internal taper hole of clamp base, and described chuck nut is connected with the external screw thread of clamp base, and compresses ER collet; The face, internal taper hole hole of the outer wall compressing fixture pedestal of described ER collet.
The central shaft of described two fixture locating holes all be arranged in parallel with the knife rest hole central shaft of knife rest, and is arranged side by side along the installation side surface direction of parallel knife rest contiguous block.
When described clamp base is arranged on knife rest, the central axis of internal taper hole aligns with the central axis of lathe spindle.
The beneficial effects of the utility model are:
1, ER collet of the present utility model standardization, commercialization, easy exchange, axiality is good, centering precision is high, the quick-replaceable of the parallel shank twist drill of 0.5 ~ 34mm different size diameter can be realized, without the need to again to center tool setting, only to the length of the bit direction and the tool setting of numerical controlled lathe Z direction of principal axis, need greatly reduce and process non-cutting time.
2, clamp base of the present utility model and numerically-controlled slide are reliably located and fastening, avoid because drill thrust effect makes cutter move, can ensure the machining accuracy in hole.
3, the utility model can realize numerical control programming boring, reduces labor intensity, enhances productivity.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1,2,3-1,3-2, shown in 4 and 5, a kind of four station numerically controlled lathe Quick replaceable drill bit fixtures, comprise clamp base 2-3, ER collet 2-1, chuck nut 2-2 and holding screw 3; Clamp base 2-3 comprises integrated knife rest contiguous block and drill bit mounting blocks; Knife rest contiguous block offers two fixture locating hole 2-4; The central shaft of two fixture locating hole 2-4 is all vertically arranged, and is arranged side by side along the installation side surface direction of parallel knife rest contiguous block; The location shaft part 3-1 of two holding screws 3 is threaded with a knife rest hole of knife rest 4 respectively, and embeds in a fixture locating hole 2-4 of clamp base 2-3 respectively; The center of drill bit mounting blocks offers internal taper hole 2-6, and outer wall is processed with external screw thread 2-5; ER collet 2-1 embeds in the internal taper hole 2-6 of clamp base, the grip shank of fluted drill 1 embeds in ER collet 2-1, chuck nut 2-2 is connected with the external screw thread 2-5 of clamp base, make the face, internal taper hole 2-6 hole of the outer wall compressing fixture pedestal 2-3 of ER collet 2-1, inwall compresses the grip shank of fluted drill 1.
When clamp base 2-3 is arranged on knife rest 4, central axis and the lathe spindle center of internal taper hole 2-6 are contour, and this height dimension ensures when clamp for machining pedestal 2-3.
The operation principle of this four stations numerically controlled lathe Quick replaceable drill bit fixture:
When using first, by reliable for fluted drill 1 clamping on the drill bit mounting blocks of clamp base 2-3, the knife rest contiguous block of clamp base 2-3 installs the side that side is adjacent to knife rest 4, two holding screws 3 embed in two fixture locating hole 2-4 of clamp base 2-3 through the knife rest hole of knife rest 4, tighten two holding screws 3 by reliable for clamp base 2-3 clamping on knife rest 4.Add ensured man-hour the internal taper hole 2-6 central axis of clamp base and lathe spindle center contour, now, without the need to additionally adjusting the centre-height of fluted drill 1, numerically controlled lathe X-direction and Z-direction can be carried out programming machining hole to good cutter.
When needing the hole of boring another specification, only need unclamp chuck nut 2-2, changing corresponding fluted drill 1 and ER collet 2-1, again tightening chuck nut 2-2, now only need carry out tool setting to numerically controlled lathe Z-direction, reach the object of Quick replaceable drill bit.
