Abstract
The utility model provides a deep hole processing device, including the lathe, set up on the lathe and set up the BT handle of a knife on lathe main shaft, boring bar, the lathe main shaft, lathe main shaft BT handle of a knife passes through the movable joint with the boring bar to be realized being connected, and the lathe main motion is transmitted for the boring bar, and the boring bar is fixed on the position sleeve. The utility model provides a deep hole processing device can realize the boring of deep hole on the large -scale work piece and anti - boring, simple structure, convenient operation.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, particularly relates to a kind of deep hole drilling apparatus.
Background technology
Along with the development of science and technology, there is fast development in machine tooling technology, but during existing machine tooling deep hole, length by machine tool chief axis limits, and cannot complete the processing of deep hole, is subject to the hole size restriction of part to be processed simultaneously, the diameter of self-control boring bar is limited, length is long, in process, cutter relieving phenomenon is serious, easily produces waste product, has been difficult to the anti-boring of deep hole simultaneously.
Chinese patent (application number 200520020768.1) proposes chip removal deep-hole processing unit (plant) in a kind of heavy-duty machinery on boring machine or milling machine, comprise the ram on boring machine or milling machine and main shaft, ram be connected guiding trestle and connect, connect guiding trestle built with awarding oily device, award oily device to be connected with high pressure pumping station, main shaft is connected with shaft coupling, and the other end of shaft coupling is equipped with drilling rod, drilling rod is connected with drill bit, and described shaft coupling inner chamber communicates with chip filtration system.The program, owing to being subject to the restriction of this device profile size, can only process great diameter and long hole, is difficult to realize for the processing in small-diameter ultra-long hole and the anti-boring of deep hole.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of deep hole drilling apparatus, can realize the boring to deep hole on large-scale workpiece and anti-boring, and structure is simple, easy to operate.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of deep hole drilling apparatus, comprise lathe, lathe is arranged on machine tool chief axis, boring bar, machine tool chief axis and arrange BT handle of a knife, described machine tool chief axis BT handle of a knife realizes being connected by movable joint with boring bar, and lathe main motion passes to boring bar, and boring bar is fixed on positioning sleeve.Main shaft BT handle of a knife realizes being connected by movable joint with boring bar, and movable joint link BT handle of a knife and boring bar play " universal joint " connection function, the problem that during solution common boring machine deep hole processing, main shaft is too short;
As further optimization of the present utility model, positioning sleeve is arranged on part to be processed endoporus.
As further optimization of the present utility model, boring bar is installed removable cutterhead, removable cutterhead is arranged on boring bar by locking nut.
As further optimization of the present utility model, Cutting tool installation manner is on removable cutterhead.Boring bar is installed packaged type cutterhead, cutterhead is provided with cutter, cutterhead is fixed on boring bar by lock-screw, solves the installation question of cutter.
Accompanying drawing explanation
Fig. 1 is the structural representation of deep hole drilling apparatus provided by the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Deep hole drilling apparatus as shown in Figure 1, machine tool chief axis BT handle of a knife 1 is connected with boring bar 6 by live-knot connecting device 2,3,4, and positioning sleeve 5,9 is fixed on location on part to be processed and lengthens boring bar, and packaged type cutterhead 7 is fixed by lock-screw and boring bar 6; Cutter 8 is arranged on packaged type cutterhead 7, realizes the processing to part deep-hole.
Above-mentioned deep hole drilling apparatus, during installation, boring bar positioning sleeve 5 and 9 is first installed on inner bore of part, then boring bar 6 is passed positioning sleeve 5, after passing by packaged type cutterhead 7 through on boring bar 6, continue again to extend boring bar 6, by boring bar 6 tail end through positioning sleeve 9, then machine tool chief axis BT handle of a knife 1 is passed through live-knot connecting device 2 and Universal joint connector 4, be connected with boring bar 6 by bolt 3, finally packaged type cutterhead 7 being adjusted to correct position is fixed on boring bar 6, is arranged on packaged type cutterhead 7 by cutter 8.
The course of work describes: when using for the first time, should detect, ensure size tolerance requirements and the Geometrical Tolerance Principle in processed hole to processing unit (plant) trial cut result.Add man-hour, first carry out trial cut, the size of back engagement of the cutting edge is controlled by the distance of carving on cutter and cutterhead, and for different hole depths, adjust by the installation site of cutterhead on boring bar, for anti-bore hole, the installation direction by cutter has come.
Above-described embodiment only for illustration of the utility model, but and is not used in the protection domain limiting claim.Every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
