Description
Technical field
The invention belongs to machinery manufacturing technology fields, and in particular to small-diameter deep counterbore counterbit in a kind of process chamber.
Background technique
In machine components processing, diameter very little, the deeper counterbore of depth need to be processed on part complicated inner cavity sometimes.It is heavy
The processing in hole generallys use the mode of counterbit, and if for such situation using common counterbit head counterbit, by processed hole
Inside inner cavity, working position can not be accurately positioned, and during counterbit, counterbit head also generates certain deviation, causes institute
Decentraction between the counterbore meeting of counterbit and through-hole not can guarantee the working depth of counterbore especially；If using reverse drawing counterbit, face
Face the problem of can not installing counterbit head in the cavity, therefore there is no at present when small-diameter deep counterbore in process chamber good
Method can only be processed using traditional counterbit head, but this method machining accuracy is not high, inefficiency, high rejection rate.
Summary of the invention
Goal of the invention
In order to solve the above technical problems, being solved the present invention provides small-diameter deep counterbore counterbit in a kind of process chamber
The problem of small-diameter deep counterbore counterbit positioning accuracy is not high in part cavities body, and working depth can not be controlled effectively.
Inventive technique solution
In order to achieve the above-mentioned object of the invention, the present invention uses following technical solutions:
Small-diameter deep counterbore counterbit in a kind of process chamber, including counterbit body, the counterbit body include shank and are located at
The drill bit of shank one end；The shank threads are connected with adjusting sleeve, and the adjusting sleeve outer surface is removably connected with positioning sleeve；Institute
It is coaxial to state shank, drill bit, adjusting sleeve and positioning sleeve.
Preferably, it is removably connected with guide post in chisel edge face, guide post is cylinder, and the guide post and the drill bit are same
Axis, guide post outer diameter are mutually fitted with the location hole drilled out in advance when drilling, and the positioning of counterbit body is guided when for processing, and processing essence can be improved
Degree.
Preferably, the adjusting sleeve outer surface offers slot with the positioning sleeve place of matching, and is provided with steel ball in slot.Work as positioning
When set is mobile relative to adjusting sleeve, steel ball can play lubricating action and make the movement of positioning sleeve more smooth；Connection is played simultaneously to adjust
A whole set of and positioning sleeve effect, will not be detached from adjusting sleeve at once when positioning sleeve surprisingly loosens, prevent from hurting operator.
Preferably, the positioning sleeve front end is three-jaw or four paws structure, in order to process the exclusion of crumble.
Preferably, the shank and drill bit are separate structure, and the two is connected by butt welding.
Preferably, the shank, which is additionally provided with, to adjust the nut of cover locking, to prevent adjusting sleeve position in process
Set variation.
Advantages of the present invention
The present invention has the advantages that
Small-diameter deep counterbore is adjusted by shank with the screw thread in adjusting sleeve with counterbit in a kind of process chamber of the present invention
Positioning sleeve front end controls the depth in processing hole at a distance from chisel edge, and due to positioning sleeve front end using three-jaw or
Four paws structure facilitates the exclusion that crumble is processed in process；It additionally uses guide post and processing hole site is accurately positioned, guide counterbit
Body cutting, the very good solution prior art processes position inaccurate, and in process counterbit body direction of travel is also easy to produce partially
The problem of difference.Small-diameter deep counterbore counterbit positioning accuracy is not high in technical solution of the present invention very good solution part cavities body,
The problem of working depth can not be controlled effectively, and the configuration of the present invention is simple can be changed quickly, and be suitable for small in various part cavities bodies
The counterbit of diameter running-deep-hole.
Detailed description of the invention
Fig. 1 is the main view of small-diameter deep counterbore counterbit in a kind of process chamber of the invention.
In attached drawing: 1- counterbit body, 2- guide post, 3- screw, 4- nut, 5- adjusting sleeve, 6- positioning sleeve, 7- housing screw, 8-
Steel ball.
Specific embodiment
In conjunction with summary of the invention general introduction and attached drawing, the specific embodiment that the present invention will be described in detail.
Small-diameter deep counterbore counterbit in a kind of process chamber, including counterbit body 1, the counterbit body 1 include shank and position
Drill bit in shank one end；The shank is shaft-like, and mid diameter is less than front and tail diameter and has one section of external screw thread, institute
It states and is threaded with adjusting sleeve 5 in the middle part of shank, 5 outer surface of adjusting sleeve is cased with positioning sleeve 6 and is detachably connected, detachably connects
Screw, bolt etc. can be used in the mode of connecing, and housing screw 7 is used in this embodiment；The adjusting sleeve 5 and positioning sleeve 6 are cyclic annular knot
Structure, the shank, drill bit, adjusting sleeve 5 and positioning sleeve 6 are coaxial.
It is removably connected with guide post 2 in chisel edge face, guide post 2 is to drill out in advance when cylinder, outer diameter and drilling
Location hole is mutually fitted.The hole of installation guide post 2,2 one end of guide post and hole tight fit are machined in chisel edge face.It is led to further increase
The tightness that column 2 is installed, can drill in 2 other end of guide post and install the screw 3 coaxial with guide post 2 to compress guide post 2.
5 outer surface of adjusting sleeve offers slot with 6 place of matching of positioning sleeve, and steel ball 8 is provided in slot.Steel ball 8 assembles
It is contacted respectively with adjusting sleeve 5 and positioning sleeve 6 after in slot.
The positioning sleeve front end is three-jaw or four paws structure, in order to process the exclusion of crumble.
The shank and drill bit are separate structure, and the two is connected by butt welding.
The shank is additionally provided with the nut 4 for locking adjusting sleeve 5, and the nut is set to 5 rear portion of adjusting sleeve simultaneously
It is threadedly coupled with shank middle part.Shank end and lathe junction are used to be loaded the structure that the hole of drill bit matches with lathe, just
In disassembly and more bit change.
Installation and process are as follows:
Each component for meeting processing hole technical requirements is selected, guide post 2 is mounted on chisel edge, and compressed with screw 3；So
Positioning sleeve 6 is mounted in adjusting sleeve 5 afterwards, and steel ball 8 is packed into the slot between positioning sleeve 6 and adjusting sleeve 5, uses housing screw
7 are fixed on positioning sleeve 6 in adjusting sleeve；By mounted positioning sleeve 6 and 5 integral installation of adjusting sleeve on counterbit body 1, pass through spiral shell
Line regulates the distance of 1 front end face of 6 front end face of positioning sleeve and counterbit body, which is the depth in hole needed for processing, and uses spiral shell
Mother 4 locks.
When processing, first 1 counterbit body shank is mounted on machine tool chuck, at the same by the part having been fixed on fixture together with
Fixture passes through pressing plate together and screw is fixed on lathe, and before processing starts, 2 guide posts of counterbit, which are inducted into part, need to process hole
Bottom outlet in, it is concentric to guarantee that counterbit and part are processed hole, then the technical parameters such as the amount of feeding, revolving speed when counterbit works are set, adds
Working hour close observation, when being worked into demand depth, counterbit can no longer advance automatically.It completes the process at this time, takes out part and ream
Brill.
