Abstract
The utility model discloses a boring head with a guide device, which mainly consists of a joint, a rear knife and the guide device, wherein the joint is used for being connected with a boring bar, the rear knife with a boring tool is mounted at the front end of the joint, and the guide device is mounted on the middle rear portion of the knife and is a group of balls peripherally arranged along the knife. The boring head is low in cost, long in service life and low in adverse impact to quality of processed holes.
Description
Technical field
The utility model relates to a kind of boring head that has guider, to improve the processing characteristics of boring head in the deep hole machining.
Background technology
The employed boring head of deep hole machining technology cooperates a bigger boring bar of draw ratio to carry out boring processing usually, forms a cantilever beam, is easy to generate bigger mismachining tolerance.In order to reduce mismachining tolerance, to guider be set on boring head usually, make on its hole wall that is directed at completion of processing, and form a fulcrum.Mostly but known guider is the alloy guide frame, and the hole wall in this alloy guide frame and the hole of completion of processing forms sliding friction pair, wearing and tearing easily, the machining accuracy in especially this effect of attrition hole.In case this class guider damages in addition, change also cumbersomely, cause working (machining) efficiency low.In addition, known guider can not be adjusted bad adaptability in boring head size radially.
Summary of the invention
For this reason, the utility model lost efficacy easily at present boring head guider, and influenced the defective of institute's machining hole quality, provided a kind of cost low, and long service life, to the little boring head that has guider of institute's machining hole quality negative effect.
The technical solution adopted in the utility model is:
The utility model has the boring head of guider, mainly is made up of the joint that is used to connect boring bar, the guider that is installed in the back cutter hub that has boring cutter of this joint front end and is installed on the cutter hub postmedian, described guider be one group of ball along the circumferential setting of cutter hub.
The boring head that has guider according to technical solutions of the utility model adopts ball to substitute existing alloy guide frame, and the change sliding friction is rolling friction, and the speed that guider lost efficacy is slow, has prolonged the service life of guider greatly.Than the alloy guider, ball is much lower to the requirement of material, and assembly structure also wants much simple, low cost of manufacture.
Above-mentioned boring head, described ball is arranged on the joint by the retainer that circumferentially evenly is provided with the axle sleeve shape of radial direction through hole, and is provided with the runway of ball in the retainer, and wherein ball partly is stuck in corresponding described radial direction through hole.
Above-mentioned boring head, described runway mainly is made up of symmetrical two parts, forming cross section is the runway of V-type, wherein first is by axial limiting, second portion is assemblied on the cutter hub by dive key, and correspondingly, on cutter hub, also be provided with the adjustment component that is used to adjust described second portion axial location.
Above-mentioned boring head, described adjustment component comprise with first of cutter hub threaded engagement adjusts nut, and this first end face adjusting nut holds on described second portion.
Above-mentioned boring head, the end face that the first adjustment nut holds described second portion is provided with counterbore, and the diameter of this counterbore is matched with the diameter of the part of described raceway greater than described cutter hub.
Above-mentioned boring head, described adjustment component comprise that also being used to lock second of the described first adjustment nut adjusts nut.
Above-mentioned boring head, raceway after, adjustment component is preceding, and described cutter hub is provided with the axle collar that raceway is carried out axial limiting behind raceway.
Description of drawings
Below in conjunction with Figure of description the technical solution of the utility model is further described, wherein:
Fig. 1 is a kind of sectional structure schematic diagram that has the boring head of guider according to technical solutions of the utility model.
Fig. 2 cuts open structural representation for the left side of retainer.
Among the figure: 1, cutter hub, 2, boring cutter, 3, second adjusting nut, 4, first adjusting nut, 5, runway, 6, retainer, 7, ball, 8, dive key, 9, joint.
The specific embodiment
With reference to the boring head that has guider shown in the explanation accompanying drawing 1, mainly is made up of the joint 9 that is used to connect boring bar, the guider that is installed in the back cutter hub 1 that has boring cutter 2 of this joint front end and is installed on the cutter hub postmedian, described guider be one group of ball 7 along the circumferential setting of cutter hub.
Mounting structure about ball 7, because of it is the member that forms rolling friction pair, only limit to provide rolling element just can meet the demands to its mounting structure, therefore, conventional mounting structure just can satisfy the requirement of this programme, preferably, in order to change conveniently, and friction evenly, and described ball is arranged on the joint by the retainer that circumferentially evenly is provided with the axle sleeve shape of radial direction through hole, and be provided with the runway 5 of ball in the retainer, wherein ball partly is stuck in corresponding described radial direction through hole.
In order to increase the adaptability of boring head, described runway mainly is made up of symmetrical two parts, forming cross section is the runway of V-type, wherein first is by axial limiting, second portion is assemblied on the cutter hub by dive key, and correspondingly, on cutter hub, also be provided with the adjustment component that is used to adjust described second portion axial location.Can adjust said adjustment component so as required and act on described second portion, so, the relative motion of second portion and first just drives ball generation motion radially, that is to say that the revolution diameter of ball can and then change, and its applicability is also just along with enhancing.About driver part, it selects just to produce axially-movable, to drive described second portion with reference to its forms of motion, the forms of motion of second portion is fairly simple, also very simple in the realization, but, preferably, described adjustment component comprises with first of cutter hub threaded engagement adjusts nut 4, this first end face adjusting nut holds on described second portion, and the screw thread ratio is easier to locking, is convenient to the location of ball.
Further, for obtaining bigger adjustment nargin, the end face that the first adjustment nut holds described second portion is provided with counterbore, and the diameter of this counterbore is matched with the diameter of the part of described raceway greater than described cutter hub.
Reliable for what guarantee to lock, described adjustment component comprises that also being used to lock second of the described first adjustment nut adjusts nut 3.
A kind of structure of optimization, raceway after, adjustment component is preceding, and described cutter hub is provided with the axle collar that raceway is carried out axial limiting behind raceway, is convenient to adjust and assembling.
