Abstract
The utility model relates to a guide device of a boring cutter, consisting of a positioning ring and a guide sleeve, wherein the positioning ring is arranged on a cutter bar; the positioning ring consists of a ring seat and a rolling body which can roll on the ring seat; the guide sleeve is behind a workpiece; the inner diameter of the guide sleeve is matched with the outer diameter of the positioning ring, and is consistent with the diameter of a hole to be processed of the workpiece. When the cutter bar moves forwards, the positioning ring rolls in the guide sleeve or the hole of the workpiece while moving forwards together with the cutter bar; and as the positioning ring and a positioning inner hole generate rolling friction, the positioning accuracy of the cutter is very high.
Description
Technical field
The utility model relates to the cutting tool in the metal cutting processing.
Background technology
The guider of borer in the metal cutting processing generally adopts all-in-one-piece guide pad location, and positioning accuracy is relatively poor.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thereby develops the guider of the higher borer of a kind of positioning accuracy.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of guider of borer, has knife bar, blade is housed on the knife bar, it is characterized in that: knife bar has pilot sleeve outward, it is consistent that the internal diameter of pilot sleeve and workpiece will be processed the aperture, some external diameters and the corresponding to centring ring of pilot sleeve internal diameter are housed on the described knife bar, and described centring ring is positioned at the blade back.
The technical solution of the utility model can also be further perfect, and as preferably, described centring ring is positioned at the rolling element on the ring support by the ring support that is fixedly mounted on the knife bar, and the support ring of supporting rolling element is formed.
Therefore, the beneficial effects of the utility model are: when beginning owing to bore hole, centring ring is done accurately location to knife bar, when knife bar moves forward, centring ring in pilot sleeve or workpiece hole inner edge rolling limit and knife bar move forward together, because centring ring and location endoporus endoporus are rolling friction, so very high to tool's positioning accuracy.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Among the figure: 1 pilot sleeve, 2 support rings, 3 rolling elements, 4 ring supports, 5 workpiece, 6 knife bars, 7 blades.
Go up the position by figure, Zuo Weiqian is after the right side is.
As shown in the figure, blade 7 and two centring rings are housed on the knife bar 6, centring ring is positioned at blade 7 back, and centring ring is made up of ring support 4, support ring 2, rolling element 3.Ring support 4 is installed on the knife bar 6, and rolling element 3 is housed on the ring support, and the rolling element of present embodiment is a ball-type, and rolling element can roll on ring support, and support ring 2 plays supporting rolling element 3.Pilot sleeve 1 is positioned at workpiece 5 back, and is connected with workpiece, and knife bar 6 is positioned at the pilot sleeve hole, and the internal diameter of pilot sleeve 1 and centring ring external diameter match, and to process the aperture consistent with workpiece 5.
Add man-hour, centring ring can be positioned at pilot sleeve 1 or workpiece 5 holes, generally is to be positioned at pilot sleeve earlier, and workpiece 5 or knife bar 6 rotate, the knife bar reach, and centring ring moves forward together on pilot sleeve 1 inner edge rolling limit and knife bar 6, and knife bar is located.When centring ring was advanced in the hole that workpiece processed, just located knife bar in the hole that has processed with workpiece, until completion of processing.
If necessary, centring ring also can be used as the hole that rolling tools have processed to workpiece and makes rolling and processing.
Claims (2)
1. the guider of a borer, has knife bar (6), blade is housed on the knife bar, it is characterized in that: knife bar has pilot sleeve (1) outward, it is consistent that the internal diameter of pilot sleeve and workpiece will be processed the aperture, some external diameters and the corresponding to centring ring of pilot sleeve internal diameter are housed on the described knife bar (6), and described centring ring is positioned at the blade back.
2. the guider of borer according to claim 1, it is characterized in that: described centring ring is positioned at the rolling element (3) on the ring support by the ring support (4) that is fixedly mounted on the knife bar, and the support ring (2) of supporting rolling element is formed.
