Abstract
The utility model relates to a cutter for processing the inner lateral surface of the through holes of mechanical products, in particular to a converse boring cutter. According to the technical proposal provided by the utility model, the converse boring cutter comprises a cutter rod and a converse cutting blade; the end part of the cutter rod is provided with a connecting rod; the end part of the connecting rod is provided with a bearing part vertically intersected thereof; the cutter rod, the connecting rod and the bearing part are integrated into a whole body; the converse boring cutting blade is arranged on the bearing part; and the section of the connecting rod is oblate. The cutter has the advantages that, when in use, the cutting blade generates little vibration along with the rotation of the cutting rod, so as to ensure the inner lateral surface of the through holes of the processed work piece to have better surface quality; in addition, the replacement of the cutter is relatively simple, thus reducing the auxiliary time of production.
Description
Technical field
The utility model relates to a kind of cutter of processing equipment product parts through hole medial surface, especially a kind of reverse boring cutter.
Background technology
Reverse boring cutter (anti-scraper) is the cutter commonly used of processing equipment product parts through hole medial surface.At present, existing reverse boring cutter mainly is made up of knife bar, common reverse boring cutter sheet, housing screw, and it is circular that the knife bar section structure is generally, and the reverse boring cutter sheet partly is whole high-speed steel tool, and this cutter is fixed on the knife bar by housing screw.The reverse boring cutter sector-meeting in actual process of such reverse boring cutter produces bigger vibration along with the rotation of knife bar, the quality of the workpiece through-hole medial surface that is processed into is reduced, and the blade exchange of this reverse boring cutter is cumbersome, increases to produce non-cutting time.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of blade is better along with the vibrative quality less, the workpiece through-hole medial surface that is processed into of the rotation of knife bar, blade exchange simple, reduce the reverse boring cutter of producing non-cutting time.
The technical scheme that provides according to the utility model, described reverse boring cutter comprises knife bar and reverse boring cutter sheet, be provided with connecting rod in the knife bar end, be provided with perpendicular crossing support in the end of connecting rod, described knife bar, connecting rod are integral formula with support and are connected, the reverse boring cutter sheet is installed on the support, and it is oblate that the section of described connecting rod is.
The section of connecting rod is blade shaped, and the section configuration of described blade shaped is two sections shapes that outwards outstanding arc is formed by connecting, and plane and reverse boring cutter sheet that the line of blade root and blade tip forms are vertical setting.
The utility model has the advantages that: in use, the vibration that blade produces along with the rotation of knife bar is less, makes the through hole medial surface of the workpiece after shaping that surface quality preferably be arranged; In addition, the replacing of blade is fairly simple, thereby has reduced the non-cutting time of producing.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the cross-section structure of connecting rod in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: it comprises knife bar 1 and reverse boring cutter sheet 2, be provided with connecting rod 3 in knife bar 1 end, be provided with perpendicular crossing support 4 in the end of connecting rod 3, described knife bar 1, connecting rod 3 are integral formula with support 4 and are connected, reverse boring cutter sheet 2 is installed on the support 4, and the section of described connecting rod 4 is oblate (perhaps oval).The section of connecting rod 3 is blade shaped, and the section configuration of described blade shaped is two sections shapes that outwards outstanding arc is formed by connecting, and plane and reverse boring cutter sheet 2 that the line of blade root and blade tip forms are vertical setting.
The utility model has improved connecting rod 3 (knife bar leading portion) the partial cross section shape of traditional reverse boring cutter, become circular into oblate, under the situation of processing comparable size, can make whole knife bar 1 part rigidity increase by 36%, intensity also improves simultaneously, vibration cutting obviously reduces in the process, has improved the surface quality of part.The support 4 and the knife bar 1 of blade fuse, and it is convenient to make reverse boring cutter sheet 2 change, and reduces and produces non-cutting time.
