Abstract
The utility model discloses a combined borer which comprises a boring cutter body (1) with a boring cutter rod (12) and a boring cutter handle (11) thereon, wherein one end of the boring cutter body (1) is fixedly connected with the boring cutter handle (11) connected with a machine tool through a clamping chuck. The borer is characterized in that a coarse cutter bit (5), a beveling tool bit (6), a semi-fine cutter bit (7) and a fine cutter bit (4) are arranged on the boring cutter rod (12); and the fine cutter bit (4) is connected with the boring cutter rod (12) through an adjustable cutter seat (3) in an adjustable manner. The borer provided by the utility model solves the problem that the boring precision is low when a traditional borer is used for boring operation.
Description
Technical field:
The utility model relates to the machining cutter, is specifically related to a kind of Combined type boring spot facing cutter.
Background technology:
Along with the mechanical processing industry development, people more and more pay attention to the precision of machining, accurate mechanical equipment particularly, processing request to precision is particularly paid attention to, machining industry adds man-hour in the hole to parts at present, usually need to adopt the different size cutter head that heavy boring, chamfering, right boring are carried out respectively in the hole, in the bore hole operation process, need constantly to change the cutter of different size, above-mentioned processing operating type not only can affect the operating efficiency of bore hole operation, thereby also can be because of constantly changing the precision that cutter affects bore hole.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of adjustable borer seat, this technical scheme not only effectively solves prior art when carrying out the bore hole operation, the low problem of operating efficiency not only, and when having solved traditional boring cutter and carrying out the bore hole operation, the problem that the bore hole precision is low.
The utility model is achieved through the following technical solutions:
A kind of Combined type boring spot facing cutter, comprise boring cutter body (1), be provided with boring cutter bar (12), boring cutter handle (11) on the boring cutter body (1), one end is fixedly connected with boring cutter handle (11), boring cutter handle (11) is connected with lathe by chucks, it is characterized in that: described boring cutter bar (12) is provided with heavy boring cutter head (5), chamfering cutter head (6), half right boring cutter head (7) and right boring cutter head (4), and right boring cutter head (4) is by adjustable cutter seat (3) and adjustable connection of boring cutter bar (12).
The further Technological improvement plan of the utility model is:
Described adjustable cutter seat (3) comprises cutter head mount pad (31), fixed block (32) and adjusting nut (33), be provided with base of tool installing hole (121) on the boring cutter bar (12), cutter head mount pad (31) is arranged in the base of tool installing hole (121) by fixed block (32), cutter head mount pad (31) is threaded connection with fixed block (32), fixed block (32) top is provided with adjusting nut (33), and adjusting nut (33) is threaded connection with cutter head mount pad (31).
The utility model further Technological improvement plan is:
Described boring cutter bar (12) one ends are fixedly connected with boring cutter handle (11), and the opposite end is fixedly connected with backstay (2), and backstay (2) cooperates with lathe afterbody center thimble.
The utility model compared with prior art has following obvious advantage:
Be provided with simultaneously heavy boring cutter head, chamfering cutter head, half right boring cutter head and right boring cutter head on the boring cutter bar of the present utility model, the right boring cutter head is connected with boring cutter bar by the adjustable cutter seat, in the bore hole operation process, the cutter head at needs replacing different size does not carry out heavy boring, chamfering, right boring, not only saved the time of changing cutter, also improved the precision of bore hole when having improved operating efficiency, this base of tool frame for movement is simple, reasonable, design science is convenient to promote the use of.
