Abstract
The utility model discloses a fine adjustment fine boring cutter for a common lathe, which comprises a cutter bar and a fine adjustment slipper. A dovetail groove is formed on the cutter bar, a counter bore is formed in the center of the cutter bar dovetail groove, a steel ball is arranged inside the counter bore, the fine adjustment slipper is arranged inside the dovetail groove, a threaded through hole is formed in the center of the fine adjustment slipper, and a dial with a trapezoidal cross section is arranged above the fine adjustment slipper and is screwed down through a screw until the screw contacts with the steel ball for fixing and positioning. An indexable triangular cutter blade is arranged at the end of the cutter bar and is locked and fixed through a locking screw, and the cross section at one end of the cutter bar is truncated. The usage method comprises installing the indexable triangular cutter blade at the end of the cutter bar and locking and fixing with the locking screw; and installing the fine adjustment slipper inside the dovetail groove of the cutter bar, screwing the screw into the fine adjustment slipper, and screwing down until the screw contacts with the steel ball in the cutter bar counter bore and is butted against the steel ball. During hole finish machining process of the common lathe, the radial dimension of a hole can be adjusted when required, and the screw can be screwed leftwards and rightwards to enable the dovetail groove section of the cutter bar to generate elastic deformation using the different positions of the screw and the inclinations of the fine adjustment slipper and the cutter bar dovetail groove, so as to generate micro dimensional change in the diameter direction, i.e. the radial position of the cutter is adjusted using the principles of spirality and inclined plane. The fine adjustment fine boring cutter can overcome the shortcoming of controlling the radial dimension precision by adjusting the tool carriage.
Description
Technical field:
The utility model relates to the machine tools field, and particularly a kind of engine lathe is with finely tuning fine boring cutter.
Background technology:
Though digital control processing now is deep into each manufacture field, but machine tool still is a large amount of use, mainly finish by adjusting planker to processing dimension in the engine lathe aperture, but planker dial precision is 0.02mm, 0.04mm and three kinds of common specifications of 0.05mm normally, corresponding radially minimum precision is 0.04mm, 0.08mm and 0.1mm, the control of Accuracy of finish is that the experience by the operator decides, though the hole boring cutter of lathe special use is also a lot, but special-purpose auxiliary body is arranged all, its structure more complicated, manufacturing efficient is low, and stability is not good.
Summary of the invention:
The purpose of this utility model just provides a kind of simple and reasonable for structure, and is maintainable good, and the boring cutter radial direction is fine-tuning, and radially inching controlled, the working (machining) efficiency high stability is good, is used for the accurately machined fine setting fine boring cutter in engine lathe hole.
A kind of engine lathe is with finely tuning fine boring cutter, comprise knife bar and fine setting slide block, it is characterized in that: have dovetail groove on the described knife bar, the dovetail groove middle of knife bar has counterbore, in the described counterbore steel ball is housed, the fine setting slide block is housed in the described dovetail groove, tapped through hole is arranged in the middle of the described fine setting slide block, indexable triangular blade is equipped with in described knife bar end, and is locked by lock-screw.Described knife bar one end scabbles, and is convenient to install.Directly over the described fine setting slide block dial is arranged.Described fine setting slide block is the trapezoid cross section, contacts stationary positioned by screw-driving with steel ball in the counterbore.
Description of drawings:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of an embodiment knife bar of the utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
In use, indexable triangular blade 4 is contained in the end of knife bar 1, is locked by lock-screw 3; Fine setting slide block 2 is contained in the dovetail groove of knife bar 1, screw 5 is screwed in the fine setting slide block 2 earlier, be screwed to steel ball 9 in knife bar 1 counterbore 6 always and contact, hold out against steel ball 9.One end of knife bar 1 scabbles 8, is convenient to install.Right boring hole on engine lathe, when needs are adjusted the radial dimension in hole, left rotation and right rotation screw 5, utilize the gradient of diverse location and the fine setting slide block 2 and knife bar 1 dovetail groove of screw 5, make the dovetail groove section of knife bar produce strain, produce diametric microscale dimensions and change, promptly utilize spiral and inclined plane principle to adjust the cutter radial position.In the present embodiment, screw 5 adopts the specification of M4 * 0.5, gradient adopted 1: 2, the number of division of dial 7 has 25 lattice, dial whenever moves lattice like this, cutter radial moves 0.01mm, is equivalent to control radial dimension 0.02mm, can remedy the deficiency of the planker control radial dimension precision of adjusting engine lathe like this.Equally, compare with boring cutter with other lathe, it is simple in structure, and maintenanceability is just relatively good, processes the efficient height, good stability.
