Description
Technical Field
The utility model relates to the technical field of cutters, concretely relates to interior cold spiral reamer.
Background
Cold helical reamers are tools used in machining for cutting operations. Now, for reduce cost, generally with the tool bit and the blade separately equipment, when the tool bit damages, only need change the tool bit, reduce cost that can be great. Present tool bit is changed very inconveniently, and the workman need use extra instrument to dismantle the tool bit usually for the change of tool bit becomes very inconvenient, and loaded down with trivial details change can also influence the precision of processing simultaneously.
The above problems are problems that the art needs to solve.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide an interior cold spiral reamer to can change the tool bit conveniently, improve the precision of processing.
In order to solve the technical problem, the utility model provides a scheme is: the utility model provides an interior cold spiral reamer, includes the cutter body, the cutter body bottom is provided with the mounting hole, even interval is provided with stopper and spacing groove on the mounting hole internal face, the cutter body is provided with the tool bit through the mounting hole, the tool bit bottom corresponds the spacing groove is provided with the limiting plate, the limiting plate bottom is provided with the cardboard.
As a further improvement, the mounting hole is provided with female threads on the inner wall surface below the limiting block, the snap-gauge is provided with male threads.
As a further improvement, the mounting hole is provided with a fixing hole at the position of the limiting groove.
As a further improvement, the side wall surface of the limiting block is provided with a chamfer.
As a further improvement, the side wall surface of the cutter head is provided with an auxiliary block.
The utility model has the advantages that:
the utility model has the advantages of reasonable structure, it is simple, the simple operation, move limiting plate on the tool bit along the spacing groove, when the cardboard is located the spacing groove below, clockwise rotate the tool bit and make the cardboard be located the stopper under, and carry out spacing card jail with the stopper, when the tool bit damages and need change, only need anticlockwise rotate the tool bit to make the cardboard put aside from the stopper under, shift out the tool bit from the mounting hole at last and change, thereby can reduce the degree of difficulty of changing the tool bit, improve the convenience of changing the tool bit widely, and then improve the precision of processing.

Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, for the utility model discloses an embodiment, including cutter body 1, cutter body 1 bottom is provided with mounting hole 2, and even interval is provided with stopper 3 and spacing groove 4 on 2 internal faces of mounting hole, and cutter body 1 is provided with tool bit 5 through mounting hole 2, and tool bit 5 bottom corresponds spacing groove 4 and is provided with limiting plate 6, and limiting plate 6 bottom is provided with cardboard 7. Remove limiting plate 6 on tool bit 5 along spacing groove 4, when cardboard 7 is located spacing groove 4 below, clockwise rotation tool bit 5 makes cardboard 7 be located stopper 3 under to carry out spacing card jail with stopper 3, when tool bit 5 damages needs to be changed, only need anticlockwise rotation tool bit 5 make cardboard 7 remove from stopper 3 under, shift out tool bit 5 from mounting hole 2 at last and change.
In this embodiment, in order to improve the fastness of being connected of tool bit 5 and cutter body 1 to be provided with female screw 8 on the internal face that lies in stopper 3 below on mounting hole 2, correspond female screw 8 on the cardboard 7 and be provided with pin thread 9, through the cooperation locking of pin thread 8 and pin thread 9, and then improved the fastness of being connected of tool bit 5 and cutter body 1 widely.
In this embodiment, in order to further improve the fastness of being connected of tool bit 5 and cutter body 1, all be provided with fixed orifices 10 in locating at limiting groove 4 on mounting hole 2, use the bolt to pass fixed orifices 10 and fix limiting plate 6, improve the fastness of being connected of tool bit 5 and cutter body 1.
In this embodiment, in order to make the limiting plate 6 smoothly move in the limiting groove 4, the side wall surfaces of the limiting block 3 are all provided with chamfers 11.
In this embodiment, in order to facilitate the rotation of the cutter head 5, an auxiliary block 12 is provided on a side wall surface of the cutter head 5, and the auxiliary block 12 is sleeved with a sleeve, so as to facilitate the rotation of the cutter head 5.
In actual work, the limiting plate 6 on the tool bit 5 moves along the limiting groove 4, when the clamping plate 7 is positioned below the limiting groove 4, the tool bit 5 is rotated clockwise, so that the female thread 8 and the male thread 9 on the clamping plate 7 are connected and fixed, and finally the limiting plate 6 is fixed by penetrating bolts into the fixing holes 10; when the bit 5 is damaged and needs to be replaced, the bolt is loosened, the bit 5 is rotated counterclockwise, and finally the bit 5 is removed from the mounting hole 2 for replacement.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
