Abstract
The utility model provides a detachable double -end cutter, including fixing a cutting tool and the bottom tool, the upper and lower structure of this cutter is the same tool bit and feed shaft through the clamping device connection, clamping device press from both sides in including centre gripping overcoat and centre gripping, cutter centre gripping overcoat is inside leaves threaded hole along the axial, presss from both sides in the centre gripping to link to each other through screw rod and the inside screw hole of centre gripping overcoat, the centre of centre gripping overcoat be equipped with plastic spring, fix a cutting tool and the bottom tool links together feeding the epaxial detachable of matching draw -in groove separately through setting up. The utility model discloses the during operation, the length of cutter is adjusted according to the size of waiting to process the work piece, elder generation to upper and lower cutter, controls the feed shaft again and cuts, does not need frequent change cutter, has improved production efficiency to the machining precision has been guaranteed.
Description
Technical field
The utility model relates to cutting tool field, specifically a kind of detachable double-ended tool bit.
Background technology
Cutting tool is the instrument for machining in machine-building.The structure of various cutter is all made up of clamping part and working portion.The clamping part of overall structure cutter and working portion are all made on cutter hub; The working portion (cutter tooth or blade) of inserted structure cutter is then installed on cutter hub.
According to the size of workpiece to be processed during cutting, need the bite using different size, then adjust the relative position between cutter and workpiece by mobile feed shaft.Existing cutter, particularly solid tool, cumbersome with changing bite, affect production efficiency, and when workpiece is longer, the wayward cutter of feed shaft, causes machining accuracy to reduce; Existing cutter can not bend, and in addition, existing cutter is all single head, and its operating efficiency is very low.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of scalable, flexible, detachable double-ended tool bit, can adjust the length of cutter, improve production efficiency, and ensure that machining accuracy according to the size of workpiece to be processed.
The detachable double-ended tool bit of one described in the utility model, comprise and fixing a cutting tool and bottom tool, the up-down structure of this cutter is identical, comprise the cutter head and feed shaft that are connected by clamping device, described clamping device comprises clamping overcoat and clamping inner clip, cutter holding jacket internal has screwed hole vertically, and clamping inner clip is connected by the screwed hole of screw rod with clamping jacket internal; The centre of described clamping overcoat is provided with plastics spring; Described fixing a cutting tool is linked together by the dismountable draw-in groove that matches be arranged on respective feed shaft with bottom tool.
Described cutter head is connected with the clamping inner clip of clamping device by connector.
The part that described clamping inner clip stretches out clamping overcoat is no more than 1/3rd of clamping its length, prevents clamping inner clip from stretching out cutter and crosses far away and cause clamping inner clip fixing loosely with clamping overcoat.
The utility model beneficial effect is: this cutter is double-ended tool bit, and this operating efficiency is original 2 times; Operationally, upper and lower cutter according to the size of workpiece to be processed, can first adjust the length of cutter, then controls feed shaft and cut, and does not need to change cutter frequently, improves production efficiency, and ensure that machining accuracy; In addition, this cutter can also bend when work, handled easily.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model structure as shown in Figure 1, a kind of detachable double-ended tool bit, comprise and fixing a cutting tool and bottom tool, the up-down structure of this cutter is identical, comprise the cutter head 1 and feed shaft 4 that are connected by clamping device, described clamping device comprises clamping overcoat 3 and clamping inner clip 4, and cutter holding overcoat 3 inside has screwed hole vertically, and clamping inner clip is connected by the screwed hole of screw rod with clamping overcoat 3 inside; The centre of described clamping overcoat 3 is provided with plastics spring 5; Described fixing a cutting tool is linked together by the dismountable draw-in groove 6 that matches be arranged on respective feed shaft with bottom tool.
The part that described clamping inner clip 2 stretches out clamping overcoat 3 is no more than 1/3rd of clamping overcoat 3 length.
During work, according to the size of workpiece to be processed, first adjust the length of cutter, then control feed shaft and cut, do not need to change cutter frequently, improve production efficiency, and ensure that machining accuracy.
The utility model embody rule approach is a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
