Abstract
The utility model provides an elastic arbor device. The elastic arbor device comprises a square arbor, and an alloy tool bit is mounted at the front end of the square arbor. The elastic arbor device is provided with an elastic arbor body, the square arbor is mounted in the elastic arbor body, a square-hole sleeve is arranged on the outside of the square arbor, and jackscrews are respectively arranged between the square-hole sleeve and the square arbor as well as between the square-hole sleeve and the elastic arbor body. A guide key is arranged on the lower portion of the elastic arbor body, hard rubber is arranged between one end of the guide key and the elastic arbor body, and positioning pins are arranged on the guide key. Since the elastic arbor device can provide a buffer space for the tool bit in the process of turning large-modulus worms, striking frequency and sharpening frequency are decreased, the service life of the tool bit is prolonged and processing efficiency is improved.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of elastic cutter bar device.
Background technology
At present, the cutter of using on the existing lathe all is that alloy cutter head is welded direct to lathe tool side's knife bar, and directly clamping carries out turning processing to the cutter platform then, and the lathe tool of this form is when turning machining large-modulus worm screw, because the very big knife bar of penetration of a cutting tool face produces vibrations, turning worm screw surface smoothness is coarse; Because the vibrations blade of knife bar is easy to forge a knife; When turning, because excircle of workpiece is beated, the degree of depth of turning is not very even, so be easy to knife, influences the quality of product, and production efficiency is low, has increased production cost.
Summary of the invention
The utility model provides a kind of elastic cutter bar device, has solved that turning adds the shortcoming of easily forging a knife man-hour in the background technology.
The technical solution of the utility model is achieved in that a kind of elastic cutter bar device, the side's of comprising knife bar, side's knife bar front end is equipped with alloy cutter head, be provided with the elastic cutter bar body, the side's of being equipped with knife bar in the elastic cutter bar body, square knife bar outside is provided with the square hole broach shell, is respectively equipped with jackscrew between square hole broach shell and square knife bar, square hole broach shell and the elastic cutter bar body, elastic cutter bar body bottom is provided with feather key, is provided with hard rubber between feather key one end and the elastic cutter bar body;
Feather key is provided with alignment pin.
The beneficial effects of the utility model are: the utility model can provide the space of a buffering to cutter head when turning, reduces the number of times of forging a knife, and prevents knife and spring cutter, reduces the sharpening number of times, improves the service life of cutter head, improves working (machining) efficiency.
Description of drawings
Fig. 1 is generalized section of the present utility model.
Part explanation: 1, elastic cutter bar body; 2, square hole broach shell, 3, jackscrew, 4, alloy cutter head, 5, square knife bar, 6, hard rubber, 7, alignment pin, 8, feather key.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of elastic cutter bar device, the side's of comprising knife bar 5, side's knife bar 5 front ends are equipped with alloy cutter head 4, be provided with elastic cutter bar body 1, the side's of being equipped with knife bar 5 in the elastic cutter bar body 1, knife bar 5 outsides, side are provided with square hole broach shell 2, between square hole broach shell 2 and the square knife bar 5, be respectively equipped with jackscrew 3 between square hole broach shell 2 and the elastic cutter bar body 1, elastic cutter bar body 1 bottom is provided with feather key 8, be provided with hard rubber 6 between feather key 8 one ends and the elastic cutter bar body 1, feather key 8 is provided with alignment pin 7.
When cutting force was excessive, square hole broach shell 2 meeting drive side's knife bars 5 and alloy cutter head 4 prolonged feather key 8 together and are bent downwardly, and elastic cutter bar body 1 will be pressed onto the hard rubber 6 that is contained in feather key 8 front ends at this moment, plays the effect of buffering.
