Abstract
The utility model relates to a cutter installation structure of the machine tool processing, in particular to a reamer bit installation structure for deep hole processing. The reamer bit installation structure for deep hole processing comprises a reamer bit, a reamer bit sleeve, a connecting sleeve, a pin and a screw, wherein, the reamer bit is fixedly arranged on the reamer bit sleeve which is fixedly connected on the connecting sleeve by the pin, the pin vertically passes through the axes center of the connecting sleeve, and the connecting sleeve is connected on a tool shank of the machine tool. The cutter installation structure is characterized in that the reamer bit sleeve and the connecting sleeve as well as the pin, the connecting sleeve and the reamer bit sleeve are in clearance fit. The cutter installation structure has the beneficial effects that the reamer bit sleeve and the connecting sleeve as well as the pin, the connecting sleeve and the reamer bit sleeve are in clearance fit, the free float of the reamer bit in processing is realized, the free float of the reamer bit is beneficial to the automatic alignment when processing the deep hole and the accuracy of the deep hole processing is provided.
Description
Technical field
The utility model relates to a kind of cutter mounting structure of machine tooling, relates in particular to a kind of reamer mounting structure that is used for deep hole machining.
Background technology
In the prior art, when workpiece is carried out deep hole machining, normally make the lengthening knife bar, on knife bar, adorn blade, deep hole is carried out boring.This method is the most frequently used process that is used for deep hole machining, the not high and less demanding workpiece of cylindricity can adopt to dimension precision requirement, but for aperture size precision height, cylindricity require high workpiece, because the workpiece aperture is dark, aperture size is less, when the rigidity of lengthening knife bar can't be accomplished maximum, " cutter relieving " phenomenon in the process is just inevitable, causes the quality of workpiece processing can not reach the pattern requirement.And because cutting parameter is limited in the processing, work efficiency is lower, will influence working (machining) efficiency.
The utility model content
In order to improve the deficiency that former design exists, improve the quality of deep hole machining, the utility model provides a kind of deep hole machining.
The technical solution adopted in the utility model is: a kind of reamer mounting structure that is used for deep hole machining, comprise reamer, reamer cover, adapter sleeve, pin and screw, described reamer is fixedly mounted on reamer and puts, described reamer cover is fastened on the adapter sleeve by pin, pin is the axis centre by adapter sleeve vertically, described adapter sleeve is connected on the lathe handle of a knife by bolt, between reamer cover and the adapter sleeve, pin is matched in clearance between overlapping with adapter sleeve and reamer.
The beneficial effects of the utility model are: between reamer cover and the adapter sleeve, pin is matched in clearance between overlapping with adapter sleeve and reamer, realize that reamer is adding the free floating in man-hour, automatic capturing when the free floating of reamer helps deep hole processing provides the precision of deep hole machining.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: reamer 1, reamer cover 2, adapter sleeve 3, pin 4, bolt 5, lathe handle of a knife 6
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
As shown in Figure 1, a kind of reamer mounting structure that is used for deep hole machining, comprise reamer 1, reamer cover 2, adapter sleeve 3, pin 4 and bolt 5, reamer is connected and fixed by key and is installed on the reamer cover 3, reamer cover 2 is fastened on the adapter sleeve 3 by pin 5, the vertical axis centre by adapter sleeve 3 of pin 4, adapter sleeve is connected on the lathe handle of a knife 6 by bolt 5, between reamer cover and the adapter sleeve, pin is matched in clearance between overlapping with adapter sleeve and reamer.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help reader understanding's principle of the present invention, should to be understood that protection domain of the present utility model is not limited to such special statement and embodiment.
