Abstract
The utility model relates to a machine tool, in particular to an anti-lock pushing fastening body of a machine tool spindle. The anti-lock pushing fastening body comprises a pushing fastener (1), a coupling shaft (2) and a wear-resisting bushing (3), wherein the circumference of the pushing fastener is provided with a groove, and the circumference of the coupling shaft is provided with a waist type hole; the coupling shaft is internally connected with the pushing fastener, and the groove is corresponding to the waist type hole. Thus, debris detained in the wear-resisting bushing can be thrown out through the groove and the waist type hole, the time for cleaning debris blocking at the spindle due is reduce, the time of the spindle to produce lock is prolonged, the abradability of the wear-resisting bushing is reduced, the service life of the wear-resisting bushing is prolonged, and the working efficiency of the machine tool is increased.
Description
Affiliated technical field
The utility model relates to a kind of lathe, and what be specifically related to is a kind of machine tool chief axis anti-lock tight pushing body.
Background technology
The tight pushing body that present lathe is used for main shaft is to be made of tight pushing device, coupling spindle and wear-resistant sleeve, wherein tight pushing device and coupling spindle all are complete cylindrical form, when material cuts with the main shaft operation, having a little chip is trapped in the wear-resistant sleeve, can't get rid of automatically, increase the wearing and tearing of wear-resistant sleeve and the time that the main shaft place clears up owing to the foreign material obstruction, reduced the service life of wear-resistant sleeve, reduced the operating efficiency of lathe simultaneously.
Summary of the invention
In order to overcome deficiency of the prior art, it is a kind of rational in infrastructure that the utility model provides, and prolongs and prolong the tight pushing body that main shaft produces the time of locking service life.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises tight pushing device, coupling spindle and wear-resistant sleeve, and wherein said tight pushing device is provided with groove on circumference.Described coupling spindle circumference is provided with mounting hole.Be connected in the coupling spindle in the tight pushing device, wherein the set groove of the set mounting hole of coupling spindle and tight pushing device is corresponding.
The utility model is by above-mentioned specific design, compared with prior art, when material cuts with the main shaft operation, the chip that is trapped in the wear-resistant sleeve place can throw out by groove and mounting hole, reduce the main shaft place because foreign material stop up the time of cleaning, prolonged the time of main shaft generation locking, reduced the wear intensity of wear-resistant sleeve, increase the service life of wear-resistant sleeve, improved the operating efficiency of lathe.
Description of drawings
Fig. 1 is a planar structure schematic diagram of the present utility model.
Fig. 2 is the left view of the related tight pushing device of Fig. 1.
Fig. 3 is the structural representation of the related coupling spindle of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model structure is described further:
As shown in Figure 1, the utility model comprises tight pushing device (1), coupling spindle (2) and wear-resistant sleeve (3), and wherein said tight pushing device (1) is provided with groove on circumference.Described coupling spindle (2) is provided with mounting hole on circumference.Be connected in the coupling spindle (2) in the tight pushing device (1), wherein the set groove of the set mounting hole of coupling spindle (2) and tight pushing device (1) is corresponding.Be connected to coupling spindle (2) in the wear-resistant sleeve (3).The chip that is trapped in the wear-resistant sleeve place can throw away by described groove and mounting hole, thereby has prolonged the time that produces the locking state, improves the efficient of lathe, has also increased the service life of wear-resistant sleeve (3) simultaneously.
Claims (3)
1. a lathe anti-lock tight pushing body comprises tight pushing device (1), coupling spindle (2) and wear-resistant sleeve (3).It is characterized in that described tight pushing device (1) is provided with groove on circumference.
2. lathe anti-lock tight pushing body according to claim 1 is characterized in that circumference is provided with mounting hole on the described coupling spindle.
3. lathe anti-lock tight pushing body according to claim 1 is characterized in that, the set groove of mounting hole that described coupling spindle is set and tight pushing device is connected in the tight pushing device in the correspondence one by one.
