Abstract
The invention discloses an eccentric sleeve processing tool which is characterized by comprising a rack, wherein a fixing tool is arranged on the rack and comprises a core shaft, a first annular flange and a second annular flange are formed in the outer circumference of the core shaft, the outer circumference of the second flange is larger than that of the first flange, a screw rod is arranged on the core shaft, and a press plate and a nut which are movably connected through threads are arranged at one end of the screw rod; one end surface of the core shaft is a fixed surface, a first eccentric boss, a second eccentric boss and a third eccentric boss are formed in the fixed surface, the other end surface adopts an oval outer boss; and the press plate is strip-shaped, a large U-shaped groove and a small U-shaped groove are formed in two ends of the press plate, and the length of the press plate is larger than the diameter of the cross section of the core shaft. The eccentric sleeve processing tool facilitates the turning process and improves the turning efficiency.
Description
Technical field
The present invention relates to a kind of excentric sleeve processing tool.
Background technology
Excentric sleeve from mould out after, because excentric sleeve does not have symmetrical structure, in Tutrning Process, increased beyond doubt the difficulty of turning process, in the situation that there is no auxiliary mould, on engine lathe, cannot complete processing, this existing structure haves much room for improvement for this reason.
Summary of the invention
The object of the invention is, for a kind of excentric sleeve processing tool is provided, to be convenient to turning process, improve turning efficiency.
For achieving the above object, technical scheme of the present invention is:
Excentric sleeve processing tool, it is characterized in that: comprise frame, in frame, be provided with fixing tool, described fixing tool comprises mandrel, the outer circumferential of described mandrel circularizes the first flange and annular the second flange, described the second flange excircle be greater than the excircle of described the first flange, on described mandrel, be provided with screw rod, in one end of screw rod, be provided with pressing plate and nut that screw thread is flexibly connected; An end face of described mandrel is stationary plane, forms the first eccentric boss, the second eccentric boss and the 3rd eccentric platform on stationary plane, and another end face is outer lug boss, and described outer lug boss is oval; Described pressing plate is bar shaped, and two ends form large U type groove and little U-shaped groove, and the length of described pressing plate is greater than the cross-sectional diameter of described mandrel.
The present invention is done further preferably, and the cross-sectional width of described large U type groove is greater than the width of described little U-shaped groove.
The present invention is done further preferably, and the length of described large U type groove is greater than the length of described little U-shaped groove.
The present invention is done further preferably, and described the first eccentric boss upper surface forms the second eccentric boss, and the upper surface of described the second eccentric boss forms the 3rd eccentric platform.
The present invention compared with prior art, has following beneficial effect:
1, in the present invention, adopt above-mentioned frock, compared with the prior art, the excentric sleeve that processes centre bore and end-face helical bottom outlet can be sleeved in the outer lug boss of mandrel, pressing plate and nut are arranged on to the screw portion of mandrel, by fastening nut, excentric sleeve is pressed on end face of mandrel, the claw of last lathe blocks respectively wherein two eccentric boss, just can process easily two off-centre operation cambered surfaces of excentric sleeve, owing to adopting above-mentioned frock, saved on the one hand the eccentric centering before processing, shortened process time, guaranteed on the other hand eccentric dimensional accuracy, improved the Forming Quality of product, meet the requirement of producing in enormous quantities.
2, in the present invention in order to be applicable to different excentric sleeves, described pressing plate is bar shaped, two ends form large U type groove and little U-shaped groove, the length of described pressing plate is greater than the cross-sectional diameter of described mandrel, is applicable to different mandrels and uses, and has expanded the scope of application.
As from the foregoing, turning process is convenient in the present invention, improves turning efficiency.
In order further to explain technical scheme of the present invention, below by specific embodiment, the present invention will be described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is structural representation of the present invention.

Fig. 4 is structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, the present embodiment discloses a kind of excentric sleeve processing tool, it is characterized in that: comprise frame, in frame, be provided with fixing tool, described fixing tool comprises mandrel 1, and the outer circumferential of described mandrel 1 circularizes the first flange 2 and annular the second flange 3, described the second flange 3 excircle be greater than the excircle of described the first flange 2, on described mandrel 1, be provided with screw rod 4, in one end of screw rod 4, be provided with pressing plate 5 and nut 6 that screw thread is flexibly connected; An end face of described mandrel 1 is stationary plane 7, forms the first eccentric boss 9 of eccentric boss 8, second and the 3rd eccentric platform 10 on stationary plane 7, and another end face is outer lug boss 11, and described outer lug boss 11 is oval; Described pressing plate 5 is bar shaped, and two ends form large U type groove 12 and little U-shaped groove 13, and the length of described pressing plate 5 is greater than the cross-sectional diameter of described mandrel 1.
The present invention is done further preferably, and the cross-sectional width of described large U type groove 12 is greater than the width of described little U-shaped groove 13.
The present invention is done further preferably, and the length of described large U type groove 12 is greater than the length of described little U-shaped groove 13.
The present invention is done further preferably, and described the first eccentric boss 8 upper surfaces form the second eccentric boss 9, and the upper surface of described the second eccentric boss 9 forms the 3rd eccentric platform 10.
The foregoing is only one embodiment of the present of invention, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
