Abstract
The utility model discloses a tooling for cutting end surface teeth of a coupling joint. The tooling comprises a cylinder, a bottom plate and a lifting screw rod, wherein the cylinder is fixed on the bottom plate; the inner hole of the cylinder is provided with a circular conical surface; the lifting screw rod is provided with a lifting part, a screw thread part and a press column; the lifting screw rod can be inserted into the inner hole of the cylinder; and the press column leans against the bottom plate. The tooling is capable of guaranteeing the indexing accuracy of the end surface teeth and the ensuring the center of the end surface teeth to be consistent with the coupling joint in installation reference, and is simple in structure, convenient to use and high in production efficiency.
Description
Technical field
The utility model relates to a kind of cutting of end face tooth and uses frock, is particularly useful for having the cutting processing of the end face tooth of tapering axle.
Background technology
In order to adapt to the railway development trend of passenger traffic high speed, shipping heavy duty; China is newly developed a kind of six large power overloading locomotives; This type locomotive has adopted brand-new drive mechanism, includes a kind of novel overall formula flexible shaft coupling, and this shaft coupling has the end face toothing; This contrate tooth profile shape is complicated, and required precision is high.This shaft coupling end face tooth is carried out cutting add man-hour, need a kind of special tooling, it can guarantee the indexing accuracy of end face tooth with the lathe relative fixed, makes end face tooth center consistent with the reference for installation of shaft coupling again.
Summary of the invention
The purpose of the utility model provides and a kind ofly can guarantee end face tooth indexing accuracy, can make the shaft coupling end face tooth cutting consistent with the shaft coupling reference for installation of end face tooth center use frock again.
In order to achieve the above object, the technical scheme of the utility model is that frock is used in the cutting of a kind of shaft coupling end face tooth; Comprise cylinder, base plate and lifting screw rod; Said cylinder is fixed on the base plate, and the endoporus of cylinder has taper seat, and said lifting screw rod has lifting portion, threaded portion and compression leg; The lifting screw rod can insert the endoporus of cylinder, and compression leg can offset with base plate.
The bottom of said cylinder has several screwed holes, and said base plate has and the corresponding counterbore of the screwed hole of cylinder, and cylinder passes the counterbore of base plate through hexagon socket head cap screw and is screwed in the screwed hole of cylinder and is fixed on the base plate.
Have 4 ~ 8 U type mounting grooves on the periphery of said base plate.
The lifting portion of said lifting screw rod is suspension ring.
After adopting said structure; Base plate in the utility model and lathe relative fixed; Can guarantee end face tooth indexing accuracy, it is consistent that the end face tooth center after the cutting of shaft coupling end face tooth and the tapering axis (reference for installation) of shaft coupling can remain, and as long as for the first time with the utility model after on the lathe centering being installed; Follow-up batch cutting processing does not need the repetition centering, has improved production efficiency.In addition, can workpiece and the utility model dismounting be hung through the lifting screw rod after the process finishing, simple in structure, easy to use.

The specific embodiment
Shown in Fig. 1 ~ 6; Frock is used in a kind of shaft coupling end face tooth cutting of the utility model, comprises cylinder 1, base plate 2 and lifting screw rod 3, and said cylinder 1 is fixed on the base plate 2; The endoporus 1-1 of cylinder 1 has taper seat 1-1-1; Said lifting screw rod 3 has the 3-1 of lifting portion, threaded portion 3-2 and compression leg 3-3, and lifting screw rod 3 can insert the endoporus 1-1 of cylinder 1, and compression leg 3-3 can offset with base plate 2.
Like Fig. 1,2,3,4, shown in 5; The bottom of said cylinder 1 has several screwed holes 1-2; Said base plate 2 has the corresponding counterbore 2-1 with the screwed hole 1-2 of cylinder 1, and cylinder 1 passes the counterbore 2-1 of base plate 2 through hexagon socket head cap screw 4 and is screwed among the screwed hole 1-2 of cylinder 1 and is fixed on the base plate 2.
Like Fig. 1, shown in 4,, have 4 ~ 8 U type mounting groove 2-2 on the periphery of said base plate 2 for the ease of fixing with lathe.
Like Fig. 1, shown in 6, for the ease of lifting, the 3-1 of lifting portion of said lifting screw rod 3 is suspension ring.
Like Fig. 1, shown in 2, a preferably clamping processing and manufacturing of the taper seat 1-1-1 of cylinder 1 and the lower surface 1-3 of cylinder 1, with the axis normal that guarantees shaft coupling 5 in base plate 2.The size of the taper seat 1-1-1 of cylinder 1 is with after installing shaft coupling 5, and shaft coupling 5 also exposes a bit of conical surface 5-1 is advisable, and is used to recheck the installation accuracy of shaft coupling 5.
As shown in Figure 1; Initial workpiece adds man-hour; With hexagon socket head cap screw 4 cylinder 1 is connected fasteningly with base plate 2, fixes through the U type groove 2-2 and the lathe of base plate 2 then, the taper seat 5-1 of shaft coupling 5 and the taper seat 1-1-1 of cylinder 1 are assembled; Behind the taper seat 5-1 centering shaft coupling through the segment shaft coupling 5 that exposes, the end face tooth 5-2 of shaft coupling 5 is carried out cutting processing; After the process finishing,, with whole shaft coupling 5 jack-up, hang away shaft coupling 5 until the compression leg 3-3 that lifts screw rod 3 with the threaded interior hole 5-3 of the threaded portion 3-2 precession shaft coupling 5 that lifts screw rod 3.Process second and in batches the time, do not need repetition centering shaft coupling, the taper seat 5-1 that reviews shaft coupling 5 before only need processing get final product, the production efficiency height.
