Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0014] a kind of like figure 1 The shown end-tooth flange fork slotting positioning device includes an expanding mandrel 3 corresponding to the ear hole of the end-tooth flange fork 1 to be processed, and the expanding mandrel 3 is connected to a taper handle that matches the taper hole of the machine tool 5, a through hole is provided on the central axis of the taper shank 5 and the expansion mandrel 3, and there are several axially arranged slits 31 at the free end of the expansion mandrel 3. A pull rod 6 runs through the hole, and one end of the pull rod 6 is connected with a tapered pull head 2 matching the tapered inner hole at the end of the expansion mandrel 3, and a cylinder rod is arranged at the other end of the pull rod 6. A cylinder 9 that is relatively rotatable with the pull rod 6 .

Abstract

The invention discloses a positioning device for grooving of an end tooth flange fork. The positioning device comprises an expansion mandril corresponding to a lug hole of the end tooth flange fork to be machined; the expansion mandril is connected onto a conical handle matched with a conical hole of a lathe; a through hole is formed in a central shaft of the conical handle and the expansion mandril; the free end part of the expansion mandril is provided with a plurality of axially arranged seam ports; a pull rod penetrates through the through hole; one end of the pull rod is connected with a conical puller matched with a conical inner hole in the end part of the expansion mandril; the other end of the pull rod is provided with a cylinder rod and a cylinder capable of rotating relative to the pull rod. The conical shape on the puller is matched with the conical inner hole in the expansion mandril, so the free end part of the expansion mandril is tensioned on the lug hole in the end tooth flange fork to be machined to achieve the aim of axially positioning the end tooth flange fork to be machined, so the symmetry and concentricity during secondary clamping of the product are improved, the clamping error brought by the secondary clamping is reduced, and the product grooving precision is improved.

Description

technical field [0001] The invention relates to a machining and positioning tool for end-tooth flange forks, in particular to a groove-cutting and positioning device for end-tooth flange forks. Background technique [0002] During the processing of the end-tooth flange fork, it is necessary to perform grooving operations on the two lug holes. Because it is necessary to cut grooves on both lug holes of the end-tooth flange fork, it is necessary to perform secondary clamping for changing the surface of the product during processing. However, when the existing clamping and positioning device is in use, the symmetry and concentricity of the two clampings cannot be guaranteed, and it is easy to cause clamping errors, thereby affecting the quality of the grooving. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention aims to provide a positioning device for notching and positioning the end tooth flange fork, which ...
