Embodiment Construction

[0008] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0009] Such as figure 1 As shown, this embodiment includes a "several"-shaped clamp 2. The "several"-shaped clamp 2 is provided with a through hole in the middle that matches the shaft 1 to be processed, and a backing ring 4 is provided on the through hole. The ring 4 matches the top 6.

[0010] How to use the fixture:

[0011] Fix a "several"-shaped fixture 2 bent from a thick plate on the faceplate of the lathe with bolts 5 and nuts 3. The clip has a hole for clearance fit with the shaft. After the shaft passes through the hole of the fixture, screw on the shaft end Fix a backing ring 4 with a clearance fit. In addition to screwing the shaft 1 to be processed on the "ji"-shaped fixture 2 without rotating, the backing ring 4 keeps it from leaving the fixture after it is placed on the center 6. The shaft needs to be supported by the center frame...

Abstract

The invention discloses a clamp for drilling of a shaft part central eye. The clamp is characterized by comprising an n-shaped clamp body (2), and a through hole matched with a shaft to be machined (1) is formed in the middle of the n-shaped clamp body (2). A gasket ring (4) is arranged on the through hole, and the gasket ring (4) is matched with a top tip (6).

Description

Technical field [0001] The invention relates to a clamp for drilling a center hole of a shaft. Background technique [0002] In industrial production, when the center hole of the shaft is damaged, it is necessary to turn the end face and re-drill the center hole. Because the shaft is a cylindrical workpiece, it is not easy to fix, so it is very cumbersome to process. Summary of the invention [0003] The object of the present invention is to provide a clamp for drilling the center hole of a shaft. [0004] The technical solution adopted by the present invention is: a clamp for drilling the center hole of a shaft, including a "ji"-shaped clamp, and a through hole matching the shaft to be processed is arranged in the middle of the "ji"-shaped clamp. A backing ring is arranged on the through hole, and the backing ring is matched with the center. [0005] The beneficial effects of the invention are: the tool has a simple structure and is convenient to use. Description of the drawings ...
