Embodiment Construction

[0012] A support device for the inner hole of a thin-walled revolving body part, comprising: an adjusting nut 2, a spring screw rod 3, a connecting block 4 and an adjusting block 5.

[0013] There are six spring screws 3, the middle of each spring screw 3 is a spring, and the two ends are screw rods; the connecting block 4 is arc-shaped, and the two ends have threaded holes that match the spring screw 3. The adjustment block 5 is arc-shaped, with a threaded hole matching the spring screw rod 3 at one end, and a light hole with a diameter 0.3mm larger than the thread diameter of the spring screw rod 3 at the other end.

[0014] The six spring screws 3 are connected alternately and sequentially with the five connecting blocks 4, and the adjacent spring screws 3 and the connecting blocks 4 are screwed and fixed, and the head end and the end are both spring screws 3; The threaded holes are fixedly connected, and the end of the end spring screw rod 3 is installed in the light hole ...

Abstract

The invention discloses an inner hole supporting device for a thin-walled revolution-solid part. The inner hole supporting device for the thin-walled revolution-solid part comprises an adjusting nut (2), six spring threaded rods (3), five connection blocks (4) and an adjusting block (5). The six spring threaded rods (3) are alternately and sequentially connected with the five connection blocks (4). The spring threaded rod (3) at the head end is fixedly connected with a threaded hole of the adjusting block (5). The end of the spring threaded rod (3) at the tail end is installed in a smooth holeof the adjusting block (5) through the adjusting nut (2). According to the thin-walled revolution-solid part inner hole supporting device, the adjustable inner hole supporting device is adopted, so that the universality of a tool is improved, and the machinable area is also expanded when an inner hole supporting technology method is adopted.

Description

technical field [0001] The invention relates to an inner hole supporting device of a revolving body part, in particular to an inner hole supporting device of a thin-walled revolving body part. Background technique [0002] A thin-walled rotary part is a rotary part with a diameter-to-wall thickness ratio of not less than 20. When turning the outer circle and the end face, it is necessary to use the inner hole as the positioning and clamping reference, and usually use tooling such as an internally expanding mandrel. Support the inner hole of the thin-walled rotary parts. This clamping method increases the contact area when the parts are clamped, controls the elastic deformation of the clamping, and can obtain sufficient clamping force. Therefore, it can obtain a wide range of applications in turning processing. application. [0003] However, there are the following problems in the use of tooling such as internally expanding mandrels used for turning the outer circle and end ...
