Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is described in further detail:

[0014] Reference attached figure 1 As shown, the tool used for riveting the inner hole of the shell outlet pipe mainly includes rolling block 1, connecting rod 6, bushing 2, support 3, cam 4, handle 5 and crank 7 and other parts. When the rolling block 1 can rotate along the central axis of the support 3, the cam 4 can move to the outside under the action of the protrusions of the two cylindrical pins of the support 3.

[0015] There is a square hole with the same shape as the connecting rod 6 in the middle of the rolling block 1, the connecting rod 6 is threaded to the handle 7, the bushing 2 is threaded to the support 3, the connecting rod 6 passes through the inner hole of the bushing 1, There are two cylindrical pin protrusions on the outside of the support 3, the cam 4 is on the outside of the support 3, the connecting rod...

Abstract

The invention discloses a tool for spinning riveting of an inner hole of a shell-type wire outlet pipe. The structure of the tool mainly comprises a rolling block 1, a bush 2, a support 3, a cam 4, ahandle 5, a connecting rod 6, a crank 7 and other parts. By means of the tool, the inner hole of the wire outlet pipe of a shell can be conveniently screwed; and compared with the prior art, the toolhas the advantages of being convenient and rapid, firm in riveting and high in universality.

Description

technical field [0001] The invention belongs to the technical field of processing, and relates to a tool for screw riveting of the inner hole of an outlet pipe of the shell type. Background technique [0002] For aviation filters, temperature control boxes and other casing products, the casing needs to be riveted with the outlet pipe. Since the riveting position is inside the casing and the inner hole of the outlet pipe, if the general riveting method is used, The working area is restricted by the surrounding walls of the enclosure, making riveting difficult to accomplish. Therefore need to study a kind of tool that can conveniently and quickly rivet shell type outlet pipe. Contents of the invention [0003] The present invention is designed to address the shortcomings of the above-mentioned shell-type outlet pipe spin riveting technology, and provides a tool that can be used for shell-type outlet pipe inner hole spin riveting. [0004] The purpose of the present inventi...
