Thin-wall pipe fitting excircle machining clamp

Abstract

The invention discloses a thin-wall pipe fitting excircle machining clamp which comprises a mandrel, a jacket and an ejector bushing. An elastic conical head with a big-diameter end outward is arranged at the end of the mandrel, the jacket is arranged on the mandrel in a sleeved manner, a protrusion is arranged on the outer wall of the jacket, a tensioning sleeve is arranged at a position, on the inner side of the protrusion, on the outer wall of the jacket in a sleeved manner, a group of pressurizing holes are formed in the jacket, the ejector sleeve is arranged on the mandrel in a sleeved manner and positioned on the inner side of the jacket, two barrels are arranged on the outer wall of the ejector sleeve, central lines of the barrels are positioned on a same straight line, a spring is arranged at the bottom end of each barrel, an ejector column is arranged at the end of each spring, and a locking nut used for locking the mandrel is arranged at the end, away from the jacket, of the ejector sleeve. The technical defects that an existing thin-wall pipe fitting clamping device is prone to damaging the outer wall of a thin-wall pipe fitting and incapable of completing machining of the thin-wall pipe fitting at one step are overcome, and the thin-wall pipe fitting excircle machining clamp is less prone to damaging the outer wall of the thin-wall pipe fitting and capable of completing machining of the thin-wall pipe fitting at one step.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a jig for processing the outer circle of a thin-walled pipe fitting. Background technique [0002] At present, in the production process of automation equipment, thin-walled pipe fittings are usually used, and in order to make the thin-walled pipe fittings better cooperate with other parts in the equipment, it is usually necessary to process the outer circle of the thin-walled pipe fittings. When processing thin-walled pipe fittings, it is necessary to use a clamping device to clamp and position the thin-walled pipe fittings. At present, the clamping device for processing thin-walled pipe fittings is usually a three-jaw chuck. The outer wall clamps the thin-walled pipe fittings. However, since the pipe wall of the thin-walled pipe fittings is relatively thin, when the three-jaw chuck clamps the thin-walled pipe fittings, it is easy to cause the hollow pipe wall of...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a thin-walled pipe that is not easy to damage the outer wall of the thin-walled pipe, and aims at the technical defects that the existing thin-walled pipe clamping device easily damages the outer wall of the thin-walled pipe and cannot complete the processing of the thin-walled pipe at one time. Thin-walled pipe fittings outer circle processing fixture that can complete processing of thin-walled pipes at one time
