An automatic flaring and rotary groove forming machine for automobile pipe fittings

Abstract

The invention discloses an automatic expansion and grooving molding all-in-one machine for vehicle pipe fittings. The machine comprises a machining platform, a machining device and a moving device; the machining device is fixed at one end of the surface of the machining platform; a moving cavity is formed in the machining platform; the moving device is fixed in the moving cavity; and the moving device consists of a moving motor, a first lead screw, a second lead screw, a transmission gear, a first tooth belt, a slide plate, a slide block, clamping arms and pipe end fixing pieces. Through the machining device, the replacement of an expanding top cone and a grooving cutter is realized; through a cooperating effect between the pipe end fixing pieces and the two clamping arms, the fixation ofpipes can be realized; through a feeding motion of the moving device, one ports of the pipes are expanded and grooved; and the two steps are performed on one device, so that the secondary positioningof the pipes is prevented, the machining precision is improved, the time needed by the secondary positioning is saved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of processing automobile pipe fittings, in particular to an automatic flaring and grooving forming integrated machine for automobile pipe fittings. Background technique [0002] In automobile processing and production, there are many places that need to use pipes. The pipes inside the car are generally connected by sockets, so the two ends of the pipes need to have different radii, because the overall radius of this kind of pipes is the same after the initial molding Therefore, it is necessary to further process one end of the pipe by flaring. [0003] In the existing pipe fittings processing, one end of the pipe is first flared, and then the inside of the mouth is processed with a spiral groove to facilitate screw connection. Generally, the two processing procedures of flare and spiral groove are processed independently. After flaring, the pipe needs to be repositioned for grooving processing. The secondar...

Problems solved by technology

[0003] In the existing pipe fittings processing, one end of the pipe is flared first, and then the inside of the mouth is processed with a spiral groove to facilitate screw connection. Generally, the two processing steps of flare and spiral groove are separately processed. After flaring, the pipe needs to be repositioned for grooving. The secondary positioning may cause positioning deviation, and the secondary positioning will lead to low processing efficiency. For this reason, we propose an automatic flared grooving for automobile pipe fittings. machine
