JPH08126914A - Deburring device of end face of metallic pipe - Google Patents

Abstract

PURPOSE: To automate the deburring work by advancing/retracting a deburring edge by a driving means relative to a metallic pipe to be held by a chucking means, and successively achieving the debutting on the inner and outer circumferences of the metallic pipe by an inner edge and an outer edge of a deburring edge. CONSTITUTION: A metallic pipe 2 is held by a chucking means 2. A deburring edge 4 is provided where its drive shaft is present on the axis of a metallic pipe 1 to be held by the chucking means 2, an inner edge 4a along the inner circumference of the metallic pipe 1 and an outer edge 4b along the outer circumference are respectively provided, and the inner edge 4a is projected forward of the outer edge 4b. The deburring edge 4 is advanced/retracted by a driving means. As the deburring edge 4 is advanced, burrs are first removed along the inner circumference of the metallic pipe 1 by the inner edge 4a, and the burrs are removed along the outer circumference of the metallic pipe 1 by the outer edge 4b with the inner edge 4a as the guide. The deburring of the metallic pipe 1 is automatically and efficiently achieved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention manufactures a welded structure using a metal pipe such as an intermediate link of an automobile, that is, after machining (cutting to a certain size and processing the end surface R), deburring, welding, and a bush outer cylinder. The present invention relates to an apparatus for deburring a metal end face in cases such as cases.

[0002]

2. Description of the Related Art Conventionally, in an example in which a milling process such as an intermediate link of an automobile is applied to an end portion and an outer cylinder of an elastic bush is welded to the end portion, the processed end portion of a metal pipe interferes with welding. Deburring has not been done completely to the extent that there is no. Only when there was a large burr that was deformed, a person dropped it with a file.

[0003]

If the welding is performed with the inner burr still present, the inner burr separates at the time of welding and becomes a ball and remains in the pipe, which causes a noise due to rolling. Further, the outer burr may be deformed outward (put in a pallet) depending on how to handle the pipe after processing, so that the outer burr does not follow the outer peripheral surface of the bush welding counterpart.

Even if a person merely drops the large burr with a file or the like, the deburring work has been a time bottleneck in the mass production flow work. The present invention aims to provide a device capable of reliably removing burrs in a short time.

[0005]

The present invention is a metal pipe 1
The chuck means 2 and the drive shaft 3 on the axis of the metal pipe held by the chuck means 2 have an inner blade 4a along the inner circumference of the pipe and an outer blade 4b along the outer circumference of the pipe. A deburring device for an end surface of a metal pipe, which is composed of a deburring blade 4 having a shape protruding forward from an outer blade and a driving means 5 for moving the deburring blade 4 forward and backward.

[0006]

According to the present invention, when the metal pipe 1 is gripped by the chuck means 2, the deburring blade 4 is advanced to the end surface of the metal pipe 1 by the driving means 5, and first the inner blade 4a is moved along the inner circumference of the pipe. The inner blade 4a serves as a guide on the inner circumference of the pipe, and the outer blade 4b is guided to the outer circumference of the pipe to remove the burr, so that all the burrs can be cleanly and instantly removed. Further, by mechanizing the supply of the metal pipe 1, deburring can be automated without human intervention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially cutaway side view of a deburring device for an end surface of a metal pipe of the present invention, and FIG. 2 is a front view. As shown in FIG. 4, this device is installed at a position where the metal pipe 1 having its tip rounded by milling is moved and supplied by a walking beam triangular stand 10. At that position, there is a clamp air cylinder 2a as a chuck means 2 for the metal pipe 1. There is a deburring blade 4 having a drive shaft 3 on the axis of the metal pipe held by the chuck means 2. Deburring blade 4
Consists of an inner blade 4a along the inner circumference of the pipe and an outer blade 4b along the outer circumference of the pipe, and the inner blade 4a projects forward from the outer blade 4b. An air cylinder 5a as a driving means 5 for moving the deburring blade 4 forward and backward.
There is.

3 (a) to 3 (c) show how deburring is performed by this apparatus. R-The finished work is lifted by the walking beam triangular stand 10 and moved horizontally to the position of this machine. The clamp air cylinder 2a of the chuck means 2 operates and clamps as shown in (a). As a result, the air cylinder 5a of the driving means is actuated to move the deburring blade 4 forward so that the inner blade 4a enters the pipe and deburrs the inner surface. When the deburring blade 4 further advances, the inner blade 4a serves as a guide and the outer blade 4b is guided to the outer periphery of the pipe to deburr as shown in (c). After that, the deburring blade 4 retracts and returns to the standby position. Then, the clamp air cylinder 2a is released and rises, the walking beam triangular base 10 rises and moves, and the metal beam 1 of the work is placed on the slope 11 to move to the next step.
In the next step, the metal pipe 1 is welded to the outer cylinder 6 of the bush as shown in FIG. 4, for example.

[0009]

According to the present invention, it is possible to deburr the entire inner and outer circumferences of a machined pipe end surface without manual work. In addition to the improvement of welding quality and homogenization, it can be incorporated into a part of the compound machine, which makes it possible to automate the production of welded structures using metal pipes.
