Bent pipe welding, positioning and locking device

Abstract

The invention provides a bent pipe welding, positioning and locking device. The device comprises a base; a first support base, a second support base and a bent pipe positioning mechanism are mounted on the base in sequence from right to left side by side; a branch pipe positioning mechanism is mounted between the first support base and the second support base; a first locking fixture is mounted onthe second support base; the bent pipe positioning mechanism is mounted on the left side of the second support base; and a second locking fixture is fixed on the side wall of the bent pipe positioning mechanism, and is positioned below a positioning and locking block. The bent pipe welding, positioning and locking device can realize quick positioning and butt joint of pipe fittings with differentshapes and guarantee the butt joint quality through presetting the first support base, the second support base, the first locking fixture, the bent pipe positioning mechanism and the second locking fixture; the branch pipe positioning mechanism can guarantee welding angles of a branch pipe with a first pipe tube and a second pipe tube to meet requirements; and the first locking fixture and the second locking fixture can realize quick locking of a straight pipe and the second pipe tube.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to an elbow welding positioning and locking device. Background technique [0002] In the car structure, many parts belong to the tube and bracket. There are many types and shapes, and most of them require the use of tack welding technology. The multi-channel oil pipe is a key part of the automobile engine system, and its shape is as figure 1 As shown, the multi-channel oil pipe is generally welded by a first tube 81, a straight tube 82 with a branch 85, an elbow 83 and a second tube 84, wherein the first tube 81 and the second tube 84 are used for Butt the other parts of the engine, the branch pipe 85 on the straight pipe 82 is used for the butt joint of the branch oil circuit, so the welding angle of the branch pipe 86 on the straight pipe 82 and the first tube 81 and the second tube 85 must be accurate, once the angle appears If the above error is not correct, the...

AI Technical Summary

Problems solved by technology

This welding method mainly has the following defects: 1) because the first pipe tube 81, the straight pipe 82 with branch pipe 85, the bent pipe 83 and the second tube tube 84 are all circular pipe fittings, which are easy to slide and difficult to fix. Moreover, there are many welding positions and the size of the pipe fittings is not large, which easily leads to missing welding or poor welding; 2) the welding angle of the branch pipe 85 and the elbow pipe 83 is difficult to manually grasp, and a slight vibration will cause welding errors and cause the pipe fittings to be scrapped; 3) The depth of the straight pipe 82 inserted into the first tube 81 and the depth of the bent tube 83 inserted into the second tube 84 are not easy to control, which may easily lead to differences in the dimensions of the produced multi-channel tubing, and cannot guarantee the same batch Product quality; 4) The alignment steps of pipe fittings are cumbersome and the welding efficiency is low, which has become more and more difficult to meet the requirements of modern production of car light brackets

However, in this application, it can only be used for ordinary pipe fittings, and it is impossible to achieve accurate alignment of the welding angle between the straight pipe with the branch pipe and the elbow pipe, and its locking requires additional power such as a cylinder, the locking speed is slow, and the power consumption is large.
