Pipe welding turntable

Abstract

The invention discloses a pipe welding turntable which includes a spindle, a turntable, a casing, a bearing, a bearing block and a base. The casing is fixed to the base, the bearing block is fixed inthe casing, the turntable is fixed to the spindle and connected with the bearing through the spindle, and a column body of the spindle for a pipe to be connected in a sleeved mode extends on the uppersurface of the turntable. By implementation of the pipe welding turntable, the pipe welding turntable can be applied to welding operations on pipes with medium and small diameters (28mm<=phi<=114mm),the welding quality and welding efficiency of the pipes with the medium and small diameters can be effectively improved, and constructors' labor intensity is reduced.

Description

technical field [0001] The invention relates to a pipe welding turntable, in particular to a welding turntable device with a pipe diameter of 28mm≤φ≤114mm. Background technique [0002] In the welding process of the pipe, in order to ensure the welding quality of the pipe and the appearance of the weld seam, the transition is uniform, the welding positioner is usually used to drag the workpiece to be welded, so that the weld seam to be welded moves to the ideal position for welding operation . [0003] When the welding positioner is welding a pipe with a large outer diameter of φ>114mm, due to the large weld seam of the large pipe, the continuous welding time after clamping the pipe is very long, and the welding quality and welding efficiency are high. However, when welding small and medium-diameter pipes of 28mm≤φ≤114mm, due to the small diameter of the pipe and the short weld seam, the weld seam can be completed quickly after the small-diameter pipe is clamped on the w...

Problems solved by technology

However, when welding small and medium-diameter pipes of 28mm≤φ≤114mm, due to the small diameter of the pipe and the short weld seam, the weld seam can be completed quickly after the small-diameter pipe is clamped on the welding positioner, which eventually results in the need for small and medium-diameter pipes. Repeated work such as clamping, welding, loosening, clamping, welding, and loosening of the pipe

A lot of time is wasted on the clamping and loosening of the pipes, resulting in a lot of ineffective working hours, the labor intensity is also very high, and the welding efficiency cannot be effectively improved

In addition, due to the frequent operation of the welding positioner, the complex mechanical structure of the machine itself, and the easy fatigue and damage of electrical and electronic control components, the welding positioner has a high shutdown failure rate and a long maintenance time, which makes it impossible to continuously and efficiently put into welding work

[0004] It can be seen that the cost of welding pipes with small and medium diameters by welding positioners is relatively high: 1. Repeated clamping and welding work is required, which increases the time cost; 2. Repeated mechanical actions increase the labor intensity of workers. Low efficiency; 3. It is easy to cause fatigue of electronic control components of welding positioner, high failure rate of shutdown, and affect production efficiency
