Pipe hole cutting device for simple type metal pipe fitness

Abstract

The invention provides a pipe hole cutting device for a simple type metal pipe fitness. The device is characterized by comprising a positioning device for positioning and mounting a workpiece and a cutting device for machining holes, wherein the positioning device comprises a N-shaped positioning frame, a left clamping plate, a right clamping plate, a left sliding plate and a right sliding plate;the left clamping plate and the right clamping plate are arranged at the lower ends of the two sides of the positioning frame in hinged mode, the lower ends of the left sliding plate and the right sliding plate are connected with the left clamping plate and the right clamping plate in hinged mode, and the upper ends of the left sliding plate and the right sliding plate are slidably arranged on thepositioning frame; the positioning frame is provided with a drive device, wherein the drive device is used for driving the upper ends of the left sliding plate and the right sliding plate to simultaneously move in the same or back direction so as to drive the left clamping plate and the right clamping plate to rotationally clamp the workpiece; and the positioning frame is provided with a mountingrod which is co-axially and parallelly with the workpiece, and the cutting device is mounted at the other end of the mounting rod. According to the pipe hole cutting device for the simple type metalpipe fitness, clamping cambered surfaces of the left clamping plate and the right clamping plate cooperate with clamping wheels so as to position and clamp the workpiece, so that the workpiece can bein centering mounting while being clamped, and therefore the device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a simple metal pipe hole cutting device. Background technique [0002] The development of cutting machines must meet the requirements of the development of modern machining industry. Cutting machine is divided into flame cutting machine, plasma cutting machine, laser cutting machine, water cutting and so on. Plasma cutting machine can cut all kinds of metals that are difficult to cut by oxygen cutting with different working gases, especially for non-ferrous metals, the plasma cutting speed is fast, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone. application. However, the existing cutting machines are complex in structure, expensive in cost, and occupy a large area. They are generally suitable for large-scale machine parts processing plants. For some occasions where a small number of holes are processed, there...

Problems solved by technology

However, the existing cutting machines are complex in structure, expensive in cost, and occupy a large area. They are generally suitable for large-scale machine parts processing plants. For some occasions where a small number of holes are processed, there is no economic value in purchasing large-scale equipment, and the purchase cost is relatively high.
