Embodiment Construction

[0010] Such as figure 1 As shown, a is the thin-walled aluminum tube to be processed, b is the processed thin-walled aluminum tube, c is the end face of the thin-walled aluminum tube, and the wall thickness is very thin.

[0011] Such as figure 2 As shown, the left positioning mandrel (1) and the right positioning mandrel (6) are connected together with the support tube (2) in the form of interference fit. Piston rings (3) and O-shaped rubber sealing rings (4) are alternately set on the support tube (2).

[0012] During work, put the thin-walled aluminum tube (5) on the support tube (2), and insert the left positioning mandrel (1) together with the thin-walled aluminum tube (5) into the positioning hole of the positioning fixture. Then, load onto the pressing plate (7) on the right side, and the clamping jig (8) is pressed on the pressing plate (7) by the toggle clamp.

[0013] The pressure plate (7) moves to the left, pushing the piston ring (3) to move to the left in tur...

Abstract

The invention provides a quick clamp for milling a thin-walled tube type workpiece by using a method for combining a core shaft, a piston ring and an O-shaped rubber sealing ring and aims to solve the problem that a thin-walled aluminum tube commonly used for manufacturing an air-conditioning evaporator and a condenser is greatly deformed often during milling. When a fixture clamps the machined thin-walled aluminum tube, the O-shaped rubber sealing ring is deformed to a certain extent and is tightly pressed against the inner wall of the thin-walled aluminum tube, so that the rigidity of the thin-walled aluminum tube is improved, the deformation resisting capacity is improved, and the thin-walled tube type workpiece is prevented from being vibrated and deformed when being milled.

Description

Technical field: [0001] The present invention is a kind of method that is applied to various milling processing equipment and uses the method of combining the mandrel, the piston ring and the O-shaped rubber sealing ring to prevent the thin-walled workpiece from vibrating and deforming when milling the thin-walled tubular workpiece. fixture. Background technique: [0002] Air conditioning is an important device widely used in refrigeration and air conditioning systems in automobiles, tractors, locomotives, ships, and petroleum, chemical, pharmaceutical and other industries. The new air conditioner is made of aluminum, which is especially suitable for the working environment with high humidity, high temperature, oil pollution and serious corrosion, and has strong anti-rust and anti-corrosion capabilities. At present, the annual output of automobiles has exceeded 18 million. With the improvement of living standards, the market demand for air conditioners is also expanding. A...
