Problems solved by technology

[0002] The inner hole of the cylinder liner of the engine must be chrome-plated before it is formed into a finished product. The chrome-plated hanger for the inner hole of the cylinder liner currently used has an auxiliary cathode at the joint with the axial positioning of the cylinder liner to prevent edge chrome plating caused by the tip discharge effect. The coating is relatively thick, but after repeated electroplating, it will be covered with chromium tumors. As a result, the chromium layer at the auxiliary cathode of the cylinder liner is often thinner. The positioning of the anode axis and the cylinder liner axis is manually adjusted. Regular adjustments are made. The insulating material used in the existing hangers is hard PVC. This material has poor permeability resistance. With the infiltration of chromic anhydride, the insulation performance decreases and it is easy to deform. The top opening of the chrome-plated hanger in the conventional cylinder liner Larger, the chromic acid mist volatilizes seriously during the electroplating process, so the requirements for the ventilation effect of the equipment are high, and the environmental pollution is more serious.

Abstract

The invention relates to a device to measure and regulate micro aeroboat engine, including engine speed measuring and sensing device, control box and rudder, and its character: the measuring and sending device has the structure: there is a magnet block fixed on the rotating shaft of the engine, there is a Hall sensor probe installed near the magnet, the output of the Hall sensor probe is connected to the control box through lead wires and that of the control box is connected to the rudder through lead wires. It can measure and control left and right engines of the aeroboat to make their speed consistent in a certain range, without manual operation and control, thus reducing labor strength of operators.

Description

1. Technical field [0001] The invention belongs to the technical field of engine cylinder liner processing machinery, and in particular relates to a chrome-plated hanger for the inner hole of a cylinder liner. 2. Background technology [0002] The inner hole of the cylinder liner of the engine must be chrome-plated before it is formed into a finished product. The chrome-plated hanger for the inner hole of the cylinder liner currently used has an auxiliary cathode at the joint with the axial positioning of the cylinder liner to prevent edge chrome plating caused by the tip discharge effect. The coating is relatively thick, but after repeated electroplating, it will be covered with chromium tumors. As a result, the chromium layer at the auxiliary cathode of the cylinder liner is often thin. The positioning of the anode axis and the cylinder liner axis is manually adjusted.
