Constant-pressure automatic compensation system of aluminum alloy hub deburring machine

Abstract

The invention discloses a constant-pressure automatic compensation system of an aluminum alloy hub deburring machine, wherein a processing platform, an upper hair brush plate, a lower hair brush plate, an upper lifting gas cylinder and a lower lifting gas cylinder are arranged on a machine frame in a positioning way; the upper lifting gas cylinder and the lower lifting gas cylinder are respectively used for driving the upper hair brush plate and the lower hair brush plate to act; proportional control valves are connected between the gas inlets of the upper lifting gas cylinder and the lower lifting gas cylinder and a gas source respectively; a pair of pressure sensors are also arranged between the gas inlets of the upper lifting gas cylinder and the lower lifting gas cylinder and the gas source; the pressure sensors are respectively used for sensing gas pressure signals at the gas inlets of the upper lifting gas cylinder and the lower lifting gas cylinder, and transmitting the gas pressure signals to a controller; the controller implements analysis and calculation on the gas pressure signals and controls the flow rate of gas flowing out from the two proportion control valves, so that the condition that the upper hair brush plate and the lower hair brush act by the constant-pressure push of the upper lifting gas cylinder and the lower lifting gas cylinder can be guaranteed; therefore, not only the problem that not all burs are removed due to insufficient pressure of the upper hair brush plate and the lower hair brush plate, but also the problems that due to overlarge pressure of the upper hair brush plate and the lower hair brush plate, a hub is scrapped, and the service lives of the upper hair brush plate and the lower hair brush plate are shortened can be prevented.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, and specifically provides a constant pressure automatic compensation system for an aluminum alloy wheel hub deburring machine. Background technique [0002] At present, the wheel hub processing production line in the automobile industry is composed of casting machines, drilling machines, heat treatment machines, machining centers, and coatings. That is: the molten aluminum is die-cast into a wheel hub through a casting machine, and then heat-treated to adjust the quality of the wheel hub, then finished by a machining center, and finally sprayed with paint. In the processing and manufacturing engineering of mechanical parts, even the finishing process cannot avoid the occurrence of burrs. The existence of burrs will have a negative impact on the processing accuracy, assembly accuracy, processing positioning and appearance quality of the parts. Parts with a painted layer wi...

Problems solved by technology

This method can reduce the labor force, but the up and down pressure of the two brushes in this method is uncontrollable. When the pressure is too small, the hub burr brush will not be clean and the work efficiency will be reduced; when the pressure is too high, it will cause over brushing, The hub is scrapped and the brush is easy to wear, which increases the cost
