Technical field
The utility model relates to the machine tools field, particularly relates to a kind of pneumatic cutter sweep that can process aircraft skin.
Background technology
The effect of aircraft skin is to keep aircraft configuration, makes it to have the layer of aluminum alloy of good aerodynamic characteristics.Covering bears behind the aerodynamic effect force transmission to the fuselage wing skeleton that links to each other, stressed complexity, and covering directly contacts with the external world in addition, so not only require skin material intensity height, plasticity good, also requires smooth surface, and higher resistance to corrosion is arranged.
At present, aircraft skin is added man-hour, use a kind of pneumatic cutter sweep.This pneumatic cutter sweep comprises cutter body and has the guide rail of the gear teeth that guide rail is consistent with the surface curvature of covering; Cutter body is provided with three gears with the guide rail engagement, one of them gear is a driving gear, and it is by the corresponding driving device drives, and two other is a driven gear, cooperate driving gear to clamp guide rail, driving gear makes cutter body along guide rail movement under the driving of driving arrangement.Cutter body also comprises the air motor of cutting blade and driving cutting blade etc.Cutting blade adopts grating to measure its position and show by the panel numeral, and the staff can show that numerical value accurately regulates the depth of cut of cutting blade according to panel.
During the processing aircraft skin, skin material to be processed is installed and fixed, then cutter body is installed on the guide rail, make three gears and guide rail engagement by the handle of regulating clamp mechanism, adjust the parameter of cutting machine, the driving arrangement of sequence starting cutting blade and driving gear is processed.Because the clamping force between gear and the guide rail is regulated by operating personnel's experience, often take place because of insufficient clamping force, driving gear and guide rail engagement are not in place, beat, dally; Or the excessive exercise load that causes of clamping force is big, the flex point place serious wear that guide rail curvature changes, even gear spring tooth phenomenon appears.Above-mentioned phenomenon all can cause the product quality of cut face relatively poor, makes product processed not meet instructions for use.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of clamping force that can accurately regulate clamp mechanism is provided, and then controls the pneumatic cutter sweep of clamping force between driving gear and the guide rail.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of pneumatic cutter sweep, the guide rail that comprises panel, is installed in cutting blade on the cutter body and driving gear and cooperates with driving gear, cutter body is provided with the clamp mechanism of regulating driving gear and guide rail clamping force, and this clamp mechanism is provided with the clamping force display unit.
Preferably, described clamp mechanism comprises the slide block that is connected with the driving gear driving arrangement, the handle and the spring of adjusting slider, and spring housing is contained on the handlebar, and the cutter body appropriate section is provided with the slide rail that cooperates with slide block; Described clamping force display unit comprises the clamping force sensor, and the clamping force sensor is installed in the spring terminal that closes on handle, and clamping force sensor and panel electrically connect.
Preferably, described clamping force sensor is the KZ-YLF pressure sensor.
Preferably, the driving arrangement of described driving gear is the air motor of adjustable speed.
Preferably, described driving gear is a herringbone bear.
Preferably, the depth of cut of cutting blade adopts the grating location, and grating and panel electrically connect.
Compared with prior art, the utlity model has following advantage: because on the clamp mechanism of regulating driving gear and guide rail clamping force, the clamping force display unit is set, can observe the size of driving gear and guide rail clamping force intuitively by this clamping force display unit, realize accurate adjusting its clamping force.Thereby effectively avoided because of insufficient clamping force, driving gear and guide rail engagement are not in place, the situation of beating, dallying occurs; Perhaps clamping force is excessive, causes exercise load big, the flex point place serious wear that guide rail curvature changes, the situation of gear spring tooth.And then effectively overcome because of above-mentioned phenomenon and caused the underproof problem of product quality of cut face.
