Description
Technical field
The present invention relates to detect device, relate in particular to power value detection device.
Background technology
Wheel founds Vehicle Processing clamping force detector, be a kind of special detection aluminum-alloy wheel on vertical lathe during machining, fixture applies the detection device of clamping force size to wheel.Under normal circumstances, to wheel cutting forming, needing by wheel clamping on lathe spindle, due to reasons such as wheel diameter dimension are little compared with big and clip clamp force, easily causing wheel comes off when main shaft high speed rotating, and bumper car accident occurs.
Summary of the invention
Therefore, it is an object of the invention to provide a kind of wheel and found Vehicle Processing clamping force detector, it is possible to the needs of clamping force value detection when meeting vertical Vehicle Processing.
In order to realize the object above of the present invention, it is provided that following technical scheme: a kind of wheel founds Vehicle Processing clamping force detector, including chuck, parallels, cylinder, fixture, resistance strain gage.
A preferred aspect of the invention, chuck are uniformly distributed parallels A, parallels B, parallels C by 120 jiaos, according to 3 principles determining a plane, it is ensured that position completely between wheel and chuck.
In a preferred aspect of the invention, it is uniformly distributed clamping cylinder A clamping cylinder B, clamping cylinder C by 120 jiaos on chuck, under compressed-air actuated effect, clamping cylinder A, clamping cylinder B, clamping cylinder C promote plunger to drive fixture A, fixture B, fixture C to do clamping movement so that wheel is in close contact with parallels A, parallels B, parallels C.
In a preferred aspect of the invention, parallels A, parallels B, parallels C are hollow hexahedron, are active face with chuck contact surface, and active face arranges sealing device, it is ensured that add cutting fluid in man-hour and penetrate into parallels A, parallels B, parallels C inner chamber.
The resistance strain gage as force value detecting element is posted on a preferred aspect of the invention, parallels A, parallels B, parallels C inner chamber.Each resistance strain gage is respectively connected in the strain bridge of independent 1/4th, and the resistance of foil gauge selects 350 ohm；The bridge of detection force value is 3 1/4th bridges, and the resistance value of bridge is 350 ohm.
When fixture A, fixture B, fixture C by wheel clamping on parallels A, parallels B, parallels C time, clamping force can force parallels A, parallels B, parallels C to produce miniature deformation, thus cause the change in resistance of resistance strain gage.By detecting the change of 3 foil gauge resistance values, draw the clamping force acted on parallels A, parallels B, parallels C.If 3 force value are within ± 5%, then can be determined that clamping is effectively；Whether action is effective otherwise to need to check clamping cylinder A, clamping cylinder B, clamping cylinder C, and clamping wheel again.
The air pressure acting on clamping cylinder is 0.4-0.5MPa, and too small meeting causes insufficient clamping force, crosses conference and causes wheel rim to be crushed.
Technical scheme has advantages below: 3 parallels use hollow structure, it is simple to clamping force is transmitted；And it is easy to the stickup of foil gauge.It is active face that 3 parallels use with chuck installed surface, and is provided with sealing device, it is possible to prevent cutting fluid from penetrating into parallels inner chamber, it is possible to protective resistance foil gauge is corroded.Use resistance strain gage and resistance bridge as power value detection device, there is simple in construction, safe and reliable advantage, disclosure satisfy that the testing requirement of clamping force simultaneously.
Accompanying drawing explanation
Hereinafter, embodiment of the present invention are described in detail in conjunction with accompanying drawing.
Fig. 1 founds Vehicle Processing clamping force detector structural representation for a kind of wheel.
Fig. 2 founds Vehicle Processing clamping force detector structure A-A schematic diagram for a kind of wheel.
Wherein 1-fixture A, 2-chuck, 3-parallels A, 4-parallels B, 5-fixture B, 6-fixture C, 7-parallels C, 81-cylinder A, 82-cylinder B, 83-cylinder C, 9-plunger, 10-resistance strain gage.
Detailed description of the invention
Describe wheel below in conjunction with the accompanying drawings in detail and found Vehicle Processing clamping force detector.
Wheel founds Vehicle Processing clamping force detector, including fixture A1, chuck 2, parallels A3, parallels B4, fixture B5, fixture C6, parallels C7, clamping cylinder A81, cylinder B82, cylinder C83, plunger 9, resistance strain gage 10.
It is uniformly distributed parallels A3, parallels B4, parallels C7 by 120 jiaos, according to 3 principles determining a plane, it is ensured that position completely between wheel and chuck 2 on chuck 2.It is uniformly distributed clamping cylinder A81, clamping cylinder B82, clamping cylinder C83 by 120 jiaos on chuck 2, under compressed-air actuated effect, clamping cylinder A81, clamping cylinder B82, clamping cylinder C83 promote plunger 9 to drive fixture A1, fixture B5, fixture C6 to do clamping movement so that wheel is in close contact with parallels A3, parallels B4, parallels C7.
Parallels A3, parallels B4, parallels C7 are hollow hexahedron, are active face with chuck 2 contact surface, and active face arranges sealing device, it is ensured that add cutting fluid in man-hour and penetrate into parallels A3, parallels B4, parallels C7 inner chamber.
3 resistance strain gages 10 being arranged on parallels A3, parallels B4 and parallels C7 inner chamber produce miniature deformation under the effect of clamping force, resistance value changes, 3 then corresponding detection bridge output signals of telecommunication, calculate correspondingly clamping force value size by amplifying circuit, and be reflected in digital form on the control interface of lathe.The resistance of foil gauge selects 350 ohm；The bridge of detection force value is 3 1/4th bridges, and the resistance value of bridge is 350 ohm.
Act on after the force value on parallels A3, parallels B4 and parallels C7 detects, by F3 role of delegate clamping force on parallels A3, by F4 role of delegate clamping force on parallels B4, by F7 role of delegate clamping force on parallels C7.Now rotating machine tool chief axis, whether action puts in place for gauging fixture A1, fixture B5 and fixture C6, if any one action is not in place in fixture A1, fixture B5 and fixture C6, then needs to re-execute pinching action.
After as gauging fixture A1, fixture B5 and fixture C6, action puts in place, now the size of F3, F4 and F7 should be close, generally about 2500N, and deviation be maintained at F3, F4 and F7 meansigma methods 5% within.
Then successively fixture A1, fixture B5 and fixture C6 being applied pulling force with hand-held strain gauge, when the indicating value of hand-held strain gauge arrives 50Kg, fixture A1, fixture B5 and fixture C6 should not have loosening sign.
Now, the effective reference value that can F3, F4 and F7 be clamped as wheel, i.e. every time during clamping wheel, is referred to the size of F3, F4 and F7, it may determine that go out whether wheel is effectively clamped, and main shaft need not be rotated and be examined in fixture 1, fixture 5 and fixture 6 whether action puts in place.
Using the present invention that 1000 wheels are clamped detection, result shows, 1000 wheels, the clamped condition of more than 99%, can accurately check out, is fully able to meet clamping force detection needs, and decrease human reviewing time, reduce labor strength, improve labor productivity.
The air pressure acting on clamping cylinder is 0.4-0.5MPa, and too small meeting causes insufficient clamping force, crosses conference and causes wheel rim to be crushed.
