Formation of the present utility model such as accompanying drawing 1: by afterburning stepper motor (1), secondary gear gearing-down (2), ball wire bar pair (3), boosting-rod (4), detect position (5), piece-sending disc (6) send part stepper motor (7), send part gear drive (8), conduit (9), sorting turning bucket (10), sorting stepper motor (11), load sensor (12), the cunning of load bar (13) and inductosyn--scale (14) is formed.
In conjunction with the accompanying drawings principle of work and process are made brief description for the ease of implementing.
This machine primary structure such as accompanying drawing 1.Afterburning stepper motor (1) rotates by the ball screw that secondary gear gearing-down (2) drives in the ball wire bar pair (3), ball screw is fixed in the axial direction, nut is fixed in a circumferential direction, so, the rotation of ball screw moves axially nut, the boosting-rod (4) that is fixed on the nut just rises and descends, and realizes giving detection springs afterburning and unloading, by cunning--and scale (14) is measured the boosting-rod height and position.Send part stepper motor (7) to drive piece-sending disc (6), send into tested spring to the boosting-rod below by beat by sending part gear drive (8).Tested spring is after stressed, by load bar (13) pressure is reached load sensor (12), comparison according to test and microcomputer operational data size, microsystem commander sorting stepper motor (11) goes to corresponding position, makes tested spring among conduit (9) and sorting turning bucket (10) are fallen the corresponding container that connects material.
A circulation beat of the present utility model is summarized as follows: (electing example as with the rigidity branch).
Put count → send part → boosting-rod reduce to first point → test power reading →
The Control System of Microcomputer of electrical appliance part such as accompanying drawing 2, concrete control interface is seen accompanying drawing 4.System controlled by computer partly adopts the controller of TP-801 single card microcomputer (commercially available prod) as complete machine, 12 A/D change-over panels of control, digital display driver plate, motor-driven plate, counter drive plate, inductor interface board synchronously.The D.C. regulated power supply plate.By the amplification of above-mentioned part realization to sensor signal, the sampling of analog quantity, maintenance and A/D conversion, after finishing digitized processing, thereby the rigidity of calculating and specified rate compare functions such as finishing automatic sorting, counting.
Control circuit adopts active power filtering photoelectricity to isolate and the digital filtering anti-interference method has improved whole aircraft reliability; In addition, the range of application that has enlarged electric-control system is handled in the normalization on circuit; Aspect software, adopt ordering bubbling method to handle, improve the precision of measurement and the stability of indicating value, in addition, handle the safe and reliable work of complete machine that guarantees by the antioverloading of software to sampled data.
Displacement measurement element such as accompanying drawing 5.Adopt the present domestic displacement transducer of its ratio of precision of inductosyn (commercially available prod) to want height and stable performance.But because the logic high of output binary-coded decimal is the 12V(CMS circuit), still through the level conversion device, its logic high is converted to 5V and the use of native system coupling.In order further to improve the displacement readings precision.Also having adopted the compound filter method promptly to remove the maximal value of one group of number, minimum value on the software carries out arithmetic mean in the middle of taking out and just is true value.
Pressure survey such as accompanying drawing 6 by load sensor output, arrive latch through preposition amplification filtering, sampling, maintenance, mould/number conversion.Physical quantity is transformed into for computer-controlled digital quantity.Native system adopts 12 AD1210 device all more much higher than general 8 its precision of AD device that adopt and resolution.Software except that adopting arithmetic filtering, also adopts methods such as limit filtration when peek.
Separator possesses manually and two kinds of functions of automatic measurement.Its flow process such as accompanying drawing 3.
Automatic part: adopt modular structure to realize putting number, starting and stop three kinds of functions.Put fractional part and finish and accept panel data, carry out work such as difference computing and code conversion.Actuating section is the core of whole Automatic Cycle sorting, and it is made of the experimental process program, as accompanying drawing 7.Mainly finish driving, the displacement of main motor, the processing of pressure physical quantity, send the signal of feeding blanking, the count signal of message register.When stopping partly being a loop ends, differentiate control panel " automatically " key by program and discharge not,, stop counting and entering waiting status if release then stops the motor walking.
Manual part: the button of being differentiated on the control panel by program " makes progress " or " downwards ", and " making progress " then the main motor of afterburning parts upwards makes a move, and " downwards " then makes a move downwards.When main motor does not need the crawl walking,, and show after handling with regard to the data of measuring pressure sensor.Thereby can easily finish the work of the demarcation of force transducer.Also means of providing convenience for the upper and lower debugging of afterburning parts.
The driving of stepper motor, display driver and power circuit etc. all adopt general universal circuit, and relevant books have detailed introduction, repeat no more here.
Introduce a kind of spring sorting machine important technological parameters that the inventor trial-produces successfully below:
