Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Referring to Fig. 1 and Fig. 2; The horizontal pick-up unit of the utility model axial workpiece; Comprise worktable 1, on worktable 1, be provided with two locating pieces, 15, two locating pieces 15 and be provided with the V-type groove that is used to place axial workpiece; Two locating piece V-type groove lines relative to both sides be provided with and drive axial workpiece 14 to be detected driving wheel 13 that rotates and the pinch roller 12 that is used for axial workpiece to be detected is pressed against two locating piece V-type grooves, driving wheel 13 and pinch roller 12 all are positioned at two locating pieces, 15 inboards.Among the embodiment, driving wheel is positioned at axial workpiece to be detected below, and pinch roller is positioned at axial workpiece to be detected top, convenient like this axial workpiece loading and unloading to be detected.Be respectively equipped with guidepost 2, two guideposts 2 in worktable 1 both sides and be positioned at locating piece 15 outsides, two guideposts, 2 upper ends are fixed with support 7, and support 7 has crossbeam 4, and crossbeam 4 two ends are enclosed within on the guidepost 2, and V-type groove line is positioned under the crossbeam on two locating pieces.Support 7 is provided with straight line driving mechanism 8 (like cylinder or fluid cylinder), and straight line driving mechanism 8 is connected with crossbeam 4 (through the piston rod of cylinder or fluid cylinder) to drive crossbeam and slides up and down along guidepost.At least two displacement transducers 3 (chart display is three) are installed on crossbeam 4; All displacement transducers 3 equidistantly are provided with and form a row at interval; Each displacement transducer is corresponding to the different position of axial workpiece length direction to be detected; Be that each displacement transducer detects workpiece different cross-sectional areas, detect error and improve detection efficiency avoiding.
Said locating piece is installed on the worktable through chute on the worktable or slide rail, and can slide along chute or slide rail, thereby can change the spacing of two locating pieces, to adapt to the axial workpiece of different length, makes this device have the detection versatility.
Said crossbeam 4 is provided with pressing plate 6, is provided with cushion pad 5 between pressing plate 6 and the crossbeam 4, and straight line driving mechanism 8 is connected with crossbeam 4 through pressing plate 6, the influence that can avoid the rigidity contact that measurement is brought.
As a concrete mounting means; On crossbeam 4, be provided with the through hole of installation position displacement sensor; Displacement transducer 3 is sleeved on that spring expands in the chuck 10 and the spring through nut structure expands, and chuck cover 11 makes that spring expands that chuck 10 is held displacement transducer 3 tightly, again the spring chuck 10 that expands is installed in the through hole and through set nut 9 and lock onto in the through hole.Through hole can be a threaded hole, and the bloated chuck of spring has the external thread structure of coupling and is connected in the through hole through external thread rotary.This structure is convenient to sensor and is installed on the crossbeam reliably, and installs and take off all more convenient.Sensor is installed accurately, is put in place, can avoid the detection error of bringing because of the equipment installation question well.
This device mainly drives three parts by clamping workpiece, workpiece sensing and workpiece and forms.
Clamping workpiece partly utilizes the locating piece of two band V-shaped grooves that workpiece (being axial workpiece to be detected) is positioned.The axial location of not drawing in the drawings, and when carrying out glitch detection, need it be positioned, this is because in measuring process, can there be axial motion in workpiece by after pinch roller compresses in the workpiece drive unit.
Workpiece crouches and puts locator meams commonly used when being the axial workpiece detection.It is to embody its benchmark with external cylindrical surface, and is simple in structure, easy for installation, is easy to realize automatic charging and feeding.But because possibly relate to the slender axles part, crouch and to produce distortion because of the deadweight of workpiece when putting, after its rotation, form drum type.But, as long as regulate two distances between the locating piece, just can address this problem.
Workpiece sensing partly is to utilize the sensor of straight line driving mechanism (such as hydraulic cylinder) drive fixing on crossbeam; It is moved up and down on guidepost; Realize carrying out the reading operation after sensor arrives the detection position; And after measuring completion, make sensor leave the detection position, make things convenient for picking and placeing of workpiece.
The measuring method that adopts is 3S90 °, must know the seamed edge number of measured axis this moment, and the seamed edge number is that the number of the sine wave that occurs when measuring is confirmed here.
It is to use the drive wheel Workpiece Rotating that workpiece drives, and with the measurement of realization to shaft section, and driving wheel is by step motor drive.Driving wheel is placed on the locating piece inboard, and can float.Workpiece is applied certain power (acting on the locating piece) being provided with pinch roller above the workpiece, this power is unsuitable much, as long as workpiece is reliably contacted with driving wheel.
Compare with general type of drive, driving wheel is a right cylinder, and processing is simple, precision is high, can seamlessly realize forward and reverse transmission, can under power transmission situation continuously, infinitely regulate ratio of gear, and when one of driving wheel was nonmetallic materials, noise was low.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
