Specific embodiment
The angular positioning device of the utility model is used for the angular positioning of component of machine (workpiece), every convenient for making in assembly
The position consistency of a workpiece.The structure of the device includes workpiece rotating mechanism and detection normotopia mechanism, workpiece detection mechanism setting
In the top of workpiece rotating mechanism, workpiece rotating mechanism drives workpiece rotation, and detection normotopia mechanism passes through to the feature on workpiece
Point is detected, and exports electric signal, is controlled the operating of workpiece rotating mechanism, is determined angular position, make workpiece normotopia.
As shown in Figure 1, workpiece rotating mechanism includes main shaft 3, spindle drum 2, main axis device 1 and pallet 4.Main shaft 3 is logical
Bearing (bearing can also be using axle sleeve, the bushing etc. of centering) is crossed to be mounted on spindle drum 2 and connect with main axis device 1,
The rotation of 1 driving spindle 3 of main axis device.Main axis device 1 is using motor, decelerating motor or other rotating devices, such as gas
Dynamic rotation motor, hydraulic rotating motor etc. are capable of the controllable motor of continuous rotary type.Pallet 4 is connected on main shaft 3, with main shaft
3 rotate, and place the pending workpiece 11 angularly positioned in pallet 4, workpiece 11 positions in pallet 4.
Detecting normotopia mechanism includes fixed plate 10, probe 5, adjustment ring 6, spring 7, guide sleeve 8 and detection switch 9.Guiding
Set 8 is mounted in fixed plate 10.The middle part of probe 5 is sleeved in guide sleeve 8, and guide sleeve 8 is stretched out in upper part and lower part.Probe
5 lower part is provided with adjustment ring 6, and spring 7 is provided between adjustment ring 6 and guide sleeve 8, and spring 7 is sleeved on probe 5.Detection
Switch 9 is mounted on the upper outside in fixed plate 10 and being in probe 5.
Probe 5 is used to detect the angular position of workpiece, by characteristic point concave or raised on workpiece, so that probe 5
Height and position change.Adjustment ring 6 is used to adjust the decrement of spring 7.Adjustment ring 6 can be by being threaded onto probe 5
On, it can also be fixed on probe 5 by jackscrew, height and position of the adjustment ring 6 on probe 5 is adjusted.It is logical
The decrement of adjustment spring 7 is crossed to adjust the elastic dynamics of detection probe so that detection probe 5 smooth can set back and
Not disfiguring workpiece.Guide sleeve 8 play the guiding role to moving up and down for probe 5.Position of the detection switch 9 for detection probe 5 becomes
Change, to export electric signal.
The process that above-mentioned apparatus angularly positions workpiece is as described below.
The distance of probe 5 to rotating center is equal to characteristic point to the distance of rotation center, and adjustment is visited according to this
Needle 5 is in the surface of the characteristic point on workpiece 11, makes the characteristic point on the workpiece 11 being fitted into pallet 4 by probe 5.
Workpiece 11 is placed in pallet 4 by artificial or robot, the bottom end of probe 5 is pressed in by the effect of spring 7
On workpiece 11.Start main axis device 1, main shaft 3 rotates, and pallet 4 and workpiece 11 rotate with it.Probe 5 is in workpiece surface
Mobile, when the upper plane of workpiece 11 has a pit, when groove position turns to the position of probe 8, probe 8 can be in spring 7
Under the action of decline, the height and position of probe 5 will change, detection trigger switch 9 export electric signal, control main axis
Device 1 stops operating, and workpiece 11 is made to stop in the position, realizing angular positioning.
If workpiece surface is other feature point, such as protrusion, the height and position of probe 5 can equally change,
Meeting detection trigger switch 9 exports electric signal, and control main axis device 1 stops operating, and realizes angular position.
Since the characteristic point on identical workpiece 11 is consistent, it is achieved that each workpiece 11 is in same by above-mentioned apparatus
One angular position, when with other component assemblings, it is easy to accomplish the automation of assembling process.
