Abstract
The utility model relates to a steel ball surface unfolding device. As a main part of a bearing, surface defect of a steel ball has extremely important influence on the precision, the operation property, the service life and the like of the bearing. Currently, in the bearing industry, detection on the surface defect of the steel ball still adopts a traditional artificial visual examination method, and the accuracy and stability can not be guaranteed. The steel ball surface unfolding device comprises a control unit which comprises a reset module, wherein the reset module corresponds to a microcontroller, and the microcontroller respectively corresponds to a stepping motor I (6), a stepping motor II (10), a DC motor (2) and a keyboard module; and the control unit is connected with a transmission mechanism. The steel ball surface unfurling device is used for non-contact detection on the surface quality of the steel ball.
Description
Technical field:
The utility model relates to a kind of steel ball sphere expanding unit, belongs to the non-contact detection field of steel ball surface quality.
Background technology:
Steel ball is as the critical part of bearing, and its surface imperfection is to all there being fundamental influence in precision, behavior in service and serviceable life etc. of bearing.At present, in bearing industry, traditional artificial visual method of inspection is still adopted in the detection of steel ball surface defect, its accuracy and stability all are difficult to guarantee.Therefore the steel ball surface defect detection technique is the important topic that industry is paid special attention to always.One of them main gordian technique is exactly the expansion of steel ball sphere.
Summary of the invention:
The purpose of this utility model provides a kind of for making the steel ball steel ball sphere expanding unit that sphere fully is exposed in testing process.
Above-mentioned purpose realizes by following technical scheme:
Steel ball sphere expanding unit, its composition comprises: control module, described control module comprises reseting module, the corresponding microcontroller of described reseting module, described microcontroller is corresponding stepper motor I, stepper motor II, direct current generator, Keysheet module respectively, and described control module is connected with gear train.
Described steel ball sphere expanding unit, described gear train comprises: expansion dish, rolling disc, described expansion dish is connected with the direct current generator with motor cover, and described motor cover is connected with closed slide, and described closed slide is connected with cam;
Described rolling disc is connected with rotor wheel, and the described rotor wheel outside is connected with axle sleeve.
Described steel ball sphere expanding unit, described stepper motor II is connected with rolling disc; Described stepper motor I is connected with described cam; Direct current generator is connected with the expansion dish.
The beneficial effects of the utility model:
1. the utility model does not have quick-wear part to the very little expanding unit of the wearing and tearing of steel ball surface, and the life-span is long; The disk eccentric motion that forms steel ball fully launches the steel ball sphere.
2. when having solved expanding wheel expansion steel ball sphere, sphere abrasion rate height, the problem that the expanding wheel life-span is low, the sphere sheetage is low.
Description of drawings:
Accompanying drawing 1 is the structural representation of gear train.
Accompanying drawing 2 is synoptic diagram of control module.
Embodiment:
Embodiment 1:
Steel ball sphere expanding unit, its composition comprises: control module, described control module comprises reseting module, the corresponding microcontroller of described reseting module, described microcontroller is corresponding stepper motor I 6, stepper motor II 10, direct current generator 2, Keysheet module respectively, and described control module is connected with gear train.
Described steel ball sphere expanding unit, described gear train comprises: expansion dish 1, rolling disc 9, described expansion dish 1 is connected with the direct current generator 2 with motor cover 3, and described motor overlaps 3 and is connected with closed slide 5, and described closed slide 5 is connected with cam 4;
Described rolling disc 7 is connected with rotor wheel 9, and described rotor wheel 9 outsides are connected with axle sleeve 8.
Described steel ball sphere expanding unit, described stepper motor II 10 is connected with rolling disc 7, and described stepper motor I 6 is connected with described cam 4, and described direct current generator 2 is connected with described expansion dish 1.
The course of work:
Rolling disc is driven by stepper motor two.The expansion dish is by stepper motor I and direct current generator Collaborative Control.Direct current generator makes the expansion dish circular motion that fixes, and the expansion dish rotates always in expansion process, and steel ball is constantly rotated.Stepper motor I carries out intermittence at set intervals and rotates, this rotation is sent on the cam by motor shaft, and cam itself is done eccentric motion, drive level and smooth guide rail and do intermittently translation, the expansion dish that level and smooth guide rail drives on it is done intermittently translation equally, this direction that steel ball is rotated of intermittently moving is vertical with the direction that direct current generator rotates steel ball, form the circumference eccentric motion of steel ball, even steel ball is compared the rotation that the script track has been done an off-centre, steel ball is just done not intermittently circular motion along new track afterwards, reaches the effect that steel ball surface to be detected launches.
Claims (3)
