Abstract
The utility model discloses a kind of bearing steel ball surface defect detection apparatus, mainly include feeding mechanism, unfolded surface testing agency and mechanism for sorting；Feeding mechanism, which realizes, carries out single steel ball charging for unfolded surface testing agency, and unfolded surface mechanism realizes the acquisition of steel ball full perficial helical line expansion and steel ball surface information, and mechanism for sorting, which is realized, carries out qualification and underproof classification to the steel ball after detection.
Description
Technical field
The utility model relates to a kind of defect detecting devices, and in particular to a kind of bearing steel ball surface defect detection apparatus.
Background technique
The earliest bearing steel ball surface defects detection mode in China is that worker's naked eyes detect, i.e., steel ball is placed on monitor station
On, the surface of steel ball is put several ten times larger, is visually observed its surface condition, is carried out steel ball by way of worker's manual overturning steel ball
Full Surface testing, the method cause part of the surface by repeated detection or surface it is difficult to ensure that the angle overturn every time is identical in this way
The case where missing inspection, occurs, to make surface detection of steel ball quality be affected, and this original detection method is to naked eyes
It damages very big.
Chinese patent (publication number CN201520225765) discloses a kind of expansion wheel apparatus of steel ball surface defect detection,
The main working parts of the device are unsymmetrical double-cone Doubly curved surfaces wheels, the steel ball of rotation expanding wheel frictional force rubbing similarly hereinafter
When deflect, thus complete steel ball surface helix expansion；But the device is perfect not enough, only provides the full table of steel ball
A kind of mode of face expansion, lacks matched steel ball feeding mechanism and mechanism for sorting.
Summary of the invention
The utility model provides a kind of bearing steel ball surface defect detection apparatus, in order to solve above-mentioned existing ask
Topic.
The technical solution of the utility model is: a kind of bearing steel ball surface defect detection apparatus, and principal organ includes charging
Mechanism, unfolded surface testing agency and mechanism for sorting.
The feeding mechanism is made of material feeding box, preceding feed pipe, feeding piston, piston cylinder, piston rod, laggard expects pipe；Into
Hopper shape is infundibulate, and preceding feed pipe is connected material feeding box and piston cylinder, feeding piston and can be moved up and down in piston cylinder, feeding
Hole in piston is through-hole and has constant slope, and gradient is identical as former and later two charging rakes of tubes, and laggard expects pipe one end is connected
The piston cylinder other end leads to Surface testing mechanism；For guarantee to roll into every time Surface testing mechanism steel ball only one, feeding is living
A steel ball can only be accommodated in the through-hole of plug, the diameter of front and back feed pipe is identical and single steel ball is only allowed to pass through.
The unfolded surface testing agency by driving wheel, support opinion, unsymmetrical double-cone Doubly curved surfaces wheel, photoelectric sensor,
Eddy current sensor composition；Steel ball rotates under the drive of driving wheel, is supported by support wheel, sends out under the action of expanding wheel frictional force
The deflection of raw certain angle, to realize the helix expansion of steel ball；Pass through photoelectric sensor and whirlpool while steel ball expansion
Flow sensor carries out full surface defects detection to steel ball.
The mechanism for sorting is not conformed to by top discharge pipe, sorting baffle, unqualified steel ball discharge nozzle, qualified steel ball discharge nozzle
Lattice steel ball material storing box, qualified steel ball material storing box composition；Baffle is set between top discharge pipe and qualified steel ball discharge nozzle and can be with
Mobile, baffle gradient discharges with unqualified steel ball, and the rake of tubes is identical, and baffle is chronically at contraction state, when surface detection of steel ball not
Baffle is fallen when qualified；The qualified steel ball in top discharge pipe is strayed into unqualified steel ball discharge nozzle in dropping process in order to prevent,
The diameter of qualified steel ball discharge nozzle is greater than the diameter of top discharge pipe.

Specific embodiment
With reference to the accompanying drawing, it is as follows that the present invention will be further described.
As shown in Fig. 1, steel ball 2 rolls into preceding feed pipe 3 from material feeding box 1 under the effect of gravity；As shown in Fig. 2, when upper
When material piston 4 is located at 5 lower section of piston cylinder, steel ball 2 rolls into feeding piston 4 from feed pipe 3, and piston rod 6 pushes feeding piston 4 upward
Movement, when feeding piston 4 is located at 5 top of piston cylinder, the steel ball 2 in feeding piston 4 rolls into laggard expects pipe under the effect of gravity
7, this process, which completes, carries out single steel ball charging for Surface testing mechanism.
After steel ball 2 enters unfolded surface testing agency, as shown in Fig. 3, steel ball 2 occurs under the drive of driving wheel 14
Rotation, 2 bottom of steel ball are supported by support wheel 15, and unsymmetrical double-cone Doubly curved surfaces wheel 17 makes steel ball under the action of frictional force
Certain angle deflection, so that steel ball 2 be made to realize full perficial helical line expansion；As shown in Fig. 1, in the expansion on steel ball 2 surface
The progress steel ball surface defect detection synchronous with eddy current sensor 16 of photoelectric sensor 18 in the process.
After the completion of the detection of 2 surface spreading testing agency of steel ball, as shown in Fig. 1, support wheel 15 is moved to right, and steel ball 2 is fallen
Enter mechanism for sorting top discharge pipe 13, if 2 Surface testing of steel ball is qualified, baffle 12 is shunk, and steel ball 2 passes through qualified steel ball discharge nozzle
11 enter qualified steel ball material storing box 10；If 2 Surface testing of steel ball is unqualified, baffle 12 falls, and steel ball 2 passes through unqualified steel ball
Discharge nozzle 8 enters unqualified steel ball material storing box 9；The entire detection process of steel ball 2 is completed.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
