Description

Bearing steel ball is tested ball device

Technical field

Whether the utility model relates to the assembly equipment that a kind of bearing uses in automatic production line, for detection of bearing steel ball quantity, lack or the bearing steel ball that has more is tested ball device.

Background technology

After design bearing is good, steel ball number between its inside and outside circle in raceway is changeless, but in the production of bearing, assembling process due to reasons such as equipment fault, human factors, often there is the how many phenomenon of steel ball number to occur, steel ball number number will directly affect quality and safety in utilization and the service life of rolling bearing, therefore in Production of bearing assembling process, test ball operation to be absolutely necessary.

Chinese Patent Application No. 201110327810.4 " a kind of bearing assembly line is with testing ball mould ", provide vacuum generator has been set in frame, by aspirating hole, bearing inside is vacuumized, and set not the force value while lacking ball by control system, Data Comparison, effectively detects bearing by this mould and whether lacks steel ball after tested.But it has also needed a vacuum generator, increased the input of auxiliary equipment.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of bearing steel ball to test ball device, it is simple in structure, and cost of manufacture is low, and can reduce the damage to steel ball, extend bearing service life, greatly improve bearing assemble efficiency, suitable especially bearing automation Assembling Production in enormous quantities is used.

The technical scheme in the invention for solving the above technical problem is: bearing steel ball is tested ball device, comprise that the cylinder with cylinder joint pin is fixed on base plate, lead with test ball mould and connect into integral body, cylinder joint pin coordinates with lead, be connected on top board and die shoe, on described lead, also connect the detection trigger column coordinating with approach switch, the described ball mould lower end of testing is arc surface, in arc surface shape and bearing to be measured, between outer ring, the shape of raceway matches, the maximum radian measure beta of arc surface is by the length computation that lacks one or one above steel ball position in bearing to be measured, the most advanced and sophisticated α cone angle of arc surface is 20～40 degree.

Compared with prior art, the utility model has the advantage of: this apparatus structure is simple, part is few, only with one, be connected with lead and a cylinder of testing ball mould, test ball mould and utilize itself and the deadweight of the lead that is connected, move down after putting in place and just can realize collection ball and test ball, the damage of steel ball and inside and outside circle raceway groove can not occur to cause because of shock, impact phenomenon, and collect that ball precision is high, operating efficiency is high, bearing long service life.

In addition; test the design of ball mould arcwall face length; be by lack a steel ball position and with the making that matches of raceway shape; also by up big and down small curved tapers design; therefore; test ball mould total energy and insert in the neutral gear of raceway between the inside and outside circle of bearing, and the steel ball of putting together rapidly makes its collection ball location, reduced drive unit and more corresponding structures of making to collect ball bearing rotation.Do not need vacuum generator or optical fiber facility etc. to require the input of the auxiliary equipment of high, price, therefore easily make, cost of manufacture is low.

Test ball mould is again gage outfit simultaneously, so it has the dual-use function of collection ball and measurement, the detection mode that ball mould enters bearing height to be measured is tested in utilization, measurement part and connected driving mechanism have been omitted, testing ball mould enters bearing and also by detecting trigger column on lead, enters the detection of bearing height change in location, detecting immediately steel ball is lack or have more, test ball mould and when testing ball, synchronously completed again collection ball task, to test ball, collection ball two procedures one step completes, not only simplify working process but also save time, laborsaving, greatly increase work efficiency and reduce energy consumption, detection is produced in suitable especially bearing automation in enormous quantities, use.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.

Test ball mould 10, requirement according to different size bearing to steel ball varying number, what be made into as required different sizes tests ball mould, and it is cylindrical with the ladder of blind hole testing ball mould upper end, the most advanced and sophisticated α cone angle of arc surface is 20～40 degree, and the height of arcwall face is the summation of each steel ball 15 diameters in bearing 11 to be measured.

The radian measure beta of testing ball mould lower end arcwall face maximum is by the race way shape that lacks a steel ball position in the bearing to be measured design that matches, as shown in Fig. 3, Fig. 8.

Test ball cylinder 4, approach switch 6 is screwed on base plate 8, base plate 8 is arranged on column 9, on lead 2, be screwed and detect trigger column 5, according to the difference of product to be measured, capable of regulating detects height, regulate and detect the position of trigger column on lead, lead 2 is provided with outer the placing at base plate 8 places the linear bearing 7 of being convenient to move up and down, the end of lead 2 is through base plate 8, insertion is tested in the blind hole of ball mould 10 upper end ladder cylinders, will test ball mould 10 be fixed on lead 2 and connect into integral body with limit screw.

Lead top is connected on top board 1 with nut through through hole on top board, and adjusting nut also can regulate the length of lead.

Bearing 11 to be measured is placed on workbench 12, and die shoe is comprised of the shaft shoulder 13 of middle mandrel 14 and top edge, and during work, die shoe is lifted, and at this moment mandrel 14 inserts in bearing inner race axis hole to be measured, and the outer ring of bearing 11 to be measured is shelved on the shaft shoulder 13, as shown in Figure 1.

During use, first the cylinder joint pin 3 of testing on ball cylinder 4 is moved down, by cylinder joint pin 3, by top board 1, drive coupled lead 2, test ball mould 10 integral body under the effect of self gravitation, move down, because testing ball mould by a few steel ball Position Design, so test the tip of ball mould 10, be certain to insert in the raceway between the inside and outside circle of bearing 11 to be measured, and put in place and can not move down as extremely again, the steel ball in bearing to be measured 15 is put together to concentrate is positioned at together simultaneously.

Meanwhile, if test ball mould 10, only can insert on the highly little position of bearing 11 to be measured, detect the position of trigger column 5 higher than the position of approach switch 6, be how spherical state as shown in Figure 6, Figure 7.

If half that test ball mould 10 arcwall faces can be inserted in bearing 11 to be measured, the position of at this moment detecting trigger column 5 flushes with the position of approach switch 6, and detecting trigger column, to be triggered to the lantern festival of approach switch on it bright, is shown as correct status, as shown in Figure 4, Figure 5.

If test ball mould 10, can also continue to move down into certain altitude position along bearing to be measured, at this moment detect the position of trigger column 5 lower than the position of approach switch 6, as shown in Figure 2 and Figure 3, be few spherical state.

Approach switch 6 is delivered to controller by metrical information simultaneously, and detect from lead 2 height that trigger column 5 departs from approach switch 6 positions, both from detect the variation of trigger column 5 positions just can know belong to lack ball or many balls or correctly any situation, as shown in Fig. 2, Fig. 4, Fig. 6.

By detecting qualified bearing, be transported on the next procedure ball-dividing device 16 being fixed on column 9, proceed the processing of next procedure, as shown in Figure 9.
