Description
Technical field
The utility model relates to a kind of checkout equipment for the production of ball bearing, the device that particularly a kind of moment of torsion that detects bearing products checks.
Background technology
Ball bearing is mainly used in mechanical swivel bearing, its structure is comprised of outer ring, inner ring, steel ball, retainer, it is produced while assembling, and substantially assembles testing process and is: inner ring is measured---> outer ring measurement---> apolegamy steel ball---> dress steel ball---> and is filled retainer---> grease-added---> dress dust cap---> detection.
Production of bearing out after, also to carry out the inspection of bearing moment of torsion, now main what adopt is two kinds of methods: 1, the method for motor driving weight rotation, 2, adopt the torque sensor mensuration.
Adopt the method for motor driving weight rotation, relatively simple for structure, mainly by weight connecting motor and auxiliary mould parts, formed, its shortcoming is: sample position can't accurately be controlled, cause measuring error large, and, due to structure, can't use while measuring high pulling torque.
Adopt the torque sensor mensuration, by detecting top and rotating bottom two parts, form, top is provided with detection head, detects axle, torque sensor and balance weight body, bottom is provided with inner ring rotating mould and motor, its shortcoming is: when carrying out torque measurement, need to configure according to the difference of the large ting model of bearing the counterweight of Different Weight, and torque sensor to measure interior support be the plain bearing structure, therefore flexible configuration on request.
Summary of the invention
For addressing the above problem, reach and carry out the inspection of high-precision bearing moment of torsion, improve the quality of product, boost productivity, the utility model provides a kind of high-precision bearing moment of torsion testing fixture, by detecting top and rotating bottom two parts, form, detect top and be provided with detection head, detect axle, sensor and balance weight body, described detection head is by detecting axle and sensor, balance weight body connects, the rotation bottom is provided with rotating mould, turning axle, motor, drive the rotation of turning axle driven rotary mould by motor, it is characterized in that: described detection axle is connected with air bearing, described sensor is a kind of pressure transducer, described air bearing top also is equipped with an arm of force and acts on the sensor.
As the further improvement of above-mentioned technology, described rotation motor adopts shaft coupling to be connected with turning axle.
After adopting said structure, the inner ring of driving bearing (or outer ring), balance weight body brings pressure to bear on outer ring (or inner ring) by detecting axle, friction force between inside and outside circle passes to the signal of a power of sensor by air bearing, utilize principle of moments, according to program, calculate torque value really and accurately, adopt air bearing as the counterweight carrier, the counterweight of joining on request Different Weight on its top, adopt air bearing also to approach zero to measuring the error produced.
The utility model is simple in structure, practical, has reached bearing is carried out to the inspection of high-precision bearing moment of torsion, improves the quality of product, enhances productivity.
The accompanying drawing explanation
Fig. 1 is the utility model structural diagrams intention,
Fig. 2 is the utility model structural top structural diagrams intention.
In figure, be denoted as: 1 detects top, 2 rotation bottoms, 11 detection heads, 12 detection axles, 13 sensors, 14 balance weight body, 15 air bearing, 16 arm of forces, 21 rotating moulds, 22 turning axles, 23 motors, 24 shaft couplings, 3 inner rings, 4 outer rings.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not form any restriction of the present utility model.
As shown in Figure 1, 2:
A kind of high-precision bearing moment of torsion testing fixture, by detecting top 1 and rotating 2 liang of bottoms part, form, detect top 1 and be provided with detection head 11, detect axle 12, sensor 13 and balance weight body 14, described detection head 11 is by detecting axle 12 and sensor 13, balance weight body 14 connects, the rotation bottom is provided with rotating mould 21, turning axle 22, motor 23, drive turning axle 22 driven rotary mould 21 rotations by motor 23, it is characterized in that: described detection axle 12 is connected with air bearing 15, described sensor 13 is a kind of pressure transducers, described air bearing 15 tops are equipped with an arm of force 16 and act on the sensor 13.
As further improvement in the technical proposal, described rotation motor 23 adopts shaft coupling 24 to be connected with turning axle 22.
During use, when the automatic conveyance of bearing when detecting station, detection head 11, detect axle 12, sensor 13 and balance weight body 14 move down, detection head 11 is pressed on product end surface, then motor drives 23 by shaft coupling 24 turning axles 22, to drive rotating mould 21 to drive inner ring 3 rotations, because being subject to balance weight body 14 on detection head 11, outer ring 4 exerts pressure, produce the counter-force of the friction force between an opposing inner ring 3 and outer ring 4, this power is by detecting axle 12, air bearing 15, the arm of force 16 passes to the signal of 13 1 power of sensor, utilize the principle of moment, calculate torque value really and accurately according to program.
Adopt air bearing 15 supportings to detect axle 12 as the counterweight carrier, because the frictional resistance of air bearing is almost nil, adopt air bearing also to approach zero to measuring the error produced.
The utility model is simple in structure, practical, has reached bearing is carried out to the inspection of high-precision bearing moment of torsion, improves the quality of product, enhances productivity.
