Description
Technical field
The present invention relates to bearing block, more particularly to a kind of bearing block sphere diameter error detection method.
Background technology
The characteristics of rolling bearing units, bearing can realize ± 2 ° of aligning, and the cooperation of bearing block and bearing determines aligning performance
The realization of energy.The spherical outside surface of bearing is process using professional grinding machine, and precision is secure.And bearing block is added using numerical control borer
Work, deviation from spherical form is big, is the whole bottleneck for coordinating and realizing.The spherical control for lifting bearing block is to realize rolling bearing units key performance
Emphasis.Original bearing block spherical diameter measurement method is mainly carried out by three-coordinate instrument, and shortcoming can not adapt to large batch of life
Production, can not popularize uses in production scene, or by inside micrometer, shortcoming measuring speed is slow, and because of bearing block in itself
Structure filling slot be present, sphere is imperfect, cause measurement measure points it is limited, so as to measurement accuracy reduce.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of bearing block sphere diameter error detection method, and it can be fast
Speed measures the torque value of bearing block, so as to judge whether bearing block is qualified, detection more rapid and convenient.
It is to reach above-mentioned purpose technical scheme provided by the invention：A kind of bearing block sphere diameter error detection method, this
Method comprises the following steps：
(1) torque wrench and the ring standard gauge suitable for test bearing seat are selected；
(2) bearing block to be measured is fixed on fixture；
(3) ring standard gauge is put into inner hole of bearing seat mounting groove, the handle end of torque wrench is held by extroversion with finger
Interior force, ring standard gauge is set to be pressed into bearing block sphere；
(4) connector of connection major axis is connected as one with torque wrench；
(5) connection major axis cylindrical end is sticked into ring standard gauge endoporus, first passes through torque wrench and outwards prize ring standard gauge extremely
Extreme position, the dial of torque wrench is then adjusted to zero-bit, it is then horizontal inwardly to prize ring standard gauge to the pole of opposite side
Extreme position, then read dial numerical value；
(6) torque value of bearing block is calculated by formula, judges whether bearing block is qualified by the data of torque value, is counted
It is as follows to calculate formula：
Torque value=torque wrench reading * [(L+Mx)/L], wherein L is to connect the connector of major axis to the handle of torque wrench
The distance between hand end central point, Mx are the connector of connection major axis the distance between to ring standard gauge axis.
Further, the sphere axis of institute's test bearing seat is parallel to the ground in the step (2).
Further, step (5) torque wrench using when need keep level to move.
Compared with prior art, have the advantages that：
The present invention with quick detection and can calculate the torque value of bearing block, so as to judge whether bearing block is qualified, detection
More rapid and convenient, greatly improve operating efficiency.
Brief description of the drawings
Fig. 1 is torque wrench structural representation of the present invention.
The present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, a kind of bearing block sphere diameter error detection method, this method comprise the following steps：
(1) torque wrench 1 and the ring standard gauge 2 suitable for test bearing seat are selected：(2) bearing block to be measured is fixed on folder
On tool, and the sphere axis of institute's test bearing seat is parallel to the ground；(3) ring standard gauge 2 is put into inner hole of bearing seat mounting groove
In, the handle end ecto-entad that torque wrench is held with finger exerts a force, and ring standard gauge 2 is pressed into bearing block sphere；(4)
The connector 31 of connection major axis 3 connects as one with torque wrench；(5) cylindrical end of connection major axis 3 is sticked into ring standard gauge 2
Hole, first pass through torque wrench 1 and outwards prize ring standard gauge 2 to extreme position, the dial of torque wrench 1 is then adjusted to zero
Position, then the horizontal ring standard gauge 2 that inwardly prizes is to the extreme position of opposite side, and then reading dial numerical value, the moment of torsion are pulled
Hand 1 needs keep level to move when using；(6) torque value of bearing block is calculated by formula, is judged by the data of torque value
Whether bearing block is qualified, and calculation formula is as follows：The reading * of torque value=torque wrench 1 [(L+Mx)/L], wherein L are connection major axis 3
Connector 31 to the distance between handle end central point of torque wrench 1, Mx is that the connector 31 of connection major axis 3 arrives standard ring
Advise the distance between 2 axis；It can quickly detect and calculate the torque value of institute's test bearing seat, so as to judge bearing block
It is whether qualified, greatly improve quality inspection work efficiency.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although reference
The present invention is described in detail for preferred embodiment, it will be understood by those within the art that, can be to the present invention's
Technical scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, it all should cover
Among scope of the presently claimed invention.
