Description
Technical Field
The invention belongs to the field of mechanical engineering, and relates to an output rocker arm structure with a spring type sensor.
Background
The sensor output rocker arm transmits the displacement of the monitored object (the application scene is an annular groove joint) to the sensor rotating shaft through the output rocker arm accurately. However, in engineering application, in consideration of the problems of large processing difficulty and difficulty in assembly, a gap often exists between the ring groove joint and the short ball head rod, so that a 'virtual position' often exists when the axial displacement of the ring groove joint is monitored, and the displacement of the ring groove joint cannot be accurately monitored.
Disclosure of Invention
The purpose of the invention is as follows:
the invention provides an output rocker arm with a spring type sensor, which can eliminate a gap between an annular groove joint and a short ball head rod by applying a spring early warning force, and can finally accurately monitor the displacement of the annular groove joint.
The technical scheme adopted by the invention is as follows:
a spring type sensor output rocker arm comprises a short ball head rod 1, a sensor rocker arm 2, a ring groove joint 3 and a rotating shaft 6;
one end of the short bulb rod 1 is connected with the sensor rocker arm 2 in a flaring fastening mode, the other end of the short bulb rod 1 is clamped into a clamping groove of the annular groove joint 3 in a clearance fit mode, and a rotating shaft 6 of the sensor is connected with the sensor rocker arm 2.
The rotating shaft 6 of the sensor is connected with the sensor rocker arm 2 through locking of a hexagonal head screw 7.
When the annular groove joint 3 generates axial displacement, the displacement of the annular groove joint 3 is transmitted by the short ball head rod 1, the sensor rocker arm 2 and the rotating shaft 6 of the sensor are driven to deflect, and the sensor deflects through the rotating shaft 6 to monitor the displacement of the annular groove joint (3).
Further comprising: a spring plate 4;
the spring piece 4 is arranged on the sensor rocker arm 2.
The tail end of the spring piece 4 is clamped in the ring groove of the ring groove joint 3.
The spring plate 4 is mounted on the sensor rocker arm 2 by two cap screws 5 and secures the cap screws 5.
The cylindrical head screw 5 is glued and prevented from loosening.
The spring piece 4 is made of spring steel.
The invention has the beneficial effects that:
according to the invention, through a mode of applying the spring early warning force, the gap between the ring groove joint and the short ball head rod can be eliminated, and finally, the displacement of the ring groove joint can be accurately monitored.
Drawings
FIG. 1: the invention discloses a structure diagram I of an output rocker arm with a spring type sensor.
The sensor comprises a short ball head rod 1, a sensor rocker arm 2, an annular groove joint 3, a spring piece 4, a cylindrical head screw 5, a rotating shaft 6 and a hexagonal head screw 7.
FIG. 2: the invention relates to a structure diagram II of an output rocker arm with a spring type sensor.
Detailed Description
The invention is described in further detail below with reference to the drawings.
As shown in fig. 1 and 2, the output rocker arm with the spring type sensor comprises a short ball head rod 1, a sensor rocker arm 2, an annular groove joint 3, a spring piece 4, a cylindrical head screw 5, a rotating shaft 6 and a hexagonal head screw 7.
One end of the short bulb rod 1 is connected with the sensor rocker arm 2 in a flaring fastening mode, the other end of the short bulb rod 1 is clamped into a clamping groove of the annular groove joint 3 in a clearance fit mode, and a rotating shaft 6 of the sensor is connected with the sensor rocker arm 2 through locking of a hexagonal head screw 7. When the annular joint 3 takes place axial displacement, the displacement that the annular joint 3 was connected can be transmitted by short bulb pole 1 to drive sensor rocking arm 2, the pivot 6 deflection of sensor, the sensor can monitor the displacement that the annular connects 3 through the 6 deflections of pivot.
In order to eliminate the gap between the short ball rod 1 and the annular groove joint 3, after the position of the spring piece 4 is adjusted as required, the spring piece 4 is arranged on the sensor rocker arm 2 through two cylindrical head screws 5, glue is coated on the cylindrical head screws 5 for preventing looseness, and finally the tail end of the spring piece 4 is clamped in the annular groove of the annular groove joint 3.
The working principle is as follows: because the pretightning force that spring leaf 4 exerted makes the annular connect 3 and the clearance between the short bulb pole 1 eliminated, consequently when annular connects 3 and takes place axial displacement, the displacement transmits the one end of sensor rocking arm 2 through short bulb pole 1 to make sensor rocking arm 2 revolve around pivot 6 rotatory, the sensor can record the rotation amount of sensor rocking arm 2 through the rotation of pivot 6, can obtain the axial displacement that the annular connects 3 through the conversion.
