Detailed Description
Fig. 1 shows a test recorder for the grinding depth of a soft belt of a slewing bearing according to the invention, wherein the test recorder has been mounted on an outer ring 8 of the slewing bearing.
According to the utility model discloses a test recorder includes mechanical positioning device and test recording device. The mechanical locating device determines the position of the measuring point in the X, Z and R directions. In the present embodiment, the X direction extends along the radial direction of the outer ring 8 of the slewing bearing, and when a component is referred to as moving along the X direction, that is, the component moves inward or outward along the radial direction of the outer ring 8 of the slewing bearing, the depth direction referred to in this application is the X direction. The Z direction is a direction perpendicular to the surface of revolution of the slewing bearing or an axial direction of the slewing bearing, and when a component is referred to as moving in the Z direction, it means moving upward or downward in fig. 1. The R direction is a circumferential direction along the slewing bearing outer ring 8, and the length direction mentioned in the present application is the R direction.
The test recording device comprises a rotary encoder 1, a displacement sensor 15, a touch screen 4, a transmitter (not shown) and a single chip acquisition system (not shown).
The mechanical positioning device extends along a displacement sensor rotating shaft 14 in the R direction, and a first rolling pin shaft 9 and a second rolling pin shaft 17.
In the assembled state shown in fig. 1, the test recording device is arranged on the end face of the slewing bearing outer ring 8. As shown in fig. 1, the first rolling pin 9 and the second rolling pin 17 of the test recording apparatus are fixed on the same side of the mounting case 7 of the test recording apparatus. Furthermore, the test recording device is magnetically attracted to the radially inner side of the slewing bearing outer ring by the first rolling pin 9 and the second rolling pin 17, so that the test recording device is positionally fixed in the X direction and the Z direction with respect to the slewing bearing outer ring 8, and is slidable in the R direction along the radially inner side of the slewing bearing outer ring 8 by means of the first rolling pin 9 and the second rolling pin 17. For this reason, the first rolling pin 9 and the second rolling pin 17 may have magnetic rollers inside, or may be made of magnetic materials. Here, it is also conceivable that the test recording device is magnetically attracted to the radially outer side of the slewing bearing outer ring by the first rolling pin 9 and the second rolling pin 17, and that the test recording device is slidable in the R direction along the radially outer side of the slewing bearing outer ring 8 by the first rolling pin 9 and the second rolling pin 17.
The stroke of this sliding movement of the test recording device along the circumferential direction of the outer ring 8 of the slewing bearing is recorded by the rotary encoder 1. The rotary encoder 1 is mounted on the first rolling pin 9 through the rotary encoder mounting adapter 2. When the first rolling pin shaft 9 rolls in the sliding process, the rotary encoder 1 is driven to rotate at the same time, and therefore the rotary encoder 1 records the rolling of the first rolling pin shaft 9, namely the sliding stroke of the test recording device, namely the polishing length of the soft belt. The second rolling pin 17 rolls in synchronism with the first rolling pin 9. In an embodiment not shown, a low-speed dc motor may be installed on the second rolling pin 17 to drive the second rolling pin 17 to roll, so as to drive the first rolling pin 9 to roll synchronously, thereby avoiding manual sliding by manpower.
The mechanical positioning device further comprises a sliding rod assembly used for adjusting the position of the test recorder in the axial direction of the slewing bearing and a sliding block assembly used for adjusting the position of the test recorder in the radial direction of the slewing bearing. The slide rod assembly and the slide block assembly are fixed on the same side of the installation box body 7, on which the first rolling pin shaft 9 and the second rolling pin shaft 17 are arranged. The slider bar assembly has an X-axis optical axis 10 on which the X-axis slider 3 is slidably disposed and whose position in the X direction is fixed by an X-axis stopper 11 and an X-axis lock nut 12. The slide bar assembly has a Z-axis slide bar 16. The Z-axis slide bar 16 passes through the X-axis slider 3 and is slidably connected to the X-axis slider 3 along the Z-direction. The Z-axis slide 16 is also secured in its position in the Z-direction by a corresponding lock nut. The displacement sensor 15 is connected to the Z-axis slide bar 16 through the rotary bearing 13 and the displacement sensor rotary shaft 14 and is arranged on the centerline of the first rolling pin 9 and the second rolling pin 17, thereby ensuring that the displacement sensor 15 passes through the center of gyration of the slewing bearing. The displacement sensor 15 is configured for recording the soft belt sanding depth. The displacement sensor 15 is preferably an LVDT displacement sensor. Therefore, the rotation axis of the displacement sensor 15 is adjusted to be positioned at the circle center of the circular arc of the raceway through the movement of the X-axis sliding block 3 and the Z-axis sliding rod 16, and the displacement sensor 15 can be rotated through the displacement sensor rotating shaft 14, so that the test position can be adjusted quickly.
In the test process, firstly, the X-axis sliding block 3 and the Z-axis sliding rod 16 are moved, the displacement sensor rotating shaft 14 is moved, the displacement change of the displacement sensor 15 is observed, when the displacement change is very small, the displacement change is the arc circle center of the raceway, the positions of the X-axis sliding block 3 and the Z-axis sliding rod 16 are fixed through corresponding locking nuts, and the displacement sensor rotating shaft 14 is adjusted to the position to be measured so as to measure the grinding depth of the raceway. The value of the grinding depth of the raceway is transmitted to a non-shown singlechip synchronous acquisition system in the installation box body 7 in a signal form through a non-shown transmitter.
After the polishing depth of one raceway is measured, the testing device can be manually pushed to slide along the circumferential direction of the outer ring of the slewing bearing. Here, the position of the entire test device relative to the outer ring of the slewing bearing is ensured by the magnetic attraction of the first rolling pin 9 and the second rolling pin 17 without manually pressing the test device, so that additional unstable radial forces are eliminated. In the process, the first rolling pin shaft 9 synchronously drives the rotary encoder 1 to rotate, and the rotation stroke of the rotary encoder 1 is transmitted to a single chip microcomputer synchronous acquisition system which is not shown and is arranged in the installation box body 7 in a signal mode through a transmitter which is not shown. Therefore, the single chip synchronous acquisition system records signals of the rotary encoder 1 and the displacement sensor 15, and displays data, a grinding profile and a test curve on the touch screen 4.
It is to be noted that the test recorder according to the invention can also be fitted on the inner ring of the slewing bearing and have a suitable construction and operating principle for measuring the corresponding data.
According to the utility model discloses, a degree of freedom for adjusting test record appearance position reduces, and the ascending regulation in X direction and the Z direction is easier, because once adjust can survey a plurality of raceway surface degree of depth. The same raceway can be positioned once, and the test at any position can be realized only by rotating the rotating shaft 14 of the displacement sensor. In this embodiment, the single chip is used for collecting and processing sensor data, and a touch screen is arranged on the cover plate 5 of the mounting box 7 for displaying, recording and storing test curves, and corresponding instructions and parameters can be input through the touch screen. From this, according to the utility model discloses a test record appearance not only automatic recording raceway face degree of depth, still record simultaneously and show the test curve of raceway degree of depth and length and the profile of polishing. In addition, the test recorder does not need to be manually compressed, so that extra unstable radial force is eliminated, and the test accuracy is improved.
The above embodiments are merely for illustrative purposes to illustrate the present invention, but the present invention is not limited to the above embodiments. On the basis of the embodiments described, a person skilled in the art will be able to make any modifications, alterations or combinations of the features illustrated in the present description without departing from the scope of the invention.
