Abstract
Description
Technical Field
[0001] The present application relates to the technical field of shaft deflection testing, and in particular to a shaft deflection testing device. Background Art
[0002] The principle behind a runout meter involves using two centers to position shaft parts. By rotating the part, a probe directly measures the radial runout of the part in its radial direction. This instrument is specifically designed to measure the radial runout of shaft parts. It works by positioning the shaft part with two centers and allowing it to rotate freely on the instrument. During this rotation, the probe measures the part's radial runout—the change in position of the part in the radial direction. In this way, the runout meter can accurately detect parameters such as radial circular runout, radial runout, ovality, and end face accuracy error of shaft parts.
[0003] In the prior art, the deflection meter is usually large in size, inconvenient to move and carry, and not convenient for testing some smaller shaft parts. Therefore, this application proposes a shaft deflection test device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0030] Reference Figure 1-5 , a shaft deflection testing device, including a fixed plate 1 and a block 18, a fixed platform 3 is welded on the top of the fixed plate 1, a notch 4 is opened on the top of the fixed platform 3, the inner wall of the fixed platform 3 is rotatably connected to a rotating shaft 5, one end of the rotating shaft 5 is fixedly connected to a rotating roller 6, and the other end of the rotating shaft 5 is fixedly connected to a gear 2 8, the outer side of the fixed platform 3 is rotatably connected to a gear 1 7, and the outer side of the gear 1 7 is fixedly assembled with a turntable 23, a circular groove 12 is opened on the top of the fixed plate 1, one end of the inner bottom of the circular groove 12 is fixedly connected to one end of a spring 13, and the other end of the spring 13 is fixedly connected to a gasket 14, the bottom of the block 18 is fixedly connected to an insertion rod 15, the inner wall of the insertion rod 15 is threadedly connected to a stud 16, a rotating plate 19 is installed on the inner wall of the block 18, a connecting rod 20 is installed on the bottom of the rotating plate 19 through a fastening bolt 22, and a pressure wheel 21 is installed on the outer edge of the connecting rod 20.
[0031] See Figure 1 A fixing rod 9 is fixedly installed on the side of the fixed platform 3 close to the rotating roller 6. The outer edge of the fixing rod 9 is slidably connected to the limit plate 10. The outer edge of the fixing rod 9 is threadedly connected with a nut 11. The side of the nut 11 close to the fixing rod 9 fits with the outer side of the limit plate 10, so that the rotatable limit plate 10 is located on the side of the rotating roller 6 away from the rotating shaft 5, which can limit the shaft when viewed from the side, thereby ensuring the stability of the shaft during the detection process.
[0032] See Figure 4The washer 14 is slidably connected to the inner wall of the circular groove 12, and the insertion rod 15 is also inserted into the inner wall of the circular groove 12. The bottom of the circular groove 12 fits with the top of the washer 14, so that the elastic force of the spring 13 can be used to adjust the washer 14 to different positions on the inner wall of the circular groove 12, thereby facilitating the support of the insertion rod 15 and ensuring that the insertion rod 15 will not fall easily when the stud 16 is tightened. When the stud 16 moves away from the inner wall of the insertion rod 15, the elasticity of the spring 13 can directly push the washer 14 and the insertion rod 15 to move upward, thereby facilitating the adjustment of the depth of the insertion rod 15 in the inner wall of the circular groove 12, and further facilitating the adjustment of the height of the rotating plate 19.
[0033] See Figure 2 and Figure 3 There are two rotating shafts 5, rotating rollers 6 and gear 2 8, and the two rotating shafts 5, rotating rollers 6 and gear 2 8 are symmetrically arranged on both sides of the slot 4. The two gears 2 8 are meshed with each other, and gear 1 7 is meshed with gear 2 8, so that the rotating turntable 23 drives gear 1 7 to rotate, and the gear teeth can be used to drive gear 2 8 to rotate, and the rotational force can be transmitted to the other gear 2 8, so that the two rotating shafts 5 and the two rotating rollers 6 can rotate synchronously to perform testing operations on the axis placed between the two rotating rollers 6.
[0034] See Figure 4 One end of the outer side of the stud 16 is fixedly connected to a rotating column 17, and a plurality of threaded holes are evenly distributed on the inner wall of the circular groove 12. The end of the stud 16 away from the rotating column 17 passes through the inner wall of the insertion rod 15 and is threadedly connected to one of the threaded holes. The rotating column 17 makes it easier to rotate the stud 16, and the height of the insertion rod 15, the block 18 and the rotating plate 19 can be adjusted by threading the stud 16 into threaded holes at different heights, thereby facilitating the adjustment of the height of the pressure wheel 21, and thus being suitable for testing shafts of different diameters.
[0035] See Figure 5 A semicircular groove is provided at the bottom of the rotating plate 19, the connecting rod 20 is arranged on the inner wall of the semicircular groove, and the pressure wheel 21 is arranged in the middle of the two rotating rollers 6, so that the connecting rod 20 can be stably installed on the inner wall of the semicircular groove at the bottom of the rotating plate 19, and then the fastening bolts 22 can be removed to facilitate the removal of the connecting rod 20 and the pressure wheel 21 for replacement.
[0036] See Figure 1 The bottom of the fixing plate 1 is fixedly mounted with the base plate 2 by four symmetrically arranged connecting bolts, so that the gravity at the bottom of the device can be increased and the stability when placed on a desktop for operation can be improved.
[0037] See Figure 4 and Figure 5A square groove is opened at the corner of the fixed platform 3, the circular groove 12 is opened at the bottom of the square groove, and the block 18 is installed at the top of the square groove, so that the installation and positioning of the block 18 can be realized, and the height adjustment of the rotating plate 19 is convenient.
[0038] Working principle: When using the device, first place the device at the place of use, then place the shaft that needs to be viewed from the side in the middle of the two rotating rollers 6, then manually rotate the turntable 23 to drive gear 1 7 to rotate, and use the gear teeth to drive gear 2 8 to rotate, and the rotation force can be transmitted to another gear 2 8, so that the two rotating shafts 5 and the two rotating rollers 6 can rotate synchronously to test the shaft placed in the middle of the two rotating rollers 6, and use the clamping wheel 21 to clamp the top of the side-viewing shaft to ensure that it will not easily deviate during the test, thereby facilitating the testing of small shafts, and compared with the existing technology, there is no need to clamp the two ends of the shaft, which is more convenient and can be rotated at the same time. The movable rotating column 17 can threadably connect the stud 16 to threaded holes of different heights, and the elastic force of the spring 13 can be used to adjust the gasket 14 to different positions on the inner wall of the circular groove 12, thereby facilitating support for the insertion rod 15 and ensuring that the insertion rod 15 will not fall easily when the stud 16 is tightened. When the stud 16 moves away from the inner wall of the insertion rod 15, the elasticity of the spring 13 can directly push the gasket 14 and the insertion rod 15 to move upward, thereby facilitating adjustment of the depth of the insertion rod 15 in the inner wall of the circular groove 12, and further facilitating adjustment of the height of the rotating plate 19, which is suitable for testing shafts of different diameters. By removing the fastening bolts 22, the connecting rod 20 and the pressure wheel 21 can be disassembled and replaced.
