Description

Technical Field

[0001] The utility model relates to the technical field of raceway detection equipment, in particular to a raceway detection device for a slewing bearing. Background Art

[0002] Existing slewing bearings usually come with raceways of corresponding sizes. For slewing bearings that bear large radial loads, certain initial axial and radial clearances must be ensured during design. The size of the slewing bearing clearance depends on the mating accuracy between the inner and outer raceways of the slewing bearing. Therefore, before assembling the slewing bearing, it is necessary to detect the raceway to avoid unevenness in the groove body, which affects the later rotation effect. When an operator detects the raceway, it is first necessary to fix it to prevent deviation during detection, which affects the detection data. However, existing detection devices can often only fix raceways of the same size, and it is difficult to centeringly fix the raceway. The operator needs to make multiple adjustments, thereby reducing the applicability of the product and the detection efficiency, and bringing inconvenience to the daily use of the operator. Therefore, it needs to be improved. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a raceway detection device for a slewing bearing, which has the advantage of centering and fixing raceways of various sizes.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting the extrusion shaft, round shaft, extrusion block and screw, since the screw is threadedly sleeved with the extrusion block, when the screw rotates, it will drive the moving block to move through the extrusion block. Due to the limitation of the limiting block, at this time, the extrusion block will drive the moving block to move backward. At the same time, the extrusion block will extrude the round shaft during the backward movement, so that the round shaft drives the round plate to rotate around the fixed shaft as the axis.

Subsequently, the movable block will squeeze the pressure sensor during the movement, and at this time, the pressure sensor will issue an alarm, so as to be able to automatically detect the flatness of the inside of the raceway.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, the present utility model provides a slewing bearing raceway detection device, including:

[0025] Base 1, on the top of the base 1, a workbench surface 2 is fixedly installed. On the top of the workbench surface 2, an arc groove 3 is opened, and inside the workbench surface 2, a fixed shaft 4 is fixedly sleeved;

[0026] Fixing mechanism, which is arranged at the bottom of the workbench surface 2;

[0027] Among them, the fixing mechanism includes a circular plate 5. The top end of the circular plate 5 is movably connected to the bottom end of the workbench surface 2. The inner part of the center of the circular plate 5 is movably sleeved with the outer surface of the bottom end of the fixed shaft 4. The inner part of the circular plate 5 is movably connected with an extrusion shaft 6. The outer surface of the extrusion shaft 6 is movably connected with the inner part of the arc-shaped groove 3. The bottom end of the circular plate 5 is fixedly installed with a circular shaft 7. The outer surface of the circular shaft 7 is movably connected with an extrusion block 8. The top end of the extrusion block 8 is fixedly installed with a moving block 9. The outer surface of the moving block 9 is movably connected with a limiting block 10. The top end of the limiting block 10 is fixedly connected to the bottom end of the workbench surface 2.

[0028] Due to the limitation of the limiting block 10, the moving block 9 can only move back and forth. When the extrusion block 8 drives the moving block 9 to move backward, at this time, the extrusion block 8 will extrude the circular shaft 7 during the backward movement, so that the circular shaft 7 drives the circular plate 5 to move. At this time, the circular plate 5 will rotate around the fixed shaft 4 as the axis. At the same time, the inside of the circular plate 5 will extrude the four extrusion shafts 6, so that the four extrusion shafts 6 move along the inside of the four arc-shaped grooves 3. At this time, the four extrusion shafts 6 will clamp the raceway during the movement.

[0029] Among them, a fixing plate 11 is fixedly installed on the left side of the bottom end of the workbench surface 2. A screw rod 12 is movably sleeved inside the fixing plate 11. The outer surface of the screw rod 12 is threadedly sleeved with the inside of the extrusion block 8. The front end of the screw rod 12 is fixedly installed with a rocker 13.

[0030] Due to the design of the rocker 13, the operator can drive the screw rod 12 to rotate through the rocker 13. Since the outer surface of the screw rod 12 is threadedly sleeved with the inside of the extrusion block 8, when the screw rod 12 rotates, it will drive the extrusion block 8 to move. At this time, the extrusion block 8 will drive the moving block 9 to move backward along the inside of the limiting block 10.

[0031] Among them, a fixing frame 14 is fixedly installed on the top end of the workbench surface 2. The inner part of the top end of the fixing frame 14 is fixedly sleeved with a first air cylinder 15.

[0032] When the first air cylinder 15 operates, at this time, the first air cylinder 15 will drive the object located at its bottom end to move downward.

[0033] Among them, a driving motor 16 is fixedly installed at the bottom end of the first air cylinder 15. The other end of the output shaft of the driving motor 16 is fixedly sleeved with a rotating shaft 17.

[0034] When the first air cylinder 15 operates, at this time, the first air cylinder 15 will drive the driving motor 16 to move downward. When the driving motor 16 operates, at this time, the rotating shaft 17 will rotate.

[0035] Among them, a second air cylinder 18 is fixedly installed at the bottom end of the rotating shaft 17. The other end of the second air cylinder 18 is fixedly installed with a circular block 19.

[0036] When the rotating shaft 17 rotates, the second air cylinder 18 will rotate driven by the rotating shaft 17. When the second air cylinder 18 operates, the other end of the second air cylinder 18 will drive the round block 19 to move to the right.

[0037] Among them, a pressure sensor 20 is fixedly sleeved on the left side inside the round block 19, and a movable block 21 is movably sleeved on the right side inside the round block 19. A spring 22 is fixedly installed on the outer surface of the movable block 21, and the right end of the spring 22 is fixedly connected to the inside of the round block 19.

[0038] When the right side of the movable block 21 is squeezed, it will move to the left along the inside of the round block 19. At this time, the spring 22 will be in a compressed state. Due to the elastic force of the spring 22, it will play a good reset role in the movement of the movable block 21. At the same time, the movable block 21 will squeeze the right side of the pressure sensor 20 during the leftward movement. Due to the design of the pressure sensor 20, when the pressure sensor 20 is squeezed, it will issue an alarm.

[0039] Among them, a fixed block 23 is fixedly installed at the right end of the movable block 21, and a detection wheel 24 is movably installed inside the fixed block 23.

[0040] When the movable block 21 moves to the right, it will drive the detection wheel 24 to move to the right through the fixed block 23. When the outer surface of the detection wheel 24 contacts the inside of the raceway during the rightward movement, it stops. At this time, the drive motor 16 is started. Then the rotating shaft 17 will drive the whole second air cylinder 18 to rotate. At this time, the detection wheel 24 will detect the raceway during the rotation. When the inside of the raceway is not flat enough, at this time, the detection wheel 24 will be squeezed, so that the movable block 21 moves to the left.

[0041] The working principle and usage process of the present utility model:

[0042] First, the operator places the raceway on the top of the workbench 2. At this time, the operator turns the rocker 13 by hand. Since the screw 12 is movably sleeved with the fixed plate 11, at this time, the rocker 13 will drive the screw 12 to rotate around the movable sleeve joint with the fixed plate 11 as the axis. Since the outer surface of the screw 12 is threadedly sleeved with the inside of the extrusion block 8, when the screw 12 rotates, it will drive the extrusion block 8 to move. At this time, the moving block 9 will move under the drive of the extrusion block 8. Due to the design of the limit block 10, the movement of the moving block 9 will be limited, so that it can only move back and forth. At this time, the moving block 9 will move backward along the inside of the limit block 10 under the drive of the extrusion block 8. At the same time, the extrusion block 8 will extrude the outer surface of the round shaft 7 during the backward movement, so that the round shaft 7 drives the round plate 5 to move. At this time, the round plate 5 will rotate around the fixed shaft 4 as the axis. At the same time, the round plate 5 will extrude and push the four extrusion shafts 6 during the rotation, so that the four extrusion shafts 6 move along the inside of the four arc grooves 3. Subsequently, the four extrusion shafts 6 will clamp the raceway during the movement, thus realizing the function of centering and fixing raceways of various sizes.

[0043] Subsequently, the operator starts the first air cylinder 15. At this time, the bottom end of the first air cylinder 15 will drive the whole driving motor 16 to move downward. Immediately afterwards, the operator starts the second air cylinder 18. At this time, the other end of the second air cylinder 18 will drive the whole round block 19 to move to the right. When the outer surface of the detection wheel 24 contacts the inside of the raceway during the rightward movement, at this time, the operator turns off the second air cylinder 18. Immediately afterwards, the operator starts the driving motor 16. At this time, the rotating shaft 17 will drive the whole second air cylinder 18 to rotate. At this time, the detection wheel 24 will detect the inside of the raceway during the rotation. If the inside of the raceway is not flat enough, at this time, the outer surface of the detection wheel 24 will be extruded by the inside of the raceway during the rotation. At this time, the detection wheel 24 will drive the movable block 21 to move along the inside of the round block 19 through the fixed block 23. Subsequently, the movable block 21 will extrude the pressure sensor 20 during the movement. Due to the design of the pressure sensor 20, when the pressure sensor 20 is extruded, it will emit an alarm, thus realizing the function of automatically detecting the flatness of the inside of the raceway.
