Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a microscopic detection device for high-precision tapered roller bearings. Background Art

[0002] Tapered roller bearings belong to separable bearings. Both the inner and outer rings of the bearings have tapered raceways. Such bearings are divided into different structural types such as single-row, double-row, and four-row tapered roller bearings according to the number of rows of rollers installed.

[0003] At present, most of the existing detection devices for tapered roller bearings clamp the bearings from the outside or inside. And to ensure the stability of clamping, multiple clamping blocks are used on the devices, so that the clamping force can be implemented in multiple directions. However, at present, most of the multiple clamping blocks on the market are separately contracted, which undoubtedly reduces the work efficiency.

[0004] Therefore, we propose a microscopic detection device for high-precision tapered roller bearings. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a microscopic detection device for high-precision tapered roller bearings.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A microscopic detection device for high-precision tapered roller bearings includes a workbench and a turntable above the workbench. A rotating rod is rotatably installed inside the workbench, and the rotating rod extends outside the workbench. One end of the rotating rod is fixedly installed with the turntable through a connecting plate. At least three rollers are rotatably connected inside the turntable. One end of each roller is connected with a clamp through a connecting plate. The clamp is used for clamping the inner circle of the bearing. The connecting plate is located between the turntable and the workbench.

[0008] As a further scheme of the utility model: At least three arc-shaped holes are formed on the upper surface of the turntable. One side surface of the arc-shaped holes is in rolling connection with the rollers. The lower end of the roller is rotatably connected with the connecting plate. The connecting plate is fixedly connected with the clamp.

[0009] As a further scheme of the utility model: At least three sliding grooves are formed on the upper surface of the workbench. A sliding block is fixedly installed on the lower surface of the connecting plate. One side surface of the sliding groove is in sliding connection with the sliding block.

[0010] As a further solution of the present utility model: A connecting block is fixedly installed inside the workbench, a first electric telescopic rod is fixedly installed on one surface of the connecting block, and a gear plate is fixedly installed at one end of the first electric telescopic rod away from the connecting block.

[0011] As a further solution of the present utility model: The gear plate is meshed with a gear, and the gear is fixedly connected with the rotating rod.

[0012] As a further solution of the present utility model: An auxiliary block is fixedly installed on one surface of the workbench, a driving device is fixedly installed below the auxiliary block, and a rotating shaft is fixedly installed at the output end of the driving device.

[0013] As a further solution of the present utility model: The rotating shaft extends outside the auxiliary block, a second electric telescopic rod is fixedly installed at one end of the rotating shaft away from the driving device, and the second electric telescopic rod is connected with an observation device through a top plate.

[0014] Compared with the prior art, the present utility model provides a microscopic detection device for high-precision tapered roller bearings, which has the following beneficial effects:

[0015] In the present utility model, when the driving device works, the rotating rod rotates, and the rotating rod is fixedly installed with the turntable through the connecting disk. Therefore, when the rotating rod rotates, it drives the turntable to rotate, and then drives the rollers rolling inside the turntable to roll, and further drives the connecting plate and the fixture connected with the rollers to move. Thus, after the three fixtures move closer to the middle, through the rotation of the rotating rod, the three fixtures move outward, so as to clamp the tapered roller bearing from the inside, and the three fixtures work simultaneously, improving the working efficiency.

[0016] In the present utility model, when the staff starts the driving device, the rotating shaft rotates, and then drives the second electric telescopic rod to rotate. At the same time, one end of the second electric telescopic rod away from the rotating shaft is fixedly installed with a top plate, and an observation device is fixedly installed at the other end of the top plate. Therefore, when the second electric telescopic rod rotates, it drives the top plate and the observation device to rotate together. At the same time, when the second electric telescopic rod expands and contracts, it drives the top plate and the observation device to lift and lower together, so that the staff can better detect the bearing.

[0017] The parts not involved in this device are the same as or can be implemented by the prior art. The structure of the present utility model is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1: A microscopic detection device for a high-precision tapered roller bearing, as Figures 1 - 4As shown in the figure, it includes a workbench 1 and a turntable 3 above the workbench 1. A rotating rod 17 is rotatably installed inside the workbench 1, and the rotating rod 17 extends to the outside of the workbench 1. One end of the rotating rod 17 is fixedly installed with the turntable 3 through a connecting plate 5. At least three rollers 6 are rollingly connected inside the turntable 3. One end of the roller 6 is connected with a clamp 8 through a connecting plate 7. The clamp 8 is used for clamping the inner circle of the bearing. The connecting plate 7 is located between the turntable 3 and the workbench 1. By setting a driving device fixedly connected with the rotating rod 17, when the driving device works, the rotating rod 17 rotates. And the rotating rod 17 is fixedly installed with the turntable 3 through the connecting plate 5. When the rotating rod 17 rotates, it drives the turntable 3 to rotate, then drives the rollers 6 rolling inside the turntable 3 to roll, and further drives the connecting plate 7 and the clamp 8 connected with the rollers 6 to move. When the three clamps 8 move closer to the middle, through the rotation of the rotating rod 17, the three clamps 8 move outward, so as to clamp the tapered roller bearing from the inside. And the three clamps 8 work simultaneously, improving the work efficiency.

[0026] As Figures 1 - 4 shown, at least three arc-shaped holes 4 are formed on the upper surface of the turntable 3. One side surface of the arc-shaped hole 4 is rollingly connected with the roller 6. The lower end of the roller 6 is rotatably connected with the connecting plate 7. The connecting plate 7 is fixedly connected with the clamp 8. At least three sliding grooves 2 are formed on the upper surface of the workbench 1. A sliding block 701 is fixedly installed on the lower surface of the connecting plate 7. One side surface of the sliding groove 2 is slidably connected with the sliding block 701. By providing three arc-shaped holes 4 on the turntable 3 and the roller 6 being rollingly connected with the arc-shaped holes 4, when the turntable 3 rotates, the roller 6 rolls in the arc-shaped holes 4, driving the sliding block 701 under the connecting plate 7 to slide in the sliding groove 2, and further enabling the clamp 8 fixedly connected with the connecting plate 7 to contract and expand, facilitating the taking and clamping of the bearing.

[0027] Embodiment 2: A high-precision microscopic detection device for tapered roller bearings, as Figures 1 - 4 shown, a connecting block 20 is fixedly installed inside the workbench 1. A first electric telescopic rod 19 is fixedly installed on one side surface of the connecting block 20. One end of the first electric telescopic rod 19 away from the connecting block 20 is fixedly installed with a gear plate 18. The gear plate 18 is meshed with a gear 16. The gear 16 is fixedly connected with the rotating rod 17. By providing the first electric telescopic rod 19 and the telescopic end of the first electric telescopic rod 19 being fixedly connected with the gear plate 18, when the first electric telescopic rod 19 expands and contracts, it drives the gear plate 18 to move horizontally. At the same time, the gear plate 18 is meshed with the gear 16, and the gear 16 is fixedly connected with the rotating rod 17. When the gear plate 18 moves, it drives the gear 16 to rotate, then drives the rotating rod 17 to rotate, and further drives the turntable 3 to rotate.

[0028] AsFigures 1 - 2 As shown in the figure, an auxiliary block 11 is fixedly installed on one side surface of the workbench 1. A driving device 9 is fixedly installed below the auxiliary block 11. A rotating shaft 10 is fixedly installed at the output end of the driving device 9. The rotating shaft 10 extends outside the auxiliary block 11. A second electric telescopic rod 12 is fixedly installed at one end of the rotating shaft 10 away from the driving device 9. The second electric telescopic rod 12 is connected to an observation device 14 through a top plate 13. By setting the driving device 9, and the rotating shaft 10 is fixedly installed at the output end of the driving device 9. At the same time, the rotating shaft 10 is rotatably connected to the auxiliary block 11, and the rotating shaft 10 is fixedly connected to the second electric telescopic rod 12. Thus, when the staff starts the driving device 9, the rotating shaft 10 rotates, and then drives the second electric telescopic rod 12 to rotate. At the same time, one end of the second electric telescopic rod 12 away from the rotating shaft 10 is fixedly installed with a top plate 13, and the other end of the top plate 13 is fixedly installed with an observation device 14. Therefore, when the second electric telescopic rod 12 rotates, it drives the top plate 13 and the observation device 14 to rotate together. At the same time, when the second electric telescopic rod 12 expands and contracts, it drives the top plate 13 and the observation device 14 to move up and down together. Thus, it enables the staff to better detect the bearing.

[0029] Working principle: By setting the first electric telescopic rod 19, and the telescopic end of the first electric telescopic rod 19 is fixedly connected to the gear plate 18. Thus, when the first electric telescopic rod 19 expands and contracts, it drives the gear plate 18 to move horizontally. At the same time, the gear plate 18 is meshed with the gear 16, and the gear 16 is fixedly connected to the rotating rod 17. Thus, when the gear plate 18 moves, it drives the gear 16 to rotate, and then drives the rotating rod 17 to rotate, and further drives the turntable 3 to rotate. The roller 6 rolls in the arc-shaped hole 4, driving the sliding block 701 under the connecting plate 7 to slide in the sliding groove 2, and then enabling the clamp 8 fixedly connected to the connecting plate 7 to contract and expand, facilitating the taking and clamping of the bearing.
