Technical Field
[0001] This utility model belongs to the field of bearing testing technology, and in particular relates to a bearing positioning structure for a bearing testing machine. Background Technology
[0002] Bearings are an important component in mechanical equipment, placed between parts that generate relative rotation. Their main function is to support the rotating body of the machine, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. During the production and processing of bearings, they need to be inspected to ensure the overall flatness of the bearing raceway.
[0003] Currently, bearings require inspection during processing. When inspecting the outer wall of the bearing, it is placed on top of the inspection table and then rotated so that the inspection probe can inspect the bearing. However, the bearing may shift during the rotation inspection. Therefore, a bearing positioning structure is needed for the bearing inspection machine. This positioning structure can position the bearing to prevent it from shifting during inspection and ensure the accuracy of the bearing inspection. Utility Model Content
[0004] The purpose of this invention is to provide a bearing positioning structure for a bearing testing machine, which can position the bearing to prevent it from shifting during testing and ensure the accuracy of bearing testing, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bearing positioning structure for a bearing testing machine includes a rotary table rotatably connected to the top of a processing table. The top of the rotary table has four symmetrical sliding grooves. A slider is slidably connected to the inner cavity of the sliding groove. A limit rod is fixedly connected to the top of the slider. A fixing rod is fixedly connected to the top of the inner cavity of the rotary table. A sliding sleeve is fitted on the surface of the fixing rod. A fixing ring is fixedly connected to the top of the sliding sleeve. Four symmetrical connecting rods are rotatably connected to the surface of the fixing ring. The other end of the connecting rod is rotatably connected to the bottom of the slider. A cylinder is fixedly installed at the bottom of the rotary table by bolts. The output end of the cylinder passes through the rotary table and is fixedly connected to the sliding sleeve.
[0006] Preferably, a toothed ring is fixedly connected to the surface of the rotary table, and the toothed ring is located in the inner cavity of the processing table.
[0007] Preferably, a fixed frame is fixedly connected to the top of the inner cavity of the processing table, and a gear is rotatably connected to the bottom of the inner cavity of the fixed frame, the gear meshing with a gear ring.
[0008] Preferably, the motor is fixedly mounted on the bottom of the mounting bracket by bolts, and the output shaft of the motor passes through a gear and is fixedly connected to the mounting bracket.
[0009] Preferably, the top of the processing table is provided with two identical detection probes, and the surface of the slider is fixedly connected with two symmetrical limiting blocks, which are adapted to the slide groove.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model involves mounting the bearing on the surface of four symmetrical limiting rods, activating the cylinder to push the sliding sleeve and drive the fixed ring upwards, so that the fixed ring pushes the slider through the connecting rod to move. By limiting the sliding groove, the center of the slider is spread out, thus achieving the purpose of positioning the bearing through the positioning structure, avoiding the bearing from shifting during testing, and ensuring the accuracy of bearing testing.
[0012] 2. This utility model uses a combination of a gear ring, a fixing frame, gears, and a motor. When the limit rod fixes the bearing on the top of the rotary table, starting the motor will cause the gear to drive the rotary table to rotate through the gear ring, allowing the detection probe to detect the bearing. This avoids the need for the user to manually rotate the bearing, saving labor costs. Attached Figure Description

[0020] In the following description, embodiments of the bearing positioning structure of the bearing testing machine of this utility model will be described with reference to the accompanying drawings.
[0021] Example 1:
[0022] Figure 1-4This invention illustrates a bearing positioning structure for a bearing testing machine according to an embodiment of the present invention. It includes a rotary table 2 rotatably connected to the top of a processing table 1. A gear ring 11 is fixedly connected to the surface of the rotary table 2, and the gear ring 11 is located within the inner cavity of the processing table 1. A fixing frame 12 is fixedly connected to the top of the inner cavity of the processing table 1. A gear 13 is rotatably connected to the bottom of the inner cavity of the fixing frame 12, and the gear 13 meshes with the gear ring 11. A motor 14 is bolted to the bottom of the fixing frame 12. The output shaft of the motor 14 passes through the gear 13 and is fixedly connected to the fixing frame 12. Through the coordinated use of the gear ring 11, fixing frame 12, gear 13, and motor 14, when the limiting rod 5 fixes the bearing to the top of the rotary table 2, starting the motor 14 causes the gear 13 to drive the rotary table 2 to rotate via the gear ring 11, allowing the testing probe to inspect the bearing. The inspection avoids the need for users to manually rotate the bearing, saving labor costs. The top of the rotary table 2 has four symmetrical sliding grooves 3, and the inner cavity of the sliding grooves 3 is slidably connected to the sliders 4. The top of the processing table 1 is equipped with two identical detection probes. The surface of the sliders 4 is fixedly connected to two symmetrical limit blocks, which are adapted to the sliding grooves 3. The top of the sliders 4 is fixedly connected to a limit rod 5. The top of the inner cavity of the rotary table 2 is fixedly connected to a fixing rod 6. The surface of the fixing rod 6 is fitted with a sliding sleeve 7. The top of the sliding sleeve 7 is fixedly connected to a fixing ring 8. The surface of the fixing ring 8 is rotatably connected to four symmetrical connecting rods 9. The other end of the connecting rod 9 is rotatably connected to the bottom of the slider 4. The bottom of the rotary table 2 is fixedly installed with a cylinder 10 by bolts. The output end of the cylinder 10 passes through the rotary table 2 and is fixedly connected to the sliding sleeve 7.
[0023] Working Principle: When using this invention, the user places the bearing on top of the rotary table 2, so that the bearing is fitted onto the surface of the four symmetrical limiting rods 5. The cylinder 10 is activated, causing it to push the sliding sleeve 7 upwards. This causes the sliding sleeve 7 to push the fixing ring 8 upwards on the surface of the fixing rod 6. The fixing ring 8 then pushes the slider 4 through the connecting rod 9. Through the limiting of the sliding groove 3, the four symmetrical sliders 4 drive the four symmetrical limiting rods 5 to spread outwards, making the limiting rods 5 fit against the inner wall of the bearing, thus fixing the bearing and preventing it from shifting during testing, ensuring the accuracy of bearing testing. The motor 14 is then activated, causing the gear 13 to drive the rotary table 2 to rotate through the gear ring 11, allowing the testing probe to test the bearing. This eliminates the need for the user to manually rotate the bearing, saving labor costs.
[0024] In summary, the bearing positioning structure of this bearing testing machine, by fitting the bearing onto the surfaces of four symmetrical limiting rods 5, and activating the cylinder 10, causes the sliding sleeve 7 to slide upwards, thereby causing the fixed ring 8 to move upwards. The fixed ring 8 then pushes the slider 4 through the connecting rod 9. Through the limiting of the sliding groove 3, the center of the slider 4 is spread out, thus achieving the purpose of positioning the bearing through the positioning structure, preventing the bearing from shifting during testing, and ensuring the accuracy of bearing testing.
