[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 8As shown, the radial and axial bearing clearance testing integrated machine of the present invention includes a frame 10, a support frame 11 connected to the frame 10, a rotating frame 12 rotatably mounted on the support frame 11, a clamping and fixing structure movable along the height direction of the rotating frame 12, the clamping and fixing structure being used to fix the bearing in a vertical state, a detection structure being provided on the rotating frame 12, the detection structure being used to detect bearing clearance, a connecting frame 13 connected to the rotating frame 12, and a pressing and fixing structure connected to the connecting frame 13, the pressing and fixing structure having both horizontal and vertical states, when the pressing and fixing structure is in the vertical state, it is used to fix the bearing in a horizontal state. The top side of the frame 10 has two symmetrical support and positioning structures. The support and positioning structures are used to support and press the bearing in a horizontal state. A support seat 14 is installed in the middle of the top side of the frame 10. A rotating block 15 is rotatably installed inside the support seat 14. A lifting structure is installed on the rotating block 15. The lifting structure is used to lift the bearing and cooperate with the detection structure to detect the radial and axial clearance of the bearing. A support structure is installed at the end of the rotating block 15. The support structure is used to support the bearing in a transverse state. A support frame 16 is installed on the top side of the frame 10. A telescopic rod 17 is installed on the support frame 16. The telescopic rod 17 and the lifting structure are used to move the inner ring of the bearing when detecting the axial clearance of the bearing.

[0036] Under normal conditions, the rotating frame 12 is in a vertical position, and the detection structure is also in a vertical position. At this time, the inner ring of the bearing in the vertical position is clamped by the clamping and fixing structure, and the detection part of the detection structure is in contact with the outer ring of the bearing. The outer ring of the bearing is pushed by the lifting structure, and the radial clearance of the bearing is detected by the detection structure. When it is necessary to detect the axial clearance of the bearing, the rotating frame 12 drives the connecting frame 13 to rotate 90°. At this time, the clamping and fixing structure is in a vertical position, and then the support and positioning structure supports and positions the outer ring of the bearing. Then, the overall length of the telescopic rod 17 is adjusted so that both ends of the telescopic rod 17 can contact the inner ring of the bearing. Then, the telescopic rod 17 is raised by the lifting structure, and the axial clearance of the bearing is detected by the detection structure.

[0037] It should be noted that the radial and axial clearance detection structure of the bearing adopts an integrated installation method, which makes the device smaller in size. The support frame 16 has a storage slot, and the telescopic rod 17 is placed inside the storage slot.

[0038] like Figures 1-4The clamping and fixing structure includes two guide rails 20 symmetrically installed on one side of the rotating frame 12. The length direction of the guide rails 20 is parallel to the height direction of the rotating frame 12. Each guide rail 20 is slidably connected to a slide block 21. Each slide block 21 is threadedly connected to one side of a clamping threaded rod 22. The length direction of the clamping threaded rod 22 is perpendicular to the height direction of the rotating frame 12. Each clamping threaded rod 22 is fixedly connected to a T-shaped connecting threaded rod 23 at its end. Each connecting threaded rod 23 is threadedly connected to a clamping sleeve 24 on its outer surface. Each clamping sleeve 24 is fixedly connected to a clamping block 25 at its end. A connecting plate 26 is connected to one side of the two slide blocks 21. A displacement adjustment structure 27 is provided on one side of the rotating frame 12. The displacement adjustment structure 27 is connected to the connecting plate 26 and is used to adjust the position of the connecting plate 26.

[0039] Before performing radial inspection on the bearing, first select a clamping block 25 with a suitable diameter according to the size of the bearing inner ring, so that one side of the clamping block 25 can fit against the bearing inner ring. Then, thread the clamping sleeve 24 to the connecting threaded rod 23. Then, adjust the connecting plate 26 and slide 21 to a suitable height through the displacement adjustment structure 27, so that the clamping block 25 is coaxial with the bearing. Then, rotate the two clamping threaded rods 22 respectively, so that the clamping sleeve 24 drives the clamping block 25 to move and make the ends of the clamping block 25 fit tightly against the bearing inner ring. The bearing inner ring is clamped and fixed by the two clamping blocks 25. Then, the bearing outer ring can be lifted by the lifting structure, and the radial clearance of the bearing can be detected by the detection structure.

[0040] It should be noted that the clamping block 25 comes in various specifications and is used to clamp and fix the inner rings of bearings of different specifications. The threaded connection makes it easy to install and remove the clamping block 25, thus facilitating the replacement of clamping blocks 25 with different diameters. The displacement adjustment structure 27 can be a screw drive structure, an electric push rod, or a hydraulic cylinder. If the displacement adjustment structure 27 is a screw drive structure, the nut part of the screw drive structure is connected to the connecting plate 26. If the displacement adjustment structure 27 is an electric push rod or a hydraulic cylinder, the output end of the electric push rod or hydraulic cylinder is directly connected to the connecting plate 26.

[0041] like Figures 1-4 The detection structure includes a mounting base 30 connected to the rotating frame 12. An elastic tube clamp 31 is fixedly installed on one side of the mounting base 30. A connecting bolt 32 is connected to the elastic tube clamp 31. A dial indicator 33 is installed inside the elastic tube clamp 31.

[0042] The position of the dial indicator 33's testing head can be adjusted using the elastic clamp 31 and connecting bolt 32. When testing bearings, adjusting the position of the dial indicator 33's testing head allows the testing head to fit against the outer ring of bearings of different sizes, enabling testing of bearings of various sizes.

[0043] like Figure 1 , Figure 5 and Figure 6 The lifting structure includes a nut 50 rotatably mounted on one side of the rotating block 15. A lead screw 51 is threadedly connected to the inner wall of the nut 50. A lifting head 52 is connected to the end of the lead screw 51. The lifting head 52 is coaxial with the dial indicator 33. A guide connecting rod 53 is fixedly connected to the outer surface of the lifting head 52. A guide groove 151 is provided on one side of the rotating block 15. A part of the guide connecting rod 53 is located inside the guide groove 151 and is slidably connected to the guide groove 151.

[0044] When the bearing is in a vertical position to test the radial clearance of the bearing, the inner ring of the bearing is clamped and fixed by the clamping and fixing structure, and the dial indicator 33 is adjusted to a suitable height so that the testing head of the dial indicator 33 is in contact with the outer ring of the bearing. Then the nut 50 is rotated. At this time, under the guidance of the guide connecting rod 53 and the guide slide 141, the lead screw 51 drives the lifting head 52 to move upward, so that the lifting head 52 lifts the outer ring of the bearing. At this time, the radial clearance of the bearing is tested by observing the dial indicator 33.

[0045] It should be noted that a storage hole is provided on one side of the support base 14, and the lead screw 51 is located inside the storage hole, so that the lead screw 51 can be retracted into the storage hole when not in use.

[0046] like Figure 1 and Figure 3 The clamping and fixing structure includes a support beam 40 connected to the connecting frame 13. The length direction of the support beam 40 is parallel to the length direction of the frame 10. An electric push rod 41 is fixedly installed on one side of the support beam 40. The output end of the electric push rod 41 is connected to a connecting threaded rod 42 with a T-shaped cross-section. A connecting sleeve 43 is threadedly connected to the outer surface of the connecting threaded rod 42. A pressure block 44 is fixedly connected to the end of the connecting sleeve 43.

[0047] The support structure includes a support threaded rod 54 installed at the end of the rotating block 15 away from the nut 50. The outer surface of the support threaded rod 54 is threaded with a support sleeve 55. The end of the support sleeve 55 is connected to a support block 56. The support block 56 is coaxial with the dial indicator 33. A positioning pin 57 is inserted into one side of the support base 14. Two positioning holes are opened on one side of the rotating block 15. The positioning pin 57 is inserted into the interior of the positioning holes.

[0048] When the axial dimension is large, it is inconvenient to test the radial clearance of the bearing by placing it vertically. In this case, the bearing can be placed horizontally. When it is necessary to place the bearing horizontally and test the radial clearance of the bearing, first rotate the rotating frame 12 to rotate the testing structure to a horizontal state, then rotate the rotating block 15 180° so that the support block 56 and the support threaded rod 54 are upward. Then, insert the positioning pin 57 into the interior of a positioning hole to fix the support block 56 in a vertical state. Then, select a support block 56 with a suitable diameter according to the size of the bearing and connect it to the support threaded rod 54 through the support sleeve 55. Then, the bearing can be placed horizontally on the support block 56 so that the support block 56 supports the inner ring of the bearing. Then, adjust the dial indicator 33 to a suitable position according to the size of the bearing so that the testing head of the dial indicator 33 contacts the outer ring of the bearing. Then, the outer ring of the bearing can be rotated and the radial clearance of the bearing can be tested through the dial indicator 33.

[0049] like Figure 1 and Figure 8 The support positioning structure includes a support upright plate 60, a support horizontal plate 61 inserted into the support upright plate 60, a support mounting bracket 62 fixedly connected to one side of the support horizontal plate 61, a clamping threaded rod 63 threadedly connected to one side of the support mounting bracket 62, a clamping block 64 fixedly connected to the bottom end of the clamping threaded rod 63, and a clamping knob 65 threadedly connected to one side of the support upright plate 60. The clamping knob 65 is used to clamp the support horizontal plate 61 so that the position of the support horizontal plate 61 no longer moves.

[0050] When the bearing needs to be placed laterally to test its axial clearance, the support plate 61 is moved so that the support mounting bracket 62 moves the clamping block 64 to a suitable position, ensuring that the inner ring of the bearing corresponds to the position of the dial indicator 33's test head after the bearing is placed laterally on the support plate 61. The height of the dial indicator 33's test head is adjusted so that the test head part of the dial indicator 33 contacts the inner ring of the bearing. Then, the clamping knob is rotated to clamp the support plate 61, preventing it from moving. Finally, the clamping threaded rod 63 is rotated to press the clamping block 64 against the outer ring of the bearing, ensuring that the clamping block 64 does not obstruct the view. The bearing inner ring is then inspected. The overall length of the telescopic rod 17 is adjusted according to the bearing inner ring size. The overall length of the telescopic rod 17 is greater than the inner diameter of the bearing inner ring, so that both ends of the telescopic rod 17 are in contact with one side of the bearing inner ring. Then, the nut 50 is rotated to cause the lead screw 51 to drive the lifting head 52 to rise and lift the telescopic rod 17. The movement of the telescopic rod 17 drives the movement of the bearing inner ring. The axial clearance of the bearing is detected using a dial indicator 33. Furthermore, the support sleeve 55 is rotated to cause the support block 56 to rise and contact the telescopic rod 17, thereby driving the movement of the bearing inner ring and detecting the axial clearance of the bearing.

[0051] It should be noted that when the bearing is placed laterally and the axial clearance of the bearing is tested, the support plates 61 contained in the two support positioning structures move different distances, so that the testing head of the dial indicator 33 can contact the inner ring of the bearing.

[0052] like Figures 1-4 A rotary drive structure is provided between the frame 10 and the support frame 11. The rotary drive structure is used to drive the rotating frame 12 to rotate. The drive structure includes a drive motor 70 installed on the top side of the frame 10. The output end of the drive motor 70 is connected to a pulley 71. The pulley 71 is connected to a pulley 72 via a belt drive. A rotating shaft 73 is fixedly connected to the inner wall of the keyway of the pulley 72. The rotating shaft 73 is connected to the rotating frame 12.

[0053] When it is necessary to adjust whether the rotating frame 12 is in a vertical or horizontal state, the drive motor 70 is started, and the rotating shaft 73 drives the rotating frame 12 to rotate under the transmission action of pulley 71, pulley 72 and belt, thereby adjusting the position of the rotating frame 12.

[0054] A support baffle 18 is fixedly connected to one side of the support frame 11, and the support baffle 18 is perpendicular to the support frame 11.

[0055] When the rotating frame 12 is in a horizontal state, it rests on the support baffle 18. The support baffle 18 supports the rotating frame 12, ensuring its stability. When the rotating frame 12 is in a vertical state, the connecting frame 13 rests on the support plate 60, and the support beam 40 rests on the support frame 16. The support plate 60 and the support frame 16 ensure the structural stability of the support beam 40 and the connecting frame 13, making the overall structure of the equipment more stable when performing axial clearance or radial clearance detection operations.
